Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for feeding chip-shaped components which are arranged in an aligned state, and which feeds the chip-shaped components in an arrangement direction, and also includes a chip-shaped component housed in a hopper portion in bulk. And a component supply device that arranges the components in a line and supplies the components to a predetermined position.

[0002]

2. Description of the Related Art Chip-shaped circuit components used by being mounted on circuits are becoming smaller year by year. In order to mount such chip-like circuit components on a circuit board using an automatic cloak device, a chip-like component supply device has been developed which takes out and supplies chip components in a bulk state in a line. I have.

[0003] In such a chip-like component supply device, the chip-like components are stored in bulk in a hopper having a slope on the bottom surface, and the chip-like components are arranged in a line in a component discharge pipe penetrating the bottom of the hopper. Take out. Further, the chip-like components taken out in a line in the component discharge pipe are horizontally aligned by a component guide, and in this state, the chip-like components are conveyed along the component guide by an endless belt provided below the component guide. Then, in a component take-out section provided at the end of the component guide, chip-like components are taken out one by one by a component chuck and mounted on a circuit board.

A component guide used in such a conventional chip-shaped component supply device has a tunnel-shaped component passage through which the chip-shaped components can pass only in a single line, and the chip-shaped component has the component passage. Move along.
Further, an endless belt for applying a propulsive force to the chip-shaped components arranged in the component guide and feeding the same is a belt made of rubber, plastic or metal, and the component guide is formed so as to constitute the bottom surface of the component passage. It is located directly below. The running endless belt gives propulsive force to the chip-like components in the component guide exclusively through the frictional force between the surface and the chip-like components.

[0005]

The component passage of the component guide in the above-mentioned conventional chip-type component supply device has a small margin with respect to the outer diameter of the chip-type component so that the chip-type component can pass smoothly. It is made with. However, a slight variation occurs in the margin between the chip-shaped component and the component passage due to a variation in the outer diameter dimension of the chip-shaped component and the like. On the other hand, a metal belt or the like is used for the endless belt, but a rubber belt having high flexibility and a high coefficient of friction is generally used. However, the rubber belt is easily deformed, and if it is slightly bent, irregularities are generated on the upper surface of the endless belt, which is the bottom surface of the component passage, and the actual height of the component passage varies. Further, when the surface of the endless belt has irregularities, the frictional force applied to the chip-shaped components also varies, and the propulsion speed of the front and rear chip-shaped components differs.

For these reasons, in the conventional chip-shaped component supply device, chip-shaped components to be conveyed in a line in the component passage overlap one another vertically or overlap obliquely in the component passage. Sometimes. In particular, when a small chip-shaped component is supplied, the chip-shaped component a may be caught between the endless belt and the component passage. In this case, the resistance between the chip-shaped component and the component passage is increased, and a so-called locked state occurs in which the component stops and becomes clogged there. The present invention has been made in view of the above-described problems in the conventional chip-shaped component supply device, and is capable of smoothly conveying the chip-shaped components without overlapping each other, thereby preventing the chip-shaped components from being clogged. It is intended to provide a supply device.

[0007]

According to the present invention, in order to achieve the above-mentioned object, when the chip-shaped components a are conveyed in a line in the component passage 12a of the component guide 12, the chip-shaped components a travel below the component passage 12a. The feeders 14 and 42 are provided with magnets 14a and 42a at intervals along the component passage 12a, and the chip-like component a having a magnetic material in part is fed by the magnetic force of the magnets 14a and 42a.

And the magnets 14a and 42a are moved in the arrangement direction of the chip-shaped components a.

Furthermore, a more specific chip-shaped component supply apparatus according to the present invention comprises a hopper portion 4 for accommodating chip-shaped components a in a bulk shape, and a component discharge for taking out the chip-shaped components a in the hopper portion 4 in a line. A pipe 5, a component guide 12 for arranging the chip-shaped components a taken out in a row in the component discharge pipe 5, and an arrangement of the chip-shaped components a under the component guide 12 and in the component guide 12; Feeders 14, 42 for providing propulsion along the direction, and feeder 1

It is located below. The feeder 14 is composed of a belt provided with magnets 14a at intervals. Further, as another form of the feeder 42, a rotating roller having a band-shaped magnet 42a spirally provided on the surface thereof can be cited.

In such a chip-shaped component supply device, the chip-shaped component a, which has a magnetic material in part, is not a frictional force with the surfaces of the feeders 14 and 42 such as a belt, but a magnetic force of the feeders 14 and 42. 14a, 42a,
Propulsion is given by the movement of the magnets 14a and 42a. For this reason, in each chip-shaped component a conveyed in a line in the component passage 12a of the component guide 12, variation in propulsion force hardly occurs, and there is no difference in the conveyance speed of the chip-shaped component a. Therefore, there is no overlap of the front and rear chip-shaped parts a and no slanting of the chip-shaped parts a in the part passage 12a, and no clogging of the chip-shaped parts a in the part passage 12a occurs. Furthermore, parts passage 1

As shown in FIG. 3A, FIG. 3B shows a state in which the upper end surface of the elevating pipe 6 is drawn below the upper opening of the insertion hole 4c and the upper end opening of the component discharge pipe 5. As described above, when the elevating pipe 6 rises and its upper end surface rises above these openings, the chip-like parts a near the upper opening of the insertion hole 4c of the hopper section 4 are pushed up, and their lump collapses. Subsequently, as shown in FIG. 3 (c), when the elevating pipe 6 descends and the upper end surface thereof reaches almost the same height as the upper opening of the insertion hole 4c and the upper end opening of the component discharge pipe 5, the chip-shaped component is moved. a is lowered accordingly, and some of the chip-shaped components a enter into the component discharge pipe 5 from the upper end thereof. Further, as shown in FIG. 3D, in a process in which the elevating pipe 6 descends and its upper end surface reaches the lowest position, the chip-shaped part a is further lowered, and a part of the chip-shaped part a becomes part. It enters into the discharge pipe 5 from the upper end. By repeating this operation,
Chip-shaped components a enter the component discharge pipe 5 in a line in a vertical direction, and are discharged downward by gravity.

As shown in FIGS. 1, 2, 4 and 5,
A component guide 12 is horizontally arranged below the hopper section 4. The starting point of the component guide 12 on the right end side in FIGS. 1 and 2 overlaps below the pipe holding member 1c. The component guide 12 is made of a non-magnetic material, and has a component passage 12a formed therein. This part passage 1
The starting point portion 2a at the right end in FIGS. 1 and 2 is a vertical hole connected to the lower end of the component discharge pipe 5. Further, a portion extending from the starting point of the component passage 12a to the component extracting portion 12b shown on the right side of FIG. 1 is formed in a tunnel shape provided near the bottom surface of the component guide 12. This part passage 12
a is a long, closed space connected linearly, and in this component passage 12a, the chip-shaped components a are connected in a line and can move only in the connected direction.

At the starting point at the right end of FIGS. 1 and 2 of the component passage 12a, the chip-shaped component a should be conveyed in synchronization with the operation of an intermittent rotation mechanism 17 for rotating a pulley 15 described later. Direction, that is, feeder 14 described later
In the direction in which the chip-like component a is conveyed by
Auxiliary propulsion means for providing a propulsive force to the vehicle is provided. This auxiliary propulsion means comprises, for example, a pusher 39 as shown in FIG. The pusher 39 shown in FIG. 6 reciprocates left and right in FIG. 6 in synchronization with the intermittent movement of the feeder 17 by the crank mechanism 38, and pushes the chip-shaped component a at the tip. Thereby, a propulsive force is given to the chip-shaped component a.

A feeder guide 13 is arranged below the component guide 12, and a groove-shaped guide groove 13a having a constant width and depth is formed in a portion of the feeder guide 13 directly below the component guide 12. . And this guide groove 1
A feeder 14 composed of an endless belt is fitted into 3a and is passed therethrough. As shown in FIG. 5, the width and depth of the guide groove 13a are each slightly larger than the width and thickness of the feeder 14, and the feeder 14 travels in the guide groove 13a without resistance and without rattling. Can be. The width of the feeder 14 traveling in the guide groove 13a is sufficiently larger than the width of the component guide 12a of the component guide 12 thereon.

As shown in FIG. 4 and FIG.
Is formed by embedding small permanent magnets 14a at intervals in the center of the upper surface of a flexible belt base material such as rubber. The permanent magnet 14a has a length of one chip length a.
It is embedded at a pitch of about 4 times, but preferably at a pitch of about 1 to 2 times the length of the chip-shaped component a.

The magnet 14 embedded in the feeder 14
Due to the magnetic field generated from a, the chip-like component a partially including a magnetic material is attracted to the magnet 14a side, and the tip-like component a in the component passage 12a moves in the traveling direction as the feeder 14 travels. Moving. The belt base material may be metal or the like as long as it has flexibility, but it is necessary to use a non-magnetic material.

As shown in FIG. 1, a feeder 14 as an endless belt is wound around a pair of pulleys 15 and 16. The pulley 15 is a main pulley that is intermittently rotated in a counterclockwise direction in FIG. 1 around a shaft 15 a provided on the frame 1 by an intermittent drive mechanism 17, and the pulley 16 is rotated via a feeder 14. This is a driven pulley that rotates intermittently around a shaft 16a provided on the frame 1 in response to this.

As the illustrated rotating mechanism for rotating the pulley 15, an intermittent rotating mechanism 17 using a ratchet mechanism is shown, but the rotating means of the pulley 16 is not limited to this. For example, the pulley 16 may be continuously rotated. As shown in FIG. 7, the intermittent rotation mechanism 17 including the ratchet mechanism
A claw wheel 24 attached to the shaft 15a and fixed to the pulley 15, a driven link 20 rotatably mounted around the shaft 15a, and a rotatably mounted end of the driven link 20 for winding. The pawl 22 meshes with the teeth of the ratchet wheel 24 by the elastic force of the spring 23. Further, a lever 18 serving as a driving link is rotatably provided around a shaft pin 18a provided on the frame 1 away from the shaft 15a to the lower right in FIGS.
A spring 19 (see FIG. 1) is engaged with the lever 18, and the spring 19 is biased to rotate the lever 18 around the shaft pin 18a in a counterclockwise direction. The rotation range of this lever 18 is two stoppers 2
Regulated by 5 and 26. Lever 1 which is the driving link
8 and the driven link 20 are connected by a transmission link 21, and the driven link 20 swings by swinging the lever 18.

In this intermittent rotation mechanism 17, a spring 19
By rotating the lever 18 clockwise around the shaft pin 18a against the elasticity of the lever 18 and then returning it, the lever 18 is repeatedly rotated back and forth within the range regulated by the stoppers 25 and 26. The reciprocating rotation of the lever 18 is transmitted to the driven link 20 via the transmission link 21, and the driven link 20 reciprocates around the shaft 15a. Followed link 2
When 0 rotates in the counterclockwise direction in FIGS. 1 and 7, the ratchet wheel 24 is pushed in that direction by the pawl 22 and the ratchet wheel 24 is rotated by one notch of the tooth. When the driven link 20 rotates clockwise in FIGS. 1 and 7, the pawl 22 rotates against the elastic force of the helical spring 23 and rides over one tooth of the ratchet wheel 24. By repeating this, the ratchet wheel 24 intermittently rotates by one notch of the tooth, and the driving pulley 15 fixed to the ratchet wheel 24 also intermittently rotates. Thereby, the belt 14 moves intermittently.
The movement of the belt 14 is such that the upper side of the belt 14 moves leftward in FIG.

As shown in FIGS. 9 and 10, the upper surface of the component passage 12a formed in the component guide 12 on the terminal end side near the pulley 15 is opened by a length slightly more than one chip-shaped component a. This is the component take-out part 12b. The component take-out part 12b is provided with a stop / separation mechanism 30 for stopping the leading chip-shaped component a sent along the component passage 12a and separating the chip-shaped component a from the subsequent chip-shaped component a. Have been. This stop separation mechanism 30
Is a first stopper 27 for stopping the leading chip-shaped component a sent along the component passage 12a, and a second stopper 27 for stopping the second chip-shaped component a following the leading chip-shaped component a. The stopper 36 and these first stoppers 2
Operation link 32 for operating the operation link 7, and the operation link 32
A swing link 34 for operating the second stopper 36 and a gear 31 for swinging the operation link 32 in synchronization with the intermittent movement of the belt 14 are provided.

As shown in FIG. 8, the gear 31 is connected to the pulley 15
Together with the shaft 15 a and fixed to the pulley 15. Therefore, the gear 31 rotates together with the pulley 15. Uneven teeth are formed on the peripheral surface of the gear 31, and the notch interval between the teeth is the same as the notch interval between the teeth of the ratchet wheel 24. As shown in FIGS. 1 and 8, the operation link 32 is swingably mounted around the coaxial pin 32a by a shaft pin 32a provided below the end of the component passage 12a. As shown in FIG. 8, a spring 33 is engaged on the right side of the operation link 32 in FIG. 8, and the resilient force of the spring 33 causes the protruding portion at the lower left end of the operation link 32 in FIG. It is in contact with the peripheral teeth. Further, as shown in FIG. 9, the distal end of a first stopper 27, which will be described later, contacts the upper left surface of the operation link 32 in FIG.
Is regulated. 9 of the operation link 32.
, A slope surface is formed on the upper right side, and this slope surface is in contact with a slope surface of a projecting portion 34a of the swing link 34 described later.

As shown in FIGS. 9 and 10, the first stopper 27 is provided at the end of the component passage 12a.
The first stopper 27 stops the leading chip-shaped part a of the chip-shaped parts a sent by the belt 14 along the part-shaped path 12a. . The stopper 27 is rotatably attached to the side of the component guide 12 via a shaft pin 27a provided on the side of the end of the component passage 12a. An arm-shaped leaf spring 28 is engaged with the stopper 27. The leaf spring 28 is urged by an elastic force that rotates the stopper 27 counterclockwise around the shaft pin 27a in FIGS. ing. Due to the elasticity of the leaf spring 28, the tip of the stopper 27 abuts on the operation link 32, and its position is regulated. Further, a magnet 29 is buried in the surface of the stopper 27 which is in contact with the chip-shaped component a, and the leading chip-shaped component a sent along the component passage 12a comes into contact with the magnet 29 and is stopped.

The second stopper 36 is a pin-like member having a one-end thicker head at one end, and the other end is inserted into the part notice 12a from a hole provided in the side wall of the part passage 12a. . The tip of the stopper 36 is the component passage 12
The position inserted into a is a position where the second chip component a following the first chip component a stopped by the first stopper 36 stops. A spring 37 is interposed between the head of the stopper 36 and the side wall of the component passage 12a.
Is urged in a direction of pulling out the tip from the component passage 12a.

The swing link 3 for operating the stopper 36
Reference numeral 4 is attached such that the intermediate portion is rotatably supported and both ends swing. One end of the swing link 34 abuts on the head of the stopper 36 and suppresses the stopper 36 against the elasticity of the spring 37. A spring 35 is provided between the other end of the swing link 34 and the outer wall surface of the component passage 12a.
The elastic force of the spring 35 is urged in the direction of pushing the tip of the stopper 36 into the component passage 12a against the elastic force of the spring 37. The moment given to the swing link 34 by the elastic force of the spring 35 is set stronger than the moment given to the swing link 34 by the elastic force of the spring 37. Therefore, the moment given to the swing link 34 by the elastic force of the springs 35 and 37 prevails in the clockwise direction in FIGS. A projecting portion 34 is provided on the opposite side of the swing link 34 from which the spring 35 is engaged.
a is formed, and a slope surface facing the operation link 32 side is formed on the protruding portion 34a. The slope surface of the projecting portion 34a of the swing link 34 is in contact with the slope surface formed on the upper right side of the operation link 32 in FIG. Therefore, when the operation link 32 swings clockwise in FIG. 8 against the elasticity of the spring 33 shown in FIG. 8, the upper portion of the operation link 32 moves rightward in FIG. 10 as shown in FIG. I do. As a result, the operation link 32 pushes the protrusion 34b of the swing link 34 rightward in FIG.
The operation link 34 swings counterclockwise in FIG. 10 along the slope. Thus, the pushing of the tip of the second stopper 36 into the component passage 12a is released.

In the stop / separation mechanism 30, the pawl 24 is intermittently rotated by the pawl 22 shown in FIG. 7, and the pulley 15 is intermittently rotated. The indicated gear 31 rotates intermittently.
Therefore, the operation link 32 swings around the shaft pin 32a due to the unevenness of the teeth on the peripheral surface of the gear 31. The swing of the operation link 32 is performed in synchronization with the intermittent feeding of the belt 14.

The lower left projection of the operation link 32 in FIG.
When the operation link 32 swings clockwise in FIG. 8 against the elasticity of FIG.
As shown in the figure, the position is retracted to the right in FIG. In this position, the first stopper 27 rotates counterclockwise in FIG. 10 with the shaft pin 27a as a fulcrum by the elastic force of the leaf spring 28, and crosses the end of the component passage 12a substantially orthogonally. In this state, the leading chip-shaped component a sent by the belt 14 is
7 and is stopped.

The swing link 34 is pushed counterclockwise in FIG. 10 by pushing the protruding portion 34 against the end of the operation link 32 against the elasticity of the spring 35.
In this state, the pushing of the second stopper 36 is released, and the tip of the stopper 36 is retracted from the inside of the component passage 12 a by the elastic force of the spring 37. Therefore, the chip-shaped component a on the second surface from the top is not stopped by the second stopper 36. For this reason, the chip-shaped components a in the component passage a are pushed by the belt 14 and are arranged in a continuous state.

Next, when the lower left projection of the operation link 32 in FIG. 8 hits the tooth valley of the gear 31, whereby the operation link 32 swings counterclockwise in FIG. The upper part of the operation link 32 is shown in FIG.
As shown in (a) and (b), it moves to the left in FIG. In this position, the first stopper 27 is
9 is rotated clockwise as shown in FIG. 9 with the shaft pin 27a as a fulcrum.
The tip-shaped component a at the tip of the component passage 12a is moved to the left in FIG.

At the same time, as the operation link 32 moves to the left in FIG. 9, the swing link 34 swings clockwise in FIG. For this reason, the second stopper 36 is pushed against the elasticity of the spring 37, and its tip is inserted into the component passage 12a, hits the chip-shaped component a on the second surface from the top and stops it. Therefore, as shown in FIG. 9, the leading component a is separated from the subsequent second component. In this state, the leading chip-shaped component a is picked up by a component chuck (not shown) that moves above the component take-out part 12b, and is conveyed to a predetermined location.

Thereafter, when the operation link 32 returns to the position shown in FIG. 10, the first stopper 27 and the second stopper 36 return to the positions shown in FIG. For this reason, the chip-shaped component a which was second from the top is stopped by the first stopper 27 as the top component. Thereafter, by repeating this operation, the chip-shaped components a are sent one by one, and are taken out one by one by the component take-out part 12b. The destination of the chip-shaped component a is usually a printed wiring board, where the chip-shaped component a is mounted.

FIGS. 11 and 12 show the component guide 12.
Another form of the feeder 42 that feeds a chip-like component a having a magnetic material in part along a tunnel-like component passage 12a provided in the apparatus is shown. The feeder 42 is a long roller that rotates around a shaft 43. Parts guide 12
A roller guide 41 is provided directly below the component passage 12a, and a circular groove-shaped guide 41a is provided directly below the component passage 12a in the roller guide 41.
2 is fitted into the guide 41a. Feeder 4
The second shaft 43 is provided just below the center of the guide 41a, that is, just below the center of the component passage 12a, and rotates the feeder 42 about this.

On the peripheral surface of the feeder 42, the magnet 4 is spirally formed.
When the feeder 42 is rotated by rotation of the feeder 42, the magnet 42a sequentially moves in the longitudinal direction on the peripheral surface of the feeder 42 exposed on the bottom surface of the component passage 12a. The feeder 42 is rotated in a direction in which the spiral magnet 42a moves from directly below the component discharge pipe 5 to the component extracting portion 12b side at a peripheral surface portion near the bottom surface of the component passage 12a. The movement of the magnet 42a in the peripheral portion of the feeder 42 near the bottom surface of the component passage 12a moves the chip-shaped component a partially including a magnetic material.

Unlike the apparatus using the belt-shaped feeder 14 as described above, the apparatus using the roller-shaped feeder 42 does not require a feed mechanism by the pulleys 15 and 16, and the roller-shaped feeder 42 is used. It suffices if there is a rotation mechanism for rotating. Further, in this example, as shown in FIG. 11, air is blown into the starting point side of the component passage 12a in the component guide 12, whereby an auxiliary propulsive force is given to the chip-shaped component a. The auxiliary propulsion means for such a chip-shaped component a is provided at the component take-out portion 12 at the end of the component passage 12a.
The air may be suctioned on the b side.

[0044]

As described above, in the chip-shaped component supply apparatus according to the present invention, the chip-shaped component a having a magnetic material in part is magnetized by the magnets 14a,
The magnet 42a is attracted by the magnet 42a, and a propulsive force is given as the magnets 14a and 42a move. For this reason, variation in propulsion force does not easily occur in each chip-shaped component a conveyed in a line in the component passage 12a of the component guide 12, and there is no difference in the conveyance speed of the chip-shaped component a. Therefore, the front and rear chip-shaped parts a may overlap, or the chip-shaped parts a
Does not become oblique in the component passage 12a or the chip-shaped component a does not bite. Therefore, clogging of the chip-shaped component a in the component passage 12a does not occur. Thereby, the chip-shaped component a can be smoothly transported.
