Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a molding and separating mechanism in an automatic feeding device for electronic components such as DIP type ICs.

BACKGROUND ART FIG. 1 shows a conventional example of a molding/separating mechanism in an automatic electronic component supply device. Part 1 is, for example, a DIP type
A large number of ICs are fed in a series from the supply port 2 of the component supply shooter, are guided by the conveyance guide 3, hit the standby stopper 4, and stop, and are sequentially placed in a pair of upper and lower clamping tables starting with the preceding component. 5 and 6. In other words, this is a mechanism for shaping the component 1 in which the terminal 1a has been misaligned in the previous process and restoring it to a predetermined terminal shape. The clamping tables 5 and 6 are driven by hydraulic cylinders 7 and 8, respectively.

The shaped part 1 is released from the upper and lower clamping by the clamping tables 5 and 6, and immediately after that, when the abutment against the standby stopper 4 is released by the operation of the hydraulic cylinder 4a, it is separated from the succeeding parts row. Then, it further falls and moves on the conveyance guide 3 and reaches the positioning table 9. The component 1 held on the positioning table 9 is controlled to correct its posture together with the positioning table 9 by the operation of the hydraulic cylinder 10, and is on standby in preparation for the next setup process. In this state, the component 1 is held and transported by a moving mechanism such as a general industrial robot hand (not shown), and is mounted at a predetermined position on a printed circuit board or the like. In this way, the mechanism is intended for forming and separating work, which is a pre-process before mounting the component 1 in a predetermined position.

As is clear from the conventional mechanism described above, a large number of drive sources such as hydraulic cylinders are required at important points in the work, and even though the parts 1 to be handled are small, the entire mechanism becomes large and the timing of each work becomes difficult. The disadvantage is that misalignment easily occurs.

For example, by arranging a large number of hydraulic cylinders, the transportation distance for separating the parts 1 into shapes and positioning them on the positioning table 9 naturally becomes longer, resulting in an increase in the supply time spent per part. It becomes. Furthermore, because the parts are dropped, burrs generated in the previous process affect the separation work from the subsequent part row, making it difficult to supply this type of parts. .

Summary of the Invention The present invention improves the problems of the conventional mechanism described above, simplifies the entire mechanism by using a single drive source, and uniformizes the timing of a series of parts operations.
Moreover, it is an object of the present invention to provide a molding and separating mechanism for an automatic component feeding device that realizes prompt and accurate feeding.

To achieve the above object, the present invention provides a set of first driven joint members each having an abutting portion and a supporting portion, the abutting portions facing each other and approaching and separating from each other, and the supporting portion The contact portions are formed so as to face each other so that they approach and move away from each other in contrast to the approach and separation of the contact portions, and each of the contact portions is brought into contact with an operating surface of a single motive joint member that reciprocates. a set of clamping tables carried on each of the carriers, which are moved toward or away from each other, and are configured to clamp-form one of the parts that are continuously supplied when the carriers are moved; There is.

Furthermore, the present invention provides a single second driven joint member that is attached to the set of first driven joint members and has an abutting portion and a support portion and is brought into contact with the operating surface of the driving joint member. The separating table is formed so as to be able to move up and down via the abutting part, and is supported by the supporting part and adjacent to the clamping table. The parts are configured to separate one part from the other parts that follow.

Embodiment Hereinafter, an embodiment mechanism of the present invention will be described in detail with reference to FIGS. 2 to 5. In Figure 2, 11 in the figure is a component, which is a DIP type like the conventional example.
Targeted at IC. Reference numeral 12 denotes a supply port for the parts 11, which are guided by a transport guide 12a in the direction of arrow A and transported by pressurized air or other suitable means. Approximately at the center of the supply port 12, a pair of clamping tables 13 and 14 for clamping molding are arranged above and below in the figure. Both clamping tables 13,
The shape of 14 is illustrated in detail in FIG. 3 taken along the line Y--Y in FIG. 2.

On the other hand, in the central part of the device along the feed direction of the component supply port 12, a single movable member 15, such as a wedge-shaped member or a cam member as shown, is movably provided. It is connected to the piston rod 16a of the cylinder device 16, which is the source, and reciprocates in the left-right direction in the drawing. Further, the driving joint member 15 is formed with a linear cam operating surface consisting of flat portions C ₁ to _{C 5} and sloped portions d ₁ to _{d 4} over substantially the entire length of the side surface in the vertical direction.

The driving joint member 15 is in its original position as shown in FIG. 2, and in this original position, rollers 17 and 18, which are freely rotatable, are sandwiched between flat parts C ₂ and C ₄ of the operating surface parallel to the direction of movement. are in contact with each other. One roller 17 is fixed to a table 19, and this table 19 and the upper clamping table 13 are integrally connected by a connecting member 20 (see FIG. 3), and the driving joint member 15 is moved toward the left in the figure. With the movement of the roller 17, the roller 17 sequentially moves from the slope portion _d4 to the flat portion _C5 and descends, and the clamping table 13 also descends in conjunction with the table 19.

In addition, the other roller 18 is provided with a lower clamping table 14.
are coupled so that, as with the roller 17, the clamping table 14 slides on the upright guide rod 21 shown in FIG. 3 and moves up and down as the driving joint member 15 moves. It's summery.

That is, the driving joint member 15 and a pair of upper and lower clamping tables 1
3 and 14, the driving joint member 15
Rotating roller 17 and table 1 in contact with the operating surface of
9 and the connecting member 20 together constitute a driven joint member on the side of the clamping table 13, and the rotating roller 18, which is in contact with the operating surface, and the clamping table 14 are integrated. In this case, the rotating roller 18 is the clamping table 1
It serves as the third side driven joint member. That is, the upper clamping table 13 is supported and connected to the upper end of the connecting member 20 which is a part of the driven joint member, and the lower clamping table 14
is supported and connected to a rotating roller 18, which is a driven joint member thereof. In this way, the pair of driven joint members corresponding to each of the clamping tables 13 and 14 constitute the first driven joint member of the forming mechanism.

The shape of the clamping table 14 is such that it holds the conveyance guide 12a from both sides and has a wedge-shaped upper end, so that as it rises, the terminals 11a on both sides of the component 11 are spread out and adjusted from an irregular state to a substantially horizontal position. It's becoming like that. In this way, the DIP type of part 11
The IC is provided with terminals 11a on each side and is transported so as to straddle the transport guide 12a. Several presser metal fittings 13a are provided on the clamping table 13 which is interlocked with the roller 17 and are protruded in an unsuitable manner.
As it descends, the upper surface of the component 11 is pressed and held on the conveyance guide 12a. Reference numeral 20 in the figure is the connecting member described above, which includes the table 19 and the clamping table 13.
are connected vertically, and these two members are the driving joint member 15.
As it moves, it will be guided up and down on the slide shaft 21.

Again, in FIG. 2, reference numeral 22 is a separation table disposed at the final end of the conveyance guide 12a, and the part 11 that has been pinched and shaped by the pair of pressure plates 13 and 14 is placed next. This is the location that is pushed out and positioned by the part. That is, the part 11 sent to the separating table 22 after shaping is taken out by a moving mechanism such as a general industrial robot (not shown), and the separating mechanism is used in the process immediately before mounting the part 11 on a predetermined workpiece such as a printed circuit board by the robot. Configure. The separation table 22 is supported on a table 23,
A rotating roller 24 is coupled to this table 23. That is, the table 23 and the roller 24
It constitutes a driven joint member. Further, another rotary roller 25 is fixedly installed on the pedestal 26 so as to face this roller 24, and the drive joint member 15 is placed on this fixedly installed roller 25 with its tip end fixed to a flat portion _C4 . It comes into contact with and is movably supported. The roller 24, which is the second driven joint member, comes into contact with the flat portion _C1 of the driving joint member 15, and the driving joint member 1
5 moves to the left from the flat part C ₁ to the slope part d ₂ ,
By sequentially moving to the flat portion _C2 , the separation table 22 and the table 23 are configured to move up and down integrally.

Regarding the relationship between the separation table 22 and the table 23, the engagement protrusion 23a of the table 23 engages with the locking recess 22a provided at the bottom of the separation table 22, and in this engaged state, the stopper 27 is in contact with. The stopper 27 has the locking recess 22
an engaging part 27 that sandwiches the part a with the engaging protrusion 23a.
a, and a sloped portion 27b that abuts against a small sloped portion _d1 formed at the tip of the driving joint member 15.

Note that the separating table 22 is provided with a protruding piece 22b shown in a partially broken part, and the upper clamping table 13 is provided with a protruding piece 13b, and both protruding pieces 22b, 1
3b is in an engaging/disengaging relationship, and when the clamping table 13 is lowered, the protruding piece 13b pushes out the opposing protruding piece 22b, so that the separation table 22 escapes to the left in the figure. In addition, 28 in the figure is the part 11
It is a stopper to prevent the lifting of
It can be rotated clockwise.

The operations and effects based on the above configuration will be described below. When the first component 11 continuously supplied from the component supply port 12 reaches the position shown in FIG.
The piston rod 16a of the cylinder device 16 moves forward in the left direction in the figure to move the driving joint member 15. Along with this, the roller 18 on the clamping table 14 side starts to come into contact with the sloped part _d3 of the driving joint member 15, and the sloped part
d ₄ comes into contact with the roller 17 on the side of the clamping table 13, so that one of the clamping tables 14 is guided by the guide rod 21 and rises, and the other clamping table 13 is connected to the table 19 via the connecting member 20. In other words, it descends together with the roller 17.

As the clamping tables 13 and 14 rise and fall, the terminals 11a on both sides of the component 11 are expanded outward, and the component 11 at this point is pressed upward. , separated from subsequent parts.

Furthermore, in parallel with the above operation, the clamping table 13 is lowered, so that the protruding piece 13b is brought into contact with the protruding piece 2 of the separating table 22.
2b and begin to push the entire separation table 22 to the left in the figure. With this operation, the clamping table 1
The preceding parts sent after the pinch shaping by steps 3 and 14 are completely separated from other succeeding parts.

At the same time, the stopper 2 that was locking the separation table 22
7, the entire stopper 27 is pushed down due to the engagement of both slope portions 27b and _d1 at the same time as the movement of the driving joint member 15 is started, and the engagement portion 27a at the upper end thereof is pushed away from the engagement protrusion 22a of the separating table 22. It comes off, and the entire separation table 22 becomes movable to the left in the figure as described above. FIG. 4 shows a state in which the above series of operations have been completed.

Next, when the driving joint member 15 further moves to the left, the roller 24 pivotally supported by the table 23 starts to come into contact with the slope portion _d2 , and the separation table 22 moves up along the side wall of the protruding piece 13b together with the table 23. Begin to. At the same time, the lifting prevention stopper 28 also rotates in the clockwise direction. FIG. 5 shows a state in which these operations are completed, and this point becomes the working position for taking out the part 11 by a moving mechanism such as a robot hand.

As described above, the parts 11 are inputted from the supply port 12,
After being pressed and formed by a pair of clamping tables 13 and 14, the operation up to separation and positioning at the next separating table 22 is performed accurately by the forward movement of a single driving joint member 15, and thereafter The series of operations is continuously repeated by the return movement of the motive joint member 15 to the right.

In addition, in the above example, the DIP type in the electronic component
Although ICs are shown here, this is not only DIP type ICs, but also electronic components that are difficult to simply separate vertically, such as those that have burrs on both sides, and those that overlap each other. It may also be provided for separate supply of deformed parts that may fit together. In addition, not only electronic parts but also mechanical parts can be separated and supplied if they meet the above conditions.

Effects of the Invention Therefore, according to the above-mentioned apparatus of the present invention, all of the operations of forming, separating, and positioning parts are performed continuously by driving a single driving joint member, so that the entire mechanism is This method not only enables simplification, but also has the effect of always synchronizing the timing between the above-mentioned operations, and furthermore, since the transport distance per component is very short, the supply speed can be increased.
