Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a taping generally used for an automatic assembly machine such as a device for mounting a leadless type microelectronic component (hereinafter referred to as a chip component) on a circuit board. The present invention relates to a component supply device.

2. Description of the Related Art Conventionally, a device for supplying a chip component has a lever 3 as disclosed in, for example, Japanese Patent Application Laid-Open No. 57-140000 shown in FIG.
When the tip portion of 0 is pressed in the direction of arrow F with a constant stroke by a separately provided drive unit 31, the ratchet ratchet wheel 33 is rotated by the feed pawl 32 in the direction of arrow G by a predetermined pitch,
The stopper claw 34 meshes with the ratchet ratchet wheel 33 to prevent the ratchet ratchet wheel 33 from rotating in the reverse direction. In this state, when the pressing of the lever 30 is released, the tension spring 36 returns the lever 30 to the original state, and the intermittent feeding is completed during a series of predetermined pitches.

Problems to be Solved by the Invention However, due to the diversified shapes of chip parts, a plurality of types of pitches are accommodated in the tape. For example, there is a need to separate and supply components that are stored and taped at 4 mm pitch, 8 mm pitch, 12 mm pitch, etc. by one device and mount them on a substrate. The stroke of 31 is variable,
A means for selectively operating is provided, or the stroke of the drive unit 31 is made constant, and the lever 30b is moved to the fourth position.
As shown in the figure, it is necessary to use a means for coping with a plurality of types of pitches by separately providing a dedicated feeding device having different shapes. Therefore, there is a drawback that a plurality of types of supply devices must be individually prepared.

In view of the above problems, the present invention provides a feeder for taping components capable of feeding plural kinds of pitches with one kind of feeder.

Means for Solving the Problems In order to solve the above problems, the taping component feeding device of the present invention has a lever provided with a plurality of fulcrum holes.

OPERATION The present invention is a taping component supply device having the above-described configuration, in which the feed pitch can be changed without changing the component by simply selecting the fulcrum hole of the lever.

Embodiment Hereinafter, a taping component supply device according to a first embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a taping chip component supply apparatus according to a first embodiment of the present invention.

The variable pitch lever 2 is rotatably attached to a pin 4 provided on a fulcrum 3 and is urged by a tension spring 5, and is pressed by a separately provided drive unit 1 in the direction of arrow A with a constant stroke. . The rotation of the variable pitch lever 2 is
It is transmitted via a link 6 as the rotation of a plate 10 which is rotatably provided concentrically with a ratchet wheel 9 having a feed claw 8 for feeding the pitch of the tape 7. At that time, the ratchet lever 13 rotatably held by the pin 11 fixed to the plate 10 and biased by the torsion spring 12 idles on the ratchet, and the plate 1 moves in the direction of arrow B.
Rotate with 0. After that, when the pressing force of the drive unit is released, the variable pitch lever is rotated in the opposite direction by the tension spring 5. The force again becomes a rotational force in the direction opposite to the arrow B of the plate 10 via the link 6. At that time, the ratchet lever 13 bites into the ratchet wheel 9, and the ratchet wheel 9 is rotated until the ratchet lever 13 comes into contact with the stopper pin 14 to complete a series of tape feeding operations.

The variable pitch lever 2 and the link 6 are rotatably held by a clamp pin 15. Further, the variable pitch lever 2 is provided with fulcrum holes 16X, 16Y, 16Z at three locations corresponding to three kinds of feed pitches X, Y, Z.
The feed pitch can be changed by simply re-clamping the clamp pin 15 according to the required pitch. FIG. 2 shows a view clamped in another fulcrum hole 16Y. By changing the radius from the pin 4, the rotation angle of the plate 10 changes even if the rotation angle of the variable pitch lever 2 is the same.

Further, in the supply device of the present embodiment, the components in the tape 7 which are intermittently fed in the direction of the arrow C on the tape transport surface 17 are fed to the tape 7 before and after the position where the components are supplied to the separately provided transfer means.
A tape guide 18 provided for preventing a dance is rotatably held at a fulcrum 19 and is provided with a torsion spring 20.
Thus, it is biased in the direction of arrow D. In addition, the stopper lever 21 that prevents the ratchet wheel 9 from rotating in reverse
Is rotatably held by the ash spring 23. When the operator sets the tape, if the stopper lever 21 is pressed in the direction of arrow E,
It becomes possible to push up to the state of 8b, and after releasing the pressing of the stopper lever 21 and then releasing 18b, the stepped portion 21b of the stopper lever 21 contacts the lever portion 18c provided on the tape guide, and the tape Guide 18
Is also in the open state, and has the feature that workability is greatly improved.

In the present embodiment, the plurality of holes are provided in the variable pitch lever 2, but the plate 10 may be provided with a plurality of holes for selection.

FIG. 5 shows a device for supplying taping chip parts according to the second embodiment of the present invention.

In this embodiment, the variable pitch lever 40 is the plate 10 provided in the first embodiment, is rotatably held by the link 41 and the clamp pin 42, and corresponds to three kinds of feed pitches U, V, W. Support holes 43U, 43V,
43W is provided, and the feed pitch is changed only by re-clamping the clamp pin 42 according to the required pitch.

FIG. 6 shows a taping chip component supply device according to a third embodiment of the present invention.

In this embodiment, the feed pitch is made variable by simply changing the mounting position of the roller 52, which receives the force from the separately provided drive unit 51, by the clamp pin 53 in the variable pitch lever 50.

As described above, according to the present invention, the feed pitch can be changed by providing the pitch variable lever having a plurality of fulcrum holes and selecting the fulcrum hole to be held, and various kinds of feeding devices should be prepared. Is unnecessary.
