Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a component supply device using a component supply stake used when assembling an IC (integrated circuit) or the like onto a printed circuit board.

Conventionally, as a component supply device using this type of component supply stake, for example, those shown in FIGS. 1 and 2 are known. FIG. 1a is a perspective view showing a component supply stake 1 molded from resin such as plastic, and FIG. 1b is a view taken from the direction of arrow A. Reference numeral 2 in the figure is a hollow portion for mounting supply components such as ICs (not shown). FIG. 2 is a block diagram showing a take-out device for taking out the stakes 1. In the figure, 3 is a magazine for storing the stakes 1 loaded with parts, and the stakes 1 are stored in layers. Reference numeral 4 denotes a cylinder for taking out an empty stake (lowermost stake) 1a after all the mounted parts have been supplied, and the stake 1a is pushed out by a piston rod 5. Reference numeral 6 designates the entire base, and the dimension B between it and the lower end of the magazine 3 is slightly larger than the height of the stake 1 so that the piston rod 5 can push out the empty stake 1a.

In the component supply device configured as described above, the stand 1 on which supply components such as ICs are mounted is
Several pieces are stored in the magazine 3 in a stacked state. A supplied component, such as an IC, is taken out from the lowest stake 1a in the longitudinal direction of the stake (in the direction perpendicular to the plane of the paper in FIG. 2) by a component removal mechanism (not shown). When all the mounted ICs are taken out, the empty stake 1a is pushed out to the side of the magazine 4 on the opposite side by the piston rod 5. When the piston rod 5 returns to its original position,
The next stake 1 is dropped and the above component feeding operation is repeated.

However, in a component supply device using such a conventional component supply stake, when an empty stake 1a is taken out from the magazine 3, the cylinder 4 pushes the stake 1a to the opposite side of the magazine 3. Because the structure was
It requires a lot of space on the sides of the magazine 3,
Particularly when a large number of different types of parts are required, the entire parts feeding apparatus occupies a large amount of space.

This invention eliminates the above-mentioned drawbacks of the conventional technology.The present invention aims to eliminate the above-mentioned drawbacks of the conventional technology by forming a component supplying stake from an elastic body and providing notches in the longitudinal direction from both ends of the stake to take out the empty stake. It is an object of the present invention to provide a component supply device using a component supply stake that does not require a large space, can shorten the conveyance distance for supplying components, and has an improved assembly speed.

An embodiment of the present invention will be described below with reference to the drawings. Note that the same parts as in the prior art are given the same reference numerals.

FIG. 3 is a perspective view showing the component supply stake 11 according to the present invention. This status 11
is made of an elastic body, and cutouts 12 are provided in the longitudinal direction from both ends of the horizontal wall surface.

FIG. 4 is a configuration diagram showing a take-out device 13 that takes out an empty stake 11a after supplying all the loaded parts. In the figure, 14 supports the stakes 11 provided below both ends of the magazine 3. A support member 15 is a notch provided in the wall surface of the magazine 3 adjacent to the support member 14, 16 is a metal fitting for fixing the magazine 3 to the base 6, and 17 is a front and rear grip for gripping the stake 11a. ,
Openable and closable claws 17 that respectively engage the positions of the notches 15 of the magazine 3 and grip the stakes 11a.
a, 17a and an air chuck 17b for opening and closing the claw. 18a, 18b, 18c,
18d is a link mechanism supporting the grip 17;
Reference numeral 9 is a cylinder for raising and lowering the grips 17, 17.

FIG. 5 shows a cross-sectional view taken along the line -- in FIG. It is constructed so that an opening of dimension C can be formed as shown in FIG. Further, FIGS. 6a and 6b show a side view and a bottom view of the main parts of the magazine 3 that accommodates the stakes 11.

FIG. 7 shows a cross-sectional view taken along the - line in FIG. 4, and FIG. 8 a, b, and c show the empty stake 11a.
The order in which the files are extracted is shown. The position of the grip 17 of the take-out device 13 is such that the claws 17a, 17a match the positions of the notches 15 provided in the wall surface of the magazine 3 when viewed in the longitudinal direction of the stick 11.
That is, when the claws 17a, 17a are closed, the notch 15 of the magazine 3 makes it possible to close the claws 17a to an area smaller than the width of the magazine 3.

The operation will be explained based on the above configuration.

Supply parts, e.g. station 1 equipped with IC
1 are stored in a stacked state in the magazine 3, and the ICs are loaded sequentially from the bottom stack 11a.
is taken out. The stake 11a, which has become empty after all ICs have been taken out, is taken out by the take-out device 13, as shown in FIG. That is, the claws 17a, 17a of the grip 17 enter from the notch 15 of the magazine 3 by the cylinder 19 (a), the claws 17a, 17a are closed by the air chuck 17b (b), and the elastic stick 11a Notch 12
Because it has , its ends are deformed. Then, the stake 1 held by the claws 17a, 17a
1a is taken out from below the magazine 3 (c). FIG. 9 shows a cross-sectional view taken along the - line in FIG. It is smaller than the width C dimension of the opening of No. 14. Therefore, when the cylinder 19 is operated to lower the grip 17 with the claws 17a, 17a closed, the lowermost stake 1
1a inserts the magazine 3 through the opening of the support member 14.
It can be taken out below. At the same time, the upper stake 11 sequentially moves downward, and the mounted components are supplied for assembly of printed boards, etc., and the above component supply operation is repeated.

In addition, the parts supplied by the stand are IC
The present invention is not limited to this, but is also applicable to the case of supplying other parts.

As explained above, according to the present invention, the component supply device has a structure including a component supply stake on which a supply component is mounted, a magazine for accommodating the stake, and a take-out device for taking out the stake from the magazine. In this, the component supplying stake is formed of an elastic body and has a notch in the longitudinal direction from both ends thereof, so that it is possible to supply the mounted components and take out the empty stake downward as it is, Therefore, there is no need to provide a large space for taking out the stakes, which has the effect of reducing the area occupied by the entire device.In addition, the transport distance for supplying parts can be shortened, making it easier to assemble parts. This has the effect of increasing speed.
