Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for simultaneously transporting multiple small pieces using a slide mechanism;
More specifically, a slide mechanism provided at the bottom of a multi-magazine in which many types of small pieces are stacked vertically is used to simultaneously pull out each type of small piece from the multi-magazine one by one, and then remove these pieces from a fixed plate of the slide mechanism. The present invention relates to a method for simultaneously transferring multiple small pieces to the next process.

To fabricate a hybrid integrated circuit, it is necessary to attach a large number and variety of circuit elements to fixed positions on a substrate.

With the development of the electronic industry, the demand for producing identical hybrid integrated circuits has increased, and the number of such hybrid integrated circuits may reach hundreds or even thousands.

For this reason, an automated device for simultaneously attaching a large number of circuit elements to a substrate is required, and some of these devices are in practical use.

The basic configuration of a conventional automatic mounting device is as follows.

That is, for each circuit element to be mounted on a board, the circuit elements are stacked vertically and housed in a magazine, and the magazines are arranged in parallel so that the circuit elements are in the same positional relationship as when mounted on the board. A multi-magazine is used, from which each m element is sucked one by one by a suction means while maintaining their relative positions, and transported and mounted to the substrate position.

Many conventional automatic mounting apparatuses employ a method of directly sucking each circuit element one by one from the upper side of a multi-magazine using a sucking means.

However, such an apparatus has the disadvantage that cold press bonding between the circuit elements by the electrode portions occurs, and that two circuit elements of the same type are simultaneously attracted to the suction means, conveyed, and mounted.

The present inventors have invented an apparatus and method for solving the above-mentioned drawbacks, and have
A patent application has been filed as No. 37018.

The basic configuration of the invention is as follows.

That is, a plurality of magazines storing a plurality of identical circuit elements stacked vertically are installed upright according to the number and positional relationship of the circuit elements to be mounted on the board, and the lower E is connected to each magazine. A slide mechanism consisting of a slide plate and a fixing plate with holes drilled in the same relationship position as the hole group of the bottom plate is installed on the underside of the bottom plate of the multi-magazine, which has a bottom plate with a bottom plate. The fixing plate is made to be slidable between the plates, and the fixing plate is fixed by shifting the position of the fixing plate horizontally from the position of the bottom plate. move the slide plate from the position where the width of the waist plate matches the width of the bottom plate to the position where the width of the fixed plate matches the width of the bottom plate, and simultaneously remove the circuit elements in each magazine of the multi-magazine one by one. After transferring from the stationary plate to the recess of the pallet, lower the pallet and release it from the slide mechanism.
While maintaining the relative positions of each circuit element, or after further correcting the relative positions, the circuit elements are picked up by suction means and transported and mounted on the substrate.

When using the apparatus and method of the invention, circuit elements can be automatically mounted on a board smoothly.

However, with this method, 40 to 50
When transferring small and lightweight circuit elements from a multi-magazine to a pallet using a slide mechanism, the circuit elements may This is a fatal flaw of this method, as it tends to get stuck in the hole and cause clogging.

Although it is possible to avoid this by improving the accuracy of the dimensions of the outer diameter of the circuit elements and the sliding mechanism, it is technically extremely difficult, and even if possible, it would require a lot of effort, money, and time. That will happen.

The method of transporting a large number of small pieces using a slide mechanism has similar problems not only in the case of transporting circuit elements as described above, but also in many other cases.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for simultaneously transporting a large number of small pieces using a slide mechanism, which can solve the problem of small pieces getting stuck in the holes of the slide mechanism and can be carried out smoothly and automatically.

The method for simultaneously transferring multiple small pieces using the slide mechanism of the present invention is a multi-magazine system in which a large number of magazines for vertically stacking and accommodating a plurality of small pieces are installed, and a bottom plate is provided on the bottom side with a hole that communicates with each magazine. A slide mechanism consisting of a slide plate and a fixing plate with holes drilled in the same position relative to each other as the holes in the bottom plate on the underside of the bottom plate, the slide plate being sandwiched between the bottom plate and the fixing plate to make it slidable and fixed. Shift the worship position of the board horizontally from the worship position of the bottom plate and fix it.
Installation, move the slide plate from the position where the waist plate worship matches the bottom plate worship to the position where the fixed plate worship matches,
In a method of simultaneously transferring the small pieces in each magazine of a multi-magazine one by one from the position of the fixed plate to the next process, the sliding plate is held at a position where the position of the sliding plate coincides with the position of the fixed plate. This method is characterized by moving the objects to a position where they partially overlap.

Hereinafter, the method of the present invention will be explained based on drawings of embodiments.

In the embodiment, the small pieces are used as circuit elements.

First, as an example of a hybrid integrated circuit assembled by the method of the present invention, an example of an electronic tuner is shown in FIG.

A large number of rectangular circuit elements 2 are mounted and fixed on the substrate 1 in a perpendicular arrangement to the substrate 1.

More than 40 circuit elements 2 are mounted on the electronic tuner board 1 of FIG. 1, and the method of the present invention is particularly effective when transferring a large number of 40 to 50 circuit elements at the same time. However, in the drawings of the embodiments of the apparatus for carrying out the method of the present invention, in order to avoid the drawings from becoming complicated and unclear, drawings of the apparatus for transporting and mounting a large number of circuit elements in parts are shown below. The explanation will be based on.

FIG. 2 is a vertical sectional view of an embodiment of the apparatus for carrying out the method of the present invention, FIG. 3 is an enlarged view of the main part in FIG. 2, and FIG.
FIG. 5 is a perspective view of the illustrated portion, and is a partial cross-sectional view showing the state of movement of the slide plate.

FIG. 2 shows the multi-magazine 20, slide mechanism 30, and pallet 40.

21 is a magazine.

Each magazine 21 stores a large number (approximately 200 in one embodiment) of circuit elements 2 in a vertically stacked manner.

The multi-magazine 20 includes a large number of magazines 21. For example, in order to assemble the electronic tuner shown in FIG.
Magazines 21 are arranged upright.

(As mentioned above, the number of magazines is omitted.

) The multi-magazine 20 includes a pair of magazine plates 25 held by struts 24, and the magazine plates 25 hold and fix the magazine 21.

A weight 22 is placed on the circuit element 2, and a light downward load is applied to the circuit element 2.

Attached to the underside of the multi-magazine 20 is a bottom plate 23 having a hole 23A communicating with each magazine 21.

The slide mechanism 30 consists of a slide plate 31 and a fixed plate 32, each having holes 31A and 32A formed therein at the same positions relative to the holes 23A of the bottom plate 23.

The fixed plate 32 moves the position of the prayer 32A to the position of the prayer 2 of the bottom plate 23.
It is fixed to the fixed plate 32 at a position shifted from the position 3A, and the slide plate 31 is sandwiched between the bottom plate 23 and the fixed plate 32 and is slidable.

In Fig. 2, a pallet 40 having a recess 40A corresponding to the recess 32A of the fixed plate for the next process is placed on the lower side of the slide mechanism 30, and the pallet 40 is brought into contact with the fixed plate with the recess 40A and the recess 32A aligned. It is.

The apparatus of the embodiment is constructed as described above.

In the method of the embodiment, the slide plate 31 is moved from the position where the cedar plate 31's curvature 31A coincides with the bottom plate 23's cursor 23A to the position where the fixed plate 32's cursor 32A coincides (the distance is indicated by 9).

) Move in the direction of arrow 7 to the position where prayers 31A and 32A overlap.

FIG. 5 shows how the relative positions of each plate change.

When the prayer 31A of the slide plate 31 is made to match the prayer 23A of the bottom plate 23, the circuit elements 2 are lowered by their own weight and the load of the hanging bell 22, and are stopped by the fixed plate 32, one circuit element each in the hole group 31A. 2 enters.

This state is shown at the left end of FIG. Slide plate 31
When the circuit elements 2 are moved in the direction 7, two lengths of each circuit element are removed from each hole group 31A, and the other stacked circuit elements 2 are stopped from falling by the slide plate 31.

A guide plate or the like may be provided to facilitate extraction of the circuit element 2 and prevent damage.

A state in which the slide plate 31 is slid in the direction 7 and the prayer 31A matches the prayer 32A of the fixed plate 32 is shown in the center of FIG.

Even if the openings 31A and 32A are matched, if the outer diameter of the circuit element 2 or the machining accuracy of the openings 31A and 32A are not sufficient, the circuit element 2 will get caught and not fall as shown in the figure.

This is mainly due to the poor machining accuracy of the holes.
This is because the individual holes with A do not match perfectly.

When the slide plate 31 is moved in the direction of 7, it passes through a point where the individual holes completely coincide with each other, so the circuit element 2 falls from the base 32A of the fixed plate 32, and the circuit element 2 is carried to a pallet or the like. It will be done.

The slide plate 31 is moved in eight directions and returns to its original position.

The sliding direction of the slide plate 31, that is, the movement 32 of the fixed plate 32
The direction in which A is shifted with respect to the direction 23Al of the bottom plate 23 is selected to be a right angle direction or a 45 degree inclined direction, which corresponds to the arrangement of the rectangular circuit elements 2 arranged orthogonally.

When using the method of the present invention, it is possible to solve the problem of parts getting stuck due to machining dimensional accuracy, etc. when transporting small lightweight parts at multiple points simultaneously using the slide mechanism. The reliability and reliability of transfer can be improved.
