Abstract

PURPOSE:To make plurally paired guide covers adjustable speedily, easily and accurately with single operation, by guiding a coupled body, interconnecting each pair of these plurally paired guide covers being symmetrically opposed, in a horizontal direction at a right angle to a conveying direction. CONSTITUTION:Each of adjusting rods 5 and 6 having branchlike arms 5a-5c and 6a-6c is supported by bearings 5d and 6d free of slide motion in an orthogonal direction to chute rails 2a-2c. And, each of guide bars 3a-3b and 4a-4c is attached to each of these arms 5a-5c and 6a-6c, constituting each of side cover coupled bodies at both sides, and they are made free of slide motion by these bearings 5d and 6d. When width size W of a conveyed work is varied, these rods 5 and 6 are adjusted to the direction of arrows L-R and L'-R' whereby each clearance between packages 1a-1c and these guide covers 3a-3c and 4a-4c is made proper, thus all lanes A-C are adjustable as much as the same extent simultaneously.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a guide cover provided on a thin IC chute, and more particularly to a guide cover provided with an adjusting device for chute rails installed in parallel in multiple rows. It is related to.

[Background of the invention]

FIG. 2 is a perspective view showing the thin ICI placed on the chute rail 2.

A thin IC is a flat type IC with parallel top and bottom surfaces, and a large number of leads protruding from the sides parallel to the plate surface.
It is defined as C and is rapidly becoming popular because it can be mounted at high density in a narrow space.

In FIG. 2, 18 is a flat package, and 1b is a lead. Figure 3 shows a thin IC using the chute rail 2.
It is a sectional view of a state in which I is being transported.

A pair of guide covers (left) 3 and guide cover (right) 4 are installed to cover the thin IC 1 so that the thin IC 1 slides smoothly along the chute rail 2 and does not fall.

When the width dimension W of the thin ICI that is the transported object changes,
The chute rail 2 has a large tolerance for changes in the width dimension W, but the distance between the pair of guide covers (left) 3 and (right) 4 is precisely adjusted according to the change in the width dimension W, and the package 1a If you do not maintain proper clearance between them, smooth and reliable transportation cannot be expected. For this reason, the pair of guide covers (left) 3. Same (right) 4 is the adjustment means (
(not shown) to make adjustments in parallel in the left and right directions as shown by arrows L-R and L'-R'.

On the other hand, with the improvement of IC production technology and production efficiency, multiple rows of chute lanes (A), as shown in Figure 4,
(B) and (C) are now installed. 2a, 2b, and 2c shown in this figure are chute rails, la
, lb, and lc are thin ICs that are objects to be transported. Left and right guide covers 3a, 4a, 3b, 4 are provided to guide the thin ICs 1a, lb, lc mentioned above.
b, 3c.

4c is provided. Since it is necessary to provide means for individually adjusting these three pairs of guide covers as shown by arrows L-H, the structure of the adjusting means becomes complicated, and the adjustment requires a great deal of effort and time.

[Purpose of the invention]

The present invention has been made in view of the above circumstances.

It is an object of the present invention to provide a guide cover that allows a plurality of pairs of guide covers provided on a plurality of rows of chute rails to be quickly, easily, and precisely adjusted by a single operation.

[Summary of the invention]

In order to achieve the above object, the guide cover of the present invention provides a guide cover for thin ICs transported on each chute rail in a thin IC chute in which a plurality of chute rails are installed in parallel.
A pair of guide covers facing left and right in the direction of travel are provided for each of the plurality of pairs of guide covers, and among the plurality of pairs of guide covers, the guide covers on the left side in the direction of travel are interconnected, and the guide covers on the right side in the direction of travel are connected to each other. A pair of guide cover connectors are interconnected to form a pair of guide cover connectors, and the guide cover connectors are provided with means for guiding each of the pair of guide cover connectors in a horizontal direction perpendicular to the conveying direction, and a means for driving the guide cover connectors. .

[Embodiments of the invention]

Next, one embodiment of the present invention will be described with reference to FIG. 1. This embodiment is an example of improving the three chute rail devices according to the prior art shown in FIG. 4 by applying the present invention. Chute rails 2a, 2b, 2c, guide cover (left) 3a with the same drawing reference numbers as in Figure 4
, 3b, 3c, guide cover (right) 4a, 4b,
Reference numeral 4c designates the same or similar structural members to those in the conventional example (FIG. 4).

This embodiment includes an adjustment rod 5 having branch-like arms 5a, 5b, and 5c, and branch-like arms 6a, 6b, and 6c.
and an adjustment rod 6 having a bearing 5d, respectively.
6d, it is slidably supported in a direction perpendicular to the chute rail (without intersecting it).

Guide covers (left) 3a, 3b, and 3c are attached to arms 5a, 5b, and 5c of adjustment rod 5, respectively, to form a guide cover (left) connection body. Similarly, guide covers (right) 4a, 4b, and 4c are attached to arms 6a, 6b, and 6c of adjustment rod 6, respectively, to form a guide cover (right) connection body. The (left) and (right) guide cover connectors are supported by bearings 5d and 6d, respectively, so as to be slidable in the left-right direction in the figure (in the direction of arrows LR and L'-R').

In the guide cover configured as described above, when the width dimension W of the thin IC to be transported changes, the adjustment rods 5 and 6 are adjusted in the force directions of the arrows L-R and L'-R'. I
The clearance between the C package and the guide cover can be adjusted appropriately, and this adjustment operation can be performed on all lanes (A),
(B) and (C) can be performed simultaneously and in the same amount.

These functions have been made possible by changing the thin IC model.
It is clear that the effect is exhibited when the It has the most practical effect in fine-tuning the case.

〔Effect of the invention〕

As detailed above, the guide cover of the present invention allows the clearance dimensions of multiple pairs of guide rails provided in multiple rows of chute rails to be quickly, easily, and accurately adjusted by a single operation. It has such practical effects and greatly contributes to improving productivity in the IC industry.
