2. Description of the Related Art Conventionally, when a module or a printed circuit board loaded with electronic components is mounted on an electronic device, these modules and the like (hereinafter also referred to as works) are manufactured in advance in each manufacturing department. Especially when the work is plate-shaped, each is laminated before mounting, and
The stacked work is supplied, for example, in the upward direction by a drive mechanism, and when the supplied uppermost work comes into contact with the upper stopper, the work is separated from other stacked works, that is, the uppermost work is separated. 2. Description of the Related Art A method and an apparatus are known in which a workpiece is transferred by, for example, a lateral direction by means of an opposite-direction driving unit.

An apparatus shown in FIG. 8 is a plate-like member (plate-like work) supply apparatus which has been conventionally used by the present applicant.
Plate-like works are stacked, and the stacked works are supplied in one direction by one-way driving means, and the supplied state-of-the-art work is transferred in the other direction.

That is, the air cylinder 2 serving as the one-way driving means feeds the plate-like members 1 and 1 upward by air sent from an air pump (not shown), and the uppermost plate-like member 1a is brought into contact with the plate. 3, the air cylinder 4, which is the other direction going drive means, is driven (FIG. 9), and the slider 5 forcibly moves the stacked plate members 1 a from the other plate members 1, 1. (FIG. 10 and FIG. 11). When the slider 5 returns to the initial position, the plate members 1 and 1 below the plate member 1b are immediately lifted by the air cylinder 2 which is constantly operating, and the next plate member 1b is moved to the contact plate. 3 (Fig. 1
2) The plate-like member 1b is forcibly separated from the other plate-like members 1 and 1 by the slider 5, and thereafter, similarly, the uppermost plate-like member is sequentially cut out. In the drawing, reference numeral 6 denotes an upstream stage, 7 denotes a downstream stage, and 8 and 8 denote supporting profiles for fixing the plate 3, the stages 6, 7 and the like to an apparatus frame (not shown). belongs to.

According to such a conventional supply method and apparatus, the use of the air cylinders 2 and 4 enables reliable separation and supply of plate members at a relatively low price. Was.

[0006]

However, according to the above-mentioned conventional supply method and apparatus, even if the pressing force above the air cylinder 2 is made as small as possible, the surface of the plate-shaped member is hardened by a mold resin or the like. In the case of the lower one, it was found that scratches occurred on the front and back of the member at the stage where the uppermost plate-like member was sequentially cut out.

This is because, in the conventional apparatus, the uppermost plate-like member is pushed out while the plate-like members 1 and 1 are constantly pressed upward by the air cylinder 2. Then, a scratch due to the contact plate 3 and a scratch due to the member and the slider 5 occur. As shown in FIG. 10, immediately before the rear part of the plate-like member 1a comes off, the plate-like member 1b immediately below presses the top-most plate-like member 1a. It has been found that the load concentrates on the rear part of the member 1a and the front part of the plate-like member 1b, and scratches easily occur on the front and back of the member.

Therefore, the present invention proposes a method and an apparatus for supplying a plate-like member capable of avoiding the occurrence of scratches on the front and back of the member by improving the conventional supply method and the apparatus therefor. Is what you do.
