Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a drilling machine for flexible printed circuit boards (hereinafter simply referred to as flexible circuit boards), and in particular, the present invention relates to a drilling machine for drilling flexible printed circuit boards (hereinafter simply referred to as flexible circuit boards), and in particular, for shortening flexible circuit boards wound into rolls. This invention relates to a drilling machine for flexible substrates that is capable of drilling holes without cutting them.

[Prior art]

For example, as a drilling machine for printed circuit boards,
This is a drilling machine disclosed in No. 8007.

In this drilling machine, a printed circuit board that has been cut to the required size is stacked with backing plates on top and bottom, and a reference pin is press-fitted and fixed together, which is then placed and fixed on a table. After relatively moving the drill supported by the cross slide to perform positioning in the X-Y directions, the drill is moved in two directions to drill holes.

When drilling a hole in a flexible substrate, it is necessary to cut the flexible substrate to a required size, place a patch plate on top and bottom of the flexible substrate, and press-fit a reference pin to fix the cut pieces together.

[Problem that the invention seeks to solve]

For this purpose, we cut the flexible substrates supplied in rolls to the required size, stacked several sheets, placed a patch plate on top and bottom, and temporarily fixed the edges with adhesive tape. Drill a hole, insert the reference pin into and out of this hole,
Preparation work is required to remove the adhesive tape from the periphery, and after drilling, post-processing is required to remove the reference pin and remove the backing plate.

All of these operations are done manually, and since the flexible substrate is flexible, the workability is poor. In addition, since the flexible substrate is cut into short lengths in the subsequent processing step of drilling, there are problems such as difficulty in automation.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to provide a flexible substrate drilling machine that can cut a rolled flexible substrate into short pieces and directly punch holes therein.

[Means for Solving the Problems] Means of the present invention for achieving the above object will be explained based on FIGS. 1 and 2, which correspond to embodiments.

The flexible substrate is fixed on the table 34 together with the plate.

Reference numeral C denotes a drilling device, which includes a slider 50 that moves in a plane parallel to the mounting surface of the table 34, and a nozzing 52 that is supported by the slider 50 so as to be slidable in the vertical direction. Place the spindle so that it can rotate,
This spindle holds the tool.

D is a supply/discharge device, which includes a table 34 and a flexible substrate 10.
A lower plate supply/discharge device D1 that supplies the lower plate 61 between them, and an upper plate supply means D2 that supplies the upper plate 79 onto the flexible substrate 1.
Consists of.

The lower plate supply/discharge device D1 includes a magazine 59 for storing unused lower plates 61, a tray 64 for storing used lower plates 61, and a carrier 70 for transporting the lower plates 61.

Similarly, the top plate supply/discharge device D2 includes a magazine 77 for storing unused top plates 79, a tray 80 for storing used top plates 79, and a carrier 86 for transporting the top plate 78.

[For production]

When the drilling is completed, the work holder 35 rotates to release the upper plate 79, the flexible substrate 1, and the lower plate 61. Then, the carrier 86 moves and transfers the upper plate 79 on the flexible substrate l to the tray 80. Next, when the table 34 descends, the carrier 70 moves and transfers the lower plate 61 on the table 34 to the tray 64.

Then, the winding means A2 is activated to remove the flexible substrate l.
Pull out a predetermined amount and wind it up. Then, the carrier 70 moves, takes out the lower plate 61 from the magazine 59, and places it on the table 3.
4.Feed on top. Next, the table 34 is raised and brought into contact with the lower surface of the lower plate 61t--the flexible substrate 1. Then, the carrier 86 moves, takes out the upper plate 79 from the magazine 77, and supplies it onto the flexible substrate l. Then, the work holder 35 rotates and lowers onto the table 34.
61. When the flexible base MLl and the upper plate 79 are fixed, the hole puncher 1ttc is activated to make a hole.

In this way, it is possible to make holes without cutting the flexible substrate 1 into short lengths.
