Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to thin plate materials roughly divided into rectangular or square shapes, such as end faces of rectangular plate materials for finishing printed circuit boards into rectangles or squares with accurate right angles. It is related to processing machines.

(Prior art) As a conventional technology, there is a structure shown in FIG.

That is, the cutter 3 is placed on the side of the reference table 2 that the end surface 1a of the work 1 made of a printed circuit board divided into rectangular parts comes into contact with, and when the end surface 1a of the work 1 moves along the reference table 2, the cutter 3
The structure was such that the end surface 1a was cut by the steps.

(Problems to be Solved by the Invention) In the conventional device described above, the cutter 3 is placed on the side of the reference table 2 that guides the end surface 1a of the work 1, so each end surface 1a to 1d of the work 1 is When the end faces 1a to 1d are processed with the cutter 3, the end faces 1a to 1d are processed smoothly with a predetermined precision, but the perpendicularity with the adjacent end faces is different from the original rough division. This resulted in the angle being maintained as it was, and a drawback was that high precision perpendicularity could not be expected.

The object of the present invention is to provide a novel end face processing machine for rectangular plate materials that eliminates the above-mentioned drawbacks.

(Means for Solving the Problems) In order to achieve the above object, the present invention is configured as follows.

The structure includes a lower operating mechanism that moves the upper suction tool downward, and a side operating mechanism that moves the upper suction tool downward, corresponding to the end surface of one of the upright sides of the workpiece, and a cutting device that moves vertically with respect to the table. It is something.

(Function) Since the present invention has the above-described configuration, when the workpiece is placed upright on the table and each clamping mechanism is activated, the lower side of the workpiece is abutted and supported along the table, and the lower side of the workpiece is supported. and one of the upright sides are held by the respective holding mechanisms and held upright with respect to the table.

If the cutter device is operated in this state, the end face of one of the upright sides of the workpiece will be cut on a vertical line, that is, perpendicular to the lower side.

In addition, when each clamping mechanism is released and the lower suction device is moved horizontally in the direction of the other upright side of the workpiece via the lower operation mechanism and the side operation mechanism, and the upper suction device is moved downward, the workpiece rotates, one of the upright sides that stood up in the previous process comes into contact with the table, and the upper side that was horizontal in the previous process also stands up and faces the cutter device.
