Description

Description: TECHNICAL FIELD The present invention relates to a cutting device for cutting a printed wiring board (copper clad laminate) used for manufacturing a printed wiring board into a required size.

[Prior Art] Conventionally, as a method of cutting a printed wiring board used for manufacturing a printed wiring board, a horizontal cutting is performed at a fixed cutting portion while moving the printed wiring board in the lateral direction, and During the cutting process, the cutting in the vertical direction is simultaneously performed by the cutting unit movable in the horizontal direction.

A "trimming / cutting device" using a plate-shaped wood as a material to be cut is disclosed in Japanese Patent Publication No. 54-555 and a printed circuit board, etc. A device for dividing "is disclosed in JP-A-56-27799.

The former makes it possible to trim and cut a plate-shaped wood while vertically and horizontally grinding it with a plurality of circular sawing units for vertical grinding, and the latter can cut a laminated plate with a plate hammer shear. It was done like this.

[Problems to be Solved by the Invention] However, according to the former device, the horizontal cutting is performed by the fixed cutting portion in association with the horizontal movement of the printed wiring board. During the cutting process, the vertical cutting is performed while moving the movable cutting unit in the vertical direction. Therefore, during the vertical cutting, the horizontal movement of the printed wiring board is temporarily performed. In this case, it is necessary to forcefully stop the operation, and to properly control the operation system for returning and stopping the vertical cutting portion to the movement source position related thereto.

Therefore, the need for each of these associated operations results in reduced work efficiency.

Further, in the case of cutting the printed wiring board in the longitudinal direction, if the printed wiring board is forcibly stopped, the cutting force of each cutting blade is suddenly lost and the balance of the rotating cutting blade is disturbed. Since each cutting blade that breaks this balance will rotate without load, "burn, chip, burr, and burr on both sides of the horizontal cutting edge of the printed wiring board that is stopped.
This is a factor that causes "other scratches" and blurring of each cutting blade in subsequent cutting.

That is, since the former device does not use the “printed wiring original plate” as a material to be cut, the above-mentioned drawbacks occur when it is applied directly to the cutting of the printed wiring original plate.

Further, in the case of the latter device, it is possible to solve the drawbacks of the above device.
It is not possible to prevent the occurrence of "chips", and in terms of work efficiency, unless a plurality of circular saws are returned to their original positions each time, the next order of cutting cannot be started, resulting in a decrease in efficiency. .

Therefore, the present invention has been developed in view of the drawbacks of the conventional cutting device for a printed wiring board, and it is possible to prevent burns, chips, burrs or other damages that occur at the cut end, and to simplify and speed the work. The purpose of the present invention is to provide a cutting device for a printed wiring board that is highly versatile.
