Description

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

[Conventional technology]

Conventionally, as a method of cutting a printed wiring board used for manufacturing a printed wiring board, the printed wiring board is moved in the horizontal direction while the fixed cutting section is used to cut the board in the horizontal direction. The cutting in the direction is simultaneously performed by the cutting unit movable in the vertical direction.

[Problems to be solved by the invention]

However, according to the above method, the fixed cutting portion performs the lateral cutting in association with the lateral movement of the printed wiring board, and the longitudinal cutting is movable during the lateral cutting process. Since this is performed while moving the parts in the vertical direction, it is necessary to temporarily stop the horizontal movement of the printed wiring board at the time of cutting in the vertical direction. It is necessary to systematically control the operations of moving the vertical cutting section, returning to the original position, and stopping.

Therefore, the need for each of these related operations also 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 loses this balance will rotate without load, it is possible to remove "burn, chip, burr, burr," on both sides of the horizontal cut 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.

Therefore, the present invention was developed in view of the drawbacks of the conventional method for cutting a printed wiring board, and it is
An object of the present invention is to provide a cutting device for a printed wiring board which can prevent chipping, burrs or other damages and which is easy and quick in operation.
