Description

Stepping device of multi-directional numerical control method {STEP PRESSING APPARATUS USING NUMERICAL CONTROL OF X-Y MULTI DIRECTION}

The present invention relates to a punching device, and more particularly, to continuously supply a product such as a coverlay film in a roll-to-roll type to perform a continuous punching operation by moving a mold in a XY multi-direction according to the size of the product. The present invention relates to a XY multi-directional numerical control method that can be precisely punched without changing molds or defective products according to the amount of expansion of the product.

In general, flexible printed circuit boards (FPCBs) cut copper foil laminated plates to meet specifications and form guide holes, print circuits on the surface of copper foil, and then corrode copper foil to form circuits, and coverlay film is attached to copper foil. It is then produced by a series of processes, such as pressing the coverlay film at a high temperature.

Then, the coverlay film is processed to expose the circuit portion by a punching operation and then attached to the disc, the punching operation is a sheet type (sheet type) for punching by fixing a sheet of cut film to a mold with a predetermined size; It is divided into a roll to roll type in which a film is wound on a reel and continuously punched and punched.

Here, the sheet method has a low work efficiency and a high defect rate of the product, whereas the roll-to-roll method continuously supplies the film by using a reel in which the coverlay film is wound, so that the punching operation is automated to improve the work efficiency and the product. The defective rate of can also be improved.

However, in the roll-to-roll method, the product is interposed between the upper mold and the lower mold, and a plurality of rows of punching holes are formed at the same time by one punching operation, so it is difficult to cope with the stretch amount of the coverlay film or the printed circuit board due to climate change. In order to produce a precise product, there is a problem in that the mold needs to be replaced.

In addition, in the roll-to-roll method, the product supplied into the punching mechanism is subjected to numerical control step shifting continuous punching operation of the mold in the Y direction, and the machining of precise dimensions is performed, but the numerical control step shifting continuous punching operation of the mold is not performed in the X direction. In addition, only the clamp of the transfer mechanism releases the rolled product and transfers it for a certain distance. Therefore, the transfer distance is not precise, so the precise punching work cannot be performed in the X direction, and the product must be transferred outside the punching range of the punching mechanism. In this case, there is a problem in that the mold needs to be replaced to process the size of the product out of the punching position.

The present invention has been made to solve the problems of the prior art as described above, by flexibly performing precise punching by fitting the product in various directions of XY through the numerical control correction operation of the position of the X-axis to Y-axis to which the press die is moved XY multi-directional numerical control method that can reduce the defect rate of products by eliminating mold replacement and precisely multi-directional punching work, as it can quickly reflect the amount of expansion and contraction of products due to climate change.
