Description

Lamination and cutting structure

This invention relates to a laminating and cutting structure, especially one that can effectively increase the speed of laminating processing.

In the manufacturing process of printed circuit boards, before the substrate is exposed, a photoresist layer and a film adhered to the surface of the photoresist layer are formed on the upper and lower surfaces of the substrate, and after exposure, the film is peeled off to make the photoresist Layers are exposed for subsequent development and etching procedures. Generally, the thickness of the substrate for lamination is about 20 μm-25 μm. During the lamination process, if the temperature of the substrate is too high or too low, it will affect the quality of the lamination. Therefore, the current working temperature of the lamination must be Maintain it at around 50°C to achieve the best lamination quality. However, since the preheating equipment of the traditional film laminating machine is mostly installed at the front end of the conveying equipment, and the preheating equipment is far away from the film lamination processing place, after the substrate passes through the preheating equipment, it is often caused by the rapid heat dissipation of the substrate on the way of transportation. When entering the hot press mechanism, the working temperature is too low, resulting in poor film quality. If the preheating temperature is increased, it is easy to cause wrinkling of the thin plate after film lamination.

In order to improve the above problems, as shown in the TW M252545 "laminating machine and its heating mechanism" patent case, a solution is provided. The laminating machine includes a hot pressing wheel device, a conveying mechanism and a heat transfer mechanism.

In order to control the working temperature of the sheet at about 50°C by using the heating program provided by the thermal transfer mechanism before the sheet being processed enters the lamination process by the conveying mechanism, so as to provide the best lamination quality of the sheet.

With the structure of the above lamination machine, better lamination quality can indeed be achieved. However, the conventional configuration of leveling suction cup, cutter seat and film laminating seat can only achieve a processing speed of about 2.5 m/min in the actual film lamination operation of the film laminating machine, and there is still room for improvement.
