Description

Technical Field

It is a plate-shaped material made by impregnating the reinforcing material with resin, covering one or both sides with copper foil, and hot pressing.

[0003] The existing copper clad laminate pressing device clamps the copper plate through the interaction of structures such as motors and threaded rods, and places the copper plate on the plate, while the push plate squeezes the copper plate and the plate to save manpower. This device lacks effective limiting means during the feeding process, and cannot ensure the stability of the shape, posture and position of the plate and the copper plate, and thus cannot ensure that the two are aligned and fitted when stacked, resulting in poor quality of the finished product obtained by pressing. At the same time, when feeding, it is necessary to wait until the extrusion is completed before loading, which leads to a long processing cycle and affects the processing efficiency. At the same time, there are hidden dangers to the safety of the staff's hands during the feeding operation on the machine. The existing copper clad laminate pressing device directly squeezes the product.
