Technical Field

The invention relates to a winding and cutting mechanism of a diaphragm for a copper-clad plate.

Background

A Copper Clad Laminate (CCL) is a plate-like material, which is simply called a Copper Clad Laminate, prepared by impregnating electronic glass fiber cloth or other reinforcing materials with resin, coating Copper foil on one or both surfaces, and performing hot pressing. The copper-clad plate often needs to be attached or protected by a membrane in subsequent processing such as etching, protection, cutting and the like. In the process of using the film, a large roll of film is often required to be separated into a plurality of small rolls of film. In the winding process, after a small roll is wound and unloaded, another reel is mounted to perform the winding operation of the next small roll, which tends to result in low winding efficiency.

For example, when the winding and cutting mechanism for the film for copper clad laminate is used, the first cylinder 31 drives the first winding roller 32 to rotate so as to wind the film 100. After the first winding roller 32 finishes winding and cutting, the second winding roller 42 winds the film sheet 100. After that, the first winding roller 32 and the film 100 thereon can be unloaded and subsequently operated, so that the unloading time can be saved and the winding efficiency can be improved.

The two rotary cylinders 53 of the tightening assembly 70 are made of metal material and are aligned with the two pin areas, respectively. After the diaphragm 100 on the first winding roller 32 is cut, the two rotating cylinders 53 of the abutting assembly 70 are used for abutting the end part of the diaphragm 100 to move to the second winding roller 42, so that the end part of the diaphragm 100 is forced to be sleeved on the plurality of positioning short needles in the two needle inserting areas, and the plurality of positioning short needles are used for puncturing and fixing the end part of the diaphragm 100. The two rotary drums 53 are further configured to press the positioning short pins to descend so as to partially enter the second winding roller 42, and the second winding roller 42 is configured to drive the film 100 to rotate through the positioning short pins so as to wind the film into a second film roll. The two rotary cylinders 53 of the tightening assembly 70 are further used for tightening the second film roll wound on the second winding roller 42 to tension the film 100 wound on the second winding roller 42. By providing the plurality of positioning short needles, it is possible to facilitate the insertion of the needles and to fix the end of the membrane 100.

The two elastic pull ropes 84 are respectively connected to two opposite sides of the sliding knife rest 82, and one ends of the two elastic pull ropes 84 far away from the sliding knife rest 82 are respectively connected to two opposite ends of the cross bar 52. The elastic pull cords 84 are located on opposite sides of the membrane 100.
