Description

Technical Field

[0001] The utility model relates to the technical field of PCB substrate production, in particular to a punching type PCB substrate cutting machine. Background Art

[0002] The substrate is the basic material for manufacturing PCB. Generally speaking, the substrate is a copper-clad laminate. In the manufacturing of single-sided and double-sided printed boards, hole processing, chemical copper plating, electroplating copper, etching and other processing are selectively performed on the substrate material - copper-clad laminate to obtain the required circuit pattern. The manufacturing of another type of multi-layer printed circuit board also uses the inner core thin copper-clad laminate as the base, and alternately laminates the conductive pattern layer and the prepreg together through one-time lamination to form more than 3 layers of conductive pattern layer interconnection.

[0003] PCB substrates often need to be stamped and cut during production. A Chinese patent discloses a stamping FPC substrate cutting machine (authorization announcement number CN113939090A). The patented technology can drive the rotating shaft to rotate through the first motor, and the rotating shaft drives the first telescopic rod to rotate, and the first telescopic rod drives the pulley assembly to revolve. The position of each pulley assembly can be adjusted by extending and shortening the first telescopic rod, thereby changing the contour motion trajectory of the drive belt, so that substrates of different shapes and sizes can be cut.

[0004] Although this solution can achieve the advantage of punching and cutting substrates of different sizes in actual use, it is inconvenient to fix them in actual use, which leads to reduced cutting accuracy and cannot meet actual use needs.

[0005] In order to solve the above problems, we have made improvements and proposed a cutting machine for stamping PCB substrates. Utility Model Content
