Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, specifically a fixed-length cutting device for copper foil processing. Background Technology

[0002] Copper foil is a cathodic electrolytic material, a thin, continuous metal foil deposited on the substrate layer of a circuit board, serving as the conductor in the PCB. It easily adheres to the insulating layer, receives the printed protective layer, and forms the circuit pattern after etching. During copper foil processing, the unwound copper foil strip needs to be cut. However, existing cutting equipment is not convenient for cutting to a fixed length during operation, easily leading to variations in the length of the cut copper foil. Furthermore, the cutting blade is a wear part that requires periodic sharpening during prolonged copper foil cutting, but the inconvenience of disassembling the cutting blade affects the normal operation of the equipment. Therefore, improvements to the existing technology are needed. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model adds a frame, eccentric wheel and transmission shaft to the equipment plate. During use, the motor drives the conveyor roller to rotate, which in turn drives the eccentric wheel to rotate. The eccentric wheel drives the drive plate to move back and forth through the pull rod and other structures, which in turn drives the cutting blade to move up and down back and forth, so as to cut the copper foil to a fixed length.
