Description

Technical Field

[0001] The utility model belongs to the technical field of circuit board forming and preparation, and in particular relates to a copper foil cutting device for cutting circuit boards. Background Art

[0002] Patent application number 202223230987.5 discloses a copper foil cutting device for cutting circuit boards, including a device support, a device cutting seat, a cutting support, a blade and a polishing disk, etc. Through the cutting station, the polishing station and the cutting positioning support, the cutting operation can be better carried out, the position of the copper foil can be quickly positioned, the cutting stability performance is excellent, the polishing operation of the cut copper foil is convenient, the operation is easy, and the effect of use is better than the traditional method.

[0003] However, the above copper foil processing still has the defect of inconvenient operation: first, cutting the copper foil and removing the burrs of the copper foil are two independent processes. It is necessary to drive the blade to cut the copper foil first, remove the blade after cutting, and then move the polishing disc to the cutting position to remove the burrs. The repeated movement process makes the processing steps more complicated and inconvenient for copper foil processing. Secondly, the copper chips generated by polishing will enter the cutting groove. If the copper chips in the cutting groove are not cleaned, it will affect the subsequent normal cutting of the copper foil by the blade. If the cutting groove is cleaned, the operation steps will increase, further causing inconvenience in operation. Utility Model Content
