The production of ceramics has very strict requirements. At the same time, the processing of ceramics is also very important, especially the carving of ceramics.

[0003] At present, a laser engraving machine with a clamping device has certain defects, such as a ceramic engraving machine proposed in patent application number "CN202221571527.6". The device arranges a buffer plate between the clamping devices on both sides, and clamps the ceramic product twice on the left and right by pushing the buffer pad in the middle of the buffer plate. While clamping and fixing, it avoids damage to the ceramic product caused by excessive force. However, in actual use, after engraving the ceramic product, a large amount of waste chips will remain on the end surface of the processing table. These waste chips will adhere to the processing table of the engraving machine or the ceramic product. If they are not cleaned in time, they will affect the engraving accuracy in the subsequent laser engraving process. Utility Model Content
