Technical Field

[0001] The utility model relates to the technical field of lens processing devices, in particular to a sandblasting machine capable of automatically flipping and sandblasting. Background Art

[0002] Sandblasting is a process that uses the impact of high-speed sand flow to clean and roughen the surface of the substrate. It uses compressed air as the power to form a high-speed jet beam to spray the material at high speed onto the surface of the workpiece to be processed, so that the appearance or shape of the outer surface of the workpiece changes. Due to the impact and cutting action of the abrasive on the workpiece surface, the surface of the workpiece acquires a certain degree of cleanliness and different degrees of roughness. Sandblasting machines are needed for deep processing in the production and processing of lenses.

[0003] The sandblasting machine in the prior art (such as the patent with publication number CN217345077U) places the lens on a placement seat when sandblasting the lens.
