Description

Technical Field

[0001] The utility model relates to the field of semiconductor liquid sandblasting, and more specifically, to a sandblasting angle adjusting structure for a semiconductor liquid sandblaster. Background Technique

[0002] Semiconductors refer to materials with electrical conductivity between conductors and insulators at room temperature. Sandblasting uses compressed air as power to form a high-speed jet beam to spray abrasive materials (copper ore sand, quartz sand, emery, iron sand, sea sand) onto the surface of the workpiece to be processed at high speed, causing changes in the appearance or shape of the workpiece surface. When semiconductors are refurbished, sandblasting is used to process the recycled semiconductors to facilitate reuse. In the document with the publication number CN216883410U, a nozzle angle adjusting device for a sandblaster is proposed. By controlling the sliding pin on the outer side of the movable connecting plate to slide inside the angle disc, the included angle between the movable connecting plate and the fixed connecting plate is controlled. When the rack through rod rotates, it will drive the ratchet to rotate. When the ratchet is adjusted unidirectionally, it will be prevented from rotating back under the limit of the limit pawl, so that the position of the nozzle can be adjusted. When the above nozzle angle adjusting device of the sandblaster is in use, the included angle between the movable connecting plate and the fixed connecting plate is controlled to adjust the spraying angle of the nozzle. However, as the angle becomes smaller, the movable connecting plate and the fixed connecting plate will clamp the sand injection pipe, resulting in a reduction in the sandblasting amount and affecting the sandblasting effect. Content of the Utility Model
