Description

Technical Field

[0001] The utility model relates to the technical field of target material production, in particular to a sandblasting device for square target materials. Background Art

[0002] The target material is the target material bombarded by high-speed energetic particles. When used in high-energy laser weapons, lasers of different power densities, different output waveforms, and different wavelengths interact with different target materials, different killing and destructive effects will be produced.

[0003] In the sputtering process, the target assembly, as the cathode, should first have excellent electrical conductivity. At the same time, in order to discharge the heat generated by high-energy ions bombarding the target surface at high speed, the target assembly should also have excellent thermal conductivity. Therefore, the target needs to be fixedly connected to the back plate with welding material indium to avoid the sputtering target from falling off and cracking during operation. In order to ensure the welding rate of the target and the back plate, the back side of the target (non-sputtering surface) needs to be roughened to better adhere to the welding material indium. However, in the welding process, the welding material indium is easy to overflow from the edges around the target and the back plate. The welding material needs to be removed, and the roughness of the removal area and the surrounding area of ​​the target needs to be increased. In the sputtering process, this area after roughening can better adhere to the target material deposited there, reducing the probability of its overflow. The roughening of the back and surrounding of the target and the removal of indium from the welding material all require sandblasting. The sandblasting process uses the impact of a high-speed sand flow to clean and roughen the solid surface. Currently, the sandblasting process is mainly performed manually, which has the disadvantages of dust pollution and heavy workload. Based on this, the present application proposes a sandblasting device for square targets, which can solve the above problems. Utility Model Content
