[0002] Etching is a technique that uses chemical reactions or physical impact to remove part of a material. Etching technology can be divided into two categories: wet etching and dry etching. It was first used to make printing embossed plates such as copper plates and zinc plates. It is also widely used to reduce the weight of instrument panels, nameplates, and thin workpieces that are difficult to process with traditional processing methods. After continuous improvement and development of process equipment, it can also be used for the processing of precision etching products of electronic thin-film parts in the aviation, machinery, and chemical industries. Especially in the semiconductor process, etching is an indispensable technology.

[0004] After using the etching tank, it was found that although the etching tank can be used for etching, it can only hold one piece at a time, and the efficiency is low.

[0013] Preferably, the movable frame does not contact the etching tank body, and the movable frame does not contact the spray pipe.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model rotates the second motor and the large gear, which causes the small gear to rotate around the large gear and perform revolution. At the same time, the small gear also rotates, and the clamping plate and the support rotate, so that both sides of the material to be etched can be etched.

Since the four first screw rods 201 rotate synchronously, the moving frame 3 remains horizontal when moving up and down. The material to be etched is fixed on the moving frame 3. The moving frame 3 is moved into the etching tank body 1 for etching. A second motor 301 is fixedly installed in the middle of the upper surface of the moving frame 3. The second motor 301 is waterproof to prevent the etching liquid from entering. A large gear 302 is fixedly installed on the output shaft of the second motor 301.
