Semiconductor porcelain plate sand blasting machine

Abstract

The invention provides a semiconductor porcelain plate sand blasting machine, and relates to the field of semiconductor processing equipment. According to the semiconductor porcelain plate sand blasting machine, a plurality of spraying guns (2) are arranged on the inner side wall on the upper end of a rack (1), the orientations of the plurality of the spraying guns (2) are the same, a rotation disk (3) is arranged inside the rack (1) and is arranged on the orientation position of the plurality of the spraying guns (2), the rack (1) is provided with a dustproof cover (4) for preventing mortar splashing, the lower end of the dustproof cover (4) is provided with a spraying gun switch (5), and a sound absorbing material layer (6) is arranged on the inner side wall of the dustproof cover (4) and is mineral slag cotton. With the semiconductor porcelain plate sand blasting machine, the defects in the prior art can be overcome; and the sound absorbing material layer is additionally arranged on the inner side of the dustproof cover so as to absorb noise produced by the plurality of the spraying guns during simultaneous working, solve the problem of easy tinnitus and deafness generation due to long time work under high decibel noise of workers, and create a good working environment for operators.

Description

Technical field: [0001] The invention relates to a semiconductor processing device, in particular to a sandblasting machine for semiconductor porcelain plates. Background technique: [0002] In the process of semiconductor processing, it is necessary to spray a layer of mortar on the upper porcelain plate. In the prior art, manual sandblasting is mainly used. The operator holds the spray gun to perform sandblasting, and sprays back and forth in different directions. It takes a long time , will bring a large amount of labor to the operator, making the operator feel very tired. [0003] Patent No. 200820221105.X discloses a sandblasting machine, which includes a sandblasting frame and a spray gun. Several spray guns facing in common are fixed at different positions above the sandblasting frame, and a fixed turntable is also arranged at the direction of the spray gun. There is also a dust cover on the shelf. Such a sandblasting machine has the advantages of convenient operatio...
