Problems solved by technology

[0002] Single-side polishing machine is currently the main equipment for processing hard and brittle materials such as monocrystalline silicon, polycrystalline silicon, electronic grade silicon, and sapphire. When the upper polishing head is used for pressure, the pressure of the polishing head cylinder will cause the processing pressure of the equipment to fluctuate and be unstable. , and the pressure on the ceramic disc is uneven

Abstract

The invention discloses a polishing head structure of a polishing machine. The polishing head structure comprises a support, a vertical motor, a driving gear, a driven gear and an air cylinder assembly, wherein the vertical motor is fixed to the support; the driving gear is located in the support and fixedly connected with the output end of the vertical motor; the driven gear is fixedly connectedto an upper disc shaft assembly and is in engaged transmission with the driving gear; a cylinder rod of the air cylinder assembly is connected with a transition shaft sleeve assembly; an anti-rotationsleeve is arranged at the upper end of the transition shaft sleeve assembly; a rotary connector assembly is arranged in the anti-rotation sleeve and connected with the upper disc shaft assembly; theupper disc shaft assembly is rotationally arranged in the support; the lower end of the upper disc shaft assembly is connected with an upper disc assembly; the upper disc assembly is located below thesupport; and an organ cover is arranged between the support and the upper disc assembly and connected to the upper disc shaft assembly. According to the polishing head structure, a balancing weight adjusting and pressurizing manner is adopted for replacing a traditional air cylinder pressurizing manner, pressurizing is more stable, and the pressurizing uniformity of a polishing head is better through a center auxiliary air cylinder pressurizing manner.

Description

technical field [0001] The invention relates to the technical field of polishing machines, in particular to a polishing head structure of the polishing machine. Background technique [0002] Single-side polishing machine is currently the main equipment for processing hard and brittle materials such as monocrystalline silicon, polycrystalline silicon, electronic grade silicon, and sapphire. When the upper polishing head is used for pressure, the pressure of the polishing head cylinder will cause the processing pressure of the equipment to fluctuate and be unstable. , and the pressure on the ceramic disc is uneven. [0003] In view of the above problems, the present invention provides a polishing head structure of a polishing machine, which adopts a counterweight adjustment pressurization method and a central auxiliary cylinder pressurization method to replace the traditional cylinder pressurization method, so that the polishing head pressurization uniformity is better. Cont...
