Polishing machine capable of automatically replacing polishing disc

Abstract

The invention discloses a polishing machine capable of automatically replacing a polishing disc. The polishing machine comprises a support, a fixed frame, an air cylinder, a polishing motor, a slidingblock, a sliding rail, a replacing structure, a dripping structure and a positioning clamping structure; the sliding rail is arranged on the top side of the support; the polishing motor is mounted onthe top side of the sliding block in a matched mode; the fixed frame is welded to the end of the sliding rail; the air cylinder is mounted on the fixed frame through bolts in a matched mode; the endof an actuating rod of the air cylinder is welded to the polishing motor; the replacing structure is mounted on a rotating shaft of the polishing motor in a matched mode; and a swing motor operates todrive a swing gear to rotate, a matching shaft can be driven to rotate in a matched mode under matching of a matching gear, and a mounting frame is rotated in a matched mode. According to the polishing device, a plurality of polishing pieces can be replaced in a matched mode, after replacement, the polishing motor drives the mounting frame to rotate, polishing and grinding of crystals are achieved, the polishing pieces can be replaced cyclically and periodically, the polishing efficiency can be greatly improved, and the accuracy of a polished surface can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a polishing machine capable of automatically replacing a polishing disk. Background technique [0002] Semiconductor materials are the cornerstone of the modern semiconductor industry and microelectronics industry. From a physical point of view, it refers to a class of materials whose conductivity is between conductors and insulators. [0003] There are many kinds of semiconductor materials, which can be roughly divided into three types: inorganic semiconductor crystals, organic semiconductor materials and amorphous semiconductors. At present, amorphous semiconductor materials have great application prospects in solar cells. But overall, inorganic semiconductor crystals still dominate semiconductor materials; [0004] When polishing a wafer or crystal rod, the crystal is generally polished by a polishing machine. During the polishing process, it is necessary to replace ...
