A polishing machine capable of automatically replacing polishing discs

Abstract

The invention discloses a polishing machine capable of automatically replacing a polishing disc, comprising a bracket, a fixed frame, a cylinder, a polishing motor, a slider, a slide rail, a replacement structure, a trickle structure and a positioning and clamping structure. The top side of the bracket is Slide rails are arranged, the top side of the slider is equipped with a polishing motor, the fixed frame is welded on the end of the slide rail, the cylinder is mounted on the fixed frame through bolts, and the action rod of the cylinder The end is welded on the polishing motor, and the replacement structure is matched and installed on the rotating shaft of the polishing motor. Through the operation of the swing motor, the swing gear is driven to rotate. With the cooperation of the matching gear, the matching shaft can be driven to rotate, and the mounting frame is coordinated to rotate. Multiple polishing sheets can be replaced together. After the replacement, the polishing motor drives the installation frame to rotate to realize the polishing and polishing of the crystal. The polishing sheet can be replaced in a cycle, which can greatly improve the polishing efficiency and ensure the accuracy of the polished surface.

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 ...
