Abstract

The invention discloses a silicon wafer polishing machine edge guide wheel. The guide wheel is fixedly connected onto a base of a silicon wafer polishing machine through a connecting arm, and comprises a rotating assembly and an outer ring, wherein the rotating assembly comprises an upper cover, a lower cover, an intermediate shaft, bearings and a bearing outer race; two bearings are mounted on the intermediate shaft in a transition fit manner, and outer edges of the two bearings are arranged in the bearing outer race in a sleeved manner through transition fit; the upper cover is positioned on the upper part of the bearing outer race, and a bulge is formed in the upper edge of the upper cover; the lower cover is positioned on the lower part of the bearing outer race, and a bulge is formed in the lower edge of the lower cover; the upper cover, the bearing outer race and the lower cover are fixedly connected through screws, and the bearing outer race is mutually meshed with the lower cover through a concave-convex staggered structure; the outer ring is mounted outside the rotating assembly; grooves are respectively formed in the upper end and the lower end of the outer ring; the groove in the upper end is clamped with the bulge in the upper edge of the upper cover; and the groove in the lower end is clamped with the bulge in the lower edge of the lower cover. The silicon wafer polishing machine edge guide wheel disclosed by the invention is capable of realizing stable rotation of a ceramic plate in the silicon wafer polishing process and is high in stability and long in service life.

Description

technical field [0001] The invention relates to an edge guide wheel of a silicon wafer polishing machine, which belongs to the technical field of silicon wafer polishing. Background technique [0002] The edge guide wheel of semiconductor silicon material polishing machine has two main functions. One is to assist in positioning the position of the ceramic plate, so that the polishing head can be accurately aligned with the ceramic plate when the polishing head is pressed down. To support the ceramic plate, the auxiliary ceramic plate rotates. During the polishing process, the edge guide wheel supports the ceramic plate from the side, and rotates with the rotation of the ceramic plate, which plays the role of positioning and auxiliary rotation. The pressing pressure of the polishing head is 300kg / cm 2 , so during the rotation of the polishing head, the edge guide wheel bears lateral force. Under the existing edge guide wheel structure, the connection between the central sha...
