Manufacture method of carbon brush, manufacture method of carbon rod and carbon brush

Abstract

The invention discloses a manufacture method of a carbon brush, a manufacture method of a carbon rod and the carbon brush. The manufacture method of the carbon brush comprises the following steps: mixing graphite powder, lead powder and copper powder to obtain a mixture, wherein, the mixture comprises, by weight, 71%-79% of the graphite powder, 17%-23% of the lead powder and 4%-6% of copper powder; adding a bonding agent into the mixture to carry out uniform mixing; carrying out moulding processing on the mixture which is added with the bonding agent, and heating the mixture after moulding; carrying out graphitization processing on the mixture after heating to obtain the carbon rod; connecting one end of a spring with one end of the carbon rod, connecting the other end of the spring with one end of a connection shaft with conductivity, and fixing the other end of the connection shaft with a backseat.

Description

technical field [0001] The invention relates to the field of manufacturing integrated circuit packaging equipment, in particular to a method for manufacturing a carbon brush, a method for manufacturing a carbon rod, and a carbon brush. Background technique [0002] The working mechanism of the dicing machine is to process the workpiece through powerful grinding. In the dicing machine, the aerostatic electric spindle is the executive part of the powerful grinding. The height measuring carbon brush is used to measure the position height of the aerostatic electric spindle. This height determines the cutting depth of the dicing machine. [0003] Since the dicing machine requires high cutting accuracy when cutting the workpiece, many external factors will affect the accuracy of the height measurement process, and once the height measurement process is inaccurate or invalid, the workpiece will be damaged or scrapped. [0004] When the dicing machine is working, the high-speed rot...
