Wafer processing steps are many, and the processing volume is very large. When wafers are processed and transferred on different processing equipment, wafer transport robots and other loading and unloading machines are required. Unloading machines are usually automated high-end precision instruments such as manipulators.
[0003] When the existing unloading machine conveying device is in use, since the end of the robot arm on the unloading machine usually needs to be in contact with the wafer and fixed, the traditional fixing process usually fixes the wafer to the end of the robot arm by electrostatic adsorption. Although the wafer is produced in a clean factory, static electricity can still easily capture and gather a small amount of impurities, causing dust particles and other impurities adsorbed on the end of the robot arm to contact the wafer, causing the wafer to be contaminated, which is not conducive to protecting the wafer; in addition, since the robot arm is combined and operated through multiple driving joints, long-term operation can easily cause wear on the joints, and the traditional lubrication method requires the unloading machine to be stopped before it can be carried out, resulting in the robot arm on the unloading machine not being lubricated in time, which can easily shorten the service life of the robot arm.
