Problems solved by technology

When the manipulator picks and places the wafer, due to the influence of factors such as environmental temperature changes, load changes, and mechanical structure deformation, the manipulator picks and places the wafer on the support mechanism according to the position coordinates stored offline, resulting in collisions. Risk of overcatch or damage to equipment, resulting in irreparable losses
At the same time, due to the thermal deformation of the wafer during the heat treatment process, the actual distribution state of the wafer will be different from the offline teaching position parameters, making the movement of the manipulator in an unsafe state
In addition, at present, different types of manipulators are placed in each process link for single-functional grabbing, and fully automatic (partially automatic) integration involving wafers from ingots / shaping / cutting / grinding / etching / polishing / cleaning A single type of manipulator cannot satisfy multiple types of grasping in a small space during chemical processing
