After cleaning and gluing, the sensor cover will be placed on the transfer fixture of the sensor cover oiling detection and transfer unit by the robot unit. At this time, the sensor cover installation unit will run to the material picking point through multiple sets of servo components, remove the sensor cover from the sensor cover transfer fixture, run to the installation position, and install the sensor cover on the steering gear body. The pressure and displacement of the sensor cover will be monitored during the process. At this point, the entire assembly process is completed.
