Product Introduction
Basic operation process:
ï?¼Loading by AGV robots, printing QR codes based on the product work order issued by the SAP system, and then separating the upper and lower shells.
ï?¼Bottom coating of the upper shell: The installation of three components is completed through ten processes, and after each assembly is completed, there is a corresponding installation accuracy testing process to ensure that the assembly is completely qualified.
ï?¼Installation of lower shell components, upper and lower shell assembly: A total of 25 processes are used to install 12 components. After each part is assembled, guide pins are used to ensure the upper and lower assembly. After the installation of internal components is completed, the product's on/off function is tested. After passing the test, rivets are installed, pressed again, and the screws are removed. All installations are checked, and after passing the test, they are transferred to the inspection station.
ï?¼Unipolar products undergo instantaneous detection, delay detection, cooling tower and other unit inspections, and are then labeled with QR codes and covers before being transferred to the next workstation.
ï?¼Multi pole products require 9 steps of multi pole assembly, and after assembly, a second delay is performed to verify the stability and reliability of the product
