This production line effectively incorporates industrial robot technology, grinding detection technology, logistics transportation technology and mirror shell production of rearview mirror. With this advantage, it approaches the technological applications such as automatic loading of turnover box truss, automatic production of mirror shell, automatic blanking of mirror shell, automatic detection of mirror shell, automatic grinding of mirror shell, automatic packing of mirror shell, automatic off-line stacking of turnover box, etc. The production line is connected with the upstream and downstream production lines of workshop through AGV, thus realizing unmanned.
