Description

[0002] A letter box is a facility used to receive and store letters, parcels or other small items. It is widely used in residential areas, commercial office buildings, schools, hospitals and other places. During the production and processing of letter boxes, welding production lines are usually used to assemble and weld the letter boxes.

[0003] When assembling and welding the letter box, the staff needs to place the letter box frame on the placement plate, and start the motor to drive the positioning plate to move through the bidirectional threaded rod. The positioning plate drives the letter box frame to move and position and fix the letter box frame. Then use the intelligent device to scan the letter box frame and transmit the data to the control device. Finally, the control device controls the robotic arm device to assemble and weld the letter box.
