Description

Technical Field

[0001] The utility model relates to the technical field of seat assembly, in particular to a seat assembly device for preventing backrest deviation. Background Art

[0002] The seat assembly device is a device that assembles the seat cushion and backrest of the car seat when assembling car parts. The seat tightening station is connected to the MES by a barcode scanner gun. The MES provides an interface. The assembly PLC sends a seat arrival signal to the robot PLC. The robot confirms whether the seat direction is correct. The MES is responsible for providing the seat configuration barcode information to the robot and the electric gun. The robot calls the corresponding product trajectory and uses the visual system to locate the bolt. After the position is successful, it outputs a signal to the electric gun. The electric gun performs the tightening operation based on the received barcode information and the start signal. During the tightening process, the tightening gun sends a qualified signal to the robot. If qualified, the robot proceeds to the next step. If unqualified, the robot performs a re-hit. If the re-hit is unqualified, the robot returns to the origin, and the tightening gun uploads the tightening torque data to the MES. After the robot returns to the origin, the release signal is sent to the assembly PLC, and the station is released. If unqualified, the on-site The team leader confirms and manually presses the bad button to release the signal to the next workstation, which then uses the spare gun to make up for the tightening. The robot tightening station presses the origin button to return and waits for the next workpiece. However, in the use of traditional seat assembly devices, the traditional seat assembly device transports the seat to the processing station through the production line transmission structure, uses the visual system to locate the product by calling the product trajectory, and outputs signals to the electric gun for tightening. However, when the traditional seat assembly device assembles the seat, the backrest and seat cushion lack a fixed structure before assembly. The backrest and seat cushion may be offset during assembly, which affects the normal progress of the seat assembly work. Utility Model Content
