The workpieces assembled in the previous process are transported to the corrugated board side welding device 500 through the belt, and after being positioned by the tooling and positioning device, and turned 90 degrees by the turning device, the robot realizes the automatic welding of the corrugated board and the top beam.

7. Manually lift the workpiece away after welding.

8. The control system adopts PLC control, one key operation, simple and convenient operation, suitable for welding workpieces of various specifications. And the fixture can be automatically adjusted through parameter setting. Except spot welding and loading of side frames and middle ribs require manual work, the rest can realize fully automatic welding process, which can reduce 8 welding personnel and improve production efficiency.

Capacity: Design according to the capacity of JPH=8 (10 hours per shift).

Production change: This production line covers the X range: 2600mm-4500mm and Y range: 1600mm-2600mm for the products produced. When the above specifications of the workpiece are met, it is only necessary to input the corresponding product parameters in the man-machine interface, and then the servo unit on the production line will automatically adjust to achieve the production of products with other specifications of length and width.

Except for manual spot welding at the first station, the rest of the equipment is fully automatic welding. The equipment has fast welding speed, good weld quality, fully automatic control and simple operation. It greatly reduces the labor intensity of workers and improves work efficiency.
