[0036] After the car side panel is formed by stamping, there are burrs on the lower edge of the stamping part. The car side panel workpiece taken out of the stamping die is transported to a designated position on one side of the worktable by the car side panel loading and conveying device 2. Then, the car side panel loading robot 7 moves it to the car side panel support block 31 of the car side panel positioning device 3. At this time, the car side panel positioning pin 32 is in the extended state, and the positioning holes on the car side panel are aligned with each of the car side panel positioning pins 32, realizing the initial positioning of the car side panel. Then, the car side panel fixing mechanism is activated to fix the car side panel to the car side panel support block 31.
