The pallet 6 loaded with workpieces is conveyed forward from the forward conveying line 2, and can pass through the required processing stations, such as assembly, welding, grinding and other processes during this conveying process. During the processing, the loading and lifting mechanism 4 descends to the same height as the backward conveying line 3. After processing, the pallet 6 loaded with workpieces enters the unloading and lifting mechanism 5; at this time, the workpiece on the pallet 6 can be removed, and the empty pallet is lowered by the unloading and lifting mechanism 5 to the same height as the backward conveying line 3.
