This significantly reduces the labor intensity of workers and improves product assembly efficiency. During operation, workers only need to place the frame on the flipping mechanism 2 at the loading station 100 and flip it 180 degrees. After flipping, the infeed transfer mechanism 3 receives the frame workpiece and moves it from the loading station 100 to the unloading station 200 to await unloading. The suction nozzle pickup mechanism 4 then picks up the frame workpiece from the infeed transfer mechanism 3, and the outfeed transfer mechanism 8 drives the suction nozzle to pick it up. The nozzle pickup mechanism 4 moves to the fastening station 300. At the same time, the worker places the back plate on the flipping mechanism 2 at the loading station 100 and flips it 180 degrees up and down. After flipping, the feeding transfer mechanism 3 resets to receive the back plate and moves it to the picking station 200. At the same time, when the nozzle pickup mechanism 4 places the frame workpiece on the fastening station 300, the nozzle pickup mechanism 4 and the discharge transfer mechanism 8 reset to the picking station 200 to pick up the back plate and move it to the fastening station 300.

Multiple non-marking suction cups 45 are provided on the lower end face of the length adjustment side plate 42 and the width adjustment side plate 41. By setting the length adjustment side plate 42 and the width adjustment side plate 41 on their sides, multiple purposes can be achieved.
