When the four clamps 312 are pushed open by the clamp telescopic cylinder 311 to clamp the edge of the frame 100, the clamp back pressure cylinder 313 extends to firmly press the frame 100 to prevent the frame 100 from loosening and slipping when the freedom robot 3 moves. When the above-mentioned tooling clamps the top frame 100 of the frame pallet 2 from the inside, the freedom robot 3 sends the frame 100 to the transmission line device 1 of the loading station 101 to implement the next step. In the present invention, when changing different models of products, only the screws on the adjusting device can be adjusted to adjust the size of the clamp 312 to adapt to the grasping of different products. When the frame 100 is placed on the transmission line device 1, the corresponding detector on the transmission line device 1 detects the signal and starts the transmission line device 1, drags the frame 100 on the transmission line device 1 to the next station, and the transmission line device 1 has a width adjustable function. .

In the present invention, after the mirror frame 100 flows on the transmission line device 1 to the specified position of the mirror frame assembly device 5, the detector at the mirror frame assembly device 5 detects it, and the blocker starts to block the mirror frame 100, and the transmission line device 1 stops transmitting. The transmission line device The positioning cylinder 52 at position 1 pushes the mirror frame 100 to the specified position 50 on one side of the assembly line to ensure that the mirror frame 100 can be accurately positioned. The DOF robot 3 moves to the corresponding position of the mirror 102, and the mirror suction cup 314 slowly approaches the mirror 102. There is a laser ruler (not visible in the figure) near the mirror suction cup 314. The laser ruler can sense the distance between the mirror suction cup 314 and the mirror 102 in real time.
