The first fork arm 76 and the second fork arm 77 have the same structure. After the turntable 763 on the two forks clamps the component, the tilting motor 762 drives the turntable 763 to rotate and change the posture of the component. The turntable 763 is an electric suction cup, which can stably clamp components of different shapes.

[0035] One end of the boom 764 is slidably connected to the lifting platform 73, and the other end extends outward. The push rod 761 is an active drive device used to push the boom 764 to move laterally on the lifting platform 73.

The gantry device 3 is a gantry crane.

[0046] Preferably, a semi-enclosed protective railing 6 is provided on the sides of the first assembly robot 4 and the second assembly robot 5.

[0047] The working process of this automatic flipping and positioning machine is as follows:

[0048] The second assembly robot 5 takes the material from the rack and places it on the second conveyor line 2. Then, the second assembly robot 5 takes out another material and stacks it for assembly. After assembly, it is sent to the first assembly robot 4 by the second conveyor line 2 for screw tightening. Then, the second conveyor line 2 sends the material to the automatic flipping and positioning machine 7 for posture adjustment and then sends it back to the second assembly robot 5 for material stacking. Then, it is sent to the first assembly robot 4 for screw tightening. The reciprocating motion completes the assembly and fixing of multiple materials. After assembly, it is sent to the end of the second conveyor line 2 and then removed by the gantry device 3. On the first conveyor line 1, the second assembly robot 5 also completes the material picking and assembly. The two robots work on two production lines at the same time, reducing the waiting time of the robots.
