S1: a plurality of left lock bodies A are correspondingly placed in left positioning units L on positioning assemblies 2 in sequence, a plurality of right lock bodies B are correspondingly placed in right positioning units R on positioning assemblies 2 in sequence, when one positioning assembly 2 rotates to the lower side of a seat plate 1-6 of a grabbing assembly 1 along with a rotating ring disc 6, a lifting cylinder 1-5 drives the seat plate 1-6 to move downwards, then a straight claw cylinder 1-7 drives a claw 1-8 to grip a corresponding left lock body A or right lock body B, the lower end of a 7-shaped pressing plate 1-9 is abutted against the upper end face of the left lock body A or the right lock body B, then the lifting cylinder 1-5 drives the seat plate 1-6 to move upwards, then a piston rod of the cylinder 1-4 extends to enable a sliding plate 1-3 to move forwards, when the left lock body A or the right lock body B gripped by the claw 1-8 correspondingly moves forwards to the right side of a material placing plate 3-2, the lifting cylinder 1-5 drives the seat plate 1-6 to move downwards, and then the straight claw 1-7 drives the claw 1-8 to enable the left lock body A or the right lock body B to be pressed against the upper end of the material placing plate 1-9;

S2: then, the straight claw cylinder II 3-3 drives the claw II 3-4 to clamp the corresponding left lock body A or right lock body B, then the cylinder II 3-6c drives the sliding seat I3-6 d and the sliding seat II 3-6e to move backwards until the lug block 3-6i is attached to the limit post 3-6h, and the piston rod of the cylinder II 3-6c stops moving, and in the process, the core block 3-6f is slowly inserted into the slot A-1 on the corresponding left lock body A or right lock body B: if the core block 3-6f can be completely inserted into the corresponding slot A-1, the vertical section of the 7-shaped shading sheet 3-6k is completely staggered with the light path channel 3-6j-1 on the corresponding photoelectric sensor 3-6j, which indicates that the perpendicularity of the pins on the lock body is good: otherwise, if the core block 3-6f cannot be completely inserted into the corresponding slot A-1, the vertical section of the 7-shaped light shielding sheet 3-6k stretches into the light path channel 3-6j-1 on the corresponding photoelectric sensor 3-6j to block the light path, so that the perpendicularity of the pins on the lock body is unqualified;

S3: after the detection is finished, the piston rod of the cylinder II 3-6c is contracted and reset, the sliding seat I3-6 d and the sliding seat II 3-6e are driven to move forwards, the straight claw cylinder II 3-3 drives the clamping jaw II 3-4 to loosen the corresponding left lock body A or right lock body B, the lifting cylinder 1-5 drives the seat board 1-6 to move downwards, then the straight claw cylinder I1-7 drives the clamping jaw I1-8 to grasp the corresponding left lock body A or right lock body B, the lifting cylinder 1-5 drives the seat board 1-6 to move upwards, then the piston rod of the cylinder I1-4 is contracted and reset to enable the sliding plate 1-3 to move backwards until the left lock body A or right lock body B grasped by the clamping jaw I1-8 is correspondingly positioned right above the positioning assembly 2, the lifting cylinder 1-5 drives the seat board 1-6 to move downwards, the straight claw cylinder I1-7 drives the clamping jaw I1-8 to loosen the corresponding left lock body A or right lock body B and place the corresponding left lock body A or right lock body B inside the corresponding left positioning unit L and right positioning unit R on the positioning assembly 2, and the rotating ring 6 is rotated, and the steps of the steps S1-S3 are repeated.

The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that it will be apparent to those skilled in the art that several modifications and variations can be made without departing from the technical principle of the present utility model, and these modifications and variations should also be regarded as the scope of the utility model.
