[0031] Working principle: When the utility model works, it is divided into the following processes:

[0032] 1. Height adjustment

[0033] When height adjustment is required, first the first motor 7 in the height adjustment assembly 2 works, and the rotation drives the screw rod 10 to work. As the screw rod 10 rotates, the linear bearing moves on the screw rod 10, thereby driving the first slide 11 to move on the first guide rod 8 and the second guide rod 9, thereby driving the second slide 12 to follow and move on the first guide rod 8 and the second guide rod 9, thereby achieving height adjustment of the manipulator assembly 3;

[0034] 2. Material gripping

[0035] When clamping materials, the clamping jaw 24 is first located at the lower left side. When the clamping jaw 24 clamps the material, the second motor 15 in the manipulator assembly 3 rotates, driving the rotating plate 16 to rotate, thereby driving the following block on the slide plate 22 to move in the travel groove on the travel plate 17 through the following groove on the rotating plate 16. At this time, the second slide rail 21 moves upward in the second slider 20. At the same time, with the movement of the slider, at the corner, the first slider 19 moves to the right on the first slide rail 18, thereby traveling through the entire travel groove to put down the material, thereby completing the entire clamping work.

[0036] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
