[0036] The frame 1 is provided with a plurality of flat suction cups 3. The flat suction cups 3 are used to adsorb the upper surface of the parts after laser processing. Each flat suction cup 3 is connected to a vacuum generator 4.

[0041] The dynamic sealing assembly includes a support spring 15 and a one-way exhaust valve 16. The support spring 15 is arranged at the divergent end of the dovetail groove 14. When the air in the dovetail groove 14 is exhausted, the support spring 15 is compressed under force. When air enters the dovetail groove 14, the volume of the dovetail groove 14 will increase.

[0044] Working principle: When in use, the flat suction cup 3 is attached to the upper surface of the part by the robotic arm, and the vacuum generator one 4 is started to make the flat suction cup 3 adsorb to the part (at this time, the air in the dovetail groove 14 is exhausted, and the support spring 15 is compressed under force); according to the position of the holes of the part, the arc suction cup 2 is inserted into the hole by the lifting cylinder 5, and then the inner suction cup 201 and the outer suction cup 202 of the arc suction cup 2 are both attached to the inner side wall of the part hole by the fitting push rod. When attaching, the air in the outer suction cup 202 is exhausted by extrusion, and the vacuum generator two 11 is started to suck out the air in the inner suction cup 201;

[0045] During the process of transporting the part, when the vacuum degree of the inner suction cup 201 drops, air will first enter the dovetail groove 14. At this time, the volume of the dovetail groove 14 will increase, the support spring 15 resets synchronously and further extracts the air between the inner suction cup 201 and the part through the one-way exhaust valve 16, improving the adhesion between the inner suction cup 201 and the part.

[0046] The air input by the movement of the piston 17, the air extracted by the vacuum generator two 11, the air discharged when the lifting cylinder 5 shortens, and the air discharged when the fitting push rod shortens will all be stored in the gas storage cylinder 18. When the lifting cylinder 5 is reset, the electromagnetic exhaust valve 19 will be continuously opened to clean the surface of the part.
