The hand claw driving device 42 drives the clamping driving block 422 and the clamping claw 412 to rise and then open outward; after the clamping claw 412 is opened, the hand claw driving device 42 drives the clamping driving block 422 and the clamping claw 412 to descend, so that the bottom end of the clamping claw 412 falls into the clamping through hole 113; at this time, the hand claw driving device 42 drives the clamping driving block 422 and the clamping claw 412 to close inward, so that the clamping claw 412 abuts against the inner surface of the rectangular ring to close inward; thereby realizing the grabbing and compression of the rectangular ring by the assembly hand claw 41.

[0063] 4. After the assembly gripper 41 completes the grabbing and compressing function, the adjusting module 5 drives the assembly gripper 41 to ascend, and the rectangular ring is sent to the corresponding installation position (it is worth noting that in this process, according to the model, inner diameter size and other problems of the rectangular ring, after the adjusting module 5 drives the assembly gripper 41 to ascend and the tensioning claw 411 leaves the material taking through hole 112, the gripper driving device 42 can also drive the tensioning driving block 421 and the tensioning claw 411 to open outward to a certain extent, so that the assembly gripper 41 can more firmly grab the rectangular ring).

[0064] 5. After the adjusting module 5 drives the assembly gripper 41 to send the rectangular ring to the corresponding installation position, the gripper driving device 42 drives the clamping driving block 422 and the clamping claw 412 to ascend, and then to inwardly close, so as to release the compression and grabbing of the rectangular ring, and the rectangular ring is installed through its own reset effect.

[0065] 6. The gripper driving device 42 drives the clamping driving block 422 and the clamping claw 412 to fall, so that the clamping claw 412 returns to the inner ring of the rectangular ring; the gripper driving device 42 drives the clamping claw 412 to open outward, to assist the rectangular ring to reset and install (it is worth noting that at this time, the gripper driving device 42 can also drive the tensioning driving block 421 and the tensioning claw 411 to open, to assist the rectangular ring to reset and install, and also to avoid the situation that the rectangular ring is deformed or the surface is adhered to the tensioning claw 411 and cannot be automatically reset during the compression process; and the gripper driving device 42 can also drive the tensioning claw 411 and the clamping claw 412 to open and close continuously for several times according to the installation of the rectangular ring, to realize high-quality rectangular ring installation).

[0066] 7. After the rectangular ring is installed, the gripper driving device 42 drives the tensioning claw 411 and the clamping claw 412 to close and reset, for subsequent new work.

[0067] It is worth noting that other technical solutions of the utility model belong to the prior art, and therefore are not described in detail.

[0068] The above is only the preferred embodiment of the utility model, and it should be pointed out that for ordinary skilled persons in the technical field, several improvements and refinements can be made without departing from the concept of the utility model, and these improvements and refinements should also be regarded as the protection range of the utility model.
