[0064] Working principle: when assembling the extractor, the extractor shell, the torsion spring and the buckle are transported by the first conveying belt 11, the second conveying belt 13 and the third conveying belt 16 respectively; when the first conveying belt 11 transports the extractor shell to the designated position, the first pushing cylinder 12 drives the push rod 121 to move and push the extractor shell into the first work position groove 21 for assembly work;

[0065] When the second conveying belt 13 transports the torsion spring to the designated position, the second cylinder 64 drives the fourth jaw cylinder 65 to descend so that the fourth jaw cylinder 65 clamps the torsion spring, and after the fourth jaw cylinder 65 clamps the torsion spring, the second cylinder 64 drives the fourth jaw cylinder 65 to ascend, the second motor 62 drives the second screw 63 to rotate, so that the second sliding block 61 slides along the second sliding groove 141, thereby moving the fourth jaw cylinder 65 to the top of the extractor shell on the first work position groove 21, and the second cylinder 64 drives the fourth jaw cylinder 65 to descend so that the fourth jaw cylinder 65 places the torsion spring in the extractor shell;

[0066] When the torsion spring is placed in the extractor shell, the second pushing cylinder 15 drives the top rod 151 to push the pin placed on the placing block 24 into the extractor shell on the first work position groove 21, so that the pin fixes the torsion spring, and after the pin is installed, the third cylinder 22 drives the push block 23 to move towards the third cylinder 22, so as to place a new pin on the placing block 24, and after the new pin is placed on the placing block 24, the third cylinder 22 drives the push block 23 and the placing block 24 to move away from the third cylinder 22, so as to install the pin into the extractor shell again by the second pushing cylinder 15;

[0067] When the buckle is transported by the third conveying belt 16 into the third sliding groove 33, the third pushing cylinder 34 drives the first push plate 341 to push the buckle to the second push plate 171, and when the extractor shell is placed at the second work position groove 31, the fourth feeding cylinder 17 drives the second push plate 171 to push the buckle into the extractor shell for assembly;

[0068] When the extractor shell is assembled on the first assembly table 2, the first cylinder 53 drives the first jaw cylinder 54 to move down to hold the extractor, then the first motor 571 drives the first screw 572 to rotate, so that the first sliding block 52 slides along the first sliding groove 51, so that the first jaw cylinder 54 holds the extractor shell in the first work slot 21 and sends it to the transfer table 4. While the first jaw cylinder 54 moves, the second jaw cylinder 55 holds the extractor shell placed on the transfer table 4 and sends it to the second work slot 31. The third jaw cylinder 56 holds the assembled extractor in the second work slot 31 and sends it to the collection for collection, realizing the synchronous movement of the workpieces in multiple workstations, reducing the time consumed by the workpiece transfer, and improving the work efficiency of the extractor assembly work.

[0069] When the extractor shell with torsion spring and latch is placed on the second work slot 31, the fourth cylinder 321 drives the clamping plate 322 to move towards the second work slot 31, so that the clamping plate 322 fixes the extractor shell placed in the second work slot 31.

[0070] When installing the extractor shell, buckle and spring in the second work slot 31, the spring to be assembled is conveyed to the first material conveying channel 331 through the second material conveying channel 332. When the fourth material conveying cylinder 17 drives the second push plate 171 to push the buckle into the extractor shell, the fifth material conveying cylinder 35 is started to drive the third push plate 351 to move up, and the third push plate 351 sends the spring in the first material conveying channel 331 to the top of the first material conveying channel 331. The buckle is installed in the extractor shell, and the spring is installed on the buckle at the same time, and the whole extractor assembly work is completed.

[0071] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape and principle of the present application shall be covered within the protection scope of the present application.
