starting equipment, driving the device to a specified spinning position through the truss 54 on the spinning manifold 56, and after the device reaches the specified spinning position, sending a feedback signal by the photoelectric sensor 58 on the spinning manifold 56 corresponding to the spinning position so that the truss 54 immediately stops the translation action, and simultaneously starting the first servo motor 18;

thirdly, the first servo motor 18 drives the gear 17 to rotate through the first worm and gear reducer 19, the gear 17 is meshed with the rack 16 and drives the beam 12 to move horizontally, the spinning assemblies 52 mounted on the screwing assembly 55 are driven to move in the horizontal direction and extend into the spinning box 56, each spinning assembly 52 corresponds to the corresponding assembly mounting hole in the vertical direction, and at the moment, the photoelectric sensor 58 on the beam 12 sends a feedback signal, so that the first servo motor 18 stops working immediately;

fourthly, the spinning assemblies 52 arranged on the cross beam 12 and the tightening assembly 55 are driven by the truss 54 to vertically move upwards, when the upper ends of the spinning assemblies 52 are exactly aligned with the corresponding assembly mounting holes and the supporting plate 30 is in contact with the limiting block 27, the photoelectric sensor 58 on the truss 54 sends a feedback signal and enables the feedback signal to stop working immediately, and the second servo motor 22 starts working immediately;

the second servo motor 22 drives the screwing components 55 and the spinning components 52 to rotate forward synchronously through the second worm gear reducer 23, the upper end of each spinning component 52 is screwed on the corresponding component mounting hole gradually, the spinning components 52 move upwards gradually in the process of screwing the spinning components 52, so the supporting seat 32 can follow up and drive the positioning plate 24 to move upwards under the action of the supporting spring 29, the movement of the positioning plate 24 is transmitted through the ejector rod 51 and converted into the upward movement of the detection block 49, when the spinning components 52 are screwed in place, the photoelectric sensor 58 mounted at the lower end of the vertical plate 45 sends a feedback signal to stop the second servo motor 22, and the installation of the spinning components 52 is completed. The disassembly process of the spin pack assembly 52 is reversed from that described above.

The equivalent substitution or change made by the technical personnel in the technical field on the basis of the invention is all within the protection scope of the invention. The protection scope of the invention is subject to the claims.
