firstly, an operator places enough screws in the storage bin 400, places a plurality of wire holders in the batching box 322, starts the chain wheel and chain transmission unit 111, the chain wheel and chain transmission unit 111 can drive the bearing assembly 2 to circularly transmit on the supporting assembly 1, the two clamping plates 251 can contact more screws and scoop up a part of screws after entering the storage bin 400, only one screw can smoothly enter the clamping portion 2511, then the clamping gear 255 can rotate after contacting the first clamping rack 256 and drive the second worm wheel 253 to rotate through the second worm 254, and the second worm wheel 253 can drive the two driven wheels 252 to reversely rotate and drive the two clamping plates 251 to mutually approach to finish the clamping work of the screws; the first bevel gear 232 is driven by the two rack parts 234 arranged in a staggered manner to rotate back and forth, so that the second bevel gear 233 drives the connecting plate 231 to swing back and forth in the horizontal direction, and thus, redundant screws accumulated on the bearing component 2 fall into the storage bin 400 in the swinging process of the connecting plate 231; with the continuous rising of the bearing assembly 2, the switching gear 244 contacts the first switching rack 245 and rotates, the switching gear 244 can drive the first worm 243 to rotate and drive the first worm wheel 242 to rotate, and the first worm wheel 242 can drive the supporting plate 241 to rotate on the connecting plate 231 after rotating, wherein the supporting plate 241 can rotate 90 ° counterclockwise to ensure that the supporting plate 241 still keeps a horizontal state; then the screw passes through the lower pressing block 411 and drives the lower pressing block 411 to move downwards, the lower pressing block 411 can drive a transmission gear 422 meshed with the transmission rack 421 to rotate through the transmission rack 421, the transmission gear 422 can drive the ingredient box 322 at the upper end of the transmission gear to move towards the screw moving direction through the conveying piece 31 in the rotating process, when the screw moves to the position right below the automatic screw machine 53, the chain and sprocket transmission unit 111 stops working, the second driving piece 52 works to drive the automatic screw machine 53 to descend and fix the screw, at the moment, the first lifting rack 61 can drive the lifting gear 62 to rotate to work, the first lifting rack 61 and the second lifting rack 63 can realize reverse transmission along the vertical direction by matching with the second lifting rack 63, and meanwhile, the second lifting rack 63 and the lifting rod 64 are fixedly connected and can drive the ingredient box 322 to move in the vertical direction, therefore, when the screw moves downwards along the vertical direction, the wire holder can move upwards, after the screw and the wire holder are in mutual abutting positions, the automatic screwing machine 53 is started to drive the screw to rotate, and the wire holder cannot rotate in the mounting groove, so that the wire holder can ascend along the screw under the drive of the screw and finish assembly work with the screw; subsequently, the sprocket chain transmission unit 111 continues to drive the carrying assembly 2 to move, the clamping gear 255 contacts the second clamping rack 257 and rotates reversely to make the two clamping plates 251 separate from each other and loosen the clamped product, the switching gear 244 contacts the second switching rack 246 and rotates reversely in the process of horizontal movement, and along with the continuous movement of the carrying assembly 2, the product assembled on the carrying assembly 2 falls into the collecting box 510, so that the supporting plate 241 is reset and continues to work next time.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
