The positioning device 35 lifts the positioning conveyor device 4 with the watch case 9 installed, and the watch case 9 is pressed onto the positioning top plate 352, so that the top of the watch case 9 is in a horizontal state, that is, the center line of the watch case 9 is in a vertical state. Then the locking cylinder 53 of the locking device 5 drives the locking sleeve 55 to be inserted into the driving rod 431 at the end of the bidirectional screw rod 43, and then the locking motor 54 drives the locking sleeve 55 to rotate. The locking sleeve 55 drives the bidirectional screw rod 43 to rotate through the driving rod 431, and the bidirectional screw rod 43 drives the two clamping plates 44 to move relative to each other, and presses the two ends of the watch case 9 onto the clamping plates 44, thereby realizing accurate positioning and reliable fixation of the watch case 9.

[0034] The feeding conveyor line 31 is also used for the subsequent assembly of parts and components, and cooperates with the positioning conveyor device 4 and the positioning device 35 to achieve precise positioning of each work station.

[0035] When the positioning and conveying device 4 refluxes, the positioning and conveying device 4 moves to the feed end of the feeding conveying line 31 through the reflux conveying line 32, and then the lifting cylinder 331 drives the lifting plate 333 to lift the positioning and conveying device 4, and lifts it to the feed end of the feeding conveying line 31. At this time, the moving cylinder 341 drives the moving plate 342 to be in an extended state, and the positioning and conveying device 4 is located between the moving plate 342 and the feeding conveying line 31. Then the moving cylinder 341 drives the moving plate 342 to move toward the feeding conveying line 31, and the moving plate 342 pushes the positioning and conveying device 4 onto the feeding conveying line 31.
