[0026] In this embodiment, the transfer mechanism 2 includes an electric motor 201, which is connected to one side of the top of the bracket 101 by bolts. The output end of the electric motor 201 is provided with a screw rod 202 through a coupling, and a moving rod 203 is threadedly connected to the screw rod 202. The other end of the moving rod 203 is slidably connected with a slide rod 204. The middle position of the moving rod 203 is connected to a No. 1 cylinder 205 by bolts, and the output end of the No. 1 cylinder 205 is connected to a transfer plate 206 by bolts. The bottom of the transfer plate 206 is connected to a plurality of claw cylinders 207 by bolts, and the claw ends of the claw cylinders 207 are connected to the transfer plate 206 by bolts. There are two clamps 208 connected by bolts on the inside, and the conveyor belt 103 transfers the chargers arranged in sequence to the position of the bracket 101. The motor 201 is used to drive the screw rod 202. The screw rod 202 adjusts the position of the moving rod 203 to be directly above the charger. The No. 1 cylinder 205 pushes the transfer plate 206 down. After several claw cylinders 207 under the transfer plate 206 are close to the charger, the claw cylinder 207 drives the claw clamp 208 to clamp each charger, and cooperates with the screw rod 202 and the No. 1 cylinder 205 to move the charger to the rear support mechanism 3 position.

[0027] In this embodiment, the bearing mechanism 3 includes a plurality of parallel guide blocks 301, the spacing between the chargers is controlled to be consistent with the spacing between the moving seats 302, the claw cylinder 207 can transfer the charger to the top of the moving seat 302, the guide block 301 is welded to the top of the workbench 102, one end of the screw rod 202 is located obliquely above the conveyor belt 103, and the other end of the screw rod 202 is located above the front end of the guide block 301, the top of the guide block 301 is slidably connected to the moving seat 302, one side of the moving seat 302 is connected to a connecting plate 303 by bolts, and the tops of both ends of the connecting plate 303 are connected to the rotating cylinder 3 by bolts. 04, the output end of the rotating cylinder 304 is connected to a rocker 305, and the tops of the two rockers 305 are connected to a limit plate 306 for common rotation. The top of the workbench 102 is connected to a No. 2 cylinder 307 by bolts, and the output end of the No. 2 cylinder 307 is fixedly connected to a moving block 308. The moving block 308 is connected to the middle position at the bottom of the connecting plate 303 by bolts. Through the simultaneous operation of the two rotating cylinders 304, the rockers 305 are rotated synchronously, and the rocker 305 moves the limit plate 306 to above the charger on the moving seat 302, and then the rotating cylinder 304 retracts to press the charger to the bottom of the limit plate 306.

[0028] In this embodiment, the automatic screw locking mechanism 4 includes a mounting frame 401, which is welded to the top of the workbench 102, and the mounting frame 401 is located above the rear side of the guide block 301. The top of the mounting frame 401 is connected to the No. 3 cylinder 402 by bolts, and the output end of the No. 3 cylinder 402 is connected to a movable sleeve block 403, and the movable sleeve block 403 is slidably connected to the top of the mounting frame 401. The side of the movable sleeve block 403 is connected to the No. 4 cylinder 404 by bolts, and the output end of the No. 4 cylinder 404 is connected to a lifting plate 405, and the front side of the lifting plate 405 is connected to a plurality of screw feeding assemblies 406 by bolts. Several electric screwdrivers 407 are fixedly installed on 405. When the mobile seat 302 brings several chargers to the position of the automatic screw locking mechanism 4, the No. 4 cylinder 404 pushes the lifting plate 405 down. First, the screw feeding assembly 406 conveys the screw to the screw hole on the charger, and then the electric screwdriver 407 is aligned with the screw position to lock it. In this process, the No. 2 cylinder 307, the No. 3 cylinder 402 and the No. 4 cylinder 404 cooperate with each other to adjust the corresponding positions of the screw hole and the screw feeding assembly 406 and the electric screwdriver 407, so as to realize the screwing work on multiple chargers at the same time.

[0029] Working principle: The conveyor belt 103 transfers the chargers arranged in sequence to the position of the bracket 101. The spacing between the chargers is controlled to be consistent with the spacing between the mobile seats 302. The motor 201 drives the screw rod 202. The screw rod 202 adjusts the position of the mobile rod 203 to be directly above the charger. The No. 1 cylinder 205 pushes the transfer plate 206 down. After the claw cylinders 207 under the transfer plate 206 are close to the charger, the claw cylinders 207 drive the claws 208 to clamp each charger. The device cooperates with the screw rod 202 and the No. 1 cylinder 205 to move the charger to the rear bearing mechanism 3 position. After the claw cylinder 207 transfers the charger to the top of the mobile seat 302, the No. 1 cylinder 205 retracts. Through the simultaneous operation of the two rotating cylinders 304, the rocker 305 rotates synchronously. The rocker 305 moves the limit plate 306 to the top of the charger on the mobile seat 302, and then the rotating cylinder 304 retracts to press the charger to the bottom of the limit plate 306. In the next step, the No. 2 cylinder 3 07 pulls the moving block 308 backward, and the moving block 308 drives the connecting plate 303 and each moving seat 302 to move backward together. When the moving seat 302 brings several chargers to the position of the automatic screw locking mechanism 4, the No. 4 cylinder 404 pushes the lifting plate 405 down. First, the screw feeding component 406 conveys the screw to the screw hole on the charger, and then the electric screwdriver 407 is aligned with the screw position to lock it. In this process, the No. 2 cylinder 307, the No. 3 cylinder 402 and the No. 4 cylinder 404 cooperate with each other to adjust the screw hole position and the corresponding position of the screw feeding component 406 and the electric screwdriver 407, so as to realize the screwing work on multiple chargers at the same time. After the work is completed, the No. 2 cylinder 307 pushes the moving block 308 forward, and then the rotating cylinder 304 releases the restriction on the charger. The transfer mechanism 2 moves the charger to the top of the conveyor belt 103, and the conveyor belt 103 sends it away, and then the next batch of chargers is sent, and the work is cyclical, with a high degree of automation, which greatly improves the production efficiency.
