After the receiving mechanism 2 receives the cylindrical battery from the pressing device, it sends the cylindrical battery to the transfer channel 31, and the transfer plate 32 pushes the cylindrical battery to move. From a top view, the transfer plate 32 rotates in a clockwise direction. When the cylindrical battery reaches the position corresponding to the defective product feeding mechanism 4, if the current cylindrical battery is a defective product, the driving component 34 drives the pusher component 33 to push the cylindrical battery into the defective product discharging mechanism 5. If the cylindrical battery is a good product, the cylindrical battery continues to move to the position corresponding to the discharging mechanism 5 and enters the discharging mechanism 5.

[0025] The pusher assembly 33 includes a pusher 331 rotatably connected to the middle turntable 32, a guide portion 332 disposed at the bottom of the pusher 331, and the middle turntable 32 is provided with a guide opening 35 corresponding to the guide portion 332.

[0026] The driving assembly 34 includes a pusher drive member 341 and a push block 342 connected to the output end of the pusher drive member 341. In this embodiment, the pusher drive member 341 adopts a cylinder. When the cylinder piston rod is extended, the pusher 331 rotates, thereby pushing the cylindrical battery to the defective product feeding mechanism 4. The pusher 331 is provided with a lower recess 333 corresponding to the push block 342, so that the pusher 331 forms a stepped structure, which is convenient for the push block 342 to push. In addition, a spring is connected between the pusher 331 and the turntable 32 to facilitate resetting.

[0027] The middle turntable 32 is provided with a material tray 36, and the edge of the material tray 36 is evenly provided with a plurality of first accommodating parts 361 for accommodating cylindrical batteries. At the same time, the cylindrical batteries are placed on the cup during the transfer process. Since the material tray 36 is higher than the cup, the position of the middle turntable 32 corresponding to the material tray 36 also needs to be provided with a cup accommodating part. The first accommodating part 361 of the material tray 36 and the cup accommodating part of the middle turntable 32 correspond to each other. In addition, the second accommodating part 43, the third accommodating part 53 and the fourth accommodating part mentioned in this embodiment can be applied to the cup or the cylindrical battery according to their specific heights.

In this embodiment, the feeding tray 42 rotates in a counterclockwise direction to facilitate pushing defective products sent out by the transfer sorting mechanism 3 into the feeding channel 41. The feeding channel 41 is connected to a storage channel 44, and cylindrical batteries are transferred from the feeding channel 41 to the storage channel 44 for temporary storage, waiting to be taken away.

[0029] The receiving mechanism 2 includes a receiving channel 21 disposed on the machine 1, and a receiving tray 22 disposed on the machine 1 for transferring cylindrical batteries from the receiving channel 21 to the transfer and sorting mechanism 3, and a plurality of fourth accommodating portions are evenly disposed on the edge of the receiving tray. In this embodiment, the receiving tray rotates counterclockwise to facilitate the delivery of cylindrical batteries to the transfer tray 32 of the transfer and sorting mechanism 3.

[0030] The discharging mechanism 5 includes a discharging channel 51, which is used to transfer cylindrical batteries from the transfer sorting mechanism 3 to the discharging tray 52 of the discharging channel 51. The edge of the discharging tray 52 is evenly provided with a plurality of third accommodating portions 53 for accommodating cylindrical batteries. When the qualified product reaches the position corresponding to the discharging channel 51, it enters the discharging channel 51 with the cooperation of the discharging tray 52, and moves along the discharging channel 51 under the push of the discharging tray 52.

The inspection process can be carried out by visual inspection and other methods. The marked defective products can be accurately removed to the defective product feeding mechanism 4 when passing through the transfer sorting mechanism 3. The end cap pressing equipment sends out the cylindrical battery after completing the pressing operation. The receiving mechanism 2 receives the cylindrical battery and transfers the cylindrical battery to the transfer sorting mechanism 3. In the process of moving the cylindrical battery, the transfer sorting mechanism 3 uses the pushing component 33 to push the marked defective products into the feeding tray 42 of the defective product feeding mechanism 4. The feeding tray 42 pushes the defective products into the feeding channel 41 and finally reaches the storage channel 44. The good products enter the discharge channel 51 of the discharge mechanism 5 under the push of the transfer tray 32, and are pushed into the conveying channel 54 through the discharge tray 52 and sent to the next process.

[0033] The receiving mechanism 2 of the utility model receives the cylindrical batteries from the pressing device of the end cover and enters the transfer sorting mechanism 3. With the cooperation of the driving component 34 and the pushing component 33, the marked defective products are sent to the defective product feeding mechanism 4, and the good products are sent to the discharging mechanism 5, which sends them to the next process. No manual operation is required to avoid missing defective products. The entire sorting and discharging process is basically automated, which improves production efficiency and reduces production costs.
