A detection channel 25 is provided on the detection block 6, and the bottom surface of the detection channel 25, the bottom surface of the feeding channel 22, and the bottom surface of the discharge channel 24 are flush, and the left end of the detection channel 25 is connected to the feeding channel 22, and the right end of the detection channel 25 is connected to the discharge channel 24, and the inner diameter of the detection channel 25 is adapted to the outer diameter of the battery shell;

[0029] An undersized sorting component, the undersized sorting component includes a detection roller group installed on a detection frame 7 and a driving device for driving the detection roller group to rotate. A receiving box 8 is installed on the detection frame 7 below the detection roller group. The detection roller group is arranged obliquely, and its inclination angle is 20°. The detection roller group includes a first detection roller 26 and a second detection roller 9 arranged side by side. In order to avoid damaging the battery shell, the outer surface of the first detection roller 26 and the outer surface of the second detection roller 9 are both provided with a plastic film. A detection gap 27 is formed between the first detection roller 26 and the second detection roller 9. A pressing strip 10 is provided above the detection gap 27. In order to avoid damaging the battery shell, the pressing strip 10 adopts a plastic strip. The pressing strip 10 is supported by 5 fixed blocks 11. The lower end of the fixed block 11 is fixed to the upper end of the receiving box 8. The upper end of the detection roller group is a feeding end, that is, Figure 1 The left end of the middle detection roller group is the feeding end, and the lower end of the detection roller group is the discharging end. Figure 1 The right end of the middle detection roller group is the discharge end, and the discharge end of the detection roller group is connected to a discharge conveyor line (not shown in the figure). The pressure strip 10 is provided with a guide slope on one side of the feed end of the detection roller group, and a feed pipe 12 is provided above the detection gap 27 at the feed end of the detection roller group. The feed pipe 12 is connected to the discharge channel 24. The rotation direction of the second detection roller 9 is opposite to that of the first detection roller 26, and the rotation direction of the upper half of the second detection roller 9 and the upper half of the first detection roller 26 are both from outside to inside.

[0030] Specifically, the driving device includes a motor 13, a driving pulley 14 is connected to the output shaft of the motor 13, a driven pulley 15 is connected to the first detection roller 26, the driving pulley 14 is connected to the driven pulley 15 through a belt 16, a transmission gear 17 is connected to the second detection roller 9, and a driving gear meshing with the transmission gear 17 is connected to the first detection roller 26.

[0031] It is worth mentioning that, in the present embodiment, although the detection tube 3 is arranged horizontally, and the battery shell is driven to move in the detection tube 3 by the air nozzle, the present invention is not limited thereto, and the detection tube 3 may also be arranged tilted so that the battery shell can slide freely, and then the air nozzle can be eliminated to achieve the purpose of saving costs. However, the structural mode of the tilted arrangement of the detection tube 3 has high requirements on the installation accuracy of the detection block 6, and it is necessary to accurately ensure that the detection channel 25, the feed channel 22, and the discharge channel 24 are in a straight line. Therefore, in actual use, the tilted arrangement of the detection tube 3 is prone to material jamming, and it is easy to mistakenly detect qualified products as unqualified products, and its detection accuracy is relatively poor. Therefore, the present embodiment is a preferred solution.

[0032] During inspection, the battery shell is placed in the vibration disk 1. Under the action of the vibration disk 1, the battery shell is arranged in order and discharged. Under the blowing of the air nozzle, the battery shell enters the inspection tube 3, and the latter battery shell enters the inspection tube 3 and pushes the previous battery shell to move in the inspection tube 3. When the battery shell passes through the inspection block 6, if the outer diameter of the battery shell is too large, it cannot pass through the inspection channel 14, and a jam occurs. At this time, personnel are required to take out unqualified battery shells from the opening 23 of the feed part 19, and sorting can continue. The battery shell passing through the inspection channel 25 falls into the inspection gap 27 of the inspection roller group after passing through the discharge channel 24 and the feed tube 12. If the outer diameter of the battery shell is too small, the battery shell will fall downward from the inspection gap 27 into the receiving box 8. Due to the inclined arrangement of the inspection roller group, qualified products will slide downward to the discharge conveyor line to realize discharge, that is, the entire inspection and sorting process is completed. The operation is convenient and simple, which greatly improves the inspection and sorting efficiency and reduces labor intensity.

[0033] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may be subjected to various changes and modifications, which are within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims.
