[0044] As a preferred embodiment in the embodiment, the rotating component 2 in the embodiment includes a turntable 21, a shaft 22 and a first driving member 23, wherein a circular hole is formed in the cabinet 1, and the turntable 21 is rotatably connected in the circular hole through a bearing; the first driving member 23 is arranged in the cabinet 1; the shaft 22 is fixed at the shaft center of the turntable 21, and the end away from the turntable 21 extends into the cabinet 1 and is fixedly connected with the output shaft of the first driving member 23, for driving the turntable 21 to rotate circumferentially.

[0045] It should be noted that the first driving member 23 drives the shaft rod 22 to rotate, and the shaft rod 22 drives the rotating disc 21 to rotate circumferentially in the circular hole of the cabinet 1 through the bearing; the bearing reduces the friction during rotation and ensures that the rotating disc 21 can rotate smoothly; the rotating disc 21 drives the rotating assembly 3 loaded with the cylindrical battery to rotate circumferentially; and the cylindrical battery sequentially passes through the first deviation rectifying assembly 4 and the second deviation rectifying assembly 5 for deviation rectification of the tab.

[0051] It should be noted that when it is necessary to adjust the direction of the tab of the cylindrical battery, the second driving member 32 drives the sleeve 31 to rotate circumferentially in the slot position 20, and since the cylindrical battery is clamped in the sleeve 31, the battery will rotate together with the sleeve 31, thereby achieving adjustment of the direction of the tab.

[0053] It should be noted that when the cylindrical battery is clamped in the sleeve 31 in each slot 20, since the inner diameter of the sleeve 31 matches the diameter of the cylindrical battery, the battery can smoothly extend into the sleeve 31; during the extension process, the battery abuts against the elastic element 33 on the inner wall of the sleeve 31, the elastic element 33 elastically deforms, and an elastic force is generated to elastically fix the cylindrical battery in the sleeve 31, so that the battery cannot be easily loosened or fallen off during subsequent rotation and adjustment.

[0054] Specifically, the elastic element 33 in the embodiment is preferably a rubber elastic element; the elastic deformation capability of the elastic element 33 can adapt to these small size differences, so that cylindrical batteries of different sizes can be well fixed in the sleeve 31, improving the universality and compatibility of the mechanism, and the rubber elastic element can also play a buffering and protection role on the cylindrical battery, avoiding scratching the surface of the shell of the cylindrical battery.

[0062] The first industrial camera 6 and the second industrial camera 7 are arranged on the two sides of the turntable 21 and are arranged in parallel with the clamping jaw 425, which can ensure that consistent image information of the battery tab is obtained from different angles; the first industrial camera 6 shoots a picture of the cylindrical battery, detects whether the angle between the tab and the edge of the shell opening is perpendicular through a pre-trained image recognition algorithm, rectifies the deviation through the first deviation rectifying assembly 4 if it is not perpendicular, rotates the cylindrical battery to the corresponding position of the second deviation rectifying assembly 5 through the rotating assembly 2 if it is perpendicular, and the second deviation rectifying assembly 5 shapes the tab, and the second industrial camera 7 shoots a picture of the cylindrical battery, detects the height value of the tab, and if the measured height is equal to the preset value, it is normally forwarded, otherwise, the rejection mechanism is started to reject the unqualified battery from the production process.

[0065] Working principle:

[0066] Firstly, a plurality of cylindrical batteries are clamped in the sleeves 31 of the rotating assembly 3 corresponding to each slot 20 of the rotating assembly 2, and the elastic members 33 elastically fix the batteries in the sleeves 31, ensuring that the batteries will not be easily loosened or fallen off during subsequent rotation and adjustment;

[0067] Then, the first driving member 23 starts to drive the shaft 22 to rotate, and the shaft 22 drives the rotating disc 21 to rotate circumferentially in the circular hole of the cabinet 1 through the bearing, and the rotating disc 21 drives the rotating assembly 3 loaded with cylindrical batteries to rotate circumferentially, so that the cylindrical batteries pass through the first correction assembly 4 and the second correction assembly 5 in turn;

[0068] When the cylindrical battery rotates to the first correction assembly 4 position with the rotating disc 21, the first industrial camera 6 takes a picture of the cylindrical battery, and through the pre-trained image recognition algorithm, it detects whether the angle of the tab and the edge of the shell opening is perpendicular;

[0069] If the tab is not perpendicular, the second driving member 32 starts to drive the sleeve 31 to rotate circumferentially in the slot 20, so that the battery rotates to adjust the direction of the tab. After the positioning probe 8 on one side detects that the cylindrical battery tab is rotated in place, that is, the tab is perpendicular to the detection end of the positioning probe 8, it is ensured that the tab is located between the two clamping parts 405 of the clamping jaw 425. The extension of the pushing member 415 of the first correction assembly 4 pushes the clamping jaw 425 to move towards the slot 20, and the two clamping parts 405 move relatively close to each other to correct the length direction of the cylindrical battery tab. After the correction is completed, the clamping part 405 rises, the pushing member 415 retracts, the clamping jaw 425 moves away from the slot 20, and the next battery is waiting;

[0070] If the tab is perpendicular or the cylindrical battery after the correction of the first correction assembly 4 continues to rotate with the rotating assembly 2, reaches the second correction assembly 5, and the positioning probe 8 on the other side detects that the cylindrical battery tab is rotated in place, the pushing member 415 of the second correction assembly 5 pushes the clamping jaw 425 to move towards the slot 20, so that the clamping part 405 aligns and clamps the tab of the cylindrical battery. The heating member 501 starts to work, the temperature of the heating cavity 500 rises, and gradually rises to 300℃, achieving the effect of heating and setting the bent tab;

[0071] Subsequently, the heating element 501 stops heating, the second deviation correction assembly 5 resets, the second industrial camera 7 takes a picture of the cylindrical battery, detects the height value of the tab, if the measured height is equal to the preset value, the battery is normally transferred downward; if it does not meet the requirements, the rejection mechanism is started to reject the unqualified battery from the production process.

[0072] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
