[0028] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0029] like Figure 1 and Figure 2 As shown, in one embodiment, a rolling mechanism 10 is provided for scanning a cylindrical battery 20, comprising a frame 100, a rolling assembly 200 and a driving assembly 300. There are at least two rolling assemblies 200, each of which is rotatably arranged on the frame 100 along a preset direction, so that two adjacent rolling assemblies 200 can cooperate to hold the middle position of the cylindrical battery 20. The driving assembly 300 is transmission-connected to each rolling assembly 200, and is used to drive all rolling assemblies 200 to rotate in the same direction.

[0030] When the rolling assembly 200 in the above embodiment is used, the cylindrical battery 20 is placed between two adjacent rolling assemblies 200, so that the two adjacent rolling assemblies 200 cooperate to hold the middle position of the cylindrical battery 20, and then the driving assembly 300 is started to drive the rolling assembly 200 to rotate, and the rolling assembly 200 drives the cylindrical battery 20 to rotate through friction so as to be able to scan the code. Compared with the scanning method in the prior art, the present application uses two adjacent rolling assemblies 200 to hold the middle position of the cylindrical battery 20, without being restricted by the environment at both ends of the cylindrical battery 20, that is, when the two ends of the cylindrical battery 20 cannot be released and blocked, the rolling mechanism 10 can also be used to drive the cylindrical battery 20 to rotate for scanning, thereby improving the adaptability of the rolling mechanism 10.

[0031] The preset direction may be a straight line direction or a curved line direction. The number of rolling components 200 may be flexibly adjusted according to actual use needs. Specifically, in this embodiment, the number of rolling components 200 is at least two, and the rotation axes of the rolling components 200 are located in the same horizontal plane and are spaced apart along the straight line direction.

[0032] Among them, two adjacent rolling assemblies 200 can cooperate to support the middle position of the cylindrical battery 20, which means that the two rolling assemblies 200 can cooperate to support the middle area of ​​the outer wall of the cylindrical battery 20, and the two rolling assemblies 200 are not in contact with both ends of the outer wall of the cylindrical battery 20; in other words, along the axial direction of the rolling assembly 200, the length of the surface of the rolling assembly 200 that is used to contact the cylindrical battery 20 is less than the length of the cylindrical battery 20, so that when the cylindrical battery 20 is placed between two adjacent rolling assemblies 200, the two ends of the cylindrical battery 20 are suspended.

[0033] like Figure 2 and Figure 3 As shown, further, the rolling assembly 200 includes a rotating shaft 210, a roller 220 and a transmission member, the rotating shaft 210 is rotatably connected to the frame 100, the roller 220 and the transmission member are both sleeved on the rotating shaft 210, and the driving assembly 300 is in transmission connection with the transmission member, so that the transmission member can drive all the rollers 220 to rotate synchronously. In this way, the driving assembly 300 can drive the roller 220 to rotate through the transmission member and the rotating shaft 210, and the rotation of the roller 220 drives the corresponding cylindrical battery 20 to rotate through friction so that the code can be scanned.

[0034] like Figure 2 and Figure 3 As shown, optionally, each rolling assembly 200 has at least two rollers 220, and all rollers 220 are sleeved on the rotating shaft 210 and are respectively located on both sides of the transmission member. In this way, by increasing the number of rollers 220, the contact area between the rollers 220 and the cylindrical battery 20 is increased, ensuring that the rolling assembly 200 can drive the cylindrical battery 20 to rotate, and improving the reliability of the rolling mechanism 10.

[0035] Among them, the number of rollers 220 can be flexibly adjusted according to the needs of actual use. Specifically in this embodiment, the roller 220 can be set as a rubber-coated roller to increase the friction between the rolling component 200 and the cylindrical battery 20. The number of rollers 220 is two, and the two rollers 220 are respectively located at both ends of the transmission member, and along the axial direction of the rotating shaft 210, the distance between the two rollers 220 away from each other is less than the length of the cylindrical battery 20. In this way, it is ensured that the roller 220 supports the middle position of the cylindrical battery 20 and does not interfere with the two ends of the cylindrical battery 20.

[0036] like Figure 1 , Figure 2 and Figure 3As shown, in one embodiment, the transmission member is set as a synchronous wheel 230, the diameter of the synchronous wheel 230 is less than or equal to the diameter of the roller 220, the driving assembly 300 includes a motor 310, a driving wheel 320 and a synchronous belt 330, the motor 310 is provided with an output shaft, the driving wheel 320 is sleeved on the output shaft and is located below the synchronous wheel 230, and the synchronous belt 330 is sleeved on the outer side wall of the driving wheel 320 and the outer side wall of each synchronous wheel 230. In this way, the motor 310 can drive the synchronous belt 330 to move through the driving wheel 320, the synchronous belt 330 drives the roller 220 to rotate through the synchronous wheel 230 and the rotating shaft 210, and the roller 220 drives the cylindrical battery 20 to rotate through friction so as to scan the code.

[0037] like Figure 2 and Figure 3 As shown, further, the outer side wall of the synchronous wheel 230 is provided with a first annular groove 231, and the synchronous belt 330 is sleeved on the bottom wall of the first annular groove 231. In this way, the inner side wall of the first annular groove 231 can limit the synchronous belt 330, ensuring that the synchronous belt 330 will not slip off the synchronous wheel 230, thereby improving the reliability of the rolling assembly 200.

[0038] like Figure 2 and Figure 3 As shown, optionally, the bottom wall of the first annular groove 231 is provided with a first tooth portion 232 arranged along the circumference of the synchronous wheel 230, and the inner side wall of the synchronous belt 330 is provided with a second tooth portion arranged along the extension direction of the synchronous belt 330, and the first tooth portion 232 is meshed with the second tooth portion. In this way, the synchronous belt 330 and the synchronous wheel 230 are meshed through the tooth structure, so that the synchronous belt 330 will not slip relative to the synchronous wheel 230 during the movement, ensuring that the roller 220 can drive the cylindrical battery 20 to rotate at a uniform speed, thereby improving the reliability of the rolling mechanism 10.

[0039] Specifically in this embodiment, the first tooth portion 232 can be configured as a tooth groove, and the second tooth portion is correspondingly configured as a gear tooth, and the gear tooth is disposed on the entire inner side wall of the synchronous belt 330 .

In this way, the inner side wall of the second annular groove 321 can limit the synchronous belt 330, ensuring that the synchronous belt 330 will not slip off the driving wheel 320, thereby improving the reliability of the rolling assembly 200. In addition, the synchronous belt 330 and the driving wheel 320 are meshed through the tooth structure, so that the synchronous belt 330 will not slip relative to the driving wheel 320 during the movement, ensuring that the motor 310 can drive the synchronous belt 330 to move at a uniform speed through the driving wheel 320, thereby improving the reliability of the rolling mechanism 10.

[0041] like Figure 2 As shown, in one embodiment, the driving assembly 300 further includes a first tensioning wheel 340, which is disposed below two adjacent synchronous wheels 230, and the first tensioning wheel 340 is rotatably disposed on the frame 100, and is tensioned with the outer wall of the synchronous belt 330. In this way, the first tensioning wheel 340 can tension the synchronous belt 330 between two adjacent synchronous wheels 230, ensuring that the synchronous belt 330 can be closely attached to the outer wall of the synchronous wheel 230, thereby improving the reliability of the rolling mechanism 10.

[0042] like Figure 2 As shown, optionally, the driving assembly 300 further includes a second tensioning wheel 350, which is located between the driving wheel 320 and the outermost synchronous wheel 230, and the second tensioning wheel 350 is rotatably arranged on the frame 100, and is tensioned with the outer wall of the synchronous belt 330. In this way, the second tensioning wheel 350 can tension the synchronous belt 330 between the synchronous wheel 230 and the driving wheel 320, ensuring that the synchronous belt 330 can be closely attached to the outer wall of the synchronous wheel 230 and the outer wall of the driving wheel 320, thereby improving the reliability of the rolling mechanism 10.

[0043] like Figure 2 As shown, optionally, the driving assembly 300 further includes a third tensioning wheel 360, which is located between the driving wheel 320 and the outermost synchronous wheel 230, and the third tensioning wheel 360 is rotatably arranged on the frame 100, and is tensioned with the inner side wall of the synchronous belt 330. In this way, the third tensioning wheel 360 can tension the synchronous belt 330 between the synchronous wheel 230 and the driving wheel 320, ensuring that the synchronous belt 330 can be closely attached to the outer side wall of the synchronous wheel 230 and the outer side wall of the driving wheel 320, thereby improving the reliability of the rolling mechanism 10.

[0044] The number of the first tension wheel 340, the second tension wheel 350 and the third tension wheel 360 can be flexibly adjusted according to the actual use needs. Specifically in this embodiment, there are two second tension wheels 350 and three third tension wheels 360, and along the extension direction of the synchronous belt 330, an outermost synchronous wheel 230, a third tension wheel 360, a second tension wheel 350, a driving wheel 320, another second tension wheel 350, another third tension wheel 360, and another outermost synchronous wheel 230 are arranged in sequence.

Compared with the code scanning method in the prior art, the present application uses two adjacent rolling assemblies 200 to hold the middle position of the cylindrical battery 20, without being restricted by the environment at both ends of the cylindrical battery 20, that is, when the two ends of the cylindrical battery 20 cannot be released and blocked, the rolling mechanism 10 can also be used to drive the cylindrical battery 20 to rotate for code scanning, thereby improving the adaptability of the cylindrical battery code scanning device.

[0047] The code scanning mechanism can be any structure capable of scanning codes in the prior art.
