[0002] Cylindrical batteries, especially cylindrical lithium-ion batteries, are a commonly used type of battery at present and are widely used in products such as laptops and power tools. Generally, a cylindrical battery consists of two parts: a casing and a battery cell. The battery cell is a cylindrical structure produced by an automatic winding device. During the winding process, the roundness of the cylindrical battery cell often becomes poor, resulting in its inability to be automatically inserted into the battery casing. Instead, manual adjustment is required before manually inserting it into the battery casing. This not only results in a poor roundness adjustment effect but also reduces production efficiency. Therefore, it is necessary to adjust the roundness of the cylindrical battery cell. The traditional method is to set an active wheel above the cylindrical battery cell and two fixed wheels below it. However, this method causes the contact area between the wheels and the battery cell to be small during the rolling process of the cylindrical battery cell, and the force is uneven, resulting in an unsatisfactory roundness of the adjusted battery cell and making it difficult to automatically insert it into the casing. Content of the Utility Model

[0003] The purpose of the present invention is to provide a new device for adjusting the roundness of a cylindrical battery cell to address the drawbacks of traditional devices for adjusting the roundness of cylindrical battery cells. It has a simple structure, is not only applicable to cylindrical battery cells of various different diameter sizes, but also has an ideal roundness after adjustment, enabling automatic insertion into the casing and improving production efficiency.

Along both axial sides of the fixed wheel, there are first baffles, and the first baffles are fixed to the bracket. Below the fixed wheel, there are two active wheels with the same axis. The active wheels are installed on a cylinder bracket, and a cylinder that drives upward is provided below the cylinder bracket. On both axial sides of the active wheels, there are second baffles, and the driving rod of a motor passes through the second baffle and is connected to the active wheel.

[0008] In the above device for adjusting the roundness of a cylindrical battery cell, the fixed wheel is made of steel, and the two active wheels below are made of rubber.

[0009] For the above cylindrical battery cell roundness adjustment device, the material of the fixed wheel is steel, and the motor rotation frequencies of the two driving wheels are the same.

In addition, the lifting heights of the two driving wheels are the same.

[0011] In the present utility model, the contact area between the cylindrical battery cell and one upper fixed wheel and two lower driving wheels is large, and the force is more balanced.

[0017] See Figure 1, this embodiment provides a device for adjusting the roundness of a cylindrical battery cell, mainly including a fixed wheel 101 above and two driving wheels 104 below. The fixed wheel 101 above is fixed on the bracket 102 above it, and first baffles 105 are provided on both axial sides of the fixed wheel 101. The two driving wheels 104 below are installed on the cylinder bracket connected to a cylinder 107 below. Under the action of the cylinder 107, this cylinder bracket can drive the driving wheels 104 to lift and lower in the vertical direction. Second baffles 111 are provided on both axial sides of the driving wheels 104. Among them, a motor 108 is provided outside the second baffle 111 on one side of the driving wheel 104, and this motor 108 drives the driving wheel 104 to roll in a direction perpendicular to the axis of the battery cell 103; the distance between the driving wheels 104 can be adjusted by a precision screw 106; when the fixed wheel 101 above remains stationary, the two driving wheels 104 below rise to the set position under the push of the cylinder 107, and the cylindrical battery cell 103 is driven to roll and rotate 360 degrees by the rotation of the two driving wheels 104, thereby realizing the adjustment of the roundness of the cylindrical battery cell 103.

[0018] During use, according to the model and size of the cylindrical battery cell 103, the distance between the two driving wheels 104 is adjusted by the precision screw 106, and at the same time, the lifting height of the cylinder bracket connected to the two driving wheels 104 below and the cylinder 107 is set. Specifically, it can be adjusted in real time according to the actual use situation. A numerical value is preset for the rotation frequency of the motor 108. The transfer device 110 sends the cylindrical battery cell 103 to the initial station, and the robotic arm 109 picks up the battery cell 103 and sends it between the two driving wheels 104; the cylinder 107 is connected to the power supply and the air source, the motor 108 is started. After the cylinder 107 pushes the cylinder bracket together with the two driving wheels 104 to rise to the preset height, the two driving wheels 104 start to rotate 360 degrees under the drive of the motor 108. The cylindrical battery cell 103 is synchronously rolled and rotated 360 degrees under the contact drive between one fixed wheel 101 above and two driving wheels 104 below; then the motor 108 stops working, the two driving wheels 104 stop rotating, the cylinder 107 drives the cylinder bracket connected to the two driving wheels 104 to descend, and it is picked up by the robotic arm 109 and sent to the next station. At this time, the roundness adjustment work of the cylindrical battery cell 103 is completed.

[0019] Specifically, the material of the fixed wheel 101 above the device is steel, and the material of the two driving wheels 104 below is rubber.

[0020] Specifically, according to the different sizes of the cylindrical battery cell 103, the distance between the two driving wheels 104 below is adjustable, and the vertical lifting height of the cylinder bracket connecting the two driving wheels 104 and the cylinder 107 can also be adjusted accordingly, which is applicable to cylindrical battery cells of various different specifications and sizes. In addition, the lifting heights of the two driving wheels 104 are the same.

[0021] Specifically, the two motors 108 connected to the two driving wheels 104 are set to have the same rotation frequency.
