[0038] The battery cell correction device provided in this utility model will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0039] Reference Figures 1 to 2This utility model provides a battery cell alignment device, including a fixed plate 1, a first platform 21, a first driving component 3, a second driving component 4, a rotating component 5, and an image detection component 6. The first driving component 3 is disposed on the fixed plate 1, and the second driving component 4 is connected to the first driving component 3. The first driving component 3 translates relative to the fixed plate 1 along a first direction, and the second driving component 4 translates relative to the first driving component 3 along a second direction. The rotating component 5 is connected to the second driving component 4 and rotates relative to the second driving component 4 about a third direction. The first direction and the second direction intersect and form a first plane, and the third direction is not coplanar with the first plane. The first platform 21 is fixed to the rotating component 5, and the image detection component 6 is disposed on the fixed plate 1 and close to the first platform 21. The first platform 21 is used to place the battery cell, and the image detection component 6 is used to detect the position of the battery cell and send the position information to each driving component to correct the position of the battery cell.

[0040] Specifically, such as Figure 1 and Figure 2As shown, the battery cell alignment device includes a fixed plate 1, a first platform 21, a first drive assembly 3, a second drive assembly 4, a rotating assembly 5, and an image detection assembly 6. The fixed plate 1 serves as the reference surface and support structure for the entire device. The image detection assembly 6 is fixed to the fixed plate 1 and located above the first platform 21. The first platform 21 is used to place un-welded battery cells. The image detection assembly 6 detects the position information of the un-welded battery cells, compares it with a preset position, calculates the offset position of the un-welded battery cells, converts the signal into coordinate data, and sends it to each drive assembly, causing each drive assembly to move. It should be noted that the preset position can be referenced to the position of already-welded battery cells. The first drive assembly 3, the second drive assembly 4, and the rotating assembly 5 constitute a drive mechanism mounted on the fixed plate 1. The power input end of the first drive assembly 3 is fixed to the fixed plate 1, and the power output end of the first drive assembly 3 is fixed to the power input end of the second drive assembly 4. Driven by the power input end, the power output end of the first drive assembly 3 moves relative to the fixed plate 1 along a first direction, and drives the second drive assembly 4 and the rotating assembly 5 to move along the first direction. The power output end of the second drive assembly 4, driven by the power input end, moves relative to the first drive assembly 3 along the second direction, and drives the rotating assembly 5 to move along the second direction. The first drive assembly 3 and the second drive assembly 4 are either cylinder drive assemblies or motor drive assemblies. Driven by its own drive component, the rotating assembly 5 rotates relative to the second drive assembly 4 around the third direction (Z), simultaneously driving the first platform 21 to rotate around the third direction. The rotating assembly 5 is a rotating cylinder mechanism or an electric rotating mechanism. The first direction intersects the second direction, forming a certain angle, which can be 60°, 70°, 80°, or 90°. The plane formed by the first direction and the second direction is the first plane. The third direction is not coplanar with the first plane, forming a certain angle with the first plane. In this embodiment, the first direction and the second direction are set to be perpendicular to each other; the first direction is the X-direction, the first direction is the Y-direction, the first plane is the XY plane, and the third direction is perpendicular to the XY plane, i.e., the third direction is the Z-direction. The driving mechanisms of the first driving component 3, the second driving component 4, and the rotating component 5 operate independently of each other, and each is electrically connected to the image detection component 6. That is, the three can work simultaneously or any one of them can work alone, driving the battery cell on the first platform 21 to translate along the X and Y directions and rotate around the Z direction for position compensation.

[0041] In some embodiments, the cell alignment device operates as follows: the image detection component 6 detects the position information of the cell on the first platform 21, compares it with a preset position, calculates the offset distance of the cell, and converts this signal into coordinate data, which is then sent to each drive component. Upon receiving the coordinate data, each drive component generates its own movement. Specifically, the first drive component 3 translates relative to the fixed plate 1 along the first direction X, causing the cell to translate along the X direction; the second drive component 4 translates relative to the first drive component 3 along the second direction Y, causing the cell to translate along the Y direction; and the rotation component 5 rotates relative to the second drive component 4 around a third direction Z, causing the cell to rotate around the Z direction for position compensation, until it is adjusted to a preset position to meet subsequent assembly requirements. Furthermore, this alignment device also includes a handling robot (not shown in the figure), used to adjust the height position of the cell along the Z direction.

[0042] The cell alignment device provided in this embodiment of the invention, through the automated adjustment process of the image detection component and the drive mechanism, avoids the high degree of manual intervention and positioning instability during repeated placement, thereby improving positioning accuracy and production efficiency and ensuring product consistency. Utilizing advanced data-driven and intelligent manufacturing technologies, it promotes the upgrading of battery assembly production lines and increases production capacity.

[0044] Specifically, such as Figure 1 and Figure 2 As shown, the second platform 22 is fixed on the fixed plate 1 and is used to place the second battery cell that has undergone circuit board soldering, while the first platform 21 is used to place the first battery cell that has not undergone circuit board soldering. The image detection component 6 detects the image positions of the first battery cell, the second battery cell, and the circuit board. Then, using the reference edge of the second battery cell as a reference for the movement position of the first battery cell, the position information is sent to each drive component. The first battery cell moves under the drive of each drive component until it moves to a position aligned and close to the second battery cell, thus completing the position compensation and allowing subsequent assembly work to proceed. When a battery cell is temporarily offline due to mid-process issues and needs to be reintroduced into the automated line, the battery cell alignment device provided in this embodiment is used to achieve high-precision adjustment of the battery cell position through translation along the X and Y axes and angle adjustment around the Z axis, thereby improving the efficiency of the re-injection process for paired batteries.

The rotary cylinder of the pressing assembly 8 retracts, and the clamps rotate and descend to clamp and fix the second battery cell.
