Description

Technical Field

[0002] In the manufacturing process of battery modules, cell stacking is one of the key technological steps, and its quality directly affects the overall performance, safety, and assembly accuracy of the battery module. Currently, some production lines still use manual methods for cell stacking, where operators place individual cells sequentially in designated positions and align and secure them.

[0003] However, this traditional manual stacking method has many shortcomings: manual stacking is inefficient and cannot meet the needs of large-scale, high-speed production lines. Since each cell stacking requires manual positioning and adjustment, the number of cells stacked per unit time is limited, thus restricting the overall production cycle. Secondly, manual operation is prone to causing unstable stacking quality, resulting in problems such as misalignment, tilting, or uneven gaps, which in turn affects the quality consistency of subsequent packaging and connection processes.

[0025] In the manufacturing process of battery modules, cell stacking is one of the key technological steps, and its quality directly affects the overall performance, safety, and assembly accuracy of the battery module. Currently, some production lines still use manual methods for cell stacking, where operators place individual cells sequentially in designated positions and align and secure them.

[0026] However, this traditional manual stacking method has many shortcomings: manual stacking is inefficient and cannot meet the needs of large-scale, high-speed production lines. Since each cell stacking requires manual positioning and adjustment, the number of cells stacked per unit time is limited, thus restricting the overall production cycle. Secondly, manual operation is prone to causing unstable stacking quality, resulting in problems such as misalignment, tilting, or uneven gaps, which in turn affects the quality consistency of subsequent packaging and connection processes.

[0027] Based on the problems existing in the current technology, please refer to Figures 1 to 4 This utility model provides a battery cell assembly fixture 10, which includes a battery cell stacking device 100 and a clamping device 200. The battery cell stacking device 100 enables automated battery cell stacking operations. After stacking, the clamping device 200 transfers the battery cells to the battery box, thereby meeting the needs of efficient, high-quality, and automated production, significantly improving the production efficiency and product consistency of battery modules, and meeting the actual needs of industrial development.

[0028] In detail, the cell stacking device 100 includes a mounting base 110, a first stacking mechanism 120, and a second stacking mechanism 130.

[0029] The mounting base 110 is used to place the battery cell; the first stacking mechanism 120 includes a first driving member 121 and a first limiting member 122, which are disposed opposite to each other on the mounting base 110. The output end of the first driving member 121 can move along a first direction to push the battery cell to abut against the first limiting member 122; the second stacking mechanism 130 includes a second driving member 131 and a second limiting member 132, which are disposed opposite to each other on the mounting base 110. The output end of the second driving member 131 can move along a second direction to push the battery cell to abut against the second limiting member 132.

[0030] First, it should be noted that the first direction is the X direction shown in the figure, and the second direction is the Y direction shown in the figure. The first direction and the second direction are set at an angle, so that the first driving member 121 pushes the battery cell from the first direction and the second driving member 131 pushes the battery cell from the second direction. Therefore, multiple battery cells are tightly stacked along the first direction under the squeezing action of the first driving member 121 and the first limiting member 122, and tightly stacked along the second direction under the squeezing action of the second driving member 131 and the second limiting member 132. This not only can the automatic stacking of battery cells be realized efficiently, but also the consistency of battery cell stacking can be guaranteed, thus significantly improving the production efficiency and product consistency of battery modules.

[0031] It is understood that the first and second directions can be set according to the shape requirements of the battery module. For example, as shown in the figure, the battery cells are arranged in an array. Therefore, in order to ensure that multiple battery cells are stacked tightly, the first and second directions in this embodiment are perpendicular to each other on the horizontal plane. Of course, in other embodiments of this utility model, the first and second directions can also be set at other angles, such as 85°, 95°, etc., which are not specifically limited here.

[0032] Specifically, the first driving member 121 includes a first mounting member 1211, a first transmission rod 1212, and a first pushing member 1213. The first mounting member 1211 is disposed on the mounting base 110, and the first transmission rod 1212 is movably disposed on the first mounting member 1211. The first transmission rod 1212 is in transmission cooperation with the first pushing member 1213 to drive the first pushing member 1213 to move along a first direction.

[0033] In this embodiment, one end of the first transmission rod 1212 is movably connected to the first mounting member 1211, and the other end is correspondingly provided with the first limiting member 122. The first transmission rod 1212 and the first pushing member 1213 are in a lead screw engagement. That is, by rotating the first transmission rod 1212, the first pushing member 1213 can be driven to move along the extension direction of the first transmission rod 1212, thereby driving the first pushing member 1213 to move toward or away from the first limiting member 122, so that the battery cells are tightly stacked.

[0034] Optionally, a ratchet wrench can be used to drive the first transmission rod 1212 to rotate. Of course, in other embodiments of this utility model, other driving directions can also be used, which are not specifically limited here.

[0035] It is worth mentioning that the mounting base 110 is provided with at least two support parts 111, and the at least two support parts 111 are arranged at intervals. The support parts 111 are used to place the battery cells, and the first transmission rod 1212 is arranged between two adjacent support parts 111.

[0036] In this embodiment, there are two support parts 111, that is, multiple battery cells are supported by two support parts 111. Of course, in other embodiments of this utility model, the number of support parts 111 can be other numbers, which are not specifically limited here.

[0037] Specifically, the second driving member 131 includes a second mounting member 1311, a second transmission rod 1312, and a second pushing member 1313. The second mounting member 1311 is disposed on the mounting base 110, and the second transmission rod 1312 is movably disposed on the second mounting member 1311. The second transmission rod 1312 is connected to the second pushing member 1313 and is used to drive the second pushing member 1313 to move in a second direction.

[0038] In this embodiment, the second transmission rod 1312 can be threadedly engaged with the second mounting member 1311. Therefore, by turning the second transmission rod 1312, the second push member 1313 can be driven to move toward or away from the second limiting member 132, thereby achieving the purpose of squeezing the battery cell.

[0039] Optionally, a ratchet wrench can be used to drive the second transmission rod 1312 to rotate. Of course, in other embodiments of this utility model, other driving directions can also be used, which are not specifically limited here.

[0040] Furthermore, the first stacking mechanism 120 also includes a pressure sensor 123, which is disposed on the first limiting member 122.

[0041] In this embodiment, a pressure sensor 123 is provided at the first limiting member 122 so that the pressure sensor 123 can obtain the squeezing force in real time when the first driving member 121 squeezes the battery cell, thereby avoiding excessive squeezing force of the first driving member 121 that could damage the battery cell.

[0042] It is understood that the pressure sensor 123 can also be set at the second limiting member 132, or simultaneously set at the first limiting member 122 and the second limiting member 132. It can be set according to actual needs, and no specific limitation is made here.

[0043] Furthermore, the cell stacking device 100 also includes a vehicle body 140, and a mounting base 110 is disposed on the vehicle body 140.

[0044] In this embodiment, by placing the mounting base 110 on the vehicle body 140, it is convenient for the operator to push the vehicle body 140 after the battery cells are stacked at the stacking station, so as to transfer the stacked battery cells to the clamping and boxing station, thereby improving the work efficiency.

[0045] Furthermore, the clamping device 200 includes a support 210 and a clamping mechanism 220. The clamping mechanism 220 is disposed on the support 210 and is used to clamp and transfer the battery cells stacked on the battery cell stacking device 100.

[0046] Specifically, the clamping mechanism 220 includes a third mounting member 221, a third transmission rod 222, a first clamping member 223, and a second clamping member 224. The third mounting member 221 and the second clamping member 224 are disposed opposite to each other on the support base 210. The third transmission rod 222 is movably disposed on the third mounting member 221 and is connected to the first clamping member 223 for driving the first clamping member 223 to move toward or away from the second clamping member 224.

[0047] It should be noted that multiple battery cells are stacked sequentially on the support 111 along the first direction. Therefore, when it is necessary to clamp and transfer the stacked battery cells, the vehicle body 140 needs to be moved to the position corresponding to the first clamping member 223 and the first driving member 121, and the position corresponding to the second clamping member 224 and the first limiting member 122. Thus, under the drive of the third transmission rod 222, the first clamping member 223 is driven to move toward the battery cell and clamp and transfer the battery cell with the second clamping member 224.

[0048] It is understood that the third transmission rod 222 can also be threadedly engaged with the third mounting part 221. Therefore, a ratchet wrench can be used to drive the third transmission rod 222 to rotate. Of course, in other embodiments of this utility model, other driving directions can also be used, which are not specifically limited here.

[0049] It is worth mentioning that, in order to ensure that the first clamping member 223 and the second clamping member 224 can smoothly clamp the battery cell when the first pushing member 1213 and the first limiting member 122 are pressing the battery cell, both the first pushing member 1213 and the first limiting member 122 are provided with clearance grooves, so that the first clamping member 223 can extend into the clearance groove of the first pushing member 1213 and the second clamping member 224 can extend into the clearance groove of the first limiting member 122. After the first clamping member 223 and the second clamping member 224 clamp the battery cell, the first transmission rod 1212 and the second transmission rod 1312 are driven to drive the first pushing member 1213 and the second pushing member 1313 away from the battery cell, so that the battery cell is transferred from the mounting base 110 to the battery box under the clamping action of the first clamping member 223 and the second clamping member 224.

[0050] To further avoid the risk of the battery cell falling during the clamping and transfer process, the clamping device 200 also includes an adsorption element 230, which is disposed on the support base 210 and is used to adsorb the battery cell.

[0051] In this embodiment, the adsorption member 230 can use vacuum adsorption to adsorb the battery cell while the clamping mechanism 220 clamps and transfers the battery cell, thus preventing the battery cell from falling off during the process.

[0052] Furthermore, the clamping device 200 also includes a pushing mechanism 240, which is disposed on the support base 210. The output end of the pushing mechanism 240 is connected to the adsorption member 230 and is used to drive the adsorption member 230 to move along a third direction, which is perpendicular to the plane containing the first direction and the second direction.

[0053] In this embodiment, the third direction is the Z direction as shown in the figure, that is, the vertical direction. After the first clamping member 223 and the second clamping member 224 transfer the battery cell to the battery box, the pushing mechanism 240 pushes the battery cell vertically downward from the first clamping member 223 and the second clamping member 224 into the battery box.

[0054] Optionally, the pushing mechanism 240 can be, but is not limited to, a cylinder. To avoid damaging the battery cell during the pushing process, a sponge suction cup can be used at the adsorption component 230; in addition, a sensor can be set at the adsorption component 230 to determine whether the battery cell is in the box based on the pressure of the adsorption component 230.

[0055] In summary, this utility model provides a cell stacking device 100 and a cell assembly fixture 10. By using a first driving member 121 to push the cell in a first direction and a second driving member 131 to push the cell in a second direction, multiple cells are tightly stacked along the first direction under the squeezing action of the first driving member 121 and the first limiting member 122, and tightly stacked along the second direction under the squeezing action of the second driving member 131 and the second limiting member 132. This not only enables efficient automatic stacking of cells, but also ensures the consistency of cell stacking, thus significantly improving the production efficiency and product consistency of battery modules.

[0056] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
