[0036] Researchers have discovered that during the process of stacking multiple cells of a battery pack, the positioning blocks and positioning pins of the stacking equipment are usually debugged manually. Manual debugging is difficult to meet the accuracy requirements and is time-consuming and labor-intensive.

[0037] In order to solve the above technical problem, an embodiment of the present application provides a debugging device for debugging and positioning a positioning block in a stacking device.

[0038] Reference Figure 1 , Figure 2 as well as Figure 5 As shown, the debugging device includes: a positioning member 100 and a plurality of limit assemblies 200 .

[0039] Specifically, positioning holes 110 are provided at both ends of the positioning member 100 along the length direction x; a plurality of limiting components 200 are arranged on the positioning member 100 at intervals along the length direction x, and a positioning space 210 is formed in each limiting component 200, and the positioning space 210 is used to fix the positioning block 300, and a plurality of positioning spaces 210 are located between the positioning holes 110 at both ends of the positioning member 100.

[0040] It should be noted that the length direction x is Figure 1 The direction that x points to.

[0041] In the debugging device provided in this embodiment, multiple limit assemblies 200 are arranged on the positioning member 100 at intervals along the length direction x. At the same time, since each limit assemblies 200 has a positioning space 210 formed therein, the positioning block 300 in the stacking device can be placed in the positioning space 210 of each limit assemblies 200, so that each positioning block 300 can be positioned through each positioning space 210. In this way, the multiple positioning blocks 300 in the stacking device can be debugged through the limit assemblies 200. Further, the positioning pin 400 in the stacking device can be inserted into the positioning hole 110 of the positioning member 100 to achieve the positioning of the positioning pin 400. In this way, the stacking device can be quickly debugged through the above debugging device, meeting the accuracy requirements and saving manpower. So that the stacking device can meet the accuracy requirements, thereby improving the accuracy of CTP battery pack stacking.

[0042] Reference Figure 2 As shown, in some embodiments, each limiting assembly 200 includes a first limiting member 220 and a second limiting member 230 . The first limiting member 220 and the second limiting member 230 are spaced apart along the length direction x and enclose the positioning member 100 to form a positioning space 210 .

[0043] In this embodiment, in each limiting assembly 200, since the first limiting member 220 and the second limiting member 230 are spaced apart along the length direction x to form a positioning space 210, the positioning block 300 can be limited in the length direction x by the first limiting member 220 and the second limiting member 230 to determine the position of the positioning block 300, and the positioning block 300 is further debugged to determine the relative position relationship between the multiple positioning blocks 300, so that the relative position relationship between the positioning blocks 300 satisfies the relative position relationship between the multiple battery cells, so as to achieve accurate stacking of the battery cells.

[0044] Reference Figure 3 As shown, in some embodiments, the positioning member 100 has a first plane 120 and a second plane 130 arranged opposite to each other along the thickness direction y, and a plurality of limiting components 200 are arranged on the first plane 120 along the thickness direction y; wherein the thickness direction y is perpendicular to the length direction x.

[0045] It should be noted that the thickness direction y is Figure 3 The direction that y points to.

[0046] In this embodiment, when debugging multiple positioning blocks 300, multiple limit assemblies 200 arranged on the first plane 120 can be oriented toward the multiple positioning blocks 300, and each positioning block 300 can be positioned by the first limit member 220 and the second limit member 230 of each limit member 200. In this process, the positioning block 300 can be embedded in the positioning space 210 by pressing the second plane 130 arranged opposite to the first plane 120 along the thickness direction y, so as to realize the debugging of the above-mentioned debugging device and the positioning block 300 of the stacking device.

[0047] Reference Figure 2 As shown, the first plane 120 has a plurality of inclined surfaces 1200 connected in sequence, each inclined surface 1200 is set at an angle with the length direction x, and the plurality of inclined surfaces 1200 are arranged along the length direction x. In each limiting assembly 200, the first limiting member 220 and the second limiting member 230 are respectively located at the two ends of an inclined surface 1200 along the length direction x.

[0048] In this embodiment, when the positioning block 300 is located in a positioning space 210, one of the surfaces of the positioning block 300 is in close contact with the inclined surface 1200 at the positioning space 210. Therefore, the positioning block 300 can be positioned along the thickness direction y through the inclined surface 1200. At the same time, the positioning block 300 can also be positioned along the length direction x through the first limit member 220 and the second limit member 230. In this way, the positioning block 300 can be positioned along the length direction x and the thickness direction y at the same time to ensure the debugging accuracy and convenience of the positioning block 300.

[0049] Reference Figure 3 As shown, in some embodiments, among any two adjacent inclined surfaces 1200 , the lowest point of one inclined surface 1200 is set close to the lowest point of the other inclined surface 1200 , or the highest point of one inclined surface 1200 is set close to the highest point of the other inclined surface 1200 .

[0050] In the present embodiment, since each inclined surface 1200 is set at an angle with the length direction x, each positioning block 300 can be set at an angle with the length direction x. Furthermore, in any two adjacent inclined surfaces 1200, since the lowest point of one of the inclined surfaces 1200 is set close to the lowest point of the other inclined surface 1200, or the highest point of one of the inclined surfaces 1200 is set close to the highest point of the other inclined surface 1200, it is possible to set two adjacent positioning blocks 300 at an angle so that the multiple positioning blocks 300 form a bent extrusion surface, so that the multiple battery cells squeezed and stacked by the multiple positioning blocks 300 can form a bent stack shape, so that the stacking of the battery cells can adapt to the shape of the shell, so as to improve the compatibility between the battery cells and the shell, and there is no need to design a shell that is suitable for the size of the battery cells.

[0051] The highest points of the two outermost inclined surfaces 1200 along the length direction x are close to the positioning hole 110. This arrangement can improve the overall structural strength of the debugging device.

[0052] Reference Figure 5 As shown, in some embodiments, in each limit assembly 200, the dimensions of the first limit member 220 and the second limit member 230 along the direction perpendicular to the inclined surface 1200 are smaller than the thickness of the positioning block 300. In this way, the limiting performance of the first limit member 220 and the second limit member 230 on the positioning block 300 along the length direction x can be ensured, and the contact between the positioning block 300 and the inclined surface 1200 can be ensured, so as to improve the debugging accuracy of the positioning block 300.

[0053] Reference Figure 3 as well as Figure 4 As shown, in some embodiments, in the same limiting component 200 arranged on the inclined surface 1200, the first limiting member 220 and the second limiting member 230 are arranged in parallel, and in any two adjacent limiting components 200, the adjacent first limiting members 220 and the second limiting members 230 are arranged at an angle.

[0054] It should be noted that, generally speaking, the positioning block 300 of the stacking device is a rectangular parallelepiped or cube structure, and the specific shape is not limited as long as its shape matches the shape of the battery cell.

[0055] In this embodiment, in the same limit assembly 200, since the first limit member 220 and the second limit member 230 are arranged in parallel, the positioning block 300 can be in contact with the first limit member 220 and the second limit member 230 on both sides along the length direction x, respectively, so as to improve the limiting effect of the limit assembly 200 on the positioning block 300. Furthermore, in any two adjacent limit assemblies 200, since the first limit member 220 and the second limit member 230 are arranged at an angle, the two adjacent inclined surfaces 1200 can be arranged at an angle, so that the multiple positioning blocks 300 debugged by the above-mentioned debugging device can meet the angle requirements of battery cell stacking.

[0056] Reference Figure 3 As shown, in some embodiments, the outer surface of the second plane 130 facing away from the first plane 120 is parallel to the length direction x.

[0057] In this embodiment, since the outer surface of the second plane 130 facing away from the first plane 120 is parallel to the length direction x, when the second plane 130 is pressed, each first limiting member 220, second limiting member 230 and inclined surface 1200 located on the first plane 120 can be offset against the corresponding positioning block 300, so as to improve the uniformity of the force applied by the positioning member 100 and the limiting assembly 200 to each positioning block 300, thereby improving the debugging accuracy of the multiple positioning blocks 300 to ensure that the relative position relationship between the positioning blocks 300 meets the stacking requirements of the battery cells.

[0058] Reference Figure 5 As shown, in some embodiments, in each limiting assembly 200 , the first limiting member 220 and the second limiting member 230 are used to be interference fit with the positioning block 300 .

[0059] In this embodiment, since the first limit member 220 and the second limit member 230 are both used for interference fit with the positioning block 300, when the positioning block 300 is located in a positioning space 210, the first limit member 220 and the second limit member 230 located on both sides of the positioning block 300 along the length direction x can be offset from the positioning block 300, thereby improving the limiting effect of the first limit member 220 and the second limit member 230 on the positioning block 300, and at the same time making the distance between the first limit member 220 and the second limit member 230 consistent with the length of the positioning block 300, so as to achieve precise debugging of the positioning block 300.

[0060] Reference Figure 2As shown, in some embodiments, in any two adjacent limiting assemblies 200, the first limiting member 220 of one limiting assembly 200 is spaced from the second limiting member 230 of the other limiting assembly 200 to define an escape space 240. That is, an escape space 240 is defined between the adjacent first limiting member 220 and the second limiting member 230.

[0061] In this embodiment, in any two adjacent limit assemblies 200, since the first limit member 220 of one of the limit assemblies 200 is spaced apart from the second limit member 230 of the other limit assembly 200, the distance between any two adjacent positioning blocks 300 can be limited by the avoidance space 240 located between the two adjacent limit assemblies 200, so that the distance between the two adjacent positioning blocks 300 meets the distance requirement between any two adjacent battery cells.

[0062] The length of the avoidance space 240 along the length direction x is: 2mm≤L 2 ≤10mm, so that deformation space can be reserved for the first limiting member 220 and the second limiting member 230.

[0063] Reference Figure 1 As shown, in some embodiments, a positioning hole 110 is provided at each end of the positioning member 100 along the length direction x, the two positioning holes 110 are both extended along the thickness direction y, and the centers of the two positioning holes 110 are located on the same straight line along the length direction x.

[0064] In this embodiment, since the two positioning holes 110 are both extended along the thickness direction y, when each positioning pin 400 is inserted into a positioning hole 110, the parallelism between the two positioning pins 400 can be ensured to ensure the position consistency between the two positioning pins 400. At the same time, since the central axes of the two positioning holes 110 are located on the same straight line along the length direction x, the position consistency of the two positioning pins 400 can be further improved, so as to improve the positioning accuracy of the stacking equipment for the cooling water pipes of the battery cell group.

[0065] Reference Figure 1 As shown, in some embodiments, in the thickness direction y, one ends of the two positioning holes 110 are located on the same horizontal plane, and the other ends of the two positioning holes 110 are located on the same horizontal plane.

[0066] In this embodiment, in the thickness direction y, since one end of the two positioning holes 110 is located on the same horizontal plane, and the other ends of the two positioning holes 110 are located on the same horizontal plane, when the two positioning pins 400 are debugged through the two positioning holes 110, it can be ensured that the position and depth of the two positioning pins 400 passing through the positioning holes 110 remain consistent, thereby ensuring that the debugging effect of the two positioning holes 110 on the two positioning pins 400 is consistent, and further ensuring the debugging accuracy of the two positioning holes 110 on the two positioning pins 400.

[0067] Specifically, in some embodiments, each positioning hole 110 is used for interference fit with the positioning pin 400 .

[0068] In this embodiment, since each positioning hole 110 is used for interference fit with the positioning pin 400, when the positioning pin 400 is inserted into a positioning hole 110, the debugging accuracy of the positioning hole 110 for the positioning pin 400 can be improved, thereby improving the stacking accuracy of the stacking equipment for the battery pack.

[0069] After the end of the positioning pin 400 is inserted into a positioning hole 110, the positioning pin 400 can be positioned. The positioned positioning pin 400 can be inserted into the cooling water pipe of the cooling plate to position the cooling water pipe.

[0070] Reference Figure 1 as well as Figure 5 As shown, in some embodiments, the number of the limiting components 200 is n, satisfying: 3≤n≤8.

[0071] Specifically, n can be 3, 5, 6, 8, etc.

[0072] In the present embodiment, the number of the limiting components 200 is determined by the number of the positioning blocks 300, and the number of the positioning blocks 300 is determined by the number of cells in the battery pack. For example, when the number of cells is 2, the number of the positioning blocks 300 is 2, and n=2 at this time; when the number of cells is 3, the number of the positioning blocks 300 is 2, and n=3 at this time; when the number of cells is 5, the number of the positioning blocks 300 is 5, and n=5 at this time; if n<3, it means that the number of cells in the battery pack is less than 3. At this time, the capacity of the battery pack will be greatly reduced and cannot meet the large capacity demand; if n>8, it means that the number of cells in the battery pack is greater than 8. At this time, the excessive number of cells in the battery pack will increase the difficulty of stacking the battery pack, and further reduce the stacking accuracy; when 3≤n≤8, both the capacity of the battery pack and the stacking accuracy of the battery pack can be improved.
