[0041] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] Reference Figures 1-6 As shown, an embodiment of the present invention proposes a module stacking tool, comprising a base plate 1, a lifting assembly 2, a connecting plate 3 and a cell support assembly 4, and a reference side positioning assembly 5 and a movable side positioning assembly 6 respectively located on both sides of the cell support assembly 4, wherein:

[0043] The lifting assembly 2 is installed on the base plate 1 and connected to the connecting plate 3;

[0044] The battery cell support assembly 4 is slidably mounted on the connecting plate 3 and has an adjustable length for supporting the battery cell;

[0045] The reference side positioning assembly 5 includes a first positioning block 51 and a first extrusion block 52. The first positioning block 51 is mounted on the cell support assembly 4. A positioning column 511 for plugging the reference side end plate is provided on the top of the first positioning block 51. The first extrusion block 52 is fixedly mounted on the bottom plate 1 and located above the first positioning block 51 to support the side of the reference side end plate.

[0046] The movable side positioning assembly 6 includes a second positioning block 61 and a second extrusion block 62. The second positioning block 61 is slidably installed on the connecting plate 3. The second positioning block 61 is provided with a positioning groove 611 for positioning the movable side end plate at one end close to the first positioning block 51; the second extrusion block 62 is movably arranged above the second positioning block 61 and can be moved toward the first positioning block 51 to push the movable side end plate to move so that the battery cell is clamped between the reference side end plate and the movable side end plate. The center line of the second extrusion block 62 is collinear with the center line of the first extrusion block 52.

[0047] The module stacking tool provided in this embodiment supports the battery cell through the battery cell support component 4, and its length is adjustable, compatible with modules of different lengths, and the reference side positioning component 5 and the movable side positioning component 6 are respectively located on both sides of the battery cell support component 4. The positioning column 511 set on the top of the first positioning block 51 is plugged into the reference side end plate, and the positioning groove 611 set at one end of the second positioning block 61 close to the first positioning block 51 is used to position the movable side end plate, and the second extrusion block 62 moves toward the first positioning block 51, pushing the movable side end plate to move so that the battery cell is clamped on the reference side. The module is extruded between the end plate and the movable side end plate; the lifting component 2 is connected to the connecting plate 3 to adjust the height of the connecting plate 3 to adapt to battery modules of different heights. The positions of the first extrusion block 52 and the second extrusion block 62 that contact the battery module are consistent with the center of gravity height of the battery cell, which meets the needs of modules of different heights; for different types of battery modules, it is only necessary to replace the first positioning block 51 and the second positioning block 61 of the corresponding form, and the most expensive and largest battery cell support component 4 does not need to be replaced, which greatly reduces costs and shortens the tooling replacement time when changing models, thereby improving efficiency.

[0048] In some embodiments, a slide rail 7 is provided on the connecting plate 3. The cell support assembly 4 includes a first support plate 41 and a second support plate 42 slidably mounted on the slide rail 7. The first positioning block 51 is mounted on the end of the first support plate 41 away from the second support plate 42. The second positioning block 61 is slidably mounted on the slide rail 7. The slide rail 7 is provided on the connecting plate 3. The cell support assembly 4 includes the first support plate 41 and the second support plate 42 slidably mounted on the slide rail 7. The first support plate 41 and the second support plate 42 slide on the slide rail 7 to achieve adjustable length of the cell support assembly 4. The first positioning block 51 is mounted on the end of the first support plate 41 away from the second support plate 42, so that the reference side end plate moves with the first support plate 41, achieving adjustable position of the reference side end plate. The second positioning block 61 is slidably mounted on the slide rail 7 to achieve adjustable position of the movable side end plate. The reference side end plate and the movable side end plate meet the requirements of adapting to battery modules of different lengths, thereby improving the reliability of the device.

[0049] In some embodiments, a plugging notch 411 is provided on a side of the first support plate 41 close to the second support plate 42, and a plugging block 421 is provided on the second support plate 42 to match the plugging notch 411. Since the plugging notch 411 is provided on the side of the first support plate 41 close to the second support plate 42, the first support plate 41 actually forms a strip-shaped structure similar to the plugging block 421, and the plugging block 421 is provided on the second support plate 42 to match the plugging notch 411, thereby forming a notch groove similar to the plugging notch 411. The plugging blocks 421 are plugged into the plugging notch 411, which is actually staggered insertion. This can shorten the length of the tooling while meeting the adjustment range, making the structure more compact and small, reducing costs, and facilitating flexible arrangement of the tooling.

[0050] In some embodiments, the first support plate 41 is provided with a first fixing hole 412, the second support plate 42 is provided with a second fixing hole 422, and the slide rail 7 is provided with a first connection hole 71 that matches the first fixing hole 412 and a second connection hole 72 that matches the second fixing hole 422. Multiple groups of first connection holes 71 and second connection holes 72 are provided on the slide rail 7 at regular intervals. When the first support plate 41 and the second support plate 42 slide to the desired positions, T-shaped nuts are passed through the first fixing holes 412 to connect with the first connection holes 71 at the corresponding positions, and T-shaped nuts are passed through the second fixing holes 422 to connect with the second connection holes 72 at the corresponding positions, thereby securing the first support plate 41 and the second support plate 42 to the slide rail 7. This prevents the first support plate 41 and the second support plate 42 from sliding when placing battery cells, thereby preventing the battery cells from being placed empty and lacking support, thereby improving the stability and reliability of the tooling.

[0051] In some embodiments, the reference-side positioning assembly 5 further includes a fixing base 53, which is mounted on the base plate 1 and connected to the first extrusion block 52. By mounting the fixing base 53 on the base plate 1 and connecting it to the first extrusion block 52, the height of the first extrusion block 52 can be adjusted as high as possible to cooperate with the lifting assembly 2 to adapt to battery modules of different heights, thus expanding its applicability.

[0052] In some embodiments, a hollow portion 531 is provided at the bottom of the fixing seat 53, and the hollow portion 531 is used to avoid the slide rail 7. By providing the hollow portion 531 at the bottom of the fixing seat 53 to avoid the slide rail 7, the length of the bottom can be better utilized, so that the slide rail 7 can partially pass through the hollow portion 531, making the structure more compact and improving the applicability of the tooling.

[0053] In some embodiments, the lifting assembly 2 includes a main pushing member 21 and two stabilizing members 22. The main pushing member 21 abuts the center of the bottom surface of the connecting plate 3, and the two stabilizing members 22 abut the bottom surface of the connecting plate 3 and are symmetrically arranged on both sides of the main pushing member 21. Because the lifting assembly 2 includes a main pushing member 21 and two stabilizing members 22, the main pushing member 21 abuts the center of the bottom surface of the connecting plate 3, and the two stabilizing members 22 abut the bottom surface of the connecting plate 3 and are symmetrically arranged on both sides of the main pushing member 21, while the main pushing member 21 pushes the connecting plate 3 to rise and fall, the two stabilizing members 22 rise and fall synchronously, making the connecting plate 3 more stable during the lifting process, thereby improving the stability and reliability of the device.

[0054] In some embodiments, the main push member 21 includes a first linear bearing 211, a screw rod 212, and a main push block 213. The first linear bearing 211 is mounted on the bottom surface of the base plate 1 and is driven and connected to the screw rod 212. The main push block 213 is connected to the screw rod 212 and abuts against the center of the bottom surface of the connecting plate 3. The screw rod 212 is driven by a metal bearing to move, thereby driving the main push block 213 to move up and down, thereby achieving the lifting and lowering of the connecting plate 3. The first linear bearing 211 is a linear motion system produced at low cost. Since the load-bearing ball is in point contact with the shaft, the load is small and the steel ball rotates with extremely small friction resistance, thereby achieving high-precision and smooth motion.

[0055] In some embodiments, the stabilizing member 22 may include two second linear bearings 221 and a connecting rod 222. The second linear bearing 221 is installed on the base plate 1. The bottom of the second linear bearing 221 is connected by a connecting rod 222. The top support is connected to the bottom surface of the connecting plate 3. The two sides of the main pushing member 21 are supported by two points respectively to form a linear support, thereby improving the stability and reliability of the support.

[0056] In some embodiments, the top of the second positioning block 61 is provided with an escape groove 612, the width of which is greater than the width of the second extrusion block 62. By providing the escape groove 612 on the top of the second positioning block 61 and the width of which is greater than the width of the second extrusion block 62, the escape groove 612 does not affect the movement of the second extrusion block 62 as it moves toward the first extrusion block 52, thereby enabling the connection plate 3 to be raised to a higher height and improving the reliability and stability of the device.

[0057] In some embodiments, the module stacking tool further includes a first frame 8 and a drive device 9. The first frame 8 is located on a side of the base plate 1. The drive device 9 is mounted on the first frame 8 and connected to the second extrusion block 62 to push the second extrusion block 62 toward the first extrusion block 52. The drive device 9 can be a servo electric cylinder. The output shaft of the drive device 9 is connected to the second extrusion block 62 to drive the second extrusion block 62 to move toward the first extrusion block 52.

[0058] In some embodiments, the module stacking tooling further includes a second frame 10, which is mounted below the base plate 1. Four universal wheels 101 are provided at the bottom of the second frame 10 to facilitate movement of the tooling. In actual design, the first frame 8 and the second frame 10 can be integrated into a single unit, reducing costs, eliminating alignment operations, and improving assembly efficiency.

[0059] The working principle of the module stacking tool is as follows: the reference side end plate is inserted into the positioning column 511, the movable side end plate is placed in the positioning groove 611, and the battery cell is placed on the battery cell support assembly 4. The second extrusion block 62 is driven by the driving device 9 to move toward the first positioning block 51, pushing the movable side end plate to move so that the battery cell is clamped between the reference side end plate and the movable side end plate, thereby realizing the extrusion molding of the module; the first support plate 41 and the second support plate 42 slide on the slide rail 7, thereby realizing the length adjustment of the battery cell support assembly 4; the lifting assembly 2 is connected to the connecting plate 3 to adjust the height of the connecting plate 3 to adapt to battery modules of different heights. The positions of the first extrusion block 52 and the second extrusion block 62 contacting the battery module are consistent with the center of gravity height of the battery cell to meet the needs of modules of different heights; for different types of battery modules, only the corresponding first positioning block 51 and the second positioning block 61 need to be replaced, and the most expensive and largest battery cell support assembly 4 does not need to be replaced, which greatly reduces costs and shortens the tool replacement time when changing models, thereby improving efficiency.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
