[0010] Further, the top pressing mechanism comprises at least one pressing part slidingly arranged on the base plate, and when the number of the pressing parts is two or more, the distance between the adjacent two pressing parts is equal to the distance from the pressing part to the end of the battery module.

[0011] Furthermore, the substrate is provided with a first slide rail, and two first slide rails are symmetrically arranged on opposite sides of the substrate. The pressing part is disposed between the two first slide rails. The pressing part includes an adjustment seat slidably disposed on the first slide rail, a support seat disposed on the adjustment seat, and a pressing block detachably disposed on the support seat. The pressing block presses against the top of the battery module.

[0012] Furthermore, the top clamping mechanism also includes a first locking member, which is disposed on the adjusting seat and can be connected to the support seat to constrain the support seat to the adjusting seat.

[0013] Furthermore, the first locking member includes a handle disposed on the adjusting seat, a rotatable hanging ring disposed on the handle, and a hook disposed on the support seat; one end of the handle is hinged to the adjusting seat, and when an external force drives the handle to rotate toward the adjusting seat, the hanging ring can be hooked onto the hook, and when an external force drives the handle to rotate toward the support seat, the hanging ring can be disengaged from the hook.

[0014] Furthermore, the pressure block is also provided with a handle, which is plate-shaped, has a handle hole, and has multiple cutouts.

[0015] Furthermore, the top pressing mechanism also includes a support portion disposed on the substrate, wherein the support portion at the bottom of the battery module is opposite to the pressing portion at the top of the battery module.

[0016] Furthermore, the substrate is provided with a second slide rail, and the end pressing mechanism includes a fixing part fixed on the substrate, a sliding part slidably disposed on the second slide rail, and a first limiting plate and a second limiting plate respectively disposed on the fixing part and the sliding part; the first limiting plate and the second limiting plate are each provided with a limiting groove corresponding to the position of the terminal post of the battery module, and when the first limiting plate and the second limiting plate press against the battery module, each terminal post is located in the limiting groove.

[0018] Furthermore, the sliding part includes a sliding plate slidably disposed on the second slide rail, and the second limiting plate is disposed on the sliding plate.

[0019] Compared with the prior art, this utility model has the following advantages:

[0020] The module stacking fixture of this utility model places the battery modules on the stacking station, limits the two ends of the cell length direction by end clamping mechanisms, and presses the top clamping mechanism on the top surface of the battery module, thereby completing the stacking of the battery modules without loosening or tilting. At the same time, when the cell lengths of different batches of battery modules are different, the relative position of the top clamping mechanism and the battery module is adjusted along the length direction of the cell. This ensures that when the end clamping mechanisms at both ends of the cell are removed and the busbar is welded, the top clamping mechanism can still press the battery module to keep it in a stacked state, thus improving the applicability of the module stacking fixture.

[0021] Furthermore, when stacking battery modules using the top clamping mechanism, the clamping parts press against the battery modules along the stacking direction of the cells. When there are two or more clamping parts, they press against the battery modules at equally spaced positions, which helps to balance the pressure on the battery modules and ensures the flatness of the battery module stack. By setting the first slide rail, the adjusting seat slides more smoothly along the length direction of the cells, and the first slide rail also prevents the pressure blocks from shifting along the arrangement direction of the cells. Therefore, when the end clamping mechanism is removed, the battery modules remain stacked without tilting, improving the stability of battery module transfer. Moreover, when the cell heights of different batches of battery modules are different, by replacing the pressure blocks of different thicknesses that are detachable and mounted on the support base, the clamping parts are always pressed against the battery modules, thereby improving the usability of the module stacking tooling.

[0022] Furthermore, when the battery cells are stacked sequentially along their width, the adjusting seat and the support seat are separated by unlocking the first locking member. This allows the pressure block to be removed, facilitating the placement of the battery cells between the end clamping mechanisms and simplifying battery cell assembly. By configuring the first locking member to include a handle, a hanging ring, and a hook, the support seat can be easily attached to and detached from the adjusting seat.

[0023] Meanwhile, by providing a handle on the pressure block, it is easy to move the pressure block during assembly and disassembly. Multiple cutouts on the handle reduce its weight, thereby reducing excessive pressure on the battery module and achieving a lightweight design for the module stacking fixture. The addition of a support section allows the bottom surface of the battery module to detach from the substrate, providing a wider operating space between the battery module and the substrate when welding busbars onto the battery module, facilitating busbar welding.

[0024] Furthermore, by providing a fixing part fixed to the substrate and a sliding part slidably disposed on the second slide rail, when the cell lengths of different batches of battery modules are different, adjusting the sliding part along the length direction of the cell will clamp the battery module between the first limiting plate and the second limiting plate, thereby improving the applicability of the module stacking fixture. By providing positioning posts and positioning holes on the fixing part, positioning and assembly of the first positioning seat and the positioning plate can be facilitated.

Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.

[0045] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0046] This embodiment relates to a module stacking fixture for stacking different types of battery cells, thereby improving the applicability of the module stacking fixture.

[0047] In terms of overall structure, refer to Figure 1The module stacking fixture in this embodiment is used to stack battery cells 901 when welding busbars to battery module 9. The stacking fixture includes: a substrate 1, a top pressing mechanism 2 and an end pressing mechanism 3. The substrate 1 has a stacking station 1a, and the battery module 9 is located on the stacking station 1a when stacking. The top pressing mechanism 2 is slidably disposed on the substrate 1, and the pressing position of the top pressing mechanism 2 on the top of the battery module 9 is adjustable under the drive of external force. The end pressing mechanism 3 is disposed on the substrate 1 and can press against the end of the battery module 9 to limit the movement of the battery module 9 in the width direction.

[0048] As set up above, by placing the battery module 9 on the stacking station 1a, the end clamping mechanism 3 limits the two ends of the cell 901 along its length, and the top clamping mechanism 2 presses against the top surface of the battery module 9, thus completing the stacking of the battery module 9 without loosening or tilting. At the same time, when the length of the cell 901 of different batches of battery modules 9 is different, the relative position of the top clamping mechanism 2 and the battery module 9 is adjusted along the length of the cell 901. This ensures that when the end clamping mechanisms 3 at both ends of the cell 901 are removed and the busbar is welded, the top clamping mechanism 2 can still press the battery module 9 to keep it in a stacked state, thereby improving the applicability of the module stacking tooling.

[0049] Based on the above overview, refer to Figure 1 Specifically, the battery module 9 is formed by stacking multiple battery cells 901 along its width direction. The end clamping mechanism 3 is located at both ends of the battery cell 901 along its length direction, so that the end faces of the multiple battery cells 901 are coplanar, which facilitates the welding of busbars on the terminal post 9011. The top clamping mechanism 2 limits the height of the battery cell 901.

[0050] In practical applications, the battery module 9 formed by stacking battery cells 901 may encounter situations where there are crossbeams on the carrier for mounting the battery module 9. Therefore, it is understandable that a simulated crossbeam 101 can be set on the substrate 1. The length direction of the simulated crossbeam 101 is the same as the length direction of the battery cell 901, and it is set on the substrate 1 in a form that does not exceed the length and height of the battery cell 901. This ensures that after the battery module 9 with the welded busbar is removed from the module stacking fixture, there are reserved assembly spaces on the battery module 9.

[0051] As an feasible approach, refer to Figures 1 to 3The top pressing mechanism 2 includes at least one pressing part 201 slidably disposed on the substrate 1. Since the position of the top pressing mechanism 2 can be adjusted under external force, when there are two or more pressing parts 201, the distance between two adjacent pressing parts 201 can be adjusted to be equal to the distance from the pressing part 201 to the end of the battery module 9. When the battery module 9 is stacked using the top pressing mechanism 2, the pressing parts 201 are pressed onto the battery module 9 along the stacking direction of the cells 901. When there are two or more pressing parts 201, the multiple pressing parts 201 are pressed onto the battery module 9 at equally spaced positions, which helps to balance the pressure on the battery module 9 and helps to ensure the flatness of the stacked battery modules 9.

[0052] Based on the top pressing mechanism 2 including the pressing part 201, in order to improve the stability of the pressing part 201 during movement, the substrate 1 is provided with a first slide rail 4. Two first slide rails 4 are symmetrically arranged on opposite sides of the substrate 1, and the pressing part 201 is disposed between the two first slide rails 4. Specifically, as an implementable method, the pressing part 201 includes an adjusting seat 2011 slidably disposed on the first slide rail 4, a support seat 2012 disposed on the adjusting seat 2011, and a pressing block 2013 detachably disposed on the support seat 2012. The pressing block 2013 presses against the top of the battery module 9.

[0053] By setting the first slide rail 4, the adjusting seat 2011 slides more smoothly along the length direction of the cell 901. The first slide rail 4 also prevents the pressure block 2013 from shifting along the arrangement direction of the cell 901. As a result, when the end clamping mechanism 3 is removed, the battery module 9 remains in a stacked state without tilting, thus improving the transfer stability of the battery module 9. Furthermore, when the cell 901 heights of different batches of battery modules 9 are different, by replacing the pressure block 2013 of different thicknesses and models that is detachable and mounted on the support seat 2012, the clamping part 201 always presses the battery module 9, thereby improving the applicability of the module stacking fixture.

[0054] It is understandable that the first slide rail 4 is symmetrically arranged on opposite sides of the substrate 1, that is, the first slide rail 4 is located at both ends of the battery module 9 along the stacking direction of the battery cell 901, and the length direction of the first slide rail 4 is the same as the length direction of the battery cell 901. Both ends of the pressure block 2013 are detachably connected to support seats 2012, which are connected to adjusting seats 2011, thereby pressing the battery module 9 under the pressure block 2013. The pressure block 2013 and the support seat 2012 are detachably connected. There are various detachable methods, such as screw connection or snap-fit ​​connection. The actual detachable connection method is sufficient to ensure that the pressure block 2013 and the support seat 2012 do not separate on their own during the stacking process of the battery module 9, but can be separated when disassembly is required.

[0055] As a preferred example, to avoid damage to the battery cell 901 caused by hard contact between the pressure block 2013 and the battery cell 901, a layer of foam buffer can be attached to the side of the pressure block 2013 that contacts the battery cell 901, provided that the pressure block 2013 can press the battery cell 901 firmly. Specifically, this foam buffer layer can be made of foam with a thickness of 3-5mm. This foam buffer layer also helps to compensate for the gap between the pressure block 2013 and the battery module 9, so that the top pressing mechanism 2 can press against the top of the battery module 9.

[0056] As an example structure, refer to Figures 1 to 3 To facilitate the connection between the adjusting seat 2011 and the support seat 2012, the top clamping mechanism 2 further includes a first locking member 202. The first locking member 202 is disposed on the adjusting seat 2011 and can be connected to the support seat 2012 to constrain the support seat 2012 to the adjusting seat 2011. Specifically, the first locking member 202 includes a handle 2021 disposed on the adjusting seat 2011, a rotatable hanging ring 2022 disposed on the handle 2021, and a hook 2023 disposed on the support seat 2012. One end of the handle 2021 is hinged to the adjusting seat 2011. When an external force drives the handle 2021 to rotate toward the adjusting seat 2011, the hanging ring 2022 can be hooked onto the hook 2023. When an external force drives the handle 2021 to rotate toward the support seat 2012, the hanging ring 2022 can disengage from the hook 2023.

[0057] Before stacking the battery cells 901 sequentially along their width, the adjusting seat 2011 and the support seat 2012 are separated by unlocking the first locking member 202. This allows the pressure block 2013 to be removed, facilitating the placement of the battery cells 901 between the end clamping mechanisms 3 and exposing the stacking station 1a, thus facilitating the assembly of the battery cells 901. By configuring the first locking member 202 to include a handle 2021, a hanging ring 2022, and a hook 2023, it facilitates the installation and removal of the support seat 2012 from the adjusting seat 2011.

[0058] When the support base 2012 and the adjusting base 2011 are fixed using the first locking member 202, the hanging ring 2022 is hooked onto the hook 2023, and the handle 2021, which is hinged to the adjusting base 2011, is rotated away from the support base 2012 until the support base 2012 is pressed against the adjusting base 2011 and the hook 2023 is in a vertical position. When it is necessary to unlock the first locking member 202 to separate the adjusting base 2011 and the support base 2012, the handle 2021 is rotated towards the side closer to the support base 2012.

[0059] Since the module stacking fixture will clamp and transfer battery module 9 together with it for the next step of busbar soldering, in order to facilitate the soldering of the busbar on battery module 9, refer to... Figures 1 to 3The top clamping mechanism 2 also includes a support portion 203 disposed on the substrate 1. The support portion 203 is positioned at the bottom of the battery module 9, and the clamping portion 201 is positioned at the top of the battery module 9, opposite to the supporting position of the support portion 203. By providing the support portion 203, the bottom surface of the battery module 9 is detached from the substrate 1, providing a wider operating space between the battery module 9 and the substrate 1 when welding the busbar on the battery module 9, which facilitates the welding of the busbar.

[0060] As an example structure, the support portion 203 can be configured as a rectangular plate structure, and the support portion 203 extends along the stacking direction of the battery cells 901 so that each battery cell 901 is located on the support portion 203. Multiple support portions 203 can be provided along the length direction of the battery cells 901 to make the battery cells 901 more stable when placed on the support portion 203. In this embodiment, two sets of support portions 203 are selected as an example. When the length of the battery cells 901 in different batches of battery modules 9 changes, the support portion 203 can be removed from the substrate 1 and repositioned and installed on the substrate 1 so that one support portion 203 corresponds to one pressure block 2013, thereby making the pressure on the battery cells 901 more uniform.

[0061] Furthermore, refer to Figures 1 to 3 When placing the battery cell 901 on the stacking station 1a, in order to facilitate the handling and placement of the pressure block 2013 and to avoid the pressure block 2013 obstructing the stacking station 1a, the pressure block 2013 is also provided with a handle 5. The handle 5 is plate-shaped and has a handle hole 501 and multiple cutouts 502. By providing the handle 5 on the pressure block 2013, it is easy to move the pressure block 2013 when it is being disassembled and assembled. The multiple cutouts 502 on the handle 5 reduce the weight of the handle 5 itself, thereby reducing the overload pressure on the battery module 9 and realizing the lightweight design of the module stacking fixture.

[0062] In order for the end clamping mechanism 3 to clamp at both ends of the battery cell 901 along its length, refer to Figures 1 to 4 The substrate 1 is provided with a second slide rail 6. The end pressing mechanism 3 includes a fixing part 301 fixed on the substrate 1, a sliding part 302 slidably disposed on the second slide rail 6, and a first limiting plate 303 and a second limiting plate 304 respectively disposed on the fixing part 301 and the sliding part 302. The first limiting plate 303 and the second limiting plate 304 are each provided with a limiting groove 7 corresponding to the position of the terminal post 9011 of the battery module 9. When the first limiting plate 303 and the second limiting plate 304 press against the battery module 9, each terminal post 9011 is located in the limiting groove 7.

[0063] The number of limiting slots 7 is designed according to the requirements of the battery module 9. When the number of cells 901 changes, the first limiting plate 303 and the second limiting plate 304 with the corresponding number of limiting slots 7 can be replaced. By setting the fixing part 301 fixed on the substrate 1 and the sliding part 302 slidably set on the second slide rail 6, when the length of the cells 901 of different batches of battery modules 9 is different, the sliding part 302 is adjusted along the length direction of the cells 901, so that the first limiting plate 303 and the second limiting plate 304 clamp the battery module 9, thereby improving the applicability of the module stacking fixture.

[0064] As an feasible approach, refer to Figures 1 to 5 Specifically, the fixing part 301 includes a first positioning seat 3011 disposed on the base plate 1, and a positioning plate 3012 detachably disposed between the two first positioning seats 3011. A first limiting plate 303 is disposed on the positioning plate 3012. The first positioning seat 3011 is provided with a positioning post 8, and the positioning plate 3012 is provided with a positioning hole 8a. When the positioning plate 3012 is assembled on the first positioning seat 3011, the positioning post 8 passes through the positioning hole 8a. The sliding part 302 includes a sliding plate 3021 slidably disposed on the second slide rail 6, and a second limiting plate 304 is disposed on the sliding plate 3021. By providing the positioning post 8 and the positioning hole 8a on the fixing part 301, it is convenient to position and assemble the first positioning seat 3011 and the positioning plate 3012.

[0065] Specifically, the first positioning seat 3011 is located on the extension line of the length direction of the first slide rail 4. After the first limiting plate 303 is fixed to the positioning plate 3012, the first limiting plate 303 faces the battery module 9, and the first limiting plate 303 is directly opposite the second limiting plate 304. The length direction of the sliding plate 3021 is the same as the stacking direction of the battery cell 901. The sliding plate 3021 is formed with a groove that matches the second slide rail 6. When the length of the battery cell 901 is different, the sliding plate 3021 is adjusted on the second slide rail 6 so that both ends of the battery cell 901 are inserted into the limiting groove 7.

[0066] The positioning plate 3012 is detachably connected to the first positioning seat 3011. With this configuration, when transferring and welding the busbar of the stacked battery module 9, the first positioning seat 3011 can be removed from the substrate 1, or the positioning plate 3012 can be removed from the first positioning seat 3011. In both cases, the terminal post 9011 of the cell 901 can be exposed to facilitate subsequent busbar welding.

[0067] There are multiple ways to detachably connect the first positioning seat 3011 and the positioning plate 3012. For example, a bolt can be used to pass through the top surface of the positioning plate 3012 and then be inserted into the first positioning seat 3011 and threadedly connected to it. Alternatively, a first locking member 202 can also be provided between the first positioning seat 3011 and the positioning plate 3012. If the first positioning seat 3011 and the positioning plate 3012 are connected by the first locking member 202, a hook 2023 can be installed on the side of the positioning plate 3012, and a handle 2021 can be installed on the first positioning seat 3011. The first locking member 202 is set to unlock when the handle 2021 is turned toward the side closer to the positioning plate 3012, and to lock when the handle 2021 is turned toward the side away from the positioning plate 3012.

[0068] In this embodiment, the module stacking fixture is used by unlocking the first locking member 202, thereby separating the support base 2012 from the adjusting base 2011. The pressure block 2013 is transferred via the handle 5, and the battery cell 901 is placed on the support part 203 on the stacking station 1a. If different models of battery modules 9 are different, the sliding plate 3021 is pushed along the second slide rail 6, and both ends of the battery cell 901 are respectively inserted into the limiting grooves 7 of the first limiting plate 303 and the second limiting plate 304 for limiting. After positioning, place the pressure block 2013 on the battery module 9 along the stacking direction of the battery cell 901, adjust the position of the adjusting seat 2011 so that it is located at the center of the length direction of the battery cell 901, and use the first locking member 202 to connect the adjusting seat 2011 and the support seat 2012 so that the pressure block 2013 presses the battery cell 901, completing the stacking of the battery module 9. After removing the fixing part 301 and the sliding part 302 from the substrate 1, transfer the battery module 9, the top pressing mechanism 2 and the substrate 1 together for busbar welding.

[0069] By placing the battery module 9 on the stacking station 1a, the end clamping mechanism 3 limits the two ends of the cell 901 along its length, and the top clamping mechanism 2 presses against the top surface of the battery module 9, thus completing the stacking of the battery module 9 without loosening or tilting. At the same time, when the length of the cell 901 of different batches of battery modules 9 is different, the relative position of the top clamping mechanism 2 and the battery module 9 is adjusted along the length of the cell 901. This ensures that when the end clamping mechanisms 3 at both ends of the cell 901 are removed and the busbar is welded, the top clamping mechanism 2 can still press the battery module 9 to keep it in a stacked state, thereby improving the applicability of the module stacking tooling.

[0070] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
