Description

Technical Field

[0001] This utility model belongs to the field of new energy battery cell technology, specifically relating to an integrated tooling for battery cell module overlay welding. Background Technology

[0002] With the widespread adoption of new energy equipment and portable electronic devices, the demand for efficient, stable, and high-density energy storage devices is becoming increasingly urgent, leading to continuous market growth. The core component of an energy storage device is the battery cell module, which is composed of multiple battery cells welded together by connecting pieces. The welding quality of the battery cell module directly determines the safety, stability, and service life of the energy storage device.

[0003] Existing technologies require at least two people to work together during production, manually operating the terminals, which can easily lead to cell fires and pose a safety hazard to the operators. Therefore, existing technologies typically provide single-sided support fixtures. However, with this support structure, the cells are prone to loosening during welding, affecting the yield rate of the welded cells. Utility Model Content

[0004] This utility model provides an integrated welding fixture for battery cell modules, which aims to solve the problem of existing single-sided support fixtures, where the battery cells are prone to loosening during the welding process, affecting the yield of battery cell welding.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A battery cell module welding integrated fixture is provided, comprising a base, a battery cell frame, a stacking compartment, a side clamping member, and an upper clamping member. The battery cell frame is connected to the base; the stacking compartment is located on one side of the battery cell frame; the side clamping member includes a side locking member connected to the battery cell frame, and a clamping plate is connected to the side locking member. In the locked position, the side locking member provides clamping force for the clamping plate to hold the battery cell assembly on the stacking compartment; the upper clamping member includes an upper locking member connected to the battery cell frame, and a connecting plate is connected to the upper locking member. In the locked position, the upper locking member provides clamping force for the connecting plate to hold the battery cell assembly on the stacking compartment.

[0006] Furthermore, the side locking component includes a sleeve, a guide rod, a connecting plate, a take-up and release fixing seat, a take-up and release rod, a sliding cylinder, a first rotating frame, and a rotating clamp. The sleeve is connected to the battery cell frame and is symmetrically arranged on both sides of the stacking compartment. The guide rod is slidably connected to the sleeves on both sides, and the clamp is connected to one end of the guide rod. The connecting plate is connected to the other end of the guide rod. The take-up and release fixing seat is connected to the battery cell frame. The take-up and release rod is connected to the take-up and release fixing seat. The sliding cylinder is connected to the middle of the connecting plate, and the sliding cylinder is slidably connected to the take-up and release rod. One end of the first rotating frame is rotatably connected to the sliding cylinder. The rotating clamp is L-shaped, with the outer end of the short side of the L-shaped rotating clamp rotatably connected to the take-up and release rod, and the inner end of the short side of the L-shaped rotating clamp rotatably connected to the end of the first rotating frame away from the sliding cylinder.

[0007] Preferably, the short side of the L-shaped rotating handle furthest from the center point is rotatably connected to the retracting rod, the short side of the L-shaped rotating handle closest to the center point is rotatably connected to the first rotating frame, and the end of the first rotating frame furthest from the rotating handle is rotatably connected to the sliding cylinder. Therefore, when the rotating handle is rotated for locking, the rotating handle moves the sliding cylinder away from the cell frame, and the sliding cylinder moves the connecting plate away from the cell frame. Subsequently, the guide rod drives the clamping plate to hold the battery pack on the stacking compartment, thereby fixing and clamping the cell pack in the lateral direction.

[0008] Furthermore, the locking component includes two hand-tightening screws, which are symmetrically arranged on both sides of the connecting plate support. Both hand-tightening screws are threadedly connected to the connecting plate support and rotatably connected to the battery cell frame.

[0009] Preferably, by manually tightening the screws, the connecting plate can more stably clamp the upper end of the battery cell, and the clamping force can be sensed to avoid damage to the battery cell.

[0010] Furthermore, the locking component includes a bearing housing, which is connected to the battery cell frame, and the hand-tightening screw is rotatably connected to the bearing housing.

[0011] Preferably, the hand-tightening screw is rotatably connected to the bearing housing by the bearing housing, thereby providing stable support for the hand-tightening screw.

[0012] Furthermore, urethane adhesive is attached to the clamp.

[0013] Preferably, urethane is a material with high strength and low compression deformation. It has both the rigidity of plastic and the elasticity of rubber, and is characterized by pressure resistance, shock absorption, impact resistance, oil resistance, acid and alkali resistance, wear resistance, and high temperature resistance. Therefore, it can safely and securely clamp the battery cell and has a long service life.

[0014] Furthermore, the stacking compartment includes several arc-shaped slots formed on the cell rack.

[0015] Preferably, the arc-shaped groove fits into the battery cell, thereby providing independent support for the battery cell and avoiding the problem of disordered battery cell arrangement.

[0016] Furthermore, the stacking compartment also includes several straight slots formed on the cell rack, the straight slots being located on both sides of the arc-shaped slot, and the straight slots being connected to a separating epoxy board.

[0017] Preferably, straight slots are provided on the cell frame, distributed on both sides of the arc-shaped slots. That is, the intersecting arc-shaped slots in the middle share a single straight slot, while the outermost edges of the arc-shaped slots at both ends each have a separate straight slot. Simultaneously, a separator epoxy board is snapped into each straight slot. Because epoxy resin boards possess excellent mechanical properties, high dielectric properties, resistance to surface leakage, excellent insulation properties such as arc resistance, and excellent alkali and acid resistance, their placement between the cells provides better separation and prevents leakage from a single cell from affecting adjacent cells.

[0018] Furthermore, the base has a cell groove, which is used to limit the bottom of the cell.

[0019] Preferably, the bottom of the battery cell in this application is circular, so a circular groove corresponding to the bottom of the battery cell is provided on the base, which can better fix the battery cell.

[0020] Furthermore, a rectangular flat-bottomed groove is provided on the connecting plate, which is located directly above the cell groove and is used to support the shoulder of the cell electrode post.

[0021] Preferably, the battery cell of this application is connected to a battery cell terminal. To provide more stable support for the battery cell from the connecting plate, a rectangular flat-bottomed groove is provided on the connecting plate. The width of the rectangular flat-bottomed groove is greater than the width of the battery cell terminal, and the length of the rectangular flat-bottomed groove is greater than the length of all the battery cell terminals arranged on the plane. That is, all the battery cell terminals can be located within the rectangular flat-bottomed groove.

[0022] Furthermore, the base is provided with several waist-shaped countersunk holes.

[0023] Preferably, a countersunk hole in the base is provided, so that the base can be fixed to the workbench or welding station in the welding room by bolts.

[0024] The advantages of this utility model compared with the prior art are as follows: The side clamping component, through the side locking component, drives the clamping plate to provide lateral clamping force to the battery cell assembly on the stacking compartment; the upper clamping component, through the upper locking component, drives the connecting plate support plate to provide upper clamping force to the battery cell assembly on the stacking compartment, so that the battery cell assembly is stably fixed on the stacking compartment and the base, avoiding the displacement of the battery cell due to vibration during the welding process, ensuring the accuracy of the welding path, and reducing the need for repeated adjustments; the clamping plate and the connecting plate support plate provide uniform and continuous clamping force through the mechanical locking structure, effectively suppressing the deformation of the battery cell assembly caused by local thermal expansion during the welding process, reducing defects such as incomplete welding and cracks, and improving the weld strength and conductivity; by replacing manual support operation with a rigid structure, the influence of operator skill differences on welding quality is eliminated, and the yield rate is improved; at the same time, the risk of burns caused by manual support of battery cells is reduced.

[0030] In addition, the stacking compartment 3 is directly machined on one side of the cell frame 2 to accommodate and position the cells. The base 1, cell frame 2, clamping plate 42 and connecting plate support 52 are all made of insulating materials, such as polybutylene terephthalate, polycarbonate or glass fiber reinforced engineering plastic sheet.

The base 1 has a seat hole, and the battery cell frame 2 has a screw hole. A screw passes through the seat hole and is threaded into the screw hole. Thus, the battery cell frame 2 is connected to the base 1 via the screw. Alternatively, using snap-fit ​​or welding to connect the battery cell frame 2 to the base 1 also falls within the scope of this application.

[0032] See Figure 2 and Figure 3As shown, in some embodiments, the side lock 41 includes a sleeve 411, a guide rod 412, a connecting plate 413, a retractable fixing seat 414, a retractable rod 415, a sliding cylinder 416, a first rotating frame 417, and a rotating clamp 418.

[0033] In this embodiment, the sleeve 411 is welded to the cell frame 2 to provide sliding support for the guide rod 412. During welding, it is ensured that the axis of the sleeve 411 is parallel to the cell arrangement direction of the stacking compartment 3, with an axial deviation of less than or equal to 0.05 mm. An example of the sleeve 411's specifications is an inner diameter of 12 mm and a length of 50 mm. The corresponding guide rod 412 has a diameter of 11.95 mm to ensure precise movement. The number of sleeves 411 and guide rods 412 can be adjusted according to actual needs. For example, two sleeves 411 may be provided on one side of the cell frame 2, and two sleeves 411 may be provided on the other side of the cell frame 2 to ensure more precise movement of the guide rod 412.

[0034] In addition, the clamping plate 42 is arranged horizontally and is located in the middle of the stacking compartment 3. As a result, tape can be wrapped around the battery cells on the stacking compartment 3 on the upper and lower sides of the clamping plate 42 to secure the battery cell assembly.

[0035] Meanwhile, the take-up and release fixing seat 414 is connected to the cell frame 2, the take-up and release rod 415 is connected to the take-up and release fixing seat 414, the connecting plate 413 is connected between the guide rods 412 on both sides, the sliding cylinder 416 is fixed in the middle of the connecting plate 413, and the take-up and release rod 415 is slidably connected to the sliding cylinder 416. When the diameter of the take-up and release rod 415 is 10mm, the inner diameter of the sliding cylinder 416 is 10.1mm to ensure the stable movement of the sliding cylinder 416.

[0036] Finally, the length of the long side of the L-shaped rotating handle 418 is set to 80 to 100 mm, and the length of the short side is set to 30 mm. The outer side of the short side of the L-shaped rotating handle 418 is rotatably connected to the retracting rod 415 via a pin, and the inner side of the short side of the L-shaped rotating handle 418 is rotatably connected to the first rotating frame 417 via a pin. Therefore, when the locking and unlocking positions need to be changed, the operator only needs to hold the long side of the L-shaped rotating handle 418 and rotate it to move the position of the clamping plate 42.

[0037] See Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the locking member 51 includes a hand-tightening screw 511. There are two hand-tightening screws 511, which are symmetrically arranged on both sides of the connecting plate 52. Both hand-tightening screws 511 are threadedly connected to the connecting plate 52, and both hand-tightening screws 511 are rotatably connected to the battery cell frame 2.

[0038] In this embodiment, two hand-tightening screws 511 are threadedly connected to the connecting plate support 52. Thus, by rotating the hand-tightening screws 511, the position of the connecting plate support 52 can be adjusted.

[0039] See Figure 5 and Figure 6 As shown, in some embodiments, the locking member 51 includes a bearing seat 512, which is connected to the battery cell frame 2, and the hand-tightening screw 511 is rotatably connected to the bearing seat 512.

[0040] In this embodiment, the bearing housing 512 can be selected as 608ZZ, and the hand-tightening screws 511 are symmetrically arranged on both sides of the cell frame 2. At the same time, it is also necessary to ensure that the axis of the bearing housing 512 is horizontal and corresponds to the stacking compartment 3. The bottom of the hand-tightening screw is connected to the bearing housing 512, so that the hand-tightening screw 511 can rotate on the cell frame 2.

[0041] In addition, the handle of the hand-tightening screw is knurled to increase friction.

[0042] See Figure 3 As shown, in some embodiments, urethane adhesive 6 is attached to the clamp 42.

[0043] In this embodiment, the urethane adhesive 6 is used to buffer the battery cell when clamping it, thereby avoiding damage to the battery cell.

[0044] See Figure 1 As shown, in some embodiments, the stacking compartment 3 includes a plurality of arc-shaped slots 31 formed on the cell frame 2.

[0045] In this embodiment, according to the specifications of the battery cell, such as a cell diameter of 18mm, the radius of the arc surface of the arc groove 31 is 9mm, and the depth of the arc groove 31 is 10mm. At the same time, the arrangement of the arc groove 31 corresponds to the arrangement of the circular groove 11 of the battery cell to ensure stable support for the battery cell.

[0046] See Figure 1 and Figure 7 As shown, in some embodiments, the stacking compartment 3 further includes a plurality of straight grooves 32 formed on the cell frame 2, the straight grooves 32 being disposed on both sides of the arc-shaped groove 31, and the straight grooves 32 being connected to a separating epoxy plate 7.

[0047] In this embodiment, based on actual usage, the groove width of the straight groove 32 is designed to be 4mm and the groove depth to be 20mm, and a 3.8mm thick separating epoxy board 7 is inserted into the straight groove 32. The height of the separating epoxy board 7 is flush with or slightly less than the cell frame 2 to achieve separation and protection of the cell.

[0048] See Figure 1 As shown, in some embodiments, the base 1 has a cell groove 11, which is used to limit the bottom of the cell.

[0049] In this embodiment, the battery cell groove 11 is machined on the upper surface of the base 1 according to the arrangement and specifications of the battery cells. At the same time, the diameter of the battery cell groove 11 is 0.1-0.2mm larger than the bottom diameter of the battery cell to ensure the placement of the battery cell and to ensure precise positioning of the battery cell.

[0050] See Figure 2 As shown, in some embodiments, a rectangular flat-bottomed groove 521 is provided on the connecting plate 52. The rectangular flat-bottomed groove 521 is located directly above the cell circular groove 11 and is used to support the shoulder of the cell electrode post.

[0051] In this embodiment, the rectangular flat-bottomed groove 521 is located directly above the cell circular groove 11, and is used to support the shoulder of the cell electrode to prevent the electrode from deforming under stress during welding. In addition, a welding groove 5211 is provided on the connecting plate 52, and the welding copper nozzle 8 is installed on the welding machine. When welding is required, it moves to abut against the connecting plate 52 to weld the cell electrode.

[0052] See Figure 1 and Figure 2 As shown, in some embodiments, the base 1 has a plurality of waist-shaped countersunk holes 12.

[0053] In this embodiment, by providing a countersunk hole 12, it is possible to make adjustments within a certain range during fixing, which facilitates the adjustment of the installation position and allows for better use of bolts to fix the base 1 to the workbench or welding operation area.

[0054] In specific implementation of this utility model: See Figure 7 As shown, the base 1 is fixed to the workbench by using bolts and countersunk holes 12; Individual cells are placed into the stacking compartment 3 in sequence, while ensuring that the bottom of each cell is aligned with the cell groove 11 of the base 1 and the side of the cell is in contact with the arc surface of the arc groove 31. Insert the separator epoxy board 7 into the straight groove 32 to evenly separate adjacent cells and make the cells neatly arranged. Press and rotate the clamp handle 418. Rotating the clamp handle 418 pushes the sliding cylinder 416 to move away from the stacking compartment 3 along the take-up and release rod 415. The connecting plate 413 drives the guide rod 412 and the clamp plate 42 to approach the battery cell in the stacking compartment 3 until the urethane adhesive 6 on the clamp plate 42 is in close contact with the side of the battery cell. At this time, it is in the locked position. Using the upper and lower sides of the clamping plate 42 as a reference, wrap tape around the battery cell assembly to secure the module; Turn the two hand screws 511 to move the connecting plate 52 downward until the rectangular flat groove 521 at the bottom of the connecting plate 52 fits against the shoulder of the battery cell terminal, until you can clearly feel the resistance on the hand screws 511. At this time, the upper locking piece 51 is in the locked position. Place the connecting piece above the welding groove 5211 of the connecting piece tray 52, so that the welding point of the connecting piece corresponds one-to-one with the battery cell terminal, and fix it to the non-welding surface with masking tape. Remove the base 1 from the workbench and fix it to the welding station using the bolts and the countersunk hole 12. Start the welding equipment and weld the connecting piece to the cell electrode using the welding copper nozzle 8. The welding is completed and the cell assembly is formed by stacking. Turn the hand screw 511 to move the connecting plate 52 upward to detach it from the battery cell. At this time, it is in the unlocked position. Turn the rotating handle 418 to push the sliding cylinder 416 along the take-up and release rod 415 towards the stacking compartment 3. The connecting plate 413 drives the guide rod 412 and the clamping plate 42 away from the battery cell in the stacking compartment 3 until the urethane adhesive 6 on the clamping plate 42 is away from the side of the battery cell. At this time, it is in the unlocked position. Remove the battery cell assembly (see Figure 8 As shown in the figure, complete the entire operation process.
