[0027] Combined with Figures 1 to 4As shown, according to a specific embodiment of the present application, a shaping device for a battery cell module is provided.

[0028] The battery cell module includes a plurality of battery cell monomers 1 arranged adjacent to each other in a first direction. The shaping device includes a shaping component 2. The shaping component 2 includes: a shaping member 3, which is arranged on one side of the battery cell module. The shaping member 3 extends along the first direction. The shaping member 3 is movably arranged relative to the battery cell module in a second direction. The shaping member 3 has a working position where it abuts against each battery cell monomer 1, and the shaping member 3 has a retracted position where it is disengaged from contact with each battery cell monomer 1; an installation position 4 is provided on the side of the top of the shaping member 3 facing the battery cell module; a limiting member 5 is arranged in the installation position 4. The limiting member 5 is detachably connected to the shaping member 3. A plurality of limiting portions 6 are provided on the side of the limiting member 5 facing the battery cell module. A limiting space is formed between adjacent limiting portions 6. The plurality of limiting spaces are arranged in one-to-one correspondence with the plurality of battery cell monomers 1. The limiting member 5 limits each battery cell monomer 1 in the first direction.

[0029] The first direction is the arrangement direction of each battery cell monomer 1, that is, Figure 1 the length direction of the battery cell module shown in

[0030] Applying the technical solution of the present utility model, the battery cell module is shaped by the shaping member 3, and at the same time, the limiting member 5 arranged on the shaping member 3 limits each battery cell monomer 1 in the first direction. The shaping member 3 and the limiting member 5 are detachable. On the one hand, simultaneous shaping and limiting are achieved. On the other hand, compared with a fixed-size shaping tooling, the limiting function for battery cells of various sizes can be realized by replacing the limiting part.

[0031] By arranging the shaping member to extend along the first direction and be movable along the second direction, it can ensure that the shaping member can accurately locate to the working position of each battery cell monomer, so as to effectively perform the shaping operation.

[0032] The installation position is provided at the top of the shaping member, and the limiting member can be detachably connected to the shaping member. This design makes the shaping device have a certain flexibility and can adapt to battery cell modules of different specifications or sizes.

[0033] By providing a plurality of limiting portions in the installation position and corresponding to the length direction of the battery cell module, the limiting member can accurately limit and control each battery cell monomer, ensuring the stability and accuracy during the shaping process.

[0034] The setting that the first direction and the second direction are perpendicular makes the shaping device more efficient in space utilization, and the shaping operation of the battery cell module can be realized in a limited space, improving the production efficiency.

[0035] The limiting member and the shaping member are detachably connected. This design makes the maintenance and adjustment of the shaping device more convenient and fast, enabling timely replacement or adjustment to maintain the stability and reliability of the shaping device.

[0036] Through precise positioning and stable limiting control, the efficiency and accuracy of the shaping process can be improved, thereby enhancing the production efficiency and quality of the battery cell module.

[0037] Figure 1 It is a schematic diagram of the usage example of the detachable and limitable shaping tooling.

[0038] Figure 2 It is the front view of the limiting block of the detachable and limitable shaping tooling. Among them, the limiting part and the shaping part are fastened by screws.

[0039] Figure 3 It is the isometric view of the shaping part of the detachable and limitable shaping tooling.

[0040] Figure 4 It is the top view of the detachable and limitable shaping tooling.

[0041] Furthermore, there are two shaping components 2, and the two shaping components 2 are respectively arranged on both sides of the battery cell module along the second direction.

[0042] By arranging the shaping components on both sides, it can ensure that both sides of the battery cell module can be evenly shaped. This can reduce the stress concentration of the shaping device on the battery cell module, improve the uniformity and stability of shaping. At the same time, performing the shaping operation can reduce the shaping time, thereby improving the shaping efficiency. The two shaping components working simultaneously can make the shaping process faster and shorten the production cycle.

[0043] By performing the shaping operation on both sides simultaneously, the production capacity of the shaping device can be increased. This can complete the shaping task faster, improve the production efficiency, and meet the requirements of mass production.

[0044] The two shaping components are respectively located on both sides of the battery cell module, which can provide more stable support and positioning, ensuring the stability and accuracy during the shaping process. This helps to reduce shaping errors caused by vibration or instability.

[0045] The shaping components respectively arranged on both sides can be independently controlled, with higher flexibility. According to production requirements, one or two shaping components can be selected to be enabled to achieve flexible production scheduling and production management.

[0046] Furthermore, the first direction is the length direction of the battery cell module, and the second direction is the width direction of the battery cell module.

[0047] Furthermore, a stepped structure is provided on one side of the top of the shaping part 3 facing the battery cell module, and the stepped structure forms an installation position 4.

[0048] The stepped structure can provide an accurate installation position to ensure that the limiting part 5 can be correctly installed on the shaping part 3. This can ensure the correct positional relationship between the limiting part and the shaping part, thus guaranteeing the accuracy and stability of the shaping process.

[0049] The stepped structure provides a stable installation platform for the limiting part, making the installation process simpler and faster. The staff can easily install the limiting part on the shaping part, reducing the complexity of the operation and possible errors.

[0050] The stepped structure can provide good support to ensure the stable installation of the limiting part. This can prevent the limiting part from moving or shaking during use, guaranteeing the stability and reliability of the shaping device.

[0051] Setting the stepped structure to form the installation position 4 makes the installation of the limiting part more convenient and fast, saving installation time. This can improve the working efficiency of the shaping device, shorten the time required for the shaping process, and improve production efficiency.

[0052] The stepped structure provides a fixed installation point, which can ensure that the relative positions of the limiting part and the shaping part remain consistent. This helps to ensure the accurate control of the position of the battery cell module by the limiting part during the shaping process, thereby improving the accuracy and stability of the shaping.

[0053] Furthermore, when the limiting part 5 is installed on the shaping part 3, the top plane of the limiting part 5 is flush with the cover plate of the battery cell 1.

[0054] By keeping the top plane of the limiting part flush with the cover plate of the battery cell, it can be ensured that the limiting position of the limiting part for the battery cell is accurate. This can ensure the correct position and attitude of the battery cell during the shaping process, improving the accuracy and consistency of the shaping.

[0055] Keeping the limiting part flush with the cover plate of the battery cell can reduce the possible errors introduced during the installation process. This can avoid shaping errors caused by improper installation or inaccurate installation of the limiting part, ensuring the stability and reliability of the shaping process.

[0056] Keeping the top plane of the limiting part flush with the cover plate of the battery cell can prevent the limiting part from causing unnecessary pressure or damage to the battery cell during the limiting process. This helps to protect the structural integrity and long-term reliability of the battery cell.

[0057] By ensuring that the limiting member is flush with the cover plate of the single battery cell, the adjustment and calibration time can be reduced, and the working efficiency of the shaping device is improved. This helps to shorten the time required for the shaping process and increase the production capacity of the production line.

[0058] Furthermore, the height of the top plane of the shaping member 3 is less than or equal to the shoulder height of the single battery cell 1.

[0059] Keeping the height of the top plane of the shaping member less than or equal to the shoulder height of the single battery cell can ensure that the shaping member does not interfere with other parts of the single battery cell. This can avoid unnecessary contact or collision with other parts of the single battery cell during the shaping process, thus protecting the structural integrity of the single battery cell.

[0060] Limiting the height of the shaping member can ensure that only specific parts of the single battery cell are contacted and processed during the shaping process. This can improve the accuracy and precision of shaping and ensure that the shaping result meets the requirements.

[0061] Furthermore, the limiting member 5 includes a limiting plate 7. The arrangement direction of the limiting plate 7 is the same as that of the shaping member 3. The limiting portions 6 are arranged on the limiting plate 7 at intervals along the first direction. One end of the limiting portion 6 is connected to the limiting plate 7, and the other end of the limiting portion 6 extends towards the side of the single battery cell 1.

[0062] By arranging the limiting portions 6 on the limiting plate 7 at intervals along the first direction and making them extend towards the side of the single battery cell 1, precise limiting control of the position of the single battery cell can be achieved. This can ensure that the position of the single battery cell is accurate during the shaping process, and improve the accuracy and stability of shaping.

[0063] The arrangement direction of the limiting plate 7 is the same as that of the shaping member 3, ensuring that the position of the limiting portion 6 relative to the shaping member 3 remains consistent. This can avoid shaping errors introduced by inconsistent positions of the limiting portions 6 and ensure the consistency and stability of the shaping process.

[0064] By connecting one end of the limiting portion 6 to the limiting plate 7, a firm support can be provided. This can ensure that the limiting portion 6 maintains a stable position during the limiting process, avoid limiting errors caused by vibration or instability, and improve the stability and reliability of the shaping device.

[0065] Furthermore, the limiting portion 6 is a convex structure extending towards the side of the single battery cell 1. The convex structure is arranged such that its width gradually decreases towards the single battery cell 1. One end of the convex structure extends into the gap formed by the two cover plates of two adjacent single battery cells 1.

[0066] The convex structure can form precise limiting contact with the cover plate of the battery cell 1. By extending the convex structure into the gap of the cover plate of the battery cell 1, the position of the limit can be ensured to be accurate, improving the precision and stability of the shaping process.

[0067] By contacting the cover plate of the battery cell 1, the convex structure can stably limit the position of the battery cell, avoiding the limit error caused by vibration or instability, and improving the stability and reliability of the shaping device.

[0068] The contact between the convex structure and the cover plate of the battery cell will not cause damage to other parts of the battery cell. This can avoid unnecessary damage to the battery cell during the limiting operation and extend the service life of the battery cell.

[0069] Through precise limiting and stable support, the efficiency of the shaping process can be improved. This can shorten the time required for the shaping process, improve production efficiency, and meet the requirements of the production line.

[0070] Furthermore, at least one of the shaping member 3 and the limiting plate 7 is provided with a bolt connection hole 8, and the shaping member 3 and the limiting plate 7 are detachably connected through the bolt connection hole 8.

[0071] Furthermore, the shaping device includes a driving part, the driving part is connected to the shaping member 3, and the driving part is used to drive the shaping member 3 to move relative to the battery cell module in the second direction, and the driving part is a cylinder.

[0072] As the driving part, the cylinder has high control precision and can achieve precise control of the movement of the shaping member 3. This can ensure that the movement of the shaping member 3 in the second direction meets the predetermined requirements and improve the accuracy and stability of the shaping process.

[0073] The cylinder has the characteristic of rapid response and can complete the movement of the shaping member 3 in a short time. This can improve the speed of the shaping process, shorten the shaping cycle, and improve production efficiency.

[0074] As a traditional driving device, the cylinder has the characteristics of stability and reliability. Compared with other driving devices, such as electric motors, the structure of the cylinder is relatively simple, the maintenance cost is low, the service life is long, and it can ensure the stability and reliability of the shaping device.

[0075] As the driving part, the cylinder can realize the automation of power transmission, avoid manual labor, reduce energy waste, and has the advantages of energy conservation and environmental protection.

[0076] In an alternative embodiment, the detachable and limitable shaping tooling fastens the limiting part and the shaping part with screws, adjusts the limiting part according to project requirements, and at the same time, the shaping part is flexibly combined with the restraint equipment / tooling through insert nuts.

[0077] Within the length range of the shaping part, it can be compatible with multiple specifications and models of module stacking, which is suitable for the production of different specifications of square battery cell modules using the same box type in the current mainstream. At the same time, the limit part can be quickly and flexibly replaced to improve production efficiency and reduce tooling costs.

[0078] The limit part is located at the position of the cell cover plate on the upper side of the cell. The upper side of the limit is flush with the cell cover plate, and the height is 10 - 15 mm. It is advisable to use materials with moderate insulation hardness such as POM. The height of the shaping part is less than or equal to the shoulder height of the cell (the total height of the cell except for the pole column). The shaping part uses materials such as POM / bakelite with good insulation and flatness, and at the same time has a certain rigidity. The limit part realizes the module limiting action synchronously when the module is stacked and shaped, and controls the consistency of the horizontal and cell spacing of the module with a set of tooling during the module stacking process. In addition, the structure of this application is simple and does not require complex machining to meet the shaping and limiting requirements. At the same time, it is not limited to the use of automated equipment and manual stacking carts, and has a wide range of applications and can be arbitrarily combined. The demand for single-module shaping is two, and they are used in pairs during use, and attention should be paid to the symmetry of the two toolings in the positive and negative directions.

[0079] In an optional embodiment, the shaping part and the limit part can be replaced with materials such as POM / bakelite with appropriate insulation strength and hardness.

[0080] Optionally, the cylindrical channels of the detachable shaping part and the detachable template, as well as the actual length dimensions of the spacing between the limiting points of the shaping part and the limit part and the design of the channel dimensions can be determined according to the type of battery to be assembled and the number of stacked cell modules for cooperation.

[0081] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects:

[0082] By setting the shaping tooling as a split type, separating the shaping part from the limit part, the device can replace the limit block according to the product size, and the shaping part can be universal, reducing the use cost.

[0083] Adopting a detachable template structure, this device can realize the limiting function of multiple sizes of battery cells by replacing the limit part relative to the shaping tooling with a fixed size. By disassembling and combining the limit tooling and the shaping tooling, rapid model change is achieved, reducing the tooling cost and the tooling model change time.
