[0049] In the current battery manufacturing industry, sealing nail equipment plays a vital role, especially in the fixing and assembly process of battery cells. These devices are responsible for fixing the battery cells in the appropriate position to facilitate subsequent sealing nail welding or other related operations. However, the sealing nail equipment in the prior art has some obvious shortcomings when handling different types of battery cells.

[0050] Specifically, traditional sealing nail equipment usually requires the use of jigs or fixtures of specific sizes to fix the battery cells. When the production line needs to change the battery cell model, these devices are often unable to adapt to the new battery cell size, requiring operators to remove the existing jigs and redesign and make new jigs according to the size of the new battery cell. This process not only increases production costs, but also prolongs the changeover time and affects production efficiency.

[0051] In addition, the process of remaking the fixture module is accompanied by a waste of human resources, as professionals are required to design, manufacture and install it. This reliance on specific fixtures limits the flexibility of the production line, reduces the speed of response to changes in market demand, and thus affects the market competitiveness of the product.

[0052] Based on the above problems, the present application provides a battery cell clamp that can quickly adapt to battery cells of different sizes, reduce changeover time and cost, and thus improve production efficiency.

[0053] Reference Manual Attached Figure 1 and Figure 2 The present application provides a battery cell clamp, which includes a base 1, a first clamping assembly, and a second clamping assembly. The base 1 serves as a supporting foundation for the entire clamp and provides the necessary stability.

[0054] The first clamping assembly and the second clamping assembly are responsible for clamping the long side and the short side of the battery core respectively. Both clamping assemblies are designed to be movably arranged on the base 1, ensuring that they can be adjusted accordingly according to the size of the battery core.

[0055] In particular, the first clamping assembly, the second clamping assembly and the base 1 together form a cell fixing position 10. The cell fixing position 10 is designed to be adjustable so that the clamp can adapt to cells of various sizes, thereby reducing downtime and costs caused by changing cell models on the production line.

[0056] In actual applications, the operator can quickly set the size of the battery cell fixing position by adjusting the positions of the first clamping assembly and the second clamping assembly according to the size of the battery cell to be fixed, thereby ensuring that the battery cell is stably fixed in the fixture in the working state, providing precise positioning and firm support for subsequent welding or assembly processes.

[0057] Furthermore, the first clamping assembly includes a long side pressing plate 31 and a first adjusting plate 32, wherein the long side pressing plate 31 is detachably connected to the first adjusting plate 32, so that the operator can adjust its position on the first adjusting plate 32, and the first adjusting plate 32 is movably arranged on the base 1, so that the long side pressing plate 31 can be adjusted in position according to the size of the battery cell, so as to achieve flexible clamping of the long side of the battery cell. This design significantly reduces the time and cost of remaking the clamp module due to the change of the battery cell model, and also reduces the waste of human resources.

[0058] The second clamping assembly can be movably arranged on the base 1, and cooperates with the long side pressing plate 31 in the working state to form the battery cell fixing position 10, so as to ensure that the battery cell can be effectively fixed in the short side direction. This long side and short side bidirectional clamping mechanism not only improves the positioning accuracy of the battery cell, but also enhances the stability of the production process.

[0059] In addition, it is understandable that the battery cell clamp includes a driving member, which, as the power source of the clamp, can be selected in the form of electric, pneumatic or hydraulic according to actual production needs, to drive the first clamping assembly and the second clamping assembly to move toward the battery cell fixing position 10, so as to achieve rapid clamping and fixing of the battery cell. This integrated design simplifies the operation process, reduces the need for manual adjustment, and also reduces the error rate during operation.

[0060] In one embodiment, based on the above embodiment, a calibration structure is provided in the first clamping assembly, and the calibration structure is provided on the first adjustment plate 32, so as to provide a precise reference point when adjusting the position of the long side pressure plate 31, thereby ensuring that the battery cell can be accurately fixed and adapted in various sizes, significantly improving the adjustment accuracy of the clamp and the convenience of operation.

[0061] It is understandable that the design of the calibration structure enables the operator to quickly identify and adjust the long side pressing plate 31 to the appropriate position to adapt to different sizes of battery cells. The setting of such reference points can be an intuitive scale, mark, or a more advanced digital display, which together simplify the adjustment process, reduce human errors, and speed up the changeover.

[0062] Specifically, when the battery cell model or size needs to be changed, the operator can quickly adjust the long side pressing plate 31 to the accurate position corresponding to the battery cell size by using the reference point on the calibration structure. This adjustment method not only saves time, but also reduces material waste and production delays caused by size mismatch.

[0063] In addition, the design of the calibration structure also makes the battery cell fixture more user-friendly and intelligent. The operator can quickly locate and fix the battery cell without relying on experience or complex measuring tools. This improves production efficiency while reducing the difficulty of operation, making the equipment easier to use and maintain.

[0064] Furthermore, if Figure 3 As shown, the calibration structure includes a scale 5, which provides an intuitive length reference. The scale 5 is arranged along the movement direction of the first adjustment plate 32, and is marked with a number of specific numerical points, each of which accurately corresponds to a reference point of a specific battery cell size, so that the operator can quickly adjust the long side pressing plate 31 to a corresponding position according to the specific size of the battery cell. The use of the scale 5 simplifies the adjustment process, making each adjustment faster and more accurate, and also reduces errors caused by human factors.

[0065] On the other hand, another calibration structure is also provided in the present application, and the calibration structure includes a positioning hole structure (not shown in the figure), which is composed of a series of equally spaced positioning holes, and each positioning hole corresponds to a reference point of a specific battery cell size. By adjusting the long side pressing plate 31 to align it with the corresponding positioning hole, the operator can synchronously adjust the size deviation between the battery cell fixing position 10 and the battery cell. This method not only improves the accuracy of the adjustment, but also makes the entire adjustment process more intuitive and easy to operate. Moreover, in this positioning hole structure, the density of the positioning holes can be adjusted to adjust its accuracy.

[0066] By setting the above two calibration structures, the battery cell clamp can adapt to battery cells of different sizes, and realize fast and accurate type change adjustment. Whether using the scale 5 for rapid positioning or using the positioning hole structure for fine adjustment, the operator can easily complete the battery cell fixing work according to production requirements, which greatly improves the practicality and application scope of the battery cell clamp and meets the requirements of modern production lines for high efficiency and high precision.

[0067] In another embodiment, the calibration structure further includes a fixing block 50, which is detachably disposed on the first adjustment plate 32, so that an operator can quickly replace or adjust the fixing block 50 to adapt to battery cells of different sizes or meet specific production requirements.

[0068] like Figure 3As shown, the fixing block 50 has a first end face 501 and a second end face 502 on opposite sides of the body, and the first end face 501 abuts against the surface of the long side pressing plate 31 away from the battery cell. After the calibration is completed, the first end face 501 is aligned with the reference point on the calibration structure, thereby ensuring that when the outside of the battery cell is clamped and fixed after the calibration, the battery cell fixing position 10 generated by the clamp can accurately match the size of the battery cell. The fixing block 50 not only provides a clear positioning reference, but also provides back support for the long side pressing plate 31, thereby improving the stability of the structure.

[0069] In addition, the second end surface 502 is connected to the driving member, so that the fixing block 50 can drive the first adjustment plate 32 to move relative to the base 1 under the driving action of the driving member. The driving member can use a push-pull cylinder to achieve bidirectional displacement. Similarly, other types of driving members can also be used to achieve the bidirectional push-pull function, which will not be described one by one here.

[0070] In one embodiment, different from the above embodiment, the second clamping assembly is provided with a linkage mechanism, and the second clamping assembly also includes a short side pressing plate 41 and a second adjusting plate 42 to achieve stable clamping of the battery cell.

[0071] The short side pressing plate 41 is fixed on the second adjusting plate 42, so that the short side pressing plate 41 can move in the direction of pressing the battery cell driven by the second adjusting plate 42. The second adjusting plate 42 is movably connected to the base 1, providing the necessary adjustment freedom, so that the short side pressing plate 41 can be adjusted in position according to the size and shape of the battery cell.

[0072] It should be noted that the linkage mechanism is connected to the second adjustment plate 42 and the first adjustment plate 32 at the same time, so as to achieve the synchronous displacement of the short side pressing plate 41 and the long side pressing plate 31. When the long side pressing plate 31 moves driven by the first adjustment plate 32, the linkage mechanism ensures that the short side pressing plate 41 can also move in a coordinated manner, so as to achieve uniform clamping of the battery cells in two vertical directions.

[0073] At the same time, this synchronous displacement can be achieved in various forms, such as connecting rods, gears, slide rails, etc., to adapt to different production needs and operating environments. The design of the linkage mechanism must ensure smooth operation to avoid uneven pressure on the battery cell, which may affect the performance of the battery cell or damage the battery cell.

[0074] Through the design of this linkage mechanism, the battery clamp not only improves the convenience of operation and the speed of battery cell fixing, but also ensures the accuracy and consistency of the clamping process. This design reduces the complexity of manual operation and improves the level of automation. It also makes it possible to quickly change the size of batteries, greatly improving production efficiency and the applicability of battery clamps.

[0075] Furthermore, the linkage mechanism includes a slide block 61 and a pulley 62, and the second clamping assembly includes a second slide rail 43. The slide block 61 is a key part of the linkage mechanism, and is provided with at least one inclined slide groove 610, and the pulley 62 is slidably embedded in the slide groove 610 and connected to the second adjustment plate 42.

[0076] The second slide rail 43 is arranged between the base 1 and the second adjustment plate 42, and its extension direction is toward the battery cell fixing position 10. The second adjustment plate 42 can move smoothly on the second slide rail 43, thereby driving the short side pressure plate 41 to move toward the battery cell fixing position 10, and the second slide rail 43 also plays a certain guiding role. The sliding of the pulley 62 in the sliding groove 610 can be understood as a change in the relative position of the pulley 62 and the sliding groove 610. In this process, due to the guiding effect of the second slide rail 43, the second adjustment plate 42 can only move to the upper or lower position in the accompanying drawing, which corresponds to the compression or release of the battery cell by the short side pressure plate 41.

[0077] During the overall clamping process: when the first adjustment plate 32 moves, the slide block 61 with the slide groove 610 also moves, driving the pulley 62 to slide synchronously in the groove, and the relative position between the pulley 62 and the slide groove 610 changes, and this change is converted into the movement of the second adjustment plate 42 along the second slide rail 43 through the inclined slide groove 610. Because the pulley 62 is connected to the second adjustment plate 42, the movement of the pulley 62 directly causes the second adjustment plate 42 to move along the second slide rail 43 toward the battery cell. As the second adjustment plate 42 moves, the short-side pressure plate 41 gradually approaches the short side of the battery cell and begins to apply a clamping force, thereby clamping the short side of the battery cell. The opposite is the release process, which will not be described here.

[0078] In one embodiment, the first clamping assembly includes a first slide rail 33, which is disposed between the base 1 and the first adjustment plate 32. The first slide rail 33 is mainly used to achieve relative sliding of the first adjustment plate 32. In other words, the first adjustment plate 32 moves precisely along the extension direction of the first slide rail 33 on the base 1, thereby adjusting the position of the long side pressing plate 31 to adapt to battery cells of different sizes. The design of the first slide rail 33 ensures the stability and smoothness of the first adjustment plate 32 during movement, and avoids jamming or uneven movement that may occur during the adjustment process.

[0079] At the same time, the extension directions of the first slide rail 33 and the second slide rail 43 are perpendicular to each other, so that the first adjustment plate 32 and the second adjustment plate 42 can move in their respective perpendicular directions, thereby realizing the synchronous adjustment of the long side pressure plate 31 and the short side pressure plate 41, thereby improving the space utilization and adjustment flexibility of the clamp.

[0080] In another embodiment, if Figure 1As shown, there are two long side pressing plates 31 and two first adjustment plates 32, and the two long side pressing plates 31 are symmetrically distributed on opposite sides of the base 1. The symmetrical configuration provides a balanced clamping force to ensure that the battery cell is evenly fixed in the long side direction while maintaining ease of operation. Correspondingly, each long side pressing plate 31 is paired with a first adjustment plate 32, so that the position of each long side pressing plate 31 can be adjusted independently.

[0081] The second clamping assembly includes fixed pressure plates 7, which are fixed on the base 1 to connect with one of the short sides of the battery cell. The fixed pressure plates 7 provide a stable support point for the battery cell, ensuring that the clamping in the short side direction is also accurate and stable.

[0082] The short side pressing plate 41 and the fixed pressing plate 7 are symmetrically distributed on the other two opposite sides of the base 1. In the process of fixing the battery cell, the short side pressing plate 41 will move toward the fixed pressing plate 7 and work together with the fixed pressing plate 7 to clamp the short side of the battery cell. This symmetrical clamping mechanism not only improves the operating efficiency of the clamp, but also ensures the position accuracy of the battery cell in the short side direction.

[0083] The cell fixing position 10 is formed by the fixed pressure plate 7, the long side pressure plate 31 and the short side pressure plate 41. This design ensures that the circumferential position of the cell can be stably fixed. The symmetrical layout and the pressure plates working in coordination provide a precise, uniform and stable clamping environment for the cell.

[0084] Furthermore, the number of the short-side pressing plates 41 and the number of the fixed pressing plates 7 are both two, and the number of the second adjustment plates 42 corresponds to the number of the short-side pressing plates 41 , and each short-side pressing plate 41 corresponds to a fixed pressing plate 7 .

[0085] The battery cell clamp also includes a central pressing plate 8, which is fixed to the base 1 and arranged between the two long side pressing plates 31. The function of the central pressing plate 8 is to separate the battery cell fixing position 10 into two independent fixed sub-positions 100, each of which is surrounded by the central pressing plate 8, a long side pressing plate 31, a fixed pressing plate 7 and a short side pressing plate 41. This design not only provides uniform clamping of the battery cell, but also allows independent clamping of the two battery cells as needed.

[0086] In the process of fixing the battery cell, each short side pressing plate 41 will work with its corresponding fixed pressing plate 7 to ensure that the short side of the battery cell is stably clamped. At the same time, in conjunction with the adjustable design of the long side pressing plate 31 in the above embodiment, the battery cell clamp can adapt to battery cells of different sizes and shapes, while providing an efficient fixing solution. The introduction of the central pressing plate 8 makes the application range of the battery cell clamp wider and can meet more diverse production needs.

[0087] In one embodiment, the design of the battery cell clamp takes into account the additional protection and stability of the battery cell during the fixing process, which is achieved by introducing rubber soft bags 9 on the above-mentioned pressure plate components (central pressure plate 8, fixed pressure plate 7, long side pressure plate 31, etc.). These rubber soft bags 9 are designed to provide a buffering effect to protect the battery cell from damage, and to enhance the friction between the clamp and the battery cell to ensure the stability of the battery cell in the fixed position.

[0088] Rubber soft bags 9 are respectively arranged on the two end surfaces of the central pressing plate 8 facing the fixed points 100. This design not only ensures the stability of the battery cell in the contact area of ​​the central pressing plate 8, but also provides additional protection to prevent the battery cell from any potential damage during the production process. The elastic properties of the rubber soft bag 9 help absorb possible impact and pressure, thereby protecting the integrity of the battery cell.

[0089] Similarly, each short side pressing plate 41 and long side pressing plate 31 is also provided with a rubber soft bag 9 on the end surface facing the battery cell fixing position 10. The design of these soft bags helps to provide soft support in the area where the clamp contacts the battery cell, reducing the damage that may be caused by hard contact. At the same time, the friction coefficient of the rubber material is high, which can improve the stability of the battery cell in the fixing position and prevent sliding or displacement during the production process.

[0090] It should also be noted that according to the specific needs of the clamp, for example, if a specific part of the battery cell is more fragile or requires more stable fixation, you can choose to add a rubber soft bag 9 to the corresponding pressure plate at that part. At the same time, the application of the rubber soft bag 9 is not limited to the adjustment of quantity or design position.

[0091] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications should also be regarded as the protection scope of the present application.
