[0036] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0037] With the rapid development of new energy technologies, batteries are increasingly being used in applications such as automobiles and portable electronic devices. The sealing performance of batteries is directly related to product safety and reliability. In the battery manufacturing process, the tight positioning of the sealing pins is a critical step, ensuring that the battery's injection hole is effectively sealed, preventing electrolyte leakage and the intrusion of foreign matter.

[0038] However, existing battery sealing pin positioning devices often have limitations. They are unable to adjust specifically to batteries of varying models or sizes. This lack of flexibility prevents precise positioning of the sealing pins, potentially leading to poor sealing and compressive damage, impacting battery performance and lifespan.

[0039] In order to solve the problems in the prior art, the present application provides a positioning device which adopts an adjustable design, can achieve accurate compression and positioning of the sealing nail, and improve the versatility of the positioning device.

[0040] Reference Manual Figure 1 , the present application provides a positioning device, which is designed to improve the efficiency and accuracy of the battery 8 sealing process. The device includes a clamping element 3, an adjustment assembly, a first base 1 and a second base 2. The clamping element 3 is responsible for applying the necessary pressure to the sealing pin 7 to ensure its precise positioning. The adjustment assembly includes a horizontal adjustment mechanism and an angle adjustment mechanism. These two mechanisms work together to enable the clamping element 3 to move along the X-axis and / or Y-axis, and to swing or rotate around a preset point to accommodate batteries of different sizes and models.

[0041] The first base 1 houses the adjustment assembly, while the second base 2 supports the battery 8, ensuring stability during the compression process. Adjustment of the adjustment assembly allows for autonomous control of the relative distance and position between the compression element 3 and the sealing pin 7, achieving adaptability to different battery models.

[0042] Specifically, the horizontal adjustment mechanism enables the pressing element 3 to move along the X-axis and Y-axis. Movement in the X-axis allows the pressing element 3 to be positioned in the width direction (or length direction, depending on the placement of the battery 8) of the battery 8, while movement in the Y-axis allows the pressing element 3 to be positioned in the length direction (or width direction, depending on the placement of the battery 8) of the battery 8. This two-way adjustment capability ensures that the pressing element 3 can adapt to batteries of different sizes, regardless of how their length or width varies.

[0043] In this embodiment, by providing an angle adjustment mechanism, the compression element 3 forms an adjustable area, such as a fan or semicircular shape, when it rotates. As long as the sealing pin 7 is located within this preset area, the compression element 3 can effectively compress it. This design is particularly suitable for situations where there is a certain tolerance in the position of the sealing pin 7, or when the position of the sealing pin 7 of the battery 8 varies slightly due to manufacturing tolerances. The angle adjustment mechanism allows the compression element 3 to compress the sealing pin 7 at any position within this area, thereby ensuring the sealing quality of the battery 8.

[0044] In some implementations, the horizontal adjustment mechanism can adopt a combination of a lead screw and a guide rail, and the lead screw can be driven by an electric or pneumatic motor so that the clamping element 3 can move smoothly along the guide rail in the X-axis and Y-axis directions; the angle adjustment mechanism can be designed as a rotating platform, and the clamping element 3 is mounted on the platform. By controlling the motor, the platform can rotate around the vertical axis to achieve angle adjustment of the clamping element 3, forming an adjustable clamping area.

[0045] In addition, the device can quickly adapt to different battery models, reducing the time for production line adjustments and improving production efficiency. The horizontal and angle adjustment mechanisms provided therein ensure that the sealing pin 7 can be accurately pressed and positioned, thereby improving the sealing performance and reliability of the battery 8.

[0046] To further enhance the applicability and functionality of the present device, the positioning device can optionally be equipped with an automated control system, such as a PLC, to automatically adjust the pressing element 3, further improving operational simplicity and production efficiency. Furthermore, sensors, such as displacement sensors and pressure sensors, can be integrated to monitor the position and pressure of the pressing element 3 in real time, ensuring the accuracy and consistency of the pressing operation. Furthermore, a multi-station positioning device can be designed to process multiple batteries 8 simultaneously, further increasing the production capacity of the production line.

[0047] In one embodiment, the positioning device also includes an adjustment plate, and the adjustment component is at least partially connected to the adjustment plate. The adjustment plate is connected to the clamping element 3 to drive the clamping element 3 to move, providing a stable support platform for the clamping element 3, ensuring the stability and reliability of the clamping element 3 during positioning and clamping operations.

[0048] The adjustment assembly is connected to the adjustment plate through a series of mechanical structures. This connection can be direct or indirect via connecting rods, gears, or other transmission mechanisms. These connection methods ensure that adjustments to the adjustment assembly are accurately transmitted to the adjustment plate, thereby driving the corresponding movement of the pressing element 3.

[0049] It can be understood that based on the above content, the settings of the angle adjustment mechanism and the horizontal adjustment mechanism in this embodiment are more flexible. For example, the horizontal adjustment mechanism is set between the adjustment plate and the clamping element 3, which can not only indirectly connect the two, but also horizontally adjust the position of the clamping element 3. The angle adjustment mechanism is set on the adjustment plate and is set away from the horizontal adjustment mechanism, so that the clamping element 3 can be adjusted in angle when the horizontal position remains unchanged or the horizontal position changes. In this way, the two mechanisms do not conflict with each other and can work independently or together, thereby improving the adaptability and flexibility of the positioning device.

[0050] Furthermore, Figure 2 As shown, the adjustment plate includes a first adjustment block 61 and a second adjustment block 62, and the clamping element 3 is directly or indirectly connected to the second adjustment block 62. At the same time, the horizontal adjustment mechanism includes an X-axis adjustment mechanism 51. The X-axis adjustment mechanism 51 is used to adjust the movement of the second adjustment block 62 in the X-axis direction, thereby synchronizing the movement of the clamping element 3 in the X-axis direction, so that the clamping element 3 can perform precise horizontal movement in the length or width direction of the battery 8 to accommodate batteries 8 of different lengths or widths, so that the clamping element 3 can easily align with the sealing pin 7, ensuring the accuracy of the clamping operation. At the same time, the angle adjustment mechanism can drive the first adjustment block 61 to rotate, responsible for adjusting the angle of the clamping element 3 to adapt to the different positions of the sealing pin 7 and the specific shape of the battery 8, further enhancing the flexibility and adaptability of the positioning device.

[0051] It should be noted that the first adjustment block 61 and the second adjustment block 62 are detachably connected. The two adjustment blocks can be adjusted independently when necessary, or connected as a whole for overall adjustment according to specific application requirements. This connection method is usually achieved by bolts, pins or other quick-disassembly mechanisms, which is easy and quick to operate.

[0052] Specifically, when the two adjustment blocks are disconnected, each adjustment block can be adjusted independently, allowing the pressing element 3 to move horizontally in the X-axis direction accurately, while also allowing for angular adjustment to accommodate batteries 8 of varying sizes and shapes. When quick or rough adjustments are required, the first adjustment block 61 and the second adjustment block 62 can be connected together as a whole, depending on the specific situation, for adjustment to be performed as a whole.

[0053] In this embodiment, by integrating the horizontal and angular adjustment functions into two adjustment blocks, the overall positioning device structure is clearer and its functions more clearly defined. Furthermore, this design enhances adjustment flexibility, allowing the positioning device to accommodate batteries 8 of various sizes and shapes, from standard sizes to specialized shapes. Furthermore, by precisely controlling the position and angle of the pressing element 3, the present device improves the quality and reliability of the battery 8 seal and reduces the risk of seal failure due to inaccurate positioning.

[0054] In one embodiment, two arcuate grooves 610 arranged opposite to each other are provided on the first adjustment block 61, and the two arcuate grooves 610 form a pair of guide paths on the first adjustment block 61. A plurality of adapter holes 100 are configured on the top of the first base 1, and these adapter holes 100 are divided into two groups. Each group of adapter holes 100 matches an arcuate groove 610 on the first adjustment block 61. In each group of adapter holes 100, at least one adapter hole 100 is installed with a positioning pin 101, and the positioning pin 101 passes through the arcuate groove 610 on the first adjustment block 61.

[0055] As can be understood, the arrangement of this embodiment ensures that when the first adjustment block 61 needs to rotate, it can be ensured to rotate strictly along the contour of the arcuate slot 610. The positioning pin 101 serves to provide a physical constraint, preventing the first adjustment block 61 from moving or deviating in an undesired direction, thereby ensuring accurate adjustment. Furthermore, the simple mechanical structure of the positioning pin 101 and the arcuate slot 610 is easy to maintain and replace, reducing long-term maintenance costs.

[0056] In addition, when it is necessary to fix the position of the first adjustment block 61 to prevent it from accidentally rotating, this can be achieved by installing a fastener such as a bolt in the adapter hole 100, or by setting the positioning pin 101 in the form of a bolt. The bolt passes through the arc groove 610 of the first adjustment block 61 and the adapter hole 100 of the first base 1 to lock, firmly locking the first adjustment block 61 in place. This locking mechanism is simple and effective, ensuring that the first adjustment block 61 remains stable when no adjustment is required, thereby ensuring the accuracy and consistency of the position of the clamping element 3. The operator can easily adjust the position of the first adjustment block 61 as needed, and can quickly lock it again after the adjustment is completed to adapt to different working conditions.

[0057] Based on the above, optional, such as Figure 3 As shown, the angle adjustment mechanism includes a rotary cylinder 4, the output end of which is directly or indirectly fixed to the first adjustment block 61, while the fixed end is fixed to the first base 1. This design allows the rotary cylinder 4 to directly drive the first adjustment block 61 to rotate during operation. At the same time, because the first adjustment block 61 and the second adjustment block 62 can be connected and fixed, the angle of the pressing element 3 can be adjusted.

[0058] The rotary cylinder 4, acting as an actuator, converts compressed air energy into rotational motion. In this device, the rotary cylinder 4 receives commands from the control system and adjusts the compressed air input to open and close it, thereby controlling the rotation of the first adjustment block 61. Furthermore, the rotary cylinder 4 is relatively compact and occupies little space, making it suitable for integration into the positioning device, thus reducing the overall size of the device.

[0059] In one embodiment, Figure 2 As shown, the X-direction adjustment mechanism 51 includes a locking member, a first docking end 611 and a second docking end 621. The first docking end 611 is arranged on the first adjustment block 61, and the second docking end 621 is arranged on the second adjustment block 62. The first docking end 611 and the second docking end 621 are arranged corresponding to each other, and the first docking end 611 and the second docking end 621 are connected by a locking member.

[0060] Among them, when the locking piece is in a loosened state, the second adjustment block 62 can be displaced relative to the first adjustment block 61 to achieve position adjustment of the clamping element 3 in the X-axis direction. When the locking piece is in a locked state, the second adjustment block 62 is relatively fixed to the first adjustment block 61 to ensure that the position of the clamping element 3 is stable.

[0061] Specifically, the operator can easily adjust the position of the second adjustment block 62 relative to the first adjustment block 61 by controlling the loosening and locking states of the locking member. For example, the locking member can be loosened and locked by rotating, moving, or operating a control mechanism (such as a wrench, switch, or button).

[0062] Furthermore, as shown in the figure, the second adjustment block 62 is designed as a square plate structure, the second docking end 621 includes two runway grooves, and the two runway grooves are respectively arranged on the opposite side edges of the second adjustment block 62, and the first docking end 611 includes a plurality of adjustment holes, which are respectively arranged corresponding to the two runway grooves.

[0063] It can be understood that in this embodiment, the detachable connection between the first adjustment block 61 and the second adjustment block 62 is achieved through the provision of two runway grooves and adjustment holes. Several adjustment holes can provide multiple locking points. When one locking point is destroyed, another locking point can be used in time, or when the relative movable range of the second adjustment block 62 needs to be adjusted, a suitable adjustment hole can be selected for loading and unloading of the locking member.

[0064] In addition, as shown in the accompanying drawings, two runway grooves are symmetrically arranged on the second adjustment block 62. When the second adjustment block 62 is displaced in the X-axis direction, the runway grooves on both sides provide uniform support to prevent deflection and tilting.

[0065] Here, the locking member can be a combination of a bolt and a nut. The bolt passes through the adjustment hole and the runway groove, and the nut is sleeved on the end of the bolt. The operator controls the locking or loosening by twisting it. When loosened, the bolt is similar to the positioning pin 101 in the above embodiment, playing the role of physical limit, which can prevent the second limit block from falling off from the first limit block. At the same time, the second adjustment block 62 can move freely along the X-axis direction relative to the first adjustment block 61 to adjust the position of the clamping element 3. When it is necessary to fix the position of the second adjustment block 62, tightening the nut can lock the bolt, thereby fixing the second adjustment block 62. Of course, in some cases, the first docking end 611 and the second docking end 621 can both be hole-shaped structures. When adjustment is required, the bolt connection is released and the second limit block 62 is moved to achieve the X-axis displacement of the clamping element 3. After the adjustment is completed, the bolt is inserted into the hole to fix it.

[0066] In one embodiment, based on any of the above embodiments, the horizontal adjustment mechanism also includes a Y-axis adjustment mechanism, which is arranged at the bottom of the first base 1 to realize the displacement of the first base 1 in the Y-axis direction, thereby driving the clamping element 3 to synchronously displace in the Y-axis direction.

[0067] The Y-axis adjustment mechanism can be implemented in a variety of ways, such as by a screw drive, a rack-and-pinion mechanism, a sliding guide, or other forms of linear actuators. These mechanisms can provide smooth and precise Y-axis movement, ensuring that the first base 1 and the pressing element 3 can be accurately adjusted to the desired position.

[0068] like Figure 1 As shown, the horizontal adjustment mechanism includes a sliding groove 520 arranged at the bottom of the first base 1. At the same time, the horizontal adjustment mechanism also includes a support column and other similar structures (not shown in the figure) that match the sliding groove 520. This structure can be set on the ground or other bases. For example, the support column passes through the sliding groove 520 to form a sliding connection. When the first base 1 is to drive the upper clamping element 3 to move in the Y-axis direction, due to the setting of the sliding groove 520 and the support column, the first base 1 can slide.

[0069] In addition, a corresponding locking assembly can also be provided in the Y-axis adjustment mechanism, and when it is not working, the operator locks it to prevent the first base 1 from accidentally sliding.

[0070] In one embodiment, the first base 1 includes a bottom plate 11 , two side plates 12 and a top plate 13 , wherein the two side plates 12 are respectively connected to the bottom plate 11 and the top plate 13 to form a frame structure.

[0071] As shown in the figure, in order to further improve the load-bearing capacity and anti-deformation performance of the first base 1, a reinforcing rib plate 14 is added between the two side panels 12, which significantly improves the bending resistance of the side panels 12, thereby effectively improving the strength of the first base 1 and making the entire frame structure more solid.

[0072] On this basis, in order to reduce the weight of the first base 1 and improve the efficiency of material use, weight-reducing holes 120 are also provided on the two side panels 12. It should be noted that the weight-reducing holes 120 will not have a negative impact on the strength and durability of the first base 1 while reducing material usage and reducing weight.

[0073] This design effectively controls the weight of the first base 1 while maintaining sufficient strength and stability. This not only helps reduce the manufacturing cost of the entire positioning device, but also facilitates operators to quickly adjust and maintain it on the production line. Furthermore, the reduced weight also means greater convenience during transportation and installation, helping to improve the efficiency of the entire production line.

[0074] In one embodiment, a receiving groove is provided on the second base 2 so that the battery 8 can be placed in the correct position, which not only provides physical support for the battery 8 but also helps to keep the battery 8 stable during the pressing process.

[0075] Furthermore, the positioning device includes a battery pressure plate 9, which has a cutout portion to expose the sealing pin 7 of the battery 8. This allows the pressing element 3 to directly act on the sealing pin 7, while also ensuring that the battery 8 does not shift or misalign during the compression process. The battery pressure plate 9 and the second base 2 work together to form a clamping system that effectively restricts the movement of the battery 8 during the compression process.

[0076] During operation, the battery 8 is first placed in the receiving groove of the second base 2, and then the battery pressure plate 9 is lowered above the battery 8, and the sealing pin 7 of the battery 8 is positioned using its vacant part. The battery 8 is confined between the battery pressure plate 9 and the second base 2, ensuring that the battery 8 remains in the correct position when the clamping element 3 acts on the sealing pin 7, effectively preventing any displacement or misalignment of the battery 8 during the clamping process, and improving the positioning accuracy and the reliability of the battery 8 seal.

[0077] In addition, in some embodiments, the second base 2 of different sizes can be selected according to the height of the battery 8 to ensure that the relative position between the battery 8 and the clamping element 3 always remains correct; or, accommodating grooves of different depths can be set on the second base 2 to accommodate batteries 8 of different thicknesses to ensure that the clamping element 3 can be correctly aligned with the sealing pin 7; the height of the second base 2 can also be designed to be adjustable. By adjusting the height of the second base 2, it can be ensured that the relative position of the clamping element 3 and the sealing pin 7 is not affected by the height difference of the battery 8.

[0078] 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 noted 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 considered as the scope of protection of the present application.
