Description

Technical Field

[0001] This utility model relates to the field of battery assembly tool technology, and more specifically, to a multi-module assembly and positioning device for a battery pack. Background Technology

[0002] With the booming development of the new energy industry, battery packs are being used more and more widely in electric vehicles, energy storage systems and other fields. A battery pack is usually assembled from multiple battery modules, and its assembly quality directly affects the performance, safety and service life of the battery pack.

[0003] In traditional battery pack multi-module assembly processes, positioning and assembly largely rely on manual operation or simple tooling fixtures. Manual operation, due to varying operator skill levels and habits, makes it difficult to guarantee the positioning accuracy of battery modules, easily leading to assembly deviations. This can affect the internal electrical connections and heat dissipation performance of the battery pack, and may even cause safety hazards. Using simple tooling fixtures, such as commonly available manual screw clamps or simple cylinder-driven clamps, results in fixed positions and dimensions, offering poor overall versatility and difficulty adapting to different specifications and models of battery modules. Furthermore, the time cost of changing tooling fixtures during batch assembly is high, severely restricting production efficiency. Therefore, we propose a multi-module assembly positioning device for battery packs. Utility Model Content

[0004] The purpose of this invention is to provide a multi-module assembly and positioning device for a battery pack, so as to solve the defects mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A multi-module assembly and positioning device for a battery pack includes an assembly panel. Two symmetrical support frames are fixedly mounted on the upper surface of the rear end plate of the assembly panel. A pressing assembly is provided on each of the two support frames. Each pressing assembly includes a first cylinder fixedly mounted on the top plate of the support frame. Guide plates are detachably connected to the ends of the telescopic shafts of the two first cylinders. Horizontally arranged pressing beams are fixedly mounted on the front sides of both ends of the guide plates. Multiple rectangular sleeves are slidably connected to the guide plates. Horizontally arranged positioning plates are fixedly mounted on the front sides of the rectangular sleeves. A U-shaped frame is fixedly mounted on the top surface of the guide plate. A limiting assembly for pressing and fixing the multiple rectangular sleeves is provided on the U-shaped frame. The limiting assembly includes a second cylinder fixedly mounted on the top plate of the U-shaped frame. A pressing limiting plate that presses against the rectangular sleeves is provided at the end of the telescopic shaft of the second cylinder.

[0007] Preferably, a plurality of vertically arranged support legs are fixedly installed on the bottom surface of the assembly panel, and a fixed base is fixedly installed at the bottom end of the support legs;

[0008] This setting enables stable support operation.

[0009] Preferably, a steel plate is fixedly installed at the end of the telescopic shaft of the first cylinder, and the guide plate and the steel plate are fixedly connected by multiple fastening bolts.

[0010] Preferably, the guide plate is provided with scale lines arranged along the length direction of the guide plate, and the rectangle is fitted onto the guide plate.

[0011] Preferably, a bolt plate is fixedly installed at the end of the telescopic shaft of the second cylinder, and the downward limiting plate is fixedly installed on the bottom surface of the bolt plate by a plurality of fastening bolts.

[0012] Preferably, the positioning plate is located between the two lower pressure beams, and a rubber pad is detachably connected to the bottom surface of the lower pressure beam;

[0013] The rubber pads mentioned above can prevent damage to the battery pack casing during the pressing process.

[0014] Preferably, a fixing plate is fixedly installed on the top surface of the rubber pad, and the fixing plate is fixedly installed on the bottom surface of the lower pressure beam by a plurality of fastening screws.

[0015] Preferably, a triangular positioning plate is fixedly installed on the top surface of the rectangular sleeve, and a plurality of linearly and equally spaced limiting grooves are provided on the bottom surface of the pressing limiting plate. The triangular positioning plate and the limiting grooves are engaged with each other, and the cross-sections of the triangular positioning plate and the limiting grooves are both triangular in shape.

[0016] This setting enables proper positioning and clamping of the rectangular sleeve, preventing it from shifting.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model, through the setting of the pressing component, the first cylinder drives the guide plate and the pressing beam to perform a pressing action, which can apply stable and uniform pressure to the outer shell of the battery module assembly, so as to achieve the effect of fixing and clamping, and thus prevent the battery module from moving up and down during the assembly process.

[0019] 2. This utility model, by setting scale lines on the guide plate and using a slidably connected rectangular sleeve and positioning plate, allows operators to intuitively adjust the position of the rectangular sleeve according to the specifications of the battery module using the scale lines. Combined with the second cylinder in the limiting assembly driving the downward pressing of the limiting plate and the triangular positioning plate, it achieves flexible positioning and secure fixing of battery modules of different specifications in the horizontal direction. This improves the versatility of the device, reduces the frequency of tooling and fixture replacement, lowers production costs, and increases production efficiency.

[0020] 3. This utility model features a rubber pad with a fixing plate detachably connected to the bottom surface of the pressure beam, and a limiting groove on the bottom surface of the pressure limiting plate that engages with the triangular positioning plate. When the battery module assembly shell is pressed down for positioning, the rubber pad effectively buffers the pressure, preventing damage to the battery pack shell. At the same time, the cooperation between the limiting groove and the triangular positioning plate ensures that the rectangular sleeve will not shift, thus achieving protection and precise positioning of the battery module. This improves the quality of battery pack assembly and enhances the error prevention and safety performance of the device. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-4 This utility model provides a technical solution: a multi-module assembly and positioning device for a battery pack, including an assembly panel 1. Two symmetrical support frames 12 are fixedly installed on the upper surface of the rear end plate of the assembly panel 1. A pressing component 2 is provided on the two support frames 12. The pressing component 2 includes a first cylinder 20 fixedly installed on the top plate of the support frame 12. The ends of the telescopic shafts of the two first cylinders 20 are detachably connected to guide plates 21. A horizontally arranged pressing beam 22 is fixedly installed on the front side of both ends of the guide plate 21. The pressing beam 22 can move downward to properly press the battery pack assembly shell on the assembly panel 1, avoiding displacement during assembly. In addition, a rubber pad 23 is detachably connected to the bottom surface of the pressing beam 22. A fixing plate 231 is fixedly installed on the top surface of the rubber pad 23. The fixing plate 231 is fixedly installed on the bottom surface of the pressing beam 22 by multiple fastening screws, avoiding direct contact between the pressing beam 22 and the battery pack shell to prevent pressure damage and protecting the appearance and internal structure of the battery pack.

[0031] like Figures 1-3 As shown, multiple rectangular sleeves 25 are slidably connected to the guide plate 21. A horizontally positioned positioning plate 24 is fixedly installed on the front side of the rectangular sleeve 25. The positioning plate 24 is located between two downward pressure beams 22 and is used to position the battery assembly in the horizontal direction. A U-shaped frame 26 is fixedly installed on the top surface of the guide plate 21. A limiting component 3 for pressing and fixing the multiple rectangular sleeves 25 is provided on the U-shaped frame 26. The limiting component 3 includes a second cylinder 30 fixedly installed on the top plate of the U-shaped frame 26. A downward pressure limiting plate 32 is provided at the end of the telescopic shaft of the second cylinder 30, which presses against the rectangular sleeve 25 to achieve the effect of pressing and fixing the rectangular sleeve 25 after the position is adjusted.

[0032] like Figure 1 As shown, multiple vertically arranged support legs 10 are fixedly installed on the bottom surface of the assembly panel 1. A fixed base 11 is fixedly installed at the bottom end of the support legs 10, so that the entire multi-module assembly and positioning device can obtain stable support, ensuring that the device will not shake or shift during the battery module assembly process, and providing a solid foundation for accurate positioning and assembly.

[0033] In this embodiment, a steel plate 201 is fixedly installed at the end of the telescopic shaft of the first cylinder 20, and the guide plate 21 is fixedly connected to the steel plate 201 by a plurality of fastening bolts; a bolt plate 31 is fixedly installed at the end of the telescopic shaft of the second cylinder 30, and a downward pressure limiting plate 32 is fixedly installed on the bottom surface of the bolt plate 31 by a plurality of fastening bolts, which facilitates the fixed installation operation.

[0034] Specifically, the guide plate 21 is provided with scale lines 211 along the length of the guide plate 21. The rectangular sleeve 25 is fitted onto the guide plate 21. The operator can intuitively adjust the position of the rectangular sleeve 25 on the guide plate 21 along the scale lines 211 according to the specifications of the battery module, and further adjust the position of the positioning plate 24 and the distance between two adjacent positioning plates 24, thereby realizing flexible horizontal positioning of battery modules of different sizes and improving the versatility of the device.

[0035] like Figures 2-4 As shown, a triangular positioning plate 251 is fixedly installed on the top surface of the rectangular sleeve 25, and multiple limiting grooves 33 arranged linearly and equally spaced are provided on the bottom surface of the pressing limiting plate 32. The triangular positioning plate 251 and the limiting grooves 33 are engaged with each other. The cross-sections of the triangular positioning plate 251 and the limiting grooves 33 are both triangular. By using the triangular engagement between the two, the rectangular sleeve 25 can be accurately positioned and firmly pressed, effectively preventing the rectangular sleeve 25 from shifting during the assembly process, and ensuring the accuracy and stability of the battery module positioning.

[0036] Finally, it should be noted that the components such as the first cylinder 20 and the second cylinder 30 involved in this utility model are all general standard parts or components known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a technology known in the art.

[0037] When using the multi-module assembly and positioning device for battery pack of this utility model, the operator first observes the scale line 211 on the guide plate 21 according to the size of the battery module to be assembled, slides the rectangular sleeve 25 along the guide plate 21, and adjusts the position of the positioning plate 24 so that the spacing between adjacent positioning plates 24 is adapted to the specifications of the battery module.

[0038] Next, the limiting component 3 is activated, and the second cylinder 30 drives the lower limiting plate 32 to descend. The limiting groove 33 on the bottom surface of the lower limiting plate 32 engages with the triangular positioning plate 251 on the top surface of the rectangular sleeve 25, firmly pressing the rectangular sleeve 25 in the adjusted position to ensure that the position of the positioning plate 24 is fixed.

[0039] The battery pack casing is then placed on the assembly panel 1, and the pressing assembly 2 is activated. The first cylinder 20 pushes the guide plate 21 and the pressing beam 22 downward. The rubber pad 23 on the bottom surface of the pressing beam 22 contacts the battery pack casing, pressing the casing appropriately to prevent displacement during assembly. At this time, the positioning plate 24 is located above the battery pack casing. According to the position of the positioning plate 24, the battery modules are sequentially assembled into the battery pack casing along the gap between two adjacent positioning plates 24, completing the positioning and installation operation.
