Description

Technical Field

[0001] This utility model relates to the field of battery assembly tooling technology, specifically to a battery module suction cup lifting tooling. Background Technology

[0002] In the development of new energy battery modules or packs, to facilitate module installation and handling, we typically need to design corresponding module lifting fixtures. Traditionally, if a module needs to be lifted, a matching lifting structure must be designed on the module to match the lifting fixture. Simultaneously, a frame structure is usually required to ensure reliable connections between the cells, FPC, and connectors within the module. Existing lifting fixtures require matching lifting structures on the module's end plates. To ensure stability during lifting, the matching lifting structure on the module needs sufficient space and specific requirements for the lifting position. This design imposes significant limitations on the module, resulting in limited applicability. When assembling long modules, existing lifting fixtures can cause the cells in the middle of the module to collapse downwards due to gravity, easily leading to cell misalignment or module deformation. Because of variations in cell thickness or arrangement within the module, the lifting fixture may need to be modified, indicating poor compatibility of existing lifting fixtures for module lifting. Existing lifting fixtures have specific weight requirements for lifting modules, making it impossible to adjust the lifting force according to different module weights or achieve compatibility with different module weights. Utility Model Content

[0003] Technical problem to be solved by the utility model

[0004] The technical problem to be solved by this utility model is to provide a battery module suction cup lifting fixture with a simplified structure, reduced risk of damage to internal parts of the module, improved stability of the module during lifting, reduced probability of module misalignment and deformation, good applicability and adjustable pressure.

[0005] Technical solution

[0006] To solve the above problems, the technical solution provided by this utility model is as follows:

[0007] A battery module suction cup lifting fixture includes a long, strip-shaped lifting bracket. Several large adjustment modules are movably connected to the bottom of the lifting bracket along its length. Several small adjustment modules are movably connected to the bottom of the large adjustment modules. Each small adjustment module is equipped with a battery cell suction cup. The battery cell suction cup is connected to a flow generator. The flow generator is connected to a main air inlet valve and a vacuum pump. The flow generator is connected to a gas distribution block. A pressure display is connected inside the gas distribution block.

[0008] Traditional lifting fixtures rely on specific structures of the module end plates (such as lifting matching structures), while this invention uses a cell suction cup to directly adsorb the cell surface, eliminating the need for additional lifting and matching structures in the module design. This breaks through the spatial and positional limitations of module design and significantly improves applicability. Multi-level adjustment of the large and small adjustment modules can accommodate different cell thicknesses and arrangements, solving the problem of frequent changes required by existing fixtures due to cell differences. Preventing module collapse and deformation: The air distribution block and pressure display monitor the air pressure in real time, and adjust the suction force in conjunction with the vacuum equipment to ensure uniform distribution of lifting force, avoiding misalignment or deformation of the middle cell due to gravity when lifting long modules. Weight compatibility optimization: The flow generator and main air inlet valve can dynamically adjust the vacuum suction force according to the module weight, achieving compatible lifting of modules of different weights, solving the problem that traditional fixtures with fixed lifting forces cannot adapt to light / heavy modules.

[0009] Optionally, a lifting ring is provided above the lifting bracket, and the lifting ring is located at the edge of the lifting bracket and has a symmetrical structure.

[0010] The symmetrically arranged lifting rings and side lifting rings ensure that the lifting force points are evenly distributed on both sides of the bracket, avoiding module tilting or excessive local stress caused by traditional single-point lifting. This is especially suitable for long modules, preventing cell misalignment or structural deformation caused by center of gravity shift.

[0011] Optionally, the gas distribution block is provided with multiple gas distribution connectors and is respectively connected to the battery cell suction cup.

[0012] Uniform airflow distribution: Multiple air distribution connectors and air distribution blocks are staggered to ensure that the vacuum adsorption force is evenly transmitted to each cell suction cup along the length of the hanging bracket, avoiding insufficient local adsorption force (such as the middle area of ​​the module) and solving the problem of collapse in the middle of long modules.

[0013] Optionally, the gas distribution blocks are staggered along the length of the hoisting bracket.

[0014] Adaptable to complex cell layouts: The staggered design of the gas distribution blocks can flexibly match the irregular cell layouts within the module, improving compatibility with different module internal structures.

[0015] Optionally, the large adjustment module is fastened to the bottom of the hoisting bracket with screws, and the small adjustment module is fastened to the bottom of the large adjustment module with screws. Both the large adjustment module and the small adjustment module are provided with through holes and connected to the battery cell suction cup.

[0016] The large and small adjustment modules are fixed with screws, enabling quick assembly, disassembly, and position adjustment, simplifying the process of adapting the tooling to different modules. The through-hole design integrates the air passage inside the adjustment module, avoiding the risk of exposed air pipes interfering with hoisting or causing wear, thus improving the reliability of the air passage and the overall compactness of the tooling.

[0017] Optionally, the bottom of the battery cell suction cup is provided with a trumpet-shaped soft disc.

[0018] The trumpet-shaped soft disc can fit the surface of the battery cell with different curvatures, improving the vacuum adsorption sealing performance, while avoiding the hard suction cup from scratching the battery cell (traditional tooling requires the module surface to be flat, which can easily damage the battery cell).

[0019] Alternatively, the disc body may be waist-shaped and positioned along the width of the hoisting bracket.

[0020] The waist-shaped plate is set along the width direction to expand the coverage area of ​​a single suction cup, which is especially suitable for wide or asymmetrically arranged battery cells, reducing the number of suction cups required and lowering costs.

[0021] Optionally, the lifting bracket is provided with symmetrical side lifting rings on its sides.

[0022] The symmetrically arranged lifting rings and side lifting rings ensure that the lifting force points are evenly distributed on both sides of the bracket, avoiding module tilting or excessive local stress caused by traditional single-point lifting. This is especially suitable for long modules, preventing cell misalignment or structural deformation caused by center of gravity shift.

[0023] Beneficial effects

[0024] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0025] The technical solution of this utility model systematically solves the problems of limited module design, intermediate collapse, poor weight compatibility, low operating efficiency and cell damage in the prior art through four core innovations: modular adjustment design, dynamic control of air pressure, symmetrical balance hoisting structure and soft adsorption protection. It significantly improves the versatility, safety and production efficiency of battery module hoisting and is suitable for large-scale manufacturing scenarios of new energy batteries.

[0033] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0034] Example 1

[0035] Combined with appendix Figure 1 , 2 A battery module suction cup hoisting fixture includes a long strip-shaped hoisting bracket 6. In this embodiment, the hoisting bracket 6 is made of a long strip-shaped aluminum alloy profile with a length of 2.5m, a width of 0.3m, a rectangular hollow structure, and an internal air passage reserved.

[0036] Several large adjustment modules 8 are movably connected to the bottom along the length of the hoisting bracket 6. Several small adjustment modules 9 are movably connected to the bottom of the large adjustment modules 8. Each small adjustment module 9 is equipped with a battery suction cup 7. The large adjustment modules 8 are fastened to the bottom of the hoisting bracket 6 with screws, and the small adjustment modules 9 are fastened to the bottom of the large adjustment modules 8 with screws. Both the large adjustment modules 8 and the small adjustment modules 9 are provided with through holes and connected to the battery suction cup 7.

[0037] Combined with appendix Figure 2 The large adjustment module 8 is a strip-shaped steel plate, connected to the bottom of the lifting bracket 6 by screws, and can be detached vertically. The small adjustment module 9 is a rectangular steel plate, vertically fixed to the bottom of the large adjustment module 8 by screws, and can be detached vertically to accommodate battery cells of different thicknesses.

[0038] During use, we can adjust different sliders to match different module lengths. When the thickness of the battery cells within the module varies slightly, we can adjust the small adjustment module 9 of the battery cell suction cup 7 to match modules of different lengths. When the thickness of the battery cells within the module varies slightly, we can use a combination of the large adjustment module 8 and the small adjustment module 9 of the battery cell suction cup 7 for matching, which is very convenient to use in the production process.

[0039] The battery cell suction cup 7 is connected to a flow generator 4, which is connected to a main air inlet valve 2 and a vacuum pump. The flow generator 4 is connected to a gas distribution block 5, and a pressure display 10 is connected inside the gas distribution block 5.

[0040] A lifting ring 11 is provided above the lifting support 6. The lifting ring 11 is located at the edge of the lifting support 6 and has a symmetrical structure. The lifting ring 11 is symmetrically welded to both sides of the top of the support, with two lifting rings 11 on each side, spaced 0.8m apart, for connecting to the crane hook. Symmetrical side lifting rings 12 are provided on the sides of the lifting support 6. One lifting ring is added to each end of the side lifting ring 12 along the length of the support to assist in lifting balance (see...). Figure 3 ).

[0041] Combined with appendix Figure 3 The bottom of the battery cell suction cup 7 is provided with a trumpet-shaped soft disc 703. The disc 703 is waist-shaped and is set along the width direction of the hanging bracket 6. The trumpet-shaped soft disc 703 is made of silicone material, and the bottom opening is waist-shaped (100mm long axis and 60mm short axis), which fits the surface of the battery cell.

[0042] Combined with appendix Figure 4 , 5 The suction cup connector connects to the through hole of the small adjustment module 9 via an internal channel to transmit vacuum suction force. The flow generator 4 connects to an external air source via the main air inlet valve 2 and is connected to a vacuum pump (such as a vacuum pump). The air distribution block 5 is equipped with multiple air distribution connectors 501, which are respectively connected to the battery cell suction cup 7. The air distribution blocks 5 are staggered along the length of the lifting bracket 6. Four air distribution blocks 5 are staggered along the length of the lifting bracket 6, and each air distribution block 5 is equipped with seven air distribution connectors 501, which are respectively connected to the battery cell suction cup 7 via internal channels.

[0043] The pressure display 10 is integrated into the end face of the gas distribution block 5 to monitor the vacuum pressure value of each branch in real time (range -100kPa to 0kPa).

[0044] During module hoisting, the hoisting rope 1 is connected to the hoisting fixture. External equipment such as a gantry crane can lift the entire suction cup fixture and module using the hoisting rope 1. The external air source can be connected to the main air inlet valve 2 connector via an air pipe. The main air inlet valve 2 connector has four branch air outlet connectors, each of which can be connected to a corresponding flow generator 4 via an air pipe. Each flow generator 4 has seven flow generator 4 air outlet connectors, and each flow generator 4 air outlet connector is connected to the battery cell suction cup 7 via an air pipe. This suction cup fixture has a total of 26 battery cell suction cups 7, and each battery cell suction cup 7 is sealed and fitted to the battery cell. Figure 6 As shown.

[0045] After the suction cup fixture and module are installed and fixed, turn on the process generator 4. At this time, the air inside the process generator will be drawn out to form a negative pressure. Since the air outlet 5 of the flow generator 4 and the cell suction cup 77 are connected through the air pipe, the cell suction cup 77 will also form a negative pressure. Each cell suction cup 77 will generate suction force on the cell, thereby achieving the adsorption of the cell and the module can be hoisted.

[0046] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
