Description

Technical Field

[0001] This utility model relates to the field of lithium battery assembly technology, and in particular to a novel lithium battery assembly equipment. Background Technology

[0002] With the rapid development of the new energy vehicle and energy storage industries, lithium batteries, as a core power source, have their assembly process precision and efficiency directly affecting the overall performance of the battery pack. Traditional lithium battery assembly equipment generally suffers from the following technical bottlenecks:

[0003] Existing cell arrangement mechanisms mostly use cylinder-driven positioning, leading to misalignment of the cell tabs and affecting subsequent welding quality. This is particularly problematic during pouch cell assembly, where cell expansion exacerbates positioning inaccuracies. Conventional bonding equipment uses single-roller pressing systems, resulting in uneven pressure distribution during tape application, easily causing bubbles and wrinkles, severely impacting heat transfer efficiency between cells. Furthermore, existing welding stations often use fixed fume extraction devices, which reduce dust removal efficiency by over 60% when the welding torch moves, causing metal spatter to deposit on the cell surface and posing a micro-short circuit risk.

[0004] To address the aforementioned issues, the industry has attempted to improve alignment accuracy using visual positioning systems, but this has increased equipment costs. While introducing a double-sided pressing mechanism improves adhesive uniformity, it leads to a larger equipment footprint. Therefore, there is an urgent need to develop a compact lithium battery assembly equipment that integrates high-precision positioning, adaptive bonding, and dynamic dust removal functions to improve production line flexibility while ensuring process quality. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a novel lithium battery assembly equipment, which aims to improve the problems of insufficient cell positioning accuracy, uneven tape coating, poor control of welding fume pollution, and low production line flexibility in existing lithium battery assembly equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a novel lithium battery assembly equipment, including a base, a gripping arm fixedly connected to one side of the upper surface of the base, a support frame fixedly connected to the middle of the upper surface of the base, an adhesive component provided inside the support frame, a welding component provided at the top of the support frame, and an arrangement component provided inside the support frame;

[0007] The adhesive assembly includes two sliding grooves, which are formed on both sides of the inside of the support frame.

A roller is slidably connected between the two limiting plates. An electric push rod is fixedly connected inside the limiting plates. The output end of the electric push rod is fixedly connected to both ends of the roller.

[0008] As a further description of the above technical solution: the welding assembly includes two electric slide rails, which are fixedly connected to the top two sides of the support frame. A support plate is fixedly connected to the outer surface of the electric slide rail, and an electric slide rail is fixedly connected to the lower surface of the support plate. A slide block is fixedly connected to the outer surface of the electric slide rail, and a welding torch is fixedly connected to the outer surface of the slide block.

[0014] As a further description of the above technical solution: an adhesive layer is fixedly connected to the outer surface of the roller two.

[0015] This utility model has the following beneficial effects:

[0016] In this invention, the adhesive ring is vertically positioned by the electric telescopic rod of the adhesive assembly. The circumferential movement of the slide block one drives the roller one and roller two to form a double-roller collaborative pressing system. The electric push rod dynamically adjusts the contact pressure between the adhesive layer of roller two and the cell surface, so as to achieve uniform coating of tape and control of interface bonding strength. It can accurately simulate the influence of different bonding process parameters on the cell packaging quality, and effectively improve the interface consistency and structural reliability of lithium battery assembly.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Reference Figures 1-4 An embodiment of this utility model is provided: a novel lithium battery assembly equipment, including a base 1, a gripping arm 2 fixedly connected to one side of the upper surface of the base 1, a support frame 3 fixedly connected to the middle of the upper surface of the base 1, an adhesive component 4 provided inside the support frame 3, a welding component 5 provided at the top of the support frame 3, and an arrangement component 6 provided inside the support frame 3.

[0026] Casters 9 are fixedly connected to the lower surface of the base 1.

[0027] Specifically, the base 1 serves as the basic support platform for the equipment, and the casters 9 fixedly connected to the lower surface enable the overall workstation transfer. The gripping arm 2 set on one side of the upper surface of the base 1 is responsible for the automated transfer operation of the battery cells. The support frame 3 fixedly connected in the middle of the base 1 provides a three-dimensional working space for the functional components. The bonding component 4 set inside it achieves precise coating of the bonding material on the surface of the battery cells through electric telescopic drive and the synergistic action of double rollers. The welding component 5 installed on the top of the support frame 3 uses a dual-axis slide rail system to control the three-dimensional positioning of the welding gun 505 and integrates air-cooling dust removal function. The arrangement component 6 configured inside the support frame 3 achieves precise alignment and rapid change of the battery cells through the threaded rod 602 transmission mechanism and modular fixtures. Under the integrated layout of the base 1, the various components form a complete battery cell processing production line, realizing continuous operation of positioning, bonding and welding processes in the lithium battery assembly process.

[0028] The adhesive assembly 4 includes two sliding grooves 401, which are formed on both sides of the inside of the support frame 3. An electric telescopic rod 402 is fixedly connected inside the sliding groove 401. A connecting block 403 is fixedly connected to the output end of the electric telescopic rod 402. An adhesive ring 404 is fixedly connected between the two connecting blocks 403. A slide block 405 is slidably connected to the outer surface of the adhesive ring 404. A roller 406 is fixedly connected to one side of the outer surface of the slide block 405. Two limiting plates 407 are fixedly connected to the other side of the outer surface of the slide block 405. A roller 408 is slidably connected between the two limiting plates 407. An electric push rod 409 is fixedly connected inside the limiting plate 407. The output end of the electric push rod 409 is fixedly connected to both ends of the roller 408.

[0029] The outer surface of roller 2 408 is fixedly connected with an adhesive layer 10.

[0030] Specifically, the adhesive assembly 4 includes two sliding grooves 401. The sliding grooves 401 drive the connecting block 403 via a built-in electric telescopic rod 402 to adjust the vertical height of the adhesive ring 404. The slide seat 405 on the outer surface of the adhesive ring 404 drives the roller 406 to guide and unfold the tape. The limiting plate 407 installed on the other side of the slide seat 405 controls the roller 408 to form a tape tensioning mechanism via an internal electric push rod 409. The adhesive layer 10 on the surface of the roller 408 ensures that the tape end is fixed. The linear motion of the output end of the electric push rod 409 is converted into the sliding stroke of the roller 408 between the limiting plates 407, realizing the adaptive adjustment of the pressure between the tape and the surface of the battery cell. The slide seat 405 moves circumferentially along the adhesive ring 404 to cooperate with the double roller system to complete the continuous and uniform coating of the tape on the surface of the battery cell.

[0031] The welding assembly 5 includes two electric slide rails 501, which are fixedly connected to the top two sides of the support frame 3. A support plate 502 is fixedly connected to the outer surface of the electric slide rail 501, and an electric slide rail 503 is fixedly connected to the lower surface of the support plate 502. A slide block 504 is fixedly connected to the outer surface of the electric slide rail 503, and a welding torch 505 is fixedly connected to the outer surface of the slide block 504.

[0032] A fan 7 is fixedly connected to the upper surface of the support plate 502. The input end of the fan 7 is connected to the outside, and the output end of the fan 7 is fixedly connected to the guide pipe 8.

[0033] The output end of the guide tube 8 passes through the support plate 502 and is fixedly connected to the outer surface of the slide block 504.

[0034] Specifically, welding assembly 5 includes two electric slide rails 501. Electric slide rail 501 supports electric slide rail 503 via support plate 502, forming a two-dimensional moving platform. Electric slide rail 503 drives slide base 504 to move welding torch 505 to achieve precise positioning of the welding point. Fan 7 installed on support plate 502 delivers airflow to the working area of ​​welding torch 505 through guide pipe 8. Guide pipe 8 moves synchronously with slide base 504 to ensure that airflow accurately covers the welding part. The coordinated movement of electric slide rail 501 and electric slide rail 503 controls welding torch 505 to complete continuous trajectory welding. The airflow generated by fan 7 is output in a direction through guide pipe 8 to achieve real-time removal of welding fumes and adjustment of the working temperature of welding torch 505. The moving path of slide base 504 and airflow delivery form a dynamic coordination to ensure the stability of welding quality.

[0035] The arrangement assembly 6 includes two motors 601. The motors 601 are fixedly connected to the end of the base 1 away from the gripping arm 2. The output end of the motors 601 is fixedly connected to a threaded rod 602. A groove 603 is provided on the upper surface of the base 1. The threaded rod 602 is rotatably connected inside the groove 603. The outer surfaces of the two threaded rods 602 are respectively threadedly connected to connecting seats 604. A C-shaped plate 605 and a closing plate 606 are slidably connected to the upper surface of the base 1. The C-shaped plate 605 and the closing plate 606 are respectively snapped onto the outer surfaces of the two connecting seats 604.

[0036] The upper surface of the C-shaped plate 605 has multiple slots 607.

[0037] Specifically, the arrangement component 6 includes two motors 601. The motors 601 drive the threaded rod 602 to rotate within the slide groove 603 through their output ends, generating linear driving force. The threaded engagement between the threaded rod 602 and the connecting seat 604 converts the rotational motion into the linear displacement of the connecting seat 604. The C-shaped plate 605 and the closing plate 606 on the upper surface of the base 1 form a linkage mechanism with the connecting seat 604 through a snap-fit ​​method. Multiple slots 607 on the surface of the C-shaped plate 605 provide a positioning reference for the battery cells. The forward and reverse rotation control of the motors 601 drives the C-shaped plate 605 and the closing plate 606 to move towards or away from each other. The rotational support of the slide groove 603 on the threaded rod 602 ensures transmission accuracy. The synchronous displacement of the connecting seat 604 on the threaded rod 602 ensures the alignment accuracy of the C-shaped plate 605 and the closing plate 606. The array design of the slots 607 adapts to the arrangement requirements of battery cells of different specifications.

[0038] Working principle: In use, first move the equipment to the working area using casters 9. Then, select the appropriate size C-shaped plate 605 and closing plate 606 according to actual needs and snap them onto the connecting seat 604. Next, manually place the insulating plate between the battery cells into the slot 607 of the C-shaped plate 605. After the mold is assembled, the gripping arm 2 moves the battery cell into the C-shaped plate 605. Then, the motor 601 drives the threaded rod 602 to rotate, causing the C-shaped plate 605 and closing plate 606 to move towards each other, completing the precise positioning of the battery cell. During the battery cell loading process, manually stretch and fix one end of the tape on roller 406. On the adhesive layer 10 of roller 2 408, the electric telescopic rod 402 drives the adhesive ring 404 to the appropriate working height. The electric push rod 409 dynamically adjusts the distance between roller 2 408 and the outer surface of the battery cell. Then, the slide 1 405 moves circumferentially along the adhesive ring 404 to evenly coat the battery cell surface with tape. After the battery cell is fixed, the welding assembly 5 drives the welding gun 505 to the designated welding coordinates through the electric slide rail 1 501 and the electric slide rail 2 503 for welding. At the same time, the fan 7 blows away the welding fumes in real time through the guide pipe 8 and dissipates heat from the welding gun 505. After welding is completed, the closing plate 606 resets and releases the finished battery cell.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
