Description

Technical Field

[0001] This utility model relates to the field of battery cell processing technology, specifically to an automatic battery adhesive applicator. Background Technology

[0002] In lithium battery manufacturing, the application process of the battery protection board (PCM) is crucial to the battery's safety and performance. The quality of the PCM adhesive tape application directly affects the battery's insulation performance, structural stability, and long-term reliability. In battery production, the adhesive application process for the PCM is critical to battery performance and safety. Traditionally, PCM adhesive application relies heavily on manual operation. Workers manually place the battery cells with PCM adhesive tape on a workbench and then perform bending and adhesive application sequentially. However, manual operation has limited speed and is easily affected by worker fatigue and skill level, resulting in a low number of cells that can be adhesively applied per unit time, making it difficult to meet the needs of large-scale production. Inaccurate bending angles and uneven adhesive application are common problems during PCM bending and application, thus affecting the performance and reliability of the PCM. Utility Model Content

[0003] The purpose of this invention is to provide an automatic battery adhesive application machine that is highly automated, can effectively improve the efficiency of adhesive application, and ensure the quality of adhesive application.

[0004] An automatic battery adhesive applicator includes a turntable device and a transfer device, a feeding device, a bending device, a first adhesive applicator, and a second adhesive applicator arranged sequentially around the turntable device. A positioning device is mounted above the turntable device, and several clamping devices are installed on the turntable device. The transfer device is used to transfer battery cells with PCM adhesive paper applied on the feeding device to the clamping devices. The clamping devices are used to clamp the battery cells with PCM adhesive paper applied. The positioning device is used to position the battery cells on the clamping devices. The turntable device is used to rotate the clamping devices to a preset position.

[0005] In the above scheme, a transfer device transfers the battery cell with PCM adhesive tape attached from the feeding device to the clamping device. The clamping device holds the battery cell with its front side facing up. The clamping device is mounted on a turntable device, which can rotate the clamping device holding the battery cell to a preset position. This allows the bending device to first bend the protective plate and PCM adhesive on the battery cell, making the PCM adhesive stand up. A first adhesive applicator smooths the PCM adhesive, and a second adhesive applicator applies the PCM adhesive to the back of the battery cell, ensuring that the PCM adhesive is evenly and accurately attached to the battery cell, thus improving the adhesion. The quality of the adhesive application on the battery protection board enhances its performance and reliability. After adhesive application, the battery cells are finally removed by a transfer device. The feeding device, transfer device, bending device, first adhesive application device, and second adhesive application device are sequentially distributed around the turntable device. With the rotation of the turntable device, each process can be carried out continuously and in parallel, effectively increasing the number of battery cells that can be adhesively applied per unit time. The positioning device and clamping device work together to reduce quality problems such as uneven adhesive application and incomplete bending caused by battery cell position deviation or shaking, ensuring product consistency and stability.

[0006] Furthermore, the bending device includes a mounting base and a bending mechanism. A lifting drive assembly is mounted on the mounting base, and the bending mechanism is connected to the lifting drive assembly. The bending mechanism includes a connecting assembly, a rotating drive component, and a rotating bending assembly. The connecting assembly is connected to the lifting drive assembly, and the rotating drive component and the rotating bending assembly are connected to the connecting assembly. The rotating drive component is connected to the rotating bending assembly.

[0007] In the above scheme, the mounting base is installed on the machine platform to provide stable support for the lifting drive assembly and the bending mechanism. The connecting assembly connects the lifting drive assembly and the bending mechanism. In this way, the lifting drive assembly can drive the bending mechanism to freely adjust to a suitable height, realizing the automatic and precise alignment of the bending mechanism. The rotation drive component can drive the rotation bending assembly to rotate, thereby causing the protection board and PCM adhesive on the battery cell to bend.

[0008] Furthermore, the rotating bending assembly includes two rotating connecting rods, a rotating plate, and a rotating shaft. One rotating connecting rod is connected to the rotating drive component, and the other is connected to the connecting assembly. The rotating plate overlaps the two rotating connecting rods, and the end of the rotating shaft is clamped between the rotating connecting rods and the rotating plate. A support plate is installed on the side of the rotating plate away from the turntable device, and a limit push plate is connected to the support plate.

[0009] In the above scheme, the turntable device drives the clamping device after feeding to rotate to the position of the bending device. The support plate installed on the rotating plate can support the battery protection board. The PCM adhesive paper is placed on the limiting push plate, and the limiting push plate can limit the battery protection board. The rotating drive component is used to drive the rotating connecting rod to rotate, which can drive the rotating plate to rotate, thereby driving the limiting push plate and the support plate to rotate. This can bend the PCM adhesive paper and the battery protection board. The bent battery protection board can be supported by the rotating shaft.

[0010] Furthermore, the bending device also includes a limiting mechanism, which includes a mounting plate, a limiting drive assembly, a connecting block, and a limiting block. The mounting plate is mounted on the mounting base, the limiting drive assembly is inclined toward the mounting plate and connected to the mounting plate, the connecting block is mounted on the output end of the limiting drive assembly, and a plurality of the limiting blocks are connected to the connecting block. The limiting blocks are used to abut against the PCM adhesive paper.

[0011] In the above scheme, the mounting plate is installed on the mounting base to realize the modular design of the bending device. The limit drive component is tilted towards the mounting plate, so that the connecting block can be driven to tilt and move up and down at a certain angle. When the bending component is rotated to bend the PCM adhesive paper, the limit drive component will drive the connecting block to descend, so that the limit block tilts and moves towards the PCM adhesive paper. In this way, when bending the PCM adhesive paper, the limit block can abut against the PCM adhesive paper, restricting the PCM adhesive paper from continuing to bend and thus ensuring that the PCM adhesive paper is vertical after bending.

[0012] Furthermore, the first adhesive application device includes an adhesive paper support mechanism and a first adhesive application mechanism. The first adhesive application mechanism includes a first mounting component, a vertical drive component, a horizontal drive component, a first hinge component, and a first roller assembly. The vertical drive component is mounted on the first mounting component, the horizontal drive component is connected to the vertical drive component, the first hinge component is mounted on the output end of the horizontal drive component, and the first roller assembly is connected to the first hinge component.

[0013] In the above scheme, the first adhesive applicator is used to smooth the bent PCM adhesive paper. The first mounting component enables the first adhesive applicator to be stably mounted on the machine platform. The vertical drive component is used to drive the horizontal drive component to move vertically up and down, so that the height of the first adhesive applicator can be flexibly adjusted according to the actual situation, realizing the effective smoothing operation of PCM adhesive paper on different specifications of battery cells, enhancing the versatility and adaptability of the equipment. The horizontal drive component is used to drive the first hinge component connected to the horizontal drive component to move horizontally, thereby driving the first roller component to move back and forth horizontally to smooth the PCM adhesive paper. The adhesive paper support mechanism is used to support the PCM adhesive paper to ensure that the PCM adhesive paper can be stably smoothed.

[0014] Furthermore, the first hinge assembly includes a connecting seat and a hinge seat. The connecting seat is connected to the horizontal drive member, and the hinge seat is connected to the connecting seat. The hinge seat is provided with a plurality of hinge parts. The first roller assembly includes a bracket and an adhesive paper roller. The adhesive paper roller is rotatably mounted on one end of the bracket, and the other end of the bracket is hinged to the hinge parts. Fasteners are connected between the hinge seat and the bracket.

[0015] In the above scheme, the connecting seat enables the hinge seat to be connected to the horizontal drive component. The bracket of the first roller assembly is hinged to the hinge part, so the angle between the bracket and the hinge seat can be adjusted according to the actual production situation. The bracket and the hinge seat are stably connected by fasteners, thereby achieving a stable connection between the first roller assembly and the first hinge assembly. The adhesive paper roller is rotatably connected to one end of the bracket, so that the adhesive paper roller can rotate to smooth the PCM adhesive paper. The rotating adhesive paper roller can reduce the friction between the roller and the adhesive paper, avoiding scratching the adhesive paper or causing wrinkles.

[0016] Furthermore, the second adhesive applicator includes a horizontal sliding module, a vertical sliding module, and a second adhesive applicator mechanism. The vertical sliding module is vertically mounted on the horizontal sliding module. The second adhesive applicator mechanism is connected to the vertical sliding module. The second adhesive applicator mechanism includes a second hinge assembly and a second roller assembly. The second hinge assembly is connected to the vertical sliding module, and the second roller assembly is connected to the second hinge assembly.

[0017] In the above scheme, the horizontal sliding module allows the second adhesive application mechanism to move horizontally. The vertical sliding module is mounted on the horizontal sliding module, and the second adhesive application mechanism is connected to the vertical sliding module, enabling the second adhesive application mechanism to move vertically. For battery cells of different thicknesses or PCM adhesive paper of different heights, the vertical sliding module can flexibly adjust the height of the second adhesive application mechanism, ensuring that the second roller assembly can fully contact the PCM adhesive paper, achieving precise adhesive application, and further improving the versatility and adhesive application effect of the equipment. The presence of the second hinge assembly provides the second roller assembly with an angle adjustment function. In the actual adhesive application process, the shape and bending of the PCM adhesive paper may vary. The second hinge assembly allows the second roller assembly to better fit the adhesive paper surface, thereby achieving a more uniform and effective adhesive application operation and improving the adhesive application quality.

[0018] Furthermore, the second adhesive applicator also includes a first support mechanism and a second support mechanism. The first support mechanism is located below the second adhesive applicator, and the second support mechanism is mounted above the second adhesive applicator. The first support mechanism includes a support base, a first lifting support drive component, and a first adhesive paper support block. The lifting support drive component is mounted on the support base, and the adhesive paper support block is connected to the telescopic end of the lifting support drive component.

[0019] The second support mechanism includes a second lifting support drive, an elastic sliding component, and a second adhesive tape support block. The elastic sliding component is connected to the second lifting support drive, and the second adhesive tape support block is connected to the elastic sliding component.

[0020] In the above scheme, when the second roller assembly applies PCM adhesive to the front of the battery cell, the first support mechanism supports the lower part of the battery cell, and the first lifting support drive can drive the first adhesive support block to rise, forming a stable support for the lower part of the battery cell. This can prevent the battery cell from shaking, displacing or tilting when subjected to roller pressure, ensuring uniform contact between the roller and the PCM adhesive, avoiding problems such as uneven adhesive application and adhesive wrinkles due to battery cell instability, thereby improving the quality and consistency of front adhesive application; when the second roller assembly applies PCM adhesive to the back of the battery cell, the second support mechanism supports the upper part of the battery cell, and the second lifting support drive drives the elastic sliding component and the second adhesive support block to descend, providing support for the upper part of the battery cell. The elastic sliding component provides a certain elastic buffer for the second adhesive support block.

[0021] Furthermore, the clamping device includes a clamping base plate, two sets of sliding side-pushing assemblies and an adjusting plate. The two sets of sliding side-pushing assemblies and the adjusting plate are mounted on the clamping base plate, and the two sets of sliding side-pushing assemblies are respectively located on both sides of the adjusting plate.

[0022] In the above scheme, the sliding side push assembly can slide on the base plate of the clamp. When the battery cell is fed onto the adjustment plate, the sliding side push assembly on both sides of the adjustment plate can clamp the two sides of the battery cell. This design allows the clamping device to flexibly adjust the clamping position according to the actual size and shape of the battery cell.

[0023] Furthermore, the positioning device includes a mounting frame, a pushing positioning mechanism, and several pressing positioning mechanisms. The pushing positioning mechanism and several pressing positioning mechanisms are mounted on the mounting frame and suspended above the turntable device. The pushing positioning mechanism includes a first telescopic member, a second telescopic member, a pushing connecting plate, and a movable push plate. The first telescopic member is vertically connected to the mounting frame, the second telescopic member is horizontally connected to the telescopic end of the first telescopic member, the pushing connecting plate is connected to the telescopic end of the second telescopic member, and the movable push plate is connected to the pushing connecting plate.

[0024] In the above scheme, the battery cell is fed onto the clamping device. The left and right positions are limited by the sliding side push assembly, and the front and back positions are limited by the top push positioning mechanism. The first telescopic member can drive the second telescopic member to move up and down. The second telescopic member can drive the connecting plate to move horizontally, so that the movable push plate can move to abut against the side of the battery cell away from the protection plate. The front and back positions of the battery cell can be adjusted by the movable push plate. Several pressing positioning mechanisms are also installed on the mounting frame. The pressing positioning mechanisms are used to press the battery cell that has moved to the bending device, the first glue application device and the second glue application device, respectively, so as to ensure the stability of the battery cell during the bending and glue application process.

[0025] This utility model discloses an automatic battery adhesive application machine, which features a high degree of automation, effectively improves adhesive application efficiency, and ensures application quality. A transfer device transfers battery cells with PCM adhesive tape applied from the feeding device to a clamping device. The clamping device holds the battery cells with the front side facing up. The clamping device is mounted on a turntable device, which rotates the clamping device holding the battery cells to a preset position. This allows the bending device to first bend the protective plate and PCM adhesive on the battery cell, making the PCM adhesive stand upright. A first application device smooths the PCM adhesive, and a second application device applies the PCM adhesive to the back of the battery cell, ensuring that the PCM adhesive adheres evenly and accurately to the battery cell, thus improving battery protection. The quality of the adhesive application on the board enhances the performance and reliability of the battery protection board. After the adhesive application is completed, the battery cells are finally removed by the transfer device. The feeding device, transfer device, bending device, first adhesive application device and second adhesive application device are sequentially distributed on the outer periphery of the turntable device. With the rotation of the turntable device, each process can be carried out continuously and in parallel, effectively increasing the number of battery cells that can be adhesively processed per unit time. The positioning device and clamping device work together to reduce quality problems such as uneven adhesive application and incomplete bending caused by battery cell position deviation or shaking, ensuring product consistency and stability.

Detailed Implementation

[0038] The present invention provides a battery automatic adhesive applicator in further detail below with reference to specific embodiments and accompanying drawings.

[0039] like Figure 1 and Figure 2 As shown in a preferred embodiment, the automatic battery adhesive applicator of this utility model includes a turntable device 1 and a transfer device 2, a feeding device 3, a bending device 4, a first adhesive applicator 5, and a second adhesive applicator 6 arranged sequentially on the outer periphery of the turntable device 1. A positioning device 7 is mounted above the turntable device 1, and a plurality of clamping devices 8 are installed on the turntable device 1. The transfer device 2 is used to transfer the battery cells with PCM adhesive paper attached on the feeding device 3 to the clamping devices 8. The clamping devices 8 are used to clamp the battery cells with PCM adhesive paper attached. The positioning device 7 is used to position the battery cells on the clamping devices 8. The turntable device 1 is used to rotate the clamping devices 8 to a preset position.

[0040] The battery cells with PCM adhesive tape attached to them are transferred from the feeding device 3 to the clamping device 8 via the transfer device 2. The clamping device 8 holds the battery cells with the front side facing up. The clamping device 8 is mounted on the turntable device 1, which can rotate the clamping device 8 holding the battery cells to a preset position. This allows the bending device 4 to first bend the protective plate and PCM adhesive on the battery cells, making the PCM adhesive stand up. The first adhesive application device 5 then smooths out the PCM adhesive, and the second adhesive application device 6 applies the PCM adhesive to the back of the battery cells. This ensures that the PCM adhesive is evenly and accurately attached to the battery cells, improving battery life. The quality of the adhesive application on the protective plate enhances the performance and reliability of the battery protection board. After the adhesive application is completed, the battery cells are finally removed by the transfer device 2. The feeding device 3, transfer device 2, bending device 4, first adhesive application device 5, and second adhesive application device 6 are sequentially distributed around the turntable device 1. With the rotation of the turntable device 1, each process can be carried out continuously and in parallel, effectively increasing the number of battery cells that can be adhesively processed per unit time. The positioning device 7 and the clamping device 8 work together to reduce quality problems such as uneven adhesive application and incomplete bending caused by battery cell position deviation or shaking, ensuring the consistency and stability of the product.

[0041] like Figures 3 to 5As shown, in some embodiments, the bending device 4 includes a mounting base 41 and a bending mechanism 43. A lifting drive assembly 42 is mounted on the mounting base 41. The bending mechanism 43 is connected to the lifting drive assembly 42. The bending mechanism 43 includes a connecting assembly 431, a rotation drive component 432, and a rotation bending assembly 433. The connecting assembly 431 is connected to the lifting drive assembly 42, and the rotation drive component 432 and rotation bending assembly 433 are connected to the connecting assembly 431 and the rotation drive component 432, respectively. The mounting base 41 is mounted on the machine platform to provide stable support for the lifting drive assembly 42 and the bending mechanism 43. The connecting assembly 431 connects the lifting drive assembly 42 and the bending mechanism 43. Thus, the lifting drive assembly 42 can drive the bending mechanism 43 to freely adjust to a suitable height, achieving automatic and precise alignment of the bending mechanism 43. The rotation drive component 432 can drive the rotation bending assembly 433 to rotate, thereby bending the protection board and PCM adhesive on the battery cell.

[0042] like Figures 3 to 5 As shown, in some embodiments, the rotating bending assembly 433 includes two rotating connecting rods 4331, a rotating plate 4332, and a rotating shaft 4333. One of the rotating connecting rods 4331 is connected to the rotating drive member 432, and the other is connected to the connecting assembly 431. The rotating plate 4332 overlaps the two rotating connecting rods 4331. The end of the rotating shaft 4333 is clamped between the rotating connecting rods 4331 and the rotating plate 4332. A support plate 4334 is installed on the side of the rotating plate 4332 away from the turntable device 1. The support plate 4334 is connected to a limit push plate 4335. The turntable device 1 drives the clamping device 8 after feeding to rotate to the position of the bending device 4. The support plate 4334 installed on the rotating plate 4332 can support the battery protection board. The PCM adhesive paper is placed on the limiting push plate 4335, and the limiting push plate 4335 can limit the battery protection board. The rotating drive component 432 is used to drive the rotating connecting rod 4331 to rotate, which can drive the rotating plate 4332 to rotate, thereby driving the limiting push plate 4335 and the support plate 4334 to rotate. This can bend the PCM adhesive paper and the battery protection board. The bent battery protection board can be supported by the rotating shaft 4333.

[0043] like Figures 3 to 5As shown, in some embodiments, the bending device 4 further includes a limiting mechanism 44. The limiting mechanism 44 includes a mounting plate 441, a limiting drive assembly 442, a connecting block 443, and limiting blocks 444. The mounting plate 441 is mounted on the mounting base 41. The limiting drive assembly 442 is inclined toward the mounting plate 441 and connected to the mounting plate 441. The connecting block 443 is mounted on the output end of the limiting drive assembly 442. A plurality of limiting blocks 444 are connected to the connecting block 443. The limiting blocks 444 are used to abut against the PCM adhesive paper. Mounting plate 441 is mounted on mounting base 41, realizing the modular design of bending device 4. Limiting drive component 442 is inclined towards mounting plate 441, so that connecting block 443 can be driven to tilt and move up and down at a certain angle. When bending component 433 is rotated to bend PCM adhesive paper, limiting drive component 442 will drive connecting block 443 to descend, so that limiting block 444 tilts and moves towards PCM adhesive paper. In this way, when bending PCM adhesive paper, limiting block 444 can abut against PCM adhesive paper, restricting PCM adhesive paper from continuing to bend and thus ensuring that PCM adhesive paper is vertical after bending.

[0044] like Figure 6 and Figure 7 As shown, in some embodiments, the first adhesive applicator 5 includes an adhesive paper support mechanism 51 and a first adhesive applicator 52. The first adhesive applicator 52 includes a first mounting assembly 521, a vertical drive member 522, a horizontal drive member 523, a first hinge assembly 524, and a first roller assembly 525. The vertical drive member 522 is mounted on the first mounting assembly 521, the horizontal drive member 523 is connected to the vertical drive member 522, the first hinge assembly 524 is mounted on the output end of the horizontal drive member 523, and the first roller assembly 525 is connected to the first hinge assembly 524. The first adhesive applicator 5 is used to smooth the bent PCM adhesive paper. The first mounting component 521 enables the first adhesive applicator 52 to be stably mounted on the machine platform. The vertical drive component 522 is used to drive the horizontal drive component 523 to move vertically up and down, so that the height of the first adhesive applicator 52 can be flexibly adjusted according to the actual situation, realizing the effective smoothing operation of PCM adhesive paper on different specifications of battery cells, enhancing the versatility and adaptability of the equipment. The horizontal drive component 523 is used to drive the first hinge component 524 connected to the horizontal drive component 523 to move horizontally, thereby driving the first roller component 525 to move back and forth horizontally to smooth the PCM adhesive paper. The adhesive paper support mechanism 51 is used to support the PCM adhesive paper to ensure that the PCM adhesive paper can be stably smoothed.

[0045] like Figure 6 and Figure 7As shown, in some embodiments, the first hinge assembly 524 includes a connecting seat 5241 and a hinge seat 5242. The connecting seat 5241 is connected to the horizontal drive member 523, and the hinge seat 5242 is connected to the connecting seat 5241. The hinge seat 5242 is provided with a plurality of hinge portions. The first roller assembly 525 includes a bracket 5251 and an adhesive paper roller 5252. The adhesive paper roller 5252 is rotatably mounted on one end of the bracket 5251, and the other end of the bracket 5251 is hinged to the hinge portion. A fastener 53 is connected between the hinge seat 5242 and the bracket 5251. The connecting seat 5241 enables the hinge seat 5242 to be connected to the horizontal drive member 523. The bracket 5251 of the first roller assembly 525 is hinged to the hinge part, so that the angle between the bracket 5251 and the hinge seat 5242 can be adjusted according to the actual production situation. The bracket 5251 and the hinge seat 5242 are stably connected by the fastener 53, thereby realizing the stable connection between the first roller assembly 525 and the first hinge assembly 524. The adhesive paper roller 5252 is rotatably connected to one end of the bracket 5251, so that the adhesive paper roller 5252 can rotate to smooth the PCM adhesive paper. The rotating adhesive paper roller 5252 can reduce the friction between the adhesive paper and the adhesive paper, avoiding scratching the adhesive paper or causing wrinkles.

[0046] like Figure 8 and Figure 9 As shown, in some embodiments, the second adhesive applicator 6 includes a horizontal sliding module 61, a vertical sliding module 62, and a second adhesive applicator 63. The vertical sliding module 62 is vertically mounted on the horizontal sliding module 61. The second adhesive applicator 63 is connected to the vertical sliding module 62. The second adhesive applicator 63 includes a second hinge assembly 631 and a second roller assembly 632. The second hinge assembly 631 is connected to the vertical sliding module 62, and the second roller assembly 632 is connected to the second hinge assembly 631.

[0047] Specifically, the horizontal sliding module 61 allows the second adhesive application mechanism 63 to move horizontally. The vertical sliding module 62 is mounted on the horizontal sliding module 61, and the second adhesive application mechanism 63 is connected to the vertical sliding module 62, enabling the second adhesive application mechanism 63 to move vertically. For battery cells of different thicknesses or PCM adhesive sheets of different heights, the vertical sliding module 62 can flexibly adjust the height of the second adhesive application mechanism 63, ensuring that the second roller assembly 632 can fully contact the PCM adhesive sheet, achieving precise adhesive application and further improving the equipment's versatility and application effect. The presence of the second hinge assembly 631 provides the second roller assembly 632 with an angle adjustment function. In the actual adhesive application process, the shape and bending of the PCM adhesive sheet may vary. The second hinge assembly 631 allows the second roller assembly 632 to better fit the adhesive sheet surface, thereby achieving a more uniform and effective adhesive application operation and improving the application quality.

[0048] like Figure 9 As shown, in some embodiments, the second adhesive applicator 6 further includes a first support mechanism 64 and a second support mechanism 65. The first support mechanism 64 is located below the second adhesive applicator 63, and the second support mechanism 65 is mounted above the second adhesive applicator 63. The first support mechanism 64 includes a support base 641, a first lifting support drive 642, and a first adhesive paper support block 643. The lifting support drive is mounted on the support base 641, and the adhesive paper support block is connected to the telescopic end of the lifting support drive. The second support mechanism 65 includes a second lifting support drive 651, an elastic sliding component 652, and a second adhesive paper support block 653. The elastic sliding component 652 is connected to the second lifting support drive 651, and the second adhesive paper support block 653 is connected to the elastic sliding component 652.

[0049] In the above embodiments, when the second roller assembly 632 applies PCM adhesive to the front of the battery cell, the first support mechanism 64 supports the lower part of the battery cell, and the first lifting support drive 642 can drive the first adhesive support block 643 to rise, forming a stable support for the lower part of the battery cell. This can prevent the battery cell from shaking, displacing or tilting when subjected to roller pressure, ensuring uniform contact between the roller and the PCM adhesive, avoiding problems such as uneven adhesive application and adhesive wrinkles due to battery cell instability, thereby improving the quality and consistency of front adhesive application; when the second roller assembly 632 applies PCM adhesive to the back of the battery cell, the second support mechanism 65 supports the upper part of the battery cell, and the second lifting support drive 651 drives the elastic sliding assembly 652 and the second adhesive support block 653 to descend, providing support for the upper part of the battery cell. The elastic sliding assembly 652 provides a certain elastic buffer for the second adhesive support block 653. During the adhesive application process, the battery cell may undergo slight deformation due to roller pressure. The elastic sliding component 652 can adapt to this deformation, ensuring that the second adhesive support block 653 always maintains good contact and support with the battery cell.

The transfer device 2 retrieves the battery cells with PCM adhesive tape from the feeding device 3 and accurately transfers them to the clamping device 8 on the turntable device 1. The clamping device 8 quickly and reliably clamps the transferred battery cells, ensuring they are in a stable, face-up position. The positioning device 7, located above the turntable device 1, precisely positions the battery cells clamped in the clamping device 8. When the battery... As the turntable rotates to the position of the bending device 4, the bending device 4 bends the protective plate and PCM adhesive on the battery cell, making the PCM adhesive stand upright, preparing for the subsequent adhesive application. The turntable continues to rotate, bringing the battery cell to the first adhesive application device 5. The first adhesive application device 5 starts working, performing preliminary smoothing of the upright PCM adhesive. Driven by the turntable device, the battery cell reaches the position of the second adhesive application device 6. The second adhesive application device 6 further applies the PCM adhesive to the back of the battery cell, ensuring that the PCM adhesive adheres evenly and accurately to the battery cell.
