Description

Technical Field

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

[0002] In the battery manufacturing industry, the battery cell is the core component of a battery, and its performance and quality directly affect the overall performance and safety of the battery. During the cell production process, double-sided adhesive tape is often applied to the recessed area at the cell head to achieve functions such as fixing the battery protection board. To improve production efficiency and product quality, some companies have begun to use automated equipment for cell adhesive application. However, existing automated adhesive application equipment still has shortcomings in the inspection stage. Although some equipment has certain inspection functions, the inspection methods are not direct or efficient enough, requiring the cells to be transferred from the adhesive application station to a dedicated inspection station. This increases the equipment's footprint and production cycle, reducing production efficiency. Utility Model Content

[0003] The purpose of this invention is to provide an automatic double-sided adhesive tape applicator for battery cells that can improve production efficiency and ensure product quality.

[0004] An automatic double-sided adhesive tape application device for battery cells includes a machine base, a turntable device mounted on the machine base, and a conveying device, an adhesive application device, an adhesive tape feeding feeder, a paper removal device, a transfer platform, and an adhesive tape detection device surrounding the turntable device. The conveying device can transport the battery cell to be coated with double-sided adhesive tape to the turntable device and simultaneously transport the battery cell with double-sided adhesive tape applied to the transfer platform. The adhesive application device is used to absorb the double-sided adhesive tape on the adhesive tape feeding feeder and apply it to the battery cell. The paper removal device is used to peel off the release paper from the applied double-sided adhesive tape. The adhesive tape detection device is used to detect the presence and skewness of the double-sided adhesive tape on the turntable device.

[0005] In the above scheme, the conveying device transports the battery cell to be coated with double-sided tape onto the turntable device. The turntable device clamps the battery cell and sequentially moves it to the tape application device, the release paper removal device, and the detection device. Finally, it returns to its initial position and is transported to the transfer platform by the conveying device. The tape application device can accurately absorb the double-sided tape from the tape feeder and apply it to the designated position on the battery cell. The tape detection device can directly detect the presence and skewness of the double-sided tape on the battery cell on the turntable device, improving the detection efficiency of the battery cell to be coated with double-sided tape, preventing unqualified products from flowing into the next process, and improving the product yield.

[0006] Furthermore, the turntable device includes a turntable drive mechanism, a rotating disk, a clamping mechanism, and an opening clamping mechanism. Several clamping mechanisms are installed on the rotating disk. The clamping mechanisms are used to clamp the battery cells. The opening clamping mechanism is located below the turntable device and is adjacent to the conveying device.

[0007] In the above scheme, the clamping mechanism is adjacent to the conveying device. When the conveying device moves the battery cell to be coated with double-sided adhesive tape to the top of the clamping mechanism, the clamping mechanism drives the clamping mechanism to open. Then, the conveying device places the battery cell on the clamping mechanism. The clamping mechanism loses the force of the clamping mechanism and thus clamps the battery cell. The turntable drive mechanism drives the turntable to rotate. The turntable rotates the clamping mechanism holding the battery cell sequentially to the adhesive application device, the paper tearing device, and the adhesive tape detection device, ensuring the continuity and efficiency of adhesive application.

[0008] Furthermore, the clamping mechanism includes a fixture base plate, a guide rail slider assembly, a sliding plate, and a movable push plate. Several sets of guide rail slider assemblies are mounted on the fixture base plate. The sliding plate is elastically slidably connected to the guide rail slider assembly. The fixture base plate and the rotating disk are provided with sliding grooves corresponding to the positions of the guide rail sliders. The protruding structure of the sliding plate extends out of the sliding groove. The movable push plate is connected to the sliding plate.

[0009] In the above scheme, the fixture base plate and the rotating disk are provided with sliding grooves corresponding to the positions of the guide rail sliders. The protruding structure of the sliding plate extends out of the sliding groove, so that the clamping mechanism can push the protruding structure, causing the sliding plate to slide along the guide rail slider assembly. The sliding plate is generally elastically connected to the guide rail slider assembly through elastic elements such as springs. When the sliding plate is subjected to external force by the clamping mechanism, the spring is quickly compressed, and the movable push plates move away from each other. When the external force disappears, the spring quickly resets, causing the sliding plate to return to its initial position, thereby allowing the movable push plate to clamp the battery cell. This rapid response and reset characteristic enables the equipment to efficiently complete the battery cell loading and clamping operations, improving production efficiency.

[0010] Furthermore, the adhesive tape detection device includes a first support component, a second support component, an adjustment component, a camera component, and a lens component. The adjustment component is mounted on the first support component, the camera component is mounted on the adjustment component, and the lens component is mounted on the second support component. The lens component is adjacent to the turntable device.

[0011] In the above scheme, the first and second support components enable the camera and lens components to stably detect the battery cells on the turntable. The adjustment component is mainly used to adjust the front and rear positions of the camera component. The adjacent layout of the lens component and the turntable allows for rapid detection of the battery cells on the turntable, thereby improving the overall production efficiency and quality of the equipment. The lens component is responsible for focusing the optical image of the adhesive tape on the battery cell and projecting it onto the photosensitive element of the camera component. The camera component converts the received optical image into a digital image signal and analyzes and processes the image using internal image processing algorithms. These algorithms can identify the characteristics of the adhesive tape, such as its outline, position, and color, thereby determining the presence or absence of the adhesive tape and whether there is any skewing.

[0012] Furthermore, the adjustment assembly includes an adjustment screw, a slide table, a slide rail, and a connecting plate. The adjustment screw is rotatably mounted on the first support assembly. One end of the slide table is movably connected to the adjustment screw. The slide table is connected to the slide rail. The connecting plate is mounted on the slide rail. The camera assembly is mounted on the connecting plate.

[0013] In the above scheme, when the adjusting screw is rotated, according to the principle of screw drive, the rotational motion of the screw will be converted into the linear motion of the slide. By controlling the rotation direction and number of rotations of the adjusting screw, the movement position of the slide in the screw axis can be precisely controlled. The slide rail provides precise guidance for the movement of the slide, thereby ensuring the accuracy and stability of the camera assembly when adjusting its position before and after, and ensuring the reliability of the detection results.

[0014] Furthermore, the conveying device includes a mounting frame, a linear drive module, and a mounting base plate. The mounting frame is mounted on the machine base, the linear drive module is mounted on the mounting frame, the mounting base plate is connected to the linear drive module, and several sets of first adsorption mechanisms and second adsorption mechanisms are mounted on the mounting base plate.

[0015] In the above scheme, the mounting frame can ensure the stability of the linear drive module. The linear drive module drives the mounting base plate to move horizontally, thereby driving the first adsorption mechanism and the second adsorption mechanism to move horizontally, so as to realize the loading and unloading of the battery cells.

[0016] Furthermore, the first adsorption mechanism includes a first lifting drive assembly, a first mounting plate, and a first suction cup. The first mounting plate is connected to the first lifting drive assembly, and a plurality of the first suction cups are mounted on the first mounting plate. The second adsorption mechanism includes a first rotation drive assembly, a second lifting drive assembly, a second mounting plate, and a second suction cup. The second lifting drive assembly is connected to the drive end of the first rotation drive assembly, the second mounting plate is connected to the second lifting drive assembly, and a plurality of the second suction cups are mounted on the second mounting plate.

[0017] In the above scheme, the first lifting drive assembly is connected to the first mounting plate, and its function is to provide vertical movement power for the first mounting plate. Several first suction cups are installed on the first mounting plate. When the first mounting plate descends to a suitable position and the first suction cups come into contact with the surface of the battery cell, a negative pressure environment is formed inside the first suction cups to adsorb the battery cell, thereby achieving stable handling of the battery cell. The second adsorption mechanism is mainly used to move the battery cell out of the transfer platform. The first rotation drive assembly can rotate and adjust the position of the battery cell, thereby ensuring that the direction of the battery cell can be adjusted as needed. The second lifting drive assembly can drive the second mounting plate to lift and lower, thereby driving the second suction cups to adsorb and release the battery cell.

[0018] Furthermore, the adhesive applicator includes a robot and an adhesive applicator mechanism. The adhesive applicator mechanism includes a connecting seat, a rotary drive, a rotary connector, an elastic sliding assembly, and an adhesive suction plate. The connecting seat is connected to the execution end of the robot, the rotary drive is connected to the connecting seat, the drive end of the rotary drive passes through the connecting seat and is connected to the rotary connector, the elastic sliding assembly is connected to the rotary connector, and the adhesive suction plate is connected to the elastic sliding assembly.

[0019] In the above solution, the robot can drive the adhesive applicator to pick up double-sided adhesive tape from the adhesive tape feeder and apply it to the designated position on the battery cell. The adhesive applicator is connected to the robot's execution end through the connecting seat. The rotary drive can drive the rotary connector to rotate, and the rotary connector can drive the adhesive tape suction plate to rotate, thereby adjusting the direction of the adhesive tape suction plate to facilitate the adhesive tape suction plate to pick up and apply double-sided adhesive tape. The adhesive tape suction plate is connected to the rotary connector through an elastic sliding component. The elastic sliding component allows the adhesive tape suction plate to adaptively adjust its position to ensure that the double-sided adhesive tape can be evenly and tightly adhered to the surface of the battery cell.

[0020] Furthermore, the paper-tearing device includes a horizontal drive assembly, a third lifting drive assembly, a second rotating drive assembly, a paper-tearing drive component, and clamping plates. The third lifting drive assembly is mounted on the horizontal drive assembly. The second rotating drive assembly is connected to the third lifting drive assembly. The paper-tearing drive component is connected to the second rotating drive assembly. The two clamping plates are respectively connected to the two output ends of the paper-tearing drive component.

[0021] In the above scheme, the horizontal drive component can adjust the horizontal position of the adhesive tearing drive component, the third lifting drive component can adjust the vertical position of the adhesive tearing drive component, and the second rotation drive component can deflect the adhesive tearing drive component, so that the clamp on the adhesive tearing drive component can accurately clamp the release paper on the double-sided adhesive paper, thereby tearing off the release paper. The adhesive tearing device has a high degree of flexibility, ensuring that the release paper on the double-sided adhesive paper can be accurately torn off.

[0022] Furthermore, it also includes a feeding pull belt device and a discharging pull belt device, which are respectively located at both ends of the conveying device, and the discharging pull belt device is arranged adjacent to the transfer platform.

[0023] In the above scheme, the feeding belt device is used to transport the battery cells to be coated with double-sided adhesive tape, and the unloading belt device is used to transport the qualified battery cells. The unloading belt device is adjacent to the transfer platform, which facilitates the transfer of qualified battery cells from the transfer platform to the unloading belt device, and unqualified battery cells are taken out from the transfer platform.

[0024] This utility model discloses an automatic double-sided adhesive tape applicator for battery cells, which has the beneficial effects of improving production efficiency and ensuring product quality. The conveying device transports the battery cells to be coated with double-sided adhesive tape onto a turntable device. The turntable device clamps the battery cells and sequentially moves them to the adhesive application device's application position, the release paper removal device's release paper removal position, and the adhesive tape detection device's detection position. Finally, the cells return to their initial position and are transported to a transfer platform by the conveying device. The adhesive application device accurately absorbs the double-sided adhesive tape from the adhesive tape feeder and applies it to the designated position on the battery cell. The adhesive tape detection device directly detects the presence and skewness of the double-sided adhesive tape on the battery cells on the turntable device, improving the efficiency of inspecting the coated battery cells, preventing defective products from flowing into the next process, and increasing the product yield.

[0034] The following will describe in further detail a device for automatically applying double-sided adhesive tape to battery cells, in conjunction with specific embodiments and accompanying drawings.

[0035] like Figure 1As shown in a preferred embodiment, the present invention provides an automatic double-sided adhesive tape applicator for battery cells, comprising a machine base 1, a turntable device 2 mounted on the machine base 1, and a conveying device 3, an adhesive applicator 4, an adhesive tape feeder 5, a paper-tearing device 6, a transfer platform 8, and an adhesive tape detection device 7 surrounding the turntable device 2. The conveying device 3 can transport the battery cell to be coated with double-sided adhesive tape to the turntable device 2, and simultaneously transport the battery cell with double-sided adhesive tape already applied to the transfer platform 8. The adhesive applicator 4 is used to absorb the double-sided adhesive tape on the adhesive tape feeder 5 and apply it to the battery cell. The paper-tearing device 6 is used to peel off the release paper from the applied double-sided adhesive tape. The adhesive tape detection device 7 is used to detect the presence or absence of double-sided adhesive tape on the turntable device 2 and whether it is skewed.

[0036] After the conveying device 3 transports the battery cell to be coated with double-sided adhesive tape onto the turntable device 2, the turntable device 2 clamps the battery cell and sequentially moves it to the adhesive application device 4, the release paper peeling device 6, and the detection device 7. Finally, it returns to its initial position and is transported by the conveying device 3 to the transfer platform 8. The adhesive application device 4 can accurately absorb the double-sided adhesive tape on the adhesive tape feeder 5 and apply it to the designated position on the battery cell. The adhesive tape feeder 5 is existing technology and will not be described or shown in detail here. The adhesive tape detection device 7 can directly detect the presence and skewness of the double-sided adhesive tape on the battery cell on the turntable device 2, which improves the detection efficiency of the battery cell to be coated with double-sided adhesive tape, prevents unqualified products from flowing into the next process, and improves the product yield.

[0037] like Figure 1 and Figure 2 As shown, in some embodiments, the turntable device 2 includes a turntable drive mechanism 21, a rotating disk 22, a clamping mechanism 23, and an opening clamping mechanism 24. Several clamping mechanisms 23 are mounted on the rotating disk 22 and are used to clamp the battery cells. The opening clamping mechanism 24 is located below the turntable device 2 and is adjacent to the transport device 3. When the transport device 3 transports the battery cell to be coated with double-sided adhesive tape to the area above the clamping mechanism 23, the opening clamping mechanism 24 drives the clamping mechanism 23 to open. Then, the transport device 3 places the battery cell on the clamping mechanism 23, and the clamping mechanism 23 loses the force of the opening clamping mechanism 24, thus clamping the battery cell. The turntable drive mechanism 21 drives the rotating disk 22 to rotate, and the rotating disk 22 sequentially rotates the clamping mechanism 23, which is holding the battery cell, to the adhesive application device 4, the paper-tearing device 6, and the adhesive tape detection device 7, ensuring the continuity and efficiency of the adhesive application process.

[0038] like Figure 3As shown, in some embodiments, the clamping mechanism 23 includes a fixture base plate 231, a guide rail slider assembly 232, a sliding plate 233, and a movable push plate 234. Several sets of guide rail slider assemblies 232 are mounted on the fixture base plate 231. The sliding plate 233 is elastically slidably connected to the guide rail slider assembly 232. The fixture base plate 231 and the rotating disk 22 are provided with sliding grooves corresponding to the positions of the guide rail sliders. The protruding structure 2331 of the sliding plate 233 extends out of the sliding groove. The movable push plate 234 is connected to the sliding plate 233. The fixture base plate 231 and the rotating disk 22 are provided with sliding grooves corresponding to the positions of the guide rail sliders. The protruding structure 2331 of the sliding plate 233 extends out of the sliding groove, allowing the clamping mechanism 24 to push the protruding structure 2331, causing the sliding plate 233 to slide along the guide rail slider assembly 232. This rapid response and reset characteristic enables the equipment to efficiently complete the feeding and clamping operations of the battery cells, improving production efficiency.

[0039] Specifically, the sliding plate 233 is generally elastically connected to the guide rail slider assembly 232 through elastic elements such as springs. When the sliding plate 233 is subjected to the external force of the clamping mechanism 24, the spring is quickly compressed and the movable push plates 234 move away from each other. When the external force disappears, the spring quickly resets and the sliding plate 233 returns to its initial position, so that the movable push plate 234 clamps the battery cell.

[0040] like Figure 1 and Figure 4 As shown, in some embodiments, the adhesive tape detection device 7 includes a first support assembly 71, a second support assembly 72, an adjustment assembly 73, a camera assembly 74, and a lens assembly 75. The adjustment assembly 73 is mounted on the first support assembly 71, the camera assembly 74 is mounted on the adjustment assembly 73, and the lens assembly 75 is mounted on the second support assembly 72. The lens assembly 75 is adjacent to the turntable device 2. The first support assembly 71 and the second support assembly 72 enable the camera assembly 74 and the lens assembly 75 to stably detect the battery cells on the turntable device 2. The adjustment assembly 73 is mainly used to adjust the front and rear positions of the camera assembly 74. The layout design of the lens assembly 75 being adjacent to the turntable device 2 enables the battery cells to be quickly detected on the turntable device 2, thereby improving the overall production efficiency and production quality of the equipment.

[0041] like Figure 4As shown, in some embodiments, the adjustment assembly 73 includes an adjustment screw 731, a slide table 733, a slide rail, and a connecting plate 734. The adjustment screw 731 is rotatably mounted on the first support assembly 71. One end of the slide table 733 is movably connected to the adjustment screw 731, and the slide table 733 is connected to the slide rail. The connecting plate 734 is mounted on the slide rail, and the camera assembly 74 is mounted on the connecting plate 734. When the adjustment screw 731 is rotated, according to the principle of screw drive, the rotational motion of the screw is converted into the linear motion of the slide table 733. By controlling the rotation direction and number of rotations of the adjustment screw 731, the axial movement of the slide table 733 can be precisely controlled. The slide rail provides precise guidance for the movement of the slide table 733, thereby ensuring the accuracy and stability of the camera assembly 74 when adjusting its position, and ensuring the reliability of the detection results.

[0042] like Figure 1 and Figure 5 As shown, in some embodiments, the handling device 3 includes a mounting frame 31, a linear drive module 32, and a mounting base plate 33. The mounting frame 31 is mounted on the machine base 1, the linear drive module 32 is mounted on the mounting frame 31, and the mounting base plate 33 is connected to the linear drive module 32. Several sets of first adsorption mechanisms 34 and second adsorption mechanisms 35 are mounted on the mounting base plate 33. The mounting frame 31 can ensure the stability of the linear drive module 32. Here, the linear drive module 32 can be a standard linear motor. The linear drive module 32 drives the mounting base plate 33 to move horizontally, thereby driving the first adsorption mechanisms 34 and second adsorption mechanisms 35 to move horizontally, so as to realize the loading and unloading of battery cells.

[0043] like Figure 5 As shown, in some embodiments, the first adsorption mechanism 34 includes a first lifting drive assembly 341, a first mounting plate 342, and first suction cups 343. The first mounting plate 342 is connected to the first lifting drive assembly 341, and several first suction cups 343 are mounted on the first mounting plate 342. There are two sets of the first adsorption mechanism 34. One set is mainly used to transport the battery cell to be covered with adhesive tape to the turntable device 2, and the other set is used to transfer the tested battery cell to the transfer platform 8. The first lifting drive assembly 341 is connected to the first mounting plate 342, and its function is to provide vertical movement power for the first mounting plate 342. Several first suction cups 343 are mounted on the first mounting plate 342. When the first mounting plate 342 descends to a suitable position, so that the first suction cups 343 contact the surface of the battery cell, a negative pressure environment is formed inside the first suction cups 343 to adsorb the battery cell, thereby achieving stable transport of the battery cell.

[0044] Specifically, the vacuum adsorption of the first suction cup 343 is usually achieved by a vacuum pump or vacuum generator. The vacuum pump or vacuum generator extracts the air from the first suction cup 343, making the air pressure inside the first suction cup 343 lower than the external air pressure. Under the action of the pressure difference, the first suction cup 343 will tightly adsorb the object to be adsorbed. When it is necessary to release the object, air is introduced into the first suction cup 343 to balance the air pressure inside and outside the first suction cup 343, and the object will separate from the first suction cup 343.

[0045] The second adsorption mechanism 35 includes a first rotation drive assembly 351, a second lifting drive assembly 352, a second mounting plate 353, and a second suction cup 354. The second lifting drive assembly 352 is connected to the drive end of the first rotation drive assembly 351, and the second mounting plate 353 is connected to the second lifting drive assembly 352. Several second suction cups 354 are mounted on the second mounting plate 353. The second adsorption mechanism 35 is mainly used to transport the battery cells from the transfer platform 8. The first rotation drive assembly 351 can rotate to adjust the position of the battery cells, thereby ensuring that the orientation of the battery cells can be adjusted as needed. The second lifting drive assembly 352 can drive the second mounting plate 353 to move up and down, thereby driving the second suction cups 354 to adsorb and release the battery cells.

[0046] like Figure 6 and Figure 7 As shown, in some embodiments, the adhesive applicator 4 includes a robot 41 and an adhesive applicator 42. The adhesive applicator 42 includes a connecting seat 421, a rotary drive 422, a rotary connector 423, a rotary connector 424, and an adhesive suction plate 425. The connecting seat 421 is connected to the execution end of the robot 41, the rotary drive 422 is connected to the connecting seat 421, the drive end of the rotary drive 422 passes through the connecting seat 421 and is connected to the rotary connector 423, the rotary connector 424 is connected to the rotary connector 423, and the adhesive suction plate 425 is connected to the rotary connector 424. The robot 41 can drive the adhesive applicator 42 to pick up double-sided adhesive tape from the adhesive tape feeder 5 and apply it to the designated position on the battery cell. The adhesive applicator 42 and the robot 41 are connected through the connector 421. The rotary drive 422 can drive the rotary connector 423 to rotate. The rotary connector 423 can drive the adhesive tape suction plate 425 to rotate, thereby adjusting the direction of the adhesive tape suction plate 425 to facilitate the adhesive tape suction plate 425 to pick up and apply double-sided adhesive tape. The adhesive tape suction plate 425 is connected to the rotary connector 423 through the rotary connector 424. The rotary connector 424 can make the adhesive tape suction plate 425 adaptively adjust its position to ensure that the double-sided adhesive tape can be evenly and tightly attached to the surface of the battery cell.

[0047] like Figure 7As shown, the rotating connector 424 mainly includes a guide rail, a slider, a spring, a connecting post, and a movable plate. The movable plate is connected to the slider and the connecting post. The slider is connected to the guide rail. The guide rail is installed on the rotating connector 423. The spring is sleeved on the connecting post. When the movable plate is subjected to external force, it will slide along the guide rail and squeeze the spring. In addition to being able to adaptively adjust the position of the adhesive tape suction plate 425, it can also buffer the pressure during adhesive application to a certain extent, preventing damage to the battery cell or adhesive tape due to excessive pressure.

[0048] like Figure 8 As shown, in some embodiments, the paper-tearing device 6 includes a horizontal drive assembly 61, a third lifting drive assembly 62, a second rotating drive assembly 63, a paper-tearing drive component 64, and clamping plates 65. The third lifting drive assembly 62 is mounted on the horizontal drive assembly 61, the second rotating drive assembly 63 is connected to the third lifting drive assembly 62, the paper-tearing drive component 64 is connected to the second rotating drive assembly 63, and the two clamping plates 65 are respectively connected to the two output ends of the paper-tearing drive component 64. The horizontal drive assembly 61 can adjust the horizontal position of the paper-tearing drive component 64, the third lifting drive assembly 62 can adjust the vertical position of the paper-tearing drive component 64, and the second rotating drive assembly 63 can deflect the paper-tearing drive component 64, so that the clamping plates 65 on the paper-tearing drive component 64 can accurately clamp the release paper on the double-sided adhesive paper, thereby tearing off the release paper. The paper-tearing device 6 has a highly flexible structure, ensuring that the release paper on the double-sided adhesive paper can be accurately torn off.

[0049] like Figure 1 As shown, in some embodiments, a feeding pull belt device 9 and a discharging pull belt device 10 are also included. The feeding pull belt device 9 and the discharging pull belt device 10 are respectively located at both ends of the conveying device 3, and the discharging pull belt device 10 is arranged adjacent to the transfer platform 8. The feeding pull belt device 9 is used to transport the battery cells to be coated with double-sided adhesive tape, and the discharging pull belt device 10 is used to transport the qualified battery cells. The discharging pull belt device 10 is adjacent to the transfer platform 8, which facilitates the transfer of qualified battery cells from the transfer platform 8 to the discharging pull belt device 10. The transfer can be achieved by the second adsorption mechanism 35, and unqualified battery cells are taken out from the transfer platform 8.

[0050] This utility model discloses the working principle and process of an automatic double-sided adhesive tape applicator for battery cells. The transport device 3 transports the battery cell to be coated with double-sided adhesive tape onto the turntable device 2. The clamping mechanism 24 drives the clamping mechanism 23 to open its clamps. The transport device 3 then places the battery cell onto the clamping mechanism 23, which then loses the force of the clamping mechanism 24 and clamps the battery cell. The turntable drive mechanism 21 drives the rotating disk 22 to rotate. The rotating disk 22 rotates the clamping mechanism 23, which holds the battery cell, sequentially to the adhesive application device 4, the paper removal device 6, and the adhesive tape detection device 7. The adhesive application device 4 accurately absorbs the double-sided adhesive tape from the adhesive tape feeder 5 and applies it to the designated position on the battery cell. The paper removal device 6 removes the release paper from the double-sided adhesive tape. The adhesive tape detection device 7 directly detects the presence and skewness of the double-sided adhesive tape on the battery cell on the turntable device 2, improving the detection efficiency of the battery cell with double-sided adhesive tape.

[0051] In the description of this utility model, it should be understood that terms such as "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0052] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.
