Description

Technical Field

[0001] This application relates to the field of tab bonding technology, and in particular to a tab bonding device and production line. Background Technology

[0002] Existing battery tabs are composed of two parts: an adhesive strip and a metal strip. The adhesive strip needs to be bonded to both sides of the metal strip to prevent short circuits between the metal strip and the aluminum-plastic film during battery encapsulation. Unlike conventional post-soldering adhesive application, the tab manufacturing process for some soft-pack lithium batteries, high-current power cells, and laminated cells requires applying insulating adhesive first, followed by ultrasonic welding of the tabs.

[0003] Currently, Chinese invention patent application CN219513154U, published on August 11, 2023, proposes a tab-applying device, comprising the following structure: a feeding mechanism, a transfer mechanism, and an adhesive applicator. The transfer mechanism and the adhesive applicator are mounted on the feeding mechanism. The transfer mechanism includes a conveying component and a clamping component. The conveying component and the clamping component are mounted on the conveying component. The adhesive applicator includes a driving component, a heat-bonding component, and a fixing component. The driving component and the fixing component are mounted on the feeding mechanism, and the heat-bonding component is located at the free end of the driving component. The fixing component secures the metal strip.

[0004] In use, the tape roll is placed on the feeding mechanism to release the tape strip; the tape strip is threaded through the transfer mechanism, clamped by the clamping component, and conveyed by the conveying component. The drive component drives the heat-bonding component to contact the tape strip, enabling the heat-bonding component to heat the tape and stabilize it on the metal strip.

[0005] Regarding the aforementioned technologies, after the adhesive application process is completed on the metal strip, operators typically need to manually or with the aid of specialized auxiliary equipment cut the continuous adhesive strip at designated locations. This step is crucial for ensuring the accuracy of subsequent processes and the dimensional specifications of the final product. The cutting length and cross-sectional quality must be precisely controlled according to actual production requirements to guarantee the bonding effect and overall consistency of the metal strip in subsequent processing or assembly stages. Summary of the Invention

[0006] This application provides a tab-applying device and production line. When the tape cutting component is working, the tape pressing component presses one end of the tape, the tape pulling component presses the other end of the tape, the adsorption component adsorbs the tape, and then the tape is cut so that the tape length is the same each time, ensuring the accuracy of subsequent processes and the dimensional specifications of the final product.

[0007] An electrode tab adhesive device, comprising: Frame, tab feeding assembly, tape feeding assembly and adhesive application assembly; The electrode feeding assembly includes at least one electrode unwinding roller and several electrode passing rollers. The electrode unwinding roller is rotatably mounted at one end of the frame, and the electrode passing rollers are rotatably mounted on the frame. The tape feeding assembly includes two tape unwinding rollers and several tape feed rollers, and the tape unwinding rollers and tape feed rollers are rotatably mounted on the frame; The adhesive application assembly includes an adhesive pressing component, an adhesive pulling component, an adhesive cutting component, an adsorption component, and a two-axis power component. The fixed ends of the adhesive pressing component, the adhesive pulling component, the adhesive cutting component, and the two-axis power component are mounted on the frame, and the adsorption component is mounted on the free end of the two-axis power component.

[0008] By adopting the above technical solution, during adhesive application, a disc-shaped electrode lug roll is installed onto the electrode lug unwinding roller. The electrode lug roll is then broken, allowing it to pass through an area composed of several electrode lug guide rollers, ensuring the electrode lug is horizontal. Upon contact with the electrode lug guide rollers, a disc-shaped adhesive tape roll is installed onto the adhesive tape unwinding roller. The adhesive tape roll is then broken, allowing it to pass through an area composed of several adhesive tape guide rollers, allowing the adhesive tape to penetrate into the pressing component. The adhesive tape is horizontal and perpendicular to the electrode lugs. The adhesive pulling component horizontally pulls the adhesive tape, causing it to extend a certain distance beyond the end of the pressing component. The pressing component then tightens the adhesive tape. The two-axis power component is operated to move the suction component horizontally to a position matching the adhesive tape pulled out by the pulling component. Finally, the two-axis power component is operated to move the suction component vertically towards the adhesive tape. The adhesive tape comes into contact with the filter, and the adsorption component is controlled to hold the tape in place. The cutting component then cuts the tape. The two-axis power unit is controlled to move the adsorption component away from each other, separating the two tapes. Next, the two-axis power unit moves the adsorption component horizontally above the tab tape. Then, the two-axis power unit moves the adsorption component along the height direction towards the tab tape, attaching the tape to the tab tape. The adsorption component stops working, and the two-axis power unit moves it in the opposite direction along the height direction to complete the application. During the cutting component's operation, the pressing component presses one end of the tape, the pulling component presses the other end, and the adsorption component holds the tape in place. The tape is then cut, ensuring that each cut is of the same length and at the same location. This ensures the accuracy of subsequent processes and the dimensional specifications of the final product, precisely controlling the cutting length and cross-sectional quality to guarantee the bonding effect and overall consistency of the metal strip in subsequent processing or assembly.

[0009] Optionally, the pressing component includes a pressing mounting plate, two pressing power components, and a pressing plate. The pressing mounting plate is mounted on the frame. The fixed ends of the two pressing power components are mounted on the pressing mounting plate, and the pressing plate is mounted on the free ends of the pressing power components. The pressing mounting plate has two receiving grooves and two tape through grooves. The tape through grooves are connected to the corresponding receiving grooves, and the pressing plate is slidably mounted in the tape through grooves. The glue-pulling component includes a glue-pulling power component and a finger cylinder. The fixed end of the glue-pulling power component is disposed on the frame, and the finger cylinder is disposed on the free end of the glue-pulling power component. The rubber cutting component includes a rubber cutting power component and a first cutter. The fixed end of the rubber cutting power component is disposed on the frame, and the first cutter is disposed on the free end of the rubber cutting power component.

[0010] By adopting the above technical solution, during use, the tape end passes through the tape groove. The pulling force component moves, causing the finger cylinder to move, so that the tape end enters the area between the two fingers of the finger cylinder. The finger cylinder clamps the two tape ends. The pulling force component moves in the opposite direction, causing the finger cylinder to stretch the tape to a preset position. The pressing force component operates, causing the pressing plate to contact the tape downwards, pressing the tape firmly against the pressing mounting plate, keeping the tape horizontal. After the adsorption component adsorbs the tape, the cutting force component operates, causing the first cutter to cut the tape, forming a new tape end. The finger cylinder and pressing plate tighten the tape, facilitating the adsorption component's adsorption of the tape, and ensuring the tape is horizontal and wrinkle-free, guaranteeing subsequent adhesive application quality. Furthermore, the tightened tape facilitates the first cutter's cutting, improving work efficiency.

[0011] Optionally, the assembly also includes a heat-bonding component, which includes a tab preheating component. The tab preheating component includes two tab preheating plates distributed vertically. The tab preheating plates are mounted on the frame. The tab preheating component is positioned between the tab feeding component and the adhesive bonding component.

[0012] By adopting the above technical solution, after the tab belt extends out of the tab roller area, it moves along a predetermined path, passing through the gap between two symmetrically arranged tab preheating plates. The two sides of the tab belt will make stable contact with the tab preheating plates, thus receiving uniform heat conduction from them. This not only ensures that the tab belt remains horizontal and stable during transport, avoiding mounting errors caused by sagging or offset, but also effectively increases the material temperature and activity of the tab belt itself through continuous preheating. Subsequently, when the adsorption component precisely applies the tape to the tab belt, because the tab belt has been fully preheated, its surface temperature is high, which significantly enhances the initial adhesion and wettability of the tape, thereby ensuring a stronger and more uniform bonding effect between the tape and the tab belt, providing a reliable connection foundation for subsequent processes.

[0013] Optionally, the heat bonding assembly further includes a pre-melting assembly, which includes two pre-melting plates distributed vertically and a pre-melting power component. The fixed end of the pre-melting power component is disposed on the frame, one pre-melting plate is disposed on the frame, and the other pre-melting plate is disposed on the free end of the pre-melting power component. The pre-melting assembly is disposed on the side of the adhesive bonding assembly away from the tab strip preheating assembly.

[0014] By adopting the above technical solution, after the tabs are applied, they pass through the area composed of two pre-melted plates. The pre-melting power component is controlled to work, causing the two pre-melted plates to clamp the tape and the tabs. The pre-melted plates are heated to about 130°C, causing the surface material of the tape to melt and thus firmly adhere to the surface of the tabs. During this process, continuous extrusion using high temperature and pressure helps to effectively remove air bubbles that may exist between the two layers of tape and at the contact surface between the tape and the tabs, ensuring a uniform and gapless bonding interface and improving the overall reliability and consistency of the adhesion.

[0015] Optionally, the heat-bonding assembly further includes a heat-pressing assembly, which includes two heat-pressing plates distributed vertically and a heat-pressing power component. The fixed end of the heat-pressing power component is disposed on the frame, one heat-pressing plate is disposed on the frame, and the other heat-pressing plate is disposed on the free end of the heat-pressing power component. The heat-pressing assembly is disposed on the side of the pre-melting assembly away from the adhesive bonding assembly.

[0016] By adopting the above technical solution, the tabs and tape are preheated and melted before being conveyed to a working area consisting of two hot press plates. The hot press power unit is controlled to clamp the tape and tabs between the two plates. The temperature of the hot press plates is controlled at approximately 150°C, causing the surface material of the already melted tape to soften and even partially melt again. This allows the tape to fully fill the tiny unevenness on the surface of the tabs under pressure, achieving a firm and uniform bond. This process divides the tape melting process into two steps: first, pre-melting initially fixes and removes air bubbles between the adhesive layer and the tabs, avoiding adhesion defects; then, final hot pressing is completed under precise temperature and pressure control, ensuring a regular shape and tight edge adhesion. This step-by-step process not only improves overall work efficiency but also significantly enhances the reliability and appearance consistency of the bonding, effectively guaranteeing the sealing and insulation performance during subsequent battery module assembly.

[0017] A production line includes the tab attaching device and a tab moving assembly. The tab moving assembly includes a moving component, which includes two moving clamping plates, two moving clamping power components, and a moving power component. The fixed end of the moving power component is disposed on the frame, the fixed end of the moving clamping power component is disposed on the free end of the moving power component, and the moving clamping plates are disposed on the free end of the moving clamping power component.

[0018] By adopting the above technical solution, after the tab tape and adhesive tape are hot-pressed, they pass through the area composed of two moving clamping plates. After each application of adhesive, the movement of the moving clamping power component is controlled, causing the moving clamping plates to clamp the tab tape. The hot pressing plate and pre-melting plate are controlled to move away from the tab tape, and the moving power component is controlled to move horizontally away from the tab feeding assembly, causing the moving clamping plates to pull the tab tape, pulling the same distance each time. The hot pressing plate and pre-melting plate are controlled to clamp the tab tape and adhesive tape, and the moving clamping power component is controlled to move in the opposite direction, causing the moving clamping plate to move away from the tab tape. The moving power component is then controlled to work in the opposite direction, causing the moving clamping plate to reset, thus completing a complete work cycle. This process is automatic, precise, and cyclical, effectively ensuring the stability and consistency of tab tape application and conveying.

[0019] Optionally, the system further includes a detection component, which includes a first deformable metal plate (the same number as the number of tab unwinding rollers), a second deformable metal plate (the same number as the number of tab unwinding rollers), a detection power unit, and an alarm. The first deformable metal plate, the fixed end of the detection power unit, and the alarm are mounted on the frame. The second deformable metal plate is mounted on the free end of the detection power unit. The first deformable metal plate and the second deformable metal plate are respectively electrically connected to the alarm.

[0020] By adopting the above technical solution, after the tab tape and adhesive tape are hot-pressed together, they pass through the detection area between the first and second deformable metal plates. Before the detection begins, the moving clamping plate moves away from the tab tape. During detection, the detection power component is controlled to push its free end out, causing the second deformable metal plate to abut against the area of ​​the tab tape without adhesive, and causing the tab tape to move slightly, thus bringing the adhesive-attached part into contact with the first deformable metal plate. If there is a missing adhesive layer or incomplete adhesion at the adhesive application point, the first deformable metal plate will directly contact the tab tape substrate. At this time, a closed conductive circuit will be formed between the first deformable metal plate, the tab tape itself, and the second deformable metal plate, triggering the alarm to activate and emit an audible and visual alarm signal, promptly alerting the operator to the problem of poor adhesion. This detection mechanism achieves online, real-time, and non-destructive monitoring of adhesive layer integrity, effectively preventing defective products from flowing into the next process and avoiding subsequent process defects caused by missing, misaligned, or improperly adhered adhesive tape, significantly improving the consistency of the tabs and the overall reliability of the product.

[0021] Optionally, it also includes a slitting assembly, which includes a second cutter, a cutter power component, and a slitting moving power component. The fixed end of the slitting moving power component is disposed on the frame, the fixed end of the cutter power component is disposed on the free end of the slitting moving power component, the second cutter is disposed on the free end of the cutter power component, and the slitting assembly is disposed on the side of the tab moving assembly away from the tab feeding assembly.

[0022] By adopting the above technical solution, when the hot press plate and pre-melted plate clamp the tabs and adhesive tape, the slitting and moving power component is controlled to drive the cutting power component and the second cutting blade to move as a whole, precisely positioning them to the preset tape slitting position. Subsequently, the cutting power component is activated, pushing the second cutting blade to perform the cutting action, efficiently cutting the adhesive tape between multiple connected tabs. This process achieves rapid separation of multiple tabs after simultaneous adhesive application, ensuring not only neat and consistent cuts but also facilitating independent winding or further processing of subsequent products, thereby improving the continuity and automation level of the overall production process.

[0023] Optionally, the slitting assembly further includes a light-shielding sensor disposed at the free end of the slitting moving power member.

[0024] By employing the above technical solution, when the hot press plate and the pre-melting plate work together to clamp and fix the tab tape and the adhesive tape, the slitting moving power component is activated. A light-blocking sensor detects the passing tab tape and records its light-blocking time. Combined with the real-time moving speed of the free end of the slitting moving power component, the actual measured width of the tab tape is accurately calculated using the relationship between time and speed. Subsequently, this calculated width is compared and verified with the preset standard width of the tab tape to determine whether the tab tape has experienced positional shift or angular deviation during transmission. This effectively achieves real-time monitoring and quality inspection of the tab tape alignment, ensuring the accuracy and stability of the slitting process.

[0025] Optionally, the assembly further includes a tape shaping component located on the side of the slitting assembly away from the tab moving component. The tape shaping component includes a tape hot-melt component, a cold-press shaping component, and a tape consolidation component arranged sequentially. The tape hot-melt component, the cold-press shaping component, and the tape consolidation component are mounted on the frame.

[0026] By adopting the above technical solution, the slit tape and tab tape are passed through the working areas of the tape hot-melt component, cold-press shaping component, and tape consolidation component. The hot-melt component operates at a temperature of 240°C, melting the tape to fully soften it and give it good fluidity, allowing it to make close contact with the tab tape surface and fuse with it. The cold-press shaping component applies stable pressure at a low temperature, causing the tape to quickly solidify on the tab tape and form a preliminary shape, preventing the tape from shifting or deforming in subsequent processes. The tape consolidation component performs final treatment on the composite part at a controlled temperature. The area in contact with the tab tape is maintained at a temperature of approximately 150°C, while the area in contact with the tape is set at approximately 140°C. Through differentiated temperature control, the tab tape is kept from thermal damage at a suitable temperature, and the mutual penetration and fusion of tape molecules and substrate are further promoted, thereby significantly strengthening the tape's adhesion and interfacial bonding strength, ensuring a durable and reliable fusion effect. The bonding quality of the tape on the electrode tab surface was optimized. By controlling the temperature and pressure in stages, a strong and uniform adhesive structure was formed between the tape and the electrode tab.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. In this invention, during the operation of the adhesive cutting component, the pressing component presses one end of the adhesive tape, the pulling component presses the other end of the adhesive tape, and the adsorption component adsorbs the adhesive tape before cutting. This ensures that the adhesive tape cut each time is of the same length and at the same cutting position. This ensures the accuracy of subsequent processes and the dimensional specifications of the final product, precisely controlling the cutting length and cross-sectional quality, thereby guaranteeing the bonding effect and overall consistency of the metal strip in subsequent processing or assembly stages.

[0028] 2. The slitting component of this invention employs a light-shielding sensor and utilizes the relationship between time and speed to accurately calculate the actual measured width of the current tab tape. Subsequently, this calculated width is compared and verified with a preset standard tab tape width to determine whether the tab tape has experienced positional shift or angular deviation during transmission. This effectively enables real-time monitoring and quality inspection of the tab tape alignment, ensuring the accuracy and stability of the slitting process.

[0029] 3. This invention, through the use of a tape shaping component and differentiated temperature control, not only prevents thermal damage to the tab tape at a suitable temperature but also further promotes the mutual penetration and fusion of tape molecules and the substrate. This significantly enhances the tape's adhesion and interfacial bonding strength, ensuring a durable and reliable fusion effect. The composite quality of the tape on the tab tape surface is optimized; by controlling temperature and pressure in stages, a strong and uniform adhesive structure is ensured between the tape and the tab tape.

[0042] refer to Figure 3 and 4 The adhesive-pulling component 420 includes an adhesive-pulling power component 421 and a finger cylinder 422. The fixed end of the adhesive-pulling power component 421 is mounted on the adhesive applicator 460, and the finger cylinder 422 is mounted on the free end of the adhesive-pulling power component 421. The output end of the central processing unit is electrically connected to the adhesive-pulling power component 421 and the finger cylinder 422.

[0043] refer to Figure 3 and 4 The two-axis power unit 450 includes a horizontal moving power component 451 and a vertical moving power component 452.

The adsorption component 440 is mounted on the free end of the vertical moving power component 452. The output end of the central processing unit is electrically connected to the horizontal moving power component 451, the vertical moving power component 452, and the adsorption component 440. The adsorption component 440 is a vacuum adsorption device.

[0044] refer to Figure 3 and 4The tape feeding assembly 300 includes two tape unwinding rollers 310, several tape feed rollers 320, a tape holder 330, a track 340, two counterweight rollers 350, two sliders 360, and a limiting plate 370. The tape holder 330 is mounted on the applicator 460. The tape unwinding rollers 310 and the tape feed rollers 320 are connected to the tape holder 330 by bearings. The track 340 is mounted on the applicator 460. The sliders 360 are slidably disposed on the track 340. The counterweight rollers 350 are connected to the sliders 360 by bearings. A limiting baffle for the counterweight rollers 350 to stretch the tape is installed on the track 340. Two limiting plates 370 are installed on some of the tape feed rollers 320 and the counterweight rollers 350 to limit the tape movement.

[0045] refer to Figure 3 and 4 The disc-shaped tape roll is installed onto the tape unwinding roller 310, the tape roll is broken and passed through the area composed of several tape passing rollers 320, and contacts the lower side of the counterweight roller 350, and is located within two adjacent limiting plates 370, so that the tape passes through the tape groove 4112, and the end of the tape passes beyond the tape groove 4112. The pressing plate 413 contacts the tape downward and presses the tape with the pressing mounting plate 411.

[0046] refer to Figure 3 and 4 During adhesive application, the central processing unit (CPU) controls the movement of the adhesive-pulling power component 421, causing the finger cylinder 422 to move. This allows the ends of the adhesive tape to enter the area between the two fingers of the finger cylinder 422. The CPU controls the finger cylinder 422 to clamp the ends of the two adhesive tapes. The CPU controls the adhesive-pressing power component 412 to operate, causing the pressure plate 413 to move away from the adhesive tape. The CPU controls the adhesive-pulling power component 421 to move in the opposite direction, causing the finger cylinder 422 to stretch the adhesive tape to a preset position. When the tape is stretched, it drives the tape roller 320 and the tape unwinding roller 310 to rotate. The tape drives the counterweight roller 350 to rotate and move simultaneously. The counterweight roller 350 drives the slider 360 to move along the track 340. The CPU controls the adhesive-pressing power component 412 to operate, causing the pressure plate 413 to contact the tape downwards and press the tape against the adhesive-pressing mounting plate 411, keeping the tape horizontal. Under the action of its own gravity and the pressing action of the adhesive mounting plate 411, the counterweight roller 350 stretches the tape until the counterweight roller 350 drives the tape to contact the limit baffle.

[0047] refer to Figure 3 and 4The central processing unit controls the horizontal moving power component 451 to move, so that its free end drives the vertical moving power component 452 and the adsorption component 440 to move above the tape. The central processing unit controls the vertical moving power component 452 to move, so that its free end drives the adsorption component 440 to move closer to the tape and contact the tape. The central processing unit controls the adsorption component 440 to work and adsorb the tape.

[0048] refer to Figure 3 and 4 The central processing unit (CPU) controls the cutting power component 431 to cause the first cutter 432 to cut the tape, forming a new tape end. The CPU controls the vertical moving power component 452 and the horizontal moving power component 451 to move in opposite directions, causing the adsorption component 440 to move the two tapes away from each other in the vertical direction, and then move them horizontally above the tabs. The CPU controls the vertical moving power component 452 to move the adsorption component 440 to move the tapes closer to the tabs, attaching the tapes to the tabs. The CPU then shuts off the adsorption component 440 and controls the vertical moving power component 452 to move the adsorption component 440 away from the tabs.

[0049] refer to Figure 3 and 4 The tape stretching process is divided into two stages by the synergistic action of the counterweight roller 350 and the finger cylinder 422: the first stage involves initial traction and positioning by the finger cylinder 422, while the second stage utilizes the counterweight roller 350 to provide continuous and stable tension under gravity. This two-stage stretching method not only ensures that the tape maintains appropriate tension and flatness before application but also effectively avoids problems such as tape loosening, misalignment, or breakage that may occur due to one-time stretching, thereby improving the accuracy and reliability of the application process.

[0050] refer to Figure 3 and 4 The finger cylinder 422 and the pressure plate 413 tighten the tape, facilitating the adsorption component 440 to adsorb the tape, ensuring the tape is horizontal and wrinkle-free, guaranteeing the quality of subsequent adhesive application. The tightened tape also facilitates the first cutter 432's cutting, improving work efficiency. This ensures that each cut produces tape of the same length and at the same location. It guarantees the precision of subsequent processes and the dimensional specifications of the final product, accurately controlling the cutting length and cross-sectional quality, thereby ensuring the bonding effect and overall consistency of the metal strip in subsequent processing or assembly stages.

[0051] refer to Figure 2 and 5The heat-bonding assembly 500 includes an electrode tab preheating assembly 510, a pre-melting assembly 520, and a hot-pressing assembly 530. The electrode tab preheating assembly 510, the pre-melting assembly 520, and the hot-pressing assembly 530 are mounted on the frame 100. The electrode tab preheating assembly 510 is disposed between the electrode tab feeding assembly 200 and the adhesive bonding assembly 400. The pre-melting assembly 520 and the hot-pressing assembly 530 are sequentially disposed on the rear side of the adhesive bonding assembly 400.

[0052] refer to Figure 2 The tab preheating assembly 510 includes two tab preheating plates 511 distributed vertically, a tab preheating frame 512, a tab preheating power component 513, and a tab guide plate 514. The tab preheating frame 512 is mounted on the frame 100. The tab guide plate 514 is provided with the same number of guide grooves as the tabs and is mounted on the tab preheating frame 512. The fixed end of the tab preheating power component 513 is mounted on the tab preheating frame 512. One tab preheating plate 511 is mounted on the tab preheating frame 512, and the other tab preheating plate 511 is mounted on the free end of the tab preheating power component 513. The output end of the central processing unit is electrically connected to the tab preheating plate 511 and the tab preheating power component 513.

[0053] refer to Figure 5 The pre-melting assembly 520 includes two pre-melting plates 521 distributed vertically, a pre-melting power component 522, and a pre-melting frame 523. The pre-melting frame 523 is mounted on the frame 100. The fixed end of the pre-melting power component 522 is mounted on the pre-melting frame 523. One pre-melting plate 521 is mounted on the pre-melting frame 523, and the other pre-melting plate 521 is mounted on the free end of the pre-melting power component 522. The output end of the central processing unit is electrically connected to the pre-melting plate 521 and the pre-melting power component 522.

[0054] refer to Figure 5 The hot pressing assembly 530 includes two hot pressing plates 531 distributed vertically, a hot pressing power component 532, a hot pressing bracket 533, and two hot pressing rollers 534. The hot pressing bracket 533 is mounted on the frame 100. The fixed end of the hot pressing power component 532 is mounted on the hot pressing bracket 533. One hot pressing plate 531 is mounted on the hot pressing bracket 533, and the other hot pressing plate 531 is mounted on the free end of the hot pressing power component 532. The hot pressing rollers 534 are bearing mounted on the hot pressing bracket 533. The output end of the central processing unit is electrically connected to the hot pressing plates 531 and the hot pressing power component 532.

[0055] refer to Figure 5The tab belt sequentially passes through the area comprised of two tab preheating plates 511, two pre-melting plates 521, two hot press rollers 534, and two hot press plates 531. The tab belt then passes through the guide groove on the tab guide plate 514. When the tab belt is stationary, the central processing unit controls the movement of the corresponding power components, causing the tab belt to contact the two tab preheating plates 511, two pre-melting plates 521, and two hot press plates 531. Both sides of the tab belt maintain stable contact with the tab preheating plates 511, thus receiving uniform heat conduction from them. This not only ensures the tab belt remains horizontal and stable during transport, avoiding mounting errors caused by sagging or offset, but also effectively increases the material temperature and activity of the tab belt itself through continuous preheating. Subsequently, when the adsorption component 440 precisely applies the tape to the tab strip, the tab strip has been fully preheated, resulting in a high surface temperature that significantly enhances the initial adhesion and wettability of the tape. This ensures a stronger and more uniform bond between the tape and the tab strip, providing a reliable connection foundation for subsequent processes. After the tab strip is adhered, the pre-melting power component 522 operates by passing through the area composed of two pre-melting plates 521, clamping the tape and tab strip between them. The pre-melting plates 521 are heated to approximately 130°C, melting the surface material of the tape and firmly adhering it to the tab strip surface. During this process, continuous high-temperature pressure helps to effectively remove air bubbles that may exist between the two layers of tape and at the contact surface between the tape and the tab strip, ensuring a uniform and gapless bonding interface and improving the overall reliability and consistency of the adhesion. After preheating and melting the tabs and tape, they are conveyed to the working area consisting of two hot press plates 531. The hot press power component 532 is controlled to operate, causing the two hot press plates 531 to clamp the tape and tabs. The temperature of the hot press plates 531 is controlled at approximately 150°C, causing the surface material of the preheated tape to soften and even partially melt again under heat. This allows the tape to fully fill the tiny unevenness on the surface of the tabs under pressure, achieving a firm and uniform bond. This process divides the tape hot-melting process into two steps: first, pre-melting initially fixes and removes air bubbles between the adhesive layer and the tabs to avoid bonding defects; then, final hot pressing is completed under precise temperature and pressure control to ensure that the adhesive has a regular shape and tight edges. This step-by-step process not only improves overall work efficiency but also significantly enhances the reliability and appearance consistency of the bonding, effectively ensuring the sealing and insulation performance in subsequent battery module assembly. As the tab belt moves, the central processing unit controls the movement of the corresponding power components to disengage the tab belt from the upper tab preheating plate 511, pre-melting plate 521, and hot pressing plate 531, facilitating the forward movement of the tab belt.

[0056] refer to Figure 6The detection assembly 700 is disposed on the rear side of the hot pressing assembly 530, and includes a first deformable metal plate 710 (the same number as the tab unwinding rollers 210), a second deformable metal plate 720 (the same number as the tab unwinding rollers 210), a detection power component 730, an alarm 740, a detection upper frame 750, a metal plate mounting plate 760, and a detection lower frame 770. The detection lower frame 770 is mounted on the frame 100. The fixed ends of the detection upper frame 750, the alarm 740, and the detection power component 730 are mounted on the frame 100. A deformable metal plate 710 is mounted on the detection rack 750, a metal plate mounting plate 760 is mounted on the free end of the detection power component 730, a second deformable metal plate 720 is mounted on the metal plate mounting plate 760, the first deformable metal plate 710 and the second deformable metal plate 720 are respectively electrically connected to the alarm 740, the first deformable metal plate 710 and the second deformable metal plate 720 are respectively electrically connected to the input terminal of the central processing unit, and the output terminal of the central processing unit is electrically connected to the detection power component 730.

[0057] refer to Figure 6 After the tab tape and adhesive tape are hot-pressed together, they pass through the detection area between the first deformable metal plate 710 and the second deformable metal plate 720. The central processing unit controls the detection power component 730 to push its free end out, causing the second deformable metal plate 720 to abut against the area of ​​the tab tape without adhesive, and causing the tab tape to move slightly, so that the part that should be glued comes into contact with the first deformable metal plate 710. If there is a missing adhesive layer or no adhesion at the adhesive application point, the first deformable metal plate 710 will directly contact the tab tape substrate. At this time, a closed conductive circuit will be formed between the first deformable metal plate 710, the tab tape itself, and the second deformable metal plate 720, triggering the alarm 740 to start and emit an audible and visual alarm signal, promptly alerting the operator to the problem of poor adhesion. The central processing unit then controls the production line to stop working. This detection mechanism enables online, real-time, and non-destructive monitoring of adhesive layer integrity, which can promptly intercept defective products from flowing into the next process. It effectively avoids subsequent process defects caused by missing, misaligned, or improperly bonded tape, and significantly improves the consistency of the tabs and the overall reliability of the product.

[0058] refer to Figure 2The electrode moving assembly 600 includes a moving component 610, a first pressing component 620, and a second pressing component 630. The moving component 610, the first pressing component 620, and the second pressing component 630 are mounted on the frame 100.

The output terminal of the central processing unit is electrically connected to the fixed clamping power component 621.

[0061] refer to Figure 2 The second pressing component 630 has a similar structure to the first pressing component 620.

[0062] refer to Figure 2 and 7The tab tape passes through two movable clamping plates 611 and two fixed clamping power components 621. During the application of adhesive to the tab tape and the hot melting of the tape, the central processing unit controls the fixed clamping power component 621 to work, causing it to clamp the tab tape. The two movable clamping plates 611 move away from each other, and the tab tape contacts the lower movable clamping plate 611. After each processing of the tape by the pre-melting plate 521 and the hot pressing plate 531, the central processing unit controls the movable clamping power component 612 to move, causing the movable clamping plate 611 to clamp the tab tape. The central processing unit then controls the fixed clamping power component 621 to work, causing the upper fixed clamping power component 621 to move away from the tab tape. The central processing unit controls the movable power component 613 to work, driving the movable clamping power component 612 to move horizontally away from the tab feeding assembly 200, causing the movable clamping plate 611 to pull the tab tape, pulling it the same distance each time. The central processing unit controls the movement of the moving clamping power component 612, causing the moving clamping plate 611 to clamp the electrode tabs. It then controls the moving clamping power component 612 to move in the opposite direction, moving the moving clamping plate 611 away from the electrode tabs. Finally, it controls the moving power component 613 to work in the opposite direction, resetting the moving clamping plate 611, thus completing one full work cycle. This process is automatic, precise, and cyclical, effectively ensuring the stability and consistency of electrode tab application and conveying.

[0063] refer to Figure 7 The edge-cutting assembly 1100 is disposed between the moving component 610 and the second pressing component 630. The edge-cutting assembly 1100 includes an edge-cutting power component 1110, a third cutter 1120, an edge-cutting support plate 1130, two edge-cutting support rollers 1140, a first edge-cutting bracket 1150, a second edge-cutting bracket 1160, and an edge-cutting moving power component 1170. The first edge-cutting bracket 1150 is mounted on the frame 100. The edge-cutting support roller 1140 is bearing-connected to one top end of the first edge-cutting bracket 1150. Two edge-cutting brackets 1160 are mounted on the first edge-cutting bracket 1150. The fixed end of the edge-cutting moving power component 1170 is mounted on the second edge-cutting bracket 1160. The edge-cutting power component 1110 is mounted on the free end of the edge-cutting moving power component 1170 via a mounting vertical rod. The third cutter 1120 is mounted on the free end of the edge-cutting power component 1110. The edge-cutting support plate 1130 is mounted on the mounting vertical rod, located directly below the edge-cutting power component 1110 and lower than the uppermost side of the edge-cutting support roller 1140. The output end of the central processing unit is electrically connected to the edge-cutting power component 1110 and the edge-cutting moving power component 1170.

[0064] refer to Figure 7When the tab is stationary and the tape and the third cutter 1120 are at the same position in the width direction of the frame 100, the central processing unit controls the cutting edge moving power component 1170 to work, driving the cutting edge power component 1110, the third cutter 1120, and the cutting edge support plate 1130 to move, so that the tape enters the area formed by the third cutter 1120 and the cutting edge support plate 1130. Then, the cutting edge power component 1110 is controlled to work, so that the third cutter 1120 contacts the tape downwards, and cuts the tape under the support of the cutting edge support plate 1130.

[0065] refer to Figure 7 When the tape enters the hot-melt process, a small allowance needs to be reserved on one side near the cutting power unit 1110. This is to compensate for the natural shrinkage of the tape during preheating and subsequent hot pressing. By reserving this allowance, problems such as insufficient tape length or loose bonding due to heat shrinkage can be effectively avoided, thus ensuring bonding accuracy and adhesion strength in the final forming stage, improving overall processing quality and product consistency. Alternatively, the cutting power unit 1110, the third cutter 1120, and the cutting support plate 1130 can be installed on both sides of the tape. Simultaneously, since the tape will naturally sag during transport due to gravity, this process also removes the excess sagging by precision cutting, ensuring the tape remains flat and aligned before subsequent processes. This creates uniform and stable conditions for subsequent hot pressing, further ensuring that the final product's appearance and performance meet high standards.

[0066] refer to Figure 8 The slitting assembly 800 is located behind the first clamping component 620 and includes a second cutter 810, a cutter power component 820, a slitting moving power component 830, a light-shielding sensor 840, a slitting moving frame 850, a sensor bracket 860, a slitting frame 870, and two slitting fixing components 880.

[0069] refer to Figure 8 The tab tape passes through the area formed by the slitting moving plate 882 and the slitting fixing plate 883, as well as the slitting through slot 871. When the fixing clamping plate clamps the tab tape and the tape, the central processing unit controls the slitting clamping power component 881 to work, causing the slitting moving plate 882 to move downwards and clamp the tab tape with the slitting fixing plate 883. The central processing unit controls the slitting moving power component 830 to work, driving the cutting power component 820 and the second cutting blade 810 to move as a whole, accurately positioning them to the preset tape slitting position. The light-shielding sensor 840 can detect the passing tab tape and record its light-shielding time. Combining the real-time moving speed of the free end of the slitting moving power component 830, the actual measured width of the current tab tape is accurately calculated using the relationship between time and speed. Subsequently, the calculated width is compared and verified with the preset standard width of the tab tape to determine whether the tab tape has shifted position or angle during transmission, effectively realizing real-time monitoring and quality inspection of the tab tape alignment status, ensuring the accuracy and stability of the slitting process. The control cutter power unit 820 is activated, driving the second cutter 810 to perform a cutting action, efficiently cutting the tape between multiple connected tabs. This process enables the rapid separation of multiple tabs after synchronous adhesive application, ensuring not only neat and consistent cuts but also facilitating independent winding or further processing of subsequent products, thereby improving the continuity and automation level of the overall production process.

[0075] refer to Figure 9 and 10 The hot-melt component 910 operates at 240℃, melting the slit tape to soften it and give it good fluidity, allowing it to make close contact with the tab surface and fuse with the tab. The cold-press box 921 applies stable pressure at a low temperature, causing the tape to quickly solidify on the tab and form a preliminary shape, preventing displacement or deformation of the tape in subsequent processes. The tape-consolidating component 930 performs final treatment on the composite area under controlled temperature. The tab-consolidating heating plate 935 maintains a holding temperature of approximately 150℃, and the tape-consolidating heating plate 936 is set at approximately 140℃. Through differentiated temperature control, the tabs on both sides of the tape are heated at 150℃. The tabs are heated for a period before the tape is heated, ensuring the tabs are kept at a suitable temperature to prevent heat damage and further promoting the mutual penetration and fusion of tape molecules and the substrate. This significantly strengthens the tape's adhesion and interfacial bonding strength, ensuring a durable and reliable fusion effect. The bonding quality of the tape on the electrode tab surface was optimized. By controlling the temperature and pressure in stages, a strong and uniform adhesive structure was formed between the tape and the electrode tab.
