[0025] Reference Figures 1 to 6 As shown, an embodiment of the present invention provides a method for double-sided adhesive bonding of a battery cell, comprising the following steps: Step S100: Control the first adhesive suction component 420 to flip along the first direction to the first adhesive dispensing position on one side of the tape; Step S200: Control the second adhesive suction component 610 to move to the second adhesive dispensing position. The first adhesive dispensing position and the second adhesive dispensing position are both located on the same side of the tape. In step S300, the cutting mechanism 300 is controlled to cut the tape to separate at least two film pieces from the tape, the first adhesive suction component 420 is controlled to pick up the film piece, and the second adhesive suction component 610 is controlled to pick up the other film piece. Step S400: Control the first adhesive suction component 420 to flip along the second direction to the first adhesive application position; Step S500: Control the second adhesive suction component 610 to move to the second adhesive application position. The first adhesive application position and the second adhesive application position are respectively located on both sides of the back of the battery cell. Step S600: Control the first adhesive suction component 420 to apply adhesive to the portion of the battery cell located at the first adhesive application position; In step S700, the second adhesive suction component 610 is controlled to apply adhesive to the portion of the battery cell located at the second adhesive application position.
[0026] Reference Figure 1 As shown, in steps S100 and S200, the double-sided adhesive application method of the battery cell can drive the first adhesive suction component 420 to flip along the first direction to the first adhesive-taking position, and control the second adhesive suction component 610 to move to the second adhesive-taking position.
[0027] Reference Figure 1 As shown, in step S300, the double-sided adhesive bonding method of the battery cell can control the cutting mechanism 300 to cut the adhesive tape, thereby separating at least two adhesive sheets from the tape. The first adhesive-taking position and the second adhesive-taking position are respectively set at the two cutting positions of the cutting mechanism 300, so that the first adhesive-absorbing component 420 and the second adhesive-absorbing component 610 can respectively pick up the two adhesive sheets.
[0028] Reference Figure 1 As shown, the first adhesive suction component 420 and the second adhesive suction component 610 can absorb the film by negative pressure adsorption, thereby keeping the film flat.
[0029] Reference Figure 1 As shown, in steps S400 and S500, the double-sided adhesive application method of the battery cell can control the first adhesive suction component 420 to flip along the second direction to the first adhesive application position, and control the second adhesive suction component 610 to move to the second adhesive application position. The first adhesive application position and the second adhesive application position are respectively located on both sides of the back of the battery cell, so that the first adhesive suction component 420 and the second adhesive suction component 610 are respectively moved to both sides of the back of the battery cell to apply adhesive to both sides of the back of the battery cell.
[0030] Reference Figure 1 As shown, during the flipping process of the first adhesive suction component 420, the film can be flipped, thereby changing the adhesive surface orientation of the film, so that the adhesive surface orientation of the film sucked by the first adhesive suction component 420 is opposite to that of the adhesive surface orientation sucked by the second adhesive suction component 610.
[0031] Reference Figure 1 As shown, in steps S600 and S700, the double-sided adhesive application method of the battery cell controls the first adhesive suction component 420 and the second adhesive suction component 610 to apply adhesive to the two end faces of the battery cell respectively. The double-sided adhesive application method of the battery cell can change the orientation of the adhesive surface of the suction film by flipping it after taking the adhesive, thereby quickly realizing the adhesive surface taking and double-sided adhesive application of the battery cell, which can improve the production efficiency of the battery cell.
[0032] Reference Figure 1 As shown in the related technologies, in the traditional double-sided adhesive application process for battery cells, the orientation of the adhesive side is fixed when the tape is transported in a plane. Therefore, the assembly line generally needs to add a flipping mechanism for the battery cells. By flipping the battery cells and coordinating with the operation of the adhesive application mechanism, the adhesive can be applied to both ends of the battery cells one by one, resulting in low production efficiency of the battery cells.
[0033] Reference Figure 1 As shown, the double-sided adhesive bonding method for battery cells provided in this embodiment of the invention can control the first adhesive suction component 420 to flip along a first direction and along a second direction, thereby controlling the first adhesive suction component 420 to flip between a first adhesive-taking position and a first adhesive-applying position. During the flipping process, the adhesive film can be flipped over, eliminating the need to flip the battery cell itself, allowing adhesive to be applied to both ends of the battery cell. This facilitates rapid adhesive taking and double-sided adhesive bonding of the battery cell, improving battery cell production efficiency. Specifically, the double-sided adhesive bonding method can control the first adhesive suction component 420 to flip 180° along the first direction from the first adhesive-applying position to the first adhesive-taking position. The method can also control the first adhesive suction component 420 to flip 180° along the second direction from the first adhesive-taking position to the first adhesive-applying position. The first and second directions are opposite; if the first direction is clockwise, the second direction is counterclockwise.
[0034] Reference Figure 1 As shown, specifically, the double-sided adhesive application method for the battery cell can simultaneously execute steps S100 and S200, and can simultaneously execute the adhesive taking of the first adhesive suction component 420 and the adhesive taking of the second adhesive suction component 610 in step S300. That is, while controlling the first adhesive suction component 420 to flip to the first adhesive taking position, the second adhesive suction component 610 is controlled to move to the second adhesive taking position, which can reduce the idle time of the first adhesive suction component 420 or the second adhesive suction component 610, thereby improving the adhesive taking efficiency.
[0035] Reference Figure 1 As shown, specifically, the double-sided adhesive application method for the battery cell can simultaneously execute steps S400 and S500, that is, while controlling the first adhesive suction component 420 to flip to the first adhesive application position, the second adhesive suction component 610 is controlled to move to the second adhesive application position, which can reduce the idle time of the first adhesive suction component 420 or the second adhesive suction component 610, thereby improving the production efficiency of the battery cell.
[0036] Reference Figure 1 As shown, specifically, the double-sided adhesive application method for the battery cell can simultaneously execute steps S600 and S700, that is, while controlling the first adhesive suction component 420 to apply adhesive to the battery cell, the second adhesive suction component 610 is also controlled to apply adhesive to the battery cell, which can reduce the idle time of the first adhesive suction component 420 or the second adhesive suction component 610, thereby improving the adhesive application efficiency of the battery cell.
[0037] It should be understood that in some other embodiments, the double-sided adhesive bonding method of the battery cell may execute steps S100 and S200 in a preset order, steps S400 and S500 in a preset order, and steps S600 and S700 in a preset order.
[0038] Reference Figure 2 As shown, it can be understood that the double-sided adhesive bonding method for this battery cell includes the following steps before the step of controlling the first adhesive suction component 420 to suction the adhesive film: Step S800: Control the first adhesive suction component 420 to switch to the adhesive taking state. The first adhesive suction component 420 includes a first adhesive suction block 422 and a second adhesive suction block 423 that can move relative to each other. The adhesive taking state is that the first adhesive suction block 422 and the second adhesive suction block 423 are set flush with each other. Reference Figure 2 As shown, in step S300, the double-sided adhesive bonding method for the battery cell involves controlling the first adhesive suction component 420 to pick up the adhesive film, including the following steps: In step S310, the first adhesive suction block 422 and the second adhesive suction block 423 are controlled to simultaneously suck air in order to jointly suck up the film.
[0039] Reference Figure 2 As shown, in step S800, before controlling the first adhesive suction component 420 to pick up the adhesive sheet, the double-sided adhesive application method of the battery cell can control the first adhesive suction component 420 to switch to the adhesive-taking state, so that the first adhesive suction block 422 and the second adhesive suction block 423, which can move relative to each other, are set up flush, so that when the first adhesive suction component 420 is in the first adhesive-taking position, the first adhesive suction block 422 and the second adhesive suction block 423 can be adjacent to the adhesive sheet, and the distance between the first adhesive suction block 422 and the second adhesive suction block 423 and the adhesive sheet is consistent.
[0040] Reference Figure 2 As shown, in step S310, the double-sided adhesive application method of the battery cell can control the first adhesive suction block 422 and the second adhesive suction block 423 to simultaneously suck air, that is, the first adhesive suction block 422 and the second adhesive suction block 423 jointly suck up the film.
[0041] Reference Figure 3 As shown, it can be understood that in step S600, the double-sided adhesive application method for the battery cell involves controlling the first adhesive suction component 420 to apply adhesive to the portion of the battery cell located at the first adhesive application position, including the following steps: Step S610: Control the first adhesive suction component 420 to switch to the adhesive application state. The first adhesive suction component 420 includes a first adhesive suction block 422 and a second adhesive suction block 423 that can move relative to each other. The adhesive application state is that the second adhesive suction block 423 and the first adhesive suction block 422 form a height difference. In step S620, the first adhesive suction block 422 and the second adhesive suction block 423 are controlled to move closer to the electrode and the main body of the battery cell, respectively, so that the adhesive film is simultaneously attached to the electrode and the main body.
[0042] Reference Figure 3As shown, in step S610, considering that the two sides of the battery cell are not completely symmetrical, there is a height difference between the main body and the tab on one side of the battery cell. Therefore, it is difficult to simultaneously apply adhesive to both the main body and the tab, or the adhesive film cannot be fully bonded to the battery cell, affecting the production quality of the battery cell. This double-sided adhesive application method for the battery cell can control the first adhesive suction component 420 to switch to the adhesive application state. The first adhesive suction component 420 includes a first adhesive suction block 422 and a second adhesive suction block 423 that can move relative to each other. The first adhesive suction component 420 can control the second adhesive suction block 423 to move obliquely relative to the first adhesive suction block 422, thereby creating a height difference between the second adhesive suction block 423 and the first adhesive suction block 422. The height difference between the second adhesive suction block 423 and the first adhesive suction block 422 matches the height difference between the main body and the tab of the battery cell.
[0043] Reference Figure 3 As shown, in step S620, at the first adhesive application position, the first adhesive-absorbing block 422 and the second adhesive-absorbing block 423 are respectively positioned opposite to the tab and the main body of the battery cell. This double-sided adhesive application method for the battery cell drives the first adhesive-absorbing block 422 and the second adhesive-absorbing block 423 to approach the tab and the main body of the battery cell, respectively. This allows the portion of the adhesive sheet corresponding to the first adhesive-absorbing block 422 to adhere to the tab of the battery cell, and the portion of the adhesive sheet corresponding to the second adhesive-absorbing block 423 to adhere to the main body of the battery cell. The height difference between the second adhesive-absorbing block 423 and the first adhesive-absorbing block 422 can be adapted to the height difference between the main body of the battery cell and the tab, thereby achieving simultaneous adhesive application to both the main body and the tab of the battery cell. Furthermore, the adhesive sheet can adapt to the shape changes between the main body and the tab of the battery cell, achieving complete adhesion between the adhesive sheet and the battery cell.
[0044] Reference Figure 4 As shown, it can be understood that the double-sided adhesive application method for the battery cell, after controlling the second adhesive suction component 610 to apply adhesive to the portion of the battery cell located at the second adhesive application position, also includes the following steps: Step S900: Obtain the film position information on the battery cell regarding the film. Step S1000: When the film position information is the preset position information, control the battery cell to move out of the first adhesive application position and the second adhesive application position.
[0045] Reference Figure 4 As shown, the double-sided adhesive application method for the battery cell includes a detection step. After the first adhesive suction component 420 and the second adhesive suction component 610 apply adhesive to the battery cell, the double-sided adhesive application method can obtain the adhesive film position information on the battery cell.
[0046] Reference Figure 4As shown, when the film position information is the preset position information, that is, the film has been attached to the cell, the double-sided adhesive method of the cell can control the cell to move out of the first adhesive position and the second adhesive position, so that the cell after adhesive application can continue to be transported, so that the cell to be adhesiveed can enter the first adhesive position and the second adhesive position.
[0047] Reference Figure 4 As shown, if the film position information is film missing information, that is, there is no film attached to the cell, the double-sided adhesive method of the cell can issue a prompt message to indicate the film missing, so that the cell can be removed in time or the adhesive can be reattached to the cell, which can improve the production quality and safety of the cell.
[0048] Reference Figure 5 As shown, it can be understood that the double-sided adhesive application method for the battery cell in step S700, which controls the second adhesive suction component 610 to apply adhesive to the portion of the battery cell located at the second adhesive application position, includes the following steps: Step S710: Control the second adhesive suction component 610 to move closer to the battery cell so that the adhesive sheet adheres to the battery cell; Step S720: Control the second adhesive suction component 610 to stop suctioning the film; Step S730: Control the second adhesive suction assembly 610 to move away from the battery cell and reset.
[0049] Reference Figure 5 As shown, the double-sided adhesive application method for the battery cell can first control the second adhesive suction component 610 to move closer to the battery cell so that the adhesive sheet can contact and adhere to the battery cell. Then, the double-sided adhesive application method can control the second adhesive suction component 610 to stop suctioning the adhesive sheet, that is, to eliminate the suction force applied to the adhesive sheet. Then, the second adhesive suction component 610 is driven away from the battery cell to reset, so as to separate the second adhesive suction component 610 from the adhesive sheet for the next adhesive application.
[0050] Reference Figure 6 As shown, it can be understood that in step S200, the double-sided adhesive bonding method for this battery cell involves controlling the cutting mechanism 300 to cut the adhesive tape, including the following steps: Step S210: Control the cutting mechanism 300 to generate a laser beam; Step S220: Control the laser beam to perform a circular cut on the tape.
[0051] In related technologies, when cutting adhesive tape rolls, the adhesive tape has a certain stickiness and may stick to the cutter or other metal surfaces, causing wrinkles on the surface of the adhesive tape and affecting the adhesive application effect.
[0052] Reference Figure 6As shown, the double-sided adhesive bonding method for the battery cell provided in this embodiment of the invention can use laser cutting instead of mechanical cutting. By separating the adhesive film from the tape through laser cutting, it is beneficial to avoid the problem of tape wrinkling caused by tape sticking to the cutter, and can effectively improve the cutting efficiency of tape.
[0053] Reference Figures 7 to 13 As shown, the adhesive applicator provided in some embodiments of the present invention can implement the double-sided adhesive application method for battery cells as described in any of the above embodiments. The adhesive applicator can implement the following... Figure 1 Steps S100 to S700 Figure 2 In steps S800 and S310, Figure 3 Steps S610 and S620 Figure 4 In steps S900 and S1000, Figure 5 Steps S710 to S730 Figure 6 Steps S210 to S220.
[0054] Specifically, the adhesive application device includes: a first conveying mechanism 100, a second conveying mechanism 200, a cutting mechanism 300, and a first adhesive application mechanism 400. The cutting mechanism 300 is specifically a laser cutting mechanism.
[0055] Reference Figure 7 , Figure 8 and Figure 9 As shown, the first conveying mechanism 100 is used to convey adhesive tape, and a first adhesive-taking position is provided on the conveying path of the first conveying mechanism 100. The second conveying mechanism 200 is used to convey battery cells, and a first adhesive-applying position is provided on the conveying path of the second conveying mechanism 200, so that multiple battery cells conveyed in an array can pass through the first adhesive-applying position sequentially. Specifically, the following explanation takes the example where the conveying direction of both the first conveying mechanism 100 and the second conveying mechanism 200 is from left to right.
[0056] Reference Figure 7 , Figure 8 and Figure 9 As shown, the cutting mechanism 300 is located on the conveying path of the first conveying mechanism 100. The cutting mechanism 300 can laser-cut the tape conveyed by the first conveying mechanism 100. Compared with the traditional mechanical cutting method, this adhesive applicator can use the laser beam generated by the cutting mechanism 300 to cut the tape, thereby separating the adhesive film from the tape. This avoids the problem of wrinkles caused by the tape sticking to the cutter, and ensures that the adhesive film separated from the tape remains flat, thus ensuring the quality of adhesive application to the battery cell.
[0057] Reference Figure 7 , Figure 8 and Figure 9As shown, the adhesive applicator also includes a first adhesive applicator 400, which is configured to move between a first adhesive dispensing position and a first adhesive applicator position. At the first adhesive dispensing position, the first adhesive applicator 400 can pick up the adhesive sheet using negative pressure suction. At the first adhesive applicator position, the first adhesive applicator 400 can apply the picked-up adhesive sheet to the battery cell.
[0058] Reference Figure 7 , Figure 8 and Figure 9 As shown, compared with the traditional glue-taking and glue-applying methods, this glue-applying device can separate the film by laser cutting, and by moving the first glue-applying mechanism 400 between the first glue-taking position and the first glue-applying position, it can quickly take the film and apply glue to the battery cell, thereby improving the production efficiency of the battery cell.
[0059] Reference Figure 7 , Figure 8 and Figure 9 As shown, it is understandable that in the related technologies, during the double-sided adhesive application process of the battery cell, the adhesive surface orientation is fixed when the tape is transported in a plane. Therefore, a flipping mechanism is required to flip the battery cell to achieve adhesive application on both ends of the battery cell. In other words, the related technologies cannot achieve simultaneous double-sided adhesive application of the battery cell. To address this, the first adhesive application mechanism 400 of the adhesive application device includes a first driving component, a flipping component 410, and a first adhesive suction component 420.
[0060] Reference Figure 7 , Figure 8 and Figure 9 As shown, the flipping component 410 is connected to the first adhesive suction component 420 to drive the first adhesive suction component 420 to flip between the first adhesive dispensing position and the first adhesive application position. Specifically, the flipping component 410 can drive the first adhesive suction component 420 to rotate about a left-right extending axis. The cutting mechanism 300 and the first adhesive dispensing position are located on the upper and lower sides of the adhesive tape, respectively, while the first adhesive application position is located on the upper side of the battery cell.
[0061] Reference Figure 7 , Figure 8 and Figure 9 As shown, when the flipping component 410 drives the first adhesive suction component 420 to flip backward and downward, the first adhesive suction component 420 can flip to the first adhesive-taking position, that is, flip to the underside of the tape. After the cutting mechanism 300 cuts the tape, the first adhesive suction component 420 can use negative pressure to suck up the film separated from the tape.
[0062] Reference Figure 7 , Figure 8 and Figure 9As shown, the flipping component 410 then drives the first adhesive suction component 420 to flip forward and upward, so that the first adhesive suction component 420 flips to the first adhesive application position, at which point the first adhesive suction component 420 is located above the battery cell. Then, the first driving component can drive the first adhesive suction component 420 to move closer to the battery cell, thereby adhering the suctioned adhesive to the surface of the battery cell. After the adhesive application is completed, the adhesive application device drives the first adhesive suction component 420 upward via the first driving component, in preparation for the next flipping of the first adhesive suction component 420.
[0063] Reference Figure 7 , Figure 8 and Figure 9 As shown, specifically, the flipping assembly 410 can drive the first adhesive suction assembly 420 to flip 180° along a first direction and along a second direction, so that the first adhesive suction assembly 420 flips between the first adhesive dispensing position and the first adhesive application position. Specifically, the flipping assembly 410 includes a first motor 411 and a flipping frame 412. The first motor 411 is drivenly connected to the flipping frame 412, and the first adhesive suction assembly 420 is connected to the flipping frame 412. The first motor 411 can drive the flipping frame 412 to flip along the first direction and along the second direction, thereby driving the first adhesive suction assembly 420 to flip between the first adhesive dispensing position and the first adhesive application position.
[0064] Reference Figure 7 , Figure 8 and Figure 9 As shown, the adhesive applicator, through the size and position coordination of the cutting mechanism 300, the flipping component 410, the first adhesive suction component 420, the first conveying mechanism 100 and the second conveying mechanism 200, can avoid the problem of the first adhesive suction component 420 colliding with the cutting mechanism 300, the tape and other devices when the first adhesive suction component 420 flips along the first direction and along the second direction.
[0065] Reference Figure 7 , Figure 8 and Figure 9 As shown, the adhesive applicator can flip the adhesive sheet that was originally facing upwards to the state of facing downwards by flipping the first adhesive suction component 420, so as to realize the adhesive application operation on the upper surface of the battery cell. This allows for the simultaneous application of adhesive to both ends of the battery cell without the need for an additional flipping mechanism, thus improving the efficiency of adhesive application to the battery cell.
[0066] Reference Figure 7 , Figure 8 and Figure 9As shown, it is understandable that, considering the non-perfect symmetry of the two sides of the battery cell, there is a height difference between the main body and the tab on one side of the battery cell. Therefore, it is difficult to simultaneously apply adhesive to both the main body and the tab, or the adhesive may not be able to fully adhere to the battery cell, affecting the production quality of the battery cell. To address this, the first adhesive suction component 420 of the adhesive application device includes a connecting frame 421, a first adhesive suction block 422, and a second adhesive suction block 423.
[0067] Reference Figure 7 , Figure 8 and Figure 9 As shown, the first adhesive suction block 422 is fixedly connected to the connecting frame 421, the second adhesive suction block 423 is movably connected to the connecting frame 421, and the first driving component is connected to the second adhesive suction block 423 to drive the second adhesive suction block 423 to move relative to the first adhesive suction block 422, so that the first adhesive suction component 420 switches between the adhesive-taking state and the adhesive-applying state. In the adhesive-taking state, the second adhesive suction block 423 and the first adhesive suction block 422 are flush, and in the adhesive-applying state, the second adhesive suction block 423 and the first adhesive suction block 422 form a height difference.
[0068] Reference Figure 7 , Figure 8 and Figure 9 As shown, specifically, when the flipping component 410 drives the first adhesive suction component 420 to flip to the first adhesive taking position, the first adhesive suction component 420 can switch to the adhesive taking state. In the adhesive taking state, the first adhesive suction block 422 and the second adhesive suction block 423 are flush, so that the first adhesive suction block 422 and the second adhesive suction block 423 are both adjacent to the film. The first adhesive suction block 422 and the second adhesive suction block 423 are provided with suction holes. Under the pressure change action of the external pump body, the first adhesive suction block 422 and the second adhesive suction block 423 can generate negative pressure, thereby realizing the suction of the separated film and maintaining the flatness of the film during the suction process.
[0069] Reference Figure 7 , Figure 8 and Figure 9 As shown, when the flipping component 410 drives the first adhesive suction component 420 to flip to the first adhesive application position, the first adhesive suction component 420 can switch to the adhesive application state. In the adhesive application state, the second adhesive suction block 423 and the first adhesive suction block 422 have a height difference, which causes the film to bend adaptively.
[0070] Reference Figure 7 , Figure 8 and Figure 9As shown, at the first adhesive application position, the first adhesive-absorbing block 422 and the second adhesive-absorbing block 423 are respectively positioned opposite to the electrode and the main body of the battery cell. Under the driving action of the first driving component, the portion of the adhesive sheet corresponding to the first adhesive-absorbing block 422 can be adhered to the electrode of the battery cell, and the portion of the adhesive sheet corresponding to the second adhesive-absorbing block 423 can be adhered to the main body of the battery cell. The height difference between the second adhesive-absorbing block 423 and the first adhesive-absorbing block 422 can be adapted to the height difference between the main body of the battery cell and the electrode, so as to achieve simultaneous adhesive application to the main body and the electrode of the battery cell, and to allow the adhesive sheet to adapt to the shape changes between the main body and the electrode of the battery cell, so as to achieve full adhesion between the adhesive sheet and the battery cell.
[0071] Reference Figure 7 , Figure 8 and Figure 9 As shown, it can be understood that the first drive assembly includes a first linear drive member 440, which includes a first end 441 and a second end 442 that are telescopic relative to each other. The first end 441 is fixedly connected to the connecting frame 421, and the second end 442 is connected to the second adhesive suction block 423 to drive the second adhesive suction block 423 to move obliquely relative to the first adhesive suction block 422.
[0072] Reference Figure 7 , Figure 8 and Figure 9 As shown, the adhesive applicator also includes a frame 500, and a roller 450 is rotatably connected to the side of the second end 442 facing away from the first end 441. When the flipping component 410 drives the first adhesive suction component 420 to flip to the first adhesive dispensing position, the roller 450 is configured to abut against the frame 500 so that the first end 441 and the second end 442 are close together, and the first adhesive suction component 420 switches to the adhesive dispensing state.
[0073] Reference Figure 7 , Figure 8 and Figure 9 As shown, specifically, during the process of the flipping component 410 driving the first adhesive suction component 420 to flip towards the first adhesive taking position, the roller 450 is configured to abut against the frame 500 so that the first end 441 and the second end 442 are close together, thereby switching the first adhesive suction component 420 to the adhesive taking state so as to achieve the suction of the film.
[0074] Reference Figure 7 , Figure 8 and Figure 9As shown, specifically, the first linear drive component 440 is a cylinder. During the flipping process where the flipping component 410 drives the first adhesive suction component 420 to flip towards the first adhesive application position, the roller 450 gradually separates from the frame 500, meaning the pressure exerted by the frame 500 on the roller 450 gradually dissipates. Under the pressure of the first linear drive component 440 itself, the first end 441 and the second end 442 can be reset. At this time, the first end 441 and the second end 442 are relatively far apart, thereby driving the second adhesive suction block 423 to move obliquely relative to the first adhesive suction block 422. Furthermore, the second adhesive suction block 423 and the first adhesive suction block 422 form a height difference, causing the adhesive sheet sucked by the first adhesive suction component 420 to form a Z-shape, facilitating simultaneous adhesive application to both the main body of the battery cell and the electrode tabs, which helps improve the bonding and matching degree between the adhesive sheet and the battery cell.
[0075] Reference Figure 7 , Figure 8 and Figure 9 As shown, the second adhesive suction block 423 can move obliquely relative to the first adhesive suction block 422, which can avoid the problem of excessive stretching or deformation of the film during bending.
[0076] Reference Figure 7 , Figure 8 and Figure 9 As shown, specifically, the frame 500 is provided with a slide groove 4211, and the second adhesive suction block 423 is slidably connected to the slide groove 4211, allowing the second adhesive suction block 423 to move obliquely relative to the first adhesive suction block 422. This adhesive applicator can improve the stability and straightness of the movement of the second adhesive suction block 423 by mutually limiting the movement of the second adhesive suction block 423, thereby improving the accuracy of adhesive application to the battery cell.
[0077] Reference Figure 7 , Figure 8 and Figure 9 As shown, it can be understood that the first driving assembly also includes a second linear driving member 430, which can be connected to the first adhesive suction assembly 420 at the first adhesive application position to drive the first adhesive suction block 422 and the second adhesive suction block 423 to move towards or away from the battery cell simultaneously.
[0078] Reference Figure 7 , Figure 8 and Figure 9As shown, specifically, the second linear drive component 430 includes a second motor 432 and a swing block 431. The second motor 432 is connected to the frame 500, one end of the swing block 431 is connected to the output shaft of the second motor 432, and the other end of the swing block 431 is rotatably connected to a pulley. The tilting frame 412 and the first adhesive suction assembly 420 are slidably connected via a guide rail to guide the lifting and lowering of the first adhesive suction assembly 420. A compression elastic element is provided between the first adhesive suction assembly 420 and the frame 500, which is used to drive the first adhesive suction assembly 420 to move upward along the guide rail.
[0079] Reference Figure 7 , Figure 8 and Figure 9 As shown, at the first adhesive application position, when the second motor 432 drives the swing block 431 to rotate, the pulley at the end of the swing block 431 can abut against the first adhesive suction assembly 420, thereby driving the first adhesive suction assembly 420 to move downward along the guide rail, thus adhering the suctioned adhesive sheet to the battery cell. When the pressure of the pulley on the first adhesive suction assembly 420 decreases or is eliminated, the first adhesive suction assembly 420 can move upward and reset under the action of the compression elastic element.

The first adhesive application mechanism 400 and the second adhesive application mechanism 600 are respectively used to apply adhesive to both sides of the back side of the battery cell. Specifically, the first adhesive application mechanism 400 and the second adhesive application mechanism 600 are respectively used to apply adhesive to the upper surface and the lower surface of the battery cell.

The second conveying mechanism 200 also includes a second adhesive dispensing position, which is located on the same side of the tape as the first adhesive dispensing position. Specifically, both the second adhesive dispensing position and the first adhesive dispensing position are located on the lower side of the tape.
[0082] Reference Figure 7 , Figure 10 and Figure 11As shown, the second adhesive applicator 600 includes a second drive assembly 620 and a second adhesive suction assembly 610. The second drive assembly 620 is connected to the second adhesive suction assembly 610 to drive the second adhesive suction assembly 610 to move between a second adhesive dispensing position and a second adhesive applicator position. At the second adhesive dispensing position, the second adhesive suction assembly 610 is at least configured to pick up adhesive film. At the second adhesive applicator position, the second drive assembly 620 can drive the second adhesive suction assembly 610 to move closer to or away from the battery cell.
[0083] Reference Figure 7 , Figure 10 and Figure 11 As shown, the adhesive applicator operates simultaneously with the first adhesive applicator 400 and the second adhesive applicator 600, which can pick up adhesive sheets from the same tape and simultaneously apply adhesive to the upper and lower surfaces of the battery cell. There is no need to set up a flipping mechanism for the battery cell, which can effectively improve the adhesive applicator efficiency for double-sided application of the battery cell.
[0084] Reference Figure 7 , Figure 11 and Figure 12 As shown, it can be understood that the second drive assembly 620 includes a third linear drive member and a fourth linear drive member.

The fourth linear drive member is connected to the second adhesive suction assembly 610 to drive the second adhesive suction assembly 610 to move linearly back and forth toward the battery cell.
[0085] Reference Figure 7 , Figure 11 and Figure 12 As shown, specifically, the third linear drive component can be a pneumatic push rod, a hydraulic push rod, or an electric push rod, etc., a linear drive mechanism. The third linear drive component can drive the second adhesive suction assembly 610 to move in the front-back direction, thereby driving the second adhesive suction assembly 610 to move between the second adhesive taking position and the second adhesive applying position.
[0086] Reference Figure 7 , Figure 11 and Figure 12 As shown, specifically, the fourth linear drive component includes a third motor 621, a drive arm 622, and a connecting rod 623. The output end of the third motor 621 is connected to one end of the drive arm 622, and the other end of the drive arm 622 is connected to one end of the connecting rod 623. The other end of the connecting rod 623 is connected to the second adhesive suction assembly 610. The second adhesive suction assembly 610 can be restricted from rotating by cooperating with the slide rail to form a crank-slider mechanism, thereby driving the second adhesive suction assembly 610 to move linearly closer to or away from the tape or battery cell to achieve the adhesive application action.
[0087] It should be noted that the second adhesive suction assembly 610 includes an adhesive suction block with suction holes. The adhesive suction block is connected to an external pump body. Under the pressure change action of the pump body, the end of the second adhesive suction assembly 610 generates negative pressure to achieve the suction of the film.
[0088] Reference Figure 7 , Figure 11 and Figure 12 As shown, it is understood that the adhesive applicator also includes a pick-up frame 700 that abuts against the adhesive tape. The pick-up frame 700 has a pick-up port. The cutting mechanism 300 is configured to laser cut the adhesive tape in the pick-up port. The first adhesive applicator 400 is capable of picking up the adhesive sheet in the pick-up port.

The base 221 can achieve magnetic levitation sliding with the magnetic levitation track 210. The clamping block 222 and the base 221 can be connected by threads to jointly clamp the battery cell and expose the battery cell's tabs and part of the main body to the outside.
[0093] Reference Figure 7 , Figure 12 and Figure 13As shown, the adhesive applicator can quickly move the battery cell to or from the first adhesive applicator position by sliding the pressure block and the magnetic levitation track 210 through magnetic levitation, thereby improving the production efficiency of the battery cell.
[0094] Reference Figure 7 , Figure 12 and Figure 13 As shown, it is understood that the adhesive application device also includes a detection component 230, which is configured to detect the film position information on the battery cell regarding the film.

The light source 232 illuminates the battery cell, and the camera 231 acquires information about the film position on the battery cell. When the film position information matches a preset position, meaning the film is properly bonded to the battery cell, the battery cell can be moved out of the first bonding position. In other words, this bonding device can detect the bonding status of the film on the battery cell through the detection component 230, facilitating the removal of defective products and improving the production quality and safety of the battery cells.
[0096] Reference Figure 7 , Figure 12 and Figure 13 As shown, when the film position information is film missing information, that is, no film is detected on the cell, a prompt message is issued to indicate the film missing, so that the cell can be removed in time or the film can be reapplied to the cell, thereby improving the production quality and safety of the cell.
[0097] It should be noted that the detection principle of the detection component 230 is a conventional technical method in this field, and will not be elaborated here.
