[0002] In the manufacturing process of rechargeable batteries, cell encapsulation is a crucial step. Tape bonding is used to attach tape to the battery terminals to achieve insulation, fixation, and sealing. In the rechargeable battery manufacturing industry, with continuous technological advancements and increasingly diversified market demands, the diversity of battery models is rapidly growing. The differences in the size, shape, and distribution of the terminals among different battery models place higher demands on the tape bonding process. The tape bonding process is not only related to battery safety but is also a key factor in ensuring battery lifespan. Therefore, the performance of the tape bonding mechanism directly affects the efficiency of battery manufacturing and the quality of the final product.

[0003] However, the feeding and positioning systems of existing adhesive applicator mechanisms are often designed based on fixed tape specifications to match fixed battery models. Therefore, when changing battery models, a lot of time is required to debug or even redesign the original equipment, which seriously affects the efficiency of cell packaging.

[0004] As can be seen from the above, the existing adhesive application mechanism has poor applicability, which affects the efficiency of cell packaging. Utility Model Content

The second driving component is driven to connect with the adapter plate. The second adsorption head is disposed on the bottom surface of the adapter plate, and the suction port of the second adsorption head is disposed facing the bottom side of the frame. Flattening rollers are rotatably disposed on the sides of the two second adsorption heads facing each other, and the flattening rollers extend along the width direction of the frame.

[0011] Furthermore, the flattening roller is disposed at one end of the suction port of the second suction head, and the suction port of the second suction head is coplanar with the bottom end of the flattening roller; and / or along the width direction of the frame, the extension length of the flattening roller is not less than the extension length of the suction port of the second suction head.

[0012] Furthermore, the lifting module includes a lifting drive component, a fixed frame, and an adjusting drive component. The lifting drive component is driven to the fixed frame, the adjusting drive component is mounted on the fixed frame, and the two adsorption components are slidably mounted on the fixed frame.

[0013] Furthermore, the transplanting assembly also includes a translation drive component mounted on the frame, and the lifting module is slidably mounted on the frame along the length of the frame, with the translation drive component and the lifting module being drivenly connected.

[0014] According to another aspect of the present invention, an adhesive applicator is provided, the adhesive applicator including a feeding mechanism and the aforementioned adhesive applicator, the feeding mechanism being disposed on one side of the adhesive applicator, the feeding mechanism including a mounting frame and at least one feeding roller rotatably disposed on the mounting frame, the feeding roller being used to place adhesive tape.

[0015] Furthermore, the feeding mechanism also includes a stretching drive, a clamping structure, a third drive, a cutter, and a sensor. The stretching drive is mounted on the mounting frame. The clamping structure includes a support plate, a clamping drive, a first clamping plate, and a second clamping plate.

[0016] The adhesive application mechanism of this utility model includes a frame, a transplanting component, and an adsorption component. The transplanting component is mounted on the frame and includes at least a lifting module. The adsorption component includes a first adsorption structure, a second adsorption structure, and a driving structure. The lifting module is driven to the first adsorption structure. The first adsorption structure adsorbs the portion of the adhesive tape corresponding to the top surface of the battery cell. The second adsorption structures are arranged in pairs on both sides of the first adsorption structure and adsorb the portion of the adhesive tape corresponding to the large surfaces on both sides of the battery cell. The driving structure includes a first driving component and a second driving component. The lifting module is driven to the first driving component, and the first driving component is driven to the second driving component. The first driving component is used to drive the second driving component to move along the height direction of the frame. The second driving component is driven to the two paired second adsorption structures, and the second driving component drives the two second adsorption structures to move closer to or further away from each other.

[0017] As can be seen from the above, the adsorption assembly of this application uses a first adsorption structure to adsorb the part of the tape corresponding to the top of the battery cell, and two second adsorption structures to adsorb the part of the tape corresponding to the large surface of the battery cell. The first and second adsorption structures work together to adsorb and position the tape. When the tape is bonded to the battery cell, the first and second adsorption structures perform their actions independently, thereby achieving the bonding of the tape to the top surface and the large surface of the two sides of the battery cell. The setting of the first and second adsorption structures in this application is beneficial to improving the bonding rate of the tape and the stability of the bonding action, thereby improving the bonding efficiency of the tape.

[0018] The second adsorption structure used in this application is disposed on both sides of the first adsorption structure. Under the driving action of the second driving member, the two second adsorption structures can move away from or towards each other. During the adhesive application process, by adjusting the distance between the two second adsorption structures, interference with the tape bonding action caused by the loose membrane at the top of the battery cell can be avoided. The relatively movable structure of the two second adsorption structures in this application ensures the tape bonding action and improves the tape bonding efficiency. At the same time, under the driving action of the second driving member, the two second adsorption structures can move away from or towards each other, thereby forming an adjustable accommodating space between the two second adsorption structures to adjust the length of the tape in contact with the top of the battery cell. This makes it applicable to battery cells of different sizes, which helps to improve the applicability of the structure and expand the application scenarios of the adhesive application mechanism.

[0019] The lifting module of this application is used to adjust the height of the first adsorption structure and the second adsorption structure, and the first driving component is used to further adjust the height of the second adsorption structure. The first driving component and the second driving component cooperate to adjust the position of the second adsorption structure so that the first adsorption structure and the second adsorption structure can move independently, thereby increasing the applicable range and improving the adhesive efficiency.

[0030] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0031] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0032] To address the problem that poor applicability of existing adhesive application mechanisms affects the efficiency of battery cell packaging, this application provides an adhesive application device for cutting and bonding adhesive tape 110 to the battery cell. The adhesive tape 110 has a portion that is bonded to the top surface of the battery cell and a portion that is bonded to the two large surfaces of the battery cell.

[0033] In this application, the tape 110 is provided with a liquid inlet 111 corresponding to the liquid injection hole on the top cover that matches the battery cell, so as to ensure the flow of electrolyte.

[0034] In this embodiment, the adhesive applicator includes a feeding mechanism and an adhesive applicator. The feeding mechanism is located on one side of the adhesive applicator and is used to place the adhesive tape 110 and cut it. The adhesive applicator then adsorbs and bonds the cut adhesive tape 110 to the battery cell. The adhesive applicator of this application, through the cooperation of the feeding mechanism and the adhesive applicator, can achieve rapid bonding of the adhesive tape 110. Furthermore, the adhesive applicator can avoid interference with the adhesive tape bonding caused by the looseness of the diaphragm on the top surface of the battery cell. Moreover, the bonding mechanism of this application is applicable to battery cells of different sizes, thereby improving the applicability of the adhesive applicator.

[0035] like Figures 1 to 6 As shown, the adhesive applicator includes a frame 10, a transfer assembly 20, and an adsorption assembly 30. The transfer assembly 20 is mounted on the frame 10, and the adsorption assembly 30 is mounted on the transfer assembly 20. The transfer assembly 20 is used to adjust the position of the adsorption assembly 30 as a whole, so as to move the adsorption assembly 30 toward one side of the feeding mechanism.

[0036] The transplanting assembly 20 includes a lifting module 210 and a translation drive 220. The translation drive 220 is mounted on the frame 10. The lifting module 210 is slidably mounted on the frame 10 along the length of the frame 10. The translation drive 220 is drivenly connected to the lifting module 210 to provide driving force for the lifting module 210 to slide along the length of the frame 10.

[0037] The translation drive component 220 can be a drive structure such as a motor or cylinder.

[0038] In this embodiment, the lifting module 210 is used to provide driving force for the adsorption assembly 30 to move along the height direction of the frame 10. Specifically, the adsorption assembly 30 of this application includes a first adsorption structure 310, a second adsorption structure 320 and a driving structure. The lifting module 210 is driven to connect with the first adsorption structure 310. The first adsorption structure 310 adsorbs the portion of the adhesive tape 110 corresponding to the top surface of the battery cell. The second adsorption structures 320 are arranged in pairs on both sides of the first adsorption structure 310. The second adsorption structures 320 adsorb the portion of the adhesive tape 110 corresponding to the large surfaces on both sides of the battery cell.

[0039] Specifically, along the length of the frame 10, two second adsorption structures 320 are symmetrically arranged on both sides of the first adsorption structure 310, and the two second adsorption structures 320 move toward or away from the side of the first adsorption structure 310.

[0040] The length direction of the frame 10 is Figure 1 and Figure 3 As shown in the X direction, the width direction of the frame 10 is... Figure 1 and Figure 3 As shown in the Y direction, the height direction of the frame 10 is... Figure 1 and Figure 3 The Z direction is shown.

[0041] In this embodiment, the driving structure includes a first driving member 330 and a second driving member 340. The lifting module 210 is driven to the first driving member 330 and the second driving member 340. The first driving member 330 is used to drive the second driving member 340 to move along the height direction of the frame 10. The second driving member 340 is driven to two pairs of second adsorption structures 320. The second driving member 340 drives the two second adsorption structures 320 to move closer to or further away from each other.

[0042] Specifically, the lifting module 210 is simultaneously driven and connected to the first adsorption structure 310 and the first driving member 330 to drive the first adsorption structure 310 and the first driving member 330 to adjust their positions along the height direction of the frame 10, so as to adapt the first adsorption structure 310 to adsorb the tape 110. At the same time, the first driving member 330 and the second driving member 340 cooperate, the first driving member 330 realizes the independent adjustment of the height of the two second adsorption structures 320, and the second driving member 340 further realizes the distance adjustment between the two second adsorption structures 320.

[0043] The adsorption assembly 30 of this application employs a first adsorption structure 310 to adsorb the portion of the tape 110 corresponding to the top of the battery cell, and two second adsorption structures 320 to adsorb the portion of the tape 110 corresponding to the large surface of the battery cell. The first adsorption structure 310 and the second adsorption structure 320 work together to achieve adsorption and positioning of the tape 110. When the tape 110 is bonded to the battery cell, the first adsorption structure 310 and the second adsorption structure 320 perform their actions independently, thereby achieving bonding of the tape 110 to the top surface and the large surfaces of the two sides of the battery cell. The arrangement of the first adsorption structure 310 and the second adsorption structure 320 in this application is beneficial to improving the bonding rate of the tape 110 and the stability of the bonding action, thereby improving the bonding efficiency of the tape 110.

[0044] The second adsorption structure 320 used in this application is disposed on both sides of the first adsorption structure 310. Under the driving action of the second driving member 340, the two second adsorption structures 320 can move away from each other or move closer to each other. During the adhesive application process, by adjusting the distance between the two second adsorption structures 320, interference with the adhesive tape bonding action caused by the loose membrane at the top of the battery cell can be avoided. The relative movable structure of the two second adsorption structures 320 in this application ensures the normal operation of the adhesive tape bonding action and improves the adhesive tape bonding efficiency.

[0045] Meanwhile, under the driving action of the second driving member 340, the two second adsorption structures 320 can move away from each other or move closer together, thereby forming an adjustable accommodating space between the two second adsorption structures 320 to adjust the length of the tape 110 in contact with the top of the battery cell, thus making it applicable to battery cells of different sizes, which helps to improve the applicability of the structure and expand the application scenarios of the adhesive applicator.

[0046] In this embodiment, the lifting module 210 is used to adjust the height of the first adsorption structure 310 and the second adsorption structure 320, and the first driving member 330 is used to further adjust the height of the second adsorption structure 320. The first driving member 330 and the second driving member 340 cooperate to adjust the position of the second adsorption structure 320 so that the first adsorption structure 310 and the second adsorption structure 320 can move independently, thereby increasing the applicable range and improving the adhesive efficiency.

[0047] In this embodiment, the second driving member 340 is used to drive the two second adsorption structures 320 to move along the length direction of the frame 10. According to the specific structural settings, this application provides the following two implementation methods.

[0048] In one specific embodiment, the second driving members 340 are arranged in pairs, and the second driving members 340 correspond one-to-one with the second adsorption structure 320 and are driven to connect. The two second driving members 340 drive the two second adsorption structures 320, and the driving ends of the two second driving members 340 are arranged in opposite directions along the length of the frame 10, thereby driving the two second adsorption structures 320 to move in position.

[0049] The second driving component 340 is a motor or cylinder, and the driving end of the second driving component 340 is a telescopic shaft. The telescopic shaft is fixedly connected to the second adsorption structure 320 so as to realize the telescopic movement of the telescopic shaft to drive the position movement of the second adsorption structure 320.

[0050] In another specific embodiment, a single second driving component 340 is provided. The second driving component 340 is a structural component such as a motor or cylinder. The driving end of the second driving component 340 is a rotating shaft. The driving structure also includes a screw and two movable blocks rotatably mounted on the screw. The driving end of the second driving component 340 is drivenly connected to the screw and drives the screw to rotate. The screw has external threads, and the two movable blocks have internal threads. The internal threads of the two movable blocks have opposite directions of rotation. The two movable blocks are drivenly connected to two second adsorption structures 320 respectively. By controlling the rotation direction of the screw, the two movable blocks can move synchronously closer or further away, thereby driving the second adsorption structures 320 to move closer or further away from each other.

[0051] like Figures 2 to 4As shown, the adsorption assembly 30 also includes a mounting plate 350, the lifting module 210 is driven to the mounting plate 350, the first driving component 330 and the first adsorption structure 310 are disposed on the mounting plate 350, and the first adsorption structure 310 is located below the first driving component 330 along the height direction of the frame 10.

[0052] The mounting plate 350 serves as a carrier for fixing the first driving component 330 and the first adsorption structure 310. The lifting module 210 drives the first driving component 330 and the first adsorption structure 310 to move along the height direction of the frame 10 through the mounting plate 350.

[0053] Specifically, the first adsorption structure 310 and the second adsorption structure 320 are both disposed on the lower side of the first driving member 330.

[0054] like Figure 4 As shown, the first adsorption structure 310 includes a connecting plate 311, a connector 315, a first adsorption head 313, and an elastic member 312. The connecting plate 311 is disposed on the mounting plate 350. The connecting plate 311 has a protrusion 314, which is disposed on one side of the top of the first adsorption head 313. Along the height direction of the frame 10, one end of the connector 315 abuts against the top surface of the protrusion 314, and the other end of the connector 315 passes through the protrusion 314 and is fixedly connected to the first adsorption head 313. The suction port of the first adsorption head 313 is disposed facing the bottom side of the frame 10. The elastic member 312 is disposed between the first adsorption head 313 and the protrusion 314.

[0055] The connector 315 is a sliding bolt with a screw head at one end and a thread at the other end. The connector 315 is fixedly connected to the first adsorption head 313 through the thread. The screw head is used to abut against the top surface of the protrusion 314, and the connector 315 and the protrusion 314 are in sliding fit.

[0056] Specifically, this application places the elastic element 312 between the first adsorption head 313 and the protrusion 314 to provide elastic force along the height direction of the frame 10. This allows the first adsorption structure 310 to adsorb the tape 110 during the adsorption process. The structure of the elastic element 312 facilitates the fine-tuning of the position of the first adsorption head 313, making it suitable for the first adsorption head 313 to fully adhere to the adsorption tape 110, which helps to improve the stability and efficiency of adsorption.

[0057] The elastic element 312 can be a spring structure. The elastic element 312 can be sleeved on the connector 315 or disposed on one side of the connector 315.

[0058] In this embodiment, the number of connectors 315 and elastic members 312 can be one or more, depending on actual needs.

[0059] In this embodiment, the first adsorption head 313 has a housing portion and an adsorption port disposed on the housing portion. The adsorption port of the first adsorption head 313 is disposed facing the bottom side of the frame 10 for adsorbing the tape 110 on the bottom side of the first adsorption head 313. The housing portion has an adsorption chamber inside, and a negative pressure can be formed inside the adsorption chamber by an external air pump, so that the adsorption port adsorbs the tape 110 by the negative pressure; correspondingly, the adsorption port of the first adsorption head 313 can also be blown outward by adjusting the air pump.

[0060] like Figure 2 and Figure 3 As shown, the second adsorption structure 320 includes a transfer plate 321, a second adsorption head 322, and a flattening roller 323. The second driving member 340 is driven to connect with the transfer plate 321. The second adsorption head 322 is disposed on the bottom surface of the transfer plate 321. The suction port of the second adsorption head 322 is disposed facing the bottom side of the frame 10. Flattening rollers 323 are rotatably disposed on the sides of the two second adsorption heads 322 facing each other. The flattening rollers 323 extend along the width direction of the frame 10.

[0061] The driving end of the second driving component 340 is fixedly connected to the adapter plate 321, and the second adsorption head 322 is fixed on the adapter plate 321. The two adapter plates 321 of the two second adsorption structures 320 move synchronously under the driving action of the two second driving components 340. The structural design of the adapter plate 321 facilitates the independent disassembly and replacement of the second adsorption head 322, which helps to improve the convenience of installation and thus improve the assembly efficiency.

[0062] In this embodiment, the second adsorption head 322 has a housing portion and a suction port disposed on the housing portion. The suction port of the second adsorption head 322 is disposed facing the bottom side of the frame 10 for adsorbing the tape 110 on the bottom side of the second adsorption head 322. The housing portion has an adsorption chamber inside, and a negative pressure can be formed inside the adsorption chamber by an external air pump, so that the suction port adsorbs the tape 110 by the negative pressure; correspondingly, the effect of blowing air out of the suction port of the second adsorption head 322 can also be achieved by adjusting the air pump.

[0063] In this embodiment, by providing a flattening roller 323 inside the second adsorption head 322, the flattening roller 323 facilitates the pressing of the tape 110. At the same time, during the bonding process of the tape 110, the tape 110 can be pressed onto the large surface of the battery cell by the rolling of the flattening roller 323, thereby improving the bonding efficiency of the tape 110 and helping to avoid wrinkles, bubbles and misalignment of the tape 110.

[0064] The flattening roller 323 is located at one end of the suction port of the second adsorption head 322. The suction port of the second adsorption head 322 and the bottom end of the flattening roller 323 are coplanar. This ensures that when the second adsorption structure 320 adsorbs the tape 110, the portion of the tape 110 located on the bottom side of the second adsorption structure 320 remains on a plane. This helps to improve the bonding efficiency of the tape 110 and avoids interference caused by bending of the tape 110.

[0065] Along the width direction of the frame 10, the extension length of the flattening roller 323 is not less than the extension length of the suction port of the second suction head 322, thereby ensuring that the flattening roller 323 can completely flatten the tape 110, and thus ensuring that the tape 110 is completely pressed onto the large surface of the battery cell by the flattening roller 323.

[0066] In this embodiment, the lifting module 210 includes a lifting drive 211, a fixed frame 212, and an adjustment drive. The lifting drive 211 is driven to the fixed frame 212, the adjustment drive is disposed on the fixed frame 212, two adsorption components 30 are slidably disposed on the fixed frame 212, the adjustment drive is driven to the adsorption components 30 and is used to adjust the distance between the two adsorption components 30, and the translation drive 220 is driven to the lifting drive 211, thereby driving the lifting module 210 to slide along the length direction of the frame 10 and be disposed on the frame 10.

[0067] Among them, the lifting drive component 211 is a structural component such as a motor or cylinder, and the lifting drive component 211 drives the fixed frame 212 to move up and down along the height direction of the frame 10.

[0068] Specifically, when it is necessary to set two tapes 110 on the battery cell, two adsorption components 30 are set accordingly, and the two adsorption components 30 adsorb the two tapes 110.

[0069] This application uses an adjustment drive on the fixing frame 212 to adjust the distance between the two adsorption components 30, thereby controlling the distance between the two tapes 110 to correspond to the distance between the positive and negative tabs of the battery cell, so as to achieve the bonding of the two tapes 110 to the same battery cell.

[0070] In this embodiment, the adjustment drive is a motor or a cylinder. The adjustment drive can be configured one-to-one with the adsorption components 30, in which case no additional structural components are required. The drive end of the adjustment drive is fixedly connected to the connecting plate 311. Alternatively, two adsorption components 30 can share one adjustment drive. For example, by using a screw and a movable block rotatably mounted on the screw, the internal threads of the two movable blocks are set to opposite directions. The movable block is fixedly connected to the mounting plate 350. By adjusting the drive, the screw is driven to rotate, thereby driving the two adsorption components 30 to move synchronously closer or further away.

[0071] like Figure 5 and Figure 6 As shown, the feeding mechanism includes a mounting frame 40 and at least one feeding roller 50 rotatably mounted on the mounting frame 40. The feeding roller 50 is used to place the adhesive tape 110, which is wound around the feeding roller 50. The adhesive tape 110 is used to adhere to the battery cell. A feeding motor 60 is also provided on the mounting frame 40, and the feeding motor 60 is driven and connected to the feeding roller 50 to release the adhesive tape 110.

[0072] The feeding mechanism further includes a stretching drive, a clamping structure 80, a third drive, and a cutter 90. The stretching drive is mounted on the mounting frame 40. The clamping structure 80 includes a support plate, a clamping drive, a first clamping plate, and a second clamping plate. The support plate is slidably mounted on the mounting frame 40 along the width direction of the frame 10. The stretching drive is driven to the support plate. The clamping drive is mounted on the support plate and driven to the first and second clamping plates. The clamping drive provides driving force to the ends of the tape 110 held by the first and second clamping plates. The third drive is mounted on the mounting frame 40 and located between the clamping structure 80 and the feeding roller 50. The third drive is driven to the cutter 90 and provides driving force for the cutter 90 to move toward or away from the tape 110 along the height direction of the frame 10.

[0073] Specifically, the clamping structure 80 is used to clamp the end of the tape 110 and pull the tape 110 under the drive of the stretching drive member. The feeding roller 50 rotates to feed the tape 110. After the tape 110 is pulled to a preset length, the third drive member can drive the cutter 90 to move to cut the tape 110 to form the tape 110 to be pasted. The adhesive applicator is used to adsorb the cut tape 110 and stick it to the battery cell.

[0074] Both the stretching drive and the third drive are driven by motors or cylinders.

[0075] In order to ensure the tension of the tape 110, multiple tension rollers 70 are also provided on the mounting frame 40. The tension rollers 70 are rotatably mounted on the mounting frame 40, and the tape 110 abuts against and adheres to the surface of the tension rollers 70.

[0076] In this embodiment, the first clamping plate is disposed on the top side of the tape 110, and the second clamping plate is disposed on the bottom side of the tape 110. Under the driving action of the clamping drive, the first clamping plate and the second clamping plate are controlled to move closer to each other and clamp the tape 110 or move away from each other and separate from the tape 110. The clamping drive is a motor or a cylinder, and the output end of the clamping drive is fixedly connected to the first clamping plate and the second clamping plate to drive their movement. When the tape 110 needs to be stretched, the first clamping plate and the second clamping plate clamp the tape 110 to achieve the stretching of the tape 110. After the tape 110 is cut, the first clamping plate and the second clamping plate are separated from the tape 110 under the drive of the clamping drive, and move towards the feeding roller 50 under the drive of the stretching drive to clamp the end of the tape 110 again.

[0077] In this embodiment, the feeding mechanism also includes a sensor 100, which is disposed on the mounting bracket 40. The sensor 100 is used to detect the position of the liquid passage hole 111 on the tape 110, thereby ensuring that the liquid passage hole 111 is located in the middle of the cut tape 110 portion, thereby ensuring the accuracy of the tape 110 cutting, and realizing the bonding of the tape 110 of the target preset length to the battery cell.

[0078] In this embodiment, the feeding mechanism can be one or two. When there are two feeding mechanisms, the mounting brackets 40 of the two feeding mechanisms are fixedly connected to form a whole, and the two feeding mechanisms are symmetrically arranged to provide two adhesive tapes 110 for the battery cell.

[0079] The implementation process of the adhesive applicator in this embodiment is as follows: The clamping structure 80 of the feeding mechanism clamps the end of the adhesive tape 110. The stretching drive drives the clamping structure 80 to move along the width direction of the frame 10 to stretch the adhesive tape 110. During this process, the feeding roller 50 rotates to feed the tape. Under the detection of the sensor 100, the stretching drive stops when it moves to a preset position. The third drive drives the cutter 90 to move and cut the adhesive tape 110. The transfer component 20 of the adhesive applicator moves the lifting module 210 and the adsorption component 30 to the adhesive tape 110 under the drive of the translation drive 220. The lifting drive 211 of the lifting module 210 drives the adsorption component 30 to descend and adsorb the adhesive tape 110. The first adsorption structure 310 adsorbs the adhesive tape 110 through the suction port under the drive of the lifting drive 211. In the liquid passage 111 section, the second driving member 340 drives two second adsorption structures 320 to adjust the spacing to adapt to the size of the battery cell. The second adsorption structures 320 adsorb onto the portions on both sides of the liquid passage 111 of the tape 110 to achieve adsorption of the tape 110. Then, under the action of the lifting module 210 and the translation driving member 220, the tape 110 is transferred to the upper side of the battery cell. The lifting driving member 211 lowers the first adsorption structure 310 to adhere the tape 110 to the top surface of the battery cell. Then, under the drive of the first driving member 330, the second adsorption structure 320 moves to the two large surfaces of the battery cell to achieve adhesion of the tape 110 to the two large surfaces of the battery cell. Under the drive of the first driving member 330, the second adsorption structure 320 moves downward so that under the action of the flattening roller 323, the tape 110 is completely adhered to the large surface of the battery cell.

[0080] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0081] The adsorption assembly 30 of this application employs a first adsorption structure 310 to adsorb the portion of the tape 110 corresponding to the top of the battery cell, and two second adsorption structures 320 to adsorb the portion of the tape 110 corresponding to the large surface of the battery cell. The first adsorption structure 310 and the second adsorption structure 320 cooperate to achieve adsorption and positioning of the tape 110. When the tape 110 is bonded to the battery cell, the first adsorption structure 310 and the second adsorption structure 320 perform their actions independently, thereby achieving the bonding of the tape 110 to the top surface and the large surface of the two sides of the battery cell. The arrangement of the first adsorption structure 310 and the second adsorption structure 320 in this application is beneficial to improving the bonding rate of the tape 110 and the stability of the bonding action, thereby improving the bonding efficiency of the tape 110.

[0082] The second adsorption structure 320 used in this application is disposed on both sides of the first adsorption structure 310. Under the driving action of the second driving member 340, the two second adsorption structures 320 can move away from each other or move closer together. During the adhesive application process, by adjusting the distance between the two second adsorption structures 320, interference with the adhesive tape bonding action caused by the loose membrane at the top of the battery cell can be avoided. The relatively movable structure of the two second adsorption structures 320 in this application ensures the normal operation of the adhesive tape bonding action and improves the adhesive tape bonding efficiency. At the same time, under the driving action of the second driving member 340, the two second adsorption structures 320 can move away from each other or move closer together, thereby forming an adjustable accommodating space between the two second adsorption structures 320 to adjust the length of the adhesive tape 110 in contact with the top of the battery cell. This makes it applicable to battery cells of different sizes, which helps to improve the applicability of the structure and expand the application scenarios of the adhesive application mechanism.

[0083] The lifting module 210 of this application is used to adjust the height of the first adsorption structure 310 and the second adsorption structure 320, and the first driving member 330 is used to further adjust the height of the second adsorption structure 320. The first driving member 330 and the second driving member 340 cooperate to adjust the position of the second adsorption structure 320 so that the first adsorption structure 310 and the second adsorption structure 320 can move independently, thereby increasing the applicability and improving the adhesive efficiency.
