[0006] Furthermore, the top of the first clamping member is provided with an abutment piece extending toward the battery cell. When the two opposing first clamping members clamp the battery cell, the abutment piece blocks the top of the battery cell.

[0007] Furthermore, the bottom of the tilting table is provided with a first lifting mechanism, and the first driving part is connected to the lifting end of the first lifting mechanism; the first lifting mechanism can drive the first driving part and the first clamping member to move along the height direction to adjust the distance between the abutment piece and the tilting table.

[0013] (5) By setting the positioning component, the displacement of the battery cell in the width direction on the second tooling is avoided, ensuring the accuracy of the battery cell position. At the same time, the cooperation between the second clamping component and the second driving part allows the second clamping component to simultaneously abut against two battery cells in the battery cell group, so as to ensure that the two battery cells are aligned in the length direction, avoid displacement deviation between the two battery cells, thereby improving the integrity of the battery cell group and facilitating the subsequent processing of the battery cell group.

[0014] This application also proposes a battery cell production line to achieve automatic matching, bonding, and adhesive application of battery cells.

[0015] To achieve the above objectives, the technical solution of this application is implemented as follows: A battery cell production line includes a transfer device, which has a feeding station, a cell assembly station, an adhesive application station and a unloading station arranged in sequence; the cell assembly station is provided with a cell assembly device as described above, and the adhesive application station is provided with an adhesive application device.

[0020] Compared with related technologies, this application has the following advantages: (1) The battery cell production line described in this application, through the combination of transfer device, battery cell assembly device and adhesive application device, can realize the automated production process of battery cell feeding, assembly, adhesive application and unloading, which is conducive to improving the continuity and efficiency of battery cell production. The battery cell assembly device and adhesive application device can ensure the effect of battery cell assembly and battery cell assembly adhesive application, which is conducive to improving the overall quality stability of battery cell production and meeting the needs of large-scale production.

[0021] (2) Through the coordinated arrangement of the third tooling and the adhesive application section, the third tooling can stably support the battery cell assembly to be adhesive applied, and the first translation mechanism and the second lifting mechanism in the adhesive application section can effectively drive the adhesive application mechanism to move, thereby achieving precise adhesive application to different parts of the battery cell assembly.

[0022] (3) By setting up a tape reel, a dispensing roller group and a pasting plate on the mounting frame, the tape on the tape reel can be conveyed to the pasting plate through the dispensing roller group.

While ensuring the quality of pasting, it can be adapted to battery cell groups of different sizes and has good versatility.

[0023] (4) By setting up the second translation mechanism and the fixed and movable adhesive application mechanism, it is possible to apply adhesive to different positions of the battery cell group at the same time, and the movable adhesive application mechanism can move along the length direction of the battery cell group through the second translation mechanism to change the spacing of each adhesive application mechanism, adapt to battery cell groups of different lengths, and adjust the adhesive application position on the battery cell group to meet the application requirements of adhesive application points with different spacing on the battery cell group.

[0024] (5) By using the guide rail and guide rod in combination, the dual guiding effect of the guide rail and guide rod can ensure that the movable adhesive applicator slides smoothly along the length of the battery cell when adjusting its position. The locking part quickly fixes its position to prevent position displacement caused by vibration and other factors during the adhesive application process, ensuring the stability of the spacing between each adhesive applicator during adhesive application, thereby improving the quality consistency of adhesive application at multiple positions at the same time.

[0031] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0032] An embodiment of the first aspect of this application provides a battery cell bonding device.

[0033] In related technologies, the five-cell assembly process mainly relies on manual labor or semi-automated equipment. The efficiency of the five-cell assembly process is low, making it difficult to meet the needs of large-scale automated production.

[0034] In view of this, in order to overcome the shortcomings of related technologies, the battery cell bonding device in this embodiment combines... Figure 1As shown, the overall design includes a base 101, a first tooling 102, a second tooling 103 and a drive unit disposed on the base 101.

[0035] The first fixture 102 has a fixing part for fixing the battery cell 5, and the second fixture 103 has a bearing surface for placing the battery cell 5. The driving part can drive the first fixture 102 to flip onto the second fixture 103, so that the battery cell 5 fixed on the first fixture 102 is stacked on the battery cell 5 mounted on the second fixture 103 to form a battery cell group 6.

[0036] Therefore, through the cooperative arrangement of the first tooling 102 and the second tooling 103, the fixing part can stably mount the battery cell 5 on the first tooling 102. During the process of the first tooling 102 being driven to flip towards the second tooling 103, the battery cell 5 mounted on the first tooling 102 can be flipped and stacked on the battery cell 5 of the second tooling 103, so as to realize the pairing and core bonding of the battery cell 5, and has high working efficiency, which is conducive to the automated production of the battery cell 5.

[0037] Based on the above overview, specifically, let's continue to combine... Figures 1 to 3 As shown, in some exemplary embodiments, the first tooling 102 includes a rotating shaft 1021 rotatably mounted on a base 101, and a tilting table 1022 connected to the rotating shaft 1021 and used to mount the battery cell 5. The driving unit includes a drive motor 1011 for driving the rotating shaft 1021 to rotate. The fixing unit includes a first driving unit 1023 and a first clamping member 1024 connected to the driving end of the first driving unit 1023. The first clamping members 1024 are disposed on opposite sides in the width direction of the battery cell 5, and the first driving unit 1023 can drive the two opposing first clamping members 1024 to move closer or further apart to clamp and fix the battery cell 5.

[0038] With the arrangement of the rotating shaft 1021 and the flipping table 1022, the flipping table 1022 can ensure the stability of the flipping process by means of the smooth rotation of the rotating shaft 1021. Furthermore, the rotation of the rotating shaft 1021 by the drive motor 1011 facilitates the control of the flipping angle and speed of the first tooling 102. At the same time, with the arrangement of the first clamping member 1024 and the first driving part 1023, the first clamping member 1024 can clamp and fix the battery cell 5, ensuring the stability of the battery cell 5 on the first tooling 102, and can adjust the clamping spacing to adapt to battery cells 5 of different widths, thereby improving versatility.

[0039] In a specific implementation, the drive motor 1011 of this embodiment is located below the first tooling 102 and the second tooling 103, and is connected to the rotating shaft 1021 via a transmission mechanism to drive the rotating shaft 1021 to rotate. The transmission mechanism can be a conventional belt or synchronous belt transmission mechanism, as long as it can ensure the power transmission between the drive motor 1011 and the rotating shaft 1021.

[0040] Furthermore, the first drive unit 1023 in this embodiment can adopt conventional drive mechanisms such as cylinders and linear modules that are well known to those skilled in the art. Its drive end can be connected to the first clamping member 1024 and move along the width direction of the battery cell 5. This will not be elaborated further here.

[0041] In addition, the first tooling 102 of this embodiment may be provided with a plurality of first driving parts 1023 arranged along the width direction of the battery cell 5. Each first driving part 1023 is connected to two oppositely arranged first clamping members 1024 to increase the number of clamping points for the battery cell 5 and improve the fixing effect of the battery cell 5.

[0042] In some exemplary embodiments, the top end of the first clamping member 1024 is provided with an abutment piece 1025 extending toward the battery cell 5. When the two opposing first clamping members 1024 clamp the battery cell 5, the abutment piece 1025 blocks the top of the battery cell 5. By setting the abutment piece 1025, the abutment piece 1025 can block the top of the battery cell 5 when clamping the battery cell 5. During the flipping process of the first fixture 102, the abutment piece 1025 can block the battery cell 5, prevent the battery cell 5 from falling off the flipping table 1022 during the flipping process, and ensure that the battery cell 5 is stacked on the battery cell 5 of the second fixture 103 in a preset posture, avoiding displacement of the battery cell 5 and affecting the core bonding effect of the battery cell 5.

[0043] Furthermore, in some exemplary embodiments, the bottom of the tilting table 1022 is provided with a first lifting mechanism 1026, and a first drive unit 1023 is connected to the lifting end of the first lifting mechanism 1026. The first lifting mechanism 1026 can drive the first drive unit 1023 and the first clamping member 1024 to move in the height direction to adjust the distance between the abutment piece 1025 and the tilting table 1022.

[0044] By setting the first lifting part, the first lifting part can drive the first driving part 1023 and the first clamping member 1024 to move in the height direction, thereby adjusting the distance between the abutment piece 1025 and the flipping table 1022 to adapt to the battery cells 5 of different thicknesses, ensuring that the abutment piece 1025 can fit with the top of the battery cell 5, improving versatility, further improving the fixing effect of the battery cell 5 on the flipping table 1022, and ensuring the stability of the battery cell 5 during the flipping process of the first tooling 102.

[0045] In a specific implementation, the first lifting mechanism 1026 of this embodiment can be a cylinder, and the piston rod of the cylinder is fixedly connected to the tilting table 1022, and the cylinder barrel is connected to a lifting plate 1027. When the cylinder extends or retracts, the cylinder barrel can drive the lifting plate 1027 to move up and down. At this time, the lifting plate 1027 serves as the lifting end of the first lifting mechanism 1026, and the first driving part 1023 is installed on the lifting plate 1027.

[0046] Specifically, in order to maintain the stability of the lifting plate 1027 during lifting, guide posts are provided at the four corners of the bottom of the tilting table 1022 in this embodiment. The guide posts can be inserted into the lifting plate 1027 to guide the lifting plate 1027 to move smoothly in the height direction.

[0047] In some exemplary embodiments, the second tooling 103 is provided with a positioning member 1031, which constrains the position of the battery cell 5 in the width direction. The second tooling 103 may also be provided with a second driving part 1032 and a second clamping member 1033, which are respectively disposed at both ends in the length direction of the battery cell 5. The second driving part 1032 can drive the two second clamping members 1033 to move away from or towards each other, and the second clamping members 1033 can simultaneously abut against the end faces of two battery cells 5 on the same side in the battery cell assembly 6.

[0048] The positioning element 1031 prevents the battery cell 5 from shifting in the width direction on the second tooling 103, ensuring the accuracy of the battery cell 5's position. Simultaneously, the cooperation between the second clamping element 1033 and the second driving part 1032 allows the second clamping element 1033 to simultaneously abut against two battery cells 5 in the battery cell assembly 6, ensuring that the two battery cells 5 are aligned in the length direction, preventing displacement deviation between the two battery cells 5, thereby improving the overall integrity of the battery cell assembly 6 and facilitating subsequent processing of the battery cell assembly 6.

[0049] In specific implementation, the positioning members 1031 of this embodiment are respectively disposed on opposite sides in the width direction of the battery cell 5, and at least two positioning members 1031 are provided on each side of the battery cell 5 to prevent misalignment of the two ends in the length direction of the battery cell 5. At the same time, the second driving part 1032 of this embodiment can adopt conventional driving mechanisms such as cylinders and linear modules well known to those skilled in the art. Its driving end can be connected to the second clamping member 1033 to move along the length direction of the battery cell 5, which will not be described in detail here.

[0050] It is worth noting that, regarding the cell-combining device of this embodiment, based on the above exemplary implementations, in specific implementation, as a preferred embodiment, it is still composed of... Figures 1 to 3 As shown.

[0051] The battery cell assembly device of this embodiment includes a base 101, and a first tooling 102, a second tooling 103 and a drive motor 1011 disposed on the base 101.

[0052] The first tooling 102 includes a rotating shaft 1021 rotatably mounted on a base 101 and driven by the output shaft of a drive motor 1011, and a tilting table 1022 connected to the rotating shaft 1021. The bottom of the tilting table 1022 is connected to the piston rod of a cylinder, and a lifting plate 1027 is connected to the cylinder barrel. Guide posts are also provided at the four corners of the bottom of the tilting table 1022, and these guide posts can pass through the lifting plate 1027. The lifting plate 1027 has two first driving parts 1023, and each first driving part 1023 is connected to two opposing first clamping members 1024. The top of each first clamping member 1024 has an abutment piece 1025 extending towards the side where the battery cell 5 is located.

[0053] In addition, the second tooling 103 is provided with positioning members 1031, which are respectively located on opposite sides of the width direction of the battery cell 5, and at least two positioning members 1031 are provided on each side of the battery cell 5. The second tooling 103 is provided with a second driving part 1032 and a second clamping member 1033, which are respectively located at both ends of the length direction of the battery cell 5, and the second driving part 1032 can drive the two second clamping members 1033 to move away from or towards each other, and the second clamping members 1033 can simultaneously abut against the end face of the same side of two battery cells 5 in the battery cell group 6.

[0054] The battery cell bonding device of this embodiment adopts the above design. Through the cooperation of the first tooling 102 and the second tooling 103, the fixing part can stably mount the battery cell 5 on the first tooling 102. During the process of the first tooling 102 being driven to flip towards the second tooling 103, the battery cell 5 mounted on the first tooling 102 can be flipped and stacked on the battery cell 5 of the second tooling 103 to realize the pairing and bonding of the battery cell 5. It has high working efficiency, is conducive to the automated production of the battery cell 5, and has good practicality.

[0055] The second aspect of this application provides a battery cell production line, which, in its overall design, continues to incorporate... Figure 4 , Figure 5 As shown, it includes a transfer device 2, and the transfer device 2 has a loading station 2a, a core-assembly station 2b, an adhesive-applying station 2c, and a unloading station 2d arranged in sequence.

[0056] The battery cell assembly station 2b is equipped with the battery cell assembly device 1 as described above, and the adhesive application station 2c is equipped with the adhesive application device 3. The transfer device 2 can transport the battery cell 5 at the loading station 2a to the battery cell assembly device 1, and the transfer device 2 can transfer the battery cell group 6 in the battery cell assembly device 1 to the adhesive application device 3 for adhesive application, and can transport the adhesive-applied battery cell group 6 to the unloading station 2d.

[0057] Therefore, by combining the transfer device 2, the cell assembly device 1, and the adhesive application device 3, an automated production process for feeding, assembling, applying adhesive, and unloading of the cell 5 can be achieved. This is beneficial to improving the continuity and efficiency of cell 5 production. The cell assembly device 1 and the adhesive application device 3 can ensure the effectiveness of cell 5 assembly and cell assembly 6 adhesive application, which is beneficial to improving the overall quality stability of cell 5 production and meeting the needs of large-scale production.

[0058] Based on the above general introduction, specifically, the transfer equipment in this embodiment includes a frame 201 and a plurality of robotic arms 202 movably mounted on the frame 201. The loading station 2a, the core-assembly station 2b, the adhesive-applying station 2c, and the unloading station 2d are arranged sequentially below the frame 201 along the extending direction of the frame 201.

[0059] Multiple robotic arms 202 are positioned between two adjacent workstations. The robotic arms 202 between the loading workstation 2a and the core assembly workstation 2b, between the core assembly workstation 2b and the adhesive application workstation 2c, and between the adhesive application workstation 2c and the unloading workstation 2d can move synchronously to simultaneously complete the loading of the battery cell 5 and the unloading of the battery cell assembly 6 in the battery cell assembly device 1, as well as the loading and unloading of the battery cell assembly 6 in the adhesive application device 3. This reduces the downtime of the battery cell assembly device 1 and the adhesive application device 3 and improves production efficiency.

[0060] Furthermore, the first fixture 102 and the second fixture 103 of the battery cell assembly device 1 can simultaneously carry two battery cells 5. Therefore, in order to improve the transfer efficiency of the battery cells 5, the robotic arm 202 between the loading station 2a and the assembly station 2b can simultaneously grasp two battery cells 5 and place the two battery cells 5 synchronously on the first and second fixtures 103 of the battery cell assembly device 1. In addition, the robotic arm 202 in this embodiment is a conventional robotic arm 202 mechanism for grasping and transferring battery cells 5 that is well known to those skilled in the art, and will not be described in detail here.

[0061] In some of the exemplary implementations, combined with Figures 6 to 8As shown, the adhesive applicator 3 includes a third fixture 301 for carrying the battery cell assembly 6, and an adhesive applicator section disposed on at least one side of the third fixture 301. The adhesive applicator section includes a first translation mechanism 302, a second lifting mechanism 303, and an adhesive applicator mechanism. The second lifting mechanism 303 is disposed on the moving end of the first translation mechanism 302, and the adhesive applicator mechanism is disposed on the lifting end of the second lifting mechanism 303.

[0062] With the cooperation of the third tooling 301 and the adhesive application part, the third tooling 301 can stably support the battery cell assembly 6 to be adhesive applied, and the first translation mechanism 302 and the second lifting mechanism 303 in the adhesive application part can effectively drive the adhesive application mechanism to move, thereby achieving precise adhesive application to different parts of the battery cell assembly 6.

[0063] In a specific implementation, the adhesive applicator of this embodiment is mounted on a mounting platform 4, and the first translation mechanism 302 includes a first slide rail 3021 mounted on the mounting platform 4, a first slide table 3022 slidably mounted on the first slide rail 3021, and a translation drive unit located below the mounting platform 4. The drive end of the translation drive unit is connected to the first slide table 3022, enabling it to move along the slide rail to move the adhesive applicator closer to or further away from the third tooling 301.

[0064] To improve the translation accuracy of the adhesive applicator, the translation drive unit of this embodiment includes a translation screw 3023 that is rotatably connected to the mounting platform 4 at both ends and can be driven to rotate, and a translation nut 3024 that is screwed onto the screw and connected to the first slide 3022.

[0065] Based on this, the second lifting mechanism 303 of this embodiment includes a lifting nut 3031 disposed on the first slide 3022, and a lifting screw 3032 extending along the height direction and screwed onto the lifting nut 3031. One end of the lifting screw 3032 is rotatably connected to the substrate 3034 described below, and the adhesive applicator is connected through the substrate 3034. The other end of the lifting screw 3032 is drive-connected to the output shaft of a lifting motor. A fixed frame 3033 is provided below the first slide 3022, and the other end of the lifting screw is rotatably disposed on the fixed frame 3033 and drive-connected to the lifting motor on the fixed frame 3033 through a coupling. When the lifting motor drives the lifting screw 3032 to rotate, the lifting screw can drive the fixed frame 3033, the substrate 3034, and the adhesive applicator to move synchronously in the height direction. Furthermore, guide posts are provided at the four corners of the fixed frame 3033, penetrating the first slide 3022 and connected to the substrate 3034, to ensure the smooth lifting and lowering of the fixed frame 3033 and the substrate 3034.

[0066] Of course, the first translation mechanism 302 and the second lifting mechanism 303 mentioned above can also be other conventional translation and lifting mechanisms known to those skilled in the art, which can drive the adhesive applicator to move in the height and horizontal directions.

[0067] In some exemplary embodiments, the adhesive applicator includes a mounting frame 3041, a tape reel 3042, a tape dispensing roller assembly 3043, and an adhesive applicator plate 3044 disposed on the mounting frame 3041. The adhesive applicator plate 3044 extends laterally and is located on the side of the mounting frame 3041 near the third tooling 301, and the tape dispensing roller assembly 3043 is located between the tape reel 3042 and the adhesive applicator plate 3044. The tape dispensing roller assembly 3043 guides the tape in the tape reel 3042 to the adhesive applicator plate 3044, and the adhesive applicator plate 3044 is driven to move by a first translation mechanism 302 and a second lifting mechanism 303 to attach the tape to the battery cell assembly 6.

[0068] In this embodiment, the adhesive tape is placed on top of the adhesive application plate 3044. Furthermore, the mounting bracket 3041 is equipped with a pressing component 3045 and a cylinder that drives the pressing component 3045 to move. The pressing component 3045 is mounted on the piston rod of the cylinder, and the cylinder can drive the pressing component 3045 to abut against the adhesive tape on top of the adhesive application plate 3044, so as to prevent the adhesive tape from detaching from the adhesive application plate 3044 due to the movement of the entire adhesive application mechanism when the tape is not adhered to the battery cell assembly 6. In addition, the adhesive application plate 3044 integrates a retractable cutter, and the end of the adhesive application plate 3044 facing the third tooling 301 has a through hole for the cutter to extend. The cutter can be driven to extend from the through hole to cut the adhesive tape at the end of the adhesive application plate 3044. The cutter and the driving mechanism driving its movement are conventional structures well known to those skilled in the art, and will not be described in detail here.

[0069] It is understood that the adhesive application mechanism in this embodiment applies adhesive to the battery cell assembly 6 through the following steps.

[0070] First, the first translation mechanism 302 and the second lifting mechanism 303 drive the adhesive applicator 3044 to extend into the bottom of the battery cell assembly 6, and make the top of the adhesive applicator 3044 carrying the tape abut against the bottom of the battery cell assembly 6. At this time, the pressing component 3045 no longer presses the tape. The adhesive applicator 3044 is driven to retract along the width direction of the battery cell assembly 6, so that the adhesive applicator 3044 presses the tape at the bottom of the battery cell assembly 6, and at the same time, the tape is pulled out from the tape reel 3042 due to the movement of the adhesive applicator 3044 relative to the battery cell assembly 6.

[0071] Secondly, the end of the adhesive plate 3044 abuts against the side of the cell assembly 6 and moves upward. At this time, the tape can be attached to the side of the cell assembly 6 and pressed by the end of the adhesive plate 3044.

[0072] Subsequently, the adhesive applicator 3044 moves to the top of the cell assembly 6 and moves towards the center of the cell assembly 6 along the width direction of the cell assembly 6. At this time, some of the adhesive tape will be pulled to the bottom of the pressure plate and then attached to the top of the cell assembly 6 and pressed by the adhesive applicator 3044.

[0073] Finally, when the adhesive plate 3044 moves to the designated position on top of the battery cell 5, the cutter is driven to cut the tape, and the pressing component 3045 is driven to press the tape on top of the adhesive plate 3044. The first translation mechanism 302 and the second lifting mechanism 303 drive the adhesive plate 3044 to reset.

[0074] Therefore, through the arrangement of the tape reel 3042, the glue dispensing roller group 3043, and the adhesive applicator 3044 on the mounting frame 3041, the tape on the tape reel 3042 can be conveyed to the adhesive applicator 3044 through the glue dispensing roller group 3043. At the same time, driven by the first translation mechanism 302 and the second lifting part, the adhesive applicator 3044 is driven to move, and the adhesive applicator 3044 carrying the tape can press the tape onto the bottom, side, and top of the battery cell group 6, thereby bonding the two battery cells 5 in the battery cell group 6 together, realizing the adhesive application of the battery cell group 6. While ensuring the adhesive application quality, it can adapt to battery cell groups 6 of different sizes and has good versatility.

[0075] In addition, in specific implementation, the third tooling 301 of this embodiment is provided with a clamping mechanism, which is similar in structure to the fixing part of the first tooling 102. The support platform of the third tooling 301 carrying the battery cell group 6 is provided with a recessed clearance part 3011 on the side facing the adhesive application mechanism. The adhesive application plate 3044 can extend into the lower part of the battery cell group 6 through the clearance part 3011.

[0076] Furthermore, in this embodiment, the adhesive application section is configured as two units located on opposite sides of the third tooling 301 to apply adhesive to both sides of the battery cell assembly 6, ensuring the connection strength of the two battery cells 5 in the battery cell assembly 6 and further improving the overall integrity of the battery cell assembly 6. The adhesive application section on either side of the third tooling 301 is configured as two units arranged along the length of the battery cell 5. One adhesive application section serves as the primary adhesive application section, while the other serves as a backup adhesive application section to prevent interruption of the adhesive application process due to a failure of a single adhesive application section.

[0077] Meanwhile, the mounting platform 4 is provided with a second slide rail 401 extending along the length of the battery cell 5, and a second slide table 402 is slidably provided on the second slide rail 401. The third tooling 301 is provided on the second slide table 402 so that the third tooling 301 can move between the commonly used adhesive application section and the spare adhesive application section.

[0078] Based on this, the battery cell assembly device 1 of this embodiment includes multiple assembly stations 2b, and the adhesive applicator 3 includes multiple adhesive applicator stations 2c. The length direction of the battery cells 5 in the battery cell assembly device 1 is perpendicular to the extension direction of the frame 201, thereby reducing the space occupied by multiple battery cell assembly devices 1 in the extension direction of the frame 201 and reducing the length of the battery cell production line. Furthermore, since the adhesive applicator sections on both sides of the third fixture 301 in the adhesive applicator 3 occupy a large amount of space, the length direction of the battery cell group 6 in the adhesive applicator 3 is aligned with the extension direction of the frame 201, further reducing the space occupied by multiple adhesive applicator 3 in the extension direction of the frame 201 and further reducing the length of the battery cell production line. During the process of the robot arm 202 transferring the battery cell group 6 to the adhesive applicator 3, the battery cell group 6 needs to be rotated before being placed on the third fixture 301.

[0079] In some exemplary embodiments, the lifting end of the second lifting mechanism 303 is connected to the substrate 3034, and the adhesive application mechanism includes a fixed adhesive application mechanism 304a and a plurality of movable adhesive application mechanisms 304b. The mounting bracket 3041 of the fixed adhesive application mechanism 304a is fixedly connected to the substrate 3034, and a second translation mechanism is provided between the mounting bracket 3041 of the plurality of movable adhesive application mechanisms 304b and the substrate 3034. The second translation mechanism is used to change the spacing between two adjacent adhesive application mechanisms.

[0080] By using the second translation mechanism and the fixed and movable adhesive application mechanism 304b, not only can adhesive be applied to different positions of the battery cell assembly 6 simultaneously, but the movable adhesive application mechanism 304b can also move along the length of the battery cell assembly 6 via the second translation mechanism to change the spacing between the adhesive application mechanisms, adapt to battery cell assemblies 6 of different lengths, and adjust the adhesive application position on the battery cell assembly 6 to meet the application requirements of adhesive application points with different spacing on the battery cell assembly 6.

[0081] In some exemplary embodiments, the second translation mechanism includes a guide rail 305 disposed on a substrate 3034 and a guide rod 306. The mounting brackets 3041 of each movable adhesive applicator 304b are slidably disposed on the guide rail 305. One end of the guide rod 306 is connected to the mounting bracket 3041 of the fixed adhesive applicator 304a, and the mounting brackets 3041 of the multiple movable adhesive applicators 304b are slidably passed through the guide rod 306. Each mounting bracket 3041 of the multiple movable adhesive applicators 304b is provided with a locking member 3046, which restricts the sliding of the mounting bracket 3041 relative to the guide rod 306.

[0082] The guide rail 305 and guide rod 306 work together to ensure smooth sliding of the movable adhesive applicator 304b along the length of the battery cell 5 during position adjustment, thanks to the dual guiding effect of the guide rail 305 and guide rod 306. The locking element 3046 quickly fixes its position, preventing displacement due to vibration or other factors during adhesive application, ensuring the stability of the spacing between each adhesive applicator, and thus improving the consistency of adhesive application quality across multiple locations simultaneously.

[0083] In specific implementation, the locking member 3046 of this embodiment can be a quick-release pipe clamp. The pipe clamp can clamp the guide rod 306 to fix the guide rod 306 and the mounting bracket 3041. Of course, the locking member 3046 can also be other locking mechanisms known to those skilled in the art, which can lock the position of the mounting bracket 3041 on the guide rod 306.

[0084] The battery cell production line in this embodiment, through the coordinated arrangement of the transfer device 2, the battery cell assembly device 1, and the adhesive application device 3, can realize an automated production process of battery cell 5 feeding, assembly, adhesive application, and unloading. This is beneficial to improving the continuity and efficiency of battery cell 5 production. The battery cell assembly device 1 and the adhesive application device 3 can ensure the effect of battery cell 5 assembly and battery cell group 6 adhesive application, which is beneficial to improving the overall quality stability of battery cell 5 production and meeting the needs of large-scale production.
