Description

Technical Field

[0001] The present invention relates to the technical field of battery manufacturing, and particularly relates to an automatic side gluing device for a battery cell strip group. Background Art

[0002] Power batteries are power sources that provide power for tools. Existing new energy vehicles all use power batteries as power sources. Power batteries have the characteristics of ultra-long life, safe use, fast charge and discharge at a large current of 2C, high temperature resistance, large capacity, no memory effect, small size, and light weight. They mainly include lead-acid batteries, nickel-metal hydride power batteries, and lithium-ion power batteries. They are mainly different from starting batteries used for starting automobile engines, and mostly use valve-regulated lead-acid batteries, open-type tubular lead-acid batteries, and lithium iron phosphate batteries.

[0003] Existing power batteries mainly adopt the structure of battery packs. The function of the battery pack is to store electricity and provide power for electric vehicles. The battery pack is assembled by multiple battery cell strip groups. The battery cell strip group is composed of multiple battery cells spliced together. The battery cell is the core component of the battery pack and the main body for energy storage. The battery cell strip group is also called BEAM. During the manufacturing process of the battery cell strip group, multiple battery cells need to be linearly arranged in sequence, and it is necessary to ensure that the multiple battery cells are arranged neatly, and the multiple battery cells are adhered and spliced in sequence. A conductive plate is arranged outside the battery cell strip group, which plays a role in heat transfer and conduction for the multiple battery cells, and the multiple battery cells are adhered and spliced in sequence through a thermally conductive structural adhesive. The thermally conductive structural adhesive makes multiple adjacent battery cells adhere, and the thermally conductive structural adhesive plays a role in heat dissipation protection for adjacent battery cells. Finally, a protective shell is sleeved outside the multiple battery cells to form a power battery pack.

[0004] During the production process of existing battery cell strip groups, a gluing operation is required to splice multiple battery cells through adhesive strips. Most of the existing gluing methods use manual gluing and robotic arm gluing to perform the gluing operation on one adjacent side of multiple battery cells. During this process, if manual gluing is used, it will not only result in low work efficiency, but also cause the adhesive strip to be unable to align with the adjacent side of the battery cell. If the robotic arm gluing method is used, it is necessary to glue one adjacent side of each battery cell, and after gluing, the multiple battery cells are aligned in sequence through subsequent processes and then spliced to form a battery cell strip group. It is necessary to attach adhesive strips to one side to be spliced of each battery cell, resulting in slow production efficiency.

[0024] Compared with the prior art, the present invention provides an automatic glue sticking device for the side surface of a battery cell strip group, and the beneficial effects are as follows: by providing a conveying plane; 2 supporting flat plates; a roller sticking device; and 2 sets of glue supply assemblies; the conveying plane is used for conveying the battery cell strip group, and the glue supply assemblies are used for supplying glue strips. The 2 supporting flat plates are respectively arranged on the outer sides of both sides close to the conveying plane, so that the 2 supporting flat plates are flush. The 2 sets of glue supply assemblies are respectively close to one end of the 2 supporting flat plates. By providing a glue pulling device at both ends of the 2 supporting flat plates, the glue pulling device is slidably arranged directly above the supporting flat plates. The glue strip is pulled by a glue pulling assembly. By providing a cutting device at the end of the supporting flat plate close to the glue supply assembly, the cutting device is corresponding to the glue outlet end of the glue supply assembly.

By providing a linear guide rail directly above the bearing flat plate, one surface of the sliding flat plate is arranged on the slider of the linear guide rail, and one end of the linear guide rail is close to the supporting flat plate. Thus, the sliding flat plate can be driven to move by the linear guide rail, and the sliding flat plate can be driven to slide close to the supporting plate member. The lifting plate member is movably arranged on the other surface of the sliding flat plate. By providing a jacking mechanism at the top of the sliding flat plate, the power output end of the jacking mechanism is connected to the bottom of the lifting plate member.

Both of the two glue clamping mechanisms are arranged on the power output end of the moving mechanism. After the glue taking device completes the glue taking action, by moving the sliding flat plate to be directly below the two glue clamping mechanisms and aligning the clamping openings of the two glue clamping mechanisms, it is convenient to clamp both ends of the rubber strip. By driving the glue taking clamp fingers again through the rotating mechanism, at this time, the rubber strip on the glue taking clamp fingers is in a vertical state, making the glue taking clamp fingers align with the clamping openings of the two glue clamping mechanisms. After alignment, the lifting mechanism drives the lifting plate member to rise again, bringing the two glue taking clamp fingers closer to the space between the two glue clamping mechanisms, so that the two glue clamping mechanisms can clamp both ends of the rubber strip on the glue taking clamp fingers. When the two glue clamping mechanisms clamp the rubber strip on the glue taking clamp fingers, the glue taking clamp fingers release the rubber strip. The moving mechanism drives the two glue clamping mechanisms to approach the battery cell strip group on the transportation plane. Also, a rubber rolling mechanism is arranged outside one of the glue clamping mechanisms. The rubber rolling mechanism includes a jacking cylinder and a rubber rolling roller. The rubber rolling roller is arranged on the power output end of the jacking cylinder, and the rubber rolling roller is outside near the transportation plane. The jacking cylinder drives the rubber rolling roller to push the rubber strip, making the rubber strip close to the side of the battery cell strip group on the transportation plane. During the process of the transportation plane driving the battery cell strip group to move, the rubber pasting action is completed, effectively realizing the full-automatic synchronous rubber pasting action on both sides of the battery cell strip group, and ensuring that the length dimension of the rubber strip is adapted to the length dimension of the battery cell strip group, effectively improving the working efficiency.

Therefore, glue strips can be supplied through the glue supply components 4. At the other ends of the two support plates 2, glue pulling devices 5 are arranged. The glue pulling devices 5 are slidably arranged directly above the support plates 2. Also, at the end of the support plate 2 close to the glue supply component 4, a cutting device 6 is arranged. The cutting device 6 is corresponding to the glue outlet end of the glue supply component 4, and the glue pulling device 5 is aligned with the cutting device 6. Therefore, the glue pulling device 5 can be used to pull the glue strip. After ensuring that the pulled length dimension of the glue strip is consistent with the length dimension of the battery cell strip group, the cutting device 6 is used to cut the glue strip.

[0060] It should be noted that linear drive modules 21 are arranged directly above the two support plates 2, and the two glue pulling devices 5 are respectively arranged on the moving sliders of the two linear drive modules 21. Therefore, the two linear drive modules 21 can be used to respectively control the moving distances of the two glue pulling devices 5. When it is necessary to pull the glue strips at the glue outlet ends of the two groups of glue supply components 4, the two linear drive modules 21 respectively drive the two glue pulling devices 5 to move, so that the glue pulling devices 5 are all close to the glue outlet ends, that is: the glue pulling devices 5 move towards the cutting device 6, so as to facilitate the glue pulling devices 5 to clamp the end parts of the glue strips at the glue outlet ends. And then the two linear drive modules 21 respectively drive the two glue pulling devices 5 to reset again to complete the glue strip pulling action. The moving distance of the glue pulling device 5 can be controlled according to the length dimension of the battery cell strip group, that is: the distance dimension between the glue pulling device 5 and the cutting device 6 is equal to the length dimension of the glue strip.

[0061] It should be noted that the glue supply component 4 includes a glue supply roller 41 and a film winding roller 42. The film winding roller 42 is arranged outside close to the glue supply roller 41. The glue supply roller 41 can be used to supply glue strips, and the film winding roller 42 can also be used to recycle the release paper. The glue supply roller 41 of the glue supply component 4 supplies glue strips, and the end parts of the glue strips are discharged through the glue outlet end, so as to facilitate the glue pulling device 5 to clamp and pull the end parts of the glue strips. And during the process of supplying glue strips, the release paper can be recycled through the film winding roller 42. Since the release paper is arranged on the sticky side of the glue strip, the release paper needs to be recycled during the unwinding process; the release paper, also known as silicon oil paper and anti-sticking paper, mainly plays a role in isolating sticky objects. When using the tape, the release paper needs to be peeled off, and then the release paper can be recycled through the film winding roller 42.

[0062] It should be noted that the glue pulling device 5 includes a mounting base plate 51 and glue pulling clamp fingers 52. The bottom of the mounting base plate 51 is arranged on the moving slider of the linear drive module 21, and the glue pulling clamp fingers 52 are also arranged on the top of the mounting base plate 51, so that the clamping opening of the glue pulling clamp fingers 52 faces the cutting device 6. Therefore, when it is necessary to obtain the rubber strip at the glue outlet end of the glue supply assembly 4, the linear drive module 21 can drive the mounting base plate 51 to move towards one end of the glue pulling clamp fingers 52. When the glue pulling clamp fingers 52 approach the cutting device 6 during the movement, the glue pulling clamp fingers 52 can clamp one end of the rubber strip at the glue outlet end, and the linear drive module 21 can drive the glue pulling clamp fingers 52 to reset again. During this process, a certain length of the rubber strip is pulled out from the glue outlet end. The length of the rubber strip can be controlled by adjusting the distance between the glue pulling clamp fingers 52 and the cutting device 6, so that the length of the rubber strip can be adapted to the length of the battery cell strip group. At this time, after the glue pulling is completed, the glue taking device 8 approaches the pulled-out rubber strip, clamps and fixes the rubber strip with a certain size, and the glue taking device 8 performs a glue taking action on the rubber strip clamped by the glue pulling device 5. After the glue taking device 8 clamps the rubber strip, the cutting device 6 cuts the rubber strip at the glue outlet end to complete the glue taking of the rubber strip, so as to facilitate the subsequent movement of the glue taking device 8 close to the roller pasting device 3 and perform the subsequent pasting action on the side of the battery cell strip group.

[0063] It should also be noted that the cutting device 6 includes a flattening component 61 and a supporting vertical plate 62. An adhesive outlet opening 621 is provided at the center of the supporting vertical plate 62, and the adhesive outlet opening 621 is aligned with the adhesive outlet end of the glue supply assembly 4, so that when the glue supply assembly 4 supplies the rubber strip, the rubber strip can enter the adhesive outlet opening 621. The flattening component 61 is arranged on one side of the supporting vertical plate 62. The flattening component 61 includes a pressing plate member 611 and a force-bearing flat plate 612. A pushing cylinder 613 is arranged directly above the pressing plate member 611, and the power output end of the pushing cylinder 613 is connected to the top of the pressing plate member 611. The pressing plate member 611 is located directly above the force-bearing flat plate 612. Therefore, the pushing cylinder 613 can be used to control the lifting distance of the pressing plate member 611. When it is necessary to cut the rubber strip after the glue pulling device 5 pulls a certain length, the pushing cylinder 613 can be started to drive the pressing plate member 611 to move towards the force-bearing flat plate 612. When one side of the pressing plate member 611 fits with one side of the force-bearing flat plate 612, the action of pressing the rubber strip is completed, thereby preventing the situation that the rubber strip cannot maintain a straightened state due to the shaking of the rubber strip during the cutting process of the rubber strip. The flattening component 61 can effectively ensure that the cut of the rubber strip is straight. A moving cutter 622 is slidably arranged on the other side of the supporting vertical plate 62, and the moving cutter 622 corresponds to the adhesive outlet opening 621 to cut the rubber strip at the adhesive outlet opening 621.

[0064] Regarding the above description, it should be added that when the rubber strip is pulled out by a certain dimension, the moving cutter 622 needs to be moved, and then the rubber strip at the glue outlet 621 is cut. By further providing a transmission screw rod 623 and a stepping motor 624 on the supporting vertical plate 62, the transmission screw rod 623 is rotatably arranged on the supporting vertical plate 62 so that both ends of the transmission screw rod 623 are flush with both ends of the glue outlet 621. The power output end of the stepping motor 624 is connected to the transmission screw rod 623. Therefore, the transmission screw rod 623 can be driven to rotate by the stepping motor 624. A sliding plate is sleeved outside the transmission screw rod 623, and the moving cutter 622 is connected to the sliding plate. During the rotation of the transmission screw rod 623, the moving cutter 622 is driven to perform a linear movement, and then the rubber strip at the glue outlet 621 is transversely cut.

[0065] In combination with the above description, it is particularly added that a clamping assembly can be provided on one surface of the supporting vertical plate 62, and the two clamping plates of the clamping assembly are respectively located at the top and bottom of the glue outlet 621. Therefore, before the moving cutter 622 cuts the rubber strip at the glue outlet 621, the rubber strip can be clamped by the clamping assembly, so that when the rubber strip is cut, the rubber strip will not fall off, maintaining the straight state of the rubber strip, preventing the rubber strip from curling and sticking, and facilitating the subsequent movement of the glue taking device 8 close to the rubber strip to take the glue.

[0066] In the second embodiment, to automatically perform the rubber strip pasting operation on both sides of the battery cell strip group to improve work efficiency, in this embodiment: The roller pasting device 3 is located directly above the glue taking device 8, and the roller pasting device 3 is also arranged outside and close to the transportation plane 1. The roller pasting device 3 includes a moving mechanism 31 and two rubber strip clamping mechanisms 32. The two rubber strip clamping mechanisms 32 are both arranged on the power output end of the moving mechanism 31, and the clamping ports of the two rubber strip clamping mechanisms 32 are aligned. A rubber strip rolling mechanism 33 is arranged outside one of the two rubber strip clamping mechanisms 32. The rubber strip rolling mechanism 33 includes a jacking cylinder 331 and a rubber strip rolling roller 332. The rubber strip rolling roller 332 is arranged on the power output end of the jacking cylinder 331, and the rubber strip rolling roller 332 is close to the outside of the transportation plane 1. When the glue taking device 8 moves to directly below the roller pasting device 3 and the two glue taking fingers 85 are aligned with the two rubber strip clamping mechanisms 32 one by one, the moving mechanism 31 can drive the two rubber strip clamping mechanisms 32 to approach both ends of the rubber strip between the two glue taking fingers 85 and clamp both ends of the rubber strip. At this time, the two glue taking fingers 85 are simultaneously loosened. The moving mechanism 31 drives the two rubber strip clamping mechanisms 32 to move closer to the outer sides of the battery cell strip group on the transportation plane 1 again, and aligns the two rubber strip clamping mechanisms 32 with both ends of the side of the battery cell strip group. And by the rubber strip rolling mechanism 33 pushing the non-sticky side of the rubber strip, the sticky side of one end of the rubber strip is attached to the side of the battery cell strip group. Therefore, during the movement of the battery cell strip group, the rubber strip rolling roller 332 rotates along with the side of the battery cell strip group until the whole rubber strip is completely attached to the side of the battery cell strip group;

[0067] Since a bearing plate 7 is provided between each of the two supporting plates 2 and the transportation plane 1, and a glue taking device 8 is slidably arranged directly above the bearing plate 7, and the roller pasting device 3 is arranged directly above the glue taking device 8, that is, there are 2 roller pasting devices 3, and the two sides of the battery cell strip group can be respectively corresponded to by the two roller pasting devices 3, so that the glue strip pasting action can be effectively realized on the two sides of the battery cell strip group.

[0068] It should be noted that the moving mechanism 31 includes a double-slider moving module 311 and two longitudinal moving modules 312. The two ends of the double-slider moving module 311 are respectively arranged on the moving sliders of the two longitudinal moving modules 312. Therefore, the two longitudinal moving modules 312 can synchronously drive the two ends of the double-slider moving module 311 to move synchronously. Since one ends of the two longitudinal moving modules 312 are both close to the outside of the transportation plane 1, the double-slider moving module 311 can be driven to approach the side surface of the battery cell strip group on the transportation plane 1. The two glue clamping mechanisms 32 are respectively arranged on the two sliders of the double-slider moving module 311, so that the double-slider moving module 311 can be used to control the moving distance of the two glue clamping mechanisms 32. The double-slider moving module 311 can independently control the movement of any one of the glue clamping mechanisms 32 to realize the adjustment of the distance between the two glue clamping mechanisms 32.

[0069] It should be noted that in order to prevent the situation that when one end of the glue strip is attached to the side surface of the battery cell strip group, if the other end of the glue strip remains stationary, the glue strip will be pulled off or fall off. Therefore, the glue clamping mechanism 32 for clamping the other end of the glue strip will move slowly along with the conveying direction of the battery cell strip group, that is, the glue clamping mechanism 32 for clamping the other end of the glue strip moves towards the glue rolling mechanism 33 until the whole glue strip is completely attached to the side surface of the battery cell strip group, and then the glue clamping mechanism 32 releases the other end of the glue strip.

[0070] It should also be noted that in order to ensure the two sides of the battery cell strip group are flush, the two sides of the battery cell strip group need to be pressure-maintained before the battery cell strip group enters the pasting station, and when the battery cell strip group exits the pasting station, the glue strips on the two side surfaces of the battery cell strip group need to be pressure-maintained to ensure that the glue strips are tightly attached to the two side surfaces of the battery cell strip group and reduce the occurrence of falling off. In this embodiment, a pressing wheel group 11 is further arranged at the discharging end of the transportation plane 1, and there are 2 pressing wheel groups 11. The two pressing wheel groups 11 are symmetrically arranged outside the transportation plane 1. The two supporting plates 2 are both located between the two pressing wheel groups 11. The distance dimension between the two pressing wheel groups 11 is adapted to the width dimension of the battery cell strip group. The pressing wheel group 11 includes a plurality of guiding pressing wheels, and all the plurality of guiding pressing wheels are tangent to the side surface of the battery cell strip group. Therefore, one of the pressing wheel groups 11 can be used to press the battery cell strip group entering the pasting station, and the other pressing wheel group 11 can be used to perform glue strip pressure-maintenance on the battery cell strip group exiting the pasting station.

[0071] Embodiment 3. To automatically perform the glue-taking action on the rubber strip, since the rubber strip is discharged in a flat state from the glue outlet end of the glue supply component 4, after the rubber strip of a certain length dimension is pulled out by the rubber strip pulling device 5, it is necessary to take the pulled-out rubber strip and perform a flipping action on the rubber strip to make the rubber strip in a vertical state, so as to facilitate the roller pasting device 3 to clamp and take the glue and paste the glue on the side of the battery cell strip group, ensuring that the sticky side of the rubber strip is aligned with the side of the battery cell strip group. In this embodiment: A bearing flat plate 7 is provided between the two support flat plates 2 and the transport plane 1, and a glue-taking device 8 is slidably provided directly above the bearing flat plate 7. The glue-taking device 8 includes a sliding flat plate 81 and a lifting plate member 82. A linear guide rail 71 is provided directly above the bearing flat plate 7. One side of the sliding flat plate 81 is arranged on the slider of the linear guide rail 71. Therefore, the moving distance of the sliding flat plate 81 can be controlled by the linear guide rail 71. Since one end of the linear guide rail 71 is close to the support flat plate 2, the sliding flat plate can be driven by the linear guide rail 71 to approach the support flat plate 2. The lifting plate member 82 is movably arranged on the other side of the sliding flat plate 81. A jacking mechanism 83 is further provided on the top of the sliding flat plate 81, and the power output end of the jacking mechanism 83 is connected to the bottom of the lifting plate member 82. Rotating mechanisms 84 are provided at both ends of the top of the lifting plate member 82, and glue-taking clamp fingers 85 are provided at the power output ends of the rotating mechanisms 84. Therefore, after the sliding plate member approaches the support flat plate 2, the jacking mechanism 83 drives the lifting plate member 82 to lift and lower, so that the glue-taking clamp fingers 85 are aligned with the outside of the pulled-out rubber strip. The rotating mechanism 84 is used to control the rotation direction of the glue-taking clamp fingers 85, thereby ensuring that the clamping openings of the glue-taking clamp fingers 85 are aligned with the side surfaces of the pulled-out rubber strip. The glue-taking clamp fingers 85 are used to clamp the cut rubber strip and drive the cut rubber strip to complete the glue-taking action.

[0072] After the glue-taking action is completed, the rotating mechanism 84 drives the glue-taking clamp fingers 85 to rotate again, realizing that the tape rotates to a vertical state. At this time, the linear guide rail 71 drives the sliding plate member to move back to its original position, so that the glue-taking clamp fingers 85 move towards the roller pasting device 3. The jacking mechanism 83 can drive the lifting plate member 82 to descend again to prevent the glue-taking clamp fingers 85 from directly colliding with the roller pasting device 3. Effectively, the rubber strip on the glue-taking clamp fingers 85 is aligned with the clamping end of the roller pasting device 3. When the roller pasting device 3 takes the rubber strip on the glue-taking device 8, the glue-taking clamp fingers 85 are loosened and move closer to the support flat plate 2 again to take the next rubber strip, realizing a continuous production operation and effectively improving the work efficiency.

[0073] Among them, the linear guide rail 71, also known as a slide rail, linear guide rail, or linear slide rail, is used to support and guide moving parts to perform reciprocating linear motion in a given direction.

[0074] Specifically, the rotating mechanism 84 can adopt a servo motor. The glue-taking clamp fingers 85 can be fixed on the power output end of the servo motor. Furthermore, the rotation direction of the glue-taking clamp fingers 85 can be controlled by the servo motor. When it is necessary to take glue from the support flat plate 2, the glue-taking clamp fingers 85 need to be rotated so that the clamping opening of the glue-taking clamp fingers 85 faces the glue strip on the support flat plate 2. The lifting mechanism 83 drives the lifting plate member 82 to rise, so that the clamping opening of the glue-taking clamp fingers 85 on the lifting plate member 82 and the glue strip on the support flat plate 2 are located on the same horizontal plane.

[0075] Embodiment 4: To realize the automatic edge folding action of the bottom edge of the glue strip of the cell strip group after gluing. Since the power battery pack places multiple cell strip groups in the battery frame, in order to ensure that the cell strip groups can be fixed in the battery frame conveniently later, the bottom of the battery strip group also needs to be fixed. Furthermore, the edge folding action needs to be performed on the protruding edge of the glue strip attached to the side of the cell strip group. The bottom of the battery strip group is fixed by the glue strip. In this embodiment: A folding wheel group 10 is also provided directly below the transportation plane 1. The folding wheel group 10 includes a plurality of folding rollers 101. The plurality of folding rollers 101 are all tangent to the transportation plane 1. The plurality of folding rollers 101 are arranged along the conveying direction of the transportation plane 1. The guide angles of the plurality of folding rollers 101 are arranged in increasing order. Therefore, when the cell strip group on the transportation plane 1 moves, the glue strip edge at the bottom of the cell strip group is tangent to the folding rollers 101. Since the guide angles between the folding rollers 101 increase in sequence, the contact surface between the folding rollers 101 and the glue strip edge gradually increases. During the movement of the cell strip group, the edge folding action of the glue strip edge at the bottom of the cell strip group is completed.

[0076] For this embodiment, it is further supplemented that the folding wheel group 10 needs to be arranged between the discharge end of the transportation plane 1 close to the transportation plane 1 and the gluing station, and the folding wheel group 10 is close to the gluing station. Furthermore, after gluing is completed, the cell strip group can move towards the folding wheel group 10, and the bottom glue strip of the cell strip group will perform the edge folding action along the folding wheel group 10.

[0077] Embodiment 5: To automatically clamp, transfer, align and perform a gluing operation on the battery cell strip group using the roller pasting device 3, and after the gluing is completed, clamp and transfer the battery cell strip group again to move the battery cell strip group out of the gluing station. In this embodiment: Two fixed cross plates 9 are further provided directly above the transportation plane 1, and the two fixed cross plates 9 are respectively aligned with both ends of the transportation plane 1. Two linear modules 91 are movably arranged between the two fixed cross plates 9. Connecting vertical plates 92 are provided on the moving sliders of the two linear modules 91. A pushing mechanism 93 is further provided on the connecting vertical plates 92, and a battery cell clamping cylinder 94 is provided at the power output end of the pushing mechanism 93, so that the battery cell clamping cylinder 94 corresponds to directly above the transportation plane 1. Therefore, the two ends of the battery cell strip group can be clamped by the battery cell clamping cylinder 94. Furthermore, the moving distances of the two connecting vertical plates 92 can be controlled respectively by the two linear modules 91 to ensure that the two fingers of the battery cell clamping cylinder 94 are respectively aligned with both ends of the battery cell strip group, so as to clamp the battery cells to ensure that multiple battery cells are tightly attached to each other. The linear module 91 can drive the battery cell clamping cylinder 94 to move, so that the battery cell strip group moves on the transportation plane 1.

[0078] It should be noted that to control the movement of the two linear modules 91 on the fixed cross plate 9, a guiding rack 95 is provided on one side of the two fixed cross plates 9 facing the linear modules 91, and the guiding rack 95 is arranged to extend along the length direction of the fixed cross plate 9. Driving motors 96 are provided at both ends of the two linear modules 91, and the power output ends of the driving motors 96 are meshed with the guiding rack 95. When the driving motors 96 are started, the linear modules 91 can move on the fixed cross plate 9. Therefore, the moving distance of the linear modules 91 can be controlled by the driving motors 96 to align the linear modules 91 with the battery cell strip group on the transportation plane 1.

[0079] When the driving motors 96 rotate, since the power output ends of the driving motors 96 are meshed with the guiding rack 95, the driving motors 96 can drive the two linear modules 91 to move on the fixed cross plate 9, so that the two linear modules 91 approach the battery cell strip group on the transportation plane 1. Furthermore, it is convenient for the battery cell clamping cylinders 94 on the two connecting vertical plates 92 to align with the battery cell strip group on the transportation plane 1. Then, the pushing mechanism 93 drives the battery cell clamping cylinder 94 to move towards the transportation plane 1 to clamp the battery cell strip group, ensuring that the multiple battery cells in the battery cell strip group are pressed tightly against each other before the gluing process, so that there are no gaps between the multiple battery cells, ensuring the accurate length dimension of the battery cell strip group. Furthermore, when gluing later, it is convenient to ensure that the length dimension of the glue strip is consistent with the length dimension of the battery cell strip group. The connecting vertical plate 92 is driven to move by the moving module, so that the battery cell strip group moves.

[0080] It should be noted that the two battery cell clamping cylinders 94 are respectively arranged at both ends close to the transport plane 1. One of the battery cell clamping cylinders 94 is used to clamp the battery cell strip group, drive the battery cell strip group into the gluing station, and then reset to the end of the transport plane 1. Then it drives the next group of battery cell strip groups into the gluing station again. The other battery cell clamping cylinder 94 is used to clamp the battery cell strip group after gluing and move it out of the gluing station, ensuring the control of the gluing station, facilitating the entry of the next group of battery cell strip groups into the gluing station, effectively realizing continuous operation, and improving production efficiency.

[0081] Combined with the above embodiments, in order to prevent the adhesive side of the rubber strip from sticking to the clamping surface and pressing surface during the process of clamping and pressing the rubber strip, resulting in the situation of rubber strip adhesion, an anti-sticking coating can be sprayed on the clamping surfaces of the flattening assembly 61, the clamping assembly, the rubber strip pulling clamp fingers 52, the rubber strip picking clamp fingers 85, and the rubber strip clamping mechanism 32. The anti-sticking coating is used to prevent the rubber strip from sticking to the clamping surface.
