[0050] See also Figure 1 and Figure 8 In one embodiment of the present invention, a solid-state battery gluing device 10 includes a glue preparation device 100 , a tape laminating device 200 and a glue supporting device 300 .

[0051] The adhesive preparation device 100 is used to provide adhesive tape 30 of a preset length. The adhesive support device 300 includes an adhesive application platform 310, which can support the battery cell 20 to be adhesively applied. The adhesive tape application device 200 applies the adhesive tape 30 provided by the adhesive preparation device 100 to the surface of the battery cell 20 supported on the adhesive application platform 310. The battery cell 20 includes a large surface area and side areas. The length and width of the adhesive tape 30 are generally required to be greater than the length and width of the battery cell 20 to ensure that the adhesive tape 30 can effectively cover the large surface area and side areas of the battery cell 20.

[0052] In addition, in this embodiment, the solid-state battery adhesive laminating device 10 further includes a transfer device (not shown), and the tape laminating device 200 is mounted on the movable end of the transfer device. Moreover, the transfer device can drive the tape laminating device 200 to move between the adhesive preparation device 100 and the adhesive laminating support device 300.

[0053] The transfer device can be a robotic arm or a combination of a guide rail and a motor. When the transfer device drives the tape laminating device 200 toward the adhesive preparation device 100, it facilitates the tape laminating device 200 to obtain the adhesive tape 30. Furthermore, when the transfer device drives the tape laminating device 200 toward the adhesive laminating support device 300, it facilitates the tape laminating device 200 to apply the obtained adhesive tape 30 to the surface of the battery cell 20 supported on the adhesive laminating platform 310.

[0054] It should be noted that, in other embodiments, the tape applying device 200 may remain in a fixed position, while the glue preparation device 100 and the glue application support device 300 can move relative to the tape applying device 200. The glue preparation device 100 and the glue application support device 300 can each be moved within the operating range of the tape applying device 200 to facilitate the tape applying device 200 to smoothly obtain and apply the tape 30.

[0055] The adhesive preparation device 100 can use the protective adhesive tape 30 material strip to prepare the adhesive tape 30 in real time, or it can pre-cut and store a plurality of adhesive tapes 30, and then provide the stored adhesive tape 30 to the adhesive tape applying device 200 when the adhesive application process is initiated. Specifically, in this embodiment, the adhesive preparation device 100 can use the protective adhesive tape to cut the adhesive tape 30 into predetermined lengths in real time, and provide the cut adhesive tapes to the adhesive tape applying device 200 one by one. In this way, the adhesive tape 30 does not need to be stacked and stored after being cut and formed, thereby effectively preventing the adhesive tape 30 from sticking together during storage, which could ultimately prevent the adhesive tape applying device 200 from being able to obtain the adhesive tape 30 after the adhesive application process is initiated.

[0056] Please also refer to Figure 2 and Figure 3 In this embodiment, the adhesive preparation device 100 includes an unwinding mechanism 110, an adhesive preparation plate 120, an adhesive pulling mechanism 130, and a cutting mechanism 140. The cutting mechanism 140 includes a cutter 141, which is located between the unwinding mechanism 110 and the adhesive preparation plate 120. The cutter 141 can be a mechanical blade, a hot cutter, or a laser cutter, and is capable of cutting the protective adhesive tape.

[0057] The unwinding mechanism 110 generally includes an unwinding shaft for unwinding the protective adhesive tape. The adhesive pulling mechanism 130 generally includes a chuck and an adhesive pulling drive. Driven by the adhesive pulling drive, the chuck can move back and forth between the side of the adhesive preparation board 120 facing the unwinding mechanism 110 and the side away from the unwinding mechanism 110. When preparing the adhesive tape 30, the chuck first moves to the side of the adhesive preparation board 120 facing the unwinding mechanism 110 and clamps the starting end of the protective adhesive tape 30; then moves to the side away from the unwinding mechanism 110 and pulls the protective adhesive tape 30 onto the adhesive preparation board 120; the adhesive preparation board 120 supports the protective adhesive tape; finally, the cutter 141 cuts the protective adhesive tape to obtain the adhesive tape 30 carried on the adhesive preparation board 120.

[0058] Specifically, in this embodiment, the surface of the adhesive preparation board 120 has multiple air holes (not shown). Air can be blown toward the adhesive tape 30 carried on the adhesive preparation board 120 through the air holes, thereby preventing the adhesive tape 30 from adhering to the adhesive preparation board 120 and facilitating the tape laminating device 200 to smoothly remove the adhesive tape 30 from the adhesive preparation board 120. During the preparation of the adhesive tape 30, a protective adhesive tape can be first pressed against the adhesive preparation board 120 using the tape laminating device 200 or another device. This ensures that the protective adhesive tape is securely fixed during the cutting process and prevents the produced adhesive tape 30 from being blown away.

[0059] In this embodiment, the cutting mechanism 140 further includes a tape 30 clamping assembly 142, which is disposed on the side of the cutter 141 facing the unwinding mechanism 110. The clamping assembly 142 can employ a structure such as a clamping plate or a chuck to clamp the protective tape 30. The protective tape unwound by the unwinding mechanism 110 first passes through the clamping assembly 142 before being gripped and pulled by the adhesive pulling mechanism 130.

[0060] After the adhesive drawing mechanism 130 draws the protective tape 30 onto the adhesive preparation board 120, the clamping assembly 142 first clamps the protective tape 30, and then the cutter 141 cuts the protective tape to obtain the adhesive tape 30. On the one hand, the action of the clamping assembly 142 can ensure that the protective tape 30 maintains greater stability during the cutting process, thereby improving the cutting effect and ensuring that the size of the adhesive tape 30 obtained by multiple cuts is consistent. On the other hand, after the protective tape 30 is cut, the new starting end will be clamped and fixed by the clamping assembly 142, ensuring that the adhesive drawing mechanism 130 can successfully clamp the starting end of the protective tape again to prepare the next adhesive tape 30.

[0061] In this embodiment, the cutting mechanism 140 further includes a position adjustment assembly 143, and the cutter 141 is mounted on the movable end of the position adjustment assembly 143. The position adjustment assembly 143 can drive the cutter 141 to move between the unwinding mechanism 110 and the adhesive preparation plate 120, thereby adjusting the length of the cut tape 30.

[0062] Specifically, the position adjustment assembly 143 can employ a structure combining a guide rail and a slider. The cutter 141 is mounted on the slider, and the slider slides along the guide rail to drive the cutter 141 to translate between the unwinding mechanism 110 and the rubber preparation plate 120. More specifically, a support plate (not shown) is provided on the slider, and the cutter 141 and the clamping assembly 142 are both mounted on the support plate. In other words, the clamping assembly 142 and the cutter 141 can translate synchronously with the support plate, thereby maintaining their relative position.

[0063] In this embodiment, the adhesive preparation device 100 further includes a tape buffer mechanism 150, which is disposed between the cutting mechanism 140 and the unwinding mechanism 110. The protective adhesive tape unwound by the unwinding mechanism 110 first passes through the tape buffer mechanism 150 and then through the cutting mechanism 140. The tape buffer mechanism 150 can buffer or release the protective adhesive tape, thereby ensuring that the tension of the protective adhesive tape remains stable, further improving the cutting effect of the cutting mechanism 140.

[0064] Specifically, the tape buffer mechanism 150 generally includes multiple rollers (not shown), through which the protective tape can be sequentially passed. The relative positions of the rollers are adjustable, thereby varying the length of the protective tape within the tape buffer mechanism 150 to achieve buffering or release of the protective tape.

[0065] In addition, in this embodiment, the glue preparation device 100 further includes a second lifting mechanism 160 , and the second lifting mechanism 160 is transmission-connected to the glue preparation plate 120 .

[0066] Specifically, the second lifting mechanism 160 is generally capable of driving the rubber preparation plate 120 to rise and fall in a direction perpendicular to the supporting surface of the rubber preparation plate 120, generally in a vertical direction. While the strapping mechanism 120 is moving back and forth between the two sides of the rubber preparation plate 120, the second lifting mechanism 160 can first drive the rubber preparation plate 120 downward to prevent the rubber preparation plate 120 from interfering with the travel of the strapping mechanism 120. Once the strapping mechanism 120 is in place, the second lifting mechanism 160 then drives the rubber preparation plate 120 upward until the protective tape pulled by the strapping mechanism 120 is supported on the rubber preparation plate 120.

[0067] It should be noted that in other embodiments, the second lifting mechanism 160 can also be connected to the draw mechanism 120. Before pulling the protective tape, the second lifting mechanism 160 can first drive the draw mechanism 120 upward, thereby preventing the rubber preparation plate 120 from interfering with the travel of the draw mechanism 120. After the draw mechanism 120 is in place, the second lifting mechanism 160 then drives the draw mechanism 120 downward until the pulled protective tape is placed on the rubber preparation plate 120.

[0068] Please also refer to Figure 4 In one embodiment of the present invention, a tape laminating device 200 includes a support frame 210 , a side pressure mechanism 220 , a glue suction plate 230 and a first lifting mechanism 240 .

[0069] The support frame 210 can provide a large installation space for the side pressure mechanism 220, the glue suction plate 230, etc. Among them, the first lifting mechanism 240 is connected to the support frame 210, and the first lifting mechanism 240 can drive the support frame 210 to rise and fall. The lifting direction of the first lifting mechanism 240 is generally perpendicular to the adsorption surface of the glue suction plate 230, and is roughly in the vertical direction. When the support frame 210 is raised and lowered, it can also drive the side pressure mechanism 220 and the glue suction plate 230 to rise and fall. Similarly, the first lifting mechanism 240 can use a cylinder, an electric cylinder, or a motor screw pair to drive the support frame 210, and the specific form is not limited. Of course, the support frame 210 can also be not set up separately, and the first lifting mechanism 240 can directly drive the side pressure mechanism 220 and the glue suction plate 230 to rise and fall.

[0070] Specifically, in this embodiment, the tape applying device 200 further includes a large plate 260, the first lifting mechanism 240 is fixed to the large plate 260, and the support frame 210 is slidably mounted on the large plate 260. The large plate 260 supports the first lifting mechanism 240, the support frame 210, and other components. The support frame 210 is slidably mounted on the large plate 260 via guide rails and sliders. Therefore, the support frame 210 can maintain high stability during the process of being raised and lowered by the first lifting mechanism 240.

[0071] The side pressure mechanism 220 comprises a first side pressure member 221, a second side pressure member 222 and a side pressure driver 223. Wherein, the first side pressure member 221 and the second side pressure member 222 are in transmission connection with the side pressure driver 223. More specifically, the first side pressure member 221 and the second side pressure member 221 are slidably arranged relatively on the support frame 210, and the side pressure driver 223 can drive the first side pressure member 221 and the second side pressure member 222 to move closer to or away from each other. The side pressure driver 223 can adopt a clamping claw cylinder etc. to realize driving, and the first side pressure member 221 and the second side pressure member 222 can be installed on the support frame 210 by means of guide rail and slide block cooperation. Of course, when the support frame 210 is not provided, the first side pressure member 221 and the second side pressure member 222 can directly be installed on two clamping claws of the clamping claw cylinder.

[0072] The adhesive suction plate 230 has an adsorption surface capable of absorbing the adhesive tape 30. Specifically, the adsorption surface of the adhesive suction plate 230 may be provided with multiple vacuum cups or multiple adsorption holes. Furthermore, the adhesive suction plate 230 is positioned between the first side pressure member 221 and the second side pressure member 222. The adhesive suction plate 230 may be mounted directly on the support frame 210, mounted on the large plate 260 and connected to the support frame 210, or mounted on the side pressure mechanism 220.

[0073] When the adhesive preparation device 100 prepares the adhesive tape 30, the adhesive suction plate 230 first moves above the adhesive preparation plate 120 and then, driven by the first lifting mechanism 240, descends until the protective adhesive tape is pressed against the adhesive preparation plate 120, thereby securing the protective adhesive tape. After the cutting mechanism 140 cuts the protective adhesive tape, the resulting adhesive tape 30 is adsorbed on the adhesive suction plate 230, allowing the tape applying device 200 to quickly obtain the adhesive tape 30.

[0074] When gluing the battery cell 20, the glue absorbing plate 230 first obtains the adhesive tape 30 provided by the glue preparation device 100; then the glue absorbing plate 230 is moved above the glue laminating platform 310, and the first lifting mechanism 240 drives the support frame 210 to drive the glue absorbing plate 230 and the side pressing mechanism 220 to move toward the glue laminating platform 310 until the glue absorbing plate 230 presses the sucked adhesive tape 30 on the large surface area of ​​the battery cell 20. Figure 8 As shown in (a), the tape 30 can generally extend beyond the edge of the battery cell 20 .

[0075] The adhesive absorbing plate 230 is kept in contact with the large surface area of ​​the battery cell 20, so that the adhesive tape 30 is attached to the large surface area of ​​the battery cell 20, and the first side pressing member 221 and the second side pressing member 222 are able to press down the portion of the adhesive tape 30 extending from the edge of the battery cell 20. The side pressing driving member 223 then drives the first side pressing member 221 and the second side pressing member 222 closer to each other, so that the adhesive tape 30 is attached to the side area of ​​the battery cell 20. Figure 8 As shown in (b). Then Figure 8 As shown in (c) to (e), the battery cell 20 on the adhesive laminating station 310 is flipped over and the above process is repeated to laminarize the other side of the battery cell 20. During the laminating process, the battery cell 20 is only subjected to pressure from the adhesive absorbing plate 230, and this pressure can be controlled within a relatively small range, thus effectively preventing damage to the battery cell 20.

[0076] In this embodiment, the glue absorbing plate 230 can be raised and lowered relative to the first side pressure member 221 and the second side pressure member 222. Furthermore, the raising and lowering direction of the glue absorbing plate 230 is consistent with the direction in which the first lifting mechanism 240 drives the support frame 210 to rise and fall, which is generally a vertical direction. Specifically, the first side pressure member 221 and the second side pressure member 222 can remain fixed relative to the support frame 210 in the vertical direction, while the glue absorbing plate 230 can be raised and lowered relative to the support frame 210 in the vertical direction. Alternatively, the glue absorbing plate 230 can remain fixed relative to the support frame 210 in the vertical direction, while the first side pressure member 221 and the second side pressure member 222 can be raised and lowered relative to the support frame 210 in the vertical direction.

[0077] When the tape laminating device 200 is not activated for laminating, the adhesive absorbing plate 230 extends from between the first and second side pressure members 221, 222 or is flush with the lower edges of these members. This facilitates the adhesive absorbing plate 230 to absorb the adhesive tape 30. Furthermore, when the first lifting mechanism 240 drives the support frame 210 downward to laminating, the adhesive tape 30 absorbed by the adhesive absorbing plate 230 first contacts the large surface area of ​​the battery cell 20 and is pressed against this large surface area. Subsequently, the adhesive absorbing plate 230 maintains contact with this large surface area while the first and second side pressure members 221, 222 descend relative to the adhesive absorbing plate 230, thereby pressing down the portion of the adhesive tape 30 extending beyond the edge of the battery cell 20. This allows the adhesive tape 30 to adhere to the large surface area and then the side areas of the battery cell 20, effectively stretching the adhesive tape 30 and preventing wrinkles.

[0078] Specifically, in this embodiment, the first side pressure member 221 and the second side pressure member 222 are both configured as elongated plates and extend along the edge of the adhesive suction plate 230. The first side pressure member 221 and the second side pressure member 222 can be in the shape of a rod or a strip, thereby providing a larger contact area with the adhesive tape 30. When the portion of the adhesive tape 30 extending beyond the edge of the battery cell 20 is pressed downward, the adhesive tape 30 can be effectively unfolded, thereby further preventing wrinkles in the adhesive tape 30.

[0079] In this embodiment, the adhesive absorbing plate 230 can slide relative to the support frame 210 . The tape applying device 200 further includes a buffer assembly 250 . The buffer assembly 250 is disposed between the support frame 210 and the adhesive absorbing plate 230 .

[0080] Specifically, the adhesive absorbing plate 230 can be slidably mounted on the support frame 210 or on the large plate 260. The buffer assembly 250 can be a buffer cylinder, a gas spring, or a metal spring, as long as it can elastically deform under external force. When the buffer assembly 250 is a buffer cylinder, the buffer cylinder is fixed to the support frame 210, and its piston rod is connected to the adhesive absorbing plate 230.

[0081] More specifically, under the action of the buffer assembly 250, the glue absorbing plate 230 extends from between the first side pressure member 221 and the second side pressure member 222 or is flush with the first side pressure member 221 and the second side pressure member 222, and the glue absorbing plate 230 can overcome the force of the buffer assembly 250 and retract relative to the first side pressure member 221 and the second side pressure member 222.

[0082] As the first lifting mechanism 240 drives the support frame 210, which in turn moves the adhesive absorbing plate 230 and the side pressure mechanism 220 toward the adhesive laminating platform 310, the adhesive absorbing plate 230 initially presses the adhesive tape 30 against the large surface area of ​​the battery cell 20. Then, as the first lifting mechanism 240 continues to drive the support frame 210, the adhesive absorbing plate 230 overcomes the force of the buffer assembly 250 and retracts relative to the first and second side pressure members 221, 222, thereby maintaining contact with the large surface area of ​​the battery cell 20. The first and second side pressure members 221, 222 continue to descend, thereby pressing down the portion of the adhesive tape 30 extending beyond the edge of the battery cell 20. In other words, the first and second side pressure members 221, 222 are fixedly mounted to the support frame 210 in a vertical direction relative to the support frame 210, thereby simplifying the structure of the tape laminating device 200.

[0083] Moreover, the buffer component 250 can also play a buffering role at the moment when the glue absorbing plate 230 contacts the battery cell 20, thereby avoiding hard contact between the glue absorbing plate 230 and the battery cell 20, and further preventing damage to the battery cell 20 during the glue application process.

[0084] It should be pointed out that in other embodiments, the first side pressure member 221 and the second side pressure member 222 can also be installed on the support frame 210 in a liftable manner; after the glue suction plate 230 presses the tape 30 on a large surface area of ​​the battery cell 20, the first lifting mechanism 240 stops driving the support frame 210, and the first side pressure member 221 and the second side pressure member 222 descend relative to the support frame 210, thereby pressing down the portion of the tape 30 extending out of the edge of the battery cell 20.

[0085] Furthermore, in this embodiment, the tape applying device 200 further includes a support member 270 . The support member 270 is capable of sliding relative to the support frame 210 , and the adhesive absorbing plate 230 is fixed to the support member 270 .

[0086] Specifically, the support member 270 can be a cantilevered structure. The support member 270 can be mounted on the support frame 210 via a guide rail and a slider, or it can be mounted on the large plate 260. In this way, the glue absorbing plate 230 can slide relative to the support frame 210. The support member 270 can provide good support for the glue absorbing plate 230, facilitating its installation. More specifically, the buffer assembly 250 is connected to the glue absorbing plate 230 via the support member.

[0087] The battery cell 20 is placed on the gluing table 310, with one side obscured by the table 310. The tape applying device 200 can retrieve one tape 30 at a time and apply the tape 30 to the upward-facing side of the battery cell 20. Therefore, after gluing the upward-facing side of the battery cell 20 on the gluing table 310, the battery cell 20 needs to be turned over so that the side originally obscured by the table 310 faces upward.

[0088] Please also refer to Figure 5 、 Figure 6 and Figure 7 In this embodiment, the glue support device 300 further includes a flipping mechanism 320, which is capable of flipping the battery cell 20 supported on the glue laminating platform 310 to facilitate the tape laminating device 200 to apply glue to both sides of the battery cell 20. The flipping mechanism 320 includes a clamping claw 321, which is disposed at the rotating end of the flipping mechanism 320. When the battery cell 20 needs to be flipped, the clamping claw 321 first clamps the battery cell 20 on the glue laminating platform 310, and then the flipping mechanism 320 drives the clamping claw 321 to rotate 180 degrees, and finally the battery cell 20 is placed back on the glue laminating platform 310. The flipping mechanism 320 can use a motor, a rotary cylinder, or the like to drive the clamping claw 321 to rotate.

[0089] Furthermore, in this embodiment, the glue laminating support device 300 further includes a third lifting mechanism 330 , and the third lifting mechanism 330 is connected to at least one of the glue laminating platform 310 and the turning mechanism 320 .

[0090] The third lifting mechanism 330 can be driven by a pneumatic cylinder, an electric cylinder, or a motor screw pair. Driven by the third lifting mechanism 330, the gluing platform 310 and the flipping mechanism 320 can be raised and lowered relative to each other. After the clamping claws 321 clamp the battery cell 20, the third lifting mechanism 330 can drive the gluing platform 310 and the flipping mechanism 320 away from each other to separate the battery cell 20 from the gluing platform 310. In this way, the flipping mechanism 320 can avoid interference with the gluing platform 310 during the process of driving the battery cell 20 to flip over. After the battery cell 20 is flipped over, the third lifting mechanism 330 drives the gluing platform 310 and the flipping mechanism 320 closer together until the battery cell 20 is once again supported on the gluing platform 310.

[0091] Specifically, the third lifting mechanism 330 can be connected to the gluing platform 310, the flipping mechanism 320, or both. When the third lifting mechanism 330 is connected to both the gluing platform 310 and the flipping mechanism 320, it can drive the gluing platform 310 and the flipping mechanism 320 to move toward or away from each other. Furthermore, the third lifting mechanism 330 can use two separate drivers to drive the gluing platform 310 and the flipping mechanism 320, or a single driver to drive both simultaneously.

[0092] The flipping mechanism 320 is positioned near the gluing platform 310, located on at least one side of the platform 310. Specifically, in this embodiment, a flipping mechanism 320 is positioned on both sides of the gluing platform 310 in the longitudinal direction. Thus, when flipping the battery cell 20, the grippers 321 of the flipping mechanisms 320 on either side of the gluing platform 310 can grip the battery cell 20 along its longitudinal ends. This stabilizes the battery cell 20 during flipping and effectively prevents it from tilting or loosening.

[0093] Furthermore, in this embodiment, the third lifting mechanism 330 is connected to the gluing platform 310. This means that after the clamping jaws 321 grip the battery cell 20, they can initially remain stationary. The third lifting mechanism 330 then drives the gluing platform 310 downward to separate the battery cell 20 from the gluing platform 310. This allows the flipping mechanism 320 to maintain its position, eliminating the need for the battery cell 20 to be lifted or lowered before flipping. This prevents the lifting action from causing the battery cell 20 to shake, thereby reducing the likelihood of the battery cell 20 tilting or loosening during the flipping process and further improving the stability of the battery cell 20.

[0094] When gripping the battery cell 20, the clamping jaws 321 typically grip the battery cell 20 from the side. This can easily cause the battery cell 20 to break apart, or even completely destroy it. To address this issue, in this embodiment, a retaining groove 311 is formed on the supporting surface of the adhesive laminating platform 310.

[0095] The relief groove 311 is generally elongated, with at least one end extending to the side of the adhesive laminating platform 310. The relief groove 311 allows the clamping jaws 321 to extend into the gap. When gripping the battery cell 20, the clamping jaws 321 extend through the relief groove 311 to the bottom of the battery cell 20, then clamp the battery cell 20 along its upper and lower sides. In other words, the clamping jaws 321 can reliably clamp the battery cell 20 along its thickness, thereby minimizing damage to the battery cell 20 and effectively preventing the battery cell 20 from being loosened.

[0096] Furthermore, in this embodiment, the avoidance groove 311 includes a first groove 3111 extending along the width direction of the glue laminating platform 310 and a second groove 3112 extending along the length direction of the glue laminating platform 310 .

[0097] The second groove 3112 allows the grippers 321 to extend into the second groove, facilitating the flipping mechanisms 120 on either side of the gluing platform 310 to grip the battery cell 20 along its length. Furthermore, the battery cell 20 is typically transported to the gluing platform 310 by a loading robot (not shown), which typically grips the battery cell 20 along its width. Therefore, the first groove 3111 provides a safe position for the loading robot, facilitating its smooth placement of the battery cell 20 onto the gluing platform 310.

[0098] Of course, in other embodiments, the loading clamp and the clamp 321 may also share the first groove 3111 or the second groove 3112. Then, the avoidance groove 311 may only include the first groove 3111 extending along the width direction of the glue laminating platform 310, or the second groove 3112 extending along the length direction of the glue laminating platform 310.

[0099] Because the gluing platform 310 has multiple relief grooves 311 formed on its support surface, the support surface is not completely flat. An uneven support surface can easily result in uneven force on the bottom of the battery cell 20. Consequently, the pressure applied during the gluing process could cause indentations on the surface of the battery cell 20 or even damage the cell 20.

[0100] To avoid this phenomenon, in this embodiment, the glue support device 300 also includes a filling mechanism 340, which includes a filling plate 341 and a filling drive 342. The filling plate 341 is accommodated in the avoidance groove 311 and connected to the filling drive 342.

[0101] The filling plate 341 is arranged in a one-to-one correspondence with the avoidance groove 311, and its shape matches the shape of the avoidance groove 311. Specifically in the present embodiment, the filling plate 341 includes a first filling portion and a second filling portion, and the first filling portion and the second filling portion are respectively accommodated in the first groove 3111 and the second groove 3112. The filling drive 342 can drive the filling plate 341 to rise and fall relative to the avoidance groove 311. Specifically, the filling drive 342 can drive the filling plate 341 to descend until the filling plate 341 is exposed from the avoidance groove 311; the filling drive 342 can drive the filling plate 341 to rise until the filling plate 341 is flush with the bearing surface of the glue laminating table 310.

[0102] During the normal gluing process, the aligning plate 341, driven by the aligning driver 342, is aligned with the supporting surface of the gluing platform 310, thereby aligning the avoidance groove 311. This creates a completely flat surface on the supporting surface of the gluing platform 310, thus preventing indentations on the surface of the battery cell 20. To flip the battery cell 20, the aligning driver 342 lowers the aligning plate 341 to expose the avoidance groove 311. This allows the clamping jaws 321 to extend beneath the battery cell 20 supported on the gluing platform 310 and clamp the cell 20 from both sides.

[0103] Also, please refer again to Figure 5 In this embodiment, the adhesive support device 300 further includes a pressing mechanism 350 . The pressing mechanism 350 includes a pressing member 351 and a pressing drive assembly 352 . The pressing drive assembly 352 is connected to the pressing member 351 .

[0104] After the battery cell 20 to be glued is transferred to the gluing platform 310, the pressing member 351, driven by the pressing drive assembly 352, presses the battery cell 20 against the gluing platform 310, effectively preventing the battery cell 20 from tilting or loosening. During the gluing process, the pressing member 351, driven by the pressing drive assembly 352, forms a safe position for the battery cell 20.

[0105] Specifically, the pressing drive assembly 352 can drive the holding member 351 to move in a direction parallel to the supporting surface of the gluing platform 310 and in a direction perpendicular to the supporting surface of the gluing platform 310. When the pressing drive assembly 352 drives the holding member 351 in a direction parallel to the supporting surface of the gluing platform 310, the holding member 351 can be moved above the gluing platform 310 or out of the range of the gluing platform 310; when the pressing drive assembly 352 drives the holding member 351 in a direction perpendicular to the supporting surface of the gluing platform 310, the holding member 351 can be moved closer to or away from the battery cell 20 on the gluing platform 310.

[0106] The holding members 351 are generally distributed on both sides of the gluing platform 310 in the width direction to avoid interference with the flipping mechanism 320. In addition, each side of the gluing platform 310 is provided with multiple holding members 351 spaced along the edge, and the multiple holding members 351 can better press the battery cells 20.

[0107] Furthermore, in this embodiment, the glue laminating support device 300 further includes a lifting platform 360 . The glue laminating platform 310 and the pressing mechanism 350 are both disposed on the lifting platform 360 . The lifting platform 360 is connected to the third lifting mechanism 330 .

[0108] The third lifting mechanism 330 drives the lifting platform 360 up and down, thereby simultaneously raising and lowering the gluing platform 310 and the pressing mechanism 350. Because both the gluing platform 310 and the pressing mechanism 350 are mounted on the lifting platform 360, they can maintain their relative positions after multiple lifts, ensuring that the pressing member 351 can smoothly press the battery cells 20 on the gluing platform 310.

[0109] In the solid-state battery gluing device 10, the battery cell 20 to be glued is placed on the gluing platform 310. The glue absorbing plate 230 first absorbs the adhesive tape 30 provided by the glue preparation device 100. The first lifting mechanism 240 then drives the support frame 210 to drive the glue absorbing plate 230 and the side pressure mechanism 220 to move toward the battery cell 20 to be glued until the glue absorbing plate 230 presses the absorbed adhesive tape 30 against the large surface area of ​​the battery cell 20. The glue absorbing plate 230 maintains contact with the large surface area of ​​the battery cell 20, and the first side pressure member 221 and the second side pressure member 222 can press down the portion of the adhesive tape 30 that extends beyond the edge of the battery cell 20. The side pressure driving member 223 then drives the first side pressure member 221 and the second side pressure member 222 toward each other, so that the adhesive tape 30 can be attached to the side area of ​​the battery cell 20. Next, the battery cell 20 on the gluing platform 310 is turned over, and the above process is repeated to glue the other side of the battery cell 20. The solid-state battery gluing device 10 applies relatively little pressure to the battery cell 20 during the gluing process, thus effectively preventing damage to the battery cell 20 .

In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described.

It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
