[0002] In the field of battery cell gluing, the traditional solution is generally: the gluing mechanism pulls the tape to a preset length, the gluing mechanism and the gluing mechanism respectively clamp the two ends of the tape of preset length, the gluing mechanism cuts the tape pulled by the gluing mechanism, the adsorption plate moves to the tape pulled by the gluing mechanism, and adsorbs the cut tape to the battery cell, thereby adhering the tape to the battery cell; and when the adsorption plate adsorbs the tape to the battery cell, it needs to rotate relative to the outer periphery of the battery cell to ensure that the tape is completely adhered to the battery cell.

DETAILED DESCRIPTION

[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0031] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0032] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0033] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0034] See also Figure 1 , the battery cell gluing device provided in the embodiment of the present application is now described. The battery cell gluing device includes a glue feeding mechanism 100, a first glue pressing mechanism 200, a glue cutting mechanism 300 and a second glue pressing mechanism 400. The glue feeding mechanism 100 can allow part of the tape m to extend out of the glue feeding mechanism 100, and is used to clamp the tape m to one side of the battery cell n; the first glue pressing mechanism 200 is used to squeeze the first preset position of the battery cell n, so that the head end of the tape m located on one side of the battery cell n is elastically pressed against the battery cell n; the battery cell n is wound for the first time after the glue feeding mechanism 100 releases the tape m; the glue cutting mechanism 300 is used to cut the tape m when the battery cell n completes the first winding, and the battery cell n can be wound for the second time after the glue cutting mechanism 300 cuts the tape m; the second glue pressing mechanism 400 is used to squeeze the second preset position of the battery cell n, so that when the battery cell n is wound for the second time, the tail end of the cut tape m is elastically pressed against the battery cell n.

[0035] It should be noted that the glue feeding mechanism 100 can allow part of the tape m to extend out of the glue feeding mechanism 100. Based on this, the tape m can be pulled manually or by a robot to allow part of the tape m to extend out of the glue feeding mechanism 100; and, when the battery cell n is wound for the first time, the tape m can extend out of the glue feeding mechanism 100 under the traction of the battery cell n. At this time, the glue feeding mechanism 100 can be reset, so that when the battery cell n completes the first winding and the glue cutting mechanism 300 cuts off the tape m, part of the tape m can still be exposed outside the glue feeding mechanism 100.

[0036] It should also be noted that the second preset position can be the end of the pole piece of the battery cell n. Before the battery cell n is wound, the second glue pressing mechanism 400 squeezes the end of the pole piece of the battery cell n to prevent the end of the pole piece of the battery cell n from loosening. On the one hand, it enables the tape m to be better wound around the periphery of the battery cell n. On the other hand, it helps to improve the quality of the battery cell n after winding.

[0037] In addition, the first glue pressing mechanism 200 elastically presses the head end of the tape m against the battery cell n, which means that the pressure exerted by the first glue pressing mechanism 200 on the battery cell n is elastic pressure, and the pressure can be adjusted elastically and automatically, so that the pressure of the first glue pressing mechanism 200 on the battery cell n is appropriate, which can not only firmly stick the tape m to the battery cell n, but also will not damage the battery cell n.

[0038] Similarly, the second glue pressing mechanism 400 elastically presses the tail end of the adhesive tape m against the battery cell n. The pressure is also elastic and will not damage the battery cell n.

[0039] Based on this, the working principle of the battery cell gluing device is as follows: the tape m is pulled manually or by a robot, so that part of the tape m extends out of the glue feeding mechanism 100, and the glue feeding mechanism 100 clamps the tape m extending out of the glue feeding mechanism 100 to one side of the battery cell n; the first glue pressing mechanism 200 elastically presses the head end of the tape m extending out of the glue feeding mechanism 100 against the first preset position of the battery cell n, and the second glue pressing mechanism 400 elastically presses against the second preset position of the battery cell n; then, the battery cell n undergoes the first winding and gluing, at which time the glue feeding mechanism 100 is reset; then, the glue cutting mechanism 300 cuts off the tape m, so that part of the tape m still remains outside the glue feeding mechanism 100; then, the battery cell n undergoes the second winding and gluing, until the tail end of the cut tape m is wound by the battery cell n to the second glue pressing mechanism 400, and is pressed on the battery cell n by the second glue pressing mechanism 400, completing the winding work of one battery cell n. Among them, since part of the tape m still extends out of the glue feeding mechanism 100 after the glue cutting mechanism 300 cuts off the tape m, the glue feeding mechanism 100 can clamp the tape m extending out of the glue feeding mechanism 100 and send it to one side of the next battery cell n to be attached to the next battery cell n... and so on, the continuous gluing work of multiple battery cells n is realized in sequence.

[0040] When the battery cell n is wound for the first time, the first glue pressing mechanism 200 can be reset to be away from the battery cell n.

[0041] In the battery cell gluing device in the embodiment of the present application, when gluing, part of the tape m is first extended out of the glue feeding mechanism 100, and the glue feeding mechanism 100 clamps the tape m extended out of the glue feeding mechanism 100 to one side of the battery cell n; then, the first glue pressing mechanism 200 elastically presses the head end of the tape m clamped to one side of the battery cell n against a first preset position of the battery cell n, at this time, the glue clamping mechanism releases the tape m, and the battery cell n is wound for the first time; then, the glue cutting mechanism 300 cuts the tape m, and the battery cell n is wound for the second time, until the tail end of the cut tape m is elastically pressed against the battery cell n by the second glue pressing mechanism 400, and the gluing work of the battery cell n is completed; in this way, through the arrangement of the glue feeding mechanism 100, the first glue pressing mechanism 200, the glue cutting mechanism 300 and the second glue pressing mechanism 400, the gluing steps of the battery cell n are reduced, the gluing operation of the battery cell n is simplified, and the time consumption of gluing is reduced, which helps to improve the efficiency of gluing the battery cell n. In addition, since the first glue pressing mechanism 200 and the second glue pressing mechanism 400 are elastically pressed against the first preset position and the second preset position of the battery cell n respectively, the battery cell n can be protected to avoid being crushed.

[0042] In one embodiment, see Figure 2 and Figure 3 The first glue pressing mechanism 200 includes a first driver 210, a first transfer seat 220 that can be driven by the first driver 210 to move linearly, a first pressure wheel seat 230 slidably connected to the first transfer seat 220, and a first pressure wheel 240 rotatably arranged on the first pressure wheel seat 230, a first elastic member 250 is abutted between the first pressure wheel seat 230 and the first transfer seat 220, and the first pressure wheel 240 is used to press on the first preset position of the battery cell n.

[0043] The first driver 210 is used to output linear motion, the first transfer seat 220 is connected to the output end of the first driver 210, and the first transfer seat 220 can be driven by the first driver 210 to move linearly. The first pressure wheel seat 230, the first elastic member 250 and the first pressure wheel 240 are all installed on the first transfer seat 220, so that they can move linearly with the first transfer seat 220.

[0044] After the adhesive feeding mechanism 100 transfers the adhesive tape m to one side of the battery cell n, the first transfer seat 220 moves toward the battery cell n by a first preset distance, and the first pressure wheel 240 elastically presses the head end of the adhesive tape m to the first preset position of the battery cell n under the action of the first elastic member 250. At the same time, since the first pressure wheel 240 is rotatably arranged on the first pressure wheel seat 230, when the battery cell n is first wound, the first pressure wheel 240 and the battery cell n can rotate outward at the same time, which helps to prevent the first pressure wheel 240 from interfering with the winding work of the battery cell n, and has a guiding effect on the adhesive tape m, so that the adhesive tape m can be pressed flatly on the battery cell n. In addition, due to the setting of the first elastic member 250, the first pressure wheel 240 can be elastically pressed on the battery cell n, reducing the damage of the first pressure wheel 240 to the battery cell n.

[0045] In one embodiment, the central axis of the first pressing wheel 240 is arranged to be parallel to the central axis of the battery cell n. In this way, when the battery cell n is wound, the battery cell n and the first pressing wheel 240 can rotate outward at the same time to protect the battery cell n.

[0046] In one embodiment, see Figure 2 The first glue pressing mechanism 200 further includes a first guide member 260, one end of which is fixed to the first pressing wheel seat 230, and the other end of which is slidably connected to the first transfer seat 220. The first elastic member 250 is sleeved on the first guide member 260 and abuts between the first pressing wheel seat 230 and the first transfer seat 220. The first guide member 260 can not only form a sliding connection between the first pressing wheel seat 230 and the first transfer seat 220, but also guide the expansion and contraction of the first elastic member 250 to ensure that the first pressing wheel 240 can be stably pressed on the battery cell n. It can be understood that in other embodiments of the present application, one end of the first guide member 260 can be fixedly connected to the first transfer seat 220, and the other end of the first guide member 260 can be slidably connected to the first pressure wheel seat 230; or, the first pressure wheel seat 230 can be directly slidably set on the first transfer seat 220 without setting the first guide member 260 in the middle; or, the first elastic member 250 can be abutted between the first transfer seat 220 and the output end of the first driver 210, which is not a sole limitation here.

[0047] In one embodiment, the expansion and contraction direction of the first elastic member 250 is perpendicular to the central axis direction of the first pressing wheel 240 , so that the first pressing wheel 240 can be stably pressed onto the battery cell n.

[0048] Optionally, the first elastic member 250 is a cylindrical spring, the first guide member 260 is a cylindrical rod-shaped structure, and the first elastic member 250 is sleeved on the first guide member 260. It can be understood that in other embodiments of the present application, the first elastic member 250 can also be a spring or other elastic structure, and a hole can be opened in the first guide member 260 to accommodate the first elastic member 250 in the hole and abut between the first pressure wheel seat 230 and the first transfer seat.

[0049] In one embodiment, see Figure 2 The first guide member 260 can be fixedly connected to the first pressure roller seat 230 by screw locking. In other embodiments, the first guide member 260 can also be fixed to the first pressure roller seat 230 by welding, bonding, integral connection or buckling.

[0050] In one embodiment, see Figure 2 A first guide hole (not shown) is formed on the first transfer seat 220, and the first guide member 260 slides through the first guide hole. A limit plate 270 is fixedly installed on one end of the first guide member 260 away from the first pressure wheel seat 230. The limit plate 270 can be stopped at the side of the first transfer seat 220 away from the first guide member 260. The limit plate 270 can prevent the first guide member 260 from sliding off the first transfer seat 220.

[0051] Optionally, the first driver 210 may be a driving device such as a linear motor, a cylinder, an electric cylinder, a motor and a screw mechanism.

[0052] In one embodiment, see Figure 1 The battery cell gluing device further includes a substrate 700, the first driver 210 is mounted on the substrate 700, and the first transfer seat 220 is slidably disposed on the substrate 700. Specifically, a guide rail structure is disposed on the substrate 700, and the guide rail structure is used to guide the linear sliding of the first transfer seat 220 to ensure that the first transfer seat 220 moves smoothly on the substrate 700.

[0053] In one embodiment, see Figure 2 and Figure 3 The rubber cutting mechanism 300 includes a cutter driver 310 mounted on the first transfer seat 220 , a cutter seat 320 that can be driven by the cutter driver 310 to move linearly, and a cutter 330 mounted on the cutter seat 320 .

[0054] In this embodiment, the cutter driver 310 is installed on the first transfer seat 220, so that when the first driver 210 is started, the first transfer seat 220 can drive the first pressure wheel 240, the first transfer seat 220, the cutter driver 310 and the cutter 330 to move together under the drive of the first driver 210, so that when the first pressure wheel 240 is moved to the first preset position of the battery cell n under the drive of the first transfer seat 220, the cutter 330 can be moved to the first preset position of the battery cell n under the drive of the first transfer seat 220 at the same time. The first pressing wheel 240 is placed on the side of the core n, so that the cutter 330 can quickly cut the glue in the subsequent operation, so that the first glue pressing mechanism 200 and the glue cutting mechanism 300 have better action continuity, which helps to improve the glue pasting efficiency of the battery cell n; when the first pressing wheel 240 is reset under the drive of the first transfer seat 220, the cutter 330 can also be reset at the same time under the drive of the first transfer seat 220, which is conducive to improving the working coordination and continuity of the first glue pressing mechanism 200 and the glue cutting mechanism 300, thereby helping to improve the glue pasting efficiency of the battery cell n. In addition, installing the glue cutting mechanism 300 on the first glue pressing mechanism 200 helps to compress the space of the battery cell glue pasting device, helps to reduce the volume of the battery cell glue pasting device, and thus helps to improve the layout flexibility of the battery cell glue pasting device. It is understandable that in other embodiments of the present application, the above-mentioned cutter driver 310 may not be installed on the first transfer seat 220, but the cutter driver 310 may be directly installed on the substrate 700, and the cutter seat 320 may be slidably disposed on the substrate 700, which is not a sole limitation here.

[0055] In one embodiment, see Figure 3 A guide rod 340 is connected between the cutter seat 320 and the first transfer seat 220 , one end of the guide rod 340 is fixedly connected to the cutter seat 320 , and the other end of the guide rod 340 is slidably inserted into the first transfer seat 220 , so that the linear movement of the cutter seat 320 can be guided by the guide rod 340 .

[0056] Optionally, the cutter driver 310 may be a driving device such as a linear motor, a cylinder, an electric cylinder, a motor and a screw mechanism.

[0057] In one embodiment, see Figure 4 The second glue pressing mechanism 400 includes a second driver 410, a second transfer seat 420 that can be driven by the second driver 410 to move linearly, a second pressure wheel seat 430 installed on the second transfer seat 420, and a second pressure wheel 440 rotatably arranged on the second pressure wheel seat 430. A second elastic member 450 is abutted between the output end of the second driver 410 and the second transfer seat 420. The second pressure wheel 440 is used to press on the second preset position of the battery cell n.

[0058] The second driver 410 is used to output linear motion, and the second transfer seat 420 is connected to the output end of the second driver 410 through the second elastic member 450, and the second transfer seat 420 can be driven by the second driver 410 to move linearly. The second pressure wheel seat 430 and the second pressure wheel 440 are both installed on the second transfer seat 420, so that they can move linearly with the second transfer seat 420. Under the action of the second elastic member 450, the second pressure wheel 440 elastically presses the tail end of the tape m to the second preset position of the battery cell n. At the same time, since the second pressure wheel 440 is rotatably arranged on the second pressure wheel seat 430, when the battery cell n is wound for the second time, the second pressure wheel 440 and the battery cell n can rotate outward at the same time, which helps to prevent the second pressure wheel 440 from interfering with the winding work of the battery cell n, and has a guiding effect on the tape m, so that the tape m can be pressed flat on the battery cell n. In addition, due to the provision of the second elastic member 450 , the second pressing wheel 440 can be elastically pressed on the battery cell n, thereby reducing damage to the battery cell n caused by the second pressing wheel 440 .

[0059] In one embodiment, the central axis of the second pressing wheel 440 is arranged to be parallel to the central axis of the battery cell n. In this way, when the battery cell n is wound, the battery cell n and the second pressing wheel 440 can rotate outward at the same time to protect the battery cell n.

[0060] In one embodiment, see Figure 4 The second glue pressing mechanism 400 further includes a second guide member 460, one end of which is fixed to the output end of the second driver 410, and the other end of which is slidably connected to the second transfer seat 420. The second elastic member 450 is sleeved on the second guide member 460 and abuts between the output end of the second driver 410 and the second transfer seat 420. The second guide member 460 is not only configured to form a sliding connection between the second driver 410 and the second transfer seat 420, but also to guide the expansion and contraction of the second elastic member 450, so as to ensure that the second pressing wheel 440 can be stably pressed on the battery cell n. It can be understood that in other embodiments of the present application, one end of the second guide member 460 can be fixedly connected to the second transfer seat 420, and the other end of the second guide member 460 can be slidably connected to the output end of the second driver 410; or, the output end of the second driver 410 can be directly slidably connected to the second transfer seat 420 without the second guide member 460 in the middle; or, the second elastic member 450 can be abutted between the second transfer seat 420 and the second pressure wheel seat 430, which is not a sole limitation here.

Among them, the first glue clamping component 130 and the second glue clamping component 140 respectively clamp different positions of the adhesive tape m, and jointly transfer the adhesive tape m to one side of the battery cell n under the drive of the glue feeding plate 120, so that the adhesive tape m can be stably transported to one side of the battery cell n, which is beneficial to the positioning of the adhesive tape m, thereby facilitating the improvement of the adhesive bonding effect of the battery cell n.

[0068] In one embodiment, see Figure 5 The driving component 110 can output a linear motion in a first direction X and a linear motion in a second direction Y, wherein the first direction X and the second direction Y are both perpendicular to the axial direction of the battery cell n, and the first direction X and the second direction Y form an angle with each other. The driving component 110 can drive the first laminating component 130 and the second laminating component 140 to move along the first direction X and / or the second direction Y through the glue feeding plate 120, so as to better adjust the position of the adhesive tape m, so that the adhesive tape m extends to one side of the battery cell n, so that the first glue pressing mechanism 200 presses the adhesive tape m located on one side of the battery cell n at the first preset position of the battery cell n, thereby helping to ensure the gluing effect of the battery cell n.

[0069] Preferably, the first direction X and the second direction Y are perpendicular to each other, the first direction X is parallel to the length extension direction of the glue feeding plate 120 , and the first laminated component 130 and the second laminated component 140 are spaced apart along the first direction X.

[0070] In one embodiment, see Figure 6The driving assembly 110 includes a third driver 111, a third transfer seat 112 and a fourth driver 113. The third driver 111 is used to output a linear motion along the first direction X. The third transfer seat 112 is connected to the output end of the third driver 111. The fourth driver 113 is installed on the third transfer seat 112. The fourth driver 113 is used to output a linear motion along the second direction Y. The glue feeding plate 120 is installed at the output end of the fourth driver 113. Specifically, the third driver 111 can drive the third transfer seat 112, the fourth driver 113, the glue feeding plate 120, the first glue clamping assembly 130 and the second glue clamping assembly 140 to move along the first direction X. The fourth driver 113 can drive the glue feeding plate 120, the first glue clamping assembly 130 and the second glue clamping assembly 140 to move along the second direction Y, so as to realize the precise delivery of the adhesive tape m.

[0071] Optionally, the third driver 111 may be a linear motor, a pneumatic cylinder, an electric cylinder, a motor with a screw mechanism, etc. The fourth driver 113 may be a linear motor, a pneumatic cylinder, an electric cylinder, a motor with a screw mechanism, etc.

[0072] Optionally, see Figure 6 The glue feeding mechanism 100 further includes a second base 150, the second base 150 is mounted on the substrate 700, the third driver 111 is mounted on the second base 150, and the third transfer seat 112 is linearly slidably disposed on the second base 150 via a guide rail. It can be understood that in other embodiments, the third driver 111 and the third transfer seat 112 can also be directly disposed on the substrate 700, which is not limited here.

[0073] In one embodiment, see Figures 5 to 7 The first glue clamping assembly 130 includes a first glue guide wheel 132 rotatably disposed on the glue feeding plate 120 and a glue clamping driver 131 disposed on the glue feeding plate 120 . The glue clamping driver 131 is used to cooperate with the first glue guide wheel 132 to clamp or release the adhesive tape m. Such a configuration enables the output end of the glue clamping driver 131 to cooperate with the first rubber guide wheel 132 to clamp the adhesive tape m or release the adhesive tape m, and the first rubber guide wheel 132 can rotate on the adhesive feeding plate 120. When the glue clamping driver 131 cooperates with the first rubber guide wheel 132 to clamp the adhesive tape m, the first rubber guide wheel 132 can be rotated and adjusted accordingly, which is conducive to ensuring the clamping effect of the adhesive tape m. On the other hand, when the battery cell n is wound for the first time to pull the adhesive tape m, the glue clamping driver 131 releases the first rubber guide wheel 132, so that the adhesive tape m can drive the first rubber guide wheel 132 to rotate when being pulled. In this way, by judging whether the first rubber guide wheel 132 is rotating, the situation of the adhesive tape m can be obtained, which is helpful to improve the effect of gluing the battery cell n. Among them, when the battery cell n is wound for the first time, the first rubber guide wheel 132 does not rotate, which can indicate that the adhesive tape m has been used up or there are abnormal situations such as the adhesive tape m being stuck or offset.

[0074] In one embodiment, please refer to Figure 5 , a plurality of detection blocks 133 are arranged on the first rubber guide wheel 132, and the plurality of detection blocks 133 are arranged at intervals and evenly on the outer peripheral wall of the first rubber guide wheel 132; a sensor 134 is arranged on the rubber feeding plate 120, and the sensor 134 is used to detect the detection block 133. Among them, when the detection block 133 rotates to the detection range of the sensor 134, the sensor 134 can detect the detection block 133. In this way, by determining whether the plurality of detection blocks 133 rotate to the detection range of the sensor 134 in sequence, it is possible to determine whether the first rubber guide wheel 132 rotates, thereby obtaining the specific use of the adhesive tape m, which helps to improve the effect of gluing the battery cell n.

[0075] In one embodiment, see Figure 7 The output end of the clamping driver 131 is provided with a pressing plate 135, which is used to cooperate with the first rubber guide wheel 132 to clamp or release the adhesive tape m under the drive of the clamping driver 131. Specifically, the clamping driver 131 is used to output a linear motion, and the linear motion direction is perpendicular to the axis direction of the first rubber guide wheel 132, so that the clamping effect of the clamping driver 131 and the first rubber guide wheel 132 on the adhesive tape m can be ensured. When the battery cell n is wound for the first time, the clamping driver 131 drives the pressing plate 135 to retreat linearly to release the adhesive tape m.

[0076] Optionally, the clamping driver 131 can be configured as a driving device such as a linear motor, a cylinder, an electric cylinder, a motor and a screw mechanism.

[0077] In one embodiment, see Figure 6 The outer wall of the first rubber guide wheel 132 is provided with a groove 1321; the groove 1321 can be set as an annular groove, and multiple annular grooves are distributed in the outer wall of the first rubber guide wheel 132 at intervals along the axial direction, or the groove 1321 is set as a spiral groove. Such a configuration helps to reduce the contact area between the adhesive tape m and the first rubber guide wheel 132, and prevent the adhesive surface of the adhesive tape m from being damaged by the first rubber guide wheel 132.

[0078] Optional, see Figure 6 A second rubber guide wheel 160 is also rotatably provided on the rubber feeding plate 120, and the second rubber guide wheel 160 is distributed on two opposite sides of the first rubber guide wheel 132 along the first direction X. The adhesive tape m can be positioned and guided by the first rubber guide wheel 132 and the second rubber guide wheel 160, so as to ensure the guiding and traction effect of the adhesive tape m.

[0079] In one embodiment, see Figures 5 to 7The second clamping assembly 140 includes a first clamping plate 141, a second clamping plate 142 and a clamping plate driver 143. The clamping plate driver 143 is used to drive the first clamping plate 141 and / or the second clamping plate 142 to move, so that the first clamping plate 141 and the second clamping plate 142 clamp or release the adhesive tape m. The clamping and release of the first clamping plate 141 and the second clamping plate 142 are controlled by the clamping plate driver 131. Compared with the elastic clamping method, the control method of the clamping plate driver 143 can ensure the clamping stability of the first clamping plate 141 and the second clamping plate 142, and prevent the adhesive tape m from retreating when the adhesive tape m is cut.

[0080] In one embodiment, see Figure 7 , the first clamping plate 141 is fixedly arranged on the glue feeding plate 120, the second clamping plate 142 is rotatably arranged on the glue feeding plate 120, the clamping plate driver 143 is installed on the glue feeding plate 120, the output end of the clamping plate driver 143 is connected to the second clamping plate 142, and the clamping plate driver 143 is used to drive the second clamping plate 142 to rotate on the glue feeding plate 120, so that the first clamping plate 141 and the second clamping plate 142 clamp or release the adhesive tape m. It can be understood that in other embodiments, the second clamping plate 142 can also be fixedly arranged on the glue feeding plate 120, and the clamping plate driver 143 can be used to drive the first clamping plate 141 to rotate on the glue feeding plate 120; or the clamping plate driver 143 can be used to simultaneously drive the first clamping plate 141 and the second clamping plate 142 to rotate; or the clamping plate driver 143 can be used to drive the first clamping plate 141 and the second clamping plate 142 to move relative to each other.

[0081] In one embodiment, see Figure 7 An extension portion 1411 extends from the top of the first clamping plate 141, and the extension portion 1411 is located above the second clamping plate 142. The extension portion 1411 is arranged opposite to the glue feeding plate 120. A rotating shaft 144 is connected between the extension portion 1411 and the glue feeding plate 120, and the second clamping plate 142 is rotatably arranged on the glue feeding plate 120 through the rotating shaft 144.

[0082] In one embodiment, see Figure 7 A connecting portion 1421 extends from the bottom of the second clamping plate 142, and the connecting portion 1421 is arranged away from the rotating shaft 144 of the second clamping plate 142. The clamping plate driver 143 is installed on the adhesive feeding plate 120, and the output end of the clamping plate driver 143 is connected to the connecting portion 1421. The clamping plate driver 143 is used to linearly push the connecting portion 1421 so that the second clamping plate 142 rotates around the rotating shaft 144 to clamp or release the adhesive tape m with the first clamping plate 141.

[0083] Optionally, the clamping plate driver 143 can be configured as a driving device such as a linear motor, a cylinder, an electric cylinder, a motor and a screw mechanism.

[0084] In one embodiment, see Figure 6 , the first clamping plate 141 and / or the second clamping plate 142 are provided with a blowing hole 1412 on the side where the adhesive tape m is exposed. The first clamping plate 141 is provided with a blowing hole 1412 on the side where the adhesive tape m is exposed, or the second clamping plate 142 is provided with a blowing hole 1412 on the side where the adhesive tape m is exposed, or both the first clamping plate 141 and the second clamping plate 142 are provided with a blowing hole 1412 on the side where the adhesive tape m is exposed; in this way, when the adhesive tape m extends out of the first clamping plate 141 and the second clamping plate 142, the external blowing device can blow air through the blowing hole 1412, thereby forming a layer of stable airflow beside the adhesive tape m extending out of the first clamping plate 141 and the second clamping plate 142, so as to ensure the posture flatness of the adhesive tape m extending out of the first clamping plate 141 and the second clamping plate 142, which is conducive to improving the quality of the adhesive tape m, thereby improving the gluing effect of the battery cell n.

[0085] Optionally, a plurality of blowing holes 1412 are distributed on the first clamping plate 141, and each blowing hole 1412 is evenly distributed along the height direction of the first clamping plate 141. The height direction of the first clamping plate 141 is also the axial direction of the battery cell n and the width direction of the tape m, so that the tape m can be ensured to have high flatness along the width direction.

[0086] Optional, such as Figure 1 and Figure 8 As shown, the battery cell glue sticking device also includes a glue supply tray 500 and a glue guiding mechanism 600 , wherein the glue supply tray 500 is used to provide the adhesive tape m, and the glue guiding mechanism 600 is used to guide the adhesive tape m wound on the glue supply tray 500 to the glue feeding mechanism 100 .

[0087] In one embodiment, see Figure 8The rubber guiding mechanism 600 includes a third base 650, a fourth transfer base 620, a third rubber guiding wheel 630, a fourth rubber guiding wheel 640 and a fifth driver 610. The fourth transfer base 620 is movably arranged on the third base 650, the third rubber guiding wheel 630 is arranged on the fourth transfer base 620, the fourth rubber guiding wheel 640 is arranged outside the fourth transfer base 620 and is relatively fixed to the third base 650; the fifth driver 610 is arranged on the third base 650, the fourth transfer base 620 is connected to the output end of the fifth driver 610, and can slide on the third base 650 under the drive of the fifth driver 610. Among them, the fourth rubber guiding wheel 640 can be set to at least two. During operation, the adhesive tape m on the adhesive supply tray 500 passes through the third adhesive guide wheel 630 and the fourth adhesive guide wheel 640, thereby extending to the adhesive feeding mechanism 100. The third adhesive guide wheel 630 and the fourth adhesive guide wheel 640 are arranged to guide the adhesive tape m, so that the adhesive tape m can extend to the adhesive feeding mechanism 100, which is beneficial for the adhesive tape m to be wound on the battery cell n; and the fourth transfer seat 620 can slide on the third base 650 under the drive of the fifth driver 610, so that the third adhesive guide wheel 630 moves relative to the third base 650, that is, the third adhesive guide wheel 630 moves relative to the fourth adhesive guide wheel 640, thereby realizing the pulling of the adhesive tape m. This helps to ensure the tension effect of the adhesive tape m on the basis of ensuring the guiding effect of the adhesive tape m, thereby facilitating the gluing effect of the battery cell n.

[0088] Optionally, the fifth driver 610 can be configured as a driving device such as a linear motor, a cylinder, an electric cylinder, a motor and a screw mechanism.

[0089] Based on the above concept, the working principle of the battery cell gluing device is as follows: first, a manual or mechanical hand pulls the adhesive tape m on the adhesive supply tray 500, so that the adhesive tape m passes through the adhesive guiding mechanism 600, the first adhesive clamping component 130 and the second adhesive clamping component 140 in sequence, so that part of the adhesive tape m extends out of the first clamping plate 141 and the second clamping plate 142 of the second adhesive clamping component 140, the adhesive clamping driver 131 and the first adhesive guide wheel 132 of the first adhesive clamping component 130 cooperate to clamp the adhesive tape m, and the first clamping plate 141 and the second clamping plate 142 of the second adhesive clamping component 140 clamp the adhesive tape m under the drive of the clamping plate driver 143, and at this time, the external blowing device blows air through the blowing hole 1412 to ensure the flatness of the adhesive tape m; then, the adhesive feeding plate 120 moves along the first direction X and / or the second direction Y under the drive of the driving component 110, thereby realizing the movement of the first adhesive clamping component 130 and the second adhesive clamping component 140 at the same time, so that the adhesive tape m extending out of the first clamping plate 141 and the second clamping plate 142 The tape m moves to one side of the battery cell n; then, the cutter seat 320 moves the first pressing wheel 240 and the cutter 330 under the drive of the cutter driver 310, so that the first pressing wheel 240 presses the head end of the tape m extending out of the first clamping plate 141 and the second clamping plate 142 to the first preset position of the battery cell n, and the second pressing wheel 440 presses the second preset position of the battery cell n under the transfer of the second transfer seat 420; the first rubber guide wheel 132 of the first rubber sandwich assembly 130 and the rubber sandwich driver 131 are loosened. The adhesive tape m is opened, and the battery cell n is wound and glued for the first time. At this time, the adhesive feeding plate 120 drives the first adhesive sandwich component 130 and the second adhesive sandwich component 140 to reset and move under the drive of the driving component 110, and then the cutter 330 moves under the drive of the cutter driver 310 to cut the adhesive tape m; then, the battery cell n is wound and glued for the second time, so that the tail end of the cut adhesive tape m is wound to the second pressing wheel 440, and the second pressing wheel 440 presses the tail end of the cut adhesive tape m on the battery cell n. Continuing, after the battery cell n completes the second winding and gluing, the first adhesive sandwich component 130 and the second adhesive sandwich component 140 clamp the adhesive tape m, and the adhesive feeding plate 120, driven by the driving component 110, moves the adhesive tape m extending out of the second adhesive sandwich component 140 to the side of the next battery cell n... and so on, the gluing work of multiple battery cells n is realized in sequence.
