The gluing device includes a gluing mechanism 1, a gluing feeding mechanism 2, a gluing supply mechanism 3, a guiding mechanism 4, a detecting mechanism 51, a length measuring mechanism 52, a waste tape rejecting mechanism 6 and a buffer mechanism 7. The gluing device is arranged on a mounting plate 8, and the battery cell is wound on a winding needle mechanism 9. In order to facilitate the gluing device to glue the battery cell, especially the terminal end of the battery cell, the gluing device is arranged close to the winding needle mechanism 9, and the gluing mechanism 1 can move and abut against the winding needle mechanism 9, so as to facilitate gluing.

[0049] Figure 2 The figure shows a top view of a gluing mechanism of a gluing device according to an embodiment of the present application. Figure 3 The figure shows a bottom view of a glue sticking mechanism of a glue sticking device according to an embodiment of the present application. Figure 4 The figure shows a front view of a glue sticking mechanism of a glue sticking device according to an embodiment of the present application, Figures 2 to 4As shown, the gluing mechanism 1 includes a gluing assembly 11, a translation assembly 12 and a gluing pressing assembly 13. The translation assembly 12 is connected to the gluing assembly 11 and the gluing pressing assembly 13, and is used to drive the gluing assembly 11 and the gluing pressing assembly 13 to approach or move away from the battery cell on the needle winding mechanism 9. The gluing assembly 11 includes a gluing roller 111, a gluing driving assembly and a gluing guiding assembly. The gluing driving assembly includes a gluing cylinder 112 and a gluing cylinder fixing seat 113. The gluing guiding assembly includes a gluing slide plate 114, a gluing slider 115 and a gluing slide rail 116. The gluing assembly 11 also includes a gluing fixing seat 117, a spring bracket 118 and a gluing roller bracket 119. The gluing roller bracket 119 and the spring bracket 118 are connected by a spring 181. The translation assembly 12 includes a translation drive assembly, a translation slide 122, a translation drive block 123, a translation slider 124 and a translation slide rail 125, and the translation drive assembly includes a translation cylinder 121. The glue pressing assembly 13 includes a pressing block 131, a support rod 132, a glue pressing drive assembly, a glue pressing guide rod 135, a glue pressing drive block 136 and a support rod mounting seat 137, and the glue pressing drive assembly includes a glue pressing cylinder 133 and a glue pressing cylinder fixing seat 134.

[0050] The translation cylinder 121 and the translation rail 125 of the translation assembly 12 are arranged on the mounting plate 8, the output end of the translation cylinder 121 is connected to the translation drive block 123, the translation drive block 123 is connected to the translation slide 122, and the translation slide 122 can reciprocate along the first direction AA under the drive of the translation cylinder 121. At the same time, the translation slide 122 is connected to the translation rail 125 through the translation slider 124, so as to ensure the stability of the translation slide 122 when moving along the first direction AA, so that the translation slide 122 can approach or move away from the battery cell of the winding needle mechanism 9. The first direction described in this embodiment refers to the direction in which the glue sticking mechanism 1 approaches or moves away from the battery cell, that is, reciprocates along the AA direction shown in the figure, but it should be noted that, unless otherwise specified, the movement along the AA direction described in this application includes reciprocating movement along the AA direction. In addition, this application is not limited to movement in one direction AA, and designers can select a suitable movement direction of the glue sticking mechanism 1 according to specific design requirements and space layout needs.

[0051] In order to reasonably utilize the space for structural layout, the technical solution provided by the present application is that the glue pressing component 13 is located downstream of the glue sticking component 11 along the conveying direction of the tape. Figure 4. The glue pressing assembly 13 is connected to the translation slide 122 of the translation assembly 12, and the movement of the translation slide 122 drives the glue pressing assembly 13 to move along the first direction AA. The glue pressing cylinder 133 of the glue pressing assembly 13 is connected to the glue pressing cylinder fixing seat 134, and the glue pressing cylinder fixing seat 134 is connected to one side of the translation slide 122. The output end of the glue pressing cylinder 133 is connected to the glue pressing drive block 136, and the glue pressing drive block 136 is connected to one end of the glue pressing guide rod 135. The glue pressing guide rod 135 passes through the translation slide 122 and can move along the translation slide 122. The glue pressing cylinder 133, the glue pressing cylinder fixing seat 134 and the glue pressing drive block 136 are all arranged on one side of the translation slide 122 ( Figure 3 The left side of the slide 122 ( Figure 3 A pressing block 131 and a support rod 132 are provided (on the right side in the figure), and the pressing block 131 is connected to the other end of the glue pressing guide rod 135. Therefore, when the glue pressing cylinder 133 drives the glue pressing driving block 136 to move along the first direction AA, it can drive the glue pressing guide rod 135, and then drive the pressing block 131 to move along the first direction AA. The support rod 132 is connected to the translation slide 122 through the support rod mounting seat 137. Therefore, when the pressing block 131 moves along the first direction AA, it can approach or move away from the support rod 132. The support rod 132 is arranged perpendicular to the mounting plate 8, and in the embodiment provided by the present application, the tape is also perpendicular to the mounting plate 8. The pressing block 131 and the support rod 132 are arranged opposite to each other, and the end of the tape extends between the two. Therefore, when the pressing block 131 approaches or moves away from the support rod 132, the end of the tape can be clamped or released.

[0052] Furthermore, in the embodiment provided by the present application, the pressing block 131 is in the shape of a flat plate, and the side where the pressing block 131 abuts against the support rod 132 includes a first serrated edge. The pressing block 131 with this structure can not only abut against the support rod 132 to clamp the end of the tape, but can also cooperate with other mechanisms, such as the clamping plate assembly at the end of the conveying tape. The clamping plate assembly is designed as a serrated structure that cooperates with the pressing block 131. The engagement between the serrations allows the pressing block 131 and the clamping plate assembly to be more tightly combined, thereby accurately receiving the end of the tape and transferring the end of the tape to the adhesive assembly 11 provided in the embodiment of the present application. The specific content will be elaborated in detail later. Designers in this field can design a pressing block 131 with a suitable structure according to actual needs.

[0053] The glue component 11 is also connected to the translation slide 122 of the translation component 12. Specifically, a glue rail 116 is arranged above the translation slide 122, and a glue slider 115 is arranged on the glue rail 116 and can move along the glue rail 116. A glue slide plate 114 is arranged on the glue slider 115. The glue cylinder 112 of the glue component 11 is connected to the glue cylinder fixing seat 113, and the glue cylinder fixing seat 113 is connected to the translation slide 122. The glue cylinder 112 is connected to the glue slide plate 114. Therefore, when the glue cylinder 112 moves, it can drive the glue slide plate 114 to move along the first direction AA. The glue sliding plate 114 is connected to the glue fixing seat 117, one end of the glue roller bracket 119 is rotatably connected to the glue fixing seat 117, the other end of the glue roller bracket 119 is connected to the glue roller 111, and the glue roller 111 can rotate around the glue roller bracket 119, and the rotation center NN of the glue roller 111 is perpendicular to the mounting plate 8.

[0054] It should be noted that the function of the translation component 12 is to drive the gluing component 11 and the pressing component 13 to move closer to or away from the battery cell. Therefore, as long as the above requirements can be met, the driving direction of the translation component 12 may be different from the driving direction of the gluing component 11 and the pressing component 13. The designer can reasonably design the specific driving direction based on the gluing mechanism 1 and the layout of the battery cell.

[0055] The glue cylinder 112 can move the glue roller 111 to a position close to or away from the battery cell through the glue sliding plate 114. When the battery cell contacts the glue roller 111, the glue roller 111 is tangential to the battery cell. When the battery cell rotates, the glue roller 111 is subjected to a tangential force due to the friction between the two. At the same time, since the glue roller bracket 119 is rotatably connected to the glue fixing seat 117, the glue roller 111 can drive the glue roller bracket 119 to swing along the conveying direction of the tape while rotating, thereby pressing the tape onto the battery cell. In addition, the glue sliding plate 114 is perpendicular to the mounting plate 8 and spring brackets 118 are respectively provided at both ends. The two ends of the glue roller bracket 119 are connected to the spring bracket 118 by springs 181. In the absence of external force, the glue roller bracket 119 can be restored to the position as shown in the figure. Figure 4 Position shown.

[0056] Figure 5The figure shows a partial enlarged view of 1-1 of the gluing mechanism of a gluing device of an embodiment of the present application. The gluing fixing seat 117 is connected to the gluing roller bracket 119, and the gluing roller bracket 119 can rotate around the rotation axis 191. Further, in order to limit the rotation angle of the gluing roller bracket 119 and prevent the gluing roller 111 from failing due to excessive rotation angle, the side of the gluing fixing seat 117 connected to the gluing roller bracket 119 includes a rotating inclined surface 171 and a rotating plane 172. The rotating inclined surface 171 and the rotating plane 172 can be two connected surfaces or two unconnected surfaces. The rotating inclined surface 171 and the rotating plane 172 are respectively perpendicular to the mounting plate 8, and the rotating plane 172 is perpendicular to the first direction AA. The rotating inclined surface 171 is inclined to the side away from the gluing roller bracket 119. One side of the gluing roller bracket 119 includes a plurality of limit blocks, and the plurality of limit blocks can respectively abut against the rotating inclined surface 171 and the rotating plane 172, thereby limiting the rotation angle of the gluing roller bracket 119. Specifically, when the rubber roller bracket 119 rotates toward the direction approaching the rotating inclined surface 171, the limit block 192 can preferentially touch and abut the rotating inclined surface 171, thereby limiting the further rotation of the rubber roller bracket 119; conversely, when the rubber roller bracket 119 rotates toward the direction approaching the rotating plane 172, the limit block 193 can preferentially touch and abut the rotating plane 172, thereby limiting the further rotation of the rubber roller bracket 119.

[0057] The end of the tape is clamped by the glue pressing assembly 13 and extends to a certain length, so that the glue roller 111 can touch the end of the tape, and the translation assembly 12 drives the glue pressing assembly 11 and the glue pressing assembly 13 to move close to the battery cell, and the glue cylinder 112 drives the glue roller 111 to move closer to the battery cell. At this time, the glue roller 111 can press the end of the tape to the terminal end of the battery cell. When pressing the end of the tape, the glue roller 111 rotates around the rotating shaft 191 ( Figure 1 The adhesive roller 111 is rotated counterclockwise in the middle of the battery cell to roll along the surface of the battery cell to press the end of the adhesive tape against the battery cell. After pressing the end of the adhesive tape, the adhesive pressing assembly 13 is released, and the end of the adhesive tape drives the adhesive tape to automatically wrap around the battery cell as the battery cell rotates. At the same time, since the adhesive roller 111 remains in contact with the battery cell, the adhesive tape can be pressed by the adhesive roller 111 when winding, thereby pressing the terminal end of the battery cell tightly.

[0058] Figure 6-Figure 9 The figure shows the glue feeding mechanism of the glue sticking device according to one embodiment of the present application. Figure 6-Figure 9, the glue feeding mechanism 2 includes a glue cutting mechanism (not marked) and a glue pulling mechanism (not marked), wherein the glue cutting mechanism includes a cutter assembly 21 and a avoidance assembly 24, and the glue pulling mechanism includes a moving assembly 22 and a clamping plate assembly 23. In order to simplify the product structure of the glue sticking device, the embodiment provided by the present application combines the glue cutting mechanism and the glue pulling mechanism into one, and the two share a moving assembly 22. It should be noted that the moving assembly 22 is used to make the cutter assembly 21 and the clamping plate assembly 23 close to the glue sticking mechanism 1 along the conveying direction of the tape, so that the cutter assembly 21 can cut the tape at any position. Therefore, the cutter assembly 21 and the clamping plate assembly 23 can be independently provided with corresponding moving assemblies 22, but in order to simplify the product structure and control the cost, the embodiment provided by the present application integrates the cutter assembly 21 and the clamping plate assembly 23 on a moving assembly 22. In order to better play the role of the cutter assembly 21, the clamping plate assembly 23 is added, and the tape is clamped by the clamping plate assembly 23, so that the cutter assembly 21 can better cut the tape.

[0059] The mobile assembly 22 provided in the present application includes a mobile drive assembly, a transmission assembly, a lead screw 261, a lead screw support 262 and a lifting guide assembly. Among them, the mobile drive assembly includes a drive motor 221 and a motor fixing seat 222, and the transmission assembly includes a driving wheel 223, a transmission belt 224 and a driven wheel 225. The driving wheel 223 is connected to the output end of the drive motor 221, and the driven wheel 225 and the driving wheel 223 are connected by a transmission belt 224, so that the rotation of the drive motor 221 is transmitted to the driven wheel 225. The lead screw 261 is arranged along the second direction BB, and one end of the lead screw 261 is connected to the driven wheel 225, and when the driven wheel 225 rotates, it can drive the lead screw 261 to rotate synchronously. The lead screw 261 is arranged on the lead screw support 262 and can rotate on the lead screw support 262, and the lead screw support 262 is connected to the mounting plate 8. The mobile guide assembly includes a glue-pulling slide 227, a mobile slider 228 and a mobile slide rail 229. The mobile slide rail 229 is arranged on the mounting plate 8 and extends in the second direction BB. The mobile slider 228 is arranged on the mobile slide rail 229, and the mobile slider 228 is connected to the glue-pulling slide 227. The lead screw 261 is sleeved on the glue-pulling slide 227 through a nut (not shown). Therefore, when the lead screw 261 rotates with the driven wheel 225, it can drive the glue-pulling slide 227 to move in the second direction BB, thereby realizing the moving function. It should be noted that the movement in the BB direction described in this application, unless otherwise specified, includes reciprocating movement in the BB direction. In the embodiment provided in this application, the second direction BB is parallel to the plane where the mounting plate 8 is located, and is perpendicular to the first direction AA. Therefore, the moving assembly 22 can drive the cutter assembly 21 to move in the conveying direction of the tape.

[0060] The clamping plate assembly 23 includes a clamping portion, a clamping plate driving assembly, a clamping plate fixing seat 236, a clamping plate guide assembly and an air blowing clamping block, and the clamping plate driving assembly drives the clamping portion to clamp the adhesive tape. The clamping portion includes a first clamping plate 231 and a second clamping plate 233, and the first clamping plate 231 is fixedly connected, such as being connected to the clamping plate fixing seat 236 through a first clamping plate bracket 232, and the clamping plate fixing seat 236 is connected to the adhesive drawing slide 227, or the first clamping plate 231 is directly connected to the adhesive drawing slide 227. The second clamping plate 233 is connected to the clamping plate driving assembly, and the clamping plate driving assembly drives the second clamping plate 233 to approach or move away from the first clamping plate 231 along the first direction AA. The splint drive assembly includes a splint cylinder 237 and a splint cylinder fixing seat 238 for fixing the splint cylinder 237. The output end of the splint cylinder 237 is connected to the second splint 233, driving the second splint 233 to move relative to the first splint 231 to clamp or release the tape between the two. The splint cylinder fixing seat 238 is set on the splint fixing seat 236.

[0061] In the embodiment provided by the present application, the first direction AA is parallel to the plane where the mounting plate 8 is located. The clamping plate guide assembly includes a clamping plate slider 234 and a clamping plate slide rail 235. The clamping plate slide rail 235 is arranged on the clamping plate fixing seat 236 and extends along the first direction AA. The clamping plate slider 234 is arranged on the clamping plate slide rail 235. The clamping plate slider 234 is connected to the second clamping plate 233. The output end of the clamping plate cylinder 237 is connected to the second clamping plate 233 and drives the second clamping plate 233 to move along the clamping plate slide rail 235, thereby driving the second clamping plate 233 to move along the first direction AA.

[0062] Since the clamping plate fixing seat 236 is connected to the glue pulling slide 227, when the clamping plate assembly 23 clamps the adhesive tape, the moving assembly 22 can drive the clamping plate assembly 23 to drive the adhesive tape to move along the second direction BB. In the embodiment provided by the present application, the first clamping plate 231 includes a second serrated edge, the first clamping plate 231 is arranged perpendicular to the mounting plate 8, and when the clamping plate assembly 23 is moving, the second serrated edge of the first clamping plate 231 can be preferentially moved to a preset position. This structure is adopted to cooperate with other mechanisms in the glue sticking device, such as the glue pressing assembly 13 in the glue sticking mechanism 1 includes a pressing block 131 that cooperates with the first clamping plate 231, and the side of the pressing block 131 that abuts against the support rod 132 includes a first serrated edge. After moving, the second serrated edge of the first clamping plate 231 can be engaged with the first serrated edge, so that the clamping plate assembly 23 and the glue sticking mechanism 1 can be tightly combined, and the adhesive tape clamped by the clamping plate assembly 23 can be accurately transferred to the glue sticking mechanism 1, so as to prepare for subsequent processes.

[0063] The clamp assembly 23 also includes an air blowing clamp block, which includes a vent pipe 391 and a vent joint 392. The air blowing clamp block can blow air so that the end of the tape is attached to the first clamp plate 231 without swinging freely, thereby preventing the end of the tape from bending and causing the subsequent adhesive bonding mechanism to be unable to fix the end of the tape. In order to further optimize the structure, in an embodiment of the present application, the air blowing clamp block is connected to the second clamp plate 233 and integrated with it, and a plurality of vent holes are provided on the upper surface of the vent pipe 391. Gas is injected into the vent pipe 391 through the vent joint 392, and the gas is blown onto the tape through the plurality of through holes, so that the end of the tape is attached to the first clamp plate 231.

[0064] In order to facilitate cutting of the tape, the cutter assembly 21 can be arranged at the output end of the moving assembly 22, that is, on the glue pulling slide 227. When the end of the tape is attached to the battery cell by the glue sticking mechanism 1, the tape is still clamped by the clamping plate assembly 23, and the cutter assembly 21 can be moved to any position between the glue sticking mechanism 1 and the clamping plate assembly 23 through the moving assembly 22, so that the cutter assembly 21 can cut the tape at any position between the clamping plate assembly 23 and the glue sticking mechanism 1, thereby cutting out any length of tape.

[0065] The cutter assembly 21 includes a cutter 211, a cutter fixing seat 212, a cutter mounting seat 213, a rubber cutting guide assembly and a rubber cutting drive assembly. The rubber cutting drive assembly includes a cutter cylinder 218, and the rubber cutting guide assembly includes a rubber cutting guide rod 216 and a cutter guide seat 217. The rubber cutting guide rod 216 extends along a first direction AA, and the rubber cutting guide rod 216 penetrates the cutter guide seat 217 and can move in the cutter guide seat 217. One end of the rubber cutting guide rod 216 is connected to the cutter mounting seat 213, and the output end of the cutter cylinder 218 is connected to the cutter mounting seat 213. Therefore, when the cutter cylinder 218 drives the cutter mounting seat 213 to move along the first direction AA, the cutter 211 can be driven to move along the first direction AA.

[0066] The cutter 211 is arranged perpendicular to the plane where the mounting plate 8 is located, and the cutter 211 is perpendicular to the plane where the first clamping plate 231 and the second clamping plate 233 are located, and the plane where the first clamping plate 231 and the second clamping plate 233 are located is perpendicular to the plane where the mounting plate 8 is located. Therefore, when the tape is clamped by the first clamping plate 231 and the second clamping plate 233, the blade of the cutter 211 can be perpendicular to the plane where the tape is located, so that the cutter 211 can act on the tape when moving along the first direction AA. Therefore, the cutter cylinder 218 can drive the cutter 211 to cut the tape along a direction perpendicular to the conveying direction of the tape.

[0067] The cutter 211 is arranged on a cutter fixing seat 212, and the cutter fixing seat 212 is arranged on a cutter mounting seat 213, and the cutter fixing seat 212 can be detachably connected to the cutter mounting seat 213. In order to quickly remove or replace the cutter 211, a preferred embodiment is that the cutter fixing seat 212 slides out along the cutter mounting seat 213, and the sliding direction is a third direction CC, and the third direction CC is perpendicular to the mounting plate 8, that is, the cutter fixing seat 212 is pulled out and away from the mounting plate 8, so as to replace the cutter 211 thereon. Furthermore, an adjustment handle 214 and a handle 215 are arranged at one end of the cutter fixing seat 212 away from the mounting plate 8, and the adjustment handle 214 passes through the cutter fixing seat 212 and is threadedly connected to the cutter mounting seat 213, and the cutter fixing seat 212 can be separated from the cutter mounting seat 213 by rotating the adjustment handle 214, and the cutter fixing seat 212 can be quickly pulled out by the handle 215.

[0068] In actual implementation, the glue sticking mechanism 1 is located above the glue feeding mechanism 2. When the moving assembly 22 drives the clamping plate assembly 23 to deliver the adhesive tape to the glue sticking mechanism 1, the glue cutting mechanism will follow the moving assembly 22 and move close to the glue sticking mechanism 1 and generate motion interference with the glue sticking mechanism 1. Therefore, the glue cutting mechanism also needs to include a position avoidance assembly 24. The position avoidance assembly 24 includes a position avoidance driving assembly and a position avoidance guide assembly. The position avoidance guide assembly includes a position avoidance slide 244, a position avoidance slider 245 and a position avoidance slide rail 246. The position avoidance slide rail 246 is connected to the glue pulling slide 227 and extends along the second direction BB. The position avoidance slider 245 is set on the position avoidance slide rail 246 and moves along the position avoidance slide rail 246. The position avoidance slider 245 is connected to the position avoidance slide 244. The avoidance drive assembly includes an avoidance cylinder 241, an avoidance cylinder fixing seat 242 and an avoidance drive connecting block 243. The avoidance cylinder 241 is fixed on the adhesive pull slide 227 through the avoidance cylinder fixing seat 242. The output end of the avoidance cylinder 241 is connected to the avoidance slide 244 through the avoidance drive connecting block 243 and drives the avoidance slide 244 to move along the second direction BB. The cutter guide seat 217 is arranged on the avoidance slide 244, so that the avoidance cylinder 241 can drive the avoidance slide 244 to drive the cutter guide seat 217 to move along the conveying direction of the adhesive tape, that is, the second direction BB.

[0069] The driving end of the avoidance component 24 is connected to the cutter guide seat 217, and is used to drive the cutter 211 to move along the conveying direction of the tape. When avoidance is required, the avoidance component 24 drives the cutter 211 to move in the direction away from the gluing mechanism 1, that is, to move downward along the second direction BB; when the tape needs to be cut, the avoidance component 24 drives the cutter 211 to move in the direction close to the gluing mechanism 1 and extend out of the clamping plate component 23, so that it is located between the clamping plate component 23 and the gluing mechanism 1.

[0070] In order to further optimize the structural layout of the glue feeding mechanism 2, in the embodiment provided in the present application, the cutter mounting seat 213 is connected to the cutter guide seat 217, and the cutter guide seat 217 is arranged on the avoidance slide 244, and the avoidance slide 244 is slidably connected to the glue pulling slide 227 through the avoidance slider 245 and the avoidance slide rail 246, so that the cutter mounting seat 213 is connected to the moving component 22 and the avoidance component 24.

[0071] Fig.10 , Fig.11 The figure shows the glue supply mechanism of the glue sticking device according to one embodiment of the present application. Fig.10 , Fig.11 The glue supply mechanism 3 includes an unwinding shaft 31 and an unwinding shaft mounting plate 32, and the unwinding shaft 31 is rotatably arranged on the unwinding shaft mounting plate 32. The tape roll is mounted on the unwinding shaft 31, and the unwinding shaft 31 can be rotated to release the tape on the tape roll. In the glue supply device provided by the prior art, the tape roll is clamped and fixed by two mutually parallel clamping plates on the unwinding shaft 31. When the two end surfaces of the tape roll are uneven, the clamping and fixing of the tape roll is not stable. In the technical solution provided by the present application, a first boss 311 and a second boss 312 are relatively arranged on both sides of the unwinding shaft 31. Preferably, the opposing surfaces of the first boss 311 and the second boss 312 are conical surfaces, and the first boss 311 and the second boss 312 are coaxially arranged. A clamping block 313 is sleeved on the unwinding shaft 31, and the clamping block 313 is used to limit the tape roll from escaping along the axial direction of the unwinding shaft 31. The barrel of the tape roll is sleeved on the unwinding shaft 31 and does not contact the unwinding shaft 31 , and both ends are respectively clamped between the first boss 311 and the second boss 312 , so that the tape roll is fixed more stably.

[0072] Since the tape roll is positioned by the edge of the tape roll when installed on the unwinding shaft 31, and is positioned by the center line of the tape when in use, when the specifications of the tape are different, that is, the width of the tape is different, the position of the tape is easily offset, thereby affecting its use. Therefore, the glue supply mechanism 3 also includes an adjustment component 33, which is used to adjust the position of the tape roll along the axial direction of the unwinding shaft 31.

[0073] The adjustment assembly 33 includes an adjustment seat 331, an adjustment guide assembly, a locking assembly and an indication assembly. The adjustment guide assembly includes an adjustment rail 332, an adjustment slider 333 and a sliding plate 334. The sliding plate 334 is connected to the unwinding shaft mounting plate 32. The adjustment slider 333 is connected to the sliding plate 334. The adjustment rail 332 is arranged on the adjustment seat 331 along an axial direction parallel to the unwinding shaft 31. The adjustment slider 333 can move along the adjustment rail 332. The locking assembly includes a locking block 335 and a locking member 336. The locking block 335 is arranged on the sliding plate 334. The locking block 335 is used to hold or loosen the adjusting slide rail 332 through the locking member 336. If the locking member 336 is a fastening screw, the locking member 336 is threadedly connected to the locking block 335 and passes through the locking block 335 to abut against the adjusting slide rail 332. When the locking member 336 rotates and presses against the adjusting slide rail 332, the locking block 335 can be locked. During adjustment, the position of the unwinding shaft 31 can be adjusted by sliding the adjusting slider 333 on the adjusting slide rail 332. After the position is adjusted, the locking block 335 is locked by the locking member 336 so that the locking block 335 holds the adjusting slide rail 332 tightly, thereby fixing the position of the unwinding shaft 31 and preventing the unwinding shaft 31 from moving axially during use. Furthermore, the adjustment component 33 includes an indicating device, such as a scale 337 provided on the adjustment seat 331 and a pointer 338 provided on the sliding plate 334. The position of the unwinding shaft 31 can be accurately adjusted by using the scale 337 and the pointer 338.

[0074] Since the battery core is wound on the winding needle mechanism 9, when the glue sticking mechanism 1 moves close to the winding needle mechanism 9, the direction of the adhesive tape changes, and it is easy to scratch the clamping plate assembly 23. Therefore, the glue sticking device also includes a guiding mechanism. Fig.12The figure shows a top view of the guide mechanism of the glue sticking device of one embodiment of the present application. The guide mechanism 4 is arranged between the glue sticking mechanism 1 and the clamping plate assembly 23. The guide mechanism 4 includes a guide roller 41, a guide roller fixing seat 42, a guide slider 43, a guide slide rail 44 and a guide drive assembly. The guide drive assembly includes a guide cylinder 45 and a guide cylinder fixing seat 46. The guide roller 41 is rotatably arranged on the guide roller fixing seat 42, and the guide roller 41 is arranged perpendicular to the mounting plate 8. The guide roller fixing seat 42 is arranged on the guide slider 43, and the guide slider 43 is slidably arranged on the guide slide rail 44, and the guide slide rail 44 is arranged on the mounting plate 8. The guide cylinder 45 is arranged on the mounting plate 8 through the guide cylinder fixing seat 46. The driving end of the guide cylinder 45 is connected to the guide roller fixing seat 42. The guide cylinder 45 can drive the guide roller fixing seat 42 to drive the guide roller 41 to move along the first direction AA. Before the glue-applying mechanism 1 moves close to the needle winding mechanism 9, the guide cylinder 45 can drive the guide roller 41 to abut against the side of the adhesive tape away from the clamping plate assembly 23, so that the other parts of the adhesive tape except the end remain straight. In addition, before the glue-feeding mechanism 2 moves to the glue-applying mechanism 1 to feed glue and cut the adhesive tape, the guide cylinder 45 can drive the guide roller 41 away from the adhesive tape to prevent interference with the operation of the glue-feeding mechanism 2.

[0075] Fig.13 The left view of the detection mechanism of the adhesive sticking device of one embodiment of the present application is shown. The detection mechanism 51 includes a mark sensor 511 and a sensor bracket 512. The sensor bracket 512 is arranged on the mounting plate 8. The mark sensor 511 is arranged on the sensor bracket 512 for detecting the mark on the tape. In order to ensure that the set length of tape is pasted on the large battery cell, marks can be arranged on the tape at intervals along the length direction of the tape. The mark can be different from the tape itself in transparency or in color. The set length is the length between the two marks, that is, the tape between the two marks needs to be cut. Therefore, the detection mechanism 51 is used to detect the mark on the tape to control the cutter 211 to cut the set length of the tape. In order not to affect the transmission of the tape, the sensor bracket 512 is arranged perpendicular to the mounting plate 8, and two mark sensors 511 are arranged on the sensor bracket 512 along the direction perpendicular to the tape to detect the mark on the tape. The mark sensor 511 includes a photoelectric sensor, preferably a linear photoelectric sensor, which can reduce the false detection caused by bubbles on the tape and is used to detect the difference between the transparency of the mark and the transparency of the tape itself. In another preferred embodiment, the mark sensor 511 is a color sensor that detects the difference between the color of the mark and the color of the tape. After the mark sensor 511 detects the mark on the tape, it outputs a mark signal to the control system, and the control system can control the cutter 211 to cut the tape after receiving the mark signal.

[0076] Fig.14The left side view of the length measuring mechanism of the glue sticking device of one embodiment of the present application is shown. The length measuring mechanism 52 is arranged on the side of the detection mechanism 51 away from the glue sticking mechanism 1. The length measuring mechanism 52 includes a length measuring shaft 521, a length measuring roller 522, a length measuring sensor 523 and a length measuring induction body 524, wherein the length measuring shaft 521 is coaxially arranged with the length measuring roller 522 and the length measuring roller 522 can rotate around the length measuring shaft 521, the length measuring shaft 521 is arranged on the mounting plate 8 and is arranged perpendicular to the mounting plate 8, and the length measuring sensor 523 is arranged on the mounting plate 8. 3 is arranged on the length measuring shaft 521, and the length measuring induction body 524 is arranged on the length measuring roller 522. When the adhesive tape is being transported, it can be close to the length measuring roller 522 to drive the length measuring roller 522 to rotate. After the length measuring roller 522 rotates, it drives the length measuring induction body 524 to rotate. The length measuring sensor 523 can detect the rotation of the length measuring induction body 524, thereby recording the number of rotations and angles of the length measuring induction body 524 and sending a length measuring signal to the control system. After the control system obtains the length measuring signal, it controls the cutter assembly 21 to cut the adhesive tape.

[0077] In order to prevent the detection mechanism 51 from missing the mark, resulting in the failure to cut the set length of the tape, the length measuring mechanism 52 can be used to calculate the transmission length of the tape, so as to determine whether the detection mechanism 51 has missed the detection, and send a signal in time to make the cutter assembly 21 cut the tape. By calculating the number of revolutions and angles of the length measuring roller 522 relative to the length measuring shaft 521, the transmission length of the tape can be measured according to the circumference of the length measuring roller 522. Assuming that the length between the two marks is 200mm, the detection mechanism 51 does not detect the mark, but the tape has actually been transmitted 210mm, at this time, the length measuring mechanism 52 can send a signal to the control system to control the cutter assembly 21 to cut the tape when the error between the measured transmission length of the tape and the position of the mark exceeds a certain range.

[0078] Fig.15 The figure shows a front view of a waste tape removal mechanism of a gluing device according to an embodiment of the present application. Fig.16 The figure shows a top view of a waste tape removal mechanism of a glue sticking device according to an embodiment of the present application, Fig.15 , Fig.16As shown, the waste tape removal mechanism 6 includes a reel 61, a rotating shaft 62, a rotating support seat 63, a recycling drive assembly and a recycling transmission assembly, wherein the recycling drive assembly includes a recycling motor 65 and a recycling motor fixing seat 64, and the recycling transmission assembly includes a recycling driving wheel 66, a recycling transmission belt 67 and a recycling driven wheel 68. The waste tape removal mechanism 6 is arranged on the side of the gluing mechanism 1 away from the cutter assembly 21, the reel 61 is detachably sleeved on the rotating shaft 62 and is coaxially arranged with the rotating shaft 62, and a card slot 611 is arranged on the reel 61, and the card slot 611 extends along the axial direction of the reel 61, and the end of the tape can be clamped in the card slot 611 and rotate with the reel 61. The reel 61 is quickly detachably arranged on the rotating shaft 62 by two fasteners 621. The two fasteners 621 press the reel 61 along the diameter direction of the rotating shaft 62 and perpendicular to each other, and the fastener 621 can be a spring plunger. The rotating shaft 62 is rotatably set on the rotating support seat 63, the rotating support seat 63 is set on the recycling motor fixing seat 64, the recycling motor 65 is set on the recycling motor fixing seat 64, the driving end of the recycling motor 65 is provided with a recycling driving wheel 66, and the other end of the rotating shaft 62 is provided with a recycling driven wheel 68, and a recycling transmission belt 67 is connected between the recycling driving wheel 66 and the recycling driven wheel 68.

[0079] Since the end of each roll of tape has poor quality, the end portion needs to be cut off, and the cut portion is collected by the waste tape rejection mechanism 6. The recovery motor 65 can drive the recovery active wheel 66 to drive the recovery driven wheel 68 to further drive the rotating shaft 62 and the winding shaft 61 to rotate. Before the tape is used, the end of the tape can be clamped on the clamping slot 611 of the winding shaft 61, and the recovery motor 65 drives the winding shaft 61 to rotate to wind the end of the tape. Since there is generally no mark on the end of the tape, the tape with the mark position set is generally of better quality. When the detection mechanism 51 detects the set number of marks, the recovery motor 65 can be controlled to stop winding, and the cutter assembly 21 then cuts the tape.

[0080] Fig.17What is shown is a front view of a cache mechanism of a glue laminating device of an embodiment of the present application. The cache mechanism 7 is arranged between the glue supply mechanism 3 and the length measuring mechanism 52. The cache mechanism 7 includes a cache component 71, a counterweight component 72 and a glue clamping component 73. The cache component 71 includes a cache drive component, a cache guide component and a cache roller 713. The cache drive component includes a cache cylinder 711 and a cache connecting block 712. The cache guide component includes a cache slider 714 and a cache slide rail 715. The cache roller 713 is arranged on the cache slider 714 and is perpendicular to the mounting plate 8. The driving end of the cache cylinder 711 is connected to the cache slider 714 through the cache connecting block 712. The cache slider 714 is slidably arranged on the cache slide rail 715. The cache slide rail 715 is arranged along the second direction BB. The cache cylinder 711 can drive the cache slider 714 to drive the cache roller 713 to move along the second direction BB.

[0081] The cache mechanism 7 also includes a glue clamping assembly 73, which is arranged between the cache assembly 71 and the length measuring mechanism 52. The glue clamping assembly 73 includes a glue clamping cylinder 731, a clamping block 732 and a glue clamping roller 733. The glue clamping roller 733 is arranged perpendicular to the mounting plate 8. The tape is wound around the glue clamping roller 733. The glue clamping cylinder 731 pushes the clamping block 732 to move to the glue clamping roller 733 to clamp the tape.

[0082] See also Figure 1 Since the transmission direction of the adhesive tape is from the adhesive supply mechanism 3 to the buffer mechanism 7 and then to the length measuring mechanism 52, when a section of adhesive tape needs to be temporarily stored, the buffer mechanism 7 can be used to complete the temporary storage of the adhesive tape. Fig.17 In order to prevent the buffer mechanism 7 from pulling the tape in the opposite direction of conveying when caching the tape, the tape is clamped by the glue clamping assembly 73 before caching the tape, and the tape is conveyed to the buffer mechanism 7 through the glue supply mechanism 3. The buffer assembly 71 is moved along the second direction BB to pull the tape for a distance, thereby realizing the storage of the tape. Furthermore, in order to enable the tape to be smoothly conveyed from the glue supply mechanism 3 to the buffer mechanism 7, a roller 716 is provided on the side of the buffer assembly 71 close to the glue supply mechanism 3, and the roller 716 is provided perpendicular to the mounting plate 8. Preferably, the roller 716 and the glue clamping roller 733 are symmetrically arranged along the buffer slide rail 715. Therefore, the tape is wound around the roller 716, then around the buffer roller 713, and then around the glue clamping roller 733.

[0083] In order to facilitate the movement of the buffer slider 714, the buffer mechanism 7 also includes a counterweight assembly 72, which includes a counterweight block 721 and a counterweight guide assembly, and the counterweight guide assembly includes a counterweight slide rail 722 and a counterweight slider 723. The counterweight slide rail 722 is arranged on the mounting plate 8, and the counterweight slider 723 can move along the counterweight slide rail 722. The counterweight block 721 is arranged on the counterweight slider 723 and can move along the counterweight slide rail 722 under the action of its own weight. The counterweight block 721 is connected to the counterweight connecting block 724, and the counterweight connecting block 724 is connected to the buffer connecting block 712 through a conveyor belt 726. The conveyor belt 726 includes but is not limited to a belt. The counterweight assembly 72 can assist the buffer assembly 71 to move along the second direction BB through the conveyor belt 726. One end of the conveyor belt 726 is parallel to the counterweight slide rail 722, and the other end of the conveyor belt 726 bypasses the fixed pulley 725 to connect to the buffer connecting block 712, and the other end of the conveyor belt 726 is parallel to the buffer slide rail 715. By using the conveyor belt 726 and the fixed pulley 725, the counterweight block 721 can be moved in the direction of its own weight, and the buffer assembly 71 can be pulled to move in the opposite direction along the second direction BB, thereby releasing the stored tape. At the same time, since the gravity generates horizontal pressure, the counterweight slider 723 does not slide smoothly on the counterweight slide rail 722, and this solution can effectively prevent the counterweight block 721 from moving obliquely.

[0084] Furthermore, the technical solution provided by the present application also includes a power supply, an air supply system and a control system. The air supply system is such as an air compressor, an air pump, etc., which drives the operation of the above multiple cylinders through the air supply system, and blows air to the vent pipe 391 through the air blowing clamp vent connector 392, so that the end of the tape can be attached to the first clamping plate 231 to prevent the end from bending. In addition, the control system is used to control the operation of each mechanism, especially to control the cutter assembly 21 to cut the tape after receiving the signal of the mark sensor 511 and / or the length sensor 523.

[0085] The glue sticking device provided in the present application can not only realize the glue sticking of small battery cells, but also realize the glue sticking of large battery cells, and has strong compatibility and a wide range of applications; the end of the tape can be rolled and stuck on the terminal end of the battery cell, and the glue sticking is relatively secure; in addition, the tape can be directly stuck on the terminal end of the battery cell, and the tape can be cut into an appropriate length according to the set length, which occupies little space, has a simple glue sticking process, is low in cost, and has a high glue sticking efficiency.

[0086] Fig.18 The flowchart of the adhesive application method according to one embodiment of the present application is used to apply adhesive tape to the terminal end of the battery cell, and the adhesive application device described above is applied, including the following steps:

[0087] S161: driving the second clamping plate of the clamping plate assembly to move toward the first clamping plate and clamp the end of the tape;

[0088] S162: driving the clamping plate assembly to move toward the gluing mechanism and convey the end of the tape;

[0089] S163: driving the adhesive laminating mechanism to clamp the end of the adhesive tape;

[0090] S164: driving the second clamping plate away from the first clamping plate and releasing the end of the tape;

[0091] S165: driving the adhesive tape mechanism to abut against the battery cell and rolling the adhesive tape onto the terminal end of the battery cell.

[0092] Specifically, in the glue laminating method provided by the present application, the clamp cylinder 237 drives the second clamp 233 to move relative to the first clamp 231 to clamp the end of the tape, the moving component 22 drives the clamp component 23 and the cutter component 21 to move together to transfer the end of the tape to the glue laminating mechanism 1, the glue pressing cylinder 133 drives the pressing block 131 to press the end of the tape on the support rod 132, and then the clamp cylinder 237 drives the second clamp 233 away from the first clamp 231 to loosen the tape, and finally the glue laminating mechanism 1 abuts against the terminal end of the battery cell and rolls the tape onto the terminal end of the battery cell.

[0093] Regarding the above step S165: driving the adhesive sticking mechanism to abut against the terminal end of the battery cell and rolling the adhesive tape onto the terminal end of the battery cell, the contents may be different according to different application scenarios.

[0094] When it is necessary to glue a larger battery cell, the following steps are specifically included:

[0095] S171: The gluing mechanism moves close to the terminal end of the battery cell, and the gluing mechanism includes a gluing roller and a gluing assembly;

[0096] S172: driving the adhesive roller to press the end of the adhesive tape against the terminal end of the battery cell, and the adhesive roller can roll along the terminal end of the battery cell;

[0097] S173: releasing the end of the adhesive tape, rotating the battery cell and rolling a certain length of the adhesive tape onto the battery cell;

[0098] S174: driving the glue pressing assembly and the clamping plate assembly to clamp the adhesive tape, moving the glue cutting mechanism to between the clamping plate assembly and the glue sticking mechanism and cutting the adhesive tape;

[0099] S175: The glue pressing assembly releases the adhesive tape, and the adhesive tape rotates with the battery cell and is pressed onto the battery cell by the glue applying roller.

[0100] Specifically, the adhesive tape is only clamped by the glue pressing assembly 13, and the translation assembly 12 drives the glue pressing assembly 13 and the glue sticking assembly 11 to approach the needle winding mechanism 9; the glue sticking cylinder 112 drives the glue sticking roller 111 to press the end of the adhesive tape onto the terminal end of the battery cell. When pressing the end of the adhesive tape, the glue sticking roller bracket 119 can rotate relative to the glue sticking fixing seat 117 to stretch the spring 181, so that the glue sticking roller 111 rolls a distance along the surface of the battery cell and rolls the end of the adhesive tape onto the terminal end of the battery cell; then the moving assembly 22 drives the clamping plate assembly 23 and the cutter assembly 21 to move away from the glue sticking mechanism 1 to Figure 1 At the initial position shown, at the same time, the glue pressing cylinder 133 drives the pressing block 131 away from the support rod 132 to release the clamped end of the tape. At this time, the end of the tape is pressed against the terminal end of the battery cell by the glue roller 111.

[0101] After the needle winding mechanism 9 is rotated, the tape rotates with the needle winding mechanism 9 and is gradually pressed against the outer surface of the battery cell under the action of the adhesive roller 111. When a certain length of tape is wound around the outer surface of the battery cell, the needle winding mechanism 9 stops rotating. It should be noted that the certain length of tape mentioned here can be a length pre-calculated according to the size of the battery cell. Afterwards, the glue pressing cylinder 133 drives the pressing block 131 to approach the support rod 132 to clamp the tape, and the clamping plate cylinder 237 drives the second clamping plate 233 to move relative to the first clamping plate 231 to clamp the tape. At this time, the two ends of the tape are clamped by the glue sticking mechanism 1 and the glue feeding mechanism 2 respectively; the avoidance cylinder 241 moves the cutter 211 to between the glue sticking mechanism 1 and the glue feeding mechanism 2, and the cutter cylinder 218 drives the cutter 211 to cut the tape, thereby obtaining a certain length of tape; the glue pressing cylinder 133 drives the pressing block 131 away from the support rod 132 to loosen the tape, and the winding needle mechanism 9 continues to drive the battery cell to rotate and cooperates with the glue sticking roller 111 to roll the tail of the tape onto the outer surface of the battery cell; finally, the translation assembly 12 drives the glue pressing assembly 13 and the glue sticking assembly 11 away from the winding needle mechanism 9.

[0102] Another application scenario of the adhesive bonding method provided in the present application, that is, adhesive bonding for small batteries, includes the following steps:

[0103] S181: After driving the clamping plate assembly to be away from the adhesive tape mechanism by a certain distance, the clamping plate assembly is driven to clamp the adhesive tape;

[0104] S182: driving the adhesive cutting mechanism to move between the clamping plate assembly and the adhesive laminating mechanism and cut the adhesive tape;

[0105] S183: The glue sticking mechanism includes a glue sticking roller and a glue pressing assembly, and the glue sticking roller is driven to press the end of the adhesive tape against the terminal end of the battery cell;

[0106] S184: The adhesive pressing assembly releases the adhesive tape and rotates the battery cell, and the tail of the adhesive tape is pressed against the battery cell as the battery cell rotates.

[0107] Specifically, the adhesive tape is still only clamped by the glue pressing assembly 13, and the moving assembly 22 drives the clamping plate assembly 23 and the cutting knife assembly 21 to move a certain distance away from the glue sticking mechanism 1, so as to obtain an adhesive tape with a certain length. Then, the clamping plate cylinder 237 drives the second clamping plate 233 to move relative to the first clamping plate 231 to clamp the adhesive tape. At this time, the two ends of the adhesive tape are clamped by the glue pressing assembly 13 and the clamping plate assembly 23 respectively; the avoiding cylinder 241 moves the cutting knife 211 to between the glue sticking mechanism 1 and the glue feeding mechanism 2, and the cutting knife cylinder 218 drives the cutting knife 211 to cut the adhesive tape; the translation assembly 12 drives the glue pressing assembly 13 and the glue sticking assembly 11 to move closer to the winding needle mechanism 9; the glue sticking cylinder 112 drives the glue sticking roller 111 to cut the adhesive tape. The end of the tape is pressed against the terminal end of the battery cell. When holding the end of the tape, the glue roller bracket 119 can rotate relative to the glue fixing seat 117 to stretch the spring 181, so that the glue roller 111 rolls along the surface of the battery cell for a distance and rolls the end of the tape against the terminal end of the battery cell. The glue pressing cylinder 133 drives the pressing block 131 away from the support rod 132 to release the clamped end of the tape. At this time, the end of the tape is pressed against the terminal end of the battery cell by the glue roller 111. The needle winding mechanism 9 is turned, and the tail of the tape can be rolled against the outer surface of the battery cell with the rotation of the needle winding mechanism 9 and the glue roller 111.

[0108] It should be noted that the gluing device provided in the present application is installed on the mounting plate 8, and its various components can move along the first direction AA, the second direction BB, and the third direction CC. It is only a preferred scheme of the present application. Those skilled in the art can design a reasonable structural layout and moving direction according to the actual position of the battery cell terminal to achieve the gluing requirements for the battery cell terminal.
