[0032] Embodiment 1

[0033] Please refer to the attached Figure 1 , this embodiment provides a reel 10 recycling device for removing the waste pole pieces 20 and tapes on the surface of the reel 10, so as to recycle the reel 10. Among them, the tape attached to the reel 10 is a double-sided tape, preferably a combination of a single-sided tape and a double-sided tape. In this embodiment, the tape in the glue tearing process is set as a single-sided tape attached to the reel 10 along the length direction of the reel 10, and the double-sided tape is attached to the single-sided tape, and the double-sided tape is torn off by tearing the single-sided tape.

[0034] The invention comprises a support frame 1 for placing a reel 10, a placement portion 110 and a drive assembly 120 are arranged on the support frame 1, and the drive assembly 120 is arranged on one side of the placement portion 110 to drive the reel 10 to rotate. Specifically, the support frame 1 comprises a first support plate and a second support plate, the first support plate and the second support plate are arranged oppositely, and the placement portion 110 is arranged at the top of the first support plate and the second support plate respectively. The placement portion 110 is used to place the end of the reel 10, and the placement portion 110 can be in a "V" shape. The slot at the end of the reel 10 is clamped on the placement portion 110 by a V-bracket, and the reel 10 is limited to prevent it from falling in subsequent work. The drive assembly 120 is used to drive the reel 10 to rotate. It can be understood that the drive assembly 120 can be a combination of a motor, a reducer, a coupling and other equipment, so as to drive the reel 10 to rotate. In some embodiments, a color mark sensor can also be arranged on the support frame 1, and the rotation position of the reel 10 is positioned by the color mark sensor.

[0035] The glue peeling module 2 is arranged on one side of the placement part 110. The glue peeling module 2 includes a clamping member 210 and a first moving assembly 220. The first moving assembly 220 is connected to the clamping member 210 in a transmission manner to drive the clamping member 210 to move along the length direction of the reel 10. The clamping member 210 can be a clamping claw 211, a cylinder, a manipulator, etc., which is used to clamp the tape on the surface of the reel 10. The first moving assembly 220 can be a combination of a linear guide, a drive motor and a ball screw, or a combination of a linear guide and a hydraulic cylinder or a pneumatic cylinder. This embodiment does not limit this, and it only needs to drive the clamping member 210 to move. Exemplarily, the first moving assembly 220 is a combination of a linear guide, a drive motor and a ball screw. The linear guide is arranged on one side of the screw, and a movable block is arranged on the screw. The clamping member 210 is arranged on the movable block, and the movable block is driven to move by the rotation of the motor.

[0036] It is understandable that a positioning sensor can also be provided on the adhesive stripping module 2 to locate the position of the single-sided adhesive on the roll 10, thereby improving the accuracy of adhesive stripping and the degree of automation of the equipment. Among them, it can be visual positioning, such as CCD.

[0037] During use, the reel 10 is first placed on the placement portion 110 of the bracket. At this time, the drive component 120 drives the reel 10 to rotate, and the waste electrode 20 on the reel sags under the action of gravity and then falls, and the waste electrode 20 on the reel 10 is removed. Subsequently, the clamping member 210 clamps the single-sided adhesive on the reel 10. After the clamping is completed, the first moving component 220 drives the clamping member 210 to move, and then the single-sided adhesive and double-sided adhesive on the surface of the reel 10 are torn off. The reel 10 enters the next process, and the reel 10 after recycling can be directly loaded, or placed on the assembly line for storage or centralized storage.

[0038] This embodiment can remove waste materials on the reel 10 and recycle the reel 10 by setting a support frame 1 and a glue tearing module 2. The reel 10 is set on the support frame 1, and the driving component 120 drives the reel 10 to rotate, and the pole piece 20 is used to fall off by itself due to its own weight. After the falling off is completed, the tape on the surface of the reel 10 is exposed. At this time, the tape can be clamped by the clamping member 210 and the clamping member 210 can be driven to move by the first moving component 220 to complete the tearing of the tape. The reel 10 recovery device of this embodiment can automatically recycle the reel 10 by first removing the waste pole piece 20 and then tearing off the tape. Compared with the existing cleaning method, the reel 10 recovery device of this embodiment is automated and has high recovery efficiency, which improves production efficiency, reduces manpower requirements, and reduces safety risks.

[0039] Example 2

[0040] The difference between Example 2 and Example 1 is that the present embodiment further optimizes the reel 10 recovery device, such as Figures 2-5 As shown, a rolling assembly 130 is also provided on the support frame 1, and the rolling assembly 130 is arranged on one side of the placement portion 110. The rolling assembly 130 includes at least a first pressing roller 131 and a second pressing roller 132, and the first pressing roller 131 and the second pressing roller 132 are arranged opposite to each other, and a gap is left between the first pressing roller 131 and the second pressing roller 132 to form a rolling channel. Among them, the rolling assembly 130 is arranged at the bottom of the support frame 1, and is arranged along the direction of the pole piece 20 of the reel 10 falling off. It can be understood that the rolling assembly 130 can also include a third pressing roller, a fourth pressing roller, etc., and this embodiment does not specifically limit the number. Exemplarily, a reel 10 is provided on the placement portion 110 of the support frame 1, and a first pressing roller 131 and a second pressing roller 132 are provided at the bottom of the reel 10. At this time, the reel 10 rotates, and the pole piece 20 falls off due to its own weight and enters the rolling channel between the first pressing roller 131 and the second pressing roller 132, so that the pole piece 20 is guided so that the falling positions of the discarded pole piece 20 are consistent, thereby keeping the work station clean and tidy.

[0041] In some embodiments, the rolling assembly 130 further includes a first driving member 133, which is in transmission connection with the first pressing roller 131 to drive the first pressing roller 131 to rotate. The first driving member 133 may be a combination of a motor and a reducer, a motor and a rotating shaft, etc., and the motor is used to drive the first pressing roller 131 to rotate. When the pole piece 20 enters the rolling channel or falls above the rolling channel, the first pressing roller 131 is driven to rotate by the first driving member 133, thereby driving the pole piece 20 to move, and the drive assembly 120 drives the reel 10 to rotate, thereby improving the shedding efficiency of the pole piece 20, and preventing the pole piece 20 from being difficult to fall off on the reel 10 due to its own weight due to high viscosity.

[0042] In some embodiments, the rolling assembly 130 further includes a second driving member 134, which is drivingly connected to the second pressing roller 132 to drive the second pressing roller 132 to approach or move away from the first pressing roller 131. The second driving member 134 can be a cylinder, or a combination of a motor, a lead screw, and a guide rail, or a rack and pinion, etc. The second driving member 134 can drive the second pressing roller 132 to move laterally, reducing or expanding the size of the rolling channel between the first pressing roller 131 and the second pressing roller 132. This setting enables the rolling assembly 130 to be applicable to electrode foils 20 of different thicknesses. At the same time, after the electrode foil 20 enters the rolling channel, the second driving member 134 is used to drive the second pressing roller 132 to press it, increasing the frictional force, so that the electrode foil 20 is more likely to move along with the rotation of the first pressing roller 131, improving the peeling efficiency.

[0043] In some embodiments, the first pressing roller 131 and / or the second pressing roller 132 is a rubber roller. Specifically, the first pressing roller 131 is a rubber roller, or the second pressing roller 132 is a rubber roller, or both the first pressing roller 131 and the second pressing roller 132 are rubber rollers. The rubber roller can roll the electrode foil 20 well, and its cost is low and it is not easy to pollute the environment.

[0044] In some embodiments, a waste bin 140 for placing the waste electrode foil 20 is further included, and the waste bin 140 is arranged on one side of the support frame 1. Among them, the waste bin 140 is arranged at the bottom of the support frame 1. The support frame 1 is sequentially provided with a placing portion 110, a rolling assembly 130, and a waste bin 140 from top to bottom. When the reel 10 is placed on the placing portion 110, the rolling assembly 130 is used to guide the electrode foil 20 so that it enters the waste bin 140, keeping the working station clean and facilitating subsequent recycling.

[0045] In some embodiments, the driving assembly 120 includes a third driving member and an air shaft 121. The air shaft 121 is arranged on one side of the placing portion 110, and the third driving member is drivingly connected to the air shaft 121 to drive the air shaft 121 to rotate. Among them, the driving assemblies 120 are arranged at both ends of the support frame 1. When the reel 10 is placed on the placing portion 110, the air shaft 121 expands. The third driving member can be a motor, and the motor drives the air shaft 121 to rotate, thereby driving the reel 10 to rotate.

[0046] In some embodiments, the glue tearing module 2 further includes a second moving component 230, which is in transmission connection with the first moving component 220. The clamping member 210 is arranged on the second moving component 230 to drive the clamping member 210 to approach or move away from the reel 10. Specifically, the second moving component 230 can be a linear moving module, a motor plus a lead screw guide rail, a rack and pinion, etc., to drive the clamping member 210 to move through the second moving component 230. Exemplarily, the first moving component 220 moves along the length direction of the reel 10, and the moving direction of the second moving component 230 is perpendicular to that of the first moving component 220. During use, visual positioning can be used to position the end position of the single-sided adhesive on the reel 10. The first moving component 220 moves to the end of the single-sided adhesive, and the second moving component 230 drives the clamping member 210 to move near the end of the single-sided adhesive. The clamping member 210 clamps the single-sided adhesive to tear the glue.

[0047] In some embodiments, the clamping member 210 includes a clamping jaw 211 and a fourth driving member 212. The fourth driving member 212 is in transmission connection with the clamping jaw 211 to drive the clamping jaw 211 to rotate. The fourth driving component 120 can be a motor, a rotary cylinder, etc. The motor drives the clamping jaw 211 to rotate, so as to perform rotary glue tearing on the single-sided adhesive, as Figure 5 shown. Rotary glue tearing is beneficial to the removal of the adhesive tape after glue tearing, and compared with horizontal glue tearing, it is not easy to break the adhesive tape during glue tearing, improving the stability of glue tearing.

[0048] Preferably, as Figure 4 shown, the reel 10 is further provided with glue pasting grooves, namely a horizontal glue pasting groove and an annular groove. The single-sided adhesive passes through the annular groove through the horizontal groove. When tearing the glue of the reel 10, only need to move the clamping jaw 211 to the annular groove to clamp the single-sided adhesive, improving the glue tearing efficiency.

[0049] Embodiment 3

[0050] The difference between Embodiment 3 and Embodiment 1 is that in this embodiment, the reel 10 recycling device is further optimized. As Figure 1 shown, it further includes a feeding module, which is arranged on one side of the support frame 1 to place the reel 10 on the support frame 1. Among them, the feeding module can be a robotic arm, an AGV feeding trolley, etc. Exemplarily, the feeding module is an AGV feeding trolley. The AGV feeding trolley can automatically identify the loading and unloading stations depending on the labels pasted on the fixed points of the reel 10 in advance. After moving to the loading and unloading station, the unloading arm clamps the empty reel 10, the air shaft 121 is loosened and retracted, and the AGV feeding trolley fixes the empty reel 10 to perform loading on the reel 10.

[0051] The reel glue preparation device of this embodiment can realize automatic loading and unloading of the reel, improve the recycling efficiency, and improve the automation degree of the equipment.
