[0037] The embodiment of the present application proposes a glue peeling mechanism to solve the problem that currently defective batteries need to be manually disassembled, resulting in low efficiency of battery disassembly. The glue peeling mechanism can be used, but not limited to, to peel off the sealing tape on the battery, and can also be used to peel off tape to be peeled on other structures.

[0038] The glue peeling mechanism of the embodiment of the present application is described in detail below.

[0039] According to some embodiments of this application, please refer to Figure 1 , Figure 2 and Figure 3 The glue peeling mechanism 100 includes a glue sticking assembly 10 and a glue peeling assembly 30. The glue sticking assembly 10 includes a glue sticking part 11 for obtaining the adhesive tape L, and the glue sticking part 11 is movably arranged. The glue peeling assembly 30 includes a glue peeling part 31 movably arranged relative to the glue sticking assembly 10. When the glue sticking part 11 moves, it can deliver the obtained adhesive tape L to the glue peeling part 31 for fixing. When the glue sticking part 11 moves away from the glue peeling part 31, it can perform a glue sticking operation of attaching the adhesive tape L fixed by the glue peeling part 31 to an external structure. When the glue peeling part 31 moves, it can perform a glue peeling operation of tearing off the fixed adhesive tape L.

[0040] The adhesive member 11 is used to obtain the adhesive tape L, and can attach the obtained adhesive tape L to an external structure, which can be, but not limited to, an adhesive rod, an adhesive claw, and other components. The external structure can be, but not limited to, a battery cell G to be disassembled, and the adhesive member 11 can attach the obtained adhesive tape L to the sealing roll tape G1 of the battery cell G. The adhesive member 11 can obtain the adhesive tape L by clamping, adsorption, and other methods. The adhesive tape L can be delivered to the adhesive member 11 under manual operation and obtained by the adhesive member 11, or it can be obtained by the adhesive member 11 itself during movement.

[0041] The moving track of the adhesive member 11 can be a straight track, a zigzag track, an arc track, etc. For example, for a wound cell G, when the sealing tape G1 is located in the arc-shaped circumference area, the adhesive member 11 can move along the arc track; when the sealing tape G1 is located in the plane circumference area, the adhesive member 11 can move along a straight track. Figure 2 and Figure 3 As shown, the sealing tape G1 is usually bent and pasted on two adjacent side surfaces. At this time, the adhesive member 11 can move along the adjacent side surfaces of the battery cell G in a zigzag trajectory, and the tape L is pasted on the sealing tape G1.

[0042] Generally, the glue peeling mechanism 100 includes a glue driving assembly 20, which is connected to the glue piece 11 and drives the glue piece 11 to move. The construction of the glue driving assembly 20 is flexibly designed by those skilled in the art according to the moving trajectory of the glue piece 11. For example, if the moving trajectory of the glue piece 11 is a straight line trajectory, the glue driving assembly 20 may include a linear module, which can drive the glue piece 11 to move along its own moving direction.

[0043] The peeling piece 31 can fix the adhesive tape L, and the fixing method can be adsorption fixing, clamping fixing, bonding fixing, etc. When the peeling piece 31 is bonded and fixed to the adhesive tape L, the adhesive tape L itself can be used to bond to the peeling piece 31.

[0044] Typically, the glue peeling assembly 30 also includes a glue peeling driving assembly, which is connected to the glue peeling piece 31 and is used to drive the glue peeling piece 31 to move. The glue peeling driving assembly may include a telescopic cylinder, a linear motor, a rotary motor, etc., and the glue peeling driving assembly may be used to drive the glue peeling piece 31 to move along a linear trajectory or a curved trajectory.

[0045] It can be understood that the adhesive peeling member 31 has a glue fixing position and a glue peeling position during the movement. When the adhesive peeling member 31 is at the glue fixing position, it can receive the adhesive tape L delivered by the adhesive sticking member 11 and fix the adhesive tape L. When the adhesive peeling member 31 moves from the glue fixing position to the glue peeling position, the adhesive peeling member 31 performs the glue peeling operation and drives the fixed adhesive tape L to move, thereby causing the adhesive tape L to separate from the external structure.

[0046] In actual application, the glue sticking part 11 obtains the tape L and moves toward the glue tearing part 31 to deliver one end of the carried tape L to the glue tearing part 31, and the glue tearing part 31 fixes the tape L. Then, the glue sticking part 11 moves away from the glue tearing part 31, performs the glue sticking operation during the movement, and sticks the carried tape L to the tail sealing roll tape G1 of the battery cell G. At this time, a part of the tape L is fixed to the glue tearing part 31, and the other part is attached to the tail sealing roll tape G1. After the glue sticking part 11 is in place, the glue tearing part 31 moves and drives one end of the fixed tape L to move, so that the part of the tape L attached to the tail sealing roll tape G1 drives the tail sealing roll tape G1 to be torn off from the battery cell G. In this way, the glue tearing mechanism 100 can be used to realize the automatic tearing off of the tail sealing roll tape G1 of the battery cell G without manual operation, which can improve the disassembly efficiency of the battery cell G.

[0047] It should be noted that the adhesive tape L carried by the adhesive sticking member 11 is usually a single-sided adhesive tape L. When the adhesive sticking member 11 obtains the adhesive tape L, it can be fixed to the non-adhesive surface of the adhesive tape L. When the adhesive sticking member 11 performs the adhesive sticking operation, the adhesive surface of the adhesive tape L faces the surface to be bonded of the external structure. In addition, when the adhesive sticking member 11 moves toward the adhesive tearing member 31, the adhesive surface of the carried adhesive tape L can be directed toward the adhesive tearing member 31, so that the adhesive tape L is bonded and fixed to the adhesive tearing member 31.

[0048] In some embodiments, please refer to Figure 1 The adhesive component 10 also includes a mounting seat 12, which can move independently along the first direction X and the second direction Y. The adhesive component 11 is arranged on the mounting seat 12 and can be rotatably arranged around a preset axis F relative to the mounting seat 12. The preset axis F, the first direction X and the second direction Y are not coplanar and intersect each other.

[0049] The adhesive member 11 is disposed on the adhesive driving assembly 20 via the mounting seat 12, and the adhesive driving assembly 20 is used to drive the mounting seat 12 to move along the first direction X and the second direction Y. In practical applications, the first direction X can be a horizontal direction, the second direction Y can be a vertical direction, and the preset axis F can be a horizontal axis that is orthogonal to the first direction X and the second direction Y.

[0050] exist Figure 1 In the illustrated embodiment, the glue application drive assembly 20 includes a translation drive 21 and a lifting drive 22. The translation drive 21 is used to drive the mounting seat 12 to translate along the first direction X, thereby driving the glue application member 11 to translate. The translation drive 21 may include, but is not limited to, a translation linear module. The lifting drive 22 is used to drive the mounting seat 12 to move up and down along the second direction Y, thereby driving the glue application member 11 to move up and down. The lifting drive 22 may include, but is not limited to, a lifting linear module.

[0051] Typically, the adhesive component 10 further includes a rotation driving member 13, which may be, but is not limited to, disposed on the mounting seat 12, and is in transmission connection with the adhesive component 11, and can drive the adhesive component 11 to rotate relative to the mounting seat 12 around a preset axis F. Specifically, the mounting seat 12 may be provided with a rotating shaft, the adhesive component 11 is fixed to the rotating shaft, and the rotation driving member 13 is connected to the rotating shaft and can drive the rotating shaft to rotate.

[0052] In practical applications, such as Figure 2 and Figure 3 As shown, the sealing tape G1 is usually bent and pasted on two adjacent sides of the battery cell G. When the adhesive member 11 moves along the first direction X on one of the sides and switches to the second direction Y on the other side, the adhesive member 11 will smooth the tape L carried along its moving track on the sealing tape G1. In this process, when the adhesive member 11 switches from the first direction X to the second direction Y, in order to keep the position of the adhesive member 11 acting on the tape L unchanged, the adhesive member 11 rotates at a set angle. Figure 2 In the illustrated embodiment, the adhesive member 11 can be rotated 90 degrees.

[0053] Of course, if the sealing tape G1 is only arranged on one side of the battery cell G, then in actual application, the adhesive component 11 can also move only under the action of the adhesive driving assembly 20. As for whether the adhesive component 11 moves along the first direction X or the second direction Y, it can be flexibly designed according to the actual arrangement orientation of the sealing tape G1.

[0054] In this way, the glue sticking member 11 can be moved and rotated under the action of the rotating driving member 13 and the bonding driving assembly, and can be adapted to tearing off the tail-sealing roll tape G1 with various arrangements, and the tape L can cover a larger area of ​​the tail-sealing roll tape G1. The glue tearing member 31 can tear off the tail-sealing roll tape G1 smoothly, thereby improving the glue tearing effect of the glue tearing mechanism 100.

[0055] It should be noted that in other embodiments, the adhesive member 11 may also move only in the first direction X and the second direction Y without rotating. In some embodiments, the adhesive member 11 is configured to be rotatable, which can keep the pressing surface (such as the adsorption surface described below) of the adhesive member 11 that presses the tape L in contact with the tape L. On the other hand, in actual design, the pressing surface can be configured to have a larger area, while the other surfaces intersecting with the pressing surface have a smaller area, which not only has a better pressing effect on the tape L, but also can reduce the volume of the adhesive member 11. Furthermore, the rotatable adhesive member 11 can also be adapted to attach the tape L to the curved end-sealing roll tape G1.

[0056] In some embodiments, please refer to Figure 2 and Figure 3 The adhesive member 11 has an adsorption end 11 a, and the adsorption end 11 a is used for adsorbing the adhesive tape.

[0057] The adsorption end 11a is usually but not limited to a negative pressure adsorption tape L. Optionally, an adsorption gas path is provided at the adsorption end 11a, and the adsorption gas path is used to communicate with a negative pressure source.

[0058] In actual application, the end of the adhesive tape L is adsorbed on the adsorption end 11a of the adhesive member 11. Figure 2 As shown, the suction end 11a of the adhesive sticking member 11 first delivers the head of the adhesive tape L to the adhesive tearing member 31 for fixing, and then moves and smoothes and presses the remaining part of the adhesive tape L fixed by the adhesive tearing member 31 onto the end-sealing roll adhesive tape G1. It should be noted that during the process of the suction end 11a of the adhesive sticking member 11 moving and smoothing and pressing the adhesive tape L, the suction end 11a can keep sucking the adhesive tape L or not, as long as the adhesive tape L can be stuck on the external structure.

[0059] At this time, the adhesive member 11 obtains the adhesive tape L by adsorption, which has a simple structure and is easy to implement, and does not occupy too much space.

[0060] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 3 The adhesive laminating assembly 10 further includes a material tray 14 and a cutter 15 . The material tray 14 is used for unwinding the adhesive tape L, and the cutter 15 is used for cutting the adhesive tape L unwinding from the material tray 14 .

[0061] Generally, the material tray 14 includes a rotatable material barrel, on which the adhesive tape L can be wound, and the material barrel can unwind the adhesive tape L when rotating. The adhesive applying member 11 can absorb the material head of the adhesive tape roll on the material tray 14, and the adhesive applying member 11 can pull the adhesive tape L unwinding from the material tray 14 during the movement. When a certain length of the adhesive tape L is pulled out, the cutter 15 can cut the adhesive tape L.

[0062] The cutter 15 can cut the tape L at the tape L between the glue sticking part 11 and the material tray 14 before the glue sticking part 11 performs the glue sticking operation. The cutter 15 can also cut the tape L at the tape L between the glue sticking part 11 and the material tray 14 after the glue sticking part 11 performs the glue sticking operation. The cutter 15 can also cut the tape L at the tape L on the side of the glue sticking part 11 away from the material tray 14 after the glue sticking part 11 performs the glue sticking operation. Regarding the specific structure of the cutter 15, those skilled in the art can make conventional settings.

[0063] At this time, the adhesive tape L can be continuously provided to the adhesive member 11 through the material tray 14 , and the adhesive tape L can be cut by the cutter 15 , so that the adhesive tape stripping mechanism 100 can perform a continuous adhesive tape stripping operation.

[0064] In some embodiments, a receiving portion is disposed on the adhesive member 11 , and the cutter 15 is disposed in the receiving portion and can extend or retract relative to the receiving portion.

[0065] The receiving portion can be a structure with a receiving space such as a receiving groove or a receiving hole. The cutter 15 is arranged in the receiving portion and can extend or retract relative to the receiving portion. Specifically, the glue laminating assembly 10 also includes a cutting drive 16, which can drive the cutter 15 to move or rotate, thereby making the cutter 15 extend or retract back to the receiving portion. For example, the cutting drive 16 includes a cutting cylinder, which is arranged on the mounting seat 12 and is located outside the receiving portion, and the telescopic end of the cutting cylinder can penetrate into the receiving portion and connect with the cutter 15.

[0066] In actual application, when it is necessary to cut the adhesive tape L, the cutter 15 extends from the receiving portion. When it is not necessary to cut the adhesive tape L, the cutter 15 retracts into the receiving portion, which can prevent the cutter 15 from damaging the adhesive tape L and will not interfere with the adhesive application.

[0067] In some embodiments, reference Figure 2 and Figure 3 The adhesive member 11 has an adsorption end 11a, and a receiving portion is arranged at the adsorption end 11a. The adsorption end 11a has a first surface m1 and a second surface m2 arranged to intersect each other. An opening is arranged on the first surface m1, and the cutter 15 enters and exits the receiving portion through the opening. The second surface m2 is constructed as an adsorption surface.

[0068] The adsorption surface may be based on the negative pressure adsorption tape L. Adsorption holes connected to the negative pressure source may be provided on the adsorption surface.

[0069] In actual work, combined with Figure 2 and Figure 3 , the adsorption surface adsorbs the tape L, the glue sticking member 11 moves toward the glue tearing member 31, and sends the adsorbed tape L to the glue tearing member 31, and then the glue sticking member 11 moves along the first direction X away from the glue tearing member 31, so that the adsorption surface smoothes and presses the tape L on the sealing roll tape G1 on one of the side surfaces of the battery cell G, and then the rotating driving member 13 drives the glue sticking member 11 to rotate a certain angle, and the glue sticking member 11 moves along the second direction Y, so that the adsorption surface smoothes and presses the tape L on the sealing roll tape G1 on the other intersecting side surface of the battery cell G. Then, the rotating driving member 13 drives the adhesive member 11 to reverse a certain angle, so that the opening on the first surface m1 is opposite to the tape L, and the adsorption surface adsorbs the tape L, and the cutter 15 extends out of the accommodating portion through the opening and cuts the tape L, so that the tape L adsorbed on the adsorption surface is separated from the tape L adhered to the battery cell G, and the part of the tape L adsorbed on the adsorption surface is reused as the material head of the tape L on the material tray 14.

[0070] At this time, one end of the cut tape L can be directly adsorbed on the adsorption end 11a as the material head of the tape L roll, which simplifies the process of the adsorption end 11a obtaining the material head of the tape L and improves the adhesive peeling efficiency of the adhesive peeling mechanism 100.

[0071] In some embodiments, reference Figure 2 and Figure 3 The adhesive peeling member 31 includes an adhesive peeling jaw for fixing the adhesive tape L. The adhesive peeling jaw can clamp the material head of the adhesive tape L conveyed by the adhesive sticking member 11, and then fix the adhesive tape L. The specific structure of the adhesive peeling jaw can be conventionally set by those skilled in the art. At this time, the adhesive peeling member 31 uses the adhesive peeling jaw to fix the material head of the adhesive tape L, and the structure is simple and easy to implement.

[0072] In addition, the embodiment of the present application further provides a battery cell disassembling device, including the glue peeling mechanism 100 of any of the above embodiments, wherein the glue sticking member 11 of the glue peeling mechanism 100 is used to stick the adhesive tape L to the tail sealing roll tape G1 of the battery cell G when performing the glue sticking operation, and the glue peeling member 31 is used to tear the tail sealing roll tape G1 attached by the adhesive tape L from the battery cell G when performing the glue peeling operation. The battery cell disassembling device includes all the above beneficial effects.

[0073] In some embodiments, the battery cell disassembling device further includes a diaphragm winding mechanism 200, which is used to wind up the diaphragm of the battery cell G from which the sealing tape G1 has been torn off. In practical applications, when the sealing tape G1 on the battery cell G is torn off, the diaphragm on the battery cell G can be continuously separated by rotating the battery cell G. At this time, the diaphragm winding mechanism 200 can be used to wind up the separated diaphragm.

[0074] The membrane rewinding mechanism 200 may include a rewinding roller, which is rotatable and can rewind the membrane when rotating. Of course, the membrane rewinding mechanism 200 may also adopt the scheme in the following embodiments.

[0075] In some embodiments, reference Figure 4 The membrane winding mechanism 200 includes a rotating platform 201 and a membrane clamping jaw 202, and the membrane clamping jaw 202 is disposed on the rotating platform 201. The rotating platform 201 can drive the membrane clamping jaw 202 to rotate, so that the membrane clamped by the membrane clamping jaw 202 is rolled up on the outer periphery of the membrane clamping jaw 202.

[0076] The rotating platform 201 can rotate under the drive of a power source such as a rotating motor. The diaphragm clamp 202 is arranged on the rotating platform 201, and can clamp the end of the diaphragm. When the rotating platform 201 rotates, the diaphragm clamp 202 rotates accordingly, so that the diaphragm clamped by the diaphragm clamp 202 is wound around the outer periphery of the diaphragm clamp 202, thereby realizing the winding of the diaphragm.

[0077] The specific structure of the diaphragm clamping jaw 202 can be conventionally configured by a person skilled in the art. For example, the diaphragm clamping jaw 202 includes two clamping plates 202a arranged opposite to each other and a clamping motor, and the clamping motor can drive the two clamping plates 202a to move relative to each other, so that the two clamping plates 202a clamp or release the diaphragm. The two clamping plates 202a can move relative to each other in a direction perpendicular to the rotation direction of the rotating platform 201.

[0078] Further to the embodiment, continue to refer to Figure 4 The diaphragm winding mechanism 200 further includes a push plate 203 , which is movably arranged in a direction parallel to the rotation axis of the rotating platform 201 , and can push the diaphragm wound on the diaphragm clamp 202 to leave the diaphragm clamp 202 during movement.

[0079] Specifically, the push plate 203 can be movably arranged on the rotating platform 201 along the rotation axis of the rotating platform 201. A push plate driving member 204 can be arranged on the rotating platform 201, and the push plate 203 can be automatically pushed to move by the driving member. A guide structure 205 (such as a guide column, a guide hole, etc.) can also be arranged on the rotating platform 201, and the push plate 203 moves along the guide structure 205. The orthographic projection of the push plate 203 along the rotation axis can be arranged around the orthographic projection of the diaphragm clamping jaw 202, so that the push plate 203 can be in contact with the annular surface of the diaphragm roll wound on the diaphragm clamping jaw 202.

[0080] In actual application, when the membrane is rolled into place, the membrane clamping jaws 202 can release the clamped end of the membrane, and then the movable push plate 203 pushes the membrane roll from the membrane clamping jaws 202 to remove the membrane roll.

[0081] In a specific embodiment of the present application, the battery cell disassembly device includes a glue peeling mechanism 100 and a diaphragm winding mechanism 200. The glue peeling mechanism 100 includes a glue sticking piece 11, a mounting seat 12, a rotating driving piece 13, a glue sticking driving assembly 20, a cutter 15, a material tray 14 and a glue peeling jaw. The glue sticking piece 11 is rotatably arranged on the mounting seat 12. The rotating driving piece 13 is used to drive the glue sticking piece 11 to rotate. The glue sticking driving assembly 20 is used to drive the mounting seat 12 to move in a first direction X and a second direction Y. The glue sticking piece 11 has an adsorption end 11a, which can adsorb the negative pressure adsorption tape L. The cutter 15 is arranged on the receiving portion of the adsorption end 11a and can be extended or retracted back to the receiving portion. The glue peeling jaw is movably arranged.

[0082] Combination Figure 2 and Figure 3It is understood that the battery cell disassembly device is used to disassemble the battery cell G, and the same sealing tape G1 is provided on the first side surface and the second side surface of the battery cell G. The working process of the battery cell disassembly device is roughly as follows: the adsorption end 11a of the adhesive sticking member 11 adsorbs the material head of the adhesive tape L unwound from the material tray 14, and the adhesive sticking driving assembly 20 drives the mounting seat 12 to move along the first direction X so that the adhesive sticking member 11 sends the material head of the adhesive tape L adsorbed by its adsorption end 11a to the adhesive tearing clamp for clamping and fixing. Then, the glue-applying driving assembly 20 drives the mounting seat 12 to move in the opposite direction along the first direction X, and its adsorption end 11a smoothes the pressing tape L on the sealing tape G1 on the first side; then, the rotating driving member 13 drives the glue-applying member 11 to rotate forward, so that the adsorption end 11a keeps the pressing tape L on the sealing tape G1 on the second side; then, the adsorption end 11a negatively adsorbs the tape L, and the rotating driving member 13 drives the glue-applying member 11 to rotate in the opposite direction, so that the opening on the adsorption end 11a faces the tape L, and the cutter 15 extends out of the receiving portion through the opening and cuts off the tape L; then, the glue-tearing member 31 drives the fixed tape L to move, and tears the sealing tape G1 off the battery cell G to expose the diaphragm. The diaphragm winding mechanism 200 winds up the diaphragm separated from the battery cell G.
