Description

Technical Field

[0001] This invention relates to the field of waste lithium battery recycling technology, specifically to a reverse precision separation and dismantling device and method for battery cell rolls. Background Technology

[0002] With the booming development of the new energy vehicle industry in recent years, a large number of lithium-ion power batteries have been produced, manufactured and used. The service life of lithium-ion power batteries is generally 5 to 8 years, so more and more lithium-ion power batteries will face retirement.

[0003] Because lithium-ion power batteries contain valuable metals such as nickel, cobalt, manganese, and lithium, they have high recycling and regeneration value. Waste batteries are called "urban mines." Most existing methods for dismantling lithium-ion power batteries rely on manual dismantling, which requires a large amount of manpower, occupies a large area, has a low degree of automation, and is dangerous and causes significant environmental pollution. These methods can no longer meet the demand for large-scale recycling and dismantling. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a reverse precision separation and dismantling device and method for battery cell rolls, so as to solve the problem that most of the current dismantling of stacked battery cell rolls is done manually, which is inefficient and poses a risk to personal safety.

The dewinding mechanism has an air-blowing brush connected to an air source via a pipeline. The air from the air-blowing brush flows towards the cut end of the surface diaphragm in the battery cell roll clamped by the dewinding mechanism, causing the cut end of the surface diaphragm to open and be peeled off by the diaphragm. The mechanism includes a gripping and suction system; a negative electrode receiving mechanism is installed on the frame between the limiting and blocking mechanism and the diaphragm peeling mechanism; a diaphragm separation mechanism, a secondary diaphragm cutting mechanism, and a positive electrode receiving mechanism are sequentially arranged between the diaphragm peeling mechanism and the film pulling mechanism; there are two diaphragm separation mechanisms, arranged in an upper and lower relative configuration; the lower diaphragm separation mechanism is fixed to the frame, and the upper diaphragm separation mechanism is fixed to the frame via a sixth lifting mechanism; there are also two diaphragm secondary cutting mechanisms, arranged in an upper and lower relative configuration; the lower diaphragm secondary cutting mechanism is fixed to the frame, and the upper diaphragm secondary cutting mechanism is fixed to the frame via a seventh lifting mechanism.

The third servo motor is fixed on the transmission mechanism, the main shaft of the third servo motor is fixed to the input shaft of the transmission mechanism, and the output shaft of the transmission mechanism is fixed to the clamping block.

[0010] Furthermore, the negative electrode receiving mechanism includes: a first electric roller and a third Y-axis moving mechanism. The first electric roller and the third Y-axis moving mechanism are fixedly connected to the frame. The rotation axis of the first electric roller is distributed along the X-axis. A first passive roller parallel to the first electric roller is rotatably connected to the third Y-axis moving mechanism. Under the action of the third Y-axis moving mechanism, the first passive roller moves closer to and further away from the first electric roller in the Y-axis direction.

[0011] Furthermore, the membrane pulling mechanism includes: a first Y-axis moving mechanism fixed on the frame, with at least one second pneumatic gripper fixed side by side on the first Y-axis moving mechanism; the diaphragm peeling mechanism includes: a base fixed on the frame, a first lifting mechanism fixed below the base, a mounting plate fixed above the base and connected to the first lifting mechanism, a buffer plate and an air nozzle assembly on the side of the mounting plate near the limiting blocking mechanism, and at least one first pneumatic gripper below the mounting plate; a ninth lifting mechanism fixed on the base between the mounting plate and the limiting blocking mechanism, a diaphragm release plate fixed on the ninth lifting mechanism, a transition roller rotatably mounted on the side of the diaphragm release plate near the limiting blocking mechanism, the rotation axis of the transition roller being distributed along the X-axis, and an avoidance notch on the diaphragm release plate corresponding to each second pneumatic gripper.

[0012] Furthermore, the diaphragm separation mechanism includes: a base fixed to the frame or the sixth lifting mechanism; a fifth lifting mechanism fixed on the side of the base away from the transmission surface; a film suction assembly fixed to the fifth lifting mechanism and distributed along the X-axis direction on the side of the base near the transmission surface; a fourth Y-axis moving mechanism fixed on the side of the base near the transmission surface; a second passive roller and a second electric roller respectively arranged on both sides of the film suction assembly; the second passive roller is rotatably connected to the fourth Y-axis moving mechanism; and the second electric roller is fixed to the base.

[0015] Based on the above technical solution, the present invention also provides a method for reverse precision separation and dismantling of battery cell rolls, using the aforementioned reverse precision separation and dismantling equipment, comprising the following steps: S100. Place the battery cell roll on the limiting and blocking mechanism, and the limiting and blocking mechanism limits the battery cell roll in the X and Y axis directions; S200, the diaphragm primary cutting mechanism cuts the diaphragm on the surface of the battery cell roll that is limited by the limiting and blocking mechanism; S300: After the diaphragm cutting mechanism cuts the diaphragm on the surface of the battery cell roll, the lifting mechanism lifts the battery cell roll in the Z-axis direction. S400, the anti-winding mechanism clamps the battery cell roll on the lifting mechanism and transfers it to the diaphragm peeling mechanism. Then, the gas in the air source enters the blowing brush through the pipeline and flows out through the blowing brush. The gas flowing out of the blowing brush flows to the break point of the surface diaphragm in the battery cell roll clamped by the anti-winding mechanism. The airflow causes the end of the surface diaphragm break point to be blown open. The anti-winding mechanism then rotates the battery cell roll in the opposite direction to unwind the battery cell roll, allowing the negative terminal to fall into the negative electrode receiving mechanism in a natural hanging manner. The unwound diaphragm + positive electrode + diaphragm is gripped and sucked by the diaphragm peeling mechanism. S500, the membrane pulling mechanism first clamps the membrane + positive electrode + membrane gripped by the membrane peeling mechanism and resets it. During the reset process, the membrane + positive electrode + membrane passes through two membrane separation mechanisms distributed above and below, two membrane secondary cutting mechanisms distributed above and below, and the positive electrode receiving mechanism. S600, the seventh lifting mechanism controls the upper diaphragm secondary cutting mechanism to move downward, and cooperates with the lower diaphragm secondary cutting mechanism to clamp the diaphragm + positive electrode + diaphragm, so as to cut the diaphragm on the upper and lower surfaces of the positive electrode respectively. S700, the sixth lifting mechanism controls the upper diaphragm separation mechanism of the two diaphragm separation mechanisms to move downward, the two diaphragm separation mechanisms start, and separate the diaphragms on the upper and lower surfaces of the positive electrode respectively; S800. After the diaphragm on the upper and lower surfaces of the positive electrode is separated by the diaphragm separation mechanism, the positive electrode receiving mechanism starts to operate to wind up the positive electrode. When the positive electrode receiving mechanism winds up the positive electrode, the film pulling mechanism is released.

[0016] The beneficial effects of this invention are: through the close cooperation between various mechanisms, the reverse precise separation and dismantling of waste laminated battery cell rolls is achieved, that is: the negative electrode, positive electrode and separator in the laminated battery cell roll are precisely separated and dismantled in a near-complete manner, thereby replacing manual dismantling, improving the efficiency and safety of waste battery recycling and reuse, realizing the automation of battery cell roll dismantling, and achieving time reduction and production increase. The entire equipment has a simple and compact structure, a high degree of automation in stripping the positive and negative electrodes and separators of the battery cell roll, and is applicable to the precise dismantling of battery cell rolls of different sizes.

Detailed Implementation

[0019] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0020] Example 1 like Figures 1 to 15 As shown, a reverse precision separation and dismantling device for battery cell rolls includes: a limiting and blocking mechanism 1, a diaphragm peeling mechanism 2, and a film pulling mechanism 3. The limiting and blocking mechanism 1, the diaphragm peeling mechanism 2, and the film pulling mechanism 3 are sequentially fixed on the frame 14 along the flow direction of the battery cell rolls. First, the battery cell roll to be separated and dismantled is placed on the limiting and blocking mechanism 1, and the limiting and blocking mechanism 1 limits the battery cell roll in the X and Y axis directions, that is, the battery cell roll is in the expected position in the X and Y axis directions and does not move, in preparation for the subsequent one-time cutting and clamping of the diaphragm. The frame 14 is provided with a diaphragm primary cutting mechanism 5. The diaphragm primary cutting mechanism 5 is used to cut the diaphragm on the surface of the battery cell roll that is limited by the limiting blocking mechanism 1. Since the outer end of the diaphragm on the surface of the battery cell roll is thermally sealed with other areas of itself after being wound together with the negative and positive electrodes, the battery cell roll can only be separated and disassembled in the form of unwinding after cutting the outer end. When the diaphragm primary cutting mechanism 5 cuts the diaphragm on the surface, it does not cut the negative electrode at the same time, but only cuts the diaphragm on the surface of the battery cell roll. The frame 14 is equipped with a lifting mechanism 4, which is used to lift the battery cell roll that is limited by the limiting and blocking mechanism 1 in the Z-axis direction. The lifting process is carried out only after the diaphragm cutting mechanism 5 has completed cutting the diaphragm on the surface of the battery cell roll that is limited by the limiting and blocking mechanism 1. The frame 14 is provided with a dewinding mechanism 6, which is used to clamp the battery coil on the lifting mechanism 4 and transfer it to the diaphragm peeling mechanism 2. The anti-winding mechanism 6 is equipped with an air brush connected to an air source via a pipeline. Gas from the air source can enter the air brush through the pipeline and then flow out through the air brush. The gas flowing out of the air brush flows towards the break point of the surface diaphragm in the battery cell roll held by the anti-winding mechanism 6. The airflow blows open the end of the surface diaphragm break point and allows it to be gripped by the diaphragm peeling mechanism 2. The diaphragm peeling mechanism 2 performs a first-grab-then-suck action. After the end of the surface diaphragm break point is blown open and gripped by the diaphragm peeling mechanism 2, the anti-winding mechanism 6 is used to unwind the gripped battery cell roll. A negative electrode receiving mechanism 7 is provided on the frame 14 between the limiting blocking mechanism 1 and the diaphragm peeling mechanism 2, and a diaphragm separation mechanism 8, a diaphragm secondary cutting mechanism 9 and a positive electrode receiving mechanism 10 are arranged sequentially between the diaphragm peeling mechanism 2 and the film pulling mechanism 3. The number of membrane separation mechanisms 8 is two, and they are arranged in a top-bottom configuration. The lower membrane separation mechanism 8 is fixed to the frame 14, and the upper membrane separation mechanism 8 is fixed to the frame 14 via the sixth lifting mechanism 11. There are two diaphragm secondary cutting mechanisms 9, which are distributed in a top-bottom configuration. The lower diaphragm secondary cutting mechanism 9 is fixed to the frame 14, while the upper diaphragm secondary cutting mechanism 9 is fixed to the frame 14 via the seventh lifting mechanism 12. Limiting and blocking mechanism 1, diaphragm peeling mechanism 2, film pulling mechanism 3, lifting mechanism 4, diaphragm primary cutting mechanism 5, anti-winding mechanism 6, negative electrode receiving mechanism 7, diaphragm separation mechanism 8, diaphragm secondary cutting mechanism 9, positive electrode receiving mechanism 10, sixth lifting mechanism 11, and seventh lifting mechanism 12 are electrically connected to the controller. That is, the controller can control the actions of limiting and blocking mechanism 1, diaphragm peeling mechanism 2, film pulling mechanism 3, lifting mechanism 4, diaphragm primary cutting mechanism 5, anti-winding mechanism 6, negative electrode receiving mechanism 7, diaphragm separation mechanism 8, diaphragm secondary cutting mechanism 9, positive electrode receiving mechanism 10, sixth lifting mechanism 11, and seventh lifting mechanism 12 respectively.

[0021] The method for reverse precision separation and dismantling of battery cell rolls based on this battery cell roll reverse precision separation and dismantling equipment includes the following steps: S100. Place the battery cell roll on the limiting and blocking mechanism 1, and limit the battery cell roll in the X and Y axis directions by the limiting and blocking mechanism 1. S200, the diaphragm primary cutting mechanism 5 cuts the diaphragm on the surface of the battery cell roll that is limited by the limiting and blocking mechanism 1; S300, after the diaphragm primary cutting mechanism 5 cuts the diaphragm on the surface of the battery cell roll, the lifting mechanism 4 lifts the battery cell roll in the Z-axis direction. S400, the anti-winding mechanism 6 clamps the battery cell roll on the lifting mechanism 4 and transfers it to the diaphragm peeling mechanism 2. Then, the gas in the air source enters the blowing brush through the pipeline and flows out through the blowing brush. The gas flowing out of the blowing brush flows to the break point of the surface diaphragm in the battery cell roll clamped by the anti-winding mechanism 6. The airflow causes the end of the surface diaphragm break point to be blown open. The anti-winding mechanism 6 then rotates the battery cell roll in the opposite direction (usually two or three rotations are enough) to unwind the battery cell roll, allowing the negative end to fall into the negative electrode receiving mechanism 7 in a natural hanging manner. The unwound diaphragm + positive electrode + diaphragm is gripped and sucked by the diaphragm peeling mechanism 2. S500, the membrane pulling mechanism 3 first clamps the membrane + positive electrode + membrane gripped by the membrane peeling mechanism 2 and resets it. During the reset process, the membrane + positive electrode + membrane passes through two membrane separation mechanisms 8 distributed above and below, two membrane secondary cutting mechanisms 9 distributed above and below, and the positive electrode receiving mechanism 10. S600, the seventh lifting mechanism 12 controls the upper diaphragm secondary cutting mechanism 9 to move downward, and cooperates with the lower diaphragm secondary cutting mechanism 9 to clamp the diaphragm + positive electrode + diaphragm, so as to cut the diaphragm on the upper and lower surfaces of the positive electrode respectively. The diaphragm secondary cutting mechanism 9 only cuts the diaphragm on the upper and lower surfaces of the positive electrode, and does not cut the positive electrode. S700, the sixth lifting mechanism 11 controls the upper diaphragm separation mechanism 8 of the two diaphragm separation mechanisms 8 to move downward, the two diaphragm separation mechanisms 8 are started, and the diaphragms on the upper and lower surfaces of the positive electrode are separated respectively. S800. After the diaphragm on the upper and lower surfaces of the positive electrode is separated by the diaphragm separation mechanism 8, the positive electrode receiving mechanism 10 starts to operate to wind up the positive electrode. When the positive electrode receiving mechanism 10 winds up the positive electrode, the film pulling mechanism 3 is released.

[0022] Example 2 like Figure 3 , Figure 4 As shown, this embodiment is a further improvement on embodiment 1, as detailed below: The limiting and blocking mechanism 1 includes: a material platform 110, a first Y-axis telescopic mechanism 120, a first X-axis telescopic mechanism 130, a Y-axis limiting plate 140, and an X-axis limiting plate 150. The first Y-axis telescopic mechanism 120, the first X-axis telescopic mechanism 130, the Y-axis limiting plate 140, and the X-axis limiting plate 150 are arranged in a rectangular shape on the material platform 110. The defined Y-axis direction is the flow direction of the battery cell rolls. The material platform 110 is equipped with an inductive switch for sensing whether there are battery cell rolls within the rectangular area enclosed by the first Y-axis telescopic mechanism 120, the first X-axis telescopic mechanism 130, the Y-axis limiting plate 140, and the X-axis limiting plate 150. When the inductive switch senses a battery cell roll... When the sensor switches send a sensor signal back to the controller, the controller then controls the first Y-axis telescopic mechanism 120 and the first X-axis telescopic mechanism 130 to move. The first Y-axis telescopic mechanism 120 works with the Y-axis limiting plate 140 to limit the battery roll in the Y-axis direction, and the first X-axis telescopic mechanism 130 works with the X-axis limiting plate 150 to limit the battery roll in the X-axis direction. A hole 111 is made in the rectangular area enclosed by the first Y-axis telescopic mechanism 120, the first X-axis telescopic mechanism 130, the Y-axis limiting plate 140, and the X-axis limiting plate 150 on the material table 110. The size of the hole 111 is smaller than the size of the battery roll, so that the battery roll will not fall through the hole 111. The lifting mechanism 4 includes a second lifting mechanism 410 and a top plate 420. The top plate 420 is located inside the hole 111, meaning that the cross-sectional dimension of the top plate 420 is smaller than the cross-sectional dimension of the hole 111. The second lifting mechanism 410 is located below the material platform 110 and is fixed to the material platform 110 and the top plate 420. In this embodiment, the first Y-axis telescopic mechanism 120, the first X-axis telescopic mechanism 130, and the second lifting mechanism 410 can all be cylinders commonly used in the prior art. Of course, this is just an exemplary description, and in actual applications, electric cylinders, hydraulic cylinders, etc. can also be used.

[0023] Example 3 like Figure 3 , Figure 4 As shown, this embodiment is a further improvement on embodiment 2, as detailed below: The diaphragm cutting mechanism 5 includes a second Y-axis telescopic mechanism 510 and a first hot knife assembly 520. The second Y-axis telescopic mechanism 510 is located below the material table 110 and is fixed to the frame 14. The material table 110 can be an n-shaped structure or an inverted L-shaped structure. Its shape is not explicitly limited here. The second Y-axis telescopic mechanism 510 is fixed to a third lifting mechanism 530 located between the material table 110 and the diaphragm peeling mechanism 2. The third lifting mechanism 530 is fixed to the first hot knife assembly 520. The first hot knife assembly 520 is located above the battery roll on the material table 110. The diaphragm is cut by hot knife. When the hot knife temperature is within the expected range, the diaphragm can usually be cut in about five seconds. Both the second Y-axis telescopic mechanism 510 and the third lifting mechanism 530 can be cylinders commonly used in the prior art. Of course, this is just an example. In actual applications, electric cylinders, hydraulic cylinders, etc. can also be used.

[0024] After the limiting and blocking mechanism 1 finishes limiting the battery cell roll in the X and Y axis directions... The second Y-axis telescopic mechanism 510 starts to operate, controlling the third lifting mechanism 530 and the first hot knife assembly 520 to approach the battery cell roll along the Y-axis direction and move to the expected position (the expected position can be determined by installing common photoelectric switches or induction plates within the stroke range, and this method is also used in many other descriptions later). After that, the second Y-axis telescopic mechanism 510 stops operating, and the third lifting mechanism 530 controls the first hot knife assembly 520 to descend, so as to perform a hot cut on the diaphragm on the surface of the battery cell roll, thereby breaking the outer end of the diaphragm on the surface of the battery cell roll. The working principle of the first hot knife assembly 520 is: the hot knife is heated by electricity so that the hot knife has sufficient temperature to cut the outer end of the diaphragm on the surface of the battery cell roll. After the first hot knife assembly 520 completes the diaphragm cutting process, it will reset under the control of the second Y-axis telescopic mechanism 510 and the third lifting mechanism 530. The diaphragm secondary cutting mechanism 9 is also preferably a hot knife assembly, and its working principle is the same as that of the first hot knife assembly 520. In this embodiment, the so-called first cutting and second cutting only refer to the number of times the diaphragm is cut.

[0025] Example 4 like Figure 8 , Figure 9 , Figure 10 As shown, this embodiment is a further improvement on any one of embodiments 1 to 3, as detailed below: The anti-winding mechanism 6 includes: a second Y-axis moving mechanism 610, which is fixed on the frame 14; a fourth lifting mechanism 620 is fixed on the moving plate 615 of the second Y-axis moving mechanism 610; a first X-axis moving mechanism 630 fixed to the fourth lifting mechanism 620 is arranged below the second Y-axis moving mechanism 610; and two opposing clamping mechanisms 640 are arranged below the first X-axis moving mechanism 630 along the X-axis direction. The two clamping mechanisms 640 have the same structure. Under the action of the first X-axis moving mechanism 630, the two clamping mechanisms 640 open and close in the X-axis direction, or they can be understood as moving closer to each other and moving further away from each other in the X-axis direction. The process of moving closer to each other is called closing, and the process of moving further away from each other is called opening. The clamping mechanism 640 includes a third servo motor 641 and a transmission mechanism 642 fixed to the first X-axis moving mechanism 630. The third servo motor 641 is fixed to the transmission mechanism 642. The main shaft of the third servo motor 641 is fixed to the input shaft of the transmission mechanism 642. The output shaft of the transmission mechanism 642 is fixed to the clamping block 643. When the third servo motor 641 is started, it controls the clamping block 643 to rotate through the transmission mechanism 642. The rotation axis of the clamping block 643 is distributed along the X-axis direction. The transmission mechanism 642 includes a housing and a transmission chain inside the housing. The transmission chain can be a sprocket drive, gear drive, belt drive, etc.

[0026] The working principle of the anti-winding mechanism 6 is as follows: After the surface separator in the battery cell coil is cut, the second Y-axis moving mechanism 610 starts to operate. The second Y-axis moving mechanism 610 controls the fourth lifting mechanism 620, the first X-axis moving mechanism 630, and the two clamping mechanisms 640 to move in the Y-axis direction to approach the limiting blocking mechanism 1. After moving to the expected position, the second Y-axis moving mechanism 610 stops operating. Then, the fourth lifting mechanism 620 starts to operate, controlling the first X-axis moving mechanism 630 and the two clamping mechanisms 640 to descend in the Z-axis direction. After descending to the expected position, the fourth lifting mechanism 620 stops operating, and the first X-axis moving mechanism 630 starts to operate, controlling the two clamping mechanisms 640 to move closer to each other in the X-axis direction, thereby clamping the lifting mechanism 4. After the battery cell roll is clamped, the fourth lifting mechanism 620 controls the first X-axis moving mechanism 630, the two clamping mechanisms 640 and the battery cell roll to rise, and cooperates with the second Y-axis moving mechanism 610 to move the battery cell roll to the expected position. Then, the gas in the air source enters the blowing brush through the pipeline and flows out through the blowing brush. The gas flowing out of the blowing brush flows to the break point of the surface diaphragm in the battery cell roll clamped by the anti-winding mechanism 6. The airflow blows open the end of the surface diaphragm break point. Then the battery cell roll is rotated in the opposite direction (usually two or three rotations are enough) to unwind the battery cell roll, so that the negative end falls into the negative electrode receiving mechanism 7 in a natural hanging manner. The unwound diaphragm + positive electrode + diaphragm is grabbed and sucked by the diaphragm peeling mechanism 2.

[0027] The second Y-axis moving mechanism 610 can be a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder, or it can adopt the following structure: The system comprises a second driving wheel 611, a second driven wheel 612, a second servo motor 613, a second synchronous belt 614, a moving plate 615, and two second slide rails 616. The second driving wheel 611 and the second driven wheel 612 are rotatably fixed to the frame 14. The second synchronous belt 614 is wound between the second driving wheel 611 and the second driven wheel 612. The second servo motor 613 is fixed to the frame 14, and its spindle is fixedly connected to the second driving wheel 611. The two second synchronous belts 616... The slide rails 616 are distributed on both sides of the second synchronous belt 614 and are fixed to the frame 14 respectively. The two ends of the moving plate 615 are fixed to the sliders in the two second slide rails 616 respectively. The moving plate 615 is connected to a section of the synchronous belt 614. When the second servo motor 613 starts to operate, it can control the second driving wheel 611 to rotate, so that the second driving wheel 611 drives the second driven wheel 612 to rotate via the second synchronous belt 614, so that the moving plate 615 moves with the second synchronous belt 614 in the Y-axis direction.

[0028] The first X-axis moving mechanism 630 can adopt a common double slider lead screw module, or it can adopt the following structure: The system comprises a drive sprocket 631, a driven sprocket 632, a chain 633, a first base plate 634, a fifth servo motor 635, two assembly blocks 636, and two third slide rails 637. The first base plate 634 is fixed to the fourth lifting mechanism 620. The drive sprocket 631 and the driven sprocket 632 are rotatably mounted below the first base plate 634, with their rotation axes distributed along the Z-axis. The chain 633 winds between the drive sprocket 631 and the driven sprocket 632. A third slide rail 637, fixed to the first base plate 634, is located on each side of the chain 633 along the X-axis. Each assembly block 636 has its two ends fixedly connected to the sliders in the two third slide rails 637. A clamping mechanism 640 is fixed below 36. One of the two assembly blocks 636 is connected to one side of the chain 633, and the other block is connected to the other side of the chain 633. The fifth servo motor 635 is fixed on the first base plate 634. The main shaft of the fifth servo motor 635 is fixedly connected to the drive sprocket 631. When the fifth servo motor 635 is started, it controls the drive sprocket 631 to rotate. The drive sprocket 631 drives the driven sprocket 632 to rotate via the chain 633. Since the two assembly blocks 636 are respectively connected to the chain 633, the two assembly blocks 636 will move closer and further away from each other under the action of the chain 633, thereby controlling the two clamping mechanisms 640 to move closer and further away from each other.

[0029] Example 5 like Figure 11 As shown, this embodiment is a further improvement on any one of embodiments 1 to 4, as detailed below: The negative electrode receiving mechanism 7 includes: a first electric roller 710 and a third Y-axis moving mechanism 720. The first electric roller 710 and the third Y-axis moving mechanism 720 are fixedly connected to the frame 14. The rotation axis of the first electric roller 710 is distributed along the X-axis. A first passive roller 730 parallel to the first electric roller 710 is rotatably connected to the third Y-axis moving mechanism 720. Under the action of the third Y-axis moving mechanism 720, the first passive roller 730 moves closer to and further away from the first electric roller 710 in the Y-axis direction. The working principle of the negative electrode receiving mechanism 7 is as follows: When the negative electrode unwinding from the battery cell coil by the anti-winding mechanism 6 falls naturally between the first electric roller 710 and the first passive roller 730, the third Y-axis moving mechanism 720 starts to operate and controls the first passive roller 730 to move closer to the first electric roller 710 in the Y-axis direction. The first passive roller 730 cooperates with the first electric roller 710 to clamp the negative electrode. At the same time, the first electric roller 710 starts to operate, thereby pulling the negative electrode.

[0030] In this embodiment, the third Y-axis moving mechanism 720 can be at least one pneumatic cylinder, electric cylinder, or hydraulic cylinder, or it can adopt the following structure: The system includes two fourth slide rails 721, a second movable support 722, and a first Y-axis cylinder 723. The two fourth slide rails 721 are fixed on the frame 14 and distributed along the Y-axis. The two ends of the second movable support 722 are fixed to the sliders of the two fourth slide rails 721. The two ends of the first passive roller 730 are rotatably connected to the second movable support 722. The first Y-axis cylinder 723 is fixed on the frame 14, and the piston rod of the first Y-axis cylinder 723 is fixed to the second movable support 722. When the first Y-axis cylinder 723 starts to move, it can control the second movable support 722 to reciprocate on the slide rail, thereby enabling the first passive roller 730 to move closer to and further away from the first electric roller 710 in the Y-axis direction.

[0031] Example 6 like Figure 7 As shown, this embodiment is a further improvement on any one of embodiments 1 to 5, as detailed below: The film stretching mechanism 3 includes: a first Y-axis moving mechanism 310, which is fixed on the frame 14. At least one second pneumatic gripper 320 is fixed side by side on the first Y-axis moving mechanism 310. As shown in the figure, there are two second pneumatic grippers 320. In the figure, one of the two second pneumatic grippers 320 is in an open state and the other is in a closed state. Both second pneumatic grippers 320 have the function of opening and closing at the same time. The first Y-axis moving mechanism 310 can be a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder, or it can adopt the following structure: The system comprises a base frame 311, a first driving wheel 312, a first driven wheel 313, a first servo motor 314, a first synchronous belt 315, a first moving bracket 316, and two first slide rails 317. The base frame 311 is fixed to the frame 14 along the Y-axis. The first driving wheel 312 is rotatably mounted on the base frame 311, with its rotation axis distributed along the X-axis. The first driven wheel 313 is rotatably mounted on the base frame 311, with its rotation axis distributed along the X-axis. The first servo motor 314 is fixed to the base frame 311. The main shaft of the first servo motor 314 is fixed to the first drive wheel 312. The first synchronous belt 315 is wrapped between the first drive wheel 312 and the first driven wheel 313. The first synchronous belt 315 extends from the adjacent diaphragm peeling mechanism 2 to beyond the positive electrode receiving mechanism 10. One end of the first moving bracket 316 is connected to the first synchronous belt 315, and at least one second pneumatic gripper 320 is fixed side by side at the other end. Two first slide rails 317 are fixed side by side on the base frame 311 along the Y-axis direction. The first moving bracket 316 is fixed to the slider on each first slide rail 317. The second pneumatic gripper 320 can be a finger cylinder + two film-pulling grippers, that is, the two film-pulling grippers are respectively fixed on the two fingers of the finger cylinder. The first servo motor 314 starts to operate, driving the first drive wheel 312 to rotate. The first drive wheel 312 then controls the first driven wheel 313 to rotate via the first synchronous belt 315, thereby causing the first moving bracket 316, which is fixed to the first synchronous belt 315, to move in the Y-axis direction. The second pneumatic gripper 320 moves synchronously with the first moving bracket 316. When the second pneumatic gripper 320 moves to the expected position, the first servo motor 314 stops operating, and the second pneumatic gripper 320 starts operating to grip the diaphragm + positive electrode + diaphragm held by the diaphragm peeling mechanism 2. The first servo motor 314 starts to rotate in the opposite direction, thereby controlling the second pneumatic gripper 320 to reset the diaphragm + positive electrode + diaphragm.

[0032] Example 7 like Figure 5 , Figure 6 As shown, this embodiment is a further improvement on embodiment 6, as detailed below: The diaphragm peeling mechanism 2 includes: a base 210, which is fixed on the frame 14. A first lifting mechanism 220 is fixed below the base 210. A mounting plate 230 fixed to the first lifting mechanism 220 is arranged above the base 210. The first lifting mechanism 220 can control the mounting plate 230 to lift in the Z-axis direction. A buffer plate 240 and an air nozzle assembly 250 are provided on the side of the mounting plate 230 near the limiting and blocking mechanism 1. At least one first pneumatic gripper 260 is provided below the mounting plate 230. The first pneumatic gripper 260 may include: a first cylinder 261 and a diaphragm gripper 262. The cylinder body of the first cylinder 261 is rotatably connected to the mounting plate 230. The first cylinder 261 is distributed along the X-axis direction around the rotation axis of the mounting plate 230. The middle of the diaphragm gripper 262 is rotatably connected to the mounting plate 230. The diaphragm gripper 262 is distributed along the X-axis direction around the rotation axis of the mounting plate 230. The lower end of the diaphragm gripper 262 is rotatably connected to the piston rod of the first cylinder 261. The diaphragm gripper 262 is distributed along the X-axis direction around the rotation axis of the first cylinder 261. The first cylinder 261 can control the upper end of the diaphragm gripper 262 to move closer to and further away from the buffer plate 240 through extension and retraction. When it is close, the upper end of the diaphragm gripper 262 can cooperate with the buffer plate 240 to clamp the diaphragm + positive electrode + diaphragm. The buffer plate 240 can also be used to prevent impact. A ninth lifting mechanism 270 is fixed on the base 210 between the mounting plate 230 and the limiting blocking mechanism 1. A diaphragm release plate 280 is fixed on the ninth lifting mechanism 270. A transition roller 290 is rotatably provided on the side of the diaphragm release plate 280 near the limiting blocking mechanism 1. The rotation axis of the transition roller 290 is distributed along the X-axis. The ninth lifting mechanism 270 can control the diaphragm release plate 280 and the transition roller 290 to lift in the Z-axis direction. A clearance notch 281 is provided on the diaphragm release plate 280 at each corresponding second pneumatic gripper 320. The clearance notch 281 is used to avoid the membrane pulling gripper in the second pneumatic gripper 320. The working principle of the diaphragm peeling mechanism 2 is as follows: The first lifting mechanism 220 starts to operate and controls the mounting plate 230, the air nozzle assembly 250 and the first pneumatic gripper 260 to rise in the Z-axis direction. Then the air nozzle assembly 250 starts to suck air to attract the diaphragm + positive electrode + diaphragm to move towards it and suck the diaphragm + positive electrode + diaphragm. The first pneumatic gripper 260 operates to cooperate with the buffer plate 240 to clamp the diaphragm + positive electrode + diaphragm. The ninth lifting mechanism 270 starts to operate and controls the diaphragm release plate 280 and the transition roller 290 to rise in the Z-axis direction. When it rises to the expected position, the ninth lifting mechanism 270 stops operating. Then, the first Y-axis moving mechanism 310 in the membrane pulling mechanism 3 starts to operate and controls the second pneumatic gripper 320 to approach the diaphragm peeling mechanism 2 in the Y-axis direction. When it moves to the expected position, the first Y-axis moving mechanism 310 stops operating, and the second pneumatic gripper 320 starts to operate to clamp the diaphragm + positive electrode + diaphragm. Then, the first Y-axis moving mechanism 310 controls the second pneumatic gripper 320 to reset the diaphragm + positive electrode + diaphragm.

[0033] Example 8 like Figure 12 , Figure 13 , Figure 14As shown, this embodiment is a further improvement on any one of embodiments 1 to 7, as detailed below: The diaphragm separation mechanism 8 includes: a base 810. For the lower diaphragm separation mechanism 8, the base 810 is fixed to the frame 14. For the upper diaphragm separation mechanism 8, the base 810 is fixed to the sixth lifting mechanism 11. A fifth lifting mechanism 860 is fixed on the side of the base 810 away from the transmission surface (away from the surface of the diaphragm + positive electrode + diaphragm held by the film pulling mechanism 3). A film suction assembly 820, fixed to the fifth lifting mechanism 860 and distributed along the X-axis, is arranged on the side of the base 810 near the transmission surface. A fourth Y-axis moving mechanism 850 is fixed. A second passive roller 830 and a second electric roller 840 are respectively arranged on both sides of the film suction assembly 820. The second passive roller 830 is rotatably connected to the fourth Y-axis moving mechanism 850. The fourth Y-axis moving mechanism 850 is used to control the second passive roller 830 to move closer to and away from the second electric roller 840. The second electric roller 840 is fixed to the base 810. The fifth lifting mechanism 860 can be a cylinder commonly used in the prior art. Of course, this is only an exemplary description. In actual applications, electric cylinders, hydraulic cylinders, etc. can also be used.

[0034] The fourth Y-axis moving mechanism 850 can be a cylinder commonly used in the prior art. Of course, this is just an example. In actual applications, electric cylinders, hydraulic cylinders, etc. can also be used, or the following structure can be adopted: The second Y-axis cylinder 851, the fifth slide rail 852, and the third moving bracket 853 are fixed on the base 810. One end of the third moving bracket 853 is fixedly connected to the piston rod of the second Y-axis cylinder 851, and the other end of the third moving bracket 853 is fixedly connected to the slider in the fifth slide rail 852. The second Y-axis cylinder 851 can control the third moving bracket 853 to move along the Y-axis on the fifth slide rail 852 through its extension and retraction action, thereby allowing the second passive roller 830 to move along with it, so as to move closer to and further away from the second electric roller 840.

[0035] The working principle of the diaphragm separation mechanism 8 is as follows: After the second pneumatic gripper 320 in the membrane pulling mechanism 3 clamps the diaphragm + positive electrode + diaphragm and resets, the two secondary diaphragm cutting mechanisms 9 are located above and below the diaphragm + positive electrode + diaphragm, respectively. Similarly, the two diaphragm separation mechanisms 8 are also located above and below the diaphragm + positive electrode + diaphragm, respectively. The seventh lifting mechanism 12 operates to control the upper secondary diaphragm cutting mechanism 9 to move downward, thereby cooperating with the lower secondary diaphragm cutting mechanism 9 to clamp the diaphragm + positive electrode + diaphragm, so as to cut the diaphragm on the upper and lower surfaces of the positive electrode, respectively. Then the sixth lifting mechanism 11 starts to operate to control the upper diaphragm separation mechanism 8 of the two diaphragm separation mechanisms 8 to move downward. After moving downward to the expected position, the sixth lifting mechanism 11 stops operating. The two second passive rollers 830 in the two diaphragm separation mechanisms 8 cooperate to clamp the positive electrode, and the two second electric rollers 840 cooperate to clamp the positive electrode, which can prevent the positive electrode from breaking during the separation and disassembly process. The fifth lifting mechanism 860 in the upper diaphragm separation mechanism 8 starts to operate, controlling the upper membrane suction assembly 820 to move downward. The fifth lifting mechanism 860 in the lower diaphragm separation mechanism 8 starts to operate, controlling the lower membrane suction assembly 820 to move upward. The two membrane suction assemblies 820 are activated respectively, thereby suctioning the membranes on the upper and lower surfaces of the positive electrode. After the two membrane suction assemblies 820 suction the membranes on the upper and lower surfaces of the positive electrode respectively, the two fifth lifting mechanisms 860 control the two membrane suction assemblies 820 to return to their original position while suctioning the membranes. The fourth Y-axis moving mechanism 850 in the diaphragm separation mechanism 8 starts to operate, so as to control the second passive roller 830 to approach the second electric roller 840, so that the second passive roller 830 cooperates with the second electric roller 840 to clamp the diaphragm sucked by the film suction assembly 820. The second electric roller 840 starts to start, so as to wind the diaphragm on it.

[0036] Example 9 like Figure 15 As shown, this embodiment is a further improvement on any one of embodiments 1 to 8, as detailed below: The positive electrode receiving mechanism 10 includes: a second base plate 1010, which is fixed on the frame 14. A second X-axis moving mechanism 1020 is provided on the second base plate 1010. The second X-axis moving mechanism 1020 is fixed to a fourth servo motor 1030. The main shaft of the fourth servo motor 1030 is fixed to a winding needle 1050 via a damper 1040. The second X-axis moving mechanism 1020 is used to control the fourth servo motor 1030, the damper 1040, and the winding needle 1050 to move along the X-axis. When the diaphragm on the upper and lower surfaces of the positive electrode is separated by the diaphragm separation mechanism 8, the second X-axis moving mechanism 1020 starts to operate to control the winding needle 1050 to move along the X-axis, allowing the positive electrode to enter the winding needle 1050. Then, the fourth servo motor 1030 starts and controls the winding needle 1050 to rotate via the damper 1040, thereby winding the positive electrode onto the winding needle 1050.

[0037] The second X-axis moving mechanism 1020 can be a cylinder commonly used in the prior art. Of course, this is just an example. In actual applications, electric cylinders, hydraulic cylinders, etc., can also be used, or the following structure can be adopted: The third base plate 1021, the first X-axis cylinder 1022, and the sixth slide rail 1023 are respectively fixed to the second base plate 1010. The third base plate 1021 is fixed to the slider of the sixth slide rail 1023. The piston rod of the first X-axis cylinder 1022 is fixedly connected to the third base plate 1021. The fourth servo motor 1030 is fixed to the third base plate 1021. When the first X-axis cylinder 1022 starts, it can control the third base plate 1021 to move along the X-axis direction on the sixth slide rail 1023. Finally, it can control the fourth servo motor 1030, the damper 1040, and the winding needle 1050 to move along the X-axis direction.

[0038] Example 10 like Figure 12 , Figure 13 As shown, this embodiment is a further improvement on any one of embodiments 1 to 9, as detailed below: A belt-pulling mechanism 13 is provided between the diaphragm peeling mechanism 2 and the diaphragm separation mechanism 8, and between the positive electrode receiving mechanism 10 and the film pulling mechanism 3. The belt-pulling mechanism 13 includes a third passive roller 1310 and a third electric roller 1320 distributed vertically. The third passive roller 1310 is fixed to the frame 14 via an eighth lifting mechanism 1330, and the third electric roller 1320 is also fixed to the frame 14. The rotation axes of the third passive roller 1310 and the third electric roller 1320 are distributed along the X-axis. In the second... After the pneumatic gripper 320 clamps the diaphragm + positive electrode + diaphragm and resets, the eighth lifting mechanism 1330 starts to operate to control the third passive roller 1310 to move downward, thereby cooperating with the third electric roller 1320 to clamp the diaphragm + positive electrode + diaphragm. The belt pulling mechanism 13 can not only transport the diaphragm + positive electrode + diaphragm, but also prevent the positive electrode from breaking during the separation and disassembly process. The eighth lifting mechanism 1330 can be a cylinder commonly used in the prior art. Of course, this is just an example. In actual applications, electric cylinders, hydraulic cylinders, etc. can also be used.

10. A method for precise reverse separation and disassembly of battery cell rolls, characterized in that, The reverse precision separation and dismantling equipment for battery cell rolls as described in any one of claims 1 to 9 includes the following steps: S100. Place the battery cell roll on the limiting and blocking mechanism (1), and limit the battery cell roll in the X and Y axis directions by the limiting and blocking mechanism (1); S200, the diaphragm primary cutting mechanism (5) cuts the diaphragm on the surface of the battery cell roll that is limited by the limiting blocking mechanism (1); S300, Lifting mechanism (4) lifts the battery roll in the Z-axis direction after the diaphragm cutting mechanism (5) cuts the diaphragm on the surface of the battery roll; S400, the anti-winding mechanism (6) clamps the battery cell roll on the lifting mechanism (4) and transfers it to the diaphragm peeling mechanism (2). Then, the gas in the gas source enters the blowing brush through the pipeline and flows out through the blowing brush. The gas flowing out of the blowing brush flows to the break point of the surface diaphragm in the battery cell roll clamped by the anti-winding mechanism (6). The airflow causes the end of the break point of the surface diaphragm to be blown open. The anti-winding mechanism (6) then rotates the battery cell roll in the opposite direction to unwind the battery cell roll, allowing the negative end to fall into the negative electrode receiving mechanism (7) in a natural hanging manner. The unwound diaphragm + positive electrode + diaphragm is gripped and sucked by the diaphragm peeling mechanism (2). S500, the membrane pulling mechanism (3) first clamps the membrane + positive electrode + membrane that the membrane peeling mechanism (2) has grabbed and sucked, and resets it. During the reset process, the membrane + positive electrode + membrane passes through two membrane separation mechanisms (8) distributed above and below, two membrane secondary cutting mechanisms (9) distributed above and below, and the positive electrode receiving mechanism (10). S600, the seventh lifting mechanism (12) controls the upper diaphragm secondary cutting mechanism (9) to move downward, and cooperates with the lower diaphragm secondary cutting mechanism (9) to clamp the diaphragm + positive electrode + diaphragm, so as to cut the diaphragm on the upper and lower surfaces of the positive electrode respectively. S700, the sixth lifting mechanism (11) controls the upper diaphragm separation mechanism (8) of the two diaphragm separation mechanisms (8) to move downward, the two diaphragm separation mechanisms (8) start, and separate the diaphragms on the upper and lower surfaces of the positive electrode respectively; S800. After the diaphragm on the upper and lower surfaces of the positive electrode is separated by the diaphragm separation mechanism (8), the positive electrode receiving mechanism (10) starts to operate to wind up the positive electrode. When the positive electrode receiving mechanism (10) winds up the positive electrode, the film pulling mechanism (3) is released.
