[0033] In the embodiment of the present application, the battery cell may be a secondary battery. A secondary battery refers to a battery cell that can be continuously used by activating active materials by charging after the battery cell is discharged.

[0034] The battery cell can be a lithium ion battery, a sodium ion battery, a sodium lithium ion battery, a lithium metal battery, a sodium metal battery, a lithium sulfur battery, a magnesium ion battery, a nickel hydrogen battery, a nickel cadmium battery, a lead storage battery, etc., which is not limited in the embodiments of the present application.

[0035] The battery cell can be cylindrical, flat, rectangular or other shapes, and the present application embodiment does not limit this. Battery cells are generally divided into three types according to the packaging method: cylindrical battery cells, square battery cells and soft-pack battery cells, and the present application embodiment does not limit this.

[0036] The battery cell includes a shell, an electrode assembly and an electrolyte, and the shell is used to contain the electrode assembly and the electrolyte. The electrode assembly is composed of a positive electrode sheet, a negative electrode sheet and a separator. The battery cell mainly relies on the movement of metal ions between the positive electrode sheet and the negative electrode sheet to work. The positive electrode sheet includes a positive electrode collector and a positive electrode active material layer. The positive electrode collector includes a positive electrode collector body and a positive electrode ear. The positive electrode active material layer is coated on the surface of the positive electrode collector body.

[0039] The inventors found that in the field of battery recycling, there are waste battery products in single rolls. After the capacity of these waste batteries is reduced to a certain level, they can no longer be used in the original equipment, but they still have residual value, so they can be recycled and reused or recycled. At the same time, in the production process of the battery, the first and last pole pieces of each roll are single roll bad products. For example, for single roll bad products, in the production process of the wound electrode assembly, the diaphragm, the positive pole piece and the negative pole piece are formed into a single roll core by a winding machine, wherein the diaphragm plays the role of isolating the positive and negative pole pieces to prevent internal short circuits in the battery. In the winding process, due to the limitations of the process and equipment, the first and last parts of each roll are often unable to form complete pole pieces, so they are regarded as single roll bad products. Although these first and last pole pieces are cut off, they are not actually contaminated by the electrolyte, so they have a higher recycling value.

[0040] In the related art, these single roll cores are usually recycled, and the recycling process usually includes steps such as collection, classification, cleaning, inspection and repair. The collection process needs to ensure that the pole pieces are not contaminated or damaged. The classification process distinguishes according to the type and state of the pole pieces. The cleaning process is used to remove impurities and dirt on the surface of the pole pieces. The inspection process is used to evaluate the performance and reusability of the pole pieces. The repair process is used to repair damaged pole pieces or restore their performance. The first and last pole pieces after recycling and repair can be reused in the battery production process as a component of a new battery, and can also be used to repair or replace damaged battery pole pieces, thereby reducing production costs and reducing resource waste. However, the existing single roll pole piece disassembly equipment has a low degree of automation, and the efficiency of pole piece disassembly and recycling is not high, which is not conducive to promotion and use.

[0041] Based on the above considerations, in order to solve the problem of low efficiency in disassembly and recycling of single-roll pole pieces, the inventors have designed a disassembly device after in-depth research, which is applied to the disassembly of single-roll cores, including: a logistics line, a diaphragm cutting module, a diaphragm unfolding module, a lifting module and a diaphragm winding module. The logistics line is used to transport the core to be disassembled, the diaphragm cutting module is used to cut off the diaphragm on the outer layer of the core to be disassembled, the diaphragm unfolding module is used to unfold the cut diaphragm from the core to be disassembled, the lifting module is used to grab the core to be disassembled with the unfolded diaphragm and lift it, and the diaphragm winding module is used to wind up the diaphragm.

[0042] In the disassembly equipment of this structure, by setting up multiple processing modules along the logistics line and cooperating with each other, the pole pieces of a single roll core can be automatically disassembled and recovered, thereby effectively improving the efficiency of disassembly and recovery of single roll pole pieces, which is conducive to reducing the production cost of batteries and reducing waste of resources.

[0043] According to some embodiments of the present application, referring to Figure 1 , Figure 1 The present application provides a disassembly device 1 for disassembling a single roll core 170 , including a logistics line 110 , a membrane cutting module 120 , a membrane unfolding module 130 , a lifting module 140 and a membrane winding module 160 .

[0044] During the disassembly of a single roll core 170, the logistics line 110 is responsible for transporting the core 170 to be disassembled from the loading station to the disassembly equipment 1 to prepare for the subsequent disassembly steps. The logistics line 110 is usually a highly automated and intelligent system with a speed regulation function so that the core 170 can move smoothly and continuously, and is convenient for docking with other modules.

[0045] Exemplarily, the logistics line 110 can be a conveyor belt to improve production efficiency, and the logistics line 110 can be equipped with a dust cover or dust curtain to reduce dust and impurities from entering the production line and affecting the quality of the core 170 and the performance of the disassembly equipment 1. The logistics line 110 can also be equipped with anti-static equipment to facilitate the safe transportation of the core 170.

[0046] The diaphragm cutting module 120 is arranged along the logistics line 110, located downstream of the loading station, and is used to cut off the outermost diaphragm 173 of the core 170 to be disassembled. The diaphragm cutting module 120 has precise cutting ability and stable cutting performance, and can cut the diaphragm 173 by hot cutting, cold cutting or laser cutting.

[0047] The membrane unfolding module 130 is responsible for unfolding the cut membrane 173 from the winding core 170 to be disassembled, in preparation for the subsequent lifting and winding steps. The membrane unfolding module 130 can unfold the membrane 173 smoothly and evenly to reduce tearing or wrinkling during the unfolding process.

[0048] The lifting module 140 is used to grab the unfolded core 170 to be disassembled of the diaphragm 173 and lift it to a certain height for the subsequent step of winding up the diaphragm 173. The lifting module 140 has precise grabbing ability and stable lifting performance. In addition, the lifting module 140 can also loosen the core 170 when the diaphragm 173 is wound up, so that the core 170 can separate the diaphragm 173 and the pole piece when it falls.

[0049] The diaphragm winding module 160 is responsible for winding the diaphragm 173 unrolled from the winding core 170 and arranging it into a roll for subsequent storage and processing. The diaphragm winding module 160 has an efficient winding capacity and a stable winding performance to roll up the diaphragm 173 neatly and tightly.

[0050] In the actual working process, the core 170 to be disassembled is transported to the diaphragm 173 cutting station through the logistics line 110, the diaphragm cutting module 120 cuts off the diaphragm 173 on the outer layer of the core 170, and then the cut core 170 is transported to the diaphragm 173 unfolding station through the logistics line 110, the diaphragm unfolding module 130 unfolds the cut diaphragm 173 from the core 170, the lifting module 140 grabs the unfolded core 170 of the diaphragm 173 and lifts it to a certain height, the diaphragm winding module 160 starts to wind up the unfolded diaphragm 173, and during the diaphragm winding process, the lifting module 140 releases the core 170 to separate the diaphragm 173 and the pole piece when the core 170 falls.

[0051] The disassembly equipment 1 provided in the present application integrates multiple functional modules, and the modules cooperate with each other to achieve efficient and automated disassembly of a single roll core 170, thereby effectively improving the disassembly efficiency, reducing the production cost of the battery, and reducing resource waste.

[0052] According to some embodiments of the present application, referring to Figure 4 and Figure 5 , Figure 4 A schematic diagram of the structure of the lifting module 140 provided in some embodiments of the present application. Figure 5 A schematic diagram of the structure of the identification module 150 provided in some embodiments of the present application. The disassembling device 1 further includes: an identification module 150, which is arranged along the logistics line 110, and is used to identify the unfolding direction of the core 170 to be disassembled when the lifting module 140 lifts the core 170 to be disassembled, and send the identification result to the lifting module 140.

[0053] During the actual working process, the core 170 to be disassembled is transported to the diaphragm 173 cutting station through the logistics line 110, the diaphragm cutting module 120 cuts off the diaphragm 173 on the outer layer of the core 170, and then the cut core 170 is transported to the diaphragm 173 unfolding station through the logistics line 110, the diaphragm unfolding module 130 unfolds the cut diaphragm 173 from the core 170, the lifting module 140 grabs the core 170 with the unfolded diaphragm 173 and lifts it to a certain height. When the lifting module 140 lifts the core 170 to be disassembled, the recognition module 150 is responsible for determining the unfolding direction of the diaphragm 173 and sending the recognition result to the lifting module 140.

[0054] The recognition module 150 can use advanced image recognition or sensor technology to complete the recognition task with high accuracy and speed. The recognition result will be sent to the lifting module 140 to guide the rotating mechanism 142 to make necessary adjustments so that the deployment direction of the diaphragm 173 is consistent with the target direction.

[0055] The lifting module 140 includes a lifting mechanism 141, a rotating mechanism 142 and a clamping mechanism 143. The lifting mechanism 141 is responsible for grabbing and lifting the core 170 to be disassembled whose diaphragm 173 has been unfolded. The rotating mechanism 142 is installed on the lifting mechanism 141 and is used to adjust the direction of the clamping mechanism 143 according to the result of the identification module 150. The clamping mechanism 143 is installed on the rotating mechanism 142 and is used to clamp the core 170 to be disassembled.

[0056] The diaphragm winding module 160 is responsible for winding the diaphragm 173 unfolded from the winding core 170, and the diaphragm winding module 160 can only process the diaphragm 173 whose unfolding direction is consistent with the target direction. When the identification module 150 finds that the unfolding direction of the diaphragm 173 is opposite to the target direction, the rotating mechanism 142 will start and rotate the clamping mechanism 143 until the unfolding direction of the diaphragm 173 is consistent with the target direction.

[0057] like Figure 7-Figure 16As shown, the membrane 173 can be wound in a variety of structural forms, but the membrane 173 can be unfolded in only two directions: clockwise single-roll unfolding and counterclockwise single-roll unfolding.

[0058] The single roll core 170 can be divided into a double-layer diaphragm 173 sandwiching a cathode electrode piece 171 and a double-layer diaphragm 173 sandwiching an anode electrode piece 172 according to the winding form. The winding direction of the diaphragm 173 is divided into clockwise winding and counterclockwise winding. The single roll form includes: like Figure 7 As shown, Figure 7 This is one of the structural schematic diagrams of the winding core 170 provided in some embodiments of the present application, where A1 upper layer diaphragm 173 + cathode electrode 171 + lower layer diaphragm 173 are wound clockwise.

[0059] like Figure 8 As shown, Figure 8 The second structural schematic diagram of the winding core 170 provided in some embodiments of the present application, A2 upper diaphragm 173 + lower diaphragm 173 + cathode electrode 171 are wound clockwise.

[0060] like Fig. 9 As shown, Fig. 9 The third structural schematic diagram of the winding core 170 provided in some embodiments of the present application, A3 upper diaphragm 173 + cathode electrode 171 + lower diaphragm 173 are wound counterclockwise.

[0061] like Fig.10 As shown, Fig.10 The fourth structural schematic diagram of the winding core 170 provided in some embodiments of the present application, A4 upper diaphragm 173 + lower diaphragm 173 + cathode electrode 171 are wound counterclockwise.

[0062] like Fig.11 As shown, Fig.11 The fifth structural schematic diagram of the winding core 170 provided in some embodiments of the present application, A5 upper diaphragm 173 + anode electrode 172 + lower diaphragm 173 are wound clockwise.

[0063] like Fig.12 As shown, Fig.12 The sixth structural schematic diagram of the winding core 170 provided in some embodiments of the present application, A6 upper diaphragm 173 + lower diaphragm 173 + anode electrode 172 are wound clockwise.

[0064] like Fig.13 As shown, Fig.13 The seventh structural schematic diagram of the winding core 170 provided in some embodiments of the present application, A7 upper diaphragm 173 + anode electrode 172 + lower diaphragm 173 are wound counterclockwise.

[0065] like Fig.14 As shown, Fig.14The eighth structural schematic diagram of the winding core 170 provided in some embodiments of the present application, A8 upper diaphragm 173 + lower diaphragm 173 + anode electrode 172 are wound counterclockwise.

[0066] like Fig.15 and Fig.16 As shown, Fig.15 The ninth structural diagram of the winding core 170 provided in some embodiments of the present application is as follows: Fig.16 This is a tenth structural schematic diagram of the winding core 170 provided in some embodiments of the present application. Fig.15 To unfold the single roll counterclockwise, Fig.16 For clockwise single roll unfolding, after pre-processing, the above-mentioned different forms of single roll cores 170 have only clockwise single roll unfolding and counterclockwise single roll unfolding directions, and their outer layer structures are all single roll pole pieces, and the inner layer is a two-layer diaphragm 173.

[0067] After the diaphragm 173 of the single roll core 170 is cut and unfolded, the single roll cores A3, A4, A7 and A8 are processed into a counterclockwise single roll unfolding form, and the single roll cores A1, A2, A5 and A6 are processed into a clockwise single roll unfolding form. The clockwise wound single roll core 170 is unfolded by rotating counterclockwise, and the counterclockwise wound single roll core 170 is unfolded by rotating clockwise. After unfolding, the outer electrode sheet naturally droops to the waste electrode sheet box under the action of gravity, and the single roll is disassembled after the diaphragm 173 is rolled up.

[0068] It is understandable that, by adding the identification module 150 and refining the design of the lifting module 140, the disassembly device 1 can accurately identify and adjust the unfolding direction of the diaphragm 173 of the core 170 to be disassembled, thereby further improving the disassembly efficiency and accuracy.

[0069] According to some embodiments of the present application, referring to Figure 5 The recognition module 150 may be a visual recognition module 150 and is used to photograph the side surface of the diaphragm 173 .

[0070] The visual recognition module 150 is responsible for identifying the expansion direction of the diaphragm 173 through image processing and analysis technology after photographing the side of the diaphragm 173. The visual recognition module 150 adopts advanced image recognition algorithms, which can accurately capture and identify subtle features of the diaphragm 173, thereby improving the accuracy of the recognition results. The visual recognition module 150 also has the ability to quickly capture and process images, and can complete the recognition task in a short time, reducing standby time.

[0071] In actual operation, when the lifting module 140 lifts the core 170 to be disassembled to a certain height, the visual recognition module 150 will start and photograph the side of the diaphragm 173. The image processing algorithm inside the module will analyze the captured image and identify the unfolding direction of the diaphragm 173. The recognition result will be sent to the lifting module 140 in real time to guide the rotating mechanism 142 to make necessary adjustments. Once the visual recognition module 150 completes the recognition and sends the adjustment instruction, the rotating mechanism 142 in the lifting module 140 will rotate the clamping mechanism 143 according to the instruction to make the unfolding direction of the diaphragm 173 consistent with the target direction. Then the lifting mechanism 141 will lift the adjusted core 170 to the required height to prepare for the subsequent diaphragm 173 winding step.

[0072] It can be understood that, by implementing the recognition module 150 as a visual recognition module 150 and photographing the side of the diaphragm 173 , the disassembling device 1 can accurately identify the unfolding direction of the diaphragm 173 , thereby further improving the disassembly efficiency and accuracy.

[0073] According to some embodiments of the present application, referring to Figure 1-Figure 3 , Figure 2 A schematic diagram of the structure of the diaphragm cutting module 120 provided in some embodiments of the present application. Figure 3 The schematic diagram of the structure of the membrane unfolding module 130 provided in some embodiments of the present application. The logistics line 110 includes: a feed line 111 and an opening and closing line 112 connected to each other; the membrane cutting module 120 is arranged on the feed line 111, and the membrane unfolding module 130, the lifting module 140, the identification module 150 and the membrane winding module 160 are arranged on the opening and closing line 112.

[0074] The feeding line 111 is the starting part of the logistics line 110, which is responsible for transporting the core 170 to be disassembled from the loading station to the disassembling equipment 1. The feeding line 111 is located at the entrance end of the disassembling equipment 1, and is connected to the opening and closing line 112. The opening and closing line 112 is located downstream of the feeding line 111, and is connected to the feeding line 111 to form a complete logistics line 110.

[0075] The opening and closing line 112 is the main part of the logistics line 110. It is responsible for carrying out subsequent disassembly steps after the feeding line 111 delivers the core 170 to its place. The opening and closing line 112 is arranged with multiple working modules, each of which is responsible for a specific disassembly task. Different working modules can be connected by robotic arms, conveyor belts or other transmission mechanisms to enable the core 170 to move smoothly between different workstations or modules.

[0076] The diaphragm cutting module 120 is arranged on the feeding line 111, and is responsible for cutting off the diaphragm 173 on the outer layer of the core 170. The diaphragm unfolding module 130 is arranged on the opening and closing line 112, and is located downstream of the diaphragm cutting module 120. It is responsible for unfolding the cut diaphragm 173 from the core 170. The lifting module 140 is also arranged on the opening and closing line 112, and is responsible for grabbing the core 170 with the diaphragm 173 unfolded, and lifting it to a certain height for subsequent identification and adjustment steps. The identification module 150 is also arranged on the opening and closing line 112, and is responsible for photographing and identifying the unfolding direction of the diaphragm 173, and sending the identification result to the lifting module 140. The diaphragm winding module 160 is arranged below the lifting module 140, and is responsible for winding up the diaphragm 173 unfolded from the core 170.

[0077] It can be understood that by subdividing the logistics line 110 into a feeding line 111 and an opening and closing line 112 , and clarifying the position of each module on the logistics line 110 , the disassembling device 1 can complete the disassembly task more efficiently, thereby improving the overall performance of the disassembling device 1 .

[0078] According to some embodiments of the present application, referring to Figure 3 The membrane unfolding module 130 includes: a scraping mechanism 131, a first driving mechanism 132, a clamping mechanism 133 and a second driving mechanism 134, which are responsible for completely unfolding the cut membrane 173 from the reel 170 to be disassembled, providing convenience for subsequent steps such as lifting, identification and winding.

[0079] The scraping mechanism 131 is in direct contact with the cut diaphragm 173 and initially unfolds the diaphragm 173 through horizontal movement. The scraping mechanism 131 can be designed in the form of a brush, a scraper or other shapes to enhance the effective contact between the scraping mechanism 131 and the cut diaphragm 173 .

[0080] The first driving mechanism 132 is power-coupled with the scraping mechanism 131 to provide power for the scraping mechanism 131 and drive the scraping mechanism 131 to move horizontally along the cut diaphragm 173. The first driving mechanism 132 can use a motor, a cylinder or other types of drivers to achieve continuous or intermittent movement of the scraping mechanism 131.

[0081] The clamping mechanism 133 is arranged on both sides of the scraping mechanism 131 to clamp the two ends of the cut diaphragm 173 to further unfold the diaphragm 173. The clamping mechanism 133 can adopt mechanical clamps, pneumatic clamps or other types of clamping devices to maintain a firm clamping of the cut diaphragm 173.

[0082] The second driving mechanism 134 is power-coupled to the clamping mechanism 133 to provide power to the clamping mechanism 133 to drive it to move to unfold the diaphragm 173. The second driving mechanism 134 is similar to the first driving mechanism 132 and can also be of different types to adapt to the specific movement requirements of the clamping mechanism 133.

[0083] When the core 170 to be disassembled reaches the diaphragm unfolding module 130, the scraping mechanism 131, driven by the first driving mechanism 132, moves horizontally along the cut diaphragm 173 to preliminarily unfold the diaphragm 173. At the same time or subsequently, the clamping mechanism 133, driven by the second driving mechanism 134, clamps the two ends of the cut diaphragm 173. Then the clamping mechanism 133 continues to move to completely unfold the cut diaphragm 173 through stretching or unfolding action. The unfolded core 170 is then transferred to the lifting module 140 for subsequent disassembly steps.

[0084] It can be understood that by integrating the scraping mechanism 131, the first driving mechanism 132, the clamping mechanism 133 and the second driving mechanism 134, the diaphragm unfolding module 130 can efficiently and accurately unfold the severed diaphragm 173, thereby improving the disassembly efficiency and maintaining the integrity and stability of the diaphragm 173 during the unfolding process.

[0085] According to some embodiments of the present application, referring to Figure 3 The scraping mechanism 131 includes a scraper or a rotatable brush.

[0086] The scraping mechanism 131 is a key component in the diaphragm unfolding module 130 and is responsible for directly contacting the severed diaphragm 173 and preliminarily unfolding the diaphragm 173 through its specific design. Specifically, the scraping mechanism 131 may include a scraper or a rotatable brush.

[0087] The scraper is usually made of a hard material, such as metal or hard plastic, so that it can form effective contact with the cut diaphragm 173 and exert sufficient force to unfold the diaphragm 173. When the scraper moves horizontally along the cut diaphragm 173 driven by the first driving mechanism 132, the scraper will scrape the surface of the diaphragm 173, thereby separating the diaphragm 173 from the core 170 to be disassembled and initially unfolding it.

[0088] The rotatable brush is composed of soft bristles and a supporting structure. The bristles can be natural fibers or synthetic fibers. When the brush is rotated under the drive of the first driving mechanism 132, the bristles will contact the cut diaphragm 173 and separate and unfold the diaphragm 173 through its soft characteristics and rotating action. Compared with a scraper, the brush is more suitable for processing more fragile or sensitive diaphragm 173 materials.

[0089] When the material of the diaphragm 173 is harder or thicker, a scraper can be selected, which can apply greater force to unfold the diaphragm 173. On the contrary, when the material of the diaphragm 173 is thinner or more fragile, a rotatable brush can be selected to avoid damaging the diaphragm 173 during the unfolding process.

[0090] It can be understood that by using a scraper or a rotatable brush as the scraping mechanism 131, the diaphragm unfolding module 130 can initially unfold the diaphragm 173 in a manner adapted to different diaphragm 173 materials and disassembly requirements, thereby improving the disassembly efficiency while maintaining the integrity and stability of the diaphragm 173 during the unfolding process.

[0091] According to some embodiments of the present application, referring to Figure 2 The diaphragm cutting module 120 can be one of hot cutting, cold cutting and laser cutting.

[0092] Thermal cutting mainly utilizes a high-temperature heat source to melt and cut off the diaphragm 173 , such as a heating wire. This method is usually suitable for thicker or tougher diaphragm 173 materials. If the diaphragm 173 material is thin, it may affect the pole piece under the diaphragm 173 .

[0093] Cold cutting mainly uses a mechanical blade or a shearing mechanism to cut the diaphragm 173 at room temperature. Cold cutting does not cause thermal damage and is usually suitable for thinner or more fragile diaphragm 173 materials.

[0094] Laser cutting mainly utilizes a high-energy laser beam to quickly cut off the diaphragm 173. Laser cutting has the advantages of high precision, high speed and low contact force, and is suitable for diaphragm 173 materials of various thicknesses.

[0095] The membrane cutting module 120 is responsible for cutting off the outer membrane 173 of the core 170 to be disassembled during the disassembly process, and may adopt one or more of the above three cutting methods, depending on the material of the membrane 173 of the core 170 to be disassembled and the disassembly requirements.

[0096] According to some embodiments of the present application, referring to Figure 2 The diaphragm cutting module 120 includes a lifting mechanism 121 and an actuator 122 , and the actuator 122 is installed on the lifting mechanism 121 .

[0097] The lifting mechanism 121 is responsible for lifting the actuator 122 to a suitable height so as to contact the diaphragm 173 of the winding core 170 to be disassembled. The lifting mechanism 121 can use a motor, a cylinder, a hydraulic cylinder or other types of drivers to achieve vertical movement.

[0098] The actuator 122 is installed on the lifting mechanism 121 and is responsible for actually executing the cutting action. The actuator 122 may include cutting elements such as a blade, a heating wire, a laser emitter, and a corresponding driving mechanism and control system.

[0099] When the roll core 170 to be disassembled is conveyed to the diaphragm cutting module 120, the lifting mechanism 121 lifts the actuator 122 to an appropriate height, and then the actuator 122 starts to work to cut the diaphragm 173 according to the selected cutting method. After the cutting is completed, the lifting mechanism 121 lowers the actuator 122 back to its original position for the next cutting operation. The cut diaphragm 173 is then transferred to the diaphragm unfolding module 130 for subsequent disassembly steps.

[0100] According to some embodiments of the present application, referring to Figure 2 The diaphragm cutting module 120 can be one of hot cutting, cold cutting and laser cutting. The diaphragm cutting module 120 includes a lifting mechanism 121 and an actuator 122 , and the actuator 122 is installed on the lifting mechanism 121 .

[0101] The lifting mechanism 121 is responsible for lifting the actuator 122 to a suitable height so as to contact the diaphragm 173 of the winding core 170 to be disassembled. The lifting mechanism 121 can use a motor, a cylinder, a hydraulic cylinder or other types of drivers to achieve vertical movement.

[0102] The actuator 122 is installed on the lifting mechanism 121 and is responsible for actually executing the cutting action. The actuator 122 may include cutting elements such as a blade, a heating wire, a laser emitter, and a corresponding driving mechanism and control system.

[0103] When the core 170 to be disassembled is conveyed to the diaphragm cutting module 120, the lifting mechanism 121 lifts the actuator 122 to an appropriate height, and then the actuator 122 starts to work to cut the diaphragm 173 according to the selected cutting method, such as hot cutting, cold cutting and laser cutting. After the cutting is completed, the lifting mechanism 121 lowers the actuator 122 back to its original position for the next cutting operation. The cut diaphragm 173 is then transferred to the diaphragm unfolding module 130 for subsequent disassembly steps.

[0104] It can be understood that by adopting one or more cutting methods including hot cutting, cold cutting or laser cutting, and combining the lifting mechanism 121 and the actuator 122, the diaphragm cutting module 120 can efficiently cut the diaphragm 173 on the outer layer of the core 170 to be disassembled.

[0105] According to some embodiments of the present application, referring to Figure 6 , Figure 6The structure diagram of the membrane winding module 160 provided in some embodiments of the present application. The membrane winding module 160 includes: a reel 161, a third driving mechanism 162, a material receiving bracket 163 and a fourth driving mechanism 164. The third driving mechanism 162 is coupled to the reel 161 by power, and is used to drive the reel 161 to rotate; the material receiving bracket 163 includes a clamping plate 165 sleeved outside the reel 161 and a material receiving plate 166 located below the reel 161; the fourth driving mechanism 164 is coupled to the material receiving bracket 163 by power, and is used to drive the material receiving bracket 163 to move along the reel 161.

[0106] The diaphragm winding module 160 is responsible for neatly winding the unfolded diaphragm 173 onto the reel 161 for subsequent processing or recycling, wherein the reel 161 is the core component for winding the diaphragm 173 and is used to carry and wind the unfolded diaphragm 173. The reel 161 is usually cylindrical in design, and the surface can be specially treated to increase the friction between the diaphragm 173 and reduce the risk of the diaphragm 173 slipping during the winding process.

[0107] The third driving mechanism 162 is power-coupled with the reel 161 to provide power for the reel 161 and drive the reel 161 to rotate to wind the diaphragm 173. The third driving mechanism 162 can use a motor, a reducer or other equipment to enable the reel 161 to rotate at a constant speed or according to a preset program.

[0108] The material receiving bracket 163 includes a clamping plate 165 sleeved on the outside of the reel 161 and a material receiving plate 166 located below the reel 161, which are used to support and guide the unfolded diaphragm 173 so that it can be stably wound on the reel 161. The clamping plate 165 is sleeved on the outside of the reel 161, which is used to limit the lateral movement of the diaphragm 173 during the winding process, so that the diaphragm 173 can be tightly wound on the reel 161 and the wound diaphragm 173 can be separated from the reel 161. The material receiving plate 166 is located below the reel 161 and is used to receive the wound diaphragm 173 separated from the reel 161.

[0109] The fourth driving mechanism 164 is power-coupled with the material receiving bracket 163 to provide power for the material receiving bracket 163 and drive the material receiving bracket 163 to move along the reel 161 so that the wound diaphragm 173 can be separated from the reel 161. The fourth driving mechanism 164 can adopt transmission mechanisms such as slide rails, cylinders, and screws to enable the material receiving bracket 163 to move smoothly and accurately.

[0110] When the unfolded diaphragm 173 is transferred from the diaphragm unfolding module 130 to the diaphragm winding module 160, the reel 161 first receives the diaphragm 173 and winds it along the reel 161. At the same time, the third driving mechanism 162 starts to work, driving the reel 161 to rotate to wind the diaphragm 173. After the diaphragm 173 is wound, the fourth driving mechanism 164 drives the material receiving bracket 163 to move along the reel 161 so that the wound diaphragm 173 is separated from the reel 161 and falls onto the material receiving plate 166.

[0111] It can be understood that by integrating the reel 161, the third drive mechanism 162, the material receiving bracket 163 and the fourth drive mechanism 164, the diaphragm winding module 160 can efficiently collect and organize the unfolded diaphragm 173, thereby improving the disassembly efficiency and improving the integrity and stability of the diaphragm 173 during the winding process.

[0112] According to some embodiments of the present application, referring to Figure 6 The membrane winding module 160 has various structural forms, including but not limited to: In example 1, the diaphragm winding module 160 is of a needle-threading type.

[0113] At the same time, the disassembling equipment 1 includes a clamping mechanism 143 for clamping the diaphragm 173 that droops after the core 170 to be disassembled is lifted. The clamping mechanism 143 can move vertically and is responsible for clamping the diaphragm 173 that droops after the core 170 to be disassembled is lifted, so as to tension the diaphragm 173 and guide the diaphragm 173 to the reel 161 of the needle-threading diaphragm winding module 160.

[0114] One end of the reel 161 of the needle-threading diaphragm winding module 160 is provided with a groove that passes through the reel 161, and the groove can serve as a guide channel for the diaphragm 173, so that the diaphragm 173 is clamped on the reel 161, and then the reel 161 starts to wind up, and one end of the diaphragm 173 is fixed on the reel 161, and gradually winds up with the rotation of the reel 161, thereby maintaining the stability and consistency of the winding quality.

[0115] The needle-threading design can accurately control the winding position and winding method of the diaphragm 173, so that the diaphragm 173 can be tightly and evenly wound on the winding device.

[0116] Example 2: The diaphragm winding module 160 is of negative pressure type.

[0117] The negative pressure diaphragm winding module 160 utilizes negative pressure suction to adsorb the unfolded diaphragm 173 onto the reel 161, and realizes the winding of the diaphragm 173 by rotating the winding device. The reel 161 of the negative pressure diaphragm winding module 160 is provided with a plurality of negative pressure air holes, and negative pressure is generated by the negative pressure device. Then the reel 161 rotates under the drive of the motor to gradually wind up the material adsorbed on the conveying device.

[0118] In addition, when using the negative pressure winding module, attention should be paid to the sealing between the winding device and the diaphragm 173 to reduce the risk of negative pressure suction failure or the diaphragm 173 slipping during the winding process.

[0119] By combining negative pressure adsorption with the winding of the diaphragm 173 , the diaphragm 173 can be kept flat and stable during the conveying and winding process, thereby improving the winding efficiency and quality.

[0120] According to some embodiments of the present application, the disassembly equipment 1 further includes: a pole piece storage box, which is arranged below the lifting module 140 .

[0121] The main function of the electrode storage box is to receive and store the electrodes separated and dropped from the core 170 to be disassembled. These electrodes are key components in lithium-ion batteries and have a high recycling value. The electrode storage box is arranged under the lifting module 140. When the lifting module 140 lifts the core 170 to be disassembled and unfolds the diaphragm 173, the electrode can fall smoothly into the storage box without additional transmission or moving steps. The electrode storage box usually has a large capacity to accommodate multiple electrodes separated from the core 170 to be disassembled. The electrode storage box can also be movable to facilitate transportation.

[0122] When the core 170 to be disassembled is transported to the lifting module 140 of the disassembling equipment 1, the lifting module 140 starts to work and lifts the core 170 to an appropriate height. Then the diaphragm unfolding module 130 starts to unfold the diaphragm 173 to expose the internal pole pieces. The pole pieces fall into the pole piece storage box below under the action of gravity. When the storage box is full or reaches the predetermined disassembly quantity, the operator moves the storage box out of the disassembly equipment 1 and recycles and processes the pole pieces therein subsequently.

[0123] It can be understood that the electrode storage box can store the electrode separated from the winding core 170 to be disassembled safely and orderly, which helps to improve the disassembly efficiency.

[0124] According to some embodiments of the present application, see Figure 1-Figure 6 As shown, the present application provides a disassembly device 1, which is used for disassembling a single roll core 170, including: a logistics line 110, a diaphragm cutting module 120, a diaphragm unfolding module 130, a lifting module 140, an identification module 150, a diaphragm winding module 160 and a pole piece storage box.

[0125] The logistics line 110 is used to transport the core 170 to be disassembled, and the logistics line 110 includes a feeding line 111 and an opening and closing line 112 that are connected to each other. The diaphragm cutting module 120 is arranged on the feeding line 111, and the diaphragm unfolding module 130, the lifting module 140, the identification module 150 and the diaphragm winding module 160 are arranged on the opening and closing line 112.

[0126] The diaphragm cutting module 120 is arranged along the logistics line 110, and is used to cut the diaphragm 173 on the outer layer of the core 170 to be disassembled. The diaphragm cutting module 120 can be one of hot cutting, cold cutting and laser cutting. The diaphragm cutting module 120 includes a lifting mechanism 121 and an actuator 122, and the actuator 122 is installed on the lifting mechanism 121.

[0127] The diaphragm unfolding module 130 is arranged along the logistics line 110, and is used to unfold the cut diaphragm 173 from the core 170 to be disassembled. The diaphragm unfolding module 130 includes: a scraping mechanism 131, a first driving mechanism 132, a clamping mechanism 133 and a second driving mechanism 134. The scraping mechanism 131 includes a scraper or a rotatable brush for abutting the cut diaphragm 173. The first driving mechanism 132 is power-coupled with the scraping mechanism 131 to drive the scraping mechanism 131 to move along the cut diaphragm 173. The clamping mechanism 133 is arranged on both sides of the scraping mechanism 131 to clamp the two ends of the cut diaphragm 173. The second driving mechanism 134 is power-coupled with the clamping mechanism 133 to drive the clamping mechanism 133 to move to unfold the diaphragm 173.

[0128] The lifting module 140 is arranged along the logistics line 110, and is used to grab the unrolled diaphragm 173 and lift it. The lifting module 140 can also be used to loosen the core 170 to be disassembled when the diaphragm winding module 160 winds up the diaphragm 173, so as to separate the diaphragm 173 from the pole piece when the core 170 to be disassembled falls.

[0129] The lifting module 140 includes: a lifting mechanism 141, a rotating mechanism 142 installed on the lifting mechanism 141 and a clamping mechanism 143 installed on the rotating mechanism 142. When the recognition result indicates that the unfolding direction of the diaphragm 173 of the core 170 to be disassembled is opposite to the target direction, the rotating mechanism 142 is used to rotate the clamping mechanism 143 until the unfolding direction of the diaphragm 173 is consistent with the target direction. The pole piece storage box is arranged below the clamping mechanism 143 of the lifting module 140, and is used to receive and store the pole pieces separated and dropped from the core 170 to be disassembled.

[0130] The identification module 150 is arranged along the logistics line 110, and is used to identify the unfolding direction of the core 170 to be disassembled when the lifting module 140 lifts the core 170 to be disassembled, and send the identification result to the lifting module 140. The identification module 150 can be a visual recognition module 150, and is used to photograph the side of the diaphragm 173.

[0131] The diaphragm winding module 160 is arranged along the logistics line 110, and is used to wind up the diaphragm 173. The diaphragm winding module 160 includes: a reel 161, a third driving mechanism 162, a material receiving bracket 163 and a fourth driving mechanism 164. The third driving mechanism 162 is power-coupled with the reel 161 to drive the reel 161 to rotate. The material receiving bracket 163 includes a clamping plate 165 mounted outside the reel 161 and a material receiving plate 166 located below the reel 161. The fourth driving mechanism 164 is power-coupled with the material receiving bracket 163 to drive the material receiving bracket 163 to move along the reel 161.

[0132] The diaphragm winding module 160 may be of a needle-threading type, and the disassembling device 1 includes a clamping mechanism 143 for clamping the sagging diaphragm 173 after the core 170 to be disassembled is lifted, or the diaphragm winding module 160 may be of a negative pressure type.

[0133] In the actual working process, the diaphragm cutting module 120 cuts off the diaphragm 173 of the outer layer of the core 170 on the feeding line 111, and the core 170 continues to move along the opening and closing line 112 to reach the diaphragm unfolding module 130. The diaphragm unfolding module 130 unfolds the diaphragm 173 from the core 170 through the scraping mechanism 131. The lifting module 140 grabs the core 170 with the unfolded diaphragm 173 and lifts it to a certain height. Then the recognition module 150 photographs and recognizes the unfolding direction of the diaphragm 173. The recognition result is sent to the lifting module 140. If adjustment is needed, the rotating mechanism 142 in the lifting module 140 will rotate the clamping mechanism 143 to the correct direction. The adjusted winding core 170 and the diaphragm 173 sag, and the diaphragm winding module 160 starts to wind up the unfolded diaphragm 173. During the winding process of the diaphragm 173, the lifting module 140 releases the winding core 170, so that the winding core 170 separates the diaphragm 173 and the pole piece when it falls, and the pole piece falls into the pole piece storage box below under the action of gravity.

[0134] Unless otherwise specified, all technical features and optional technical features of this application can be combined with each other to form a new technical solution.
