Description

Technical Field

[0001] The present invention relates to the technical field of battery electrode sheet separation and recycling, and specifically provides a battery core positive and negative electrode sheet separation device. Background Art

[0002] A battery core is formed by winding battery electrode sheets. A battery electrode sheet is composed of a positive electrode sheet, a negative electrode sheet, and two layers of separator membranes. The positive electrode sheet and the negative electrode sheet are separated by the two layers of separator membranes, such that the positive electrode sheet is adhered between the two layers of separator membranes, and the negative electrode sheet is adhered to one layer. During the process of recycling batteries, the recycling of battery electrode sheets requires a separation device to separate and recycle the positive electrode sheet, the negative electrode sheet, and the two layers of separator membranes.

[0003] Application No.: 202410446979.9, Invention Title: A Battery Core Separation Device, is an invention patent applied by our company for the automatic separation of battery cores. This application realizes the purpose of automatically separating the positive electrode sheet, the negative electrode sheet, and the two layers of separator membranes through the cooperation of a loose coil assembly, a negative electrode separation assembly, and a positive electrode and separator membrane separation assembly, and solves the problem of low automation degree of battery electrode sheet separation on the market.

[0004] However, during the subsequent actual operation of our company's equipment, it was found that during the separation process of existing separation equipment for old battery electrode sheets, due to the presence of many cracks in the old electrode sheets themselves, they are prone to breakage during the pulling process, which in turn leads to the inability to complete the separation operation. It is necessary to manually continuously connect the broken parts of the electrode sheets, resulting in low separation efficiency and low separation completion rate. Therefore, our company has proposed a battery core positive and negative electrode sheet separation device to solve the above technical problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a battery core positive and negative electrode sheet separation device to solve the problems raised in the background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A battery core positive and negative electrode sheet separation device includes a bottom plate, on which a battery core separation device is provided. The battery core separation device is used for separating and recycling battery cores and battery electrode sheets. The battery electrode sheets include a positive electrode sheet, a separator membrane, and a negative electrode sheet. The battery core separation device includes an anti-breakage mechanism.

[0007] The anti-breakage mechanism includes a rotation assembly, a driving assembly, a visual detection assembly, and a connection assembly. The rotation assembly is fixedly installed on the upper side of the bottom plate through a bracket. Two connection assemblies are fixedly installed on the rotation assembly. On the side of the connection assembly away from the center of the rotation assembly, a driving assembly and a visual detection assembly are fixedly connected.

[0008] The rotating component can drive the driving component, the visual detection component, and the connecting component to perform circular motion. The visual detection component can detect the newness of the battery pole piece, so that the driving component can adaptively control the transportation of the battery pole piece and connect the broken battery pole piece.

[0009] Furthermore, the rotating assembly includes an annular track, a chain, a sprocket, a motor 1, a bearing plate, and a hydraulic cylinder 2. The upper side of the base plate is fixedly connected to the hydraulic cylinder 2 via a bracket, the output end of the hydraulic cylinder 2 is fixedly connected to the bearing plate, the bearing plate is fixedly connected to the motor 1, a annular track is provided on the side of the bearing plate away from the hydraulic cylinder 2, four groups of sprockets are rotatably connected to the annular track, chains are meshed on the outer sides of the sprockets, one end of one group of sprockets is fixedly connected to the output end of the motor 1, and the other three groups of sprockets are connected to the bearing plate via fixed shafts.

[0010] Furthermore, the connecting assembly includes a connecting plate, a roller, a mounting plate, and a connecting block. Two groups of connecting blocks are fixedly connected to the outer side of the chain. The end of the connecting block away from the chain is fixedly connected to the mounting plate. The mounting plate is rotatably connected to the roller. An annular groove corresponding to the roller is opened on the annular track. The roller slides in the annular groove. The side of the mounting plate away from the connecting block is fixedly connected to the connecting plate.

[0011] When the battery pole piece is broken, the separation operation stops, and the fixed negative pressure chamber and the mobile negative pressure chamber are controlled to firstly absorb the battery pole piece with a smaller adsorption force, and move forward at the same time, thereby driving the battery pole piece to be flattened and straightened. When the CCD camera moves to the place where the battery pole piece is broken, the adsorption force is increased, and then the battery pole piece is pulled to connect with the two sets of vacuum adsorption rollers, thereby realizing the connection operation of the broken battery pole piece;

[0012] Furthermore, the driving assembly includes a fixed negative pressure chamber, a mobile negative pressure chamber, a guide pipe, an air duct, and a driving assembly. The fixed negative pressure chamber is fixedly connected to the side of the connecting plate away from the mounting plate. Two groups of mobile negative pressure chambers are slidably connected to the inner side of the fixed negative pressure chamber. The mobile negative pressure chamber is connected to a guide pipe, which passes through the inner side wall of the fixed negative pressure chamber and extends into the inner side of the fixed negative pressure chamber to communicate with it. The middle part of the fixed negative pressure chamber is connected to the air duct, and the outer side of the fixed negative pressure chamber is provided with a driving assembly.

[0013] When it is recognized that there are many cracks in the battery electrode sheet and it is relatively old, the fixed negative pressure chamber and the moving negative pressure chamber are moved into contact with the battery electrode sheet. Since the air duct is connected to an external negative pressure mechanism, the fixed negative pressure chamber is formed into a negative pressure state. Through the conduction of the guide pipe, the inside of the moving negative pressure chamber is also formed into a negative pressure state. Since the contact surfaces of the fixed negative pressure chamber and the moving negative pressure chamber with the battery electrode sheet are both provided with uniformly distributed through holes, the fixed negative pressure chamber and the moving negative pressure chamber adsorb the battery electrode sheet. At the same time, the first motor is started, and the first motor drives the sprocket to rotate. Then the sprocket meshes to drive the chain to perform a circular motion, and the chain drives the driving assembly, the visual inspection assembly, and the connecting assembly to perform a circular motion, so as to follow the movement of the battery electrode sheet. Therefore, when separating the relatively old battery electrode sheet, it provides transportation assistance to prevent it from breaking due to excessive tension.

[0014] The driving assembly includes a second motor, a fixed seat, a first bidirectional lead screw, and a first slider. Two groups of second motors are fixedly connected to the outside of the moving negative pressure chamber. The output end of the second motor is fixedly connected to the first bidirectional lead screw. The first bidirectional lead screw is fixedly installed on the outside through a bearing with a fixed seat, and the fixed seat is fixedly connected to the fixed negative pressure chamber. Two groups of first sliders are threadedly connected to the outside of the first bidirectional lead screw. One end of the first slider is fixed to the moving negative pressure chamber, and a chute corresponding to the first slider is provided on the fixed negative pressure chamber.

[0015] For the unrolled battery electrode sheet, control the start of the second motor. The second motor drives the first bidirectional lead screw to rotate. While the first bidirectional lead screw is rotating, it drives the first slider to slide outwards, thereby driving the moving negative pressure chamber to move outwards, so as to perform the unfolding operation on the battery electrode sheet and ensure the normal operation of the separation operation.

[0016] Furthermore, the visual inspection assembly includes a connecting seat, a CCD camera, and a light source. A connecting seat is fixedly connected to the connecting plate. A CCD camera is fixedly connected to one side of the connecting seat, and a light source is fixedly connected to the upper side of the connecting seat.

[0017] Start the second hydraulic cylinder, and the second hydraulic cylinder drives the annular track to move downwards, so that the driving assembly and the visual inspection assembly approach the battery electrode sheet. Through the cooperation of the light source and the CCD camera, the surface of the continuously advancing battery electrode sheet is photographed, achieving the purpose of detecting the cracks on the surface of the battery electrode sheet. Through the photographed image information, the external system can identify whether there are cracks, and then can judge the newness and oldness of the battery electrode sheet.

[0018] Further, the battery core separation device further includes an attitude adjustment mechanism, a tension adjustment mechanism, a tension detection mechanism, and a clamping and conveying mechanism. The attitude adjustment mechanism includes a hydraulic motor 1, a fixed plate, a connecting platform, a transmission gear, a driving gear, a movable plate, and a rotating gear. A connecting bottom plate is provided on the side of the anti-breaking mechanism away from the bottom plate. A movable plate is provided on the lower side of the connecting bottom plate. A tension detection mechanism is fixedly installed on the movable plate. One side of the tension detection mechanism away from the movable plate is fixedly connected to a connecting platform. One side of the connecting platform away from the movable plate is fixedly connected to a rotating gear. The outside of the rotating gear is engaged with a transmission gear. The outside of the transmission gear is engaged with a driving gear. The transmission gear and the driving gear are provided with a fixed plate on the side away from the movable plate. The fixed plate is fixedly connected with a hydraulic motor 1. The output end of the hydraulic motor 1 is fixedly connected to the driving gear. The inner side of the transmission gear is rotatably connected to a connecting shaft, and the connecting shaft is fixedly connected to the fixed plate.

[0019] Start the hydraulic motor 1. The hydraulic motor 1 drives the driving gear to rotate. The driving gear drives the transmission gear through meshing. The transmission gear drives the rotating gear through meshing, thereby driving the movable plate and the mechanisms on the movable plate to rotate synchronously, making the folding angle of the battery pole piece larger. The older the battery pole piece is, the larger the folding angle of the battery pole piece is, further avoiding the possibility of the battery pole piece breaking.

[0020] Further, the tension adjustment mechanism includes a collection chamber, an adjustment roller, a cleaning roller, a driving member, a hydraulic motor 2, and a hydraulic cylinder 1. The connecting bottom plate is fixedly connected to the hydraulic cylinder 1 through a rectangular block. The output end of the hydraulic cylinder 1 is fixedly connected to the hydraulic motor 2. The output end of the hydraulic motor 2 is fixedly connected to the adjustment roller and the cleaning roller. One end of the adjustment roller and the cleaning roller is connected to the driving member through a bearing. The driving member is fixedly connected to the hydraulic motor 2. A slot corresponding to the driving member is provided on the connecting bottom plate.

[0021] Adjust the running speed of the battery pole piece according to its newness and oldness. If the battery pole piece is relatively new, the running speed is relatively fast. If the battery pole piece is relatively old, the running speed is relatively slow. At the same time, adjust its tension. The tension sensor can detect the tension when the battery pole piece is separated. By controlling the extension and retraction of the hydraulic cylinder 1, the tension can be controlled to become smaller and larger, so that if the battery pole piece is relatively new, the tension is relatively large. If the battery pole piece is relatively old, the tension is relatively small. At the same time, when the hydraulic motor 2 drives the adjustment roller and the cleaning roller to rotate, since the cleaning roller is provided with evenly distributed bristles, the adjustment roller can be cleaned, so that the negative residue can be cleaned and collected into the collection chamber.

[0022] Further, the tension detection mechanism includes a guide roller and a tension sensor. The guide roller is fixedly installed on the movable plate. One end of the guide roller away from the movable plate is provided with a tension sensor.

[0023] The clamping and conveying mechanism includes a regulating component and a vacuum adsorption roller. A moving component is fixedly connected to one side of the connecting bottom plate close to the anti-breaking mechanism. The output end of the moving component is fixedly connected to the regulating component. The regulating component includes a guide rail, a motor three, a bidirectional lead screw two, a mounting seat, a slider two, and a bearing seat. The output end of the moving component is fixedly connected to two groups of guide rails through a straight plate. A motor three is fixedly connected to the inner side of the guide rail. The output end of the motor three is fixedly connected to the bidirectional lead screw two. The bidirectional lead screw two is connected to the mounting seat through a bearing. The mounting seat is fixed to the guide rail. Two groups of sliders two are threadedly connected to the outer side of the bidirectional lead screw two. The slider two slides on the guide rail. One side of the slider two is fixedly connected to the bearing seat. The inner side of the bearing seat is connected to the vacuum adsorption roller through a bearing.

[0024] Start the motor three. The motor three drives the bidirectional lead screw two to rotate. During the rotation of the bidirectional lead screw two, the vacuum adsorption rollers are driven to separate from each other through the slider two and the bearing seat, so that the two vacuum adsorption rollers move to the outside of the first layer where the core is broken. Then control the motor three to reverse, and the two vacuum adsorption rollers clamp and hold the first layer where the core is broken.

[0025] Furthermore, the battery core separation device further includes a flipping and peeling mechanism, a negative electrode collection mechanism, a separation mechanism, and a core film peeling component. A flipping and peeling mechanism, a negative electrode collection mechanism, and a separation mechanism are fixedly connected to the bottom plate. The separation mechanism includes a guide roller group, a cutting die component, a film suction component, and a peeling part. Two groups of guide roller groups are rotatably connected to the movable plate. The cutting die component is arranged on the outer side of the guide roller group. The cutting die component is fixed to the movable plate. The film suction components are arranged on both sides of the lower part of the guide roller group. The film suction components are fixed to the movable plate. A peeling part is fixedly installed on the upper side of the negative electrode collection mechanism.

[0026] The flipping and peeling mechanism lifts the core to have enough flipping space. The two vacuum adsorption rollers clamp one end of the battery electrode plate and continuously pull it forward. Since the negative electrode plate is relatively short, it is peeled off by the peeling part and automatically falls into the negative electrode collection mechanism. The two vacuum adsorption rollers pull the positive electrode plate and the diaphragm to move to the initial position.

[0027] Two groups of core film peeling components are also fixedly connected to the movable plate. The core film peeling components correspond to the film suction components.

[0028] The end of the diaphragm is blown to the die cutting assembly by the blowing assembly, and the die cutting assembly cuts off the excess part of the end. Then the positive electrode sheet and the diaphragm are guided to the film suction assembly by the guide roller group. The film suction assembly is controlled to start to approach the diaphragm to adsorb it, and then rotate to separate the two layers of diaphragm from the positive electrode sheet. The separated diaphragm is clamped by the external clamping claw. Since the external clamping claw sleeves the diaphragm on the optical axis of the roll stripping assembly, the roll stripping assembly rotates, and then continuously winds the diaphragm on the optical axis of the roll stripping assembly, thereby realizing the separation and recovery of the positive electrode sheet, diaphragm, and negative electrode sheet;

[0029] Furthermore, a stripping assembly corresponding to the flipping and stripping mechanism is fixedly connected to the bottom plate, and a blowing assembly corresponding to the battery pole piece is fixedly connected to the connecting bottom plate.

[0030] The battery roll core to be separated is placed in the clamping part of the flipping and peeling mechanism for clamping. The first layer of the roll core is opened by the peeling component, and then the moving component is started. The moving component drives the clamping and conveying mechanism to move to the loading position.

[0031] Compared with the prior art, the present invention provides a battery core positive and negative electrode sheet separation device, which has the following beneficial effects:

[0032] 1. The battery core positive and negative electrode separation equipment realizes the purpose of multi-stage auxiliary driving separation operation on old electrodes through the cooperation between the posture adjustment mechanism, the tension adjustment mechanism, the tension detection mechanism, the anti-breakage mechanism, and the clamping and conveying mechanism. It adaptively controls the auxiliary driving force, the auxiliary driving fulcrum, and the automatic adjustment of the electrode angle. According to the degree of age of the electrode, the separation tension of the electrode is automatically adjusted, which greatly reduces the possibility of electrode breakage and solves the problem that the old electrode has many cracks and is easy to break during the pulling process, which leads to the inability to complete the separation operation and requires manual connection of the broken electrode parts, resulting in low separation efficiency and low separation completion.

[0033] 2. The battery core positive and negative electrode separation equipment, through the cooperation of light source and CCD camera, can capture images of the surface of the continuously moving battery electrode, thereby achieving the purpose of detecting cracks on the surface of the battery electrode. Through the captured image information, the external system can identify whether there are cracks, and then judge the newness of the battery electrode. At the same time, when the battery electrode is broken, the broken battery electrode can be connected, realizing fully automated operation and high separation operation completion.

[0034] 3. The battery core positive and negative electrode separation equipment can automatically control the posture adjustment mechanism angle, not only can it adaptively adjust the folding angle of the electrode according to the age of the electrode, but also can freely adjust the separation and collection position according to needs, thereby meeting different needs and achieving a wide range of applications.

[0049] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0050] Embodiment

[0051] Please refer to Figures 1 - 13 , a positive and negative electrode plate separation device for a battery core, including a bottom plate 1, a battery core separation device is arranged on the bottom plate 1, and the battery core separation device is used for separating and recycling the battery core and the battery electrode plate 6. The battery electrode plate 6 includes a positive electrode plate 61, a diaphragm 62, and a negative electrode plate 63. The battery core separation device includes an anti-breaking mechanism 7;

[0052] The anti-breaking mechanism 7 includes a rotating assembly 71, a driving assembly 72, a vision detection assembly 73, and a connecting assembly 74. The rotating assembly 71 is fixedly installed on the upper side of the bottom plate 1 through a bracket. Two groups of connecting assemblies 74 are fixedly installed on the rotating assembly 71. On the side of the connecting assembly 74 away from the center of the rotating assembly 71, a driving assembly 72 and a vision detection assembly 73 are fixedly connected;

[0053] The rotating assembly 71 can drive the driving assembly 72, the vision detection assembly 73, and the connecting assembly 74 to perform circular motion. The vision detection assembly 73 can detect the degree of newness and oldness of the battery electrode plate 6, so that the driving assembly 72 adaptively adjusts to drive the transportation of the battery electrode plate 6 and connect the broken battery electrode plate 6.

[0054] Furthermore, the rotating assembly 71 includes an annular track 711, a chain 712, a sprocket 713, a first motor 714, a bearing plate 715, and a second hydraulic cylinder 716. The second hydraulic cylinder 716 is fixedly connected to the upper side of the bottom plate 1 through a bracket. The output end of the second hydraulic cylinder 716 is fixedly connected to the bearing plate 715. The first motor 714 is fixedly connected to the bearing plate 715. An annular track 711 is arranged on the side of the bearing plate 715 away from the second hydraulic cylinder 716. Four groups of sprockets 713 are rotatably connected to the annular track 711. The outside of the sprocket 713 is engaged with the chain 712. One end of a group of sprockets 713 is fixedly connected to the output end of the first motor 714, and the other three groups of sprockets 713 are connected to the bearing plate 715 through a fixed shaft.

[0055] Furthermore, the connecting assembly 74 includes a connecting plate 741, a roller 742, a mounting plate 743, and a connecting block 744. Two groups of connecting blocks 744 are fixedly connected to the outside of the chain 712. One end of the connecting block 744 away from the chain 712 is fixedly connected to the mounting plate 743. The roller 742 is rotatably connected to the mounting plate 743. An annular groove corresponding to the roller 742 is formed on the annular track 711. The roller 742 slides in the annular groove. The connecting plate 741 is fixedly connected to the side of the mounting plate 743 away from the connecting block 744.

[0056] When the battery electrode plate 6 breaks, the separation operation stops at this time. The fixed negative pressure chamber 721 and the moving negative pressure chamber 722 are controlled to adsorb the battery electrode plate 6 with a relatively small adsorption force first, and move forward at the same time, thereby driving the battery electrode plate 6 to be flattened and straightened. When the CCD camera 732 moves to the broken part of the battery electrode plate 6, the adsorption force is increased, and then the battery electrode plate 6 is pulled to be docked with the two vacuum adsorption rollers 82, thereby realizing the connection operation of the broken battery electrode plate 6;

[0057] Further, the driving assembly 72 includes a fixed negative pressure chamber 721, a movable negative pressure chamber 722, a guiding pipe 723, an air duct 724, and a driving assembly 725. On the side of the connecting plate 741 away from the mounting plate 743, a fixed negative pressure chamber 721 is fixedly connected. Inside the fixed negative pressure chamber 721, two groups of movable negative pressure chambers 722 are slidably connected. A guiding pipe 723 is communicated with the movable negative pressure chamber 722. The guiding pipe 723 penetrates the inner wall of the fixed negative pressure chamber 721 and extends into the inside of the fixed negative pressure chamber 721 to be in communication with it. In the middle of the fixed negative pressure chamber 721, an air duct 724 is communicated. Outside the fixed negative pressure chamber 721, a driving assembly 725 is arranged.

[0058] When it is recognized that there are many cracks and the battery electrode plate 6 is relatively old, the fixed negative pressure chamber 721 and the movable negative pressure chamber 722 are moved into contact with the battery electrode plate 6. Since the air duct 724 is communicated with an external negative pressure mechanism, the fixed negative pressure chamber 721 is formed into a negative pressure state. Through the conduction of the guiding pipe 723, the inside of the movable negative pressure chamber 722 is also formed into a negative pressure state. Since the contact surfaces of the fixed negative pressure chamber 721 and the movable negative pressure chamber 722 with the battery electrode plate 6 are provided with uniformly distributed through holes, the fixed negative pressure chamber 721 and the movable negative pressure chamber 722 adsorb the battery electrode plate 6. At the same time, the first motor 714 is started. The first motor 714 drives the sprocket 713 to rotate, and then the sprocket 713 meshes with and drives the chain 712 to perform a circular motion. The chain 712 drives the driving assembly 72, the visual detection assembly 73, and the connecting assembly 74 to perform a circular motion, so as to move along with the battery electrode plate 6. When separating the relatively old battery electrode plate 6, it provides transportation assistance and driving to prevent it from breaking due to excessive tension.

[0059] The driving assembly 725 includes a second motor 7251, a fixed seat 7252, a first bidirectional lead screw 7253, and a first slider 7254. Two groups of second motors 7251 are fixedly connected to the outside of the movable negative pressure chamber 722. The output end of the second motor 7251 is fixedly connected to a first bidirectional lead screw 7253. The outside of the first bidirectional lead screw 7253 is fixedly installed with a fixed seat 7252 through a bearing. The fixed seat 7252 is fixedly connected to the fixed negative pressure chamber 721. Two groups of first sliders 7254 are threadedly connected to the outside of the first bidirectional lead screw 7253. One end of the first slider 7254 is fixed to the movable negative pressure chamber 722. A chute corresponding to the first slider 7254 is opened on the fixed negative pressure chamber 721.

[0060] For the unrolled battery electrode plate 6, control the start of the second motor 7251. The second motor 7251 drives the first bidirectional lead screw 7253 to rotate. While the first bidirectional lead screw 7253 is rotating, it drives the first slider 7254 to slide outwards, thereby driving the movable negative pressure chamber 722 to move outwards, so as to perform a stretching operation on the battery electrode plate 6 and ensure the normal operation of the separation operation.

[0061] Further, the visual detection component 73 includes a connecting seat 731, a CCD camera 732, and a light source 733. The connecting seat 731 is fixedly connected to the connecting plate 741. One side of the connecting seat 731 is fixedly connected to the CCD camera 732, and the upper side of the connecting seat 731 is fixedly connected to the light source 733.

[0062] Start the second hydraulic cylinder 716. The second hydraulic cylinder 716 drives the annular track 711 to move downward, so that the driving component 72 and the visual detection component 73 approach the battery electrode plate 6. Through the cooperation of the light source 733 and the CCD camera 732, the surface of the continuously advancing battery electrode plate 6 is photographed, achieving the purpose of detecting cracks on the surface of the battery electrode plate 6. Through the photographed image information, the external system can identify whether there are cracks, and then can judge the newness and oldness of the battery electrode plate 6.

[0063] Further, the battery core separation device further includes an attitude adjustment mechanism 3, a tension adjustment mechanism 4, a tension detection mechanism 5, and a clamping and conveying mechanism 8. The attitude adjustment mechanism 3 includes a first hydraulic motor 31, a fixing plate 32, a connecting platform 33, a transmission gear 34, a driving gear 35, a movable plate 36, and a rotating gear 37. A connecting bottom plate 12 is provided on the side of the anti-breaking mechanism 7 away from the bottom plate 1. The movable plate 36 is provided on the lower side of the connecting bottom plate 12. The tension detection mechanism 5 is fixedly installed on the movable plate 36. The side of the tension detection mechanism 5 away from the movable plate 36 is fixedly connected to the connecting platform 33. The side of the connecting platform 33 away from the movable plate 36 is fixedly connected to the rotating gear 37. The outer side of the rotating gear 37 is engaged with the transmission gear 34, and the outer side of the transmission gear 34 is engaged with the driving gear 35. The transmission gear 34 and the driving gear 35 are provided on the side away from the movable plate 36 with a fixing plate 32. The fixing plate 32 is fixedly connected to the first hydraulic motor 31. The output end of the first hydraulic motor 31 is fixedly connected to the driving gear 35. The inner side of the transmission gear 34 is rotatably connected to a connecting shaft, and the connecting shaft is fixedly connected to the fixing plate 32.

[0064] Start the first hydraulic motor 31. The first hydraulic motor 31 drives the driving gear 35 to rotate. The driving gear 35 drives the transmission gear 34 through meshing. The transmission gear 34 drives the rotating gear 37 through meshing, and then drives the movable plate 36 and the mechanisms on the movable plate 36 to rotate synchronously, making the fold angle of the battery electrode plate 6 larger. The older the battery electrode plate 6 is, the larger the fold angle of the battery electrode plate 6 is, further avoiding the possibility of the battery electrode plate 6 breaking.

[0065] Further, the tension adjusting mechanism 4 includes a collecting chamber 41, an adjusting roller 42, a cleaning roller 43, a driving member 44, a second hydraulic motor 45, and a first hydraulic cylinder 46. The connecting bottom plate 12 is fixedly connected to the first hydraulic cylinder 46 through a rectangular block. The output end of the first hydraulic cylinder 46 is fixedly connected to the second hydraulic motor 45. The output end of the second hydraulic motor 45 is fixedly connected to the adjusting roller 42 and the cleaning roller 43. One ends of the adjusting roller 42 and the cleaning roller 43 are connected to the driving member 44 through bearings. The driving member 44 is fixed to the second hydraulic motor 45. A slot corresponding to the driving member 44 is formed in the connecting bottom plate 12.

[0066] Based on the newness of the battery electrode sheet 6, its running speed is adjusted. When the battery electrode sheet 6 is relatively new, the running speed is faster; when the battery electrode sheet 6 is relatively old, the running speed is slower. At the same time, its tension is adjusted. The tension sensor 52 can detect the tension when the battery electrode sheet 6 is separated. By controlling the extension and retraction of the first hydraulic cylinder 46, the tension can be controlled to become smaller and larger. When the battery electrode sheet 6 is relatively new, the tension is larger; when the battery electrode sheet 6 is relatively old, the tension is smaller. At the same time, while the second hydraulic motor 45 drives the adjusting roller 42 and the cleaning roller 43 to rotate, since the cleaning roller 43 is provided with evenly distributed bristles, the adjusting roller 42 can be cleaned, and the negative residue can be cleaned and collected into the collecting chamber 41.

[0067] Further, the tension detecting mechanism 5 includes a guiding roller 51 and a tension sensor 52. The guiding roller 51 is fixedly installed on the movable plate 36, and the tension sensor 52 is arranged at one end of the guiding roller 51 away from the movable plate 36.

[0068] The clamping and conveying mechanism 8 includes a regulating assembly 81 and a vacuum adsorption roller 82. A moving assembly 13 is fixedly connected to one side of the connecting bottom plate 12 close to the anti-breaking mechanism 7. The output end of the moving assembly 13 is fixedly connected to the regulating assembly 81. The regulating assembly 81 includes a guide rail 811, a third motor 812, a second bidirectional lead screw 813, a mounting seat 814, a second slider 815, and a bearing seat 816. The output end of the moving assembly 13 is fixedly connected to two groups of guide rails 811 through a straight plate. The inner side of the guide rail 811 is fixedly connected to the third motor 812. The output end of the third motor 812 is fixedly connected to the second bidirectional lead screw 813. The second bidirectional lead screw 813 is connected to the mounting seat 814 through a bearing. The mounting seat 814 is fixed to the guide rail 811. Two groups of second sliders 815 are threadedly connected to the outer side of the second bidirectional lead screw 813. The second sliders 815 slide on the guide rail 811. One side of the second slider 815 is fixedly connected to the bearing seat 816. The inner side of the bearing seat 816 is connected to the vacuum adsorption roller 82 through a bearing.

[0069] Start motor three 812, and motor three 812 drives the bidirectional lead screw two 813 to rotate. During the rotation of the bidirectional lead screw two 813, the vacuum adsorption rollers 82 are driven to separate from each other through the slider two 815 and the bearing seat 816, so that the two groups of vacuum adsorption rollers 82 move to the outside of the first layer where the core is disconnected. Then, control motor three 812 to reverse, and the two groups of vacuum adsorption rollers 82 clamp and hold the first layer where the core is disconnected;

[0070] Further, the battery core separation device further includes a flipping and peeling mechanism 2, a negative electrode collection mechanism 9, a separation mechanism 10, and a core film peeling assembly 11. The flipping and peeling mechanism 2, the negative electrode collection mechanism 9, and the separation mechanism 10 are fixedly connected to the bottom plate 1. The separation mechanism 10 includes a guide roller group 1001, a cutting die assembly 1002, a film suction assembly 1003, and a peeling part 1004. Two groups of guide roller groups 1001 are rotatably connected to the movable plate 36. The cutting die assembly 1002 is arranged outside the guide roller group 1001 and is fixed to the movable plate 36. The film suction assemblies 1003 are arranged on both sides of the lower part of the guide roller group 1001 and are fixed to the movable plate 36. The peeling part 1004 is fixedly installed on the upper side of the negative electrode collection mechanism 9;

[0071] The flipping and peeling mechanism 2 lifts the core to have enough flipping space. The two groups of vacuum adsorption rollers 82 hold one end of the battery electrode plate 6 and continuously pull it forward. Since the negative electrode plate 63 is relatively short, it is peeled off by the peeling part 1004 and automatically falls into the negative electrode collection mechanism 9. The two groups of vacuum adsorption rollers 82 pull the positive electrode plate 61 and the separator 62 to the initial position;

[0072] The movable plate 36 is also fixedly connected with two groups of core film peeling assemblies 11, and the core film peeling assemblies 11 correspond to the film suction assemblies 1003.

[0073] The end of the separator 62 is blown by the blowing component to the cutting die assembly 1002. The cutting die assembly 1002 cuts off the redundant part at the end. Then, the positive electrode plate 61 and the separator 62 are guided by the guide roller group 1001 to move to the film suction assembly 1003. Control the film suction assembly 1003 to start and move closer to the separator 62 to adsorb it, and then rotate, so as to separate the two layers of the separator 62 from the positive electrode plate 61. The separated separator 62 is clamped by an external clamping jaw. Since the external clamping jaw sleeved the separator 62 on the optical axis of the core film peeling assembly 11, the core film peeling assembly 11 rotates, and then continuously winds the separator 62 around the optical axis of the core film peeling assembly 11, so as to realize the separation and recovery of the positive electrode plate 61, the separator 62, and the negative electrode plate 63;

[0074] Further, a peeling assembly corresponding to the flipping and peeling mechanism 2 is fixedly connected to the bottom plate 1, and a blowing component corresponding to the battery electrode plate 6 is fixedly connected to the connecting bottom plate 12.

[0075] The battery core to be separated is placed at the clamping part of the flipping and peeling mechanism 2 for clamping. The first layer of the core that has been disconnected is lifted by the peeling component, and then the moving component 13 is started. The moving component 13 drives the clamping and conveying mechanism 8 to move to the loading position.

[0076] Specific usage method and function of this embodiment:

[0077] During use, first, the battery core to be separated is placed at the clamping part of the flipping and peeling mechanism 2 for clamping. The first layer of the core that has been disconnected is lifted by the peeling component, and then the moving component 13 is started. The moving component 13 drives the clamping and conveying mechanism 8 to move to the loading position;

[0078] The external system controls the start of the third motor 812. The third motor 812 drives the two-way lead screw 813 to rotate. During the rotation of the two-way lead screw 813, the vacuum adsorption rollers 82 are driven to separate from each other through the second slider 815 and the bearing seat 816, so that the two groups of vacuum adsorption rollers 82 move to the outside of the first layer of the disconnected core. Then, the third motor 812 is controlled to reverse, and the two groups of vacuum adsorption rollers 82 clamp and hold the first layer of the disconnected core;

[0079] The flipping and peeling mechanism 2 lifts the core to have enough flipping space. The two groups of vacuum adsorption rollers 82 clamp one end of the battery electrode sheet 6 and continuously pull it forward. Since the negative electrode sheet 63 is relatively short, it is peeled off by the peeling part 1004 and automatically falls into the negative electrode collection mechanism 9. The two groups of vacuum adsorption rollers 82 pull the positive electrode sheet 61 and the separator 62 to the initial position;

[0080] At the same time, a drum film collecting component is arranged on one side of the blowing component. When the drum film collecting component detects that there is material in place, it starts the inner drum to press down and rotate. At this time, the two groups of vacuum adsorption rollers 82 are separated from each other. The end of the separator 62 is blown by the blowing component to the die cutting component 1002. The die cutting component 1002 cuts off the redundant part at the end. Then, the positive electrode sheet 61 and the separator 62 move to the film suction component 1003 through the guiding roller group 1001. The film suction component 1003 is controlled to start and approach the separator 62 to adsorb it, and then rotate, so as to separate the two layers of the separator 62 from the positive electrode sheet 61. The separated separator 62 is clamped by the external clamping jaw. Since the external clamping jaw sleeved the separator 62 on the optical axis of the film unwinding component 11, the film unwinding component 11 rotates, and then continuously winds the separator 62 around the optical axis of the film unwinding component 11, so as to realize the separation and recovery of the positive electrode sheet 61, the separator 62, and the negative electrode sheet 63;

[0081] While performing the separation operation, the second hydraulic cylinder 716 is activated. The second hydraulic cylinder 716 drives the annular track 711 to move downward, causing the driving assembly 72 and the visual inspection assembly 73 to approach the battery electrode plate 6. Through the cooperation of the light source 733 and the CCD camera 732, images of the surface of the continuously advancing battery electrode plate 6 are taken, achieving the purpose of detecting cracks on the surface of the battery electrode plate 6. Through the captured image information, the external system can identify whether there are cracks, and thus can judge the newness and oldness of the battery electrode plate 6;

[0082] When it is recognized that there are many cracks and the battery electrode plate 6 is relatively old, the fixed negative pressure chamber 721 and the movable negative pressure chamber 722 are moved into contact with the battery electrode plate 6. Since the air duct 724 is connected to an external negative pressure mechanism, the fixed negative pressure chamber 721 is formed into a negative pressure state. Through the conduction of the guide pipe 723, the inside of the movable negative pressure chamber 722 is also formed into a negative pressure state. Since the contact surfaces of the fixed negative pressure chamber 721 and the movable negative pressure chamber 722 with the battery electrode plate 6 are both provided with uniformly distributed through holes, the fixed negative pressure chamber 721 and the movable negative pressure chamber 722 adsorb the battery electrode plate 6. At the same time, the first motor 714 is activated. The first motor 714 drives the sprocket 713 to rotate, and then the sprocket 713 meshes to drive the chain 712 to perform circular motion. The chain 712 drives the driving assembly 72, the visual inspection assembly 73, and the connecting assembly 74 to perform circular motion, so as to move along with the battery electrode plate 6. Thus, when separating the relatively old battery electrode plate 6, it provides auxiliary driving during transportation to prevent it from breaking due to excessive tension;

[0083] At the same time, for the unrolled battery electrode plate 6, the second motor 7251 is controlled to start. The second motor 7251 drives the bidirectional lead screw 7253 to rotate. While the bidirectional lead screw 7253 is rotating, it drives the slider 7254 to slide outwards, thereby driving the movable negative pressure chamber 722 to move outwards, so as to perform a stretching operation on the battery electrode plate 6 and ensure the normal operation of the separation operation;

[0084] When the two vacuum adsorption rollers 82 pull the battery electrode plate 6 into place, the vacuum adsorption rollers 82 can be controlled to move to the suspended position of the battery electrode plate 6. The vacuum adsorption rollers 82 rotate through an external driving device to provide auxiliary support and transportation for the battery electrode plate 6, reducing the possibility of the battery electrode plate 6 breaking;

[0085] Meanwhile, the external system adjusts its operating speed according to the degree of newness of the battery electrode sheet 6. When the battery electrode sheet 6 is relatively new, the operating speed is relatively fast; when the battery electrode sheet 6 is relatively old, the operating speed is relatively slow. At the same time, it adjusts the tension. The tension sensor 52 can detect the tension when the battery electrode sheet 6 is separated. By controlling the extension and retraction of the first hydraulic cylinder 46, the tension can be controlled to become smaller and larger, so that when the battery electrode sheet 6 is relatively new, the tension is relatively large; when the battery electrode sheet 6 is relatively old, the tension is relatively small. Meanwhile, while the second hydraulic motor 45 drives the adjusting roller 42 and the cleaning roller 43 to rotate, since the cleaning roller 43 is provided with uniformly distributed bristles, the adjusting roller 42 can be cleaned, so that the negative residue can be cleaned and collected into the collection chamber 41;

[0086] When the battery electrode sheet 6 is relatively old, the external system starts the first hydraulic motor 31. The first hydraulic motor 31 drives the driving gear 35 to rotate. The driving gear 35 meshes with and drives the transmission gear 34, and the transmission gear 34 meshes with and drives the rotating gear 37, thereby driving the movable plate 36 and the mechanism on the movable plate 36 to rotate synchronously, so that the folding angle of the battery electrode sheet 6 becomes larger. The older the battery electrode sheet 6 is, the larger the folding angle of the battery electrode sheet 6 is, further avoiding the possibility of the battery electrode sheet 6 breaking;

[0087] Meanwhile, according to the requirements, the adjustment of the separation and collection position can be freely adjusted to meet different needs;

[0088] When the battery electrode sheet 6 breaks, the separation operation stops at this time. The fixed negative pressure chamber 721 and the movable negative pressure chamber 722 are controlled to adsorb the battery electrode sheet 6 with a relatively small adsorption force first and move forward at the same time, thereby driving the battery electrode sheet 6 to flatten and straighten. When the CCD camera 732 moves to the break of the battery electrode sheet 6, the adsorption force is increased, thereby pulling the battery electrode sheet 6 to be docked with the two groups of vacuum adsorption rollers 82, and then realizing the connection operation of the broken battery electrode sheet 6.

[0089] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
