Description

Technical Field

[0001] The present disclosure relates to the technical field of battery recycling, and in particular to a battery core kneading mechanism and a core kneading device. Background Art

[0002] In order to achieve effective resource recycling and reuse, the battery core disassembly process is particularly important, but the key technologies in various links of battery core recycling at home and abroad are not mature enough. Most battery recycling companies still use manual disassembly or traditional crushing and screening processes, which not only causes a large waste of resources, but also harms humans and the environment. Due to reasons such as battery core oxidation, the positive / negative electrode sheets and diaphragms are relatively sticky, which makes it difficult to disassemble them in a refined manner.

[0003] In addition, battery cores are usually formed in pairs and fixed by Mylar film. Currently, there is no recycling device that can separate paired battery cores into single cores. Therefore, it is necessary to provide a device that can compress the battery cores and disassemble the paired battery cores. Utility Model Content

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a battery core kneading mechanism and a battery core kneading device that can realize the kneading of the battery core and can split a pair of battery cores into a single core.

[0006] A battery core kneading mechanism, comprising:

[0007] A clamping assembly, comprising a clamping drive and two clamping air claws, wherein the two clamping air claws are respectively fixedly connected to the horizontal driving shafts on both sides of the clamping drive to jointly form a winding core processing groove, and each of the clamping air claws is provided with a notch communicating with the winding core processing groove;

[0008] The kneading and cutting mechanism includes two rotating driving members and two oppositely arranged kneading and cutting components, each of the rotating driving members is installed on the corresponding clamping air claws, each of the kneading and cutting components is rotatably arranged in the corresponding notch, and each of the kneading driving components is fixedly connected to the power output end of the corresponding rotating driving member so that the kneading and cutting components swing to knead the battery roll core.

[0009] In one embodiment, each of the kneading and cutting components further includes a kneading component and a cutting component connected to each other, wherein the cutting component is arranged below the kneading component, and the cutting component is used to cut the Mylar film of the battery core in the core processing groove; the kneading component is used to clamp the battery core in the core processing groove.

[0010] In one of the embodiments, each of the kneading components includes a kneading driving member and two kneading claws. The kneading driving member is rotatably arranged in the corresponding slot and fixedly connected to the power output end of the rotating driving member. The two kneading claws are respectively fixedly connected to the two rotating driving ends of the kneading driving member, so that the kneading driving member drives the two kneading claws to rotate toward or away from each other in the winding core processing groove.

[0011] In one embodiment, the kneading driving member is provided with two avoidance grooves, and corresponding rotating members are respectively arranged in the two avoidance grooves. The two kneading clamps are respectively fixedly connected to the two rotating members, and the two rotating members are respectively fixedly connected to the two rotating driving ends of the kneading driving member.

[0012] In one embodiment, each of the kneading jaws comprises a rotating portion and a kneading clamping portion, each of the kneading clamping portion is connected to the corresponding rotating portion, and each of the rotating portion is fixedly connected to the corresponding rotating member.

[0013] In one embodiment, each of the cutting components includes a cutting drive, a compression rod and a cutting knife, wherein the cutting knife is connected to one end of the compression rod, and the other end of the compression rod is fixedly connected to the power output end of the cutting drive.

[0014] A core kneading device comprises a workbench, a cantilever crane and the battery core kneading mechanism described in any embodiment, the cantilever crane comprises a support column and a rotating assembly, the rotating assembly is rotatably connected to the support column, the rotating assembly is provided with a connecting portion at one end away from the support column, the connecting portion is connected to the battery core kneading mechanism, and the battery core kneading mechanism is located directly above the workbench.

[0015] In one embodiment, the rotating assembly includes a rotating column, a rotating joint and a mechanical arm connected in sequence, the connecting portion is provided on the mechanical arm, the rotating column is rotatably connected to the supporting column, and the mechanical arm is connected to the rotating joint.

[0016] In one of the embodiments, the core kneading device further comprises an image collector, which is disposed at a position where the support column faces the workbench, and a collection end of the image collector is located on the same horizontal plane as the workbench.

[0017] In one of the embodiments, the core kneading device further includes a controller, which is electrically connected to the battery core kneading mechanism, which is also electrically connected to the control end of the rotating assembly, and which is also electrically connected to the image collector.

[0018] Compared with the prior art, the present invention has the following advantages, including but not limited to:

[0019] 1. The above-mentioned battery roll core kneading mechanism drives the clamping claws on both sides to move through the clamping driving member, and the kneading and cutting components on both sides move with the clamping claws. At the same time, the kneading components of each kneading and cutting component clamp the battery roll core. When the battery roll core is fixed in pairs, the kneading components clamp the paired battery roll cores, and also cut the Mylar film of the paired battery roll cores through the cutting components to obtain a single battery roll core, which is convenient for the subsequent rotary driving member to drive the kneading and cutting components to rotate to knead the battery roll core. Compared with manual disassembly or traditional crushing and screening processes, the above-mentioned battery roll core kneading mechanism is easier in the subsequent refined disassembly process.

[0020] 2. The above-mentioned core kneading device can first scan the battery core on the workbench through the image acquisition device, that is, a single battery core or a double battery core. When the battery core is a single battery core, the two rotating driving parts respectively drive the corresponding kneading and cutting components to rotate, and directly knead the battery core; when the battery core is a double battery core, the Mylar film is first cut by the cutting component of the battery core kneading mechanism, and then the kneading and cutting components are driven to rotate by the rotating driving part to perform the kneading operation of the single battery core, so that the battery core can be disassembled.

[0021] 3. Since the battery core is easily oxidized, causing the positive / negative plates to stick together, they are prone to breakage during the fine disassembly process. After the core kneading device kneads the battery core, the stability and disassembly efficiency of the back-end fine disassembly equipment are improved. In particular, when the battery core is a liquid-injected core, the liquid-injected core can be kneaded by the core kneading device. After kneading, the contact area between the battery core and the air is increased, thereby accelerating the volatilization of the electrolyte and reducing the back-end drying time.

[0031] In order to facilitate the understanding of the present disclosure, the present disclosure will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present disclosure are given in the drawings. However, the present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present disclosure more thoroughly and comprehensively understood.

[0032] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0033] like Figure 1 As shown, a battery core rolling mechanism 10 of an embodiment includes a clamping assembly 100 and a rolling and cutting mechanism. The clamping assembly 100 includes a clamping drive 110 and two clamping air claws 120. The two clamping air claws 120 are respectively fixedly connected to the horizontal driving shafts on both sides of the clamping drive 110 to jointly form a core processing groove. The clamping drive 110 drives the two clamping air claws 120 to move horizontally toward or away from the clamping drive 110. Each clamping air claw 120 is provided with a notch 1 connected to the core processing groove. 21; The kneading and cutting mechanism includes two rotating driving members (not shown) and two oppositely arranged kneading and cutting components 200, each rotating driving member is installed on the corresponding clamping claw 120, each kneading and cutting component 200 is rotatably arranged in the corresponding notch 121, and each kneading and cutting component 200 is fixedly connected to the power output end of the corresponding rotating driving member, so that the rotating driving member drives the kneading and cutting component 200 to rotate back and forth between clockwise and counterclockwise directions along the rotating axis of the rotating driving member, which makes the kneading operation easier.

[0034] like Figure 1 As shown, in one embodiment, each kneading and cutting assembly 200 includes a kneading component 210 and a cutting component 220 connected to each other. The cutting component 220 is arranged below the kneading component 210, and the cutting component 220 is used to cut the Mylar film of the battery core 11 in the core processing groove (such as Figure 6 As shown), the cutting component 220 cuts the Mylar film 11a of the dual battery core; the kneading component 210 is used to clamp the battery core in the core processing groove.

[0035] It can be understood that the battery roll core 11 can be a single battery roll core or a dual battery roll core. For a single battery roll core, there is no need to cut the Mylar film, only kneading operation is required. For a dual battery roll core, not only is it necessary to cut the Mylar film, but also kneading operation is required. It should be noted that the dual battery roll core includes two roll core monomers and a Mylar film connecting the two roll core monomers respectively. For a dual battery roll core, after cutting the Mylar film, the kneading component 210 clamps the battery roll core 11 after the Mylar film 11a is cut in the roll core processing groove, that is, the kneading component 210 clamps each roll core monomer in turn, and then drives the corresponding kneading and cutting assembly 200 to rotate through each rotating drive member to knead the roll core monomer.

[0036] In this embodiment, the battery core kneading mechanism 10 drives the clamping claws 120 on both sides to move through the clamping driving member 110, and the kneading and cutting components 200 on both sides move with the clamping claws 120. At the same time, the corresponding kneading components 210 on both sides clamp the battery core 11 respectively. When the battery core is fixed in pairs, the kneading component 210 clamps the paired battery cores, and the Mylar film of the paired battery core is cut by the cutting component 220 to obtain a single battery core 11, which is convenient for the subsequent rotation of the kneading and cutting component 200 to knead the core monomer. Compared with manual disassembly or traditional crushing and screening process, the above-mentioned battery core kneading mechanism 10 is easier in the subsequent refined disassembly process.

[0037] In this embodiment, the kneading component 210 clamps the battery core 11 in the core processing groove. Specifically, the kneading component 210 clamps the battery core 11 in the core processing groove, and drives the kneading and cutting assembly 200 to rotate through the rotating driving member to knead the battery core 11. Figure 2 As shown, each kneading component 210 includes a kneading driving member 211 and two kneading jaws 212. The kneading driving member 211 is rotatably arranged in the corresponding slot 121 and is fixedly connected to the power output end of the rotating driving member. The two kneading jaws 212 are respectively fixedly connected to the two rotating driving ends of the kneading driving member 211, so that the kneading driving member 211 drives the two kneading jaws 212 to rotate toward or away from each other in the winding core processing groove.

[0038] Furthermore, if Figure 2 As shown, each cutting component 220 includes a cutting drive component 221, a compression rod 222 and a cutting knife 223. The cutting knife 223 is connected to one end of the compression rod 222, that is, the cutting knife 223 is screwed to the compression rod 222 by screws, and the other end of the compression rod 222 is fixedly connected to the power output end of the cutting drive component 221. The compression rod 222 and the cutting knife 223 are both located below the kneading component 210. The rotation center of the kneading clamp 212 is taken as the reference point; when the cutting drive 221 drives the compression rod 222 to extend to the maximum length, the length of the end of the cutting knife 223 away from the compression rod 222 and the reference point in the horizontal direction is greater than the length of the end of the kneading clamp 212 away from the reference point and the reference point in the horizontal direction, so as to avoid the kneading parts 210 of the two kneading and cutting assemblies 200 interfering with each other when the cutting parts 220 cut the Mylar film on the battery roll core; when the cutting drive 221 drives the compression rod 222 to retract to the minimum length, the length of the end of the cutting knife 223 away from the compression rod 222 and the reference point in the horizontal direction is less than the length of the end of the kneading clamp 212 away from the reference point and the reference point in the horizontal direction, so as to avoid the cutting parts 220 of the two kneading and cutting assemblies 200 interfering with each other when the kneading parts 210 clamp the battery roll core.

[0039] In this embodiment, if Figure 2 As shown, the two kneading jaws 212 corresponding to each side are respectively fixedly connected to the two rotating drive ends of the corresponding kneading driving member 211, and the two kneading jaws 212 are arranged at intervals in the vertical direction to better knead the battery core 11, so that the viscosity between the pole piece and the diaphragm is reduced, which is convenient for subsequent fine disassembly. When the kneading component 210 is not working, the kneading component 210 is in an open state, that is, the top kneading jaw 212 is rotated back to an outward eight shape relative to the bottom kneading jaw 212. When the kneading component 210 clamps the single battery roll core 11 located in the roll core processing groove, the clamping driving member 110 drives the two clamping air claws 120 to move toward the clamping driving member 110, and at the same time, the kneading driving member 211 drives the corresponding two kneading jaws 212 to move until the kneading component 210 is in a closed state, that is, the top kneading jaw 212 rotates toward the bottom kneading jaw 212 to close, or the bottom kneading jaw 212 rotates toward the top kneading jaw 212 to close. Figure 4 As shown, the two kneading components 210 respectively clamp the battery winding core ( Figure 4 At the same time, the two rotating driving members drive the corresponding kneading and cutting components 200 to reciprocate between clockwise and counterclockwise directions along the driving axis of the rotating driving member, that is, to swing up and down relative to the vertical direction to knead the battery roll core 11.

[0040] To facilitate relevant technical personnel to understand the solution, the implementation process of the solution will be described in detail below:

[0041] like Figure 1 , Figure 4 and Figure 6 As shown, first, before kneading the battery core 11, the controller 600 collects the status information of the battery core kneading mechanism 10, checks whether the two clamping air claws 120 are in the standby state, checks whether each kneading jaw 212 is in the open state, that is, the top kneading jaw 212 is rotated back to the outside eight shape relative to the bottom kneading jaw 212, and checks whether the compression rod 222 in each cutting component 220 is retracted. When it is determined that the two clamping air claws 120 are in the standby state, the corresponding two kneading jaws 212 are in the open state, and the compression rod 222 on each side is retracted, the squeezing operation of the battery core 11 can be performed.

[0042] Combination Figure 1 , Figure 2 , Figure 4 and Figure 6As shown, secondly, when the incoming material is a single battery roll core, the kneading and cutting components 200 on both sides follow the clamping claws 120 to move, and at the same time, the corresponding kneading driving member 211 drives the corresponding two kneading jaws 212 to move to clamp the battery roll core 11, that is, each kneading jaw 212 is against the outer wall of the battery roll core 11 to close, and the controller 600 controls the swing of the mechanical arm, and the mechanical arm drives the battery roll core kneading mechanism 10 to rise a predetermined distance, and the two rotating driving members drive the corresponding kneading and cutting components 200 to reciprocate between clockwise and counterclockwise directions along the driving axis of the corresponding rotating driving member to perform Kneading operation: When the incoming material is a double battery roll core, the kneading claws 212 adjacent to the compression rods 222 on both sides clamp the upper core monomer of the battery roll core 11 (the effect diagram is not shown), and then the cutting drive members 221 on both sides drive the corresponding compression rods 222 to extend, so that the cutting knife 223 extends synchronously and cuts the Mylar film 11a, so that the core monomer of the battery roll core 11 is separated, and then the cutting drive member 221 drives the corresponding compression rod 222 to retract, and the compression rod 222 drives the cutting knife 223 to stop cutting to make room for the kneading operation of each core monomer, and then the next step of kneading operation is carried out on the core monomer.

[0043] Again, when kneading the battery core 11 (which can be a single battery core or a separated core monomer), the clamping drive 110 drives the clamping claws 120 on both sides to move inward, that is, to move in the horizontal direction close to the clamping drive 110, and at the same time, the two rotating drives drive the corresponding kneading and cutting components 200 to swing upward together to squeeze the battery core 11, so that the battery core 11 is arched like a "∩" shape, and then the clamping drive 110 drives the clamping claws 120 on both sides to move outward and then inward, and at the same time, the two rotating drives drive the corresponding kneading and cutting components 200 to swing downward together to squeeze the battery core 11 again, so that the battery is concave like a "∪" shape, and this process is repeated 3-5 times, so that the shape of the battery core 11 alternates between the arch shape and the concave shape, and at this time, the two corresponding kneading jaws 212 on both sides always clamp the battery core 11, and the two kneading jaws 212 are stationary relative to the corresponding kneading drive 211. Compared with the structure before kneading, the structure of the battery roll core 11 is softer at this time, so as to facilitate subsequent disassembly.

[0044] Finally, after the battery roll core 11 is kneaded back and forth into an arched (“∩”) shape or a concave (“∪”) shape through the squeezing operation, the two kneading and cutting components 200 will perform the next kneading operation on the battery roll core 11 . During the kneading of the battery core 11, the two clamping air claws 120 always perform a reciprocating motion first outward and then inward along the horizontal driving axis of the corresponding clamping drive member 110, and each kneading and cutting component 200 follows the corresponding clamping air claws 120 to reciprocate to repeatedly stretch the battery core 11. The two kneading and cutting components 200 are respectively the first kneading and cutting component and the second kneading and cutting component; the first kneading and cutting component moves relative to the second kneading and cutting component, and the second kneading and cutting component is in a stationary state; or, the second kneading and cutting component moves relative to the first kneading and cutting component, and the first kneading and cutting component is in a stationary state; or the first kneading and cutting component and the second kneading and cutting component move in opposite directions respectively, for example, the first kneading and cutting component swings upward, and the second kneading and cutting component swings downward; for another example, the first kneading and cutting component swings downward, and the second kneading and cutting component swings upward. This operation makes the battery core 11 appear in a wavy line ("~") shape. The entire kneading process is repeated 3-5 times, which greatly reduces the adhesion between the electrode and the diaphragm, making it easier to disassemble in detail later.

[0045] The battery core kneading mechanism 10 is suitable for kneading treatment of liquid-filled battery cores and non-liquid-filled battery cores before fine disassembly, in order to obtain purer positive / negative electrode sheets during the rear-end battery core disassembly process, and also to improve the stability and efficiency of the disassembly equipment.

[0046] like Figures 2 to 4 As shown, in one of the embodiments, the kneading driving member 211 is provided with two avoidance grooves 2111, and corresponding rotating members 2112 are respectively provided in the two avoidance grooves 2111, and the two kneading jaws 212 are respectively fixedly connected to the two rotating members 2112, and the two rotating members 2112 are respectively fixedly connected to the two rotating driving ends of the kneading driving member 211, so that when at least one kneading driving member 211 drives the corresponding at least one kneading jaw 212 to rotate, the driven kneading jaw 212 rotates by cooperating with the rotation of the corresponding rotating member 2112.

[0047] like Figure 5As shown, in one embodiment, each kneading clamp 212 includes a rotating portion 2121 and a kneading clamp 2122, each kneading clamp 2122 is connected to the corresponding rotating portion 2121, and further, the kneading clamp 2122 is screwed to the connecting rotating portion 2121 through a bolt 2123 passing through a fixing bolt hole 2124, and each rotating portion 2121 is fixedly connected to the corresponding rotating member 2112. In this embodiment, the kneading clamp 2122 is a silicone pad, and when the battery core kneading mechanism 10 kneads the battery core 11, the silicone pad plays a buffering and close-fitting role on the battery core 11, thereby preventing the battery core kneading mechanism 10 from sliding when kneading the battery core 11.

[0048] Furthermore, if Figure 5 As shown, the rotating part 2121 is provided with a through hole 21211, and the rotating member 2112 is inserted into the through hole 21211 and abuts against the inner wall of the through hole 21211, so that when the rotating member 2112 rotates, the rotating part 2121 swings in coordination with the rotation of the rotating member 2112, and the kneading clamp 2122 also swings with the rotating part 2121.

[0049] like Figure 6 As shown, the present disclosure also provides a core kneading device 20, including a workbench 300, a cantilever crane 400 and a battery core kneading mechanism 10 of any embodiment, the cantilever crane 400 includes a support column 410 and a rotating assembly 420, the rotating assembly 420 is rotatably connected to the support column 410, specifically, a rotating shaft connected to the inside of the support column 410, and a connecting portion 4201 is provided at one end of the rotating assembly 420 away from the support column 410, and the connecting portion 4201 is connected to the battery core kneading mechanism 10, and the battery core kneading mechanism 10 is located directly above the workbench 300, so that when kneading the battery core 11, it is convenient to rotate the rotating assembly 420 to make the battery core kneading mechanism The battery core kneading mechanism 10 is close to the battery core 11, and the kneading claws 212 in the battery core kneading mechanism 10 cooperate with the clamping air claws 120 to clamp the battery core 11 located on the workbench 300. If the battery core 11 is a pair of battery cores, the Mylar film 11a of the pair of battery cores can be cut by the cutting component 220 to divide the battery core into single core monomers, and then each core monomer is clamped by the kneading component 210, and then the kneading and cutting component 200 is driven to rotate by the rotating drive member to knead the core monomer; if the battery core 11 is a single battery core, it can be directly clamped by the kneading component 210, and the kneading and cutting component 200 is driven to rotate by the rotating drive member to perform the kneading operation.

[0050] Furthermore, the connection part 4201 has a gravity joint 42011, and the battery core kneading mechanism 10 is connected to the connection part 4201 via the gravity joint 42011, so that when the rotating component 420 rotates, the bottom of the battery core kneading mechanism 10 is always facing the workbench 300.

[0051] like Figure 7 As shown, in one embodiment, the rotating assembly 420 includes a rotating column 421, a rotating joint 422 and a robotic arm 423 connected in sequence, the connecting portion 4201 is arranged at one end of the robotic arm 423 away from the rotating joint 422, the rotating column 421 is rotatably connected to the support column 410, specifically, is connected to the rotating shaft in the support column 410, and the robotic arm 423 is connected to the rotating joint 422 so that the robotic arm 423 rotates up and down along the rotating joint 422. It can be understood that the rotating column 421 can be rotatably arranged in the support column 410, so that the rotating column 421 rotates in the support column 410, that is, it rotates in the A direction or the B direction, and the robotic arm 423 moves clockwise or counterclockwise with the rotating column 421 as a fixed point, that is, it moves in the left and right directions relative to the horizontal direction; the robotic arm 423 is movably connected to the rotating joint 422, so that the rotating joint 422 rotates in the C direction or the D direction, and the robotic arm 423 moves clockwise or counterclockwise with the rotating joint 422 as a fixed point, that is, it swings in the up and down directions relative to the vertical direction, and the battery roll core kneading mechanism 10 also moves up and down with the robotic arm 423.

[0052] Furthermore, if Figure 6 As shown, the workbench 300 includes a support frame 310 and a conveying platform 320. The conveying platform 320 is arranged on the support frame 310, and the battery core kneading mechanism 10 is located directly above the conveying platform 320. It can be understood that the conveying platform 320 is fixed on the support frame 310, and the conveying platform 320 is used to place the battery core 11. Subsequently, by rotating the rotating column 421 and swinging the mechanical arm 423, the battery core kneading mechanism 10 approaches the battery core 11, and the two clamping air claws 120 are driven to move by the clamping driving member 110. At the same time, the two kneading and cutting assemblies 200 follow the corresponding clamping air claws 120 to move, and the corresponding kneading jaws 212 clamp the battery core 11 for subsequent kneading operations.

[0053] like Figure 6 As shown, in one embodiment, the core kneading device 20 also includes an image collector 500, which is arranged at a position where the support column 410 faces the workbench 300, and the collecting end of the image collector 500 is located on the same horizontal plane as the workbench 300, so as to detect the battery core 11 to determine the type of the battery core 11 to be disassembled, determine whether the two cutting components 220 cut the Mylar film 11a of the battery core 11, and also identify the position of the Mylar film 11a in the upper core monomer state clamped into a double battery core.

[0054] It can be understood that when the image collector 500 detects that the battery roll core 11 is a single battery roll core, the image collector 500 first records the category information of the current battery roll core 11, and then, according to the category information of the battery roll core 11, the kneading component 210 clamps the single battery roll core, that is, after each kneading clamp 212 clamps the single battery roll core, each rotating drive member drives the corresponding kneading and cutting assembly 200 to swing and knead; when the image collector 500 detects that the battery roll core 11 is a double battery roll core, the image collector 500 first records the category information of the current battery roll core 11, and then, the kneading clamp adjacent to the cutting component 220 212 clamps the upper core monomer of the double battery core, the image collector 500 records the position of the Mylar film 11a and transmits the relevant information to the controller, the battery core kneading mechanism 10 cuts the Mylar film 11a of the double battery core through two cutting components 220, and after cutting, the two kneading driving members 211 drive the corresponding kneading claws 212 to close to clamp each core monomer, and then the clamping driving member 110 drives the two clamping air claws 120 to move inward, and at the same time, the two rotating driving members respectively drive the corresponding kneading and cutting components 200 to swing up and down to clamp and knead each separated core monomer.

[0055] like Figure 6 As shown, in one embodiment, the core kneading device 20 further includes a controller 600, which is electrically connected to the battery core kneading mechanism 10, that is, the controller 600 is electrically connected to the control end of the clamping drive 110, the control end of the kneading drive 211, the control end of the cutting drive 221, and the control end of the rotating drive, respectively. The controller 600 is also electrically connected to the control end of the rotating assembly 420, that is, the controller 600 is electrically connected to the rotating end of the rotating column 421 adjacent to the support column 410 and the rotating electrical connection end of the rotating joint 422, respectively, and the controller 600 is also electrically connected to the image collector 500. It should be noted that the method in which the controller 600 controls the actions of the clamping drive 110, the kneading drive 211, the cutting drive 221, and the rotating assembly 420 according to the collected data of the image collector 500 belongs to the prior art, and this application only protects their connection relationship and position relationship.

[0056] It can be understood that the controller 600 can control the battery core kneading mechanism 10 to move horizontally or vertically. Furthermore, the controller 600 controls the rotating end of the rotating column 421 adjacent to the support column 410 to rotate the rotating column 421. The rotation of the rotating column 421 causes the connected rotating joint 422 and the mechanical arm 423 to rotate along with the rotating column 421, and the battery core kneading mechanism 10 also moves left and right in a relative horizontal direction along with the rotating column 421; the controller 600 controls the rotating power supply end of the rotating joint 422 to make the mechanical arm 423 move up and down in the vertical direction along the rotating joint 422, so that the battery core kneading mechanism 10 moves up and down with the mechanical arm 423. In addition, the controller 600 can also control the clamping drive 110 to drive the clamping air claw 120 to move horizontally, control the kneading drive 211 to drive the corresponding two kneading claws 212 to close or open along the two driving axes of the kneading drive 211, and control the cutting drive 221 to drive the compression rod 222 to telescope, and the cutting knife 223 follows the telescopic movement of the compression rod 222; the controller 600 can also control the two rotating drives to drive the corresponding kneading and cutting components 200 respectively, so that the kneading and cutting components 200 swing up and down along the driving axis of the rotating drive; the controller 600 can also control the image collector 500. When it is necessary to collect the category of the battery roll core 11, the image collector 500 is controlled by operating the controller 600 to collect the battery roll core 11. The type of the battery core 11 is collected to determine whether the two cutting components 220 cut the Mylar film 11a of the battery core. If the image collector 500 recognizes that the battery core 11 is a double battery core, the kneading claws 212 adjacent to the compression rods 222 on both sides clamp the upper core monomer of the battery core 11. At this time, the controller 600 can record the position of the Mylar film 11a by controlling the image collector 500 to collect. The image collector 500 transmits the position information of the Mylar film 11a to the controller 600. The controller 600 controls the clamping component 100 and the two kneading and cutting components 200 to perform the cutting step according to the relevant information, that is, the Mylar film 11a is cut by the cutting components 220 of the two kneading and cutting components 200.

[0057] Compared with the prior art, the present invention has the following advantages, including but not limited to:

[0058] 1. The battery core kneading mechanism 10 drives the clamping claws 120 on both sides to move through the clamping driving member 110, and the kneading and cutting components 200 on both sides move with the clamping claws 120. At the same time, each kneading component 210 clamps the battery core 11. When the battery core is fixed in pairs, the kneading component 210 clamps the paired battery cores 11, and also cuts the Mylar film of the paired battery cores through the cutting component 220 to obtain a single battery core 11, so that the subsequent rotary driving member drives the kneading and cutting components 200 to rotate to knead the battery core 11. Compared with manual disassembly or traditional crushing and screening processes, the battery core kneading mechanism 10 is easier in the subsequent refined disassembly process.

[0059] 2. The core kneading device 20 described above can first scan the battery core 11 on the workbench 300 through the image collector 500 to determine the type of the battery core 11 to be disassembled, i.e., a single battery core or a double battery core. When the battery core 11 is a single battery core, the two rotating driving members respectively drive the corresponding kneading and cutting components 200 to rotate, and directly knead the battery core 11; when the battery core 11 is a double battery core, the cutting component 220 of the battery core kneading mechanism 10 is used to cut the Mylar film, and then the kneading and cutting components 200 are driven to rotate by the rotating driving member to perform the kneading operation of the single battery core, so that the battery core 11 can be disassembled.

[0060] 3. Since the battery core is easily oxidized and causes the positive / negative electrode sheets to stick together, they are prone to breakage during the fine disassembly process. After the core kneading device 20 kneads the battery core, the stability and disassembly efficiency of the rear-end fine disassembly equipment are improved. In particular, when the battery core 11 is a liquid-injected core, the core kneading device 20 can knead the liquid-injected core. After kneading, the contact area between the battery core 11 and the air is increased, thereby accelerating the volatilization of the electrolyte and reducing the drying time at the rear end.

[0061] It should be noted that the method of determining the type of battery core to be disassembled by scanning, and the method of recording the position of the Mylar film in the state of the upper core monomer clamped into a double battery core and transmitting the relevant information to the controller, are both prior arts. The present disclosure only protects the connection relationship and positional relationship of the various components of the core kneading device.

[0062] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the disclosed patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the disclosed patent shall be subject to the attached claims.
