Description

Technical Field

[0001] This invention relates to the field of cutting machine technology, specifically to an anti-rolling positioning process and equipment for cutting lithium battery electrode sheets. Background Technology

[0002] The lithium battery electrode cutting machine is a core specialized piece of equipment in the lithium battery production process. It is mainly used to precisely cut rolls or sheets of positive and negative electrode sheets into individual electrode sheets that meet the design dimensions. It is a key process equipment to ensure the consistency of lithium battery performance and safety.

[0003] In the industrial production of lithium-ion battery electrodes, the precision of the cutting process directly determines the mechanical safety and electrochemical performance of the subsequent cell assembly. However, during long-term, high-frequency operation, traditional cutting equipment experiences irreversible wear and passivation of the cutting edge due to continuous friction from the high-hardness active material and metal substrate of the electrode. Lacking online real-time maintenance and adjustment mechanisms, the passivated cutting edge no longer generates pure shearing force upon contact with the electrode, but instead accumulates compressive force. According to the principle of stress distribution, when the hardness and sharpness of the cutting edge decrease, the electrode edge undergoes severe plastic deformation before being cut. This excessive material stretching causes microscopic curling at the physical level on the electrode cut surface. More seriously, this compressive force damages the adhesion of the electrode edge coating, causing active material particles to detach and produce sharp metal burrs. These burrs can easily puncture the separator during subsequent winding or stacking processes, inducing internal short circuits in the battery and creating serious safety hazards. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an anti-rolling positioning process and equipment for cutting lithium battery electrodes. This solves the problem that traditional equipment, due to the lack of real-time trimming, causes the cutting edge to become dull, turning the shearing force into an extrusion force and inducing electrode rolling and burrs, thus creating a safety hazard of puncturing the separator and causing an internal short circuit.

[0012] Preferably, the top guide column array is provided in multiple sets, and the bottom guide column array is provided in multiple sets.

[0013] Preferably, both the top bevel cutting blade and the bottom bevel cutting blade are detachable connections for replacement and maintenance.

[0014] A lithium battery electrode cutting anti-rolling positioning process further includes the following processes: Step 1: Preparation stage. Start the equipment through the control panel. The control panel is connected to the conveying mechanism, guiding mechanism, cutting mechanism, positioning mechanism, stabilizing mechanism and picking mechanism. Place the electrode sheet on the conveyor belt of the conveying mechanism. The conveyor belt is connected to the transmission drive device. The transmission drive device receives the signal from the control panel and generates driving force to prepare to transport the electrode sheet along the preset path. Step 2: Conveying stage. The conveying mechanism is started, the transmission drive device is connected to the conveyor belt, and the transmission drive device generates driving force to drive the conveyor belt to move in a circular motion. The conveyor belt carries the electrode and moves it forward along the direction of the transmission frame to the guiding mechanism area. Step 3: Guiding stage. The guiding mechanism works, the side drive rail connects to the movable rigid plate, and the output end of the side drive rail drives the movable rigid plate to move along the guiding rail to the end of the conveying mechanism. The inclined guiding surface on the movable rigid plate contacts the front end of the electrode and guides it to transition to the upper surface of the movable rigid plate. The movable rigid plate is connected to the guiding reciprocating motor, and the output end of the guiding reciprocating motor is connected to the guiding pressure plate. The guiding reciprocating motor drives the guiding pressure plate to press the electrode downward in parallel to form a clamp. The side drive rail then drives the movable rigid plate and the electrode to return to the position of the cutting mechanism. The guiding pressure plate returns to its original position and releases. Step 4: Positioning Stage. The cutting linear motor is fixedly connected to the top of the cutting support frame, generating a downward linear driving force. This causes the top hollow frame to move downwards synchronously. The top hollow frame drives the top guide rails fixed on both sides to move downwards as a whole. The top rotating cylindrical end is fitted onto the inner wall of the top guide rail, causing it to move downwards. The top rotating cylindrical end is rotatably connected to one end of a rigid connecting rod, causing the rigid connecting rod to swing around the top rotating connection point of the rigid support column fixed on the cutting support frame. The swinging motion of the rigid connecting rod transmits the motion to the bottom rotating cylindrical end, which is rotatably connected to the other end. This causes the bottom rotating cylindrical end to move upwards within the inner wall of the bottom guide rail. The upward movement of the bottom rotating cylindrical end lifts the bottom guide rail, causing the bottom hollow frame fixed on both sides to move upwards as a whole. This results in the top hollow frame moving downwards and the bottom hollow frame moving upwards in opposite directions, bringing them closer together. The top beveled cutting blade, fixed to the inner wall of the top hollow frame, moves downwards synchronously. The bottom hollow frame is fixed to the inner wall of the bottom beveled blade, which moves upward synchronously. The blade edge gradually approaches the electrode plate located between the two. Since the bottom surface of the top hard pressure plate is lower than the blade edge of the top beveled blade and the top surface of the bottom hard pressure plate is higher than the blade edge of the bottom beveled blade, the electrode plate is pre-clamped by the top hard pressure plate and the bottom hard pressure plate before the blade contacts it. When the blade contacts the electrode plate, the resultant force of the hollow frame approaching each other is transmitted to the electrode plate through the blade, and then to the pressure plate. The top blade presses the electrode plate downward, pushing the top hard pressure plate to move upward, causing the fixedly connected top guide post to slide upward along the inner wall of the top hollow frame, compressing the top pressure plate spring connected between the top guide post and the inner wall of the top hollow frame, producing elastic clearance. The bottom blade presses the electrode plate upward, pushing the bottom hard pressure plate to move downward, causing the fixedly connected bottom guide post to slide downward along the inner wall of the bottom hollow frame, compressing the bottom pressure plate spring connected between the bottom guide post and the inner wall of the bottom hollow frame, producing elastic clearance. Step 5: Cutting Stage. During the cutting mechanism's operation, the top and bottom beveled blades move relative to each other and perform oblique shearing on the electrode sheet. The cutting edges of the top and bottom beveled blades intersect, forming a shearing pattern similar to scissors. This allows the electrode sheet to be cut sequentially from one side to the other as the two blades gradually come into contact, thus gradually transmitting the shearing force along the cutting line. This effectively reduces the instantaneous impact force and prevents the entire cutting edge from simultaneously squeezing the electrode sheet, thereby reducing the risk of edge curling caused by the material being squeezed and stretched at the edge of the electrode sheet. Simultaneously, the oblique shearing also allows the material deformation generated during the cutting process to be released along the direction of the cutting edge, improving the flatness and stability of the cut surface. When the top and bottom beveled blades complete the staggered shearing, the top beveled blade... The bottom beveled blade continues to move inward and interlaces into the back edge L-shaped plate. Since the back edge L-shaped plate is fixedly connected to the top and bottom beveled blades, it provides back support and limits the movement of these blades during the interlacing process. This improves the overall rigidity of the blades during shearing and reduces minor wobbling under stress. Subsequently, the beveled edges of the top and bottom beveled blades continue to contact the beveled grinding surface of the beveled whetstone. Because the angle of inclination of the grinding surface of the beveled whetstone is the same as that of the beveled edges of the top and bottom beveled blades, sliding friction occurs along the beveled grinding surface during contact. The blade edges exert a holding force on the beveled whetstone during this movement. The grinding contact continues, and because the blade edge and the beveled grinding surface are in inclined contact, a lateral force is generated on the beveled grinding stone along the direction of the long groove when the blade moves forward. This force pushes the beveled grinding stone to move the back edge positioning block along the direction of the long groove and compresses the return spring. The return spring generates elastic compression force, while the first rollers on the upper and lower sides of the back edge positioning block roll against the inner wall of the long groove during movement, thereby guiding the movement direction of the back edge positioning block and reducing sliding friction resistance, allowing the back edge positioning block to move stably along the direction of the long groove. At the same time, the second roller on the side of the beveled grinding stone near the back edge positioning block rolls against the inner wall of the L-shaped back edge plate, providing lateral support to the beveled grinding stone and preventing beveled cutting. During the grinding process, the whetstone tilts, and the third roller at the top of the bevel whetstone rolls against the bottom of the inner wall of the L-shaped back edge plate, thus forming a multi-point rolling support structure with the second roller and the first roller. The bevel whetstone maintains a stable posture during movement and is stably in contact with the beveled edges of the top and bottom beveled blades. During the reciprocating shearing motion of the top and bottom beveled blades, their beveled edges continuously slide along the beveled grinding surface of the bevel whetstone, thereby continuously grinding and adjusting the edges. When the blade leaves the bevel whetstone, the compressed return spring releases its elastic potential energy to push the back edge positioning block to reset the bevel whetstone, so that the bevel whetstone is once again in a position that is compatible with the top and bottom beveled blades. Step Six: Pick-up Stage. After cutting, the pick-up mechanism is activated. The rigid fixing column is fixed on the machine body and connected to the electric pick-up guide rail. The bottom output end of the electric pick-up guide rail is connected to the pick-up head. The bottom of the pick-up head is connected to the suction head. The electric pick-up guide rail drives the pick-up head to move above the electrode. The suction head uses negative pressure to suction the electrode. The electric pick-up guide rail then drives the pick-up head to transfer the electrode to the subsequent station for release.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides an anti-rolling positioning process and equipment for cutting lithium battery electrode sheets, which has the following beneficial effects: 1. The anti-rolling positioning process and equipment for cutting lithium battery electrode sheets utilizes a stabilizing mechanism to continuously grind and trim the oblique cutting edges of the top and bottom oblique cutting blades during continuous operation. This maintains the sharpness of the blade edges and ensures a neat cutting surface for the electrode sheets, reducing edge curling or burrs. It also avoids frequent machine stops for manual blade sharpening, thereby improving the continuous production capacity and cutting stability of the equipment.

[0016] 2. This lithium battery electrode cutting anti-rolling positioning process and equipment utilizes a cutting mechanism to gradually transmit shearing force along the cutting line through oblique shearing. This effectively reduces instantaneous impact force and prevents the entire cutting edge from simultaneously squeezing the electrode, thereby reducing the occurrence of rolling caused by the compression and stretching of the electrode edge material. At the same time, oblique shearing also allows the material deformation generated during the cutting process to be released along the cutting edge direction, improving the flatness and stability of the cut surface. The unidirectional drive of the cutting linear motor enables the synchronous opposite movement of the upper and lower blades, thereby improving cutting efficiency and ensuring blade alignment accuracy, reducing blade offset caused by unilateral force, and improving the electrode cutting quality and equipment operation stability.

[0017] 3. This lithium battery electrode cutting anti-rolling positioning process and equipment utilizes a positioning mechanism to limit and position the electrode during the cutting process. This ensures the electrode is stably clamped between the top and bottom hard pressure plates and remains flat, preventing warping, slippage, or localized lifting during shearing. An elastic clearance space is created when the blade contacts the electrode, ensuring stable holding and accurate positioning throughout the cutting process. This effectively prevents edge rolling, warping, or displacement due to uneven force at the moment of cutting, improving the flatness and cutting accuracy of the electrode cut surface and enhancing the overall processing stability of the lithium battery electrode cutting equipment. Multiple arrays of guide columns and pressure plates provide uniform support and holding along the electrode width, preventing warping, slippage, or edge rolling, improving cutting accuracy and product consistency. It is particularly suitable for cutting wide-width electrodes and can also distribute pressure, avoiding deformation or damage caused by single-point pressure. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-13 A lithium battery electrode cutting anti-rolling positioning device, comprising: Body 1, Electrode 7; Conveying mechanism 2, which is installed on the machine body 1, is used to continuously convey the electrode sheet 7 along a preset path to the cutting position; The cutting mechanism 3 is mounted on the machine body 1. The cutting mechanism 3 is equipped with a top oblique cutting blade 91 and a bottom oblique cutting blade 92, which are used to cut the electrode sheet 7 on both sides obliquely to complete the cutting operation of the electrode sheet 7. The stabilizing mechanism 9 is installed on the top bevel cutting blade 91 and the bottom bevel cutting blade 92 on the cutting mechanism 3, and is used to sharpen the top bevel cutting blade 91 and the bottom bevel cutting blade 92 during the cutting process. Stabilizing agency 9 includes: The back edge L-shaped plate 93, the top bevel cutting blade 91, and the bottom bevel cutting blade 92 are all fixedly connected to the back edge L-shaped plate 93. A long groove 94 is formed on the inner wall of the back edge L-shaped plate 93, and a return spring 95 is installed on the inner wall of the long groove 94. One end of the return spring 95 is fixedly connected to the inner wall of the long groove 94, and the other end is fixedly connected to a back edge positioning block 96. First rollers 98 are provided on both the upper and lower sides of the back edge positioning block 96, and the first rollers 98 abut against the inner wall of the long groove 94. A bevel cutting whetstone 97 is fixedly connected to the back edge positioning block 96. The cutting edges of the top bevel cutting blade 91 and the bottom bevel cutting blade 92 are beveled, and the bevel cutting whetstone 97 has a beveled grinding surface for conforming to the top bevel cutting blade. The cutting blade 91 and the bottom bevel cutting blade 92 have oblique cutting edges. A second roller 99 is provided on the side of the bevel cutting whetstone 97 near the back edge positioning block 96 to abut against the inner wall side of the back edge L-shaped plate 93. A third roller 910 is provided on the top of the bevel cutting whetstone 97 to abut against the bottom of the inner wall of the back edge L-shaped plate 93. During equipment operation, the electrode 7 is continuously conveyed to the cutting mechanism 3 along a preset path by the conveying mechanism 2. During the operation of the cutting mechanism 3, the top bevel cutting blade 91 and the bottom bevel cutting blade 92 move relative to each other and perform oblique shearing on the electrode 7. The cutting edges of the top bevel cutting blade 91 and the bottom bevel cutting blade 92 intersect to form a shearing method similar to scissors, so that the electrode 7 is cut from one side to the other as the two cutting edges gradually come into contact. The cutting process allows the shearing force to be gradually transmitted along the cutting line, effectively reducing the instantaneous impact force and preventing the entire cutting edge from simultaneously squeezing the electrode 7. This reduces the risk of edge curling caused by the material being squeezed and stretched at the edge of the electrode 7. Simultaneously, the oblique shearing allows the material deformation generated during the cutting process to be released along the cutting edge direction, improving the flatness and stability of the cut surface. As the top oblique cutting blade 91 and the bottom oblique cutting blade 92 complete their staggered shearing, they continue to move inward and staggeredly insert into the back edge L-shaped plate 93. Since the back edge L-shaped plate 93 is fixedly connected to the top oblique cutting blade 91 and the bottom oblique cutting blade 92, during the staggered insertion process, the back edge L-shaped plate 93 exerts pressure on the top oblique cutting blade 91 and the bottom oblique cutting blade 92. It serves as a back support and limiter, thereby improving the overall rigidity of the blade during the cutting process and reducing the slight wobbling of the blade under force. Subsequently, the oblique cutting edges of the top oblique cutting blade 91 and the bottom oblique cutting blade 92 continue to contact the oblique grinding surface of the oblique grinding stone 97. Since the grinding surface of the oblique grinding stone 97 has the same inclination angle as the oblique cutting edges of the top oblique cutting blade 91 and the bottom oblique cutting blade 92, the blade cutting edges generate sliding friction along the oblique grinding surface when they come into contact with each other. This causes the blade cutting edges to form continuous grinding contact with the oblique grinding stone 97 during the movement. At the same time, since the blade cutting edges and the oblique grinding surface are in an oblique contact relationship, a lateral component force is generated on the oblique grinding stone 97 along the direction of the long groove 94 when the blade moves forward.The force pushes the beveled whetstone 97, causing the back edge positioning block 96 to move along the elongated groove 94 and compress the return spring 95. This causes the return spring 95 to generate an elastic compression force. Meanwhile, the first rollers 98 on the upper and lower sides of the back edge positioning block 96 roll and abut against the inner wall of the elongated groove 94 during movement, thereby guiding the movement direction of the back edge positioning block 96 and reducing sliding friction resistance. This allows the back edge positioning block 96 to move stably along the elongated groove 94, while the beveled whetstone 97 approaches the back edge positioning block. The second roller 99, located on one side of the 96, rolls against the inner wall of the L-shaped back edge plate 93, providing lateral support to the beveled grinding stone 97 and preventing it from tilting during grinding. Meanwhile, the third roller 910, located at the top of the beveled grinding stone 97, rolls against the bottom of the inner wall of the L-shaped back edge plate 93, thus forming a multi-point rolling support structure with the second roller 99 and the first roller 98. This ensures that the beveled grinding stone 97 maintains a stable posture during movement and remains in contact with the top beveled blade 91 and the bottom beveled blade. The beveled cutting edge of the cutting blade 92 is stably engaged. During the reciprocating shearing motion of the top beveled cutting blade 91 and the bottom beveled cutting blade 92, the beveled cutting edge continuously slides along the beveled grinding surface of the beveled grinding stone 97, thereby continuously grinding and finishing the cutting edge. When the blade leaves the beveled grinding stone 97, the compressed return spring 95 releases its elastic potential energy to push the back edge positioning block 96 to reset the beveled grinding stone 97, so that the beveled grinding stone 97 is once again in a position adapted to the top beveled cutting blade 91 and the bottom beveled cutting blade 92. This allows for continuous automatic grinding and trimming of the oblique cutting edges of the top oblique cutting blade 91 and the bottom oblique cutting blade 92 during continuous equipment operation. This maintains the sharpness of the blade edges and ensures a neat cut surface for the electrode sheet 7, reducing edge curling or burrs. It also avoids frequent machine stops for manual sharpening, improving the continuous production capacity and cutting stability of the equipment. The positioning mechanism 8, mounted on the cutting mechanism 3, limits and positions the cutting position of the electrode sheet 7 during the cutting process to ensure cutting accuracy.

[0022] A lithium battery electrode sheet 7 cutting anti-rolling positioning device further includes a guiding mechanism 4, which is disposed on the machine body 1 and is used to guide and limit the electrode sheet 7 during the conveying process, so that the electrode sheet 7 enters the cutting area along a predetermined path. The guiding mechanism 4 includes a guiding rail 41, which is fixedly connected to the top of the machine body 1. A side drive rail 42 is fixedly connected to the side wall of the guiding rail 41. A movable rigid plate 43 is fixedly connected to the output end of the side drive rail 42. An inclined guiding surface 44 is provided on the movable rigid plate 43. A guiding reciprocating motor 45 is fixedly connected to the movable rigid plate 43. A guiding pressure plate 46 is fixedly connected to the output end of the guiding reciprocating motor 45. The guiding pressure plate 46 is parallel to the movable rigid plate 43. The top of the movable rigid plate 43 is slidably connected to the side drive rail 42. When the side drive rail 42 is working, its output end drives the fixedly connected movable rigid plate 43 to move along the direction of the guide rail 41. Since the top of the movable rigid plate 43 is slidably connected to the guide rail 41, the movable rigid plate 43 can slide smoothly on the guide rail 41. When the side drive rail 42 is started, it first drives the movable rigid plate 43 to the end position of the conveying mechanism 2, so that the electrode 7 output by the conveying mechanism 2 can enter the area where the movable rigid plate 43 is located. The inclined guide surface 44 provided on the movable rigid plate 43 first contacts the front end of the electrode 7. Since the inclined guide surface 44 is an inclined structure, when the electrode 7 moves forward under the push of the conveying mechanism 2, it will generate along the inclined guide surface 44. Lateral sliding guides the electrode 7 to the upper surface of the movable rigid plate 43, smoothly transitioning it from the conveying end of the conveying mechanism 2 to the movable rigid plate 43 and completing initial guiding and positioning. Once the electrode 7 reaches the upper surface of the movable rigid plate 43, the guide reciprocating motor 45, fixedly connected to the movable rigid plate 43, starts operating. The output of the guide reciprocating motor 45 drives the fixedly connected guide pressure plate 46 downwards. Because the guide pressure plate 46 is parallel to the movable rigid plate 43, it can evenly press the electrode 7 on the movable rigid plate 43 during downward movement, pressing the electrode 7 firmly between the movable rigid plate 43 and the guide pressure plate 46 to form a stable clamping state, thus preventing the electrode 7 from... If tilting, sliding, or shifting occurs during subsequent movement, the side drive rail 42 will restart after the electrode 7 is stably clamped, driving the movable rigid plate 43 to return to its original position along the guide rail 41. During this movement, the movable rigid plate 43 drives the electrode 7, which is pressed by the guide pressure plate 46, to move towards the cutting area, thereby stably conveying the electrode 7 to the cutting position of the cutting mechanism 3. After reaching the predetermined position, the guide reciprocating motor 45 drives the guide pressure plate 46 to reset upward, releasing the pressure on the electrode 7, allowing the electrode 7 to continue entering the cutting mechanism 3 for cutting. This is achieved through the sequential cooperation between the machine body 1, guide rail 41, side drive rail 42, movable rigid plate 43, inclined guide surface 44, guide reciprocating motor 45, and guide pressure plate 46.This allows the electrode 7 to undergo lateral guidance, transition, and pressing before being conveyed to the cutting area. This prevents positional shifts, warping, or wobbling of the electrode 7 as it enters the cutting area at the end of the conveying process. This improves the accuracy and stability of the electrode 7's position when entering the cutting mechanism 3, thereby enhancing cutting quality and reducing curling or cutting deviations during the cutting process.

[0023] A lithium battery electrode sheet 7 cutting anti-rolling positioning device further includes a picking mechanism 5, which is mounted on the machine body 1 and used to pick up the cut electrode sheet 7 and transfer it to a subsequent work station. The picking mechanism 5 includes a rigid fixing column 51, which is fixedly connected to the top of the machine body 1. A picking electric guide rail 52 is fixedly connected to the top of the rigid fixing column 51. A picking head 53 is provided at the bottom output end of the picking electric guide rail 52. An adsorption head 54 is fixedly connected to the bottom of the picking head 53. The top of the device is fixedly connected to a pickup electric guide rail 52. When energized, the pickup electric guide rail 52 generates a linear driving force, and its bottom output end drives the pickup head 53 to reciprocate along the guide direction of the pickup electric guide rail 52. This allows the pickup head 53 to move between the cutting mechanism 3 and subsequent workstations. When the electrode 7 stops at a predetermined position after being cut by the cutting mechanism 3, the pickup electric guide rail 52 first drives the pickup head 53 to move above the electrode 7, and then the pickup head 53 drives its bottom fixed... The connected adsorption head 54 approaches the electrode 7 downwards. The adsorption head 54 forms an adsorption connection with the surface of the electrode 7 through negative pressure adsorption, allowing the electrode 7 to be stably adsorbed at the bottom of the adsorption head 54. After the adsorption head 54 adsorbs the electrode 7, the electric pick-up guide rail 52 restarts and drives the pick-up head 53 to move along the guide rail. This causes the pick-up head 53 to move the adsorption head 54 and the adsorbed electrode 7 together to the predetermined subsequent working position. After reaching the subsequent working position, the adsorption head 54 releases the negative pressure adsorption, allowing the electrode 7 to be removed from the adsorption head. The bottom of the device 54 is released and falls into the designated position, thereby completing the automatic gripping and transfer of the cut electrode sheet 7. Through the sequential cooperation between the machine body 1, the rigid fixing column 51, the electric pick-up guide rail 52, the pick-up head 53, and the adsorption head 54, the cut electrode sheet 7 can be automatically picked up and transported to the subsequent work station, thereby avoiding the low efficiency and unstable positioning problems caused by manual material handling. At the same time, it ensures the stability of the electrode sheet 7 during the transfer process and improves the automation level and production efficiency of the entire lithium battery electrode sheet 7 cutting equipment.

[0024] An anti-rolling positioning device for cutting lithium battery electrode sheets 7 also includes a control panel 6. The control panel 6 is set on the machine body 1 and is used to control and adjust the operating status of the conveying mechanism 2, the cutting mechanism 3, the guiding mechanism 4 and the picking mechanism 5, so that each mechanism runs according to the set process sequence, thereby realizing the automated operation of the electrode sheet 7 from conveying, guiding, cutting to picking and transferring.

[0025] The conveying mechanism 2 includes a conveying frame 21, which is fixedly connected to the top of the machine body 1. A conveying drive device 22 is provided on the side of the conveying frame 21, and a conveyor belt 23 is provided on the top of the conveying frame 21. The conveying drive device 22 is used to drive the conveyor belt 23. After receiving the start signal from the control panel 6, the conveying drive device 22 on the side of the conveying frame 21 starts to operate and generates driving force. The conveying drive device 22 transmits the driving force to the conveyor belt 23 on the top of the conveying frame 21, so that the conveyor belt 23 continuously circulates along the length of the conveying frame 21. When the electrode 7 is placed on the conveyor belt 23, the movement of the conveyor belt 23 drives the electrode 7 to move forward along the direction of the conveying frame 21, thereby stably conveying the electrode 7 to the subsequent work station of the equipment.

[0026] The cutting mechanism 3 includes a cutting support frame 31, which is fixedly connected to the top of the machine body 1. A cutting linear motor 32 is fixedly connected to the top of the cutting support frame 31. A telescopic rod 33 is fixedly connected to the bottom of the inner wall of the cutting support frame 31. A bottom hollow frame 34 is fixedly connected to the end of the telescopic rod 33 away from the bottom of the inner wall of the cutting support frame 31. A top hollow frame 35 is fixedly connected to the output end of the cutting linear motor 32. The inner wall of the top hollow frame 35 is fixedly connected to the top oblique cutting blade 91. The inner wall of the bottom hollow frame 34 is fixedly connected to the bottom oblique cutting blade 92. Bottom guide rails 36 are fixedly connected to both sides of the bottom hollow frame 34. Top guide rails 37 are fixedly connected to both sides of the top hollow frame 35. A rigid support column 38 is fixedly connected to the support frame 31. A rigid connecting rod 39 is rotatably connected to the top of the rigid support column 38. Rotating cylindrical ends 310 are rotatably connected to both ends of the rigid connecting rod 39. The top rotating cylindrical end 310 is sleeved with the inner wall of the top guide rail 37, and the bottom rotating cylindrical end 310 is sleeved with the inner wall of the bottom guide rail 36. A cutting linear motor 32 fixedly connected to the top of the cutting support frame 31 generates a linear driving force after being energized. The output end of the cutting linear motor 32 moves downward and drives the fixedly connected top hollow frame 35 to move downward synchronously. During the movement, the top hollow frame 35 drives the top guide rails 37 fixedly connected to both sides to move downward as a whole. During the process, the top rotating cylindrical end 310, which is fitted into the inner wall of the rigid support column 38, moves downward. Since the top rotating cylindrical end 310 is rotatably connected to the end of the rigid connecting rod 39, the downward movement of the top rotating cylindrical end 310 causes the rigid connecting rod 39 to swing around the top rotating connection point of the rigid support column 38. During this swinging motion, the rigid connecting rod 39 transmits motion to the bottom rotating cylindrical end 310, which is rotatably connected to its other end. This causes the bottom rotating cylindrical end 310 to move upward within the inner wall of the bottom guide rail 36. The upward movement of the bottom rotating cylindrical end 310 exerts a lifting effect on the bottom guide rail 36, thereby causing the bottom hollow frame 34, which is fixedly connected to the bottom guide rail 36, to move upward as a whole. During its upward movement, the hollow frame 34 moves synchronously upward via the bottom oblique cutting blade 92 fixedly connected to its inner wall. Simultaneously, the top hollow frame 35 moves downward under the drive of the cutting linear motor 32 and moves synchronously downward via the top oblique cutting blade 91 fixedly connected to its inner wall. This causes the top oblique cutting blade 91 and the bottom oblique cutting blade 92 to move in opposite directions, cutting the electrode 7 located between them. During this process, the linear drive of the cutting linear motor 32 is transmitted sequentially through the top hollow frame 35, the top guide rail 37, the top rotating cylindrical end 310, the rigid connecting rod 39, the bottom rotating cylindrical end 310, and the bottom guide rail 36, enabling the bottom hollow frame 34 to move in conjunction with the top hollow frame 35.This causes the top beveled blade 91 and the bottom beveled blade 92 to move simultaneously towards the middle area and jointly complete the shearing and cutting of the electrode 7. When the cutting linear motor 32 returns, the top hollow frame 35 resets upward, and the top guide rail 37 drives the top rotating cylindrical end 310 to move upward. The top rotating cylindrical end 310 then drives the rigid connecting rod 39 to swing in the opposite direction and causes the bottom rotating cylindrical end 310 to move downward in the bottom guide rail 36. This causes the bottom guide rail 36 to drive the bottom hollow frame 34 to reset downward, while the telescopic rod 3... 3. The release of elastic force assists the bottom hollow frame 34 in resetting, allowing the top beveled blade 91 and bottom beveled blade 92 to separate again and return to their initial positions, so that the electrode 7 can enter the cutting area again for further cutting. This transmission structure utilizes the unidirectional drive of the cutting linear motor 32 to achieve synchronous, opposite-direction movement of the upper and lower blades, thereby improving cutting efficiency and ensuring the alignment accuracy of the top and bottom beveled blades 91 and 92. This reduces blade offset caused by unilateral force, improving the cutting quality of the electrode 7 and the stability of equipment operation.

[0027] The positioning mechanism 8 includes a top guide post 81, which is slidably connected to the inner wall of the top hollow frame 35. A bottom guide post 83 is slidably connected to the inner wall of the bottom hollow frame 34. A bottom rigid pressure plate 84 is fixedly connected to the top of the bottom guide post 83, and a top rigid pressure plate 82 is fixedly connected to the bottom of the top guide post 81. A top pressure plate spring 85 is connected between the top guide post 81 and the inner wall of the top hollow frame 35, and a bottom pressure plate spring 86 is connected between the inner wall of the bottom hollow frame 34 and the bottom guide post 83. The top surface of the bottom pressure plate spring 86 is higher than the cutting edge of the bottom beveled blade 92, and the bottom surface of the top rigid pressure plate 82 is lower than the cutting edge of the top beveled blade 91. During the operation of the cutting mechanism 3, the electrode 7 is conveyed... The electrode 7 is cut between the top bevel cutting blade 91 and the bottom bevel cutting blade 92. Simultaneously, the positioning mechanism 8 begins to position and hold the electrode 7. A top guide post 81 is slidably connected to the inner wall of the top hollow frame 35. The top guide post 81 can slide up and down along the inner wall of the top hollow frame 35 to form a guiding and positioning structure. A top rigid pressure plate 82 is fixedly connected to the bottom of the top guide post 81. The top rigid pressure plate 82 is located near the top bevel cutting blade 91 and is used to hold the upper surface of the electrode 7. A top pressure plate spring 85 is connected between the top guide post 81 and the inner wall of the top hollow frame 35. The top pressure plate spring 85 provides a downward elastic preload to the top guide post 81, ensuring that the top rigid pressure plate 82 remains in its initial state. The bottom hollow frame 34 has a downward pressing tendency, and a bottom guide post 83 is slidably connected to the inner wall of the bottom hollow frame 34. The bottom guide post 83 can slide up and down along the inner wall of the bottom hollow frame 34. The top of the bottom guide post 83 is fixedly connected to a bottom rigid pressure plate 84, which is used to support and position the lower surface of the electrode 7. At the same time, a bottom pressure plate spring 86 is connected between the inner wall of the bottom hollow frame 34 and the bottom guide post 83. The bottom pressure plate spring 86 provides an upward elastic support force to the bottom guide post 83, so that the bottom rigid pressure plate 84 always has an upward pressing tendency. The top surface of the bottom pressure plate spring 86 is higher than the cutting edge of the bottom beveled blade 92, while the bottom surface of the top rigid pressure plate 82 is lower than the cutting edge of the top beveled blade 91. When electrode 7 is conveyed to the cutting area, it is first lifted upward by the bottom hard pressure plate 84 and pressed downward by the top hard pressure plate 82, thus stably clamping electrode 7 between the top and bottom hard pressure plates 84 and keeping it flat. When the cutting mechanism 3 drives the top beveled blade 91 and the bottom beveled blade 92 to move towards each other, their cutting edges gradually approach electrode 7. Since the bottom surface of the top hard pressure plate 82 is lower than the cutting edge of the top beveled blade 91 and the top surface of the bottom pressure plate spring 86 is higher than the cutting edge of the bottom beveled blade 92, electrode 7 is pressed and positioned before the blades contact, thus preventing electrode 7 from warping, slipping, or locally lifting during the cutting process.As the top beveled blade 91 continues to move downwards, the top rigid pressure plate 82, under the combined action of the electrode 7 and the blade, pushes the top guide post 81 upwards and compresses the top pressure plate spring 85. Simultaneously, when the bottom beveled blade 92 contacts the electrode 7, the bottom rigid pressure plate 84 is subjected to compressive force, causing the bottom guide post 83 to move downwards and compress the bottom pressure plate spring 86. This allows the top rigid pressure plate 82 and the bottom rigid pressure plate 84 to maintain clamping force while generating a certain elastic clearance space, enabling the top beveled blade 91 and the bottom beveled blade 92 to smoothly complete the shearing of the electrode 7. After the shearing is completed, the top pressure plate spring 85 and the bottom pressure plate spring 86 release their elastic force, respectively pushing the top guide post 81 and the bottom guide post 83 back to their original positions. This allows the top rigid pressure plate 82 and the bottom rigid pressure plate 84 to return to their initial pressing positions. Through the top guide post 81 and the top rigid pressure plate... The cooperation between the top pressure plate spring 85, the bottom guide post 83, the bottom rigid pressure plate 84, and the bottom pressure plate spring 86 ensures that the electrode sheet 7 maintains stable pressure and accurate positioning during the cutting process. This effectively prevents the electrode sheet 7 from curling, warping, or shifting due to uneven force during cutting, improving the flatness and cutting accuracy of the electrode sheet 7 and enhancing the overall processing stability of the lithium battery electrode sheet 7 cutting equipment. The top guide post 81 array has multiple sets, and the bottom guide post 83 array has multiple sets. By arranging the top guide post 81 and bottom guide post 83 in multiple arrays, uniform support and pressure can be achieved in the width direction of the electrode sheet 7, ensuring that the electrode sheet 7 remains flat and stably positioned during conveying and cutting, preventing warping, slippage, or curling of the electrode sheet 7, thereby improving cutting accuracy and product consistency. This is especially suitable for cutting wide electrode sheets 7. Multiple arrays can also distribute pressure, preventing deformation or damage to the electrode 7 caused by single-point pressure. The top beveled blade 91 and bottom beveled blade 92 are detachable for replacement and maintenance, eliminating the need to replace the entire cutting mechanism 3, reducing equipment downtime, improving production efficiency, and extending equipment lifespan.

[0028] A lithium battery electrode cutting anti-rolling positioning process further includes the following processes: Step 1: Preparation stage. Start the equipment through control panel 6. Control panel 6 is connected to conveying mechanism 2, guiding mechanism 4, cutting mechanism 3, positioning mechanism 8, stabilizing mechanism 9 and picking mechanism 5. It is used to send start signals to adjust the operating status of each mechanism, ensuring that all mechanisms are in the initial position and coordinated. Place electrode 7 on conveyor belt 23 of conveying mechanism 2. Conveyor belt 23 is connected to transmission drive device 22. Transmission drive device 22 receives signals from control panel 6 and generates driving force to prepare to convey electrode 7 along the preset path. This step is used to initialize equipment parameters to match the specifications of electrode 7, avoid position deviation during start-up, and improve overall automation coordination. Step 2: Conveying stage. Conveying mechanism 2 is started, and transmission drive device 22 is connected to conveyor belt 23. Transmission drive device 22 generates driving force to drive conveyor belt 23 to circulate. Conveyor belt 23 carries electrode 7 and moves it forward along the direction of transmission frame 21 to the area of ​​guide mechanism 4. Transmission frame 21 is fixed on machine body 1 to support the entire conveying process. This step is used to continuously and stably convey electrode 7, ensuring that electrode 7 enters the next mechanism flat, improving conveying efficiency and position accuracy. Step 3: Guiding stage. The guiding mechanism 4 works, the side drive rail 42 is connected to the movable rigid plate 43, and the output end of the side drive rail 42 drives the movable rigid plate 43 to move along the guiding rail 41 to the end of the conveying mechanism 2. The guiding rail 41 is fixed on the machine body 1 for guidance. The inclined guiding surface 44 on the movable rigid plate 43 contacts the front end of the electrode 7 and guides it to transition to the upper surface of the movable rigid plate 43. The movable rigid plate 43 is connected to the guiding reciprocating motor 45, and the output end of the guiding reciprocating motor 45 is connected to the guiding pressure plate 46. The guiding reciprocating motor 45 drives the guiding pressure plate 46 to press the electrode 7 downward in parallel to form a clamp. The side drive rail 42 then drives the movable rigid plate 43 and the electrode 7 back to the position of the cutting mechanism 3. The guiding pressure plate 46 returns to its original position and releases upward. This step is used for lateral guidance, transition support and pressing to fix the electrode 7, to avoid deviation or warping when entering the cutting area, and to improve the stability and accuracy when entering the cutting area. Step 4: Positioning Stage. The cutting linear motor 32 is fixedly connected to the top of the cutting support frame 31, generating a downward linear driving force that drives the top hollow frame 35 to move downwards synchronously. The top hollow frame 35 drives the top guide rails 37 fixedly connected on both sides to move downwards as a whole. The top rotating cylindrical end 310 is sleeved on the inner wall of the top guide rail 37, driving it to move downwards. The top rotating cylindrical end 310 is rotatably connected to one end of the rigid connecting rod 39, causing the rigid connecting rod 39 to swing around the top rotating connection point of the rigid support column 38 fixed on the cutting support frame 31. The swinging motion of the rigid connecting rod 39 transmits the motion... The bottom rotating cylindrical end 310, which is rotatably connected to the other end, moves upward within the inner wall of the bottom guide rail 36. This upward movement of the bottom rotating cylindrical end 310 lifts the bottom guide rail 36, causing the bottom hollow frame 34, which is fixedly connected to the bottom guide rail 36 on both sides, to move upward as a whole. This causes the top hollow frame 35 to move downward and the bottom hollow frame 34 to move upward, bringing them closer together. The top beveled blade 91, fixed to the inner wall of the top hollow frame 35, moves downward synchronously, while the bottom beveled blade 92, fixed to the inner wall of the bottom hollow frame 34, moves upward synchronously. The blade edges gradually approach the... The electrode 7 between the two is pre-clamped by the top hard pressure plate 82 and the bottom hard pressure plate 84 before the blades contact each other, because the bottom surface of the top hard pressure plate 82 is lower than the cutting edge of the top oblique cutting blade 91 and the top surface of the bottom hard pressure plate 84 is higher than the cutting edge of the bottom oblique cutting blade 92. When the blades contact the electrode 7, the combined force of the hollow frame approaching each other is transmitted through the blades to the electrode 7, and then to the pressure plates. The top oblique cutting blade 91 presses the electrode 7 downward, pushes the top hard pressure plate 82 to move upward, and drives the fixedly connected top guide post 81 to slide upward along the inner wall of the top hollow frame 35, compressing the connection to the top guide post 81. The top pressure plate spring 85 between the column 81 and the inner wall of the top hollow frame 35 creates elastic clearance. The bottom oblique cutting blade 92 presses the electrode 7 upward, pushing the bottom hard pressure plate 84 downward. This causes the fixedly connected bottom guide column 83 to slide downward along the inner wall of the bottom hollow frame 34, compressing the bottom pressure plate spring 86 connected between the bottom guide column 83 and the inner wall of the bottom hollow frame 34, creating elastic clearance. This achieves compression and buffering under the drive of the hollow frames moving closer together, ensuring stable positioning of the electrode 7 during the shearing process and preventing edge curling or displacement. The multiple arrays of guide columns and pressure plates evenly distribute the force, improving the uniformity of compression. Step 5: Cutting Stage. During the operation of the cutting mechanism 3, the top beveled blade 91 and the bottom beveled blade 92 move relative to each other and perform beveled shearing on the electrode 7. The cutting edges of the top beveled blade 91 and the bottom beveled blade 92 intersect to form a shearing method similar to scissors, so that the electrode 7 is cut from one side to the other as the two cutting edges gradually come into contact. This allows the shearing force to be gradually transmitted along the cutting line, which can effectively reduce the instantaneous impact force and avoid the entire cutting edge from squeezing the electrode 7 at the same time. This reduces the possibility of the edge material of the electrode 7 being squeezed and stretched, resulting in curling. At the same time, beveled shearing can also release the material deformation generated during the cutting process along the direction of the cutting edge, improving the flatness and stability of the cut surface. When the top beveled blade 91 and bottom beveled blade 92 complete the staggered shearing, they continue to move inward and staggeredly insert into the back edge L-shaped plate 93. Since the back edge L-shaped plate 93 is fixedly connected to the top beveled blade 91 and bottom beveled blade 92, it provides back support and limits the top beveled blade 91 and bottom beveled blade 92 during the staggered insertion process. This improves the overall rigidity of the blades during the shearing process and reduces the slight swaying of the blades under force. Subsequently, the beveled cutting edges of the top beveled blade 91 and bottom beveled blade 92 continue to abut against the beveled grinding surface of the beveled grinding stone 97. The beveled cutting edges of the blades 92 have the same angle of inclination, so when they come into contact, the blade edges slide along the beveled grinding surface. During movement, the blade edges form continuous grinding contact with the beveled grinding stone 97. Simultaneously, because the blade edges and the beveled grinding surface are in inclined contact, a lateral force is generated on the beveled grinding stone 97 along the direction of the elongated groove 94 as the blade moves forward. This force pushes the beveled grinding stone 97, causing the back edge positioning block 96 to move along the elongated groove 94 and compress the return spring 95. The return spring 95 generates an elastic compressive force. Meanwhile, the first rollers 98 on the upper and lower sides of the back edge positioning block 96 roll and abut against the inner wall of the elongated groove 94 during movement, thus affecting the movement of the back edge positioning block 96. The movement direction is guided and sliding friction resistance is reduced, allowing the back edge positioning block 96 to move stably along the elongated groove 94. Simultaneously, the second roller 99 of the beveled grinding stone 97, located near the back edge positioning block 96, rolls against the inner wall of the back edge L-shaped plate 93, providing lateral support to prevent the beveled grinding stone 97 from tilting during grinding. The third roller 910 at the top of the beveled grinding stone 97 rolls against the bottom of the inner wall of the back edge L-shaped plate 93, thus forming a multi-point rolling support structure with the second roller 99 and the first roller 98. The beveled grinding stone 97 maintains a stable posture throughout its movement and stably adheres to the beveled edges of the top and bottom beveled blades 91 and 92.During the reciprocating shearing motion of the top beveled blade 91 and the bottom beveled blade 92, their beveled cutting edges continuously slide along the beveled grinding surface of the beveled grinding stone 97, thereby continuously grinding and finishing the cutting edges. When the blade leaves the beveled grinding stone 97, the compressed return spring 95 releases its elastic potential energy to push the back edge positioning block 96, causing the beveled grinding stone 97 to return to its original position, adapting to the positions of the top beveled blade 91 and the bottom beveled blade 92. Thus, during continuous operation, the beveled cutting edges of the top beveled blade 91 and the bottom beveled blade 92 are continuously and automatically ground and finished, maintaining the sharpness of the blade edges and ensuring a neat cut surface for the electrode sheet 7, reducing edge curling or burrs on the electrode sheet 7, while avoiding frequent machine stops for manual sharpening, improving the continuous production capacity and cutting stability of the equipment. Step Six: Pick-up Stage. After cutting, the pick-up mechanism 5 is activated. The rigid fixing column 51 is fixed on the machine body 1 and connected to the pick-up electric guide rail 52. The bottom output end of the pick-up electric guide rail 52 is connected to the pick-up head 53. The bottom of the pick-up head 53 is connected to the suction head 54. The pick-up electric guide rail 52 drives the pick-up head 53 to move above the electrode 7. The suction head 54 uses negative pressure to suction the electrode 7. The pick-up electric guide rail 52 then drives the pick-up head 53 to transfer the electrode 7 to the subsequent station for release. This step is used to automatically pick up and transfer the cut electrode 7, avoiding manual intervention, improving efficiency and stability, and enhancing the level of automated production.

10. A lithium battery electrode cutting anti-rolling positioning process, characterized in that: The lithium battery electrode cutting anti-rolling positioning equipment applied to any one of claims 1-9 further includes the following process: Step 1: Preparation stage. Start the equipment through the control panel (6). The control panel (6) is connected to the conveying mechanism (2), guiding mechanism (4), cutting mechanism (3), positioning mechanism (8), stabilizing mechanism (9) and picking mechanism (5). Place the electrode (7) on the conveyor belt (23) of the conveying mechanism (2). The conveyor belt (23) is connected to the transmission drive device (22). The transmission drive device (22) receives the signal from the control panel (6) and generates driving force to prepare to transport the electrode (7) along the preset path. Step 2: Conveying stage, the conveying mechanism (2) is started, the transmission drive device (22) is connected to the conveyor belt (23), the transmission drive device (22) generates driving force to drive the conveyor belt (23) to circulate, the conveyor belt (23) carries the electrode (7) and moves it forward along the direction of the transmission frame (21) to the area of ​​the guide mechanism (4); Step 3: Guiding stage. The guiding mechanism (4) works. The side drive rail (42) is connected to the movable rigid plate (43). The output end of the side drive rail (42) drives the movable rigid plate (43) to move along the guiding rail (41) to the end of the conveying mechanism (2). The inclined guiding surface (44) on the movable rigid plate (43) contacts the front end of the electrode (7) and guides it to transition to the upper surface of the movable rigid plate (43). The movable rigid plate (43) is connected to the guiding reciprocating motor (45). The output end of the guiding reciprocating motor (45) is connected to the guiding pressure plate (46). The guiding reciprocating motor (45) drives the guiding pressure plate (46) to press the electrode (7) downward in parallel to form a clamp. The side drive rail (42) then drives the movable rigid plate (43) and the electrode (7) to return to the position of the cutting mechanism (3). The guiding pressure plate (46) resets upward and releases. Step 4: Positioning stage. The cutting linear motor (32) is fixedly connected to the top of the cutting support frame (31), generating a downward linear driving force, which drives the top hollow frame (35) to move downward synchronously. The top hollow frame (35) drives the top guide rails (37) fixedly connected on both sides to move downward as a whole. The top rotating cylindrical end (310) is sleeved on the inner wall of the top guide rail (37), which drives it to move downward. The top rotating cylindrical end (310) is rotatably connected to one end of the rigid connecting rod (39), causing the rigid connecting rod (39) to swing around the top rotating connection point of the rigid support column (38) fixed on the cutting support frame (31). The rigid connecting rod (39) rotates and swings, transmitting the motion to the bottom rotating cylindrical end (310) connected to the other end. This causes the bottom rotating cylindrical end (310) to move upward within the inner wall of the bottom guide rail (36). The upward movement of the bottom rotating cylindrical end (310) lifts the bottom guide rail (36), causing the bottom hollow frame (34), which is fixedly connected to the bottom guide rail (36) on both sides, to move upward as a whole. This causes the top hollow frame (35) to move downward and the bottom hollow frame (34) to move upward, forming a mutual approaching motion. The top beveled blade (91) fixed to the inner wall of the top hollow frame (35) moves downward synchronously, and the bottom... The bottom beveled blade (92) is fixed to the inner wall of the hollow frame (34) and moves upward synchronously. The blade edge gradually approaches the electrode (7) located between the two. Since the bottom surface of the top hard pressure plate (82) is lower than the edge of the top beveled blade (91) and the top surface of the bottom hard pressure plate (84) is higher than the edge of the bottom beveled blade (92), the electrode (7) has been pre-tightly clamped by the top hard pressure plate (82) and the bottom hard pressure plate (84) before the blade contacts the electrode (7). When the blade contacts the electrode (7), the resultant force of the hollow frame approaching each other is transmitted through the blade to the electrode (7) and then to the pressure plate. The top blade (91) presses the electrode (7) downward and pushes it. The top rigid pressure plate (82) moves upward, causing the fixedly connected top guide post (81) to slide upward along the inner wall of the top hollow frame (35), compressing the top pressure plate spring (85) connected between the top guide post (81) and the inner wall of the top hollow frame (35), generating elastic clearance. The bottom blade (92) presses the electrode plate (7) upward, pushing the bottom rigid pressure plate (84) downward, causing the fixedly connected bottom guide post (83) to slide downward along the inner wall of the bottom hollow frame (34), compressing the bottom pressure plate spring (86) connected between the bottom guide post (83) and the inner wall of the bottom hollow frame (34), generating elastic clearance. Step 5: Cutting stage. During the operation of the cutting mechanism (3), the top beveled blade (91) and the bottom beveled blade (92) move relative to each other and bevel the electrode (7) at an angle. The cutting edges of the top beveled blade (91) and the bottom beveled blade (92) intersect to form a cutting method similar to scissors. As the cutting edges of the two sides gradually come into contact, the electrode (7) is cut from one side to the other in sequence. This allows the shearing force to be gradually transmitted along the cutting line, which can effectively reduce the instantaneous impact force and avoid the entire cutting edge from squeezing the electrode (7) at the same time. This reduces the situation where the edge material of the electrode (7) is squeezed and stretched, resulting in curling. At the same time, the beveled shearing can also release the material deformation generated during the cutting process along the cutting edge direction, improving the flatness of the cut surface. To ensure stability, when the top bevel cutting blade (91) and the bottom bevel cutting blade (92) complete the staggered shearing, the top bevel cutting blade (91) and the bottom bevel cutting blade (92) continue to move inward and staggeredly insert into the back edge L-shaped plate (93). Since the back edge L-shaped plate (93) is fixedly connected to the top bevel cutting blade (91) and the bottom bevel cutting blade (92), the back edge L-shaped plate (93) provides back support and limit for the top bevel cutting blade (91) and the bottom bevel cutting blade (92) during the staggered insertion process, thereby improving the overall rigidity of the blade during the shearing process and reducing the slight swaying of the blade when under force. Subsequently, the beveled cutting edges of the top bevel cutting blade (91) and the bottom bevel cutting blade (92) continue to cut with the beveled whetstone (97). The oblique grinding surfaces of the beveled whetstone (97) come into contact with each other. Since the angle of inclination of the beveled cutting edge of the whetstone (97) is the same as that of the top beveled cutting edge (91) and the bottom beveled cutting edge (92), the cutting edge of the blade will slide along the oblique grinding surface when they come into contact. During the movement, the cutting edge of the blade will form a continuous grinding contact with the beveled whetstone (97). At the same time, since the cutting edge of the blade and the oblique grinding surface are in an oblique contact relationship, a transverse component force will be generated on the beveled whetstone (97) along the direction of the long groove (94) when the blade moves forward. This component force pushes the beveled whetstone (97) to drive the back edge positioning block (96) to move along the direction of the long groove (94) and compress the return spring (95). The return spring (95) generates an elastic compressive force. The first rollers (98) on the upper and lower sides of the back edge positioning block (96) roll against the inner wall of the long groove (94) during movement, thereby guiding the movement direction of the back edge positioning block (96) and reducing sliding friction resistance, so that the back edge positioning block (96) can move stably along the direction of the long groove (94). At the same time, the second roller (99) on the side of the beveled grinding stone (97) near the back edge positioning block (96) rolls against the inner side of the back edge L-shaped plate (93), providing lateral support for the beveled grinding stone (97) and preventing the beveled grinding stone (97) from tilting during grinding. The third roller (910) on the top of the beveled grinding stone (97) rolls against the bottom of the inner wall of the back edge L-shaped plate (93).Thus, a multi-point rolling support structure is formed with the second roller (99) and the first roller (98). The oblique cutting whetstone (97) maintains a stable posture during movement and is stably attached to the oblique cutting edges of the top oblique cutting blade (91) and the bottom oblique cutting blade (92). During the reciprocating shearing motion of the top oblique cutting blade (91) and the bottom oblique cutting blade (92), its oblique cutting edge continuously slides along the oblique grinding surface of the oblique cutting whetstone (97), thereby continuously grinding and finishing the cutting edge. When the blade leaves the oblique cutting whetstone (97), the compressed return spring (95) releases elastic potential energy to push the back edge positioning block (96) to drive the oblique cutting whetstone (97) to reset, so that the oblique cutting whetstone (97) is once again in a position that is compatible with the top oblique cutting blade (91) and the bottom oblique cutting blade (92). Step 6: Pick-up stage. After the cutting is completed, the pick-up mechanism (5) is started. The rigid fixing column (51) is fixed on the machine body (1) and connected to the pick-up electric guide rail (52). The bottom output end of the pick-up electric guide rail (52) is connected to the pick-up head (53). The bottom of the pick-up head (53) is connected to the adsorption head (54). The pick-up electric guide rail (52) drives the pick-up head (53) to move above the electrode (7). The adsorption head (54) adsorbs the electrode (7) with negative pressure. The pick-up electric guide rail (52) then drives the pick-up head (53) to transfer the electrode (7) to the subsequent station for release.
