Abstract
Description
Technical Field
[0001] This application relates to the field of battery manufacturing technology, specifically to a cutting system and a battery production system. Background Technology
[0002] During the die-cutting process of battery electrodes, excess material needs to be cut off, and the leftover material is recycled using negative pressure. During cutting, the leftover material is prone to vibration under negative pressure, resulting in uneven cut edges and burrs. These burrs can pose a risk of short circuits, affecting the quality of battery production. Utility Model Content
[0003] In view of the above problems, this application provides a cutting system in which the first plate is tilted to provide auxiliary support for the cut residue, thereby reducing the speed at which the residue moves downward and reducing the burrs generated on the cut edge of the electrode, making the cut edge of the electrode smoother.
[0004] In a first aspect, this application provides a cutting system, comprising:
[0005] Cutting device;
[0006] The anti-vibration device includes a main body and a receiving plate. A cutting device is provided on one side of the main body. The cutting device is configured to cut the workpiece to be cut on the surface of the main body. The main body is configured to provide support to the workpiece to be cut. The receiving plate is connected to the bottom of the main body. The receiving plate includes a first plate body. The first plate body is inclined downward and is used to receive and guide the residual material of the workpiece to be cut off by the cutting device.
[0007] The part to be cut can be the battery electrode sheet. The cutting device cuts the side of the electrode sheet, so that the cut residue falls in strip shape. The first plate is set to be inclined downward, which can provide a certain support for the residue of the electrode sheet, so as to reduce the vibration of the residue of the electrode sheet during the cutting process, thereby making the edge of the electrode sheet cut smoother, reducing the burrs generated on the edge of the electrode sheet cut, which is conducive to improving the production quality of the battery.
[0008] In some embodiments, the obtuse angle between the height direction of the anti-shake device and the first plate is A, and the value of A ranges from 120° to 160°.
[0009] This allows the excess material of the electrode sheet to adhere more smoothly to the first plate under the action of friction, thereby reducing the burrs generated at the cutting edge of the electrode sheet. At the same time, it allows the electrode sheet to slide down under its own weight after cutting and be discharged from the receiving plate, so as to facilitate the next cutting and recycling of the receiving plate.
[0010] In some embodiments, the value of A ranges from 120° to 130°.
[0011] Setting A within the above-mentioned range increases the inclination of the first plate (compared to 160°). Under the influence of gravity, the contact area between the excess material and the plate increases, enhancing friction and making it easier for the excess material to adhere smoothly to the surface of the first plate. An inclination angle of 120°-130° stabilizes the excess material, reducing its vibration and resulting in a smoother cutting edge and fewer burrs.
[0012] In some embodiments, the receiving plate further includes a second plate body located on top of the first plate body, and the second plate body is set at an obtuse angle to the first plate body.
[0013] The first plate and the second plate are set at an obtuse angle. On the one hand, this can give the receiving plate higher strength. After the receiving plate is installed in the main body, A can be kept within the set angle range to ensure the cutting effect. On the other hand, it can allow the first plate to avoid the electrode sheet, so as to reduce the impact on the electrode sheet during the cutting process.
[0014] In some embodiments, the second plate is parallel to the height direction of the anti-shake device.
[0015] Therefore, the second plate can be used as a positioning reference, maintaining an angle A between the second plate and the first plate. This ensures that the angle A between the first plate and the height direction of the anti-vibration device is also A, facilitating manufacturing and installation. Furthermore, it reduces the accumulation of excess material on the second plate, allowing the receiving plate to continuously support the excess material.
[0016] In some embodiments, the receiving plate includes a retaining edge; the first plate body is connected to retaining edges on both sides along the first direction, and / or the second plate body is connected to retaining edges on both sides along the first direction.
[0017] The first direction is perpendicular to the height direction of the second plate and the anti-shake device, respectively.
[0018] The edge guards guide the scrap material, allowing it to exit from the discharge end of the receiving plate and preventing it from accumulating and clogging on the plate, thus enabling the cutting device to operate continuously.
[0019] In some embodiments, the first plate is provided with adsorption holes, which are configured to adsorb residual material in a negative pressure manner.
[0020] This allows the scrap material to be flatly attached to the upper surface of the first plate, so that the first plate can provide greater support for the scrap material, reduce the vibration of the scrap material during the cutting process, thereby reducing the burrs generated at the cutting edge and improving the cutting quality of the electrode sheet.
[0021] In some embodiments, the first plate is provided with a plurality of adsorption holes, which are spaced apart on the first plate.
[0022] Multiple adsorption holes can further improve the support of the first plate for the scrap material, so that the scrap material can be more evenly attached to the first plate, thereby reducing the burrs generated during the cutting process.
[0023] In some embodiments, the area of the adsorption pores ranges from 0.79 cm². 2 -7cm 2 .
[0024] Setting the area of the adsorption pores within the above range can reduce the possibility of residual material clogging the adsorption pores and passing through the adsorption pores, allowing the residual material to adhere better to the first plate.
[0025] In some embodiments, the body includes a conveyor belt conveying mechanism, the conveyor belt conveying mechanism includes a conveyor belt, the conveyor belt is configured to abut against the workpiece to be cut, and the cutting device is configured to cut the workpiece to be cut on the surface of the conveyor belt.
[0026] By conveying the workpiece to be cut by a conveyor belt, on the one hand, it can provide support to the workpiece to be cut, so as to reduce the vibration of the workpiece to be cut during the cutting process and make the cutting edge smoother. On the other hand, it can keep the workpiece to be cut and the conveyor belt moving synchronously, so as to reduce the damage to the electrode caused by the relative slippage between the two.
[0027] In some embodiments, the conveyor belt's transport direction is the height direction of the anti-vibration device.
[0028] This allows the cut scraps to fall directly onto the receiving plate under their own weight, making them easy to recycle.
[0029] In some embodiments, the cutting system further includes a winding roller located on the side of the anti-vibration device opposite to the cutting device, and the winding roller is configured to wind up the portion of the workpiece remaining after cutting.
[0030] This makes it convenient to wind the cut parts.
[0031] In some embodiments, the cutting system further includes a guide roller located above the anti-vibration device. The guide roller is configured to guide the received workpiece to be cut to the feed end of the anti-vibration device. The guide roller and the winding roller together provide tension to the workpiece to be cut so that a portion of the workpiece can come into contact with the anti-vibration device.
[0032] The combined tension of the guide roller and the winding roller keeps the workpiece taut and allows it to adhere to the main body. When conveying and cutting are performed simultaneously, the vibration of the workpiece can be reduced, resulting in a smoother cutting edge and reduced burr formation.
[0033] In some embodiments, the cutting system further includes a negative pressure recovery line located below the receiving plate, the negative pressure recovery line being configured to draw in residual material in a negative pressure manner.
[0034] The negative pressure generated by the negative pressure recovery pipeline draws the cut-off residue into the pipeline for subsequent processing.
[0035] Secondly, this application provides a battery production system, including the cutting system of the first aspect, wherein the part to be cut is an electrode sheet.
[0036] Since the battery production system includes all the technical features of the aforementioned cutting system, and its effect is the same as described above, it will not be repeated here.
[0037] The above description is only an overview of the technical solution of this application.

[0059] During the die-cutting process of battery electrodes, excess material needs to be cut off by a cutting device, and the remaining material is then collected below the cutting device using negative pressure. To improve production efficiency, the electrodes are cut and conveyed simultaneously. In this case, the remaining material is prone to shaking under its own gravity and the suction force of the negative pressure, resulting in uneven cut edges and burrs. These burrs can pose a risk of short circuits, affecting the quality of battery production.
[0060] In view of this, this application provides a cutting system in which the first plate is inclined downwards, which can provide a certain support for the residual material of the electrode sheet, reduce the vibration of the residual material during the electrode sheet cutting process, thereby making the edge of the electrode sheet cut smoother, reducing the burrs generated at the edge of the electrode sheet cutting, and improving the production quality of the battery.
[0061] The cutting device of this application can be used for, but is not limited to, cutting electrodes for lithium batteries.
[0062] For ease of explanation, the following embodiments use a cutting system from some embodiments of this application as an example.
[0063] Please refer to Figures 1-3 The cutting system includes a cutting device 10 and a vibration stabilization device 20. The vibration stabilization device 20 includes a body 21 and a receiving plate 22. The cutting device 10 is provided on one side of the body 21. The cutting device 10 is configured to cut the workpiece 50 to be cut on the surface of the body 21. The body 21 is configured to provide support to the workpiece 50 to be cut. The receiving plate 22 is connected to the bottom of the body 21. The receiving plate 22 includes a first plate 221. The first plate 221 is inclined downward and is used to receive and guide the remaining material of the workpiece 50 cut off by the cutting device 10.
[0064] The cutting device 10 includes either a laser cutter or a blade. The workpiece 50 can be cut by a laser emitted from the laser cutter, or the workpiece 50 can be cut by a blade fixed on a bracket.
[0065] The part to be cut 50 can be an electrode sheet or other material strips, such as plastic film or metal strips.
[0066] The body 21 can serve as an auxiliary support during the cutting process to reduce vibration of the workpiece 50 during cutting. The body 21 can be a conveying component with support rollers or a conveyor belt 211. On the one hand, it can provide support during the movement and cutting of the workpiece 50; on the other hand, it can generally maintain synchronization with the workpiece 50 to reduce wear caused by relative slippage between the workpiece 50 and the contact surface. When the surface quality requirements of the workpiece 50 are not high, the body 21 can be a flat support plate, which provides support force to the workpiece 50.
[0067] The receiving plate 22 and the main body 21 can be fixed by means of riveting, welding or detachable connection. The detachable connection between the receiving plate 22 and the main body 21 includes, but is not limited to, screw connection or snap-fit connection.
[0068] In one example, the first plate 221 can be directly connected to the body 21 via fasteners. In another example, the first plate 221 can be connected to the body 21 via an adapter.
[0069] The part to be cut 50 can be a battery electrode. The cutting device 10 cuts the side of the electrode, so that the cut residue falls in strip shape. The first plate 221 is tilted downward to provide a certain support for the residue of the electrode, thereby reducing the vibration of the residue during the electrode cutting process. This makes the edge of the electrode cut smoother, reducing the burrs generated at the edge of the electrode cut, which is beneficial to improving the production quality of the battery.
[0070] In some embodiments, please refer to Figure 3The obtuse angle between the height direction Z of the anti-shake device 20 and the first plate 221 is A, and the value of A ranges from 120° to 160°.
[0071] This allows the excess material of the electrode sheet to adhere more smoothly to the first plate 221 under the action of friction, thereby reducing the burrs generated at the cutting edge of the electrode sheet. At the same time, it allows the electrode sheet to slide down under its own weight after cutting and be discharged from the receiving plate 22, so as to facilitate the next cutting cycle of the receiving plate 22.
[0072] In some embodiments, please refer to Figure 3 The value of A ranges from 120° to 130°.
[0073] Setting A within the aforementioned range increases the inclination of the first plate 221 (compared to 160°). Under the influence of gravity, the contact area between the excess material and the plate increases, enhancing friction and making it easier for the excess material to adhere smoothly to the surface of the first plate 221. Furthermore, an inclination angle of 120°-130° stabilizes the excess material, reducing its vibration and resulting in a smoother cutting edge and fewer burrs.
[0074] In some embodiments, please refer to Figure 1 and Figure 2 The receiving plate 22 also includes a second plate 222, which is located on top of the first plate 221 and is set at an obtuse angle to the first plate 221.
[0075] The connection methods between the second plate 222 and the first plate 221 include, but are not limited to, welding, bolting, or riveting.
[0076] In one example, the first plate 221 and the second plate 222 are integrally formed. Alternatively, the first plate 221 and the second plate 222 can be integrally formed by stamping or sheet metal bending.
[0077] The first plate 221 and the second plate 222 are set at an obtuse angle. On the one hand, this can make the receiving plate 22 have higher strength. After the receiving plate 22 is installed in the main body 21, A can be kept within the set angle range to ensure the cutting effect. On the other hand, it can make the first plate 221 avoid the electrode to reduce the impact on the electrode during the cutting process.
[0078] In some embodiments, please refer to Figure 1 and Figure 2 The second plate 222 is parallel to the height direction Z of the anti-shake device 20.
[0079] Therefore, the second plate 222 can be used as a positioning reference, and the angle between the second plate 222 and the first plate 221 can be maintained at A. This ensures that the angle between the first plate 221 and the height direction Z of the anti-vibration device 20 is also A, which facilitates manufacturing and installation. In addition, it can reduce the accumulation of excess material on the second plate 222, so that the receiving plate 22 can cyclically support the excess material.
[0080] In some embodiments, please refer to Figure 2 The receiving plate 22 includes a retaining edge 223. The first plate 221 is connected to the retaining edge 223 on both sides along the first direction X, and / or the second plate 222 is connected to the retaining edge 223 on both sides along the first direction X.
[0081] The first direction X is perpendicular to the height direction Z of the second plate 222 and the anti-shake device 20.
[0082] When the first plate 221 is connected to two sides of the first direction X with flanges 223 respectively, the connection method between the first plate 221 and the flanges 223 includes, but is not limited to, welding, bonding or snap-fitting. The flanges 223 are also integrally formed with the first plate 221.
[0083] When the second plate 222 is connected to the two sides of the first direction X with flanges 223 respectively, the connection method between the second plate 222 and the flanges 223 includes, but is not limited to, welding, bonding or snap-fitting. The flanges 223 are also integrally formed with the second plate 222.
[0084] The setting of the retaining edge 223 serves to guide the scrap material so that it can be sent out from the discharge end of the receiving plate 22, preventing the scrap material from accumulating and blocking on the receiving plate 22, so that the cutting device 10 can produce continuously.
[0085] In some embodiments, please refer to Figure 2 The first plate 221 is provided with adsorption holes 2211, which are configured to adsorb residual material in a negative pressure manner.
[0086] The adsorption pores 2211 can be, but are not limited to, circular, square, rectangular, elliptical or other irregular shapes.
[0087] The adsorption hole 2211 is configured to adsorb residual material using negative pressure: negative pressure is introduced into the adsorption hole 2211, allowing the residual material to adhere to the first plate 221. The residual material can be fixed relative to the first plate 221, or it can slide downwards on the first plate 221 under its own weight. A negative pressure adsorption pipeline can be connected to the adsorption hole 2211 to fix the residual material to the first plate 221. After the residual material is cut, the negative pressure in the adsorption pipeline is released, allowing the residual material to move downwards under its own weight. Alternatively, the negative pressure adsorption pipeline can be used to adsorb the residual material, causing the adsorption hole 2211 to generate a small adsorption force, allowing the residual material to move downwards under its own weight. A negative pressure recovery pipeline 60 can also be installed below the cutting device 10. The negative pressure of the negative pressure recovery pipeline 60 can be used to generate an adsorption force on the residual material through the adsorption hole 2211, causing the residual material to adhere to the first plate 221 and slowly slide downwards, thus recovering the residual material.
[0088] This allows the scrap material to be flatly attached to the upper surface of the first plate 221, so that the first plate 221 provides greater support for the scrap material, reduces the vibration of the scrap material during the cutting process, thereby reducing the burrs generated at the cutting edge and improving the cutting quality of the electrode sheet.
[0089] In some embodiments, please refer to Figure 2 The first plate 221 is provided with a plurality of adsorption holes 2211, which are spaced apart on the first plate 221.
[0090] In one example, multiple adsorption pores 2211 may be arranged in a rectangular array on the first plate 221. Specifically, the spacing between two adjacent adsorption pores 2211 may be, but is not limited to, 0.5 cm, 1 cm, 1.5 cm or 2 cm.
[0091] Multiple adsorption holes 2211 can further enhance the support force of the first plate 221 on the scrap material, so that the scrap material can be more evenly attached to the first plate 221, thereby reducing the burrs generated during the cutting process.
[0092] In some embodiments, the area of the adsorption pore 2211 ranges from 0.79 cm² to 7 cm².
[0093] In one example, the adsorption pore 2211 is a circular pore with a diameter between 1 cm and 3 cm.
[0094] The area of the adsorption hole 2211 is set within the above range, which can reduce the possibility of residual material clogging the adsorption hole 2211 and passing through the adsorption hole 2211, so that the residual material can better adhere to the first plate 221.
[0095] In some embodiments, please refer to Figure 1 and Figure 4 The main body 21 includes a conveyor belt conveying mechanism, which includes a conveyor belt 211. The conveyor belt 211 is configured to abut against the workpiece 50 to be cut, and the cutting device 10 is configured to cut the workpiece 50 on the surface of the conveyor belt 211.
[0096] In a specific example, please refer to Figure 1 and Figure 4 The conveyor belt conveying mechanism includes a frame 214, a motor (not shown in the figure), a first drive roller 212, and a second drive roller 213. The first drive roller 212 and the second drive roller 213 are rotatably connected to the frame 214. Along the height direction Z of the anti-vibration device 20, the first drive roller 212 and the second drive roller 213 are spaced apart and connected via a conveyor belt 211. One of the first drive roller 212 and the second drive roller 213 can be driven by a motor to achieve approximately synchronous movement with the workpiece 50 to be cut via the conveyor belt 211. The conveying direction of the conveyor belt 211 can be the same as or intersect with the height direction Z of the anti-vibration device 20, meaning the conveyor belt 211 can be inclined from top to bottom to form a ramp for conveying the workpiece 50 to be cut.
[0097] The conveyor belt 211 transports the workpiece 50 to be cut, providing support to reduce vibration during cutting and resulting in a smoother cut edge. It also ensures that the workpiece 50 and the conveyor belt 211 move synchronously, minimizing damage to the electrode sheet caused by relative slippage. In another example, the body 21 can be a roller conveyor.
[0098] In some embodiments, please refer to Figure 1 The conveying direction of the conveyor belt 211 is the height direction Z of the anti-vibration device 20.
[0099] This allows the cut scraps to fall directly onto the receiving plate 22 under their own weight, making them easy to recycle.
[0100] In some embodiments, the cutting system further includes a winding roller 40 located on the side of the anti-vibration device 20 opposite to the cutting device 10, and the winding roller 40 is configured to wind up the portion remaining after the workpiece 50 is cut.
[0101] The winding roller 40 is rotatably mounted on the frame. The winding roller 40 can be driven by a winding motor to realize the automatic winding of the workpiece 50 to be cut, thereby saving manpower.
[0102] Therefore, it is convenient to perform a winding operation on the cut workpiece 50.
[0103] In some embodiments, please refer to Figure 1 The cutting system also includes a guide roller 30, which is located above the anti-vibration device 20. The guide roller 30 is configured to guide the received workpiece 50 to be cut to the feed end of the anti-vibration device 20. The guide roller 30 and the winding roller 40 together provide tension to the workpiece 50 so that part of the workpiece 50 can come into contact with the anti-vibration device 20.
[0104] The guide roller 30 is rotatably mounted on the frame. The frame rotatably connected to the guide roller 30 and the frame rotatably connected to the winding roller 40 can be the same frame or different frames.
[0105] The combined tension of the guide roller 30 and the winding roller 40 keeps the workpiece 50 taut and allows it to adhere to the body 21. When conveying and cutting are performed simultaneously, the vibration of the workpiece 50 can be reduced, making the cutting edge smoother and reducing the generation of burrs.
[0106] In some embodiments, please refer to Figure 1 The cutting system also includes a negative pressure recovery pipe 60, which is located below the receiving plate 22 and is configured to suck up the scrap material in a negative pressure manner.
[0107] Optionally, the negative pressure recovery pipeline 60 can be connected to a recovery bin, which can generate negative pressure through a vacuum pump or a blower to suck the residual material into the recovery bin for storage for subsequent processing.
[0108] The negative pressure generated by the negative pressure recovery pipe 60 draws the cut-off residue into the negative pressure recovery pipe 60 for subsequent processing.
[0109] For ease of explanation, please refer to the following embodiments. Figures 1-3 The following description will be based on a battery production system according to some embodiments of this application.
[0110] The battery production system includes the cutting system described in the above embodiment, and the part to be cut 50 is an electrode sheet.
[0111] Since the battery production system includes all the technical features of the aforementioned cutting system, and its effect is the same as described above, it will not be repeated here.
[0112] In one alternative embodiment of the battery production system, please refer to Figures 1-3The cutting system includes a cutting device 10, an anti-vibration device 20, and a negative pressure recovery pipeline 60. The anti-vibration device 20 includes a body 21 and a receiving plate 22. The cutting device 10 is located on one side of the body 21 and is configured to cut the workpiece 50 to be cut on the surface of the body 21. The body 21 is configured to provide support to the workpiece 50, and the receiving plate 22 is connected to the bottom of the body 21. The receiving plate 22 includes a first plate 221, a second plate 222, and a retaining edge 223. The first plate 221 is inclined downwards and is used to receive and guide the remaining material from the workpiece 50 cut by the cutting device 10. The first plate 221 and the second plate 222 are set at an obtuse angle, with the included angle ranging from 120° to 160°. The first plate 221 is parallel to the height direction Z of the cutting device 10. Multiple circular adsorption holes 2211 can be provided on the first plate 221. The diameter of the circular adsorption holes 2211 can range from 1cm to 3cm, and the distance between two adjacent adsorption holes 2211 can be 1cm. The negative pressure recovery pipeline 60 is configured to introduce negative pressure so that the multiple adsorption holes 2211 generate an adsorption force on the scrap material, and allow the scrap material to slide downward relative to the first plate 221 to recover the cut scrap material.
[0113] The negative pressure generated by the negative pressure recovery pipeline 60 causes the adsorption holes 2211 to generate adsorption force and the first plate 221 to be tilted downward, which can increase the support force of the residual material so that the residual material can be flatly attached to the first plate 221, reduce the vibration generated during the electrode cutting process, make the cutting edge of the electrode flatter, and reduce the burrs on the cutting edge, so as to improve the cutting quality.
