[0002] In the production process of energy storage media, its structure is mainly composed of several key parts: positive electrode, negative electrode and diaphragm. In order to achieve specific circuit connection and other functions, it is necessary to cut the tabs at both ends of the positive and negative electrodes. The laser cutting machine currently used removes some dust generated during the cutting process by suction when cutting the tabs. However, this suction method has certain disadvantages. During the suction process, airflow is generated, and the effect of the airflow causes the material to shake. The shaking of the material will directly lead to the problem of insufficient precision when cutting the tabs. This will have an adverse effect on the production quality and performance of the energy storage medium, and may affect the subsequent assembly and the overall use effect and safety.

After two abutment plates approach each other, they abut against the material, and a cutting space is formed between two adjacent abutment plates located on the same side.

[0005] Optionally, it also includes: Slide rails, which are used in pairs. The slide rails used in pairs are both arranged in the laser cutting machine body, located on the upper and lower sides of the material; The slide bars are in a plurality of numbers, one end of each of the slide bars is slidably disposed on the slide rail, the slide bars are evenly spaced, and the abutment plate is slidably disposed on the slide rail through the other end of the slide bars.

[0006] Optionally, the slide rail has a slide groove, the slide rod has a ball head at one end close to the slide rail, and the ball head is slidably arranged in the slide groove, and further comprises: The balls are in a certain number, and the balls are rolled in the slide grooves, located between adjacent ball heads, and abut against the ball heads. After the balls roll, they drive the ball heads to slide synchronously in the slide rails.

[0007] Optionally, the slide rail further has a guide groove, the slide rod has a guide portion, and the guide portion is slidably disposed in the guide groove.

[0008] Optionally, the slide rail further has teeth, and further comprises: A first driving member, wherein the first driving member is arranged on any of the sliding rods, and an output end of the first driving member is meshed with the teeth.

[0012] Optionally, it also includes: A push rod, one end of which is vertically slidably arranged on the side of the slide rail away from the slide groove, and after the push rod slides, one end of the push rod abuts against the ball, and the other end of the push rod has a pressing portion; A second elastic member, two ends of which are respectively in contact with the slide rail and the pressing portion, and are used to provide the pressing portion with a side away from the slide rail.

[0014] The working principle and beneficial effects of the present invention are: In the present invention, in order to solve the problem of insufficient cutting accuracy caused by material shaking during cutting of energy storage media in the related art, a laser cutting device for processing energy storage media is designed. The laser cutting machine has the function of generating laser and cutting materials using laser beams. The materials are transported in the device in a horizontal direction.

[0015] The abutment plate is set to better assist the cutting process and prevent the material from shaking during cutting. There are multiple abutment plates, which are located above and below the material. In actual operation, these abutment plates move cyclically relative to the laser cutting machine body. And they move at the same speed as the material. When the two abutment plates on the same side approach each other, they will tightly abut the material.

The laser beam accurately cuts the electrode sheet in these small spaces, cutting it into the required shape and size.

[0017] The advantage is that the abutment plate moves and abuts with the material at the same speed, which can effectively fix the position of the material during the cutting process and prevent the cutting position from shifting due to factors such as movement or vibration of the material, thereby greatly improving the accuracy of laser cutting, ensuring that the size of the energy storage medium product after cutting meets the requirements, and improving product quality. Through the cyclic movement of multiple abutment plates and the abutment with the material, a relatively stable working environment is provided for laser cutting. During the cutting process, the material can remain in a stable state, reducing the cutting error caused by external interference, making the cutting process more stable and reliable, and improving production efficiency and product consistency.

DETAILED DESCRIPTION

In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0023] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0025] Reference Figure 1 to Figure 8 , which is the first embodiment of the present invention, proposes a laser cutting device for processing an electric power storage medium, including a laser cutting machine body 1, the laser cutting machine body 1 is used to cut a material 2, and the conveying direction of the material 2 is horizontal; there are multiple abutment plates 4, and the multiple abutment plates 4 are respectively located above and in the direction of the material 2, and the abutment plates 4 are arranged to move cyclically relative to the laser cutting machine body 1, and the abutment plates 4 move at the same speed as the material 2. After the two abutment plates 4 approach each other, they abut against the material 2, and a cutting space is formed between the two adjacent abutment plates 4 located on the same side.

[0026] In this embodiment, in order to solve the problem in the related art that the material 2 shakes when the energy storage medium is cut, resulting in insufficient cutting accuracy, a laser cutting device for processing the energy storage medium is designed. The laser cutting machine has the function of generating laser and using the laser beam to cut the material 2. The material 2 is transported in the device in a horizontal direction.

[0027] The abutment plate 4 is provided to better assist the cutting process and prevent the material 2 from shaking during cutting. There are multiple abutment plates 4, which are respectively located above and below the material 2. In actual operation, these abutment plates 4 move cyclically relative to the laser cutting machine body 1. Moreover, they move at the same speed as the material 2. When the two abutment plates 4 on the same side approach each other, they will tightly abut against the material 2. At this time, a specific cutting space will be formed between the two adjacent abutment plates 4 on the same side. In this cutting space, the laser beam of the laser cutting machine body 1 can accurately cut the material 2, and the abutment effect of the abutment plate 4 can fix and position the material 2, thereby ensuring the accuracy and stability of the cutting.

[0028] For example, when the material 2 is a rectangular lithium battery electrode sheet, as the material 2 is continuously conveyed, the abutment plates 4 on the upper and lower sides approach each other and abut against the material 2 at a predetermined speed and rhythm, forming small spaces suitable for laser cutting. The laser beam accurately cuts the electrode sheet in these small spaces, cutting it into the required shape and size.

[0029] The advantage is that the abutment plate 4 moves and abuts with the material 2 at the same speed, which can effectively fix the position of the material 2 during the cutting process and prevent the material 2 from shifting in the cutting position due to factors such as movement or vibration, thereby greatly improving the accuracy of laser cutting, ensuring that the size of the energy storage medium product after cutting meets the requirements, and improving product quality. Through the cyclic movement of multiple abutment plates 4 and the abutment with the material 2, a relatively stable working environment is provided for laser cutting. During the cutting process, the material 2 can maintain a stable state, reducing the cutting error caused by external interference, making the cutting process more stable and reliable, and improving production efficiency and product consistency.

[0030] Furthermore, it also includes slide rails 5, which are used in pairs. The slide rails 5 used in pairs are all arranged in the laser cutting machine body 1, located on the upper and lower sides of the material 2; there are a number of slide rods 6, one end of a number of slide rods 6 is slidably set on the slide rails 5, and a number of slide rods 6 are evenly spaced, and the abutment plate 4 is slidably set on the slide rails 5 through the other end of the slide rod 6.

[0031] In this embodiment, a pair of slide rails 5 are respectively installed on the upper and lower sides of the material 2. These slide rails 5 are accurately fixed at appropriate positions of the laser cutting machine body 1 to provide a stable foundation for subsequent component operation.

[0032] One end of a plurality of slide bars 6 slides on the slide rail 5 and is evenly spaced. For example, according to the size of the material 2 and the cutting accuracy requirements, a slide bar 6 is arranged at a certain distance to ensure that the abutment plate 4 can evenly apply force on the surface of the material 2 and achieve stable movement. When the material 2 is being conveyed, the slide bar 6 can slide smoothly on the slide rail 5 as the material 2 moves.

[0033] The abutment plate 4 is connected to the slide bar 6 through the other end of the slide bar 6 and can move as the slide bar 6 slides on the slide rail 5. During the transmission of the material 2, the abutment plate 4 will perform corresponding movement operations driven by the slide bar 6 according to the preset program and timing. When the material 2 needs to be cut, the abutment plates 4 located on the upper and lower sides of the material 2 will approach each other under the push of the slide bar 6, and finally abut against the material 2 tightly, creating stable working conditions for laser cutting.

[0034] The advantage is that the slide rail 5 provides a solid support for the slide bar 6, ensuring that the slide bar 6 will not shake or deviate from the predetermined trajectory during movement, greatly improving the cutting accuracy. The slide bars 6 arranged at even intervals enable the abutment plate 4 to apply pressure evenly on the surface of the material 2. During the cutting process, the material 2 is subjected to uniform force, which can avoid deformation or cutting errors caused by excessive or insufficient local force. The smooth sliding of the slide bar 6 on the slide rail 5 ensures that the abutment plate 4 can quickly respond to the transmission speed of the material 2 and move at the same speed as the material 2.

[0035] Furthermore, the slide rail 5 has a slide groove 501, and the slide rod 6 has a ball head 601 at one end close to the slide rail 5. The ball head 601 is slidably set in the slide groove 501, and also includes balls 7. There are a plurality of balls 7. The plurality of balls 7 are rollingly set in the slide groove 501, located between adjacent ball heads 601, and abut against the ball heads 601. After the plurality of balls 7 roll, they drive the plurality of ball heads 601 to slide synchronously in the slide rail 5.

[0036] In this embodiment, the slide rail 5 in the device plays a key supporting and guiding role. The slide rail 5 is provided with a special slide groove 501, and the ball head 601 at one end of the slide rod 6 is cleverly embedded in the slide groove 501, so that the slide rod 6 can slide flexibly on the slide rail 5. In the slide groove 501, a number of balls 7 are evenly distributed, and these balls 7 become the key elements to achieve flexible adjustment.

[0037] When it is necessary to cut the lithium-ion battery electrode sheet, it is assumed that according to the process requirements, a smaller spacing between the abutment plates 4 is required to achieve a more refined cutting layout. At this time, the operator can achieve this by reducing the number of balls 7 between the two slide bars 6. As the number of balls 7 decreases, the relative position of the slide bar 6 in the slide groove 501 will change. Due to the change in the rolling and supporting effect of the balls 7, the spacing between adjacent abutment plates 4 becomes smaller. In this way, when cutting the electrode sheet, the abutment plate 4 can be in closer contact with the material 2, providing more accurate positioning and support for laser cutting.

[0038] When switching to a larger cutting size, a larger cutting space and a distance between the abutment plates 4 are required. The operator only needs to increase the number of balls 7 between the two slide bars 6, thereby increasing the distance between the abutment plates 4 connected thereto. This can adapt to the size of the material and the cutting requirements, creating suitable conditions for laser cutting.

[0039] During the entire adjustment process, the operation is simple and convenient. It is only necessary to easily adjust the number of balls 7 according to the cutting size of the material 2, so that the distance between two adjacent abutment plates 4 on the same slide rail 5 can be quickly and accurately changed, so that the laser cutting device can flexibly respond to the processing requirements of different types of materials 2.

[0040] The advantage is that the operation method of adjusting the number of balls 7 to change the spacing between the abutment plates 4 is simple and easy to understand, and does not require professional technicians to perform complex operations. This reduces the difficulty of equipment operation and the requirements for operator skills, and reduces equipment failures and production delays caused by operating errors. At the same time, as a relatively simple mechanical component, the balls 7 are easy to inspect, replace and maintain.

[0041] Furthermore, the slide rail 5 also has a guide groove 502 , and the slide rod 6 has a guide portion 602 , and the guide portion 602 is slidably disposed in the guide groove 502 .

[0042] In this embodiment, in the laser cutting machine body 1, the material 2 is stably transported in a predetermined transverse direction. In order to ensure the accuracy and stability of the slide bar 6 when driving the abutment plate 4 to move, a guide groove 502 is specially provided on the slide rail 5. The guide groove 502 extends along the length direction of the slide rail 5 and has a precise shape and size.

[0043] The slide bar 6 is correspondingly designed with a guide portion 602, and the shape of the guide portion 602 perfectly matches the guide groove 502. When the slide bar 6 is mounted on the slide rail 5, the guide portion 602 of the slide bar 6 is accurately slidably disposed in the guide groove 502.

[0044] The advantage is that the cooperation between the guide groove 502 and the guide portion 602 provides a clear linear motion path for the slide bar 6, avoiding the deviation and swing caused by external interference or its own structural reasons. This enables the abutment plate 4 to accurately contact the material 2 and maintain a stable position relationship, providing a high-precision positioning basis for laser cutting, and improving the processing accuracy and quality of energy storage medium products.

[0045] Furthermore, the slide rail 5 also has teeth 503 , and also includes a first driving member 8 , the first driving member 8 is arranged on any slide rod 6 , and the output end of the first driving member 8 is engaged with the teeth 503 .

[0046] In this embodiment, the slide rail 5 has a specific tooth structure 503, and the teeth 503 are evenly distributed on one side of the slide rail 5. A first driving member 8 is installed on one of the slide bars 6, and its output end is usually a gear structure or other suitable meshing component with matching teeth 503, which is tightly engaged with the teeth 503 on the slide rail 5.

[0047] When the contact plate 4 needs to be moved to a specific position of the material 2 for cutting preparation, the motor of the first driving member 8 starts to run, driving the meshing component at the output end to rotate. Due to the meshing with the teeth 503 on the slide rail 5, as the meshing component rotates, the slide bar 6 starts to slide on the slide rail 5. This sliding is precise and controllable. By adjusting the output speed and torque of the first driving member 8, the slide bar 6 can move on the slide rail 5 at different speeds. Thereby driving the contact plate 4 to accurately reach the position corresponding to the material 2, creating the best conditions for laser cutting.

[0048] The advantage is that the meshing mode of the first driving member 8 and the teeth 503 of the slide rail 5 makes the motion control of the slide bar 6 and the abutment plate 4 extremely precise. In the processing of energy storage media, the requirements for cutting accuracy are very high. Through this meshing transmission, the moving speed, position and direction of the slide bar 6 can be accurately controlled.

[0049] Furthermore, the sliding rod 6 has a sliding cylinder 603 at one end away from the sliding rail 5, and also includes a telescopic rod 9, one end of the telescopic rod 9 is slidably set on the sliding cylinder 603, and the abutment plate 4 is slidably set on the sliding rod 6 through the other end of the telescopic rod 9. After the telescopic rod 9 is extended, the abutment plate 4 abuts against the material 2; the two ends of the first elastic member 10 abut against the sliding cylinder 603 and the telescopic rod 9 respectively, so as to provide a force for the abutment plate 4 to abut against the material 2.

[0050] In this embodiment, a sliding cylinder 603 is provided at one end of the slide bar 6 away from the slide rail 5. One end of the telescopic rod 9 is designed to slide on the sliding cylinder 603. When the equipment starts to run, the telescopic rod 9 will perform telescopic movements on the sliding cylinder 603 as needed. The abutment plate 4 is connected to the telescopic rod 9 through the other end of the telescopic rod 9, thereby realizing an indirect connection with the slide bar 6. When the telescopic rod 9 is extended, the abutment plate 4 will approach the material 2 as the telescopic rod 9 moves, and finally abuts tightly against the material 2.

[0051] In this process, the two ends of the first elastic member 10 respectively contact the sliding cylinder 603 and the telescopic rod 9, generating a certain elastic force. This elastic force provides the necessary pressure for the contact plate 4 to contact the material 2, so that the contact plate 4 can be closely attached to the surface of the material 2.

[0052] The advantage is that the combined design of the telescopic rod 9 and the sliding cylinder 603 enables the abutment plate 4 to achieve flexible telescopic movement. During the laser cutting process of the material 2, different sizes of the material 2 and the cutting process require the abutment plate 4 to contact the material 2 at different times. Through the sliding of the telescopic rod 9 on the sliding cylinder 603, the abutment plate 4 can accurately adjust its position according to the actual situation to achieve timely abutment with the material 2. At the same time, the force provided by the first elastic member 10 enables the abutment plate 4 to have a certain stability when abutting with the material 2, and will not easily detach from the surface of the material 2 due to the vibration of the equipment or other external factors, thereby ensuring the close combination of the abutment plate 4 and the material 2 during the cutting process, and providing a strong guarantee for the accuracy and quality of laser cutting. During the operation of the equipment, some sudden shocks or vibrations may occur. The first elastic member 10 can play a buffering role to reduce the damage of these shocks to the equipment components.

[0053] Furthermore, it also includes a guard rail 11 , which is arranged on the slide rail 5 and abuts against a side of the slide rod 6 away from the slide rail 5 .

[0054] In this embodiment, the guard rail 11 is firmly mounted on one side of the slide rail 5. The shape and size of the guard rail 11 are well matched with the slide bar 6.

[0055] When the slide bar 6 drives the abutment plate 4 to move along with the material 2, the guard rail 11 will closely abut against the side of the slide bar 6 away from the slide rail 5 in the upper area. Assuming that at a certain moment, due to slight vibration of the equipment or the influence of other external factors, the slide bar 6 may have a tendency to deviate to one side. The guard rail 11 prevents the slide bar 6 from further deviating by abutting against the slide bar 6, so that it can continue to slide on the correct track. In this way, it is ensured that the slide bar 6 can stably drive the abutment plate 4 to accurately cooperate with the material 2, providing a reliable guarantee for laser cutting.

[0056] Furthermore, the slide rail 5 has a bead removal groove 504 for removing or adding the balls 7 and the slide rod 6 , and also includes a cover plate 12 , which is arranged in the bead removal groove 504 .

[0057] In this embodiment, when the ball bearings 7 need to be replaced or cleaned, the staff can perform the operation through the ball removal groove 504. For example, in daily maintenance, it is found that some of the ball bearings 7 are worn due to long-term use, or the distance between the abutment plates 4 needs to be adjusted. At this time, the staff can remove the ball bearings 7 through the ball removal groove 504. The design of the ball removal groove 504 makes this operation relatively simple and convenient, and the staff can easily remove the ball bearings 7 from the slide rail 5 without causing unnecessary damage to the slide rail 5 and other components.

[0058] After the replacement or cleaning of the ball bearing 7 is completed, the cover plate 12 needs to be installed in the ball removal groove 504. The size of the cover plate 12 perfectly matches the ball removal groove 504, and it can tightly cover the ball removal groove 504, ensuring that the surface of the slide rail 5 is flat, and maintaining a good sliding fit between the slide rod 6 and the slide rail 5.

[0059] Furthermore, it also includes a push rod 13, one end of which is vertically slidably arranged on the side of the slide rail 5 away from the slide groove 501. After the push rod 13 slides, one end of the push rod 13 abuts against the ball 7, and the other end of the push rod 13 has a pressing portion 1301; the two ends of the second elastic member 14 respectively abut against the slide rail 5 and the pressing portion 1301, for providing the pressing portion 1301 away from the side of the slide rail 5.

[0060] In this embodiment, a push rod 13 is provided on one side of the slide rail 5 away from the slide groove 501, and one end of the push rod 13 can slide up and down in a specific slideway or hole on the slide rail 5. After the equipment has been running for a period of time, the ball 7 may need to be inspected or adjusted. When the ball 7 needs to be replaced, the staff pushes the push rod 13 to make it slide on the slide rail 5. After the push rod 13 slides, one end of it will abut against the ball 7. Since the position and angle of the push rod 13 are carefully designed, it can accurately contact the ball 7 that needs to be operated, and exert a certain force to lift or push the ball 7 from its original position.

[0061] The other end of the push rod 13 has a pressing portion 1301, which is designed to facilitate the operation of the staff. During the operation of the push rod 13, the two ends of the second elastic member 14 are respectively in contact with the slide rail 5 and the pressing portion 1301, and the push rod 13 provides a restoring force.

[0062] When the staff presses the pressing part 1301 to make one end of the push rod 13 contact the ball 7 and operate, the second elastic member 14 will be further compressed. When the staff releases the pressing part 1301, the elastic force of the second elastic member 14 will act on the pressing part 1301, so that the push rod 13 returns to the initial position.

[0063] The combined design of the push rod 13 and the second elastic member 14 significantly enhances the maintainability of the laser cutting device. In the long-term use of the device, it is inevitable to encounter various situations where internal components need to be maintained and repaired. This easy-to-operate push rod 13 structure and the functions realized by the second elastic member 14 make it more convenient and quick for the staff to maintain key components such as the ball 7.

[0064] Furthermore, it also includes a conveying device 15, which is arranged in the laser cutting machine body 1 and is used to convey the material 2; a leveling roller 16 is rotatably arranged at one end of the conveying device 15 and abuts against the material 2.

[0065] In this embodiment, inside the laser cutting machine body 1, the conveying device 15 is located at a key position and bears the heavy responsibility of conveying the material 2. The raw material of the material 2 is placed at the starting end of the conveying device 15. As the roller rotates, the conveying device 15 drives the material 2 to move forward at a uniform speed in the lateral direction. During the conveying process, in order to ensure the flatness and position accuracy of the material 2, the leveling roller 16 plays an important role. The leveling roller 16 is rotatably arranged at one end of the conveying device 15 and is in close contact with the material 2.

[0066] When the material 2 passes through the leveling roller 16 , the leveling roller 16 will exert a certain pressure on the material 2 , driving the material 2 to be further leveled without causing damage to the material 2 .

[0067] The advantage is that the flatness of the energy storage medium material 2 during transportation can be ensured, and the unevenness such as wrinkles and bends generated during transportation of the material 2 can be effectively eliminated. This makes the surface of the material 2 flat and uniform when entering the laser cutting area, providing a stable basic condition for laser cutting, thereby ensuring the straightness of the cutting line and the accuracy of the size, and improving the quality and performance of the energy storage medium product.

[0068] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
