Description

Technical Field

[0001] This utility model relates to the field of lithium battery production equipment technology, and in particular to a dust removal device for a slitting machine in a lithium battery production line. Background Technology

[0002] In lithium battery production, the electrode slitting machine is one of the key pieces of equipment, used to cut wide electrode materials into narrow strips of the required width for further processing into lithium battery cells. During the electrode slitting process, the foil is driven by the machine's steel rollers. The carbon black in the foil's coating area comes into contact with the rollers, causing carbon black to detach and form micron-sized dust particles with a diameter of 1mm-2mm. Over time, these particles accumulate and thicken, negatively impacting the quality of the foil. If not removed promptly, these micron-sized dust particles will adhere to the surface of the machine's steel rollers, leading to decreased slitting accuracy, increased equipment wear, and even affecting the consistency and other critical performance characteristics of the produced lithium batteries. Therefore, the dust removal device, as a core component of the slitting machine, directly affects the production efficiency and product quality of the lithium battery production line.

[0003] To address this issue, Chinese patent document CN222288189U discloses a novel dust-adhesion device. This device mounts its housing onto an optical inspection instrument. When a PCB board is transported inside the instrument, it passes over a dust-adhesion roller, which adheres to the dust on the PCB. The dust is then transferred to a dust-adhesion paper roll through contact with the roller, thus removing the dust from the PCB. However, while this patented dust-adhesion device can remove dust from PCBs, it suffers from several drawbacks in practical use. These include a large space requirement, low frame strength, and the inability of the dust-adhesion roller to adaptively adjust to the machine's steel rollers. It cannot efficiently and promptly remove dust, and its overall structural stability is poor. Significant vibration occurs when the rotation speed exceeds 100 m / min, affecting production efficiency and product quality, making it unsuitable for dust removal during electrode slitting. Furthermore, replacing or removing the dust-adhesion paper roll requires disassembling the mounting base, which is inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide a dust removal device for a slitting machine in a lithium battery production line. By improving the overall structural design and coordinating the various parts, the space occupied by the dust removal device is reduced, the frame strength is enhanced, and the gap and surface contact pressure between the dust-adhesive paper roll and the dust-adhesive roller and the steel roller of the machine can be adaptively adjusted, so as to remove dust in a timely and efficient manner, thereby solving the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A dust removal device for a slitting machine in a lithium battery production line is characterized by comprising an integral bottom support, a fixed seat, a dust-adhesive roller, a bearing, a dust-adhesive paper roll, an elastic clamp, a first adaptive control component, a second adaptive control component, and a machine base steel roller; the upper surfaces of the left and right sections of the integral bottom support are symmetrically provided with upwardly extending fixed seats, and the dust-adhesive roller, the dust-adhesive paper roll, the first adaptive control component, and the second adaptive control component are installed inside the fixed seats; wherein, the first adaptive control component includes a first cylinder on the left, a second cylinder on the right, and a first sliding seat, and the second adaptive control component includes a third cylinder on the left, a fourth cylinder on the right, and a second sliding seat; the first and second adaptive control components together adjust the gap between the dust-adhesive roller and the dust-adhesive paper roll, pushing the dust-adhesive roller to fit tightly against the machine base steel roller and the dust-adhesive paper roll to fit tightly against the dust-adhesive roller.

[0006] The integrated bottom support is a long strip structure made of stainless steel, which enhances the overall rigidity and strength of the frame.

[0007] The axes of the sticky roller, the sticky paper roll, and the machine steel roller are arranged horizontally in the vertical direction, and the sticky roller is located in the middle position between the sticky paper roll and the machine steel roller.

[0008] The fixed base consists of two units, which are arranged symmetrically on the left and right sides of the integral bottom bracket. Each of the two fixed bases has a detachable first sliding base and a second sliding base on its inner side. Both the fixed base and the first sliding base have a set of slide rails on their inner end faces, and the two sets of slide rails are parallel in the vertical direction.

[0009] The first sliding seat is mounted on the inner end face of the fixed seat via a first slide rail, and the second sliding seat is mounted on the inner end face of the first sliding seat via a second slide rail.

[0010] Each of the above cylinders includes a cylinder body and a telescopic rod. The cylinder bodies of the first cylinder and the second cylinder are fixed on the inner end face of the fixed seat. The cylinder bodies of the third cylinder and the fourth cylinder are fixed on the inner end face of the first sliding seat. Both the first sliding seat and the second sliding seat are provided with a set of L-shaped push-pull plates on their sides, and each set of L-shaped push-pull plates is arranged opposite each other (symmetrically from left to right); each set of L-shaped push-pull plates is provided with openings at both ends, one end of the L-shaped push-pull plate is fixed to the side of the corresponding sliding seat through the opening, and the telescopic rod passes vertically upward through the opening to the other end of the L-shaped push-pull plate; The telescopic rod has a threaded section at its tail, and two nuts (upper and lower nuts) are also provided on the threaded section of the telescopic rod; the other end of the L-shaped push-pull plate is placed between the two nuts; wherein, the lower nut provides a limit, and the upper nut adjusts the position of the upper nut according to the thickness of the L-shaped push-pull plate, thereby fixing the relative position between the telescopic rod and the L-shaped push-pull plate; when the cylinder is running, the telescopic rod of each cylinder pushes and pulls the L-shaped push-pull plate, which in turn drives the sliding seat to rise and fall.

[0011] The pressure of the cylinder is adjusted by using a pressure regulating valve. The air compressibility of the cylinder itself is used to adjust the gap or pressure between the contact surfaces of the steel roller and other rollers, so as to ensure that the dust-adhesive roller can still be tightly attached to the surface of the steel roller at a high speed of 200M / min.

[0012] The two ends of the adhesive roller are connected to bearings on both sides by couplings. The bearings on both sides are installed in bearing seats on the first sliding seat. The two ends of the adhesive paper roll are clamped by the elastic clamps. Both ends of the elastic clamps are fixed to the inner end face of the second sliding seat.

[0013] One end of the elastic clamp is provided with a spring, and the elastic clamp moves in extension and retraction due to the elasticity of the spring. The other end of the elastic clamp is fixed and cannot move, and the other end is suspended in the air for attaching the hollow end face of the dust-adhesive paper roll.

[0014] When the adhesive paper roll is installed, the two end faces are clamped or released by the horizontal extension and retraction of the spring in the elastic clamp, which makes it convenient to directly and quickly install and remove the adhesive paper roll without disassembling the second sliding seat.

[0015] The dust-adhesive roller is raised by the first cylinder on the left and the second cylinder on the right, which together push the first sliding seat upward, thereby causing the dust-adhesive roller to move horizontally towards and adhere to the machine's steel roller. The dust-adhesive paper roll is raised by the third cylinder on the left and the fourth cylinder on the right, which together push the second sliding seat upward, thereby causing the dust-adhesive paper roll to move towards and adhere to the dust-adhesive roller. This ensures reliable contact between the machine's steel roller, the dust-adhesive roller, and the surface of the dust-adhesive paper roll, maintaining a certain surface contact pressure, so as to remove dust in a timely and efficient manner and ensure product quality. The machine tool steel roller, the adhesive paper roll, and the adhesive roller are linked together. The machine tool steel roller drives the adhesive roller to rotate, which in turn drives the adhesive paper roll to rotate, quickly transferring dust from the machine tool steel roller to the adhesive paper.

[0016] The viscosity of the outer surface of the dust-adhesive roller is changed from the medium viscosity surface in the prior art to a high viscosity surface, so that its viscosity is appropriately enhanced, the adhesion of dust is better, and it can quickly capture suspended dust and improve dust removal efficiency.

[0017] The bearings are angular contact bearings and are arranged in groups. Each group includes a first bearing connecting to the left coupling of the sticky roller and a second bearing connecting to the right coupling of the sticky roller. Using angular contact bearings instead of traditional deep groove ball bearings, and employing bearing end caps for the first and second bearings to limit axial displacement, ensures that the bearings and shaft system maintain a stable position during high-speed operation, thereby guaranteeing the stability and reliability of the overall system at high speeds. The first and second bearings work together as a group, which improves the service life of the bearings.

[0018] In summary, compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through multifaceted structural improvements and design, simplifies the overall structure and coordinates the various parts, resulting in a compact overall structure that significantly reduces the space occupied by the dust removal device. It can be installed inside the original slitting machine, allowing for high-speed operation and reducing overall energy consumption by over 30%. By incorporating a first and second adaptive control component, the gap and surface contact pressure between the dust-adhesive paper roll / roll and the machine's steel rollers can be adaptively adjusted, enabling timely and efficient dust removal and ensuring product quality. Testing shows that this utility model, operating at a high speed of 200 m / min, can achieve rapid removal and recovery of micron-level dust from the machine's steel roller surface through cylinder adaptive control of the gap and contact pressure between rollers. The total removal rate of micron-level dust is greater than 90%, achieving efficient dust transfer from the machine's steel rollers to the dust-adhesive paper roll, extending the lifespan of the machine's steel rollers, and improving the quality of the electrode sheet products.

[0019] 2. This utility model also improves the stability of the overall structure. On the one hand, the integral bottom support is made of high-strength stainless steel (integrated stamping or welding) to enhance the mechanical strength of the frame. On the other hand, it adopts a left-right symmetrical structural design, with the first and second adaptive control components operating synchronously. The bearings are designed in groups to avoid vibration of each roller when rotating at high speed, thereby improving production efficiency and product quality.

[0020] 3. By setting up an elastic clamp and a spring, when replacing or removing the adhesive paper roll, the elastic displacement of the spring in the elastic clamp can loosen or clamp the two ends of the adhesive paper roll, realizing the quick assembly and disassembly of the old and new paper rolls without disassembling the fixing base, significantly shortening maintenance time and improving the convenience of operation.

[0021] 4. By improving the bearing and its installation structure, this utility model can effectively extend the service life of the entire device, especially the service life of the steel roller of the machine platform by more than 2 times, as tested. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Example See Figures 1-6 The dust removal device for the slitting machine of the lithium battery production line provided by this utility model is specifically installed on the lithium battery production line and works in conjunction with the electrode slitting machine to quickly adsorb the micron-level dust generated during the slitting process, so as to avoid affecting the quality of the electrode and the life of the steel roller.

[0026] See Figure 1 The dust removal device of the slitting machine in the lithium battery production line has two symmetrically arranged fixed seats 6 extending upward on the upper surfaces of the left and right sections of the integral bottom support 7. The two fixed seats 6 are equipped with a dust-adhesive roller 2, a dust-adhesive paper roll 3, a first adaptive control component 4, and a second adaptive control component 5. The two ends of the dust-adhesive roller 2 are installed inside the first adaptive control component 4 through bearings 21 and are limited by bearing end caps 22. The two ends of the dust-adhesive paper roll 3 are clamped and installed inside the second adaptive control component 5 through elastic clamps 31. The first adaptive control component 4 pushes the dust-adhesive roller 2 closer to and adheres to the side of the machine's steel roller 1 facing each other (or separates them in the opposite direction). The second adaptive control component 5 pushes the dust-adhesive paper roll 3 closer to and adheres to the side of the dust-adhesive roller 2 facing each other (or separates them in the opposite direction). It can maintain a stable surface contact pressure in the adhered state, which can cooperate with high-speed operation and ensure the dust removal effect.

[0027] When the strength of the integral bottom support 7 is insufficient, the high-speed rotation of each roller will cause obvious vibration. This embodiment focuses on strengthening the frame strength of the integral bottom support 7, which can quickly transfer the energy of the vibration generated by the rotation of each roller to the slitting machine, thereby avoiding the vibration phenomenon. The integral bottom support 7 is made of stainless steel, which enhances the overall rigidity and frame strength, so that there will be no obvious vibration during high-speed rotation, and the maximum operating speed can reach 200M / min, which also increases the service life of the integral bottom support 7 itself.

[0028] In this embodiment, two upwardly extending fixed seats 6 are symmetrically provided on the upper surfaces of the left and right sections of the integral bottom bracket 7. The two fixed seats 6 are equipped with a dust roller 2, a dust paper roll 3, a first adaptive control component 4, and a second adaptive control component 5. The first adaptive control component 4 includes a first cylinder 41 on the left, a second cylinder 42 on the right, and a first sliding seat 43. The second adaptive control component 5 includes a third cylinder 51 on the left, a fourth cylinder 52 on the right, and a second sliding seat 53. A detachable first sliding seat 43 and a second sliding seat 53 are respectively provided on the inner side of the two fixed seats 6. A set of slide rails 8 is provided on the inner end face of both the fixed seats and the first sliding seat 43. The two sets of slide rails 8 are parallel in the vertical direction. Each sliding seat and slide rail 8 is used to drive the relative movement of the components set on it.

[0029] The first sliding seat 43 is mounted on the inner end face of the fixed seat 6 via the first slide rail 81, and the second sliding seat 53 is mounted on the inner end face of the first sliding seat 43 via the second slide rail 82. Each cylinder includes a cylinder body and a telescopic rod. The cylinder bodies of the first cylinder 41 and the second cylinder 42 are both fixed on the inner end face of the fixed seat 6, and the cylinder bodies of the third cylinder 51 and the fourth cylinder 52 are both fixed on the inner end face of the first sliding seat 43. A set of L-shaped push-pull plates 9 are provided on the sides of both the first sliding seat 43 and the second sliding seat 53. Each set of L-shaped push-pull plates 9 is arranged opposite each other (symmetrically). Openings are provided at both ends of the L-shaped push-pull plates 9. One end of the L-shaped push-pull plate 9 is fixed to the corresponding sliding seat side through the opening, and the telescopic rod passes vertically upward through the opening to the other end of the L-shaped push-pull plate 9. A threaded section is provided at the tail of the telescopic rod, and two screws are also provided on this threaded section. The other end of the L-shaped push-pull plate 9 is placed between the two nuts (upper and lower nuts). The lower nut limits the position, and the upper nut adjusts the position of the upper nut according to the thickness of the L-shaped push-pull plate 9, fixing the relative position between the telescopic rod and the L-shaped push-pull plate 9. When the cylinder is running, the telescopic rod of each cylinder pushes and pulls the L-shaped push-pull plate 9, which in turn drives the sliding seat to rise and fall. The cylinder pressure is adjusted by the pressure regulating valve, and the air compressibility of the cylinder itself is used to adjust the gap or pressure between the contact surface of the machine tool steel roller 1 and other rollers, so as to ensure that the dust-adhesive roller 2 can still reliably adhere to the surface of the machine tool steel roller 1 and peel off the dust on its surface even when running at a high speed of 200M / min.

[0030] The axes of the sticky roller 2, the sticky paper roll 3, and the machine steel roller 1 are arranged horizontally in the vertical direction, with the sticky roller 2 located in the middle between the sticky paper roll 3 and the machine steel roller 1. When the sticky roller 2 cannot be tightly attached to the machine steel roller 1, it will cause the sticky roller 2 to be unable to peel off the micron-sized dust on the surface of the machine steel roller 1 in time and then quickly transfer it to the sticky paper roll 3. This will cause the dust to be deposited on the surface of the machine steel roller 1, affecting the product quality and the life of the machine steel roller 1. The product often fails to meet the quality requirements.

[0031] In this embodiment, the cylinders (controlled by PLC) of the first adaptive control component 4 and the second adaptive control component 5 are used to adjust the parallel positions of the dust-adhesive roller 2 and the dust-adhesive paper roll 3, ensuring that the surfaces of the dust-adhesive roller 2 and the machine steel roller 1, and the dust-adhesive paper roll 3 and the dust-adhesive roller 2 are always in close contact during operation, preventing separation due to vibration. This avoids the situation where the dust-adhesive roller 2 fails to peel off the micron-sized dust from the machine steel roller 1 and transfer it to the dust-adhesive paper roll 3. When the dust-adhesive roller 2 extends upwards parallel to the telescopic rods of the first cylinder 41 on the left and the second cylinder 42 on the right, they jointly push the first sliding seat 43 upwards. The sticky roller 2 is driven to adhere to the surface of the machine tool steel roller 1. When the telescopic rods of the third cylinder 51 on the left and the fourth cylinder 52 on the right extend upward in parallel, they jointly push the second sliding seat 53 to rise, thereby driving the sticky paper roll 3 to adhere to the surface of the sticky roller 2. The sticky paper roll 3, in the mutually adhered state, forms a passive linkage with the sticky roller 2 and the machine tool steel roller 1. The machine tool steel roller 1 drives the sticky roller 2 to rotate, which in turn drives the sticky paper roll 3 to rotate synchronously. The sticky roller 2 peels off the micron-level dust on the surface of the machine tool steel roller 1 and transfers it to the sticky paper roll 3, achieving the technical effect of quickly and efficiently transferring the dust from the machine tool steel roller 1 to the sticky paper roll 3.

[0032] In this embodiment, the two end faces of the adhesive roller 2 are connected by a coupling to the first bearing 211 on the left and the second bearing 212 on the right. The bearings 21 on both sides are respectively installed in the bearing seats on the first sliding seat 43. The first bearing 211 and the second bearing 212 are both limited by the bearing end cover 22 to restrict the axial displacement of the bearings 21, ensuring that the bearings 21 and the shaft system maintain the correct position during equipment operation, thereby ensuring the stability and reliability of the mechanical system. The bearings 21 are replaced with angular contact bearings 21 instead of the commonly used deep groove ball bearings 21. Compared with deep groove ball bearings 21, angular contact bearings 21 have significant advantages in high-speed and high-precision equipment due to their axial load capacity, high-speed stability, high rigidity and long service life. In this embodiment, on the one hand, angular contact bearings 21 are used, and on the other hand, the installation method of bearings 21 is changed. The first bearing 211 and the second bearing 212 are set as a combination and operate in coordination with each other, which improves the service life of bearings 21.

[0033] The lower the hardness value of the adhesive roller, the softer its material and the higher its viscosity. When the hardness value HA is between 40 and 45, its viscosity is medium viscosity level; while when the hardness value HA is between 35 and 40, it is high viscosity level. In this embodiment, the viscosity of the outer surface of the adhesive roller 2 is further changed from medium viscosity surface to high viscosity surface, so as to enhance the viscosity, better adsorption, easier adsorption of suspended micron-sized dust, improve dust removal effect, and better surface adhesion with other rollers.

[0034] The adhesive paper roll 3 is held at both ends by elastic clamps 31, and both ends of the elastic clamps 31 are fixed to the inner end face of the second sliding seat 53. A spring 32 is provided at one end of the elastic clamp 31, and the elastic clamp 31 can extend and retract through the spring 32. The other end is fixed and cannot move. The elastic extension and retraction of the spring 32 can achieve the clamping or loosening of the adhesive paper roll 3, and the adhesive paper roll 3 can be quickly assembled and disassembled without disassembling the second sliding seat 53.

[0035] In practical use, this utility model includes the following steps: 1. Install this utility model inside the machine base of the slitting machine. First, connect the two ends of the sticky roller 2 to the bearings 21 on both sides through the coupling. The bearings 21 on both sides are respectively installed in the bearing seats on the first sliding seat 43. The first sliding seat 43 is installed on the inner end face of the fixed seat 6 through the first slide rail 81. Then, fix both ends of the elastic clamp 31 on the inner end face of the second sliding seat 53. The two ends of the sticky paper roll 3 are clamped by the elastic clamp 31 on the inner side of the second sliding seat 53. The second sliding seat 53 is installed on the inner end face of the first sliding seat 43 through the second slide rail 82. A set of cylinders is installed on the inner end face of the fixed seat 6 and the inner end face of the first sliding seat 43. A set of L-shaped push-pull plates 9 are installed on the side of the first sliding seat 43 and the second sliding seat 53. Each set of cylinders corresponds to a set of L-shaped push-pull plates 9. The telescopic rod of each cylinder passes through the L-shaped push-pull plate 9 and is fixed by a nut. The first cylinder 41, the second cylinder 42 and the first sliding seat 43 constitute the first adaptive control component 4. The third cylinder 51, the fourth cylinder 52 and the second sliding seat 53 constitute the second adaptive control component 5. After assembly, the machine is started to produce, so that the electrode sheet passes through the steel roller 1 of the machine table. 2. The first adaptive adjustment component 4 is controlled by PLC, and the first cylinder 41 and the second cylinder 42 extend upward to push the first sliding seat 43 to rise, thereby driving the dust-adhesive roller 2 to adhere to the steel roller 1 of the machine. Then, the second adaptive adjustment component 5 is controlled by PLC, and the third cylinder 51 and the fourth cylinder 52 extend upward to push the second sliding seat 53 to rise. In the working state, the dust-adhesive paper roll 3 can be continuously driven to adhere to the dust-adhesive roller 2. 3. The PLC controls the slitting machine to start slitting the electrode strip. During the slitting process, the electrode material continuously passes through the machine's steel roller 1. A large amount of micron-sized dust (shed positive or negative electrode particles) is generated near the surface of the steel roller 1. If not removed in time, it will adhere to the surface of the steel roller 1. At this time, the steel roller 1 drives the dust-adhesive roller 2 to rotate, which in turn drives the dust-adhesive paper roll 3 to rotate synchronously. The dust-adhesive roller 2 peels off the micron-sized dust on the steel roller 1 and transfers it to the dust-adhesive paper roll 3. After passing through a certain length of electrode, the dust continues to adhere. On the adhesive paper roll 3, the surface viscosity of the adhesive paper roll 3 will decrease rapidly. After the viscosity of the adhesive paper roll 3 decreases, tear off a section of adhesive paper at the current position of the adhesive paper roll 3 to restore the surface tackiness of the adhesive paper roll 3. It should be noted that the adhesive paper roll 3 is made of layers of non-continuous adhesive paper rolled up and bonded to the take-up drum. When the outermost layer of adhesive paper is covered with dust, the robot or similar mechanism will tear off the outermost layer of adhesive paper, and the second layer of adhesive paper can be used. This process continues until all the adhesive paper is torn off, at which point the entire adhesive paper roll 3 is replaced with a new one. 4. When replacing the entire adhesive paper roll 3, first stop the machine and control the third cylinder 51 and the fourth cylinder 52 of the second adaptive control component 5 to retract downwards, pull the second sliding seat 53 down, so that the adhesive paper roll 3 is separated from the adhesive roller 2, and the spring 32 in the telescopic elastic clamp 31 is compressed, so that the adhesive paper roll 3 is fixed and cannot move at the telescopic elastic clamp 31 and is about to fall off, remove the adhesive paper roll 3, and then replace it with a new paper roll. 5. Repeat step 2 above, so that the dust-adhesive roller 2 is attached to the steel roller 1 of the machine table and the dust-adhesive paper roll 3 is attached to the dust-adhesive roller 2. Then repeat steps 3 and 4 until all the cutting operations of the electrode strip or roll are completed.

[0036] The prototype of the dust removal device for the slitting machine of the lithium battery production line provided in this embodiment has been installed on the lithium battery production line and tested under confidential conditions. It has been proven that it can work closely with the electrode slitting machine to quickly adsorb various dusts generated during the slitting process, improve the production quality of the electrode sheets and the service life of the machine's steel rollers, and has low power consumption and good structural stability.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
