Description

Technical Field

[0001] The present invention belongs to the technical field of battery manufacturing, and particularly relates to a dust removal device for a battery slitting machine. Background Art

[0002] In recent years, with the strong support of the country for the new energy battery industry, the lithium-ion battery manufacturing industry has had unprecedented development. In order to improve the energy density of battery modules, more enterprises have started to produce high-energy large batteries. The scrapping of large batteries will cause more waste to enterprises, and the requirements for the quality and qualification rate of lithium-ion batteries are becoming more and more strict. Therefore, it is necessary to strengthen the control of each production process of battery production and improve the product quality and qualification rate of each production process.

[0003] As an indispensable part of the lithium-ion battery production process, the battery slitting process directly affects the performance of lithium-ion batteries by controlling its process capabilities. At present, there are still many areas worthy of improvement in this process. After the battery copper foil is slit, a lot of powder often adheres to the surface of the copper foil. If it is not cleaned regularly, it will cause the diaphragm to be punctured in the subsequent process, and ultimately may cause the battery to short-circuit and be scrapped, thereby reducing the overall qualification rate. Therefore, it is necessary to perform dust removal and cleaning on the surface of the copper foil after slitting. To achieve a better cleaning effect on copper foils of different thicknesses, a simple and adjustable dust removal device is required. Summary of the Invention

[0004] In view of the above-mentioned disadvantages of the prior art, the purpose of the present invention is to provide a simple and adjustable dust removal device that can continuously clean the surface of copper foil.

[0040] The following uses specific specific examples to illustrate the embodiments of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. The details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0041] It should be noted that the illustrations provided in the following embodiments only schematically illustrate the basic concept of the present invention. Therefore, only the components related to the present invention are shown in the illustrations, rather than being drawn according to the number, shape, and size of the components in actual implementation. The types, quantities, and proportions of the components in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0042] In the process of lithium battery production, the battery slitting process is an indispensable part. In this process, after the battery copper foil is slit, a lot of powder often adheres to the surface of the copper foil. If it is not cleaned regularly, it will cause the diaphragm to be punctured in the subsequent process, and ultimately may cause the battery to short-circuit and be scrapped, thereby reducing the overall qualification rate. Therefore, it is necessary to remove dust from the surface of the copper foil after slitting.

[0043] Please refer to Figures 1 to 4 , the present invention provides a dust removal device for a battery slitting machine, which includes a frame and a dust removal mechanism arranged on the frame. The dust removal mechanism includes a dust removal component 100 and an adjustment component 200. The dust removal component 100 can rub against the surface of the copper foil to achieve dust removal and cleaning. The adjustment component 200 is connected to the dust removal component 100 and is used to adjust the dust removal component 100 to adapt to copper foils of different thicknesses and control the cleaning effect. This device is applied to the slitting process and can effectively remove the attached powder on the surface of the slit copper foil, avoiding affecting the subsequent process; by using the adjustment component 200 for adjustment, the cleaning intensity can be controlled to achieve the best cleaning effect, and it can also adapt to the cleaning of copper foils of different thicknesses, with more flexible adjustment.

[0044] Please refer to Figures 1 to 4 , in an optional embodiment of the present invention, the dust removal component 100 is connected to the frame and includes a passing roller 110 and a rubbing roller 120. Both ends of the passing roller 110 are connected to the frame. The rubbing roller 120 is arranged on one side of the passing roller 110 and is connected to the frame through the adjustment component 200. After the copper foil is slit from the previous process, it enters between the passing roller 110 and the rubbing roller 120, and after the surface dust removal and cleaning are completed under the action of the dust removal component 100, it enters the next process. When the copper foil travels on the passing roller 110, the rubbing roller 120 is used to remove dust from its surface. A brush is also arranged on the surface of the rubbing roller 120, and the friction between the brush and the surface of the copper foil is used to achieve cleaning. In order to avoid scratches and the like on the surface during cleaning, it is necessary to control the contact pressure between it and the surface of the copper foil to protect the surface of the copper foil from damage while achieving cleaning; motors are also arranged at both ends of the rubbing roller 120. When the motors drive the rubbing roller 120 to rotate, the surface of the copper foil is cleaned through the brush, with good cleaning effect and high working efficiency.

[0045] Please refer to Figures 1 to 4, in an alternative embodiment of the present invention, the adjusting assembly 200 includes an adjusting arm 210, a quick adjustment part 220, and a fine adjustment part 230. The adjusting arm 210 is connected to the frame through a first connecting shaft 240. The quick adjustment part 220 and the fine adjustment part 230 are provided at one end of the adjusting arm 210. The other end of the adjusting arm 210 is connected to the end of the wiping roller 120, so that it can rotate around the connecting shaft under the action of the quick adjustment part 220 and the fine adjustment part 230, and then drive the wiping roller 120 at one end to move closer to or away from the passing roller 110. The quick adjustment part 220 and the fine adjustment part 230 are respectively located on both sides of the adjusting arm 210 to cooperate to limit the adjusting arm 210, and the overall structure is stable and reliable; the quick adjustment part 220 is provided on the frame, one end of which is rotatably connected to the adjusting arm 210 through a connecting piece 250, and the connecting piece 250 is slidably connected to the adjusting arm 210. The quick adjustment part 220 drives the adjusting arm 210 to rotate around the first connecting shaft 240 through the connecting piece 250, thereby driving the wiping roller 120 to approach or move away from the passing roller 110; the fine adjustment part 230 is provided on the frame. When the quick adjustment part 220 drives the adjusting arm 210 to move, the fine adjustment part 230 is separated from the adjusting arm 210. After the quick adjustment part 220 finishes adjusting, the fine adjustment part 230 moves in the direction close to the end where the adjusting arm 210 is connected to the quick adjustment part 220, and drives the adjusting arm 210 to rotate around the first connecting shaft 240 after contacting the adjusting arm 210.

[0046] It can be understood that in order to realize the coordinated adjustment of the quick adjustment part 220 and the fine adjustment part 230, an elastic support member 260 is further provided between the quick adjustment part 220 and the adjusting arm 210. The elastic support member 260 can stably connect and support the quick adjustment part 220 and the adjusting arm 210. When the fine adjustment part 230 adjusts, the deformation of the elastic support member 260 is adapted thereto, and no movement interference will occur. The fine adjustment part 230 and the slight deformation of the elastic support member 260 cooperate to stably realize the fine adjustment of the position of the adjusting arm 210, so that the pressure on the surface of the copper foil can be accurately controlled.

[0047] Please refer to Figures 1 to 4, in an alternative embodiment of the present invention, the adjusting arm 210 is connected to the frame through the first connecting shaft 240. One end of the adjusting arm 210 is connected to the wiping roller 120, and the other end can move under the drive of the quick adjustment part 220 and the fine adjustment part 230. As a result, the adjusting arm 210 can rotate relative to the first connecting shaft 240, driving the wiping roller 120 to move to adjust its proximity to or distance from the passing roller 110. It can be understood that the adjusting arm 210 is essentially a lever structure, and the position of the first connecting shaft 240 is the fulcrum of the lever. On both sides of the first connecting shaft 240 are the first rotating arm 211 and the second rotating arm 212 respectively. The first rotating arm 211 is connected to the quick adjustment part 220 and the fine adjustment part 230, and rotates around the first connecting shaft 240 under their drive, thereby driving the second rotating arm 212 on the other side to move in the opposite direction. The second rotating arm 212 is connected to the wiping roller 120 and can drive the wiping roller 120 to move to approach or move away from the passing roller 110. By using the relative movement of the rotating arms on both sides, the position of the wiping roller 120 is adjusted by controlling the movement of the first rotating arm 211. Using the lever structure, it occupies a small space and is convenient for achieving large-range movement and quick adjustment, with a simple structure and high working efficiency.

[0048] It should be noted that the structure of the adjusting arm 210 is not limited. For example, the lengths of the first rotating arm 211 and the second rotating arm 212 can be the same or different, and the first rotating arm 211 and the second rotating arm 212 can be on the same straight line or not. By adaptively adjusting the structures of the force application end (i.e., the first rotating arm 211) and the force receiving end (i.e., the second rotating arm 212), purposes such as increasing the adjustment range, reducing the occupied space, and improving the driving efficiency can be achieved; the setting position of the first connecting shaft 240 can also be different. For example, the position of the first connecting shaft 240 can be determined in combination with the structure of the adjusting arm 210, so that the two ends of the adjusting arm 210 are approximately symmetrically structured after the wiping roller 120 is adjusted, thereby reducing the influence of gravity on both sides and making the structure more stable. A bearing 214 can also be provided at the connection of the first connecting shaft 240 and connected to the frame through the bearing 214 to reduce the rotational friction and improve the working efficiency.

[0049] Please refer to Figures 1 to 4 , in an alternative embodiment of the present invention, when the end of the adjusting arm 210 connected to the wiping roller 120 rotates relative to the first connecting shaft 240, the position of the wiping roller 120 can be adjusted. Compared with the moving adjustment mechanism, it can effectively save the occupied space, and has a large rotation range and can achieve large-range and quick adjustment. In addition, during the rotation of the adjusting arm 210, it should be ensured that the wiping roller 120 can contact one side of the passing roller 110 to achieve the dust removal and cleaning function. At the same time, for flexible adjustment, the contact position between the wiping roller 120 and the passing roller 110 can be above or below one side of the passing roller 110, and the specific position of the wiping roller 120 is not limited.

[0050] Please refer toFigures 1 to 4 , in an alternative embodiment of the present invention, the quick adjustment part 220 includes a cylinder 221 and a cylinder mounting bracket 222. The cylinder 221 is fixed to the frame through the cylinder mounting bracket 222. The moving end of the cylinder 221 is connected to the first rotating arm 211 on the adjusting arm 210 through a connecting member 250. When the moving end of the cylinder 221 moves up and down, it drives the first connecting arm of the adjusting arm 210 to move up and down through the connecting member 250. Since the cylinder 221 is rotatably connected to the adjusting arm 210 through the connecting member 250 and the connecting member 250 can slide relative to the adjusting arm 210, the adjusting arm 210 can rotate around the first connecting shaft 240 without movement interference. When the adjusting arm 210 rotates, the other end thereof can drive the wiping roller 120 to approach or move away from the passing roller 110; the quick adjustment is realized by driving with the cylinder 221, and the structure is simple and the working efficiency is high. It can be understood that the setting manner of the cylinder 221 is not limited. For example, the moving direction of the cylinder 221 can be substantially perpendicular to the adjusting arm 210 after adjustment, which has good support stability. In other embodiments, the inclination angle between the cylinder 221 and the adjusting arm 210 can be set differently according to the adjustment requirements and the overall structure.

[0051] Please refer to Figures 1 to 4 , in an alternative embodiment of the present invention, the connecting member 250 includes a first slider 251 and a first connecting rod 252. A first sliding groove 213 is correspondingly provided on the adjusting arm 210. The first slider 251 is arranged in the first sliding groove 213 and can slide along the first sliding groove 213. The moving end of the cylinder 221 is rotatably connected to the first slider 251 through the first connecting rod 252. When the position of the moving end of the cylinder 221 changes, under the driving force of the cylinder 221, the first connecting rod 252 and the first slider 251 rotate relative to each other and the first slider 251 can slide in the first sliding groove 213. During this process, the lower adjusting arm 210 is driven to rotate around the first connecting shaft 240, so as to realize the adjustment of the position of the wiping roller 120. It can be understood that the position of the first sliding groove 213 is not limited. For example, the first sliding groove 213 can be arranged inside the adjusting arm 210, or a connecting part can be added above or on the side of the adjusting arm 210 and the first sliding groove 213 can be arranged to achieve a more stable connection and adapt to the movement of the overall structure.

[0052] Specifically, please refer to Figures 1 to 4, a connecting block is provided above the first slider 251. One end of the first connecting rod 252 connected to the first slider 251 can be set as a U-shaped connecting plate shape, and it is stably connected with the connecting block through the second connecting shaft 253. It should be noted that the structure of the connecting member 250 is not limited, as long as it can realize the relative rotation and movement between the quick adjustment part 220 and the adjustment arm 210. For example, the second connecting shaft 253 on the first connecting rod 252 can also be arranged in the first chute 213 so that it can move in the first chute 213, and at the same time, the cylinder 221 can realize relative rotation with the adjustment arm 210 through the second connecting shaft 253.

[0053] Please refer to Figures 1 to 4 , in an alternative embodiment of the present invention, an elastic support member 260 is further provided between the quick adjustment part 220 and the adjustment arm 210. The elastic support member 260 can be, for example, a spring, and can be connected between the moving end of the cylinder 221 and the first connecting rod 252 through a spring. The spring can be sleeved outside the first connecting rod 252, and its two ends are respectively connected to the first connecting rod 252 and the moving end of the cylinder 221. There is a certain distance between the first connecting rod 252 and the end of the cylinder 221 to realize the compression of the spring, and cooperate with the fine adjustment part 230 to realize fine adjustment; during the adjustment of the quick adjustment part 220, the connection of the first connecting rod 252 and the spring can ensure the stability of the overall structure, and when the adjustment of the quick adjustment part 220 is completed, the moving end of the cylinder 221 is fixed. At this time, the cooperation of the fine adjustment part 230 and the deformation of the spring can continue to realize further fine adjustment of the adjustment arm 210. In other embodiments, the elastic support member 260 can also be arranged between the first slider 251 and the first chute 213, or the moving end of the cylinder 221 can be fixed to the first connecting rod 252, and a spring can be arranged inside the connecting rod to realize expansion and contraction, etc.; the elastic support member 260 can also be other structures such as elastic gaskets that can realize stable support and provide a certain amount of deformation.

[0054] Please refer to Figures 1 to 4 , in an alternative embodiment of the present invention, the fine adjustment part 230 includes a mounting frame 231 and an inclined block 232. The mounting frame 231 is fixed to the frame, and the inclined block 232 is arranged at the end of the adjustment arm 210 away from the wiping roller 120, and can apply a force to it for adjustment when it contacts the adjustment arm 210. The inclined block 232 is arranged in the mounting frame 231 and can slide horizontally in the mounting frame 231. When the inclined block 232 slides, its inclined surface contacts the end of the adjustment arm 210 and applies a force to the adjustment arm 210 during the movement, so that it rotates and drives the wiping roller 120 to move.

[0055] During the transmission process, the structure of the inclined block 232 is used to convert the horizontal movement into the rotation of the adjusting arm 210. The fine adjustment is achieved by decomposing the movement. At the same time, it can cooperate with the spring to ensure the stability and accuracy of the fine adjustment, and the adjustment range can be controlled by setting the inclined block 232. The position of the wiping roller 120 is slowly and precisely adjusted by the fine adjustment part 230, which can effectively control the contact degree between the brush of the wiping roller 120 and the surface of the copper foil, ensuring thorough cleaning while avoiding scratching the surface of the copper foil. The structure of the inclined block 232 is not restricted, and the angle and installation structure of the inclined block 232 can be set according to the adjustment needs.

[0056] Please refer to Figures 1 to 4 In an optional embodiment of the present invention, the mounting bracket 231 is connected to the frame by bolts. A second chute is provided at the bottom of the mounting bracket 231, and a second slider is correspondingly provided at the bottom of the inclined block 232. The inclined block 232 and the mounting bracket 231 are slidably connected through the second chute and the second slider. A bolt connecting plate is further provided on one side of the mounting bracket 231, and a bolt connecting hole is provided thereon. One end of the inclined block 232 is connected to the mounting bracket 231 by an adjusting bolt 233. The adjusting bolt 233 can adjust the inclined block 232 to move in the horizontal direction, thereby driving the adjusting arm 210 to rotate around the first connecting shaft 240. The other end of the adjusting arm 210 drives the wiping roller 120 to approach or move away from the passing roller 110.

[0057] Specifically, please refer to Figures 1 to 4 The bolt connecting plate is provided with a threaded hole and is threadedly connected to the adjusting bolt 233. Since the inclined block 232 is slidably connected to the bottom of the mounting bracket 231 and will not rotate relatively, and the bolt connecting plate is fixed to the mounting bracket, one end of the adjusting bolt 233 is rotatably connected to the inclined block 232. By controlling the rotation of the adjusting bolt 233, it moves relative to the bolt connecting plate, thereby driving the inclined block 232 to move. The movement decomposition by the inclined block 232 can achieve fine adjustment. At the same time, combined with the adjusting bolt 233, the differential thread mechanism is used to effectively control the horizontal movement speed and then transmit it to the adjusting arm 210, which can achieve precise fine adjustment and is convenient for operation. In other embodiments, the adjusting bolt 233 may not be rotatably connected to the inclined block 232, and the movement of the adjusting bolt 233 is used to apply a thrust to the inclined block 232 to make it move.

[0058] Please refer to Figures 1 to 4, in an alternative embodiment of the present invention, the inclined block 232 can be disposed, for example, on the right side of the adjusting arm 210. The air cylinder 221 drives one end of the adjusting arm 210 to move upward, causing it to rotate around the first connecting shaft 240. At this time, the other end of the adjusting arm 210 drives the wiping roller 120 to move rapidly downward and approach the passing roller 110. After the rapid adjustment part 220 completes the adjustment, the fine adjustment part 230 moves leftward and approaches one end of the adjusting arm 210. When it continues to move, it will push the adjusting arm 210 upward. When the inclined block 232 moves, the end of the adjusting arm 210 moves relative to the inclined surface of the inclined block 232, and the elastic support member 260 will also deform and be compressed accordingly, so as to realize the rotation of the adjusting arm 210 and finely adjust the position of the wiping roller 120.

[0059] It can be understood that after the rapid adjustment part 220 completes the adjustment, there is a certain distance between the inclined block 232 and the adjusting arm 210. At this time, first move the inclined block 232 leftward to make it contact the adjusting arm 210, and then continue to move to achieve fine adjustment. To ensure the high efficiency of the work, the lengths and positions of the smooth rod section and the threaded section of the adjusting bolt 233 are designed according to the overall structure and movement trajectory of the device, so that the inclined block 232 can quickly approach the adjusting arm 210 by the movement of the smooth rod section of the adjusting bolt 233, and then finely adjust the adjusting arm 210 by the rotation of the threaded structure. In other embodiments, a quick fixing mechanism can also be added between the threaded mounting plate and the bottom of the mounting frame 231, so that the threaded mounting plate and the inclined block 232 as a whole can move quickly on the mounting frame 231, and the inclined block 232 can be adjusted by the adjusting bolt 233 after the threaded mounting plate is fixed, etc.

[0060] It should be noted that the rapid adjustment part 220 and the fine adjustment part 230 are respectively located on both sides of the adjusting arm 210, and cooperate to limit the adjusting arm 210 while adjusting. The specific positions of the rapid adjustment part 220 and the fine adjustment part 230 are not limited, and their movement modes are different according to different structures. For example, in the above embodiment, the inclined block 232 can also be disposed below the adjusting arm 210, and when it moves to the right, it pushes the adjusting arm 210 upward to drive the adjusting arm 210 to rotate; or the wiping roller 120 can also be disposed in the lower space of the passing roller 110, the rapid adjustment part 220 is disposed on the lower side, and the fine adjustment part 230 is disposed on the upper side, and the movement direction of the adjusting arm 210 is opposite to the movement direction in the above embodiment; and there are also many other variable structures.

[0061] Please refer to Figures 1 to 4 , in an alternative embodiment of the present invention, a bearing 214 is further disposed at the end of the adjusting arm 210 connected to the inclined block 232. The inclined block 232 is connected to the inclined block 232 through the bearing 214 and rotates under the movement of the inclined block 232. Through the setting of the bearing 214, the sliding friction between the end of the adjusting arm 210 and the inclined surface of the inclined block 232 is converted into rolling friction, reducing the resistance and effectively improving the movement efficiency.

[0062] Please refer to Figures 1 to 4 In other embodiments, a fine adjustment structure such as a screw adjustment mechanism, a pneumatic fine adjustment mechanism, etc. may also be provided along the vertical direction at one end of the adjustment arm 210. By finely adjusting the displacement in the vertical direction, one end of the adjustment arm 210 is slightly pushed upward to achieve fine adjustment, and together with the quick adjustment mechanism, the two sides of the adjustment arm 210 are limited to ensure the stability of the overall structure.

[0063] Please refer to Figures 1 to 4 In an alternative embodiment of the present invention, the mounting frame 231 and the frame, as well as the adjustment arm 210 and the frame, are detachably connected, which is convenient for component replacement and adjustment, and can be adaptively adjusted according to requirements such as driving efficiency and occupied space to adapt to various situations, with strong practicability.

[0064] Please refer to Figures 1 to 4 In an alternative embodiment of the present invention, before the cleaning process starts, the copper foil is passed through the roller 110 from the bottom, and the air cylinder 221 is started. When the piston of the air cylinder 221 moves, the adjustment arm 210 is driven to rotate around the first connection shaft 240 through the lower connecting member 250, thereby driving the cleaning roller 120 at the other end to move closer to the roller 110. When the brush of the cleaning roller 120 approaches the copper foil, the air cylinder 221 stops operating, and the overall structure remains stable at this time; then, the smooth rod section of the adjustment bolt 233 can be first moved in the threaded hole to drive the wedge block 232 to quickly approach the bearing 214 at the end of the adjustment arm 210, and then by screwing the adjustment bolt 233, the wedge block 232 is driven to move slowly in the horizontal direction. During this process, the spring is compressed, and the bearing 214 rolls on the inclined surface, driving the adjustment arm 210 to slightly rotate around the first connection shaft 240 to achieve fine adjustment of the distance between the cleaning roller 120 and the copper foil, ensuring the cleaning effect and preventing scratches on the surface of the copper foil, etc.; after adjusting to an appropriate position, the motor is started, and the surface of the copper foil is cleaned by the brush on the cleaning roller 120. After the cleaning is completed, the wedge block 232 is moved in the reverse direction away from the adjustment arm 210, and the air cylinder 221 drives the adjustment arm 210 to move in the reverse direction to make the cleaning roller 120 away from the roller 110, which is convenient for operations such as cleaning the cleaning roller 120.

[0065] In summary, the dust removal device of the battery strip cutting machine of the present invention is adjusted by the quick adjustment part 220 and the fine adjustment part 230, and can adapt to the cleaning of copper foils with different thicknesses, with high efficiency and controllable cleaning effect; the adjustment arm 210 is used for transmission, driving one end of the adjustment arm 210 to rotate around the fulcrum to control the movement of the other end, with high efficiency, space saving and large adjustment range; the quick adjustment part 220 and the fine adjustment part 230 are respectively arranged on both sides of the adjustment arm 210, and while cooperating with each other for adjustment, they limit and support the adjustment arm 210 to ensure the stability of the structure; the quick adjustment part 220 adopts a cylinder 221, with a simple structure and high efficiency, and the fine adjustment part 230 uses the structure of the inclined block 232 in cooperation with the threaded structure to achieve precise fine adjustment, while ensuring the structural strength and stability. The adjustment and cooperation of the quick adjustment part 220 and the fine adjustment part 230 are realized through the setting of the elastic support member 260, which can achieve precise adjustment while ensuring the stability of the structure; a bearing 214 is arranged at the end of the adjustment arm 210 to reduce friction and improve the transmission efficiency; the overall structure of the device is simple, easy to operate, with low cost, and each component is convenient for disassembly and replacement, with high flexibility and strong practicability.
