Description

Technical Field

[0001] This application relates to the technical field of pole piece processing equipment, and particularly relates to a tape connecting device and a rewinding equipment. Background Art

[0002] In pole piece processing equipment, the tape connecting operation is a key process for connecting new and old material rolls. Its main purpose is to quickly and accurately connect the new pole piece and the old pole piece through a tape to ensure the continuity of production. However, most of the existing tape connecting operations rely on manual operation. Especially during the material preparation and docking processes, it is often necessary for workers to manually pull the new pole piece near the old pole piece and apply the tape for adhesion. This method is both time-consuming and prone to alignment errors, increasing the downtime of the production line and waste of materials.

[0003] Due to relying on manual material preparation and tape fitting, it often leads to inaccurate docking of pole pieces, thus forming a risk of tape deviation and affecting the overall production quality and efficiency. In addition, the operation skills and experience of workers have a great impact on the quality of tape connection, and it is difficult to achieve standardization. The dependence on manual alignment often requires the equipment to standby for a long time when changing materials, greatly extending the production cycle. Summary of the Invention

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0042] In the pole piece processing equipment, the tape connecting operation is a key process for connecting new and old material rolls. Its main purpose is to quickly and accurately connect the new pole piece and the old pole piece through tape to ensure the continuity of production. However, most of the existing tape connecting operations rely on manual operation. Especially during the material preparation and docking processes, it is often necessary to manually pull the new pole piece to the vicinity of the old pole piece and apply tape for bonding. This method is both time-consuming and prone to alignment errors, increasing the downtime of the production line and the waste of materials.

[0043] Due to the reliance on manual material preparation and tape lamination, the alignment of the electrode tabs is often not precise enough, resulting in the risk of tape offset, which affects the overall production quality and efficiency. In addition, the operation skills and experience of employees have a great impact on the quality of the butt joint tape, and it is difficult to achieve standardization. The dependence on manual alignment often requires the equipment to standby for a long time when changing materials, greatly extending the production cycle.

[0044] Based on this, referring to Figures 1 to 7 As shown, an embodiment of the present invention provides a tape connecting device 10, which includes a frame structure 100 and a tape connecting assembly 200; the frame structure 100 includes a frame body 110 and a moving assembly 120, and the moving assembly 120 is movably connected to the frame body 110; the tape connecting assembly 200 includes a tape connecting mechanism 210, a rotating mechanism 220 and a flipping mechanism 230, the rotating mechanism 220 is connected to the moving assembly 120, the flipping mechanism 230 is connected to the rotating mechanism 220, and the rotating mechanism 220 is used to drive the flipping mechanism 230 to rotate relative to the frame body 110 along a first rotating shaft, the tape connecting mechanism 210 is connected to the output end of the rotating mechanism 220, the flipping mechanism 230 is used to drive the tape connecting mechanism 210 to rotate relative to the frame body 110 along a second rotating shaft, and the tape connecting mechanism 210 is used to clamp and fix the tape; wherein, the first rotating shaft and the second rotating shaft are arranged at intervals; the moving assembly 120 is used to drive the tape connecting mechanism 210 to move relative to the frame body 110, so that the tape connecting mechanism 210 contacts or separates from the tape.

[0045] The tape connecting device 10 of this embodiment can realize automatic tape connecting operation through the cooperation of the set moving receiving part and the tape connecting assembly 200, effectively solving many problems brought by the dependence on manual operation in the tape connecting operation of the transmission equipment.

[0046] Specifically, the device can significantly reduce the risk of material waste in the manual material preparation process. The automatic operation mode reduces the manual pulling and docking of the electrode tabs, thereby reducing the alignment error. In addition, the precise movement and flexible adjustment of the tape connecting mechanism 210 ensure the accuracy of the connection of the electrode tabs, effectively preventing the offset phenomenon of the tape and improving the overall production quality.

[0047] By adopting the rotating mechanism 220 and the flipping mechanism 230, the device can adapt to the changes in the positions of different tapes, realize automatic adjustment, and enable the tape connecting mechanism 210 to perform clamping operations freely under different conditions. This feature not only improves the work efficiency, shortens the standby time during material change, but also minimizes the problem of inconsistent docking quality caused by differences in manual operation skills. The coordinated work of the moving assembly 120 and the tape connecting assembly 200 of the device enables the tape connecting operation to be completed quickly and conveniently, ensuring the continuity of the production line and enhancing the stability of production.

[0048] In summary, the tape splicing device 10 of this embodiment significantly reduces the alignment error and material waste caused by manual operation during the production process by improving the automation level of the tape splicing operation, improves the material utilization rate, and reduces manual intervention and standby time during the roll changing process, thereby optimizing the overall efficiency of the production process.

[0049] In one embodiment, the movable assembly 120 specifically includes a movable base 121 and a movable driver 122. The movable base 121 is connected to the frame 110 via a movable connection structure, enabling relative movement in a predetermined direction relative to the frame 110. The movable driver 122 is fixed to the frame 110 and mechanically connected to the movable base 121. It drives the movable base 121 to move in a linear direction, thereby driving the entire movement of the tape splicing assembly 200, achieving contact or separation between the tape splicing mechanism 210 and the tape.

[0050] The specific implementation of the mobile drive member 122 can include various linear drive elements such as pneumatic push rods, hydraulic push rods and linear modules. Pneumatic push rods have a simple structure and fast response speed, and are suitable for occasions with relatively moderate driving force and stroke requirements. They are also easy to maintain and have low cost. Hydraulic push rods can provide greater thrust and are suitable for applications with heavy loads or high requirements for motion smoothness, but the system complexity and cost are relatively high. Linear modules usually integrate guide rails and drive mechanisms, can provide high-precision, high-rigidity linear motion, and are suitable for production lines with high requirements for motion accuracy and repeatability.

[0051] Specifically, the travel range of the mobile drive member 122 can be determined according to the actual production line pole piece size and layout requirements. For example, the moving distance can be 50mm, 100mm, 150mm, 200mm and other values. The selection of specific values should take into account the space utilization and the effective coverage range of the splicing operation.

[0052] Furthermore, to ensure the accuracy and stability of the movable base 121 during movement, the movable assembly 120 further includes a movable guide 123, through which the movable base 121 is slidably connected to the frame 110. The provision of the movable guide 123 effectively limits the movement direction of the movable base 121, reducing deviation and shaking during movement, thereby significantly improving the positioning accuracy and operating smoothness of the belt splicing mechanism 210.

[0053] The number of movable guides 123 can be one, two, or more depending on actual design requirements. Arranging multiple guides in parallel can enhance the restraining force on the movable base 121, further improving motion stability and repeatability, and preventing swinging or deflection caused by uneven force on a single guide. The specific number should be carefully considered in the design and arrangement based on the travel range, load conditions, and overall device structure.

[0054] Specifically, the moving guide 123 can adopt linear guide rails, linear slide bars and other linear guiding elements. Linear guide rails are usually equipped with rolling elements (such as balls or rollers), which can provide low friction and high rigidity guiding, and are suitable for occasions with high requirements for moving smoothness and accuracy. The linear slide bar has a simple structure and low cost, and can also meet general guiding needs, but it may be slightly inferior to the guide rail in high-load or high-precision scenarios. According to the specific requirements of the production line, appropriate guiding elements can be selected to balance cost, accuracy and durability.

[0055] By reasonably configuring the moving guide 123, the moving seat 121 can slide smoothly along the established linear trajectory under the drive of the moving drive 122, avoiding docking errors caused by non-ideal movements such as tilting and swinging, further ensuring the efficient and accurate operation of the tape splicing mechanism 210, and improving the automation level and production stability of the overall tape splicing device 10.

[0056] Specifically, the tape splicing mechanism 210 is composed of a tape splicing idler 211, a tape splicing pressure block 212 and a tape splicing drive 213, forming an efficient and flexible tape splicing system. The tape splicing drive 213 is connected to the flipping mechanism 230 and is responsible for driving the movement of the tape splicing pressure block 212 relative to the tape splicing idler 211. Specifically, the tape splicing pressure block 212 and the tape splicing idler 211 are spaced apart to form a space for accommodating the tape, thereby realizing the clamping and fixing of the tape.

[0057] The main function of the tape splicing drive 213 is to drive the tape splicing pressure block 212 to move towards or away from the tape splicing idler 211. When the tape splicing drive 213 is activated, the tape splicing pressure block 212 approaches the tape splicing idler 211 to clamp the tape, ensuring that the tape does not slide or shift during the tape splicing process. This design can effectively improve the stability and safety of the tape splicing operation and avoid tape splicing failure caused by improper clamping.

[0058] When using the tape splicing mechanism 210 of this embodiment, first, through the coordinated action of the moving assembly 120, the rotating mechanism 220 and the flipping mechanism 230, the tape splicing mechanism 210 is moved to the preset position. When the tape moves to the opening space of the tape splicing mechanism 210, the tape splicing drive 213 is started to drive the tape splicing pressure block 212 to move towards the tape splicing idler 211 until the two clamp and fix the tape. This process ensures the stability of the tape and provides a reliable basis for subsequent tape splicing operations.

[0059] When it is necessary to release the tape, the tape splicing drive 213 drives the tape splicing pressure block 212 to move in the reverse direction, so that it moves away from the tape splicing idler 211, thereby smoothly releasing the tape. This reverse movement mechanism is flexibly designed, enabling the tape splicing mechanism 210 to quickly respond to production requirements and significantly improving the operation efficiency of the production line.

[0060] Specifically, the tape connecting driving member 213 can adopt linear driving elements such as pneumatic push rods, hydraulic push rods or linear modules. The pneumatic push rod has a fast response and a high load capacity, and is suitable for occasions of rapid clamping and releasing; the hydraulic push rod can provide a greater clamping force and is applicable to applications that require clamping of heavier or thicker tape; the linear module integrates a guide rail and a driving system, can achieve high-precision control, and is suitable for occasions with higher requirements for clamping accuracy.

[0061] In this embodiment, the tape connecting mechanism 210 further includes a tape connecting elastic member 214, and the tape connecting elastic member 214 is respectively connected to the tape connecting pressing block 212 and the flipping mechanism 230. The elastic member undergoes elastic deformation when the tape connecting driving member 213 drives the tape connecting pressing block 212 to move towards the tape connecting roller 211, storing elastic potential energy. When the driving force of the tape connecting driving member 213 is removed, the tape connecting elastic member 214 releases the stored potential energy, prompting the tape connecting driving member 213 to drive the tape connecting pressing block 212 to automatically reset, realizing the elastic return function without additional driving force.

[0062] The setting of the tape connecting elastic member 214 not only realizes the automatic reset of the tape connecting pressing block 212, simplifies the control logic of the driving mechanism, improves the response speed of the action and the reliability of the device, but also effectively avoids the problem that the tape connecting pressing block 212 stays at the clamping position after the driving member stops supplying energy, affecting subsequent operations, and improves the automation continuity of the production line.

[0063] In addition, in some embodiments, the tape connecting elastic member 214 can also be arranged at the contact position between the tape connecting pressing block 212 and the surface of the tape on the side away from the tape connecting roller 211, serving as a buffer device. When the tape connecting driving member 213 drives the tape connecting pressing block 212 to approach or move away from the tape, the elastic member can provide a certain buffer elasticity, relieve the impact force of the tape connecting pressing block 212 on the tape, reduce the mechanical extrusion and damage risk to the pole piece tape, and protect the integrity and surface quality of the tape.

[0064] Specifically, the tape connecting elastic member 214 can adopt various elastic elements such as springs, elastic rubber gaskets, and elastic silicone blocks. The stiffness and deformation amount of the elastic member are designed according to the actual clamping force requirements and the material characteristics of the tape. An overly rigid elastic member may cause unstable clamping and increase the risk of tape sliding; while an overly soft elastic member may not be able to effectively reset or provide sufficient buffering. Therefore, it is necessary to comprehensively consider the clamping force, reset force and buffering effect during design to ensure the stable operation of the tape connecting mechanism 210 and the safety of the tape.

[0065] Furthermore, the tape receiving mechanism 210 further includes a tape receiving sensor 215, which is disposed on the rotating mechanism 220 and is mainly used to obtain the rotation position of the tape receiving mechanism 210 on the flipping mechanism 230 in real time. The introduction of this sensor greatly enhances the automation level of the entire tape receiving process, ensuring the efficient operation and precise control of the equipment.

[0066] Specifically, the tape receiving sensor 215 can be divided into a position sensor 2151 and a sensing element 2152. The position sensor 2151 is fixedly installed on the rotating mechanism 220, while the sensing element 2152 is disposed on the flipping mechanism 230. When the tape receiving mechanism 210 rotates through the flipping mechanism 230, the sensing element 2152 interacts with the position sensor 2151 to form an inductive cooperation. The position sensor 2151 can detect the position information of the sensing element 2152 in real time and feedback this information to the control system to accurately obtain the flipping position of the tape receiving mechanism 210.

[0067] In some embodiments, the position sensor 2151 can adopt a U-shaped photoelectric sensor, and its design can make the moving path of the sensing element 2152 located within the sensing part of the position sensor 2151. The U-shaped photoelectric sensor has the advantages of high sensitivity and fast response, and can capture the position change in time when the tape receiving mechanism 210 makes a small rotation. This setting not only improves the working accuracy of the tape receiving mechanism 210, but also can monitor the position change in real time during the tape receiving process to ensure that each clamping and releasing operation is carried out at the precise preset position.

[0068] In this way, the introduction of the tape receiving sensor 215 enables the tape receiving mechanism 210 to achieve closed-loop feedback control during the operation process, enhancing the automation level and intelligent management ability of the system, and improving the overall production efficiency. Especially in a complex production environment, real-time position monitoring can effectively prevent tape receiving failure caused by incorrect positions, ensuring the stability of the production line and the product quality.

[0069] Furthermore, the end of the tape receiving pressing block 212 facing the opening of the space is provided with a guiding inclined surface 21211, which is arranged at a certain angle with the axial direction of the tape receiving roller 211, and the opening direction of this angle faces the outside of the space. Through this structural design, when the tape enters the space of the tape receiving mechanism 210, it can be guided by the guiding inclined surface 21211 to ensure that the tape smoothly enters the clamping space along the predetermined path.

[0070] The setting of the guiding inclined plane 21211 effectively avoids problems such as jamming and dislocation of the material tape caused by position deviation or inaccurate manual feeding, thereby improving the smoothness and accuracy of the material tape entering the space. Specifically, the included angle formed by the guiding inclined plane 21211 and the tape receiving roller 211 can be adjusted according to the actual width and thickness of the material tape. For example, it can be set at different angles such as 10°, 20°, 30°, etc., and is specifically determined comprehensively according to the physical characteristics of the material tape and the feeding speed. The opening of this included angle faces the outside of the space, which helps to guide the material tape to gradually enter the space instead of suddenly colliding with the roller or the pressing block, reducing the risk of mechanical impact and damage to the edge of the material tape.

[0071] In addition, the surface of the guiding inclined plane 21211 can be made of low-friction materials or undergo surface smoothing treatment to further reduce the friction force between the material tape and the inclined plane, ensuring that the material tape can smoothly slide into the clamping space and improving the efficiency and stability of the overall tape receiving operation.

[0072] In an embodiment, the rotating mechanism 220 includes a carrier 221 and a rotation driving member 222. The rotation driving member 222 is fixedly connected to the moving assembly 120 and can drive the carrier 221 to rotate around the first rotating shaft. The carrier 221 serves as the output end of the rotating mechanism, carrying the flipping mechanism 230 and the tape receiving mechanism 210, and realizing the rotational movement of the overall structure through the driving force of the rotation driving member 222, thereby adjusting the position angle of the tape receiving mechanism 210 relative to the frame body 110.

[0073] The flipping mechanism 230 includes a tape receiving mounting frame 231 and a flipping driving member 232. The flipping driving member 232 is fixedly connected to the carrier 221 and is responsible for driving the tape receiving mounting frame 231 to rotate around the second rotating shaft, realizing the flipping action of the tape receiving mechanism 210. The tape receiving driving member 213 is connected to the tape receiving mounting frame 231, and the angle of the clamping device is adjusted along with the movement of the flipping mechanism 230. This structural design enables the tape receiving mechanism 210 to rotate and flip independently and flexibly in two different rotating shaft directions, improving the adaptability and accuracy of the clamping operation.

[0074] The rotation driving member 222 and the flipping driving member 232 can adopt various rotation driving elements, such as driving motors and rotating cylinders. The driving motor has the advantages of fast response speed, precise control, and flexible adjustment, and is suitable for occasions with high requirements for rotation angle control; the rotating cylinder has a simple structure and stable power output, and is suitable for application environments with light loads and moderate requirements for positioning accuracy. Selecting a suitable rotation driving member according to specific process requirements and equipment layout can balance cost-effectiveness and performance.

[0075] In addition, in order to achieve effective transmission between the power source and the output shaft, the rotary drive member 222 and the flipping drive member 232 are equipped with transmission components such as a speed reducer and a coupling in some embodiments. The speed reducer can reduce the output speed of the high-speed motor, increase the output torque, ensure the smoothness of the rotary motion and sufficient power, and meet the requirements of large loads and high-precision positioning; the coupling is used to connect the power source and the transmission shaft, compensate for the axial, radial, and angular deviations between the two, reduce mechanical vibration, and extend the service life of the equipment.

[0076] In one embodiment, the flipping mechanism 230 further includes a flipping transmission structure 233. The flipping transmission structure 233 is respectively connected to the flipping drive member 232 and the tape receiving mounting bracket 231 in a transmission manner; the flipping transmission structure 233 includes at least one transmission member. When the number of transmission members is multiple, two adjacent transmission members are connected by a transmission shaft 2333, and the transmission member located at the end of the transmission path is connected to the tape receiving mounting bracket 231.

[0077] The purpose of setting the flipping transmission structure 233 is to enhance the adaptability and flexibility of the flipping mechanism 230 to the driving path. Through the cascaded combination of transmission members, it is possible to conveniently adjust the transmission length, direction, and spatial layout between the flipping drive member 232 and the tape receiving mounting bracket 231, so as to meet the requirements of different equipment structures and installation environments. For example, in a production line with limited space or complex layout, the flipping transmission structure 233 can flexibly arrange the positions and angles of the transmission members, avoid interference, and save space.

[0078] In addition, by adopting the method of connecting multiple transmission members through the transmission shaft 2333, it is also possible to adjust the transmission ratio and optimize the transmission efficiency. By reasonably designing the sizes and gear ratios of the transmission members, the flipping mechanism 230 can reduce the driving load while ensuring the accuracy of the clamping action, and improve the overall mechanical performance and service life.

[0079] In one embodiment, the flipping transmission structure 233 specifically includes a first transmission member 2331 and a second transmission member 2332, which are connected by a transmission shaft 2333, and the transmission shaft 2333 is rotatably connected to the carrier 221. The input end of the first transmission member 2331 is directly connected to the output end of the flipping drive member 232, while the output end of the second transmission member 2332 is connected to the tape receiving mounting bracket 231, completing the transmission of power from the flipping drive member 232 to the tape receiving mounting bracket 231.

[0080] The first transmission member 2331 and the second transmission member 2332 are respectively arranged on opposite sides of the carrier 221. This arrangement effectively utilizes the space, makes the overall structure of the tape receiving assembly 200 more compact, facilitates the installation and maintenance of the equipment, and at the same time reduces the possibility of mechanical interference and improves the space utilization rate of the device.

[0081] Specifically, the first transmission member 2331 adopts a belt drive structure. Belt drive has the advantages of simple structure, stable transmission, good buffering performance, low noise, etc. It can effectively absorb part of the vibration, protect the subsequent transmission components, and extend the service life of the equipment. At the same time, belt drive can achieve a certain adjustment of the transmission ratio, which is convenient for adjusting the transmission characteristics of the flipping angle.

[0082] The second transmission member 2332 adopts a gear drive structure. Gear drive has high transmission efficiency and good transmission accuracy, which can ensure that the flipping action of the tape receiving mounting bracket 231 has high positioning accuracy and stability. The gear drive structure has strong rigidity and is suitable for bearing large torques to ensure the reliable operation of the flipping mechanism 230.

[0083] As a connecting bridge between the first transmission member 2331 and the second transmission member 2332, the transmission shaft 2333 is also rotationally connected to the bearing frame 221. While ensuring smooth power transmission, it also guarantees the mechanical rigidity and stability of the entire transmission system. The rotational connection design of the transmission shaft 2333 allows the transmission system to achieve flexible angle adjustment driven by the rotating mechanism 220 to adapt to complex spatial layout requirements.

[0084] In summary, using belt drive as the first transmission member 2331 and gear drive as the second transmission member 2332, connected by the transmission shaft 2333 and distributed on the opposite sides of the bearing frame 221, not only realizes the efficient transmission and precise control of the power output by the flipping drive member 232, but also optimizes the compactness and space utilization rate of the device structure, improves the performance stability and application flexibility of the flipping mechanism 230, and meets the technical requirements of the pole piece tape connecting equipment for high precision and multi-angle adjustment.

[0085] Furthermore, the flipping mechanism 230 further includes a transmission dust cover 234, and the transmission dust cover 234 covers the flipping transmission structure 233. The transmission dust cover 234 can prevent dust, impurities and other foreign objects from entering the interior of the transmission components, reduce wear and corrosion, and significantly improve the durability and stability of the flipping transmission structure 233.

[0086] By setting the transmission dust cover 234, not only the service life of the flipping transmission structure 233 is extended, the maintenance frequency and maintenance cost are reduced, but also the reliable operation of the device in a harsh industrial environment is guaranteed. The material of the dust cover 234 is usually selected from wear-resistant and corrosion-resistant plastics or metal materials, such as engineering plastics, stainless steel or aluminum alloy, taking into account both light weight and protection performance.

[0087] In addition, the design of the transmission dust cover 234 should ensure easy disassembly and installation, which is convenient for regularly checking and maintaining the transmission parts to ensure that the equipment maintains a good operating state for a long time. At the same time, while ensuring the sealing performance, the dust cover should consider the heat dissipation performance to avoid overheating of the transmission structure due to poor heat dissipation, which affects the performance and life of the transmission parts.

[0088] In one embodiment, the tape connecting mount 231 includes a connected mounting portion 2311 and a shaft portion 2312. The shaft portion 2312 is rotatably connected to the tape connecting mount 231, and the tape connecting driving member 213 is connected to the mounting portion 2311.

[0089] Regarding the structural combination mode of the mounting portion 2311 and the shaft portion 2312, a detachable connection mode or an integrally formed structure can be adopted in this embodiment. The specific selection can be weighed according to the equipment maintenance requirements and the structural strength requirements:

[0090] When adopting the detachable connection mode, the mounting portion 2311 and the shaft portion 2312 are assembled by mechanical connection parts such as bolts, pins, and buckles, which is convenient for later maintenance and separate replacement of parts. This structural design has the advantage of convenient maintenance, can quickly replace damaged or worn parts, reduce the equipment downtime and maintenance cost, and is suitable for scenarios with high equipment maintenance frequency or consumable parts in the production environment.

[0091] On the other hand, when adopting the integrally formed structure, the mounting portion 2311 and the shaft portion 2312 are integrally processed and formed, which significantly improves the overall rigidity and structural strength, reduces the looseness and stress concentration at the connection, and improves the stability and durability of the device. In addition, the integrally formed structure simplifies the assembly process, reduces the assembly error, and is suitable for applications with high requirements for high precision and long life.

[0092] Further, the rotating mechanism 220 further includes a rotating carrier 223. The rotating carrier 223 is connected to the moving seat 121, and the driving shaft 2221 of the rotation driving member 222 is rotatably connected to the rotating carrier 223. By providing the rotating carrier 223, the rotational movement of the driving shaft 2221 can be effectively supported and guided, and the rotation smoothness and stability of the driving shaft 2221 can be improved.

[0093] The rotating carrier 223 generally adopts a bearing structure, such as a rolling bearing or a sliding bearing, which can reduce the friction and wear during rotation, reduce the movement resistance, and ensure the stable transmission of the rotation driving member 222 when outputting torque. The reasonable design and layout of the rotating carrier 223 help to prevent the driving shaft 2221 from yawing and jittering due to uneven force or vibration, and ensure the accuracy and reliability of the overall movement of the rotating mechanism 220.

[0094] In one embodiment, the rotating carrier 223 specifically includes a carrier cylinder portion 2231 and a carrier bearing 2232. The carrier cylinder portion 2231 is connected to the moving seat 121 and serves as the main structure of the rotating carrier, responsible for fixing and supporting the carrier bearing 2232. The carrier bearing 2232 is installed inside the carrier cylinder portion 2231 to support the driving shaft 2221 of the rotation driving member 222 and realize its stable and efficient rotational movement.

[0095] In a preferred embodiment, the number of load-bearing bearings 2232 is at least two, and the two load-bearing bearings 2232 are coaxially arranged. By providing at least two coaxial load-bearing bearings, the radial and axial support capabilities of the rotary load-bearing member 223 for the drive shaft 2221 can be significantly improved, the stability during rotation can be enhanced, and yaw, vibration, or premature wear of the drive shaft caused by uneven stress can be prevented.

[0096] The axial spacing formed between the two coaxial load-bearing bearings 2232 helps to disperse the load, improve the rigidity and load-bearing capacity of the entire rotary mechanism 220, and ensure the transmission stability and accuracy when the rotary drive member 222 outputs torque. In addition, the use of multiple load-bearing bearings 2232 can also effectively extend the service life of the drive shaft 2221 and the rotary load-bearing member 223, and reduce the maintenance frequency and maintenance cost of the equipment.

[0097] The load-bearing bearing 2232 can be selected from rolling bearings (such as deep groove ball bearings, cylindrical roller bearings) or sliding bearings, which is specifically determined according to the load size, speed requirements, and environmental conditions. The material of the bearing cylinder part 2231 can be made of high-strength metal materials, such as aluminum alloy or steel, to ensure the structural strength and durability.

[0098] In one embodiment, the tape connecting block 212 is composed of a crimping part 2121, a connecting part 2122, and a guide rod part 2123. The crimping part 2121 extends outward from the connecting part 2122 and is arranged on the opposite side of the tape connecting roller 211, and a space for clamping the tape is formed between the two, so as to realize the clamping, fixing, or releasing of the tape. The connecting part 2122 is connected to the tape connecting driving member 213 and is responsible for transmitting the driving force to the crimping part 2121 to drive it to complete the clamping action.

[0099] The guide rod part 2123 is slidably matched with the tape connecting mounting frame 231 and serves as the guiding and supporting structure of the crimping part 2121, ensuring that the crimping part 2121 moves smoothly along a predetermined direction during the process of clamping and releasing the tape, avoiding deviation or jamming, and improving the stability and accuracy of the clamping action.

[0100] When the tape connecting elastic member 214 is a helical spring, the spring can be sleeved on the guide rod part 2123 to realize the coaxial arrangement of the elastic member and the block structure. This design is not only convenient for installation, disassembly, and maintenance, but also makes the overall structure more compact and saves space. At the same time, the elastic deformation of the helical spring directly acts on the guide rod part 2123, and the automatic reset function of the crimping part 2121 is realized through the resilience of the spring, simplifying the control logic of the drive system and improving the response speed and reliability of the device.

[0101] In addition, the helical spring is sleeved on the guide rod portion 2123, which is beneficial to the uniform force of the spring, reduces local stress concentration, and prolongs the service life of the spring and the guide rod portion 2123. This structural design can also effectively buffer the impact force generated during the clamping process, protect the strip from being damaged due to excessive clamping, and at the same time ensure that the clamping force is stable enough to meet the requirements of high-quality tape splicing operation.

[0102] In one embodiment, the number of the tape splicing mechanisms 210 is multiple groups, and at least two groups of the tape splicing mechanisms 210 are arranged at intervals, capable of simultaneously clamping and fixing multiple strips. This design significantly improves the efficiency of the tape splicing operation and adapts to the production requirements of higher production capacity.

[0103] The tape splicing assembly 200 further includes a cutting mechanism 240. The cutting mechanism 240 is located between two adjacent tape splicing mechanisms 210, forming an integrated tape splicing and cutting system. The cutting mechanism 240 includes a cutting knife 241 and a cutting driving member 242. The cutting driving member 242 is connected to the rotating mechanism 220 and is responsible for driving the cutting knife 241 to move relative to the tape splicing mechanism 210. Specifically, the cutting knife 241 is connected to the output end of the cutting driving member 242 and can perform a cutting operation after the tape splicing mechanism 210 clamps and fixes the strip.

[0104] After the two tape splicing mechanisms 210 clamp and fix the strip, the cutting driving member 242 can be started to drive the cutting knife 241 to move for precise cutting of the strip. This process realizes the automatic cutting function, greatly improves the automation level and working efficiency of the production line, reduces the need for manual operation, and reduces the errors introduced by manual operation.

[0105] Specifically, the cutting driving member 242 can adopt various linear driving elements such as a pneumatic push rod, a hydraulic push rod or a linear module. The pneumatic push rod is suitable for occasions of rapid cutting due to its fast response speed and stable torque output; the hydraulic push rod can provide greater force and is suitable for cutting thicker or harder strips; the linear module can realize high-precision motion control to ensure the accuracy and stability of the cutting process.

[0106] By effectively integrating the cutting mechanism 240 with the tape splicing mechanism 210, not only the production process is optimized and the working efficiency is improved, but also the precise control and processing of the strip during the tape splicing process are ensured, enhancing the functionality and flexibility of the entire tape splicing device 10 and meeting the requirements of high efficiency and automation for modern production lines.

[0107] In one embodiment, the blade of the cutting knife 241 is arranged at a certain angle with the axial direction of the tape receiving roller 211, and the opening of the angle R faces the opening direction of the tape receiving space formed between the tape receiving roller 211 and the tape receiving pressing block 212. This design enables the cutting knife 241 to first contact the tape from the side close to the opening of the space when contacting the tape. As the cutting knife 241 moves along the set path, the cutting area of the cutting knife 241 gradually expands, and the cutting of the tape is gradually completed. This progressive cutting method helps to reduce the instantaneous impact force on the tape, avoid the tape from being torn or deformed due to excessive sudden force, and thus significantly improve the neatness and quality of cutting.

[0108] Specifically, the angle between the cutting knife 241 and the axial direction of the tape receiving roller 211 can be adjusted within a certain range according to the material, thickness of the tape and the requirements of the cutting process, such as angles of 1°, 2°, 3°, 5°, 10°, etc. The specific value can be flexibly set according to the actual application environment. The opening of the angle faces the opening of the space, which is beneficial for the cutting knife 241 to smoothly enter the tape clamping space and realize the cutting action from shallow to deep, effectively improving the stability and accuracy of the cutting process.

[0109] In a preferred embodiment, the edge of the cutting knife 241 is designed with serrations. Compared with a straight-edge blade, a serrated blade can produce a stronger grasping and cutting effect during cutting, disperse the cutting force, reduce the frictional resistance and heat accumulation during cutting, and reduce the risk of burrs and tears on the edge of the tape. The serrated edge can also effectively adapt to tapes with different hardnesses and thicknesses, improve the cutting quality and the tool life, so as to ensure the neat cutting of the tape in the tape connecting operation and promote the smooth progress of subsequent processes.

[0110] In summary, by reasonably setting the angle between the cutting knife 241 and the axial direction of the tape receiving roller 211 and its opening direction, combined with the serrated edge design, not only the mechanical process of the cutting action is optimized, the smoothness and uniformity of cutting are improved, but also the cutting quality is significantly improved, ensuring the stability of the tape during the automatic tape connecting and cutting process and the product quality.

[0111] Furthermore, the cutting mechanism 240 further includes a cutting dust cover 243. The cutting dust cover 243 is connected to the cutting driving member 242, and its opening faces the cutting knife 241, aiming to effectively receive and collect tape debris, dust and other impurities generated during cutting. This design not only helps to keep the production environment clean, prevent the diffusion of impurities from causing equipment or environmental pollution, but also reduces the impact of impurities on subsequent processes, ensuring product quality and production safety.

[0112] In addition, when the cutting driving member 242 is in a contracted state, the cutting knife 241 can be accommodated inside the cutting dust hood 243, thereby effectively protecting the cutting knife 241. This protection structure prevents the cutting knife 241 from being exposed to the external environment in a non-working state, reduces the risk of accidental collision, abrasion or damage, extends the service life of the cutting knife 241, and improves the reliability and safety of the equipment.

[0113] The material of the cutting dust hood 243 is usually selected as wear-resistant and easy-to-clean metal or engineering plastic. Combined with a reasonable sealing design, it ensures stable operation in a high-frequency operation environment. In addition, the structure of the cutting dust hood 243 should be convenient for disassembly and maintenance, facilitating the regular cleaning of the collected impurities and maintaining the good working condition of the device.

[0114] In this embodiment, the tape connecting device 10 further includes a pressure roller assembly 300, and the pressure roller assembly 300 is composed of a roller body 310 and an adjusting assembly 320. The adjusting assembly 320 is fixedly connected to the frame body 110, and the roller body 310 is movably connected to the frame through the adjusting assembly 320. The roller body 310 is mainly used for pressing the tape to ensure the stability and accuracy of the tape during transportation and positioning. At the same time, the adjusting assembly 320 drives the movement of the roller body 310 to push and move the tape, assisting the tape to accurately reach the preset position.

[0115] During specific use, the roller body 310 is pressed against the surface of the tape by the driving force of the adjusting assembly 320 to form sufficient friction to drive the tape to move along the established direction. The adjusting assembly 320 can flexibly adjust the position of the roller body 310 and the applied pressure according to the preset operation requirements in the production process to adapt to tapes of different thicknesses, materials and widths. The position adjustment range of the roller body 310 can include fine adjustment up and down or back and forth to ensure the smooth and accurate transportation of the tape under the action of the pressure roller.

[0116] Subsequently, the rotating mechanism 220 and the flipping mechanism 230 drive the tape connecting mechanism 210 to move to the position where the tape is located and adjust it to a suitable clamping posture; at the same time, the moving component 120 drives the tape connecting mechanism 210 to achieve further precise positioning, so that the tape can be smoothly accommodated between the tape connecting idler 211 and the tape connecting pressure block 212 to complete precise clamping.

[0117] Through the coordinated cooperation of the pressure roller assembly 300 and the tape receiving assembly 200, the entire tape receiving operation process realizes the stable conveying, precise positioning, and automatic clamping of the tape, effectively avoiding the docking errors caused by tape slack and position deviation, and improving the tape receiving quality and production efficiency. Specifically, the adjusting assembly 320 includes a pressure roller mounting frame 321 and a pressure roller driving member 322. The pressure roller driving member 322 is connected to the frame body 110, the pressure roller mounting frame 321 is connected to the output end of the pressure roller driving member 322, and the roller body 310 is arranged on the pressure roller mounting frame 321. The pressure roller driving member 322 is used to drive the pressure roller mounting frame 321 to move relative to the machine frame.

[0118] Specifically, the pressure roller driving member 322 can adopt linear cylinders or linear modules and other linear driving elements. Linear cylinders have the advantages of rapid response and simple operation, and are suitable for application scenarios with high requirements for pressure and speed; while linear modules integrate rails and driving mechanisms, and can provide higher positioning accuracy and repeatability, and are suitable for precision control requirements.

[0119] Through the driving of the pressure roller driving member 322, the pressure roller mounting frame 321 can move smoothly on the machine frame 110, driving the movement of the roller body 310 relative to the frame body 110, so as to realize the adaptive adjustment of tapes with different materials and thicknesses. This design ensures that the roller body 310 can flexibly adjust the pressure applied to the tape according to the actual operation requirements, and guarantee the stability and conveying efficiency of the tape.

[0120] During the use process, the motion control of the pressure roller driving member 322 can be combined with sensor feedback for closed-loop control to further improve the accuracy and response speed of the adjustment. This setting not only simplifies the operation process, but also can effectively reduce the docking errors caused by improper adjustment, and improve the overall quality and efficiency of the tape receiving operation.

[0121] In one embodiment, the number of the pressure roller assemblies 300 is at least two groups, and two groups of pressure roller assemblies 300 are arranged at intervals on the opposite sides of the tape receiving assembly 200. This arrangement method can realize the synchronous or alternating conveying and pressing of two groups of tapes, greatly improving the operation efficiency and automation level of the tape receiving device 10.

[0122] Through the coordinated cooperation of two groups of pressure roller assemblies 300 and the tape receiving assembly 200, the tape receiving device can press and move two groups of tapes simultaneously or in sequence, so that the tapes can quickly and accurately reach the clamping area of the tape receiving mechanism 210, facilitating the efficient clamping and connection operations of the tape receiving mechanism 210. This design not only meets the requirements of parallel processing of multiple tapes, but also can shorten the material change time, reduce the equipment standby time, and improve the continuity and stability of the production line.

[0123] Furthermore, the adjusting assembly 320 further includes a roller limiting member 323 and / or a roller buffer member 324, which are respectively arranged at the end of the moving path of the roller body 310 to ensure the safety and reliability of the movement of the roller body 310.

[0124] The main function of the roller limiting member 323 is to physically limit the moving stroke of the roller body 310, prevent the roller body 310 from exceeding the predetermined moving range, and thus avoid mechanical collision or structural damage caused by excessive movement. The limiting member 323 can adopt forms such as a mechanical stop block, a limit switch or a photoelectric sensor, and realizes precise stroke control through linkage with the control system to ensure that the roller body 310 operates within a reasonable range and improves the safety and stability of the equipment.

[0125] The roller buffer member 324 is used to provide flexible buffering when the roller body 310 moves to the end of the path, and relieve the impact force between the roller body 310 and the limiting device or the frame structure. The buffer member 324 is usually made of elastic materials such as a rubber buffer pad, a spring buffer block or an airbag-type buffer device, which can effectively absorb the impact energy, reduce mechanical vibration and noise, extend the service life of relevant components, and improve the working stability and comfort of the equipment.

[0126] In practical applications, the roller limiting member 323 and the roller buffer member 324 can be set separately or used in cooperation. The limiting member 323 ensures that the roller body 310 does not cross the boundary, and the buffer member 324 reduces the impact during the limiting process. The combination of the two provides a safe and reliable movement protection solution for the roller body 310.

[0127] The tape connecting device 10 of this embodiment realizes the automatic roll change and tape connecting operations of the pole piece coil through the coordinated cooperation of multiple mechanisms, ensuring the continuity and high efficiency of the production process.

[0128] The specific operation principle is as follows:

[0129] When the first coil on the first coil shaft is loaded, the production line needs to be changed to the second coil for continuous feeding. At this time, the adjusting assembly 320 in the first group of roller assemblies 300 drives the roller body 310 to press down, presses the pole piece on the first coil, and stably pulls it to the preset tape running position. Subsequently, the rotating mechanism 220 is started, driving the whole tape connecting mechanism 210 to rotate to the predetermined position. At this time, the tape connecting driving member 213 remains open to prepare for the clamping action of the tape connecting mechanism 210.

[0130] Cooperating with the rotation of the flipping driving member 232 of the tape connecting mechanism 210, the tape connecting mechanism 210 adjusts to a suitable clamping angle so that the tape connecting roller 211 and the tape connecting pressing block 212 can be inserted into the space formed between the pole pieces to ensure that the pole pieces can enter the clamping area completely and smoothly.

[0131] Next, the moving component 120 drives the moving seat 121 to advance forward, pushing the pole piece completely into the clamping space between the tape receiving roller 211 and the tape receiving pressing block 212. At this time, the tape receiving driving member 213 contracts, driving the tape receiving pressing block 212 to approach the tape receiving roller 211, realizing the clamping and fixing of the pole piece, and ensuring the stability of the pole piece during the tape receiving process.

[0132] After the clamping is completed, the cutting driving member 242 is activated, driving the cutting knife 241 to extend and move along the direction of the material tape, precisely cutting the pole piece of the second material roll, and realizing the automatic disconnection of the material tape.

[0133] After the cutting is completed, the adjusting component 320 drives the pressing roller assembly 300 to rise, and the rotating mechanism 220 drives the tape receiving mechanism 210 to rotate to the position of the first material roll, and rotates in cooperation with the flipping driving member 232, so that another group of pressing roller assemblies 300 are pressed against the tape of the first material roll, and rotate synchronously with the first material shaft, driving the first material roll and the second material roll to achieve smooth docking.

[0134] After the docking is completed, the rotating mechanism 220 rotates the tape receiving mechanism 210 back to the middle position, the moving component 120 contracts, and the tape receiving mechanism 210 retracts from the outside of the pole piece to the non-operation area, completing the entire automatic tape receiving operation process.

[0135] Through the above steps, the tape receiving device 10 realizes the automatic roll change and tape receiving of the pole piece material roll, greatly reducing manual intervention, improving the accuracy and stability of tape receiving, shortening the roll change time, and enhancing the continuity and efficiency of the production line. The coordinated actions between the various mechanisms ensure the precise control of the pole piece during movement, clamping, cutting, and docking, avoiding tape offset and material waste, and meeting the requirements of efficient and standardized pole piece processing and production.

[0136] The present invention also provides a roll change device, which includes a processing device, a pay-off device, and the tape receiving device 10 in any one of the above embodiments; the processing device is used for processing the material tape; the pay-off device is used for carrying the material roll and conveying the material tape to the processing device; the tape receiving device 10 is arranged on one side of the pay-off device, and the tape receiving device 10 is used for connecting an external material roll with the material tape.

[0137] The tape receiving device 10 of this embodiment realizes the automatic adaptation and clamping of the material tape at different positions and angles through the multi-degree-of-freedom adjustment of the rotating mechanism 220 and the flipping mechanism 230, ensuring the stability and high-precision connection of the material tape clamping. The precise movement and flexible adjustment of the tape receiving mechanism 210 effectively prevent the tape from shifting, ensuring the quality and consistency of the pole piece connection, and significantly improving the overall quality level of the produced products.

[0138] In addition, through automated tape splicing operations, this roll-changing device significantly reduces the risk of material waste during manual material preparation, reduces errors caused by manual pulling and docking, standardizes and streamlines the tape splicing operation, and avoids quality inconsistencies caused by differences in operator skills.

[0139] The cooperation between the moving component 120 and the tape splicing component 200 of the device shortens the standby time during material change, improves the continuity and stability of the production line, and effectively enhances production efficiency and capacity. The coordinated operation of the automatic cutting mechanism and the pressure roller assembly further ensures the smooth and precise conveyance of the tape, achieving full-process automation of the pole piece tape from conveyance, clamping, cutting to tape splicing.
