Description

Technical Field

[0001] This utility model relates to the field of production equipment technology, and in particular to a winding and unwinding device. Background Technology

[0002] Traditional winding and unwinding equipment generally suffers from the following technical defects in the process of winding and unwinding materials (such as electrode sheets):

[0003] (1) Insufficient material feeding and positioning accuracy: In the initial material feeding stage, due to the lack of a precise and effective positioning mechanism in traditional equipment, the material is prone to displacement during feeding. This displacement will directly lead to the material not being able to be wound neatly and orderly in the subsequent winding process, which will have a negative impact on the quality of a series of subsequent processing stages. For example, in the winding process of battery electrodes, if the electrodes are not wound evenly, it may cause uneven distribution of electrodes inside the battery, affecting the battery's charging and discharging performance and service life, and reducing the overall quality of the product.

[0004] (2) Low material feeding efficiency: Traditional winding and unwinding equipment mostly adopts manual feeding. This method not only requires a lot of manpower and time, increasing production costs and production cycle, but also makes it difficult to avoid material damage due to improper operation or negligence during manual operation. Once the material is damaged during feeding, it will not only waste raw materials, but also affect the integrity and quality stability of the product, causing unnecessary economic losses to the enterprise.

[0005] The aforementioned problems severely restrict production efficiency and product quality. In today's increasingly competitive market with ever-higher requirements for production efficiency and product quality, in order to enhance the core competitiveness of enterprises and meet the market's demand for high-quality products, it is urgent to develop a set of automated and precise unwinding and rewinding solutions through structural innovation to overcome the shortcomings of traditional equipment and promote the further development of the industry.

[0067] Please refer to Figure 1-2 This utility model provides a winding and unwinding device, including a frame 1, a main body component 2, and a loading and unloading auxiliary mechanism 3; wherein,

[0068] The frame 1 serves as the supporting framework for the entire equipment, providing a stable and reliable mounting foundation for other components. It possesses sufficient strength and rigidity to ensure that it can withstand various external forces without deformation during equipment operation, thus guaranteeing the normal operation of the equipment. The main body component 2 and the loading / unloading auxiliary mechanism 3 are precisely mounted on the frame 1, with clear positional relationships between the components, working together to achieve efficient equipment operation.

[0069] The main body component 2 plays a crucial role in the equipment, primarily used for winding or unwinding various materials. During production, the main body component 2 can flexibly adjust its working mode according to different process requirements, orderly winding the material into rolls or smoothly unwinding it, providing the required material form for subsequent processing steps.

[0070] The loading / unloading auxiliary mechanism 3 is an innovative highlight of this embodiment, playing a crucial role in the loading and unloading processes of the equipment. During the loading stage, the loading / unloading auxiliary mechanism 3 uses a carefully designed mechanical limiting structure to precisely limit the position of the material on the main body component 2. This mechanical limiting method has high accuracy and stability, ensuring zero positional deviation of the material during initial loading, fundamentally avoiding the uneven winding problem caused by loading deviation in traditional equipment. Taking the production of battery electrodes as an example, uneven winding leads to uneven electrode distribution inside the battery, thus affecting key indicators such as charge / discharge performance and cycle life. The loading / unloading auxiliary mechanism 3 of this embodiment effectively solves this problem, providing a strong guarantee for the production of high-quality battery products.

[0071] During the material unloading stage, the loading / unloading auxiliary mechanism 3 also performs excellently. It automatically and smoothly pushes the material out of the main component 2, achieving automated operation of the unloading process. Compared to the manual unloading method used in traditional equipment, automatic unloading not only greatly improves unloading efficiency and shortens the production cycle, but also completely eliminates the risk of material damage caused by human factors. In manual unloading, due to factors such as the operator's skill level and fatigue, it is easy to damage the material during operation, leading to waste of raw materials and increased production costs. In this embodiment, the loading / unloading auxiliary mechanism 3, through automated operation, effectively reduces the raw material loss rate and improves the company's economic benefits.

[0072] In summary, this embodiment, by adding the loading and unloading auxiliary mechanism 3, successfully achieved precise positioning of material loading and automated unloading, resulting in significant improvements in production efficiency and product quality. Specifically, precise loading positioning ensures the stability and consistency of the material during subsequent processing, laying the foundation for producing high-quality products; automated unloading improves the smoothness and continuity of the production process, reducing production interruptions and waiting time, thereby significantly improving overall production efficiency.

[0073] This solution, while ensuring product processing quality, significantly improves the automation level of the production process, providing the entire industry with a more reliable and efficient unwinding and rewinding operation mode. This advanced operation mode not only helps companies reduce production costs and improve product quality, but also enhances their competitiveness in the market, powerfully promoting a dual improvement in production efficiency and product quality. It is of great significance for promoting technological progress and development throughout the industry.

[0074] Please refer to this again. Figure 1-2 and in conjunction with references Figure 3 In one embodiment of this invention, the loading and unloading auxiliary mechanism 3 is carefully designed and cleverly combined from two key parts: a limiting plate 31 and a telescopic mechanism 32. The two work together to achieve efficient and precise loading and unloading auxiliary functions.

[0075] The telescopic mechanism 32, as the core power and adjustment component of the loading / unloading auxiliary mechanism 3, achieves a stable and flexible connection with the limiting plate 31. This telescopic mechanism 32 has two important functions: First, it can precisely adjust the limiting position of the limiting plate 31 through its telescopic movement. In actual production, since the width of materials used in different batches and specifications of products may vary, this adjustability is particularly important. Through the adjustment of the telescopic mechanism 32, the limiting plate 31 can adapt to materials of various widths, ensuring effective material limiting in different production scenarios, greatly improving the versatility and applicability of the equipment. Second, the telescopic mechanism 32 drives the limiting plate 31 to move smoothly and orderly between the limiting position and the push-out position through its telescopic movement. This precise control of movement is a key link in achieving automated loading and unloading, enabling the limiting plate 31 to accurately reach the designated position at different working stages, providing reliable assurance for loading and unloading operations.

[0076] The limiting plate 31 plays a crucial role in the loading and unloading auxiliary mechanism 3, directly interacting with the material. During the loading stage, when the material is ready to be placed on the main body component 2, the limiting plate 31 is in a pre-set limiting position and tightly abuts against the end of the material. This abutment method provides a clear positioning reference for the material, effectively preventing the material from shifting during the loading process and ensuring that the material is accurately placed in the designated position on the main body component 2. This lays a good foundation for subsequent winding or unwinding operations, avoiding problems such as uneven winding and processing errors caused by inaccurate loading, and ensuring the initial quality of the product.

[0077] During the unloading stage, the telescopic mechanism 32 begins to operate according to a preset program, driving the limiting plate 31 to move towards the material. Once the limiting plate 31 contacts the end of the material, an appropriate pushing force is applied to smoothly and slowly push the material out of the main body component 2. As the telescopic mechanism 32 continues to extend and retract, the limiting plate 31 pushes the material until it reaches the preset ejection position, completing the entire unloading process.

[0078] In summary, in this embodiment, the loading and unloading auxiliary mechanism 3, through the close cooperation of the limiting plate 31 and the telescopic mechanism 32, achieves precise loading and limiting of materials of different widths and automated unloading and pushing, providing strong support for the stable operation and efficient production of the entire winding and unwinding equipment.

[0079] Please refer to this again. Figure 3 In one embodiment of this invention, the telescopic mechanism 32 adopts a scientific, reasonable, efficient and stable design architecture, mainly composed of two core components: the telescopic electric cylinder 321 and the guide column 322. The two components work together to complement each other and provide a reliable guarantee for the precise movement of the limiting plate 31.

[0080] The telescopic electric cylinder 321, as the core power output component of the telescopic mechanism 32, possesses powerful driving capabilities and precise control performance. Its telescopic end is securely and tightly connected to the limiting plate 31, ensuring that the telescopic electric cylinder 321 transmits power to the limiting plate 31 without loss during operation. In actual operation, the telescopic electric cylinder 321 precisely executes its telescopic movements according to a pre-set control program. When material loading is required, the telescopic electric cylinder 321 accurately moves the limiting plate 31 to the limiting position according to the material specifications and loading requirements, providing a precise positioning reference for the material. When the unloading stage arrives, the telescopic electric cylinder 321 exerts force again, pushing the limiting plate 31 towards the material according to a predetermined stroke and speed, until the material is smoothly pushed out of the main body component 2 to the unloading position. This precise telescopic control of the telescopic electric cylinder 321 ensures that the movement of the limiting plate 31 strictly conforms to the requirements of the production process, laying a solid foundation for automated and efficient loading and unloading operations.

[0081] The guide post 322 plays a crucial guiding role in the telescopic mechanism 32. It achieves a reliable connection with the limiting plate 31, typically using a high-precision connection method, such as linear bearings, to ensure smooth, low-friction relative movement between the guide post 322 and the limiting plate 31. During operation, the guide post 322, with its straight and high-precision structure, provides a clear predetermined path for the movement of the limiting plate 31. Regardless of how the telescopic cylinder 321 drives the limiting plate 31 to telescopic movement, the guide post 322 consistently guides the limiting plate 31 to move stably along the predetermined straight line, effectively preventing deviations or wobbling during movement. This precise guiding function is of paramount importance for ensuring the accuracy and stability of loading and unloading operations. Especially when handling materials requiring extremely high positional accuracy, the guide post 322 ensures that the limiting plate 31 accurately reaches the designated position, thereby achieving precise material limiting and ejection, greatly improving product processing quality and production efficiency.

[0082] In summary, in this embodiment, the telescopic mechanism 32 is powered by the telescopic electric cylinder 321 and precisely guided by the guide column 322. The two are organically combined and work together, enabling the limiting plate 31 to move accurately and stably during the loading and unloading process.

[0083] In one embodiment of this invention, the key components of the telescopic mechanism 32 have been designed in a more refined and specialized manner. Specifically, the telescopic electric cylinder 321 adopts a multi-section telescopic electric cylinder, and the guide column 322 adopts a multi-section guide column. This unique design combination brings significant advantages to the stable operation and efficient operation of the entire winding and unwinding equipment.

[0084] As the power core of the telescopic mechanism 32, the multi-section telescopic electric cylinder possesses many outstanding characteristics compared to the traditional single-section telescopic electric cylinder. Structurally, the multi-section telescopic electric cylinder consists of multiple nested telescopic sections. This layered design allows it to achieve a wider range of telescopic strokes within a limited space. In actual production, due to the significant differences in the dimensions of materials of different specifications, diverse requirements are placed on the movement range of the limiting plate 31. The large-stroke telescopic capability of the multi-section telescopic electric cylinder allows the limiting plate 31 to be flexibly adjusted to appropriate limiting and ejection positions according to the width of different materials and loading / unloading requirements, greatly improving the versatility and adaptability of the equipment and meeting the needs of various production scenarios.

[0085] The multi-section guide post works in conjunction with the multi-section telescopic electric cylinder to provide more precise and reliable guidance support for the movement of the limiting plate 31. The multi-section guide post is also composed of multiple guide sections, and its structural design matches the multi-section telescopic electric cylinder. It can extend and retract synchronously with the telescopic electric cylinder, always maintaining a tight connection and effective guidance with the limiting plate 31.

[0086] In summary, this embodiment adopts a design with multiple telescopic electric cylinders and multiple guide columns, which fully leverages the advantages of both and achieves high-performance and high-precision operation of the telescopic mechanism 32.

[0087] Please refer to this again. Figure 3 In one embodiment of this invention, the loading / unloading auxiliary mechanism 3 is further enhanced with two key components—a loading limit sensor 33 and a unloading limit sensor 34—to improve automation and operational accuracy. These two sensors act as the equipment's "intelligent eyes," accurately sensing the position of the limit plate 31 and providing a reliable guarantee for the stable and efficient operation of the entire loading / unloading process.

[0088] The material feeding limit sensor 34 plays a crucial role in the material feeding process. When the telescopic mechanism 32 drives the limit plate 31 to begin the feeding operation—that is, to move it towards the material to push it off the main body component 2—the material feeding limit sensor 34 enters its working state. It continuously monitors the movement position of the limit plate 31 in real time, and using advanced sensing technology, it can accurately sense changes in the distance between the limit plate 31 and the preset ejection position. Once the limit plate 31 moves to the ejection position, the material feeding limit sensor 34 immediately detects this state and quickly transmits the detection signal to the equipment's control system.

[0089] Upon receiving the signal, the control system immediately instructs the telescopic mechanism 32 to stop, ensuring that the limit plate 31 accurately stops at the ejection position, preventing damage to the material or equipment due to excessive movement. This precise detection and control mechanism enables a high degree of automation and accuracy in the material feeding process, greatly improving feeding efficiency while ensuring the integrity and quality stability of the material during feeding. For example, in production scenarios with extremely high requirements for product dimensional accuracy, the feeding limit sensor 34 can ensure that the material is accurately ejected to the designated position, providing qualified raw materials for subsequent processing steps, thereby effectively improving the product qualification rate of the entire production process.

[0090] The loading limit sensor 33 plays a crucial role in the loading stage. When preparing for the loading operation, the telescopic mechanism 32 drives the limit plate 31 to the limit position according to a preset program, providing precise positioning for the material loading. The loading limit sensor 33 operates continuously throughout the movement, tracking and detecting the position of the limit plate 31 in real time. It can sensitively sense changes in the distance between the limit plate 31 and the limit position. When the limit plate 31 accurately reaches the limit position, the loading limit sensor 33 quickly captures this signal and promptly transmits it to the control system.

[0091] Based on the received signal, the control system determines that the limit plate 31 is in the correct limit position, at which point the material feeding operation can begin. The presence of the feeding limit sensor 33 ensures that the limit plate 31 accurately reaches the designated position each time material is fed, providing a stable and reliable positioning reference for the material and effectively avoiding problems such as uneven winding and processing errors caused by feeding position deviations. Taking the production of battery electrodes as an example, the accuracy of the feeding position directly affects the uniformity of electrode distribution inside the battery, thereby affecting the battery's performance and lifespan. The application of the feeding limit sensor 33 ensures feeding quality from the source, laying a solid foundation for producing high-performance, high-quality battery products.

[0092] The loading limit sensor 33 and the unloading limit sensor 34 work together to form a complete and efficient loading and unloading position detection and control system. By detecting the position of the limit plate 31 in real time and accurately, they provide precise feedback to the equipment's control system, enabling the system to adjust the movement of the telescopic mechanism 32 in a timely manner according to the actual situation, thus achieving precise control of the loading and unloading process. This intelligent control method not only improves the automation level of the equipment, reduces manual intervention, and lowers the labor intensity of operators, but also greatly improves production efficiency and product quality stability.

[0093] Meanwhile, the application of these two sensors also enhances the reliability and safety of the equipment. During the loading and unloading process, any positional deviation may lead to equipment malfunction or product quality issues. The loading limit sensor 33 and the unloading limit sensor 34 can promptly detect and correct these deviations, avoiding potential risks. For example, when the telescopic mechanism 32 malfunctions, causing the limit plate 31 to move abnormally, the sensors can quickly detect the abnormal signal and trigger the equipment's protection mechanism to stop the relevant operations, preventing further damage to the equipment and ensuring the safe operation of the production process.

[0094] In summary, in this embodiment, the loading and unloading auxiliary mechanism 3 achieves precise perception and intelligent control of the loading and unloading process by adding a loading limit sensor 33 and an unloading limit sensor 34.

[0095] Please refer to this again. Figure 1-2 and in conjunction with references Figure 4-6 In one embodiment of this invention, the main body component 2 is a key component with complete functions and complex structure. It cleverly integrates two core sub-mechanisms, the winding and unwinding mechanism 21 and the correction mechanism 22, which work together to ensure the efficiency and accuracy of the equipment in the process of processing materials.

[0096] The winding and unwinding mechanism 21 occupies a core position in the main body component 2, undertaking the important tasks of carrying the material and realizing the winding and unwinding operations of the material.

[0097] The correction mechanism 22 is a crucial component of the main body 2, ensuring the accuracy of material transmission. Its main function is to monitor and correct lateral offset of the material during transmission in real time. During the unwinding and winding of the material, various factors, such as the material's inherent unevenness, equipment installation errors, and external vibrations, can easily cause lateral offset. If this offset is not corrected in time, it will lead to problems such as uneven edges and misaligned winding in subsequent processing, seriously affecting product quality and production efficiency.

[0098] In summary, in the main body component 2 of this embodiment, the winding / unwinding mechanism 21 and the web-correcting mechanism 22 cooperate and complement each other, jointly forming a powerful and stable material handling system. The winding / unwinding mechanism 21 achieves efficient material loading, winding, and unwinding, while the web-correcting mechanism 22 ensures accurate positioning of the material during transmission. The two work together to provide strong support for the normal operation of the equipment and the high-quality production of products.

[0099] Understandably, the limiting plate 31 provides a large-stroke coarse adjustment for the position of materials of different widths. By abutting against the ends of materials of different widths, it provides a general positioning range for the materials, ensuring that there is no significant positional deviation during loading and unloading. The correction mechanism 22 further provides a small-stroke fine adjustment for the material's position. During material transport, the correction mechanism 22 can monitor minute offsets in real time and correct the material's position to the correct location through precise adjustment. This combination of coarse and fine adjustment allows for precise positioning and loading of materials of different widths, offering good applicability and ensuring that the materials maintain an accurate position throughout the production process, thereby improving product quality and production efficiency. For example, in the production of battery electrodes, the positional accuracy requirements during material winding are extremely high. The combination of the coarse adjustment of the limiting plate 31 and the fine adjustment of the correction mechanism 22 can meet the high-precision requirements of production, resulting in high-quality battery electrodes.

[0100] Please refer to this again. Figure 4-6 In one embodiment of this example, the winding and unwinding mechanism 21 is the core functional module of the main body component 2. It is ingeniously designed and has a reasonable structure. It is mainly composed of two key parts: the drive component 211 and the air shaft 212. The two work closely together to achieve efficient winding and unwinding of the material.

[0101] The drive assembly 211, as the power source of the winding and unwinding mechanism 21, bears the important responsibility of providing rotational power to the air shaft 212. In terms of structural composition, it typically includes core components such as a high-performance drive motor, a precision reducer, and a reliable coupling.

[0102] As the core power output unit of the entire drive system, the drive motor is an advanced type of motor with high power density, high efficiency, and good speed regulation performance. For example, in some production scenarios with high requirements for winding and unwinding speed and precision, servo motors may be used. Servo motors can precisely control their own speed and torque according to the instructions issued by the control system, achieving stepless speed regulation, thereby meeting the diverse needs of different material specifications and different production stages for winding and unwinding speed. At the same time, their high-precision position control capability also ensures accurate control of material tension during winding and unwinding, avoiding problems such as stretching, deformation, or wrinkling of the material due to excessive tension fluctuations.

[0103] The speed reducer is located between the drive motor and the air shaft 212, primarily serving to reduce speed and increase torque. By appropriately selecting the reduction ratio of the speed reducer, the high-speed, low-torque output from the drive motor can be converted into a low-speed, high-torque suitable for the rotation of the air shaft 212, thus providing sufficient power for the air shaft 212 to drive the material for winding or unwinding operations. Furthermore, the speed reducer also features excellent transmission smoothness and reliability, effectively reducing vibration and noise during transmission, and improving the stability and service life of the entire drive system.

[0104] As a key component connecting the output shaft of the drive motor and the input shaft of the reducer, as well as the output shaft of the reducer and the air expansion shaft 212, the coupling plays a crucial role. It not only accurately transmits torque but also compensates for axial, radial, and angular misalignments caused by installation errors, thermal deformation during equipment operation, and other factors, ensuring coaxiality between the drive motor, reducer, and air expansion shaft 212, and guaranteeing the smoothness and accuracy of power transmission. Furthermore, couplings are typically made of high-strength, wear-resistant materials, possessing sufficient load-bearing capacity and fatigue resistance, maintaining stable performance during long-term operation, and reducing equipment failures and downtime caused by coupling damage.

[0105] In actual operation, the drive end of the drive assembly 211 is securely connected to the air shaft 212 via a coupling. When a winding operation is required, the control system sends a command to the drive motor, which then rotates at a preset speed and torque. The power is transmitted to the air shaft 212 via a reducer, causing it to rotate and gradually wind the material onto the air shaft 212. During unwinding, the drive motor rotates in the opposite direction, allowing the air shaft 212 to smoothly release the material. This precise drive control capability of the drive assembly 211 provides a solid guarantee for the efficient and stable winding and unwinding operation of the winding and unwinding mechanism 21.

[0106] As a key component in the winding and unwinding mechanism 21 that directly carries the material, the air shaft 212 is ingeniously designed and possesses many unique functional advantages. In terms of appearance and structure, the air shaft 212 is usually a hollow shaft with multiple expandable keyways or air bladder structures distributed on its surface.

[0107] In terms of material support, the air shaft 212, through its special structural design, provides stable and reliable support for the material. When the material needs to be wound onto the air shaft 212, firstly, one end of the material is fixed to the surface of the air shaft 212, and then compressed air is injected into the air shaft 212. As the compressed air enters, the keyways or air bladders on the surface of the air shaft 212 gradually expand, tightly adhering to the inner surface of the material, thereby generating sufficient friction to firmly fix the material onto the air shaft 212. This fixing method is not only simple and quick to operate, but also adaptable to materials of different widths and thicknesses, and has wide applicability.

[0108] During the winding and unwinding process, the inflation and deflation characteristics of the air shaft 212 play a crucial role. During loading, the air shaft 212 is in an inflated state, and its close contact with the material ensures that the material is wound evenly and tightly onto the shaft, preventing loosening or slippage during winding and thus guaranteeing the quality and stability of the roll. During unloading, when the material needs to be released from the air shaft 212, the compressed air inside the air shaft 212 is simply expelled, causing the keyways or air bladders on its surface to contract, reducing friction with the material. The material can then be smoothly pushed off the air shaft 212 by the loading / unloading auxiliary mechanism 3. This method of fixing and releasing the material through inflation and deflation greatly improves the efficiency and convenience of the winding and unwinding operation, reducing manual intervention and operation time.

[0109] Furthermore, the air shaft 212 also possesses excellent sealing and pressure resistance. Its internal air passage system and sealing structure are meticulously designed to effectively prevent compressed air leakage, ensuring that the air shaft 212 maintains a stable expansion state during prolonged winding and unwinding processes, providing reliable fixing force for the material. Simultaneously, the shaft body and keyway of the air shaft 212 are typically made of high-strength metal materials, possessing sufficient pressure resistance to withstand significant tension, adapting to the winding and unwinding requirements of materials with varying strengths.

[0110] The drive assembly 211 and the air shaft 212 cooperate and work together in the winding and unwinding mechanism 21 to complete the winding, unwinding, and loading / unloading tasks of the material. Before the work begins, the material to be wound or unwound is prepared, and the air shaft 212 is adjusted to the deflated and contracted state. At this time, the key strip or air bladder on the surface of the air shaft 212 contracts, making it easy to fix one end of the material to the air shaft 212.

[0111] During the feeding operation, the material is first fed onto the air expansion shaft 212, and then compressed air is injected into the air expansion shaft 212, causing it to expand and firmly secure the material. Next, for winding, the drive assembly 211 is activated. The drive motor drives the air expansion shaft 212 to rotate via a reducer and coupling, and the material gradually winds around the shaft under the rotation of the air expansion shaft 212. During the winding process, the control system monitors and adjusts the speed and torque of the drive assembly 211 and the tension of the air expansion shaft 212 in real time according to preset parameters to ensure that the material can be wound or unwound evenly and tightly, forming a high-quality coil. Unwinding follows the same principle.

[0112] When the material is being unloaded, the compressed air inside the air shaft 212 is first discharged, causing its surface to contract and reducing the friction between it and the inner surface of the material. Then, the loading and unloading auxiliary mechanism 3 is activated to push the material off the air shaft 212.

[0113] In summary, in the winding and unwinding mechanism 21 of this embodiment, the drive assembly 211 and the air shaft 212, through their unique functions and close cooperation, achieve efficient and stable winding and unwinding of materials, as well as loading and unloading operations. This design not only improves production efficiency and reduces labor intensity, but also ensures the quality stability of materials during the winding and unwinding process, providing a strong guarantee for the smooth operation of the entire production process.

[0114] Please refer to this again. Figure 4-6 In one embodiment of this invention, the correction mechanism 22, as the core module ensuring accurate material transmission, is ingeniously designed and rationally structured. It is mainly composed of several key parts: a correction sensor 221, a correction follow-up roller 222, a correction actuator 223, and a connecting fixing plate 224. These components cooperate closely to construct an efficient and reliable material correction system, ensuring the straightness and stability of the material during transmission.

[0115] The web-alignment sensor 221 plays a crucial "detection pioneer" role in the entire web-alignment mechanism 22. Like a pair of keen eyes, it monitors in real-time and accurately whether the material has shifted laterally. In terms of working principle, the web-alignment sensor 221 typically employs advanced photoelectric detection technology or ultrasonic detection technology. Taking photoelectric detection technology as an example, it uses a transmitter and receiver inside the sensor. The transmitter emits a beam of light towards the edge of the material. When the material is in its normal transmission position, the light is reflected or blocked by the edge in a specific way, and the receiver receives a stable light signal. However, once the material shifts laterally, the relative position between the edge of the material and the transmitter changes, causing a change in the reflected or blocked light state, and the intensity or duration of the light signal received by the receiver also changes accordingly. The intelligent circuit inside the web-alignment sensor 221 quickly analyzes and processes these changes, converting them into electrical signals. These electrical signals contain key information such as the direction and amount of material shift, and then transmit this information to the subsequent control system, providing accurate data for the web-alignment operation.

[0116] The installation position of the web guiding sensor 221 is carefully designed, typically placed at critical nodes in the material transport path to maximize the detection of material offset. Furthermore, it possesses high-precision detection capabilities and a fast response speed, rapidly detecting changes in material offset instantaneously and promptly sending signals to ensure timely initiation of the web guiding operation, preventing serious problems in material transport caused by accumulated offset. For example, in some electronic component production lines with extremely high product precision requirements, the web guiding sensor 221 can detect material offset at the micron level, providing strong support for the production of high-quality products.

[0117] The tracking roller 222 is a key component in the tracking mechanism 22, providing stable support and guidance for the material. It plays an indispensable role in the material tracking process. Structurally, the tracking roller 222 typically consists of a high-precision roller, wear-resistant bearings, and a robust support frame. The roller surface undergoes fine machining, possessing extremely high flatness and smoothness, which reduces friction between the material and the roller, ensuring smooth sliding of the material during transport and preventing scratches or wear on the material surface due to excessive friction.

[0118] As the core rotating component of the tracking roller 222, the bearing is a high-performance rolling or sliding bearing, characterized by low friction, high precision, and long service life. It ensures that the roller can rotate flexibly and stably under material tension, without jamming or wobbling, thus providing continuous and stable support for the material. The bracket is used to fix the tracking roller 222 to the connecting plate 224. Its structure is rationally designed, possessing sufficient strength and rigidity to withstand various forces and vibrations generated during material transmission, ensuring that the tracking roller 222 always maintains a stable working state.

[0119] During the material alignment process, the alignment follower roller 222 adjusts accordingly based on the material's deviation. When the alignment sensor 221 detects a lateral shift in the material, the alignment actuator 223 drives the connecting fixing plate 224 to move laterally, and the alignment follower roller 222 moves along with it. During this movement, the alignment follower roller 222 provides new support points and guiding directions for the material through contact, guiding it back to its normal transport track. Simultaneously, the alignment follower roller 222 automatically adjusts its rotation based on the material's tension and transport speed, ensuring the material maintains stable tension throughout the alignment process and preventing issues such as material slack or overstretching, thus guaranteeing the accuracy and stability of the alignment effect.

[0120] The correction actuator 223 is the core power component in the correction mechanism 22 that realizes the lateral correction of the material. It is closely connected to the connecting and fixing plate 224 and can provide a powerful and precise driving force when correction is needed, driving the connecting and fixing plate 224 to move laterally as a whole, thereby correcting the lateral deviation of the material.

[0121] In actual operation, the correction actuator 223 reacts rapidly under the command of the control system based on the material offset information transmitted by the correction sensor 221. When a material offset in a certain direction is detected, the correction actuator 223 calculates the required distance and direction of movement according to a preset correction algorithm, and then drives the connecting fixed plate 224 to move in the opposite direction, causing the correction follower roller 222 to bring the material back to its normal position. The rapid response and precise driving capability of the correction actuator 223 ensure that the correction mechanism 22 can effectively correct the material offset in the shortest possible time, improving production efficiency and product quality.

[0122] The connecting fixing plate 224 serves as the mounting carrier for the various components in the web guiding mechanism 22, playing a crucial role in integrating and fixing key components such as the web guiding sensor 221, the web guiding follower roller 222, the drive assembly 211, and the air shaft 212. It is typically made of high-strength metal materials, such as aluminum alloy or stainless steel, possessing sufficient strength and rigidity to withstand the weight of each component and the various forces and vibrations generated during material transport, ensuring the stability of the entire web guiding mechanism 22 during operation.

[0123] The design of the connecting fixing plate 224 fully considers the installation position and interrelationship of each component. Through reasonable layout and precise processing, the relative position accuracy between components such as the correction sensor 221 and the correction follower roller 222 is guaranteed.

[0124] During the alignment process, the connecting plate 224, acting as the driving object of the alignment actuator 223, can move laterally as a whole under the action of the alignment actuator 223. To ensure the smoothness and accuracy of the movement of the connecting plate 224, guide rails or sliders are usually installed between it and the equipment frame. These guide devices can limit the direction of movement of the connecting plate 224, reduce friction and shaking during movement, and ensure that the connecting plate 224 can move accurately along the predetermined trajectory, thereby achieving accurate alignment of the material.

[0125] In summary, in the correction mechanism 22 of this embodiment, the correction sensor 221, the correction follow-up roller 222, the correction actuator 223, and the connecting fixing plate 224, through their unique functions and close cooperation, realize the real-time detection and precise correction of the lateral deviation of the material.

[0126] Please refer to this again. Figure 1-2 In one embodiment of this invention, in addition to the key components mentioned above, the main body component 2 also cleverly incorporates two important modules: a tape-joining platform 23 and a take-up / unwinding roller 24. These components complement the overall structure, jointly constructing an efficient and stable material handling system that plays an indispensable role in key stages such as material take-up / unwinding and tape joining.

[0127] The take-up and unwinding roller 24 plays a crucial role in providing stable support and precise guidance throughout the entire material take-up and unwinding process, ensuring that the material can complete the take-up and unwinding operations smoothly and stably.

[0128] The tape receiving platform 23 is located between the take-up / unwind roller 24 and the tracking roller 222, and is an important area for handling special situations such as tape breakage and material changes. Its design fully considers the ease of operation and efficiency in actual production, providing workers with a spacious and stable working space.

[0129] In actual production, when a belt breakage occurs or a material replacement is needed, the operator first places one end of the broken belt or the new material on the receiving platform 23. Then, based on the material composition and splicing requirements, a suitable splicing method is selected, such as using adhesive tape or hot-melt splicing, to splice the broken belt or new material with the material being transported. During the splicing process, the stable support and precise positioning of the receiving platform 23 provide excellent operating conditions for the operator, ensuring splicing quality. After splicing is completed, the operator only needs to start the equipment, and the material will continue to be smoothly transported under the guidance of the take-up and untake-down rollers 24 and the follow-up rollers 222, entering the subsequent processing steps. The entire production process can be quickly resumed, reducing production downtime caused by belt breakage or material replacement and improving production efficiency.

[0130] In summary, in the main body component 2 of this embodiment, the tape receiving platform 23 and the take-up and unwinding roller 24 provide an efficient and reliable solution for the take-up and unwinding of materials and the replacement of broken tapes through their unique functions and close cooperation with the surrounding components.

[0131] Please refer to this again. Figure 1-2 In one embodiment of this invention, the main body component 2 further includes an ultrasonic ranging sensor 25;

[0132] The ultrasonic ranging sensor 25 is used to collect data on the winding or unwinding length of the material in real time.

[0133] It should be noted that the ultrasonic ranging sensor 25 is a high-tech device that measures distance based on the characteristics of ultrasonic waves. It cleverly utilizes the physical principle of ultrasonic waves propagating in the air to achieve accurate measurement of the winding or unwinding length of materials.

[0134] The ultrasonic ranging sensor 25 can collect real-time data on the winding or unwinding length of materials and promptly feed this data back to the equipment's control system. The control system can monitor and precisely control the production process in real time based on preset production parameters, such as winding length and unwinding length. When the winding or unwinding length of the material reaches the preset value, the control system can automatically issue a command to stop the winding or unwinding operation, ensuring the accuracy and consistency of the production process. For example, on some electronic component production lines, the winding length of materials requires very precise control. The ultrasonic ranging sensor 25 can monitor the winding length in real time and immediately stop winding once the set value is reached, avoiding any impact on product quality due to excessively long or short winding lengths.

[0135] In summary, in the main body component 2 of this embodiment, the ultrasonic ranging sensor 25, with its precise measurement capabilities and close collaboration with other components, provides real-time and accurate data support for the winding and unwinding process of materials, effectively improving the automation level and quality control level of the production process.
