Abstract
Description
Technical Field
[0001] This application relates to the field of coating technology, and more particularly to a coating steel roller assembly and coating equipment. Background Technology
[0002] In the production of battery cells (especially lithium-ion batteries), the coating steel roller is one of the core components of the coating equipment. It is mainly used to uniformly coat the slurry (such as positive or negative electrode slurry) onto the substrate (such as copper foil or aluminum foil). During the coating process, the coating steel roller may become dirty, which will affect the coating effect. In this case, it may be necessary for the operator to wipe it manually.
[0003] Because the steel roller is clamped by a rotating rubber roller, there is a significant risk that the operator's fingers could get caught between the rotating rollers, posing a considerable safety hazard. During normal production, the coating equipment operates at a high speed. If foreign matter is found on the steel roller, production must be stopped and the speed reduced until the roller is completely cleaned before resuming high-speed production. This process severely impacts production efficiency and reduces capacity. Due to limited space, operators must reach into narrow gaps to access every part of the steel roller until it is completely clean. This operation is not only time-consuming and labor-intensive but also increases the difficulty of operation. During manual wiping, foreign matter removed may fall onto the electrode below, causing product quality issues and increasing quality risks.
[0004] Therefore, existing steel rollers do not have self-cleaning capabilities, and there is an urgent need for a coating steel roller assembly with cleaning capabilities to enable self-cleaning when needed, thereby achieving better coating results and ensuring product quality. Utility Model Content
[0005] This application provides a coating steel roller assembly to solve the problem of dirt appearing on the steel roller during the coating process, which affects the coating quality. It enables self-cleaning when needed, ensures the surface smoothness of the steel roller, achieves better coating effect, and ensures product quality.
[0006] In a first aspect, this application provides a coating steel roller assembly, comprising: a steel roller for supporting and conveying slurry during coating; a cleaning blade disposed behind the steel roller, the cleaning blade having a first side and a second side, the first side being fixed and the second side being used to scrape off foreign matter adhering to the surface of the steel roller; a driving device for driving the cleaning blade, causing the cleaning blade to move from a first state to a second state, wherein the first state of the cleaning blade is a state in which the second side is away from the steel roller, and the second state is a state in which the second side is in contact with the surface of the steel roller; and a waste trough disposed below the steel roller, the width of which extends from the location of the cleaning blade to the location of the steel roller, for collecting dirt and waste scraped off the surface of the steel roller.
[0007] Through the above scheme, the drive unit can switch the cleaning blade between the first and second states. This automated design allows the cleaning blade to quickly enter the working state (second state, scraping away foreign objects) when needed, and remain in the first state when not needed, without interfering with the normal operation of the steel roller. Compared to manual cleaning of the steel roller, this automated cleaning method greatly improves production efficiency, reduces downtime, and enables continuous and stable coating production. The waste trough effectively collects dirt and waste scraped from the surface of the steel roller. This prevents scraped waste from scattering around the equipment, causing problems such as difficulty in cleaning or even affecting the normal operation of the equipment, such as clogging other parts of the equipment or causing surface contamination. Collecting waste through the waste trough keeps the equipment clean and also helps maintain the working environment of the coating workshop, preventing waste from polluting the environment. The cleaning blade can promptly remove foreign objects from the surface of the steel roller, preventing foreign objects from adhering to the surface of the steel roller for a long time and causing accelerated wear. This ensures coating effect and product quality. These designs all help extend the service life of the steel roller and the entire coating equipment, and reduce equipment maintenance and replacement costs.
[0008] In one possible design, the second side is the cutting edge, which is wedge-shaped and the surface near the steel roller is inclined.
[0009] Through the above-described design, the wedge-shaped cutting edge has a sharp edge, enabling more effective scraping of foreign matter adhering to the steel roller surface, including slurry residue, impurities, or dirt. Compared to ordinary flat scrapers, this design can reach deeper into the tiny grooves or uneven areas of the steel roller surface, thus removing the adhering substances more thoroughly. The beveled design allows the cutting edge to act on the foreign matter with a smaller contact area and greater local pressure when contacting the steel roller surface, further improving scraping efficiency. Simultaneously, the bevel can guide the scraped waste material smoothly to the waste trough, preventing waste accumulation at the contact point between the scraper and the steel roller. When scraping foreign matter, the contact point of the wedge-shaped cutting edge is relatively concentrated, reducing the overall friction area between the scraper and the steel roller surface. This design not only reduces the wear rate of the scraper but also reduces the risk of scratching the steel roller surface, thereby extending the service life of both the scraper and the steel roller. The beveled design also provides a certain buffering effect when the scraper contacts the steel roller, making the contact between the scraper and the steel roller more stable and further reducing damage caused by hard contact. This cleaning scraper with its wedge-shaped blade and beveled design not only improves scraping efficiency and waste collection efficiency, but also reduces equipment wear and maintenance costs, further enhancing the overall performance and reliability of the coating steel roller assembly.
[0010] In one possible design, a reset device is also included, which drives the cleaning scraper to reset to the first state.
[0011] The above-described solution incorporates a reset device that allows the cleaning scraper to automatically return to its initial position (first state) after completing its scraping task. This automated design reduces the need for manual intervention, enabling the equipment to operate more efficiently, especially in continuous production, minimizing downtime and potential errors caused by manual operation. The reset device works in conjunction with the drive device to automatically switch the cleaning scraper between the first and second states. This collaborative operation makes the equipment run more smoothly, further improving production efficiency. When the cleaning scraper returns to the first state, the second side (blade tip) of the scraper is away from the steel roller surface, preventing unnecessary contact and friction between the scraper and the steel roller when not in operation. Reducing this ineffective contact effectively reduces wear on both the scraper and the steel roller, thereby extending their service life.
[0012] In one possible design, a support profile is also included, on which a fixed shaft is provided, and the first side is rotatably fixed on the fixed shaft; the drive device and the steel roller are both fixed on the support profile.
[0013] Through the above scheme, the support profile acts as a unified frame, integrating the cleaning blade, drive unit, and steel roller into a compact and stable system. This integrated design reduces relative displacement and loosening between components, improving the overall stability of the equipment. Since all key components are fixed to the same support profile, installation and maintenance become more convenient. Maintenance personnel can more quickly locate and replace parts, reducing repair time and costs. The first side of the cleaning blade is rotatably fixed to the support profile via a fixed shaft; this design ensures the accuracy and stability of the blade during movement. The fixed shaft provides a stable pivot point for the blade, allowing it to move smoothly and accurately when switching from the first to the second state. The rigid structure of the support profile and the precise design of the fixed shaft effectively reduce potential wobbling or deviation of the blade during movement, ensuring that the blade always accurately contacts the steel roller surface, improving cleaning effectiveness.
[0014] In one possible design, the drive unit is a cylinder, which is located on the side of the cleaning scraper away from the steel roller, and is used to push the cleaning scraper to rotate along a fixed axis under the push of the cylinder.
[0015] Through the above scheme, the cylinder, as a common drive device, can provide stable and adjustable power. By controlling the cylinder's air pressure and stroke, the movement speed and position of the cleaning blade can be precisely controlled, thus achieving a smooth switch from the first state to the second state. The cylinder's power output can be adjusted according to actual needs. For example, when cleaning thicker slurry residue, the air pressure can be increased to provide greater thrust; when cleaning thinner dirt, the air pressure can be reduced to avoid damage to the steel roller surface. This adjustability allows the equipment to adapt to different coating conditions. The cylinder has a simple structure, small size, and is easy to install. Placing it on the side of the cleaning blade away from the steel roller not only saves space but also avoids interference with the coating process. The cylinder's movement is relatively simple, mainly relying on air pressure to drive the piston, reducing complex transmission and wear between mechanical parts. Compared to other drive methods (such as motor drive), the cylinder has a longer service life and lower maintenance costs. The cylinder can complete its extension and retraction movements in a short time, thus quickly pushing the cleaning blade from the first state to the second state, or from the second state back to the first state. This rapid response capability is particularly suitable for continuous coating processes, significantly improving equipment operating efficiency. The quick action capability greatly reduces downtime during cleaning blade switching, further enhancing production efficiency.
[0016] In one possible design, a foreign object detection device is also included to detect foreign object information on the surface of the steel roll.
[0017] Through the above-described scheme, the foreign object detection device can monitor the presence of foreign objects on the steel roller surface in real time. By accurately detecting the location, size, and distribution of foreign objects, the cleaning blade can perform targeted cleaning according to actual needs. The detection device helps determine the optimal working state and position of the cleaning blade, avoiding unnecessary cleaning actions and thus improving cleaning efficiency. Combined with the foreign object detection device, the coating steel roller assembly can achieve automated cleaning. For example, when foreign objects are detected on the steel roller surface, the system can automatically activate the cleaning blade to clean; after cleaning, the detection device re-inspects the steel roller surface to confirm the cleaning effect. This automated control method reduces manual intervention, lowers the labor intensity of operators, and improves the operating efficiency of the equipment.
[0018] In one possible design, the foreign object detection device includes a sensor and a signal processing unit. The sensor is used to acquire images or reflected signals from the surface of the steel roll, and the signal processing unit is used to analyze the images or reflected signals and determine the foreign object information.
[0019] Through the above scheme, the sensor is used to acquire high-definition images of the steel roller surface, enabling intuitive detection of the shape, size, and distribution of foreign objects, or acquisition of the location and three-dimensional data of foreign objects, thus achieving more comprehensive foreign object detection. When the signal processing unit detects the presence of foreign objects on the steel roller surface, it can automatically trigger the cleaning scraper to clean, without manual intervention. After cleaning, the sensor can re-inspect the steel roller surface to verify the cleaning effect and ensure that foreign objects are completely removed. By introducing a foreign object detection device with sensors and a signal processing unit, the coating steel roller assembly can achieve intelligent and precise cleaning control.
[0020] In one possible design, an adjustment device is also included, which receives foreign object information and adjusts the cylinder's output pressure based on the foreign object information.
[0021] In the above-described scheme, the regulating device receives foreign object information from a foreign object detection device (such as a sensor and signal processing unit), analyzes the type, size, and degree of adhesion of the foreign object, and thus dynamically adjusts the cylinder's output pressure. The regulating device typically controls the cylinder's output pressure through a pressure regulating valve. The pressure regulating valve controls the gas pressure entering the cylinder by adjusting the position of the valve core. Operators can manually adjust the pressure regulating valve settings based on feedback from the foreign object detection device. Another approach integrates the regulating device with the foreign object detection device, automatically controlling the pressure regulating valve through a signal processing unit to achieve dynamic adjustment of the cylinder's output pressure. By dynamically adjusting the cylinder's output pressure, the cleaning scraper can more accurately remove different types of foreign objects, improving cleaning efficiency.
[0022] In one possible design, the fixed shaft is set parallel to the steel roller.
[0023] With the above design, the fixed shaft is arranged parallel to the steel roller, ensuring that the cleaning blade maintains uniform contact with the steel roller surface as it rotates along the fixed shaft under the push of the cylinder. This design guarantees that the blade maintains a consistent angle and pressure on the steel roller surface throughout the entire movement, thereby improving cleaning effectiveness and preventing incomplete cleaning or damage to the steel roller surface due to unstable contact. The parallel arrangement of the fixed shaft allows the cleaning blade to apply scraping force evenly during movement, avoiding excessive or insufficient local pressure due to angle changes, further enhancing the uniformity and reliability of cleaning. The parallel arrangement of the fixed shaft and steel roller reduces the risk of equipment failure due to unstable movement trajectories, such as preventing accidental collisions between the blade and the steel roller or other components, thus improving equipment reliability. Because the cleaning blade's movement trajectory is stable and predictable, the equipment has a higher degree of automation, reducing the frequency of manual adjustments and further improving production efficiency.

[0041] Coating rollers play a crucial role in battery cell production. Their core function is to uniformly and precisely coat the slurry onto the substrate, thereby forming high-quality electrodes. Figure 1 This is a schematic diagram of a coating steel roller provided in the prior art. Please refer to it. Figure 1 In existing technologies, the steel roller 100 works in conjunction with the rubber roller 110 and the material trough 120 to coat the substrate 200. If foreign matter appears on the surface of the steel roller 100 during coating, the machine must be stopped and the coating speed reduced. Then, the operator must manually wipe the surface of the steel roller 100. This process poses safety risks and affects production efficiency. These problems may negatively impact coating quality and cell performance.
[0042] In view of this, embodiments of this application provide a coating steel roller 100 assembly and a coating device, comprising: a steel roller 100 for supporting and conveying slurry during the coating process; a cleaning blade 300 disposed behind the steel roller 100, the cleaning blade 300 having a first side 310 and a second side 320, the first side 310 being fixed, and the second side 320 being used to scrape off foreign matter adhering to the surface of the steel roller 100; a driving device 400 for driving the cleaning blade 300, causing the cleaning blade 300 to move from a first state to a second state, wherein the first state of the cleaning blade 300 is a state in which the second side 320 is away from the steel roller 100, and the second state is a state in which the second side 320 is in contact with the surface of the steel roller 100; and a waste trough 500 disposed below the steel roller 100, and the width of the waste trough 500 extending from the location of the cleaning blade 300 to the location of the steel roller 100, for collecting dirt and waste scraped off the surface of the steel roller 100. It can self-clean when dirt occurs during the coating process of steel roller 100, ensuring the surface smoothness of steel roller 100, and will not generate waste that affects the equipment and coating workshop environment, thus ensuring better coating effect and improving product yield.
[0043] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.
[0044] Figure 2 This is a schematic diagram of the cleaning scraper 300 in the first state of the coating steel roller 100 assembly provided in this embodiment. Figure 3 This is a schematic diagram of the cleaning blade 300 in the second state of the coating steel roller 100 assembly provided in this embodiment. Please refer to... Figure 2 and Figure 3 The coating steel roller 100 assembly provided in this application includes a steel roller 100, a cleaning scraper 300, a drive device 400, and a waste trough 500.
[0045] The steel roller 100 serves as the support roller of the coating machine, carrying and transporting the substrate 200 (such as copper or aluminum foil) to ensure its flatness and stability during coating. After being unwound from the unwinding device, the substrate 200 passes over the surface of the steel roller 100, which rotates to move the substrate 200 forward. The surface of the steel roller 100 is precision-machined to be smooth and flat, preventing wrinkles or deformation of the substrate 200 during transport.
[0046] like Figure 2 and Figure 3 As shown, a back roller (or rubber roller 110) is provided at a corresponding position below or to the side of the steel roller 100. The rubber roller 110 can be arranged parallel to the steel roller 100. The steel roller 100 and the rubber roller 110 cooperate, and by adjusting the gap and pressure between them, the tension of the substrate 200 can be kept stable during the coating process. The steel roller 100 transfers the slurry from the slurry tank 120 to the surface of the substrate 200 through contact with the slurry, thereby achieving uniform coating of the slurry.
[0047] like Figure 2 and Figure 3 As shown, a slurry tank 120 is provided below or to the side of the steel roller 100, near the immersion portion of the steel roller 100. The slurry tank 120 is used to store slurry and transfers the slurry to the surface of the substrate 200 by the rotation of the steel roller 100. A substrate 200 transfer system can also be provided at the front or rear end of the steel roller 100. The substrate 200 transfer system operates synchronously with the steel roller 100 to ensure that the substrate 200 can be transferred smoothly during the coating process.
[0048] like Figure 2 and Figure 3 As shown, in this embodiment, the coating steel roller 100 assembly is used in the coating of the second side of the substrate 200. That is, the first side 201 of the substrate 200 has been coated, and the second side of the substrate 200 is being coated. The uncoated portion 203 of the second side is below the steel roller 100, and the coated portion 202 of the second side is above the steel roller 100.
[0049] like Figure 2 and Figure 3As shown, in this embodiment, the cleaning blade 300 is disposed behind the steel roller 100, meaning the side facing away from the substrate 200. The cleaning blade 300 has a first side 310 and a second side 320. The first side 310 is fixed, and the second side 320 is used to scrape off foreign matter adhering to the surface of the steel roller 100. The cleaning blade 300 can promptly remove foreign matter from the surface of the steel roller 100, preventing foreign matter from adhering to the surface of the steel roller 100 for a long time, which would lead to accelerated wear on the surface of the steel roller 100. This ensures the coating effect and product quality.
[0050] The drive unit 400 drives the cleaning blade 300, causing it to switch between a first state and a second state. In the first state, the second side 320 of the cleaning blade 300 is away from the steel roller 100; in the second state, the second side 320 is in contact with the surface of the steel roller 100. The drive unit 400 can switch the cleaning blade 300 between these two states. This automated design allows the cleaning blade 300 to quickly enter the working state (second state, scraping away foreign matter) when needed, and remain in the first state when not needed, without interfering with the normal operation of the steel roller 100. Compared to manual cleaning of the steel roller 100, this automated cleaning method significantly improves production efficiency, reduces downtime, and enables continuous and stable coating production.
[0051] In this embodiment, the waste trough 500 is directly fixed below the steel roller 100, and its width extends from the location of the cleaning scraper 300 to the location of the steel roller 100. It collects dirt and waste scraped from the surface of the steel roller 100 without requiring additional control or drive, resulting in a simpler overall structure. The waste trough 500 effectively collects dirt and waste scraped from the surface of the steel roller 100. This prevents scraped waste from scattering around the equipment, causing difficulties in cleaning and potentially affecting normal operation, such as clogging other parts or contaminating the equipment surface. Collecting waste through the waste trough 500 keeps the equipment clean and also helps maintain the working environment of the coating workshop, preventing waste from polluting the environment.
[0052] Through the above scheme, the design of the entire coating steel roller 100 assembly takes into account functions such as cleaning and waste collection, making the equipment more stable and reliable during operation. The switching of the cleaning blade 300 and the coordinated use of the waste trough 500 reduce the risk of equipment failure caused by foreign objects and waste, improve the stability of equipment operation, make the coating production process smoother, and reduce production interruptions and increased defect rates caused by equipment failures. This helps to extend the service life of the steel roller 100 and the entire coating equipment, and reduce equipment maintenance and replacement costs.
[0053] Please refer to Figure 2 and Figure 3In this embodiment, the second side 320 is the blade end, which is wedge-shaped and the surface near the steel roller 100 is an inclined surface.
[0054] Through the above-described design, the wedge-shaped cutting edge has a sharp edge, enabling more effective scraping of foreign matter adhering to the surface of the steel roller 100, including slurry residue, impurities, or dirt. Compared to ordinary flat scrapers, this design can reach deeper into the tiny grooves or uneven areas of the steel roller 100 surface, thus removing the adhering substances more thoroughly. The beveled design allows the cutting edge to act on the foreign matter with a smaller contact area and greater local pressure when contacting the surface of the steel roller 100, further improving scraping efficiency. At the same time, the bevel can also guide the scraped waste material smoothly to the waste trough 500, preventing waste material from accumulating at the contact point between the scraper and the steel roller 100. When scraping foreign matter, the contact point of the wedge-shaped cutting edge is relatively concentrated, which can reduce the overall friction area between the scraper and the surface of the steel roller 100. This design not only reduces the wear rate of the scraper but also reduces the risk of scratching the surface of the steel roller 100, thereby extending the service life of the scraper and the steel roller 100. The beveled design provides a buffer when the scraper contacts the steel roller 100, resulting in a smoother contact and further reducing damage caused by hard contact. This wedge-shaped blade and beveled design of the cleaning scraper 300 not only improves scraping efficiency and waste collection efficiency but also reduces equipment wear and maintenance costs, further enhancing the overall performance and reliability of the coating steel roller 100 assembly.
[0055] In this embodiment, a reset device (not shown) is also included, which drives the cleaning scraper 300 to reset to the first state.
[0056] The reset device can be a spring connected between the cleaning scraper 300 and the support profile, which enables the cleaning scraper 300 to automatically return to its initial position (first state) after completing the scraping task.
[0057] This automated design reduces the need for manual intervention, allowing the equipment to operate more efficiently, especially in continuous production, reducing downtime and potential errors caused by manual operation. The reset device, working in conjunction with the drive unit 400, enables the cleaning scraper 300 to automatically switch between the first and second states. This collaborative operation makes the equipment run more smoothly, further improving production efficiency. When the cleaning scraper 300 resets to the first state, the second side 320 (blade tip) of the scraper moves away from the surface of the steel roller 100, preventing unnecessary contact and friction between the scraper and the steel roller 100 when not in operation. Reducing this ineffective contact effectively reduces wear on both the scraper and the steel roller 100, thereby extending their service life.
[0058] In this embodiment, the coating steel roller 100 assembly also includes a support profile, on which a fixed shaft is provided, and the first side 310 is rotatably fixed on the fixed shaft.
[0059] Through the above scheme, the support profile, as an integral frame, integrates the cleaning scraper 300, drive unit 400, and steel roller 100 into a compact and stable system. This integrated design reduces relative displacement and loosening between components, improving the overall stability of the equipment. Since all key components are fixed to the same support profile, installation and maintenance become more convenient. Maintenance personnel can more quickly locate and replace parts, reducing repair time and costs. The first side 310 of the cleaning scraper 300 is rotatably fixed to the support profile via a fixed shaft. This design ensures the accuracy and stability of the scraper during movement. The fixed shaft provides a stable pivot point for the scraper, allowing it to move smoothly and accurately when switching from the first state to the second state. The rigid structure of the support profile and the precise design of the fixed shaft effectively reduce potential wobbling or deviation of the scraper during movement, ensuring that the scraper always accurately contacts the surface of the steel roller 100, improving the cleaning effect.
[0060] Both the drive unit 400 and the steel roller 100 can be fixed to the support profile. Fixing the drive unit 400 and the steel roller 100 to the support profile ensures that these components will not loosen or shift during operation. This design reduces the risk of equipment failure due to component loosening, improving the reliability of equipment operation. Furthermore, the centralized fixing of all components to the support profile allows maintenance personnel to perform inspections and repairs more quickly, reducing maintenance workload and lowering equipment maintenance costs.
[0061] In this embodiment, the fixed shaft is arranged parallel to the steel roller 100. This parallel arrangement ensures that the cleaning scraper 300 maintains uniform contact with the surface of the steel roller 100 as it rotates along the fixed shaft under the push of the cylinder. This design guarantees that the scraper maintains a consistent angle and pressure on the surface of the steel roller 100 throughout the entire movement, thereby improving the cleaning effect and preventing incomplete cleaning or damage to the surface of the steel roller 100 due to unstable contact.
[0062] The parallel arrangement of the fixed shafts allows the cleaning scraper 300 to apply scraping force evenly during movement, avoiding excessive or insufficient local pressure due to angle changes, thus further improving the uniformity and reliability of cleaning. The parallel arrangement of the fixed shafts and the steel roller 100 reduces the risk of equipment failure due to unstable movement trajectories, such as preventing accidental collisions between the scraper and the steel roller 100 or other components, thereby improving equipment reliability. Because the movement trajectory of the cleaning scraper 300 is stable and predictable, the equipment has a higher degree of automation, reducing the frequency of manual adjustments and further improving production efficiency.
[0063] In this embodiment, the driving device 400 is a cylinder, which is located on the side of the cleaning scraper 300 away from the steel roller 100. The cylinder is used to push the cleaning scraper 300, and the cleaning scraper 300 rotates along a fixed axis under the push of the cylinder.
[0064] A cylinder, as a common drive device 400, provides stable and adjustable power. By controlling the cylinder's air pressure and stroke, the movement speed and position of the cleaning blade 300 can be precisely controlled, thus achieving a smooth transition from the first state to the second state. The cylinder's power output can be adjusted according to actual needs. For example, when cleaning thicker slurry residue, the air pressure can be increased to provide greater thrust; when cleaning thinner dirt, the air pressure can be reduced to avoid damage to the surface of the steel roller 100. This adjustability allows the equipment to adapt to different coating conditions. Furthermore, the cylinder has a simple structure, small size, and is easy to install. Placing it on the side of the cleaning blade 300 away from the steel roller 100 not only saves space but also avoids interference with the coating process. The cylinder's movement is relatively simple, mainly relying on air pressure to drive the piston, reducing complex transmission and wear between mechanical parts. Compared to other drive methods (such as motor drive), the cylinder has a longer service life and lower maintenance costs. The cylinder can extend and retract in a short time, quickly switching the cleaning blade 300 from the first state to the second state, or back to the first state. This rapid response capability is particularly suitable for continuous coating processes, significantly improving equipment operating efficiency. The rapid action also greatly reduces downtime during cleaning blade 300 state switching, further enhancing production efficiency.
[0065] In some embodiments, the coating steel roller 100 assembly further includes a foreign matter detection device for detecting foreign matter information on the surface of the steel roller 100.
[0066] Through the above-described scheme, the foreign object detection device can monitor the surface of the steel roller 100 for foreign objects in real time. By accurately detecting the location, size, and distribution of foreign objects, the cleaning blade 300 can perform targeted cleaning according to actual needs. The detection device helps determine the optimal working state and position of the cleaning blade 300, avoiding unnecessary cleaning actions and thus improving cleaning efficiency. Combined with the foreign object detection device, the coating steel roller 100 assembly can achieve automated cleaning. For example, when foreign objects are detected on the surface of the steel roller 100, the system can automatically start the cleaning blade 300 to clean it; after cleaning, the detection device checks the surface of the steel roller 100 again to confirm the cleaning effect. This automated control method reduces manual intervention, lowers the labor intensity of operators, and improves the operating efficiency of the equipment.
[0067] In some embodiments, the foreign object detection device includes a sensor and a signal processing unit. The sensor is used to acquire images or reflected signals from the surface of the steel roller 100, and the signal processing unit is used to analyze the images or reflected signals and determine foreign object information.
[0068] The sensor can be an image sensor, such as a camera, which can acquire high-definition images of the surface of the steel roller 100, and can intuitively detect the shape, size and distribution of foreign objects.
[0069] The sensor can also be a lidar or millimeter-wave radar, which can emit laser or millimeter-wave signals and receive reflected signals to obtain the location and three-dimensional data of foreign objects, thereby enabling more comprehensive detection of foreign objects.
[0070] The signal processing unit analyzes the images or reflected signals acquired by the sensors and determines foreign object information, improving the accuracy and reliability of detection. When the signal processing unit detects foreign objects on the surface of the steel roller 100, it automatically triggers the cleaning scraper 300 to clean it without manual intervention. After cleaning, the sensor can re-detect the surface of the steel roller 100 to verify the cleaning effect and ensure that the foreign objects are completely removed. By introducing a foreign object detection device with sensors and a signal processing unit, the coating steel roller 100 assembly can achieve intelligent and precise cleaning control.
[0071] In some embodiments, the system further includes an adjustment device for receiving foreign object information and adjusting the output pressure of the cylinder according to the foreign object information.
[0072] Through the above scheme, the regulating device receives foreign object information provided by the foreign object detection device (such as a sensor and a signal processing unit), analyzes the type, size and degree of adhesion of the foreign object, and thus dynamically adjusts the output pressure of the cylinder. The regulating device usually controls the output pressure of the cylinder through a pressure regulating valve.
[0073] The pressure regulating valve controls the gas pressure entering the cylinder by adjusting the position of the valve core. The operator can manually adjust the pressure regulating valve settings based on feedback from the foreign object detection device. For example, in this embodiment, the output pressure of the cylinder can be controlled between 0.2 MPa and 0.5 MPa by manually adjusting the pressure regulating valve based on information about foreign objects on the surface of the steel roller 100.
[0074] In some other embodiments, the adjustment device can be integrated with the foreign object detection device, and the pressure regulating valve can be automatically controlled by the signal processing unit to achieve dynamic adjustment of the cylinder output pressure. By dynamically adjusting the cylinder output pressure, the cleaning scraper 300 can more accurately remove different types of foreign objects and improve cleaning efficiency.
