Description

Technical Field

[0001] This application relates to the field of laser technology, and in particular to a system and method for removing oxide layers from roller surfaces using lasers. Background Technology

[0002] Currently, the global production process for electrolytic copper foil employs a continuous roller electrolysis method. This method offers advantages such as simplicity, high automation, and the ability to maintain continuous production. The principle involves depositing and reducing copper ions from a copper sulfate solution onto the surface of a titanium-based cathode roller that rotates at a constant speed under an applied electric field. Then, through continuous electrodeposition and the constantly rotating cathode roller, copper foil of a certain thickness is peeled off from the roller surface and wound up. However, due to the high acid concentration of the copper sulfate solution, the complex composition of organic additives, and the high temperature, the surface of the titanium-based cathode roller oxidizes rapidly. Furthermore, titanium oxide, as a semiconductor material, has significantly lower conductivity compared to titanium. When the oxide layer on the roller surface is too thick, the copper ion electrodeposition process is hindered, leading to foil powdering and a decrease in copper foil quality. In severe cases, it can increase electrode polarization, raise the cell voltage, dramatically increase heat generation, and raise energy consumption.

[0003] Current technologies typically employ mechanical polishing, using a composite material of 1000-mesh or higher nylon and micro / nano-sized zirconia particles. Online polishing is achieved by controlling the lateral swing amplitude and polishing pressure. This method is limited by the operator's experience, is inefficient, and can lead to uneven oxide layer removal, potentially damaging the cathode roller in severe cases. Summary of the Invention

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0022] Examples of embodiments in this application, such as Figures 1-3 As shown, a system for removing oxide layers from roller surfaces based on laser technology is provided. The system includes: a motion device 100, a laser device 200, an image acquisition device 300, a fluorescence analysis device 400, and a control device 500. The motion device 100 is equipped with the laser device 200, the image acquisition device 300, and the fluorescence analysis device 400. The motion device 100 drives the laser device 200, the image acquisition device 300, and the fluorescence analysis device 400 to move along the length of the roller 600. The laser device 200 generates a laser beam to remove the oxide layer in the target area of ​​the roller surface. The image acquisition device 300 acquires structural data of the target area of ​​the roller surface. The fluorescence analysis device 400 acquires oxide data of the target area of ​​the roller surface. The control device 500 is connected to the motion device 100, the laser device 200, and the fluorescence analysis device 400. The device 200, image acquisition device 300, and fluorescence analysis device 400 are connected to control the motion device 100 to move the laser device 200, image acquisition device 300, and fluorescence analysis device 400 along the length of the roller 600 according to the cleaning command input by the user. The device controls the laser device 200 to remove the oxide layer on the roller surface, controls the image acquisition device 300 to acquire structural data, and controls the fluorescence analysis device 400 to acquire oxide data. Based on the structural data and oxide data, it determines whether the oxide layer removal on the roller surface is complete. If not, it continues to control the laser device to remove the oxide layer on the roller surface, control the image acquisition device to acquire structural data, and control the fluorescence analysis device to acquire oxide data, and determines whether the oxide layer removal on the roller surface is complete based on the structural data and oxide data, until the oxide layer on the roller surface is completely removed.

[0023] Specifically, the motion device 100 includes a motor, a horizontal guide rail, and a loading platform. The motor can be a servo motor. For example, the loading platform is mounted on the horizontal guide rail, and a gear is mounted on the loading platform. Correspondingly, a rack is mounted within the horizontal guide rail, with the rack's length direction aligned with the length direction of the horizontal guide rail. The motor is mounted on the loading platform and connected to the gear drive. The gear meshes with the rack, and the motor drives the gear to rotate, thereby moving the loading platform. It is understood that the above description of the motion device 100 is merely illustrative. The loading platform can also be controlled by a motor driving a lead screw, etc., as long as the loading platform can move on the horizontal guide rail. This embodiment does not specifically limit the driving method.

[0024] The laser device 200, image acquisition device 300, and fluorescence analysis device 400 are all mounted on the platform. That is, the image acquisition device 300 and the fluorescence analysis device 400 can be mounted separately or simultaneously. For example, the platform can house both the laser device 200 and the image acquisition device 300; it can also house both the laser device 200 and the fluorescence analysis device 400; or it can simultaneously house the laser device 200, the image acquisition device 300, and the fluorescence analysis device 400. The following example illustrates the simultaneous mounting of the image acquisition device 300 and the fluorescence analysis device 400. The laser device 200 is a device capable of generating a laser beam; preferably, the output power of the laser device 200 is adjustable. The image acquisition device 300 can acquire structural data of the external environment, including image or waveform data. If the structural data is an image, the image acquisition device includes two cameras. By acquiring images of the same area from both cameras, depth information is calculated using the parallax between the two images. Based on the depth information of each pixel, it is determined whether the oxide layer in the current area has been completely removed. If the structural data is waveform data, the waveform data is the light signal reflected from the roller surface acquired by the image acquisition device 300, which is then converted into an electrical signal. Based on the waveform data, it is determined whether the oxide layer in the current area has been completely removed. The fluorescence analysis device 400 can acquire oxide data on the object surface, i.e., oxide content. Based on the oxide content, it is determined whether the oxide layer in the current area has been completely removed. In this system, the fluorescence analysis device 400 generates X-rays and bombards the roller surface with them. Upon receiving the X-rays, the inner-shell electrons of the elements on the roller surface are ejected, causing transitions in their outer electrons. When these transitioned electrons return to their ground state, they generate characteristic X-rays associated with the element. Different elements produce different characteristic X-rays, which have different energies or wavelengths. The fluorescence analysis device 400 receives and analyzes these characteristic X-rays to determine the oxide content of the roller surface. The laser beam irradiation area of ​​the laser device 200, the image acquisition area of ​​the image acquisition device 300, and the data acquisition area of ​​the fluorescence analysis device 400 are matched. For example, the image acquisition area and the data acquisition area may include the irradiation area, thereby determining whether the oxide layer in the current area has been completely removed based on the acquired structural and oxide data.For example, the fluorescence analysis device 400 is mounted on a platform, the laser device 200 is mounted on the fluorescence analysis device 400, and the image acquisition device 300 is mounted on the laser device 200. That is, the image acquisition device 300, laser device 200, and fluorescence analysis device 400 are arranged sequentially from top to bottom on the platform. Alternatively, the image acquisition device 300 can be mounted on the platform, the laser device 200 on the platform, and the fluorescence analysis device 400 on the platform. The embodiments of this application do not specifically limit the placement of the image acquisition device 300, laser device 200, and fluorescence analysis device 400, as long as they are all mounted on the platform.

[0025] The horizontal guide rail of the motion device 100 is set in the same direction as the length direction of the roller 600. That is, the horizontal guide rail is set parallel to the roller 600. In this way, when the platform moves on the horizontal guide rail, it can drive the laser device 200 to remove oxides from all areas of the roller 600, and enable the image acquisition device 300 and the fluorescence analysis device 400 to acquire data from all areas of the roller 600.

[0026] The control device 500 can be any device with data processing capabilities, such as a CPU, microcontroller, computer equipment, or server. The control device 500 can receive cleaning commands input by the user. It can be connected to external devices such as a keyboard, mouse, or remote control. The user sends cleaning commands to the control device 500 through these external devices. Upon receiving the commands, the control device 500 controls the motion device 100 to move the laser device 200, image acquisition device 300, and fluorescence analysis device 400 along the horizontal guide rail. Simultaneously, it controls the laser device 200 to activate, generating a laser beam that irradiates the roller surface, thereby removing the oxide layer. Simultaneously, it controls the image acquisition device 300 to activate, acquiring image or waveform data of the roller surface, and simultaneously controls the fluorescence analysis device 400 to activate, acquiring oxide data of the roller surface. By simultaneously acquiring structural and oxide data through the image acquisition device 300 and the fluorescence analysis device 400, it determines whether the oxide layer has been completely removed.

[0027] Based on the structural data and oxide data, it is determined whether the oxide layer on the roller surface has been completely removed. If not, the laser device continues to remove the oxide layer, the image acquisition device acquires waveform data, and the fluorescence analysis device acquires oxide data. Based on the waveform data and oxide data, it is determined whether the oxide layer on the roller surface has been completely removed, until the oxide layer on the roller surface is completely removed. For example, determining whether the oxide layer on the roller surface has been completely removed based on at least one of the structural data and oxide data can be done based on only the structural data, only the oxide data, or both simultaneously. When it is determined that the oxide layer has been completely removed, the cleaning process ends. If the oxide layer has not been completely removed, the laser device continues to remove the oxide layer on the roller surface, and the image acquisition device acquires waveform data and the fluorescence analysis device acquires oxide data simultaneously. Then, based on the waveform data and oxide data, it is determined whether the oxide layer on the roller surface has been completely removed. If not, the oxide layer removal process is repeated until the oxide layer on the roller surface is completely removed.

[0028] The aforementioned system for removing oxide layers from roller surfaces using laser technology includes: a motion device, a laser device 200, an image acquisition device 300, a fluorescence analysis device 400, and a control device 500. The motion device is equipped with the laser device 200, the image acquisition device 300, and the fluorescence analysis device 400. The motion device drives the laser device 200, the image acquisition device 300, and the fluorescence analysis device 400 to move along the length of the roller 600. The laser device 200 generates a laser beam to remove the oxide layer from the target area of ​​the roller surface. The image acquisition device 300 acquires the structure of the target area of ​​the roller surface. The system includes a structural data acquisition device; a fluorescence analysis device 400 for acquiring oxide data of the target area on the roller surface; and a control device 500 connected to a motion device, a laser device 200, an image acquisition device 300, and a fluorescence analysis device 400. Based on user-input cleaning commands, the control device 500 moves the laser device 200, the image acquisition device 300, and the fluorescence analysis device 400 along the length of the roller 600, and controls the laser device 200 to remove the oxide layer on the roller surface, the image acquisition device 300 to acquire structural data, and the fluorescence analysis device 400 to acquire oxide data. By automating oxide layer removal with the laser device 200, efficiency is improved, and the real-time data feedback from the image acquisition device 300 and the fluorescence analysis device 400 enhances the accuracy of oxide layer removal, thereby preventing damage to the cathode roller.

[0029] In one embodiment, the system for removing the oxide layer on the roller surface using laser further includes a distance detection device. The distance detection device is mounted on the motion device 100 or at the endpoint and is connected to the control device 500. It is used to detect the distance between the motion device 100 and the endpoint. The control device 500 is also used to: pre-set a starting point and an endpoint, which are sequentially arranged along the length of the roller 600; acquire cleaning commands input by the user and distance information detected by the distance detection device; control the motion device 100 to continuously move from the starting point to the endpoint; and synchronously control... The laser device 200 generates a laser beam to remove the oxide layer on the roller surface, and simultaneously controls the image acquisition device 300 and the fluorescence analysis device 400 to acquire structural data and oxide data of the roller surface; based on the structural data and oxide data, it is determined whether the oxide layer removal on the roller surface is complete; if not, the motion device 100 is controlled to move continuously from the starting position to the ending position again, and the laser device 200 is simultaneously controlled to generate a laser beam to remove the oxide layer on the roller surface, and the image acquisition device 300 and the fluorescence analysis device 400 are simultaneously controlled to acquire structural data and oxide data of the roller surface; until the oxide layer removal is completed.

[0030] Specifically, this embodiment may also include a distance detection device, which can be a photoelectric sensor. The photoelectric sensor includes a transmitter and a receiver. When the photoelectric sensor is placed on the platform, a reflective element is placed at the corresponding endpoint. The transmitter generates a beam of light, which is reflected by the reflective element and received by the receiver. The distance between the platform and the endpoint is then determined based on the electrical signal received by the receiver. Alternatively, when the photoelectric sensor is placed at the endpoint, the transmitter generates a beam of light, which is reflected by the platform and received by the receiver. The distance between the platform and the endpoint is then determined based on the electrical signal received by the receiver. This embodiment does not specifically limit the location of the distance detection device; it only needs to be able to detect the distance between the platform and the endpoint.

[0031] Before cleaning the roller 600, first set the start and end points. For example, as shown... Figure 4 As shown, the length information of roller 600 can be obtained first. Based on the length of roller 600, the start and end points can be set, meaning the two endpoints of roller 600 along its length need to be positioned between the start and end points. The start and end points are set along the length of the horizontal guide rail. The start and end points represent the positions on the horizontal guide rail.

[0032] After the control device 500 receives the cleaning command input by the user, it synchronously controls the motion device 100 to continuously move the laser device 200, image acquisition device 300, and fluorescence analysis device 400 from the starting point to the ending point. That is, the motion device 100 moves continuously along the horizontal guide rail from the starting point to the ending point without stopping. During the movement, the laser device 200 generates a laser beam to remove the oxide layer on the roller surface, and the image acquisition device 300 and fluorescence analysis device 400 acquire structural and oxide data of the roller surface. During the laser cleaning of the roller 600, the cathode roller operates independently, meaning it is always rotating. When the distance detection device detects that the platform has moved to the ending point, it controls the platform to stop moving and stops the laser device 200, image acquisition device 300, and fluorescence analysis device 400 from operating.

[0033] After the first round of oxide removal is completed, the system determines whether oxide removal on the roller surface is complete based on the structural data acquired by the image acquisition device 300 and the oxide data acquired by the fluorescence analysis device 400. For example, the thickness difference before and after oxide removal is determined based on the structural data; a first cleanliness parameter is determined based on the thickness difference and a thickness threshold; a second cleanliness parameter is determined based on the oxide data and the oxide threshold; and the current area is judged to have completed oxide removal based on the first and second cleanliness parameters. The image acquisition device 300 can acquire structural data of the external environment, including image or waveform data. If the structural data is an image, the image acquisition device includes two cameras. By acquiring images of the same area from both cameras, depth information is calculated using the parallax between the two images. The thickness difference before and after oxide removal is determined by calculating the depth information before and after oxide removal. If the structural data is waveform data... The waveform data refers to the waveform data obtained by the image acquisition device 300 after acquiring the light signal reflected from the roller surface and converting it into an electrical signal. The thickness difference before and after oxide layer removal is determined based on the waveform data before and after oxide layer removal. The thickness threshold is the thickness of the oxide layer to be removed, which can be set according to actual needs. Subtracting the thickness threshold from the thickness difference yields the first cleaning parameter. The oxide threshold is the oxide threshold that the roller surface needs to reach after oxide layer removal, which can also be set according to actual needs. Subtracting the oxide threshold from the oxide data yields the second cleaning parameter. The first cleaning parameter alone can be used to determine whether oxide layer removal is complete in the current area. For example, if the first cleaning parameter is less than zero, oxide removal is not complete; if the first cleaning parameter is greater than or equal to zero, oxide removal is complete. Similarly, the second cleaning parameter alone can be used to determine whether oxide layer removal is complete in the current area. For example, if the second cleaning parameter is greater than zero, oxide removal is not complete; if the first cleaning parameter is less than or equal to zero, oxide removal is complete. Alternatively, both the first and second cleaning parameters can be considered to determine whether oxide layer removal is complete in the current area. For example, the first and second cleaning parameters can be normalized and then weighted and averaged. The average value can be compared with zero to determine whether the oxide layer removal is complete.

[0034] If the oxide layer removal is incomplete, the motion device 100 can be controlled to move from the starting position to the ending position. The laser device 200 can then be controlled to generate a laser beam to remove the oxide layer from the roller surface. Simultaneously, the image acquisition device 300 and the fluorescence analysis device 400 are controlled to acquire structural data and oxide data of the roller surface. This process continues until the oxide removal is determined to be complete based on the structural and oxide data. In other words, if the second oxide layer removal is still incomplete, a third and fourth removal process is performed until the removal is complete.

[0035] In one embodiment, the system for removing the oxide layer on the roller surface based on laser also includes a distance detection device. The distance detection device is disposed on the motion device 100 or at the endpoint and is connected to the control device 500. It is used to detect the distance between the motion device 100 and the endpoint. The control device 500 is further configured to: pre-set a starting point, multiple cleaning points, and an endpoint, which are sequentially arranged along the length of the roller 600; acquire a cleaning command input by the user and control the motion device 100 to move to the starting point; and control the laser device 200 to generate a laser beam to remove the oxide layer in the target area of ​​the roller surface. Simultaneously, the image acquisition device 300 and the fluorescence analysis device 400 are controlled to acquire structural data and oxide data of the target area; based on the structural data and oxide data, it is determined whether the oxide layer removal of the current target area has been completed; if completed, the motion device 100 is controlled to move to the next cleaning point, and the laser device 200 is simultaneously controlled to generate a laser beam to remove the oxide layer on the roller surface, and the image acquisition device 300 and the fluorescence analysis device 400 are simultaneously controlled to acquire structural data and oxide data of the roller surface; until the motion device 100 moves to the endpoint position based on the distance information detected by the distance detection device.

[0036] Specifically, the distance detection device in this embodiment is set in the same location and has the same distance detection method as the distance detection device in the above embodiments. For details, please refer to the description of the distance detection device in other embodiments of this document, which will not be repeated here.

[0037] Before cleaning the roller 600, first set the start and end points. For example, as shown... Figure 4 As shown, the length information of roller 600 can be obtained first. Based on the length of roller 600, the starting point and ending point are set, meaning the two endpoints of roller 600 along its length need to be positioned between the starting point and the ending point. After determining the starting point and ending point, multiple cleaning points are set between them. The cleaning points can be determined based on the distribution of the oxide layer on roller 600. For example, if the oxide layer only exists in the middle of roller 600, no cleaning points are set in the area without an oxide layer, and multiple cleaning points are set in the area with an oxide layer. Cleaning points can also be set at equal intervals between the starting point and the ending point, ensuring that the cleaning areas of adjacent cleaning points on the roller surface are connected. The cleaning area is the target area where the laser device 200 generates a laser beam to remove the oxide layer from the roller surface. The starting point, multiple cleaning points, and the ending point are set sequentially along the length of the horizontal guide rail. The starting point, multiple cleaning points, and the ending point represent their positions on the horizontal guide rail.

[0038] After the control device 500 receives the cleaning command input by the user, it controls the motion device 100 to move to the starting position. For example, the distance information between the platform and the endpoint can be detected by a distance detection device, and the starting position can be determined based on this distance information. Once the motion device 100 reaches the starting position, it stops moving. The laser device 200 is controlled to generate a laser beam to remove the oxide layer in the target area of ​​the roller surface, and the image acquisition device 300 and the fluorescence analysis device 400 are simultaneously controlled to acquire the structural data and oxide data of the target area. The target area is the area irradiated by the laser beam on the roller surface when the laser device 200 is at the starting or cleaning point. Based on the structural data and oxide data of the target area, it is determined whether the oxide layer removal in the current target area is complete. For example, the thickness difference before and after oxide layer removal is determined based on the structural data; a first cleanliness parameter is determined based on the thickness difference and a thickness threshold; a second cleanliness parameter is determined based on the oxide data and an oxide threshold; and the oxide layer removal in the current area is determined based on the first and second cleanliness parameters. In this embodiment, the method for determining whether the oxide layer removal in the current area has been completed is the same as that in the above embodiments. For details, please refer to the methods for determining whether the oxide layer removal has been completed in other embodiments, which will not be repeated here.

[0039] If the oxide layer removal of the target area is determined to be complete, the motion device 100 is controlled to move to the next cleaning point. After the motion device 100 moves to the next cleaning point, the laser device 200 is controlled to generate a laser beam to remove the oxide layer on the roller surface, and the image acquisition device 300 and the fluorescence analysis device 400 are simultaneously controlled to acquire the structural data and oxide data of the roller surface. For example, after the oxide layer removal of the target area is completed at the previous cleaning point, the laser device 200, the image acquisition device 300, and the fluorescence analysis device 400 can be controlled to stop working first. After the motion device 100 moves to the next cleaning point, the laser device 200, the image acquisition device 300, and the fluorescence analysis device 400 can be controlled to start working again. Alternatively, after the oxide layer removal of the target area is completed at the previous cleaning point, the motion device 100 can move directly to the next cleaning point for cleaning, and the laser device 200, the image acquisition device 300, and the fluorescence analysis device 400 will not stop working during the movement. When the motion device 100 moves to the next cleaning point, the distance information between the loading platform and the endpoint can be detected by the distance detection device, and the motion device 100 can be determined to have moved to the next cleaning point based on the distance information.

[0040] The oxide layer is removed sequentially at the starting point and multiple cleaning points until the motion device 100 reaches the endpoint. After reaching the endpoint, the platform is stopped, and the laser device 200, image acquisition device 300, and fluorescence analysis device 400 are also stopped.

[0041] In one embodiment, if the oxide layer removal of the current target area is not completed, the laser device 200 is controlled to generate a laser beam to remove the oxide layer of the target area of ​​the roller surface again based on the initial power, and the image acquisition device 300 and the fluorescence analysis device 400 are simultaneously controlled to acquire the structural data and oxide data of the target area; until the oxide layer removal of the current target area is completed; the power information of the current target area when removing the oxide layer multiple times is acquired; based on the power information of the multiple oxide layer removals, the initial power of the laser device 200 is adjusted when the target area oxide layer is removed at the next cleaning point.

[0042] Specifically, when the motion device 100 stops at the starting point or a certain cleaning point, the roller 600 rotates. After the roller 600 completes one revolution, it determines whether the oxide layer removal of the current target area is complete based on the structural data and oxide data of the target area. If not, the laser device 200 generates a laser beam based on the initial power to remove the oxide layer from the target area again. The initial power is the power of the laser device 200 during the first cleaning of the current target area. The roller 600 rotates one revolution, completing the second cleaning. If the oxide layer removal of the current target area is complete at this time, the motion device 100 is controlled to move to the next cleaning point; if the current area is not yet complete, a third and fourth cleaning are performed until the oxide layer removal of the current target area is complete, and then the motion device 100 is controlled to move to the next cleaning point. After it is determined that the oxide layer removal of the current target area is complete, the power information of the current target area during the multiple oxide layer removals is obtained. For example, the current target area is cleaned twice, both times using the initial power. The sum of the power of the two cleanings is used as the initial power of the laser device 200 at the next cleaning point. For example, if the current target area is cleaned twice, and both times the initial power is used, then the two initial powers are added together, and the sum is used as the initial power of the laser device 200 at the next cleaning point.

[0043] In this embodiment, the cleaning efficiency can be further improved by adjusting the output power of the laser device 200 in real time.

[0044] In one embodiment, if the oxide layer removal of the current target area is not completed, the initial power of the laser device 200 is adjusted by a preset power threshold; based on the adjusted initial power, the laser device 200 is controlled to generate a laser beam to remove the oxide layer of the target area on the roller surface again, and the image acquisition device 300 and the fluorescence analysis device 400 are simultaneously controlled to acquire the structural data and oxide data of the target area; until the oxide layer removal of the current target area is completed; the power information of the current target area when removing the oxide layer multiple times is acquired; based on the power information of the multiple oxide layer removals, the initial power of the laser device 200 is adjusted when the target area oxide layer is removed at the next cleaning point.

[0045] Specifically, when the motion device 100 stops at the starting point or a certain cleaning point, the roller 600 rotates. After the roller 600 completes one revolution, it determines whether the oxide layer removal of the current target area has been completed based on the structural data and oxide data of the target area. If not, the initial power of the laser device 200 is adjusted, since the oxide layer removal of the current target area is not completed after one revolution of the roller 600 at the initial power. The output power of the laser device 200 can be increased. For example, each time the output power of the laser device 200 is increased, it can be increased according to a preset power threshold. This threshold can be set according to actual needs. It can be understood that the preset power can be preset to the minimum step size of the adjustable power of the laser device. For example, when adjusting the initial power of the laser device 200, the preset power threshold is added to the initial power to obtain the adjusted initial power. Then, a laser beam is generated using the adjusted initial power to remove the oxide layer from the target area again. The initial power is the power of the laser device 200 during the first cleaning of the current target area. Roller 600 rotates once, completing the second cleaning. If the oxide layer removal is complete in the current target area, the motion device 100 is moved to the next cleaning point. If the current area is not yet clean, a third and fourth cleaning are performed until the oxide layer removal is complete, at which point the motion device 100 moves to the next cleaning point. Once the oxide layer removal is confirmed, the power information of the multiple oxide layer removals in the current target area is obtained. For example, the current target area is cleaned twice; the first cleaning power is the initial power, and the second cleaning power is the adjusted initial power. The sum of the two cleaning power values ​​is used as the initial power of the laser device 200 at the next cleaning point. Alternatively, if the current target area is cleaned twice, with the first cleaning power being the initial power and the second cleaning power being the adjusted initial power, the initial power and the adjusted initial power are added together, and the sum is used as the initial power of the laser device 200 at the next cleaning point. Since the initial power of the laser device 200 at the next cleaning point is sufficient to remove the oxide layer on the roller surface, this initial power can be used to remove the oxide layer on the roller surface at subsequent cleaning points. This initial power can also ensure the cleaning effect and efficiency of the roller surface.

[0046] In this embodiment, the cleaning efficiency can be further improved by adjusting the output power of the laser device 200 in real time.

[0047] In one embodiment, a stop time for the laser device 200 is preset; after the motion device 100 moves to the starting position and controls the laser device 200 to generate a laser beam, the motion time of the motion device 100 is counted; if the motion time reaches the stop time, the laser device 200 is controlled to stop generating laser.

[0048] Specifically, to prevent the laser device 200 from remaining on after the motion device 100 reaches the endpoint, a stop time for the laser device 200 can be set. Since multiple cleaning points (with fixed laser spot overlap rate and spot area) are equally spaced, and the motion device 100 moves at the same speed, the time taken for the motion device 100 to move from one cleaning point to the next is equal. Therefore, based on the number of cleaning points and the spacing between them, the total time required for the motion device 100 to move during the entire cleaning process can be determined, and this time is used as the stop time. After the motion device 100 reaches the starting point, its movement time is recorded in real time. No time is counted when the motion device 100 reaches a cleaning point for cleaning; time is started when the motion device 100 moves from one point to the next. By comparing the real-time recorded movement time with the stop time, the laser device 200 is controlled to stop generating laser light when the stop time is reached.

[0049] In this embodiment, by setting a stop time, it can be further ensured that when the motion device 100 moves to the end position, the laser device 200 is controlled to stop generating laser, thus avoiding damage to the system due to the failure to shut down the laser beam.

[0050] In one embodiment, a zero-start position is preset; an initialization command input by the user is obtained, and the motion device 100 is controlled to move to the zero-start position.

[0051] Specifically, such as Figure 4 As shown, a zero-start position can also be preset, set in the direction away from the end position from the starting position. When the control device 500 receives the initialization command input by the user, it controls the motion device 100 to move to the zero-start position. For example, when the laser device 200 performs a complete cleaning cycle on the roller 600 and reaches the end position, if the roller 600 needs to be replaced, the replaced roller 600 needs to be cleaned; or the current roller 600 needs to be cleaned again. At this time, the user will input an initialization command, and after receiving the initialization, the control device 500 controls the motion device 100 to move to the zero-start position.

[0052] In one embodiment, the motion device includes a motor, a motor driver, a horizontal guide rail, and a carrying platform; the laser device includes a laser; the image acquisition device includes a CCD camera; and the fluorescence analysis device includes an online fluorescence analyzer. The carrying platform is mounted on the horizontal guide rail, and the motor and motor driver are mounted on the carrying platform. The remaining components on the motor can translate along the horizontal guide rail under the motor's drive. According to the operator's control, the control device generates a start signal and presets the zero position, starting position, ending position, and the motion speed of the motion device. During the actual cleaning of the rollers, the motion speed can be detected in real time, and compared with the preset motion speed to generate an adjustment command. This adjustment command controls the motor driver to adjust the real-time motion speed. The motor driver controls the motor operation according to the start signal and the adjustment command. During the cleaning process of the rollers, the control device can summarize and analyze the information (oxide content) collected by the CCD camera, laser power, laser spot shape, laser wavelength, laser repetition frequency, and the online fluorescence analyzer, and use the summarized and analyzed data to control the motor driver.

[0053] A CCD camera is positioned above the laser to collect and monitor data on the oxide layer on the cathode roller surface, specifically its thickness. The thickness of the oxide layer is monitored using a laser triangulation method.

[0054] An online fluorescence analyzer is placed below the laser to collect data on the treated area and boundary of the oxide layer. When calculating the oxide content, a quantitative evaluation method for the laser effect based on oxygen content is used.

[0055] During the cleaning process of the rollers, based on data collected by the CCD camera and the online fluorescence analyzer, it is determined whether the cleaning effect of the current area meets the expectations. When the expectations are met, the platform is controlled to move to the next section. Using data from the CCD camera, the online fluorescence analyzer, and constraints among multiple system parameters, a quantitative expression method and a multivariate high-order regression modeling method are employed to construct a multidimensional hypersurface response mathematical and physical model of the laser parameters, process control parameters, and cleaning effect. A weighted function synthesis and genetic factor algorithm are then used to solve for the optimal solution of the process control parameters, which is transmitted to the control device to control the system parameters and achieve the best cleaning effect.

[0056] For example, if the desired result is not achieved, the same section is processed again at the same laser power. Furthermore, when processing the next section of the cathode roller, the power is increased or processed multiple times at the same power. Simultaneously, oxide layer thickness data is fed back in real time for dynamic adjustments.

[0057] Taking the cleaning of titanium cathode rollers as an example, the laser power is a 300W nanosecond laser with a laser overlap rate of 70%, a scanning speed of 10mm / s, a cleaning width of 150mm, and a relative rotation speed of the cathode rollers of 1m / min. The control device also calculates data from the CCD camera and the online fluorescence analyzer. When the data from the two conflict, the data from the online fluorescence analyzer takes priority. The zero-start position is the position of the CCD camera, laser, and online fluorescence analyzer on the horizontal guide rail during system initialization. A zero-start photoelectric sensor can be set on the guide rail at the zero-start position. When the control device receives the initialization command, it generates an initialization control signal based on the command and sends it to the motor driver. The motor driver moves the motor towards the zero-start position according to the command. When the zero-start photoelectric sensor receives the instrument signal, it determines that the motor position has returned to zero. Alternatively, a starting position photoelectric sensor can be set at the starting point and an ending position photoelectric sensor can be set at the ending point. The motor driver controls the motor to move from the starting point to the ending point according to the cleaning command. When the starting position photoelectric sensor receives a signal from the instrument, it determines that the motor position has reached the starting position; when the ending position photoelectric sensor receives a signal from the instrument, it determines that the motor position has reached the ending position. The starting and ending positions can be set automatically according to the length of the roller.

[0058] The laser output power can be adjusted by changing the output power of the laser's power supply.

[0059] Multiple platforms can be installed on a horizontal guide rail, each equipped with a motion device, laser device, image acquisition device, and fluorescence analysis device. This further improves cleaning efficiency.

[0060] This embodiment of the application features fully automated control and intelligent feedback adjustment, resulting in high cleaning efficiency. It also reduces labor costs and improves cleaning accuracy. The increased cleaning accuracy further extends the service life of the rollers, enabling effective detection and processing of oxide layer thickness, thus ensuring the stability of copper foil production.
