[0025] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] One embodiment of the present invention provides a cleaning device for cleaning a target area of ​​a workpiece 200. The workpiece 200 can be a lithium-ion battery, and the target area is the electrolyte inlet of the lithium-ion battery. Figures 1 to 4 As shown, the cleaning device includes: an equipment support 110, an optical module, a drive mechanism, and a dust removal mechanism. The equipment support 110 is the supporting structure of the cleaning device, including a base plate and a structural support mounted on the base plate. The base plate is a flat plate structure, and the structural support is vertically fixedly mounted on the upper surface of the base plate to support and carry components such as the optical module and the drive mechanism. Both the optical module and the dust removal mechanism are movably mounted on the equipment support 110 via guide rail sliders. The optical module has image acquisition and laser emission functions to acquire image information of the target area, and to determine the actual position and morphological characteristics of the target area based on the acquired image information to perform laser cleaning on the target area. The dust removal mechanism is used to remove vaporized contaminants, detached particles, and splashed molten material generated during the laser cleaning process. The drive mechanism is connected to both the optical module and the dust removal mechanism. The drive mechanism is configured to drive the dust removal mechanism toward or away from the target area, and to drive the optical module to move based on the image information of the target area.

[0027] By acquiring image information of the target area through an optical module, and cooperating with the drive mechanism, laser cleaning is performed on the target area based on this image information, achieving automated cleaning and adapting to the cleaning needs of workpieces 200 of different specifications, thus improving the equipment's versatility. The drive mechanism moves the optical module based on the image information acquired by the optical module, achieving closed-loop position compensation. When there is a deviation in the incoming position of the workpiece 200, the system can automatically identify and correct the laser beam's irradiation position, ensuring that the laser scanning trajectory for each cleaning is precisely aligned with the geometric center of the target area. This avoids cleaning blind spots or laser damage to non-target areas of the workpiece 200 caused by positioning deviations. Simultaneously, the drive mechanism drives the dust removal mechanism to move towards or away from the target area to achieve automatic dust removal, ensuring the cleaning effect of the optical module.

[0028] In optional embodiments of the present invention, such as Figures 1 to 3 As shown, the optical module includes an image acquisition unit 120 and a laser cleaning unit 130. The image acquisition unit 120 and the laser cleaning unit 130 can be integrated into one unit or installed separately on the same mounting structure. The image acquisition unit 120 can be an industrial camera; the laser cleaning unit 130 includes a laser, a beam transmission optical path, and a galvanometer scanning and focusing system. The galvanometer scanning system controls the laser beam to perform rapid, full-coverage scanning of the target area in a spiral or grating path through a preset program; a long-focal-length deep-field lens is set on the light-emitting side of the galvanometer scanning system, utilizing its deep-focal characteristics to ensure that the conical surface and bottom of the injection port are within the effective depth of focus. Before the laser cleaning unit 130 performs the cleaning operation, the image acquisition unit 120 first takes pictures of the target area to obtain an image containing the position and orientation information of the target area. After the control unit processes the image using a template matching algorithm, it calculates the deviation between the actual center coordinates and the theoretical center coordinates of the target area, and converts this deviation into a motion compensation amount for the drive mechanism. This causes the drive mechanism to move the entire optical module horizontally and vertically to directly above the target area, achieving alignment between the laser beam emission position and the center of the target area. After the laser cleaning unit 130 completes the cleaning operation, the image acquisition unit 120 takes pictures of the same target area again to obtain a cleaned surface image. The control unit performs quantitative evaluation and qualification judgment of the cleaning effect by comparing and analyzing the images before and after cleaning or extracting the texture features of the cleaned image to ensure the cleaning effect.

[0029] In optional embodiments of the present invention, such as Figures 1 to 3As shown, the mounting bracket 140 is flat. The image acquisition unit 120 and the laser cleaning unit 130 are fixedly mounted on the mounting bracket 140 by screws, pins, or positioning clips. When the mounting bracket 140 is driven to move as a whole by the drive mechanism, the image acquisition unit 120 and the laser cleaning unit 130 on it move synchronously as a whole, and their relative positional relationship remains unchanged during the movement. Since both the image acquisition unit 120 and the laser cleaning unit 130 are fixed on the same mounting bracket 140 and driven to move synchronously by the same drive mechanism, their relative positional relationship remains constant during use, avoiding coordinate deviations caused by the accumulation of positioning errors from the two drive systems when the image acquisition unit 120 and the laser cleaning unit are driven separately.

[0030] In optional embodiments of the present invention, such as Figures 1 to 3 As shown, the drive mechanism includes a first drive assembly 151 and a second drive assembly 152. The first drive assembly 151 includes a first servo motor and a first ball screw pair. The first servo motor is fixedly mounted on the structural support, the screw of the first ball screw pair is connected to the output shaft of the first servo motor, and the nut of the first ball screw pair is fixedly connected to the base of the second drive assembly 152. The second drive assembly 152 is disposed on the nut of the first drive assembly 151. The second drive assembly 152 includes a second servo motor and a second ball screw pair. The second servo motor is fixedly mounted on the base of the second drive assembly 152, the screw of the second ball screw pair is connected to the output shaft of the second servo motor, and the nut of the second ball screw pair is fixedly connected to the mounting bracket 140. When the first servo motor of the first drive assembly 151 rotates, it drives the second drive assembly 152 and the mounting bracket 140 to move as a whole along the first direction via the first ball screw pair; when the second servo motor of the second drive assembly 152 rotates, it drives the mounting bracket 140 to move relative to the base of the second drive assembly 152 along the second direction via the second ball screw pair. The first direction and the second direction are perpendicular to each other in the vertical plane, specifically, the first direction is horizontal and the second direction is vertical; or the first direction is vertical and the second direction is horizontal.

[0031] The first drive component 151 and the second drive component 152 constitute a two-dimensional motion platform, enabling the optical module to achieve independent motion with two degrees of freedom in the vertical plane, ensuring that the laser acts uniformly on every position of the target area.

[0032] In optional embodiments of the present invention, such as Figures 1 to 4As shown, the dust removal mechanism includes a dust removal hood 161 and a compressed air nozzle 162; the dust removal hood 161 is hemispherical and can cover the target area; the dust removal hood 161 has an air inlet 163 and an air outlet 164 on its side, the compressed air nozzle 162 is located at the air inlet 163, and the air outlet direction of the compressed air nozzle 162 is tangential to the inner surface of the dust removal hood 161.

[0033] The dust collector hood 161 adopts a hemispherical shell structure. Both the bottom and top surfaces of the dust collector hood 161 are open, with the open ends facing each other to allow the laser to pass through. The bottom opening of the dust collector hood 161 faces the target area. When the dust collector hood 161 is lowered to the working position, its bottom opening surrounds the target area, completely enclosing the entire target area within the internal cavity of the dust collector hood 161. An air inlet 163 and an air outlet 164 are provided on the side of the dust collector hood 161. The compressed air nozzle 162 is a tubular or nozzle-shaped element, installed at the air inlet 163 and connected to an external compressed air source through a pipe joint. The center line of the air outlet 164 of the compressed air nozzle 162 is configured to be consistent with the tangential direction of the inner surface of the dust collector 161 at the air inlet 163. That is, the gas ejected from the compressed air nozzle 162 enters the cavity of the dust collector 161 along the tangential direction of the hemispherical inner wall at the air inlet 163.

[0034] The compressed air nozzle 162 is tangentially positioned to the inner surface of the dust collector hood 161, ensuring that the high-speed injected gas does not directly impact the target area surface, preventing the splashing and diffusion of pollutants or secondary adhesion of already detached particles. Instead, it forms a wall-attachment effect (i.e., the Coanda effect) along the hemispherical inner wall, causing the gas to flow along the inner wall and gradually change direction, creating an ordered spiral upward airflow field inside the dust collector hood 161. During use, the shearing force of the rotating airflow entrains and peels off loose particles and residual droplets from the target area surface, achieving non-contact physical pre-cleaning. In addition, during the laser cleaning process, the smoke and plasma plume generated by laser ablation are carried along a spiral path and transported to the outlet 164 for discharge, preventing secondary deposition of pollutants.

[0035] In optional embodiments of the present invention, such as Figures 1 to 4 As shown, the cleaning device also includes a workpiece pressure plate 170; the driving mechanism includes a third driving component 153, which is connected to the workpiece pressure plate 170 in a transmission manner. The third driving component 153 is used to drive the workpiece pressure plate 170 to move toward or away from the workpiece 200, so that the workpiece pressure plate 170 can press or release the workpiece 200; the workpiece pressure plate 170 is provided with an opening, and a dust removal hood 161 is fixedly installed on the workpiece pressure plate 170, and the dust removal hood 161 covers the opening.

[0036] The workpiece pressure plate 170 is a flat plate structure. An opening is provided on the workpiece pressure plate 170, extending through its upper and lower surfaces. The shape and size of the opening are adapted to the shape and size of the target area, allowing the laser beam to pass through and reach the target area. Simultaneously, the dust collector hood 161 communicates with the space above the target area through this opening. The drive mechanism also includes a third drive assembly 153, which can be a cylinder or a servo motor paired with a ball screw. The third drive assembly 153 drives the workpiece pressure plate 170 to move vertically toward or away from the workpiece 200. When the workpiece pressure plate 170 moves toward the workpiece 200 and contacts the surface of the workpiece 200, it applies pressure to press and fix the workpiece 200 onto the mounting fixture 180, preventing the workpiece 200 from shifting due to vibration or airflow impact during cleaning. After cleaning, the workpiece pressure plate 170 moves away from the workpiece 200, releasing the workpiece 200 so that it can be conveyed to the next process. A dust hood 161 is fixedly mounted on the upper surface of the workpiece pressure plate 170, with its opening surrounding the opening of the workpiece pressure plate 170, allowing the inner cavity of the dust hood 161 to communicate with the space above the target area through the opening of the workpiece pressure plate 170. The dust hood 161 and the workpiece pressure plate 170 can be fixed by screws, welding, or integrally cast. When the third drive assembly 153 drives the workpiece pressure plate 170 to rise and fall, the dust cover 161, being fixed on the workpiece pressure plate 170, rises and falls synchronously with the workpiece pressure plate 170.

[0037] The workpiece pressure plate 170 presses the workpiece 200 firmly during the cleaning process, effectively preventing the workpiece 200 from shifting position or vibrating under the influence of external forces such as laser cleaning and high-speed airflow impact. The dust hood 161 is fixed to the workpiece pressure plate 170 and rises and falls synchronously with the workpiece pressure plate 170. When the workpiece pressure plate 170 is driven to descend and press the workpiece 200, the dust hood 161 simultaneously descends into place and covers the target area. There is no need to set up a separate lifting drive mechanism for the dust hood 161, which simplifies the equipment structure and control logic and reduces manufacturing costs.

[0038] In an optional embodiment of the present invention, a sealing ring is provided around the outer edge of the opening of the workpiece pressure plate 170 away from the dust removal hood 161. When the third drive assembly 153 drives the workpiece pressure plate 170 to descend to the working position, the sealing ring is tightly fitted with the upper surface of the workpiece 200, forming an annular sealing band around the opening of the workpiece pressure plate 170. This isolates the target area corresponding to the opening of the workpiece pressure plate 170 from the external environment, effectively preventing toxic and harmful fumes and pollutants generated during the laser cleaning process from leaking outward from the gap between the workpiece pressure plate 170 and the surface of the workpiece 200. This avoids cross-contamination of the production environment and health hazards to operators, and also prevents dust and particulate matter in the external air from entering the inner cavity of the dust removal hood 161 and contaminating the cleaned surface.

[0039] In optional embodiments of the present invention, such as Figures 1 to 3 As shown, the cleaning apparatus also includes a mounting fixture 180 for fixing the workpiece 200. The mounting fixture 180 is used to fix the workpiece 200 to improve the stability of the workpiece 200 during laser cleaning and dust removal.

[0040] Another embodiment of the present invention provides a battery production line including the cleaning device in any of the above embodiments.

[0041] A third embodiment of the present invention also provides a cleaning method, which is based on the cleaning device in any of the above embodiments.

[0042] Cleaning methods include: Image information of the target area is acquired through an optical module; The optical module is moved based on image information via a drive mechanism. The dust removal mechanism is driven to move towards the target area by the drive mechanism; The target area is laser-cleaned using an optical module, and the target area is dust-removed by a dust removal mechanism during or after the laser cleaning process.

[0043] In this embodiment, the workpiece 200 is conveyed to the cleaning station by a conveyor line. After the positioning sensor detects that the workpiece 200 has arrived, it sends a positioning signal to the control system. Upon receiving the positioning signal, the control unit sends a collection command to the image acquisition unit 120 in the optical module. The image acquisition unit 120 captures an image of the target area (liquid injection port) on the workpiece 200, obtaining a high-resolution digital image containing the position and shape features of the target area, and transmits the image data to the image processing module of the control unit. Next, the image processing module of the control unit performs preprocessing, feature extraction, and template matching algorithms on the acquired image, calculates the positional deviation between the actual center coordinates of the target area and the preset theoretical coordinates, generates a position compensation command based on the positional deviation, and sends it to the first drive component 151 and the second drive component 152. Through the first drive component 151 and the second drive component 152, the laser emission axis of the laser cleaning unit 130 is precisely aligned with the center position of the target area. Subsequently, the control unit sends a clamping command to the third drive assembly 153, which drives the workpiece pressure plate 170 to move toward the workpiece 200, causing the workpiece pressure plate 170 to descend and clamp the workpiece 200. At the same time, the dust removal hood 161 fixed on the workpiece pressure plate 170 descends synchronously with the workpiece pressure plate 170. The dust removal hood 161 covers the target area, and the sealing ring fits against the surface of the workpiece 200 to form a sealed cavity. Before or at the same time as the workpiece pressure plate 170 descends, the control unit controls the negative pressure source of the dust removal mechanism to start in advance, so that a negative pressure environment is formed inside the dust removal hood 161. Next, the control unit sends a cleaning start command to the laser cleaning unit 130 according to the preset cleaning process parameters. The laser cleaning unit 130 emits a laser beam and controls the laser beam to scan the target area through the openings on the top and ground surfaces of the dust hood 161 and the opening of the workpiece pressure plate 170, following a preset spiral or grating scanning path via a galvanometer scanning system. During or after cleaning, compressed air nozzles 162 tangentially inject compressed air into the dust hood 161, forming a spiral upward airflow within the dust hood 161. This airflow entrains and carries the smoke and dust generated during laser cleaning and the detached contaminants to the air outlet 164, where it can be continuously extracted by a negative pressure source through a dust removal pipe. After laser cleaning is completed, the laser cleaning unit 130 stops emitting light, but the dust removal mechanism can continue to operate for a preset time to completely remove any remaining smoke and dust from the cavity. Afterward, the image acquisition unit 120 captures images of the cleaning effect again, and the control unit judges the cleaning quality based on these images.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
