Description

Technical Field

[0001] This application belongs to the field of battery production technology, and in particular relates to a laser cleaning device, a battery production line, and a battery electrode cleaning method. Background Technology

[0002] In battery manufacturing, laser cleaning of battery electrodes is a crucial step in ensuring product quality, involving precise treatment of the first and second sides of the electrodes. Due to the inherent uniformity fluctuations in the coating of the battery electrode material and the inconsistent dust removal efficiency of the dust removal system in the four directions, the cleaning parameters for the four edges of the battery electrode need to be set differently for each side. Specifically, the cleaning parameters for the first side cannot be directly applied to the second side, meaning that it is difficult to simultaneously meet the depth requirements of both sides at the same cleaning station.

[0003] However, most current laser cleaning equipment adopts a single-station design, which commonly results in the simultaneous processing of the first and second surfaces at the same station, leading to a serious lack of stability in cleaning depth. For example, when the cleaning depth of the first surface meets the standard, the second surface often fails to meet the standard, and vice versa, directly causing a decrease in product qualification rate. Summary of the Invention

[0004] The purpose of this application is to provide a laser cleaning device, a battery production line, and a battery electrode cleaning method that can stably distinguish between the first and second surfaces, avoid conflicts in cleaning parameters, and improve the stability of cleaning depth and product qualification rate.

[0005] To achieve the above objectives, according to a first aspect of the embodiments of this application, a laser cleaning apparatus is provided, including a movable stage structure, a detection mechanism, a laser cleaning mechanism, and a controller. The movable stage structure includes a slide rail assembly and a stage module disposed on the slide rail assembly. The stage module is reciprocating along the extension direction of the slide rail assembly. The slide rail assembly has a first station section, a second station section, and a third station section connected sequentially along its extension direction. When the stage module is located at the first station section, the product to be cleaned is placed on the stage module. The slide rail assembly includes multiple slide rails arranged side by side. The stage module includes multiple carrier plates, which are disposed one-to-one with the multiple slide rails. The surface of the product to be cleaned on at least one carrier plate is the first surface, and the surface of the product to be cleaned on the other carrier plates is the second surface. The detection mechanism is disposed corresponding to the second station section and is used to detect the product transferred to the second station section. The laser cleaning mechanism is disposed corresponding to the third station section and performs laser cleaning on the product transferred to the third station section. The stage module, the detection mechanism, and the laser cleaning mechanism are electrically connected to the controller.

[0006] The laser cleaning device provided in this application distinguishes between the first and second sides of the product by setting multiple slide rails and carrier plates. Combined with the detection and cleaning mechanism, it achieves stable cleaning, can stably distinguish between the first and second sides, avoids conflicting cleaning parameters, and improves the stability of cleaning depth and product qualification rate.

[0007] In some embodiments, the multiple slide rails include a first rail and a second rail, and the multiple carrier plates include a first carrier plate and a second carrier plate. The first carrier plate is disposed on the first rail, and the second carrier plate is disposed on the second rail. The surface of the product to be cleaned placed on the first carrier plate is the first surface, and the surface of the product to be cleaned placed on the second carrier plate is the second surface. By clearly defining the first rail and the second rail, as well as the corresponding first and second carrier plates, the laser cleaning device achieves the ability to process products with different surfaces to be cleaned in parallel. Products can be independently inspected by the detection mechanism on their respective carrier plates and then cleaned by the laser cleaning mechanism, significantly improving the overall working efficiency and production throughput of the laser cleaning device.

[0008] In some embodiments, the laser cleaning apparatus further includes a material platform structure and a gripping structure. The material platform structure has an intermittently spaced loading section and a unloading section. The loading section is used to detachably place a loading box, and the unloading section is used to detachably place an unloading box. A first station section is located between the loading section and the unloading section. A controller is electrically connected to the gripping structure, and the controller controls the gripping structure to move between the loading section, the first station section, and the unloading section and to perform gripping operations. By introducing the material platform structure and the gripping structure, and coordinating them uniformly with the controller, a fully automated process is achieved, from external loading to internal cleaning and then to external unloading of the product.

[0009] In some embodiments, along the arrangement direction from the loading section to the unloading section, the loading section has adjacent first and second placement areas, the first placement area for detachably placing at least one first loading box, and the second placement area for detachably placing at least one second loading box; and / or, along the arrangement direction from the loading section to the unloading section, the unloading section has adjacent third and fourth placement areas, the third placement area for detachably placing at least one first unloading box, and the fourth placement area for detachably placing at least one second unloading box. This allows the laser cleaning apparatus to simultaneously process different types or batches of products, or to replace the loading or unloading boxes without interrupting the cleaning process, improving the continuous operation capability and production efficiency of the equipment.

[0010] In some embodiments, the unloading section has a waste placement area for removably placing a waste box. The controller controls the gripping structure to grab non-conforming products returned to the first work station and place them into the waste box. This embodiment ensures that only qualified products enter the subsequent process, effectively solving the problem of non-conforming products accumulating on the production line or being mixed with qualified products. It avoids manual intervention in sorting and removing non-conforming products, significantly improving the automation level and operating efficiency of the production line.

[0011] In some embodiments, the gripping structure includes a first support, a first drive unit, and a suction cup unit. The first support has a first horizontal rail extending along the arrangement direction from the loading section to the unloading section. The first drive unit is disposed on the first horizontal rail, and a controller is electrically connected to the first drive unit. The first drive unit is movable along the first horizontal rail. The suction cup unit is connected to the first drive unit and is used to adsorb or release the first or second side of the product. This structured gripping structure not only improves the automation level and efficiency of product transfer between various workstations but also ensures that the product can be accurately gripped and placed, thereby significantly improving the operational reliability and production efficiency of the entire laser cleaning device.

[0012] In some embodiments, the inspection mechanism includes a second support, a second drive unit, and an inspection unit. The second support has a second horizontal rail, the extension direction of which is parallel to the extension direction of the first horizontal rail. The second drive unit is disposed on the second horizontal rail, and the inspection unit is disposed on the second drive unit. A controller is electrically connected to the second drive unit and the inspection unit. The second drive unit is movable along the second horizontal rail. The inspection mechanism has the ability to move precisely and linearly along the second horizontal rail, which allows the inspection unit to flexibly adjust its inspection position and scanning path according to the size, shape, or specific inspection requirements of the product, thereby performing comprehensive and detailed scanning and inspection of the product located in the second work station section.

[0013] In some embodiments, the detection unit is a CCD camera, which enables the detection mechanism 40 to acquire high-resolution, high-precision product surface image information. This greatly improves the ability to identify problems such as product surface defects, stains, foreign objects, size deviations, or abnormal shapes, and solves the problems of insufficient detection accuracy and incomplete information acquisition that may exist in traditional detection methods.

[0014] In some embodiments, the laser cleaning mechanism includes a third support, a third drive unit, and a laser cleaning unit. The third support has a third horizontal rail, the extension direction of which is parallel to the extension direction of the second horizontal rail. The third drive unit is disposed on the third horizontal rail, and the laser cleaning unit is disposed on the third drive unit. A controller is electrically connected to the third drive unit and the laser cleaning unit, and the third drive unit can move along the third horizontal rail. This not only improves the efficiency and accuracy of laser cleaning but also optimizes the automation level of the entire cleaning process through collaborative work with the inspection mechanism, reducing manual intervention and thus significantly improving the cleaning quality and production efficiency of the products.

[0015] In some embodiments, the laser cleaning apparatus further includes a worktable, on which at least a portion of the material platform structure, at least a portion of the second support, at least a portion of the third support, and a controller are mounted. By uniformly mounting core functional modules such as at least a portion of the material platform structure, at least a portion of the second support of the detection mechanism, at least a portion of the third support of the laser cleaning mechanism, and the controller onto the worktable, the structural integrity and operational stability of the entire apparatus are significantly improved.

[0016] According to a second aspect of the embodiments of this application, a battery production line is provided. The battery production line includes the laser cleaning apparatus as described above.

[0017] According to a third aspect of the embodiments of this application, a battery electrode cleaning method is provided, which is applied to the aforementioned laser cleaning apparatus, and the battery electrode cleaning method includes the following steps:

[0018] The battery electrode is placed on the carrier plate of the laser cleaning device, wherein the surface of the battery electrode to be cleaned on at least one carrier plate is the first surface, and the surface of the battery electrode to be cleaned on the other carrier plates is the second surface.

[0019] Detect the first face to determine the first position information of the first face, and detect the second face to determine the second position information of the second face;

[0020] The laser cleaning mechanism of the laser cleaning device is preset with first cleaning parameters for the first surface and second cleaning parameters for the second surface. The controller of the laser cleaning device controls the laser cleaning mechanism to perform cleaning operation on the first surface according to the first position information and by calling the first cleaning parameters. The controller controls the laser cleaning mechanism to perform cleaning operation on the second surface according to the second position information and by calling the second cleaning parameters.

[0021] This battery electrode cleaning method can separate battery electrodes with different surfaces to be cleaned and perform targeted testing and cleaning, effectively avoiding the problem that traditional single-station equipment cannot cover the cleaning depth of different surfaces, and significantly improving the stability of battery electrode cleaning depth.

[0022] In some embodiments, within the laser cleaning apparatus, the controller controls the detection mechanism to alternately detect the first position information of the first surface and the second position information of the second surface, and the controller also controls the laser cleaning mechanism to alternately clean the first surface and the second surface. This forms a stable and efficient automated cleaning process, which helps to improve production efficiency.

[0023] In some embodiments, when performing the steps of "detecting the first surface to determine the first position information of the first surface and detecting the second surface to determine the second position information of the second surface", the detection mechanism simultaneously detects and determines whether the battery electrode is qualified; when the battery electrode is determined to be qualified, the controller controls the laser cleaning mechanism to continue to perform the corresponding cleaning operation; when the battery electrode is determined to be unqualified, the controller controls the carrier plate to return and places the unqualified battery electrode into the waste box, thereby realizing the automatic sorting of unqualified products.

[0024] In some embodiments, after the corresponding cleaning operation is completed on the first or second surface, the controller controls the detection mechanism to detect the first or second surface again to determine whether the first or second surface has been cleaned successfully. When the first or second surface is determined to be cleaned successfully, the controller controls the gripping structure of the laser cleaning device to grip the qualified battery electrode and place it into the corresponding unloading box, thereby realizing automated gripping and sorting and improving production efficiency. When the first or second surface is determined to be cleaned unsuccessfully, the controller controls the gripping structure of the laser cleaning device to grip the unsuccessful battery electrode and place it into the waste box, thereby further realizing the automatic sorting of unqualified products.

[0043] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0044] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0045] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0046] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0047] Currently, judging from market trends, the application of battery devices is becoming increasingly widespread. Battery devices are not only used in energy storage power systems such as hydropower, thermal power, wind power, and solar power plants (battery devices used in these applications are generally referred to as energy storage batteries), but also widely used in electric vehicles such as electric bicycles, electric motorcycles, and electric cars (battery devices used in these applications are generally referred to as power batteries). With the continuous expansion of the application areas of battery devices, the market demand is also constantly increasing.

[0048] In related technologies, traditional laser cleaning of battery electrodes involves simultaneously cleaning both the first and second sides of the product at the same workstation. Furthermore, traditional laser cleaning uses a single set of cleaning parameters for both sides. However, due to variations in the uniformity of the material coating and differences in dust removal effectiveness, the cleaning parameters for the four edges of the battery electrode must be set differently for each side. This means that the cleaning parameters for the first side cannot be directly applied to the second side. Consequently, it is difficult to simultaneously meet the depth requirements for both sides at the same cleaning workstation, resulting in poor stability of the battery electrode cleaning depth; the first side may meet the standard, while the second side may fail to do so. For example, when the cleaning depth of the first side meets the standard, the cleaning depth of the second side often fails to meet the standard, and vice versa. This directly leads to a decrease in the product qualification rate.

[0049] Based on the above considerations, embodiments of this application provide a laser cleaning apparatus, and a battery electrode cleaning method is specifically designed for this laser cleaning apparatus. Furthermore, the laser cleaning apparatus is applied to a battery production line to achieve automated battery production. Specifically, this laser cleaning apparatus utilizes a multi-station movable platform structure and multiple carrier plates to distinguish between products with first and second surfaces to be cleaned, enabling the orderly transfer, inspection, and cleaning of products at different stations. This allows for differentiated processing of different surfaces, effectively avoiding the problem of poor depth stability caused by cleaning both surfaces simultaneously at the same station in traditional methods, while simultaneously improving the automation level and production efficiency of the cleaning process.

[0050] To illustrate the technical solutions provided by the embodiments of this application, the following detailed description is provided in conjunction with specific drawings and embodiments.

[0051] According to a first aspect of the embodiments of this application, embodiments of this application provide a laser cleaning apparatus. For example... Figures 1 to 5As shown, the laser cleaning device includes a movable platform structure 10, a detection mechanism 40, a laser cleaning mechanism 50, and a controller 60. The movable platform structure 10 includes a slide rail assembly 11 and a platform module 12 disposed on the slide rail assembly 11. The platform module 12 can reciprocate along the extension direction of the slide rail assembly 11. The slide rail assembly 11 has a first station section 111, a second station section 112, and a third station section 113 connected sequentially along its extension direction. The product to be cleaned is placed on the platform module 12 when the platform module 12 is located at the first station section 111. The slide rail assembly 11 includes multiple slide rails 114 arranged side by side. The platform module 12 includes multiple carrier plates 114. 20. The plurality of carrier plates 120 are respectively disposed on the plurality of slide rails 114. The product to be cleaned surface placed on at least one of the carrier plates 120 is the first surface 91, and the product to be cleaned surface placed on the other carrier plates 120 is the second surface 92. The detection mechanism 40 is disposed corresponding to the second work station section 112. The detection mechanism 40 is used to detect the products transferred to the second work station section 112. The laser cleaning mechanism 50 is disposed corresponding to the third work station section 113. The laser cleaning mechanism 50 performs laser cleaning on the products transferred to the third work station section 113. The platform module 12, the detection mechanism 40 and the laser cleaning mechanism 50 are respectively electrically connected to the controller 60.

[0052] For ease of understanding, the following explains some key terms in this embodiment:

[0053] The mobile platform structure 10 is configured to carry products to be cleaned and move between different workstations. The mobile platform structure 10 typically includes a slide rail assembly 11 for guiding the movement and a platform module 12 for actually carrying the products.

[0054] The slide rail assembly 11 is configured to provide a moving path for the platform module 12. Along its extension direction, the slide rail assembly 11 is sequentially connected to a first work station section 111, a second work station section 112, and a third work station section 113, which are the specific locations of the aforementioned different work stations. These work station sections correspond to different stages of product processing. The first work station section 111 is configured as the product loading area, where the product to be cleaned is placed on the platform module 12. The second work station section 112 is configured as the product inspection area, where the inspection mechanism 40 inspects the product. The third work station section 113 is configured as the product cleaning area, where the laser cleaning mechanism 50 performs laser cleaning on the product.

[0055] The platform module 12 is configured to place products to be cleaned. The platform module 12 can reciprocate along the extension direction of the slide rail assembly 11. The platform module 12 is typically composed of multiple carrier plates 120. The multiple slide rails 114 of the slide rail assembly 11 are arranged side by side, and the multiple carrier plates 120 are correspondingly arranged on these slide rails 114 to support the simultaneous movement of the multiple carrier plates 120. The multiple carrier plates 120 are used to carry different products or different surfaces of the same product to be cleaned.

[0056] The first side 91 and the second side 92 of the product to be cleaned refer to the different surfaces of the product. For example, for a battery electrode 90, these could be the two opposite sides of the battery electrode 90, which require different cleaning parameters or treatment methods. The following explanation uses the battery electrode 90 as an example of the product to be cleaned. Figure 7 As shown. In the laser cleaning apparatus of this application, among the multiple carrier plates 120, one or more carrier plates 120 can be fixed with the first side 91 of the product facing upwards, while the other remaining carrier plates 120 can be fixed with the second side 92 of the product facing upwards; or, the detection mechanism 40 can detect the surface of the product placed on the multiple carrier plates 120 to determine which are the first side 91 and which are the second side 92.

[0057] The inspection unit 40 is configured to perform quality inspection, status inspection and / or physical mark inspection on the product in the second station section 112. For example, it can detect whether there are defects on the product surface or whether it needs to be cleaned, and / or detect the placement status of the product surface to generate physical coordinate parameters, and / or detect physical marks on the product surface (e.g., a triangle symbol indicates that the surface is the first surface 91, and a square symbol indicates that the surface is the second surface 92). In this way, the inspection unit 40 can send instructions to the laser cleaning unit 50 through the controller 60 to indicate whether the surface is the first surface 91 or the second surface 92.

[0058] The laser cleaning unit 50 is configured to perform non-contact cleaning of the product at the third station 113, removing contaminants or coatings from the product surface using laser energy. Furthermore, in some embodiments, the laser cleaning unit 50 can receive instructions from the controller 60 to determine whether the product surface to be cleaned is the first surface 91 or the second surface 92, and then the laser cleaning unit 50 will invoke the corresponding cleaning parameters to perform the cleaning operation on the corresponding surface.

[0059] The controller 60 is configured as the central control unit of the entire laser cleaning device, responsible for coordinating and managing the various operations of the mobile platform module 12, the detection mechanism 40 and the laser cleaning mechanism 50, to ensure the automation and accuracy of the entire cleaning process.

[0060] The movable platform structure 10 of the laser cleaning device may include a slide rail assembly 11 composed of a single linear guide rail. The reciprocating movement of the platform module 12 along the extension direction of the slide rail assembly 11 can be achieved by manual pushing and pulling, or by a motor-driven belt, chain, or lead screw and nut moving pair. The slide rail assembly 11 is sequentially connected to a first work station section 111, a second work station section 112, and a third work station section 113 along its extension direction. These work station sections may simply be pre-defined areas on the slide rail assembly 11, distinguished by physical markings. The product to be cleaned is placed on the platform module 12 when the platform module 12 is located at the first work station section 111. As one possible embodiment, the slide rail assembly 11 may include two slide rails 114 arranged side by side, and the platform module 12 includes two independent carrier plates 120, each carrier plate 120 being disposed on one of the slide rails 114. The surface of the product to be cleaned placed on one of the carrier plates 120 may be designated as the first surface 91, and the surface of the product to be cleaned placed on the other carrier plate 120 may be designated as the second surface 92, for example, by the operator manually distinguishing and placing the products according to their types.

[0061] The detection mechanism 40 of the laser cleaning device can be a visual inspection station fixed above the second work station section 112, where the operator visually inspects the product surface for obvious stains. Alternatively, the detection mechanism 40 of the laser cleaning device can be a simple optical sensor used to detect the presence or approximate location of the product.

[0062] The laser cleaning mechanism 50 of the laser cleaning device can be a laser head fixed above the third station section 113, whose cleaning range covers the entire product. Alternatively, the laser cleaning mechanism 50 can be a manually operated laser cleaning gun, which is used by the operator to clean the product in the third station section 113 and perform uniform cleaning using preset single cleaning parameters.

[0063] The laser cleaning apparatus of this application, by setting up a movable platform structure 10 with multiple workstations and using multiple carrier plates 120 to separately carry products with first surface 91 and second surface 92 to be cleaned, realizes the orderly transfer, inspection and cleaning of products in different workstations. Therefore, it can perform differentiated treatment for different surfaces to be cleaned, effectively avoiding the problem of poor depth stability caused by cleaning two surfaces at the same workstation in traditional methods. At the same time, it improves the automation level and production efficiency of the cleaning process and reduces the risk of manual intervention and disruption of rules.

[0064] To further optimize the laser cleaning device's ability to process products with different surfaces to be cleaned, in some embodiments, such as... Figure 3As shown, the multiple slide rails 114 include a first rail 1141 and a second rail 1142, and the multiple carrier plates 120 include a first carrier plate 121 and a second carrier plate 122. The first carrier plate 121 is disposed on the first rail 1141, and the second carrier plate 122 is disposed on the second rail 1142. The surface of the product to be cleaned placed on the first carrier plate 121 is the first surface 91, and the surface of the product to be cleaned placed on the second carrier plate 122 is the second surface 92. Specifically, the multiple slide rails 114 are explicitly defined as including the first rail 1141 and the second rail 1142. The first rail 1141 and the second rail 1142 are two independent rails arranged side by side. Each of them carries a carrier plate 120 and guides the carrier plate 120 to move between various stations of the laser cleaning device. The side-by-side arrangement of the first rail 1141 and the second rail 1142 allows the two carrier plates 120 to run in parallel or alternately in space, thereby providing a physical basis for simultaneously processing products of different types or with different cleaning requirements. Multiple carrier plates 120 are explicitly defined as including a first carrier plate 121 and a second carrier plate 122. The first carrier plate 121 and the second carrier plate 122 are platforms for carrying products to be cleaned. They correspond to the first rail 1141 and the second rail 1142, respectively. Each carrier plate 120 typically has a structure for fixing the product, such as a clamp, suction cup, or positioning groove, to ensure that the product remains stable during movement and cleaning. In this embodiment, the first carrier plate 121 and the second carrier plate 122 can move independently from the first work station section 111 to the second work station section 112, and then to the third work station section 113 on their respective rails, or they can reciprocate between work stations. The surface of the product to be cleaned placed on the first carrier plate 121 is designated as the first surface 91, and the surface of the product to be cleaned placed on the second carrier plate 122 is designated as the second surface 92. The first surface 91 and the second surface 92 can refer to different physical surfaces of the product, such as the front and back, top and bottom, or surfaces with different material properties or degrees of contamination, or different surfaces of different products. This distinction allows the laser cleaning device to assign the product to different carrier plates 120 for processing according to the specific cleaning requirements of the product. For example, a product that needs to be cleaned on the front can be placed on the first carrier plate 121, while a product that needs to be cleaned on the back can be placed on the second carrier plate 122.

[0065] Through the above technical solution, the laser cleaning device, by clearly defining the first track 1141 and the second track 1142, as well as the corresponding first carrier plate 121 and the second carrier plate 122, achieves the ability to process products with different surfaces to be cleaned in parallel. This allows the device to simultaneously carry and move two types of products with different cleaning requirements; for example, one type of product needs cleaning its first surface 91, while another type needs cleaning its second surface 92. During the entire cleaning process, these two types of products can be independently inspected by the detection mechanism 40 on their respective carrier plates 120 and then cleaned by the laser cleaning mechanism 50, thus avoiding the additional surface-changing operations or waiting time required by traditional single-track or single-carrier-plate 120 systems when processing products with different cleaning surfaces. This parallel processing mechanism significantly improves the overall working efficiency and throughput of the laser cleaning device, and is particularly suitable for applications requiring cleaning of multiple surfaces of products or simultaneous processing of multiple product types, thereby optimizing the production process and reducing the cleaning cost per unit product.

[0066] In some embodiments of this application, such as Figure 1 , Figure 4 and Figure 5 As shown, the laser cleaning device also includes a material platform structure 20 and a gripping structure 30. The material platform structure 20 has a spaced loading section 21 and a unloading section 22. The loading section 21 is used to detachably place the loading box 71, and the unloading section 22 is used to detachably place the unloading box 72. A first station section 111 is located between the loading section 21 and the unloading section 22. A controller 60 is electrically connected to the gripping structure 30, and the controller 60 controls the gripping structure 30 to move between the loading section 21, the first station section 111, and the unloading section 22 and to perform gripping operations. The material platform structure 20 is an area for storing products to be cleaned and cleaned products. Its main function is to achieve batch, orderly storage and turnover of products. The material platform structure 20 can be one or more physical platforms, for example, it can be designed as a rack with multiple slots, or a storage unit that can accommodate multiple boxes. The material platform structure 20 is designed to provide a stable interface for automated loading and unloading. The gripping structure 30 is an actuator used to precisely transfer products between different positions. The gripping structure 30 typically includes one or more robotic arms or grippers capable of adsorbing, clamping, or releasing products according to control commands. For example, it can take various forms such as vacuum suction cups, mechanical grippers, or electromagnetic adsorbents to accommodate products of different shapes, sizes, and materials. The design of the gripping structure 30 should ensure no damage to the product during gripping and placement, and possess high-precision positioning capabilities.

[0067] The loading section 21 is a dedicated area within the platform structure 20 for placing products to be cleaned. This area is typically designed to accommodate one or more loading boxes 71 pre-loaded with products to be cleaned. The loading section 21 can be a simple placement platform or a hopper with automatic feeding functionality; for example, it can employ a stacked box design, where the next box automatically moves into the receiving position after a product is removed from one box. The unloading section 22 is a dedicated area within the platform structure 20 for collecting cleaned products. This area is typically designed to accommodate one or more unloading boxes 72 for receiving cleaned products removed from the mobile platform structure 10. The unloading section 22 can also be a simple placement platform or a hopper with automatic collection functionality; for example, it can employ a stacked box design similar to the loading section 21, or it can be an area for sorting and collecting qualified and unqualified products. The loading box 71 is a container for holding products to be cleaned in batches. The loading box 71 should facilitate the orderly arrangement of products and the identification and operation of the gripping structure 30. The loading box 71 can adopt standardized dimensions and interfaces to facilitate quick changeover and turnover on the production line. The unloading box 72 is a container for holding cleaned products in batches. The unloading box 72 should facilitate the orderly collection and subsequent processing of products. The unloading box 72 can also adopt standardized dimensions and interfaces to improve production efficiency.

[0068] The first workstation section 111 is located between the loading section 21 and the unloading section 22. This layout makes the first workstation section 111 the central hub for products entering and exiting the device from the outside. The gripping structure 30 can take the product to be cleaned from the loading section 21 and place it on the platform module 12 located in the first workstation section 111; at the same time, it can also take the cleaned product from the platform module 12 and place it on the unloading section 22. This centralized design simplifies the movement path of the gripping structure 30 and improves work efficiency. The controller 60, as the control core of the entire device, receives the status information of the gripping structure 30 through electrical connection and sends motion commands and operation commands to it. Furthermore, the controller 60, according to a preset program or real-time feedback, precisely coordinates the movement of the gripping structure 30 between the loading section 21, the first workstation section 111, and the unloading section 22, and performs gripping operations such as adsorption and release, thereby realizing automated loading, unloading, and transfer of products.

[0069] By introducing the material platform structure 20 and the gripping structure 30, and coordinating them with the controller 60, the laser cleaning device in this embodiment achieves a fully automated process from external loading to internal cleaning and then to external unloading. Specifically, the gripping structure 30 can automatically grip the product to be cleaned from the loading box 71 in the loading section 21 and accurately place it on the carrier module 12 located in the first station section 111, thus eliminating the manual loading step. After the product has been cleaned, the gripping structure 30 can also grip the cleaned product on the carrier module 12 and place it into the unloading box 72 in the unloading section 22, realizing automated unloading. This automated loading and unloading mechanism significantly improves production efficiency, reduces labor costs and operational error rates, and ensures the continuity and consistency of the product during the cleaning process, thereby making the entire laser cleaning process more efficient, stable, and reliable. Furthermore, the layout of the first station section 111 between the loading section 21 and the unloading section 22 optimizes the movement path of the gripping structure 30, further improving the efficiency of automated operation.

[0070] In some embodiments of this application, such as Figure 4 and Figure 5As shown, along the arrangement direction from the loading section 21 to the unloading section 22, the loading section 21 has adjacent first placement area 211 and second placement area 212. The first placement area 211 is used to detachably place at least one first loading box 711, and the second placement area 212 is used to detachably place at least one second loading box 712; and / or, along the arrangement direction from the loading section 21 to the unloading section 22, the unloading section 22 has adjacent third placement area 221 and fourth placement area 222. The third placement area 221 is used to detachably place at least one first unloading box 721, and the fourth placement area 222 is used to detachably place at least one second unloading box 722. Specifically, the loading section 21 has adjacent first placement area 211 and second placement area 212. The first placement area 211 and the second placement area 212 are two independent and adjacent physical spaces divided within the loading section 21, used to hold different loading boxes 71 respectively. These areas can be clearly defined by physical partitions, positioning slots, visual recognition marks, or sensor arrays to ensure that the gripping structure 30 can accurately identify and operate them. For example, when two different specifications or batches of products need to be processed, the first product can be placed in the first loading box 711 and placed in the first placement area 211, and the second product can be placed in the second loading box 712 and placed in the second placement area 212. The first placement area 211 is used to detachably hold at least one first loading box 711, and the second placement area 212 is used to detachably hold at least one second loading box 712. The first loading box 711 and the second loading box 712 are containers for holding products to be cleaned, and they should facilitate product access and the adsorption of the gripping structure 30. These loading boxes 71 can be standardized trays, pallets, or racks. Their detachability allows operators to quickly replace empty boxes or replenish products without interrupting the entire cleaning process. Meanwhile, the unloading section 22 has adjacent third and fourth placement areas 221 and 222. Similar to the loading section 21, these three areas are two independent and adjacent physical spaces within the unloading section 22, each designed to hold different unloading boxes 72. These areas can also be defined by physical partitions, positioning slots, or sensors to achieve the classified collection of cleaned products. For example, qualified products can be placed in the first unloading box 721 and then in the third placement area 221, while products requiring re-inspection can be placed in the second unloading box 722 and then in the fourth placement area 222. The third placement area 221 is used to detachably place at least one first discharge box 721, and the fourth placement area 222 is used to detachably place at least one second discharge box 722. The first discharge box 721 and the second discharge box 722 are containers for collecting the cleaned products, and should facilitate product reception and subsequent transfer. These discharge boxes 72 are also detachable to allow operators to quickly replace them when they are full, thereby ensuring the continuity of the cleaning process.The arrangement direction along the loading section 21 to the unloading section 22 refers to the spatial layout of these placement areas on the material platform structure 20, which is usually consistent with the overall flow direction of the product from loading to unloading. This layout helps optimize the working path of the gripping structure 30, reduce unnecessary movement distances and time, thereby improving overall operational efficiency.

[0071] Through the above technical solution, multiple adjacent placement areas are set in the loading section 21 and / or unloading section 22, respectively for detachably placing multiple loading boxes 71 and / or unloading boxes 72. This allows the laser cleaning device to process different types or batches of products simultaneously, or to replace the loading box 71 or unloading box 72 without interrupting the cleaning process. When a loading box 71 is full, the gripping structure 30 can immediately switch to another loading box 71 to pick up materials, thus avoiding downtime caused by waiting to replace the box. Similarly, when the unloading box 72 is full, the gripping structure 30 can place the product into another empty unloading box 72, improving the continuous operation capability and production efficiency of the equipment. This design significantly enhances the flexibility of the equipment, enabling it to adapt to the production needs of multiple varieties and small batches, and effectively reduces the frequency and labor intensity of manual intervention.

[0072] In some embodiments of this application, the unloading section 22 of the laser cleaning apparatus has a waste placement area 223, which is used to detachably place the waste box 73. The controller 60 controls the gripping structure 30 to grip the non-conforming products returned to the first work station 111 and place them into the waste box 73. Specifically, the waste placement area 223 is a space specifically designated within the unloading section 22 for storing discarded or non-conforming products. Its purpose is to physically isolate non-conforming products from conforming products, avoid confusion, and facilitate subsequent waste disposal. The waste box 73 is a movable container for collecting non-conforming products. Its detachable placement means that the waste box 73 can be easily removed from the waste placement area 223, emptied, and repositioned, thereby achieving batch processing of waste and reducing downtime. The controller 60, as the control core of the entire apparatus, is responsible for receiving the detection results from the detection mechanism 40 and determining whether the product is conforming according to preset logic. When a product is deemed non-conforming, the controller 60 issues a command. The gripping structure 30, which is the actuator for handling the product (e.g., a robotic arm with a suction cup), moves to the location of the non-conforming product after receiving the command from the controller 60. A non-conforming product is one that fails to meet quality standards after inspection by the inspection mechanism 40, such as a product with inherent defects or one that has not been properly cleaned. "Return to the first station segment 111" means that after the first inspection before cleaning or the second inspection after cleaning, the non-conforming product is guided back to the first station segment 111 by the system so that the gripping structure 30 can process it. The gripping structure 30 uses suction or other methods to pick up the non-conforming product from the first station segment 111 and precisely places it into the waste box 73 within the waste placement area 223.

[0073] By setting up a waste placement area 223 in the unloading section 22 and configuring a detachable waste box 73, and with the controller 60 controlling the gripping structure 30 to automatically grab the non-conforming products returned to the first workstation section 111 into the waste box 73, this embodiment effectively solves the problem of non-conforming products accumulating on the production line or being mixed with qualified products. It avoids manual intervention in sorting and removing non-conforming products, significantly improving the automation level and operating efficiency of the production line. Simultaneously, the detachable design of the waste box 73 makes waste collection and processing more convenient, reducing downtime caused by waste disposal and ensuring the continuity and cleanliness of the production process. This embodiment ensures that only qualified products enter subsequent processes, thereby improving the quality control capability of the final product.

[0074] In some embodiments of this application, such as Figure 1As shown, the gripping structure 30 includes a first support 31, a first drive unit 32, and a suction cup unit 33. The first support 31 has a first horizontal rail 311, which extends along the arrangement direction from the loading unit 21 to the unloading unit 22. The first drive unit 32 is disposed on the first horizontal rail 311. The controller 60 is electrically connected to the first drive unit 32. The first drive unit 32 can move along the first horizontal rail 311. The suction cup unit 33 is connected to the first drive unit 32 and is used to adsorb or release the first surface 91 or the second surface 92 of the product.

[0075] The gripping structure 30 is the core component used for product transfer and positioning within the device. It aims to ensure that products can be accurately and stably picked up and placed between different workstations, especially when handling non-conforming products, requiring high flexibility and reliability. The first support 31 is the basic support component of the gripping structure 30, typically made of high-strength materials such as aluminum alloy or steel. The main function of the first support 31 is to provide a stable mounting platform for other components of the gripping structure 30 and to bear the loads generated during product gripping and movement. The rigidity and stability of the first support 31 directly affect the overall motion accuracy and repeatability of the gripping structure 30. The first cross rail 311 is a linear guide mechanism mounted on the first support 31, used to define the movement path of the gripping structure 30 in a specific direction. This cross rail is typically in the form of a linear guide, V-shaped guide, or roller guide, and its surface is precision-machined to ensure smooth, low-friction sliding of the moving parts. The first horizontal rail 311 extends along the arrangement direction from the loading section 21 to the unloading section 22, enabling the gripping structure 30 to cover the entire product processing area and realize product operations in various stages such as loading, cleaning, inspection, and unloading. The first drive unit 32 is the power unit that drives the gripping structure 30 to move along the first horizontal rail 311. The first drive unit 32 is usually composed of a servo motor or stepper motor and a transmission mechanism (such as a synchronous belt, ball screw, or rack and pinion). The controller 60 precisely controls the first drive unit 32 through electrical connection, enabling it to achieve high-speed, high-precision position control and speed adjustment, thereby ensuring that the gripping structure 30 can accurately reach the target position and perform operations. The suction cup part 33 is the execution part that directly contacts the product with the gripping structure 30, used to pick up and release the product by suction. The suction cup part 33 is usually composed of one or more vacuum suction cups, which are made of elastic materials (such as silicone or rubber) and generate negative pressure through a vacuum generator. The suction cup 33 can reliably adsorb the product according to its surface characteristics (first surface 91 or second surface 92), avoiding damage to the product and ensuring the stability of the product during the transfer process.

[0076] Through the above technical solution, the gripping structure 30 is specifically designed to include a first support 31, a first horizontal rail 311, a first drive unit 32, and a suction cup unit 33. The first support 31 and the first horizontal rail 311 provide a stable and precise linear movement path for the gripping structure 30. Under the precise control of the controller 60, the first drive unit 32 ensures that the gripping structure 30 can be efficiently and accurately positioned and moved throughout the entire working area (including the loading section 21, the first workstation section 111, the unloading section 22, and the waste placement area 223). The suction cup unit 33 can reliably adsorb and release the product according to the different surfaces to be cleaned (first surface 91 or second surface 92), effectively solving the problem of unstable gripping or damage that may occur during product transfer. This structured gripping structure 30 not only improves the automation level and efficiency of product transfer between various workstations but also ensures that the product can be accurately gripped and placed, thereby significantly improving the operational reliability and production efficiency of the entire laser cleaning device.

[0077] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the detection mechanism 40 includes a second support 41, a second drive unit 42, and a detection unit 43. The second support 41 serves as the structural support for the detection mechanism 40, providing a stable mounting base for subsequent moving parts. The second support 41 has a second horizontal rail 411, the extension direction of which is parallel to the extension direction of the first horizontal rail 311 of the gripping structure 30. This parallel arrangement helps to coordinate the spatial layout of the detection mechanism 40 and the gripping mechanism, providing the possibility for subsequent collaborative operation. The second drive unit 42 is mounted on the second horizontal rail 411. The function of the second drive unit 42 is to drive the detection unit 43 to move precisely linearly along the second horizontal rail 411. The second drive unit 42 is typically driven by a motor (e.g., a stepper motor or a servo motor), and through a transmission mechanism such as a ball screw, synchronous belt, or rack and pinion, it realizes the reciprocating motion or positioning of the detection unit 43 on a predetermined path. The detection unit 43 is mounted on the second drive unit 42 and is the core component for performing the actual detection task. The detection unit 43 can be various types of sensors or imaging devices, such as optical sensors, vision sensors, or other detection units used to acquire product surface feature information. The controller 60 is electrically connected to the second drive unit 42 and the detection unit 43. The controller 60 can send motion commands to the second drive unit 42 to precisely control the position and speed of the detection unit 43 on the second horizontal rail, and simultaneously receive the data collected by the detection unit 43, process and analyze it. In this embodiment, the detection unit 43 can move along the second horizontal rail 411, thereby covering the entire product area on the second workstation section 112, achieving comprehensive product detection.

[0078] Through the above technical solution, the inspection mechanism 40 is no longer fixed or simply movable, but has the ability to move precisely and linearly along the second horizontal rail. This allows the inspection unit 43 to flexibly adjust its inspection position and scanning path according to the size, shape, or specific inspection requirements of the product, thereby performing comprehensive and detailed scanning and inspection of the product located in the second workstation section 112. The controller 60's coordinated control of the second drive unit 42 and the inspection unit 43 ensures the automation, high precision, and high efficiency of the inspection process. This movable inspection mechanism 40 significantly improves the adaptability and flexibility of the laser cleaning device in the product inspection process, effectively handling diverse product inspection tasks, improving inspection coverage and accuracy, thereby ensuring the quality of subsequent laser cleaning and optimizing the efficiency of the overall production process.

[0079] In some embodiments of this application, the detection unit 43 is a CCD camera. Specifically, a CCD camera (Charge-Coupled Device Camera) is a digital camera that uses a charge-coupled device as a photosensitive element. It can convert light signals into charge signals, and then convert the charge signals into digital image data, thereby capturing images of objects. As the detection unit 43, the CCD camera can acquire detailed image information of the product to be cleaned, including its surface features, defects, location, and orientation. A typical implementation of a CCD camera includes a CCD sensor, an optical lens, an image processing unit, and a data transmission interface. When the product is transferred to the second station section 112, the CCD camera captures light from the product surface through the optical lens. The CCD sensor converts the light signals into charge packets, which are transmitted step by step under the drive of clock pulses and finally converted into voltage signals. After analog-to-digital conversion, a digital image is formed. This image data is then transmitted to the controller 60, which analyzes the image using a preset image processing algorithm to determine whether the product is qualified or to calculate the precise coordinates and path required for laser cleaning.

[0080] Through the above technical solution, the detection unit 43 is specifically configured as a CCD camera, enabling the detection mechanism 40 to acquire high-resolution, high-precision product surface image information. This greatly improves the ability to identify problems such as product surface defects, stains, foreign objects, dimensional deviations, or abnormal shapes, solving the problems of insufficient detection accuracy and incomplete information acquisition that may exist in traditional detection methods. The detection mechanism 40 includes a second support 41, a second drive unit 42, and a detection unit 43. The second support 41 has a second horizontal rail, the extension direction of which is parallel to the extension direction of the first horizontal rail 311. The second drive unit 42 is mounted on the second horizontal rail, and the detection unit 43 is mounted on the second drive unit 42. The controller 60 is electrically connected to the second drive unit 42 and the detection unit 43. The second drive unit 42 is configured to move along the second horizontal rail, allowing the CCD camera to move along the second horizontal rail with the second drive unit 42, achieving a comprehensive scan and detection of the entire product surface to be cleaned, ensuring no omissions. Based on detailed image data provided by the CCD camera, the controller 60 can more accurately determine product quality and provide precise positioning and cleaning parameters for the subsequent laser cleaning mechanism 50, thereby significantly improving the efficiency and quality of laser cleaning, reducing the inflow of unqualified products, and reducing reliance on manual inspection.

[0081] In some embodiments of this application, such as Figure 1As shown, the laser cleaning mechanism 50 includes a third support 51, a third drive unit 52, and a laser cleaning unit 53. The third support 51 has a third horizontal rail 511, the extension direction of which is parallel to the extension direction of the second horizontal rail. The third drive unit 52 is mounted on the third horizontal rail 511, and the laser cleaning unit 53 is mounted on the third drive unit 52. The controller 60 is electrically connected to the third drive unit 52 and the laser cleaning unit 53. The third drive unit 52 can move along the third horizontal rail 511. Specifically, the laser cleaning mechanism 50 is the core functional unit of this device, and its main task is to remove contaminants from the surface of the product using laser energy. The third support 51 serves as the structural foundation of the laser cleaning mechanism 50, providing stable support and a precise positioning platform for the laser cleaning unit 53 and its drive system. This support is typically made of high-rigidity materials (such as precision-machined aluminum alloy or steel) to ensure that the geometric accuracy and stability of the mechanism can be maintained under high-speed movement and laser action, effectively suppressing vibration and thus ensuring the quality of laser cleaning. The third horizontal rail 511 is a linear guide component mounted on the third support 51, used to guide the laser cleaning unit 53 to perform precise linear motion. This rail typically uses a high-precision linear guide, such as a ball linear guide or a crossed roller guide, to provide low-friction, high-load-bearing, and high-positioning-accuracy motion. The extension direction of the third horizontal rail 511 is parallel to the extension direction of the second horizontal rail 411, which helps simplify system integration and motion control, ensuring that the motion axis of the laser cleaning mechanism 50 is consistent with the motion axis of the detection mechanism 40, facilitating coordinated operation between the two. The third drive unit 52 is responsible for driving the laser cleaning unit 53 to reciprocate or position along the third horizontal rail 511. This drive unit typically consists of a servo motor or stepper motor and a precision transmission mechanism (such as a ball screw, synchronous belt, or rack and pinion). The controller 60 sends precise motion commands to the third drive unit 52 to achieve high-speed, high-precision positioning and scanning of the laser cleaning unit 53 within the third workstation section 113, adapting to the coverage requirements of different cleaning areas and the planning of cleaning paths. The laser cleaning unit 53 is the component that directly performs the cleaning operation. Its core components include a laser, a beam transmission system, a scanning galvanometer, and a focusing system. The laser generates a high-energy laser beam, which is guided to the scanning galvanometer via a beam transmission system (such as an optical fiber). The scanning galvanometer then controls the laser beam to perform a two-dimensional scan on the surface of the product to be cleaned with extremely high speed and precision. The focusing system ensures that the laser energy achieves the optimal cleaning effect within the working distance. The laser cleaning unit 53 can adjust laser parameters, such as power, frequency, pulse width, and scanning speed, according to cleaning requirements to achieve effective and non-destructive cleaning of different types of contaminants and substrates. The controller 60, as the central control unit of the entire device, interacts with the third drive unit 52 and the laser cleaning unit 53 via electrical connection for data and command exchange.This allows the controller 60 to monitor the motion status of the third drive unit 52 in real time and precisely control its movement trajectory and speed. Simultaneously, the controller 60 can dynamically adjust the working parameters of the laser cleaning unit 53 based on preset cleaning programs or information feedback from the detection mechanism 40, achieving automated, intelligent, and refined management of the cleaning process. The ability of the third drive unit 52 to move along the third horizontal rail 511 gives the laser cleaning mechanism 50 the ability to flexibly position itself spatially and plan its path within the third workstation section 113. This mobility allows the laser cleaning unit 53 to precisely cover any area of ​​the product surface to be cleaned, whether performing overall scanning cleaning or localized fine cleaning of specific defect areas. Precise control of movement ensures uniform distribution of laser energy and consistency of cleaning results, thereby improving cleaning quality and efficiency.

[0082] By introducing the third support 51, the third horizontal rail 511, the third drive unit 52, and the laser cleaning unit 53, and ensuring that the extension direction of the third horizontal rail 511 is parallel to the second horizontal rail, the laser cleaning mechanism 50 of this embodiment can achieve precise and flexible positioning and movement of the laser cleaning unit 53 within the third workstation section 113. The controlled movement of the third drive unit 52 along the third horizontal rail 511 allows the laser cleaning unit 53 to precisely adjust the cleaning path and range according to the product's size, shape, and defect information provided by the detection mechanism 40, ensuring that laser energy can be applied uniformly and effectively to the surface to be cleaned. This not only improves the efficiency and accuracy of laser cleaning but also optimizes the automation level of the entire cleaning process through collaborative work with the detection mechanism 40, reducing manual intervention and thus significantly improving product cleaning quality and production efficiency.

[0083] In some embodiments of this application, such as Figure 1 and Figure 3 As shown, the laser cleaning apparatus also includes a worktable 80, on which at least a portion of the material platform structure 20, at least a portion of the second support 41, at least a portion of the third support 51, and the controller 60 are mounted. Specifically, the worktable 80 refers to a robust and stable foundation platform or frame, whose main function is to provide unified support and mounting reference for the various core functional modules of the laser cleaning apparatus. The worktable 80 is typically made of high-strength materials (e.g., steel, aluminum alloy, or composite materials) to ensure sufficient rigidity and vibration resistance. The surface of the worktable 80 can be precision machined to provide a flat and level mounting surface, thereby ensuring the relative positional accuracy of the various components mounted on it. To further enhance stability, the bottom of the worktable 80 can be equipped with adjustable leveling feet or shock-absorbing pads to adapt to different installation environments and effectively isolate external vibrations.

[0084] At least a portion of the material platform structure 20, at least a portion of the second bracket 41, at least a portion of the third bracket 51, and the controller 60 are all mounted on the worktable 80, meaning that these key functional modules are centrally and securely fixed on this common platform. The material platform structure 20, responsible for loading and unloading products, is mounted on the worktable 80, ensuring precise alignment and stable operation between itself and the moving platform structure 10 and the gripping structure 30. The second bracket 41, serving as a support component for the detection mechanism 40, is mounted on the worktable 80, ensuring the positional accuracy and stability of the detection unit 43 (e.g., a CCD camera) when detecting products, thereby improving the reliability of the detection results. The third bracket 51, serving as a support component for the laser cleaning mechanism 50, is mounted on the worktable 80, ensuring that the laser cleaning unit 53 maintains a precise path and stable energy output when cleaning products, thereby improving the cleaning effect. The controller 60, serving as the "brain" of the entire device, is mounted on the workbench 80. This not only facilitates centralized management and wiring but also effectively protects the controller 60 from external environmental influences and ensures stable and reliable signal transmission between it and the various actuators. This integrated installation is typically achieved using bolts, screws, or other mechanical fasteners to ensure a secure connection between each component and the workbench 80. During installation, specialized calibration tools may be required to ensure that the relative positions of the modules meet design requirements.

[0085] Through the above technical solution, at least a portion of the material platform structure 20, at least a portion of the second support 41 of the detection mechanism 40, at least a portion of the third support 51 of the laser cleaning mechanism 50, and the controller 60, as core functional modules, are uniformly installed on the worktable 80, significantly improving the structural integrity and operational stability of the entire device. The worktable 80, as a robust common reference, effectively solves problems such as alignment difficulties, vibration transmission, and low space utilization that may result from independent installation of each module. This integrated installation method ensures that the detection mechanism 40 and the laser cleaning mechanism 50 maintain a precise and stable relative position with the product during operation, thereby greatly improving the accuracy of detection and the precision of laser cleaning. Furthermore, centralized installation simplifies the overall design and assembly process of the device, reduces the required external support structures and wiring complexity, resulting in a smaller footprint and easier maintenance, thus improving the overall reliability and production efficiency of the laser cleaning device.

[0086] The following example will provide a more detailed explanation of the above technical solution:

[0087] In a battery electrode 90 production workshop, a batch of battery electrodes 90 need to be laser cleaned. These battery electrodes 90 have a first surface 91 and a second surface 92 to be cleaned. Due to the differences in the material coating characteristics of the first surface 91 and the second surface 92, as well as the required cleaning depth, different cleaning parameters are required. Traditional cleaning equipment often attempts to clean both surfaces of the battery electrode 90 at the same station, resulting in poor cleaning depth stability and difficulty in simultaneously meeting the cleaning requirements of both surfaces.

[0088] The laser cleaning apparatus in this example provides a solution. The laser cleaning apparatus includes a movable platform structure 10, the core of which is a slide rail assembly 11. The slide rail assembly 11 is sequentially connected to a first work station section 111, a second work station section 112, and a third work station section 113 along its extension direction. The slide rail assembly 11 consists of multiple slide rails 114 arranged side-by-side, such as a first rail 1141 and a second rail 1142. Multiple carrier plates 120, such as a first carrier plate 121 and a second carrier plate 122, are correspondingly arranged on these slide rails 114.

[0089] At the start of the cleaning operation, the controller 60 controls the gripping structure 30 to grip the battery electrode 90 to be cleaned from the loading section 21 of the material platform structure 20. The loading section 21 of the material platform structure 20 has a first placement area 211 and a second placement area 212, which are used to place the first loading box 711 and the second loading box 712 containing battery electrode 90 of different types or different cleaning surfaces, respectively. For example, the battery electrode 90 taken from the first loading box 711, with the first surface 91 to be cleaned, is placed on the first carrier plate 121 of the movable carrier structure 10; while the battery electrode 90 taken from the second loading box 712, with the second surface 92 to be cleaned, is placed on the second carrier plate 122. This allows battery electrode 90 with different cleaning surfaces to be processed in parallel on different carrier plates 120, avoiding the problem of cleaning different surfaces at the same station in traditional solutions.

[0090] After the battery electrode 90 is placed on the stage module 12 of the first workstation section 111, the controller 60 drives the stage module 12 to move along the extension direction of the slide rail assembly 11. First, the stage module 12 transfers the battery electrode 90 to the second workstation section 112. In the second workstation section 112, the inspection mechanism 40 inspects the battery electrode 90 transferred there. The inspection mechanism 40 includes a second support 41, a second drive unit 42, and an inspection unit 43, wherein the inspection unit 43 can be a CCD camera. The controller 60 controls the second drive unit 42 to move along the second transverse rail, so that the CCD camera performs visual inspection of the battery electrode 90, such as checking whether there are foreign objects on the surface of the battery electrode 90, whether the size meets the requirements, etc. If a defective product is detected, the controller 60 records its information, and then directly returns to the first workstation section 111 and is picked up by the gripping structure 30 and placed in the waste box 73.

[0091] After the inspection is completed and the product is qualified, the platform module 12 continues to move, transferring the battery electrode 90 to the third station section 113. In the third station section 113, the laser cleaning mechanism 50 performs laser cleaning on the battery electrode 90. The laser cleaning mechanism 50 includes a third support 51, a third drive unit 52, and a laser cleaning unit 53. The controller 60 controls the laser cleaning unit 53 to precisely clean the battery electrode 90 using preset, targeted cleaning parameters based on whether the battery electrode 90 is the first side 91 or the second side 92, and the inspection results. For example, one set of cleaning parameters is used for the first side 91 of the battery electrode 90 on the first carrier plate 121, and another set of cleaning parameters is used for the second side 92 of the battery electrode 90 on the second carrier plate 122, thereby ensuring that the cleaning depth of different sides meets the requirements and solving the problem of poor cleaning depth stability.

[0092] After cleaning, the platform module 12 returns the cleaned battery electrode 90 to the second workstation section 112, where the inspection mechanism 40 inspects the cleaned battery electrode 90 again. After inspection, the platform module 12 returns the cleaned battery electrode 90 to the first workstation section 111. At this time, the controller 60 again controls the gripping structure 30 to intervene. If the battery electrode 90 is a qualified product, the gripping structure 30 will pick it up from the platform module 12 and place it into the first or second unloading box 721 in the third or fourth placement area 222 of the unloading section 22 of the material platform structure 20. If the battery electrode 90 was previously detected as a defective product, the controller 60 will control the gripping structure 30 to pick it up and place it into the waste box 73 in the waste placement area 223 of the unloading section 22, thus achieving automatic sorting of defective products.

[0093] Throughout the process, the controller 60, as the core control unit, electrically connects and coordinates the operation of the moving platform module 12, the detection mechanism 40, the laser cleaning mechanism 50, and the gripping structure 30, ensuring that all mechanisms work together. The material platform structure 20, the second support 41, the third support 51, and the controller 60 are all installed on the workbench 80, forming a stable and efficient automated cleaning system.

[0094] Through its multi-rail 114, multi-carrier plate 120, and multi-station design, this laser cleaning device can separate battery electrode sheets 90 from different surfaces to be cleaned, and perform targeted inspection and cleaning. This effectively avoids the problem of traditional single-station equipment being unable to handle the cleaning depth of different surfaces simultaneously, significantly improving the stability of the cleaning depth of the battery electrode sheets 90. Furthermore, this laser cleaning device improves production efficiency through automated gripping and sorting, avoiding the chaos and inefficiency that can result from manual placement of the battery electrode sheets 90.

[0095] According to a second aspect of the embodiments of this application, a battery production line is provided for the assembly line production of battery devices. The battery production line includes the laser cleaning apparatus as described above.

[0096] According to a third aspect of the embodiments of this application, a battery electrode cleaning method is provided, which is applied to the aforementioned laser cleaning apparatus. Figure 6 As shown, the battery electrode cleaning method includes the following steps:

[0097] Step S10: Place the battery electrode 90 on the carrier plate 120 of the laser cleaning device, wherein the surface to be cleaned of the battery electrode 90 on at least one carrier plate 120 is the first surface 91, and the surface to be cleaned of the battery electrode 90 on the other carrier plates 120 is the second surface 92. As an example, the controller 60 controls the gripping structure 30 to grip the battery electrode 90 to be cleaned from the loading section 21 of the material table structure 20. For example, the battery electrode 90 taken from the first loading box 711, with the first surface 91 to be cleaned, is placed on the first carrier plate 121 of the movable carrier table structure 10; while the battery electrode 90 taken from the second loading box 712, with the second surface 92 to be cleaned, is placed on the second carrier plate 122. This allows battery electrode 90s with different surfaces to be cleaned to be processed in parallel on different carrier plates 120, avoiding the problem of cleaning different surfaces at the same station in the traditional solution.

[0098] Step S20: Detect the first surface 91 to determine the first position information of the first surface 91, and detect the second surface 92 to determine the second position information of the second surface 92. For example, after the battery electrode 90 is placed on the platform module 12 of the first work station section 111, the controller 60 drives the platform module 12 to move along the extension direction of the slide rail assembly 11 to the second work station section 112. In the second work station section 112, the detection mechanism 40 detects the battery electrode 90 transferred there, thereby determining the first position information of the first surface 91 or the second position information of the second surface 92 of the detected battery electrode 90.

[0099] Step S30: The laser cleaning mechanism 50 of the laser cleaning device presets first cleaning parameters for the first surface 91 and second cleaning parameters for the second surface 92. The controller 60 of the laser cleaning device, based on the first position information and by calling the first cleaning parameters, controls the laser cleaning mechanism 50 to perform a cleaning operation on the first surface 91. The controller 60, based on the second position information and by calling the second cleaning parameters, controls the laser cleaning mechanism 50 to perform a cleaning operation on the second surface 92. As an example, after the inspection is completed and the product is qualified, the platform module 12 continues to move, transferring the battery electrode 90 to the third station section 113. In the third station section 113, the laser cleaning mechanism 50 performs laser cleaning on the battery electrode 90. The controller 60, based on whether the battery electrode 90 is the first surface 91 or the second surface 92, and the inspection results, controls the laser cleaning unit 53 to precisely clean the battery electrode 90 using preset, targeted cleaning parameters. For example, a first cleaning parameter is used on the first surface 91 of the battery electrode 90 on the first carrier plate 121, and a second cleaning parameter is used on the second surface 92 of the battery electrode 90 on the second carrier plate 122, so as to ensure that the cleaning depth of different surfaces can meet the requirements and solve the problem of poor cleaning depth stability.

[0100] In some embodiments, when step S20 is performed in the laser cleaning apparatus, the controller 60 controls the detection mechanism 40 to alternately detect the first position information of the first surface 91 of the battery electrode 90 on the corresponding carrier plate 120 and the second position information of the second surface 92 of the battery electrode 90 on the corresponding carrier plate 120; and when step S30 is performed in the laser cleaning apparatus, the controller 60 controls the laser cleaning mechanism 50 to alternately clean the first surface 91 of the corresponding battery electrode 90 and the second surface 92 of the corresponding battery electrode 90. In other words, the laser cleaning apparatus provided in the embodiments of this application has only one detection mechanism 40 and one laser cleaning mechanism 50. For example, the battery electrode 90 placed on the first carrier plate 121 and the battery electrode 90 placed on the second carrier plate 122 are alternately moved to the second work station section 112 under the control of the controller 60. The controller 60 controls the detection mechanism 40 to perform alternating detection on the first surface 91 of the battery electrode 90 on the first carrier plate 121 or the second surface 92 of the battery electrode 90 on the second carrier plate 122. Correspondingly, the controller 60 controls the laser cleaning mechanism 50 to alternately clean the corresponding first surface 91 and the corresponding second surface 92 of the battery electrode 90. This forms a stable and efficient automated cleaning process, which helps to improve production efficiency.

[0101] In some embodiments, such as Figure 6As shown, when executing "Step S20: Detect the first surface 91 to determine the first position information of the first surface 91, and detect the second surface 92 to determine the second position information of the second surface 92", the detection mechanism 40 simultaneously detects and determines whether the battery electrode 90 is qualified. For battery electrode 90s that are determined to be qualified, the subsequent corresponding cleaning operation continues; for battery electrode 90s that are determined to be unqualified, the subsequent corresponding cleaning operation is terminated. That is: when the battery electrode 90 is determined to be qualified, the controller 60 controls the laser cleaning mechanism 50 to continue to perform the corresponding cleaning operation on the first surface 91 or the second surface 92 of the battery electrode 90 on the corresponding carrier plate 120; when the battery electrode 90 is determined to be unqualified, the controller 60 controls the corresponding carrier plate 120 to return and place the unqualified battery electrode 90 into the waste box 73, realizing the automatic sorting of unqualified products.

[0102] In some embodiments, such as Figure 6 As shown, the battery electrode cleaning method further includes the following step S40: After the corresponding cleaning operation is completed on the first surface 91 or the second surface 92 of the corresponding battery electrode 90, the controller 60 controls the detection mechanism 40 to detect the first surface 91 or the second surface 92 of the battery electrode 90 on the returned carrier plate 120 again, so as to determine whether the first surface 91 or the second surface 92 of the battery electrode 90 has been cleaned qualified. Specifically, when the first surface 91 or the second surface 92 of the corresponding battery electrode 90 is determined to be cleaned successfully, the controller 60 controls the gripping structure 30 of the laser cleaning device to grip and place the qualified battery electrode 90 into the corresponding unloading box 72, thereby realizing automated gripping and sorting and improving production efficiency; when the first surface 91 or the second surface 92 of the corresponding battery electrode 90 is determined to be cleaned unsuccessfully, the controller 60 controls the gripping structure 30 of the laser cleaning device to grip and place the unsuccessful battery electrode 90 into the waste box 73, thereby further realizing the automatic sorting of unqualified products.

[0103] This battery electrode cleaning method can separate battery electrodes 90 from different surfaces to be cleaned, and perform targeted inspection and cleaning. This effectively avoids the problem of traditional single-station equipment being unable to simultaneously address the cleaning depth of different surfaces, significantly improving the stability of the cleaning depth of the battery electrodes 90. Furthermore, automated gripping and sorting improves production efficiency and avoids the chaos and inefficiency that can result from manual placement of the battery electrodes 90.

[0104] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
