Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a laser cleaning device and a battery cell electrode processing equipment. Background Technology

[0002] Current battery cell terminal cleaning processes mainly employ mechanical grinding, chemical cleaning, or traditional laser cleaning methods. Mechanical grinding removes the oxide layer through physical contact, but it easily produces metal shavings and scratches on the terminal surface, affecting the quality of subsequent welding. Chemical cleaning relies on solvents or acidic solutions, which can achieve surface cleaning, but it presents challenges in waste liquid treatment and environmental pollution risks, and requires an additional drying process after cleaning.

[0003] While traditional laser cleaning offers the advantage of being non-contact, it is limited by insufficient positioning system accuracy, making it difficult to meet the precise focusing requirements of electrodes at different heights. This can easily lead to uneven laser energy distribution, affecting the cleaning effect. Furthermore, most systems lack integrated real-time dust collection devices, allowing contaminants generated during cleaning to re-adhere to the electrode surface, resulting in poor cleaning performance. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a laser cleaning device and a battery cell electrode processing equipment, which solves the technical problems of poor positioning accuracy and easy adhesion of laser cleaning contaminants to the electrode in traditional laser cleaning technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: This invention provides a laser cleaning device, comprising a laser, a mounting base, and a three-dimensional positioning component, a laser cleaning component, and a dust collection component mounted on the mounting base. The three-dimensional positioning component includes a CCD camera and a laser rangefinder. The CCD camera acquires the position coordinates of the battery cell electrode in the X and Y axes, and the laser rangefinder acquires the position coordinates of the battery cell electrode in the Z axis. The laser cleaning component includes a laser cleaning lens, which focuses the laser beam emitted by the laser onto the battery cell electrode. The dust collection component includes a suction tube and a fixing component. The suction tube is mounted on the mounting base via the fixing component. One end of the suction tube is connected to a vacuum cleaner, and the other end of the suction tube is correspondingly positioned with respect to the battery cell electrode for removing contaminants generated during the laser cleaning process.

[0006] In one possible implementation, the three-dimensional positioning component further includes a mounting plate and a camera fixture, the mounting plate being mounted on the mounting base, the camera fixture being mounted on the mounting plate, and the CCD camera being mounted on the camera fixture.

[0007] In one possible implementation, the three-dimensional positioning component further includes a camera auxiliary connector and an adapter, the camera auxiliary connector being mounted on the mounting base, and the end of the CCD camera furthest from the camera fixture being connected to the camera auxiliary connector via the adapter.

[0008] In one possible implementation, the three-dimensional positioning component further includes a rangefinder connector mounted on the mounting base, wherein the laser rangefinder is mounted on the mounting base via the rangefinder connector.

[0009] In one possible implementation, the laser cleaning apparatus further includes a laser fixture mounted on the mounting base, the laser being mounted on the laser fixture.

[0010] In one possible implementation, the fixing component includes a vacuum hose adapter and a vacuum hose fixing component, wherein the vacuum hose adapter is mounted on the mounting base, the vacuum hose is fixedly mounted on the vacuum hose fixing component, and the vacuum hose adapter is connected to the vacuum hose fixing component.

[0011] This utility model also provides a battery cell electrode processing equipment, including the laser cleaning device described above.

[0012] The beneficial effects of this utility model are that, compared with the prior art, this utility model achieves accurate coordinate acquisition of the battery cell electrode in the X, Y, and Z axes through a three-dimensional positioning component, ensuring accurate positioning of the laser focus, and, combined with a dust collection component, removes contaminants in real time during the cleaning process, effectively avoiding secondary pollution. This avoids poor cleaning results caused by insufficient positioning accuracy and secondary pollution of contaminants during the cleaning of the battery cell electrode, thus solving the technical problems of poor positioning accuracy and easy adhesion of laser cleaning contaminants to the electrode in traditional laser cleaning technology.

[0017] To solve the above-mentioned technical problems, this utility model provides a laser cleaning device and a battery cell electrode processing equipment. The technical solution and embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

Therefore, they should not be construed as limitations on this application.

[0019] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation", "connection" and "joining" should be interpreted broadly, for example, they can refer to fixed connection, detachable connection, or integral connection; for those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0020] The terms "first" and "second" 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 as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0021] like Figures 1 to 3As shown, this utility model provides a laser cleaning device, which includes a laser, a mounting base 1, and a three-dimensional positioning component, a laser cleaning component, and a dust collection component mounted on the mounting base 1. The three-dimensional positioning component includes a CCD camera 4 and a laser rangefinder 8. The CCD camera 4 is used to acquire the position coordinates of the battery cell electrode in the X and Y axes, and the laser rangefinder 8 is used to acquire the position coordinates of the battery cell electrode in the Z axis. The laser cleaning component includes a laser cleaning lens 10, which is used to focus the laser beam emitted by the laser onto the battery cell electrode. The dust collection component includes a dust collection tube 13 and a fixing component. The dust collection tube 13 is mounted on the mounting base 1 via the fixing component. One end of the dust collection tube 13 is connected to a vacuum cleaner, and the other end of the dust collection tube 13 is correspondingly positioned with respect to the battery cell electrode, used to remove contaminants generated during the laser cleaning process.

[0022] In practical applications, the CCD camera 4 can use an industrial-grade image sensor in conjunction with digital image processing algorithms to extract coordinates, such as determining the position of the electrode plane through feature point matching technology; the laser rangefinder 8 is used to obtain the position coordinates of the battery cell electrode in the Z-axis direction, which can be achieved using a non-contact optical ranging device, such as using the laser phase difference method to measure height changes.

[0023] Specifically, the laser cleaning lens 10 can be implemented using a fixed focal length optical lens or an electric focusing system, for example, by dynamically adjusting the focal position by driving the lens group with piezoelectric ceramic.

[0024] The fixing components can be achieved by using a flexible clamping structure or a vacuum adsorption method, such as using silicone clamps to fix the vacuum tube 13.

[0025] The end of the suction pipe 13 can be designed as a rotatable joint structure, for example, by adjusting the direction of the suction port through a ball hinge mechanism.

[0026] Therefore, this application achieves the separate acquisition of the three-dimensional coordinates of the battery cell electrode post through the independent operation of the CCD camera 4 and the laser rangefinder 8, ensuring that the laser beam can adapt to the surface contours of electrode posts of different heights. At the same time, the real-time operation of the dust collection component blocks the diffusion path of contaminants under airflow disturbance, thereby maintaining the cleanliness of the cleaned surface and providing a reliable foundation for subsequent welding processes.

[0027] Furthermore, the three-dimensional positioning component also includes a mounting plate 2 and a camera fixture 3. The mounting plate 2 is mounted on the mounting base 1, the camera fixture 3 is mounted on the mounting plate 2, and the CCD camera 4 is mounted on the camera fixture 3.

[0028] Among them, mounting plate 2 refers to the structural component used to construct the basic support layer. It can be made of metal sheet or composite material plate, and its purpose is to provide a rigid mounting interface to block the transmission of external vibration.

[0029] The camera mounting component 3 refers to the component used to adjust and lock the position of the CCD camera 4. It can be implemented by a slider-type adjustment mechanism or a magnetic fixing device. The purpose is to provide fine horizontal calibration capability and ensure positional stability during long-term operation.

[0030] Specifically, the solution of this application forms a stable foundation support layer through the fixed connection between the mounting plate 2 and the mounting base 1, effectively isolating the transmission of overall equipment vibration to the positioning components; the cooperation between the camera fixing component 3 and the mounting plate 2 introduces an intermediate adjustment link, allowing the CCD camera 4 to be finely adjusted in the horizontal plane to accurately match the field of view of the battery cell electrode. The rigid connection between the CCD camera 4 and the camera fixing component 3 simplifies the alignment operation while ensuring position locking, thereby forming a multi-level collaborative positioning guarantee mechanism to ensure the continuous accuracy of X-axis and Y-axis coordinate acquisition.

[0031] Furthermore, the three-dimensional positioning component also includes a camera auxiliary connector 5 and an adapter 6. The camera auxiliary connector 5 is mounted on the mounting base 1, and the end of the CCD camera 4 away from the camera fixing part 3 is connected to the camera auxiliary connector 5 through the adapter 6.

[0032] Among them, the camera auxiliary connector 5 refers to the structural component used to provide additional rigid support. It can be implemented by metal bracket or composite material bracket. The purpose is to avoid structural deformation or cumulative errors that may occur if only the mounting plate 2 is relied upon, so as to make the installation base of the entire positioning component more stable and reliable.

[0033] The adapter 6 can be understood as an adjustable connecting component, which can be implemented by using a threaded adjustment block or a flexible snap-fit ​​structure. Its purpose is to allow fine adjustments to adapt to different installation requirements, while suppressing the rotational or tilting freedom of the CCD camera 4 during operation.

[0034] Specifically, the solution in this application directly mounts the camera to the mounting base 1 via the camera auxiliary connector 5, providing a rigid support reference independent of the mounting plate 2. Simultaneously, the end of the CCD camera 4 furthest from the camera fixture 3 is connected to the camera auxiliary connector 5 via an adapter 6, forming a two-point fixing structure. This structure, based on the proximal fixing already achieved by the camera fixture 3, applies additional constraint to the distal end of the camera, effectively suppressing positional shifts caused by vibration or movement, thereby maintaining the continuity and accuracy of image capture and providing a stable positioning basis for laser cleaning.

[0035] Furthermore, the three-dimensional positioning component also includes a rangefinder connector 7 mounted on the mounting base 1, and a laser rangefinder 8 is mounted on the mounting base 1 via the rangefinder connector 7.

[0036] Among them, the rangefinder connector 7 refers to a special mechanical interface component used to fix the laser rangefinder 8. It can be implemented by a block structure, a bracket structure or a customized connector. Specifically, it can be a rigid connector made of metal. Its purpose is to provide a stable installation reference and avoid stress deformation or positional displacement caused by direct fixing.

[0037] The laser rangefinder 8 is installed via the rangefinder connector 7, which means that the laser rangefinder 8 is not directly fixed to the mounting base 1, but is indirectly installed through an intermediate connector. This can be achieved by means of threaded connection, snap-fit ​​connection or magnetic adsorption. Specifically, the laser rangefinder 8 can be fixed to the connector first, and then the connector can be fixed to the mounting base 1. The purpose is to facilitate fine-tuning and calibration and maintain the consistency between the measurement axis and the installation reference.

[0038] Specifically, the solution in this application forms a rigid connection point through the matching design of the rangefinder connector 7 and the mounting base 1, effectively suppressing the interference of external vibrations on height measurement. The laser rangefinder 8 is indirectly installed through the mediation of the rangefinder connector 7, ensuring that the measurement axis is consistent with the installation reference, thereby guaranteeing the continuity and accuracy of Z-axis coordinate acquisition. This structural combination eliminates the assembly deviation that may be caused by direct fixing of the laser rangefinder 8, providing a reliable basis for the precise focusing of the laser cleaning lens 10 on the surface of the pole at different heights, and ultimately realizing the stable measurement function of the three-dimensional positioning component in the height direction.

[0039] Furthermore, the laser cleaning device also includes a laser fixture 9 mounted on the mounting base 1, with the laser mounted on the laser fixture 9.

[0040] Among them, the laser fixture 9 refers to a rigid connection structure used to provide stable support. It can be implemented by metal brackets, elastic clamps or mounting platforms with shock-absorbing pads. Its purpose is to absorb external vibrations and resist the effects of thermal deformation, so as to ensure that the laser maintains a precise position during operation.

[0041] Mounting base 1 serves as the basic support structure. Its overall rigidity stems from the layout design of the integrated three-dimensional positioning component and dust collection component, which can effectively disperse external stress and prevent the laser from undergoing slight displacement in the X, Y, and Z axis directions.

[0042] Specifically, the connection between the laser fixture 9 and the mounting base 1 utilizes the overall rigidity of the mounting base 1. This rigidity is enhanced through the integrated layout of the three-dimensional positioning component and the dust collection component, thereby suppressing vibration transmission during equipment operation. Simultaneously, the rigid connection between the laser and the laser fixture 9 maintains the laser's initial positioning parameters, preventing focus drift due to loosening or thermal expansion. This ensures that the laser beam consistently and accurately acts on the surface of the battery cell electrode during the cleaning process, forming a complete positioning and cleaning synergy mechanism.

[0043] Furthermore, the fixing assembly includes a vacuum hose 13 adapter 116 and a vacuum hose 13 fixing member 12. The vacuum hose 13 adapter 116 is mounted on the mounting base 1, and the vacuum hose 13 is fixedly mounted on the vacuum hose 13 fixing member 12. The vacuum hose 13 adapter 116 is connected to the vacuum hose 13 fixing member 12.

[0044] Among them, the vacuum hose 13 adapter 116 refers to the transition component connecting the vacuum hose 13 and the mounting base 1. It can be implemented by adopting a dovetail groove structure or a threaded connection to provide high rigidity and stability and avoid the vacuum hose 13 from shifting position due to vibration or external interference.

[0045] The vacuum hose 13 fixing part 12 refers to the adjustment mechanism used to fix the vacuum hose 13. It can be implemented by an adjustable clamping mechanism or an elastic clamp. The purpose is to allow fine angle and distance adjustment of the vacuum hose 13 to adapt to the slight positional changes of the battery cell electrode during the three-dimensional positioning process.

[0046] Specifically, the vacuum tube 13 adapter 116 is directly mounted on the mounting base 1. Utilizing the high rigidity of the mounting base 1 as the foundation support platform for the entire device, the reference position of the end of the vacuum tube 13 relative to the battery cell electrode is ensured to be stable and reliable. The vacuum tube 13 fixing component 12 is fixedly connected to the vacuum tube 13. Its adjustable design allows for fine-tuning of the vacuum tube 13 in three-dimensional space, enabling the end of the vacuum tube 13 to dynamically adapt to battery cell electrodes of different heights and coordinates. The modular connection between the vacuum tube 13 adapter 116 and the vacuum tube 13 fixing component 12 ensures the overall rigidity of the structure to prevent loosening caused by airflow impact during cleaning, while also facilitating quick disassembly and maintenance. This maintains a stable correspondence between the vacuum tube 13 and the battery cell electrode during laser cleaning, forming a continuous and effective closed loop for contaminant collection.

[0047] This utility model also provides a battery cell electrode processing equipment, including the laser cleaning device described above.
