[0002] A green laser welding device for copper is a device specifically designed for efficient and high-quality welding of copper (pure copper). This device mainly uses green laser with a wavelength of 500 - 550 nanometers as the heat source because green laser has unique advantages when dealing with high-reflectivity materials such as copper.

[0003] During the laser welding process of the green laser welding device, it is necessary to effectively clean the surface of copper at the same time to remove the oxide layer, oil stains and other impurities, so as to ensure the welding quality. However, most of the existing green laser welding devices do not have an integrated cleaning function, resulting in the need to rely on manual or additional equipment for pretreatment before welding, which not only increases the operation steps and time costs, but also may affect the accuracy and stability of laser welding due to incomplete cleaning, reducing the strength and reliability of the welded joint.

[0004] In view of the above problems, it is necessary to provide a green laser welding device for copper with a cleaning function. Summary of the Invention

Detailed Description of the Embodiment

[0025] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0026] Embodiment: A green laser welding device for copper, as Figures 1 - 8As shown in the figure, it includes a cabinet 1, a first electric slide rail 2, a first slider 3, a sliding plate 4, a second electric slide rail 5, a second slider 6, a fixture assembly 7, a robotic arm 8, a laser welding head 801, a mounting plate 9, a first electric push rod 10, a connecting frame 11, a motor 12, a cleaning rod 13, a mounting frame 14, a collection box 15, a connecting plate 16, a second electric push rod 17, a baffle 18, a temperature sensor 19, an inert gas connector 20, a grating 21, and anti-slip foot supports 22. Inside the cabinet 1, multiple first electric slide rails 2 are evenly spaced and installed. A first slider 3 is slidably connected to each of the multiple first electric slide rails 2. A sliding plate 4 is connected to each pair of adjacent first sliders 3 on the left and right. Multiple mounting holes are provided on both sliding plates 4. Second electric slide rails 5 are symmetrically installed in the front and back on both sliding plates 4. A second slider 6 is slidably connected to each of the multiple second electric slide rails 5. A fixture assembly 7 is installed on each pair of second sliders 6 on the same side on the left and right. A robotic arm 8 is installed inside the cabinet 1, and a laser welding head 801 is installed on the robotic arm 8. Mounting plates 9 are symmetrically installed on the left and right of the cabinet 1. First electric push rods 10 are symmetrically installed in the front and back on both mounting plates 9. A connecting frame 11 is connected between the telescopic ends of the first electric push rods 10 on the same side on the left and right. A motor 12 is installed on each of the two connecting frames 11. A cleaning rod 13 is installed on the output shaft of each of the two motors 12. The telescopic movement of the first electric push rod 10 can drive the connecting frame 11, the motor 12, and the cleaning rod 13 to move up and down, adjusting the position of the cleaning rod 13 in the appropriate vertical direction. The other ends of the two cleaning rods 13 are rotatably connected to the corresponding connecting frames 11, which are used to clean the surface of the area to be welded, improving the welding accuracy and bonding strength. Mounting frames 14 are installed on both fixture assemblies 7, and collection boxes 15 are placed inside both mounting frames 14, which are used to centrally collect the impurities and debris that fall during the cleaning process, keeping the working environment clean. A connecting plate 16 is installed on the cabinet 1. Second electric push rods 17 are symmetrically installed on the left and right of the connecting plate 16. Baffles 18 are installed at the telescopic ends of the two second electric push rods 17, providing effective isolation and protection for the laser welding area. A temperature sensor 19 is installed on the laser welding head 801, which can monitor the temperature change in the welding area in real time, and the feedback data is used by the control system to adjust the laser power to prevent overheating from damaging the material. An inert gas connector 20 is installed on the temperature sensor 19, which is connected to an inert gas supply source to spray inert gases such as argon into the welding area to prevent metal oxidation and improve the welding quality. Gratings 21 are symmetrically installed on the left and right of the cabinet 1. When a person or foreign object is detected entering the dangerous area, the device will immediately stop running to ensure the safety of the operator. Anti-slip foot supports 22 are symmetrically connected to the front and back of the bottom of the cabinet 1, which are distributed left and right, preventing the device from sliding or tipping during operation and ensuring safe and reliable operation.

[0027] When laser welding of red copper is required, the staff first start multiple first electric slide rails 2, drive their respective first sliders 3 to move forward, and drive the sliding plates 4 and fixture assemblies 7 thereon to move together. After the fixture assembly 7 reaches the appropriate position, the first electric slide rails 2 are turned off. Subsequently, the red copper to be welded is placed on the fixture assembly 7 and fixed and clamped by the fixture assembly 7. After the clamping is completed, multiple first electric slide rails 2 are started again to drive the first sliders 3 to reset. During this process, two motors 12 are started simultaneously. The output shafts of the motors 12 drive the cleaning rods 13 to rotate counterclockwise. When the first sliders 3 are reset, the cleaning rods 13 are located directly above the red copper and start to clean its surface. At the same time, multiple second electric slide rails 5 are started to drive the second sliders 6 to move reciprocally, thereby driving the fixture assembly 7 and the red copper thereon to move back and forth under the cleaning rods 13 to achieve comprehensive cleaning. The impurities generated during the cleaning process will fall into the collection box 15 and be centrally collected by the collection box 15. After the surface cleaning is completed, the two motors 12 and all the second electric slide rails 5 are turned off. Subsequently, the inert gas connector 20 is externally connected to the gas supply device, and two second electric push rods 17 are started. Their telescopic ends drive the baffle 18 to move downward. When the baffle 18 reaches the designated position, the second electric push rods 17 are turned off. At this time, the baffle 18 can effectively isolate the laser welding area and prevent splashing from affecting the surrounding environment. That is, when adjusting the first electric slide rails 2, second electric slide rails 5, cleaning rods 13 and fixture assemblies 7 to the appropriate positions in the early stage, the second electric push rods 17 can telescopically drive the baffle 18 to move upward so that the operator can better see whether the components of these devices are in the appropriate positions. After adjusting these components to the appropriate positions, the second electric push rods 17 are then telescoped to drive the baffle 18 to move downward so that the baffle 18 can effectively isolate the laser welding area and prevent splashing from affecting the surrounding environment.

[0028] Next, start the robotic arm 8 and the laser welding head 801. The robotic arm 8 controls the laser welding head 801 to precisely weld the red copper. During the welding process, the gas supply device is synchronously turned on, and inert gas is conveyed to the welding area through the inert gas connector 20 to prevent the metal from oxidizing due to high temperature, improve the welding quality and remove the surrounding impurity gases. At the same time, the temperature sensor 19 continuously monitors the working temperature of the laser welding head 801 to ensure precise heat control during the welding process. After the welding is completed, the robotic arm 8 and the laser welding head 801 are turned off, and two second electric push rods 17 are started again to drive the baffle 18 to reset. After the baffle 18 is completely reset, the second electric push rods 17 are turned off. Finally, multiple first electric slide rails 2 are started again to drive the first sliders 3 to drive the fixture assembly 7 and the welded red copper forward. When the red copper moves into place, the fixture assembly 7 is loosened, and the welded workpiece can be taken out.
