Description

Technical Field

[0001] This application relates to the field of laser technology, and more particularly to a green laser welding apparatus for copper. Background Technology

[0002] The green laser welding device for copper is a specialized device designed for efficient and high-quality welding of copper (pure copper). This device mainly uses a green laser with a wavelength of 500-550 nanometers as a heat source because green lasers have unique advantages in processing highly reflective materials such as copper.

[0003] During the laser welding process in a green laser welding device, the surface of the copper needs to be effectively cleaned to remove oxide layers, oil stains, and other impurities to ensure welding quality. However, most existing green laser welding devices do not have integrated cleaning functions, which means that pretreatment must be done manually or with additional equipment before welding. This not only increases the number of operation steps and time costs, but may also affect the accuracy and stability of laser welding due to incomplete cleaning, reducing the strength and reliability of the welded joint.

[0004] To address the aforementioned issues, there is a need for a green laser welding device for copper with a cleaning function. Utility Model Content

[0005] To overcome the drawback of lacking a cleaning function, this application provides a green laser welding device for copper.

[0006] The technical solution of this application is as follows: A green laser welding device for copper includes a cabinet, a first electric slide rail, a first slider, a sliding plate, a second electric slide rail, a second slider, a clamping assembly, a robotic arm, and a laser welding head. Multiple first electric slide rails are evenly spaced inside the cabinet, and first sliders are slidably connected to each of the multiple first electric slide rails. A sliding plate is connected to each pair of adjacent first sliders on the left and right sides. Second electric slide rails are symmetrically installed on each of the two sliding plates, and second sliders are slidably connected to each of the multiple second electric slide rails. A clamping assembly is installed on each of the two second sliders on the same left and right side. A robotic arm is installed inside the cabinet, and a laser welding head is installed on the robotic arm. The device also includes a mounting plate, first electric push rods, a connecting frame, a motor, and cleaning rollers. Mounting plates are symmetrically installed on the left and right sides of the cabinet. First electric push rods are symmetrically installed on each of the two mounting plates, front and back. A connecting frame is connected between the telescopic ends of two first electric push rods on the same left and right side. A motor is installed on each of the two connecting frames, and a cleaning roller is installed on the output shaft of each of the two motors. The other ends of the two cleaning rollers are rotatably connected to the connecting frames at corresponding positions.

[0007] Furthermore, it also includes mounting brackets and collection boxes, with mounting brackets mounted on both fixture assemblies and collection boxes placed inside both mounting brackets.

[0008] Furthermore, it also includes a connecting plate, a second electric push rod, and a baffle. The connecting plate is installed on the cabinet, and the second electric push rods are symmetrically installed on the left and right sides of the connecting plate. Both extension ends of the two second electric push rods are equipped with baffles.

[0009] Furthermore, it also includes a temperature sensor, which is installed on the laser welding head.

[0010] Furthermore, it also includes an inert gas connector, which is installed on the temperature sensor.

[0011] Furthermore, it also includes gratings, with gratings installed symmetrically on the left and right sides of the cabinet.

[0012] Furthermore, it also includes anti-slip feet, with anti-slip feet symmetrically connected to the front and back of the bottom of the cabinet and distributed on the left and right.

[0013] Furthermore, multiple mounting holes are provided on both sliding plates.

[0014] The beneficial effects of this application are as follows: 1.

[0015] 2. By setting up the connecting plate, the second electric push rod, and the baffle, the laser welding area is effectively isolated and protected, ensuring the safety and stability of the welding process.

Detailed Implementation

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

[0026] Example: A green laser welding apparatus for copper, such as... Figures 1-8As shown, the system 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 clamp 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 roller 13, a mounting frame 14, a collection frame 15, a connecting plate 16, a second electric push rod 17, a baffle 18, a temperature sensor 19, an inert gas connector 20, a light grating 21, and anti-slip feet 22. Multiple first electric slide rails 2 are evenly spaced inside the cabinet 1. Each of the multiple first electric slide rails 2 is slidably connected to a first slider 3. Each pair of adjacent first sliders 3 on the left and right sides is connected to a sliding plate 4. Each of the two sliding plates 4 has multiple mounting holes. Second electric slide rails 5 are symmetrically mounted on each of the two sliding plates 4, and second sliders 6 are slidably connected to each of the multiple second electric slide rails 5. Clamping assemblies 7 are mounted on the two second sliders 6 on the same side. A robotic arm 8 is installed inside the cabinet 1, and a laser welding head 801 is mounted on the robotic arm 8. Mounting plates 9 are symmetrically mounted on the cabinet 1, and first electric push rods 10 are symmetrically mounted on the two mounting plates 9, one in front of the other. A connecting frame 11 connects the telescopic ends of the two first electric push rods 10 on the same side, and a motor 12 is mounted on each of the two connecting frames 11. A cleaning roller 13 is mounted 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 roller 13 to move up and down, adjusting the cleaning roller 13 to a suitable vertical position. The other ends of the two cleaning rollers 13 are rotatably connected to the corresponding connecting brackets 11, used to clean the surface of the area to be welded, improving welding accuracy and bonding strength. Each of the two clamping assemblies 7 is equipped with a mounting bracket 14, and each mounting bracket 14 contains a collection frame 15 to collect impurities and debris that fall during the cleaning process, keeping the working environment clean. A connecting plate 16 is installed on the cabinet 1, and second electric push rods 17 are symmetrically installed on the connecting plate 16. Baffles 18 are installed at the telescopic ends of both second electric push rods 17 to effectively isolate and protect the laser welding area. A temperature sensor is installed on the laser welding head 801. The device 19 monitors the temperature changes in the welding area in real time, and the feedback data is used to control the system to adjust the laser power to prevent overheating and damage to the material. An inert gas connector 20 is installed on the temperature sensor 19 to connect to an inert gas supply source and spray inert gases such as argon into the welding area to prevent metal oxidation and improve welding quality. Optical gratings 21 are symmetrically installed on the left and right sides of the cabinet 1. When a human or foreign object is detected entering the danger zone, the equipment will stop immediately to ensure the safety of the operator. Anti-slip feet 22 are symmetrically connected to the front and back of the bottom of the cabinet 1 to prevent the device from sliding or tipping over during operation and to ensure safe and reliable operation.

[0027] When laser welding is required on copper, the operator first activates multiple electric slide rails 2, driving their respective first sliders 3 forward, which in turn moves the sliding plates 4 and clamping assemblies 7 on them. Once the clamping assembly 7 reaches the appropriate position, the electric slide rails 2 are deactivated. The copper to be welded is then placed on the clamping assembly 7 and clamped in place. After clamping, the electric slide rails 2 are activated again, driving the first sliders 3 to reset. During this process, two motors 12 are simultaneously activated, their output shafts driving the cleaning roller 13 to rotate counterclockwise. When the first slider 3 has reset, the cleaning roller 13 is positioned directly above the copper, and cleaning of its surface begins. During the cleaning process, multiple second electric slide rails 5 are activated, driving the second slider 6 to reciprocate, thereby causing the clamp assembly 7 and the copper on it to move back and forth below the cleaning roller 13 for comprehensive cleaning. Impurities generated during the cleaning process will fall into the collection frame 15 and be collected by the collection frame 15. After the surface cleaning is completed, the two motors 12 and all second electric slide rails 5 are turned off. Then, the inert gas connector 20 is connected to the gas supply device, and the two second electric push rods 17 are activated. 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 splashes from affecting the surrounding environment. In the initial stage, when adjusting the first electric slide rail 2, the second electric slide rail 5, the cleaning roller 13, and the clamp assembly 7 to the appropriate position, the second electric push rod 17 can extend and retract to move the baffle 18 upward, allowing the operator to better see whether the components of these devices are in the appropriate position. After adjusting these components to the appropriate position, the second electric push rod 17 extends and retracts to move the baffle 18 downward, so that the baffle 18 can effectively isolate the laser welding area and prevent spatter from affecting the surrounding environment.

[0028] Next, the robotic arm 8 and laser welding head 801 are activated. The robotic arm 8 controls the laser welding head 801 to precisely weld the copper. During the welding process, the gas supply device is simultaneously activated, supplying inert gas to the welding area through the inert gas connector 20 to prevent metal oxidation due to high temperature, improve welding quality, and remove surrounding impurities. At the same time, the temperature sensor 19 monitors the working temperature of the laser welding head 801 in real time to ensure precise heat control during the welding process. After welding is completed, the robotic arm 8 and laser welding head 801 are shut down, and the two second electric push rods 17 are activated again to reset the baffle 18. After the baffle 18 has fully reset, the second electric push rods 17 are shut down. Finally, the multiple first electric slide rails 2 are activated again to drive the first slider 3 to move the clamp assembly 7 and the welded copper forward. Once the copper has moved into position, the clamp assembly 7 is released, and the welded workpiece can be removed.
