Detailed Implementation
[0022] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.
[0023] Example: A dual-beam laser welding device for thin plate welding, such as... Figures 1-3As shown, the assembly includes a mounting plate 1, an electric slide rail 2, a fixing plate 3, a mounting bracket 4, a guide rail 401, a controller 5, a fixing bracket 6, a laser head 7, a guide plate 8, a placement plate 9, a first elastic element 10, a pressure plate 11, and a second elastic element 12. The mounting plate 1 serves as the mounting carrier for the parts. An electric slide rail 2 is mounted on the upper side of the mounting plate 1, and an electric slider on the electric slide rail 2 is connected to the fixing plate 3. A mounting bracket 4 is welded to the rear side of the mounting plate 1, and a light is mounted on the upper side of the mounting bracket 4 for easy maintenance. The mounting bracket 4 is located directly behind the electric slide rail 2. A fixing bracket 6 is welded to the middle of the mounting bracket 4, and a guide rail 401 is connected to the fixing bracket 6. Controllers 5 are symmetrically mounted on the mounting bracket 4, and laser heads 7 are symmetrically connected to the fixing bracket 6. The two laser heads 7 are respectively connected to... The corresponding controller 5 is electrically connected and located above the fixed plate 3. The fixed plate 3 is symmetrically connected to the front and back of the guide plate 8. The guide plate 8 is slidably connected to the placement plate 9. The upper side of the placement plate 9 is connected to the protective pad to increase the friction between the placement plate 9 and the thin plate. The guide plate 8 and the placement plate 9 are symmetrically connected to each other. The lower part of the fixed plate 3 is symmetrically connected to the pressure plate 11 and the second elastic element 12. The two pressure plates 11 and the fixed plate 3 are symmetrically connected to each other. The electric slide rail 2 is activated to drive the placement plate 9 to move and place the thin plate on the placement plate 9. The pressure plate 11 rotates under the gravity of the thin plate and contacts the surface of the thin plate, thereby fixing the thin plate. The welding parameters of the laser head 7 are controlled by the controller 5 to achieve welding of the thin plate.
[0024] like Figures 4-5 As shown, it also includes a water tank 13, a cooler 1301, a cooling plate 14, a first water pump 15, a second water pump 16, a first water pipe 1601, and a second water pipe 17. The water tank 13 is connected to the mounting bracket 6 and is located between the guide rail 401 and the controller 5. The cooler 1301 is installed on the rear side of the water tank 13. The two laser heads 7 are symmetrically connected to the cooling plates 14 on one side facing each other. The first water pump 15 is installed between the upper parts of the two guide plates 8 and is fluidly connected to the two cooling plates 14. A second water pump 16 is installed between the lower parts. The second water pump 16 is fluidly connected to the two cooling plates 14. A first water pipe 1601 is connected between the water tank 13 and the second water pump 16. A second water pipe 17 is connected between the water tank 13 and the first water pump 15. When the cooler 1301 is started, the water in the water tank 12 is cooled. When the first water pump 15 is started, the water is pumped into the cooling plate 14 through the second water pipe 17. The cooling plate transfers temperature to the laser head 7. When the second water pump 16 is started, the water is pumped back to the water tank through the first water pipe 1601 for recycling.
[0025] like Figure 6As shown, it also includes a placement box 18, a protective door 19, and counterweights 20. The placement box 18 is welded to the lower side of the mounting plate 1. The protective door 19 is symmetrically and rotatably connected to the front side of the placement box 18. Four counterweights 20 are welded to the lower side of the placement box 18. The four counterweights 20 are arranged in a rectangular shape. The placement box 18 is used to place tools.
[0026] like Figure 7 As shown, it also includes a motor 21, a connecting plate 22, a screw 23, a moving plate 24, a protective plate 25, and a cylinder 26. The motor 21 is symmetrically mounted on the lower side of the placement box 18 by bolts. The connecting plate 22 is welded to the lower part of the left and right sides of the placement box 18. The screw 23 is rotatably connected to the connecting plate 22. The upper ends of the output shafts of the two motors 21 are connected to the adjacent screw 23 through couplings. The moving plate 24 is threadedly connected to the screw 23. The two moving plates 24 are in contact with the placement box 18 on opposite sides. The protective plates 25 are welded to the two moving plates 24. The two protective plates 25 are both U-shaped. The cylinder 26 is mounted on the moving plate 24. The telescopic rods of the two cylinders 26 are respectively connected to the adjacent protective plates 25 at opposite ends. Starting the motor 21 drives the protective plate 25 to adjust its height. Starting the cylinder 26 drives the two protective plates 25 to move downward to wrap around the thin plate and block debris.
[0027] When this device is needed, the electric slide rail 2 is activated. The slider on the electric slide rail 2 moves, causing the fixed plate 3 to move forward. The fixed plate 3 moves the guide plate 8, the placement plate 9, the first elastic element 10, and the pressure plate 11, placing the thin plate onto the placement plate 9. The protective pad increases the friction between the thin plate and the placement plate 9. Under the weight of the thin plate, the placement plate 9 moves downward and contacts the pressure plate 11. The first elastic element 10 deforms adaptively, causing the pressure plate 11 to rotate in the opposite direction and contact the surface of the thin plate. The second elastic element 12 deforms adaptively, and the thin plate is fixed by the cooperation of the placement plate 9 and the pressure plate 11. Subsequently, the slider on the electric slide rail 2 is controlled to move in the opposite direction. The aforementioned components are reset, and the moving laser head 7 is moved to above the thin plate. The laser head 7 drives the cooling plate 14, the first water pump 15, and the second water pump 16 to move. Then, the welding parameters of the laser head are controlled by the controller 5 to perform welding operations on the thin plate. Before the welding operation, the motor 21 is started. The output shaft of the motor 21 rotates, driving the screw 23 to rotate. The screw 23 drives the moving plate 24, the cylinder 26, and the protective plate 25 to move upward. The moving plate 24 guides the protective plate 25. After the two protective plates 25 are moved to both sides of the thin plate, the motor 21 is stopped, and the cylinder 26 is started. The telescopic rod of the cylinder 26 extends, causing the protective plates 25 to move towards each other. Wrapping the thin plate helps to block the flying debris during welding, providing protection. After welding, the cooler 1301 and the first water pump 15 are activated sequentially. The cooler 1301 cools the water in the water tank 13, and the first water pump 15 circulates the cooled water from the water tank 13 to the cooling plate 14 through the second water pipe 17. The cooling plate 14 then transfers the temperature to the laser head 7, cooling the welded laser head 7. After cooling, the control cylinder 26 extends its telescopic rod, causing the two protective plates 25 to move in opposite directions. Then, the control motor 21 rotates in the opposite direction, causing the screw 23 to rotate in the opposite direction. The screw 23 resets the corresponding components, and the motor 21 is turned off. Start the second water pump 16. The second water pump 16 transports the water in the cooling plate 14 back to the water tank 13 through the first water pipe 1601, thereby realizing the recycling. Move the thin plate to either the left or right to disengage it from the placement plate 9 and the pressure plate 11. The first elastic element 10 and the second elastic element 12 return to their original state. The placement plate 9 and the pressure plate 11 are reset under the elastic force of the first elastic element 10 and the second elastic element 12, respectively. The placement frame can be used to place welding tools. The protective door 19 protects them. When performing maintenance at night, the lighting can be turned on to facilitate maintenance. For subsequent welding operations on the thin plate, the above operations can be repeated.
