Description

Technical Field

[0001] The utility model relates to the technical field of laser welding machines, in particular to a fast cooling laser welding machine. Background Art

[0002] A laser welder is a device that uses a laser as a heat source to melt and join two materials (usually metals or thermoplastics). Laser welding utilizes high-energy laser pulses to locally heat a small area of the material. The energy from the laser radiation diffuses into the material through heat conduction, melting the material and forming a specific molten pool.

[0003] When some laser welding machines work continuously for a long time, the large amount of heat generated during the welding process cannot be dissipated in time, resulting in excessive temperature in the welding area. Under high temperature conditions, the welding material is prone to excessive melting or oxidation, affecting the welding strength and appearance quality.

[0004] Therefore, it is urgent to propose a rapid cooling laser welding machine to solve the above technical problems. Utility Model Content

[0020] The above scheme is further described below with reference to specific examples.

[0021] Example: A rapid cooling laser welding machine, such as Figure 1-Figure 5As shown, it includes a machine base 1, an electric slide 2, a welding instrument 3, a guide rail 4, a slide 41, a workbench 5, a screw 6, a first motor 7, a second motor 71, a mounting frame 8, a bidirectional screw 9, a slide 10, a guide seat 11, a clamp 12 and a cooling unit. The machine base 1 serves as the basic structure of the entire laser welding machine, providing a stable support platform and integrating other components. An electric slide 2 is provided on the end face of the front part of the machine base 1. The electric slide 2 allows the welding instrument 3 to move smoothly on a predetermined path to ensure the accuracy of the welding position. The welding instrument 3 is slidably provided on the electric slide 2. The welding instrument 3 is the core component. , used to heat and melt the welding material to form a welding pool. Rear guide rails 4 are provided on both sides of the lower part of the machine base 1. The guide rails 4 provide a guide path for the slide 41 to ensure that the workbench 5 moves smoothly. Slides 41 are slidably provided on the guide rails 4 on both sides. The slide 41 slides along the guide rails 4 to support the workbench 5 and allow it to adjust its position in the welding area. A workbench 5 is provided between the sliders on both sides. The workbench 5 is used to fix the workpiece to be welded to ensure its stability during the welding process. A screw rod 6 is provided at the bottom of the workbench 5 for rotation. The screw rod 6 converts linear motion through rotation to make the workbench 5 It moves along the set trajectory, and a first motor 7 is provided at the rear part of the machine base 1. The output shaft of the first motor 7 is connected to the front screw rod 6. The first motor 7 drives the screw rod 6 to control the position adjustment of the workbench 5. A second motor 71 is provided on the top of one slide 41, and a mounting bracket 8 is provided on the rear side of the top of the workbench 5. The mounting bracket 8 fixes the second motor 71 and the bidirectional screw 9 to provide support for the slide 10. One side of the mounting bracket 8 is connected to the second motor 71, and the output shaft of the second motor 71 passes through the interior of the mounting bracket 8. A bidirectional screw 9 is rotatably provided inside the mounting bracket 8, and the bidirectional screw 9 is connected to the output shaft of the second motor 71. Then, the second motor 71 drives the bidirectional screw 9 to rotate, controls the movement of the slide 10, and further controls the clamping and loosening action 71 of the clamping block 12. Slides 10 are threaded on both sides of the bidirectional screw 9, and a guide seat 11 is provided at the middle and rear part of the top of the workbench 5. The front inner parts of the slides 10 on both sides are slidably connected with the guide seat 11 in front. A clamping block 12 is provided at the front end of the slide 10, and a cavity is provided inside the clamping block 12. Grooves corresponding to the welding elements are provided on the opposite end faces of the clamping blocks 12 on both sides. A cooling part for cooling the welding elements is provided between the upper part of the machine base 1 and the clamping block 12. This part is the first place.

[0022] like Figure 1-Figure 5As shown, the cooling unit includes a semiconductor radiator 14, a water tank 15, a water pump 16, a water supply pipe 17 and a return pipe 18. A semiconductor radiator 14 is provided on the top of the base 1. The semiconductor radiator 14 assists the water cooling system to improve the cooling efficiency. A water tank 15 is provided on the top of the base 1. The water tank 15 stores cooling water and provides a water source. The water tank 15 is connected to the semiconductor radiator 14 above. A water pump 16 is provided on one side of the upper part of the base 1. The water pump 16 circulates cooling water to ensure smooth water flow. The water pump 16 is connected to one side of the water tank 15. A water supply pipe 17 is connected to the water pump 16. The water supply pipe 17 transports cooling water to the inside of the clamp 12 to help absorb heat. A convex block is provided on the top of the mounting frame 8. The convex block supports the middle part of the water supply pipe 17. The water supply pipe 1 7 forks out at two places, and the output ends of the two forked parts are respectively connected to the cavities in the two clamps 12. The other side of the water tank 15 is connected to a return pipe 18. The lower part of the return pipe 18 is also connected to the output end of the water supply pipe 17. The return pipe 18 brings the water after absorbing heat back to the water tank 15 to complete the cooling cycle. The water supply pipe 17 and the return pipe 18 are both composed of silicone hoses with telescopic function. Water is output from the water pump 16 to the water supply pipe 17 and is sequentially introduced into the interior of the clamps 12 on both sides. Then, the clamps 12 on both sides clamp the welding elements at the same time. The heat generated during welding is conducted to the surface of the clamp 12 and to its interior, causing the water temperature of the water flowing through the clamp 12 to rise, and the heated water eventually returns to the water tank 15 through the return pipe 18 to form a cooling cycle.

[0023] like Figure 4 As shown, the cooling part also includes an air-cooled radiator 13. The air-cooled radiator 13 is set at the bottom of the workbench 5. This part is the second place. The air-cooled radiator assists the water cooling system to cool the workbench, maintain temperature coordination and balance, and ensure efficient operation of the system.

[0024] During use, the operator places the component to be welded on the workbench 5, which is supported by the slide 41 and connected to the first motor 7 through the screw rod 6. The operator controls the first motor 7 to move the workbench 5 to the appropriate position, and the welding instrument 3 on the electric slide 2 moves to the correct position according to the program instructions, ready for welding operation. After the second motor 71 is started, it drives the bidirectional screw 9 to rotate. Since the threads on both sides of the bidirectional screw 9 are in opposite directions, the slides 10 on both sides will move toward each other until the clamp 12 touches the component to be welded. The groove on the clamp 12 matches the welding component to ensure that the component is firmly clamped. This process ensures that the component will not be displaced due to thermal stress during welding. After the water pump 16 is started, water is drawn from the water tank 15 and transported to the cavity inside the clamps 12 on both sides through the water supply pipe 17. The water flows inside the clamp 12 and absorbs the heat generated during the welding process. During this period, the clamp 1 2 acts as a heat exchange medium, transferring heat from the welding element to the water flowing inside. The laser beam emitted by the welding device 3 is aimed at the welding point. The high-energy-density laser beam instantly heats the welding area, causing the material to reach a molten state and form a molten pool. As welding progresses, heat is continuously generated and conducted to the surrounding area. However, since the water in the clamp 12 continuously carries away heat, the welding area can be maintained in a suitable working temperature range. As the water temperature gradually rises, it returns to the water tank 15 through the return pipe 18. During this process, if the workbench temperature is too high, it can also be assisted by the air-cooled radiator 13 to cool it down. After the water is cooled again in the water tank 15, it is circulated back to the clamp 12 through the water pump 16, forming a closed cooling circulation system. When welding is completed, all motors and water pumps 16 are turned off, the clamp 12 is released to release the welding element, and the operator removes the welded parts from the workbench 5, and the entire welding process is completed.
