[0003] The existing laser welding protective room has the following technical defects when in use: First, the high-temperature gas generated during laser welding is often directly dissipated to the outside of the protective room through the heat dissipation mechanism, and the heat dissipation intensity of the heat dissipation mechanism cannot be adjusted according to the temperature during the welding process, resulting in blind heat dissipation of high temperature and affecting its heat dissipation effect; second, the stress generated by metal deformation during welding cannot be removed in time, resulting in metal deformation and even warping, which seriously affects the performance of the metal material. Summary of the invention

[0011] Preferably, the angle between the rotatable angle of the rotating shaft and the connecting arm of the laser emitter is between ° and °.

[0012] The present invention has the following beneficial effects: 1. The present invention welds metals through the radiation energy generated by the laser welding transmitter when it is working, so that the gas inside the heat conduction cavity expands and drives the limit plate to move to achieve the effect of controlling the heat dissipation intensity according to the heat temperature change during the welding process, thereby solving the problem of poor heat dissipation effect caused by blindly changing the heat dissipation intensity in the prior art.

[0013] 2. The present invention eliminates metal stress during the welding process by using ultrasonic waves emitted by an ultrasonic transmitter.

[0014] 3. The present invention uses the ultrasonic kinetic energy in the ultrasonic stress relief process to drive the swing of the limit plate to achieve heat dissipation, and uses the inherent properties of ultrasound to achieve the effect of timely heat dissipation. It can achieve effective heat dissipation without an external heat dissipation mechanism, and achieves the effect of heat dissipation while removing stress, so that the protective room has better stress relief and heat dissipation effects.

[0015] 4. The present invention uses the high temperature generated during the welding process to change the position of the conductive slider according to the degree of gas expansion caused by different temperatures. At the same time, different gear adjustments of the cooling fan are achieved through the contact between the conductive slider and the conductive sheet.

The ultrasonic wave emitted by the ultrasonic transmitter 8 acts on the metal surface during operation, and the effect of timely removing the metal stress during the welding process is achieved under the vibration of the ultrasonic wave. Since the ultrasonic wave can also be transmitted in the solid, the ultrasonic kinetic energy is transmitted to the inside of the welding table 9 through the metal surface, and then the rotating column 92 is rotated, and then the limit plate 93 is driven to swing. During the swinging process, the air flow inside the welding table 9 circulates, and the high-temperature gas inside the welding table 9 is further discharged to the outside of the welding table 9 through the through hole 91, which significantly enhances the heat dissipation effect of the protective room. The heat transfer mechanism includes a heat conduction cavity 101 opened inside the two heat conduction plates 10, and two pistons 102 are slidably connected to the left and right sides of the heat conduction cavity 101. The other ends of the two pistons 102 are slidably connected to two conductive sliders 103, and the other ends of the two conductive sliders 103 are fixedly connected to two springs 104, and the other ends of the two springs 104 are fixedly connected to the inner wall of the heat conduction plate 10, and the inner top wall of the heat conduction plate 10 is fixedly connected to a conductive sheet 105. The heat dissipation mechanism includes a rotating column 92 fixedly connected to the inner wall of the welding table 9, and the left and right ends of the rotating column 92 are rotatably connected to the limit plate 93. The front and rear side walls of the welding table 9 are provided with through holes 91. When working, first turn on the laser emitter 7 and the ultrasonic controller 4, adjust the rotating shaft 6 to align the laser emitter 7 with the metal to be welded, and perform welding. The ultrasonic wave emitted by the ultrasonic emitter 8 can eliminate the stress of the metal in time during the welding process. During the welding process, due to the huge heat generated by laser welding, the carbon dioxide gas filled in the heat-conducting cavity 101 inside the heat-conducting plate 10 is heated and expands rapidly, thereby pushing the pistons 102 on both sides, driving the conductive slider 103 to move, squeezing the spring 104, so that the conductive slider 103 is in contact with the conductive sheet 105 and energized, thereby driving the heat dissipation fan 3 to rotate, and the inside of the protective room is The gas is discharged in time to achieve the effect of heat dissipation. During the heat dissipation process, as the welding process continues, heat continues to accumulate, and the carbon dioxide gas inside the heat conduction cavity 101 continues to expand, driving the piston 102 to continue to move, so that the conductive slider 103 contacts the next adjacent conductive sheet 105, switching the gear of the cooling fan 3, increasing the speed, improving the heat dissipation effect, continuing welding, the speed of the cooling fan 3 is accelerated, and the heat dissipation effect is further enhanced. When the welding is completed, the heated gas is restored, and under the pulling force of the spring 104, the piston 102 and the conductive slider 103 are restored to the initial position, and the fan cooling system is closed.The interior of the two heat-conducting cavities 101 is filled with equal volumes of carbon dioxide gas. The conductive sheets 105 are arranged at equal intervals along the inner wall of the heat-conducting plate 10. Multi-gear heat dissipation switching is realized to ensure that the thermal expansion rate of the carbon dioxide gas is consistent with the sliding speed of the slider. The center of the ultrasonic transmitter 8 and the center of the rotating column 92 are kept on the same horizontal line in the vertical direction. The ultrasonic wave drives the limit plate 93 to swing in time. The rotatable angle of the rotating shaft 6 and the angle of the connecting arm of the laser transmitter 7 are between 0°-180°. It is convenient to realize the angle adjustment during the welding process.

[0020] The method of use (working principle) of the present invention is as follows: When working, first turn on the laser emitter 7 and the ultrasonic controller 4, adjust the rotating shaft 6 to align the laser emitter 7 with the metal to be welded, and then weld. The ultrasonic wave emitted by the ultrasonic emitter 8 can eliminate the stress of the metal in time during the welding process. During the welding process, due to the huge heat generated by laser welding, the carbon dioxide gas filled in the heat-conducting cavity 101 inside the heat-conducting plate 10 is heated and expands rapidly, thereby pushing the pistons 102 on both sides, driving the conductive slider 103 to move, squeezing the spring 104, so that the conductive slider 103 contacts the conductive sheet 105 and is energized, thereby driving the heat dissipation fan 3 to rotate, and the inside of the protective room is protected. The gas is discharged in time to achieve the effect of heat dissipation. During the heat dissipation process, as the welding process continues, heat continues to accumulate, and the carbon dioxide gas inside the heat conduction cavity 101 continues to expand, driving the piston 102 to continue to move, so that the conductive slider 103 contacts the next adjacent conductive sheet 105, switching the gear of the cooling fan 3, increasing the speed, improving the heat dissipation effect, continuing welding, the speed of the cooling fan 3 is accelerated, and the heat dissipation effect is further enhanced. When the welding is completed, the heated gas is restored, and under the pulling force of the spring 104, the piston 102 and the conductive slider 103 are restored to the initial position, and the fan cooling system is closed.

[0021] The ultrasonic wave emitted by the ultrasonic transmitter 8 acts on the metal surface when it is working. Under the vibration of the ultrasonic wave, the metal stress is removed in time during the welding process. Since the ultrasonic wave can also be transmitted in the solid, the ultrasonic kinetic energy is transmitted to the inside of the welding table 9 through the metal surface, and then the rotating column 92 rotates and then drives the limit plate 93 to swing. During the swinging process, the air flow inside the welding table 9 circulates, and the high-temperature gas inside the welding table 9 is further discharged to the outside of the welding table 9 through the through hole 91, which significantly enhances the heat dissipation effect of the protective room.
