Description

Technical Field

[0001] This invention relates to the field of welding technology, and in particular to a laser welding device with automatic angle adjustment. Background Technology

[0002] Laser welding is a highly efficient and precise welding method that utilizes a high-energy-density laser beam as a heat source. It is a crucial application of laser materials processing technology. In the 1970s, it was primarily used for welding thin-walled materials and low-speed welding. The welding process is heat conduction type; the laser radiation heats the workpiece surface, and the surface heat diffuses inward through heat conduction. By controlling parameters such as the laser pulse width, energy, peak power, and repetition frequency, the workpiece melts, forming a specific molten pool. Due to its unique advantages, it has been successfully applied to the precision welding of micro and small parts.

[0003] When laser welding is performed, a certain force is applied to the metal surface, causing some metal to separate from the processed parts, creating high-temperature particles that are sprayed in all directions. When these high-temperature particles come into contact with the human body, they can cause harm and endanger the lives of workers. Furthermore, these high-temperature particles are not collected when they fall, further creating metal waste and polluting the environment. In order to protect the lives of workers and control metal waste pollution, we propose the following solutions. Summary of the Invention

[0004] This invention discloses a laser welding device with automatic angle adjustment, which aims to solve the technical problems of high-temperature particulate matter generated during laser welding causing harm to the human body and metal waste gas causing environmental pollution.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatically adjustable laser welding device includes a housing. Support columns are movably connected to the outer walls of both sides of the housing. Baffles are movably connected to the inner walls of both sides of the support columns. Each baffle includes a connecting piece and is connected to a support rod via the connecting piece. A flow guide plate is provided on the bottom outer wall of the baffle, and a protective mirror is provided on the other outer wall of the baffle. A limiting plate is provided on the top outer wall of the housing and is also connected to the support rod. A slot is provided on the top inner wall of the housing, and a collection basket is provided on the inner wall of the slot. Multiple drainage holes are evenly spaced on the bottom inner wall of the collection basket. A sealing gasket is provided on one outer wall of the collection basket. A ventilation pipe is fixedly connected to one inner wall of the slot, and a suction fan is fixedly connected to one inner wall of the ventilation pipe.

[0007] By incorporating baffles, deflectors, protective goggles, collection baskets, drains, and a suction fan, the system effectively protects workers from the impact of laser welding on the metal surface, which generates high-temperature particles that can splatter upon contact with the human body. The baffles, goggles, and deflectors effectively block these particles from multiple directions, and the angled deflectors and baffles direct the particles into the collection baskets. Simultaneously, the suction fan collects smaller particles within the work area through ventilation pipes and drains. This system provides comprehensive protection for workers and facilitates the collection and recycling of these particles, reducing pollution from metal waste and minimizing cost waste.

[0008] In a preferred embodiment, an air outlet is provided on one inner wall of the suction fan, and an air purifier is sleeved on the outer wall of the ventilation pipe.

[0009] Laser welding produces a large amount of toxic gases and fumes, which can directly harm the health of workers if they are exposed to such a working environment for a long time. The ventilator absorbs the toxic gases and fumes generated during laser welding through ventilation pipes and holes, thereby purifying the welding environment and protecting the health of the workers.

[0011] By incorporating a turbine, screw, and connecting frame, with the connecting frame fixed to one side of the welding gun and the movable center of the welding gun tip fixed by a second connecting frame, the welding angle of the welding gun can be changed by the turbine moving on the screw and the sixth connecting frame, thereby achieving various welding purposes.

When the welding gun height needs to be adjusted, the limit screw can be unscrewed, and the position of the second connecting frame can be adjusted to change the welding gun height. This allows the mechanism to adapt to the processing needs of different sized parts and provides greater adaptability.

[0031] Working principle: When performing laser welding, first adjust the height of the welding gun 11 according to the specifications of the workpiece.

Loosen the limit screw 40 and adjust the position of the second connecting frame 23 to adjust the height of the welding gun 11. After positioning, tighten the limit nut 41. During welding, the movable center of the top of the welding gun 11 is fixed by the movable connection between the connecting frame 22 and the second connecting frame 23. Then, by controlling the movement of the turbine 27 on the screw 26, the position of one end of the sixth connecting frame 30 is changed, thereby changing the welding angle of the welding gun 11. The motor 37 drives the gear 34 to rotate, which in turn drives the entire angle adjustment mechanism to rotate through the second gear 39. During the rotation of the gear 34, the measuring instrument 35 measures the support... The rotation distance of shaft 36 allows operators to precisely control the rotation angle and distance via control panel 8, making it more adaptable to different processing needs. During use, welding gun 11 exerts a certain force on the metal surface, resulting in the splashing of high-temperature particles. By setting baffle 1, protective mirror 12, and deflector 3, the high-temperature particles splashed from multiple directions are blocked. Under the action of the tilt angle of deflector 3 and baffle 1, the high-temperature particles fall into the collection basket 10. At the same time, the suction fan 5 also collects smaller particles within the work area through ventilation pipe 16 and leakage hole 13. On the one hand, it provides protection for operators on a large scale, and on the other hand, it uses collection basket 10 to collect particles and then recycles these particles, which not only inhibits pollution caused by metal waste, but also reduces cost waste.
