[0002] Welding robot is a kind of industrial robot. It is a multi-joint manipulator or multi-degree-of-freedom machine device widely used in the industrial field. It has a certain degree of automation and can rely on its own power energy and control capabilities to achieve various industrial processing and manufacturing functions. It is widely used in various industrial fields such as electronics, logistics, and chemical industry.

[0003] When welding, the welding robot faces different environments and metals, and usually needs to install auxiliary accessories according to the use environment and design. For example, in an indoor environment with poor ventilation, it is necessary to install smoke absorption accessories on it to reduce the smoke caused by welding.

[0004] The smoke auxiliary adsorption accessories on the existing welding robots are usually used as a simple auxiliary accessory, which can only simply adsorb the smoke caused by the welding robot. However, due to the complexity of the working environment of the welding robot, the dispersion of the smoke generated during welding is uncontrollable. The existing smoke adsorption accessories have a relatively single working angle, and the adsorption effect and adsorption angle are both poor, and the use effect is not good. Therefore, in view of the above problems, a welding smoke adsorption device for a welding robot is proposed. Utility Model Content

During operation, after the mounting plate 25 is fitted with the external mechanical arm, the external connecting bolts are used to fix the mechanical arm through the mounting screw holes 26, thereby improving the stability of the connection between the device and the external mechanical arm.

[0033] Working principle: When the range of smoke generated by robot welding is large, by rotating the adjusting bolt 9, the adjusting bolt 9 drives the connecting column 11 thereon to rotate, and then when the connecting column 11 moves through the adjusting bolt 9, the adjusting seat 7 is driven by the rotating column 13 to rotate with the fixed column 8 as the center of the circle, and then the adjusting seat 7 drives the second smoke adsorption cylinder 3 and the second adsorption fan 4 to be adjusted to a suitable angle, so that when in use, the adsorption angle of the second adsorption fan 4 can be adjusted according to the drifting angle of the smoke caused by the robot welding, thereby improving the applicability of the overall use of the device, improving the adsorption effect of the smoke, reducing the harm of the device to the environment and surrounding workers, and improving the use of the device. When the adjustment seat 7 rotates with the fixed column 8 as the center, it drives the second smoke adsorption cylinder 3 and the second adsorption fan 4 connected thereto to adjust the adsorption angle through the connection of the connecting block 14, thereby improving the stability of the device when adjusting the angle of the second smoke adsorption cylinder 3 and the second adsorption fan 4.

The design of the transmission motor 15 facilitates the quick adjustment of the adsorption angle of the second smoke adsorption cylinder 3 and the second adsorption fan 4. The speed can be adjusted to improve the use effect of the device. When the external smoke is extracted by the first adsorption fan 2 and the second adsorption fan 4, the harmful substances in the smoke can be adsorbed. Through the design of the first smoke adsorption cylinder 1 and the first conical tube 18, the larger first adsorption fan 2 can improve its adsorption effect. The conical first conical tube 18 can reduce its small volume after the harmful substances in the smoke are adsorbed, so that it is convenient to install it on the external welding robot arm, thereby improving the applicability of the device. The harmful smoke adsorbed by the second adsorption fan 4 is adsorbed and introduced into the first smoke adsorption cylinder 1 through the second conical tube 20, the connecting hose 21 and the telescopic elastic hose 22. The filter element 17 in the first smoke adsorption cylinder 1 is used to adsorb and filter it, thereby improving the adsorption effect of the device on harmful substances in the smoke, and through the design of the spring in the telescopic elastic hose 22, the telescopic elastic hose 22 can be retracted, thereby facilitating the adjustment of the adsorption angle of the second smoke adsorption cylinder 3, and by connecting the mounting plate 25 with the external welding robot arm, and through the structure of the second annular frame 23 and the mounting plate 25, the stability of the device during installation and connection can be improved. After the mounting plate 25 is fitted with the external robot arm, it is fixed to the robot arm through the external connecting bolts through the mounting screw holes 26, thereby improving the stability of the connection between the device and the external robot arm.
