[0027] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0028] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present utility model. The phrase "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or alternative embodiment that is mutually exclusive with other embodiments. The present utility model provides the following embodiments.

[0029] As shown by Figure 1 , Figure 2 and Figure 3 a welding robot for a steel structure includes a main body 1, a steering force arm 2, a welding end 3, and a connecting pipeline 4. The steering force arm 2 is rotatably installed at the top end of the main body 1, the welding end 3 is rotatably installed at the end of the steering force arm 2, and the connecting pipeline 4 is arranged on the side of the steering force arm 2. A purification mechanism 5 is fixedly installed on the side of the steering force arm 2. The purification mechanism 5 includes a lower fixing frame 51, an upper fixing frame 52, a fixing end 53, a purification filter element 54, and a mating pipe 55. The lower fixing frames 51 are symmetrically and fixedly installed on the side of the steering force arm 2. The upper fixing frame 52 is rotatably installed at the top end of the lower fixing frame 51. The fixing end 53 is arranged on the common side of the lower fixing frame 51 and the upper fixing frame 52. The purification filter element 54 is arranged inside the lower fixing frame 51 and the upper fixing frame 52. The mating pipes 55 are symmetrically and fixedly installed on both sides of the purification filter element 54. A collection mechanism 6 is fixedly installed at the end of the connecting pipeline 4. An absorption mechanism 7 is arranged on the side of the steering force arm 2.

[0030] During use, the device is installed at the target position, and then through the cooperation of the main body machine 1 and the steering force arm 2, the angle of the welding end 3 itself is changed and adjusted, so that the welding end 3 can perform multi-angle welding on the bottom components. During the welding process, through the use of the suction mechanism 7, the smoke generated during the welding of the welding end 3 is sucked, and then through the cooperation of the collection mechanism 6, the smoke is transported into the purification mechanism 5. After that, through the use of the purification mechanism 5, the sucked gas is purified, reducing the harmful components in the welding smoke. Through the use of the cooperation pipe 55, the sucked gas is transported into the purification filter element 54. Through the use of the purification filter element 54, the harmful components in the gas are filtered, reducing the harmful part of the gas, and then discharged through another group of cooperation pipes 55 to complete the purification of the gas. And during subsequent use, through the cooperation of the fixed end 53 and the upper fixing frame 52, the space inside the upper fixing frame 52 and the lower fixing frame 51 can be quickly opened, facilitating the replacement of the purification filter element 54, making the use of the device itself more efficient and stable, thereby improving the working quality of the device itself.

[0031] As shown by the attached Figure 4 In this embodiment, as shown, the steering force arm 2 is composed of a combination of multiple mechanically connected arms. During use, it can change and adjust the welding end 3 in multiple angles and directions, enabling the welding end 3 to better perform welding operations on the bottom structure.

[0032] As shown by the attached Figure 4 In this embodiment, as shown, the side of the purification mechanism 5 is fixedly connected to the connecting pipeline 4. During use, through the connection of the cooperation pipe 55 and the connecting pipeline 4, it is convenient for the gas collected inside the connecting pipeline 4 to be input into the purification filter element 54, and it is also convenient for the overall disassembly and maintenance of the subsequent purification mechanism 5.

[0033] As shown by the attached Figure 5 In this embodiment, as shown, the collection mechanism 6 includes a collection plate 61, a mounting block 62, side plates 63, reinforcing screws 64, and a connecting block 65. The side plates 63 are symmetrically and fixedly installed on the side of the steering force arm 2. The mounting block 62 is slidably installed inside the side plates 63. The mounting block 62 and the inside of the side plates 63 are jointly threadedly installed with the reinforcing screws 64. The collection plate 61 is fixedly installed on the side of the mounting block 62. The connecting block 65 is fixedly installed at the bottom of the collection plate 61. The connecting block 65 is fixedly connected to the connecting pipeline 4.

[0034] During use, through the cooperation of the mounting block 62 and the side plate 63, the installation and positioning of the collection plate 61 are quickly completed. Then, through the use and cooperation of the collection plate 61 and the connecting block 65, the smoke generated during the welding operation of the welding end 3 is sucked, and then conveyed to the interior of the subsequent components. Moreover, by utilizing the mechanism and shape of the collection plate 61 itself, the sparks generated during welding can be blocked to prevent the sparks from splashing onto the pipelines on the side and causing burns to the overall pipelines.

[0035] As shown in the attached Figure 5 In this embodiment, a sieve partition net is fixedly installed inside the collection plate 61. During use, through the installation of the sieve partition net, certain sparks and metal debris generated during welding can be blocked and filtered to prevent the sparks and debris from entering the connecting pipeline 4 and scratching the inner wall of the connecting pipeline 4.

[0036] As shown in the attached Figure 6 In this embodiment, a baffle is fixedly installed on the side of the collection plate 61. During use, the shielding range of the collection plate 61 itself is expanded, and the sparks generated during welding can be comprehensively protected and blocked.

[0037] As shown in the attached Figure 6 In this embodiment, the suction mechanism 7 includes a housing 71, a main pump 72, an input pipe 73, and an output pipe 74. The housing 71 is fixedly installed on the side of the steering force arm 2, the main pump 72 is fixedly installed inside the housing 71, the input pipe 73 is fixedly installed at the air inlet of the main pump 72, and the output pipe 74 is fixedly installed at the air outlet of the main pump 72.

[0038] During use, first connect the input pipe 73 to the purification mechanism 5, the connecting pipeline 4, and the collection mechanism 6 to ensure the smoothness of the pipeline connection. Then, through the operation of the main pump 72, according to the change in the internal pressure of the main pump 72, the input pipe 73 sucks the smoke and gas on the side of the collection mechanism 6 through the pipeline. During the suction process, multiple processes are gradually passed through to quickly complete the filtration process. Then, through the use of the output pipe 74, the filtered gas is directly discharged.

[0039] As shown in the attached Figure 1 In this embodiment, the connecting pipeline 4 is a telescopic flexible connecting pipeline. During use, by limiting the structure and material of the connecting pipeline 4 itself, it is convenient for the connecting pipeline 4 to stretch and twist following the bending of the robotic arm of the steering force arm 2, ensuring the stability of the pipeline connection.

[0040] The above content further elaborates on the present utility model in combination with specific embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model pertains, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, and all should be regarded as belonging to the protection scope determined by the claims submitted for the present utility model.
