[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] like Figure 1 The illustrated device is a welding robot for steel support components, such as... Figure 2 The diagram shows a welding module and a full welding module; the device includes: a side-by-side workbench module 1, each including a frame-type support frame 11 and an end support column 12; a spot welding processing module 2, used to fix the structural plate of the steel support component for spot welding to form a spot welded steel support component, including a mounting plate 20, a first processing fixture 21 and a first positioning structure; a full welding processing module 3, used to place the spot welded steel support component for full welding, including a mounting plate 20, a second processing fixture 31 and a second positioning structure; the spot welding processing module and the full welding processing module are fixedly mounted on the frame-type support frame; a welding robot 4 is arranged between the side-by-side workbench modules.

[0028] In the engineering field, column-shaped building materials are often used to improve transportation efficiency and meet practical needs. The production and transportation of column-shaped building materials are usually done as individual columns. However, when used on-site, individual column structures may encounter instability issues. In such cases, additional support structures are usually installed at the bottom of the column-shaped building material to increase the contact area and support the stability of the column-shaped building material.

[0029] The supporting structure is generally made of steel and has a rather special shape. If manual welding is used, the efficiency will be low.

[0030] The use of robots / robotic arms for welding to replace manual labor is a technological development trend, but the key is to make full use of the advantages of robots.

[0031] Specifically, a workbench module is set up side by side. The workbench module includes a frame-type support frame and end support columns. The advantages of the frame-type support frame are that it has a simpler structure, is lighter, and has lower cost. Moreover, since various parameters may be changed during processing, the frame-type support frame is easier to control and has better safety. The two end support columns are respectively connected to the two ends of the frame-type support frame to keep the frame-type support frame in a horizontal position.

[0032] Steel support components need to be fabricated from scratch, requiring the structural plates to be welded together. Theoretically, full welding is possible, but this presents several practical problems: First, occasional welding anomalies can occur, rendering the entire steel support component unusable and costly if full welding is used directly. Second, alternating operations are difficult, failing to fully utilize the advantages of side-by-side workbench modules. The spot welding module uses a mounting plate as a foundation to support the first processing fixture and the first positioning structure. The first processing fixture controls the placement of the structural plates (welding and placement positions), while the first positioning structure serves as a mistake-proofing mechanism and provides a low-cost method for position control. The full welding module follows the same structure.

[0033] When the welding robot is positioned between the side-by-side workbench modules, its working sequence proceeds from position 1 to position 4. During the transition between work positions (spot welding and full welding modules each represent a workbench), three workbenches are in a ready-to-process state. At this time, tasks such as material preparation, effect inspection, and material movement can be performed. This alternating work mechanism achieves a balance between processing efficiency, cost control, and quality control, comprehensively improving the efficiency of the entire welding operation.

[0034] The end support column is equipped with a rotating shaft that can move up and down. The rotating shaft is connected to a mounting plate, and the mounting plate is provided with mounting holes at different positions and / or of different specifications. The mounting plate is connected to the side of the frame support frame through the mounting holes. A transmission structure is provided inside the end support column, and the transmission structure is connected to the rotating shaft. A lifting structure is also provided inside the end support column, and the transmission structure is located in the lifting structure. The end support column is equipped with a control console for controlling the transmission structure and the lifting structure.

[0035] When the steel support components are of different models, their structures are different. Although robots can flexibly encode programs to adapt to the differences in specific structures, the specifications of the spot welding and full welding processing modules will also change accordingly. In this case, if the external auxiliary equipment (such as manual inspection and auxiliary equipment operation) also needs to be modified at the same time, the cost will be high. By adjusting the rotating shaft (rotation angle and vertical position), it is possible to adapt to this change as much as possible. Although it is impossible to completely match the processing requirements of different steel support components, by making the processing conditions as consistent as possible, the occurrence of accidents can be reduced, efficiency can be improved and costs reduced.

[0036] The rotating shaft is not directly connected to the frame support because, firstly, their compatibility is poor, and secondly, isolation reduces the probability of damage caused by conflict. The mounting plate has a connection structure matching the rotating shaft on one side, and mounting holes of different positions and / or sizes on the other side, allowing for the installation of different frame support frames in various locations. The transmission structure can include an electric motor or a simple gear structure, enabling the rotating shaft to rotate at a certain angle; the specific design is not limited. The rotating shaft and transmission structure can be housed in an empty box (space), with a lifting structure underneath. The lifting structure can be a cylinder lift or a chain lift; the specific design is not limited. The control console has a matching control structure based on the specific transmission and lifting structures.
