[0022] In order to make the purpose, technical scheme and advantages of the present application more clear and explicit, the following will be combined with specific embodiments and refer to the accompanying drawings Figs. 1-2 , the present application will be further described. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present application. In addition, in the following description, the description of known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present application.

[0023] The utility model provides a kind of steel pipe tower component assembling and welding workstation of intelligent cooperation, including steel pipe adjusting unit, the one side of steel pipe adjusting unit is equipped with welding unit, the other side of steel pipe adjusting unit is equipped with spare part grabbing unit.

[0024] The main function of steel pipe adjusting unit is to accurately adjust the position and angle of steel pipe, to ensure the stability and accuracy of steel pipe during assembling and welding. The unit includes a C-shaped positioner 20 and support roller racks on both sides of the C-shaped positioner 20. The C-shaped positioner 20 can flexibly adjust the angle of the steel pipe to adapt to different welding needs, thereby improving the welding quality and efficiency.

[0025] The support roller racks are slidingly installed on the roller rack sliding rails 16, and are equipped with lifting assemblies 13 on the top. The top of the lifting assembly 13 is equipped with a steel pipe support component.

[0026] The support roller racks are equipped with traveling wheels and roller rack driving devices that drive the traveling wheels to move on the roller rack sliding rails 16, enabling the support roller racks to move flexibly along the sliding rails, thereby enabling the steel pipe to move axially.

[0027] The lifting assembly 13 can be a lifting cylinder component or a lifting lead screw component. The lifting cylinder component has the characteristics of fast response speed and simple operation, and is suitable for occasions with high requirements for lifting speed. The lifting lead screw component has the advantages of high precision and good stability, and is suitable for occasions with high requirements for the position accuracy of the steel pipe. This diversified implementation mode can be selected according to different production needs, further enhancing the adaptability of the equipment.

[0028] The steel pipe support component includes a support frame 12 and two support wheels 11 rotatably arranged on the support frame 12. The axial directions of the two support wheels 11 are the same as the axial direction of the workpiece. Not only can the steel pipe 21 be stably supported, but also can be allowed to rotate when needed, providing a better welding angle for the welding robot and further improving the welding efficiency and quality.

[0029] When it is necessary to move the steel pipe 21 axially for welding and discharging, the two support roller racks are at the lower end of the steel pipe, the lifting assembly brings the support wheels 11 into contact with the outer wall of the pipe, the C-shaped positioner 20 releases the steel pipe 21, at this time the lifting assembly 13 is raised again, so that the steel pipe is higher than the clamping opening of the C-shaped positioner 20, and the two support wheel racks move in the same direction at the same time, thereby realizing the axial movement of the steel pipe. The rear lifting assembly 13 lowers the steel pipe to the clamping opening of the C-shaped positioner. When it is necessary to adjust the angle and rotate axially, the C-shaped positioner 20 clamps and drives the steel pipe to rotate. At this time, the two sides of the steel pipe are arranged on the support roller racks to prevent tilting during clamping and rotating.

[0030] The welding unit is located on one side of the steel pipe adjusting unit, and its main function is to realize efficient welding of the steel pipe tower parts. The unit includes a welding gantry 5, and two welding robots are slidingly arranged on the welding gantry 5. Each welding robot has an independent driving system and can be operated separately to meet the simultaneous welding on both sides. The welding robot includes a welding arm 3, a welding wire supply part 2, and a welding wire barrel 4 connected with the welding wire supply part 2. Through the cooperative work of the two welding robots, the two ends of the steel pipe tower part can be welded at the same time, greatly improving the welding efficiency.

[0031] The welding arm 3 of the welding robot has high-precision motion control capability and can accurately reach the welding position to ensure the stability of the welding quality. The design of the welding wire supply part 2 and the welding wire barrel 4 ensures the continuity of the welding process and reduces the downtime caused by welding wire replacement.

[0032] The component grabbing unit is located on the other side of the steel pipe adjusting unit, and its main function is to efficiently grab and place components on the outer wall of the steel pipe to support the assembly and welding work. The unit includes a material taking robot 22 slidingly arranged along the workpiece axis, and a component placement platform 18 is arranged on the side of the material taking robot 22. The material taking robot 22 can automatically grab components according to the preset program and accurately place them at the welding position, reducing manual intervention and improving production efficiency. The component placement platform 18 includes a plurality of positioning pins arranged along the periphery of the component and corresponding holes, which can ensure the accurate position of the component when placed, providing good welding conditions for the welding robot and further improving the welding quality.

[0033] The material taking end of the material taking robot 22 is provided with a component recognition camera, so that the material taking robot 22 can automatically identify the type, position and attitude of the component, thereby realizing accurate grabbing. This not only reduces manual intervention and improves production efficiency, but also effectively avoids production accidents caused by incorrect grabbing, further improving the reliability and safety of production.

[0034] During operation, first, the workstations are initialized and production parameters are input by the control system, and the material taking robot of the component grabbing unit accurately grabs the components using the component recognition camera and places them on the steel pipe; then, the C-shaped displacement machine, lifting assembly and roller frame driving device of the steel pipe adjusting unit work cooperatively to adjust the steel pipe to a position and angle suitable for welding; and the welding robot of the welding unit performs welding operation according to the preset parameters and path.

[0035] The taking robot places the parts at the corresponding positions of the steel pipe tower according to preset parameters, waits for the welding robot to perform spot welding, at this time, the parts have been temporarily connected with the steel pipe tower, the feeding robot moves to the steel pipe tower on the other side of the C-shaped positioner to take the parts, at this time, the welding robot on one side performs full welding on the basis of spot welding, the taking robot grasps the parts to the predetermined position of the steel pipe tower, the welding robot on the other side performs spot welding, the taking robot on the other side is loosened and moves to one side, the welding robot on the other side performs full welding, at this time, the welding robot on one side also completes welding, and then performs spot welding, so that simultaneous welding is realized on both sides of the steel pipe tower under the action of one taking robot and two welding robots, and the work efficiency is improved
