Description

Technical Field

[0001] This utility model relates to a welding trolley, specifically a box foot welding trolley. Background Technology

[0002] Large container ships have numerous and uniformly styled legs, requiring frequent repositioning for manual welding, resulting in a large workload. However, manual welding is labor-intensive, operates in harsh environments, and suffers from inconsistent and unreliable quality. Furthermore, manual welding is inefficient. Therefore, a mobile welding vehicle is urgently needed. Utility Model Content

[0003] To address the issue of inconsistent quality in manual welding, this invention provides a box foot welding trolley.

[0004] This utility model provides the following technical solution:

[0005] A box-foot welding trolley includes a mobile trolley, a welding machine, a collaborative robot arm, a welding torch, and a 3D camera. The welding machine, the collaborative robot arm, and the welding torch are installed inside the mobile trolley. The collaborative robot arm is installed on the side of the welding machine. A welding torch holder is installed on the collaborative robot arm. A welding torch is installed on the welding torch holder. The welding wire inside the welding torch is guided by a wire feeder. A 3D camera is also installed on the collaborative robot arm near the welding torch.

[0006] Furthermore, light strips are installed on the outside of the mobile trolley; hanging brackets are installed on both sides of the mobile trolley.

[0007] Furthermore, a closed protective cover is installed on the upper part of the mobile trolley.

[0008] Furthermore, the lower part of the mobile trolley is equipped with front and rear omnidirectional wheels, with a steering motor installed at the front omnidirectional wheels and a rear wheel drive motor installed at the rear omnidirectional wheels.

[0009] Compared with the prior art, the beneficial effects of this utility model are: the trolley of this utility model can weld and move. The trolley is equipped with a welding machine, a collaborative robot arm and a welding torch. A 3D camera is also installed on the collaborative robot arm near the welding torch. The use of the collaborative robot arm greatly improves the working efficiency of the entire structure and significantly reduces costs. The 3D camera scans and accurately positions the weld seam of the component, with high measurement accuracy, meeting welding requirements. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-6 This utility model discloses a box foot welding trolley, including a mobile trolley 1, a welding machine 2, a collaborative robot arm 3, a welding torch 4, and a 3D camera 5. The welding machine 2, the collaborative robot arm 3, and the welding torch 4 are installed inside the mobile trolley 1. The collaborative robot arm 3 is installed on the side of the welding machine 2. A welding torch bracket 6 is installed on the collaborative robot arm 3. The welding torch 4 is installed on the welding torch bracket 6. The welding wire in the welding torch 4 is guided by a wire feeder 7. The 3D camera 5 is also installed on the collaborative robot arm 3 near the welding torch 4.

[0019] The mobile trolley 1 is equipped with light strips 8 for convenient lighting; the mobile trolley 1 is equipped with cable hangers 9 on both sides for convenient cable hanging.

[0020] The upper part of the mobile trolley 1 is equipped with a closed protective cover 10. The upper part adopts a closed design to avoid the erosion of rainwater.

[0021] The lower part of the mobile trolley 1 is equipped with front casters 11 and rear casters 12. A steering motor 13 is installed at the front caster 11 to improve the flexibility of steering and adjustment. A rear drive motor 14 is installed at the rear caster 12.

[0022] The use of a collaborative robotic arm greatly improves the overall efficiency of the structure, significantly reduces costs, and allows for multi-angle adjustment, increasing the freedom of welding.

[0023] The 3D camera uses MEMS coded grating structured light for scanning and reconstructs the true 3D point cloud data of the object based on a binocular image restoration algorithm, meeting the requirements of industrial-grade high-resolution, sub-millimeter measurement 3D vision applications. The device is small in size, has a large depth of field, high measurement accuracy, low cost, and is easy to operate.
