One person operates 4 robots, Han's collaborative robots help automate and flexibly ship welding

In the field of shipbuilding, welding is an extensive and crucial technology, and its quality directly affects the cycle, cost and quality of shipbuilding

In recent years, with the upward development of social economy, the younger generation has gradually "escaped" from high-intensity work (different welding point locations and types, operating postures of lying down, squatting, or lying down for a long time) and poor working environment (sultry, hot, The age structure of skilled welders in ship welding workshops where welding spatters and generally require wearing heavy protective clothing is abnormal, and the average age is significantly older. In addition, the high-end transformation of the domestic shipbuilding industry is accelerating, and companies have naturally higher and higher requirements for welding processes related to ship quality.

client needs

The customer is a "smart factory solution pilot demonstration" enterprise in the domestic shipping industry. It has built and delivered more than 270 high-quality ships to global users, including bulk carriers, car carriers, ultra-large container ships, oil tankers, and ore carriers. Special ships, dual-fuel ships, etc. have the reputation of "super cargo king at sea" in the industry.

The volume of shipbuilding welding depends on the ship type. Among the ship orders contracted by customers, medium and thick plates account for a relatively large proportion. In order to ensure quality, "each weld requires dozens of welding processes, and the pass rate during film inspection is required to reach 100%." Under such strict quality requirements, the efficiency of traditional manual welding cannot meet expectations. Customers hope to use more automated, flexible, and intelligent welding robots to achieve stable and reliable welding quality while improving welding efficiency and ensuring timely delivery. .

Hanzu Robot Solution:

Adopting the Elfin series collaborative robot body, it is light in weight and can be carried/carried to any location in the welding workshop by a single person; it is simple to operate, and can be quickly put into welding operations through drag-and-drop teaching or graphical programming; repeatable positioning accuracy Up to ±0.02mm, meeting welding accuracy requirements.

During actual welding operations, the welder master can easily complete welding task establishment, welding starting point, welding end point, welding start and other operations through the drag and drop process through the button at the end of the robotic arm, which is simple, convenient and efficient.

Compared with other collaborative robots, Han's Robot series products also have the following advantages, making them more suitable for welding applications:

The content that needs to be rewritten is: first, a robotic arm structure that is more suitable for welding. Han's robot adopts a unique double-joint module design. One motion module contains two joints, forming a unique kinematic structure, which can achieve higher flexibility during welding operations. The Elfin-Pro series of collaborative robots adopt internal circuit layout, and all welding operations can effectively avoid problems such as limited range of movement of the robotic arm and interference with communication signals due to entanglement of external wire harnesses

Second, more convenient and efficient teaching operation. Elfin-Pro supports integrated end force control, which can be easily dragged with only a drag force within 3N; it helps users drag the welding gun to the designated target solder point easily and quickly, achieving accuracy and improving work efficiency.

Third, it is more open and adaptable to all types of welding equipment. Han's robots can quickly adapt to domestic and foreign mainstream welding machines, including Megmeet, Rochi, Aotai, Binzer, Panasonic, Funis and Idaxin, etc., and can also cooperate with robot vision and control focusing on the welding industry. Efficient docking with device manufacturers to expand customers’ product selection space.

Adhering to the mission of “serving the people with robotic technology”, Han’s Robots continues to polish and optimize the welding process package to make welding operations simpler and more efficient. At the same time, Han's robots also have advantages in the field of welding such as "arc tracking", "laser visual seam tracking" and "multi-layer multi-pass welding".

effect evaluation:

Quality and efficiency are improved, saving manpower: According to the relevant person in charge of the customer's factory department, when all equipment is running normally, an ordinary welder can operate 4 welding robots at the same time, and the operating efficiency is greatly improved, and the welding quality is higher. Compared with traditional manual welding, it is more stable and reliable, and the consistency of the finished product is also stronger.

It is conducive to further improving the intelligence level of the welding workshop: strengthening the application of welding robots in the field of shipbuilding is an industry development trend. With the help of Han's Robots, the proportion of welding robots in customers' segmented production workshops has gradually increased, and the level of welding automation and intelligence has steadily improved, allowing customers to maintain a leading position in the increasingly competitive shipbuilding field.

Welding robots are closely integrated with ship construction and can significantly improve the production efficiency and automation level of shipbuilding and ship repair enterprises. Han's Robot will continue to explore the unique advantages of collaborative robots in ship welding and other fields, and provide users and partners with robotic arm products that are more suitable for welding
