Application of carbon fiber to the lightweight of robotic arms

Since the founding of the People's Republic of our country, our country has lived a peaceful life for decades. During this period, my country's comprehensive strength has been continuously rising. With the rapid development of domestic electronic information technology, due to the continuous improvement of the degree of industrialization in my country, industrial robots have gradually attracted the attention of manufacturing manufacturers. And the demand for industrial robots is also increasing. In response to the increasing demand for domestic industrial robots, industrial robot manufacturers are working hard to improve the quality of their products. The lightweight robot can effectively improve the dynamic performance and operational performance of the robot, and the lightweight structural parts can greatly reduce the consumption of electric energy, which is in line with the current concept of "energy saving, low-carbon life". 3G Carbon, a carbon fiber composite material manufacturer, takes you to understand the application of carbon fiber composite materials to robots.

Lightweight has been advocated in many fields. For industrial robots, light weighting is a huge and complex project, and issues such as design, material selection, and technology need to be considered. The mechanical arm is an important part of the robot, so the performance of the mechanical arm directly affects the operation of the robot. Why choose carbon fiber for the robot parts? There are 3 main reasons:

(1) Carbon fiber composite materials are currently the most cost-effective lightweight materials. As the force-bearing parts of the robot, the weight of the robotic arm needs to be as light as possible, so that it can carry heavier items. The manipulator made of carbon fiber composite material can reduce the weight by 60% compared with the manipulator made of lightweight aluminum, which will make the manipulator more sensitive and consume less electricity during the work.

(2) Carbon fiber composite materials also have obvious advantages in strength. Friends who have paid attention to fiber composite materials know that carbon fiber has the title of the king of materials. It can't be held back either. The robotic arm not only needs to bear the weight of the grabbed items but also its own quality during the work. According to the experimental data, the specific strength and specific modulus of carbon fiber materials are higher than those of steel, which can reach 7-9 times that of steel, and the tensile strength can reach 3500MPa. In order to better explore the tunnel, a company uses a carbon fiber manipulator. The thickness of this manipulator is only 5cm and the diameter dimension is 18cm, but it can bear a weight of more than 100 kilograms.

(3) Carbon fiber material products have low creep and high precision. Everyone has heard the phenomenon of thermal expansion and contraction. This is an objective existence. No matter what material it is, there will be thermal expansion and contraction. The only difference is thermal expansion and cooling. shrinkage issue. Carbon fiber composite materials have a very low coefficient of thermal expansion and contraction, which can maintain the original size and performance even in harsh environments, and can complete tasks in extreme climates.
