With the development of science and technology, more and more industrial robots are used in industrial production. As one of the important structures of industrial robots, the robotic arm is a more important processing component in modern industrial production. With the continuous expansion of the carbon fiber composite material application industry, more and more industrial robots begin to use carbon fiber robot arms, so what are the advantages of carbon fiber robot arms?
The well-known advantages of carbon fiber materials are light weight and high strength, because these advantages make it highly respected in aerospace, military and other aspects. With the development of technology and the continuous improvement of carbon fiber production technology, carbon fiber materials have become more and more popular in civilian use. In production and daily life, we can see that many and many products are made of carbon fiber composite materials.
Industrial robot
The carbon fiber robot arm made of metal not only feels clumsy and inflexible during operation, but also has poor fatigue resistance. Since the robot arm is a typical cantilever beam structure, its own quality will have a great impact on the robot arm itself Therefore, if you want to achieve both static and dynamic performance while reducing the mass of the robotic arm, you can achieve lightweighting of the robotic arm by choosing a suitable structure and choosing a light-density material.
Taking aluminum alloy as an example, the specific gravity of aluminum alloy is 2.7g / cm3, carbon fiber is lighter than aluminum alloy, and its specific gravity is 1.5-2.0g / cm3. Carbon fiber manipulator is also the lightest of all mechanical arms of different materials. In addition, the carbon fiber deforms very little at room temperature. According to the test data provided by Boshi Carbon Fiber, the aluminum alloy robot arm parts with the same length of 100cm and the carbon fiber robot arm parts are placed at room temperature 12 ° C for the same time. The final aluminum alloy robot arm parts change by 0.13mm, but the carbon fiber robot arm has zero The components are not deformed at all, which is conducive to maintaining precision and accuracy of the robotic arm.
Carbon fiber manipulator
The robot arm must not only bear its own weight, but also bear the maximum weight of the gripping workpiece. This requires that the robot arm must not be strained or broken when it is under load. From the perspective of tensile strength, the tensile strength of carbon fiber composite materials is 2000MPa, and the tensile strength of aluminum alloy is about 800MPa; in terms of toughness, the toughness of aluminum alloy is relatively low and lacks elasticity. Carbon fiber can be processed due to the softness of textile fibers The toughness is much higher than that of aluminum alloy, and the carbon fiber material is also less prone to fracture. And the carbon fiber robot arm will not produce rust and surface wear during long-term operation, and requires less daily maintenance.
Carbon fiber robot arm
Many manufacturers still apply carbon fiber manipulators in terms of cost, but Bosch Carbon Fiber once made a comparison between the cost of carbon fiber manipulators and aluminum alloy manipulators. The production cost of carbon fiber manipulators is higher than that of aluminum alloy manipulators. portion. However, with the continuous progress and maturity of domestic carbon fiber technology, in fact, the cost of the two material robot arms is almost the same, and the service life of the carbon fiber material is longer than that of the metal, and the maintenance is relatively simple. The material characteristics and cost performance have great advantages, and the future development prospects are also very broad.
In the manufacture of domestic robots, the application of carbon fiber is becoming more and more extensive, and some small and medium-sized 6-axis robots in life have also begun to use carbon fiber manipulators. JSBS carbon fiber has developed carbon fiber manipulators for many research institutes and enterprises, which are used in electronics and manufacturing.
