At present, robotic arms are widely used in industrial manufacturing, medical treatment, entertainment services, military, semiconductor manufacturing, and space exploration. Traditional robotic arms are mostly made of metal materials, such as aluminum alloys and steel. In addition, some automatic detection devices, pipelines, cooling devices, etc. will also be installed on the manipulator. Since the manipulator is a typical cantilever beam structure, its own quality will seriously affect the positioning accuracy and operation efficiency of the metal manipulator.
Carbon fiber is a high-strength, light-weight high-performance fiber，there are various types of carbon tubes, such as cnc tubes . Carbon fiber specific gravity is lighter than aluminum, less than 1/4 of steel, and its specific strength is 20 times that of iron. The tensile strength is more than 7-9 times that of steel, acid and alkali corrosion resistance, and it is not easy to deform, and can adapt to harsh environments for a long time. Robotic arms made of carbon fiber composite materials can make up for the defects of metal arms.
For industrial robots, improving the load-to-weight ratio is the main task for new materials. Bearing capacity, self-weight, rigidity, motion inertia, position accuracy, etc. are several important indicators for the selection of materials for industrial robots. These requirements seem to be contradictory, because good rigidity and heavy load often mean that the structure is thick, There are many guide rods, which will inevitably increase the weight of the arm.
The robotic arm not only has to bear its own weight, but also needs to bear the maximum weight of the workpiece, which requires that the robotic arm cannot be strained and broken when it is under load. In terms of tensile strength, the robot arm is made of carbon fiber composite tubes, the tensile strength of carbon fiber composites is 2000MPa, and the tensile strength of aluminum alloys is about 800MPa; in terms of toughness, aluminum alloys are relatively low in toughness and lack elasticity. Carbon fibers can be processed due to the softness of textile fibers. Therefore, the toughness is much higher than that of aluminum alloy, and the carbon fiber material is less prone to fracture.
The movement speed of the manipulator from starting to braking has a direct impact on the stability of its work. The lighter the self-weight of the arm, the smaller the inertia of the movement, the smoother and smoother the operation, and the higher the final position accuracy. Taking a carbon fiber robotic arm as an example, the total length is 1500mm, the width is 150mm, and the wall thickness is 5mm. The total weight of the entire robotic arm is only 5kg. This lightweight effect significantly improves the operation accuracy of industrial robots.
With the continuous development of carbon fiber production and manufacturing technology, the application of carbon fiber on robotic arms is becoming more and more popular in domestic industrial robot manufacturing. In addition to some large carbon fiber robotic arms in the aviation field, carbon fiber materials have also begun to appear on some small and medium-sized robotic arms in life.Large carbon fiber robotic arms are available with our large carbon fiber tubing material.If you need carbon fiber tube, please contact our carbon fiber tube manufacturer.
