Carbon fiber robot arm

At present, the robot arm is the most widely used mechanical automation device in the field of robotics, which is used in many fields such as electronics, medical treatment, machining and manufacturing. The basic function of the manipulator is to guide the gripper to accurately grasp the workpiece to the required position and bear the weight of the arm and the maximum weight of the workpiece.

At present, the robot arm is the most widely used mechanical automation device in the field of robotics, which is used in many fields such as electronics, medical treatment, machining and manufacturing. The basic function of the manipulator is to guide the gripper to accurately grasp the workpiece to the required position and bear the weight of the arm and the maximum weight of the workpiece. Although the shape of the manipulator is different, they all have the same point, that is, they can accept the command and precisely locate to a certain point for operation. As a moving part, the choice of material will determine the static and dynamic performance of the manipulator. At present, carbon fiber material is used to replace the traditional metal in the robot manipulator.


Traditional mechanical arms are mostly made of metal materials, such as aluminum alloy and steel. In addition, some automatic detection devices, pipelines, cooling devices, etc. will also be installed on the mechanical arm. Because the mechanical arm is a typical cantilever structure, its own quality will have a great impact on the mechanical arm itself, so if you want to meet the static and dynamic performance, but also reduce the quality of the mechanical arm, you can choose the appropriate structure and the light density Materials to achieve the lightweight of the manipulator.


The manipulator should not only bear its own weight, but also bear the maximum weight of the workpiece, which requires that the manipulator should not have strain and fracture when bearing the load. From the aspect of tensile strength, the tensile strength of carbon fiber composite is 2000 MPa, and that of aluminum alloy is about 800 MPa; in the aspect of toughness, the toughness of aluminum alloy is relatively low and lacks elasticity. Because carbon fiber has the soft processability of textile fiber, its toughness is far higher than that of aluminum alloy, and carbon fiber material is also less likely to fracture.


In the domestic industrial robot manufacturing, the application trend of carbon fiber in the manipulator is more and more obvious. In addition to some large-scale carbon fiber manipulator in the aviation field, some small and medium-sized mechanical arms in life also begin to appear carbon fiber materials.
