As a moving part, the raw material of the robot arm determines the static dynamic functions of the robot arm. Most of the traditional manipulators use light alloys such as aluminum alloys alloy steels as raw materials. However, the carbon fiber manipulators are occupied by carbon fiber manipulators in terms of specific gravity, creep, strength, cost. Quite a number of advantages.
The self-weight of the robotic arm will affect its own speed of movement the power consumption of the movement. At the same time, it needs to have good controllability accuracy of operation. After all, the robotic arm must only bear its own weight, but also bear the weight of grasping the workpiece. The manufacturing material of traditional manipulators-the density of aluminum is 2.7g/cm3, the density of steel is 7.8g/cm3, the carbon fiber is only 1.7g/cm3. Boshi has developed a carbon fiber manipulator for an enterprise , the overall manipulator The total weight is only 3kg, the overall weight is more than 50% less than that of the traditional material manipulator.
Secondly, when the mechanical arm is under load, it must have fracture strain, which means that the material used to make the mechanical arm must have sufficient strength, "high-strength materials" must be selected. Traditional metal materials will cause bending deformation of the arm in the vertical plane torsional deformation of the inner side of the horizontal plane due to insufficient rigidity, the arm will vibrate accordingly, even cause the workpiece to be stuck. The tensile strength of carbon fiber composite materials is about 1400MPa, which is several times that of steel. It has advantages over traditional metal materials in terms of elastic modulus load capacity, has the ability to adapt to high-strength operating frequencies.
Carbon fiber manipulator:
In addition, an economic perspective, it seems that carbon fiber raw materials are much more expensive than aluminum alloys, but in specific applications, raw materials to molding, the processing cost accounts for a greater proportion of the cost. However, after the efforts of many materials people, the price gap between the carbon fiber robot arm the traditional aluminum alloy robot arm has been narrowed. The technicians of Jiangsu Bosh Carbon Fiber have also optimized upgraded the carbon fiber manipulator products. At present, the price difference between the two can be reduced to almost the same.
