Why are carbon fibre composite robotic arms getting more more attention the public?

    Robotic arms are important production processing components in current industrial production. Of course, this is the convenience of production brought by current technology. The robots we can see are industrial robots . Robotic arms are one of the important structures of industrial robots. With the development of carbon fiber materials, it has gradually become a processing robot arm that can replace other materials.

Robotic arms are the most widely used automated mechanical devices in the field of robotics . Although their shapes are different, they all have one common feature, that is, they can receive instructions locate a certain point in three-dimensional ( two-dimensional) space to perform operations.

Robot arms generally have three types of movements: extension, rotation, lifting. The rotation lifting movements are completed by the cross arm the column. The basic function of the arm is to move the gripper to the desired position bear the weight of the grasped workpiece the weight of the arm itself.

In addition, pipelines, cooling devices, travel positioning devices automatic detection devices are generally installed on the arm. Therefore, the structure, working range, load-bearing capacity movement accuracy of the arm will directly affect the working performance of the entire machine. Alloy steel, heat-treated high-quality steel, aluminum alloy other light alloys are all raw materials for making robotic arms, but according to the market, robotic arms made of carbon fiber composite materials will become a major trend in the production of robotic arms in the next few years.

Take a carbon fiber robotic arm developed customized by Shenzhen Huiwen Intelligent Co., Ltd. as an example. The robotic arm is 930mm long, 150mm wide, 5mm thick, weighs only 3.5kg. It is reported that although the carbon fiber robotic arm has certain difficulties in the molding process, the comprehensive comparison of multiple factors such as specific gravity, strength, creep resistance cost price, the carbon fiber robotic arm is replacing the traditional metal robotic arm.

As a moving component, the robotic arm generally has to complete various predetermined future movements. The choice of material determines the dynamic static performance of the robotic arm.

Lightweight materials are a good choice for making robotic arms. Because the weight of the robotic arm only affects its convenience of movement, but also directly affects the energy consumption of driving the movement. The robotic arm is moving needs to have good controllability, so it cannot be too bulky. The lighter the weight, the smaller the moment of inertia.

this perspective, steel is the heaviest material, more than 60% heavier than aluminum alloy. High-strength steel reaches 7.8g/cm3, aluminum has 2.7g/cm3. Carbon fiber has the smallest specific gravity, only 1.75g/cm3. Therefore, the robotic arm made of carbon fiber is the lightest of all materials currently available, which can make the robotic arm operation more flexible accurate.

The working environment of the robot arm also puts forward corresponding requirements for the material. For example, in a certain temperature difference, the metal will have corresponding creep. This creep seems to be negligible, but it has a significant impact on the precision of the robot arm's operation. Carbon fiber is different ordinary steel aluminum alloy. It can maintain the minimum creep between minus dozens of degrees 200 degrees Celsius, so it can be used in different working environments. This also makes everyone pay great attention to this robot arm product with many obvious advantages.
