The design skills of Industrial robot arm

In the highly competitive market, the traditional production mode has been unable to meet the modern production needs of enterprises, and many industrial robot systems have joined the production line. Robotic arms are an important part of industrial robots, so special attention is required during the design process. Now let's talk about the robotic arm design skills. The design of the robot arm needs to pay attention to the structural design. How to design the structure? The structural design of the robot arm also has certain attention. Because the open chain mechanism is equivalent to a series of cantilever rods connected in series, the accumulation of mechanical errors and elastic deformation makes the robot The rigidity and accuracy of the arm are greatly affected, so special attention should be paid to the design of stiffness and precision when designing the robot arm. Then the robot arm is a typical mechatronic product. In the structural design, the drive and control must be considered. The problem is different from the general mechanical product design; in addition, compared with the general mechanical products, the mechanical design of the robot arm has higher requirements in terms of compactness and dexterity of the structure.
There are many differences between the design of the tandem robot arm and the general mechanical design. First, from a mechanical point of view, the structure of the robotic arm is an open kinematic chain that is connected by a series of links through a rotating joint. The open-chain structure makes the motion analysis and static analysis of the robot arm complicated, the pose relationship between two adjacent member coordinate systems, the relationship between the position of the end effector and the joint variables, and the force of the end effector. The relationship between the driving torque of each joint and the like is not solved by the general mechanism analysis method. It is necessary to establish a kinematics and static method for the space open chain mechanism.
Industrial robots are widely used in the production field, and can replace high-risk, difficult, repetitive and boring work, reduce human labor intensity and improve production efficiency. It is an indispensable automatic production equipment in modern production process.
