Practice has proven that multi-axis robots are mainly used in mechanical structures with high precision requirements. Their moving and stationary components do not require an intermediate medium, but instead use rolling steel balls, thus meeting the precision requirements. Currently, with the continuous expansion of industries such as my country's power industry and urban rail transit, the demand for multi-axis robots is also growing rapidly. So, what are the components of a functional multi-axis robot?
1. Actuation Mechanism: The actuator mechanism of a multi-axis robot is an important part of the execution process. It includes components such as the hand, wrist, arm, and column. During operation, the hand comes into contact with the object. Depending on the way the object is touched, there are different hand methods such as gripping and suction. Through the combined effect of these components, the object is grasped and transported to the designated position.
2. The drive system is the transmission device used by a stable multi-axis robot to drive the execution mechanism to perform accurate movements. Generally speaking, the drive system of a multi-axis robot is divided into four different types: hydraulic transmission, pneumatic transmission, electric transmission, and mechanical transmission.
3. Control System: Multi-axis robotic arms have two types of control systems: electrical control and jet control. The electrical control system is the most common. It is a crucial component of the robotic arm, capable of controlling the multi-axis robotic arm to move according to a set program. It can also memorize the operator's instructions, such as the sequence of actions, movement trajectory, speed, and timing. Furthermore, it can issue commands to the actuators based on the control information, and can monitor the robotic arm's movements when necessary, issuing alarm signals when errors or malfunctions occur. In addition to these three components, multi-axis robotic arms also have position detection devices that can feed back the actuator's position to the control system, compare and adjust it based on the set information, thus ensuring accurate movement of the multi-axis robotic arm. It is precisely because of these well-designed components that robotic arms can provide higher levels of intelligence for enterprise production.
Single-axis and multi-axis robotic arms are high-tech automated production equipment that have developed in recent decades, and are also an important branch of industrial robots. The accuracy of operation and the ability to complete tasks in various environments using miniature electric single-axis and multi-axis robotic arms have promoted industrial development. Below, we will learn about the components of a high-quality single-axis and multi-axis robotic arm.
1. The execution mechanism of a single-axis or multi-axis robotic arm consists of a hand, wrist, arm, and support column. The hand is the gripping mechanism used to clamp and release workpieces, similar to human fingers, and can perform similar movements to human hands. The wrist is the component connecting the fingers and arm, capable of up-down, left-right, and reverse movements. Simple robotic arms may not have a wrist. The support column of the single-axis arm is used to support the arm and can also be made movable as needed.
2. The actions of the actuators are completed by the transmission system. Commonly used single-axis and multi-axis robot transmission systems include mechanical transmission, hydraulic transmission, pneumatic transmission, and electric transmission, which can distribute the power generated by the transmission system to the various components of the actuator.
3. Control System: The main function of a single-axis or multi-axis robot control system is to control the robot to move according to a certain program, direction, position, and speed. Simple robots generally do not have a dedicated control system; instead, limit switches, relays, DC/AC robot control valves, and circuits are used to control the drive system, enabling the actuator to move as required. Robots with complex movements require programmable controllers or microcomputers for control.
These are some of the key components of a single-axis or multi-axis robotic arm. For a robotic arm to mimic the movements of a human arm, these components need to work in perfect harmony to accurately execute pre-programmed actions and complete various production tasks. However, it's important for companies to research which manufacturers offer high-quality single-axis or multi-axis robotic arms before making a purchase to ensure the robotic arm they use achieves more accurate execution.
