Introduction to industrial robot knowledge!

Industrial robots are widely used in industrial manufacturing, such as automobile manufacturing, electrical appliances, food, etc., can replace repetitive machine operation tasks. It is a machine that relies on its own power control capabilities to complete various functions. It can accept human command can also operate according to pre-arranged programs. Today we will talk about the basic primary components of industrial robots .

1. Industrial robot body

 The main body of the industrial robot is the base actuator, including the industrial robot arm, industrial robot forearm, industrial robot wrist hand, which constitute a multi-degree-of-freedom mechanical system. Some robots have another walking mechanism. Industrial robots have 6 degrees of freedom, even more. The wrist generally has 1 to 3 degrees of freedom of movement.

2. Industrial robot drive system

The drive system of industrial robots is divided into three categories according to the power source: hydraulic, pneumatic electric. Based on the needs, the composite drive system can also be combined these three types. it can be driven indirectly by mechanical transmission mechanisms such as synchronous belts, gear trains, gears. The power device transmission mechanism are what the drive system must have in order to complete the corresponding movement of the mechanism. Each of these three basic drive systems has its own characteristics. The current mainstream is the electric drive system.

Because of the small inertia, high-torque AC DC servo motors their supporting servo drives are widely accepted. This type of system does require energy conversion, is easy to use, has sensitive control. Most motors need to be equipped with a sophisticated transmission mechanism: a reducer. Its teeth use a gear ratio converter to reduce the number of reverse rotations of the motor to the required number of reverse rotations, obtain a larger torque device, thereby reducing speed, increasing torque, blindly increasing the servo motor when the load is large. The power cost-effectiveness is very high, the output torque can be improved through the reducer within the appropriate speed range. Servo motors are prone to heat low-frequency oscillation when running at low frequencies. Long-term repetitive work is conducive to ensuring its accuracy reliable operation. The existence of a micro-reduction motor enables the servo motor to run at a suitable speed, while outputting greater torque enhancing the rigidity of the body. There are currently two mainstream reducers: harmonic reducers RV reducers

3. Industrial robot control system

The robot control system is the brain of the robot the primary component that determines the robot's functions capabilities. The control system receives command signals controls the drive system execution mechanism according to the input program. The primary mission of industrial robot control technology is to control the range of motion, posture, trajectory, action time of the industrial robot in the workspace. It has the characteristics of simple programming, software menu operation, friendly human-computer interaction interface, online operation prompts, convenient operation.
