The wrist is the part that connects the arm and the end effector, and it can perform movements such as rotation and swinging. The design of the wrist needs to take into account the robot's flexibility and precision requirements.
1.4 End effector
The end effector is the part of an industrial robot that comes into contact with the workpiece; it can be a gripper, suction cup, nozzle, etc. The design of the end effector needs to be customized according to the robot's application scenario and the characteristics of the workpiece.
Joints and transmission mechanisms
Joints and transmission mechanisms are key components for industrial robots to achieve movement, including rotary joints, linear joints, and various transmission mechanisms.
2.1 Rotational Joint
Rotary joints are components in industrial robots that enable rotational motion, typically employing harmonic reducers, RV reducers, or planetary reducers. The design of rotary joints must consider factors such as load capacity, precision, and lifespan.
2.2 Linear Joints
Linear joints are components in industrial robots that enable linear motion, typically employing ball screws, linear guides, or hydraulic cylinders. The design of linear joints requires consideration of factors such as motion speed, load capacity, and precision.
2.3 Transmission Mechanism
The transmission mechanism is the component that connects the joint and the actuator, and can be a gear, belt, chain, etc. The design of the transmission mechanism needs to take into account factors such as transmission efficiency, noise, and lifespan.
sensor
Sensors are key components for industrial robots to perceive their environment and workpieces, including position sensors, force sensors, and vision sensors.
3.1 Position Sensor
Position sensors are used to detect the angles and positions of robot joints, and typically employ photoelectric encoders or magnetic encoders. The design of position sensors needs to consider factors such as accuracy, resolution, and interference immunity.
3.2 Force Sensor
Force sensors are used to detect the contact force between a robot and a workpiece, and typically employ strain gauges or piezoelectric sensors. The design of force sensors needs to consider factors such as sensitivity, linearity, and stability.
3.3 Vision Sensor
Vision sensors are used to acquire image information of workpieces, typically employing cameras or laser scanners. The design of vision sensors needs to consider factors such as resolution, frame rate, and interference resistance.
controller
The controller is the brain of an industrial robot, responsible for receiving sensor signals, processing data, and outputting control commands. Controller design needs to consider factors such as real-time performance, stability, and scalability.
4.1 Main Controller
The main controller is the core control unit of an industrial robot, typically employing a PLC or embedded system. The design of the main controller needs to consider factors such as processing power, communication interfaces, and software support.
4.2 Motion Controller
The motion controller is responsible for implementing the robot's motion control, including speed control, acceleration control, and position control. The design of the motion controller needs to take into account factors such as control algorithms, accuracy, and response speed.
4.3 Safety Controller
The safety controller is responsible for implementing the robot's safety protection functions, including emergency stop, collision detection, and area restriction. The design of the safety controller needs to take into account factors such as reliability, response time, and user interface.
Software System
The software system is the nervous system of an industrial robot, including the operating system, programming language, and application software.
5.1 Operating System
The operating system is the fundamental software platform for industrial robots, typically employing real-time operating systems or embedded operating systems. Operating system design must consider factors such as real-time performance, stability, and compatibility.
5.2 Programming Languages
Programming languages are the programming tools for industrial robots, including C/C++, Python, and Java. The design of programming languages needs to consider factors such as ease of use, flexibility, and scalability.
5.3 Application Software
Application software is the tool used by industrial robots, including robot programming software, vision software, and simulation software. The design of application software needs to consider factors such as user interface, functional modules, and compatibility.
Power System
The power system is the power source for industrial robots, including power modules, batteries, and cables.
6.1 Power Module
Power modules are the power conversion and distribution components of industrial robots, typically employing switching power supplies or linear power supplies. The design of power modules must consider factors such as efficiency, stability, and safety.
6.2 Battery
Batteries serve as backup power for industrial robots and are typically made of lithium-ion or nickel-metal hydride. Battery design must consider factors such as capacity, lifespan, and safety.
6.3 Cables
Cables are power transmission components for industrial robots and must meet the robot's motion and electrical performance requirements. Cable design needs to consider factors such as flexibility, abrasion resistance, and interference resistance.
