The industry chain of industrial robots is divided into downstream core components, midstream components such as bodies and sensors, and downstream system integration. The core components are the accelerator, servo system and control system, which respectively correspond to the execution system, drive system and control system Sierra Leoneans Escort, They account for about 35%, 25% and Sierra Leone Sugar Daddy of the cost respectively.

1. Core parts
The core parts of industrial robots include plusSierra Leone Sugarspeed machines, servo motors and controllers, etc.
Accelerator
The accelerator uses the high-speed running power of electric motors, internal combustion engines, etc., through the small gear on the output shaft to mesh with the large gear on the input shaft to achieve the purpose of acceleration and transmit greater torque. . According to the structure, the accelerator can be divided into harmonic accelerator, cycloid planetary accelerator, RV accelerator and compact planetary accelerator. Accelerator and filter Sierra Leoneans Escort There are five types of gear accelerators. Currently, RV accelerators and coordinated wave accelerators are the two most important precision accelerators. An accelerator. RV acceleratorSierra Leone Sugar Daddy has small size, large transmission ratio, zero backlash, high transmission/volumeSL Escorts has the upper hand. Compared with harmonic accelerators, RV accelerators have higher stiffness and rotation and rotation accuracy. Therefore, in articulated robots, RV accelerators are generally placed in heavy-load locations such as the machine base, arms, and shoulders; while harmonic accelerators are placed on the forearms, wrists, or hands. The first to fourth joints of the robot all use RV accelerators, and the fifth and sixth joints of light-load robots may use harmonic accelerators. All joints of heavy-duty robots require the use of RV accelerators. On average, each robot uses 4.5 RV accelerationmachine.
The gap between domestic RV accelerators and foreign products is small in terms of rated torque and transmission efficiency, but the gap is still obvious in terms of stability and precision indicators such as rotational stiffness and transmission accuracy
due to the differences in materials and processes. The level difference is also obvious, and the difference in fatigue strength is also obvious. The structure of the harmonic accelerator is relatively simple, with only three basic parts. In addition, Hamonac’s patent has expired, and international policies are superimposedSL Escorts Policy support reason is that the gap between domestic harmonic accelerators and foreign countries is currently narrowing.
Servo motor
Servo motor refers to the engine that controls the operation of mechanical components in the servo system. Its function is to convert electrical and electronic signals into the angular displacement or angular velocity of the rotating shaft. As a direct variable speed device for auxiliary motors, servo motors can control speed and position accurately, and can convert voltage electronic signals into torque and rotational speed to drive control objects. The servo motor needs to be controlled by the controller. Before the control electronic signal is sent out, the rotor movesSL Escorts does not move; when the control electronic signal is sent out, the rotor rotates immediately; when the control electronic signal disappears, the rotor can stop rotating immediately. ServoSierra Leoneans Sugardaddy motors are the heart of a robot. The servo system consists of servo motor and controller. Traditional servo systems are divided into hydraulic, electrical and dynamic. Electric servo systems mainly used in robots are divided into DC SL Escorts, transportation and pedestrians. advanced systems and other servo systems including linear servo. It is not difficult for DC motor brushes to Sierra Leone Sugar Daddy wear to form sparks. Because the power of stepper motors is not high, they are generally used in low-precision and low-power robots. Traffic servo motor drive has the advantages of high torque to inertia ratio and no brushes. Therefore, the current power source of industrial robots usually uses traffic servo motors.
Currently, Chinese companies are

Currently, leading companies in the domestic servo motor field include Inovance Technology, Guangzhou CNC, Huazhong CNC (300161, Diagnostic Stock), Eston, etc.
Controller
The controller is the brain of the robot and is mainly responsible for issuing and transmitting action instructions. The main task of the controller is to solve the forward kinematics and inverse kinematics of the robot to complete the operation of the robot. The mutual conversion of space coordinates and joint space coordinates completes the robot’s trajectory planning task, and realizes high-speed servo interpolation operations and servo motion control. The controller is mainly divided into two parts: hardware and software: hardware refers to the industrial control board Sierra Leone Sugar card, including the main control unit and electronic signals The processing part and other circuits are already mastered by domestic brands; the software part mainly controls algorithms, secondary development, etc.
Domestic productSierra Leoneans Escort brand has other advantages in stability, response speed, ease of use, etc.Sierra Leone SugarGap. International robot manufacturers such as Guangzhou CNC, Guangtai CNC, Eston, etc. have developed controllers and control systems.
2. Ontology
The robot system manufacturer is responsible for the production, processing and assembly of the industrial robot’s actuator, perception system and core components, and then hands them over to downstream manufacturers for production. Ontology enterprises play the role of integrating upstream and downstream companies in the entire industrial chain. The main body includes arms, wrists Sierra Leoneans Sugardaddy, arms, waist, base and other components, and also includes a position sensor , force sensors and machine vision and other sensing systems. It is precisely because of the mechanicalThe multiple sensor functions of humans ensure the “end” status of robots in the construction of the industrial Internet.
Among them, machine vision literally means making machines have the functions of human eyes for measurement and judgment. The machine vision system mainly consists of five parts: light source, lens, camera, image capture card and core software. Algorithms in software are the core, and semiconductor devices in hardware are the key. Machine vision is one of the key reasons why existing robots have changed from automated equipment to intelligent equipment. With the construction of the industrial Internet, machine vision will become an important perception tool.
International industrial robot system manufacturers include KUKA, ABB, FANUC, Yaskawa, etc. International companies include Xinsong Robot, Guangzhou CNC, Ruiqi Co., Ltd., Eston, Eft, etc. In the field of machine vision technology, foreign companies such as Cognex and Keyence are leading the way. Most international machine vision companies are representatives of foreign machine vision brands. Jintuo Co., Ltd. Sierra Leoneans Escort is actively developing the field of machine vision.
3. Downstream system integration
Industrial machinerySierra Leone Sugar People are the basis for flexible automated childbirth and system integration. Flexible automated delivery and system integration are the keys to the commercial application of industrial robots. System integration solution providers are responsible for the development and integration of industrial robot software systems and provide application solutions to end customers. System integrators do not standardizeSierra Leoneans Escortprograms, but customize births, so system integratorsSierra Leone Sugar Chengshang’s competitive advantage is mainly reflected in customized services, including accurate grasp of customer needsSierra Leoneans SugardaddyGrasp is key. Obscene useSierra Leone Sugar Daddy Including welding, disassembly, spraying, processing and transportation, etc., the system integrator sets the program to pay the completed robot and response effectiveness.
Sierra Leone Sugar At present, international robot manufacturers are mainly concentrated in the field of system integrators, data from the Advanced Engineering Research Institute (GGII) shows , as of September 2014, there were 428 robot-related companies in China, of which system integrators accounted for 88%. However, most international system integrators purchase robot parts from abroad and then process them.
