Industrial robots are multi-articulation manipulators or multi-free robots in the industrial field. An important development of the future manufacturing industry is that industrial robots have now replaced the entire production, which is the foundation for the completion of intelligent production, and will ensure the completion of industrial automation, digitalization and intelligence in the future. Poor production and processing environment, aging population leads to labor shortage and high labor training costs, which increases the demand for industrial robots. What is the fundamental composition and classification of industrial robots?
Consists of fundamental industrial robots
The industrial robot is composed of three parts: the main shell, the drive system and the control system.
Body: seat and driver, including hands, wrists and hands, some robots and walking tissues. The wrist part is also known as the external east-west interface of the terminal and can be used to mount fixtures, things, sensors, etc.
Drive system: Contains the power supply and transmission organization that enables the driver to perform such actions.
Control system: send control signals to the drive system, drive according to the input program, and drive the industrial robot according to the needs.
Classification of industrial robots
Classification is based on a common coordination table
PPRectangular Coordinate Robot, also known as a single-axis manipulator, changes the spatial orientation of the terminator to complete the straight axis movement of x, y, and z.
Cylindrical Coordinate Robot (RPP)
The spatial orientation of the end of the robot is changed by two moving coordinates and one rotation coordinate.
Spherical Coordinate Robot (RRP)
The movement of the robot hand, also known as polar coordinates, consists of linear motion and two rotations, i.e., stretching along the x-axis, rotating along the y-axis, and rotating along the z-axis.
Articulation Robot (RRR)
It is also known as articulated manipulator or articulated manipulator and is used in many industrial fields, such as automatic installation, painting, transfer, welding, etc. It is divided into straight articulation robots and planar (horizontal) articulation robots.
In addition, it can also be classified according to the functional characteristics of articulation robots, such as transfer robots, stacking robots, welding robots, painting robots, laser cutting robots, etc.
Classified by the number of robot axes
Six traditional members
The six-axis robot has six continuous rotary connections, and the traditional six-link robot can be divided into ordinary six-link robot and special six-link robot.
7-axis robot
It is also known as a redundant robot. Compared to a six-axis robot, the rated axis allows the robot to avoid specific policies, facilitate the activation of the terminal in a specific direction, and adapt more flexibly to a specific working environment.
Collaborative robots
Abbreviated as cobot or co-robot. It is a robot that is able to communicate/contact people directly and securely. Cobots are able to combine the precision and repeatability of a robot with the unique skills and abilities of humans. People excel at solving inaccuracies and uncertainties, and robots have the advantage of precision, strength, and durability.
Four-axis/SCARA robot
Quadruple robot means that the arm of the quadcopter robot can move freely on a few planes. The "Articulation Manipulator" is optional, i.e. traction freedom in the X, Y, and Z directions, and rotation freedom in the Z direction.
Delta Parallel Robot
The Delta robot is a fast, light-payloaded, parallel robot that typically learns programming or vision to hit the course. The center of the grip is confirmed by three parallel marginal axes (TCP), which complete the transfer and processing of the guideline object.
Classified by control system
Classification is based on whether there is a reaction or not
It is divided into open-circuit control and closed-circuit control
Categorized by the amount of expected manipulation
It is divided into force manipulation, azimuth manipulation, and hybrid manipulation
Force manipulation is divided into direct force manipulation, impedance manipulation, and mixed force horizontal manipulation
Azimuth manipulation is divided into: manipulating one articulation direction (azimuth response, azimuth velocity response, azimuth-velocity-acceleration response) and manipulating multiple articulation directions
After intelligent processing
It is divided into fog manipulation, adaptive manipulation, optimal manipulation, neural network manipulation, fog network manipulation, and expert manipulation

The way to reduce spatter – OTC welder
1. Adjust the arc voltage
If the settings are incorrect, the voltage setting will significantly add to the spatter. The low voltage setting can cause spatter as the wire is repeatedly short-circuited in the weld pool, resulting in a small burst at the wire tip.
This short circuit is normal for short arc MIG welding, but ...
