What effect will multiple industrial robots work together?

- Oct 22, 2019-

Since the birth of industrial robots, they have been widely used in many industrial fields. The labor environment of some factories is too extreme for people's physical requirements. People's flesh and blood are incapable, or the process requirements for certain types of work are very high. High and human manual work can not reach the standard and other scenes.


Industrial robots were first used in the automotive industry, often used in welding, painting, loading and unloading. With the extension and expansion of the application of industrial robot technology, it is now possible to replace heavy and monotonous repetitive work and replace labor in hazardous environments such as dangerous, harmful, toxic, low temperature and high heat, and improve labor productivity. Guarantee product quality. Industrial robots and CNC machining centers, automatic handling trolleys and automatic inspection systems can be combined to form flexible manufacturing systems (FMS) and computer integrated manufacturing systems (CIMS) for production automation. Industrial robots are mainly used in the following aspects:


Poor working environment and dangerous work. Industrial robots can be used as substitutes for people, such as die-casting workshops and nuclear industries, which are harmful to health and life-threatening, or unsafe factors that are suitable for people to do, such as the boiling water reactor fuel automatic switch in the nuclear industry. Special work and extreme work. Robots can be used for volcanic exploration, deep sea exploration and space exploration, which are beyond the reach of humans, such as the operating arm used to recover satellites on the space shuttle.


Automated production areas Early industrial robots were mainly used for machine loading, unloading, spot welding and painting. With the advent of flexible automation, robots have played a more important role in the field of automated production. Here are some examples:


1) Welding robot. The arc welding robot requires six degrees of freedom. Three degrees of freedom are used to control the spatial trajectory of the welder following the weld. The other three degrees of freedom maintain the correct attitude relationship between the weld and the surface of the workpiece, thus ensuring good weld quality. . This type of robot is widely used in automotive manufacturers to weld large beams and body structures.


2) Material handling robot. Material handling robots can be used for loading and unloading, palletizing, unloading, and grabbing part orientation. 3) Detection. In the part manufacturing process, engineering inspection and finished product inspection are the key processes to ensure product quality. The test content mainly includes: confirming whether the part size is within the allowable tolerance; the control parts are classified by quality.


4) Assemble the robot. Assembly is a more complicated process, not only to detect errors during assembly operations, but also to try to correct such errors. Therefore, many sensors are used on the assembly robot, such as contact sensors, vision sensors, proximity sensors, and auditory sensors. The hearing sensor is used to determine if the press-in or slide-in is in place.


5) Painting and spraying. There must be at least five degrees of freedom when performing three-dimensional surface painting and painting operations. Due to the presence of a flammable environment, the drive must be flameproof and explosion proof. When working on large parts, the robot is often mounted on a rail to walk.


By applying the advantages of robots, through the introduction of robot application fields, we can know that robot applications bring the following benefits to humans: (1) Reduce labor costs. (2) Improve productivity. (3) Improve product quality. (4) Increase the flexibility of the manufacturing process. (5) Reduce material waste. (6) Control and speed up the turnover of inventory. (7) Reduce production costs, and (8) eliminate dangerous and poor labor.
