The value of automation parts in most manufacturing industries is growing. Industrial robots have replaced people in numerous industries. Robots out perform humans in jobs that need precision, speed, endurance and reliability. Robots safely perform dirty and dangerous jobs. Traditional manufacturing robotic applications include material handling (pick and set), assembling, painting, welding, packaging, palletizing, product inspection and testing. Industrial robots are being used in a diverse variety of industries including automotive, electronics, medical, food production, biotech, pharmaceutical and machinery.
The ISO concept of a manipulating industrial robot is “an automatically controlled, reprogrammable, multipurpose manipulator”. In accordance with the definition it may be fixed into position or mobile for use in industrial automation applications. These industrial robots are programmable in three or more axes. They can be multi-functional items that can be custom-built and programmed to carry out a assortment of operations.
The most important advantages of industrial robots is that they might be programmed to suit industry specific requirements and might work continuously for a long time, consistently meeting high manufacturing quality standards. The economic life time of any industrial robot is approximately 12-16 years. Because of their persistent accuracy industrial robots are becoming an indispensable a part of manufacturing.
Industrial robots are classified into different categories based on their mechanical structure. The main groups of industrial robots are:
Gantry (Cartesian) Robot: They are stationary robots having three elements of motion. They work from an overhead grid by using a rectangular work envelope. These are mainly employed to perform ‘pick and place’ actions. Gantry robots have got all their axes above the work causing them to be also well suited for dispensing applications.
SCARA Robots: (Selectively Compliant Articulated Robot Arm) These robots have 4 axes of motion. They move within an x-y-z coordinated circular work envelope. They are utilised for proximity sensor requiring pick and put work, application and assembly operations and handling machine tools.
Articulated robots: An articulated robot has rotary joints. It may have from two to ten or higher interactive joints. Articulated robots are suitable for welding, painting and assembly.
Basic industrial robot designs might be customized with adding different peripherals. End effectors, optical systems, and motion controllers are essential add-ons. End effectors would be the end-of-arm-tooling (EOAT) connected to robotic arms. Grippers or wrenches that are widely used to move or assemble parts are types of end effectors. End effectors are hc03bt and employed to sense and connect with the external environment. The final effectors’ design depends on the application form requirements from the specific industry. Machine Vision systems are robotic optical systems. They can be built-on digital input/output devices and computer networks accustomed to control other hc152t-sz like robotic arms. Machine vision is commonly used for that inspection of manufactured goods such as semiconductor chips. Motion controllers are employed to move robots and position stages smoothly and accurately with sub-micron repeatability.
