The necessity of automation parts in every manufacturing industries is increasing. Industrial robots have replaced human beings in a wide variety of industries. Robots out perform humans in jobs which need precision, speed, endurance and reliability. Robots safely perform dirty and dangerous jobs. Traditional manufacturing robotic applications include material handling (pick and place), assembling, painting, welding, packaging, palletizing, product inspection and testing. Industrial robots are utilized within a diverse selection of industries including automotive, electronics, medical, food production, biotech, pharmaceutical and machinery.
The ISO concise explanation of a manipulating industrial robot is “an automatically controlled, reprogrammable, multipurpose manipulator”. According to the definition it could be fixed in place or mobile for use in industrial automation applications. These industrial robots are programmable in three or maybe more axes. They can be multi-functional pieces of equipment that can be custom-built and programmed to perform a variety of operations.
The most important advantages of industrial robots is simply because they could 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 the industrial robot is roughly 12-16 years. Because of the persistent accuracy industrial robots are getting to be an indispensable a part of manufacturing.
Industrial robots are classified into different categories based on their mechanical structure. The major categories of industrial robots are:
Gantry (Cartesian) Robot: They may be stationary robots having three aspects of motion. They work from an overhead grid using a rectangular work envelope. These are mainly used to perform ‘pick and place’ actions. Gantry robots supply their axes over the work making them also ideal for dispensing applications.
SCARA Robots: (Selectively Compliant Articulated Robot Arm) These robots have 4 axes of motion. They move in an x-y-z coordinated circular work envelope. They are used for proximity sensor requiring pick and place work, application and assembly operations and handling machine tools.
Articulated robots: An articulated robot has rotary joints. It can have from two to ten or even more interactive joints. Articulated robots are well designed for welding, painting and assembly.
Basic industrial robot designs could be customized with the addition of different peripherals. End effectors, optical systems, and motion controllers are crucial accessories. End effectors are the end-of-arm-tooling (EOAT) mounted on robotic arms. Grippers or wrenches that are employed to move or assemble parts are types of end effectors. End effectors are hc03bt and utilized to sense and connect with the external environment. The end effectors’ design is dependent upon the applying requirements of the specific industry. Machine Vision systems are robotic optical systems. These are built-on digital input/output devices and computer networks accustomed to control other ha103nc-s like robotic arms. Machine vision is used for that inspection of manufactured goods including semiconductor chips. Motion controllers are used to move robots and position stages smoothly and accurately with sub-micron repeatability.
