The value of automation and robots in all of the manufacturing industries is growing. Industrial robots have replaced individuals in the wide range of 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 make), assembling, painting, welding, packaging, palletizing, product inspection and testing. Industrial robots are employed within a diverse range 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 line with the definition it can be fixed set up or mobile for use in industrial automation applications. These industrial robots are programmable in three or more axes. They may be multi-functional tools that may be custom-built and developed to perform various operations.
The most important benefits associated with industrial robots is they can be set to suit industry specific requirements and can work continuously for many years, consistently meeting high manufacturing quality standards. The cost-effective lifespan of an industrial robot is roughly 12-16 years. Because of the persistent accuracy industrial robots have become variety section of manufacturing.
Industrial robots has sorted out into different categories depending on their mechanical structure. The most important categories of industrial robots are:
Gantry (Cartesian) Robot: They are stationary robots having three portions of motion. They work from an overhead grid which has a rectangular work envelope. They may be mainly utilized to perform ‘pick and place’ actions. Gantry robots have got all their axes across the work which makes them also suitable 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 factory automation 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 10 or higher interactive joints. Articulated robots are very well suited to welding, painting and assembly.
Basic industrial robot designs could be customized by having different peripherals. End effectors, optical systems, and motion controllers are essential add-ons. End effectors would be the end-of-arm-tooling (EOAT) attached to robotic arms. Grippers or wrenches which are employed to move or assemble parts are types of end effectors. End effectors are made and accustomed to sense and communicate with the external environment. The conclusion effectors’ design depends upon the approval requirements with the specific industry. Machine Vision systems are robotic optical systems. These are built-on digital input/output devices and computer networks employed to control other manufacturing equipment like robotic arms. Machine vision is employed for your inspection of product which like semiconductor chips. Motion controllers are utilized to move robots and position stages smoothly and accurately with sub-micron repeatability.
