The value of automation and robots in every manufacturing industries is increasing. Industrial robots have replaced humans in a wide array of industries. Robots beat 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 place), assembling, painting, welding, packaging, palletizing, product inspection and testing. Industrial robots are utilized in a diverse array of industries including automotive, electronics, medical, food production, biotech, pharmaceutical and machinery.
The ISO definition of a manipulating industrial robot is “an automatically controlled, reprogrammable, multipurpose manipulator”. In accordance with the definition it could be fixed in position or mobile to be used in industrial automation applications. These industrial robots are programmable in several axes. They are multi-functional items that may be custom-built and developed to perform a various operations.
The most important benefits of industrial robots is that they may be designed to suit industry specific requirements and will work continuously for many years, consistently meeting high manufacturing quality standards. The cost-effective life time of your industrial robot is around 12-16 years. Because of the persistent accuracy industrial robots are getting to be an indispensable portion of manufacturing.
Industrial robots are categorized into different categories according to their mechanical structure. The main kinds of industrial robots are:
Gantry (Cartesian) Robot: They may be stationary robots having three elements of motion. They work from an overhead grid with a rectangular work envelope. They are mainly used to perform ‘pick and place’ actions. Gantry robots have all their axes above the work causing them to be also suitable for dispensing applications.
SCARA Robots: (Selectively Compliant Articulated Robot Arm) These robots have 4 axes of movement. They move in the x-y-z coordinated circular work envelope. They are used for factory automation requiring pick and put work, application and assembly operations and handling machine tools.
Articulated robots: An articulated robot has rotary joints. It might have from two to ten or more interactive joints. Articulated robots are very fitted to welding, painting and assembly.
Basic industrial robot designs might be customized by having different peripherals. End effectors, optical systems, and motion controllers are essential add-ons. End effectors will be the end-of-arm-tooling (EOAT) attached to robotic arms. Grippers or wrenches which can be utilized to move or assemble parts are examples of end effectors. End effectors are created and accustomed to sense and communicate with the external environment. The finish effectors’ design depends upon the approval requirements from the specific industry. Machine Vision systems are robotic optical systems. They are built-on digital input/output devices and computer networks accustomed to control other manufacturing equipment for example robotic arms. Machine vision is used to the inspection of manufactured goods such as semiconductor chips. Motion controllers are used to move robots and position stages smoothly and accurately with sub-micron repeatability.
