In the modern era of technology, one cannot lack behind in terms of any advancements. Step by step progressing of industries allows them to be more competitive. In this aspect, industrial robots hold prime importance. An industrial robot can be referred as a robot arm or robot system used for manufacturing and formulating purposes used in a factory environment. The different types of industrial robots can be classified on the basis of different criteria such as application (hand tools, mining tools, fitting parts, CNC,etc.), degree of freedom (axes), brand and architecture (parallel or serial). These robots are programmable, automated and capable of movement on three or more axis. Let’s list down a few of the most important robots that you must be aware of:
Today whenever people talk about industrial robots, they are mostly referring to articulated robots as they are commonly used in factories. These robots have a large work envelope and can be used for several applications like material handling, dispensing, welding and material removal applications. They make the manufacturers more appealing and versatile due to more degrees of freedom they provide than any other robot. They usually have four to six-axis but can be moved up to 10. It improves the quality of the product it produces through its improved accuracy and speed. They gained popularity in the market because of their longevity and affordability.
SCARA robots are all in one robot that can tackle any complexities by its ready-to-go rotary motion package and end-of-arm tooling. The two-parallel joints featured by SCARA provide compliance in one selected plane. They are imperative to the electronics industry because of their capability to handle tiny and fragile parts by their precise and gentle arm. The exceptional range of motion and greater flexibility enables them to support the electronic industry and provide increased throughput and a fast ROI. Because of their work envelope and easy integration, they are also used in Biomed applications. The cleanroom SCARA robots are also used for jobs such as fiber optics and safeguard the deployment of the corrosive, dusty or underwater environment.
They are also called gantry or rectilinear robots because they have three linear joints that use the Cartesian system. As they are easy to use and program, these robots are commonly used for the majority of industrial applications. Plant operators often make use of these robots because of their ability to meet specific application needs by the flexibility in the configuration. It also fits best with the pick and place applications and is also famous because of their highly customizable tendency.
These robots are widely used for many industrial purposes because of increased arm-rigidity with faster cycles and increased stability. They have several yet simple lightweight arms, which are controlled by its own motor, between moveable part and the fixed base. Because of their compact and lightweight architecture, safety and easy sterilization, Parallel robots are widely used for medical applications. Parallel robots are also used for different operations like welding, assembly, deburring, packaging, and material handling. It vitalizes smooth motion and high throughput and also helps to save time between operations. One kind of parallel robot used for pick-and-place purpose is Delta robot.
Cylindrical robots have at least one prismatic joint (moving in linear motion) to connect the links and at least one rotary joint (using rotational motion along the joint axis) at the base. They are very simple and operate with a cylindrical work envelope. Cylindrical robots are best suited for assembly operations, spot welding, handling die casting machine and other machine tools. They can work best in simple applications like picking up material, rotating and then placing it for work.
To choose the best industrial robot, one must take into consideration the specific features and applications: orientation, precision, speed, load and duty cycle. When the robots are selected for particular work purpose depending upon their proficiency, the very selection ensures most effective and efficient results.
