AUTOMATION & PAINT ROBOTS How to decide when it's time to upgrade or replace your robot Imagine you are a Formula One racing team owner who has just developed the world’s best racing car. Elated from winning everything going, you decide not to make any changes, continuing to field the same vehicle, race after race, year after year. Pretty soon, your team starts to slip down the finishing order, as the technology used by other teams not only catches up, but overtakes yours. Plugged full of the latest technology, your car wins every race during its first few years, establishing your team as the outright leader. Although robotic technology moves at a much slower pace than Formula One racing, the same basic principle applies. While the number of industrial robots being deployed in the UK is increasing, over half of those currently installed may well be reaching the end of their useful serviceable lives. In the last 10 years, there have been remarkable advances in the accuracy, speed, intelligence and reliability of robotic automation. As technology moves on, the sourcing of older components needed for an old robot can become increasingly difficult and expensive, until eventual obsolescence makes it virtually impossible for an older robot to remain in reliable working order. requirements relating to uptime and reliability and the budget available. Refurbish or replace? Refurbishment offers a cheaper option to replacing a robot altogether, with your robot able to be returned to a ‘like-new’ condition. Where this option is chosen, it is advisable to use the manufacturer that supplied the robot in the first place as they will be best placed to have the necessary original parts and spares needed to carry out the refurbishment. Of course, you only have to look at the example of the iPhone to see how yesterday’s state of the art gadget can quickly become outdated. Originally launched in 2007, the iPhone is already in its fifth incarnation, with capabilities far exceeding those of the original model. The same is true of robots. The current generation of controllers, software and accessories such as vision and gripping systems are far in advance of their forbears, such that it may eventually be both more practical and less costly in the long term to opt for a new model rather than refurbishing an existing one or buying second hand. Taking the risk by purchasing components from sources other than the robots’ original manufac-turer or using spares from decommissioned units can be a liability to the production line. The quality of the products can be compromised as well as the efficiency and the safety of the robot. Particularly for just-in-time applications, the unexpected failure of a component can cause expensive and potentially catastrophic downtime. Keeping pace therefore means choosing between either replacing or refurbishing your robot. There are a number of factors that can determine this choice, including the nature of your application together with any 40 May 2014 Without a doubt, robots are the answer to staying ahead in today’s manufacturing race. In choosing whether to refurbish or replace your robot, the only question is how much you want to open up the gap between yourself and your competitors. Open until 30th October 2014, the scheme is part of ABB’s drive to encourage the greater take-up of modern robotic automation in the UK manufacturing sector. ABB has launched a new swappage scheme to promote greater use of the latest robotic automation technology amongst UK manufacturers. Subject to the payload of the robot, the Robot Swappage Scheme entitles operators to a discount of up to £4,000* on the purchase cost of a new ABB robot when they trade in an existing robot from any manufacturer installed 12 or more years ago.
