List five applications that a continuous path robot could do that a point-to-point robot could not do.
1)Welding :-There are various types of welding, spot welding, electrical welding and wind welding, etc. IR is often used to operate spot welding. Spot welding is suitable for joining two pieces of steel plates. Its working principle is that the two pieces of steel plates are first joined by two electrodes, a large current is produced when pressure is added. As the electrical energy of the current melts the metal on the joints, they are then joined together rapidly. Generally, there are more than several thousands of welding joints in a car. If the process is done manually, the quality may be unstable. Therefore, robots are more suitable for this kind of repetitive work
2)Painting:- a robot paints cars in the production line with a spray gun. Using robots with continuous path operation mode, robots can spray the paint quickly and evenly on the car, so it can improve the quality of the cars.
3)Assembling components:-Besides handling materials, robots are used to assemble components. For instance, robots can use the suction pad to assemble the window on the car. Using robots to assemble the machines has a lot of advantages. For example, robots can maintain stable production. They ensure the hygiene and can work under dangerous circumstances.
4)Load and unload of cutting tools:-If a worker is responsible for the loading and unloading of cutting tools, the machines and the connected parts has to stop to ensure the safety for the worker. If a robot works with the machineries instead, only the clamp tip has to stop operating. Other procedures can continue to operate. If the load and unload commands are preset in the program of the robots, the robots can take out the cutting tools quickly, replace the cutting tools on the clamp tip and put the old ones back to the cutting tools storage. This process only takes about a few seconds. After replacing the cutting tools, the machineries can start again. Therefore, the use of robots has shortened the time of changing cutting tools
5)Cast treatment:-Moulding is the process of injecting the melting metal into a mould. When the metal cools down, the desired product is produced. Since the materials for moulding and the product are very hot, the workers may get hurt. Therefore, robots are used to pour the melted metal, handle the finished products and carry out initial treatment of the surface. Robots can work 24 hours a day, so the production cost is lower though the machineries are very expensive.
