Robots
Industrial robots are being used for a wide variety of tasks in factories, shops and foundries around the world. Robots unload parts from the casting machines and plastic injection molding machines. They load and unload parts at machine tools and stamping presses; transfer parts from die to die or from press to press. In die casting and plastic injection moulding operations, a robot may unload a single machine or as many as three machines. In machine tool loading and unloading, the robot may also tend more than one machine-loading and unloading each in turn, or on demand and transferring pasts from machine to machine, as well as placing parts in gases for dimensional checking.
In forging operations, robots are used to transfer hot billets from furnaces to forging presses, to transfer pasts from die to die in successive forming operations and to handle hot and cold parts in trimming operations. Robots are also used in casting clean-up operations, handling cutting torches or abrasive cut-off wheels to remote gates and risers and for grinding flash from parting lines.
Continuous-path servo-controlled robots are used for spraying a wide variety of parts and materials; for spot and arc welding. Robots are used for drilling and grinding, handling either the parts or a power tool.
In assembly operations, the microprocessor-controlled robot with sensory feedback capability performs the complex part and toll-handling tasks.
