Demand for plastic molded parts is on the increase in the automobile industry, since they can reduce the costs and total weight of an assembled car without lowering its structural performance. However, burrs are commonly found on the exterior of injection molded parts and these need to be removed. The burrs can be removed manually but, the manual operations are very labor intensive, require highly skilled staff and can be hazardous due to the dust that is generated. This paper presents a study on an automatic deburring system for injection molded, automobile parts, by using a 3-axis robot arm. The system is composed of a robot arm for removing burrs, a pallet and a conveyer for transferring the parts, a pneumatic clamp for fixing of the parts, and a programmable logic controller for performing the overall system control. An example is shown for injection molded parts of an automobile to demonstrate the effectiveness of the developed system.
