Sensors Used in Automotive Paint Shops

Abstract

Paint job can be considered as the heart of the automobile manufacturing process from the customer’s point of view. Automobile manufacturing companies spend a hefty amount on the process at times even more than the body itself. Paint process in an automobile is thus a rigorous and time-consuming process involving: pre-treatment, electrodeposition, sealing, priming, coating and then finally inspection. In a typical car manufacturing plant, more than 1000 cars are processed each day. This high quantum and superior quality standards have forced manufacturers to invest and maintain automated modern production line. Sensors and robots are thus employed at each step of the manufacturing process. This review focuses on the sensors used in the paint job, type, and their importance at each step.
