Research on Three-Position and Parallel System of Inspecting the Automotive Piston Rings

Abstract:

The paper proposes an efficient system to inspect the automotive piston rings. The width of end gap and the degree of light leakage are two significant parameters of the piston ring that must be controlled in a certain range. Due to the small size of automotive piston rings and the large quantity, the paper uses the vision system and image processing tools to detect the piston rings with 80.5mm diameter. The uncertainty of inspecting end gap and light leakage can reach 0.01mm and 2° respectively. In order to improve the inspection efficiency, the paper uses three-position and parallel system, end gap and light leakage are inspected at the same time, it can detect 10 pieces/min.
