Robust layout design of pin-hole locators in head lampshade assembly process is presented based on Taguchi orthogonal experiment and 3DCS. Firstly, based on the 3-2-1 locator principle of three dimensional assembly process, the influence of pin-hole locators design parameters on the variation of assembly part is analyzed and the pin-hole locators design parameters level of head lampshade is determined. Then, Taguchi orthogonal experiment is arranged considering the pin-hole locator coordinates of head lampshade as design parameters and locating variation as noise parameters. A robustness evaluation function of assembly quality is proposed considering the assembly clearance between turn light and headlight as evaluation index. Following, the SNR calculation method of robust layout design for pin-hole locators is proposed. Finally, 3DCS is used to analyze the robustness of assembly quality with variation parameters under pin-hole locator schemes. The results show that, compared with Taguchi original design scheme, the mean value of measure point in robust design scheme is decreased by 22.48%.
