With the improvement of mobile phone camera requirements and performance, phase detection autofocus (PDAF) module has gradually become the main stream of the market. At this stage, most small and medium-sized module manufacturers still use manual methods to test such modules, and the test efficiency is very low. In order to improve such drawbacks as low test efficiency, low measurement accuracy, and high labor intensity by the manual test equipment, based on the actual production situation, we comprehensively use mechanical design, mechanical theory, engineering materials, and other related knowledge to design and manufacture a three-station autofocus equipment through the combination of theoretical calculation and actual simulation. Actual production verifies that the production efficiency can reach 210 pieces/h. The three-station autofocus test equipment is optimized and modified into a six-station autofocus device, whose production efficiency can reach 360 pieces/h,and the test efficiency increases by about 70%.
