随着手机拍照要求和性能的提升, 相位检测自动对焦(PDAF)类模组广受关注。由于手动方式测试此类模组测试效率低、测量精度低、工人劳动强度大等不足, 结合实际生产情况, 综合机械设计、机械理论、工程材料等相关知识, 通过理论计算与实际模拟相结合的方式, 设计并制造了 1台三工位自动对焦设备, 其实际生产效率能够达到 210 片/h。为了更好地提高工作效率, 进一步将三工位自动对焦测试设备改造成六工位自动对焦设备, 改造后生产效率能够达到 360 片/h, 测试效率提升了 70%左右。

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%.
