Focusing mechanism is an important part of zoom lens in production manufacturing engineering, in order to meet the reading and detection of anti-counterfeiting label laser anti-counterfeit platform, this paper presents the principle and method of using linear driving mode focusing and introduces the focusing mechanism which consists of a stepping motor, linear guide rail, rail screw or gear rack, the DSP controller. By contrast test, it verifies the location precision ball screw type focusing mechanism for 0.061 ~ 0.067 mm which higher than the design requirements and it is suitable for use in laser anti-counterfeit authentication system in production manufacturing engineering.
