The design of the main content is to select and design the appropriate agency, design a multi-position bench for the overall layout and draw the cycle diagram. The main task is to complete draw up the material on table of the work-piece, injection fluid coating, drying, cutting and other six processes, drying process takes three processes. The design requirements for cycle of single-piece production is 12s, craft processing time is not less than 2s. The six-station rotary table with stepper motor by controlling the stopping method to achieve transposition table and positioning, by controlling the input number and frequency of electrical pulses to achieve the angular displacement and speed table, by a stepping motor drive wheel to move the work-piece, the work-piece holder is rotated to the corresponding processing station. Because the stepper motor itself has a good self-locking function during machining of the work-piece, so the turntable occur rotated to ensure accurate positioning during the entire process, and so the process for the work-piece has a better quality.
