Currently, most smart phones are equipped with touch screens. It can be said that the sensitivity of the touch screens directly affects the user's sense of use and experience.
Based on this, relevant departments will test the touch screens of mobile phones before they are ready for production, the voice coil motor plays an important role in this test. The "soft landing" feature of the voice coil motor is used in the touch screen test, as it is quite helpful for the assembly of delicate or high-value parts. So how does the voice coil motor achieve a soft landing? Control the lower force near the surface in speed mode while continuously monitoring the position error. Once it reaches the surface, the position error increases to a pre-set value and the execution axis remains at that point on the surface.
