Abstract

The invention provides a feasibility verification device and method applicable to a displacement sensor. The displacement sensor comprises a body and a magnetic strip. The feasibility verification device comprises a bracket, wherein the bracket is provided with a guide rail; a fixing piece arranged on the guide rail moves along the guide rail and is used for bearing a lens; a motor is used for driving the fixing piece to move along the guide rail; an angle adjusting piece is arranged on the fixing piece and provided with an extension part in the direction of the guide rail; the extension partis suitable for bearing the magnetic strip; at least two connectors are used for connecting the angle adjusting piece and the fixing piece at different positions; at least two distance adjusting pieces are used for adjusting the distance between the angle adjusting piece and the fixing piece at different positions. A rangefinder is used for detecting the distance between a rangefinder body and themagnetic strip. The device has the advantages of being simple in structure, reliable in verification result and the like.

Description

technical field [0001] The invention relates to a displacement sensor, in particular to a feasibility verification device and method for the application of the displacement sensor. Background technique [0002] With the development of photographic element technology, people have higher and higher requirements for the precision and speed of automatic zooming of the lens, so there are higher requirements for the driving device of the lens, and high-precision displacement is often used in the way of improving the precision sensor. [0003] The application of high-precision displacement sensors for lenses is usually more complicated, and there is a large gap between the mechanical structure accuracy tolerance of the sensor and the required installation accuracy, so the detection device needs to have higher installation accuracy and adjustability, and at the same time Certain detection components can be replaced. [0004] Because the mold opening of the plastic lens barrel is e...
