Contact-type displacement sensor structure based on 3D printing and making method thereof

Abstract

The invention discloses a contact-type displacement sensor structure based on 3D printing and a making method thereof. The contact-type displacement sensor structure comprises a base structure; one end of the base structure is provided with a second fixing hole and the other end is provided with a guide hole; a cantilever structure is connected above the base structure; the second fixing hole in the base structure is flush with a first fixing hole at the tail end of the cantilever structure; the tail end of the cantilever structure is provided with a strain gauge structure; the head end of thecantilever structure is provided with a limiting hole; a probe passes through the guide hole in the base structure; and the upper end of the probe is located in the limiting hole and the lower end isused for contact measurement. The making method adopts a combination of a photocuring process and an ink-jet printing process, conductive ink is directly sprayed on the resin cantilever structure, and aking of a three-dimensional composite structure sensor is realized; a desktop photocuring printer is used to make the sensor structure; and the contact-type displacement sensor structure based on 3D printing and the making method thereof have the advantages that the processing cost is low, the processing cycle is short, the production is simple and the structure is optimized and convenient andthe like.

Description
