Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] Such as figure 1 , shown in 2, probe 8 of the present invention is made up of probe base 1, probe rod 3 and probe 4, and probe base 1 is made of plexiglass, and probe base 1 is a cylinder with blind hole 2, and blind hole 2 The diameter is 0.9mm, and the depth is 0.8mm. The probe rod 3 is a cylindrical stepped silica fiber structure with a large bottom end and gradually becomes smaller from the bottom end to the top. The diameter of the bottom end of the probe rod 3 is 0.9mm. The layer has a certain degree of elasticity, so the bottom end of the probe rod 3 can be closely matched with the blind hole 2 of the probe base; the probe rod 3 coated with epoxy resin at the bottom end is assembled into the blind hole 2, and dried at 60°C an hour to allow it to set image 3 The probe 8 in the figure; the probe 4 is a quartz ball with a diameter less than or equal to ...

Abstract

The invention provides a silica optical fiber microprobe for three-dimensional micro-force measurement. The microprobe consists of a probe base, a probe rod and a probe, wherein the probe base is made of organic glass and is a cylinder provided with a blind hole; the probe rod has a cylindrical stepped silica optical fiber structure which has a large bottom end and becomes smaller from the bottomend to the top; the bottom end of the probe rod is in close fit with the blind hole on the probe base; the top end of the probe rod is provided with the probe; and the probe is prepared by pulling a silica optical fiber core from the top end of the probe rod. The microprobe has the characteristics of high accuracy, low cost, simple processing, long service life and high anti-jamming capability.

Description

technical field [0001] The invention belongs to the technical field of micro-force testing, in particular to a quartz fiber micro-probe for three-dimensional micro-force measurement. Background technique [0002] In recent years, with the continuous development of microelectromechanical systems (MEMS) technology, more and more scholars and research institutions have begun to conduct in-depth research on the microcosm. Using MEMS probe-type contact sensors to monitor micro-forces is an effective scientific method for in-depth understanding of the microscopic world. At present, MEMS micro force sensor probes are mainly divided into two types: 1. Silicon micro probes processed by MEMS technology: this probe is a probe rod as a whole, without a probe, and the measurement error is relatively large; due to the poor plasticity of silicon materials, Moreover, the diameter of the probe is very small, so in order to ensure the normal use of the probe, the probe is made very short, an...
