Description

The silica optical fiber microprobe that is used for three-dimensional micro-force measurement
Technical field
The invention belongs to little power technical field of measurement and test, particularly a kind of silica optical fiber microprobe that is used for three-dimensional micro-force measurement.
Background technology
In recent years, along with the continuous development of MEMS (MEMS) technology, more and more scholars and research institution began microcosmos is furtherd investigate.Utilizing MEMS probe-type feeler that little power is monitored, is a kind of effective scientific method of understanding microcosmos in depth.MEMS Micro-force sensor probe mainly is divided into two kinds at present: 1. the silicon microprobe that utilizes the processing of MEMS technology: this probe integral body is a feeler lever, does not pop one's head in, and measure error is relatively large; Because silicon materials plasticity is poor, and probe diameter is very little, therefore in order to guarantee the normal use of probe, probe is done very shortly, and environment for use is restricted.2. metal probe: this probe is made up of metal feeler lever and ruby probe, has rigidity preferably.Ruby probe anti-wear performance is good, but the difficult processing that costs an arm and a leg is poor with metal feeler lever cement properties, and easily loosening, the life-span is short.The metal feeler lever is subject to magnetic interference, and a little less than the antijamming capability, error is bigger.
Summary of the invention
Problem at present prior art exists the purpose of this invention is to provide a kind of staged silica optical fiber microprobe that precision height, cost are low, processing is simple, the life-span is long, antijamming capability is strong that is used for three-dimensional micro-force measurement.
To achieve these goals, the technical solution used in the present invention is as follows:
The silica optical fiber microprobe that is used for three-dimensional micro-force measurement, by probe base 1, feeler lever 3 with pop one's head in and 4 form, probe base 1 is made by lucite, probe base 1 is the cylinder of a band blind hole 2, feeler lever 3 be a bottom big, by the cylindrical staged silica fibre structure that the bottom up diminishes successively, feeler lever 3 bottoms closely cooperate for 2 one-tenth with probe base blind hole; The top of feeler lever 3 disposes probe 4, and probe 4 is formed by the silica fibre fibre core drawing on feeler lever 3 tops.
The probe rapidoprint is a silica fibre, and the cylinder diameter of probe base 1 is 1.6mm, and height is 1mm.
Blind hole 2 diameters are 0.9mm, dark 0.8mm.
Feeler lever 3 bottom diameters are 0.9mm.
Probe 4 is less than or equal to the quartz ball of 40 μ m for diameter.
Probe 4 is that the silica fibre fibre core of 125 μ m draws and to form by feeler lever 3 top end diameter.
The cylindrical staged silica fibre structure of feeler lever 3 is three joints, and its diameter is followed successively by 900 μ m, 250 μ m, 125 μ m.
Because the probe 8 that machines will be installed on the sensor sensing unit,, therefore, adopt proportion little, the lucite processing probe base 1 that intensity is big for the interference of the own wt that reduces probe 8 to sensor; Lucite is a kind of macromolecule transparent material, and its chemical name is polymethyl methacrylate, and English is called for short PMMA, formed by methyl methacrylate polymerization, have smooth surface, the transparency is good, proportion is little, intensity is bigger, and is corrosion-resistant, moisture-proof, sun-proof, good insulation preformance, sound insulation property is good, anti-interference advantage such as strong.Can be when sensor package by the fixed installation situation of the transparent real-time monitoring probe of lucite base.Base is by the laser engraving machined, the finished product accuracy height.
The feeler lever of probe is in when design, and two factors limit mutually: for guaranteeing by dynamometry must to improve the rigidity of probe by complete being delivered on the sensor sensing element of probe, reduce the distortion of feeler lever; But improve the measurement sensitivity of sensor and the accurate operation under minute yardstick, increase the length of feeler lever and the yardstick that reduces to pop one's head in, the result has reduced the rigidity of probe.Therefore in the feeler lever design, must take all factors into consideration this two kinds of constraints, optimize the relevant parameter of feeler lever.
In order to improve the antijamming capability of probe, increase the length of probe, utilize silica fibre processed sensor feeler lever 3.Silica fibre has good optics and mechanical performance: optical fiber is glass fibre, and proportion is little, makes it have little, the lightweight characteristics of diameter, installs very convenient; Antijamming capability is strong, because the basis of optical fiber is quartzy, only passes light, and is non-conductive, is not subjected to the effect of electromagnetic field, and electromagnetic interference, industry disturbance are had very strong defensive ability/resistance ability; Because it is very abundant to make material (quartz) source of optical fiber, the optical fiber cost is low; Good corrosion resistance, the material (quartz) of making optical fiber is difficult for being corroded by the acid-base material in the industry.
Spherical probe 4 has reduced the damage to measured object, has improved certainty of measurement.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is elaborated.
As Fig. 1, shown in 2, probe 8 of the present invention is by probe base 1, feeler lever 3 and pop one's head in and 4 form, and probe base 1 is made by lucite, and probe base 1 is the cylinder of a band blind hole 2, blind hole 2 diameters are 0.9mm, dark 0.8mm, feeler lever 3 be a bottom big, by the cylindrical staged silica fibre structure that the bottom up diminishes successively, feeler lever 3 bottom diameters are 0.9mm, because the silica fibre skin has certain elasticity, so feeler lever 3 bottoms can closely cooperate with probe base blind hole 2; The feeler lever 3 that the bottom is scribbled epoxy resin is assembled in the blind hole 2, and dries one hour under 60 ℃ of environment, makes the probe 8 among its fixing Fig. 3 of formation; Probe 4 is less than or equal to the quartz ball of 40 μ m for diameter, is that the silica fibre fibre core drawing of 125 μ m forms by feeler lever 3 top end diameter.
As shown in Figure 3, probe 8 is installed on the sensor sensing component platform 7 in conjunction with pasting method based on the laser positioning method, extraneous tested masterpiece is used on the probe 4, be delivered on the sensor sensing component platform 7 through probe 8, make sensing element cantilever beam 6 produce distortion, cause that the piezo-resistance on the cantilever beam 6 changes, output voltage records active force.
