Description
Technical field
The utility model relates to the analog electrostatic field mapping technical field, the drive unit of the probe that is specifically related to use in the analog electrostatic field mapping, particularly probe.
Background technology
Because directly describing electrostatic field has difficulties, and the distribution of the distribution of steady current field and electrostatic field can be expressed with identical mathematical formulae, so come analog electrostatic field with the steady current field usually, the equipotential line of surveying and drawing various electric fields by the current potential between the potential electrode, and then analyze the distribution situation of electrostatic field.Therefore, analog electrostatic field mapping is the Physical Experiment that domestic and international institution of higher learning generally offer.
In analog electrostatic field mapping, the main cause of influence mapping degree of accuracy comprises: the precision of mapped point position in the quantity of measurement equipotential line and the definite electric field.
The experimental provision of present analog electrostatic field mapping all is the experimental provision of manual driven probe, as shown in Figure 2, experimental provision comprise conductive paper 10, electrode 12, probe 11, recording chart 13, with the recording pointer 14 of probe interlock, voltage table 15 etc.; Electrode is pressed on the conductive paper, and probe is connected with voltage table, and recording chart is placed on the below of recording pointer.During mapping, load steady voltage on electrode, the manual driven probe slides on the conductive paper between two electrodes, and with the current potential on the each point on the conductive paper between the potential electrode, recording pointer is measured the position of each point at the recording chart record.
There is following defective in the experimental provision of manual driven probe: 1, the manual driven probe slides on conductive paper, can't realize the potential measurement of big density, and the quantity of measuring equipotential line is few; 2, determine the low precision of probe position in electric field; 3, the control probe is in the low precision of certain some position in the electric field.Therefore, existing manual driven probe experimental provision mapping degree of accuracy is poor.
Summary of the invention
Technical problem to be solved in the utility model is: the drive unit of a kind of analog electrostatic field mapping with probe is provided, and this drive unit can be accurately for the probe location, for the potential measurement that realizes big density creates conditions.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
The analog electrostatic field mapping drive unit of probe, it comprises base, base is provided with X axis guided way, the platform that moves, is used to drive the stepper motor of platform on the X axis guided way; Platform is provided with the slide block that Y-axis moves on guided way to guided way, in Y-axis, the stepper motor that is used to drive slide block; Probe is arranged on the slide block.
In the such scheme, drive unit also comprises a connecting rod, and an end of connecting rod is connected with slide block, and the other end is provided with the probe connector, and probe is fixed on the slide block by connector, connecting rod.
The stepper motor of above-mentioned drive unit can be by Single-chip Controlling.
Drive probe with the utility model drive unit and compare, have the following advantages with existing manual driven probe:
1, the utility model drive unit driving probe slides on conductive paper, and its control accuracy can reach the 0.1mm/ step, can realize the potential measurement of big density fully, and the quantity of measuring equipotential line can increase greatly;
2, the Single-chip Controlling stepper motor can be passed through, the position that probe need arrive can be accurately set;
3, probe is in the electric field certain some position coordinates and also can be accurately detected automatically by single-chip microcomputer;
4, can on single-chip microcomputer, set, slide with control probe autoscan on conductive paper.
