Description
Technical field
The present invention relates to field of measuring technique, especially relate to a kind of measurement mechanism to siliconized plate thickness.
Background technology
Siliconized plate is a kind of ferro-silicium of silicon content 0.5%～4.8%.It is a kind of soft magnetic material being widely used at electrical field, is mainly used in motor, generator, transformer, electromagnetic mechanism, relay electron device and measurement instrument.Electrician is conventionally rolled into standard-sized large sheet material with siliconized plate or band is used.The thickness evenness of siliconized plate is a very important quality characteristic.If siliconized plate central authorities are too large with the difference in thickness at edge, or the variation of the thickness of siliconized plate length direction is too large, all can have influence on the thickness unshakable in one's determination after assembling.Different thickness unshakable in one's determination, its permeance variation is also large, directly has influence on the characteristic of motor, generator, transformer, and therefore the thickness to siliconized plate production and in using detects particularly important.
The thickness detecting method of thin steel sheet is generally divided into two kinds of contact type measurement and non-contact measurements.Because contact measuring thickness device can cause certain damage to sheet material, therefore be applicable to off-line measurement, on-line measurement generally adopts non-contact measurement.Utilizing laser-CCD thickness measuring is conventional contactless measurement.Chinese patent application publication No. CN103063151A, on April 24 2013 Shen Qing Publication day, name is called the patent of invention of " a kind of thickness measurement with laser C type frame mechanism and adjustment using method ", discloses a kind of thickness measurement with laser C type frame machine structure.A kind of thickness measurement with laser C type frame mechanism, it also comprises that platform group is moved at angle, inferior horn moves platform group, bottom offset platform group to comprise C type frame housing, upper laser sensor, lower laser sensor, upper laser sensor moves platform group by upper angle and is connected to C type frame housing top, lower laser sensor by inferior horn move platform group, bottom offset platform group is connected to C type frame lower housing portion; Upper angle is moved platform group, inferior horn and is moved platform group and by two, adjust the orthogonal angles of direction respectively and move platform and form, and bottom offset platform group is adjusted the orthogonal displacement platforms of direction by two and formed.Upper-lower position by the laser sensor in two image data of C shape frame front end has been installed special adjusting gear, and utilize the light can this physical features of display beams path in suspension, laser sensor is being adjusted, and upper and lower two detected data of laser sensor are in static, the dynamically lower optimum measurement accuracy requirement that can both reach this sensor thus.This structure need to be settled at C shape frame front end the laser sensor of two image data, during calibration accuracy requirement higher, because too accurate self the vibration of equipment also can have a strong impact on laser instrument measurement result, therefore be not suitable for the application of factory's online production.
For the siliconized plate for high-power transformer, siliconized plate width is controlled at 40cm in producing.Its thickness is more even, generally there will not be and sharply increases phenomenon, but there will be the steady conversion in certain limit, and because process for surface coating is superior, siliconized plate surface reflection is better, can use up reflection class methods test thickness.Chinese patent Granted publication CN202485637U, on October 10 2012 Granted publication day, name is called the utility model patent of " the online dynamically non-contact laser thickness measuring system of a kind of sheet material ", discloses the online dynamically noncontact thickness measuring structure of a kind of sheet material.It comprises several laser feelers of one of them the roller top that is positioned at plate-extruding machine output terminal, laser feeler vertical irradiation is in the top of roller bus, several laser feelers are all connected with an industrial control host, and the output terminal of industrial control host is connected sheet material with one with acoustic-optic alarm respectively with the plate-extruding machine actuating unit that roller departs from.This utility model is provided with several laser feelers above one of them roller of plate-extruding machine output terminal, laser feeler is connected with industrial control host, operator can arrange the thickness upper lower limit value of product in industrial control host, when thickness transfinites, can send sound and light alarm.This structure has the thickness of several laser head sheet material measurements above roller, does not in fact need, because a plurality of laser instrument is just guaranteed the accuracy of final measured value.If when final measurement surpasses certain value, need to stop carrying sheet material, process.The sheet material of this structure can not guarantee to be adjacent to roller completely and there is no space in addition, has increased introducing error term, and the confidence level of measurement is lower.
