Referring to fig. 1, an embodiment of the present invention provides a wire diameter measuring device 10. The wire diameter measuring device 10 can be used for measuring the diameter of the measured wire 20 and has good adaptability and reliability.
In the embodiment of the present invention, the line diameter measuring device 10 includes a laser 11, a diaphragm 12, a first lens 13, a second lens 14, an image sensor 15 and a cylindrical mirror 16, the laser 11, the diaphragm 12, the first lens 13, the second lens 14 and the image sensor 15 are sequentially disposed, the laser 11 is used for emitting laser, and the cylindrical mirror 16 is disposed at any position between the diaphragm 12 and the image sensor 15, so that the laser passes through the cylindrical mirror 16 and then emits to the image sensor 15; the first lens 13 and the second lens 14 are used for placing the tested cable 20.
It should be noted that, in the embodiment of the present invention, a wire diameter measuring device 10 is provided; in addition to the above components, the wire diameter measuring device 10 may further include a housing, a screw, and other components for connection, and the embodiment of the present invention is not particularly limited to other components. The embodiment of the utility model provides an in, this line footpath measuring device 10 can make line footpath measuring device 10's angle allowance improve at double to promote line footpath measuring device 10's adaptability, guarantee measuring result's reliability.
In the embodiment of the present invention, the laser 11 emits laser, and the laser becomes parallel laser under the collimation effect of the first lens 13; the parallel laser passes through the cable 20 to be measured, and under the action of the second lens 14, the image sensor 15 can obtain the diffraction waveform of the cable 20 to be measured, namely an image of the cable 20 to be measured; the diffraction waveform is perpendicular to the measured cable 20, and the diameter of the measured cable 20 can be measured by analyzing the diffraction waveform obtained on the image sensor 15. In the embodiment of the present invention, the light transmission width of the diaphragm 12 and the parameters of the cylindrical mirror 16 are commonly used to adjust or control the width of the diffraction waveform, so that the diffraction waveform can be conveniently adjusted or controlled.
It should be noted that accuracy and adaptability are two important indexes for evaluating the performance of the measuring instrument. In the prior art, a cable measuring instrument based on the Fraunhofer diffraction principle has high measuring accuracy but poor adaptability. In the prior art, if the measured cable 20 is deflected in the Y direction, the diffraction image on the sensor is deflected accordingly, so that the photosensitive area on the sensor cannot receive the correct diffraction image, and the measuring instrument cannot measure the correct diameter of the cable. To ensure that the correct diffraction image is obtained on the sensor, it should be ensured that the diffraction image of the sensor coincides as much as possible with the photosensitive area of the sensor. The width of the photosensitive area of the existing high-precision line image sensor 1 is about 6-200um (um, length unit: micrometer), and the effective width of the diffraction image is about 100um, that is, after the diffraction image is deflected, the rotation offset of the diffraction image is 0.2mm/(L/2) (L is the length of the line image sensor, and mm is the length unit: millimeter). If L is 30mm, the offset angle is about 0.8 °, i.e. the angle adaptation margin of the existing measuring instrument is only 0.8 °, which causes great difficulty in cable installation in cable production.
In the embodiment of the present invention, the cylindrical mirror 16 is disposed between the diaphragm 12 and the image sensor 15, and can adjust or control the light received by the image sensor 15. In the embodiment of the present invention, both the diaphragm 12 and the cylindrical mirror 16 can adjust the light transmission width; the diffraction image received on the image sensor 15 changes, the diffraction waveform becomes wider in the Y direction, and the width of the diffraction waveform in the Y direction is determined by the light transmission width of the diaphragm 12 and the parameters of the cylindrical mirror 16, so that the width of the diffraction waveform can be adjusted more conveniently. In the embodiment of the present invention, if the width of the diffraction waveform is increased to 1.5mm, the angle margin of the line diameter measuring device 10 becomes 1.5/(L/2), and if L is 30mm, the angle margin becomes 5.6 °, which is 7 times of 0.8 ° in the prior art. In this case, as long as the inclination angle of the cable 20 to be measured does not exceed 5.6 °, the measuring instrument can obtain a correct measurement result, which greatly facilitates the installation and debugging of the measuring instrument and improves the reliability of long-term use.
Meanwhile, in the cable industry, cables with the wire diameter of 0.005-0.200 mm are called microwires, and instruments for measuring the diameters of the metal wires are called microwire measuring instruments. At present, the microwire diameter is mainly measured by a measuring instrument based on the fraunhofer diffraction principle. However, in the prior art, the measuring instrument has poor adaptability to the microwire. In the embodiment of the present invention, the light transmission width can be adjusted by both the diaphragm 12 and the cylindrical mirror 16; the diffraction image received on the image sensor 15 changes, the diffraction waveform becomes wider in the Y direction, and the width of the diffraction waveform in the Y direction is determined by the light transmission width of the diaphragm 12 and the parameters of the cylindrical mirror 16, so that the width of the diffraction waveform can be adjusted more conveniently. That is to say, the embodiment of the utility model provides a can also be better to the measurement adaptability of microwire, be favorable to guaranteeing the measurement accuracy of microwire. It should be understood that the embodiment of the present invention provides a wire diameter measuring device 10 that basically does not require the diameter of the measured wire 20, i.e. in theory, any size of wire can be measured.
In addition, it should also be noted that the cable measuring device 10 provided by the embodiment of the present invention may be used for measuring the wire diameter of a cable, and the cable may include not only common cables, electric wires, wire cores, etc., but also other arbitrary linear structures; that is, embodiments of the present invention may be used for any diameter of a linear or strip-shaped object.
