Abstract

The utility model relates to the technical field of photoelectric detection, and especially relates to an edge curved angle contour detection apparatus of flat glass. The apparatus comprises a workbench surface for the flat glass to place, an image capturing device and multiple light sources spaced at the same intervals on the same plane. The image capturing device is arranged at the transmitting line of the edge curved angle contour of the flat glass for reflection of the light sources, such that the image capturing device obtains a shadow image on the edge curved angle contour of the detected flat glass and transmits the obtained shadow image to a computer for analysis processing. According to the utility model, a photoelectric instrument is employed, corresponding parameters in a plane image is measured, and then through comparing the parameters, whether a curved angle accords with a processing requirement is determined. The detection apparatus has the advantages of simple structure, easy production and implementation, high detection precision, fast speed, promoted production process and guaranteed terminal product quality.

Description

The edge inverted arc corner contours pick-up unit of sheet glass
Technical field
The utility model relates to photoelectric detection technology field, especially relates to the edge inverted arc corner contours pick-up unit of sheet glass.
Background technology
It is mainly to rely on artificial vision to detect that the edge inverted arc corner contours of traditional sheet glass detects, and precision is not high, and error is large; Have subsequently the numerical value mode of measuring inverted arc angle by surveying instrument and detect, greatly improve accuracy of detection although this, efficiency is low, affects production process.
Summary of the invention
The purpose of this utility model is to overcome the defect of prior art, provides a kind of accuracy of detection high, and speed is fast, implements to be easy to the edge inverted arc corner contours pick-up unit of sheet glass.
For achieving the above object, the utility model adopts following technical scheme:
The edge inverted arc corner contours pick-up unit of sheet glass, this device comprises that work top, the image laid for sheet glass seize device and at grade multiple and equidistant light source, image is seized edge inverted arc corner contours that device is placed in sheet glass on the emission line of light source reflection, take this, image is seized device and is obtained the shadow image in the edge inverted arc corner contours of tested sheet glass, and image is seized device and sent the shadow image of acquisition to computer for analysis processing.
In such scheme, described multiple light sources are the many long fluorescent tubes that are arranged side by side.
In such scheme, described multiple light sources are the equidistantly mobile formation at grade of a long fluorescent tube.
The utility model adopts photoelectric instrument, by the relevant parameter in measurement plane image, relatively evaluate inverted arc angle with parameters obtained again and whether meet processing request, this structure of the detecting device is simple, easily produce, implement, accuracy of detection is high, and speed is fast, the quality that is conducive to promote production process and ensures end product.
brief description of the drawings:
Accompanying drawing 1 is principle schematic of the present utility model;
The image that accompanying drawing 2 is Fig. 1 embodiment is seized device and is obtained image schematic diagram.
embodiment:
Below in conjunction with accompanying drawing, the utility model is further illustrated:
Consult shown in Fig. 1,2, the utility model is about a kind of edge inverted arc corner contours pick-up unit of sheet glass, this device comprises that work top 5, the image laid for sheet glass 4 seize device 2 and at grade multiple and equidistant light source 1, image is seized edge inverted arc corner contours that device 2 is placed in sheet glass 4 on the emission line of light source reflection, take this, image is seized device 2 and is obtained the shadow image 3 in the edge inverted arc corner contours of tested sheet glass, and image is seized device 2 and sent the shadow image 3 of acquisition to computer for analysis processing.On computer display screen, measure the distance of adjacent Shadow to Light on shadow image, the distance finally comparing and measuring and standard value, whether evaluation inverted arc corner contours meets processing request.Seize transmission between device 2 and computer, be treated to routine techniques for image, do not repeat them here.
Detect principle: according to image related, it is proportional that distance L between multiple light sources 1 and image are seized the distance L 1 of the adjacent Shadow to Light in the shadow image 3 that device 2 obtains, for the inverted arc corner contours of setting, the distance L 1 that image is seized the adjacent Shadow to Light in the shadow image 3 that device 2 obtains is the proportional horizontal definite value of distance L between relatively multiple light sources 1, count standard value, at this moment, the actual measured value detecting and above-mentioned standard value are compared, can utilize difference to converse the curvature in tested inverted arc corner contours, be converted by computer.Certainly also can utilize comparing difference to evaluate inverted arc corner contours and whether meet processing request, as non-in the distance of measuring equidistant, and deviation exceeds allowed band, can evaluate inverted arc corner contours and not meet processing request.
In the utility model, described multiple light source 1 can be the many long fluorescent tubes that are arranged side by side, also can be a long fluorescent tube equidistant mobile formation at grade, as long as provide on the inverted arc angle, edge that equidistant light source is irradiated to tested sheet glass, so that the inverted arc angle, edge of sheet glass is detected.
The detection method precision that the utility model provides is high, and speed is fast, and technique is simple, the quality that is conducive to promote production process and ensures end product.
Certainly; in conjunction with embodiment, the utility model is described in detail above; be only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art understand content of the present utility model and implemented; can not limit protection domain of the present utility model with this; therefore the equivalence of doing according to the utility model Spirit Essence all changes or modifies, and all should be encompassed in protection domain of the present utility model.
