Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] refer to figure 1 , the present invention provides a glass surface defect detection system, including a carrying platform 1, a deep ultraviolet light source 2 and a special camera 3, wherein the carrying platform 1 is used to support and place the glass 10 to be detected; the deep ultraviolet light source 2 emits deep ultraviolet light and The glass 10 to be inspected on the carrying platform 1 is irradiated obliquely; the special camera 3 is installed directly above the carrying platform 1 and facing the surface of the carrying platform 1 for image acquisition.

[0028] The brightness of the deep ultraviolet light source 2 is adjustable, and the emitted deep ultraviolet light has a wavelength of 200nm-400nm.

[0029] The special camera 3 includes a camera sensor, and the front end of the camera sensor is provided with an optical filter...

Abstract

The invention discloses a glass surface defect detection system and method. The detection system comprises a supporting table, a deep ultraviolet light source, and a dedicated camera, wherein the supporting table is used for supporting the glass to be inspected. The deep ultraviolet light source emits an ultraviolet light and obliquely illuminates the glass to be inspected on the supporting table.The dedicated camera is installed right above the supporting table and faces the surface of the supporting table, and is used for collecting the reflected deep ultraviolet light. The detection methodusing the above detection system comprises four steps: placing the glass to be inspected; irradiating the deep ultraviolet light; acquiring an image; and determining whether there is a defect on theglass to be inspected. The detection system and method provided by the invention can solve the shortages that a visible light source for detecting glass defects in the prior art can generate a large background interference, by using the deep ultraviolet light source to detect, the background interference can be eliminated, and the accuracy rate is effectively improved.

Description

technical field [0001] The invention relates to the field of glass production and manufacturing, in particular to a glass surface defect detection system and method. Background technique [0002] Glass is an amorphous solid with complete long-range disorder in structure and transformation characteristics in performance. Calcium carbonate is added to ordinary glass during manufacture, so the light transmittance in the ultraviolet band is weakened, especially the light with a wavelength below 300nm is completely impermeable. [0003] With the continuous development of society and the continuous progress of science and technology, glass is more and more widely used in various fields, such as mobile phone screen films, laser resonators, camera lenses, electronic product displays, eyeglass lenses, and satellite optical lenses. With the development of science and technology, the demand and requirements for glass will further increase. However, in the glass production process, du...
