Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of glass processing, in particular to a detection device. Background Art
[0002] Float glass is widely used and is divided into tinted glass, float silver mirror, float glass / automobile windshield grade, float glass / various deep processing grades, float glass / scanner grade, float glass / coating grade, float glass / mirror grade. Among them, ultra-clear float glass has a wide range of uses and broad market prospects. It is mainly used in high-end buildings, high-end glass processing and solar photovoltaic curtain walls, as well as high-end glass furniture, decorative glass, imitation crystal products, lamp glass, precision electronics industry and special buildings.
[0003] Float glass is formed by floating molten glass on liquid metal tin. During the forming process, the molten glass is spread out, thinned, and cooled to form a semi-liquid state at 1150°C, dropping to a solid state at 610°C. During this period, local deformation may occur due to equipment reasons in the tin bath or manufacturing process reasons. This is the deformation line. This deformation is different from bubbles and stones in conventional glass. Bubbles and stones refract light, causing light distortion around them, which can be easily automatically identified by scanners, while deformation lines have no light distortion. Existing online detection equipment has poor detection accuracy and a high misjudgment rate when detecting defects such as deformation lines. Utility Model Content

[0034] During the glass forming process, the molten glass is spread out, thinned, cooled and formed, and its temperature drops from a semi-liquid state at 1150°C to a solid state at 610°C. During this period, local deformation may occur due to equipment reasons in the tin bath or manufacturing process reasons, which is the deformation line. This deformation is different from bubbles and stones in conventional glass. Bubbles and stones refract light, causing light distortion around them, which can be easily automatically identified by scanners. Deformation lines have no light distortion. Existing online detection equipment has poor detection accuracy and a high misjudgment rate when detecting defects such as deformation lines.
[0035] The utility model provides a detection device.
[0036] See also Figure 1 and Figure 2 In one embodiment of the present utility model, the detection device 100 comprises:
[0037] A base frame assembly 1 forms a detection space inside;
[0038] A conveying assembly 2 is disposed in the detection space and is used to convey the glass plate 21;
[0039] A reflective structure 3 is disposed on the base frame and is located below the conveying assembly 2; and
[0040] The light source assembly 4 includes a core light source 41 and a stripe light source 42. The core light source 41 is disposed on the base frame and is located above the conveying assembly 2. The stripe light source 42 is disposed on the base frame and is located below the conveying assembly 2.
[0041] The light from the core light source 41 passes through the glass plate 21 and the stripe light source 42 in sequence, and then projects the image of the glass plate 21 onto the reflective structure 3 , and then is reflected by the reflective structure 3 and presented to the user.
[0042] In the technical solution of the present invention, a detection space is formed inside the base frame assembly 1. When the glass plate 21 needs to be inspected after processing, the glass plate 21 to be inspected can be transported to the detection space through the conveying assembly 2. In order to inspect the glass plate 21, the light source assembly 4 in the scheme includes a core light source 41 and a stripe light source 42, wherein the core light source 41 is arranged on the base frame and located above the conveying assembly 2, and the stripe light source 42 is arranged on the base frame and located below the conveying assembly 2, so that the light of the core light source 41 successively penetrates the glass plate 21 and the stripe light source 42, and then transmits the image of the glass plate 21 to the reflective structure 3 below the conveying assembly 2, and is reflected by the reflective structure 3 and presented to the user. The user identifies whether there are defects based on the image. After the inspection is completed, the glass plate 21 is output from the inspection space through the conveying assembly 2, and the quality inspection of the glass plate 21 can be completed. In this solution, the core light source 41 provides high-intensity light to illuminate the glass plate 21, and the stripe light source 42 can provide contrast. The cooperation of the stripe light source 42 and the core light source 41 can provide sufficient light intensity and contrast for image detection, making the image reflected by the reflective structure 3 more prominent, which is more conducive to the user to clearly identify defects such as lines and deformations on the glass plate 21, thereby improving the accuracy of detection.
[0043] Specifically, in this embodiment, the stripe shape on the stripe light source 42 is not specifically limited, as long as it can play a role in magnifying the angle of optical deformation on the glass plate 21, which is conducive to the user to observe the deformation line and other defects more clearly. In addition, in addition to providing black and white light with a certain contrast, the stripe light source 42 must also have a certain light transmittance to facilitate the light source emitted by the core light source 41 to pass through. It should be noted that there is no specific limitation on the setting angle and size of the reflective structure 3, as long as it can meet the light source component 4 to project the image of the glass plate 21 into the reflective structure 3. This detection scheme is not only easy to operate and has high detection efficiency, but also can effectively solve the problem of line detection in float glass production, greatly reduce manual labor intensity, reduce labor costs, and at the same time ensure the stability and reliability of product quality, meet the real-time requirements of float glass online detection lines and the market demand for high-quality glass products.
