Glass has gradually become a key functional material in emerging fields. While glass is developing rapidly, people's requirements for the quality of glass are also getting higher and higher.

[0003] After glass is processed and formed, its surface quality usually needs to be inspected.

[0021] The basic working principle of the glass detection device based on the area array camera involved in the present invention is as follows: Figure 2 As shown, by arranging the first camera group and the second camera group on the fixing frame 301, when the conveying mechanism 1 is conveying the glass, the detection camera 201 located above the conveying mechanism 1 can photograph all the right-angled sides of the glass, and then according to the coordinate transformation of each detection camera 201 in the first camera group and the second camera group, the outer dimensions of the glass can be accurately converted, and through the coordinated work of the first camera group and the second camera group, only m detection cameras 201 are respectively arranged in the first camera group and the second camera group to form a surface array camera, so that m-1 pieces of glass can be detected at the same time; when the outer dimension detection is completed, when the conveying mechanism 1 continues to convey the glass, the detection camera 201 also It is capable of extracting images of the glass passing below in real time and continuously, and after stitching the image feature points, it is capable of obtaining complete visual image information of the glass, and further capable of accurately judging the surface quality of the glass, such as whether the glass has missing edges or corners, whether there are defects or scratches on the glass, whether there are white pen marks or ink dot marks on the glass, and other quality information; the area array inspection camera 201 composed of the first camera group and the second camera group greatly improves the inspection accuracy, and can accurately and comprehensively inspect the outer dimensions and surface quality of the glass, and avoid misjudging unqualified glass as qualified glass, which is of great significance for strictly controlling the glass quality and optimizing the glass production process.

[0022] See also Figures 1 to 3 The present invention is further described below with a specific embodiment:

[0023] In this embodiment, see Figure 1 and Figure 2 As a preferred design, the fixed seat mechanism 3 also includes a telescopic adjustment rod 304, one end of the telescopic adjustment rod 304 is fixedly connected to the first support rod 302, and the other end is fixedly connected to the second support rod 303. By setting the telescopic adjustment rod 304, the distance between the first support rod 302 and the second support rod 303 can be flexibly adjusted, that is, the first camera group can be flexibly adjusted to be close to or away from the second camera group, thereby expanding or reducing the area of ​​the detection station, so that the detection mechanism 2 can be suitable for glass detection of different specifications, thereby improving the practicality and applicability of the detection mechanism 2.

[0024] In this embodiment, see Figure 1 As a preferred design, the fixed seat mechanism 3 also includes a first fixed rod 305 and a second fixed rod 306, one end of the first fixed rod 305 is fixedly connected to the first support rod 302, and the other end is fixedly connected to the telescopic adjustment rod 304, one end of the second fixed rod 306 is fixedly connected to the second support rod 303, and the other end is fixedly connected to the telescopic adjustment rod 304. By setting the first fixed rod 305 and the second fixed rod 306, the stability of the fixed frame 301 mechanism can be improved, and vibration of the fixed frame 301 during the detection process can be avoided, thereby improving the accuracy of glass detection.

[0025] In this embodiment, see Figure 1 and Figure 3As a preferred design, the conveying mechanism 1 includes a support frame group, a roller group, a driving component and a support leg group. The support frame group includes two support frames, the roller group includes a plurality of rollers, the support leg group includes a plurality of support legs, the two ends of the rollers are respectively arranged on the two support frames, and the bottom of the support frame is provided with support legs. The driving component can drive the rollers to rotate along their own axes. The detection mechanism 2 is electrically connected to the driving component. The glass is placed on the roller group. The driving component drives the rollers to rotate along their own axes, so that the conveying mechanism 1 can convey the glass. When the glass is conveyed to the detection station, the detection camera 201 in the detection mechanism 2 detects the glass, and the detection mechanism 2 can send a signal to the driving component. A stop signal is sent to cause the driving component to temporarily stop driving the roller to rotate along its own axis. At this time, the first camera group and the second camera group will shoot the glass on the inspection station to ensure the accuracy of the glass dimensions extracted by the inspection mechanism 2. After the inspection mechanism 2 extracts the glass dimensions, the inspection mechanism 2 can send an open signal to the driving component to allow the driving component to continue to drive the roller to rotate along its own axis, so that the glass continues to move forward. While the glass continues to move forward, the inspection camera 201 extracts the image of the glass passing below in real time and uninterruptedly, thereby obtaining complete visual image information of the glass, and then accurately judging the surface quality of the glass.

[0026] As described above, the glass detection device based on the area array camera according to the present invention has the following beneficial effects:

[0027] By setting up the detection mechanism 2, the detection cameras 201 of the first camera group and the second camera group form an area array camera, which can coordinate work under the same system, and interact with data information in real time, so as to achieve accurate detection of the outer dimensions of the glass, and to obtain complete visual image information of the glass, and then accurately detect the surface quality of the glass, thereby avoiding misjudging unqualified glass as qualified glass.
