Embodiment 1

[0034] figure 2 It shows a structural schematic diagram of an embodiment of the glass full-scale warping flatness detection device of the present invention, and is also a schematic diagram of a preferred embodiment. like figure 2 As shown, the glass full-scale warping flatness detection device described in this embodiment includes: a frame 10, a conveying module 20, a lighting module 30, an imaging module 40, a camera module 50, and an image processing module ( not shown in the figure), wherein, the frame 10 is used to carry the module set on it; the transport module 20 is set above the frame 10, and is used to transport the sample 60 to be tested; the The illumination module 30 is arranged under the frame 10, and is used to provide illumination for warpage flatness detection, and the light emitted by the illumination module is incident on the sample to be tested in the transport module; the imaging module Group 40 is arranged above the frame, and the light emitted by the ...

Embodiment 2

[0040] It is worth mentioning that this embodiment is optimized on the basis of the first embodiment, which can meet the detection requirements of higher standards. Therefore, the structure of each module described in the first embodiment is also applicable to the second embodiment. I won't repeat them here. Further, such as image 3 As shown, a reflector 70 is also provided above the frame 10 in this embodiment, and a uniform flat plate 80 is provided at the front end of the imaging module 40. The uniform flat plate 80 in this embodiment is preferably a white uniform flat plate. During detection, the light The light emitted by the module enters the reflector 70 after passing through the sample 60 to be tested, and is projected onto the uniform flat plate 80 after being reflected by the reflector 70. The image on the uniform flat plate is collected by the imaging element 50, and the collected image Send it to the image processing module to perform the calculation of the warpa...

Embodiment 3

[0043] This embodiment provides a method for detecting full-scale warping and flatness of glass, which includes the following steps:

[0044] Step A, place the sample to be tested at the front end of the conveying module, and the sample to be tested moves to the rear end of the conveying module under the drive of the conveying module; in this step, as described in Embodiment 2, the automatic feeding mechanism can be used to The sample to be tested is placed at the front end of the conveying module;

[0045] Step B. When the sample to be tested moves to the gap area of ​​the conveying module, the linear light emitted by the linear light source in the illumination module enters the sample to be tested after passing through the standard grid;

[0046] Step C, the linear light transmitted by the sample to be tested enters the imaging module for imaging;

[0047] Step D, the line array camera in the camera module collects continuous segmented images of the sample to be tested, and...

Abstract

The invention belongs to the field of optical detection, and particularly relates to a glass full-size warping evenness detection device and detection method. The glass full-size warping evenness detection device comprises a rack, a conveying module, an illumination module, an imaging module, a camera module and an imaging processing module, wherein when detection begins, a to-be-detected sample is only needed to be placed at the front end of the conveying module, so that full-size warping flatness detection can be carried out under driving of the conveying module; and in a detection process,participation of workers is not needed, so that a large quantity of manpower and material resources is reduced, the working efficiency is high, a quality project of wrapping unevenness in a glass production technological process can be monitored and detected in real time, the aim of inspecting the glass one by one is fulfilled, comprehensive detection can be carried out, missed detection is avoided, detection accuracy is high, output of defective products is reduced, quality and using performance of the to-be-detected sample are improved, manpower used in random inspection and a process in theexisting detection process can be greatly improved, and detection result data can be fed back in real time in a detection process, and production staffs and quality detection staffs can do effectiveand real-time disposal according to a feedback result, so that the working efficiency is improved.

Description

technical field [0001] The invention belongs to the field of optical detection, and in particular relates to a detection device and a detection method for glass full-scale warping flatness. Background technique [0002] Since 2005, the Chinese government has actively promoted the construction of the panel industry, ensuring the industrial layout of panel companies in terms of policies and funds. According to statistics, in 2016, the global LCD TV panel shipments reached 258 million pieces, and the shipment area reached 130 million square meters. From the perspective of the panel market share of various countries in the world, the shipments of panel manufacturers in mainland China accounted for 30% of the world, only Ranked second in the world after South Korea, surpassing Taiwan's 25.5% market share for the first time. With consumption upgrades and ultra-high-definition large-scale smart TVs, the global demand for large-size panels has been strong in recent years. The mark...
