Abstract
Description
Technical Field
[0001] This invention relates to the field of photosensitive material plate testing technology, and more specifically to a photosensitive material plate testing device and a photosensitive material plate testing method. Background Technology
[0002] A photosensitive material plate includes a substrate and a photosensitive liquid layer on the substrate.
[0003] The flatness of the photosensitive material sheet is crucial to its quality. During the production process, the photosensitive material sheet undergoes multiple bends, resulting in a certain degree of curvature, meaning its cross-section is arc-shaped. Therefore, the degree of curvature of the photosensitive material sheet must be inspected before packaging.
[0004] In the existing technology, the detection of photosensitive material plates is done by visual observation, that is, by manual observation, which has the disadvantage of inaccurate testing. Summary of the Invention
[0005] The purpose of this invention is to address the aforementioned shortcomings by providing a photosensitive material plate detection device and a photosensitive material plate detection method that offer more accurate detection capabilities.
[0006] The technical solution of the photosensitive material plate detection device of the present invention is implemented as follows: The photosensitive material plate detection device is characterized in that it includes a base with two parallel uprights on the base, and a vertically arranged detection plate installed between the two uprights. The detection plate is a transparent glass plate with a flat plate structure. There is also a clamp on the detection plate, which is a component for clamping the upper edge of the photosensitive material plate. The detection plate has a detection surface, which is the side that contacts the photosensitive material plate during detection. The side of the detection plate opposite to the detection surface is the detection face, which is the side away from the photosensitive material plate during detection.
[0007] Furthermore, the detection plate has multiple through-holes running horizontally, and these holes are evenly distributed across the plate.
[0008] Furthermore, the angle between the detection surface and the horizontal plane is 92-95°.
[0009] Furthermore, a long strip light is installed on the top and / or side of the detection plate. The strip light is set parallel to the detection surface and is connected to a power source via a switch.
[0010] The technical scheme of the present application is realized as follows: the method for detecting the photosensitive material plate is as follows: first, the photosensitive material plate is clamped on a vertically arranged detection plate, one side of the photosensitive material plate is close to the detection plate, and whether there is a gap between the one side of the photosensitive material plate and the detection plate is detected; then, the photosensitive material plate is turned over, the other side of the photosensitive material plate is close to the detection plate, and whether there is a gap between the other side of the photosensitive material plate and the detection plate is detected; if there is no gap in the two detections, it is proved that the photosensitive material plate is flat, and if there is a gap in any one detection, it is proved that the photosensitive material plate is not flat.
[0011] Further, in the detection process, the distance between the middle position of the photosensitive material plate and the detection plate is also tested, if the distance is within a certain range, it is determined that the photosensitive material plate is flat, and if the distance exceeds a certain range, it is determined that the photosensitive material plate is not flat.
[0012] The present application has the advantages that the photosensitive material plate detection device and the photosensitive material plate detection method have the advantages of accurate testing. BRIEF DESCRIPTION OF DRAWINGS

[0020] The clip is the part of the photosensitive material plate 5 on the edge of the detection plate, that is, the fixed part, the clip can use the book clip and other prior art, as long as the photosensitive material plate on the surface can be fixed.
[0021] When detecting the photosensitive material plate, one side of the photosensitive material plate is close to the detection surface of the detection plate, and the lower surface of the photosensitive material plate and the detection surface is observed to see if there is a gap, then the photosensitive material plate is turned over, and the other side of the photosensitive material plate is close to the detection surface. If the two detections are perfect, that is, there is no gap, it proves that the flatness of the photosensitive material plate is flat; if the value of the gap is less than a certain value, it proves that the flatness of the photosensitive material plate meets the requirements; if the value of the gap is greater than a certain value, it proves that the flatness of the photosensitive material plate does not meet the requirements.
[0022] The photosensitive material plate detection device of the present application is in a free state when detecting the photosensitive material plate, if the lower surface of the photosensitive material plate is outwardly curved, there is a gap between the lower surface of the photosensitive material plate and the detection plate, as shown in Figure 2 , which can be detected.
