Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in FIG. 1, the detection device of the present invention comprises a container 1 provided with a detection chamber 13 and an antireflection film 2 plated on the container 1, and quality detection of a cover plate 4 is performed by the container 1 and the antireflection film 2. The detected cover plate 4 may be made of glass, acrylic, or the like. The cover plate 4 may be planar or arc. At present, most of the cover plates 4 to be inspected are planar cover plates 4, and therefore the following embodiments take the inspection of the planar cover plates 4 as an example to describe in detail the configurations of the container 1 and the antireflection film 2.
The container 1 can be a glass container 1, that is, the bottom wall 11 and the side wall 12 of the container 1 are made of glass and can be integrally formed, the transparency of the glass is good, the cost is low, and when the glass container 1 is made to be thick, the quality can be ensured, and the quality influence on the plane cover plate 4 caused by the quality defect of the container 1 is reduced.
The detection chamber 13 is defined by the bottom wall 11 and the side wall 12 of the container 1, and the side wall 12 includes a transparent wall 121 in a transparent plane shape. The antireflection film 2 is plated on the outer side of the transparent wall 121. The detection chamber 13 is used for containing the liquid 3 and the planar cover plate 4. The liquid 3 may be, for example, water or the like, and is preferably water, which does not cause secondary damage to the flat cover 4, and is inexpensive, and when the material of the container 1 and the flat cover 4 is, for example, glass and the liquid is water, the refractive index of glass is 1.52%, the refractive index of water is about 1.33%, and the reflectance of the interface (the interface when light enters water from glass or enters glass from water) is substantially about 0.44%. When it is desired to test the quality of the flat cover 4, the liquid 3 is contained in the test chamber 13, the flat cover 4 is placed in the liquid 3 with the flat cover 4 facing the transparent wall 121 and with the liquid 3 separating the flat cover 4 and the transparent wall 121, and then the flat cover 4 is viewed from the outside of the container 1.
Since the outer side of the transparent wall 121 is plated with the antireflection film 2, the reflectivity of the outer side of the transparent wall 121 (i.e., the interface 1) is substantially about 0.4%, and when the inner side of the transparent wall 121 is filled with the liquid 3, such as water, the reflectivity of the inner side of the transparent wall 121 (i.e., the interface 2) is substantially about 0.44%, and the surface of the planar cover 4 is wrapped by the liquid 3, so that the reflectivity of the surface of the planar cover 4 (i.e., the interface 3) is substantially about 0.44%. Therefore, when the flat cover 4 is viewed from the outside of the container 1, the total reflectance of the surface of the flat cover 4 is substantially about 1.28%, which is much smaller than the reflectance of the flat cover 4 in air, i.e., about 4.2%. Therefore, before the antireflection film 2 is plated on the surface of the plane cover plate 4, the defects on the surface of the plane cover plate 4 can be well observed, the defective plane cover plate 4 is subjected to relevant recovery processing, the yield of the plane cover plate 4 after the antireflection film 2 is plated is improved, the loss of the plane cover plate 4 is reduced, and the cost is reduced.
Of course, when the container 1 and the flat cover 4 are made of other materials and the liquid is made of other materials, the total reflectance of the surface of the flat cover 4 does not substantially exceed 1.5% when the flat cover 4 is viewed from the outside of the container 1, and is much smaller than the reflectance of the flat cover 4 in the air, that is, about 4.2%.
The planar cover plate 4 may be fixed in the detection chamber 13 in various ways. In one example, as shown in fig. 2, the side wall 12 further includes a parallel wall 122 disposed parallel to and opposite to the transparent wall 121, and a first connection wall 123 and a second connection wall 124 connecting the transparent wall 121 and the parallel wall 122. And the width of the transparent wall 121 is greater than that of the parallel wall 122, the first and second connection walls 123 and 124 extend obliquely from the transparent wall 121 to the parallel wall 122. Further, the antireflection film 2 is plated on the outer side of the parallel wall 122, and the first connecting wall 123 and the second connecting wall 124 are transparent without plating the antireflection film 2. When the flat cover 4 is to be inspected, the flat cover 4 is placed into the inspection chamber 13 toward the transparent wall 121 or the parallel wall 122 according to the width of the flat cover 4, and then the flat cover 4 is moved toward the side of the parallel wall 122 until the flat cover 4 is caught between the first connecting wall 123 and the second connecting wall 124, so that the flat cover 4 is fixed in the inspection chamber 13.
By arranging the container 1 in the above way, quality detection can be performed on each part of the plane cover plate 4, particularly edges which are easy to generate defects, so that the influence on the quality of the plane cover plate 4 after the antireflection film 2 is plated on the plane cover plate is reduced because the part can not be detected; the parallel wall 122 is also plated with the antireflection film 2, and the quality detection can be carried out when the plane cover plate 4 faces the transparent wall 121 or the parallel wall 122, so that the detection efficiency is improved; when the first connecting wall 123 and the second connecting wall 124 are transparent, the light transmittance in the detection cavity 13 is improved, and whether the surface of the planar cover plate 4 has defects or not is conveniently observed.
In addition, the bottom of the first connecting wall 123 and the bottom of the second connecting wall 124 are provided with a ledge 125. When the plane cover plate 4 is placed into the detection cavity 13, the convex edge 125 supports the plane cover plate 4, so that the plane cover plate 4 is stably fixed in the detection cavity 13, and the risk that the plane cover plate 4 collides with the container 1 to be damaged is reduced. A gap is reserved between the convex edge 125 and the bottom wall 11, when the flat cover plate 4 is placed on the convex edge 125, a certain gap is reserved between the flat cover plate 4 and the bottom wall 11 of the container 1, the bottom of the flat cover plate 4 is filled with liquid 3 with a certain height, the flat cover plate 4 and the bottom wall 11 of the container 1 are separated by the liquid 3, and the interference of the bottom wall 11 of the container 1 on the flat cover plate 4 is reduced.
Further, the antireflection film 2 extends to the upper surface of the convex edge 125, i.e. in the direction perpendicular to the bottom wall 11 of the container 1, and the gap between the antireflection film 2 and the convex edge 125 is substantially zero, so that when the mass of the flat cover plate 4 is detected, the interference of the convex edge 125 with the mass of the flat cover plate 4 is reduced. The protruding edge 125 may also be made of glass, and the protruding edge 125 disposed on the first connecting wall 123 and the first connecting wall 123 are integrally formed, and the protruding edge 125 disposed on the second connecting wall 124 and the second connecting wall 124 are integrally formed, so that the structure is simple and the processing is convenient.
Of course, in other embodiments, when the cover plate is, for example, a cambered cover plate, the transparent wall has the same cambered surface as the cambered cover plate, that is, the shape of the transparent wall is the same as that of the cambered cover plate.
While the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, which are illustrative and not restrictive, and it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
