When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0035] In addition, the words "first", "second" and similar words used in this application do not indicate any order, quantity or importance, but are only used to distinguish different parts.

[0037] All terms used in this application have the same meaning as those understood by those of ordinary skill in the art to which this application belongs, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries, such as general dictionaries, should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined herein.

[0038] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0039] Normally, after the cover glass is manufactured, a spectrophotometer is needed to test the Lab value (L is the brightness of the color, a is the red-green value of the color, and b is the yellow-blue value of the color) and reflectivity of the cover glass to confirm whether the cover glass meets the pre-design requirements.

[0040] During the test, the inspector holds the cover glass in one hand and the spectrophotometer in the other, and points the light output side of the spectrophotometer toward the cover glass for testing. However, the inspector's two hands are prone to relative displacement (such as shaking), and the displacement directions and displacement amounts of different cover glasses of the same model are different, resulting in inconsistent measurement points of the same model of cover glasses, which in turn interferes with the analysis results.

[0041] In order to solve the above problems, the usual practice is to provide a limit device to limit the position of the hands of the inspector respectively. However, due to the large workload and long duration of the inspection, the hands of the inspector are kept in the same posture for a long time under the limit of the limit device, which easily leads to numbness of both hands. The present application provides an optical inspection device, which is provided with a workbench and a positioning member. The cover glass to be inspected, the positioning member and the spectrophotometer can be stacked in sequence on the inspection area of ​​the upper surface of the workbench, so that the position of the spectrophotometer relative to the cover glass is fixed, so that the measurement points of the cover glass of the same model are consistent, thereby improving the accuracy of the analysis results.

[0042] The present application embodiment provides an optical detection device, see Figures 1 to 11 As shown, the optical detection device includes: a workbench 1 and a positioning member 2, the upper surface of the workbench 1 is provided with a detection area 11; at least a portion of the positioning member 2 can be opposite to the detection area 11, a detection space 21 is provided between the side of the positioning member 2 corresponding to the detection area 11 and the detection area 11, a support space 22 is provided on the side of the positioning member 2 away from the detection area 11, and the positioning member 2 is provided with a light-transmitting marking detection point 23 corresponding to the detection space 21 and the support space 22.

[0043] In the workbench 1, its lower surface can contact the ground to support the workbench 1 on the ground, or contact the tabletop to support the workbench 1 on the tabletop, or contact other planes to support the workbench 1 on other planes. A detection area 11 is set on its upper surface. The shape of the detection area 11 can be adapted to the shape of the cover glass 4 to directly place and support the cover glass 4 of the corresponding shape, or it can be flat to place and support the support mold 3 and the cover glass 4 on the support mold 3 below, or it can be other settings; wherein, when the detection area 11 is flat and in order to fix the flat cover glass 4 or the support mold 3 placed in the detection area 11 in the detection area 11 so as not to slide away from the detection area 11, the surface of the detection area 11 can be a surface with rubber, silicone or a concave-convex texture to increase friction, or it can be a surface with a limiting convex portion corresponding to the position of the cover glass 4 / support mold 3 around the side, or it can be other settings.

[0044] At least part of the positioning member 2 can be opposite to the detection area 11, a detection space 21 is set between the side of the positioning member 2 corresponding to the detection area 11 and the detection area 11, and a support space 22 is set on the side of the positioning member 2 away from the detection area 11, which can be as follows: Figures 1 to 4 and Figure 7 The cover glass 4 and the positioning member 2 shown are stacked in sequence on the detection area 11, the space where the cover glass 4 is located is the detection space 21, and the side of the positioning member 2 facing away from the cover glass 4 is vacant to form a support space 22 on which the spectrophotometer 5 can be stacked; the positioning member 2 can also be connected to the top of the detection area 11 through a connecting rod, a connecting plate or other structures, and there is a distance between the positioning member 2 and the detection area 11 to form the detection space 21, and at least part of the top of the positioning member 2 is vacant to form the support space 22 on which the spectrophotometer 5 can be stacked; the positioning member 2 can also be connected to the workbench 1 through sliding, rotating or other activities, and after sliding, rotating or other activities relative to the workbench 1, at least part of the positioning member 2 is located above the detection area 11 and there is a distance between the detection area 11 to form the detection space 21, and at least part of the top of the positioning member 2 is vacant to form the support space 22 on which the spectrophotometer 5 can be stacked. The positioning member 2 is provided with a light-transmitting marking detection point 23 corresponding to the detection space 21 and the support space 22. The light-transmitting marking detection point 23 can be as follows: Figures 3 to 5 , Figure 7 and Fig.10 The third through hole form shown can also be a circular mark printed on the positioning member 2 and the positioning member 2 inside the circular mark is made of transparent material. It can also be other settings, for example: the positioning member 2 as a whole is a transparent plastic film, a transparent glass sheet, etc.

[0045] In one example, see Figure 4 As shown, the optical detection device includes: a workbench 1 and a positioning member 2, the upper surface of the workbench 1 is provided with a detection area 11; the cover glass 4, the positioning member 2 and the spectrophotometer 5 can be stacked in the detection area 11 in sequence, after stacking, the cover glass 4 is located in the detection space 21 between the detection area 11 and the positioning member 2, the positioning member 2 is opposite to the detection area 11, the spectrophotometer 5 is located in the support space 22 of the positioning member 2 away from the detection area 11, and the light emitting member of the spectrophotometer 5 is opposite to the marked detection point 23 of the positioning member 2, so that the light emitted by the light emitting member can pass through the marked detection point 23 on the positioning member 2 to the cover glass 4, so as to detect the Lab value and reflectivity value of the ink area 41 corresponding to the marked detection point 23 on the cover glass 4. Among them, the detection area 11 corresponds to a horizontal plane, and the upper and lower surfaces of the cover glass 4 correspond to two horizontal planes, that is, this embodiment detects the planar cover glass 4 (such as: 2D glass).

[0046] In one example, see Figure 7As shown, the optical detection device includes: a workbench 1 and a positioning member 2, and a detection area 11 is set on the upper surface of the workbench 1; the supporting mold 3, the cover glass 4, the positioning member 2 and the spectrophotometer 5 can be stacked in the detection area 11 from bottom to top in sequence. After stacking, the cover glass 4 is located in the detection space 21 between the supporting mold 3 and the positioning member 2, the positioning member 2 is opposite to the detection area 11, the spectrophotometer 5 is located in the supporting space 22 of the positioning member 2 away from the detection area 11, and the light-emitting member of the spectrophotometer 5 is opposite to the marked detection point 23 of the positioning member 2, so that the light emitted by the light-emitting member can pass through the marked detection point 23 on the positioning member 2 to the cover glass 4, so as to detect the Lab value and reflectivity value of the ink area 41 corresponding to the marked detection point 23 on the cover glass 4. Among them, the detection area 11 corresponds to a horizontal plane, the lower surface of the supporting mold 3 corresponds to a horizontal plane, the surfaces of the supporting mold 3 and the cover glass 4 that contact each other are both downwardly concave curved surfaces, the positioning member 2 that fits the cover glass 4 also presents a downwardly concave curved surface, and the spectrophotometer 5 is supported at both ends of the supporting mold 3 away from the detection area 11, that is, this embodiment detects the curved cover glass 4 (such as: 2.5D glass, 3D glass).

[0047] In this embodiment, the optical detection device includes: a workbench 1 and a positioning member 2. The workbench 1 can be placed on a flat surface such as the ground or a desktop. The cover glass 4 to be detected, the positioning member 2 and the spectrophotometer 5 can be stacked in sequence on the detection area 11 on the upper surface of the workbench 1 or on the supporting mold 3 of the detection area 11, so that the position of the spectrophotometer 5 relative to the cover glass 4 is fixed, so that the measurement points of the cover glasses 4 of the same model are consistent, thereby improving the accuracy of the analysis results, and at the same time reducing the probability of relative displacement between the spectrophotometer 5 and the cover glass 4 to cause scratches on the cover glass 4, and reducing the probability of numbness of the hands of the detection personnel; further, a mark detection point 23 is provided on the positioning member 2, and the spectrophotometer 5 can be stacked at the position of the alignment mark detection point 23, so that the measurement points of the cover glasses 4 of the same model can be further consistent, thereby improving the accuracy of the analysis results. In addition, for the inspection of large-sized cover glass 4, the current method requires one person to lift the cover glass 4 and another person to hold the spectrophotometer 5 for inspection. In this embodiment, one person can place the cover glass 4 on the inspection area 11 or the supporting mold 3 on the inspection area 11, so as to reduce the number of inspection personnel.

[0048] It is understandable that after the same position of the same model of cover glass 4 is tested to obtain multiple test data, the multiple test data can be analyzed to confirm whether there are problems in the design and manufacturing process of the same position of the same model of cover glass 4.

[0049] In some embodiments, see Figures 1 to 4 and Figure 7 As shown, the workbench 1 is provided with a first space, the colors of different positions of the inner wall of the first space are consistent, and part of the detection area 11 is a light-transmitting area corresponding to the first space and the outer side of the workbench 1 respectively; part of the multiple marking detection points 23 of the positioning member 2 is opposite to the light-transmitting area.

[0050] The light-transmitting area may be a portion of the workbench 1 that is a light-transmitting structure, or may be a through hole corresponding to the first space and the outside of the workbench 1 , such as the portion of the first through hole 12 described below that forms the light-transmitting area. When the light-emitting element on the spectrophotometer 5 is opposite to the mark detection point 23 on the positioning member 2 that is not opposite to the light-transmitting area, the spectrophotometer 5 can detect the ink area 41 at the position of the corresponding mark detection point 23 on the cover glass 4; when the light-emitting element on the spectrophotometer 5 is opposite to the mark detection point 23 on the positioning member 2 that is opposite to the light-transmitting area, the spectrophotometer 5 can detect the non-ink area (i.e., transparent area 42) at the position of the corresponding mark detection point 23 on the cover glass 4, and when detecting, the light emitted by the light-emitting element of the spectrophotometer 5 passes through the mark detection point 23, the non-ink area of ​​the cover glass 4, and the light-transmitting area to the inner wall of the first space, and then reflects back to the spectrophotometer 5 to obtain the detection result. Since the colors of different positions of the inner wall forming the first space are consistent, the influence of the inconsistency of multiple detection results of the same cover glass 4 can be reduced, so that the detection is repeatable.

[0051] In some embodiments, see Figure 1 , Figure 3 , Figure 4 and Figure 7 As shown, the workbench 1 is provided with a first through hole 12 connecting the first space and the outside of the workbench 1, and at least a portion of the first through hole 12 is located in the detection area 11 to form a light-transmitting area. In other words, the light-transmitting area is in the form of a through hole, so that the non-ink area of ​​the cover glass 4 can be detected, and the material used for the workbench 1 can be reduced, thereby reducing the manufacturing cost of the workbench 1.

[0052] In some embodiments, see Figures 1 to 6 As shown, the detection area 11 is a horizontally extending plane, and the positioning member 2 is a flat membrane, and is parallel to the detection area 11. In this way, the detection space 21 between the positioning member 2 and the detection area 11 can detect the flat cover glass 4, and the structure of this arrangement is simple and easy to manufacture.

[0053] In some embodiments, see Figures 7 to 11As shown, the detection area 11 is in the shape of a horizontally extending plane; the optical detection device also includes: a supporting mold 3, which is arranged in the detection area 11, the supporting mold 3 can be placed in the detection area 11 and fixed relative to the detection area 11, the supporting mold 3 is provided with a second through hole 31 corresponding to the first through hole 12, and the surface of the supporting mold 3 facing away from the detection area 11 has an arc-shaped surface 32; the positioning member 2 is an arc-shaped diaphragm, which is adapted to the arc-shaped surface 32, and there is a detection space 21 corresponding to the arc-shaped surface 32.

[0054] The supporting mold 3 can be placed in the detection area 11 and fixed relative to the detection area 11. The surface of the supporting mold 3 in contact with the detection area 11 can be a plane, a plane with a concave portion, or other settings that can be placed in the detection area 11 and fixed relative to the detection area 11, so that the supporting mold 3 placed in the detection area 11 will not slide away from the detection area 11. The supporting mold 3 is provided with a second through hole 31 corresponding to the first through hole 12, so that the light emitted by the light emitting part of the spectrophotometer 5 can pass through the marking detection point 23, the non-ink area of ​​the cover glass 4, the second through hole 31, the first through hole 12 to the first space and then reflect to the spectrophotometer 5 to detect the non-ink area of ​​the cover glass 4. The surface of the supporting mold 3 away from the detection area 11 has an arc surface 32, and the positioning member 2 is an arc diaphragm, which is adapted to the arc surface 32, and there is a detection space 21 corresponding to the arc surface 32, so that the detection space 21 can detect the curved cover glass 4.

[0055] In specific implementation, the positioning member 2 of the flat diaphragm in the previous embodiment and the combination of the positioning member 2 and the supporting mold 3 of the curved diaphragm in this embodiment can be replaced with each other to quickly switch between detecting the flat cover glass 4 and the curved cover glass 4.

[0056] In some embodiments, see Figures 8 to 11 As shown, the surface of the supporting mold 3 corresponding to the positioning member 2 includes: a first surface 33, a second surface 34 and a third surface 35, the second surface 34 is located between the first surface 33 and the third surface 35 and is a concave arc surface 32, the first surface 33 and the third surface 35 are located on the same horizontal plane and are both convex from the second surface 34. In this way, the second surface 34 can place and support the curved cover glass 4, and the first surface 33 and the third surface 35 can support the spectrophotometer 5.

[0057] Here, the first surface 33 and the third surface 35 may be symmetrical with respect to the second surface 34 , so that the supporting mold 3 has symmetrical beauty and the support for the spectrophotometer 5 is more stable.

[0058] In some embodiments, the inner wall forming the first space is provided with a black light absorbing layer. Compared with other colors, black has light absorbing properties, so that the probability of its participation in reflection can be reduced, thereby reducing the influence of the color of the inner wall on the detection result.

[0059] In some embodiments, see Figures 1 to 4 and Figure 7 As shown, the workbench 1 includes: a frame structure 13, a support column 14, a bottom plate structure 15 and a top plate structure 16. The frame structure 13 is connected end to end by a plurality of side plates 131 to form a structure with upper and lower ends opened. The support column 14 is correspondingly connected between two adjacent side plates 131 and extends in the vertical direction respectively. The bottom plate structure 15 and the top plate structure 16 respectively close the upper and lower ends of the frame structure 13 to form a first space. The top plate structure 16 is provided with a detection area 11; wherein the frame structure 13, the bottom plate structure 15, and the top plate structure 16 respectively include a black light absorbing plate, and the support column 14 is a black support column 14, so that the inner wall forming the first space is black. The workbench 1 has a simple structure and is easy to manufacture.

[0060] Here, the support column 14 can be made of a material with high structural strength such as a stainless steel square tube to improve the supporting strength of the workbench 1 and extend the service life of the support column 14 .

[0061] In some embodiments, the top plate structure 16 includes: a top plate, an electrostatic layer and a flexible layer. The top plate is a black light-absorbing plate and the inner wall corresponding to the first space is black. The electrostatic layer and the flexible layer are stacked in sequence on the side of the top plate facing away from the first space, and the top plate, the electrostatic layer and the flexible layer are opened with corresponding holes in sequence to form a light-transmitting area.

[0062] The electrostatic layer can be an electrostatic structure such as electrostatic rubber to reduce the generation of static electricity during the detection process; the flexible layer can be a polytetrafluoroethylene layer to protect the cover glass 4 or the supporting mold 3 in direct contact therewith, thereby reducing the probability of scratches on the cover glass 4 or the supporting mold 3.

[0063] In some embodiments, see Figure 4 , Figure 5 and Figure 7 As shown, the marking detection point 23 is a third through hole with openings at both ends, and the openings at both ends of the third through hole correspond to the detection area 11 and the departure detection area 11 respectively.
