[0037] Based on the inaccuracies in the measurement results of existing detection devices, this embodiment proposes a multi-angle adjustment device for coating film detection, which mainly includes a base, a first glass side plate 201, a second glass side plate 202, and a connection component. Among them, the adjustment component at least includes an adjustment screw 401. One end of the adjustment screw 401 abuts against the vertical plate 303. By squeezing the vertical plate 303, the position adjustment of the first glass side plate 201 and the second glass side plate 202 is completed, realizing multi-angle changes of the matching block. In this way, only one matching block is needed to achieve multi-angle testing, without the need to repeatedly replace the test matching block, replacing the traditional method of replacing the matching block. Moreover, it causes little damage to the test sample, is easy to operate, and has high measurement result accuracy.

[0038] Preferably, both the first concave frame and the second concave frame are U-shaped. The first glass side plate 201 is embedded in the first concave frame, and the second glass side plate 202 is embedded in the second concave frame.

[0040] Specifically, according to Figure 1 , the adjustment device proposed in this embodiment includes a base, which includes a bottom plate 101 and a glass plate 102 connected to one end of the bottom plate 101. The glass plate 102 is perpendicular to the bottom plate 101, forming an L shape as a whole. At both ends of one surface of the glass plate 102, there are parallel first convex strips 103 and second convex strips 104. The height of the first convex strip 103 is preferably the same as the height of the glass plate 102, and the bottom end of the first convex strip 103 is tightly connected to the bottom plate 101. Similarly, the height of the second convex strip 104 is preferably the same as the height of the glass plate 102, and the bottom end of the second convex strip 104 is tightly connected to the bottom plate 101.

[0041] In a preferred implementation manner, the bottom plate 101, the glass plate 102, the first convex strip 103, and the second convex strip 104 in the base are of an integral structure, which simplifies the process flow and improves the measurement efficiency. The bottom plate 101, the first convex strip 103, and the second convex strip 104 are preferably made of the same material as the glass plate 102, that is, glass, which helps to reduce the interference of other materials on light and improve the measurement accuracy.

[0042] Further, the connecting component includes a left connecting member 301 and a right connecting member 302 which are symmetrically arranged, and a middle component connecting the left connecting member 301 and the right connecting member 302. The left connecting member 301 and the right connecting member 302 are symmetric with respect to the middle connecting member. The left connecting member 301 includes a first connecting member and a second connecting member, and an obtuse angle is formed between the first connecting member and the second connecting member. That is to say, the projections of the first connecting member and the second connecting member towards the bottom plate 101 are approximately in a V shape. Among them, the obtuse angle is preferably 120°. Similarly, the right connecting member 302 includes a first connecting member and a second connecting member, and an obtuse angle is formed between the first connecting member and the second connecting member, and the obtuse angle is preferably 120°.

[0043] Further, the first connecting member of the left connecting member 301 is provided with a first concave strip, and the second connecting member is provided with a first concave frame. The first concave strip and the second concave frame are located on both sides of the left connecting member 301. The first connecting member of the right connecting member 302 is provided with a second concave strip, and the second connecting member is provided with a second concave frame. The second concave strip and the second concave frame are located on both sides of the right connecting member 302. The first concave strip of the left connecting member 301 is inserted and slidably connected with the first convex strip 103. The second convex strip 104 of the right connecting member 302 is inserted and slidably connected with the second concave frame. The first glass side plate 201 is embedded in the first concave frame of the left connecting member 301, and the second glass side plate 202 is embedded in the second concave frame. Among them, the first glass side plate 201 and the second glass side plate 202 are preferably rectangular, occupying the largest area, facilitating the incident light to enter, improving the detection efficiency, and can also be other shapes, such as circular, triangular, etc. Among them, the shape of the first concave frame should be adapted to the shape of the first glass side plate 201, and the shape of the second concave frame should be adapted to the shape of the second glass side plate 202. In addition, the thickness of the first glass side plate 201 and the second glass side plate 202 is selected according to actual needs and should match the inner concave width of the first concave frame and the second concave frame. No specific limitation is made here.

[0044] The first concave frame and the second concave frame can be in a zigzag shape, a U shape, or an L shape. The shapes of the first concave frame and the second concave frame can be the same or different. For example, the first concave frame is in a U shape, and the first glass side plate 201 embedded in it is rectangular; the second concave frame is in a zigzag shape, and the second glass side plate 202 embedded in it is also rectangular. Both the first concave frame and the second concave frame can be in an L shape. The bottom and side parts of the first concave frame are designed to be recessed for embedding the first glass side plate 201. For the side part of the first glass side plate 201 that is not embedded, it can be adhesively connected to the vertical plate 303. Similarly, the bottom and side parts of the second concave frame are designed to be recessed for embedding the second glass side plate 202, and for the side part of the second glass side plate 202 that is not embedded, it can also be adhesively connected to the vertical plate 303. In a preferred embodiment, both the first concave frame and the second concave frame are in a U shape, and both the first glass side plate 201 and the second glass side plate 202 are rectangular, which is convenient for the first glass side plate 201 and the second glass side plate 202 to be embedded or disassembled, improving the assembly efficiency.

[0045] Furthermore, the connecting component further includes a middle connecting piece. The middle connecting piece includes a vertical plate 303 and an adjusting component connecting the first concave frame and the second concave frame. The adjusting component is located on the bottom plate 101 and is fixedly connected to one surface of the vertical plate 303. The vertical plate 303 is parallel to the glass plate 102. Among them, the base, the connecting component, the first glass side plate 201, and the second glass side plate 202 enclose a groove, and a matching liquid 501 is arranged in the groove.

[0046] The adjusting component can be an adjusting screw 401 and a connecting block 402. The connecting block 402 is fixedly arranged on the bottom plate 101, and a threaded hole matching the adjusting screw 401 is provided in the middle area of the connecting block 402. After the adjusting screw 401 passes through the threaded hole, it abuts against the vertical plate 303. When the adjusting screw 401 is rotated, the vertical plate 303 will move to the left, that is, move towards the direction of the glass plate 102, causing the first glass side plate 201 and the second glass side plate 202 to deflect at a normal angle. Every time an angle is adjusted, the current position of the adjusting screw 401 is fixed through the connecting block 402. In this way, the spectra of the reflected light and the transmitted light can be tested at multiple angles. This angle can make the included angle between the vertical plate 303 and the first glass side plate 201 and / or the second glass side plate 202 change between 130° and 150°, replacing the traditional method of continuously replacing matching blocks at different angles, improving the detection efficiency, and having high reliability of measurement data.

[0047] The adjusting assembly can also be an adjusting screw 401 and two connecting blocks 402. One of the connecting blocks 402 is fixedly arranged on the bottom plate 101, and a threaded hole matching the adjusting screw 401 is provided in the middle area of the connecting block 402. The other connecting block 402 is arranged on one surface of the vertical plate 303, and a groove matching the adjusting screw 401 is also provided in the middle of this connecting block 402. When the adjusting screw 401 is rotated and adjusted to the required angle, the two connecting blocks 402 can more stably and firmly adjust the position of the adjusting screw 401 to ensure the stability during the measurement process.

[0048] The adjusting assembly can also be an adjusting screw 401 and multiple connecting blocks 402. One of the connecting blocks 402 is fixedly arranged on the bottom plate 101, and a threaded hole matching the adjusting screw 401 is provided in the middle area of the connecting block 402. The other connecting block 402 can be adhesively attached and arranged on one surface of the vertical plate 303, and a groove matching the adjusting screw 401 is also provided in the middle of this connecting block 402. The remaining connecting blocks 402 are arranged between the above two connecting blocks 402 and fixed on the bottom plate 101, which helps to enhance the stability of operating the adjusting screw 401.

[0049] Preferably, the height of the matching liquid 501 injected into the groove is less than the height of the groove. When adjusting the adjusting screw 401, the matching liquid 501 always exists in the groove and will not overflow, ensuring the detection stability and improving the measurement accuracy.

[0050] Preferably, the refractive index of the matching liquid 501 is the same as that of the first glass side plate 201, the second glass side plate 202, and the glass plate 102; the connecting component is made of rubber. During the actual extrusion of the vertical plate 303, using rubber material not only facilitates the movement of the positions of the first glass side plate 201 and the second glass side plate 202, but this material is not easily deformed during extrusion and has a strong ability to recover from deformation. At the same time, it can also protect the first glass side plate 201 and the second glass side plate 202, further improving the detection accuracy.

[0051] In another preferred embodiment, a driving motor is further included. The adjusting screw 401 is an electric screw, and the electric screw is electrically connected to the driving motor, which can achieve precise adjustment. For example, when the electric screw rotates one circle, how far it moves towards the vertical plate 303, then the angle between the vertical plate 303 and the first glass side plate 201 and / or the second glass side plate 202 changes, and thus various angle transformations of the matching block are completed.

[0052] During actual measurement, place the bottom surface of the glass plate 102 of the multi-angle adjusting device introduced above on the coating film to be detected, or if there are two such multi-angle adjusting devices, place the coating film to be detected between the bottom surfaces of the two glass plates 102, and select according to the actual measurement requirements.

[0053] In actual measurement, a laser beam is incident on the bottom surface of the glass plate 102 from one side of the multi-angle adjustment device. The beam reflected by the interface between the coating film to be detected and the glass plate 102 exits from the first glass side surface or the second glass side surface, and the light intensity of the reflected light is measured. This reflected light carries various optical information. Alternatively, there are two multi-angle adjustment devices, and the coating film to be detected is arranged between the bottom surfaces of two glass plates 102. Then, the beam can also pass through the detection coating film and enter the next multi-angle adjustment device, and exits from the first glass side surface or the second glass side surface of this device. The transmitted light that exits is received by the detector, and this transmitted light also carries various optical information. Among them, the coating film to be detected can be a coating film formed by coating one or both sides of a glass substrate, or can also be a coating film formed by stacking coatings on each surface of multiple glass substrates. It is not limited to this. There are various coating methods as long as the film layer can be coated on the surface of the glass substrate. The specific method is selected by those skilled in the art according to actual needs.

[0054] Preferably, a rubber sealing ring is provided between the connecting component and the bottom plate 101. When operating the adjusting screw 401, the connecting component moves, and during the movement, the matching liquid 501 is ensured to be stable and will not overflow.

[0055] The above has introduced in detail a multi-angle adjustment device for detecting a coating film in an embodiment of the present application. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those of ordinary skill in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
