Detailed Description of Embodiments

[0033] To make the objectives, technical solutions, and advantages of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the drawings.

[0034] In the test of the transmittance of optical silicone rubber, if it is necessary to measure the transmittance of different rubber thicknesses, colorimetric cuvettes of different specifications need to be purchased. Since the commercial colorimetric cuvettes are non-detachable and have a very small effective test area, it is very difficult to soak and clean them, and the colorimetric cuvettes become consumables.

[0035] Please refer to Figure 1 、 Figure 2 and Figure 3 , Figure 1 is an exploded schematic view of an optical glue transmittance test device provided by an embodiment of the present application, Figure 2 is a top view of an optical glue transmittance test device provided by an embodiment of the present application, Figure 3 is a schematic structural diagram of an adjusting piece provided by an embodiment of the present application. The optical glue transmittance test device may include: a base 100, an adjusting piece 200, two supporting members 300, and two light-transmitting pieces 400.

[0036] Both of the two supporting members 300 in the optical glue transmittance test device may be located on one side of the base 100 and arranged oppositely, and at least one of the two supporting members 300 may be slidably connected to the base 100. Each supporting member 300 may have a light-passing hole a1, and the two light-passing holes a1 in the two supporting members 300 may communicate with each other. For example, the apertures of the two light-passing holes a1 in the two supporting members 300 may be equal.

[0037] The adjusting piece 200 in the optical glue transmittance test device may have a receiving space b1 and an opening b2 communicating with the receiving space b1. For example, the thickness of the adjusting piece 200 may be selected according to actual needs, and the range of the thickness of the adjusting piece 200 may be 0.1 mm - 1 m. The material of the adjusting piece 200 may be polytetrafluoroethylene.

[0038] In the optical glue transmittance testing device, the two light-transmitting sheets 400 can be respectively located on both sides of the adjusting sheet 200, and the two light-transmitting sheets 400 can be in contact with both sides of the adjusting sheet 200 to enclose a cavity b3 for accommodating the optical glue with the accommodating space b1. Here, after the light-transmitting sheet 400 and the adjusting sheet 200 are installed on the base 100, the opening b2 can be located on the side of the cavity b3 away from the base 100, and the opening b2 and the cavity b3 can be communicated, that is, the optical glue to be detected can be injected into the cavity b3 through the opening b2 in the adjusting sheet 200. Exemplarily, the material of the light-transmitting sheet 400 can be a JS-1 grade quartz sheet and is polished on both sides. The thickness range of the light-transmitting sheet 400 can be 1 mm - 3 mm. When the total thickness of the two light-transmitting sheets 400 is 2 mm, its transmittance can be greater than or equal to 86%.

[0039] Among them, when the optical glue transmittance testing device is in the testing state, the adjusting sheet 200 and the two light-transmitting sheets 400 can both be located between the two supporting members 300, and the cavity b3 enclosed by the adjusting sheet 200 and the two light-transmitting sheets 400 can be located between the two light-transmitting holes a1 in the two supporting members 300. These two supporting members 300 can be configured to: after clamping the two light-transmitting sheets 400 and the adjusting sheet 200, be firmly connected to the base 100.

[0040] Exemplarily, when using the optical glue transmittance testing device to test the optical glue transmittance, the adjusting sheet 200 with a corresponding thickness can be arbitrarily selected as needed, the adjusting sheet 200 is clamped between the two light-transmitting sheets 400 to form a detachable colorimetric cell, and the detachable colorimetric cell is placed between the two supporting members 300; then, the supporting members 300 are pushed to clamp the adjusting sheet 200 and the two light-transmitting sheets 400; after that, the glue liquid is injected into the cavity b3 of the colorimetric cell through the opening b2; finally, after the glue liquid solidifies, the optical glue transmittance testing device is installed on an ultraviolet spectrophotometer for testing. After the test is completed, the two supporting members 300 are moved and loosened, the adjusting sheet 200 and the two light-transmitting sheets 400 are taken out, and the light-transmitting sheet 400 can be separated from the adjusting sheet 200 by rotating the light-transmitting sheet 400; then the solidified colloid is scraped off and cleaned with a cleaning agent.

[0041] In the embodiment of the present application, since the cuvette formed by the adjusting piece 200 and the two light-transmitting pieces 400 is detachable, both the adjusting piece 200 and the light-transmitting piece 400 can be reused, greatly saving the test cost. In addition, by using adjusting pieces 200 with different thicknesses, the optical path length can be adjusted, and the test requirements for adhesives with different thicknesses can be met without purchasing cuvettes of different specifications, effectively increasing the test functions of the cuvette. Moreover, the specifications of the cuvette can be freely determined, and the optical path width can reach 50 mm. The large test area is beneficial to the passage of the effective light beam, further ensuring the accuracy of the detection result. Furthermore, the cuvette is directly fixed on the base 100, and the processes of glue filling - solidification - testing are completed in one step, eliminating the trouble of repeatedly wiping the cuvette when taking it back and forth. And the clamping of the adjusting piece 200 and the light-transmitting piece 400 by the sliding of the supporting member 300 has no gear position limit, increasing the freedom of the cuvette specification design.

[0042] In summary, the embodiment of the present application provides an optical glue transmittance testing device, which may include: a base, an adjusting piece, two supporting members, and two light-transmitting pieces. Since the cuvette formed by the adjusting piece and the two light-transmitting pieces is detachable, the adjusting piece and the light-transmitting piece can be reused, greatly saving the test cost. In addition, by using adjusting pieces with different thicknesses, the optical path length can be adjusted, and the test requirements for adhesives with different thicknesses can be met without purchasing cuvettes of different specifications, effectively increasing the test functions of the cuvette. Moreover, the specifications of the cuvette can be freely determined, and the optical path width can reach 50 mm. The large test area is beneficial to the passage of the effective light beam, further ensuring the accuracy of the detection result. Furthermore, the cuvette is directly fixed on the base, and the processes of glue filling - solidification - testing are completed in one step, eliminating the trouble of repeatedly wiping the cuvette when taking it back and forth. The clamping of the adjusting piece and the light-transmitting piece by the sliding of the supporting member has no gear position limit, increasing the freedom of the cuvette specification design.

[0043] Optionally, the orthographic projection of the light-transmitting hole a1 in each supporting member 300 on the plane where the adjusting piece 200 is located may cover the orthographic projection of the cavity b3 on the plane where the adjusting piece 200 is located. In this case, by covering the area where the cavity b3 is located with the light-transmitting hole a1 in the supporting member 300, it is ensured that the optical glue transmittance test area is relatively large, and more light can pass through the area where the cavity b3 is located, improving the accuracy of the optical glue transmittance test.

[0044] In the embodiment of the present application, please refer to Figure 4 , Figure 4It is a partial structural schematic diagram of an optical adhesive transmittance testing device provided in an embodiment of the present application. The base 100 in the optical adhesive transmittance testing device may have a strip groove 101 on the side facing the supporting member 300, and the target supporting member A may have a slider A1 that cooperates with the strip groove 101 on the side facing the base 100. At least a portion of the slider A1 may be located in the strip groove 101 in the base 100 and slidably connected to the strip groove 101. Among them, the extension direction of the strip groove 101 may be parallel to the sliding direction of the target supporting member A, and the target supporting member A may be the supporting member that is slidably connected to the base among the two supporting members. In this case, by providing a strip slide groove 101 on the base 100, and providing a slider that cooperates with the strip slide groove 101 in the target supporting member A, the target supporting member A can slide freely on the base 100 through the cooperation of the slider A1 and the strip slide groove 101, and can be fastened to the base 100 after sliding to clamp the adjustment sheet 200 and the two light-transmitting sheets 400 with another supporting member 300. That is, in this way, after the adjustment sheet 200 is replaced with different specifications, the two supporting members 300 can effectively clamp the adjustment sheet 200 and the two light-transmitting sheets 400.

[0045] For example, in one possible implementation, one of the two supporting members 300 can be slidably connected to the base 100, and the other supporting member 300 can be fixedly connected to the base. In another possible implementation, both of the two supporting members 300 can be slidably connected to the base 100.

[0046] Optionally, the target supporting member A may have a first locking member A2 on the side away from the light-transmitting sheet 400, and the base 100 may have a second locking member 102 that cooperates with the first locking member A2. Among them, the first locking member A2 in the target supporting member A can be configured to be fastened to the second locking member 102 after the target supporting member A slides to clamp the two light-transmitting sheets 400 and the adjusting sheet 200. In this case, since the two light-transmitting sheets 400 and the adjusting sheet 200 can be clamped by sliding toward each other by two supporting members 300, after completing the clamping function, it is only necessary to use the first locking member A2 and the second locking member 102 to fix the target supporting member A to the base 100. At the same time, it can also simplify the accuracy requirements of the two locking members and reduce the manufacturing cost. It should be noted that after the test of the optical glue transmittance test device is completed, the first locking member A2 and the second locking member 102 can be disconnected so that the target supporting member A can slide relative to the base 100 in the direction away from the other supporting member 300.

[0047] For example, the number of the first locking members A2 and the number of the second locking members 102 can both be two, and the two first locking members A2 can be located at two edge portions of the target supporting member A, respectively.

[0048] In the embodiment of the present application, please refer to Figure 4 and Figure 5 , Figure 5 which is an exploded schematic view of another optical glue transmittance testing device provided by the embodiment of the present application. The second locking member 102 in the base 100 may include: a kidney-shaped hole 102a, and the extending direction of the kidney-shaped hole 102a may be parallel to the extending direction of the strip-shaped sliding groove 101. The first locking member A2 in the target bearing member A may include: a fixing frame A21 and a locking screw A22. The fixing frame A21 may be fixedly connected to the target bearing member A. The fixing frame A21 may have a connection hole c1 communicating with the kidney-shaped hole 102a. One end of the locking screw A22 can pass through the connection hole c1 in the fixing frame A21 and then be fixedly connected to the kidney-shaped hole 102a in the base 100. In this way, after the target bearing member A moves to clamp the two light-transmitting sheets 400 and the adjusting sheet 200 with another bearing member 300, one end of the locking screw A22 can pass through the connection hole c1 and be clamped in the kidney-shaped hole 102a in the base 100.

[0049] In the present application, as Figure 5 shown, the fixing frame A21 in the first locking member A2 may include: a first fixing sheet A211 and a second fixing sheet A212. The first fixing sheet A211 may be connected to the target bearing member A. One end of the second fixing sheet A212 may be fixedly connected to the first fixing sheet A211, and the second fixing sheet A212 may be arranged parallel to the base 100. Among them, the second fixing sheet A212 may have a connection hole c1. Exemplarily, the first fixing sheet A211 and the second fixing sheet A212 may be an integral structure.

[0050] Optionally, as Figure 2 shown, an edge portion of one of the two bearing members 300 facing the other bearing member 300 may have a limiting protrusion T, and the limiting protrusion T may be configured to: contact the side surface of at least one light-transmitting sheet 400 after the two light-transmitting sheets 400 and the adjusting sheet 200 are both located between the two bearing members 300. In this case, by providing the limiting protrusion T at the edge portion of one bearing member 300 facing the other bearing member 300, in this way, during the process of installing the two light-transmitting sheets 400 and the adjusting sheet 200 on the base 100, the side surface of the light-transmitting sheet 400 can be made to contact the limiting protrusion T, so that it can be determined that the light-transmitting sheet 400 and the adjusting sheet 200 are assembled in place, improving the convenience of assembly.

[0051] In the embodiment of the present application, as Figure 5As shown in the figure, the support member 300 in the optical adhesive transmittance testing device may include: a first bottom plate 301 and two first side plates 302. The first bottom plate 301 may be connected to the base 100, and the two first side plates 302 may be fixedly connected to the two ends of the first bottom plate 301 respectively, and the first side plate 302 intersects with the first bottom plate 301. Among them, the first bottom plate 301 and the two first side plates 302 may be used to enclose a light passing hole a1 in the support member 300. In this way, a U-shaped support member can be formed by the two first side plates 302 and the first bottom plate 301. The structure of the support member 300 is simple and the manufacturing cost is relatively low. For example, the first side plate 302 may be perpendicular to the first bottom plate 301.

[0052] Optionally, please refer to Figure 6 , Figure 6 is a schematic structural diagram of another adjusting piece provided by an embodiment of the present application. The adjusting piece 200 in the optical adhesive transmittance testing device may include: a second bottom plate 201 and two second side plates 202. The two second side plates 202 may be fixedly connected to the two ends of the second bottom plate 201 respectively, and the second side plate 202 may intersect with the second bottom plate 201. Among them, the second bottom plate 201 and the two second side plates 202 may be used to enclose a receiving space b1 and an opening b2 communicating with the receiving space b1. In this way, a U-shaped adjusting piece can be formed by the two second side plates 202 and the second bottom plate 201. The structure of the adjusting piece is simple and the manufacturing cost is relatively low. For example, the second side plate 202 may be perpendicular to the second bottom plate 201.

[0053] In summary, an embodiment of the present application provides an optical adhesive transmittance testing device, which may include: a base, an adjusting piece, two support members and two light-transmitting pieces. Since the colorimetric cuvette formed by the adjusting piece and the two light-transmitting pieces is detachable, the adjusting piece and the light-transmitting piece can be reused, greatly saving the testing cost. In addition, by using adjusting pieces with different thicknesses, the optical path length can be adjusted, and different specifications of colorimetric cuvettes do not need to be purchased to meet the testing requirements of adhesives with different thicknesses, effectively increasing the testing function of the colorimetric cuvette. And the specifications of the colorimetric cuvette can be freely formulated, the optical path width can reach 50 mm, and the large testing area is beneficial to the passage of the effective light beam, further ensuring the accuracy of the detection result. Moreover, the colorimetric cuvette is directly fixed on the base, and the processes from glue filling, solidification to testing are completed in one step, saving the trouble of repeatedly wiping when taking the colorimetric cuvette back and forth. There is no gear limit for clamping the adjusting piece and the light-transmitting piece by sliding the support member, increasing the freedom of the colorimetric cuvette specification design.
