[0002] Optical film materials are a type of thin film materials specifically designed to change the behavior of light. They are usually applied to various optical and optoelectronic devices. These film materials can achieve specific functions by controlling the characteristics of light such as reflection, light transmission, absorption, polarization, etc., such as improving contrast, enhancing color saturation, reducing energy consumption, or improving visual comfort.

[0003] However, in order to meet the application requirements of optical film materials and ensure the quality and reliability of the final products, it is usually necessary to perform optical performance quality detection on the newly produced optical film materials, such as light transmittance, reflectivity, and refractive index, etc. Among them, the light transmittance refers to the ratio of the intensity of the transmitted light to the intensity of the incident light after the light passes through the optical film material. This parameter is crucial for many application fields because it directly affects the performance of the final product and the user experience.

[0004] Currently, when detecting the light transmittance of optical film materials, usually a light source is used to irradiate the optical film material, and then on the other side of the optical film material, a light transmittance detector is used to receive the penetrated light signal, thereby completing the detection and evaluation of the light transmittance of the optical film material.

[0043] Through the setting of the above structure, the cleaned optical film will move between the two dust-free cloths 63. At this time, the electric heating pipe 61 in the preheating box 6 will generate heat in the preheating box 6, and the heat will pass through the heat conduction groove 621 and be transferred to the dust-free cloth 63, so as to preheat the optical film, realize the removal of the liquid attached to the surface of the optical film, and at the same time make the optical film reach a stable temperature state, reduce the measurement error caused by the environmental temperature fluctuation, effectively improve the detection accuracy, and at the same time eliminate the internal stress of the optical film, make the optical film return to a more natural state, so as to provide more accurate test results; and when the linkage shaft 42 rotates, with the setting of the turntable 422 and the push-pull rod 73, it will drive the piston plate 72 to reciprocate in the piston box 71. When the piston plate 72 slides towards the side that compresses the gas inside the piston box 71, the gas inside the piston box 71 will enter the driving box 64 along the air outlet pipe 74, so as to push the driving sliding plate 641 to drive the translation plate 62 to slide and compress the return spring 652 inside the driven box 65. When the piston plate 72 resets, under the rebounding action of the return spring 652, the translation plate 62 will reset and slide.

Secondly, the wear situation that the optical film may encounter during actual use is simulated, so as to evaluate the durability and stability of the optical film in the real application environment, and further improve the detection effect.

[0044] Refer to Figure 1 、 Figure 9 and Figure 10, wherein a fixed seat 7 is fixedly connected to the side wall of the filter disc 5, a piston box 71 is fixedly connected to the side wall of the fixed seat 7, a piston plate 72 is slidably connected in the piston box 71, a push-pull rod 73 is hinged to the side wall of the piston plate 72, the bottom end of the linkage shaft 42 is fixedly connected with a turntable 422, the other end of the push-pull rod 73 is rotatably connected to the turntable 422, an air outlet pipe 74 is fixedly connected and communicated with the side wall of the piston box 71, and the other end of the air outlet pipe 74 is communicated with the inner cavity of the driving box 64; a backwash groove 75 is formed in the fixed seat 7, a plurality of groups of backwash holes 751 are equidistantly formed in the side of the backwash groove 75 facing the inner cavity of the filter disc 5, sealing plates 76 are fixedly connected to both sides of the lower part of the inner cavity of the filter disc 5, the side walls of the multi-layer filter membranes 51 are attached to the sealing plates 76, a backwash pipe 77 is fixedly connected to the bottom end of the fixed seat 7, one end of the backwash pipe 77 is communicated with the inner cavity of the backwash groove 75, the other end of the backwash pipe 77 is communicated with the inner cavity of the driven box 65, and a one-way valve is arranged in the backwash pipe 77.

[0045] It should be noted that the one-way valve in the backwash pipe 77 only allows the gas in the driven box 65 to enter the backwash groove 75.

[0046] Through the above structural arrangement, during the process of the return spring 652 being compressed, the driven sliding plate 651 also compresses the gas in the driven box 65 and opens the one-way valve in the backwash pipe 77, so that the gas enters the backwash groove 75 along the backwash pipe 77, and then is blown to the multi-layer filter membranes 51 in the bottom cavity of the filter disc 5 by the plurality of groups of backwash holes 751, thereby reversely flushing the multi-layer filter membranes 51, reducing the attached impurities on the multi-layer filter membranes 51, improving the filtering effect of the multi-layer filter membranes 51, and prolonging the service life of the multi-layer filter membranes 51.

[0047] Refer to Figure 8 、 Figure 9 , wherein an air extraction pipe 78 is fixedly connected and communicated with the side wall of the driven box 65, the other end of the air extraction pipe 78 is communicated with the inner cavity of the detection box 1, a one-way valve is arranged in the air extraction pipe 78, the input end of the air extraction pipe 78 is located above the top flat plate of the light transmittance detector 81, an empty groove 811 is formed in the side of the top flat plate of the light transmittance detector 81 close to the input end of the air extraction pipe 78, and a filter screen is arranged at the input end of the air extraction pipe 78 to prevent dust and impurities from entering the driven box 65.

[0048] It should be noted that the one-way valve in the air extraction pipe 78 only allows the gas in the detection box 1 to enter the driven box 65.

[0049] With the above structure set, when the driven slide plate 651 resets and slides under the rebounding action of the return spring 652, a suction force is generated inside the driven box 65, thereby opening the one-way valve in the air extraction pipe 78, causing the airflow above the top flat plate of the light transmission detector 81 to move towards the empty slot 811, thereby cleaning the dust and impurities that have accidentally fallen onto the top flat plate of the light transmission detector 81, ensuring the detection quality of the light transmission detector 81.

[0050] Embodiment 2:

[0051] Referring to Figures 1 - 10 , which is basically the same as Embodiment 1. On the basis of Embodiment 1, a quality inspection process for optical film materials production is proposed, and the steps are as follows:

[0052] Step 1: Pass the optical film material through the detection box 1 and continuously pull it forward.

[0053] Step 2: Rinse the surface of the moving optical film material.

[0054] Step 3: Perform friction and preheating treatment on the surface of the rinsed optical film material to simulate the detection environment.

[0055] Step 4: Continuously detect the processed optical film material using the light transmission detection component.

[0056] Referring to Figures 1 - 10 , in the present invention, when in use, the optical film material is passed through the inside of the detection box 1 along each guiding roller 2 and continuously pulled forward. At the same time, the driving motor 43 is turned on, causing it to drive the linkage shaft 42 and the guide vane impeller 421 to rotate in the guide vane disc 4, thereby generating a guiding effect in the guide vane disc 4, causing the deionized water at the concave bottom of the inner cavity of the detection box 1 to be continuously pumped into the guide vane disc 4 along the liquid inlet pipe 41 and enter the liquid guide pipe 3 along the liquid outlet pipe 44. Finally, the upper rinsing pipe 31 and the lower rinsing pipe 32 simultaneously spray deionized water onto the surface of the optical film material to comprehensively rinse the surface of the optical film material, ensuring the cleanliness of the surface of the optical film material, and thus improving the subsequent detection accuracy; and the rinsed deionized water will flow back into the concave part of the inner cavity of the detection box 1, and after being filtered by the multi-layer filter membrane 51, it is continuously used for subsequent cleaning, realizing the recycling of the cleaning liquid, improving the energy-saving effect, and under the driving action of the bevel gear set 52, when the linkage shaft 42 rotates, the multi-layer filter membrane 51 will be rotated, thereby continuously switching the filtering surface of the multi-layer filter membrane 51, effectively improving the filtering effect.

[0057] Next, the cleaned optical film material will move between two groups of dust-free cloths 63. At this time, the electric heating tube 61 in the preheating box 6 will generate heat in the preheating box 6, and the heat will pass through the heat conduction groove 621 to the dust-free cloth 63, so as to preheat the optical film material, remove the liquid attached to the surface of the optical film material, and at the same time make the optical film material reach a stable temperature state, reduce the measurement error caused by environmental temperature fluctuations, effectively improve the detection accuracy, and at the same time eliminate the internal stress of the optical film material, make the optical film material return to a more natural state, so as to provide more accurate test results. And when the linkage shaft 42 rotates, with the settings of the turntable 422 and the push-pull rod 73, it will drive the piston plate 72 to slide back and forth in the piston box 71. When the piston plate 72 slides toward the side that compresses the gas inside the piston box 71, the gas in the piston box 71 will enter the drive box 64 along the air outlet pipe 74, so as to push the drive slide plate 641 to drive the translation plate 62 to slide and compress the return spring 652 in the driven box 65. When the piston plate 72 returns, under the action of the rebound of the return spring 652, the translation plate 62 will slide back to its original position. In this way, the two translation plates 62 will drive the two dust-free cloths 63 to slide back and forth on the surface of the optical film material. In this way, firstly, the cleaning effect of the liquid is improved, and secondly, the wear situation that the optical film material may encounter during actual use is simulated, so as to evaluate the durability and stability of the optical film material in the real application environment, and then the detection effect is improved.

[0058] In addition, during the process of the return spring 652 being compressed, the driven slide plate 651 will also compress the gas in the driven box 65 and open the one-way valve in the counterflush pipe 77, so that the gas enters the counterflush groove 75 along the counterflush pipe 77, and then is blown to the multi-layer filter film 51 in the bottom cavity of the filter disk 5 that rotates through multiple counterflush holes 751, so as to perform reverse flushing on the multi-layer filter film 51, reduce the attached impurities on the multi-layer filter film 51, improve the filtering effect of the multi-layer filter film 51, and extend the service life of the multi-layer filter film 51. Finally, when the processed optical film material moves below the light source 8, the light transmission detector 81 will receive the optical signal passing through the optical film material, so as to detect the light transmittance of the optical film material. And when the driven slide plate 651 slides back to its original position, a suction force will be generated in the driven box 65, so as to open the one-way valve in the air extraction pipe 78, so that the air flow above the top flat plate of the light transmission detector 81 moves toward the empty groove 811, so as to clean the dust and impurities that accidentally fall on the top flat plate of the light transmission detector 81, ensuring the detection quality of the light transmission detector 81.

[0059] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
