Description

Technical Field

[0001] The utility model relates to the technical field of optical film coating detection, in particular to a device for detecting optical film coatings. Background Technique

[0002] An optical film is composed of thin layered media, a type of optical dielectric material that propagates light beams through interfaces. An optical film consists of multiple different film layers, including a coating. The coating is used to protect the optical film and enhance its scratch resistance. To ensure the quality of the optical film, quality detection is required, including heat wrinkle detection. By heat wrinkle, the thermal shrinkage degree of the optical film can be judged. Take the optical film to make a specimen, then place the specimen in a forced-air constant temperature oven for heating. After keeping warm for a period of time, take out the specimen. When the specimen temperature cools to the test environment temperature, measure the specimen size, and calculate the thermal shrinkage rate of the film according to the length and width size data measured on the front and back sides of the specimen.

[0003] For example, a thermal shrinkage detection device with the publication number CN209656607U includes a tray. A glass is installed above the tray. A hook is installed on one side of the tray. The hook is connected to a handle. A steel straight ruler is directly embedded inside the tray. There are at least 2 steel straight rulers. Only need to place the tested diaphragm flat inside the tray of the device before the experiment and record the scale numbers of the steel straight rulers where the four sides of the diaphragm are located, and there is no need to mark the measurement position.

[0004] Using the above optical film coating detection device to detect the size of the optical film before detection, it can be calculated by directly observing the scale numbers on the steel straight ruler. Since the optical film will undergo thermal shrinkage during the heating process and its position will change after thermal shrinkage, it is necessary to move the optical film to the position corresponding to the 0 scale of the steel straight ruler before the corresponding scale of the optical film can be seen, and the corresponding numbers of the optical film cannot be quickly viewed.

Detailed Embodiment

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1 - 5 , the present utility model provides the following technical solutions:

[0028] A device for detecting an optical film coating, including a sealing plate 2, a constant - temperature oven 1 and a high - temperature - resistant glass 4; the sealing plate 2 is clamped on the front side of the constant - temperature oven 1, and a collecting plate 3 is slidably connected inside the constant - temperature oven 1; the high - temperature - resistant glass 4 is installed at the left end of the constant - temperature oven 1.

[0029] First, pre - heat the constant - temperature oven 1 to make the temperature inside the constant - temperature oven 1 stably reach the detection temperature. During the heat - shrinkage process of the optical film body 6, glue will flow out, and the glue drops leak onto the collecting plate 3. There are two sealing plates 2, and the sealing plates 2 are used to seal the front side of the constant - temperature oven 1, which can reduce the heat dissipation during the heating process. The setting of the high - temperature - resistant glass 4 can observe the heat - shrinkage degree of the optical film body 6 inside the constant - temperature oven 1, and the internal situation can be directly observed.

[0030] The limiting ring 11 is installed at the rear side of the sealing plate 2, and a placement frame 5 is clamped on the limiting ring 11. Through the setting of the placement frame 5, the optical film body 6 with different diameters can be limited; the optical film body 6 is placed inside the placement frame 5; a scale 12 is installed on the inner side of the placement frame 5. Through the scale 12, the height where the optical film body 6 is located can be seen. According to the height where the optical film body 6 is located, the radius of the optical film body 6 can be calculated. The angle formed by the side of the placement frame 5 and the vertical plane is 30 degrees. The placement frame 5 is set as a hollow frustum structure. The high-temperature resistant glass 4 is transparent glass. Through the high-temperature resistant glass 4, the thermal wrinkling degree of the optical film body 6 can be seen.

[0031] Place the placement frame 5 on the limiting ring 11. The limiting ring 11 can place placement frames 5 of different specifications. Place the optical film body 6 inside the placement frame 5. Observe the number corresponding to the optical film body 6 on the scale 12. Through the known angle of the placement frame 5, the initial radius of the optical film body 6 can be calculated. Then, clamp the sealing plate 2 on the front side of the constant temperature oven 1, so that the placement frame 5 is placed inside the constant temperature oven 1. The temperature inside the constant temperature oven 1 acts on the whole optical film body 6. When the optical film body 6 shrinks, it automatically falls downward due to its own weight until the inner wall of the placement frame 5 fits with the outer side of the optical film body 6. When the detection time is reached, pull the sealing plate 2 outward by hand to make the optical film body 6 on the outside. Observe the scale 12 to see the corresponding data of the shrunk optical film body 6, and calculate the radius of the shrunk optical film body 6. Through the radii of the optical film body 6 before and after, the thermal wrinkling degree can be calculated. There is no need to measure the radii of the optical film body 6 before and after, and the radius of the optical film body 6 can be quickly known.

[0032] The scraping rod 7 is attached to the inside of the placement frame 5. The scraping rod 7 rotates to scrape the stains adhered to the inner wall of the placement frame 5 to prevent it from affecting the normal placement of the optical film body 6. A connecting rod 13 is installed at the rear side of the sealing plate 2, and a fixing rod 9 is rotatably connected to the connecting rod 13. The scraping rod 7 is inserted into the fixing rod 9, and the fixing rod 9 is located below the center of the placement frame 5. Through holes 8 are opened on both the upper and lower sides of the scraping rod 7, and a limiting post 10 is inserted between the lower through hole 8 and the fixing rod 9.

[0033] Move the scraping rod 7 to fit with the inner wall of the placement frame 5. Insert the limiting post 10 into the lower through hole 8. The limiting post 10 fixes the scraping rod 7 and the fixing rod 9 together. Then, rotate the fixing rod 9 by hand. The rotation of the fixing rod 9 drives the scraping rod 7 to rotate synchronously. The rotation of the scraping rod 7 scrapes the substances adhered to the inner wall of the placement frame 5 to prevent the substances from adhering and affecting the normal placement of the optical film body 6. Then, disassemble the scraping rod 7 and clean the stains adhered to the scraping rod 7. After cleaning, insert the scraping rod 7 into the fixing rod 9, and the limiting post 10 fixes the fixing rod 9.

[0034] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
