DETAILED DESCRIPTION
[0017] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.
[0018] According to the optical transfer film testing system of the embodiment of the present invention, the optical transfer film testing system includes an adhesion testing mechanism, a weather resistance testing mechanism, a light conversion rate testing mechanism and a conveying mechanism. The adhesion testing mechanism includes a substrate, an adsorbent 10 and a tension measuring device. The adsorbent 10 is arranged on the substrate to adsorb the optical transfer film to be tested and the carrier. The tension measuring device is connected to the adsorbent 10 to detect the tension on the optical transfer film to be tested. The weather resistance testing mechanism includes a first test box 1, a heating element 2, a cooling element 3 and an ultraviolet aging element 4. The heating element 2, the cooling element 3 and the ultraviolet aging element 4 are located on the test box to test the optical transfer film to be tested in the test box. The optical transfer film is processed, and the optical conversion rate testing mechanism includes a second test box 5, a spectrophotometer, a carrier fixing part 6, a grabber and an optical power meter 7. The grabber delivers the carrier to the carrier fixing part 6. The spectrophotometer emits light to the carrier on the carrier fixing part 6 in the second test box 5. The optical power meter 7 detects the light intensity on the other side of the optical transfer film to be tested to test the optical conversion rate of the optical transfer film to be tested on the carrier. The conveying mechanism includes a conveyor belt 8. The conveyor belt 8 is used to transfer the optical transfer film to be tested and the carrier. The conveyor belt 8 passes through the first test box 1 and the second test box 5 in sequence and is connected to the substrate to transport the optical transfer film to be tested to the substrate. During the test, the optical transfer film to be tested is first subjected to a weather resistance test, and after completing the weather resistance environment simulation, the change in the optical conversion efficiency of the optical transfer film to be tested is detected. Finally, a destruction experiment is performed on the optical transfer film to measure the change in the adhesion of the optical transfer film, thereby improving the measurement efficiency and measurement accuracy.
[0019] The optical transfer film testing system according to the embodiment of the present invention has the advantages of simulating various testing environments and having high measurement efficiency.
[0020] In some embodiments, the first test box 1 has at least three chambers, the heating element 2, the cooling element 3 and the UV aging element 4 are respectively arranged in a chamber, the rotating rod 9 passes through the chamber in turn and drives the carrier and the light transfer film to be tested to rotate in the chamber, the rotating rod 9 is detachably connected to the carrier through a magnetic suction part, an opening is set at the bottom of the chamber for the carrier to enter and exit, and the conveyor belt 8 is located below the chamber.
[0021] Specifically, a heating element 2, a cooling element 3 or an ultraviolet aging element 4 is arranged in each chamber to simulate an environmental condition to simulate the influence of different environmental factors on the light transfer film, such as high heat, low temperature, and high ultraviolet environment. The light transfer film can be tested under multiple different environmental conditions to comprehensively evaluate its weather resistance. The separate chambers can ensure the precise control of the test conditions and improve the reliability of the test results. The rotating rod 9 drives the carrier to rotate in the chamber to facilitate changing the position of the carrier. After the carrier and the rotating rod 9 are fixed by a magnetic suction member, the carrier is subjected to a weather resistance test. After the test is completed, the rotating rod 9 rotates the carrier so that the carrier falls on the conveyor belt 8, and the conveyor belt 8 transports the carrier to the light conversion rate test mechanism for testing. The opening at the bottom of the chamber allows the carrier to enter and exit, reducing manual participation and improving the test efficiency of the carrier. The heating element 2 can be heated by a resistance wire, the cooling element 3 can be a cold source such as liquid nitrogen or a semiconductor refrigeration sheet, and the ultraviolet aging element 4 uses an ultraviolet lamp.
[0022] In some embodiments, the magnetic attraction member includes an electromagnet and a magnetic member. The electromagnet is located on the rotating rod 9 and corresponds to the chamber one by one, and the magnetic member is located on the carrier.
[0023] Specifically, the electromagnet and the magnetic part cooperate to allow the carrier and the optical transfer film to be measured to be attached and released quickly and repeatedly. The magnetic part is a permanent magnet. When the electromagnet is energized, magnetism is generated. The electromagnet and the magnetic part are magnetically adsorbed to fix the carrier. When the electromagnet is powered off, the magnetism disappears, the magnetic part detaches from the electromagnet, and the carrier detaches from the rotating rod 9.
[0024] In some embodiments, a spraying member 11 is further included. The spraying member 11 is located in the chamber and is used to spray liquid onto the light transfer film to be measured.
[0025] Specifically, the spraying element 11 can spray liquid evenly onto the surface of the light transfer film to be tested, simulating the effect of rain or other liquids on the light transfer film, testing the performance of the light transfer film under wet conditions, and ensuring its durability and reliability in practical applications. Optionally, the spraying element 11 is connected to two water source tanks, one is a normal water tank to simulate rainwater, and the other is a salt water tank to simulate salt erosion.
[0026] In some embodiments, the spraying element 11 and the cooling element 3 are located in the same chamber.
[0027] Specifically, combining spraying and cooling in the same chamber can simulate a cold and wet environment, and more realistically reflect the performance of the light transfer film in bad weather. The spraying element 11 and the cooling element 3 can be opened separately, enriching the function of the chamber.
[0028] In some embodiments, the grabbing member includes a first push rod 12, a clamping jaw 13 and a sliding seat 14, the sliding seat 14 is slidably connected to the inner wall of the second test box 5, and a rotating part is provided at the telescopic end of the first push rod 12, and the rotating part is connected to the clamping jaw 13 to drive the clamping jaw 13 to rotate.
[0029] Specifically, a slide rail is provided on the inner wall of the second test box 5, and the sliding seat 14 slides up and down along the slide rail to drive the first push rod 12 to move in the vertical direction, and the first push rod 12 can drive the clamping claw 13 to move in the horizontal direction. The first push rod 12 cooperates with the slide rail to complete the grasping of the grasping member in the second test box 5. The clamping claw 13 adopts an electric clamping claw 13, and the rotating part realizes the rotation connection between the clamping claw 13 and the first push rod 12, which can change the position of the carrier. After the clamping claw 13 clamps the carrier, the rotating part drives the clamping claw 13 to rotate to flip the carrier, and the light transfer film to be tested on the carrier is fixed with the carrier fixing part 6, and the first push rod 12 pushes the carrier to the target position, which improves the degree of test automation, reduces manual operation, and ensures the accuracy and repeatability of the test.
[0030] In some embodiments, the first side of the carrier fixing member 6 is adjacent to the optical power meter 7, and the second side of the carrier fixing member 6 is adjacent to the light source. The carrier fixing member 6 has two light holes, one of which corresponds to the carrier, and the other is vacant. The spectrophotometer divides the incident light from the light source into two paths and enters the two light holes respectively. A filter is set on the first side of the light hole corresponding to the carrier.
[0031] Specifically, the incident light of the light source is divided into two paths by the spectrophotometer, one path is converted by the light transfer film to be measured, and the other path is not converted. The filter is used to filter out the unconverted part of the incident light, and the light conversion rate of the light transfer film is judged by comparing the intensity of the two outgoing lights. A magnet or an electromagnet is provided on the carrier fixing member 6 to magnetically adsorb and fix the carrier to facilitate fixing the carrier.
[0032] In some embodiments, a plurality of adsorption holes are disposed at the first end of the adsorption member 10, the second end of the adsorption member 10 is connected to the tension measuring device, and a vacuum adsorption hole is disposed on the substrate to fix the carrier.
[0033] Specifically, the adsorption component 10 adsorbs the phototransfer film to be tested through multiple adsorption holes, the tension measuring device is connected to the adsorption component 10 to peel off the phototransfer film to be tested, and the vacuum adsorption holes on the substrate adsorb and fix the carrier, thereby judging the adhesion strength of the phototransfer film by measuring the tension separating the phototransfer film from the carrier. Multiple adsorption holes can provide uniform adsorption force to ensure that the phototransfer film to be tested remains stable during the test.
[0034] In some embodiments, the tension measuring device includes a tension sensor, a tension spring 15 and a cylinder 16. The cylinder 16 is located above the substrate. The cylinder 16 is connected to the adsorption member 10 through the tension spring 15. The tension sensor contacts the tension spring 15 to detect tension.
[0035] Specifically, the tension sensor can detect the degree of deformation of the tension spring 15 to determine the tension exerted on the tension spring 15. The cylinder 16 is used to drive the tension spring 15 and the adsorption component 10 to rise. The cooperation between the tension sensor and the tension spring 15 helps to accurately control the test conditions and ensure the accuracy and repeatability of the adhesion test, which is crucial for product quality control.
