[0038] 1. Check the accuracy of the test device through the reference component.

[0039] 2. When the test lens of the test head is above the rotating ring, the torsion spring releases the stored force to drive the rotating ring to rotate rapidly. The rotating ring drives the cleaning brush to clean the test head to avoid manual cleaning. After cleaning, it switches to the detection position. If errors still occur, it means that the test head is faulty and needs to be replaced, thereby eliminating the cause of contamination at the test end of the test head.

[0040] 3. When the caressing plate is reset, the caressing plate does not contact the color film, and the limiting shaft is at the upper part of the circular groove. In order to ensure that the limiting shaft can make a circular motion smoothly, a second magnetic plate is fixed on the outer side of the sliding support plate. When the cross plate moves to above the second magnetic plate, the limiting shaft moves to the upper part of the circular groove by the magnetic repulsion, thereby avoiding contact between the caressing plate and the color film during reset, causing wrinkles on the caressing plate. In this solution, after the self-test is completed, the caressing plate further removes wrinkles on the color film, thereby improving the accuracy of the color film test and avoiding data deviation caused by color film wrinkles.

[0061] A connecting plate 4 is arranged at the bottom of the fixed plate 3, and a testing device for testing the transparency of the color film is arranged at the bottom of the connecting plate 4. A traction assembly is arranged between the two ends of the movable plate 6 and the corresponding fixed support plate 5. When the squeezing roller 502 contacts the color film, the movable plate 6 is pulled toward the squeezing roller 502 by the traction assembly.

[0062] During the specific implementation, the operator places the color film to be tested on the top of the test bench 1, and then starts the hydraulic telescopic rod 201. The telescopic end of the hydraulic telescopic rod 201 pushes the fixed plate 3 to descend, and the fixed support plate 5 is connected to the sliding support plate 501 by an elastic member. The squeezing rollers 502 between the two sliding support plates 501 descend together, and the two squeezing rollers 502 respectively contact the color film, and then the test device under the connecting plate 4 is irradiated on the control component below for self-testing. The accuracy of the test device is checked by the control component. When the self-test of the test device is completed and the data remains accurate, the fixed plate 3 continues to descend, the sliding support plate 501 remains stationary, and the fixed support plate 5 continues to descend with the fixed plate 3. At this time, the two movable plates 6 are pulled away from each other by the traction component, and the control component is rolled up, so that the test device tests the color film. The test device performs a self-test before each test to ensure the accuracy of the test, avoid data errors caused by failures of the test equipment, and ensure the accuracy of the data.

[0063] Embodiment 2: Figure 4 and Figure 5 As shown, the control components include:

[0066] In specific implementation, when one end of the reference color film 703 is fixedly connected to the movable plate 6, when the movable plate 6 is moved toward the squeezing roller 502 by the action of the traction assembly, the winding roller 7 at one end of the reference color film 703 is rotated by the spring spring 702, and the reference color film 703 is wound around the outside of the winding roller 7 for automatic collection, so that the testing device can smoothly test the color film to be tested. When the movable plate 6 is reset later, the reference color film 703 is unfolded to prepare for the next self-test.

[0067] In this embodiment, Figure 6 , Figure 7 and Figure 8 As shown, the traction assembly includes:

[0068] A fixed slide plate 601, the fixed slide plate 601 is fixedly connected to the outer side of the movable plate 6, the outer side of the fixed slide plate 601 is slidably connected to the limit frame 602, and the limit frame 602 is fixedly connected to the outer side of the sliding support plate 501, for supporting the limit frame 602;

[0069] The second spring 603 is fixedly connected to the outside of the limiting frame 602 , and one end of the second spring 603 is fixedly connected to an end of the fixed slide plate 601 away from the movable plate 6 .

[0070] The traction kit also includes:

[0071] The rack 604 is fixedly connected to the outer side of the sliding support plate 501, and the outer side of the rack 604 is meshedly connected with the first gear 605, and the first gear 605 is rotatably connected to the outer side of the fixed support plate 5;

[0072] The winding disk 606 is fixedly connected to the outside of the first gear 605. A traction rope 607 is wound around the outside of the first gear 605. One end of the traction rope 607 is fixedly connected to the movable plate 6. The outer traction rope 607 is wound and rolled up by the rotation of the winding disk 606, so as to pull the movable plate 6 toward one end of the sliding support plate 501.

[0073] The guide wheel 608 is rotatably connected to the outer side of the sliding support plate 501 and is used to guide and pull the traction rope 607.

[0074] In specific implementation, when 3 descends, the squeezing roller 502 first contacts the color film, and the sliding support plate 501 rises relative to the fixed support plate 5, and the rack 604 fixedly connected to the outside of the sliding support plate 501 drives the meshing first gear 605 to rotate, and the first gear 605 drives the winding disk 606 fixedly connected to the outside to rotate, and the winding disk 606 drives the traction rope 607 fixedly connected to the outside to wind up, and the moving plate 6 drives the fixedly connected fixed slide plate 601 to slide in the limit frame 602 and stretch the second spring 603. When the later stage 3 rises, the second spring 603 is reset and pushes the fixed slide plate 601 to reset.

[0075] Embodiment 3: Fig.11 and Fig.12 As shown, the testing device comprises:

[0076] A gear plate 401, a support rod is fixedly connected to the top of the gear plate 401, the support rod passes through the connecting plate 4 and is rotatably connected to the connecting plate 4, a driving motor is fixedly connected inside the connecting plate 4, and an output shaft of the driving motor supports the rod;

[0077] Two test heads 402 for color filter testing are fixedly connected to the bottom of the gear plate 401 .

[0078] In specific implementation, the color film is tested for transparency through one of the test heads 402 below the test head 402. When the control component is tested, if there is an error in the test data of the test head 402, the drive motor is started, and the output shaft of the drive motor drives the gear plate 401 to rotate. When the gear plate 401 rotates the other test head 402, the test position is tested to ensure the normal operation of the test.

[0079] In this embodiment, Fig.12 As shown, a cleaning component for cleaning the test head 402 is also included, and the cleaning component includes:

[0080] A mounting frame 9, the mounting frame 9 is fixedly connected to the outside of the connecting plate 4, and a transmission rod 901 is rotatably connected inside the mounting frame 9;

[0081] The second gear 902 is fixedly connected to the outside of the transmission rod 901 and meshed with the gear plate 401;

[0082] A rotating ring 904, which is disposed at the bottom end of the mounting frame 9, and is connected to the mounting frame 9 via a torsion spring. A cleaning brush 906 for cleaning the lens of the test head 402 is fixedly connected to the top of the rotating ring 904;

[0083] A third gear 903, which is sleeved on the outside of the transmission rod 901 and connected via a one-way bearing. The outside of the third gear 903 is meshedly connected with a fourth gear 905, which is fixedly connected to the outside of the rotating ring 904;

[0084] The collecting barrel 907 is disposed at the bottom of the mounting frame 9 and below the rotating ring 904 for collecting dust.

[0085] In a specific implementation, when the test head 402 with an error in the test is switched with the rotation of the gear disk 401, the test head 402 rotates to the top of the rotating ring 904, and the gear disk 401 drives the meshing second gear 902 to rotate, the second gear 902 drives the fixedly connected transmission rod 901 to rotate, the transmission rod 901 drives the third gear 903 through the damping effect in the one-way bearing, the third gear 903 drives the meshing fourth gear 905 to rotate, the fourth gear 905 drives the rotating ring 904 to rotate, since the rotating ring 904 is connected to the mounting frame 9 by a torsion spring, the torsion spring accumulates force at this time, when the test lens of the test head 402 is above the rotating ring 904, the torsion spring releases the accumulated force to drive the rotating ring 904 to rotate rapidly, the rotating ring 904 drives the cleaning brush 906 to clean the test head of the test head 402, avoiding manual cleaning, and switching to the detection position after cleaning. If an error still occurs, it means that the test head 402 is faulty, so it is replaced, thereby eliminating the cause of contamination at the test end of the test head 402.

[0086] It is worth noting that the test head 402 is a light transmittance tester or a transmittance tester, which is a device specially used to measure the light transmittance of materials such as color films. This type of equipment can accurately measure the transmittance and refractive index of color films to light of different wavelengths such as visible light, ultraviolet light, infrared light, etc., so as to evaluate the transparency of the color film.

[0087] Embodiment 4: Figure 8 , Fig. 9 and Fig.10 As shown, a caressing plate 8 is provided at the bottom of the movable plate 6, and mounting plates 802 are fixedly connected to both sides of the top of the caressing plate 8, and a first magnetic block 804 is fixedly connected to one side of the mounting plate 802. Limiting grooves 6011 are provided on the outer sides of the two fixed slides 601, and the first magnetic block 804 extends to the inside of the limiting groove 6011 and is slidably connected to the limiting groove 6011. A third spring 807 is fixedly connected between the first magnetic block 804 and the fixed slide 601, and a limiting plate 806 is fixedly connected to the outer side of the limiting frame 602, and a circular groove 8061 is provided on the outer side of the limiting plate 806. One end of the cross plate 803 is fixedly connected to the limiting shaft 805, and the limiting shaft 805 extends to the inside of the circular groove 8061. The first magnetic block 804 is fixedly connected to the outer side of the cross plate 803, and the second magnetic plate 808 is fixedly connected to the outer side of the sliding support plate 501. The second magnetic plate 808 and the first magnetic block 804 magnetically repel each other.

[0088] In specific implementation, during the test of the color film, if the color film has wrinkles or dust on the surface, it will inevitably affect the accuracy of the test. However, it is too cumbersome to remove the wrinkles manually in advance every time. Therefore, in this solution, the squeezing roller 502 between the sliding support plates 501 first contacts the two ends of the color film, and a caressing plate 8 is provided at the bottom of the movable plate 6. The caressing plate 8 contacts the surface of the color film, and the first magnetic block 804 on the top of the caressing plate 8 is driven by the fixed slide plate 601 to move the caressing plate 8 with the movable plate 6. The two caressing plates 8 scrape the surface of the color film to remove the wrinkles on the surface of the color film, and when the fixed slide plate 601 is reset, the limiting shaft 805 at one end of the horizontal plate 803 is in the circular groove 8061 inside the limiting plate 806, so that the limiting shaft 805 moves along the circular groove 8061 opened on the outer side of the limiting plate 806. When the smoothing plate 8 is reset, the smoothing plate 8 does not contact the color film, and the limiting shaft 805 is located at the upper part of the circular groove 8061. In order to ensure that the limiting shaft 805 can smoothly make a circular motion, a second magnetic plate 808 is fixed on the outer side of the sliding support plate 501. When the cross plate 803 moves above the second magnetic plate 808, the limiting shaft 805 moves to the upper part of the circular groove 8061 through the magnetic repulsion, thereby avoiding the smoothing plate 8 from contacting the color film during reset, causing wrinkles on the smoothing plate 8. In this solution, after the self-test is completed, the smoothing plate 8 further removes the wrinkles on the color film, thereby improving the accuracy of the color film test and avoiding data deviation caused by color film wrinkles.

[0089] In this embodiment, Figure 4 and Figure 8 As shown, the elastic member includes a first telescopic rod 503 and a first spring 504 . The first telescopic rod 503 and the first spring 504 are fixedly connected to the fixed support plate 5 and the sliding support plate 501 at both ends respectively, and the first spring 504 is sleeved on the outside of the first telescopic rod 503 .

[0090] A mounting frame 10 is fixedly connected to one side of the movable plate 6, and a plurality of nozzles are arranged on the outside of the mounting frame 10. A foldable airbag 1001 is fixedly connected between the fixed support plate 5 and the sliding support plate 501. A one-way air outlet connecting pipe 1002 is fixedly connected between the foldable airbag 1001 and the mounting frame 10. A one-way air inlet valve is arranged on the outside of the foldable airbag 1001. A dust hood 1003 is fixedly connected between the two sliding support plates 501. A dust pump 1004 is fixedly connected to the top of the fixed plate 3. The suction end of the dust pump 1004 is connected to the dust hood 1003 for absorbing dust.

[0091] During specific implementation, when the smoothing plate 8 removes wrinkles on the surface of the color film, a mounting frame 10 is fixedly connected to one side of the movable plate 6.
