Description

Technical Field

[0001] The present invention relates to the technical field of material property detection, and particularly to a permeability detection device dedicated to color films. Background Art

[0002] As a key basic material in fields such as display panels, optical devices, and packaging materials, the permeability of color films directly determines core indicators such as the optical properties, barrier properties, and service life of products. In the display field, permeability parameters such as the light transmittance and scattering rate of color films have an important impact on the brightness uniformity and color reproduction of display screens; in the packaging field, the barrier ability of color films to gases and liquids, that is, the gas and liquid permeability, is related to the shelf life and quality stability of the packaged contents. Therefore, accurate detection of the permeability of color films is an important link to ensure product quality and promote the development of related industries.

[0003] Currently, most of the existing color film permeability detection devices can only indirectly calculate the permeability index of color films by measuring physical parameters such as pressure and flow rate, and it is difficult to intuitively present the changes in the pore structure of color films during the detection process. For example, traditional differential pressure type permeability detection devices can calculate the permeability of color films by detecting the flow rate and pressure difference of the detection medium, but they cannot observe the flow state of the detection medium in the pores of the color film, nor can they judge whether there is blockage in the pores or whether the pore structure deforms due to pressure changes. Although optical detection devices can obtain optical characteristic data of color films to a certain extent, they lack dynamic visualization detection means for the microscopic structure of pores and it is difficult to establish an intuitive connection between optical data and pore structure changes. In addition, even if some devices have a simple imaging function, the imaging clarity and magnification are limited, and they cannot meet the detection requirements for the fine structure of color film pores, resulting in operators being difficult to comprehensively and accurately evaluate the permeability and quality status of color films.

[0023] The microscopic imaging visualization mechanism 3 further includes a trapezoidal slide bar 310. The trapezoidal slide bar 310 is slidably connected to the trapezoidal chute 39. The trapezoidal slide bar 310 is of the same length as the trapezoidal chute 39. At both ends of the side of the trapezoidal slide bar 310 away from the trapezoidal chute 39, a rack group 311 is fixedly connected. A connecting column is arranged in the middle of the rack group 311 and is fixedly connected to the extending end of the electric control telescopic rod 36. At both ends of the rack group 311, an L-shaped connecting rod 312 is fixedly connected. The end of the L-shaped connecting rod 312 away from the rack group 311 is fixedly connected to a control body 313.

In each group of bearing seats 37, a limiting rod 316 is clamped. At both ends of the limiting rod 316, a semi-gear 317 is fixedly connected.

The semi-gear 317 is meshed and connected with the rack group 311. The semi-gear 317 is a gear provided with a semi-circle of tooth blocks. An outer ring of the limiting rod 316 is provided with a positioning plate 318. The two ends of the positioning plate 318 are respectively fixedly connected to the two limiting rods 316. A reflecting mirror 319 is fixedly connected to the middle of the side of the positioning plate 318 away from the limiting rod 316. The reflecting mirror 319 is mainly used for reflecting the light source of the light source body 31 to the color film positioned by the positioning body 32.

[0024] The working principle of all the contents in the above embodiments is as follows: In the initial state: The two control bodies 313 respectively clamp the two limiting rods 316 in the bearing seats 37, and the reflecting mirror 319 is parallel to the top surface of the test instrument 1.

[0025] The following is the working process of the height adjustment mechanism 2 for axially adjusting the position of the reflecting mirror 319 to adapt to color films with different subsequent requirements: When in use, according to the sizes of different color films to be detected, start the power supply of the screw rod 22. The driving shaft of the power supply drives it to rotate forward or backward. When the screw rod 22 rotates forward, the adjusting seat 23 threadedly connected with it, under the meshing action of the screw rod 22, the adjusting seat 23 cooperating with the screw rod 22 will move vertically downward along the axis of the screw rod 22, thereby controlling the reflecting mirror 319 to descend. With the cooperation of the two screw rods 22, the vertical movement stability of the adjusting seat 23 is assisted. On the contrary, if the screw rod 22 rotates backward, the adjusting seat 23 is controlled to move vertically upward, thereby controlling the reflecting mirror 319 to rise.

[0026] Through the setting of the height adjustment mechanism 2, under the driving of the forward and reverse rotation of the screw rod 22, the height of the reflector 319 in the vertical direction can be adjusted, so as to flexibly adapt to color film samples of different thicknesses. In actual detection, there are differences in the thickness of the color film. By adjusting the height of the reflector 319, the light propagation path can be accurately changed to ensure that the light can always irradiate the pores of the color film at the best angle and be effectively reflected onto the microscopic imaging module 33, avoiding the problem that the light cannot be accurately focused and imaged due to the change of the color film thickness, ensuring the stability and effectiveness of the light transmission during the detection process, improving the compatibility and detection versatility of the equipment for diverse color film samples. At the same time, the height adjustment can optimize the distribution of light inside the equipment, reduce light loss, and further improve the imaging quality, enabling the operator to obtain clearer and more accurate pore images, thereby more reliably judging the permeability and pore structure state of the color film.

[0027] Please refer to the above working process Figures 1 to 4 。

[0028] The following is the working process of the microscopic imaging visualization mechanism 3 that visualizes the pores of the color film during detection and simulates the detection under different light source conditions: During use, the light source body 31 is connected to an external drive source to start. After its light source emits along a straight line, it directly irradiates the surface of the color film. The light undergoes optical phenomena such as refraction, scattering, and reflection in the pore area of the color film, carrying the microscopic structure information of the pore surface. At this time, the reflector 319 located above the color film plays a role. Its initial angle is preset to be parallel to the top surface of the test instrument 1. The surface of the reflector 319 is coated with a high-reflectivity coating material, which can efficiently reflect light, so as to reflect the light reflected from the surface of the color film a second time, change the light propagation direction, and make it ready to be projected onto the microscopic imaging module 33 on the other side, thereby enabling the operator to visually understand the pore surface of the color film during detection.

[0029] After the light enters the microscopic imaging module 33, it is first preliminarily converged by the front optical lens group to improve the light concentration. Then, the light enters the microscopic objective lens with high magnification and high resolution in the microscopic imaging module 33. This objective lens can adjust the focal length within a certain range according to the detection requirements to achieve magnified imaging of the color film pores at different multiples. The imaging light is then projected onto a highly sensitive image sensor. The image sensor converts the optical signal into an electrical signal and transmits the signal to the data processing unit of the device through a high-speed data transmission line. During the imaging process, the operator can manually or automatically adjust the focal length and magnification of the microscopic imaging module 33 through the device operation interface, combined with the fine adjustment of the angle of the adjustable-angle reflector 319, to achieve high-magnification and clear magnified imaging of the color film pores, and can clearly present the fine structure of the pores, such as the shape, size, edge contour of the pores, and the connection situation between the pores, etc.

[0030] Furthermore, according to the detection requirements, the reflection angle of the reflector 319 can be adjusted, and then the detection results of the color film under different environments can be simulated. During the detection, the two electric control telescopic rods 36 contract under the control of an external controller. When the electric control telescopic rod 36 contracts, since it is fixedly connected to the trapezoidal slide bar 310, when the electric control telescopic rod 36 contracts, it pulls the trapezoidal slide bar 310 to slide straight in the trapezoidal chute 39 in the direction of the contraction of the electric control telescopic rod 36, thereby driving the rack group 311 on the trapezoidal slide bar 310 to move synchronously. At the same time, the movement of the trapezoidal slide bar 310 pulls the L-shaped connecting rod 312 on the side away from the electric control telescopic rod 36 to approach the electric control telescopic rod 36, and then the movement of the L-shaped connecting rod 312 pulls the control body 313 to slide in the limit groove body 38 towards the auxiliary block 314, so as to limit the electric control telescopic rod 36 clamped in the bearing seat 37. And the control body 313 on the other side, in this state, through the transmission of the central control rod 315, when one control body 313 approaches the auxiliary block 314, it pushes the central control rod 315 and then controls the other control body 313 to move in the direction away from the auxiliary block 314, thereby releasing the restriction on the other limiting rod 316. Then, during the continuous movement of the rack group 311, the semi-gear 317 on the side where the control body 313 restricts the movement of the limiting rod 316 meshes with the rack group 311 and drives to deflect. During the rotation of the semi-gear 317, the positioning plate 318 deflects forward with the connection line between the limiting rod 316 and the bearing seat 37 as the fulcrum, so as to adjust the angle of the reflector 319 through the deflection of the positioning plate 318.

[0031] On the contrary, if the electric control telescopic rod 36 extends, contrary to the above working process, it controls the reflector 319 to perform a reverse deflection movement with the other limiting rod 316 as the axis, so as to simulate the detection of the color film pores under different light environments and better visually observe the pore state.

[0032] Through the setting of the microscopic imaging module 33, an intuitive and high-resolution observation method is provided for the detection of color film pores. Through high-magnification imaging, the fine structure of the pores can be clearly presented, such as the shape, size, edge contour of the pores, and the connectivity between the pores, etc. The operator can observe the dynamic changes of the color film pores under the action of the detection medium in real time, such as whether the medium blocks the pores and whether the pore structure deforms due to pressure changes, etc., so as to conduct a more comprehensive and in-depth evaluation of the permeability of the color film, combine visual observation with quantitative analysis, and provide better data support for the quality detection of the color film.

[0033] Through the coordinated use of multiple structures, under the telescopic control of the electric control telescopic rod 36, the deflection angle of the reflector 319 is adjusted, so that the light adjustment is more flexible. According to the optical characteristics and detection requirements of different color films, the incident and reflection angles of light can be accurately adjusted. This helps to obtain the best light reflection effect, ensure that the light can completely capture the optical information of the color film pore area, and accurately transmit it to the microscopic imaging module 33, avoiding imaging blurring or information loss caused by poor light angles. By changing the angle of the reflector 319, the color film pores can also be observed from multiple perspectives, obtaining more comprehensive pore structure information, which helps to discover the subtle differences and potential problems of the pores at different angles. In addition, during the detection process, if the light reflection is affected by a small offset of the sample position or other factors, the angle of the reflector 319 can be adjusted in time for compensation, ensuring the continuity and accuracy of the detection, and enhancing the adaptability and stability of the equipment in complex detection scenarios.
