Description

Technical Field

[0001] This utility model relates to the field of testing instruments, specifically an array substrate end face testing instrument. Background Technology

[0002] In the current era of continuous development in display technology, the quality of the array substrate, as a core component of various display devices, directly affects the overall performance and lifespan of the display device. The polarizer, as an indispensable key component of the array substrate, has a significant impact on the optical performance and stability of the entire array substrate due to the microscopic quality of its end face, especially the presence of defects such as cracks. Currently, array substrate end face testers are used in the market to detect cracks in polarizers. An array substrate end face tester is a precision instrument specifically designed to detect the microscopic quality of the polarizer end face in an array substrate. Its core function is to achieve accurate observation and detection of defects such as microscopic cracks on the polarizer end face through the coordinated work of a series of optical components and mechanical structures, providing crucial technical support for the quality control of array substrates.

[0003] Existing array substrate end-face testers primarily use adjustment components to adjust the position and height of polarizer placement, typically relying on friction to maintain the slider's position. The adjustment component usually includes a fixed top mount and a sliding slider. The slider achieves positional fixation through friction generated by direct contact with the fixed top mount. However, this design suffers from the following problems: over time and with frequent use, components of the adjustment component (such as the slider and fixed top mount) wear down. This wear reduces the roughness of the contact surfaces, thereby decreasing friction. For example, the contact surface between the slider and the fixed top mount becomes smooth after repeated sliding, significantly reducing friction. When friction decreases to a certain level, the slider may fail to maintain its position, especially under external vibration or minor impact. In this case, the slider may shift, leading to a loss of adjustment accuracy. For example, during testing, if the slider suddenly slides, it can cause the stage to shift, affecting the accuracy of the test results. Once friction decreases due to wear, adjustment accuracy becomes difficult to guarantee. This not only affects the repeatability and reliability of the test but may also lead to deviations in the test data, impacting the accurate assessment of polarizer quality. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides an array substrate end face tester, which can effectively solve the technical problem that the adjustment components of existing testers suffer from reduced friction due to long-term wear, resulting in slider failure and reduced adjustment accuracy.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] The following is combined Figures 1-5 The array substrate end face tester of this utility model is described in detail as follows:

[0020] An array substrate end-face tester includes a support 1, an objective lens assembly 2, an optical transmission assembly 3, and an imaging display assembly 4. The support 1 includes a base 5 and a support column 7 disposed on the top surface of the base 5. The support column 7 is equipped with an adjustment assembly 21, which includes a fixed top seat 8 fixedly disposed on the support column 7 and a slidable slider 9. One end of the fixed top seat 8 is recessed inward to form a slot 14. A rotatable adjustment knob 13 is disposed on the side of the fixed top seat 8. One end of the adjustment knob 13 is equipped with a gear 17, which is disposed in the slot 14. The fixed top seat 8... A sliding part 16 is formed outward from the side of the fixed top seat 8. A groove 15 is formed between the surface of the fixed top seat 8 and the sliding part 16. A plurality of fixed teeth 18 are formed outward from the surface of the slider 9. The plurality of fixed teeth 18 are arranged at equal intervals on the slider 9. The toothed disc 17 is engaged with the fixed teeth 18. A fixed groove 19 for sliding connection with the sliding part 16 is formed inward from the surface of the slider 9. A snap-fit ​​part 20 for sliding connection with the groove 15 is formed outward from the surface of the slider 9. When the adjustment knob 13 is adjusted, the slider 9 moves along the vertical direction of the fixed top seat 8.

[0021] One end of the slider 9 is provided with a stage 10 for placing the polarizer to be tested. The surface of the stage 10 is recessed inward to form a placement groove 11, and the surface of the stage 10 protrudes outward to form a locking part 12 for locking the polarizer. The stage 10 at one end of the slider 9 provides a stable placement platform for the polarizer to be tested. The placement groove 11 and locking part 12 of the stage 10 can ensure that the polarizer remains fixed during the test and prevent inaccurate test results due to the movement of the polarizer.

[0022] The lower surface of the base 5 is provided with an anti-slip and shock-absorbing pad 6, which is made of rubber. This effectively prevents the tester from shifting due to vibration during use, and also reduces the impact of external vibration on the test results, reduces the interference of external vibration on the acquisition and observation of microscopic images, and ensures the accuracy of the test.

[0023] The objective lens assembly 2 faces the upper surface of the stage 10 and is used to acquire a microscopic optical image of the polarizer to be tested. The optical transmission assembly 3 is connected to the objective lens assembly 2 and is used to transmit the optical image acquired by the objective lens assembly 2, ensuring stable image transmission. A support platform 22 is provided on the top surface of the base 5. The support platform 22 is provided with a rotatable rotating component 23 and a rotatable connecting rod 24. The connecting rod 24 is rotatably connected to the support platform 22 through the rotating component 23. A fixing flange 25 is provided at the top of the connecting rod 24. One end of the objective lens assembly 2 is connected to the top of the connecting rod 24 through the fixing flange 25. The connection between the objective lens assembly 2 and the optical transmission assembly 3, through the cooperation of the support platform 22, the rotating component 23, and the connecting rod 24, achieves stable support and angle adjustment of the objective lens assembly 2, allowing the angle of the objective lens to be adjusted as needed, thus enhancing the flexibility and adaptability of the testing instrument.

[0024] The imaging display component 4 is located on the base 5. It converts optical images into electrical signals, receives and processes these signals, and displays the imaging results to assist inspectors in observing the microscopic details of the polarizer. The imaging display component 4 includes a fixing rod 26 and a display screen 28. The fixing rod 26 is located on the top surface of the base 5 and is equipped with a rotation adjustment component 27. The display screen 28 is mounted on the fixing rod 26 via the rotation adjustment component 27. The fixing rod 26 and the rotation adjustment component 27 allow the display screen 28 to be flexibly adjusted in height, facilitating observation of the imaging results from different heights by inspectors. The imaging display component 4 converts optical images into electrical signals and displays the imaging results, assisting inspectors in observing the microscopic details of the polarizer more clearly, thus improving the accuracy and efficiency of the inspection. The display screen 28 is also equipped with a control switch and adjustment keys.

[0025] In this embodiment, the objective lens assembly 2 is used to acquire microscopic optical images of the object to be tested. It can magnify and image the microstructures such as vertical cracks and horizontal cracks generated by cutting an LCD on the surface of a polarizer. The optical transmission assembly 3 is used to transmit the optical images acquired by the objective lens assembly 2, which can ensure stable image transmission. Through the imaging display assembly 4, the cutting effect such as the depth of vertical cracks and the condition of horizontal cracks on the cutting end face can be determined.

[0026] The array substrate end face tester of this embodiment uses a slider 9 that moves up and down along a fixed top seat 8. The gear 17 of the adjusting knob 13 engages with the fixed teeth 18, the sliding part 16 slides between the slider and the fixed groove 19, and the snap-fit ​​part 20 slides between the snap-fit ​​part and the sliding groove 15. This ensures a tight fit between the slider 9 and the fixed top seat 8. The fixed teeth 18 on the slider 9 increase the contact area between the slider 9 and the fixed top seat 8, greatly increasing friction and making the connection between the gear 17 and the fixed teeth 18 more stable. This allows for precise adjustment of the stage 10, ensuring accurate vertical movement of the slider 9, significantly improving the adjustment accuracy and stability of the tester, and making the testing process more convenient and efficient.

[0027] In practical use, firstly, the polarizer to be tested is placed in the placement slot 11 of the stage 10, and the polarizer is fixed by the locking part 12 of the stage 10 to prevent it from moving during the test. Then, by rotating the rotating part 23 and the connecting rod 24 on the support stage 22, the angle of the objective lens assembly 2 is adjusted so that the objective lens assembly 2 is accurately aligned with the polarizer on the stage 10. If it is necessary to fine-tune the height of the stage 10, the adjustment knob 13 can be rotated. Under the meshing transmission of the gear plate 17 and the fixed gear 18, and the sliding cooperation of the sliding part 16 and the fixed slot 19, and the locking part 20 and the sliding groove 15, the slider 9 drives the stage 10 to move precisely along the vertical direction of the fixed top seat 8 until the polarizer is in the optimal observation position of the objective lens assembly 2. Then, the objective lens assembly 2 starts to work. It can perform microscopic imaging on the end face of the polarizer, obtain a microscopic optical image of the polarizer, and especially magnify and image any defects such as cracks that may exist, making microscopic cracks that are originally difficult to detect with the naked eye visible. Subsequently, the microscopic optical image acquired by the objective lens assembly 2 is transmitted through the optical transmission assembly 3, which ensures that the image signal is transmitted stably and without distortion to the imaging display assembly 4. Upon receiving the optical image transmitted by the optical transmission assembly 3, the imaging display assembly 4 converts the optical image into an electrical signal, processes the electrical signal, and converts the processed signal into a visualized image, which is then displayed on the display screen 28. By observing the imaging results displayed on the display screen 28, the inspector can clearly observe the microscopic details of the polarizer, thereby accurately determining whether there are defects such as cracks on the end face of the polarizer. Specifically, the working process and principle of the objective lens assembly 2, optical transmission assembly 3, and imaging display assembly 4 for magnifying and imaging the polarizer and detecting cracks in the polarizer are all known to those skilled in the art and will not be described in detail here.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
