Technical Field
[0001] The utility model provides a flatness detector, belonging to the technical field of AF coating for cover glass, and particularly relates to a flatness detector for the surface of AF coating on cover glass. Background Art
[0002] AF coating, fully known as Anti-fingerprint coating, is a special chemical material layer coated on the surface of glass or other transparent materials. Its main functions are to provide anti-fouling, anti-fingerprint, and anti-oil pollution capabilities, while maintaining the cleanliness and transparency of the materials. This coating technology is usually applied to glass display screens of mobile phones, tablet computers, TVs, LEDs, etc., and other occasions that require anti-fouling and easy cleaning. The flatness test of AF coating is crucial because it directly affects the optical performance, wear resistance, and anti-fouling effect of the materials. An uneven film layer may cause uneven light refraction, affecting visual clarity, and reducing the durability and aesthetics of the product. Regular testing ensures product quality and meets consumers' demands for high-performance display devices.
[0003] Currently, the surface flatness detection of AF coating mainly relies on a machine vision-based detection system. However, the purchase and maintenance costs of such high-precision vision detection equipment are relatively high, and it is difficult to achieve real-time detection on the production line, which limits its application in large-scale manufacturing processes. Summary of the Utility Model
[0004] Embodiments of this application are to make up for the deficiencies of the prior art. By providing a flatness detector for the surface of AF coating on cover glass, the problem of excessively high detection cost for the flatness of AF film in the prior art is solved.
[0005] To solve the above technical problems, the utility model provides the following technical solutions: A flatness detector for the surface of AF coating on cover glass, including an outer housing. Inside the outer housing, there are several uniformly and juxtaposed adjustment structures. On one side of the outer housing, there is a detection plate that penetrates through the body on one side of the outer housing and is placed on one side of the adjustment structure. On one side of the detection plate, there is a recording pen that is in close contact with and corresponds to the detection plate. Below the recording pen, there is an adjustment rod fixedly connected.
[0006] Preferably: A connecting rod corresponding to the adjustment rod is sleeved outside the recording pen. The recording pen penetrates through the connecting rod, and at the end of the recording pen away from the detection plate, there is a collar corresponding to the diameter of the connecting rod.
[0007] Preferably: The end of the adjustment rod away from the connecting rod is fixedly connected with a contact member. On the outer circle of one side of the contact member close to the adjustment rod, there is an inclined surface. The outside of the contact member is sleeved with a protective sleeve corresponding to itself and the inclined surface.
[0008] Preferably, a return spring sleeving the outside of the adjusting rod is arranged above the contact member, and the other end of the return spring is provided with a sliding groove disposed inside the outer housing.
[0009] Preferably, the sliding groove is internally provided with storage grooves evenly distributed and embedded in the outer housing. A ball is movably connected in each storage groove, and the ball is in close contact with the outer wall of the adjusting rod.
[0010] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:
[0011] The present utility model adjusts the position of the adjusting rod by providing an adjusting structure disposed inside the outer housing, thereby driving the recording pen correspondingly connected to itself to move.

[0023] 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 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.
[0024] It should be noted that the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.
[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs; the terms used in the specification of the present utility model herein are only for the purpose of describing specific implementation manners and are not intended to limit the present utility model; the term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0026] As Figure 1 and Figure 2 shown, one end of the adjusting rod 21 away from the connecting rod 13 is fixedly connected with a contact member 22. An inclined surface 23 is provided on the outer circumference of one side of the contact member 22 close to the adjusting rod 21. A protective sleeve 24 corresponding to itself and the inclined surface 23 is sleeved outside the contact member 22. A return spring 25 sleeved outside the adjusting rod 21 is provided above the contact member 12, and the other end of the return spring 25 is provided with a sliding groove 15 arranged inside the outer housing 1. By providing an adjusting structure 2 arranged inside the outer housing 1, the position of the adjusting rod 21 is adjusted, so as to drive the recording pen 12 connected correspondingly to itself to move. The recording pen 12 contacts the detection plate 11, so as to record its own position change. By observing the recorded data on the detection plate 11, the flatness can be judged.
[0027] In this implementation manner, in the flatness detector for the AF coating surface of the cover glass, the adjusting mechanism 2 integrated inside the outer housing 1 acts as a fine-tuning mechanism, and its main function is to precisely control the vertical displacement of the adjusting rod 21. The displacement of the adjusting rod 21 is transmitted through the recording pen 12 mechanically coupled with it, so that the recording pen 12 can perform contact tracing on the detection plate 11, thereby leaving a physical trace of the position change on the detection plate. By carefully analyzing the trace on the detection plate 11, the flatness of the AF coating surface can be accurately evaluated.
[0028] As Figure 3 , 4 , as shown in Figure 5, a flatness detector for the AF coating surface of cover glass includes a housing 1. Inside the housing 1, there are several uniformly and juxtaposed adjustment structures 2. On the housing 1, there is a detection plate 11 that penetrates through one side body of itself and is placed on one side of the adjustment structure 2. On one side of the detection plate 11, there is a recording pen 12 that is in close contact with and corresponds to itself. Below the recording pen 12, there is an adjustment rod 21 fixedly connected. A connecting rod 13 corresponding to the adjustment rod 21 is sleeved outside the recording pen 12. The recording pen 12 penetrates through the connecting rod 13. At one end of the recording pen 12 away from the detection plate 11, there is a collar 14 corresponding to the diameter of the connecting rod 13. The adjustment rod 21 is in the sliding groove 15. With the help of the ball 27, the contact friction is reduced, which is beneficial to the up and down sliding of the adjustment rod 21; the protective sleeve 24 not only protects the contact part 22, but also protects the AF film itself. It should be noted that the recording pen can be a simple writing pen, and the detection plate 11 is a simple recording paper or plate. For more accurate and real-time operations, the recording pen 12 can be replaced with an electromagnetic pen. The detection plate 11 records the position of the recording pen 12 according to the current change of the recording pen 12 and saves the data log to adapt to the intelligent production line.
[0029] In this implementation scheme, the movement of the adjustment rod 21 in the sliding groove 15 is realized by the ball 27 embedded in the groove. This ball guiding mechanism significantly reduces the friction coefficient between the adjustment rod and the sliding groove, ensuring the smooth and precise vertical movement of the adjustment rod 21. The design of the protective sleeve 24 not only provides physical protection for the contact part 22, avoiding potential mechanical damage, but also forms a protective barrier for the AF film, preventing possible film layer damage during the detection process. In addition, the recording pen 12 can be selected as a traditional writing tool or a high-precision electromagnetic pen according to needs. The latter can interact with the induction element on the detection plate 11, record and digitize its position information in real time, and then save it as an electronic data log through the data acquisition system for subsequent data analysis and processing to meet the requirements of modern intelligent manufacturing for automation and data-driven.
[0030] When in use:
[0031] 1. Equipment assembly and calibration:
[0032] Ensure that all components including the housing 1, the adjustment structure 2, the adjustment rod 21, the contact part 22, the protective sleeve 24, the return spring 25, the sliding groove 15, the detection plate 11 and the recording pen 12 are correctly installed.
[0033] Install the recording pen 12 on the connecting rod 13 and ensure that the collar 14 is fixed in place.
[0034] Adjust the tension of the return spring 25 to ensure that the adjustment rod 21 can move freely in the sliding groove 15.
[0035] 2. Equipment Preheating and Initialization:
[0036] Start the equipment and preheat it to ensure that all mechanical components can operate smoothly.
[0037] If the electromagnetic pen 12 and the electronic detection board 11 are used, perform system initialization, including calibrating the sensitivity of the electromagnetic pen and the response threshold of the detection board.
[0038] 3. Sample Preparation:
[0039] Place the cover glass AF coating to be detected in the detection area, ensuring good contact between its surface and the detection board 11.
[0040] 4. Detection Process:
[0041] Adjust the position of the adjusting rod 21 through the adjusting structure 2 so that the contact member 22 contacts the AF coating surface.
[0042] Start the recording pen 12 and begin to record the position changes of the contact points on the detection board 11.
[0043] Reduce the friction through the ball 27 and move the adjusting rod 21 manually or automatically to make the recording pen 12 perform contact tracing on the detection board 11.
[0044] 5. Data Recording and Analysis:
[0045] If a traditional writing pen is used, directly observe the traces on the detection board 11 and record the position changes.
[0046] If an electromagnetic pen and an electronic detection board are used, the system will automatically record and digitize the position information and save it as a data log.
[0047] 6. Flatness Evaluation:
[0048] Analyze the data on the detection board 11 to evaluate the flatness of the AF coating surface. For manual recording, it may be necessary to convert the data into charts or curves for analysis.
[0049] For the automatically recorded data, use professional software for analysis to obtain more accurate flatness evaluation results.
[0050] 7. Result Output:
[0051] Output the analysis results as a report for quality control or further research use.
[0052] 8. Equipment Cleaning and Maintenance:
[0053] After the detection is completed, clean the equipment, especially the protective cover 24 and the detection board 11, to ensure that there are no residues affecting the next detection.
[0054] Maintain the equipment regularly, check the wear conditions of the ball bearings 27 and the sliding grooves 15, and replace them if necessary.
