Description

Technical Field

[0001] The present application relates to the technical field of material detection, and in particular to an optical film optical detection device. Background Art

[0002] With the rapid development of optoelectronic technology, optical films are increasingly used in optoelectronic displays, optical communications, optical instruments and other fields. The performance and quality of optical films directly affect the performance and service life of related products. Therefore, it is particularly important to accurately and efficiently detect the optical properties of optical films. The surface flatness of optical films is one of the important indicators for evaluating the production process level of optical films. Traditional optical film detection methods mainly rely on manual operation and are easily affected by human factors, resulting in low accuracy and reliability of detection results. In recent years, with the continuous development of automation technology and intelligent technology, applying these technologies to optical film detection devices to improve detection efficiency and accuracy has become a hot topic in the industry, thereby improving the deficiencies of existing detection device technology.

[0003] The existing technology still has the following problems:

[0004] 1. When using a transmittance meter to test the transmittance of an optical film, there is a lack of a stable limiting mechanism, and the staff often needs to hold the test in hand, which may cause displacement due to hand shaking. This displacement will interfere with the accuracy of the test results, making it impossible for the test data to truly reflect the performance of the optical film. It is also easy for the optical film to be easily sticky with fingerprints and dust. For optical films that have been stored for a long time, dust is more likely to adhere to their surfaces. If they are not cleaned before testing, the light transmittance test of the optical film will be affected.

[0005] 2. The surface flatness of the optical film is crucial to the image quality. If the surface is uneven, it will cause light to scatter and diffract when propagating on the surface of the film, thereby reducing the image quality and clarity. Optical films are mostly very thin films, and surface marks are difficult to observe carefully with the naked eye. Therefore, this method leads to low detection efficiency and poor detection effect when inspecting thin film parts. Ordinary detection equipment is difficult to accurately locate scratches. In addition, the thickness detection error of the optical film is large, so it is difficult to calculate its optical performance based on the thickness of the film layer to ensure that the designed optical film can meet specific application requirements. Summary of the invention

[0006] In order to overcome the lack of a stable limiting mechanism, optical films are prone to fingerprints, dust, etc., and for optical films that have been stored for a long time, dust is more likely to adhere to their surfaces.

When performing optical film inspection, the detection component 4 is first stored and waited until the limit mechanism 37 is cleaned before presenting the detection component 4 on the detection table 311, through The first threaded rod 33 is rotated by the operation of the motor 310, and the rotation of the first threaded rod 33 drives the moving bar 35 to move on the first threaded rod 33, so that the moving bar 35 moves to the first fixed bar 34, and the limiting mechanism 37 is lifted by the operation of the lifting mechanism 39, so that there is a gap between the bottom end of the limiting mechanism 37 and the detection table 311, and the optical film is displayed on the detection table 311 through the limiting frame 31. At the same time, the moving distance of the moving bar 35 can be controlled according to the length of the optical film, and the two ends of the optical film can be fixed, so that the optical film can be smoothly unfolded during cleaning. At this time, the lifting mechanism The structure 39 works to drive the limiting mechanism 37 to contact the detection table 311, and the motor 310 works again to drive the moving bar 35 to slide on the limiting rod 32. The movement of the moving bar 35 drives the adjustment mechanism 36 to move, and the movement of the adjustment mechanism 36 drives the limiting mechanism 37 to move. The limiting mechanism 37 flattens the optical film and cleans the outer surface of the optical film. The adjustment mechanism 36 can be used to adjust the pressure of the limiting mechanism 37 on the optical film to increase a flexible force. The cleaning mechanism 38 is used to collect dust generated when the limiting mechanism 37 is cleaned, so as to facilitate regular cleaning.

[0038] See also Figure 3 , Figure 4 and Figure 5As shown, the adjustment mechanism 36 includes an adjustment seat 361, a first slider 362 is slidably connected to the lower surface of the adjustment seat 361, a driving rod is fixedly installed on the outer surface of the first slider 362, a second threaded rod 363 is rotatably connected to the inner cavity of the adjustment seat 361, the second threaded rod 363 and the first slider 362 are threadedly connected, a first receiving rod 364 is fixedly installed at the four corners of the lower surface of the adjustment seat 361, a telescopic rod 365 is slidably connected to the inner cavity of the first receiving rod 364, an adjustment plate 366 is fixedly installed on the bottom end of the telescopic rod 365, a driving block 367 is fixedly installed on the upper surface of the adjustment plate 366, a driving groove is provided on the outer surface of the driving block 367, the driving rod and the driving groove are slidably connected, a buffer block 368 is slidably connected to the inner cavity of the bottom end of the adjustment plate 366, and a fixing ring 369 is fixedly installed on the bottom end of the buffer block 368. A first spring 3610 is sleeved on the outer surface of the bottom end of the buffer block 368, and the first spring 3610 is located between the adjustment plate 366 and the fixed ring 369. The adjustment seat 361 is fixedly connected to the first fixed bar 34 and the movable bar 35 respectively. The first slider 362 is driven to slide on the adjustment seat 361 by rotating the second threaded rod 363. The sliding of the adjustment seat 361 drives the driving rod to slide on the driving groove on the outer surface of the driving block 367. At this time, the telescopic rod 365 slides in the inner cavity of the first storage rod 364. The sliding of the telescopic rod 365 drives the adjustment plate 366 to move, so that the buffer block 368 drives the fixed ring 369 to move. At this time, the distance from the pressure rod 373 to the detection table 311 can be adjusted, and at the same time, the pressure of the pressure rod 373 on the optical film can be adjusted to achieve flexible clamping of the optical film and avoid damage to the optical film during early clamping.

[0039] See also Figure 6 , Figure 7 and Figure 8As shown, the limiting mechanism 37 includes a pressure block 371, and lifting blocks 372 are fixedly installed at both ends of the pressure block 371. The inner cavity at the bottom end of the pressure block 371 is rotatably connected to a pressure rod 373. The upper surface of the pressure block 371 is fixedly connected to the fixing ring 369, and the bottom end of the pressure rod 373 is in contact with the detection table 311. The cleaning mechanism 38 includes a dust box 381, and the dust box 381 and the pressure block 371 are fixedly connected. The two ends of the dust box 381 are fixedly installed with an insertion rod 382, ​​and the insertion rod 382 is inserted into the pressure block 371 at the moving bar 35. A scraping plate 383 is fixedly installed on one side of the dust box 381, and the scraping plate 383 and the pressure rod 373 are in contact. A dust removal groove 384 is provided on the outer surface of the pressure block 371, and the scraping plate 383 is located in the inner cavity of the dust removal groove 384. The lifting mechanism 39 includes a cylinder 391, the inner cavity of the cylinder 391 is slidably connected with a piston rod 392, one end of the piston rod 392 is fixedly installed with a moving frame 393, and both ends of the moving frame 393 are fixedly installed with lifting bars 394, the upper surface of the lifting bar 394 is inclined, and the upper surface of the bottom end of the lifting bar 394 contacts the top bottom wall of the lifting block 372, and the moving frame 393 is slidably connected with the limiting frame 31. When the moving bar 35 moves to the first fixed bar 34, the operation of the cylinder 391 drives the piston rod 392 to move, and the movement of the piston rod 392 drives the moving frame 393 to slide on the limiting frame 31, and the movement of the moving frame 393 drives the lifting bar 394 to move, and the movement of the lifting bar 394 drives the two lifting blocks 372 on the pressure block 371 to lift up, so that the pressure block 371 is raised as a whole, and there is a gap between the pressure rod 373 and the inspection table 311 at this time, so that the optical film can be passed through the bottom end of the pressure rod 373 during the inspection of the optical film, and the optical film is displayed on the inspection table 311, one end of which is prevented from being directly below the first fixed bar 34, and as the cylinder 391 works again, the lifting bar 394 is separated from the lifting block 372, and one end of the optical film is fixed to the lower part of the pressure rod 373, and at the same time, the motor 310 works to drive the moving bar 35 to move on the first threaded rod 33, and at this time, the pressure rod 373 rolls on the optical film. The pressure rod 373 is made of soft material, and the pressure rod 373 rotates during the movement of the pressure block 371. At this time, the pressure rod 373 can clean the dust on the outer surface of the optical film, and at the same time, it rotates. During the movement, the pressure rod 373 and the scraping plate 383 come into contact, so that the dust on the outer surface of the pressure rod 373 falls from the inner cavity of the dust removal groove 384 into the dust box 381 for centralized collection. The plug rod 382 and the pressure block 371 are separated by plugging and pulling, and the dust on the dust box 381 can be cleaned regularly. At the same time, due to the flexibility and adjustability of the adjustment mechanism 36, it can be adjusted according to optical films of different specifications. That is, when detecting optical films of different thicknesses, the height of the pressure rod 373 can be adjusted to prevent the optical film from being damaged by too much pressure and to prevent the optical film from being uncleanly cleaned due to too little pressure. The flexible rolling cleaning method adopts soft materials and rolling methods, which will not cause scratches or wear on the surface of the optical film. Compared with traditional brushing or wiping methods,Flexible rolling cleaning is more gentle and can maintain the integrity and aesthetics of the optical film surface. The cleaning effect is good. When the pressure rod 373 reaches the other end of the optical film, it stops moving. At this time, the two pressure rods 373 can limit the optical film, which is convenient for subsequent testing and makes the subsequent test data more accurate.

[0040] See also Fig. 9 and Fig.10 As shown, the detection assembly 4 includes a support plate 41, the support plate 41 and the inner cavity of the transmittance meter 1 are movably connected, the upper surface of the support plate 41 is rotatably connected to the second storage rod 42, the inner cavity of the second storage rod 42 is slidably connected to the adjustment rod 43, one end of the adjustment rod 43 is fixedly installed with a connecting strip 44, the end of the connecting strip 44 away from the adjustment rod 43 is fixedly installed with a detection plate 45, the outer surface of the detection plate 45 is provided with a slide groove 46, the inner cavity of the slide groove 46 is slidably connected to the detection mechanism 47, and the upper surface of the detection plate 45 is provided with a A measuring mechanism 48 is arranged, and an alarm mechanism 49 is arranged on the outer surface of the measuring mechanism 48. The slide groove 46, the detection mechanism 47, the measuring mechanism 48 and the alarm mechanism 49 are evenly distributed on the detection plate 45. The outer surface of the detection plate 45 away from the detection mechanism 47 is provided with scale lines, and the middle scale is zero, and increases outward in sequence. After the pressure rod 373 is cleaned, the support plate 41 is pulled to move the support plate 41 on the transmittance meter 1, and the second storage rod 42 is rotated to adjust the angle, so that the connecting strip 44 and The direction of the first fixing bar 34 remains consistent, and the position of the adjusting rod 43 in the inner cavity of the second receiving rod 42 is adjusted. When the bottom end of the detection mechanism 47 contacts the upper surface of the detection platform 311, the positions of the adjusting rod 43 and the second receiving rod 42 are relatively stable. The second receiving rod 42 and the adjusting rod 43 can be fixed by bolts. Since the optical film has a thickness that drives the detection mechanism 47 to move, the thickness of the optical film can be read by the position of the measuring mechanism 48 on the scale line, and the measuring mechanism 48 has a double stroke effect, which is convenient for better reading of data. That is, since the optical film is usually thin and it is inconvenient to read the value, when the measuring mechanism 48 is used to read the data, it is equivalent to the thickness of two optical films superimposed together. In this way, half of the read value is the thickness of the optical film. The flatness of the optical film is detected by the detection mechanism 47. When the detection mechanism 47 encounters a concave or convex part of the optical film, it drives the measuring mechanism 48 to move. The movement of the measuring mechanism 48 drives the alarm mechanism 49 to move, thereby causing the alarm mechanism 49 to issue a warning.

[0041] See also Fig.10 and Fig.11As shown, the detection mechanism 47 includes a detection block 471, the inner cavity of the detection block 471 is slidably connected to an adjustment block 472, the inner cavity of the detection block 471 is rotatably connected to a third threaded rod 473, the bottom end of the adjustment block 472 is fixedly installed with a first connection block 474, the inner cavity of the first connection block 474 is rotatably connected to a detection rod 475, the outer surface of the detection block 471 is fixedly installed with a first fixed block 476, both ends of the first fixed block 476 are fixedly installed with a slide rod 477, and the outer surface of the slide rod 477 is sleeved with The second spring 478, the third threaded rod 473 and the adjustment block 472 are connected by threads, the slide rod 477 and the slide groove 46 are slidably connected, the second spring 478 is located between the detection plate 45 and the first fixed block 476, the bottom end of the second spring 478 is fixedly connected to the first fixed block 476, and the second spring 478 is in a compressed state when the first fixed block 476 is located in the middle of the detection plate 45. The position of the adjustment block 472 in the inner cavity of the detection block 471 can be adjusted by rotating the third threaded rod 473. The movement of 472 drives the first connecting block 474 to move, and the movement of the first connecting block 474 drives the detection rod 475 to move. When measuring the thickness of the optical film, by adjusting the detection rod 475 and the detection platform 311 to fit together, the first fixing block 476 is located in the middle of the detection plate 45. At this time, the bottom end of the pointer 484 points to the zero scale of the optical film. In this way, when the detection rod 475 passes through the optical film, the thickness of the optical film causes the detection rod 475 to rise. At this time, the detection rod 475 drives the detection block 471 to move upward. The upward movement of the detection block 471 drives the first fixed block 476 to move upward, and the upward movement of the first fixed block 476 drives the slide rod 477 to slide in the inner cavity of the slide groove 46. At this time, the second spring 478 is compressed, thereby driving the pointer 484 to move on the scale line, which is convenient for reading the thickness of the optical film. During the detection, one of the detection rods 475 can be brought into contact with the detection table 311 and not in contact with the optical film, so as to ensure that the pointer 484 is always on the zero scale line during the detection, thereby ensuring that the entire equipment is in a relatively stable state during the detection.

The threads at the two ends of the fourth threaded rod 491 are in opposite directions. The second slider 492 is slidably connected to the second fixed bar 481. An indicator light 493 is provided on the outer surface of the second slider 492, and a button 494 is provided on the outer surface of the second slider 492 away from the indicator light 493. The button 494 and the indicator light 493 are electrically connected. A pressure plate 495 is fixedly installed in the middle part of the first slider 482, and the pressure plate 495 is located between the buttons 494. In addition to detecting the thickness of the optical film, the detection mechanism 47 can also detect the flatness of the outer surface of the optical film. When the detection rod 475 encounters a concave and convex part of the outer surface of the optical film, the detection rod 475 is lowered in the concave part under the elastic force of the second spring 478. At the same time, when the detection rod 475 is at the convex part of the optical film, the second spring 478 is compressed and increased. At this time, the detection rod 475 is lifted at the protrusion, which is convenient for accurately finding the optical defect. At the same time, the movement of the detection block 471 drives the pressure plate 495 to move, and the movement of the pressure plate 495 drives the first slide bar 482 to slide on the second fixed bar 481. The movement of the first slide bar 482 drives the belt 486 to move, and the movement of the belt 486 drives the second fixed block 488 and the belt 486 to move. At this time, the rotating rod 485 rotates on the first slide bar 482, and the movement of the belt 486 drives the second connecting block 487 to move. The movement of the connecting block 487 drives the second slide bar 483 to move, so that the moving distance of the second slide bar 483 is twice the moving distance of the detection block 471, that is, the optical film thickness measured by the pointer 484 is twice the actual optical film thickness, so that it is convenient to read data when measuring the film, and at the same time, when there are defects on the outer surface of the optical film, it can be observed more clearly. At the same time, when the pressure plate 495 moves, it will squeeze the button 494, and the squeezing of the button 494 will drive the indicator light 493 to issue a warning, so that the defects of the optical film can be quickly found.At the same time, the second slider 492 can be driven to slide on the second fixing bar 481 by rotating the fourth threaded rod 491, so as to adjust the distance between the second slider 492 and the pressure plate 495. When the outer surface of the optical film reaches the adjusted distance, a reminder is issued according to the needs, so that the staff can find it easily.

[0043] In summary, the optical film is limited by the limiting component 3, and the limiting component 3 can clean the optical film when limiting. The detection component 4 is used to detect the flatness and thickness of the optical film. The light source probe 2 is used to emit light to ensure that the light can accurately irradiate the optical film for light transmittance analysis. When performing optical film detection, the detection component 4 is first stored and waited until the limiting mechanism 37 is cleaned before presenting the detection component 4 on the detection table 311. The moving bar 35 is moved to the first fixed bar 34 through the operation of the motor 310, and the limiting mechanism 37 is lifted by the operation of the lifting mechanism 39 to make the limiting There is a gap between the bottom end of the mechanism 37 and the testing table 311, and the optical film is passed through the limiting frame 31 and displayed on the testing table 311. At this time, the lifting mechanism 39 works to drive the limiting mechanism 37 to contact the testing table 311, and the motor 310 works again to drive the moving bar 35 to slide on the limiting rod 32. The movement of the moving bar 35 drives the adjustment mechanism 36 to move, and the movement of the adjustment mechanism 36 drives the limiting mechanism 37 to move. The limiting mechanism 37 flattens the optical film and cleans the outer surface of the optical film. The adjustment mechanism 36 can be used to adjust the pressure of the limiting mechanism 37 on the optical film to increase a flexible force. The cleaning mechanism 38 is used to collect The dust generated when the limit mechanism 37 is cleaned is convenient for regular cleaning. After the pressure rod 373 is cleaned, the support plate 41 is pulled to move the support plate 41 on the transmittance meter 1, and the second storage rod 42 is rotated to adjust the angle so that the connection strip 44 and the first fixing strip 34 are in the same direction, and the position of the adjustment rod 43 in the inner cavity of the second storage rod 42 is adjusted. When the bottom end of the detection mechanism 47 contacts the upper surface of the detection table 311, the position of the adjustment rod 43 and the second storage rod 42 is relatively stable. The second storage rod 42 and the adjustment rod 43 can be fixed by bolts. Since the optical film has a thickness that drives the detection mechanism When the measuring mechanism 48 moves, the thickness of the optical film can be read by the position of the measuring mechanism 48 on the scale line, and the measuring mechanism 48 has a double stroke effect, which is convenient for better reading of data. That is, since optical films are usually thin, it is inconvenient to read the values. When the measuring mechanism 48 is used to read the data, it is equivalent to the thickness of two optical films superimposed together. In this way, half of the read value is the thickness of the optical film. The flatness of the optical film is detected by the detection mechanism 47. When the detection mechanism 47 encounters a concave or convex part of the optical film, it drives the measuring mechanism 48 to move. The alarm mechanism 49 is used to issue a warning when unevenness appears on the outer surface of the optical film.
