Description

Technical Field

[0001] This invention relates to the field of glass substrate inspection equipment technology, and more specifically to a glass substrate defect detection device. Background Technology

[0002] As a core material for display devices such as LCDs and OLEDs, the surface flatness and scratches of glass substrates directly determine the imaging quality and lifespan of these devices. Glass substrate defect detection equipment is a key piece of equipment in the display device manufacturing process. It is mainly used to detect surface scratches, flatness, and other defects on processed glass substrates. By accurately identifying and marking the location of defects, it provides a basis for subsequent sorting, repair, or scrapping. It is a crucial link in ensuring the yield rate of display device products and plays an irreplaceable role in the fields of electronics, information technology, and display manufacturing.

[0003] Currently, the technical means of existing glass substrate defect detection devices are mainly divided into two categories: manual inspection and semi-automatic inspection. Manual inspection relies on workers to observe the substrate surface visually or with the help of simple magnification tools, and judge whether there are defects such as scratches based on experience. Some devices are equipped with simple lighting devices to improve the visibility of defects. Semi-automatic inspection equipment uses industrial cameras to collect images of the substrate surface and combines image analysis technology to identify defects.

[0040] Example

[0041] To address the technical problems in the background art, the following glass substrate defect detection device is provided:

[0042] Combination Figures 1-10 As shown, the glass substrate defect detection device provided by the present invention includes:

[0043] Support frame 1;

[0044] The testing platform 2 is fixedly installed on the support frame 1. A clearance hole 21 is provided in the middle of the testing platform 2, and a support component 22 is installed on the testing platform 2 and located in the clearance hole 21.

[0045] The slide rail 3 is fixedly installed on the top of the support frame 1 and located below the detection platform 2. A sliding block 31 is slidably installed on the slide rail 3 in a horizontal direction. An electric slider connected to the sliding block 31 is fixedly installed on the slide rail 3. A transfer component 32 that can move through the clearance hole 21 is symmetrically fixedly installed on the top of the sliding block 31. When one set of transfer components 32 is located directly below the clearance hole 21, the other set of transfer components 32 is located on one side of the detection platform 2.

[0046] The scratch detection component 4 is mounted on the support frame 1 and located directly above the clearance hole 21. The scratch detection component 4 is used to detect scratches on the glass surface.

[0047] Translation mechanism 5 is installed on the detection platform 2 and located on one side of the clearance hole 21. The movable end of translation mechanism 5 is equipped with marking component 6, which is used to mark the scratches on the glass surface.

[0048] The sealing mechanism 7 is installed at the bottom of the detection platform 2. The sealing mechanism 7 is used to seal or unseal the bottom of the clearance hole 21.

[0049] When inspecting the glass substrate, the clearance hole 21 of the inspection platform 2 provides space for substrate transfer and inspection, and the support component 22 stably supports the substrate; the two sets of transfer components 32 respectively meet the needs of loading and unloading operations, without the need for manual intervention, thus improving inspection efficiency; the scratch detection component 4 accurately detects scratches on the substrate, and the translation mechanism 5 drives the marking component 6 to quickly mark the defect location, which is convenient for subsequent sorting and processing.

[0050] Combination Figures 1-10 As shown, the supporting component 22 includes a fixed frame 221, a telescopic rod 222, a supporting block 223, and a driving rod 224. Both sides of the detection platform 2 have through holes communicating with the clearance holes 21. Fixed frames 221 are fixedly installed on both sides of the detection platform 2, located outside the through holes. Horizontally oriented telescopic rods 222 are symmetrically fixedly installed on the fixed frames 221. The telescopic ends of the two telescopic rods 222 extend through the through holes into the clearance holes 21 and are fixedly connected to the supporting blocks 223. A driving rod 224, fixedly connected to the supporting blocks 223, is fixedly installed on the fixed frame 221. In use, the driving rod 224 drives the supporting blocks 223 to move horizontally along the telescopic rods 222. The spacing can be adjusted according to the substrate size to adapt to the support requirements of substrates of different specifications. Furthermore, the horizontal telescopic adjustment ensures accurate substrate positioning, avoids displacement during transfer, and improves detection accuracy.

[0051] Combination Figures 1-10 As shown, the transfer component 32 includes a second telescopic rod 321, a bracket 322, and a second drive rod 323. The top of the sliding block 31 is fixedly mounted with vertically oriented second telescopic rods 321 in a rectangular array. The top of the four second telescopic rods 321 is fixedly mounted with a bracket 322 that can movably pass through the clearance hole 21. The top of the sliding block 31 is fixedly mounted with a drive rod 323 connected to the bracket 322. In use, the four second telescopic rods 321 of the transfer component 32 support the bracket 322 in a rectangular array, and work with the drive rod 323 to achieve smooth lifting and lowering.

[0052] Combination Figures 1-10As shown, the scratch detection component 4 includes a supplementary light plate 41, an industrial camera 42, and a display screen 43. The supplementary light plate 41 is symmetrically fixed on the support frame 1, directly above the clearance hole 21. The supplementary light plate 41 emits a blue light source when working. The industrial camera 42 is fixedly fixed on the support frame 1, symmetrically positioned between the two supplementary light plates 41. The display screen 43 is fixedly fixed on the top of the detection platform 2, to one side of the clearance hole 21. The display screen 43 is used to display images captured by the industrial camera 42 and the industrial camera 573 in real time. The installation structure of the display screen 43 displaying images captured by the industrial camera 42 and the industrial camera 573 in real time is existing technology and will not be described in detail here. The symmetrical supplementary light plate 41 of the scratch detection component 4 provides a blue light source, enhancing the contrast between the scratches on the glass substrate surface and the substrate itself, facilitating the capture of scratch images by the industrial camera 42. The industrial camera 42 transmits the detection images to the display screen 43 for real-time display, allowing operators to intuitively observe the detection results, replacing manual visual inspection and improving detection efficiency and accuracy.

[0053] Combination Figures 1-10 As shown, the translation mechanism 5 includes a guide rail 51 fixedly installed on the top of the detection platform 2 and located on the other side of the clearance hole 21. A sliding seat 52 is slidably installed on the guide rail 51 in a horizontal direction. An electric slider 2 connected to the sliding seat 52 is fixedly installed on the guide rail 51. A horizontal telescopic rod 3 53 is fixedly installed on the sliding seat 52. An installation block 54 is fixedly installed at one end of the two telescopic rods 3 53 near the clearance hole 21. A drive rod 3 55 fixedly installed on the sliding seat 52 and connected to the installation block 54. Vertical telescopic rods 4 5 are symmetrically fixedly installed on the installation block 54. 6. Mounting brackets 57 are fixedly installed at the bottom of the two telescopic rods 56. A drive rod 58 connected to the mounting brackets 57 is fixedly installed on the mounting block 54. The translation mechanism 5 realizes the horizontal displacement of the sliding seat 52 through the guide rail 51 and the electric slider 2. The telescopic rod 53, in conjunction with the drive rod 55, adjusts the horizontal position of the mounting block 54. The telescopic rod 56, in conjunction with the drive rod 58, controls the vertical lifting and lowering of the mounting bracket 57, realizing the precise displacement of the marking component 6 in three-dimensional space. The multi-dimensional adjustment structure enables the marking component 6 to quickly and accurately align with the scratch position, improving the accuracy and efficiency of defect marking.

[0054] Combination Figures 1-10As shown, the marking component 6 includes a connecting block 61 installed at the bottom of the mounting bracket 57. A marking box 62 is installed at the bottom of the connecting block 61. An ink tank 63 is opened at the bottom of the marking box 62. A sponge block 64 extending to the bottom of the marking box 62 is fixed on the marking box 62 and located in the ink tank 63. In use, due to the design of the ink tank 63 in the marking box 62 of the marking component 6, the sponge block 64 absorbs ink and contacts the substrate surface. The printing and marking are gentle and do not damage the substrate. The marking is clear and not easy to fall off. The structure is simple and reliable. The marking operation is fast and convenient. Defect location can be completed immediately after inspection, which is convenient for subsequent sorting and processing.

[0055] Combination Figures 1-10 As shown, the sealing mechanism 7 includes a winding shaft 72, a sealing cloth 73, a coil spring 71, and a sliding plate 74. The winding shaft 72 is symmetrically and rotatably mounted on the bottom of the detection platform 2, located on both sides of the clearance hole 21. A coil spring 71, fixedly connected to the winding shaft 72, is fixedly mounted on the detection platform 2. A sealing cloth 73 is wound around the outside of the winding shaft 72, and the width of the sealing cloth 73 is greater than the width of the clearance hole 21. A sliding plate 74 is symmetrically and slidably mounted on the bottom of the detection platform 2, located opposite to the two winding shafts 72. The ends of the sealing cloth 73 are fixedly connected to two sliding plates 74 respectively. An electric slider three fixedly connected to the sliding plate 74 is fixedly installed on the detection platform 2. When in use, the sealing mechanism 7 drives the sliding plate 74 to slide through the electric slider three, which drives the sealing cloth 73 to unfold or rewind, so as to realize the quick sealing and opening of the clearance hole 21. The width of the sealing cloth 73 is larger than that of the clearance hole 21, so the sealing is tight and effectively blocks light leakage. The coil spring 71 assists the winding shaft 72 in winding the sealing cloth 73, and the opening and closing action is smooth and does not affect the glass substrate transfer rhythm.

[0056] Combination Figures 1-10 As shown, the mounting bracket 57 has a mounting hole 571 at its bottom and on one side of the connecting block 61. A magnifying glass 572 is fixedly installed in the mounting hole 571. An industrial camera 573 is fixedly installed on the inner side of the mounting bracket 57 and above the magnifying glass 572. In use, the magnifying glass 572 on the mounting bracket 57 can magnify the scratches. The industrial camera 573 captures the magnified scratch image and transmits it to the display screen 43, allowing the staff to clearly observe the depth, length and other details of the scratches and accurately determine the defect level. No additional inspection tools are required. Detailed observation can be completed while marking defects, simplifying the operation process and improving the efficiency and accuracy of defect classification.

[0057] Combination Figures 1-10As shown, the connecting block 61 is rotatably mounted on the bottom of the mounting frame 57. A motor 574 for driving the connecting block 61 to rotate is fixedly mounted on the mounting frame 57. A laser rangefinder sensor 611 is fixedly mounted on the side of the connecting block 61 away from the marking box 62. The connecting block 61 is driven to rotate by the motor 574, which can switch the working position of the marking box 62 and the laser rangefinder sensor 611. When detecting scratches, the marking box 62 is facing down; when detecting flatness, it is rotated so that the laser rangefinder sensor 611 faces down. The laser rangefinder sensor 611 monitors the distance between itself and the glass substrate in real time during the displacement of the mounting frame 57 to achieve flatness detection. This allows the device to perform both scratch detection and flatness detection functions, making it a multi-purpose device. The flexible rotation switching design does not affect the independent operation of each function.

[0058] Combination Figures 1-10 As shown, the bracket 322 includes a base plate 3221 fixedly installed on top of multiple telescopic rods 321. A rectangular array of vertically oriented spring telescopic rods 3222 are fixedly installed on the top of the base plate 3221. A support plate 3223 is fixedly installed on top of the multiple spring telescopic rods 3222. A pressure sensor 3224, in contact with the bottom of the support plate 3223, is fixedly installed on the top of the base plate 3221. In use, the spring telescopic rods 3222 of the bracket 322 have good buffering performance, absorbing the impact force when the glass substrate is placed, thus preventing damage to the glass substrate. The multiple spring telescopic rods 3222 are evenly distributed, ensuring balanced force on the glass substrate and stable support. The pressure sensor 3224 is in close contact with the bottom of the support plate 3223, accurately sensing changes in the force on the support plate 3223, improving the sensitivity and accuracy of weight detection, and providing reliable data support for glass substrate quality screening.

[0059] Working principle and usage process of this invention:

[0060] When inspecting glass substrates:

[0061] The sliding block 31 is slid on the slide rail 3 by the electric slider, so that one set of transfer components 32 is moved to the lower part of the clearance hole 21 and the other set of transfer components 32 is moved to the outside of the detection platform 2. The glass substrate to be tested is placed on the support plate 3223, so that the outer peripheral edge of the glass substrate is outside the support plate 3223. Under the action of the gravity of the glass substrate, a downward pressure force is applied to the support plate 3223, so that the support plate 3223 is moved downward along multiple spring telescopic rods 3222, thereby applying a downward pressure force to the pressure sensor 3224. The force detection signal of the pressure sensor 3224 changes, thereby realizing the weight detection effect of the glass substrate.

[0062] After the glass substrate is guided onto the tray 3223, the sliding block 31 is slid along the slide rail 3 by the electric slider, causing the tray 3223 located outside the detection platform 2 to move below the clearance hole 21. The bottom plate 3221 is moved upward along the telescopic rod 321 by the drive rod 323, so that the glass substrate passes through the clearance hole 21 and extends above the detection platform 2. The two drive rods 224 are controlled to move the two support blocks 223 closer to each other along the telescopic rod 222, so that both support blocks 223 are moved to the glass substrate. Below the glass substrate, the bottom plate 3221 is moved downward along the telescopic rod 321 by the second drive rod 323, and the glass substrate falls onto the two support blocks 223. The two support blocks 223 support the glass substrate. After the support plate 3223 moves to below the clearance hole 21, the sliding block 31 is moved on the slide rail 3 by the first electric slider, so that the support plate 3223 located outside the detection platform 2 moves to below the clearance hole 21. At this time, the glass substrate can be loaded onto the support plate 3223 located outside the detection platform 2.

[0063] Two sliding plates 74 are controlled to slide closer to each other at the bottom of the detection platform 2, so that the two sliding plates 74 are in contact, pulling the ends of the two sealing cloths 73 to move. The winding shaft 72 rotates at the bottom of the detection platform 2 to unfold the sealing cloths 73, and the coil spring 71 deforms. The two sealing cloths 73 seal the bottom of the clearance hole 21. The two supplementary light plates 41 are controlled to turn on, and the two supplementary light plates 41 emit blue light to illuminate the glass substrate. The industrial camera 42 captures the light source on the glass substrate and transmits it to the display screen 43 for real-time display. By observing the image on the display screen 43, the scratches on the surface of the glass substrate can be known.

[0064] When there are no scratches on the surface of the glass substrate, the two sliding plates 74 are controlled to slide away from each other at the bottom of the detection platform 2, the coil spring 71 returns to its natural state, the winding shaft 72 rotates at the bottom of the detection platform 2, the sealing cloth 73 is wound up, the sealing of the bottom of the clearance hole 21 is released, the drive rod 223 located below the clearance hole 21 is controlled to move the base plate 3221 upward along the telescopic rod 221, so that the support plate 3223 contacts the bottom of the glass substrate and lifts the glass substrate upward. The two drive rods 124 are controlled to move the two support blocks 223 away from each other along the telescopic rod 1222 to the outside of the glass substrate, and then the drive rod 223 is controlled to move the base plate away from each other. 3221 moves downward along the telescopic rod 321, causing the glass substrate to move below the clearance hole 21. The electric slider 1 causes the sliding block 31 to slide on the slide rail 3, causing the tray 3223 located outside the detection platform 2 to move below the clearance hole 21. This allows the glass substrate that has been inspected to be moved to the outside of the detection platform 2 for unloading. Similarly, the glass substrate to be inspected, which is placed on the tray 3223, is moved below the clearance hole 21. The same process is used to load and inspect the glass substrate. Through the cooperation of the two sets of transfer components 32, the loading and unloading operations of the glass substrate are performed respectively, improving the loading and unloading efficiency of the glass substrate.

[0065] When scratches are present on the glass substrate surface, the mounting bracket 57 is horizontally displaced above the glass substrate by the cooperation of the electric slider 2, drive rod 3 55, and drive rod 4 58. This moves the marking box 62 to above the scratch on the top of the glass substrate. Then, the drive rod 4 58 moves the mounting bracket 57 downward, allowing the sponge block 64 to contact the scratch on the top of the glass substrate, thus printing ink onto the glass substrate and achieving the marking effect of the scratch. During this process, when the mounting bracket 57 moves horizontally above the glass substrate, the magnifying glass 572 moves to above the scratch, thus marking the scratch. The industrial camera 573 magnifies the scratches and captures the magnified images, transmitting the images to the display screen 43 for easier observation by staff, thus helping to determine the defect level of the glass substrate. Furthermore, through the design of the laser rangefinder 611, when the mounting bracket 57 moves horizontally above the glass substrate, the motor 574 rotates the connecting block 61, causing the laser rangefinder 611 to move below the connecting block 61. During the movement of the mounting bracket 57, the distance between the glass substrate and the laser rangefinder 611 is monitored in real time, achieving the effect of detecting the surface flatness of the glass substrate.
