Description

Technical Field

[0001] This invention relates to the field of screen defect recognition and detection, specifically to a screen defect recognition and detection device based on optical detection. Background Technology

[0002] During the manufacturing process, screens used for display may develop defects on their surface that are difficult to detect with the naked eye, such as dark spots that interfere with normal screen use or scratches that affect the product's appearance. These problems will seriously affect the quality of the product and significantly reduce its performance.

[0003] Currently, when detecting screen defects, a common method is to illuminate the screen surface with a light source and simultaneously capture images with a high-resolution industrial camera. The difference in light reflection is used to create an image, which is then compared with an image of a flawless screen using a computer to detect defects. However, if there are impurities such as dust or debris on the screen surface, the camera may misjudge them as dark spots or other defects, thus affecting the accuracy of the detection.

[0057] In the above, the pushing spring 416 and the extrusion block 413 are arranged to cooperate with each other, so that the pushing spring 416 always pushes the extrusion block 413 to move downward, and the extrusion block 413 pushes the cleaning cloth 401 to be in a tight state, reducing the problem that the friction is not enough due to the relaxation of the cleaning cloth 401 and cannot move; the moving door 13 is arranged, so that when it is closed, the mounting shell 11 generates a closed space to reduce the problem that external light irradiates into the inner side of the mounting shell 11 to interfere with the detection accuracy, and when it is opened, the staff can take out the collecting box 15 to clean the dust inside.

[0058] The ventilation mechanism 5 comprises a fan blade 501, a third bevel gear 502, a fourth bevel gear 503 and a ventilation plate 504; the third bevel gear 502 is fixedly connected to the bottom surface of the drive sleeve 403 away from the first bevel gear 405; the fourth bevel gear 503 is meshingly connected to one side of the third bevel gear 502 close to the circular groove of the mounting shell 11; the ventilation plate 504 is fixedly connected to the inner side of the circular groove; the fan blade 501 is rotatably connected to the center of the side of the ventilation plate 504 away from the fourth bevel gear 503; the fan blade 501 passes through the ventilation plate 504 through a rotating shaft and is fixedly connected to the center of the fourth bevel gear 503.

[0059] In the above, the fan blade 501 is matched with the fourth bevel gear 503 through the rotating shaft, so that when the drive sleeve 403 drives the third bevel gear 502 to rotate, the fan blade 501 is driven to rotate by the fourth bevel gear 503, the fan blade 501 blows air to the outside of the mounting shell 11, and the air carrying dust in the mounting shell 11 is discharged to the inside of the mounting shell 11.

[0060] Working principle: when in use, first slide the two movable doors 13 to close, so that the inside of the mounting shell 11 is in a dark environment, reducing the influence of external light on the detection accuracy of the industrial camera 10, then rotate the rotating rudder 30104, so that the rotating rudder 30104 drives the bidirectional screw rod 30103 to rotate, and when the bidirectional screw rod 30103 rotates, the movable plate 30101 is driven to move close to each other by the fixed block 30102, the movable plate 30101 in the moving state drives the contact belt 30201 to also move close to each other by the cooperation of the connecting rod 30111 and the mounting wheel 30202, and adjusts the distance between the contact belts 30201 according to the width of the screen to be detected, so that the contact belts 30201 clamp and position the screen, reducing the problem that the screen is inclined when the industrial camera 10 detects the screen, causing one side to be undetected, when the connecting rod 30111 moves, the mounting strip 30203 also moves, and under the cooperation of the connecting plate 412, the adjusting rod 409 and the limiting roller 410 move close to or away from each other, and under the movement of the limiting roller 410, the bottom cleaning surface width of the cleaning cloth 401 is adjusted, so that the cleaning cloth 401 can adapt to screens of different widths within a certain range;

[0061] When the adjustment is completed, the irradiation lamp 9 and the motor are started, the started motor drives the driving rod 7 to rotate in the reverse direction through the two intermeshing driving gears 6, and the driving rod 7 rotates in the reverse direction, and the fixed driving wheel 30107 also rotates in the reverse direction when the driving rod 7 rotates, and the driving wheel 30107 in the rotating state drives the rotating wheel 30106 to rotate through the driving belt 30112, and since the lower surface of the rotating wheel 30106 is fixed to the upper end of the connecting rod 30111, the connecting rod 30111 is also rotated, and the connecting rod 30111 rotates to drive the contact belt 30201 to move in the direction of the irradiation lamp 9 through friction, and since the lower surface of the contact belt 30201 is in contact with the conveying belt 202, the conveying belt 202 is also driven to move through friction, and then the screen to be detected is placed on the upper surface of the conveying belt 202, and the two sides of the screen are in contact with the contact belt 30201, and at this time the contact belt 30201 in the moving state drives the screen to be detected to move in the direction of the irradiation lamp 9;

[0062] When the driving rod 7 rotates, the lower end rotating sleeve 402 also rotates in the reverse direction, and at this time the rotating sleeve 402 drives the left and right driving sleeves 403 to rotate in the reverse direction under the cooperation of the transmission belt 404, and the right driving sleeve 403 drives the first bevel gear 405 to rotate when rotating, and since the first bevel gear 405 cooperates with the second bevel gear 406, the second bevel gear 406 is also driven to rotate, and the second bevel gear 406 in the rotating state drives the driving roller 407 connected thereto to rotate, and since the driving roller 407 is located inside the driving cleaning cloth 401, the driving cleaning cloth 401 is driven to move through the friction with the cleaning cloth 401, and when the screen to be detected is located below the driving cleaning cloth 401, the driving cleaning cloth 401 is in contact with the upper surface of the screen and cleans the dust and impurities on the surface of the screen under the movement of the driving cleaning cloth 401;

[0063] After the driving cleaning cloth 401 cleans the impurities on the surface of the screen conveyed, the dust, debris and other impurities are adhered to the surface of the driving cleaning cloth 401, and when the side of the driving cleaning cloth 401 adhering the impurities is in contact with the extrusion block 413, the extrusion block 413 scrapes the dust and other impurities to the inside of the collection box 15, and the collection box 15 collects the impurities, so that the staff can clean the collection box 15 after opening the moving door 13;

[0064] The left drive sleeve 403 rotates to drive the third bevel gear 502 below to rotate, and when the third bevel gear 502 rotates, the fourth bevel gear 503 also rotates, and since the fourth bevel gear 503 is fixed with the fan blade 501 through the rotating shaft, the fan blade 501 also rotates, so that the fan blade 501 can discharge the air containing dust in the installation shell 11 to the inside of the installation shell 11, thereby reducing the problem that dust adheres to the screen surface to affect the detection result of the industrial camera 10.

[0065] The cleaned screen continues to move and is irradiated by the irradiation lamp 9 when passing below the industrial camera 10, and the screen is illuminated under the irradiation of the irradiation lamp 9, and finally the screen is photographed by the lens of the industrial camera 10, and the reflected light is collected on the internal sensor, the light is converted into an electrical signal by the sensor, and the electrical signal is converted into a digital signal by the cooperation of the processor, and the digital signal image is uploaded to the computer through the connection with the computer, so that the computer compares the photographed image with the perfect screen image, thereby detecting the defects of the screen. The detected screen is continuously driven by the contact belt 30201 and is conveyed out of the inside of the installation shell 11 for next processing.

[0066] Embodiment two:

[0067] The difference between this embodiment and embodiment one is that the inner surface of the installation shell 11 is black, and the inside of the installation shell 11 is also black, so that the light emitted by the irradiation lamp 9 is not reflected to the screen to be detected through the installation shell 11, thereby reducing the problem that the accuracy of the industrial camera 10 is disturbed.

[0068] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
