Description

Technical Field

[0001] The present invention belongs to the technical field related to inspection machines, and particularly relates to an edge inspection machine for TFT-LCD and OLED substrate glass. Background Art

[0002] TFT is the abbreviation of thin film transistor. TFT displays are the mainstream display devices on various notebook computers and desktop computers. Each liquid crystal pixel point on such displays is driven by a thin film transistor integrated behind the pixel point. Therefore, TFT displays are also a type of active matrix liquid crystal display device and are one of the best LCD color displays. TFT displays have advantages such as high response, high brightness, and high contrast, and their display effects are close to those of CRT displays. At the same time, TFT screens are also widely used in mid- to high-end color screen mobile phones, which are divided into three types: 65,536 colors, 160,000 colors, and 16 million colors, and their display effects are very excellent. TFT means that each liquid crystal pixel point on the liquid crystal display is driven by a thin film transistor integrated behind it, so that high-speed, high-brightness, and high-contrast display of screen information can be achieved. TFT-LCD (thin film transistor liquid crystal display) is one of the most common liquid crystal displays.

[0003] The existing technologies of TFT-LCD and OLED substrate glass edge inspection machines have the following problems: When the existing TFT-LCD and OLED substrate glass edge inspection machines are in use, the substrate glass needs to be placed on the inspection table inside the inspection box, then the box door is closed and the inspection machine is started. The inspectors inside the inspection box will illuminate the substrate glass on the inspection table and complete the inspection operation. However, the substrate glasses to be inspected are diverse, so the inspection distances between each substrate glass and the inspectors will be different. However, the use height of the inspection table cannot be adjusted. Therefore, some substrate glasses, after being placed on the inspection table, are not at the optimal inspection distance, which will affect the inspection accuracy of the substrate glass. Summary of the Invention

[0004] The purpose of the present invention is to provide an edge inspection machine for TFT-LCD and OLED substrate glass to solve the problem proposed in the above background art that the inspection distances between each substrate glass and the inspectors are different, but the use height of the inspection table cannot be adjusted. Therefore, some substrate glasses, after being placed on the inspection table, are not at the optimal inspection distance, which will affect the inspection accuracy of the substrate glass.

[0005] To achieve the above object, the present invention provides the following technical solutions: A TFT-LCD and OLED substrate glass edge inspection machine, comprising an equipment chassis and an inspection box. The inspection box is installed at the upper end of the equipment chassis. At the four corners of the bottom of the equipment chassis, placement feet are provided. At the front end of the inspection box, a box door is provided. Inside the center of the box door, an observation window is provided. On the outer wall of the inspection box near the upper right rear corner, an indicator light is provided. Inside the top of the inspection box, a guide rail box is provided. Vertically inside the guide rail box, an inspector is connected downwardly through. At the inner wall of the bottom end of the inspection box near the four corners, brackets are provided. The tops of the four brackets are connected to an inspection table. Vertically downward through the center of the inspection table, a lifting inspection device is provided. The lifting inspection device includes a lifting screw, a lifting screw hole, a lifting column, a fixed perforation, a movable perforation, a hidden groove, a lifting tray and an operation hole. The hidden groove is provided inside the upper half of the center of the inspection table. The fixed perforation vertically penetrates through the outer wall of the center of the bottom end of the inspection box and the inner part of the outer wall of the center of the top end of the equipment chassis. The fixed perforation vertically penetrates through a lifting column. Inside the lifting column, a lifting screw hole with an upward opening is provided. Inside the lifting screw hole, a lifting screw penetrates upwardly. At the center of the bottom of the hidden groove, a movable perforation is connected. The top end of the lifting screw penetrates through the movable perforation and is provided inside the hidden groove. The top end of the lifting screw is connected to a lifting tray. Vertically inside the lifting tray near the left and right sides, operation holes penetrate through.

[0006] Preferably, on the outer wall of the right end of the lowermost side of the inspection box, an operation frame is provided. At the upper rear side of the operation frame, a display is provided. At the front side of the bottom of the display, an operation keyboard is provided.

[0007] Preferably, between the equipment chassis and the four placement feet at the bottom, they are all fixedly connected by screws. At the lower ends of the four placement feet, anti-slip pads are provided. The outer walls of the lower ends of the four anti-slip pads are all on the same horizontal plane.

[0008] Preferably, inside the outer wall of the rear end of the outermost side of the box door, a magnetic pad is also embedded. The magnetic pad can be completely adsorbed and attached to the front outer wall of the inspection box by its own magnetic force. The left end of the box door is fixedly connected to the inspection box through a hinge. The opening and closing angle of the box door rotating through the hinge is greater than 180 degrees.

[0009] Preferably, the inspector can be adjusted and moved in the front, back, left and right directions through the guide rail box. The inspection table is horizontally placed inside the inspection box. After the inspection by the inspector is completed, the indicator light will flash and emit a reminder.

[0010] Preferably, after the lifting tray is completely embedded into the hidden groove, the upper outer wall of the lifting tray is flush with the upper outer wall of the inspection table. The cross-sectional shape of the lifting tray is circular.

[0011] Compared with the prior art, the present invention provides a TFT-LCD.OLED substrate glass edge inspection machine, which has the following beneficial effects:

[0012] 1. The present invention adds a downward through-type lifting inspection device inside the center of the inspection table of the edge inspection machine. After placing the substrate glass to be inspected on the lifting inspection device, the lifting inspection device can lift and raise the substrate glass upward, so that the substrate glass can slowly approach the inspector when rising, thereby being able to change the distance between the inspector and the inspected substrate glass. In this way, when inspecting various different substrate glasses, the inspection distance can be adjusted correspondingly according to the inspection requirements, thereby increasing the inspection accuracy and flexibility of the entire edge inspection machine;

[0013] 2. The specific usage method of the lifting inspection device of the present invention is as follows. First, the component that can lift the substrate glass and rise is the lifting tray. When the entire lifting inspection device is not in use, the lifting tray will be completely embedded in the hidden groove inside the upper half of the inspection table, so as not to affect the normal placement of the substrate glass on the inspection table for inspection. When the substrate glass needs to approach the inspector for inspection, first, the usage height of the lifting inspection device needs to be adjusted. During the adjustment, the user only needs to insert a finger into the operation holes near both sides of the lifting tray and drive the lifting tray to rotate counterclockwise. When the lifting tray rotates counterclockwise, it will drive the lifting screw rod penetrating through the lifting screw hole to synchronize. Since the lifting screw hole is inside the lifting column, when the lifting screw rod rotates counterclockwise in the lifting screw hole, it will move upward through the thread action, thereby driving the lifting tray to move upward until the distance between the lifting tray and the inspector meets the distance required for the substrate glass to be inspected, and then the operation can be stopped. Then, the substrate glass needs to be placed on the lifting tray. At this time, the distance between the substrate glass placed on the lifting tray and the inspector will be smaller than the distance between the substrate glass placed on the inspection table and the inspector, so as to achieve the purpose of changing the distance between the substrate glass and the inspector to increase the inspection accuracy.

Specific implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4, the present invention provides a technical solution: a TFT-LCD / OLED substrate glass edge inspection machine, including an equipment chassis 2 and an inspection box 5. The inspection box 5 is installed at the upper end of the equipment chassis 2. At the four corners of the bottom of the equipment chassis 2, there are placement feet 1. The equipment chassis 2 and the four placement feet 1 at the bottom are fixedly connected by screws. At the lower ends of the four placement feet 1, there are anti-slip pads. The outer walls of the lower ends of the four anti-slip pads are all on the same horizontal plane. Contacting the ground through the anti-slip pads can increase the friction with the ground, thereby increasing the placement stability of the entire TFT-LCD / OLED substrate glass edge inspection machine. At the front end of the inspection box 5, there is a box door 3. Inside the outer wall at the rear end of the outermost side of the box door 3, there is also an embedded magnetic pad. The magnetic pad can be completely adsorbed and attached to the front outer wall of the inspection box 5 through its own magnetism. The left end of the box door 3 is fixedly connected to the inspection box 5 through a hinge. The opening and closing angle of the box door 3 rotating through the hinge is greater than 180 degrees. The large-angle opening of the box door 3 can facilitate, quickly and safely place the substrate glass on the inspection table 11, preventing the box door 3 from hitting the substrate glass when the opening angle is small. Inside the center of the box door 3, there is an observation window 4. On the upper outer wall near the right rear corner of the inspection box 5, there is an indicator light 6. Inside the top of the inspection box 5, there is a guide rail box 13. Vertically inside the guide rail box 13, there is a downwardly penetrating inspector 12. Near the four corners of the inner wall at the bottom of the inspection box 5, there are brackets 10. The tops of the four brackets 10 are connected to an inspection table 11. Vertically downward through the center of the inspection table 11, there is a lifting inspection device 14. On the outer wall at the rightmost lower side of the inspection box 5, there is an operation frame 7. At the upper rear side of the operation frame 7, there is a display 9. In the front side at the bottom of the display 9, there is an operation keyboard 8. The inspector 12 can be adjusted in the front, back, left, and right directions through the guide rail box 13. The inspection table 11 is horizontally placed inside the inspection box 5. After the inspector 12 finishes the inspection, the indicator light 6 will flash to give a reminder. When the inspector 12 inspects the substrate glass, at this time, the guide rail box 13 can enable the inspector 12 to move around the edge trajectory of the substrate glass, thereby increasing the inspection accuracy of the substrate glass.

[0022] TFT-LCD and OLED Substrate Glass Edge Inspection Machine. The lifting inspection device 14 includes a lifting screw 15, a lifting screw hole 16, a lifting column 17, a fixed perforation 18, a movable perforation 19, a built-in groove 20, a lifting tray 21, and an operation hole 22. The built-in groove 20 is arranged inside the upper half of the center of the inspection table 11. The fixed perforation 18 vertically penetrates the outer wall at the center of the bottom end of the inspection box 5 and the inner wall at the center of the top end of the equipment chassis 2. The lifting column 17 is vertically penetrated by the fixed perforation 18. The lifting screw hole 16 with an upward opening is arranged inside the lifting column 17. The lifting screw 15 penetrates upward through the lifting screw hole 16. The movable perforation 19 is connected to the center of the bottom of the built-in groove 20. The top end of the lifting screw 15 penetrates the movable perforation 19 and is arranged inside the built-in groove 20. The top end of the lifting screw 15 is connected to the lifting tray 21. The operation holes 22 penetrate vertically through the inner parts near the left and right sides of the lifting tray 21. After the lifting tray 21 is completely embedded into the built-in groove 20, the upper outer wall of the lifting tray 21 is flush with the upper outer wall of the inspection table 11. The cross-sectional shape of the lifting tray 21 is circular. When the substrate glass needs to be close to the inspector 12 for inspection, first, the use height of the lifting inspection device 14 needs to be adjusted. During the adjustment, the user only needs to insert a finger into the operation holes 22 near the two sides of the lifting tray 21 and drive the lifting tray 21 to rotate counterclockwise. When the lifting tray 21 rotates counterclockwise, it will drive the lifting screw 15 penetrating through the lifting screw hole 16 to move synchronously. Since the lifting screw hole 16 is inside the lifting column 17, when the lifting screw 15 rotates counterclockwise in the lifting screw hole 16, it will move upward through the thread action, thereby driving the lifting tray 21 to move upward until the distance between the lifting tray 21 and the inspector 12 meets the distance required for the substrate glass to be inspected, and then the operation can be stopped. Then, the substrate glass needs to be placed on the lifting tray 21. At this time, the distance between the substrate glass placed on the lifting tray 21 and the inspector 12 will be smaller than the distance between the substrate glass placed on the inspection table 11 and the inspector 12.

[0023] Working principle and usage process of the present invention: After the present invention is installed, when using the TFT-LCD / OLED substrate glass edge inspection machine, first, the entire inspection machine needs to be placed in the inspection workshop through the four placement feet 1 at the bottom of the equipment chassis 2. Then, the entire TFT-LCD / OLED substrate glass edge inspection machine needs to be powered on. When using the TFT-LCD / OLED substrate glass edge inspection machine to inspect the substrate glass, first, the door 3 at the front end of the inspection box 5 needs to be opened. Then, the substrate glass to be inspected is placed on the inspection table 11 inside the inspection box 5. Then, the position of the placed substrate glass is adjusted so that it is in the best inspection position after being placed. Then, the door 3 needs to be closed again. When the door 3 is completely closed, at this time, the inspection mode of the TFT-LCD / OLED substrate glass edge inspection machine needs to be controlled through the operation keyboard 8 and started. The inspector 12 inside the inspection box 5 will move around the edge of the substrate glass driven by the guide rail box 13 and inspect the substrate glass. After the inspection is completed, the indicator light 6 will flash, thus reminding the operator that the inspection of the substrate glass is completed. Then, the door 3 needs to be opened and the inspected substrate glass is taken out, and the inspected data is read through the display 9 and recorded and saved.
