[0002] With the rapid development of information technology, display technology, as a core medium for human-computer interaction, is seeing its application areas continuously expand and its market size grow steadily. Glass substrates, as the core material of display modules, have become an indispensable basic component of high-end display devices due to their excellent optical transparency, mechanical strength, and chemical stability. However, the surface quality of the glass has a decisive impact on the display effect, structural strength, and long-term reliability of the final product. Currently, most mainstream glass defect detection systems place the glass on a testing rack and then inspect it through a testing mechanism. The disadvantage is that each piece of glass needs to be moved from the production line to the testing rack for inspection, creating an additional transport and transfer process and preventing online inspection. This process significantly impacts work efficiency. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides an online glass defect detection and positioning device, which solves the problem that existing glass inspection requires transporting the glass out of the production line for inspection, thus affecting production efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an online glass defect detection and positioning device, wherein the positioning device is applied between two opposing conveyor lines; the positioning device comprises: A frame for connecting to the two conveyor lines; A transmission assembly, the transmission assembly including at least a conveyor for conveying and / or guiding the glass; A calibration component, which is vertically and retractably mounted on one side of the output end of the frame; The calibration assembly includes a boom and calibration components located at both ends of the boom; During the conveying of glass, the two apex corners of the front end of the glass abut against the calibration piece to position and calibrate the glass.

[0005] Preferably, the frame includes side frame plates that can be wrapped into a rectangular structure and end frame plates disposed at the ends of the side frame plates. The bottom of the end frame plate located on the output end side of the frame is connected to the side frame plate by a bridging member, so that a gap is formed between the end frame plate on the output end side of the frame and the side frame plate above the bridging member; the calibration component is vertically and vertically disposed within the gap.

[0006] Preferably, the transmission assembly further includes: a receiving member for receiving the glass and conveying it to the calibration member; The receiving component is disposed inside the conveying component and is arranged parallel to the conveying component; The glass overlaps above the receiving and conveying components; In this embodiment, any of the conveying components drives the glass to move and / or guide on the receiving component when conveying in the forward or reverse direction.

[0007] Preferably, the conveyor is closer to the calibrator than the receiver, and the ends of the conveyor and the receiver are located above the gap.

[0008] Preferably, the conveying component includes a first conveyor belt and a second conveyor belt disposed on one side of the two side frame plates, wherein the first conveyor belt and the second conveyor belt are located on the same horizontal plane as the conveying line.

[0009] Preferably, the receiving component includes a roller array, which includes a U-shaped frame arranged along the conveying direction of the conveyor and a plurality of rollers rotatably connected within the U-shaped frame.

[0010] Preferably, the inner side of the boom is slidably connected to the end frame plate located on one side of the output end of the frame via a guide rail; a cylinder is fixed on the outer side of the end frame plate located on one side of the output end of the frame, and the output end of the cylinder is fixed on the boom to drive the boom and the calibration component to move up and down.

[0013] Preferably, the elastic telescopic member includes a rigid member fixed to the boom and a flexible member fixed to the outer wall of the calibration plate. The rigid member is hollow inside, so that the flexible member is disposed inside the rigid member. When the two apex corners of the glass abut against the calibration plate, the flexible member is compressed, so that the calibration plate abuts against the rigid member.

[0014] The beneficial effects of this utility model are as follows: By using the online glass defect detection and positioning device provided by this utility model, compared with the prior art, the positioning and correction of the glass are achieved through the coordinated work of the differential speed drive conveyor belt and the liftable calibration plate. When the glass tilts during the conveying process, one corner of it contacts the calibration plate first. At this time, the other side of the conveyor belt continues to run, driving the glass to rotate on the rollers until both ends are aligned with the calibration plate, thereby ensuring that the glass enters the detection area in a standard posture.

[0015] The calibration component is driven by a cylinder to lift and retract, and can be retracted into the gap after calibration without affecting the normal transport of subsequent glass.

[0019] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Various changes can be made to the implementation scheme as long as the effects of the present invention can be achieved.

[0021] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the art. The following mainly introduces the working principle and process.

[0022] like Figures 1 to 7As shown in the illustration, this application proposes an online glass defect detection and positioning device. The positioning device is applied between two opposing conveyor lines 1, and a glass detection mechanism, including a supplementary light and an optical camera, is positioned above the positioning device. In the prior art, the glass detection mechanism is positioned above the positioning device and performs detection on the positioning device during the glass conveying process.

[0023] Specifically, the positioning device includes a frame 2, a transmission assembly, and a calibration assembly. The frame 2 is used to connect to the two conveyor lines 1. The transmission assembly is used to position and calibrate the glass by pressing it against the calibration assembly, preventing the glass from being inspected by the inspection mechanism while tilted, thus improving the accuracy of the inspection mechanism's glass inspection.

[0024] In this embodiment, the frame 2 includes a side frame plate 21 that can be wrapped into a rectangular structure and an end frame plate 22 located at the end of the side frame plate. The bottom of the end frame plate 22 located on the output end side of the frame 2 is connected to the side frame plate 21 by a bridging member 23. The bridging member 23 is a U-shaped member, so that a gap 6 is formed between the end frame plate 22 and the side frame plate 21 on the output end side of the frame 2 above the bridging member 23. The width of the gap 6 in the top view projection needs to be greater than the sum of the widths of the boom 7, the calibration plate 10 and the elastic telescopic member 11 to ensure that the calibration component can move up and down normally.

[0025] Furthermore, the calibration component is vertically configurable on one side of the output end of the frame 2; specifically, the calibration component is vertically configurable within the gap 6. For example, when glass is conveyed from one conveyor line 1 to the other via a transmission assembly, the calibration component rises to block the glass as it falls onto the transmission assembly, positioning the glass below the detection mechanism. The orientation of the glass is calibrated through selective transmission of the transmission assembly, ensuring the glass is in the correct calibrated position for detection by the detection mechanism.

[0026] Specifically, the calibration assembly includes a boom 7 and calibration components located at both ends of the boom 7. When the glass is conveyed by the conveyor, the two apex corners of the glass front end abut against the calibration components, changing the glass from an inclined state to a centered state, thereby improving the accuracy of the testing mechanism in detecting the glass.

[0027] For example, the calibration component moves up and down via a lifting mechanism. This embodiment proposes an embodiment of the lifting mechanism, including a guide rail 8 and a cylinder 9. The inner side of the boom 7 is slidably connected to the end frame plate 22 located on one side of the output end of the frame 2 via the guide rail 8. The cylinder 9 is fixed to the outer side of the end frame plate 22 located on the output end of the frame 2, and the output end of the cylinder 9 is fixed to the boom 7, driving the boom 7 and the calibration component to move up and down. When inspecting the glass to be tested, the cylinder 9 extends, causing the boom 7 and the calibration component to rise and block the glass, positioning it before inspection. After inspection, the cylinder 9 retracts, causing the boom 7 and the calibration component to return to the gap 6, and the transmission assembly restarts to transport the glass to the next conveyor line 1.

[0028] In this embodiment, specifically as follows: Figure 5 As shown, the calibration component includes a calibration plate 10, which is rotatably connected to the boom 7 via a bearing 12. Furthermore, an elastic telescopic member 11 is provided between the calibration plate 10 and the boom 7. In the normal state, the elastic telescopic member 11 is extended, pushing the calibration plate 10 to rotate around the bearing 12, causing the calibration plate 10 to tilt, facilitating the entry of tilted glass into the inner side of the calibration plate 10. When the glass contacts the calibration plate 10, the glass's own weight and the continuous operation of the transmission assembly push the calibration plate 10 back to its original position, compressing the elastic telescopic member 11 to make the two calibration plates 10 parallel to the boom 7, thus placing the glass in the centered position after calibration. After calibration and positioning, the transmission assembly stops working, and the boom 7 and the calibration component retract into the gap 6, allowing the glass to be inspected by the testing mechanism in a static, undisturbed state.

[0029] For example, in one embodiment, the calibration plate 10 is a right-angled plate, including a first plate 101 and a second plate 102, the first plate 101 and the second plate 102 being perpendicular to each other, and forming a receiving space between the first plate 101 and the second plate 102 to accommodate the top corner of the glass.

[0030] Exemplary, in one embodiment, such as Figure 7 As shown, the elastic telescopic member 11 includes a rigid member 111 fixed to the boom 7 and a flexible member 112 fixed to the outer wall of the calibration plate 10. The rigid member 111 is preferably a metal cylinder, and the flexible member 112 is preferably a hollow sponge column. The rigid member 111 is hollow inside, and the flexible member 112 is disposed inside the rigid member 111. When the two apex corners of the glass abut against the calibration plate 10, the flexible member 112 is compressed, causing it to retract into the inner cavity of the rigid member 111, and the calibration plate 10 abuts against the end of the rigid member 111. It should be noted that when the back of the first plate 101 in the calibration plate 10 abuts against the rigid member 111, the first plate 101 is parallel to the boom 7.

[0031] In this embodiment, the transmission assembly includes at least a conveyor for conveying and / or guiding the glass. Exemplarily, the conveyor includes a first conveyor belt 4 and a second conveyor belt 5 disposed on one side of the two side frame plates 21, the first conveyor belt 4 and the second conveyor belt 5 being located on the same horizontal plane as the conveyor line.

[0032] Reference Figure 2 and Figure 3 In this embodiment, the transmission assembly further includes a receiving member for receiving and conveying the glass to the calibration member. The receiving member is disposed inside the conveyor and is arranged parallel to the conveyor. The glass overlaps the receiving member and the conveyor. Either conveyor drives the glass to move and / or guide it on the receiving member when conveying in either direction.

[0033] For example, the receiving component includes a roller array 3, which includes a U-shaped frame arranged along the conveying direction of the conveyor and a plurality of rollers rotatably connected within the U-shaped frame.

[0034] In this embodiment, the conveyor is closer to the calibrator than the receiver, and the ends of the conveyor and receiver are located above the gap 6.

[0035] During implementation, the glass is conveyed and moved on the receiving member by the first conveyor belt 4 and the second conveyor belt 5. One of the apex corners of the glass, which is in an inclined state, abuts against the calibration plate 10. At this time, the conveyor belt on the other apex corner side, which is not abutting against the calibration plate 10, operates, driving the glass to rotate on the roller row 3. Finally, after both apex corners of the glass have contacted the calibration plate 10, the first conveyor belt 4 and the second conveyor belt 5 stop working.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
