Description

Technical Field

[0001] This utility model relates to the field of ultra-thin flexible glass inspection technology, and in particular to an ultra-thin flexible glass defect inspection device. Background Technology

[0002] Flexible glass refers to glass with a thickness of 0.1 mm or less, belonging to the category of ultra-thin glass. It is usually soda-lime glass, high-alumina glass, or low-alkali glass. It is a bendable and very flexible product.

[0003] However, currently, the defect detection process on both sides of ultra-thin flexible glass requires a large number of manual inspections under strong light, which is not only inefficient and has a high rate of missed detections, but also poses serious occupational hazards. Prolonged exposure to strong light can damage the eyes of the inspectors. Although some factories have tried to use line-scan laser cameras to detect defects on both sides of flexible glass, these line-scan laser cameras do not have the ability to distinguish between real defects and false defects, resulting in high rates of missed detections or high rates of over-detection. Utility Model Content

[0004] The purpose of this invention is to provide a defect detection device for ultra-thin flexible glass to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: it includes a lower frame, on which a main body mechanism is provided, and on top of the main body mechanism an upper frame is provided;

[0006] The main structure includes a base, on one side of which is a double-acting linear motor II. A feeding platform is provided at one end of the double-acting linear motor II, and a tilting platform is provided at the end of the double-acting linear motor II away from the feeding platform. A double-acting linear motor I is provided on the side of the base away from the double-acting linear motor II, with a transfer platform at one end of the double-acting linear motor I and a discharge platform at the end of the double-acting linear motor I away from the transfer platform. A pair of detection units are symmetrically arranged in the middle of the base.

[0007] As a preferred embodiment of the present invention, the detection unit includes a profile frame mounted on a base, a manual Z-axis adjustment stage is provided on one side of the profile frame, and a phase optical module is provided on the manual Z-axis adjustment stage.

[0008] As a preferred embodiment of this utility model, a feeding suction fork is movably arranged on the feeding platform, a servo motor is arranged on one side of the feeding platform, a T-axis reducer is arranged at the transmission end of the servo motor, the transmission end of the T-axis reducer is connected to one end of the feeding suction fork, and a feeding positioning block is arranged on the feeding suction fork.

[0009] As a preferred embodiment of this utility model, the flipping platform includes a Z-axis lifting module one, on which a flipping adsorption fork is movably mounted. A servo motor two is mounted on one side of the Z-axis lifting module one, and a T-axis reducer two is mounted on the transmission end of the servo motor two. The transmission end of the T-axis reducer two is connected to one end of the flipping adsorption fork. Flexible glass is mounted on the flipping adsorption fork, and the hollowed-out areas on the feeding adsorption fork and the flipping adsorption fork are complementary.

[0010] As a preferred embodiment of this utility model, the transfer platform includes a second Z-axis lifting module, and the second Z-axis lifting module is provided with a transfer adsorption tooth fork.

[0011] As a preferred embodiment of this invention, the feeding platform includes a feeding adsorption fork, and the connecting adsorption fork is complementary to the hollowed-out area on the feeding adsorption fork.

[0012] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0013] This invention features a dual-actuator linear motor, a feeding platform, and a tilting platform. The dual-actuator design of the dual-actuator linear motor allows for independent and precise driving of both the feeding and tilting platforms, enabling flexible and efficient transport of flexible glass, reducing time and positional errors, and improving overall efficiency. Secondly, the feeding platform, combined with a servo motor and a T-axis reducer, allows the feeding suction fork to tilt and lift precisely at a 45-degree angle, facilitating manual or mechanical gripper feeding and reducing labor intensity. Simultaneously, the feeding positioning block ensures stable and accurate feeding. Furthermore, the tilting platform, through the coordinated operation of a Z-axis lifting module, a servo motor, and a T-axis reducer, not only achieves precise lifting and lowering of the tilting suction fork, efficiently transferring the flexible glass to the feeding suction fork, but also allows for a smooth 180-degree tilt to transfer the flexible glass to the handover suction fork, enabling front-to-back conversion. Finally, the complementary hollow areas of the feeding and tilting suction forks not only ensure smooth handover but also allow for full-coverage photographic inspection of the flexible glass's front side, improving the comprehensiveness and accuracy of the inspection.

[0014] This invention features a dual-actuator linear motor, a transfer platform, and a feeding platform. The dual-actuator structure of the linear motor allows the transfer platform and feeding platform to operate independently and efficiently, moving quickly and accurately to ensure a smooth testing process and improve testing accuracy. Secondly, the transfer platform precisely transfers the flexible glass to the feeding platform via a Z-axis lifting module. The complementary cutout areas of the transfer and feeding suction forks not only ensure smooth and accurate transfer of the flexible glass but also guarantee full coverage of the reverse side for photographic inspection, improving the comprehensiveness and accuracy of the inspection. Furthermore, after all front and back sides have been photographed and inspected, the feeding platform can quickly move the flexible glass to the feeding position, ensuring timely and orderly removal from the equipment, facilitating continuous production and improving overall efficiency.

[0015] This invention employs a pair of detection units: one detection unit for the front side of flexible glass and the other for the back side. A phase-optical module is used as the optical detection solution. This solution can acquire multi-dimensional images in a single shot. Phase-based optical computation can fully establish microscopic 3D features and microscopic optical characteristics for highly reflective surfaces, capturing all defect types in principle. Sensitivity in the Z-direction can reach the nanometer level, capturing previously invisible micro-defects and reducing the false negative rate. The software uses an AI detection algorithm. By processing images of real defects and extracting useful feature information, and through deep learning algorithms, the software can distinguish between real and false defects, filtering out imperfections such as dirt and fingerprints, preventing these false defects from interfering with the detection algorithm and thus reducing the false positive rate.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0023] like Figures 1-5 As shown, the present invention proposes an ultra-thin flexible glass defect detection device, which includes a lower frame 3, a main body mechanism 2 on the lower frame 3, and an upper frame 1 on the top of the main body mechanism 2.

[0024] The main body 2 includes a base 2-4, which provides the mounting foundation for other components in the main body 2. A dual-actuator linear motor 2-8 is installed on one side of the base 2-4. This motor independently drives the loading platform 2-1 and the tilting platform 2-3 in linear motion, without interference, reducing vibration and ensuring detection accuracy. The loading platform 2-1 is mounted on one end of the dual-actuator linear motor 2-8. The loading platform 2-1 can be raised 45 degrees for easy manual or robotic loading. After loading, the glass returns to a horizontal position and moves to below the front detection unit 2-2 on the left side to complete the detection of half of the front side. A flipping platform 2-3 is located on the end of the double-acting linear motor 2-8 away from the loading platform 2-1. The flipping platform 2-3 can lift the flexible glass 4 from below, completing the handover of the flexible glass 4 to the loading platform 2-1. It then moves to below the front detection unit 2-2 on the left side to complete the detection of the remaining half of the front side. After detection, it flips 180 degrees to hand over the flexible glass 4 to the handover platform. On platform 2-5 and base 2-4, a double-acting linear motor 2-7 is located on the side away from the second double-acting linear motor 2-8. The first double-acting linear motor 2-7 independently drives the transfer platform 2-5 and the unloading platform 2-6 in linear motion, without interference, reducing vibration and ensuring detection accuracy. One end of the first double-acting linear motor 2-7 is connected to the transfer platform 2-5. The transfer platform 2-5 moves to below the reverse detection unit 2-2 on the right side, completing half of the reverse side detection. Then, the transfer platform 2-5 moves to... Above the unloading platform 2-6, the flexible glass 4 is handed over to the unloading platform 2-6. The unloading platform 2-6 is located at the end of the double-acting linear motor 2-7 away from the handover platform 2-5. The unloading platform 2-6 moves to the bottom of the right-side reverse detection unit 2-2 to complete the detection of the remaining half of the reverse side of the flexible glass 4. A pair of detection units 2-2 are symmetrically arranged in the upper middle part of the base 2-4. The left detection unit 2-2 is used to detect the front defects of the flexible glass 4, and the right detection unit 2-2 is used to detect the reverse defects of the flexible glass 4.

[0025] The detection unit 2-2 includes a profile frame 2-2-3 mounted on the base 2-4. A manual Z-axis adjustment stage 2-2-2 is mounted on one side of the profile frame 2-2-3. A phase optical module 2-2-1 is mounted on the manual Z-axis adjustment stage 2-2-2. The manual Z-axis adjustment stage 2-2-2 can finely adjust the phase optical module 2-2-1 up and down to complete the camera focusing, ensure clear photography, and lock after debugging. The phase optical module 2-2-1 is used to photograph and inspect the product.

[0026] A feeding suction fork 2-1-3 is movably mounted on the feeding platform 2-1. A servo motor 2-1-1 is mounted on one side of the feeding platform 2-1. A T-axis reducer 2-1-2 is mounted on the transmission end of the servo motor 2-1-1. The transmission end of the T-axis reducer 2-1-2 is connected to one end of the feeding suction fork 2-1-3. The servo motor 2-1-1 drives the T-axis reducer 2-1-2 to generate rotational motion, thereby enabling the feeding suction fork 2-1-3 to complete the rotational action. The feeding suction fork 2-1-3 is tilted at 45 degrees to facilitate feeding, while it is kept horizontal during inspection. A feeding positioning block 2-1-4 is mounted on the feeding suction fork 2-1-3 to ensure the accuracy of the placement of the flexible glass 4 during feeding.

[0027] The flipping platform 2-3 includes a Z-axis lifting module 2-3-3, which drives a servo motor 2-3-1, a T-axis reducer 2-3-2, and a flipping suction fork 2-3-4 to move in the Z-axis direction, lifting the flexible glass 4 from below onto the loading suction fork 2-1-3, thus completing the transfer of the flexible glass 4. The flipping suction fork 2-3-4 is movably mounted on the Z-axis lifting module 2-3-3. A servo motor 2-3-1 is mounted on one side of the Z-axis lifting module 2-3-3, and a T-axis reducer 2-3-2 is mounted on the transmission end of the servo motor 2-3-1. The transmission end of 2-3-2 is connected to one end of the flipping adsorption tooth fork 2-3-4. The servo motor 2-3-1 drives the T-axis reducer 2-3-2 to generate rotational motion, thereby enabling the flipping adsorption tooth fork 2-3-4 to complete the rotation action, thereby causing the flexible glass 4 to flip 180 degrees and be handed over to the next inspection station. The flexible glass 4 is set on the flipping adsorption tooth fork 2-3-4. The hollow area on the feeding adsorption tooth fork 2-1-3 and the flipping adsorption tooth fork 2-3-4 is complementary. When the phase optical module 2-2-1 takes pictures, it is necessary to ensure that the bottom of the flexible glass 4 is in a hollow state. Therefore, two sets of complementary adsorption tooth forks are needed to complete the shooting and inspection of one side.

[0028] The transfer platform 2-5 includes a Z-axis lifting module 2-5-1, on which a transfer adsorption fork 2-5-2 is provided. The Z-axis lifting module 2-5-1 drives the transfer adsorption fork 2-5-2 to complete the movement in the Z-axis direction. When the transfer adsorption fork 2-5-2 moves to the position directly above the unloading adsorption fork 2-6-1, the Z-axis lifting module 2-5-1 drives the transfer adsorption fork 2-5-2 to descend and transfer the flexible glass 4 to the unloading adsorption fork 2-6-1.

[0029] The unloading platform 2-6 includes an unloading suction tooth fork 2-6-1, and the connecting suction tooth fork 2-5-2 complements the hollow area on the unloading suction tooth fork 2-6-1. The unloading suction tooth fork 2-6-1 can ensure the stability of the flexible glass 4 during the unloading process and move it to the unloading position for easy removal by the operator.

[0030] During use, the operator presses the equipment start button, powering on all modules and entering the initialization state. Based on the specifications of the flexible glass 4 to be tested, the operator sets the corresponding testing parameters on the operating interface. Then, the loading stage begins. The servo motor 2-1-1 drives the T-axis reducer 2-1-2 to rotate, causing the loading suction fork 2-1-3 to tilt upwards at a 45-degree angle, facilitating loading by the operator. Next, the operator places the flexible glass 4 to be tested onto the loading suction fork 2-1-3, ensuring the flexible glass 4... Aligned with the feeding positioning block 2-1-4, after placement, the feeding adsorption tooth fork 2-1-3 slowly descends to a horizontal position. Then, the front detection stage begins. Driven by the double-acting linear motor 2-8, the feeding platform 2-1 moves the flexible glass 4 into the equipment and positions it below the detection area of ​​the phase optical module 2-2-1 of the left front detection unit 2-2. The feeding platform 2-1 moves the flexible glass 4 to be photographed and detected within the field of view of the phase optical module 2-2-1, completing the preliminary detection of the front of the hollowed-out part of the flexible glass 4.

[0031] Next, the flipping suction fork 2-3-4 descends under the drive of the Z-axis lifting module 2-3-3, its height lower than the loading suction fork 2-1-3. Then, the flipping platform 2-3 moves via the dual-actuator linear motor 2-8 until the flipping suction fork 2-3-4 is directly below the loading suction fork 2-1-3. Because the cutouts of the flipping suction fork 2-3-4 and the loading suction fork 2-1-3 are complementary, the flipping suction fork 2-3-4 can slowly pass through the bottom of the loading suction fork 2-1-3 under the drive of the Z-axis lifting module 2-3-3, thus adsorbing the soft... The flexible glass 4 is lifted to a certain height, and at the same time, the vacuum of the feeding adsorption fork 2-1-3 is closed, and it returns to the feeding station to re-feed. After the flexible glass 4 is transferred to the flipping adsorption fork 2-3-4, the flipping platform 2-3, driven by the double-acting linear motor 2-8, moves the flexible glass 4 back to the detection area of ​​the left front detection unit 2-2, and takes pictures and detects it again in the field of view of the phase optical module 2-2-1. Since the hollow areas of the feeding adsorption fork 2-1-3 and the flipping adsorption fork 2-3-4 are complementary, this detection ensures that the entire area of ​​the front of the glass is covered.

[0032] Then, the flexible glass 4 is flipped and enters the reverse detection stage. Driven by the dual-actuator linear motor 2-8, the flipping adsorption fork 2-3-4 moves the flexible glass 4 to the handover station, ready to be handed over to the handover adsorption fork 2-5-2. The servo motor 2-3-1 drives the T-axis reducer 2-3-2 to rotate, causing the flipping adsorption fork 2-3-4 to flip 180 degrees. The flexible glass 4 is flipped onto the handover adsorption fork 2-5-2, which then adsorbs the flexible glass 4. The flipping adsorption fork 2-3-4 closes the vacuum and resets. Driven by the dual-actuator linear motor 2-7, the handover adsorption fork 2-5-2 moves the flexible glass 4 to below the detection area of ​​the phase optical module 2-2-1 of the right reverse detection unit 2-2. The handover adsorption fork 2-5-2 moves the flexible glass 4 to perform preliminary reverse imaging detection within the field of view of the phase optical module 2-2-1.

[0033] Next, the transfer adsorption fork 2-5-2 rises under the drive of the Z-axis lifting module 2-5-1, reaching a height higher than the unloading adsorption fork 2-6-1. Then, the transfer platform 2-5 moves via the dual-actuator linear motor 2-7 until the transfer adsorption fork 2-5-2 is directly above the unloading adsorption fork 2-6-1. Because the cutouts of the transfer adsorption fork 2-5-2 and the unloading adsorption fork 2-6-1 are complementary, the transfer adsorption fork 2-5-2 can descend under the drive of the Z-axis lifting module 2-5-1 and pass through the unloading adsorption fork 2-6-1. The unloading adsorption fork 2-6-1 then adsorbs the flexible glass 4. The transfer adsorption fork 2-5-2 closes the vacuum and resets, and the flexible glass 4 is completely transferred to... On the feeding and adsorption fork 2-6-1, driven by the dual-actuator linear motor 2-7, the feeding and adsorption fork 2-6-1 moves the flexible glass 4 back to the detection area of ​​the right-side reverse detection unit 2-2, and takes pictures again within the field of view of the phase optical module 2-2-1. Since the hollow areas of the feeding and adsorption fork 2-6-1 and the transfer adsorption fork 2-5-2 are complementary, this detection ensures that the entire area of ​​the reverse side of the glass is covered. After the front and back sides of the flexible glass 4 are completely detected, the dual-actuator linear motor 2-7 drives the feeding platform 2-6 to move the flexible glass 4 to the feeding position. The operator removes the tested flexible glass 4, and the remaining flexible glass 4 are tested in the same way.
