[0006] The technical problem solved by this invention is to address the issue that, in the prior art, when the curved optical glass is fixed by clamping from above and below, it is prone to tilting, which affects the detection results.

[0007] The present invention can be achieved by the following technical solution: an optical glass surface inspection device, comprising an optical inspection device for inspecting curved glass, wherein a first clamping component and a second clamping component for clamping the curved glass are provided on the side of the optical inspection device, and the first clamping component and the second clamping component are respectively located on both sides of the curved glass.

[0008] A further technical improvement of the present invention is that: the first clamping assembly includes a rotation mechanism for realizing the rotation function, the output end of the rotation mechanism is provided with an irregular support rod and a symmetrical rod, the irregular support rod and the fixed rod are fixedly connected, and a first support mechanism and a second support mechanism are respectively provided on the irregular support rod and the symmetrical rod, and an intermediate support mechanism is provided at the fixed part of the irregular support rod and the symmetrical rod.

[0009] A further technical improvement of the present invention is that: the rotating mechanism includes a top motor, which is fixed on a fixed frame; the connection between the irregular support rod and the symmetrical rod is fixed with a top rotating part; and the top rotating shaft is installed at the output end of the top motor.

[0010] A further technical improvement of the present invention is that the irregular support rod and the symmetrical rod are arc-shaped.

[0011] A further technical improvement of the present invention is that: the first support mechanism includes a clamping base, a clamping power component is fixed on the clamping base, and a clamping slide plate for clamping curved glass is provided at the output end of the clamping power component.

[0012] A further technical improvement of the present invention is that the clamping power assembly includes a moving limiting module, a power module and a clamping module. The moving limiting module is fixedly installed on the clamping base, and the power module is installed on the clamping base. The output end of the power module is provided with the clamping module.

[0013] A further technical improvement of the present invention is that: the movable limiting module includes two sets of symmetrically arranged sliding limiting seats, the sliding limiting seats are provided with sliding limiting grooves, the sliding limiting grooves are slidably arranged with limiting sliders inside, and a connecting slide plate is fixed between adjacent limiting sliders.

[0014] A further technical improvement of the present invention is that: the power module includes a sliding motor, the sliding motor is fixedly mounted on the clamping base, the output end of the sliding motor is symmetrically provided with symmetrical screws, the clamping base is fixedly mounted with a power base, the power base and the symmetrical screws are rotatably connected, and the symmetrical screws are symmetrically threaded with connecting slide plates.

[0015] A further technical improvement of the present invention is that: the clamping module includes a clamping support plate, a connecting slider is fixedly mounted on the clamping support plate, a clamping sliding base is fixed on the clamping support plate, a clamping groove is provided on the clamping sliding base, a clamping spring is fixed inside the clamping groove, a clamping slider is fixed at the end of the clamping spring, and a clamping slide plate is provided at the output end of the clamping slider.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. This application improves the detection accuracy and stability of curved glass: by setting a first clamping component and a second clamping component on both sides of the curved glass, and using a first support mechanism, an intermediate support mechanism and a second support mechanism to clamp both sides of the glass, the traditional top and bottom clamping method is replaced, which effectively avoids the curved glass from tilting or deviating during the detection process, thereby ensuring the detection accuracy of the optical detection device.

[0018] 2. This application enhances the versatility and adaptability of the device: the first clamping assembly is equipped with a rotating mechanism (such as a top motor) that can drive the irregular support rods and symmetrical rods to rotate, thereby adjusting the relative positions of each support mechanism. Simultaneously, each support mechanism can also achieve its own angle adjustment through an independent drive motor and mounting shaft. This allows the device to flexibly adapt to curved glass of different curvatures and sizes without the need to replace special clamps.

[0019] 3. This application achieves a stable and flexible clamping function: the support mechanism employs a movable limiting module (sliding limiting seat and limiting slider) and a power module (symmetrical screw and sliding motor) to ensure the smooth lateral movement of the clamping slide. Simultaneously, the clamping module includes clamping springs and clamping sliders, which can apply elastic clamping force to the curved glass, ensuring both secure fixing and avoiding potential glass damage caused by rigid clamping.

[0020] 4. This application supports multi-angle and all-round inspection needs: Through the independent rotation capabilities of the rotating mechanism and each support mechanism, the device can adjust the orientation or posture of the curved glass in the clamping state. With the help of optical inspection devices (point light source and camera) to illuminate and photograph from different angles, it is beneficial to fully capture the reflected light on the glass surface and more accurately determine whether there are surface defects such as scratches.

[0024] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0025] Please see Figure 1-6 As shown, an optical glass surface inspection device includes an optical inspection device 3 for inspecting curved glass 1, and a first clamping component 2 and a second clamping component 4 for clamping the curved glass 1. The first clamping component 2 and the second clamping component 4 are respectively clamped to the side of the curved glass 1. Therefore, in use, the first clamping component 2 and the second clamping component 4 are used to clamp and fix the curved glass 1, and then the optical inspection device 3 is used to perform optical inspection on the curved glass 1. In this application, the optical inspection device 3 includes a point light source for illuminating the curved glass 1, and a camera is also provided on the optical inspection device 3. The point light source is used to illuminate the curved glass 1, and then the camera is used to capture the emitted light from the curved glass 1 to determine whether there are defects on the curved glass 1.

[0026] As a further embodiment of this application, in order to achieve clamping of the curved glass 1, the first clamping component 2 and the second clamping component 4 have the same structure. Taking the first clamping component 2 as an example, the first clamping component 2 includes a rotating mechanism, wherein the output end of the rotating mechanism is provided with an irregular support rod 6 and a symmetrical rod 8, wherein the irregular support rod 6 and the symmetrical rod 8 are fixedly connected, and the rotation of the irregular support rod 6 and the symmetrical rod 8 is controlled by the rotating mechanism. An intermediate support mechanism 11 is fixedly installed at the connection part of the irregular support rod 6 and the symmetrical rod 8, wherein the side of the irregular support rod 6 is fixed with a first support mechanism 5, and the side of the symmetrical rod 8 is fixed with a first support mechanism 5. A second support mechanism 9 is fixed to the side. In use, the rotation mechanism controls the rotation of the irregular support rod 6 and the rotating rod 8, thereby adjusting the position of the first support mechanism 5 and the second support mechanism 9 relative to the intermediate support mechanism 11. Therefore, in use, the rotation mechanism can be used to clamp curved glass 1 with different curvatures. The first support mechanism 5, the intermediate support mechanism 11 and the second support mechanism 9 are used to clamp the curved glass 1 on both sides, rather than the common top and bottom clamping method, so as to fix the curved glass 1, avoid the deviation problem of the curved glass 1 during the inspection, and ensure the inspection accuracy of the curved glass 1.

[0027] Furthermore, the rotating mechanism includes a top motor 25, which is fixed on a fixed frame. The irregular support rod 6 and the symmetrical rod 8 are fixedly connected. A top rotating shaft is fixedly installed at the connection between the irregular support rod 6 and the symmetrical rod 8. The top rotating shaft is installed at the output end of the top motor. By starting the top motor 25, the rotation of the top rotating shaft is controlled, thereby controlling the rotation of the irregular support rod 6 and the symmetrical rod 8. This allows for the adjustment of the positions of the first support mechanism 5, the second support mechanism 9, and the intermediate support mechanism 11, enabling them to adapt to curved glass 1 with different curvatures and clamp the curved glass 1.

[0028] Furthermore, both the irregular support rod 6 and the symmetrical rod 8 are arc-shaped. When the rotating mechanism rotates, it can adaptively adjust the first support mechanism 5 and the second support mechanism 9, which are respectively located on the intermediate support mechanism 11, so as to clamp the arc-shaped glass 1 with different curvatures.

[0029] Furthermore, since the first support mechanism 5, the intermediate support mechanism 11, and the second support mechanism 9 have the same structure, the first support mechanism 5 will be disclosed as an example. The first support mechanism 5 includes a clamping base 12, on which a clamping power component is fixed. A clamping slide plate 22 for clamping the curved glass 1 is provided at the output end of the clamping power component. In use, the clamping slide plate 22 contacts the curved glass 1, and then the clamping power component is used to clamp it onto the curved glass 1 to fix the curved glass 1.

[0030] Furthermore, the clamping power assembly includes a moving limit module, a power module, and a clamping module. The moving limit module and the power module are provided on the clamping base 12. The clamping module is placed at the output end of the power module. The power module is used to start and control the clamping module to move laterally. At the same time, the moving limit module is used to control the stability of the movement of the clamping module. Then, the clamping module is used to clamp the curved glass 1.

[0031] Specifically, the movable limiting module includes two sets of symmetrically arranged sliding limiting seats 14, wherein a sliding limiting groove 20 is provided on the sliding limiting seat 14, and a limiting slider 15 is slidably arranged inside the sliding limiting groove 20. A connecting slide plate 16 is fixed between adjacent limiting sliders 15. In use, the limiting slider 15 and the sliding limiting groove 20 are slidably connected. Therefore, when the power module acts on the connecting slide plate 16, it controls the limiting slider 15 to slide inside the sliding limiting groove 20, thereby maintaining the stability of the connecting slide plate 16.

[0032] The power module includes a sliding motor 19, which is fixedly mounted on the clamping base 12. A symmetrical screw 13 is provided at the output end of the sliding motor 19. A power base 17 is fixed on the clamping base 12, and the power base 17 and the symmetrical screw 13 are rotatably connected. The symmetrical screw 13 is symmetrically threaded onto the connecting slide plate 16. The clamping module is installed at the output end of the connecting plate 16. In use, the starting of the sliding motor 19 controls the rotation of the symmetrical screw 13, thereby driving the connecting slide plate 16 to move. This allows control of the distance between adjacent clamping modules, realizing the clamping function or the retraction function.

[0033] Specifically, the clamping module includes a clamping support plate 18, which is fixedly mounted on the connecting slide plate 16. A clamping sliding base 24 is fixed on the clamping support plate 18, and a clamping groove is provided on the clamping sliding base 24. A clamping spring 23 is fixed inside the clamping groove, and a clamping slider 21 is fixed at the end of the clamping spring 23. A clamping slide plate 22 is provided at the output end of the clamping slider 21. In use, the clamping slide plate 22 is used to clamp the curved glass 1, while the clamping slider 21 compresses the clamping spring 23, thereby achieving stable clamping of the curved glass 1.

[0034] Furthermore, to adapt to the shape of the curved glass 1, the first clamping mechanism 5 is installed at the output end of the mounting shaft 10, i.e., inside the irregular support rod 6, a miniature chassis 26 is provided. The miniature chassis 26 has a power slot 27 inside, and a connecting shaft 29 is rotatably mounted inside the power slot 27. A mating gear 28 is fixed on the connecting shaft 29, and the mating gear 28 is fixedly connected to the mounting shaft 10. A drive motor 30 is fixed to the side of the power slot 27. The output end of the machine 30 is provided with a damping shaft 31, and a drive gear 32 is fixed on the damping shaft 31. The drive gear 32 and the mating gear 28 are meshed and connected. Therefore, in use, the drive motor 30 drives the damping shaft 31 to rotate, thereby driving the drive gear 32 to rotate. Under the meshing action of the mating gear 29 and the drive gear 32, the connecting shaft 29 is driven to rotate, which in turn drives the mounting shaft 10 to rotate, controlling the rotation of the first clamping mechanism 5, so as to clamp the curved glass 1 with different curvatures.

[0035] In use, the present invention uses the first clamping component 2 and the second clamping component 4 to clamp and fix the curved glass 1, and then uses the optical inspection device 3 to perform optical inspection on the curved glass 1. In this application, the optical inspection device 3 includes a point light source for illuminating the curved glass 1, and is also equipped with a camera. The point light source is used to illuminate the curved glass 1, and then the camera is used to capture the emitted light from the curved glass 1 to determine whether there are defects on the curved glass 1.

[0036] In the above process, the rotating mechanism is used to clamp curved glass 1 with different curvatures. The first support mechanism 5, the intermediate support mechanism 11 and the second support mechanism 9 are used to clamp the curved glass 1 on both sides, rather than the common top and bottom clamping method. This can fix the curved glass 1, avoid the deviation problem of the curved glass 1 during the test, and ensure the test accuracy of the curved glass 1.

[0037] When the first support mechanism 5 is in use, the drive motor 30 first drives the damping shaft 31 to rotate, thereby driving the drive gear 32 to rotate. Under the meshing action of the cooperating gear 29 and the drive gear 32, the connecting shaft 29 is driven to rotate, which in turn drives the mounting shaft 10 to rotate, thus controlling the rotation of the first clamping mechanism 5 and realizing the clamping of curved glass 1 with different curvatures. The power module is then used to control the clamping module to move laterally, while the movement limit module is used to control the stability of the clamping module's movement. The clamping module is then used to clamp the curved glass 1.

[0038] The starting of the sliding motor 19 controls the rotation of the symmetrical screw 13, thereby driving the movement of the connecting slide plate 16. This allows control of the distance between adjacent clamping modules, enabling clamping or retraction. At this time, the limiting slider 15 slides inside the sliding limiting groove 20 to maintain the stability of the connecting slide plate 16. The clamping slide plate 22 clamps the curved glass 1, while the clamping slider 21 compresses the clamping spring 23, thus achieving stable clamping of the curved glass 1.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
