[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] See also Figure 1-3 , the utility model provides a technical solution:
[0021] See Figure 1 and Figure 2 As shown, a device for detecting the surface contour of a curved glass cover plate comprises a base plate 1, a curved glass cover plate body 14 being provided on the upper surface of the base plate 1, a detection mechanism being provided on the base plate 1, the detection mechanism comprising a lamp holder 4 mounted on one side of the upper surface of the base plate 1, a lampshade 7 being mounted on the top of the lamp holder 4, the lampshade 7 being located above the base plate 1 and parallel to the base plate 1, and LED strip lights 8 being mounted on the lower surface of the base plate 1, the number of which being four and being arranged in series.
[0022] During the specific implementation process, when the light emitted by the LED strip light 8 is vertically irradiated on the curved glass cover body 14, the light will be reflected on its surface. The distribution pattern of the reflected light can reflect the contour of the surface of the curved glass cover. The quality of its contour can be judged by observing the distribution pattern of the reflected light and shadow on the surface of the curved glass cover body 14. If the light and shadow are parallel and straight, it means that the contour of the surface of the curved glass cover body 14 is better. On the contrary, if the light and shadow are distorted, deformed or irregularly distributed, it means that its contour is poor.
[0023] See Figure 1 As shown, the lampshade 7 is symmetrically connected to connecting bars 11 on both sides, and the connecting bars 11 are rotatably connected to the damping bearing 5. The bottom of the outer arc wall of the damping bearing 5 is connected to an L-shaped plate 2. The L-shaped plate 2 is divided into a vertical end and a horizontal end. The vertical end of the L-shaped plate 2 is a telescopic rod, and the horizontal end of the L-shaped plate 2 is arranged parallel to the base plate 1. In the specific implementation process, the curved glass cover body to be inspected is placed on the base plate 1. The inclination angle of the connecting bars 11 can be easily adjusted through the damping bearing 5. When the two connecting bars 11 are tilted in opposite directions, the two ends of the curved glass cover body 14 can be parallel to the LED strip light 8. Fine adjustments are made according to the curvature and shape of the curved glass cover body 14 to ensure that the light can be evenly irradiated at its center. The vertical end of the L-shaped plate 2 is a telescopic rod. The overall height of the L-shaped plate 2 and the lampshade 7 can be adjusted by telescoping operation. Adjustment helps to adapt to curved glass cover bodies 14 of different sizes or inspection requirements.
[0024] It should be noted that rubber pads are installed on opposite sides of the vertical ends of the two connecting strips 11 to ensure that no damage is caused to the curved glass cover plate body 14 .
[0025] See Figure 1 and Figure 3As shown, a magnet block 10 is provided at the bottom of the horizontal end of the L-shaped plate 2, and a magnetic groove 13 is provided on the upper surface of the base plate 1. The magnetic groove 13 is magnetically connected to the magnet block 10, and an anti-slip pad 12 is installed on the upper surface of the base plate 1 outside the magnetic groove 13. In a specific implementation, the magnet block 10 is used to magnetically connect with the magnetic groove 13 on the base plate 1, thereby fixing the position of the L-shaped plate 2 to ensure that the L-shaped plate 2 is perpendicular to the base plate 1. The anti-slip pad 12 is used to increase the friction between the curved glass cover plate body and the base plate 1 to prevent it from sliding or shifting during the inspection process.
[0026] See Figure 1 and Figure 2 As shown, a connecting plate 9 is mounted on the side of the lampshade 7 near the lamp holder 4. A camera 6 is mounted on the side of the connecting plate 9 near the curved glass cover body 14. The power of the LED strip light 8 is 8-10W, and the height of the lamp holder 4 is 50-70cm. Universal wheels 3 are mounted on the bottom of the base plate 1. In a specific implementation, the camera 6 is used to capture images or videos of the surface of the curved glass cover body 14 and detect the contour of the curved glass cover body 14. A battery is installed on the connecting plate 9 and is electrically connected to the camera 6 to provide power to the camera 6.
[0027] Working principle:
[0028] Step 1: Place the base plate 1 steadily to ensure that the bottom surface is stable. Place the curved glass cover plate body 14 to be tested on the upper surface of the base plate 1. Adjust the inclination angle of the connecting bar 11 through the damping bearing 5 so that the light from the lampshade 7 and the LED strip light 8 can be evenly irradiated on the center position of the curved glass cover plate body 14. Use the telescopic rod function of the L-shaped plate 2 to adjust the overall height of the L-shaped plate 2 to adapt to different sizes of curved glass cover plate bodies 14 or testing requirements. Ensure that the magnet block 10 is magnetically connected to the magnetic suction groove 13 on the base plate 1 to fix the position of the L-shaped plate 2.
[0029] Step 2: Turn on the LED strip light 8, and shine light vertically on the curved glass cover body 14. The light is reflected on the surface of the curved glass cover body 14. The distribution of the reflected light reflects the contour of its surface. Observe the distribution of the reflected light and shadow on the surface of the curved glass cover body 14. If the light and shadow are parallel and straight, it means that the contour of the surface of the curved glass cover body 14 is good. If the light and shadow are distorted, deformed or irregularly distributed, it means that there is a problem with its contour.
[0030] Step 3: The camera 6 captures an image of the surface of the curved glass cover body 14. The battery on the connecting plate 9 powers the camera 6 to ensure the continuity and stability of image capture. The image or video captured by the camera 6 can be used to further analyze the contour of the curved glass cover body 14. When it is necessary to detect the curved glass cover body 14 at different positions, the device can be easily moved to the specified position.
