[0002] Automobile glass is an indispensable accessory of automobile body, and its main function is protection. When assembling the whole vehicle, the outer surface of automobile glass needs to match with the body and other parts to meet the requirements of vehicle assembly. Therefore, whether the surface curvature of the outer surface of automobile glass meets the requirements is an important indicator to judge whether the automobile glass is qualified. When producing glass, a glass curvature detection device is needed.

[0003] Current glass curvature detection devices, such as a glass outer surface curvature detection device proposed in announcement number: CN220794113U, after the positioning mechanism positions the glass, the curvature rod is installed on the tooling body. The gap between the contoured surface of the curvature rod and the outer surface of the glass is the difference between the outer surface of the glass and the design value. By measuring the specific value of the gap and comparing the value with the design tolerance, it can be determined whether the curvature of the outer surface of the glass meets the requirements.

[0004] When using the existing glass curvature detection device, it is necessary to first position the glass, then install the curvature rod, and judge whether the curvature of the glass is qualified by observing whether the curvature rod is in contact with the glass surface. This detection device is time-consuming and labor-intensive to use, as it not only needs to limit the glass, but also needs to repeatedly disassemble and assemble the curvature rod, which makes the detection efficiency of the glass curvature low and inconvenient to use.

[0026] The detection groove 4, the lower ejector rod 6 and the upper ejector rod 9 are set according to the size and standard curvature of the glass. When the curvature of the glass is detected, the glass is placed in the detection groove 4, and the lower ejector rod 6 is used to support the lower part of the glass. Then, the lifting frame 7 is controlled to move downward by the lifting mechanism so that the upper ejector rod 9 is against the top of the glass. The top of the lower ejector rod 6 and the bottom of the upper ejector rod 9 are distributed in the standard curvature of the glass. When the detected curvature of the glass is qualified, the glass is in contact with all the lower ejector rods 6 and the upper ejector rods 9. When it is unqualified, some of the lower ejector rods 6 and the upper ejector rods 9 are not in contact with the glass. The contact is monitored by the first pressure sensor 5 and the second pressure sensor 8. The signals are transmitted to the display 10 by the first pressure sensor 5 and the second pressure sensor 8. The pressure changes detected by the first pressure sensor 5 and the second pressure sensor 8 are displayed by the display 10, and the curvature of the glass can be directly detected. Through the detection device, the curvature of the glass can be quickly detected, which effectively improves the detection efficiency of the curvature of the glass.

[0029] Working principle: This glass curvature detection device for glass production sets a detection slot 4, a lower ejector rod 6 and an upper ejector rod 9 according to the size and standard curvature of the glass. When detecting the curvature of the glass, the glass is placed in the detection slot 4, and the lower ejector rod 6 is used to support the lower part of the glass.

When the detected glass curvature is qualified, the glass is in contact with all the lower ejector rods 6 and the upper ejector rods 9. When it is unqualified, some of the lower ejector rods 6 and the upper ejector rods 9 are not in contact with the glass. The contact is monitored by the first pressure sensor 5 and the second pressure sensor 8, and the signals are transmitted to the display 10 by the first pressure sensor 5 and the second pressure sensor 8. The first pressure sensor 5 and the second pressure sensor 8 display the first pressure sensor 5 on the display 10. The curvature of the glass can be directly detected by the pressure change detected by the second pressure sensor 8. Through the detection device, the curvature of the glass can be quickly detected, which effectively improves the detection efficiency of the curvature of the glass. When it is necessary to control the lifting and lowering of the lifting frame 7, the motor 16 drives the first reversing gear 15 to rotate through the second reversing gear 17, and the first reversing gear 15 drives the rotating frame 13 to rotate. The rotating frame 13 is threadedly connected with the screw rod 14, so that the screw rod 14 drives the lifting frame 7 to be lifted and lowered.
