[0002] Glass defects refer to defects or damage on the surface of the glass, which may include scratches, spots, bubbles, etc. Glass defect detection is to ensure that the quality of the glass products produced meets the requirements and improve the reliability and safety of the products. By performing defect detection on glass products, defects, bubbles, cracks and other problems in the glass can be discovered and eliminated in a timely manner, avoiding product quality problems and safety hazards caused by defects, and ensuring the user experience and safety. At the same time, glass defect detection can also help improve production efficiency, reduce the rate of defective products, reduce production costs, and enhance corporate competitiveness. Therefore, glass defect detection is an important quality control link in the production process.

[0003] "Publication No. 'CN217305182U' A defect detection device for tempered glass production" discloses that a turntable is used to rotate multiple pieces of tempered glass and send them to the defect detector body to achieve the detection of glass surface defects. However, when the above detection device rotates the glass, the glass is easy to move or even slide when the turntable rotates. In addition, when cleaning the glass, the dust on the surface of the glass will affect the instrument's judgment of defects. After each group of glass is detected, it needs to be reloaded. The turntable at the bottom also affects the judgment of defects. Therefore, in order to solve the above problems, this application provides a glass surface defect detection device.

[0022] The following is combined with Figure 1-4 This application is described in further detail.

[0023] Embodiment 1

[0024] Reference Figure 1-4 A glass surface defect detection device includes a box body 1, a turntable 2 is rotatably arranged above the box body 1, four clamping grooves 14 are arranged through the turntable 2, two inner walls opposite to the clamping grooves 14 are slidably connected with clamping plates 15, an electric telescopic rod for driving the clamping plate 15 is arranged inside the turntable 2, the electric telescopic rod is a common device in the prior art, and a plurality of evenly distributed air suction holes 19 are arranged through the opposite side walls of the clamping plate 15, and the air suction holes 19 and the clamping plate 15 work together to clamp the glass.

[0025] The lower wall of the turntable 2 is provided with suction grooves 17 equal to the number of the clamping plates 15, and the suction grooves 17 are all connected to the sliding grooves of the nearest clamping plates 15, and the suction holes 19 are all connected to the suction pipes 16 through the suction grooves 17. An air pump 11 is fixedly provided on the upper surface of the turntable 2, and the suction pipes 16 are all provided through the turntable 2 and connected to the air pump 11. A detachable spray head 13 is provided above the turntable 2, and the spray head 13 is provided on the connecting seat on the upper wall of the turntable 2. Here, it is a common detachable handheld spray head 13, which can be removed from the connecting seat below it and the pipe can be pulled out from the connecting seat to change the position. The output end of the air pump 11 is connected to the spray head 13 through the outlet pipe 12.

[0026] Four feeding troughs 18 cooperating with the clamping grooves 14 are provided on the upper wall of the box body 1, and four supporting plates 7 cooperating with the feeding troughs 18 are provided inside the box body 1. The supporting plates 7 are connected to the bottom of the box body 1 through hydraulic cylinders 6. If the number of glasses is small and their sizes are more in line with the sizes of the supporting plates 7, they do not need to be fixed; a common clamping device can also be provided at the supporting plates 7, as long as it does not affect the functions of the clamping plates 15 and the suction holes 19.

[0027] A support base 3 is fixedly arranged inside the box 1, and a motor 4 is fixedly arranged on the upper end of the support base 3. The motor 4 is a stepping motor, and the rotating shaft of the motor 4 is coaxially fixedly connected with a rotating rod 5. The rotating rod 5 is arranged through the upper wall of the box 1 and is rotatably connected thereto. The upper end of the rotating rod 5 is fixedly connected to the lower wall of the turntable 2. The motor 4 can drive the turntable 2 to rotate at a fixed angle so as to detect different glasses.
