The rotating roller 6 is slidably connected to the inner wall of the powder outlet box 4, so that the rotation of the rotating roller 6 is unrestricted and can block most of the powder. A fixed box 8 is provided on the top of one side of the detection box 1. The fixed box 8 is provided with a moving component 9 to facilitate the movement of the rubber scraper 5. The moving component 9 facilitates the horizontal movement of the rubber scraper 5 on the surface of the glass plate 2.

[0023] The clamping assembly 3 includes two clamping plates 301, which are respectively disposed on both sides of the glass plate 2. An electric push rod 302 is provided on the top of the other side of the detection box 1. The telescopic rod of the electric push rod 302 passes through the detection box 1 and is fixedly connected to one side of the clamping plate 301 on the left side. A support plate 304 is provided in the middle of one side of the clamping plate 301 on the right side, and one side of the support plate 304 is fixedly connected to the inner wall of the detection box 1. By extending the telescopic rod of the electric push rod 302, in conjunction with the right clamping plate 301, the glass plate 2 can be clamped and fixed.

[0024] Two guide rods 303 are symmetrically arranged on one side of the left clamping plate 301. One end of the guide rod 303 passes through the detection box 1 and extends to the outside of the detection box 1. A rubber pad is provided between the two clamping plates 301 and the glass plate 2. The guide rods 303 enable the left clamping plate 301 to play a limiting and guiding role when moving.

[0025] The moving component 9 includes a lead screw 901, which is rotatably mounted inside the fixed box 8. A slide 902 is threadedly connected to the surface of the lead screw 901 via a lead screw nut, and the slide 902 is slidably connected to the inner wall of the fixed box 8. An electric push rod 903 is provided at the middle of the top of the slide 902. The telescopic rod of the electric push rod 903 passes through the slide 902 and is provided with a moving block 904. One side of the moving block 904 is fixedly connected to one side of the powder box 4. By rotating the lead screw 901 in both directions, in conjunction with the lead screw nut, the slide 902, the moving block 904, the fixed box 8, and the rubber scraper 5 can be moved horizontally. In conjunction with the electric push rod 903, the rubber scraper 5 can be moved vertically, which is convenient for testing glass plates 2 of different thicknesses.

[0026] Guide posts 905 are provided on both sides of the top of the movable block 904. The top of the guide post 905 passes through the slide 902 and extends to the top of the slide 902, so that the movable block 904 plays a limiting and guiding role during the up and down movement.

[0027] The powder dispensing box 4 has an open hopper 12 at the top for easy addition of powder. The powder is made of talcum powder, which is fine enough to remain on the defects of the glass plate 2, making the defects of the glass plate 2 obvious. A stepper motor 10 is provided at the bottom of one side of the powder dispensing box 4. The output shaft of the stepper motor 10 passes through the powder dispensing box 4 and is fixedly connected to one end of the rotating roller 6, so that the rotating roller 6 can be driven to rotate by the stepper motor 10, so that the powder dispensing groove 7 on the surface of the rotating roller 6 can rotate and drop the powder carried by the powder dispensing groove 7.

[0028] A forward and reverse motor 11 is provided on one side of the fixed box 8. The output shaft of the forward and reverse motor 11 passes through the fixed box 8 and is fixedly connected to one end of the lead screw 901, so that the lead screw 901 can be driven to rotate in the forward and reverse directions by controlling the forward and reverse motor 11.

[0029] The testing box 1 is equipped with a guide plate 13 inside. A discharge chute 14 is opened on one side of the bottom of the testing box 1. A receiving box 15 is provided on one side of the discharge chute 14, so that the powder scraped off by the rubber scraper 5 can enter the interior of the receiving box 15 with the help of the guide plate 13, which facilitates the collection of powder and makes it convenient to add powder to the powder box 4 later.

[0030] In use, firstly, place the glass plate 2 between the two clamping plates 301, and control the extension of the electric actuator 302 to secure the glass plate 2 with the clamping plates 301. The rubber pads provide protection for the glass plate 2. Next, control the stepper motor 10 to drive the rotating roller 6 to rotate. The rotation of the roller 6 drives the powder dispensing trough 7 to rotate synchronously. The powder dispensing trough 7 carries powder, which is then precisely released onto the surface of the glass plate 2 in conjunction with the powder dispensing box 4. Then, adjust the distance between the rubber scraper 5 and the glass plate 2 as needed. Control the electric actuator 903 to move the moving block 904, the powder dispensing box 4, and the rubber scraper 5 vertically, so that the rubber scraper 5 is in contact with the surface of the glass plate 2. Then, the forward and reverse motor 11 drives the lead screw 901 to rotate forward. In conjunction with the lead screw nut, the slide 902 moves along the surface of the lead screw 901, which in turn drives the moving block 904, the powder box 4, and the rubber scraper 5 to move horizontally. The rubber scraper 5 works in tandem with the powder to smoothly and automatically scrape the surface of the glass plate 2. Once powder is found to be stuck in a certain place on the glass plate 2, it proves that there is a defect in the glass plate 2. This realizes the automatic detection and intuitive marking of defects in the glass plate 2, thereby improving the efficiency of defect detection in the glass plate 2. Compared with traditional manual inspection, it can effectively avoid the risk of missed detection and misjudgment, and ensure the quality of the final glass plate 2 product. After the inspection is completed, the glass plate 2 can be flipped over to inspect the defects on the other side of the glass plate 2.

[0031] During the process of scraping the powder, the rubber scraper 5 causes the powder to move along the surface of the glass plate 2, so that the excess powder enters the receiving box 15 through the guide plate 13 and is collected uniformly. After the inspection is completed, the glass plate 2 with powder spots is removed, the defective glass plate 2 is processed uniformly, and the powder on the glass plate 2 without defects can be further processed.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
