The reset spring between the pull rod 15 and the inner wall of the square cavity 14 is used to reset the pull rod 15 when the pull rod 15 is not affected by pulling force. The bottom wall of the detection box 2 is fixedly connected with two guide rails 5, the guide rails 5 are rotatably connected with threaded rods 7, the outer surfaces of the threaded rods 7 are threadedly connected with moving blocks 6, the moving blocks 6 are slidably connected with the guide rails 5, one end of the moving blocks 6 is fixedly connected with the placement plate 4, the bottom wall of the detection box 2 is fixedly connected with two air bags 16, the air bags 16 contain a large amount of gas, the upper surface of the air bag 16 is fixedly connected with a gas injection cavity 17, the gas injection cavity 17 is provided with a plurality of gas injection holes, the bottom wall of the detection box 2 is fixedly connected with a partition plate 3, the partition plate 3 divides the detection box 2 into two areas, which are a to-be-detected area and a sample area, the sample area is provided with a sample glass, and the to-be-detected area is provided with a to-be-detected glass. The inner wall of the detection box 2 is fixedly connected with two detection display instruments 23, the detection display instruments 23 are prior art and can receive reflected radiation, the outer surface of the partition plate 3 is fixedly connected with two radiation light sources 24, the radiation light sources 24 are prior art and can emit radiation to the to-be-detected glass.

[0026] In this invention, during use, the sample glass is first placed on the placement plate 4 of the sample area in the testing chamber 2. Simultaneously, the glass to be tested is placed on the suction cup 9 of the placement plate 4 in the testing area. Pressing down on the glass causes the suction cup 9 to deform under pressure, increasing the internal gas pressure of the cylinder 8 and the suction cup 9, thus firmly holding the glass in place. Then, by rotating the threaded rod 7, the threaded rod 7 moves the placement plate 4 via the moving block 6 until the placement plate 4 reaches the testing position. Rotating the threaded rod 7 then stops, preventing the glass to be tested from colliding with the testing chamber 2 and ensuring stable fixation. When removal is required, the threaded rod 7 is rotated in the opposite direction, causing the placement plate 4 to move out of the testing chamber 2. Pulling the lever 15 causes the push rod 13 to move the squeezing block 12. The squeezing block 12 moves and causes the air blocking block 11 to rotate. At this time, the air outlet on the surface of the cylinder 8 is exposed, and the gas pressure inside the cylinder 8 and the suction cup 9 decreases. The suction cup 9 loses its suction effect, and the glass to be tested can be easily removed from the placement plate 4. This eliminates the need for the testing worker to perform tedious disassembly, saving the testing worker's time and improving work efficiency. The sample glass is fixed in the same way. After completing the preparation work, the radiation source 24 is turned on, and the testing display instrument 23 is observed. The test data of the sample glass and the glass to be tested are compared to obtain the test results and determine whether the glass to be tested is qualified.

[0027] The movement of the placement plate 4 drives the rack plate 21 to move, which in turn drives the spur gear 20 to rotate. The rotation of the spur gear 20 drives the reciprocating screw 19 to rotate, which in turn drives the brush plate 22 to move horizontally on the glass to be tested and the sample glass, cleaning foreign objects and dust from the glass to be tested and the sample glass, thus preventing these foreign objects and dust from affecting the test results. At the same time, as the placement plate 4 moves and is about to reach the test position, the placement plate 4 will squeeze the air bladder 16. The gas in the air bladder 16 is subjected to pressure and acts on the surface of the glass to be tested, the sample glass, and the brush plate 22 through the jet chamber 17, cleaning the dust on them and improving the overall cleaning ability of the device. This ensures that the brush plate 22 remains clean during each operation. After the test is completed, the placement plate 4 is removed from the test chamber 2. At this time, the air bladder 16 is no longer subjected to pressure and returns to its original state. At the same time, external gas is drawn into the air bladder 16 through the jet chamber 17, thus preparing for the next cleaning operation.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.
