[0032] Techniques, methods and devices known to those skilled in the relevant art can not be discussed in detail, but in appropriate cases, the techniques, methods and devices should be considered as part of the specification.

[0033] As mentioned in the above background, in the glass production process, the physical properties of the glass need to be tested by a testing device to ensure the quality of the glass. In order to improve the efficiency and convenience of the testing work of the physical properties of the glass, how to realize a testing device which can realize the testing of the bending strength of the glass and the testing of the impact resistance of the glass is a problem that needs to be considered by those skilled in the art. Based on this, the inventors of the present application provide a testing device for the physical properties of glass in one or more embodiments. The technical scheme of the present application realizes the testing of the bending strength and the impact resistance of the glass through the cooperation of the electromagnetic chuck, the vertical plate, the top plate, the floor, the first circular ring and the second circular ring. Thus, one or more problems in the prior art are solved.

[0034] In view of the foregoing technical problems, the utility model provides a testing device for the physical properties of glass, as shown in Figures 1-3 The testing device for the physical properties of glass comprises a base 1, two vertical plates 2, a floor 3, an electromagnetic chuck 5, and a top plate 6. The two vertical plates 2 are parallel and connected to opposite ends of the base 1. The floor 3 is arranged on the base 1 between the two vertical plates 2 and has a first circular ring 4 on the top surface. The two ends of the electromagnetic chuck 5 are slidably connected to the two vertical plates 2. The bottom surface of the top plate 6 has a second circular ring 7. The top surface of the top plate 6 can be attracted to the electromagnetic chuck 5 after being electrified, and the second circular ring 7 is directly above the first circular ring 4. The radius of the first circular ring 4 is greater than that of the second circular ring 7.

[0035] Specifically, when testing the bending strength of the glass sample 20, the glass sample 20 is first placed on the first circular ring 4. The electromagnetic chuck 5 is electrified to generate a magnetic field, and the top plate 6 is attracted to the electromagnetic chuck 5 by the magnetic field. Further, the top plate 6 is made of a metal plate, such as a steel plate. Then, the electromagnetic chuck 5 moves downward on the vertical plate 2, so that the second circular ring 7 abuts against the upper surface of the glass sample 20. The electromagnetic chuck 5 continues to move downward, so that the second circular ring 7 generates a downward pressure on the glass sample 20, and the first circular ring 4 generates an upward supporting force on the glass sample 20. Since the radii of the first circular ring 4 and the second circular ring 7 are different, the force points on the glass are different, so that a vertical shear force is generated on the glass sample 20 between the first circular ring 4 and the second circular ring 7. As the downward pressure of the second circular ring 7 on the glass sample 20 increases, the shear force on the glass sample 20 also increases, until the glass sample 20 breaks. The downward pressure on the glass sample 20 when it breaks is the bending strength.

[0036] When the impact resistance test of the glass sample 20 is performed, the electromagnetic chuck 5 is moved upward to a certain height on the vertical plate 2, the electromagnetic chuck 5 is powered on, the top plate 6 is adsorbed on the electromagnetic chuck 5, then the electromagnetic chuck 5 is powered off, the top plate 6 performs free fall, and the glass sample 20 placed on the first circular ring 4 is impacted to break the glass sample 20, and the height of the electromagnetic chuck 5 at which the glass sample 20 is broken can be regarded as a performance index of the impact resistance of the glass sample 20.

[0037] Compared with the prior art, the test device for the physical performance of the glass can adsorb the top plate 6 on the electromagnetic chuck 5 by powering on the electromagnetic chuck 5, and can abut the second circular ring 7 on the glass sample 20 placed on the first circular ring 4 by moving the electromagnetic chuck 5 on the vertical plate 2, and can apply a downward pressure to the glass sample 20 to realize the test of the bending strength of the glass sample 20; the top plate 6 adsorbed on the electromagnetic chuck 5 performs free fall downward by powering off the electromagnetic chuck 5 to realize the test of the impact resistance of the glass sample 20. The test device of the disclosure can realize the test of the bending strength of the glass and the test of the impact resistance, and improves the efficiency and convenience of the test of the physical performance of the glass.
