[0002] Photovoltaic coated glass is a special glass used in photovoltaic modules. Tensile stress refers to the stress generated when an object is stretched, and compressive stress refers to the stress generated when an object is compressed. In photovoltaic coated glass, tensile stress and compressive stress usually exist simultaneously. In practical applications, the four-point bending test device usually requires the following technologies:

[0003] 1. Loading system: the loading roller is used to apply downward pressure, and the supporting roller is used to support the glass sample;

[0004] 2. Support system, consisting of two support rollers or support seats, used to support the test sample;

[0005] 3. Measurement system, including force sensor and displacement sensor, used to measure the loading force and deformation of the test sample;

[0006] 4. Sample fixture, used to fix the glass sample to ensure that the sample does not slide or move during the test.

[0007] At present, the existing four-point bending test device (such as patent publication number: CN219455791U) discloses a four-point bending test device, in which the first drive mechanism is arranged in the cavity of the first mounting seat, which can protect the first drive mechanism; the slide groove is arranged on the two side walls of the first mounting seat and connected to the cavity, and the top of the first mounting seat maintains a smooth plane. The residue of the test article formed during the bending test falls on the smooth plane for easy cleaning.
