After the photovoltaic glass is processed, it needs to be tested. The core purpose of this test is to identify potential problems in advance and ensure that it can perform stably in practical applications. Photovoltaic glass goes through transportation and warehousing processes from production to installation; Static testing can simulate the effects of the environment (such as temperature, humidity, compressive strength and internal stress) on the glass during this process, and verify whether it can still meet the processing and use requirements after long-term static storage, so as to avoid problems such as cracking and performance degradation after installation. Therefore, a photovoltaic glass manufacturing process is needed to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to provide a photovoltaic glass manufacturing process that enables the testing of photovoltaic glass for temperature, humidity, compressive strength, and internal stress.

The pressure plate extends into the base and comes into contact with the photovoltaic glass to achieve the purpose of pressure test on the photovoltaic glass. S2, Tension Test: Take out the photovoltaic glass from step S1 and place it inside the clamping mechanism. The second cylinder drives the clamping mechanism to extend and retract, thereby pulling the photovoltaic glass and achieving the purpose of tension test. S3. Humidity test: The photovoltaic glass is held in the clamping mechanism in step S2. Water is injected into the nozzle through the spray pipe. The water comes into contact with the photovoltaic glass inside the clamping mechanism to achieve the purpose of humidity test of the photovoltaic glass. S4.

S5. High-temperature test: The photovoltaic glass inside the clamping mechanism in step S4 is disassembled and placed inside the base. The photovoltaic glass inside the base drives the heating plate and heating wire to generate heat, and the heat is transferred to the inside of the photovoltaic glass to achieve the purpose of high-temperature testing of the photovoltaic glass.

[0014] The beneficial effects of this invention are: By conducting static pressure and tension tests on photovoltaic glass, it is possible to detect whether the compressive stress on the surface and the tensile stress inside the photovoltaic glass are within a safe range, thereby assessing its risk of spontaneous explosion. By simulating extreme harsh environments of high temperature and high humidity through static experiments on photovoltaic glass, the bonding stability and durability of the coating layer and the glass substrate can be verified more quickly. At the same time, the long-term reliability of the entire composite structure (film layer + photovoltaic glass) can be assessed, thereby identifying potential failure risks in advance and ensuring the performance and safety of the product throughout its life cycle. By conducting static transmittance tests on photoluminescence glass, it is possible to check whether the photovoltaic glass coating has peeled off, discolored, or whether the photovoltaic glass has crystallization, mold growth, or other problems, ensuring that its optical performance (such as transmittance) is not affected.

Humidity test: The photovoltaic glass is held in the clamping mechanism 6 in step S2. Water is injected into the nozzle 10 through the spray pipe 9. The water comes into contact with the photovoltaic glass inside the clamping mechanism 6 to achieve the purpose of humidity test of the photovoltaic glass. S4. Light transmittance test: The photovoltaic glass is held in the clamping mechanism 6 in step S2. A flashlight is used to shine a light source on the photovoltaic glass to observe the light transmittance inside the photovoltaic glass, so as to achieve the purpose of testing the light transmittance of the photovoltaic glass. S5. High temperature test: The photovoltaic glass inside the clamping mechanism 6 in step S4 is disassembled and placed into the base 2.

The heat is transferred to the inside of the photovoltaic glass to achieve the purpose of high temperature test of the photovoltaic glass. A base 2 is fixedly installed at the center of the test bench 1. The base 2 has a cavity inside, which is filled with a heating plate 7. A heating wire 8 is fixedly installed inside the heating plate 7. A bracket 11 is fixedly connected to both sides of the top of the test bench 1.

Anti-slip particles are fixedly connected to the outside of the anti-slip layer 64. A handle 65 is fixedly connected to the top end of the screw 62. When photovoltaic glass is placed inside the clamping block 61, the screw 62 drives the clamping plate 63 to move. The clamping plate 63 compresses the space inside the clamping block 61 by moving, thereby clamping the photovoltaic glass.
