Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic glass, and in particular to a testing device and a testing method for light transmittance of photovoltaic glass. Background Art

[0002] Photovoltaic glass, also known as "photoelectric glass", is a special glass that uses solar radiation to generate electricity and has related current lead-out devices and cables. Photovoltaic glass is composed of glass, solar cells, film, back glass, special metal wires, etc. It is widely used, such as solar smart windows, solar pavilions and photovoltaic glass building ceilings, as well as photovoltaic glass curtain walls. It is divided into two categories: crystalline silicon photovoltaic glass and thin-film photovoltaic glass. The former is further divided into monocrystalline silicon and polycrystalline silicon, and is often used as curtain wall material. At the same time, the transmittance of photovoltaic glass will be tested before it is put into use.

[0003] At present, when testing the transmittance of photovoltaic glass, a transmittance testing device is used. During operation, the photovoltaic glass is placed on the test bench of the testing device, and the photovoltaic glass is fixed at the test port. After startup, the test light source is close to the photovoltaic glass at the same time, and the light source passes through the photovoltaic glass into the test port. The transmittance of the photovoltaic glass is finally obtained by calculation. In the prior art, when testing, the photovoltaic glass is constantly moved to perform tests at multiple positions to improve the accuracy of the results. However, when changing the test position, the photovoltaic glass is usually manually released first, and then the position is adjusted, and then fixed, and finally a new round of tests is performed. The manual operation steps are cumbersome and easily lead to low work efficiency. To this end, we propose a test device for the transmittance of photovoltaic glass. Summary of the invention

[0036] A method for testing the light transmittance of photovoltaic glass comprises the following steps:

[0037] S1: Pre-treat the photovoltaic glass to be tested, clean and wipe its surface, so that the photovoltaic glass meets the test standard of light transmittance;

[0038] S2: placing the photovoltaic glass block on the multiple sets of flexible disks 7 and lightly pressing them so that the photovoltaic glass is located above the test seat 4;

[0039] S3: Control the moving component 5 to operate, and the moving component 5 drives the moving light source seat 3 to move downward in the stand 2 until the test head of the moving light source seat 3 contacts the photovoltaic glass. When the two are in contact, the moving light source seat 3 continues to move downward, and the moving component 5 drives the support tube 6 to move downward at the same time, and drives the photovoltaic glass to move downward through the flexible disk 7, until the bottom end of the photovoltaic glass moves to the top end of the test seat 4. At this time, the test head of the moving light source seat 3 and the test seat 4 are respectively located above and below the photovoltaic glass, and are in a close contact state;

[0040] S4: While the moving component 5 is operating, the adsorption component 9 follows the operation. When the test head of the mobile light source holder 3 and the test holder 4 are close to the photovoltaic glass, the sliding shaft 10 in the support tube 6 is slightly pulled downward, so that the photovoltaic glass is adsorbed on the flexible disk 7, so as to prevent the photovoltaic glass from moving slightly during detection, thereby affecting the test data and improving the stability during detection;

[0041] S5: Control the mobile light source seat 3 to operate, the light source is emitted from the test head at the bottom of the mobile light source seat 3, passes through the photovoltaic glass and finally enters the test seat 4, at this time the current transmittance data is recorded;

[0042] S6: Control the moving component 5 to operate in the reverse direction again. At this time, the moving light source seat 3 moves upward. At this time, the photovoltaic glass is released from the current fixation, and the photovoltaic glass is directly replaced at the position directly above the test seat 4. After the replacement is completed, the above S1-S5 steps are repeated again to record multiple sets of data.

[0043] In a specific implementation manner, the photovoltaic glass to be tested is pretreated, its surface is cleaned and wiped clean, so that the photovoltaic glass meets the test standard of transmittance, the photovoltaic glass block is placed on multiple sets of flexible disks 7, so that the photovoltaic glass is located above the test seat 4, and the motor 22 is controlled to operate. The motor 22 drives the rotating shaft 16 to rotate through the coupling 23, and the rotating shaft 16 then drives the first threaded rod 12 above to rotate, and the first threaded rod 12 is connected to the threaded connection with the mobile light source seat 3, and then drives the mobile light source seat 3 to move downward on the stand 2, and the lower movable plate 13 slides downward in the stand 2 at the same time, and through the cooperation of the connecting rod 14, the lower pressure plate 15 at the bottom is pushed downward, and the lower pressure plate 15 moves downward along the rotating shaft 16. Move until the bottom surface of the lower pressure plate 15 contacts with the matching plate 17, and pushes it downward while continuing to move. At this time, the test head of the mobile light source seat 3 contacts with the photovoltaic glass at the same time, and the matching plate 17 squeezes the spring 18 when being driven to move downward, and drives the annular plate 8 to move at the same time. The annular plate 8 drives multiple groups of support tubes 6 to move downward on the test bench 1. Through the cooperation of the resistance block 11, the support tube 6 pushes the sliding shaft 10 downward at the same time. At this time, the mobile light source seat 3 moves closely to the photovoltaic glass until the bottom end of the photovoltaic glass moves to the top of the test seat 4, and the top of the flexible disk 7 is at the same height as the top of the test seat 4. At this time, the test head of the mobile light source seat 3 and the test seat 4 are respectively located above and below the photovoltaic glass, and the three are in a close contact state;

[0044] During the rotation of the rotating shaft 16, the first gear 33 is driven to rotate, and the second gear 34 is meshed with the first gear 33, and the second gear 34 then drives the second threaded rod 31 to rotate. Through the threaded connection between the second threaded rod 31 and the rectangular sleeve 32, the second threaded rod 31 drives the rectangular sleeve 32 to slide downward in the fixed frame 30 when it rotates. When the test head of the mobile light source seat 3 and the test seat 4 are in close contact with the photovoltaic glass, the pressing block 35 at the bottom end of the rectangular sleeve 32 presses the control switch 25. Since the control switch 25 is electrically connected to the electric telescopic rod 24, the electric telescopic rod 24 is electrically connected to the electric telescopic rod 24. During operation, the long strip 26 is pulled downward through the output end, and the tension spring 28 is stretched at this time. At the same time, the long strip 26 pulls the connecting frame 27 downward, and the connecting frame 27 pulls multiple sets of sliding shafts 10 downward at the same time. At the same time, the flexible disk 7 is close to the photovoltaic glass. At this time, suction is applied in the support tube 6, and the photovoltaic glass is adsorbed through the flexible disk 7, so as to stabilize the position of the photovoltaic glass during detection, thereby avoiding affecting the test data, and controlling the mobile light source seat 3 to operate. The light source is emitted from the test head at the bottom of the mobile light source seat 3, passes through the photovoltaic glass and finally enters the test seat 4, and the current transmittance data is recorded at this time.

[0045] It is worth noting that after the current data test is completed, the mobile component 5 is controlled to operate in reverse as a whole. At this time, the mobile light source seat 3 moves upward. At this time, the photovoltaic glass is released from the current fixation, and the photovoltaic glass is directly replaced in the position directly above the test seat 4. After the replacement is completed, the above steps are repeated again to record multiple sets of data.
