Silicon wafers are the carriers of solar cells. The quality of silicon wafers directly determines the conversion efficiency of solar cells. Therefore, it is necessary to detect the incoming silicon wafers. This process is mainly used to measure some technical parameters of silicon wafers online. These parameters mainly include mechanical load of silicon wafers, surface roughness, minority carrier life, resistivity, P / N type and microcracks. This group of equipment is divided into automatic loading and unloading, silicon wafer transmission, system integration and four detection modules.

[0003] However, when the current device is testing photovoltaic panels, due to the different sizes of photovoltaic panels, it is impossible to fix photovoltaic panels of different specifications, resulting in a single practical range of the device. At the same time, after the current device fixes the photovoltaic panels, it uses manual methods to push them for testing, which wastes manpower to a certain extent. Therefore, it is necessary to design a dynamic mechanical load tester. Utility Model Content

While the bidirectional threaded shaft 7 rotates, the first clamping plate 8 and the second clamping plate 9 can be driven to slide using the sliding rod 11, so that the photovoltaic panel can be fixed. This setting can use photovoltaic panels of different specifications for fixing, which increases the practicality of the device during testing.

[0025] In this embodiment, a slide bar 11 is fixedly connected to one side of the inner wall of the support seat 6 , and the first clamping plate 8 and the second clamping plate 9 are both slidably connected to the slide bar 11 .

[0026] During specific use, when making adjustments, the first clamping plate 8 and the second clamping plate 9 can slide using the slide rod 11, thereby facilitating the adjustment.

[0027] In this embodiment, a latch 12 is slidably connected to one side of the outer surface of the support seat 6 , and a second turning handle 13 is fixedly connected to one side of the outer surface of the rotating shaft 5 .

[0028] During specific use, when reversal is required, pull out the pin 12 and hold the second handle 13 by hand to drive the support base 6 to rotate. After reaching the appropriate position, insert the pin 12 again to fix it, which is convenient for detecting the back of the photovoltaic panel.

[0029] In this embodiment, a first servo motor 14 is fixedly connected to one side of the lower surface of the detection frame 2 , a telescopic shaft 15 is fixedly connected to the output end of the first servo motor 14 , and a detection block 16 is fixedly connected to one side of the lower surface of the telescopic shaft 15 .

[0030] During specific use, when the photovoltaic panel needs to be inspected, the first servo motor 14 is started to drive the telescopic shaft 15 to extend and retract. During the extension and retraction of the telescopic shaft 15, the detection block 16 can be brought close to the surface of the photovoltaic panel, so that the photovoltaic panel can be inspected.

[0031] In this embodiment, a connecting plate 17 is fixedly connected to one side of the inner wall of the frame 4 , and a fixing plate 18 is fixedly connected to one side of the upper surface of the bottom plate 1 .

[0032] During specific use, the connection plate 17 is provided to facilitate supporting the threaded rod 20 , and the fixing plate 18 can support the second servo motor 19 .

[0033] In this embodiment, a second servo motor 19 is fixedly connected to one side of the outer surface of the fixing plate 18 , and a threaded rod 20 is fixedly connected to the output end of the second servo motor 19 .

[0034] When in use, the second servo motor 19 is started to drive the threaded rod 20 to rotate, and the frame 4 can be driven to slide while the threaded rod 20 rotates.

[0037] Working principle: in use, before testing, when the photovoltaic panel needs to be fixed, the photovoltaic panel is pressed tightly against the first clamping plate 8 and the second clamping plate 9, and then the first turning handle 10 is held by hand and rotated, which can drive the bidirectional threaded shaft 7 to rotate. While the bidirectional threaded shaft 7 rotates, the first clamping plate 8 and the second clamping plate 9 can be driven to slide using the slide bar 11, so that the photovoltaic panel can be fixed. This setting can be used to fix photovoltaic panels of different specifications, which increases the practicality of the device during testing. After fixing, start the second servo motor 19, which can drive the threaded rod 20 to rotate. While the threaded rod 20 rotates, it is convenient for the frame 4 to move in the slide rail 3, so that the frame 4 can be moved to the test position. The bottom of the frame 2 greatly reduces the labor force. When the photovoltaic panel needs to be inspected, the first servo motor 14 is started, which can drive the telescopic shaft 15 to extend and retract. During the extension and retraction of the telescopic shaft 15, the detection block 16 can be close to the surface of the photovoltaic panel, so that the photovoltaic panel can be inspected. After the inspection is completed, the second servo motor 19 is started in the same way, which can drive the threaded rod 20 to reverse. While the threaded rod 20 rotates, it is convenient for the frame 4 to move in the slide rail 3, so that the frame 4 can move. When reversal is required, the pin 12 is pulled out, and the second handle 13 is held by hand to drive the support seat 6 to rotate. After reaching the appropriate position, the pin 12 is reinserted to fix it, which is convenient for inspecting the back of the photovoltaic panel.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
