Description

Technical Field

[0001] This utility model relates to the field of auxiliary tools for the appearance inspection of photovoltaic cells, and in particular to an auxiliary tool for the appearance inspection of photovoltaic cells. Background Technology

[0002] The main function of auxiliary tools for photovoltaic cell appearance inspection is to help detect and evaluate the surface quality of the cells, ensuring that there are no defects such as cracks, scratches, bubbles, or stains that could affect their performance. These tools typically combine automation, artificial intelligence, and sensor technology to improve inspection accuracy and efficiency.

[0003] Existing technologies, such as the utility model patent with publication number CN208744636U, disclose an auxiliary tool for testing solar cells. This patent includes a receiving structure and a supporting structure. The supporting structure has a first bottom surface, a first inclined surface, and a vertical surface, while the receiving structure has a second bottom surface, a second inclined surface, and a third inclined surface. The first inclined surface is used to support the solar cell during testing, and the second inclined surface is used to receive the solar cell after testing. This utility model can reduce the occurrence of human injury, improve the accuracy and speed of testing, and ensure the quality of the solar cells.

[0004] The inventors discovered during use that existing auxiliary supports lacked specialized and standardized support and observation tools: the solar cells were arbitrarily leaned against the hard edges of the material box, resulting in poor stability, easy slippage and tipping, causing collisions between the solar cells and the material box or other solar cells, leading to secondary damage. More importantly, the lighting in the inspection environment relied entirely on workshop overhead lights or natural light, whose illuminance, color temperature, and color rendering index were unstable, and interference from shadows, reflections, and flicker made it impossible to standardize inspection criteria. The same solar cell could be judged drastically differently by quality inspectors under different lighting conditions, seriously affecting the consistency and accuracy of inspection results.

[0020] Compared with related technologies, the photovoltaic cell appearance inspection auxiliary tool provided by this utility model has the following beneficial effects:

[0021] This invention provides an auxiliary tool for the appearance inspection of photovoltaic cells. By incorporating an adjustable structure, it addresses the lack of specialized and standardized support and observation tools in existing auxiliary supports. Cells are often haphazardly leaned against the hard edges of the storage box, resulting in poor stability, easy slippage and tipping, and potential collisions with the storage box or other cells, causing secondary damage. More importantly, the lighting in the inspection environment relies entirely on workshop overhead lights or natural light, which is unstable in terms of illuminance, color temperature, and color rendering index, and is subject to interference from shadows, reflections, and flicker, making it impossible to standardize inspection criteria. The same cell may elicit drastically different judgments from quality inspectors under different lighting conditions, severely impacting the consistency and accuracy of inspection results. This device allows quality inspectors to simply touch the top edge of the cell with one finger, applying a small torque to smoothly and slowly move the cell, a process that takes approximately 1.5-2 seconds. The highly elastic, anti-static silicone or PU padding avoids inertial impacts from displacement, fundamentally eliminating the risk of microcracks, and allows for easy and rapid adjustment of the top plate's tilt angle to adapt to different inspection needs.

[0022] By designing a connection structure, the auxiliary pad can be easily and quickly replaced, greatly improving the portability of the auxiliary pad in terms of use and replacement. Attached Figure Description

The card plate 508 is engaged with the card slot 507. A spring 511 is installed inside the slide groove 509. The two ends of the spring 511 are fixedly connected to the slide groove 509 and the round rod 510 respectively. A connecting plate 504 is fixedly connected to the side of the connecting frame 506 away from the bottom plate 1. A rotating shaft 503 is fixedly connected to the upper end of the connecting plate 504 near the bottom plate 1. The rotating shaft 503 is rotatably connected to the top plate 4. The connecting frame 506 is slidably connected to the card plate 508. Both ends of the top plate 4 are fixedly connected to the lever plate 502. When the angle of the top plate 4 needs to be adjusted, pull the lever 502 to move it. The lever 502 moves the top plate 4, which in turn moves the rotating shaft 503. The rotating shaft 503 moves the connecting plate 504, which in turn moves the connecting frame 506. The connecting frame 506 slides on the arc surface of the slide rod 505.
