Description

[0002] Cells are generally divided into monocrystalline silicon, polycrystalline silicon, and amorphous silicon; monocrystalline silicon solar cells are the fastest-developed solar cells at present, and their structure and production process have been finalized, and the products have been widely used in space and on the ground. This type of solar cell uses high-purity monocrystalline silicon rods as raw materials; for half-cell technology, they actually cut ordinary solar cells in half; half-cell cell technology generally uses laser cutting to cut standard-specification cells into two identical half-cell cells along the direction perpendicular to the main grid of the cell, and then weld them in series; half-cell panels resist the influence of shadows better than full standard cells, and have lower packaging losses.

[0003] During the production process of half-cut cells, it is necessary to use detection and rejection equipment to inspect the surface of the half-cut cells. After program judgment or detection, the half-cut cells with surface damage and cracks are rejected to ensure the quality of the finished half-cut cells. The current technical means for detecting half-cut cells can only detect one side or one side of the half-cut cells, thus reducing the detection efficiency of the half-cut cells and the production efficiency of the half-cut cells.

At this time, the half-cut cells are inserted between the first connecting rods 5 and the second connecting rods 11, wherein the two first connecting rods 5 will rest against the bottom of the half-cut cells, and then the turntable 6 is rotated. The turntable 6 uses the first connecting rods 5 to push the half-cut cells to flip, and put the flipped half-cut cells back on the first group of transport mechanisms 2. The flipped half-cut cells are transported by the transport mechanism 2 to enter the rejection inspection machine 4 again for secondary inspection; wherein the turntable 6 rotates vertically, and the first connecting rods 5 and the second connecting rods 11 are vertical, until the first batch of half-cut cells are inspected and the second batch of half-cut cells are transported to the transport mechanism 2, the turntable 6 is rotated to the direction of the second group of transport mechanisms 2, at which time the first connecting rods 5 and the second connecting rods 11 are arranged horizontally, and the first connecting rods 5 and the second connecting rods 11 are located on the upper part of the second group of transport mechanisms 2.
