Fragmentation prevention device and solar cell sorting system

The utility model discloses a fragment prevention device and a sorting system of solar cell pieces, the fragment prevention device is arranged on the sorting system of the solar cell pieces, and the sorting system comprises a conveying unit used for conveying the solar cell pieces and a testing unit located on a conveying path of the conveying unit. The testing unit comprises a first end and a second end, the direction of the first end pointing to the second end is the same as the conveying direction of the conveying unit, and the fragment prevention device comprises a detection piece arranged at the first end and used for detecting whether a solar cell is located at the first end or not; the stop operation control end is used for controlling the test unit to stop working; and the delay closing piece is connected between the output end of the detection piece and the operation stopping control end. According to the scheme, whether the battery pieces are skewed and clamped can be judged, the fragmentation rate
