[0002] Solar photovoltaic system refers to the facilities that use the photovoltaic effect of photovoltaic semiconductor materials to convert solar energy into direct current electricity. The core of photovoltaic facilities is solar panels, which include solar cells.

[0003] After the battery cell passes the test, the next production process is carried out. When the battery cell is tested, the lead on the battery cell is clamped between the test ends and powered on for testing. In the existing testing work, when the battery cell is placed, the battery cell has a certain weight, and the battery cell hard contacts the tooling, which has a large recoil force on the battery cell.

[0004] In view of this, we propose a detection tool for photovoltaic solar cells. Utility Model Content

After the battery cell to be tested is placed on the U-shaped plate B, the compression of the buffer spring cooperates with the contraction of the telescopic rod body to offset the impact force generated by the placement of the battery cell, thereby reducing the rebound force on the battery cell and solving the problem that the battery cell hard contacts the tooling and causes a large rebound force on the battery cell.

[0025] The utility model provides an arc-shaped spring piece and an arc-shaped rubber pad, so that when the battery cell to be tested is placed on the U-shaped plate B, it contacts the arc-shaped rubber pad, and the soft contact protects the battery cell.
