Description

Technical Field

[0002] With the rapid progress and development of photovoltaic technology, the use of thin silicon wafers to make flexible cells has received more and more attention. During the preparation process, the cells need to be carried on the carrier board and transported in the equipment of different processes; the carrier board needs to stop after transporting the cell to the position. If the carrier board is stopped urgently at this time, the inertia of the carrier board will be too large, causing the cell board to be thrown out and damaged. Therefore, a minimum safety distance needs to be reserved in advance for the carrier board to stop; the minimum safety distance refers to the minimum transmission displacement required from deceleration to uniform speed after the carrier board stops transporting (the uniform speed here means that the carrier board can stop smoothly at any time). If the minimum safety distance is inaccurate, the carrier board will exceed the minimum safety distance and hit the equipment, causing damage to the equipment and the carrier board; therefore, it is necessary to test the minimum safety distance of the carrier board at different speeds before entering the production process; in the related art, the carrier board is usually tested directly in the equipment. Due to the lack of sensing components, the safety distance is adjusted by manual observation, which has low accuracy, resulting in inaccurate safety distance test of the carrier board. In the actual working process, the carrier board will hit the equipment, causing losses;
