When the vacuum extraction device of the photovoltaic cell laminator is used, the photovoltaic cells to be processed are first placed on the placement plate in turn, and the vacuum pump is turned on at the same time. The vacuum pump suctions the cells to be processed inside through the suction holes, thereby ensuring the vacuum inside the cells. The circular frame is then pressed down, and the air avoidance plate is driven downward by the circular frame. At the same time, the downward pressing plate and the force distribution frame are also driven downward during the downward pressing process of the air avoidance plate. When the force distribution frame contacts the cells inside the placement plate, it continues to press down to perform cell lamination. During the lamination process, the vacuum pump gradually extracts the compressed gas inside the cell to maintain the vacuum state inside the cell. At the same time, the structure of the force distribution frame is a layered tower, which can gradually increase the downward pressure to make the force uniform, thereby avoiding uneven lamination of photovoltaic cell components and quality problems such as bubbles and stratification.
