[0003] At present, the mainstream manufacturers in the market design the liquid drop tank of the liquid drop device into a very long liquid drop tank, and the water flow enters the liquid drop auxiliary tank through the main water inlet, then enters through one end of the liquid drop tank, sequentially flows through the flow meter, the manual diaphragm valve and the pneumatic valve, and finally drops onto the surface of the silicon wafer through the water dripping knife.

[0004] However, the liquid drop tank structure of the mainstream liquid drop device in the market has some problems. First, the liquid drop tank is too long, which makes it very difficult for production workers to install the liquid drop tank into the equipment, and the liquid drop tank is prone to bumping, which causes trouble for the production workers during installation. Second, the liquid drop tank is also too long, and if there is no enough supporting component in the middle, it is easy to deform under the action of gravity after a long time. Finally, if only half of the track of the equipment is needed for the water dripping device operation, the water output of the water dripping knife will become very rapid, and it is easy to appear the situation of too much water dripping, which needs to adjust the water dripping control device again, and causes a certain additional workload for after-sales.
