The invention relates to a quantitative smectic liquid crystal dripping device. The quantitative smectic liquid crystal dripping device comprises a fixing frame, a heating and conveying device and a quantitative dripping device, wherein the heating and conveying device is mounted at the left end of the fixing frame; the quantitative dripping device is mounted at the right end of the fixing frame.The quantitative smectic liquid crystal dripping device can solve the problems as follows: during dripping of a smectic liquid crystal, people usually convey and drip the heated smectic liquid crystal; in the dripping process, the liquid crystal is difficult to drip because the viscosity of the liquid crystal which is not dripped becomes large as the temperature drops, and difference in the amountof the dripped liquid crystal exists; in addition, in the dripping process, some of liquid crystal particles splash elsewhere to cause scrapping of a liquid crystal film; the quantitative smectic liquid crystal dripping device has the main advantages as follows: the conveying amount of the liquid crystal is controlled and only an amount of the liquid crystal required during current working is conveyed, so that blockage caused by increase in the viscosity of the cooled liquid crystal is avoided; the dripping amount of the liquid crystal is controlled, so that difference in the liquid crystal amount after dripping is reduced; the surrounding of the liquid crystal after dripping is sheltered, so that the liquid crystal is avoided from splashing elsewhere to affect the working process.
