Drying equipment for preparing quantum dot film

The invention discloses drying equipment for preparing a quantum dot film, and the equipment comprises a box body which is at least provided with a box door and an air suction hole; the objective table is arranged in the box body and is used for supporting a pre-drying substrate; and a heating unit which is built into the stage and heats the central position of the pre-dried substrate to a temperature higher than that of the peripheral position. The problem that the drying speed of the quantum dot solution at the center position of the substrate is lower due to uneven airflow during vacuumizing is effectively solved. 本申请公开了一种用于制备量子点膜的干燥设备，包括：箱体，所述箱体上至少设置有箱门和抽气孔；载物台，设置于所述箱体中，用于支撑预干燥基板；加热部，内置在所述载物台中，且通过加热使得所述预干燥基板的中心位置具有高于周边位置的温度。本申请有效的减缓因抽真空时，气流不均匀导致基板上中心位置处量子点溶液干燥速度更慢的问题。
