A coating die and a coating apparatus

Abstract

The application relates to a coating die and a coating device, the coating die comprising a coating main body and an exhaust passage, an internal part of the coating main body is formed with a liquid storage cavity, the liquid storage cavity has a first end and a second end which are oppositely arranged along a first direction, the first end is provided with a coating slit, and the second end is provided with a first position which is communicated with the exhaust passage; wherein the first position is located at least one side edge of the second end along a second direction which intersects the first direction, and the distance between the first position and the coating slit is greater than the distance between other positions on the second end and the coating slit in the first direction. The slurry in the application fills the liquid storage cavity from bottom to top under the action of gravity, so that the gas can be more smoothly discharged from the first position which is the highest point through the exhaust passage, the exhaust in the liquid storage cavity is more thorough, and the coating quality is effectively improved.
