The invention relates to a clip, which is suitable for being arranged on a slit type coating head to change the coating width. The clip includes a first board part, a second board part and a third board part. The second plate portion and the third plate portion are connected to the first plate portion and protrude toward the same direction. The second plate part is spaced apart from the third plate part to form a main channel, and the main channel is used for connecting a first branch pipe of the slit type coating head. The second plate portion has a first flow channel. The first branch channel has an open end and a closed end opposite to each other. The open end is connected to the main channel, and the shortest distance from the open end to the first plate portion is greater than the shortest distance from the closed end to the first plate portion. The second plate portion is used to cover a part of the first branch pipe, and the closed end of the first flow channel is used to expose another part of the first branch pipe. In addition, the present invention also relates to a slot coater using the aforementioned clip.
Description
technical field [0001] The invention belongs to the technical field of film coating, and relates to a clip and a slit coater, in particular to a clip with a flow channel and a slit coater using the same. Background technique [0002] Precision coating technology is an important development direction of thin film technology in the future. Among many coating technologies, slot die coating technology is one of the most widely used and has deep development potential. In recent years, due to the rise of the electronics industry, the requirements for film uniformity have become more stringent. [0003] However, the conventional slit coater has the problem of causing coating defects when using a clip shutter for different coating widths. In detail, according to the different widths to be coated, a clip shutter is generally set in the slit coating head to block a part of the shunt pipe (or flow channel) in the coating head, thereby changing The width of the paint that can flow out...
