[0037] In some embodiments, the lip 400 of the coating die 200 faces the back roller, and the distance between the lip 400 and the back roller is the GAP value. The GAP value is used to calibrate the coating gap. The GAP value has certain guiding significance for the coating operator; when the GAP value is modified or the equipment fails, the real-time change of the GAP value cannot be detected in real time, and the cause of the equipment failure cannot be analyzed by viewing previous data records.
