Description

Technical Field

[0001] The utility model relates to, in particular to, a battery pole piece coating misalignment indicating mechanism and a coating machine. Background Art

[0002] Lithium-ion battery is a secondary battery (rechargeable battery), which mainly relies on the movement of lithium ions between the positive and negative electrodes to work. The coating machine is an important process equipment for forming battery pole pieces. After drying by the coating machine, it is cut into sheets or rolled up. During the coating process, the coating film is often scrapped due to coating misalignment. At present, in order to detect the misalignment of the AB surface as early as possible, the method of using a marker pen on the coating back roller to mark the edge of the substrate of the centering film is adopted: once the coating film is misaligned as a whole, the edge of the film will cover the marking line or move away from the marking line. Employees can know whether the film has been offset too much and make timely adjustments to avoid the risk of misalignment. However, this method has many disadvantages. First, the marker pen line is easy to fade, second, the marker pen line is too thick and not accurate enough, and third, the marker pen line needs to be erased and redrawn when cutting and pulling, which requires the accuracy of the marking and is relatively time-consuming.
