[0002] At present, the automatic docking and cutting of coating machine is widely used in the field of precision coating machines, especially in the field of relatively high-end polarizing films. Since polarizing film materials are expensive, the cut heads of this product are usually not allowed to overlap, which will produce a lot of waste. The traditional method uses manual docking, but the manual docking takes too long and sometimes requires downtime, which is too inefficient. In addition, polarizing films have high requirements for cleanliness, usually reaching a hundred-level precision. If this mechanism uses a sawtooth chopper structure, it cannot meet the cleanliness requirements and affect product quality. Summary of the invention
