1. Introduction
Filter membrane is a widely used functional material, which is widely used in electronic products, medical devices, biological experiments and other fields. In these applications, the quality of the membrane has a direct impact on the performance and longevity of the product. Therefore, how to evenly and efficiently coat the filter membrane on the substrate material has become an important research topic.
The automatic film coating machine is a kind of equipment that can realize the automation of the coating process, which has the advantages of fast coating speed and high coating uniformity.
