Description

A side-pull type single-sided film coating machine

technical field

The invention belongs to the technical field of film coating equipment, and in particular relates to a side-lifting single-sided film coating machine for partial surface coating of components.

Background technique

In industrial applications, there are a large number of components that need to be coated with specific film layers on their surfaces. These film layers can isolate the contact between the surface of the components and the external environment in which they are located, and protect the components. In addition, specific film layers can also enhance the physical properties of the components themselves, such as mechanical strength, electrical conductivity, thermal conductivity, etc. For optical components, the surface coating layer can improve its light transmission, refraction, reflection, and even diffraction performance. However, in many cases, it is not necessary to coat the entire surface of components. On the one hand, part of the surface of the component needs to maintain its original properties during application, and on the other hand, because a specific film layer is only suitable for a specific surface. . For example, for flat plate large-size grating optical elements, the grating surface needs to maintain optical diffraction properties in application, and the non-grating surface needs to enhance optical transmission performance, so only one-side coating can be applied to the non-grating surface of this type of optical element. Permeable membrane.

The current methods of coating the surface of components mainly include spray coating, spin coating, and pulling coating. Spray coating is not suitable for surfaces with high requirements on the uniformity of the film layer. The spin coating operation is complicated, the coating efficiency is low, and the components are required to withstand high-speed rotation vibration, and at the same time, it is easy to cause pollution or damage to the non-coating surface. Pull-up coating is more suitable for coating the entire surface of components. For components that only need coating on one surface, protection measures must be taken for other surfaces, which will lead to complicated operations and low coating efficiency. Therefore, there is an urgent need for single-sided coating machinery and equipment that can perform high-efficiency and high-uniformity coating on components, especially flat large-scale optical components.
