Embodiment 1

[0015] Example 1: The specific operation process of a small device for pulling and coating

[0016] The first step: if figure 1 As shown, the production device is installed, and the various pipelines between them can be disassembled and can be installed in a sealed manner. Connect the bottom of the liquid storage bottle 4 to one end of the mechanical pump 5 , and the other end of the mechanical pump 5 extends into the coating container 1 through the opening of the coating container cover 2 through the pipeline. The outlet end of the coating container 1 is connected with a liquid storage bottle 4 through a valve 3 . Connect the devices in this order;

[0017] Step 2: Open the coating container cover 2, place the substrate 6 in the coating container 1 and pour the prepared plating solution (the substrate 6 can be fixed with a clip, or a bracket can be fixed in the coating container 1 in advance , to fix the substrate 6 on it, etc.), then cover the coating container cover 2 an...

Abstract

The invention relates to a small lifting film coating device and belongs to the technical field of a film coating device. Mainly, a circular loop is formed by a film coating container, a film coating container cover with an inlet, a valve, a liquid storage bottle and a mechanical pump through pipelines; the bottom of the liquid storage bottle is provided with a water outlet; the water outlet at the bottom of the liquid storage bottle is communicated with the film coating container by the mechanical pump through the inlet of the film coating container cover with the inlet; the bottom of the film coating container is provided with a liquid outlet; the outlet of the film coating container is connected with the liquid storage bottle; and the valve is arranged between the film coating container and the liquid storage bottle. The device has a simple structure, utilizes a liquid level free descending manner to replace a conventional substrate lifting or film coating container descending manner, can avoid mechanical vibration and is low in cost.

Description

technical field [0001] The invention belongs to the technical field of film coating devices, and in particular relates to a small device for pulling a film. technical background [0002] With the development of industry, more and more industries need to coat the carrier to achieve specific performance. The method of coating by dipping and pulling is a traditional coating method. The dipping and pulling method is to immerse the entire cleaned substrate in the pre-prepared sol, and then pull the substrate out of the sol at a precisely controlled uniform speed, and form a layer on the surface of the substrate under the action of viscosity and gravity. Uniform liquid film, followed by the rapid evaporation of the solvent, so the sol attached to the surface of the substrate gels rapidly to form a gel film. [0003] Due to the convenient method and simple equipment, the dipping and pulling method has broad application prospects, such as the preparation of the absorbing layer film...
