Problems solved by technology

The biggest disadvantage of this solution is that the design of this device greatly limits its moving speed, which makes the film removal speed very slow. Usually, the film removal speed of this solution is 10-20mm / sec
The process opening of the film removal device is very narrow, and there are often large residues in the film removal area after film removal, and burrs and relatively large accumulations often appear on the edges of the film after film removal. These shortcomings greatly limit its use in quantity. Application in production

Embodiment 1

[0049] Such as figure 1 As shown, the selective membrane removal device of the present invention includes a membrane removal head (110), a liquid outlet device (120), a liquid removal device (130), a positioning device (140) and a displacement device (150). The membrane head (110) is installed on the positioning device (140), and the positioning device (140) is installed on the displacement device (150).

[0050] Described film removal head (110) comprises liquid outlet pipe (240) and liquid removal pipe (230), and liquid removal pipe (230) wraps liquid outlet pipe (240), and described liquid outlet pipe (240) includes liquid outlet pipe (240) Pipe inlet (240a) and liquid outlet pipe outlet (240b), described liquid removal pipe (230) comprises liquid removal pipe inlet (230a) and liquid removal pipe outlet (230b), described liquid outlet device (120) and The liquid outlet pipe inlet (240a) is connected, and the liquid removal device (130) is connected with the liquid removal ...

Embodiment 2

[0065] Example 2 studies the influence of production beat on the selective membrane removal device. Production tact is a very important indicator in industrial production. The value of production tact reflects the current production capacity of the system. The smaller the value, the shorter the time required to produce a single workpiece and the stronger the production capacity; on the contrary, the value The larger it is, the longer it takes to produce a single workpiece and the worse the production capacity. The production tact is determined according to the output requirements. When the production tact of the entire assembly line of a production process is determined, each process of the process assembly line must meet the requirements. Therefore, for a fixed production cycle, the design and diameter of the outlet of the liquid outlet and the inlet of the liquid removal pipe of the selective film removal device, the moving speed of the film removal head and the number of th...

Embodiment 3

[0071] Example 3 studies the influence of the ratio of the residual area to the membrane removal area on the selective membrane removal device. figure 2 The pattern of the thin film after film removal and the residue of the film removal area are schematically shown. 310 is the substrate, 320 is the film to be processed, 330 is the film removal area of ​​the film to be processed, and 340 is the remaining film after film removal of the film to be processed. Define the area of ​​the film remaining after film removal as S1, the total area of ​​the film removal area as S0, and the ratio of the remaining area to the total area of ​​the film removal area P=S1 / S0. Different processes have different requirements for P. Some processes have low requirements for P, and p<50% is sufficient, but many processes have high requirements for P. For example, in OLED mass production processes, many wet coatings are selectively After removing the film, p<5% is required. This is because the encaps...

Abstract

The invention provides a selective membrane removing device. The membrane removing device comprises a membrane removing head, a liquid discharge device, a liquid removing device, a positioning device and a displacement device, wherein the membrane removing head is installed on the positioning device which is installed on the displacement device; the membrane removing head comprises a liquid discharge pipe and a liquid removing pipe; the liquid discharge device is connected with the liquid discharge pipe of the membrane removing head; the liquid removing device is connected with the liquid removing pipe of the membrane removing head; the liquid discharge pipe wraps the liquid removing pipe, or the liquid removing pipe wraps the liquid discharge pipe. The selective membrane removing device has the following technical effects: firstly, a very wide technological window can be obtained by utilizing the device; secondly, the membrane removing speed range can be increased to 5-300mm / sec, and the membrane removing speed is almost 8 times and more that of the prior art; thirdly, the membrane removing effect is good, no residue or very micro residue exists at the membrane removing region after membrane removal, and no stacking or very small stacking exists on the edge of the membrane removing region, so that the selective membrane removing device can be truly applied to a mass production technology.

Description

technical field [0001] The invention relates to a selective film removal device which performs selective film removal in a coating process or cooperates with coating equipment to realize selective coating, and belongs to the technical field of coating. Background technique [0002] There are some precision coating processes in the production processes of semiconductors, solar cells, liquid crystal panels, LED lighting, OLED displays, OLED lighting, etc. These coating processes are different from general full-surface coating processes but require pattern coating , that is, the coated film is arranged according to a certain pattern distribution, and this type of coating is usually called selective coating or selective film formation. Taking the OLED mass production process as an example, there are some selective coating processes as follows, such as using a slit coater to coat the liquid hole injection layer film, and using a spin coating device to coat the internal light extr...
