Problems solved by technology

As the coating process continues, the temperature at both ends of the separator continues to rise. At the same time, due to the single-layer metal structure at both ends of the traditional separator, heat is easily conducted to the flexible substrate that is close to or attached to the separator, resulting in Flexible substrates are heated and curled, resulting in lower quality flexible functional films

Embodiment Construction

[0020] The partition plate for the coating chamber will be further described below in conjunction with the accompanying drawings.

[0021] like figure 1 and figure 2 As shown, a partition plate 10 for a coating chamber according to an embodiment includes a body 100, a first baffle plate 200 and a second baffle plate 300, wherein the body 100 includes a U-shaped groove plate 110, a first folded edge 120 and a second folded edge Side 130.

[0022] The U-shaped groove plate 110 includes a groove bottom 112 and two side walls, and a window 114 penetrating through the groove bottom 112 is provided in the middle of the groove bottom 112 . In this embodiment, the window 114 is rectangular. Usually, under the condition that the size of the coating chamber allows, the length of the window 114 (the direction in which the flexible substrate 20 moves) can be as large as possible, and the width of the window 114 usually needs to be based on the width of the area of ​​the flexible subst...

Abstract

The invention relates to a partition plate for a coating cavity. The partition plate comprises a U-shaped groove plate, a first flange, a second flange, a first baffle and a second baffle, wherein a window penetrating through the groove bottom is formed in the middle part of the groove bottom of the U-shaped groove plate; the first flange and the second flange are respectively connected with the tops of the two side walls of the U-shaped groove plate; and the first baffle and the second baffle both stretch over the U-shaped groove plate and are connected with the first flange and the second flange. The partition plate for a coating cavity provided by the invention can effectively reduce heat transfer to a flexible base material; and by adopting the partition plate for a coating cavity, a high-quality flexible functional film can be obtained.

Description

technical field [0001] The invention relates to the field of coating technology, in particular to a partition for a coating chamber. Background technique [0002] The roll-to-roll vacuum coating technology is widely used in the production of various flexible functional films, such as the production of ITO transparent conductive films, due to its advantages of high production efficiency. [0003] Roll-to-roll vacuum coating equipment usually includes a coating roller and a number of coating chambers around the coating roller. There is a partition between the coating roller and the coating chamber. There is a window in the middle of the partition. There is a target. When the flexible substrate is used as the substrate for coating, one side of the flexible substrate is wound on the coating roller and slides over the coating roller under the action of external force, while the other side of the flexible substrate is close to or attached to the separator. During coating, a larg...
