Embodiment 1

[0041] This embodiment provides a transfer plate pretreatment device, such as figure 1 As shown, it includes a corresponding driving roller 1 and a pressure roller 2. The driving roller 1 includes a heating layer for heating the transfer plate 3 spread on it, and the pressure roller 2 is used for heating the transfer plate 3 spread on it. The transfer plate 3 on the driving roller 1 is pressed to improve the wettability of the transfer plate 3 .

[0042] Among them, the driving roller 1 is a cylindrical roller, and the pressing roller 2 is also a cylindrical roller. By spreading the transfer plate 3 on the cylindrical surface of the driving roller 1, and heating and extruding it, the gradient angle of the meshes of the mesh layer of the transfer plate 3 can be increased microscopically, thereby reducing macroscopically. The contact angle between the small transfer liquid and the transfer plate 3 (for example, the contact angle between the transfer plate 3 and the transfer liq...

Embodiment 2

[0061] This embodiment provides a transfer device, such as Figure 5 As shown, it includes the transfer plate pretreatment device in Example 1; it also includes a hanging plate mechanism 6 and a plate ketone 7, and the plate hanging mechanism 6 is arranged between the transfer plate pretreatment device and the plate ketone 7, and is used to transfer the transfer plate. The transfer plate 3 processed by the printing plate pretreatment device is hung on the printing plate 7 .

[0062] By using the transfer plate pretreatment device in Example 1, the wettability of the transfer plate 3 can be improved automatically before the transfer plate 3 is hung on the plate ketone 7, and its wettability can be increased, so that the The transfer device can automatically improve the wettability of the transfer plate 3 before hanging the plate, thereby improving the hanging efficiency and the utilization rate of the transfer device.

[0063] Among them, the setting of the plate hanging mecha...

Abstract

The invention provides a transfer printing plate pretreatment device and a transfer printing device. The transfer printing plate pretreatment device comprises a driving roller and a pressure roller which are correspondingly arranged, the driving roller comprises a heating layer, the heating layer is used for heating a transfer printing plate laid on the driving roller, and the pressure roller is used for extruding the transfer printing plate laid on the driving roller, so that the wetting property of the transfer printing plate is improved. According to the transfer printing plate pretreatmentdevice, slope angles of mesh openings of a mesh opening layer of the transfer printing plate are microcosmically increased, so that contact angles between transfer printing liquid and the transfer printing plate are macroscopically decreased, the extensibility of the transfer printing plate and the elasticity of the mesh opening layer are improved, so that the mesh opening layer of the transfer printing plate is easily wetted by the transfer printing liquid, the wetting property of the transfer printing plate is improved, laying of the transfer printing liquid on the transfer printing plate is facilitated, transfer printing effects of the transfer printing liquid is improved, thickness uniformity of a coating formed after transfer printing of the transfer printing liquid is improved, wetting time of the transfer printing plate can be shortened, the operation ratio of the transfer printing plate pretreatment device is increased, and the wetting effects of the transfer printing plate can be kept for a longer time.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to a transfer plate pretreatment device and transfer equipment. Background technique [0002] The rapid development of liquid crystal display panels has become an indispensable part of people's lives. With the continuous updating of process technology and equipment, the display effect of liquid crystal display panels has been greatly improved, bringing great convenience to our life and work. [0003] The liquid crystal display panel includes a matching color filter substrate and an array substrate. An alignment film is formed on the opposite side of the color filter substrate and the array substrate. The alignment film is usually transferred to the color filter substrate and the array substrate by a transfer plate. The pros and cons of printing equipment and transfer process directly determine the quality of the formed alignment film. For example, since the transfer plat...
