Abstract

The invention relates to a device and a method for cleaning a missing forme, which is suitable for a printing procedure of manufacturing a plasma display screen. In order to solve the problem of pollution of the missing forme, the device for cleaning the missing forme comprises a cleaning roller, a mechanism for driving and adjusting the cleaning roller, a release roller, a reclaiming roller, a drive motor for driving the reclaiming roller, a viscous belt and a force balancing mechanism; the viscous belt is wound on the release roller, starts from the release roller, rounds the cleaning roller and is finally connected with the reclaiming roller; the mechanism for driving and adjusting the cleaning roller can drive and adjust the cleaning roller so that the cleaning roller drives the viscous belt to be continuously stuck on the lower surface of the missing forme; and the force balancing mechanism on the upper surface of the missing forme and the viscous belt advance together to provideequilibrant for the viscous belt, that is in the advancing process, dirt on the missing forme is stuck on the viscous belt; and the reclaiming roller is driven by the drive motor so as to reclaim theviscous belt stuck with the dirt, thereby realizing continuous and effective cleaning.

Description

technical field

[0001] The invention relates to a device and a method for cleaning a missing printing plate, in particular to a device and a method for cleaning a missing printing plate in the printing process of making a plasma display (PDP screen). The invention also relates to a printing machine comprising such a device. Background technique

[0002] In the current PDP mainstream production technology, most of the structures in the front and rear substrates are produced by screen printing, and the quality of printing is an important factor affecting product performance. Therefore, in the process of PDP production, the requirement for cleanliness is not lower than 1000 grade.

[0003] However, in the screen printing process, due to static electricity and other reasons, the missing printing plate often absorbs impurities such as fibers and hairs, resulting in defective products.

[0004] Furthermore, when printing phosphor, the phosphor paste will remain on the stencil pl...
