Embodiment Construction

[0032] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the invention may be practiced. The directional terms mentioned in the present invention, such as [top], [bottom], [front], [back], [left], [right], [inside], [outside], [side], etc., are only for reference The orientation of the attached schema. Therefore, the directional terms used are used to illustrate and understand the present invention, but not to limit the present invention. In the figures, structurally similar elements are denoted by the same reference numerals.

[0033] The present invention is aimed at the existing transfer plate cleaning device. Since the transfer plate is suspended and cleaned, residual cleaning solvent remains at the bottom of the APR plate, which will cause cracks at the bottom of the APR plate after drying, thereby affecting the effect of subsequent PI liquid printing. . This embodiment can solve this de...

Abstract

The invention provides a transfer printing plate cleaning device which comprises a spraying mechanism, a wiping mechanism, an ultrasonic cleaning mechanism, an air blowing mechanism and a conveying mechanism. The spraying mechanism comprises a spraying groove and a spraying component. The wiping mechanism comprises a wiping part. The spraying component comprises first spray heads, the first sprayheads are arranged in the vertical direction, and the wiping part is arranged transversely. Suspension cleaning is changed into flat cleaning, and liquid is prevented from staying at the bottom of a transfer printing plate; meanwhile, through combination of the wiping mechanism, the ultrasonic cleaning mechanism and the air blowing mechanism, and a better cleaning effect and drying effect are achieved; and the situation that the liquid is left on the transfer printing plate to influence the effect of subsequent PI liquid printing is avoided.

Description

technical field [0001] The invention relates to the technical field of cleaning a transfer plate, in particular to a cleaning device for a transfer plate. Background technique [0002] In the production process of the liquid crystal display panel, in order to make the liquid crystal molecules can be correctly oriented, it is necessary to coat a layer of polyimide (PI) film on the surface of the array substrate and the color filter substrate (CF), and then carry out the process on the PI film. Rubbing treatment to achieve alignment of liquid crystal molecules. Coating PI film on the array substrate and color filter substrate generally adopts efficient transfer printing plate (APR plate) transfer printing technology. [0003] After the transfer printing is completed, a certain amount of PI liquid usually remains on the transfer printing board, which makes the transfer printing board need to be cleaned before it can be used for transfer printing again. In the prior art, when ...
