Problems solved by technology

[0005] However, in the above-mentioned wiping process, the roller 802 presses the wiping cloth 804 on the inkjet head 808 for cleaning. Since the inkjet head 808 is a relatively fragile part, it is easy to cause damage when it is pressed by a hard object. In addition, the wiping action Frequent, it is easy to damage the inkjet head 808 and reduce its service life

Embodiment Construction

[0020] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] see figure 2 , a schematic side view of an inkjet head wiping device 1 provided in the first embodiment of the present invention. The inkjet head wiping device 1 includes: a wiping medium 10 , a tension device and a support device 30 .

[0022] The wiping medium 10 is in direct contact with the inkjet head (detailed later) during the cleaning process, and is used to clean the dirt and residual ink on the surface of the inkjet head, so as to ensure the cleanliness of the inkjet head. The wiping medium 10 can be made of fibers in two or more directions or polymer fibers, such as polyester fibers. The fiber is bright, smooth, soft and not easy to deform, which can better protect the inkjet head.

[0023] The tension device is disposed at both ends of the supporting device 30 , each end is provided with a pair of axles 202 and one end...

Abstract

The invention relates to an inkjet head wiping device, which comprises a wiping medium, a tension device and a supporting device. The wiping device is used for cleaning the surface of the inkjet head. The tension device provides a tension to the wiping medium. The supporting device is used to support the wiping medium, and the supporting device includes a first substrate, and the first substrate has a concave portion, and the part of the wiping medium in contact with the inkjet head is located above the concave portion and is suspended. The suspended state can prevent the inkjet head from being directly pressed by hard objects, and prolong the service life of the inkjet head. The present invention also relates to a method for cleaning an inkjet head, the steps of which are as follows: providing an aforementioned inkjet head wiping device; the wiping device and the inkjet head move relative to each other so that the inkjet head is in contact with the wiping medium of the wiping device; The ink head is separated from the wiping media. The cleaning method can protect the ink-jet head while effectively cleaning the ink-jet head.

Description

【Technical field】 [0001] The invention relates to an inkjet head wiping device and an inkjet head cleaning method using the inkjet head wiping device. 【Background technique】 [0002] In recent years, people's demand for various electronic devices such as computers and portable information devices has greatly increased. The demands and applicable places of liquid crystal display devices, especially color liquid crystal display devices, are also increasing accordingly. Such a color liquid crystal display device must adopt a color filter to realize colorized image display. Among them, the inkjet method is a method of manufacturing color filters, which is to use an inkjet device to spray red, green and blue inks into multiple pixel areas on a substrate, and then dry and solidify the inks to form The process of color layer. [0003] The above-mentioned inkjet device has a plurality of inkjet heads, each inkjet head has an ink chamber and a nozzle, the ink chamber is used to te...
