Problems solved by technology

However, in the structure of the existing cleaning device as described above, from the beginning to the end of the wiping cleaning of the terminal portion, the same portion of the cleaning cloth is in contact with the terminal portion, and there is an increase in the cleaning area due to the terminal portion. When the dirt that was wiped off once is stretched and reattached from the cleaning cloth to the terminal part
In addition, due to the enlargement of such a cleaning area, the degree of soiling of the cleaning cloth becomes larger even in one cleaning operation, so the problem of the re-adhesion of the above-mentioned stains becomes significant.
In such a case, there is a problem that the quality improvement in the mounting process of the liquid crystal panel is hindered.

[0060] figure 1 A schematic perspective view showing a main configuration of a terminal cleaning device 101 as an example of the substrate terminal cleaning device according to the first embodiment of the present invention. The terminal cleaning device 101 according to the first embodiment is made by contacting a cleaning cloth as an example of a cleaning member with an edge or the like on the surface of a substrate for a flat display panel such as a liquid crystal display device (liquid crystal panel) or a plasma display panel (PDP). A device for cleaning by contacting and wiping the terminal part (or the surface of the terminal part or the area where the terminal part is arranged) formed at the terminal. In addition, in this specification, the so-called "cleaning" refers to removing stains adhering to the object by washing or sweeping, including, for example, wet cleaning using a cleaning cloth soaked in an organic solvent or the like, or cleaning without using a solvent.

[0114] In addition, this invention is not limited to the said embodiment, It can implement in other various forms. E.g, Figure 10 It is a schematic explanatory diagram showing a partial structure of the cleaning unit 110 included in the terminal cleaning device according to the second embodiment of the present invention.

[0115] like Figure 10 As shown, in the cleaning unit 110, there is a twisting mechanism 120 that reverses the surface and the back of the cleaning cloth 2, so that the contact surface of the cleaning cloth 2 that uses the first cleaning head 111 to contact the terminal portion 6 of the substrate 5 It has a structure different from that of the cleaning unit 10 of the first embodiment in that the contact surface of the cleaning cloth 2 contacting the terminal part 6 by the second cleaning head 112 is reversed from the front to the back.

[0116] Specifically, as Figure 10 As shown, the constituent parts of the cleaning unit 110 on the upper side have: four...

Abstract

A substrate terminal cleaning apparatus which performs cleaning of a terminal section of a substrate by having a cleaning member abut to the terminal section. The substrate terminal cleaning apparatus is provided with a first supporting section for supporting the cleaning member at a first position; a second supporting section for supporting the cleaning member at a second position; a cleaning head section for applying pressure to a part of the cleaning member, which is being supported between the first position and the second position, by having the part of the cleaning member abut to the terminal section of the substrate; a supporting section moving apparatus for integrally moving the first supporting section and the second supporting section in a direction along the terminal section; and a cleaning head moving apparatus for moving the cleaning head section in the direction along the terminal section, at a second moving speed different from a first moving speed at which the supporting section moving apparatus moves the first supporting section and the second supporting section.

Description

technical field [0001] The present invention relates to a substrate terminal cleaning device for cleaning a terminal portion on a substrate, and more particularly to a liquid crystal panel mounting terminal surface for improving the mounting quality of ICs and the like mounted on the mounting terminal surface of a liquid crystal panel serving as the substrate. A cleaned liquid crystal panel terminal cleaning device and a substrate terminal cleaning method. Background technique [0002] In recent years, the demand for liquid crystal panels has increased rapidly, and there is a strong desire to improve the quality and yield of liquid crystal panels. Among them, in order to improve the quality and yield in the liquid crystal panel mounting process, it is effective to clean (clean or sweep) the mounting surface again before the mounting process, and interest in liquid crystal panel terminal cleaning devices has increased. [0003] Here, the structure (for example, refer patent ...
