Abstract

A display module terminal cleansing device includes a wiper assembly and a gas blower assembly. The gas blower assembly is first operated to blow away particle foreign substances located on a terminal area to be cleansed And, then, the wiper assembly is operated to wipe off foreign substances remaining on the terminal area. The display module terminal cleansing device may achieve an effect of cleansing where water droplet angle on the surface of the cleansed terminal area is less than 15° and also prevents a potential issue of scratching and damaging the display module during the process of cleansing. Also disclosed is a display module terminal cleansing method.

First claim

What is claimed is:

1 . A display module terminal cleansing device, which is adapted to cleanse a terminal area of a display module, wherein the display module terminal cleansing device comprises a gas blower assembly and a wiper assembly, the gas blower assembly being operable to conduct a gas blowing operation to blow particle foreign substances away from the terminal area of the display module, the wiper assembly being operable to remove foreign substances remaining on the terminal area after the gas blowing operation conducted by the gas blower assembly,
wherein the wiper assembly comprises at least one wipe head having an end that is wrapped by a piece of wipe cloth to define a flat wiping surface, the gas blower assembly comprising a gas supply channel that is combined with the wiper assembly and is arranged in an interior of the wipe head.

2 . The display module terminal cleansing device as claimed in claim 1 , wherein the wiper assembly is operable in combination with a cleansing solvent to remove the foreign substances remaining on the terminal area.

3 . The display module terminal cleansing device as claimed in claim 2 , wherein the foreign substances remaining on the terminal area include organic foreign substances, and the cleansing solvent is selected as one of alcohol, propyl alcohol, and isopropyl alcohol according to the remaining foreign substances.

4 . The display module terminal cleansing device as claimed in claim 1 , wherein the at least one wipe head of the wiper assembly comprises two wipe heads each of which is wrapped by a piece of wipe cloth, a liquid supply channel being arranged in each of the wipe heads, the liquid supply channel being connected to a cleansing solvent supply section to supply cleansing solvent to the wipe cloth, the wipe heads being operable to drive the wipe cloth that is impregnated with the cleansing solvent to wipe off the foreign substances remaining on the terminal area.

5 . The display module terminal cleansing device as claimed in claim 4 , wherein the liquid supply channel is arranged to extend through the interior of each of the wipe heads, the liquid supply channel having an end connected to the cleansing solvent supply section and an opposite end extending through the flat wiping surface to directly supply the cleansing solvent to the wipe cloth that is wrapped around the flat wiping surface.

6 . The display module terminal cleansing device as claimed in claim 1 , wherein the gas blower assembly comprises a gas pump and the gas supply channel is connected to the gas pump, the gas supply channel being arranged to extend through the flat wiping surface to supply gas supplied from the gas pump to a portion of the terminal area that opposes the wipe head.

7 . The display module terminal cleansing device as claimed in claim 1 , wherein the gas blower assembly comprises a clean dry air module that supplies a high-pressure, dry, and clean airflow.

8 . The display module terminal cleansing device as claimed in claim 1 , wherein the gas blower assembly comprises a gas pump and the gas supply channel is connected to the gas pump, the gas pump being operable to supply a high-pressure, dry, and clean gas, the gas supply channel supplying the gas to the terminal area.

9 . The display module terminal cleansing device as claimed in claim 1 , wherein the terminal cleansing device further comprises an installation section and a support section, the installation section allowing the wiper assembly to be installed and fixed and driving the wiper assembly to move relative to the terminal area, the support section supporting a display module to be cleansed thereon and driving the display module to move relative to the wiper assembly and the gas blower assembly.

10 . The display module terminal cleansing device as claimed in claim 2 , wherein the terminal cleansing device further comprises an installation section and a support section, the installation section allowing the wiper assembly to be installed and fixed and driving the wiper assembly to move relative to the terminal area, the support section supporting a display module to be cleansed thereon and driving the display module to move relative to the wiper assembly and the gas blower assembly.

11 . The display module terminal cleansing device as claimed in claim 3 , wherein the terminal cleansing device further comprises an installation section and a support section, the installation section allowing the wiper assembly to be installed and fixed and driving the wiper assembly to move relative to the terminal area, the support section supporting a display module to be cleansed thereon and driving the display module to move relative to the wiper assembly and the gas blower assembly.

12 . The display module terminal cleansing device as claimed in claim 4 , wherein the terminal cleansing device further comprises an installation section and a support section, the installation section allowing the wiper assembly to be installed and fixed and driving the wiper assembly to move relative to the terminal area, the support section supporting a display module to be cleansed thereon and driving the display module to move relative to the wiper assembly and the gas blower assembly.

13 . The display module terminal cleansing device as claimed in claim 5 , wherein the terminal cleansing device further comprises an installation section and a support section, the installation section allowing the wiper assembly to be installed and fixed and driving the wiper assembly to move relative to the terminal area, the support section supporting a display module to be cleansed thereon and driving the display module to move relative to the wiper assembly and the gas blower assembly.

14 . The display module terminal cleansing device as claimed in claim 6 , wherein the terminal cleansing device further comprises an installation section and a support section, the installation section allowing the wiper assembly to be installed and fixed and driving the wiper assembly to move relative to the terminal area, the support section supporting a display module to be cleansed thereon and driving the display module to move relative to the wiper assembly and the gas blower assembly.

15 . The display module terminal cleansing device as claimed in claim 7 , wherein the terminal cleansing device further comprises an installation section and a support section, the installation section allowing the wiper assembly to be installed and fixed and driving the wiper assembly to move relative to the terminal area, the support section supporting a display module to be cleansed thereon and driving the display module to move relative to the wiper assembly and the gas blower assembly.

16 . The display module terminal cleansing device as claimed in claim 8 , wherein the terminal cleansing device further comprises an installation section and a support section, the installation section allowing the wiper assembly to be installed and fixed and driving the wiper assembly to move relative to the terminal area, the support section supporting a display module to be cleansed thereon and driving the display module to move relative to the wiper assembly and the gas blower assembly.

17 . The display module terminal cleansing device as claimed in claim 9 , wherein the terminal cleansing device further comprises an installation section and a support section, the installation section allowing the wiper assembly to be installed and fixed and driving the wiper assembly to move relative to the terminal area, the support section supporting a display module
