Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of glass substrate cleaning, in particular to a glass substrate cleaning device for vehicle-mounted display screens. BACKGROUND

[0002] The LED vehicle-mounted screen is installed on the vehicle, and is manufactured by using a special power supply, a control card and a unit board. The LED vehicle-mounted screen displays characters, pictures, animations and videos through dot matrix display. It is a set of LED vehicle-mounted display system which is separated from the rapid development of the LED display screen. Compared with the ordinary signboard screen and the fixed LED display screen, the LED vehicle-mounted screen has higher requirements for stability, anti-interference, shock resistance and dust prevention. The LED vehicle-mounted screen is usually a liquid crystal display screen, and the glass substrate is a thin glass sheet with extremely smooth surface, which is one of the key basic materials in the flat panel display industry. The glass substrate is mainly used to form a liquid crystal display device, and is produced by the float method, overflow down-draw method or slot down-draw method.

[0003] During the production of the glass substrate, glass particles are generated. If the glass particles are not completely removed and adhere to the surface of the glass substrate for a long time, the ordinary spray cleaning method cannot remove the glass particles, and the glass particles may damage the surface of the glass substrate in the subsequent process, thereby affecting the yield of the glass substrate.

[0004] Chinese patent publication No. CN115338156B includes a cleaning tank and two symmetrical bearing filter plates installed in the cleaning tank. The top of the bearing filter plate is matched with the glass substrate, and the right end of the bearing filter plate is matched with the lifting mechanism. The present application provides a glass substrate surface liquid cleaning mechanism. Through the setting of the cleaning tank, the glass substrate can be soaked in the cleaning tank first, then cleaned with a cleaning brush, and then dried with a cleaning air knife. After drying, the glass substrate is adsorbed and lifted by a vacuum chuck mechanism. The cleaning brush is adjusted to turn and clean the lower surface of the glass substrate. After cleaning, the glass substrate is washed through the cleaning tank and moved to the next cleaning process. Through this setting, the glass particles on the surface of the glass substrate can be effectively removed to ensure the yield of the glass substrate.

[0005] The applicant finds that the patent has some deficiencies in use: when the glass substrate is washed, the cleaning brush first washes the front surface of the glass substrate, then lifts the glass substrate, adsorbs the front surface of the glass substrate by the suction cup, and then washes the back surface of the glass substrate by the cleaning brush. Through the way of washing one by one, the efficiency is not high enough.
