Embodiment Construction

[0025] Please check figure 1 , a cleaning device for a liquid crystal glass substrate, the glass substrate 10 has a first surface and a second surface opposite to each other, and the first surface is coated with an ITO film 20 . The cleaning device includes a frame 30 , a box body 40 attached to the frame 30 , an ultrasonic generator 50 , a delivery unit 60 attached to the frame 30 , and a liquid supply unit 70 for supplying cleaning liquid.

[0026] The frame 30 includes a collection tank, the collection tank has two long side walls 31, two short side walls and a lower wall, and the two long side walls 13, two short side walls and the lower wall are fixedly connected to form the above-mentioned collection with the opening facing upward. groove. If required, a cover plate can be provided to cover the opening of the receiving sump.

[0027] The box body 40 has a bottom wall and a peripheral wall extending upward from the peripheral edge of the bottom wall, and an opening is f...

Abstract

The invention discloses a cleaning device for a liquid crystal glass substrate. The first surface of the glass substrate is coated with an ITO (Indium Tin Oxide) membrane in a sticking manner; the cleaning device comprises a machine frame, a box body mounted on the machine frame in a connecting manner, an ultrasonic generator and a conveying unit mounted on the machine frame in a connecting manner, the ultrasonic generator is mounted below the box body in a connecting manner, the conveying unit is positioned below the ultrasonic generator and used for conveying the glass substrate, the second surface of the glass substrate faces downwards and is arranged on the conveying unit in a supporting manner, and the ITO membrane of the glass substrate faces upwards; a liquid supplying unit for supplying a cleaning solution is additionally arranged, the liquid supplying unit is used for adding the cleaning solution into the box body and enabling the cleaning solution to overflow from the box body, the overflowing cleaning solution flows onto the ITO membrane of the glass substrate, the ultrasonic generator sends out ultrasonic wave, and the cleaning to the ITO membrane is performed through the cleaning solution on the ITO membrane. The cleaning device has the advantages as follows: the ITO membrane can be protected, ultrasonic waves face the ITO membrane directly, the cleaning effect is good, the structure is simple, the cost is low, automatic production is achieved, and the labor cost is reduced.

Description

technical field [0001] The invention relates to a cleaning device for a liquid crystal glass substrate. Background technique [0002] The glass substrate has a first surface and a second surface opposite to each other, and the first surface is pasted with an ITO film by printing. After printing the ITO film, it must be cleaned. Otherwise, circuit breakage will occur due to insufficient cleanliness, which will increase the defect rate of the product, cause the loss of materials such as photosynthetic glue, and increase the cost sharply. The existing liquid crystal glass substrate cleaning equipment includes a cleaning tank, an ultrasonic generator attached to the bottom of the cleaning tank and a delivery unit attached to the cleaning tank. The ultrasonic generator is located under the delivery unit, and the cleaning tank has cleaning liquid. In order to protect the ITO film and prevent the ITO film from being scratched, when the glass substrate is placed in the cleaning ta...
