Embodiment 1

[0042] In the present invention, the grinding residue cleaning treatment is performed on the glass substrate by the following method:

[0043] (1) After the glass substrate 2 is installed on the carrier substrate 1, the carrier substrate 1 rotates, and when the distances between the two calibration sensors 11 and the carrier substrate 1 detected at the same time are the distances of the bump points [preset in the control system] The distance detected by the calibration sensor 11 when the calibration sensor 11 is facing the guide protrusion 3], the control system determines that the current carrier substrate 1 is in the "positive position" state.

[0044] (2) The displacement drive mechanism 4 drives the ultrasonic sensor 16 on the second edge plate 15 to move downward at a constant speed, and the ultrasonic sensor 16 gradually scans the grinding surface of the glass substrate 2, and transmits the detected information to the control system.

[0045] (iii) After the ultrasonic i...

Embodiment 2

[0050] see figure 1 As shown, the carrier substrate 1 in the figure can be placed vertically. When the glass substrate 2 is subjected to high-pressure spray cleaning, the water flow and grinding residue can flow down quickly, and the displacement drive mechanism 4 can drive the displacement bracket 5 to move up and down at a constant speed. move, thereby driving the main mounting substrate 6 to move up and down.

[0051] see image 3 , Figure 5 , Image 6 As shown in the figure, there are two side mounts 12, a first side plate 13 and a second side plate 15 are installed between the two side mounts 12, and the narrower part in the middle of the side mount 12 is just right It is snapped at the position of the edge mounting groove 17 of the main mounting substrate 6 . The side mounting frame 12 is provided with side frame embedded mounting holes 19, the main mounting base plate 6 is provided with side mounting screw holes 18, and the bolts of the hexagonal socket are reinfor...

Embodiment 3

[0053] see figure 1 , figure 2 , Figure 4 As shown in the figure, the peripheral protective ring plate 10 encloses both the high-pressure spray nozzle 8 and the side air knife 9. When the high-pressure spray nozzle 8 sprays, the peripheral protective ring plate 10 can block the spray to avoid external The photoelectric sensor 14 and the ultrasonic sensor 16 have an influence.

[0054] The displacement driving mechanism 4 can drive the photoelectric sensor 14 on the first edge board 13 to move upward to the upper edge position of the glass substrate 2, and the displacement driving mechanism 4 can drive the ultrasonic sensor 16 on the second edge board 15 to move upward to the glass substrate 2. The position of the lower edge of the substrate 2 makes the sensing and detection of the glass substrate 2 by the ultrasonic sensor 16 and the photoelectric sensor 14 more comprehensive.

Abstract

The invention discloses a liquid crystal glass substrate grinding residue cleaning device and method, and relates to the technical field of liquid crystal glass processing. In the present invention, the output of the displacement driving mechanism is connected with a displacement bracket, and one end of the displacement bracket is installed with a main installation substrate. The lower side of the main installation base plate is embedded with side air knives located on both sides of the spray mechanism, and the lower side of the main installation base plate is fixedly installed with a peripheral protection ring plate located around the spray mechanism and the side air knives. A first edge board located on one side of the main installation substrate and a second edge board located on the other side of the main installation board are installed between the two edge mounts, and a number of optoelectronic devices are embedded in the lower side of the first edge board. Sensors, a plurality of ultrasonic sensors are embedded and installed on the lower side of the second edge plate. The invention adopts the cleaning device and drive control integrated with high-pressure spray washing, air-knife air-drying and clean detection, and has a high degree of automation, less process equipment to be switched, less water consumption, and less water required for subsequent treatment.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal glass processing, and in particular relates to a device and method for cleaning the grinding residue of a liquid crystal glass substrate. Background technique [0002] In the thinning process of the liquid crystal glass substrate, a large amount of grinding liquid and grinding powder will remain on the grinding surface of the liquid crystal glass after grinding. [0003] In the existing automatic cleaning methods, the glass surface is generally washed directly, which is not targeted, and it is easy to miss some areas that are not cleaned, and the large amount of washing water generated needs to be recycled or treated before being discharged (grinding powder CeO 2 Toxic, the flushing liquid needs to be filtered and treated), and the utilization rate of water resources is low. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a liquid crystal glass substr...
