Problems solved by technology

In the existing detection of the edge of the liquid crystal glass substrate, since the glass runs in one direction, when detecting the 4 sides of the glass, it needs 4 times of detection to complete. Both sides of the conveyor belt in the forward direction), the glass needs to be stationary, and the detection equipment moves to complete the detection, which has a great impact on the beat of the entire production line and seriously affects the operating efficiency of the production line

[0039] The first detector 1 and the second detector 2 are symmetrically fixed on both sides of the glass substrate, respectively located at the end points of the same side of the first side 11 and the second side 12 of the glass substrate to be tested, and the glass substrate to be tested With the movement of the conveyor belt, under the condition that the glass substrate is moving and the first detector 1 and the second detector 2 are stationary, when the neutral borosilicate glass substra...

Embodiment 2

[0045] In this embodiment, there are three glass substrates to be tested. The glass substrate edge detection system of this embodiment can intermittently detect two glass substrates at the same time.

[0046] The liquid crystal glass substrate described in this embodiment is soda glass, rectangular in shape, the length of the first side and the second side is 1850mm, and the length of the third side and the fourth side is 1500mm. The edge inspection system for glass substrates detects two glass substrates at the same time, such as figure 2 shown.

[0047] The glass substrate 5, the glass substrate 6 and the glass substrate 7 move along the preset direction with the conveyor belt, the first detector 1 and the second detector 2 are fixedly arranged, and the third detector 3 and the fourth detector 4 are located in two adjacent blocks to be Measure between the glass and move under the drive of the driver.

[0048] When the first side and the second side of the glass substrate...

Embodiment 3

[0056] In this embodiment, there are three glass substrates to be tested. The glass substrate edge detection system of this embodiment can continuously detect two glass substrates at the same time.

[0057] The liquid crystal glass substrate described in this embodiment is soda glass, rectangular in shape, the length of the first side and the second side is 1850mm, and the length of the third side and the fourth side is 1500mm. The edge inspection system for glass substrates detects two glass substrates at the same time, such as image 3 shown.

Abstract

The invention relates to a side detection system and method for a glass substrate. The glass substrate has a first side, a second side, a third side and a fourth side. The first side is parallel to the second side. The detection system comprises a driving device, a first detector, a second detector, a third detector and a fourth detector. The driving device is a driver or two drivers, the first detector is fixed to the second detector, and the third detector and the fourth detector are driven by the driving device to move. The detection method includes the steps that the first detector and the second detector detect the first side and the second side of the glass substrate to be detected respectively, and the third detector and the fourth detector detect the third side and the fourth side of the glass substrate to be detected respectively. By means of the method, the side detection efficiency of the glass substrate can be improved, the production efficiency of a whole production line can be improved, errors generated in the detection process are reduced, and the service life of the detectors is prolonged.

Description

technical field [0001] The invention relates to an edge detection of a glass substrate, in particular to an edge detection system and a detection method of a glass substrate. Background technique [0002] In recent years, with the development of modern science and technology and the advancement of information technology, display technology is gradually developing in the direction of light weight and large format. Liquid Crystal Display (LCD for short) has the advantages of low operating voltage, no radiation, no flicker, space saving, etc., and has been widely used in high-end electronic display fields such as optoelectronics, biomedicine, and national defense, such as LCD TVs, instruments Instrumentation, communication, monitoring, etc. [0003] The liquid crystal display glass substrate is thin in thickness and large in area, and is an important part of the liquid crystal display panel. In order to improve work efficiency in production, usually a larger liquid crystal gl...
