no. 3 approach

[0114] First, refer to Figure 12 A quality control device for glass substrates will be described.

[0115] Figure 12 It is a schematic diagram which shows the quality control apparatus of the glass substrate which is 3rd Embodiment of this invention. exist Figure 12 in, right with image 3 The same reference numerals are attached to the same structures, and explanations thereof are omitted.

[0116] In the above-mentioned first embodiment, the marking device 14 is a device that irradiates laser light to a predetermined position of the glass substrate 10 to process the glass substrate 10 to draw a mark, such as image 3 As shown, it is composed of a laser oscillator 14a, a moving device 14b, a position detection sensor 14c, a control device 14d, and the like.

[0117] On the other hand, in this embodiment, the marking device 14A is a device that ejects ink to a predetermined position on the surface of the glass substrate 10 to print a mark, and includes an inkjet head 1...

Abstract

A quality control method for a glass member includes a marking step of putting, in a prescribed position on a glass member, a reference mark to be used as a reference point indetectingaposition of a defect of the glass member in a prescribed range from the prescribed position.

Description

technical field [0001] The invention relates to a quality management method and a quality management device of a glass part and a marked glass part. Background technique [0002] In recent years, display panels such as LCD (Liquid Crystal Display), OLED (Organic Light-Emitting Diode), plasma display panels, and Field Emission Display (FED: Field Emission Display) have been increasing in size and thickness. , the size and thickness of glass substrates for high-quality display panels are constantly increasing. Accordingly, it becomes difficult to manufacture a glass substrate without defects. [0003] On the other hand, Patent Document 1 describes a technique of applying a mark indicating quality information (defect information) or identification information to a predetermined position of a glass substrate. Quality information includes the number, size, depth, and location of defects. By providing the glass substrate and its quality information to subsequent processes (incl...
