Description

Method, controller and apparatus for substrate glass processing

Technical Field

The present disclosure relates to the field of semi-finished product processing technology for substrate glass, and in particular, to a method, controller and apparatus for substrate glass processing.

Background

The current production modes of substrate glass (e.g., liquid crystal substrate glass) production lines are as follows: and after one transverse cutting and one longitudinal cutting, the semi-finished product area is judged by a semi-finished product inspection room, and if the semi-finished product area is not defective, packaging and defects are directly discarded. This results in many substrate glasses being discarded due to defects in either the top or bottom half. However, the high-order substrate glass can be divided into a plurality of low-order substrate glasses, for example, the G6 substrate glass can be divided into four G4.5 substrate glasses, and the G8.5 substrate glass can be divided into four G5 substrate glasses. In this sense, because of the local defect, the existing production line directly discards a large amount of high-generation substrate glass, so that not only the production capacity of the production line cannot be exerted to the maximum, but also a large amount of resources are wasted, and along with the gradual increase of the generation times of the substrate glass, the production mode aggravates and worsens the capacity loss of the production line.

Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

In the present disclosure, the use of directional terms such as "up" and "down" generally means up and down when the apparatus is actually used, unless otherwise specified.

Fig. 1 is a flow diagram illustrating a method for substrate glass processing according to an exemplary embodiment, which may include the following steps, as shown in fig. 1.

In step 101, it is determined whether the substrate glass has a defect.

In step 102, when the substrate glass has a defect, a cutting device is controlled to cut the substrate glass.

Through the technical scheme, when the substrate glass is judged to have defects, the cutting device is controlled to cut the substrate glass. Therefore, the direct abandonment of the defective substrate glass can be effectively avoided, the defective substrate glass can be cut and then recycled, the abandonment of the substrate glass is reduced, the resource utilization rate is improved, and the qualification rate of products is improved.

Specific embodiments of the present disclosure are described in detail below.

The defect of the substrate glass may be a bubble, a stone, or the like, and may be detected by a detection device such as an edge light detector in step 101, and when the defect is detected, the cutting device needs to be controlled to cut the substrate glass in step 102. The cutting mode can be a fixed cutting mode, that is, the size of the glass substrate after cutting can be set in advance according to the size of the substrate glass, and the cutting position is fixed and unchanged. For example, one piece of G6 substrate glass (1500 mm. times.1850 mm) may be divided into four pieces of G4.5 substrate glass (730 mm. times.920 mm). For another example, one G8.5 substrate glass (2200mm × 2500mm) may be divided into four G5 substrate glasses (1100mm × 1250 mm). When a fixed cutting mode is adopted for cutting, the method is simple, complex calculation is not needed, and the cutting efficiency is high.

If the cutting is performed by the fixed cutting method in the above example, the fixed cutting method is meaningless for the glass substrate having defects in all the four corners, and only the glass substrate having defects in all the four corners can be discarded.

In an embodiment of the present disclosure, the cutting manner may also be adjusted according to the defect position. Fig. 2 is a flowchart illustrating a cutting step for a substrate glass processing method according to an exemplary embodiment, and the step of controlling the cutting device to cut the substrate glass (step 102) may include the following steps when the substrate glass has a defect, as shown in fig. 2.

In step 1021, when the substrate glass has a defect, the defect position of the substrate glass is determined.

In step 1022, a cutting position is determined based on the defective position of the substrate glass.

In step 1023, a cutting device is controlled to cut the substrate glass according to the cutting position of the substrate glass.

In the embodiment, a better cutting mode can be determined according to the defect position, so that the substrate glass can be utilized to a greater extent. For example, several sets of cutting methods may be predetermined, and a cutting method capable of making the size of the defect-free substrate glass obtained after cutting larger may be selected for cutting according to the defect position. Alternatively, a predetermined size is determined so that the defect-free substrate glass obtained after cutting is the predetermined size. When the latter cutting mode is adopted, the sizes of the cut substrate glass can be consistent, and the later packaging and arrangement are convenient. For example, if a defect exists at each of the four corners of a piece of G6 substrate glass and the predetermined size is the size of G4.5 substrate glass, a piece of G4.5 substrate glass without defects can be cut from the middle portion of the G6 substrate glass according to the defect position and reused.

Fig. 3 is a flowchart illustrating a cutting step for a substrate glass processing method according to another exemplary embodiment, and the step of determining a cutting position according to a defective position of the substrate glass (step 1022) may include step 10221 on the basis of fig. 2, as shown in fig. 3.

In step 10221, a cutting position is determined according to a defect position of the substrate glass, so that one or more defect-free portions are generated after the substrate glass is cut, and the size of at least one defect-free portion is one of a plurality of predetermined sizes.

Specifically, the size of the required substrate glass may be set to the above-described predetermined size (for example, the size of each generation substrate glass). For example, it was detected that a piece of G6 substrate glass had defects at all four corner positions, and one or two pieces of G4.5 substrate glass could be cut in the middle thereof. The cutting can be performed according to the principle that the area of the discarded substrate glass is the smallest, so that the substrate glass raw material can be utilized to a greater extent. For example, the sizes of the substrate glasses gradually increase from G3 to G10, and if the substrate glass to be cut is G6, the substrate glass of the generations below G6 (excluding G6) may be selected as a cut product according to the position of the defect, and the sizes of the substrate glass of the generations below G6 may be determined to the above-mentioned plurality of sizes. And calculating the areas of the waste substrate glass required by various cutting modes, thereby selecting the cutting mode.

After the predetermined size is determined (i.e., the generation of the cut substrate glass is determined), the substrate glass of a desired generation may be produced (detected to be defect-free) in the production line of the substrate glass, and the production line may additionally produce the substrate glass of a predetermined generation or generations (smaller than the generation required for the main production) because a part of the substrate glass is cut after being detected to be defective. Different cutting modes can be selected according to actual requirements, so that the economic benefit of cutting the substrate glass is maximized, and the waste is reduced.
