Problems solved by technology

With this method, only one piece can be cut at a time, and the cutting efficiency is low; and when cutting special-shaped or curved surfaces, the cutter head of the glass knife 300' is inconvenient to rotate, and the bending angle is relatively large, so it cannot cut large and multiple bends well. corner product
And after this kind of cutting, the edge waste remains on the finished product, and it is easy to produce fragments and cracks in the process of breaking the pieces to remove the edge waste
Moreover, thin flat glass itself is a fragile product. Using traditional cutting methods, the efficiency and yield rate of mass production are low

Embodiment Construction

[0016] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0017] The present invention provides a method for cutting thin plate glass, where thin plate glass generally refers to glass with a thickness of 0.33 mm to 1.5 mm. The cutting method includes the following steps: firstly, a plurality of sheets of flat glass are laminated and bonded together; then, the bonded sheet glass is fixed and cut by a water-sand mixed jet. The water-sand jet has a strong cutting force, and there is no need to break the pieces after the cutting is completed, which reduces man-made operation losses and improves the yield rate. The present invention also provides a thin...

Abstract

The invention relates to the field of cutting technology, and provides a cutting method and a cutting machine of sheet glass. The method comprises the following steps of: overlapping and bonding multiple pieces of sheet glass together; fixing the bonded sheet glass; and cutting with water-sand mixed jet flow. The cutting machine comprises a fixture platform, a water supply device, a sand supply device, a water-sand jet device, a transmission device and a controller, wherein the fixture platform is used for placing the sheet glass; the water-sand jet device is connected with the water supply device and the sand supply device and can eject the mixture of water and sand onto the sheet glass for cutting; the transmission device drives the water-sand jet device to move horizontally; and the controller is connected with the water-sand jet device and the transmission device. In the invention, multiple pieces of sheet glass are overlapped and bonded together and cut at a time, and thus the production efficiency is greatly improved; and moreover, the cutting force of water-sand jet flow is strong, the separation is not needed after the cutting, artificial operation loss is reduced, and the yield is increased.

Description

Technical field [0001] The present invention relates to the technical field of cutting, and more specifically, to a cutting method and a cutting machine for thin flat glass (0.33mm to 1.5mm) in a liquid crystal display device. Background technique [0002] At present, in the liquid crystal display industry, when cutting thin flat glass (0.33mm~1.5mm), glass knives such as diamond knives and diamond blades are generally used for cutting. The method is as figure 1 As shown, the thin plate glass 100' is placed on the cutting platform 200', and the glass cutter 300' is used for cutting. With this method, only one piece at a time can be cut, and the cutting efficiency is low; and when cutting special-shaped or curved surfaces, the cutting head of the glass cutter 300' is inconvenient to rotate, and the bend angle is large, and it cannot cut large bends and multiple bends well. Angular products. Moreover, after this cutting, the edge waste remains on the finished product, and fragmen...
