Problems solved by technology

[0002] Large-format glass processing methods mainly include water jet cutting and glass knife slicing; using water jet cutting to process large-format glass can cut large-format glass into products with various graphics, but due to water jet cutting large-format glass Restricted by the cutting line width of the water jet, it is impossible to process finer patterns; the cutting speed is fast and the processing efficiency is high when the glass knife is used to process large-format glass, but limited by the working method, it is mainly used for linear cutting of glass. Some large-format glass processing methods cannot meet the needs of higher requirements for large-format glass processing; therefore, this application proposes a method of using an ultra-fast picosecond laser cutting machine for large-format glass

Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0019] Such as Figure 1-2 As shown, a method for using a large-format glass ultra-fast picosecond laser cutting machine proposed by the present invention includes the following specific steps:

[0020] S1. The drive assembly 103 drives the glass to be cut 102 to move towards the emitting end of the laser 101;

[0021] Further, the drive assembly 103 is a linear motor device; the arrow in the figure refers to the direct...

Abstract

The invention discloses a use method of a large-format glass ultrafast picosecond laser cutting machine. The use method comprises the following specific steps that S1, a driving assembly drives glassto be cut to move towards the transmitting end of a laser; S2, the laser is electrified to run in the glass to be cut to generate a plurality of wire holes; the plurality of wire holes form microcracks on the glass to be cut, wherein the pulse width of the laser is not greater than 10ps; S3, external force is applied to the two sides of the microcracks on the the glass to be cut, so that the glass to be cut is cut off along the microcracks. After a glass workpiece is cut by the laser cutting machine, the cutting end face of the obtained glass workpiece is flat, secondary CNC grinding is not needed, and the machining efficiency is greatly improved; in addition, no sewage is generated in the glass workpiece machining process, the glass cutting machine is more environmentally friendly, the cutting speed is high, and the production efficiency of glass products is greatly improved.
