Description
Technical Field
The utility model relates to a laser cutting processing field especially relates to a cutting lobe of a leaf system of laser precision finishing glass.
Background
The laser cutting glass has the obvious advantages of high processing speed, high precision, simple parameter setting and the like, and becomes a choice for large-batch processing. Since the laser is a non-contact tool, there are no wear problems, thus ensuring a continuous, uniform cut thickness and edge quality. Authoritative measurements showed that the average roughness (Ra) was less than 0.5 μm. Because of the excellent edge quality and natural tempering effect, the laser cut edge strength is very high, which is improved by about 30% compared to a sample that is ground after machining. Laser cutting avoids side cracks, not only is the impact strength of the edge enhanced, but the strength of the whole assembly can be generally improved by 80%, thereby obviously improving the damage resistance of the part. The increased strength of the material reduces the likelihood of damage and loss, as well as reducing the problem of premature field failure due to potential product defects. This is a great advantage for product design, where the designer can not only use lighter, thinner materials, but also does not affect the product lifetime.
In the microelectronics industry, the precision and efficiency of optical glass manufacturing and processing are also continuously improved. The problem that laser cutting processing exists at present is that because the kerf between a small-size glass plate and a large-size optical glass body after laser cutting is only about five microns, the acting force between sheets is large, the sheets cannot fall off freely, and the sheets can be separated by a certain external force. Therefore, the chinese patent application No. 201810992630.X provides a splitting process for laser optical glass cutting, but the splitting step is relatively complicated.
When the intensity of the laser pulse is higher than the damage threshold of the transparent glass material, the laser Filamentation generates a high aspect ratio damage channel with the order of tens of microns in the glass, and a specific fracture geometric track in the glass material can be realized by controlling the relative position of a light beam and a sample, finally the final sample cutting is realized by the way that a cutting part falls off from the substrate or cracks are assisted, the novelty of the laser Filamentation cutting attracts the great attention of the market, and the advantages of high cutting speed, little chip generation and high sample edge intensity are obvious, however, the sample which is difficult to cut by the laser Filamentation cutting often has the phenomenon of successfully separating from the substrate, and the external force needs to be applied to separate,
the stripping force after laser filamentation cutting is generally cracked by using a CO2 laser along a cutting path (cutting track) auxiliary heating mode, and a carbon dioxide laser has a complex structure and huge maintenance cost, so that not only is the front mirror and the tail mirror expensive, but also the service life of a turbine bearing is only 8000 hours, and the replacement cost reaches 8 ten thousand yuan per pair. In addition, the carbon dioxide laser cutting machine not only generates gas consumption during processing, but also has the photoelectric conversion rate of only 8-10%. Secondly, the carbon dioxide laser has a large beam divergence and is not suitable for large-scale processing.
The Chinese patent application CN201711393518 optimizes the path of carbon dioxide laser cutting splinters, and is hopeful to avoid the cracking of products to be cut caused by cutting and improve the yield of finished products.
