Description

Technical Field

[0001] The invention relates to the technical field of glassware processing, in particular to a material unloading device of a picosecond laser cracking machine. Background Art

[0002] Glass is an indispensable vessel in daily life. In the manufacturing process of glass, after the glass raw materials are blown and formed, there is often excess material left on the edge of the finished cup mouth that needs to be removed. This removal process is called "burst". The traditional method is to use a high-temperature flame to locally heat the product, so that the local temperature reaches a state of melting and flow, and then cut it with a diamond blade. At present, the burst is mainly completed by manual operation. However, due to the cutting of glass stone and uneven heating, there are large errors in manual operation, high scrap rate, low work efficiency, high energy consumption, low product grade, low quality, and easy to have high and low cups, bumping mouth, drawing and other quality problems, affecting the appearance of the product. Chinese patent CN201610066000 provides a fully automatic glass bursting machine. Although it can realize the automatic and continuous bursting of glassware. However, it still adopts the traditional heating bursting method, which is easy to cause the entire glassware to burst.

[0003] At present, there are also laser blasting machines that use laser beams as cutting tools. The laser beams are focused through optical elements such as lenses or reflectors to achieve high energy density, thereby achieving the cutting of the risers of glass cups. Afterwards, the edges of the cuts are ground, chamfered, cleaned and polished to further process the glass products. For example, a laser blasting machine (CN114105449A) and a laser blasting machine (CN108483893A) used in the production of high-heeled glasses are disclosed in Chinese patents.

[0004] It can be seen that the principle of the existing laser blasting machine is to shine a focused laser beam on the workpiece, causing the irradiated area to heat up rapidly, melting or vaporizing the material, and at the same time the laser beam moves along the contour line to melt the material and achieve cutting; its disadvantages are: the incision is not flat enough, and the incision edge needs to be polished, chamfered, rinsed, dried, flame polished and other processes later, the process is complicated, the consumables are high, the production cost is high, the breakage rate is high, the mouth quality is average, and the production efficiency is low. In order to solve the above technical problems, the applicant has designed a material unloading device for a picosecond laser blasting machine, and the present application is for a material unloading device for the picosecond laser blasting machine.
