Edge foreign matter processing system suitable for RTC laser cutting machine

Abstract

The invention discloses an edge foreign matter processing system suitable for an RTC laser cutting machine. The edge foreign matter processing system comprises the RTC laser cutting machine, a foreignmatter collecting mechanism and a foreign matter treatment mechanism. The foreign matter collecting mechanism is arranged at the cutting position of a laser cutting head, and the foreign matter treatment mechanism is connected with the foreign matter collecting mechanism through a collecting pipe. The foreign matter collecting mechanism comprises an upper collecting device and a lower collectingdevice which are used for collecting foreign matter generated in the cutting process, and the foreign matter treatment mechanism comprises a smoke exhaust chimney and a purification treatment device arranged in the smoke exhaust chimney. Edge foreign matter generated in the laser cutting process is treated through the foreign matter collecting mechanism and the foreign matter treatment mechanism,after the edge foreign matter is sucked through the upper collecting device and the lower collecting device, the cleanliness of the end face of a polarizing plate is improved, and meanwhile the quality of the polarizing plate is improved. Meanwhile, the air carrying the edge foreign matter is exhausted after being purified by the foreign matter treatment mechanism, so that the cleanliness of the exhausted air is guaranteed, and the environment-friendly value is relatively high.

Description

technical field [0001] The invention relates to an edge foreign matter processing system, in particular to an edge foreign matter processing system suitable for an RTC laser cutting machine, and belongs to the technical field of semiconductor laser cutting. Background technique [0002] Laser cutting is to irradiate the laser beam to the surface of the workpiece to release energy to melt and evaporate the workpiece, so as to achieve the purpose of cutting and engraving. It has high precision, fast cutting, not limited to the limitation of cutting pattern, automatic typesetting saves materials, smooth incision, and low processing cost. low feature. Now, laser cutting machines are more and more maturely used in various industries. Using the laser beam emitted from the laser generator, through the optical path system, it is focused into a high-power density laser beam irradiation condition. The laser heat is absorbed by the workpiece material, and the workpiece The temperature...

Problems solved by technology

Now, laser cutting machines are more and more maturely used in various industries. Using the laser beam emitted from the laser generator, through the optical path system, it is focused into a high-power density laser beam irradiation condition. The laser heat is absorbed by the workpiece material, and the workpiece The temperature rises sharply. After reaching the boiling point, the material begins to vaporize and form holes. With the high-pressure airflow, as the relative position of the beam and the workpiece moves, the material finally forms a slit. During this process, a lot of smoke and dust will be generated. Dust residue will adhere to the surface of the workpiece, affecting the processing quality of the workpiece

[0003] At present, among the equipment in the industry, laser cutting is mostly used to expose the polarizer in an open space. The dust generated by cutting is not collected or only collected briefly, but there is still a large amount of residual smoke that has not been collected. In this Under normal circumstances, the smoke and dust diffuse freely to the surrounding, part of which is inhaled by the human body, affecting human health; part of it is absorbed by the polarizer, resulting in poor product quality

[0004] Due to the lack of collection of smoke and dust, or simple collection, there is a problem of poor collection effect, resulting in a large amount of residual smoke and dust that has not been collected during the cutting process, resulting in free diffusion of smoke and dust inside and outside the equipment, which in turn affects the operator Health and quality of cutting products
