Thin material laser online perforating device

Abstract

The invention discloses a thin material laser online perforating device which comprises a high power continuous laser, an optical splitting mechanism, two vibrating mirror scanning focusing mechanisms, a feeding mechanism and laser perforating heads which are arranged above the feeding mechanism and are relative to the two vibrating mirror scanning focusing mechanisms one by one, wherein the optical splitting mechanism comprises a mechanical modulation light splitting disc which is driven by a high speed motor to rotate, the mechanical modulation light splitting disc can divide continuous laser beams output by the high power continuous laser into two ways of pulse laser output by making use of light passing parts and light reflection parts which are circumferentially arranged at intervalsin an alternating way on the mechanical modulation light splitting disc, and the two ways of pulse laser output are respectively input into the two vibrating mirror scanning focusing mechanisms. By making use of the optical splitting mechanism, the invention can carry out narrow surface dense perforation on thin materials by only adopting a single high power continuous laser, and has the advantages of high efficiency, simple structure, low cost, high laser energy utilization ratio and higher performance price ratio.

Description

technical field [0001] The invention relates to a thin material laser online drilling device. Background technique [0002] Thin materials are a basic form of industrial materials. Many thin materials need to be prepared with dense micropores, such as laser drilling of tipping paper in the cigarette industry, or rubber paste in the pharmaceutical industry, or artificial leather, packaging films, etc. Dense air hole preparation is also required. [0003] Take thin materials such as rubber ointment as an example. As one of the leading dosage forms of traditional Chinese medicine, it occupies an important position in the development of traditional Chinese medicine. However, due to poor air permeability, traditional rubber ointment will cause skin redness, itching, ulceration, etc. side effect. In order to solve this problem, in recent years, the advanced mechanical contact punching method has been adopted to punch some of the products produced to increase the air permeability...

Problems solved by technology

However, the disadvantages of the above-mentioned patented equipment at present are: although multiple small and medium power radio frequencies are used to excite CO 2 Lasers are drilled in parallel, but due to the low laser power, the efficiency is still insufficient when performing large-format intensive drilling. In addition, the overall investment and cost of the equipment are still not small, and the waste generated during the production process is easy to clog Its exhaust system and other shortcomings, so the device was not able to gain widespread promotion in the end
