Description

Focus positioner based on laser broken wall plant spore light energy acceptor

Technical Field

The utility model belongs to the technical field of the laser broken wall, concretely relates to focus positioner based on laser broken wall plant spore light energy acceptor.

Background

At present, the method for extracting the substances contained in spores by directly breaking the walls of medicinal plant spores and pollen spores through the light energy of laser to perform activity is a novel biological technology.

The method for breaking the wall of the plant spore by using the light energy of the laser is to directly use the focused focal light energy (light spot) of the laser to burn the hard wall shell of the spore to break the hard wall shell and allow the content of the spore to escape. In order to prevent the biological activity of the substances contained in the spores from being carbonized at high temperature by the light energy, firstly, a suspension material consisting of the plant spores and pure water needs to be prepared, so that the contents in the suspension material can immediately enter the water at the moment of wall breaking. The characteristic that the liquid suspension is not sensitive to laser irradiation is utilized, so that the optical energy of the laser is prevented from carbonizing the activity of spore inclusions. Because water is a stable macromolecular structure, pure water does not adversely affect the biological activity of spore contents by oxidation.

The application of laser to break the wall of plant spores requires great attention to the safety of human bodies, and because the laser wavelength range emitted by various common lasers covers 266 nm-1064 nm, part of laser wavelength light has different degrees of damage to human bodies. Meanwhile, high-intensity visible light or near infrared light has great harm to human eyes, an unattended site is required to be adopted in the processing process of laser light emission by utilizing a laser wall breaking technology, and meanwhile, the stay time of an operator in a laser wall breaking workshop needs to be reduced as much as possible.

In the prior art, the final purpose of all various processes for breaking the wall of plant spores based on laser is to improve the wall-breaking efficiency and the wall-breaking rate of the spores. The improvement of the wall breaking efficiency and the wall breaking rate of the spores can not only reduce the investment of production line equipment, but also reduce the time for the spores to receive laser irradiation, thereby reducing the damage degree of the nutrient contents of the spores caused by the laser irradiation to be carbonized to the minimum.

At present, the technology of 'water curtain method' and 'stirring method' is adopted in the industry for breaking the wall of plant spores by using laser more popular.

The description of the water curtain method process is as follows: the material is prepared by plant spore and pure water, carry the material to each light energy receiving area station on the production line through totally enclosed pipeline, every station comprises N lasers and the light energy acceptor of supporting quantity with it, there is the hollow target area of making by transparent glass in the structure of light energy acceptor, the target area warp the material that passes through into the water curtain wall form of thin flat type, the focus (facula) of laser carries out the rectangle region scan of setting for to the material water curtain wall in the target area, this set for region has formed a hexahedron of receiving the light energy with the rayleigh effect of facula in fact, carry out the energy conversion of light energy into heat energy in this hexahedron and exchange, the conversion medium is exactly the plant spore, the light energy of laser follows the law of conservation of energy and makes the spore in the water curtain wall type material burn the broken wall.

Whether the 'water curtain method' or the 'stirring method' is adopted to carry out the wall breaking of the plant spores, the adjustment of the laser focal length is a very important link, and the focal length is adjusted to position the laser focus at the specified position required by the adopted wall breaking process. According to the rayleigh effect, the interval of 10% attenuation of the peak power of a focus (light spot) of a general laser is about 1mm, namely the thickness interval of about +/-0.5 mm with the light spot as the center, and spores can receive the most appropriate laser wall breaking energy to break the wall after entering the interval. At present, a method of measuring a focal length by using a mechanical ruler is basically adopted in the industry, so that the stay time of an operator in a laser wall breaking workshop is too long, and potential safety hazards are caused.
