Description
Technical field
The present invention relates to the light beam manipulation device of a kind of laser-beam drilling machine, especially for the laser-beam drilling machine on cork paper.
Background technology
At present, cork paper is mainly used in the making of cigarette filter, in order to reduce the tar content of medicated cigarette, reduces Buddhist nun
The Gu Ding harm to health, the major measure taked is exactly to punch on cork paper, it is ensured that smoker sucks one when smoking
Fixed air, reduces the purpose of tar content.Now, the light beam manipulation device master of the laser-beam drilling machine commercially used
Having two kinds, one is to coordinate composition high speed rotating polygon prism with high-speed electric expreess locomotive with accurate polyhedral prism, and laser beam becomes high
Speed pulse laser, imports parallel optics successively and forms multipath pulse laser, and the light beam manipulation device of this structure is more complicated,
Very flexible, is suitable only under line punching；Another kind is directly to use high-frequency pulsed lasers device to make LASER Light Source, uses eyeglass to divide
The road light that laser instrument is sent by photosystem is directly divided into multi beam, and the light beam manipulation device of this structure is simple, uses flexibly, can
Online or punch under line, but the disadvantage that this device exists is that its light path is to realize opening or closing of light path by optical gate switch
Closing, if in the case of limiting laser power, and beam splitting system is constant, it is meant that if the merit of the main line light beam wherein closed
Rate will be lost, and the speed of laser boring is affected relatively, it also reduce the air permeability of the cork paper being perforated, and this is also
The problem that the application will solve just.
Summary of the invention
It is an object of the invention to provide and can adjust laser beam way as required, and a kind of laser that general power is not lost is beaten
The light beam manipulation device of hole machine.
The present invention adopts the technical scheme that: the light beam manipulation device of a kind of laser-beam drilling machine, and it is by high-speed pulse laser
Device, reflecting mirror one, laser alignment mirror, reflector, beam splitter and integrated focusing device composition, laser alignment mirror is convex by one
Lens and a concavees lens composition, reflector includes a reflecting mirror two and a printing opacity source window one, and beam splitter includes several
Spectroscope and a printing opacity source window four, integrated focusing device includes some reflecting mirrors three and some focus lamps；High-speed pulse swashs
Light device sends output beam, is successively transmitted in the concavees lens in laser alignment mirror and convex lens, from reflector by reflecting mirror one
Printing opacity source window one enter, by the spectroscope light splitting in beam splitter to printing opacity source window four, then by integrated focusing device
Send after reflecting mirror three to focus lamp；It is characterized in that beam splitter can move up and down, and be respectively symmetrically on reflector and beam splitter
And equal several printing opacity source windows two and printing opacity source window three, printing opacity source window two and the printing opacity source window three of being provided with of spacing can open
Or Guan Bi.
Use the present invention, when needs reduce light beam, can move on beam splitter, simultaneously nethermost by reflector
On printing opacity source window two and beam splitter, the printing opacity source window three of topmost is closed, it is possible to reduce light beam, corresponding spectroscope
Light splitting degree reduce, but the light extraction efficiency of light beam is constant, and namely power keeps constant, arranges after beam splitter with original
Optical gate, it just switches off light and still has light beam to compare, and can effectively improve work efficiency.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the present invention.
In figure, sequence number represents；High speed pulsed laser 1, reflecting mirror 1, concavees lens 3, laser alignment mirror 4, convex lens
5, printing opacity source window 1, reflecting mirror 27, reflector 8, printing opacity source window 29, printing opacity source window 3 10, spectroscope
11, printing opacity source window 4 12, beam splitter 13, reflecting mirror 3 14, integrated focusing device 15 and focus lamp 16.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail.
With reference to Fig. 1, the light beam manipulation device of this laser-beam drilling machine sends four road light beams, and it is by high speed pulsed laser 1, anti-
Penetrate mirror 1, laser alignment mirror 4, reflector 8, beam splitter 13 and integrated focusing device 15 to form, laser alignment mirror 4
Being made up of a convex lens 5 and concavees lens 3, reflector 8 includes a reflecting mirror 27 and a printing opacity source window one
6, beam splitter 13 includes three spectroscopes 11 (quantity determines) and a printing opacity source window 4 12 according to the light beam number sent,
It is separately 1/4,1/3 and 1/2 that spectroscopical light splitting divides from top to bottom, and integrated focusing device 15 includes four reflecting mirrors 3 14
(quantity determines according to the light beam number sent) and four focus lamps 16 (quantity determines according to the light beam number sent)；Beam splitter 13
Can move up and down, and be respectively symmetrically on reflector 8 and beam splitter 13 and spacing is equal is provided with three printing opacity source window 29 Hes
Three printing opacity source windows 3 10, printing opacity source window 29 and printing opacity source window 10 3 can closure or openness.
Under normal circumstances, when high speed pulsed laser 1 sends output beam, successively it is transmitted in laser by reflecting mirror 1
Concavees lens 3 in collimating mirror and convex lens 5, the printing opacity source window 1 from reflector 8 enters, by beam splitter 13
Spectroscope 11 light splitting is to printing opacity source window 4 12, then by reflecting mirror 3 14 to the focus lamp 16 in integrated focusing device 15
After send.
If needing to reduce by a road light beam, on beam splitter 13, can will move lattice, simultaneously nethermost by reflector 8
On printing opacity source window 29 and beam splitter 13, the printing opacity source window 3 10 of topmost is closed, this way it is ensured that external light source is not
Can enter, and light beam is radiated at the spectroscope 11 of 1/3 after entering beam splitter 13, the most just can reduce light beam, separate three tunnels
Light beam.If using the laser-beam drilling machine of 100 watts of power, by above-mentioned design, the power often restrainted is at 100/3 watt, therefore, always
The light extraction efficiency of light beam constant, namely power keeps constant.And the original way that optical gate is set after beam splitter 13,
Its light beam is still radiated on the spectroscope of 1/4 after entering beam splitter 13, still separates four kinds of light beams, if needing three road light beams,
The way used is to just switch off light later and Reng You tetra-road light beam, and the power of every road light beam is at 25 watts, and general power is 75
Watt, it is substantially reduced compared with original 100 watts, is lost bigger.
According to above-mentioned, if needing to reduce by two road light beams, it is only necessary to by moving lattice on beam splitter 13, simultaneously by reflector 8
On nethermost two printing opacity source windows 29 and beam splitter 13 on two printing opacity source windows 3 10 of topmost close
Realize.
It addition, for two tunnels, three tunnels, five tunnels and the design of above light beam number, be referred to above-mentioned four tunnels, with this type of
Push away.
