Description
Technical field
The present invention relates to a kind of dust-extraction units of laser equipment, more particularly to a kind of dust-extraction unit of etching laser machining
Component.
Background technology
At present during laser processing, the substance of machined material is by by after laser high-temp combustion, will produce dirt
The flue dust substance such as angstrom particle and gas, these flue dust substances often contain a large amount of harmfulness ingredient, some material compositions are in oxygen
It will produce very strong penetrating odor after change, influence the physical and mental health of operating personnel.So needing to set on laser process equipment
Necessary ventilation and dust removal device is set, the effect of dust-extraction unit directly affects production environment and product processing quality.
The principle of ventilation and dust removal device is：In laser processing procedure, the flue dust for processing generation is basically formed in material
Around the lower section of notch, dry process mode is generally taken at present：By suction type negative pressure cavity class device, alignment is carrying out
The region of processing carries out dust suction processing, achievees the purpose that dedusting.
Especially in etching laser machining performs etching process, for example, the processing to showing touch screen class product, processing
Material is often the silver paste etc. of ito thin film, substrate of glass or PET base, in etching process, will produce certain dust；This
It if a little dust cannot be eliminated from product rapidly, can remain on conductive film or silver paste circuit, influence product processing
Precision and quality.So requirement of the etching laser machining to dust-extraction unit can higher.
For at present, the dust-extraction unit of etching laser machining is generally all mounted below laser scanning head, structure be mostly one to
Semi-enclosed getter device of under shed makes the flue dust substance that processing generates in vacuum pressure by accessing vacuum breathing apparatus
Enough suction under take machining area out of.
Since conductive film or silver paste circuit etc. are that metal tunic etches the dust of generation during etching
Positive and negative charge can be carried, the surface of conductive film or silver paste circuit is readily adsorbed in, dedusting is caused to be not easy；In order to neutralize dust
Charge is additionally provided with ion wind stick in dust-extraction unit, using producible a large amount of air mass for carrying positive and negative charge on ion wind stick,
Neutral equilibrium can will be carried out by the charge of the dust in ionizing radiation area so that dust is easier to be siphoned away by suction.
Dust-extraction unit technology in the prior art takes above-mentioned structure setting, but dust removing effects can still cannot be satisfied
The quality requirement of the product of actual production process.Analyze the influence factor of dust removing effects：The principle of dedusting is to pass through dust-extraction unit
Cavity, dedusting under the premise of vacuum degree generates enough suction negative pressure, the air duct shape of inside cavity, caliber structure setting is straight
Connect the dispersion route for affecting flue dust；Simultaneously inlet scoop position setting and the distance apart from machining area be also directly affect because
Element.
A kind of dust-extraction unit of etching laser machining of the patent No. 201621065369.1, providing one kind can be by dust-extraction unit
Windshield move up and down, to meet the needs of under two kinds of different work states of loading and unloading and processing, and ensure windshield
The machining area generated with dust is maintained in suitable distance range, increases the effect of dedusting.This prior art is only from upper and lower
The factor part of distance solves the bad prior art problem of dedusting, can not provide better dust removing effects.It can from text
To find out, in prior art, since there are unreasonable hierarchic structures between dust excluding hood and wind shield, and vacuum noz(zle) is arranged
Directly it is exactly the size of caliber with dust excluding hood inner cavity junction in the upper end of dust excluding hood, part dust can be caused to be returned at ladder
Rotation, and cause to hinder in caliber junction, the effect of part suction is consumed, dust removing effects are influenced.
