Abstract
The invention provides a lens dust-proof device of a laser marking machine. The lens dust-proof device is used in the field of auxiliary equipment of the laser marking machine, and is mainly used for the laser marking machine equipment at places with dust or unclean environment. An annular dust blowing chamber is arranged at the front end of a lens of the laser marking machine or a blowing groove is arranged on a lens protective cover; an air inlet port is formed on an external wall; and a plurality of dust blowing small holes or blowing grooves are formed on a working surface of the annular dust blowing chamber that is arranged as a circle on an internal wall. A lens protective shade capable of being automatically opened and closed is arranged inside the annular dust blowing chamber. When the laser marking machine is turned off, the lens protective shade can be automatically closed; and the dust blowing small holes start to blow before marking of the laser marking machine, and the lens protective shade is automatically opened, so that the dust is prevented from entering the area close to the marking lens.
Description
Technical field
Be used for the auxiliary equipment of laser marking machine, be mainly used in flue dust, the uncleanly occasion of dust or environment is carried out the camera lens dust guard of laser marking machine equipment.
Background technology
Existing laser marking machine; Major part all is at environment facies the occasion of cleaning, rarer dust to be used; For the laser marking machine that uses under the relatively poor production environment of environment, because camera lens receives the pollution of dust or dust and influences the quality of mark and the effect of mark through regular meeting.The dustproof general mode of manual wipping that adopts of the camera lens of present laser marking machine is carried out, and this method may be brought damage to camera lens, also can influence production efficiency.
Summary of the invention
To above-mentioned condition, the present invention has mainly solved in the process of laser marking can carry out dustproof device and method for using automatically.Technical scheme of the present invention: the blowing groove of annular drifting dust cavity being installed or being covered at the camera lens front end of laser marking machine at lens protection; Said outer wall has an intake interface, several drifting dust aperture or blowing grooves on the working face of the annular drifting dust cavity of inwall one circle.Annular drifting dust cavity installed inside has the lens protection cover door of automatic folding.When laser marking machine shut down, lens protection cover door was closed automatically, and before laser marking machine carried out mark, the drifting dust aperture began to blow, and lens protection cover door is opened automatically again, makes dust can not get into mark camera lens near zone.

Embodiment
Dual mode:
Accompanying drawing one: when laser marking machine energising start; The energising of air blowing magnetic valve; The drifting dust aperture that is positioned at the annular drifting dust cavity
on the lens protective cover
begins to blow, and forms a protection air curtain in camera lens the place ahead; The energising of lens protection cover magnetic valve; The push rod of small-sized cylinder is opened protective cover door
, has effectively avoided the camera lens of flue dust near laser marking machine.After mark is accomplished; Lens protection cover magnetic valve with blow afloat magnetic valve and cut off the power supply simultaneously; The protective cover door
of lens protection cover
is closed earlier; Stop behind the residual gas in the compressed air emptying gas circuit in the drifting dust aperture of annular drifting dust cavity
blowing; The camera lens of laser marking machine is isolated from the outside comes, avoided dust and dust before the protective cover door is closed approaching.
Accompanying drawing two:
When laser marking machine energising start; The energising of air blowing magnetic valve; The drifting dust groove
that is positioned on the lens protective cover
begins to blow, and forms a protection air curtain in camera lens the place ahead; The energising of lens protection cover magnetic valve; The push rod of small-sized cylinder is opened protective cover door
, has effectively avoided the camera lens of flue dust near laser marking machine.After mark is accomplished; Lens protection cover magnetic valve with blow afloat magnetic valve and cut off the power supply simultaneously; The protective cover door
of lens protection cover
is closed earlier; Stop behind the residual gas in the compressed air emptying gas circuit of drifting dust groove
lining on the lens protective cover
blowing; The camera lens of laser marking machine is isolated from the outside comes, dust and dust when having avoided before the protective cover door is closed are approaching.
Claims (6)
1. the camera lens dust guard that is used for laser marking machine is mainly used in occasion that dust or environment not too clean and carries out the device that the camera lens of the machinery equipment of laser marking carries out proofing dust and protecting; It is characterized in that: when machinery equipment is worked, blow out from drifting dust aperture or blowing groove by the clean compressed gas in the annular drifting dust cavity in the dust guard; After forming dustproof air curtain; Lens protecting cap open prevent dust or dust before lens protecting cap is opened near labelling head; Influence the mark quality, after the camera lens protective cover when machine stops mark in the device was closed in advance, air curtain was closed owing to the evacuation procedure of the residual gas of Compressed Gas in gas circuit after a while.
