A kind of dustless print systemTechnical field
The present invention relates to a kind of protector of printer.
Technical background
Along with the development of printing technique, inkjet printing is applied to industrial production gradually.In commercial Application, in order to ensure the quality of products, require product to process in dust free room.
Dust free room is not definitely dustless, but in certain dustless grade.Its object is just not contaminated in process in order to ensure workpiece, or pollution level is controlled in tolerance interval.
For example: in current PCB manufacturing process, processing circuit dry film and welding resisting layer all need to carry out at dust free room.
Present dust free room, as processing site, needs expensive construction cost, personnel need to dress cleanness clothing, needs pre-dedusting just can enter, need a large amount of dustless wind supplies and consume a large amount of energy.
Summary of the invention
Content of the present invention is: for printing the deficiency that need to carry out at dust free room, provide a kind of without the dustless print system in traditional dust free room work.
The present invention has following technical characterictic.
A kind of dustless print system, comprises dust free room, it is characterized in that: dust free room provides dustfree environment for print procedure.
The dustfree environment that described dust free room provides, is characterized in that: dustfree environment is to reach to print the dustless grade requiring.
The dust free room of described dustless print system, is characterized in that: without dust hood and printing table top composition dust free room.This will provide the dustfree environment of a small dimension for printer.
The dust free room of described dustless print system, is characterized in that: dust free room is the casing that can hold printer, and printer is positioned at dust free room inside.Printer is directly put in a dustless case, and this is simple directly method.
The dust free room of described dustless print system, is characterized in that: dust free room is not airtight.Because workpiece need to pass in and out dust free room, so that dust free room needs not to be is airtight.
The dust free room of described dustless print system, also comprises air inlet, it is characterized in that: dustless gas enters dust free room by air admission hole, and the air pressure in dust free room is malleation with respect to the air pressure outside dust free room.The air of dust free room outside can not enter dust free room the inside and cause processing environment contaminated.
It is characterized in that: the gas that enters dust free room from air inlet is protective gas or ink cured gas or special gas.When gaseous environment being had to requirement in print procedure, desired gas can enter dust free room by air inlet so.For example: inert gas enters dust free room from air inlet, can prevent ink oxidized in print procedure.
The dust free room of described dustless print system, also comprises air flow guiding device and/or structure, it is characterized in that: avoid the inner strong air flow that produces of dust free room.For fear of violent Air Flow, on the impact of printing, dustless gas should just enter dust free room through suitable distribution, guarantees that the air-flow in dust free room relaxes, and in barotropic state.
Described dustless print system, also comprises dust free room dust pelletizing system, it is characterized in that: dust pelletizing system provides source of the gas for dust free room.So just need to not provide source of the gas by other dust pelletizing system.
Described dustless print system, also comprises workpiece dust pelletizing system, it is characterized in that: before workpiece enters dust free room, workpiece is carried out to dedusting.If surface of the work is contaminated, workpiece dust pelletizing system can be removed before workpiece enters dust free room, and while guaranteeing to print, surface of the work is not contaminated.
Compared with prior art, the invention has the advantages that: do not need to build dust free room, operating personnel and do not need to dress cleanness clothing, the only a small amount of dustless gas supply of need.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Embodiment mono-: as shown in Figure 1, be positioned on printermain body 30 withoutdust hood 20,cover plate 10 is positioned at without ondust hood 20, forms dust free room withoutdust hood 20 and stamp pad 31.Ink-jet system 32 prints within dust free room.
Clean air is entered bydustless air inlet 11, then passes throughair distribution plate 21, just enters dust free room.Maintain dust free room and keep malleation, pollutant can not enter with air.
Onair distribution plate 21, have air-vent 22, air-vent 22 is because position difference and size difference, and uneven distribution.Airflow passesair distribution plate 21, air-flow will can not impact inkjet printing.
Havingair knife 23 without the front end ofdust hood 20, compressed air entersair knife 23 by highpressure admission mouth 24, and before workpiece enters dust free room, the gases at high pressure thatair knife 23 sprays are cleared up workpiece, avoid pollutant effect print result.
Embodiment bis-: as shown in Figure 2, dust free room forms a casing byupper cover 41 andbase 42, and printer main body is positioned at box house.Dust-free air enters box house byair admission hole 43, maintains the malleation in casing.The two ends of stamp pad are positioned at outside casing, can, in the directly loading and unloading of casing outside, print operation.
It is to be understood that: although above-described embodiment has done more detailed text description to the present invention, these text descriptions, just describe the simple text of mentality of designing of the present invention, rather than restriction to invention mentality of designing.Any combination, increase or the modification that does not exceed thinking of the present invention, the especially optimization to dust free room structure, all fall into protection scope of the present invention.
