Description
Technical field
The present invention relates to the ion blower field, particularly a kind of dust collection method of ion transmission probe.
Background technology
Ion blower is a kind of device that negative ions is eliminated static on the electrostatic sensitive components and parts production line that produces.Generally, industry is main according to following two indexs to the performance of ion blower, the one, the degree of balance of negative ions (describing) with balanced voltage, be the amount of positive ions of ion blower generation and the deviation of anion quantity, this deviation is more little, illustrate that amount of positive ions and anion quantity are approaching more, balanced voltage approaches zero more, the performance of ion blower is just good more, because unbalanced negative ions can produce residual voltage in needs and on the components and parts of static, cause the static discharge harm that adds.Another index is die-away time, promptly under the effect of ion blower, a certain high voltage decays to a certain needed time of fixedly low-voltage, in order to weigh ion blower produces ion in the unit interval quantity (ion concentration), this die-away time is short more, illustrate that the ion that ion blower produces in the unit interval is many more, neutralising capacity is strong more, thereby the performance of ion blower is just good more.
Please refer to Fig. 1, is a kind of decomposition texture schematic diagram of prior art ion blower.This ion blower 100 comprises dc powered fan 1, ion transmission probe 2, positive or negative high voltage generator 3, control circuit board 4 and the housing 5 that holds above-mentioned parts.Wherein, this control circuit board 4 is given positive or negative high voltage generator 3 with low-voltage signal, this positive or negative high voltage generator 3 is given this ion transmission probe 2 again with the high pressure that produces, and neutral molecule or the atom of this ion transmission probe 2 in the corona phenomenon ionized air produces negative ions.These ions arrive station through the transfer function of fan, in and static on the components and parts, thereby arrive the purpose of eliminating static.
Please refer to Fig. 2, the ion blower that is Fig. 1 is for exchanging the working state schematic representation of ion blower.Exchanging the ion blower its working principles is that electric main (220 volts) is directly boosted to high pressure (without rectifying and wave-filtering), then this high pressure is added on the ion transmission probe 2, produces ion through corona phenomenon.At the positive half cycle of ac high-voltage, the anion that produces through corona phenomenon can be adsorbed to (there is a natural attraction between the sexes) on the ion transmission probe 2, and cation can be ostracised and be held (same sex is repelled each other), is finally blown on the station by fan.Equally, at the negative half period of ac high-voltage, the cation that produces through corona phenomenon can be adsorbed on the ion transmission probe 2, and anion can be ostracised and be held, and is finally blown on the station by fan.Those are adsorbed on charged granule on the ion transmission probe and can be subjected to the repulsive force that the same sex repels each other at next cycle and leave ion transmission probe.
On the whole, can not accumulate airborne charged granule on the ion transmission probe of interchange ion blower.But because the reason of alternation high pressure, exchange the ion wind chance in-plant hardware (comprising the components and parts that need antistatic) is produced very strong electric field induction (control has a negative impact to static discharge), so the interchange ion blower of this type only obtains in low side antistatic field to use.
For overcoming the weakness that exchanges ion blower, the ion blower of the second generation has adopted DC techniques, and DC techniques can be divided into two kinds again, and a kind of is the pulsed direct-current ion blower, and another kind is the stable state direct-current ion blower.Ion transmission probe in the direct-current ion blower is divided into two parts, and a part is the cation emission needle, and another part is the anion emission pin.
Please refer to Fig. 3, the ion blower that is Fig. 1 is the working state schematic representation of pulsed direct-current ion blower.The basic principle of pulsed direct-current ion blower is that electric main (220 volts) is generated direct current through rectifying and wave-filtering, boost into the pulsed high direct voltage again, the malleation of pulsed high direct voltage partly is added to (do not have making alive on the anion emission pin this moment) on the cation emission needle, and malleation partly finishes the back negative pressure of follow-up generation partly is added to (do not add point voltage on the cation emission needle this moment) on the anion emission pin.
Please refer to Fig. 4, the ion blower that is Fig. 1 is the working state schematic representation of stable state direct-current ion blower.The basic principle of stable state direct-current ion blower is that electric main (220 volts) is generated direct current through rectifying and wave-filtering, divide two-way to boost again, generate positive high voltage and negative high voltage, be added in respectively on cation emission needle and the anion emission pin, independent and produce cation and anion simultaneously.
In a word, pulsed direct-current ion blower and stable state direct-current ion blower can both improve the problem of " electric field induction ", but, the design of pulsed direct-current ion blower and stable state direct-current ion blower, all be on fixing ion transmission probe, to add the fixedly voltage of polarity, so just cause airborne charged granule to be accumulated on the ion transmission probe.When taking care of the pence, these granules will influence the Electric Field Distribution of corona phenomenon, and then the efficient of influence generation ion, and cause the negative ions imbalance.
