Description
Technical field:
The utility model belongs to the antistatic technique field, particularly a kind of circuit of controlling the direct-current ion blower degree of balance, and it is mainly used in and eliminates electrostatic charge in the industry production such as semiconductor packages, photoelectricity electronics, communication, injection moulding fast.
Background technique:
Modern industry is produced more and more higher to the requirement of production environment, and static discharge is one of principal element that influences quality of product in producing.Ion blower is a visual plant of eliminating electrostatic charge in the manufacturing shop fast, is a kind of iontron that the balance air-flow is provided, and is difficult for the static charge of contact area in the territory, erasable area.
Existing ion blower is made up of high-voltage power generator and discharging electrode, by high-voltage corona discharge air ionization is become a large amount of negative ions static with the corrective surface.And direct-current ion blower wherein mainly is by two groups of discharging electrode synchronized transmissions negative ions, and also transmitting anion in the emission positive ion is to reach the effect of eliminating static.
But because the negative ions self-neutralization ability that produces is stronger, when reaching certain zone, ion concentration then can weaken, will cause like this and eliminate static time length and need more ion populations, and then cause the skew of ionic equilibrium degree, exceed the balanced voltage of production requirement and can not adjust, influence quality of product.
Summary of the invention:
For addressing the above problem, the purpose of this utility model is to provide a kind of circuit of controlling the direct-current ion blower degree of balance, this circuit directly adopts the power supply signal of high direct voltage output to carry out degree of depth reverse feedback, reaches the highly stable of output voltage, thereby makes the ionic equilibrium degree highly stable.
The utility model proposes a kind of circuit of controlling the direct-current ion blower degree of balance, comprise high-pressure generator, to DC high-voltage power supply, feeder loop, drive circuit and the main control processor of high-pressure generator power supply, described feeder loop is connected with described DC high-voltage power supply, and the power supply signal of DC high-voltage power supply output is sent into described main control processor after the feeder loop sampling is handled; Described DC high-voltage power supply and described drive circuit are connected to form adjustable reference power supply.
Preferably: described circuit comprises operational amplifier and drive circuit; Described main control processor is exported to operational amplifier with control signal, and signal sends drive circuit to after amplifying via operational amplifier, controls described DC high-voltage power supply by drive circuit described high-pressure generator is powered.
The beneficial effects of the utility model are: compared to existing technology, the utility model directly adopts the power supply signal of high direct voltage output to carry out degree of depth reverse feedback, like this, main control processor can well be controlled the output voltage to high-pressure generator, make output voltage highly stable, thereby make the ionic equilibrium degree highly stable.
Description of drawings:
Fig. 1 is the utility model circuit module figure.
Fig. 2 is a circuit diagram of the present utility model.
Embodiment:
The utility model provides a kind of circuit of controlling the direct-current ion blower degree of balance, and its structure is referring to shown in Figure 1.This circuit comprises the high-pressure generator that is used for emitting ions wind, to the inductor of DC high-voltage power supply, feeder loop, main control processor, operational amplifier and the drive circuit balanced voltage of high-pressure generator power supply.
DC high-voltage power supply and drive circuit are connected to form adjustable reference power supply.Feeder loop one end is connected with DC high-voltage power supply, and the other end connects main control processor.Inductor can be responded to net for balanced voltage, and it is connecting main control processor, and the signal of collecting is passed to main control processor.The control signal of the output of main control processor passes to drive circuit after amplifying via operational amplifier, drives high-pressure generator by drive circuit control DC high-voltage power supply and produces ion.Simultaneously, feeder loop collects the power supply signal of the output of high-pressure generator, sends into main control processor after the feeder loop sampling is handled, and by main control processor high-pressure generator is controlled, is adjusted.
Referring to Fig. 2 circuit diagram.The first port J1 of main control processor and the second port J2.The first port J1 concatenation operation amplifier A drives high-pressure generator RF by the signal after the operational amplifier A processing via the drive circuit of being made up of the first power amplifier D, the second power amplifier B and triode C and sends ion wind.Because DC high-voltage power supply VDD is controlled by drive circuit, so its power to high-pressure generator RF output can change.DC high-voltage power supply VDD outputs to the second port J2 of main control processor simultaneously to the electrical signal of high-pressure generator RF output, main control processor is monitored the power of high-pressure generator RF by the electrical signal of monitoring DC high-voltage power supply, and then controls the degree of balance of ion wind.
More than a kind of circuit of controlling the direct-current ion blower degree of balance provided by the utility model is described in detail, used specific case herein principle of the present utility model and mode of execution are set forth, above embodiment's explanation just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
