Static Neutralization Equipment
|Controlled ion balance by sensor
3 types of the sensors are available.
Rapid neutralization of static electricity
Detects the polarity of a discharged object and measures the charged voltage.
Rapid neutralization of static electricity by a feedback sensor
The speed of static neutralization has been increased by reading the workpiece’s electrostatic potential by the feedback sensor and continuously emitting ions with a reverse polarity.
Run mode after static neutralization (ion balance: within ±30 V) can be selected.
■Energy saving run mode
Stops generating ions after static neutralization
to reduce power consumption. Air consumption can
also be reduced by controlling the pneumatic valve with
a static neutralization completion signal.
Note) The pneumatic valve must be separately procured.
■Continuous static neutralization run mode
After static neutralization, the ionizer changes to pulse DC mode and continues to neutralize static electricity to make it approach 0 V even if the ion balance is below 30 V.
Reduction of adjustment and maintenance labor
Measures the ion balance condition.
Autobalance sensor [High-precision type]
・The ion balance near the workpiece is accurately adjusted.
・The object is not affected by the height of installation or any disturbance interference.
・"Ion balance adjustment at external signal input" or "Ion balance adjustment at any time" can be selectable.
・The autobalance sensor may be connected only when adjusting the ion balance.
Autobalance sensor [Body-mounting type]
■Autobalance sensor [Body-mounting type] can be mounted on the body, and can be installed in any places.
Monitoring the amount of ion emitted from an ionizer, the autobalance sensor maintains the initial ion balance by adjusting the +/‒ ion supply rate.
|Electrode cartridge variations
Electrode cartridge with rapid neutralization of static electricity
■Focusing on static neutralization time and energy saving
・High-efficiency nozzle design improves discharge time with low air consumption.
3 types of electrode needle materials
・Tungsten: Ion balance ±30 V
・Single crystal silicon: Ion balance ±30 V, suitable for neutralizing static electricity of silicon wafer.
・Stainless steel*: Ion balance ±100 V, low-cost type, suitable for environments sensitive to heavy metal contamination such as food processing.
*Only for electrode cartridge with rapid neutralization of static electricity
Applicable to workpiece moving at high speed
Switching over frequency: Max. 60 Hz
Ions are discharged at high density at workpieces moving at high speed.
Continuous ion emission of a desired polarity during DC mode
Can be used to neutralize static electricity from fast-charged or high-potential wokpieces or to electrostatically charge them.
Detects the electric potential difference and outputs in an analog voltage.
(During sensing DC mode)
Outputs measured data at a 1 to 5 V level when a feedback sensor is used.
By outputting the data to a PLC, etc., it is possible to control static electricity.
