In addition, the probe 320 is a vibration potential sensor, and axial vibration is generated between electrodes of the vibration potential sensor under the action of a driving signal, so that an effective area between the vibration potential sensors generates a waveform with a sine or cosine law, thereby generating periodic capacitance change, and extracting a value at a certain moment, which is a potential difference (voltage value) of an electrostatic field. This charge generator can send the ion at the in-process of work, sends the back at the ion, can keep static at the minimum and carry the electric quantity, reaches a relative balanced state this moment, and this balanced state is for making the insulator surface of inflammables not taking charge, and then makes not produce the electrostatic field.
It should be noted that, firstly, the system utilizes the longitudinal moving mechanism 3 to adjust the height of the clamping plate 317 through the third cylinder 307 so as to adjust the clamped height to clamp the inflammable substance, thereby completing the linear movement in the Z-axis direction, and then the second cylinder 306 pushes the buffer block 305 under the action of the guide rod 302 and the linear bearing, and in the first direction (set as the X-axis direction), the system utilizes the first driving motor 202 to drive the first gear 204, thereby driving the second direction moving mechanism and the longitudinal moving mechanism to move in the X-axis direction. In the Y-axis direction, the system drives the longitudinal moving mechanism to complete the linear motion in the Y-axis direction by using the third driving motor 206 under the action of the gear and the rack, and when clamping the inflammable substance, the second driving motor 310 is used to drive the second gear 311 and the second rack 313, the clamping plate 317 is driven under the action of the third linear guide rail 316, the clamping plate 317 clamps the inflammable substance, and the carrying process can be completed by the movement in the three directions and the clamping movement until the inflammable substance is carried to a specified position or moved to a carrying point, so that the inflammable substance is carried out from the assembly line to a truck or other specified positions. In the process of carrying, the system starts the movable guide rail 318 on the adsorption plate 315, blows out ion wind on the surface of the inflammable substance through the air pipe, and neutralizes static electricity on the insulator material of the inflammable substance under the action of the movable guide rail 318 driving the air port plate.
The second aspect of the present invention provides a method for using a transfer robot system for combustibles, which is applied to any one of the transfer robot systems for combustibles, and comprises the following steps:
s102, acquiring a charge signal fed back by a probe;
s104, determining a potential signal according to the charge signal to obtain electrostatic potential information;
s106, comparing the potential information with preset potential information to obtain a deviation ratio;
s108, judging whether the deviation rate is smaller than a preset deviation rate threshold value or not;
s110, if the air quantity is smaller than the preset value, opening an air pipe, and starting a charge generator;
and S112, if not, the charge generator is not started.
It should be noted that, when the signal of the static electricity is generated, it can be understood that an electrostatic field is generated between the static electricity at this time, and the preset potential information can be understood as an electric field in which the potential difference tends to 0, and the electric field is detected by the probe due to the electric field generated between the positive charge and the negative charge between the static electricity. When an electric field is generated, the deviation ratio at this time can be understood as the value of the electric field actually generated. During detection, the sum of electric field values generated within a preset time is fluctuated by adopting a preset time, the average value of the electric field values (potential difference) generated within the preset time is taken as a reference, and the positive charge or the negative charge on the surface of the inflammable substance is neutralized by the ionic wind discharged from the air pipe.
Further, in a preferred embodiment of the present invention, the determining a potential signal according to the charge signal to obtain potential information specifically includes the following steps:
s202, acquiring a potential difference between the charge generator and a measured object;
s204, obtaining an initial voltage signal through the potential difference to obtain an initial voltage signal;
s206, amplifying the initial voltage signal and filtering useless signals in the voltage signal to obtain a secondary processing voltage signal;
and S208, carrying out phase-sensitive detection processing on the secondary processing signal to obtain electrostatic potential information.
It should be noted that, the secondary processing voltage satisfies the following relation:
wherein,
the voltage value of the static electricity is in volts; z is the capacitance between the probe and the measured object and has the unit of farad;
the ground is taken as a potential point 0, and the potential difference of the average static electricity between the ground and the object to be measured is obtained; z is a radical ofkIs around the probeThe inductive capacitance of (2); i is a constant, and the value of the constant is a natural number e.
It should be noted that the secondary processing voltage signal is a voltage value of static electricity, and the static electricity on the surface of the object to be measured is attenuated according to an exponential law and a law that e is a constant, so that during measurement, the voltage average value in the time of detecting the static electricity is taken to obtain the average charge size of the static electricity of the object to be measured, and then the static electricity is obtained as positive charge or negative charge through the phase sensitive detector. Specifically, a periodic signal with a sine rule is generated by a charge generator to drive the vibrating capacitive potential sensor to vibrate periodically, so that a corresponding transformed current is generated in the sensor. The amplitude of the current is proportional to the potential of the charge carried by the object to be measured, and the phase of the current corresponds to the polarity of the charge. The current is converted into voltage through a resistor, the voltage is amplified and demodulated after frequency-selective amplification and a phase-sensitive detector, so that the electrostatic field voltage of the object to be measured is obtained, and the positive and negative of the measured voltage represent the electrostatic field voltage polarity of the object to be measured.
Further, in a preferred embodiment of the present invention, the electrostatic potential information includes a magnitude of a charge carried by the static electricity, and the charge carried by the static electricity is a positive charge or a negative charge.
In light of the foregoing description of the preferred embodiment of the present invention, it is to be understood that various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and the technology must be determined in accordance with the scope of the claims.
