and the driver is used for adjusting the position of the driver according to the position value and correcting the deviation of the material.
In this embodiment, since a set of ultrasonic transceivers are adopted to detect edges in the prior art, which results in a small detection range and is not suitable for an application scene with a large range of variation of the edge position of the detected material, the three sets of ultrasonic transceivers are arranged in the ultrasonic sensor to collect the material edge position information of the material in real time and send the material edge position information to the deviation correcting controller, the deviation correcting controller generates the position value of the driver according to the material edge position information and sends the position value to the driver, and the driver adjusts the position according to the position value, so as to correct the deviation of the material.
In order to implement deviation correction on the material, in some embodiments of the present application, the ultrasonic sensor is electrically connected to the deviation correction controller, and the deviation correction controller is electrically connected to the driver.
In this embodiment, the ultrasonic sensor, the deviation rectifying controller and the driver are connected as shown in fig. 1, and it should be noted that in this scheme, the ultrasonic sensor, the deviation rectifying controller and the driver may be electrically connected, or may be connected by other forms by data communication, and the difference of connection modes does not affect the protection scope of this scheme.
To maximize the detection range, in some embodiments of the present application, three sets of the ultrasonic transceivers are placed in a stacked fashion on the ultrasonic sensor at a predetermined angle.
In this embodiment, the effective detection range of the ultrasonic transceiver is not a circular area of the outline, but is smaller than the outline, when three pairs of ultrasonic waves are used, if three circles are arranged in a tangent manner, gaps can occur in detection areas of the three groups of ultrasonic waves, when the material edge is in a change in the detection gaps, the sensor cannot detect the position of the material edge, so that the output value is not changed, which is equivalent to the situation that the edge enters a blind area, the three groups of ultrasonic transceivers are placed according to a schematic diagram as shown in fig. 2, the preset angle can be flexibly determined according to actual needs, the thickness, the model and the like of a specific sensor, and the blind area is removed in a stacking manner.
In order to acquire the material edge position information, in some embodiments of the present application, when detecting that two groups of ultrasonic waves on the inner side in the three groups of ultrasonic transceivers are not shielded, the outermost ultrasonic wave is effective, and the material edge position information corresponding to the outermost ultrasonic wave is sent to the deviation rectification controller; when the innermost ultrasonic waves in the three groups of ultrasonic transceivers are detected to be free from shielding, and the outermost ultrasonic waves are completely shielded, the middle ultrasonic waves are effective, and material edge position information corresponding to the middle ultrasonic waves is sent to the deviation correcting controller; when the outer two ultrasonic waves in the three groups of ultrasonic transceivers are detected to be completely shielded, the innermost ultrasonic wave is effective, and the material edge position information corresponding to the innermost ultrasonic wave is sent to the deviation correcting controller.
In order to further improve the accuracy of material edge detection, in some embodiments of the present application, the receiving end of each of the ultrasonic transceivers is further connected to an amplifying circuit, and each amplifying circuit includes at least one operational amplifier.
In this scheme, the receiving end of each ultrasonic transceiver is connected with an amplifying circuit, and one of the amplifying circuits is used for amplifying signals received by the receiving end of each ultrasonic transceiver, and the other is used for controlling the detection range of each ultrasonic transceiver.
To further adjust the detection range of each ultrasonic transceiver, in some embodiments of the application, the edge tangency of the detection range of each ultrasonic transceiver is controlled by adjusting the amplification factor of an operational amplifier in the amplification circuit.
In this embodiment, the effective detection range of the ultrasonic transceiver is not a circular area of the outline, but is smaller than the outline, when three pairs of ultrasonic waves are used, if three circles are arranged in a tangential manner, gaps can appear in detection areas of the three groups of ultrasonic waves, when the edge of the material is in a change in the detection gaps, the sensor cannot detect the position of the edge of the material, so that the output value is not changed, which is equivalent to the edge entering a blind area; if the blind areas are to be removed in a mode of stacking at a preset angle, an overlapping part is formed between two adjacent detection areas, and when the material edges are in the change of the overlapping areas, the sensor cannot detect the correct positions of the material edges, so that aiming at the phenomenon that the detection areas overlap, the amplification factors of the operational amplifiers of the amplifying circuit are adjusted to adjust the detection range of each group of ultrasonic waves, so that the edges of the detection ranges are tangent, and the overlapping areas are removed.
To achieve tangency of the detection regions, in some embodiments of the present application, when there is overlap between the detection ranges of the ultrasonic transceivers, the detection ranges of the ultrasonic transceivers are narrowed, and when edges of the detection ranges of the ultrasonic transceivers are tangency, the amplification factors of the operational amplifiers are increased, and the outputs of the operational amplifiers are maximized.
In the scheme, the signal received by the ultrasonic wave is amplified by the operational amplifier, the highest amplifying capacity of the operational amplifier is output as the power voltage of the operational amplifier, when the detection area is completely shielded, the receiving end has no signal, the output value of the operational amplifier is 0V, when the detection area is slowly moved away from the whole shielding area, the operational amplifier outputs a corresponding voltage value according to the set amplification factor, if the amplification factor of the operational amplifier is increased at the moment to enable the amplification factor to output the maximum value, the area of the shielding detection area is continuously moved away from the area, the output of the operational amplifier keeps the maximum value unchanged, and the detection area equivalent to the detection area after the operational amplifier outputs the saturated voltage is invalid, so that the detection area of the ultrasonic wave is reduced.
In order to adjust the detection area, in some embodiments of the present application, each of the amplifying circuits further includes a potentiometer for adjusting the amplification factor of the operational amplifier.
