The apparatus of claim 6, further comprising a detection circuit connected to the positioning assembly; a fixed detection head connected to the fixed baffle; the fixed resistor is electrically connected with the connecting terminal, the connecting terminal is electrified, and the other end of the fixed resistor is grounded; an operational amplifier electrically connected to the connection terminal and the fixed resistor; the oscillograph is electrically connected with the output end of the operational amplifier; the oscillograph measures the curve change of the voltage and transmits the curve change to the upper computer.
9. The apparatus for rapidly testing material uniformity according to claim 1, wherein said third conveying assembly comprises:
the second supporting piece is arranged on the workbench;
the second conveyor belt is arranged on the second supporting piece; and the section plate of the second conveyor belt is provided with a positioning groove for placing the metal plate.
10. The detection method of the device for rapidly detecting the uniformity of the material based on any one of claims 1 to 9, is characterized by comprising the following steps:
the method comprises the following steps that firstly, a metal plate is placed on a first conveyor belt to be conveyed, the metal plate slides to a second conveyor assembly under the action of the gravity of the metal plate at the tail end of the first conveyor assembly, the second conveyor assembly drives the metal plate to rotate to the vertical direction, a pushing assembly measures the distance from the pushing assembly to one end of the metal plate, and the metal plate is pushed to an appointed position;
according to the detection path of the preset foundation of the metal plate, namely the sliding path of the movable detection head on the surface of the metal plate,
step two, the clamping mechanism vertically clamps the metal plate at the designated position, and places the metal plate on the detection mechanism;
clamping the metal plate by the positioning assembly, detecting the metal plate by the detection circuit, wherein a fixed detection head of the detection assembly is fixedly connected with a certain position of the metal plate, the movable detection head slides on the other surface of the metal plate, the length and the thickness of the resistor and the material are linearly changed, the change of the resistor is converted into voltage signal change by the detection circuit, and the uniformity of the metal plate is indirectly analyzed by observing the change of the voltage signal;
and step four, after the detection is finished, the clamping mechanism clamps the metal plate and places the metal plate on a third conveying assembly for conveying and sorting.
