Among the magnetization unit is arranged in to rotary platform 3, can be rotated by left step motor, have two transform states of level and perpendicular, can empty unnecessary magnetic powder to the recovery box of below in, rotary platform 3 is last to have placed the splint and to fix the encryption paper.
The magnetizing device 4 is composed of a magnetic yokeAnd a magnetizing coil. The magnetic powder spraying device can adjust the height and the magnetic flux leakage control size. In which black magnetic powder Fe is filled3O4And magnetic powder is uniformly scattered on the encrypted paper to form magnetic marks through the transverse movement of the magnetic leakage holes and the stepping motor. The magnetic mark is an image of magnetic powder aggregation which can be seen by naked eyes, and can also be called magnetic mark display or display for short, wherein the magnetic mark display has an amplification effect on the width which is multiple times of the actual defect width, so that pattern information which can not be seen visually can be displayed by magnetic powder detection.
The image acquisition card 6 adopts an analog acquisition card. The analog video source camera is connected with a main control computer 7 provided with an image acquisition card 6 to form a hardware environment for image acquisition.
The main control computer 7 is provided with an upper computer control interface to facilitate man-machine operation, and sends an instruction to LPC2103 serving as a lower computer through a serial port communication module to drive the micro stepping motor to move the magnetic powder spraying device 5 at a constant speed and rotate the rotary platform 3.
As shown in fig. 3: the main procedures of the device are four, including feeding, strong magnetism, powder spraying and collecting.
Firstly, a system switch is turned on to be electrified, the bar-shaped LED 1 light source works to irradiate the rotary platform 3 to supplement light, and paper is placed on the platform and is reinforced by the clamping plate.
Then, the encrypted paper fixed on the rotary platform 3 is detected, the magnetizing device 4 consisting of the magnet yoke and the magnetizing coil is electrified to generate a magnetic field, and the encrypted paper is subjected to strong magnetic treatment so as to facilitate magnetic powder adsorption.
Then, an upper computer control interface of the main control computer 7 sends out a command, and a lower computer drives the micro stepping motor, so that the magnetic powder spraying device sprays black magnetic powder Fe to the encrypted paper after strong magnetism at a constant speed3O4Then, a magnetic mark is formed by covering. The magnetic marks are images of magnetic powder aggregation which can be seen by naked eyes, have amplification effect on the width, are multiple times of the actual defect width, and can display invisible pattern information.
At this time, the lower computer drives the micro stepping motor in the rotating platform 3 to rotate until the micro stepping motor is in a vertical state, so that redundant magnetic powder is poured into a recovery box below the lower computer, and then the lower computer rotates to return to the original position again. And finally, the CCD camera 2 is used for collecting images, and the collected image data can be transmitted to a main control computer 7 through an image collecting card 6 for storage and subsequent identification processing.
As shown in fig. 4: the lower computer LPC2103 is powered by double power supplies, namely 1.8V kernel voltage and 3.3V functional peripheral voltage. The 5V power is input by a transformer or a USB power line, and the circuit adopts SPX1117 series LDO chips SPX117M-3.3 and SPX1117M-1.8 to stabilize the voltage to 3.3V and 1.8V, and a 0 omega resistor is used for isolating a digital power supply from an analog power supply and for isolating the digital power supply from the analog power supply and from a digital ground and an analog ground.
As shown in fig. 5: LPC2103 contains two asynchronous serial ports: UART0 and UART 1. Since the serial port of the PC is RS-232 level, the standard high level is negative logic, and the low level is positive logic, and the UART and PC communication mode needs an SP-232 converter to convert signals into RS-232 level. The PC end is connected by adopting a DB9 connector.
