The scanning inkjet printer board includes two boards, a USB 3.0 data transmission board (hereinafter referred to as USB board) and a nozzle control board (hereinafter referred to as head board). The two boards are connected through optical fibers. The USB board is connected to the computer through a USB 3.0 interface, and the head board is responsible for driving the nozzle.

The picture of the USB board is as follows:

The specific functions of the USB board are as follows:

1. Receive the image data and print command sent by the printing software through the USB 3.0 interface, and send the image data and print command to the head board.

2. Send the card parameters of the USB board and head board to the printing software through the USB 3.0 interface.

3. The USB board provides three motor interfaces, and the printing software controls the three motors of the device through the motor interface of the USB board.

4. The USB board provides 8 ink pump interfaces, which can automatically control the ink supply function of the ink in cooperation with the liquid level detection function of the head board.

5. The USB board provides two UV lamp control interfaces, which can drive the UV lamp to automatically switch with printing.

6. The USB board provides four optical fiber interfaces, which can connect four head boards.

7. The USB board provides an input interface to receive the limit switches in each movement direction.

8. The USB board provides two differential input interfaces, which can receive encoder signals and motor feedback pulse signals.

The picture of head plate is as follows:

The specific functions of the head plate are as follows:

1. Receive the image data and print command sent by the printing software through the USB board, send the image data to the nozzle, and control the nozzle to eject ink from the nozzle as required through the voltage waveform.

2. The USB board is connected through optical fiber, and the transmission speed is as high as 1.25gb/s, which ensures that the device can transmit data in real time under high-speed printing.

3. The liquid level detection interface of the head board is responsible for detecting the liquid level of the ink cartridge of the equipment, and cooperating with the ink pump interface of the USB board to realize automatic ink supply.

4. The motor interface of the head plate controls the z-axis motor of the equipment to move up and down.

5. The single end grating input of the head plate and the differential grating input receive the grating input of the device.

6. The height measurement input of the head plate and the output of the solenoid valve cooperate with the movement of the z-axis motor to realize the automatic height measurement function.

7. The head board has left and right limit input and upper and lower limit input functions.

8. The head plate has trolley anti-collision function.

9. The head plate has four adapter plate interfaces, which can drive different inkjet nozzles by replacing and adapting different nozzle adapter plates.

10. The head plate can now drive four G6, G5, g5i nozzles, or eight small Ricoh nozzles.
