US 2014/0111572 A1 · Inkjet Printing Positioning Device and Control Method Thereof

Abstract

This invention provides an inkjet printing positioning device and control method thereof. The inkjet printing positioning device comprises: base; linear guide rail fixedly mounted on the base; inkjet unit, moving in matched manner with the linear guide rail; ball screw, driving the inkjet unit to move linearly when being rotated; servomotor, for driving the ball screw to rotate; a zero position detecting device, mounted in a position on the moving travel route of the inkjet unit from the initial position to the printing area, and for sending zero position signal when detects that the inkjet unit is passing by; controller connecting the zero position detecting device and the servomotor, and for controlling the servomotor to drive the inkjet unit to move from the current position to the printing area and locate there, and controlling the servomotor to drive the inkjet unit to move predetermined displacement upon receipt of zero position signal.

An inkjet printing positioning device comprising:

a base;
a linear guide rail, which is fixedly mounted on the base;
a inkjet unit, which moves in a matched manner with the linear guide rail, further comprising:
a ball screw, which is used to drive the inkjet unit to move linearly when being rotated;
a servomotor, which is used to drive the ball screw to rotate;
a zero position detecting device, which is mounted in a position on the moving travel route of the inkjet unit from the initial position to the printing area, and used for sending a zero position signal when detects that the inkjet unit is passing by;
and
a controller, connecting the zero position detecting device and the servomotor, for controlling the servomotor to drive the inkjet unit to move from a current position to the printing area and locate there, and the controller controls the servomotor to drive the inkjet unit to move a predetermined displacement when a zero position signal is received by the controller.
