Spray head lifting and positioning mechanism and printing device

Abstract

The invention discloses a spray head lifting and positioning mechanism and a printing device. The spray head lifting and positioning mechanism comprises lifting guide frames (1), ball screws (2) and aservo motor (6); a spray head is mounted on a mounting frame; the lifting guide frame and the ball screw are both two, and the two ball screw rods are arranged on the two lifting guide frames respectively; the two ends of the mounting frame with the spray head are sleeved with the two ball screw rods; each ball screw is driven by the servo motor (6); when the servo motor rotates, the mounting frame and the spray head can be driven to ascend and descend through the transmission of the ball screw; the mounting frame is provided with an inclination angle sensor used for detecting the inclinationangle of the mounting frames; the two ball screws are driven by two independent servo motors respectively; a tilt angle sensor is connected with a MCU; and the servo motor is controlled by the MCU. The spray head lifting and positioning mechanism and the printing device are compact in structure, high in positioning precision and easy to implement.

Description

technical field [0001] The invention particularly relates to a nozzle lifting and positioning mechanism and a printing device. Background technique [0002] The biggest problem with the existing nozzle lifting and positioning is that the positioning accuracy is not high. In addition, if you want to achieve high-precision positioning, you need to print the positioning accuracy even in the whole process of lifting. The structure of such a large stroke and the positioning accuracy of ordinary machine tools Similarly, processing with ordinary machine tools is difficult to achieve, the difficulty of processing, the difficulty of assembly, and the cost of fixtures are all geometric multiples of ordinary machine tools. Therefore, it is necessary to design a new positioning scheme with low cost and high positioning accuracy. [0003] Therefore, it is necessary to design a nozzle lifting and positioning mechanism and a printing device. Contents of the invention [0004] The techni...
