Spray head lifting locating method

Abstract

The invention discloses a spray head lifting locating method. The two opposite sides of a mounting rack are mounted on two lifting guide frames (1); spray heads are mounted on the mounting rack; a ball screw (2) is arranged on each lifting guide frame; the number of the lifting guide frames and the number of the ball screws are each two, and the two ball screws are mounted on the two lifting guideframes correspondingly; the two ends of the mounting rack are mounted on the two ball screws in a sleeved manner; when servo motors rotate, the mounting rack and the spray heads can be driven throughtransmission of the ball screws to ascend and descend; a tilt angle sensor used for detecting the tilt angle of the mounting rack is arranged on the mounting rack; the two ball screws are driven by the two independent servo motors (6) correspondingly; the tilt angle sensor is connected with an MCU; the servo motors are controlled by the MCU; and the MCU controls the height of the mounting rack and the height of the spray heads by controlling the servo motors, and lifting locating of the spray heads is achieved. According to the spray head lifting locating method, the locating precision is high, and implementation is easy.

Description

technical field [0001] The invention particularly relates to a method for lifting and positioning a nozzle. Background technique [0002] The biggest problem with the existing nozzle lifting and positioning is that the positioning accuracy is not high. In addition, if high-precision positioning is to be achieved, the positioning accuracy of printing even the whole process of lifting and lowering is required. 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 positioning method. Contents of the invention [0004] The technical problem to be solved by the pr...
