Problems solved by technology

Due to the existence of some mechanical transmission parts with large response time constants (such as lead screws, etc.), the dynamic response performance of the entire closed-loop control system is low, and the response is not sensitive enough.
[0003] Due to the transmission gap and error generated by the mechanical mechanism such as the screw, the tracking error is caused by the lag of the transmission system, and the positioning accuracy of the equipment is very low.
[0004] When the equipment is started, shifted and reversed, the movement hysteresis is caused by the elastic deformation, friction and wear and backlash of the intermediate transmission link, and the transmission stiffness is low
[0005] Due to the mechanical friction of the transmission screw and other components, the noise is very loud during movement, the energy loss is large, and the transmission efficiency is very low.
[0006] The traditional single mover module has low movement efficiency and high manufacturing cost

Abstract

The invention discloses a double-module alternate moving linear motor module. A module mounting base comprises a vertically arranged mounting plate; a linear motor stator is mounted on the front side surface of the mounting plate; two linear guide ways are mutually parallelly mounted on the front side surface of the mounting plate, and are respectively positioned above the linear motor stator and below the linear motor stator; a left side linear motor coil rotor is fixedly mounted on the back side surface of a left side rotor mounting plate; a right side linear motor coil rotor is fixedly mounted on the back side surface of a right side rotor mounting plate; a plurality of guide way sliding blocks are fixedly connected to the back side surface of the left side rotor mounting plate and the back side surface of the right side rotor mounting plate, and are very stably connected with the linear guide ways; the right side rotor mounting plate is positioned on the right side of the left side linear motor coil rotor; a grating ruler is mounted below the linear motor stator. According to the double-module alternate moving linear motor module, the movement efficiency is improved, the manufacturing cost is greatly reduced, and the dynamic response performance of a whole closed-loop control system is greatly improved.

Description

technical field [0001] The invention relates to a processing equipment using a double-mode alternating motion linear motor. Background technique [0002] The traditional rotary motor + ball screw motion system has a mechanical transmission link from the motor to the main working module, and the length of the transmission chain is very long. Due to the existence of some mechanical transmission parts with large response time constants (such as lead screws, etc.), the dynamic response performance of the entire closed-loop control system is low, and the response is not sensitive enough. [0003] Due to the transmission gap and error generated by the mechanical mechanism such as the lead screw, the tracking error is caused by the lag of the transmission system, and the positioning accuracy of the equipment is very low. [0004] When the equipment is started, shifted and reversed, the movement hysteresis is caused by the elastic deformation, friction and wear and backlash of the ...
