Method for precisely balancing Z-axis weight in real time

Abstract

The invention relates to a method for precisely balancing Z-axis weight in real time. The method comprises the steps that: a linear motor module drives a Z-axis movement module to move a certain distance; after the Z-axis movement module is stabilized, a grating ruler reading head reads first position data of a grating ruler and records the first position data into adjustment software, and the Z-axis movement module continues to fall; the adjustment software gives a pressure increase signal to a precision electric proportional valve, a rodless cylinder body is slowly filled with gas, and a rodless cylinder slider drives the Z-axis movement module to move up; the grating ruler reading head reads second position data of the grating ruler and compares the second position data and the first position data, and the second position data and the first position data are the same, the adjustment software reads pressure data of the precision electric proportional valve and records the pressure data when the position is stable; in the next time of equipment starting and operation, the adjustment software increases the pressure of the rodless cylinder body according to the automatically measured pressure data so as to balance gravity. According to the method, the judgment and adjustment are automatic, shutdown is not needed, and the Z-axis movement module reaches a balanced state.

Description

technical field [0001] The invention relates to the field of automation equipment, in particular to a method for precisely balancing Z-axis weight in real time. Background technique [0002] With the development of economy and technology, automation equipment is more and more widely used in industrial production. In the direct drive technology of linear motors, there are two difficulties in using pneumatic and hydraulic methods to balance gravity: first, the current The commonly used method is to adjust the air pressure and oil pressure through manual adjustment and experience judgment. It needs continuous trial adjustment and the result of adjustment is to judge the problems of poor consistency of equipment, strong dependence on personnel, low efficiency and poor accuracy through experience. . Secondly, when the load of the Z-axis mobile module changes, it is necessary to stop the machine for manual adjustment and adjust the air pressure and oil pressure through empirical ...

[0002] With the development of economy and technology, automation equipment is more and more widely used in industrial production. In the direct drive technology of linear motors, there are two difficulties in using pneumatic and hydraulic methods to balance gravity: first, the current The commonly used method is to adjust the air pressure and oil pressure through manual adjustment and experience judgment. It needs continuous trial adjustment and the result of adjustment is to judge the problems of poor consistency of equipment, strong dependence on personnel, low efficiency and poor accuracy through experience.

Secondly, when the load of the Z-axis mobile module changes, it is necessary to stop the machine for manual adjustment and adjust the air pressure and oil pressure through empirical judgment. It is necessary to adjust the motion parameters again
