Problems solved by technology

The Z-axis loading platform requires that the platform can be accurately positioned at any time within a certain range of travel, so as to meet the movement and processing requirements of the machine; its repeat positioning accuracy is generally ±3-5um, which is far from meeting the requirements of picosecond laser fine processing equipment. Lifting accuracy requirements

Abstract

The invention relates to a high-precision Z-shaft carrier platform of picosecond laser process equipment. A Z fixed plate is fixed on the base plate of a Z platform, a vertical guide rail is installedon the Z fixed plate, an elevating plate capable of moving upwards and downwards along the guide rail is installed on the guide rail, a piezoelectric ceramic motor for controlling the elevating plateto move upwards and downwards is installed on the base plate of the Z platform, a vertical front side plate is fixed on the front side surface of the elevating plate, a vertical back side plate is fixed on the back side surface of the elevating plate, and the front side plate and the back side plate are arranged symmetrically in parallel; a sensor is arranged on the Z fixed plate, and the internal surface of the front side plate or the back side plate is provided with a sensing plate of the sensor; a reading head is arranged on the Z fixed plate, and a grating gage is stuck to the internal surface of the front side plate or the back side plate; and fixture plates are arranged on the front side plate and the back side plate. The high-precision Z-shaft carrier platform of the picosecond laser process equipment controls the Z-shaft to start, stop and elevate by using the high-resolution piezoelectric ceramic motor. The grating gage ensures the precision of elevation and positioning. Thebalancing mechanism solves the problems of insufficient thrust and static retaining force of the piezoelectric ceramic motor.

Description

technical field [0001] The invention relates to picosecond laser finishing equipment, in particular to a high-precision Z-axis object-carrying platform of the picosecond laser processing equipment. Background technique [0002] At present, in laser fine processing equipment, the Z-axis loading platform is generally driven by the motor rotation to move the ball screw to perform linear motion, and then the linear motion of the ball screw drives the loading platform to realize vertical lifting. The Z-axis loading platform requires that the platform can be accurately positioned at any time within a certain range of travel, so as to meet the movement and processing requirements of the machine; its repeat positioning accuracy is generally ±3-5um, which is far from meeting the requirements of picosecond laser fine processing equipment. Lifting accuracy requirements. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the pri...
