Single-axis displacement machine

Technical parameters

A single-axis displacement machine,also known as a single-axis linear stage,is a device that provides precise automated positioning along a single axis of motion.Here is a detailed introduction:

Structural composition:

Base and moving platform:The base remains fixed,serving as the support foundation of the entire device.The moving platform moves along a guided path,and the work-piece or other components can be installed on it.

Motion mechanism:Common ones include ball screws or lead screws.As the screw rotates,the nut on the screw converts rotational motion into linear motion,pushing or pulling the platform to move.Linear motors are also used in some high-end models.They directly generate force to the moving platform without mechanical transmission parts,enabling smoother motion.

Guiding system:Usually composed of linear guides or bearings,such as crossed-roller bearings.Its function is to ensure the smooth and accurate movement of the platform and prevent deviation from the specified path.

Feedback system:Encoders or sensors are often used to monitor the position of the moving platform in real-time and provide feedback to the control system,so that the system can make timely adjustments to achieve precise positioning.

Working principle:Driven by a stepper motor or servo motor,through the transmission of the motion mechanism(such as ball screw or synchronous toothed belt),combined with the guidance of the guiding system,the moving platform moves linearly along a single-axis direction,so as to realize the functions of handling,positioning,and transferring in a specific direction.

Features:It has the characteristics of good follow-up performance,high stability,and high-precision positioning.For example,some high-end single-axis displacement machines can achieve a repeatability accuracy of up to 1μm.Moreover,it has a compact structure,is easy to install and maintain,and can be equipped with a variety of controllers for operation.

Application fields:Widely used in fields requiring high-accuracy positioning and smooth motion,such as microscopy and imaging,DNA sequencing and genomics,optical metrology,and cell analysis and sorting.In addition,it also has a large number of applications in the positioning,handling,and detection links of the liquid crystal panel,semiconductor,home appliance,and automotive industries.
