Embodiment Construction

[0040] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings. It should be noted that the following embodiments are intended to facilitate understanding of the present invention, but do not limit it in any way.

[0041] In this example, if figure 1 As shown, the one-dimensional precision positioning platform includes a voice coil motor 1 and a guiding mechanism. The guiding mechanism is composed of a first guiding mechanism 2 and a second guiding mechanism 3 .

[0042] Such as figure 2 As shown, the voice coil motor has an axial hollow structure, including a mover and a stator. The mover includes a wire frame 14 and a coil wound on the wire frame. Such as image 3 As shown, the wire frame is an axially hollow cylindrical structure, and a groove structure 30 is provided on the outer surface for winding the coil. Four axial protruding blocks 29 of the same shape and size are respectively arranged o...

Abstract

The invention provides a hollow type one-dimensional precise positioning platform. A voice coil motor and guide mechanisms are designed into axial hollow structures; the guide mechanisms are axially arranged at the two ends of the voice coil motor; each guide mechanism is composed of a flexible guide structure and brackets which are axially arranged at the two ends of the flexible guide structure,and the flexible guide structure comprises a reed and a flexible guide unit which is of a hollow structure in a radial direction. Under a working state, a rotor axially moves to drive brackets in thetwo guide mechanisms to generate axial displacement, so that the elastic reeds in the two guide mechanisms generate deformation. Compared with the prior art, the precise positioning platform has theadvantages that the guide mechanisms are small in radial dimension, the platform is compact, light path transmission is facilitated, motion freedoms, in other directions except from the axial direction, of the voice coil motor are restrained, dual-end output is achieved, and the like.

Description

technical field [0001] The invention relates to the technical field of precision positioning platforms, in particular to a hollow one-dimensional precision positioning platform. Background technique [0002] The precision positioning platform has a very wide range of applications, such as in ultra-precision machining, optical imaging, biological cell manipulation, microelectronics integrated manufacturing and other fields. The voice coil motor has the characteristics of simple structure, high output linearity, fast response speed and easy control, and has gradually become the main driving device of the precision positioning platform. [0003] Since the stator and the mover of the voice coil motor are not directly connected, the output motion of the motor needs to be guided by a guiding mechanism. In traditional designs, rigid transmission components such as linear bearings or slide rails are mostly used. However, due to the inevitable gap, friction and wear in the transmiss...
