Abstract
Description
Technical Field
[0001] This utility model belongs to the field of ophthalmic medical device technology, specifically an ophthalmic four-axis automatic platform. Background Technology
[0002] An optometry instrument examines the convergence of light after it enters the eye. Using emmetropia (normal vision) as a standard, it measures the difference in convergence and divergence between the tested eye and a normal eye. The optometry instrument has a built-in light source, usually an LED, which projects light onto the subject's pupil through a complex lens system. This light passes through the cornea and lens of the eye and focuses on the retina. Upon reaching the retina, some light is reflected back. The optometry instrument captures these reflected lights and analyzes their path changes. If the eye has a refractive error, the path of the reflected light will be deviated. The instrument has an automatic adjustment mechanism that adjusts its lens group according to the changes in reflected light to simulate the effect of different prescription glasses. By continuously adjusting until the path of the reflected light returns to normal (i.e., the light spot becomes the clearest), the instrument can calculate the required correction power for the subject's eye.
[0003] Currently, ophthalmic diagnostic and therapeutic devices have a very wide range of applications. However, in terms of equipment development, the traditional approach of developing multi-axis motion platforms with optical components on different platforms is still used. This approach results in low development efficiency, slow speed, and high manpower requirements. It also greatly increases the repetitive development process. Therefore, there is an urgent need for a universal, low-cost, ophthalmic four-axis automated platform device. Utility Model Content

[0010] The above technical solution involves using a second motor to drive a second lead screw to rotate, which in turn drives the Z-axis movable plate to move along the guide post, thereby achieving Z-axis movement.
[0011] In a preferred embodiment, the X-axis translation mechanism further includes a fixed plate, which is fixedly installed on the upper surface of the Z-axis movable plate.

A teleconverter is fixedly installed on the side of the X-axis slider away from the first cylinder.
[0012] The above technical solution uses the operation of the first cylinder to drive the X-axis slider to move along the first guide rod along the X-axis.
[0013] In a preferred embodiment, the forehead support adjustment mechanism further includes a vertical plate, which is fixedly installed on one side of the upper surface of the fixed base. A second cylinder is fixedly installed at the lower end of one side of the vertical plate. A forehead support slider is fixedly installed at the end of the output shaft of the second cylinder. A connecting rod is fixedly installed on the upper surface of the forehead support slider, and a forehead support is fixedly installed on the upper surface of the connecting rod.
[0014] The above technical solution uses the second cylinder to move the forehead support up and down, thereby achieving adjustment of the forehead support.
