Description

Technical Field

[0001] This utility model relates to the field of mobile platform technology, and in particular to a dual-guided high-stability Z-axis mobile platform. Background Technology

[0002] A Z-axis moving platform is a device used to adjust height. The common method is to use a lead screw and lead screw nut to move the lifting plate of the Z-axis moving platform up and down. To maintain the stability of the lifting plate's movement, a set of guide structures is used. However, in practical applications, even a set of guide structures can easily cause the lifting plate to sway during and after lifting. This stability cannot meet the requirements of high-precision applications.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

This allows the lifting plate to be supported by both the first and second lifting vertical plates simultaneously, thereby minimizing the swaying of the lifting plate during the lifting process and improving the stability of the lifting plate after lifting, thus meeting the needs of high-precision application scenarios.

[0007] Furthermore, the first guiding mechanism is a cross roller guide rail; the two V-shaped raceway guide rails of the cross roller guide rail are respectively installed on the fixed vertical plate and the first lifting vertical plate; the second guiding mechanism includes: a fixed guide rail installed on the fixed vertical plate and a slider connected to the second lifting vertical plate; the slider cooperates with the fixed guide rail.

[0008] Furthermore, there are two first guiding mechanisms, with the ball screw positioned between them; there is one fixed guide rail, positioned at the center of the fixed vertical plate; the two first guiding mechanisms and the fixed guide rail are arranged in a triangular pattern, preferably an isosceles triangle. This triangular arrangement, due to the stability of the triangle, ensures more stable lifting of the lifting plate, and the lifting plate maintains excellent stability even after lifting is complete.

[0009] Furthermore, the two V-shaped roller guides installed on the fixed vertical plate are positioned between the two V-shaped roller guides installed on the first lifting vertical plate; or, the two V-shaped roller guides installed on the first lifting vertical plate are positioned between the two V-shaped roller guides installed on the fixed vertical plate.

[0010] Furthermore, the driving device includes: a motor and a power transmission device, wherein the output shaft of the motor drives a ball screw through the power transmission device.

[0011] Furthermore, the power transmission device includes: a first pulley connected to the output shaft of the motor, a second pulley connected to the ball screw, and a power transmission belt fitted on the first pulley and the second pulley.

[0012] Furthermore, the base plate is provided with a hollow groove, and the power transmission device is set in the hollow groove to make full use of the space.

[0013] Furthermore, the dual-guided high-stability Z-axis moving platform also includes: a bracket mounted on the base plate, several sensors mounted on the bracket, and a sensing plate mounted on the first or second lifting vertical plate, wherein the movement range of the sensing plate extends through the sensing range of the sensor. The sensor is an optocoupler sensor, and all the sensors are mounted on a single circuit board.

[0014] Furthermore, the dual-guided high-stability Z-axis moving platform also includes a cover mounted on the fixed vertical plate, the cover covering the second guide mechanism.

[0015] Furthermore, the first lifting vertical plate includes a side plate, which blocks the first guide mechanism.

[0016] By adopting the above solution, this utility model provides a dual-guided high-stability Z-axis moving platform. By setting a first lifting vertical plate and a second lifting vertical plate on both sides of the fixed vertical plate, the first lifting vertical plate is connected to the fixed vertical plate through the first guide mechanism, and the second lifting vertical plate is connected to the fixed vertical plate through the second guide mechanism. This allows the lifting plate to be supported by both the first and second lifting vertical plates simultaneously, thereby minimizing the shaking of the lifting plate during the lifting process and improving the stability of the lifting plate after lifting, thus meeting the needs of high-precision application scenarios.
