Abstract
Description
Technical Field
[0001] This invention relates to the field of three-axis control equipment technology, and particularly to a three-axis servo control mechanism. Background Technology
[0002] With the development of industrial automation, three-axis motion platforms are widely used in various fields. Common three-axis mechanisms typically use three independent linear modules or servo motors for drive, and transmit power through ball screws or synchronous belts to perform positioning in the X, Y, and Z directions.
[0003] However, existing technologies have the following shortcomings: First, they are complex and bulky. The independent stacking of the three axes (e.g., the Z-axis is mounted on the Y-axis slide, and the Y-axis is mounted on the X-axis slide) results in a large load inertia on the top Z-axis, affecting dynamic performance. The overall structure is also tall and occupies a lot of space. Second, they lack precision and rigidity. Traditional serial structures suffer from error accumulation. The positioning accuracy of the end (Z-axis) is affected by the errors of all the preceding axes (X and Y axes). At the same time, the long chain transmission structure reduces the system rigidity and is prone to vibration. Third, they have slow dynamic response. Due to the large mass of the moving parts, especially in high-speed reciprocating motion, acceleration and deceleration performance are limited, making it difficult to meet the requirements of high-frequency and high-precision operations. Fourth, they have heat dissipation and interference problems. The centralized arrangement of servo motors and drivers may lead to local temperature rise, affecting accuracy. The management of cables and air pipes in complex motion is difficult and prone to interference or wear. Summary of the Invention
