Abstract

The invention relates to a vertical high-speed high-accuracy direct-driving mechanism. The mechanism comprises a vertically-placed base, vertically-placed sliding rails on the base, a primary linear motor and a secondary linear motor. The primary linear motor is installed on the base. The secondary linear motor is connected to a movable carrying plate, on which a sliding block is arranged. The sliding block is clamped on the sliding rails and move along the sliding rails. The primary linear motor and the secondary linear motor are arranged oppositely. The movable carrying plate is provided with a reading head. The base is further provided with a grating ruler used for sensing changes of the position of the reading head. The vertical high-speed high-accuracy direct-driving mechanism has following beneficial effects: by adoption of direct-driving technology of linear motors, extremely high acceleration and deceleration speed and motion speed are achieved; mechanical abrasion and opposite clearance are avoided; non-contact driving technology is utilized so that long service lifetime is realized; the base is made by large damping material so that value of amplitude for harmonic response of a lower-order mode is inhibited and vibration of the high-order mode is overcome; good dynamic response attribute is obtained; and by adoption of high-resolution position feedback device, full closed-loop control is achieved and the repeated accuracy is higher.

Description

technical field [0001] The invention relates to the field of automation equipment, in particular to a high-speed and high-precision direct drive mechanism in the vertical direction. Background technique [0002] With the development of economy and technology, automation equipment is more and more widely used in industrial production. In the vertical drive mechanism, the traditional way is mechanical transmission, and the traditional servo motor drives the rotating parts to move. The mismatch between speed and inertia has an impact on the movement process. Due to the existence of rotating parts, it needs to be lubricated. At the same time, its movement speed is slow, which will cause mechanical wear and backlash during the movement process, and vibration of the overall mechanism, shortening service life of the mechanism. [0003] Therefore, it is necessary to provide a high-speed and high-precision direct drive mechanism in the vertical direction to solve the above problems....
