Abstract

The invention discloses a two-axle planar motion control card oriented to a full-automatic surface mount system and a two-axle planar motion control method, relates to the field of industrial motion control and stereometry, and aims to solve the problems of low transmission speed, low reliability and low accuracy in the conventional full-automatic surface mount system as well as the problem that the motion state of a controlled device cannot be reflected in real time by means of the conventional planar motion control method. The two-axle planar motion control card comprises a bus interface circuit, a CPLD (Complex Programmable Logic Device) module, a DSP (Digital Signal Processor) module, an SRAM (Static Random Access Memory) cache module and a lower layer interface circuit, wherein the SRAM cache module is used for supporting high-capacity data storage. In an internal software program of the DSP module, a synchronization algorithm and a speed planning algorithm are adopted. By adopting the synchronization algorithm, high synchronism of two coaxial motors is realized, and errors of the two-axle planar motion control card are up to a micron order. By adopting the speed planning algorithm, the motors run smoothly, act quickly, and are more stable and high in reliability when not running. The two-axle planar motion control card is suitable for surface mount machines, insertion-mount machines and similar products.

Description

technical field [0001] The invention relates to the fields of industrial motion control and plane surveying and mapping. Background technique [0002] Fully automatic surface mount system is a device that uses surface mount technology to complete the task of mounting components on PCB boards. It integrates advanced technologies in multiple fields such as automatic control, mechanical design and manufacturing, image recognition, and digital signal processing. Part of the organic whole has high requirements for performance indicators such as speed and reliability of motion algorithm control, signal processing and transmission. Therefore, the fully automatic placement system has strict requirements on its core motion control card. At present, the motion control card design that cannot take into account both high speed and high reliability is the main problem in the existing technology, and it is also one of the important bottlenecks restricting the development of domestic surf...
