Chip mounter placement head universal control system and control method thereof

Abstract

The invention discloses a chip mounter placement head universal control system and a control method of the chip mounter placement head universal control system. The chip mounter placement head universal control system is composed of an FPGA core processing module, an image collecting module, a video decoding module, a VGA driving module, a servo motor control module, an I / O port module, a communication module and an ADC module. An embedded universal solution that all the modules are integrated on one embedded board card is achieved. By means of the chip mounter placement head universal control system, the functions of image collection, image processing, image real-time displaying, placement head R-axis motor movement control and placement head placement process control in the placement process of the chip mounter placement head are achieved, image data collected by an image collection system do not need to be sent to chip mounter control software to be processed or displayed, the integration level and universality of the chip mounter placement head universal control system are improved, and complexity of the chip mounter control software and cost of the chip mounter placement head universal control system are reduced.

Description

technical field [0001] The present invention is an embedded system based on FPGA (Field Programmable Gate Array, Field Programmable Gate Array) as the core, and in particular relates to a general control system of a placement head of a placement machine and a controller thereof. Background technique [0002] The placement head is the core execution component of the placement machine, and it is a complex system that is closely combined with mechanical and electrical characteristics. Under the control of the control system, it accurately picks up components accurately and quickly, and automatically corrects the position through the vision system, and places the components accurately on the designated position. The development of the placement head is a sign of the progress of the placement machine. [0003] The realization of the control system of the placement head of the existing placement machine basically adopts the electrical system of the placement head built by connect...
