【摘要】：隨著全球能源危機(jī)的加劇,LED因其具有綠色、環(huán)保、節(jié)能等特點(diǎn)而得到推廣。國(guó)家也推出了一系列政策來(lái)大力推動(dòng)LED產(chǎn)業(yè)的發(fā)展。LED封裝環(huán)節(jié)作為L(zhǎng)ED產(chǎn)業(yè)鏈中的重要一環(huán),其將直接影響LED的性能與質(zhì)量。通過(guò)調(diào)研發(fā)現(xiàn),目前LED封裝設(shè)備控制系統(tǒng)的自動(dòng)化程度并不高,而傳統(tǒng)的PC Based解決方案存在實(shí)現(xiàn)成本偏高、系統(tǒng)通用性不強(qiáng)等問題,為此本文設(shè)計(jì)了基于Zynq-7000 AP SoC平臺(tái)的LED封裝設(shè)備新型控制器,提出將圖像采集系統(tǒng)及運(yùn)動(dòng)控制系統(tǒng)集成到單片芯片的嵌入式解決方案,提高控制速度,滿足封裝設(shè)備的控制需求。本課題以Zedboard開發(fā)板為核心控制器件,配合自行設(shè)計(jì)的一塊功能擴(kuò)展板搭建了控制器研發(fā)初期的功能驗(yàn)證平臺(tái)。并為了滿足LED封裝設(shè)備對(duì)運(yùn)動(dòng)控制系統(tǒng)高速、高精度、低沖擊、可軌跡追蹤的性能需求,研究了基于非對(duì)稱S型加減速的速度規(guī)劃算法,以及基于雙層插補(bǔ)策略的軌跡跟蹤算法。其中雙層插補(bǔ)策略中以時(shí)間分割法做粗插補(bǔ)運(yùn)算,而以最小偏差法做精插補(bǔ)運(yùn)算。文中通過(guò)Matlab仿真驗(yàn)證了算法的正確性及可行性。并在此基礎(chǔ)上,利用PS端的高速運(yùn)算性能以及PL端的靈活可擴(kuò)展性,在Zynq平臺(tái)上實(shí)現(xiàn)了算法的移植和運(yùn)動(dòng)控制系統(tǒng)的構(gòu)建。并通過(guò)搭建實(shí)驗(yàn)平臺(tái),驗(yàn)證了新型控制器的實(shí)際運(yùn)行效果。另外,為了滿足新型控制器對(duì)圖像采集系統(tǒng)的需求,通過(guò)分析Zynq平臺(tái)內(nèi)部互聯(lián)資源,設(shè)計(jì)了圖像數(shù)據(jù)采集模塊、圖像存儲(chǔ)模塊以及圖像顯示模塊。使得新型控制成為具備圖像采集能力和運(yùn)動(dòng)控制能力的通用平臺(tái)。根據(jù)應(yīng)用場(chǎng)景的不同,只需往控制器內(nèi)部注入不同的圖像算法,便可實(shí)現(xiàn)控制器的復(fù)用。本課題的新型控制器的研究,可為我國(guó)對(duì)LED封裝設(shè)備高性能控制系統(tǒng)的研究提供參考,對(duì)于提高我國(guó)LED生產(chǎn)線的國(guó)產(chǎn)化和自動(dòng)化水平、推動(dòng)我國(guó)LED封裝設(shè)備產(chǎn)業(yè)的發(fā)展具有一定的現(xiàn)實(shí)意義和應(yīng)用前景。
[Abstract]:With the aggravation of global energy crisis, LED has been popularized because of its green, environmental protection, energy saving and so on. The government has also introduced a series of policies to promote the development of LED industry. As an important part of the LED industry chain, the packaging link of LED will directly affect the performance and quality of LED. Through investigation, it is found that the automation degree of LED packaging equipment control system is not high, but the traditional PC Based solution has some problems, such as high cost of realization and weak generality of the system. In this paper, a new controller of LED packaging equipment based on Zynq-7000 AP SoC platform is designed, and the embedded solution of integrating image acquisition system and motion control system into a single chip is proposed to improve the control speed and meet the control requirements of packaging equipment. In this paper, the Zedboard development board is taken as the core controller, and a functional extension board designed by ourselves is used to build a functional verification platform for the initial development of the controller. In order to meet the requirement of high speed, high precision, low impact and traceability of motion control system for LED packaging equipment, a speed planning algorithm based on asymmetric S-type acceleration and deceleration is studied. And track tracking algorithm based on double interpolation strategy. In the bilevel interpolation strategy, the time division method is used for rough interpolation and the minimum deviation method for fine interpolation. The correctness and feasibility of the algorithm are verified by Matlab simulation. On this basis, the high speed computing performance of PS terminal and the flexible expansibility of PL terminal are used to realize the transplantation of algorithm and the construction of motion control system on Zynq platform. The actual operation effect of the new controller is verified by setting up the experimental platform. In addition, in order to meet the demand of the new controller for image acquisition system, the image data acquisition module, the image storage module and the image display module are designed by analyzing the internal interconnected resources of the Zynq platform. So that the new control has become a general platform with the ability of image acquisition and motion control. According to the different application scenarios, the controller can be multiplexed by injecting different image algorithms into the controller. The research of the new controller in this subject can provide reference for the research of the high performance control system of LED packaging equipment in our country, and can improve the localization and automation level of the LED production line in our country. To promote the development of LED packaging equipment industry in China has certain practical significance and application prospect.
