【摘要】：動力電池是電動汽車的關鍵部件，鋰離子動力電池逐步取代傳統(tǒng)的鉛酸電池和鎳氫電池成為動力電池發(fā)展的主要方向。隨著電動汽車市場份額的增大，鋰離子動力電池成為當今動力電池的研究熱點，帶動整個鋰電池設備產業(yè)的發(fā)展。 國內鋰電池設備行業(yè)起步晚，與國外產品相比有較大差距。極片分切機是疊片電芯成型方案中的主要設備之一，傳統(tǒng)分切機的效果不太理想，“毛刺問題”突出。 激光切割具有切割痕跡窄小、切割面質量好、切割效率高、無機械應力、噪聲污染小等特征。在本文中，我們將激光切割技術和嵌入式技術相結合，研制激光切片機，將激光應用于電芯制造工藝中。 本文首先分析了激光切片機系統(tǒng)的功能需求，提出了激光切片機的整體設計方案。以RTAI構建實時Linux操作系統(tǒng)，對系統(tǒng)采用層次化、模塊化思想進行劃分，在實時控制系統(tǒng)基礎上，，引入硬件抽象層（HAL，Hardware Abstraction Layer）機制，將各模塊以軟件構件的形式進行封裝。分析了人機界面模塊的開發(fā)，介紹了任務管理模塊、數據庫模塊、運動控制模塊以及軟PLC模塊的功能。系統(tǒng)以PC104和FPGA為核心構建硬件平臺，然后介紹脈沖發(fā)生器、編碼器、激光器等硬件模塊的電路設計。最后給出了激光切片機系統(tǒng)的實際應用效果及當前存在問題。

Lithium ion battery has gradually replaced the traditional lead-acid battery and Ni-MH battery as the main direction of the development of power battery. With the increase of electric vehicle market share, lithium ion power battery has become the research hotspot of power battery nowadays, and has driven the development of lithium battery equipment industry. Domestic lithium battery equipment industry started late, compared with foreign products there is a big gap. The pole slicing machine is one of the main equipments in the laminated electric core forming scheme. The effect of the traditional cutting machine is not ideal, and the "burr problem" is prominent. Laser cutting has the characteristics of narrow cutting trace, good cutting surface quality, high cutting efficiency, no mechanical stress, little noise pollution and so on. In this paper, we combine laser cutting technology with embedded technology to develop laser slicer, and apply laser to the manufacturing process of electric core. In this paper, the functional requirements of laser slicer system are analyzed, and the overall design scheme of laser slicer is put forward. RTAI is used to construct the real-time Abstraction operating system. The system is divided into layers and modularization. On the basis of the real-time control system, the hardware Abstraction layer mechanism is introduced, and each module is encapsulated in the form of software component. The development of man-machine interface module is analyzed, and the functions of task management module, database module, motion control module and soft PLC module are introduced. The hardware platform is constructed with PC104 and FPGA as the core. Then the circuit design of pulse generator, encoder, laser and other hardware modules is introduced. Finally, the practical application effect and existing problems of laser slicing machine system are given.
