| 中文摘要 | 本文设计了一套太阳能电池栅线喷印设备的控制系统，控制系统按功能化分为数据通信系统、运动控制系统和喷印控制系统。数据通信系统包括USB通信模块和命令解析模块。USB通信模块利用FPGA控制专用芯片与上位机通信，此过程中使用了乒乓操作技术来保证数据流的不间断传输。命令解析模块将上位机发送的数据流进行解释，提取命令信息和数据信息并发送到相应的驱动模块。运动控制系统包括位置检测模块，电机控制模块和真空吸附系统。位置检测模块将四分频后的光栅反馈信号作为伺服电机的位置反馈，提高控制精度。电机控制模块接收命令解析模块的信息完成对伺服驱动器的设置并发送特定的驱动信号。真空吸附系统用于喷印过程中固定硅片，在线固化系统用于控制硅片上墨滴中溶剂合适的挥发速度，进而保证栅线的良好形貌。喷印控制系统包括喷头控制系统、供墨系统和在线固化系统。喷头控制系统中，系统接收命令解析模块的信息并按要求时序要求发送驱动信号，完成纳米银墨水的喷射，借助喷头内置加热电阻和热敏电阻，以FPGA的设定信号作为输入，利用热敏电阻的采样作为反馈对加热电阻构成全闭环控制。供墨系统保证喷印过程中墨水的持续供应并且不出现墨水渗漏，真空吸附系统用于喷印过程中固定硅片。在线固化系统用于控制硅片表面墨滴中溶剂合适的挥发速度，进而保证栅线的良好形貌。最后，针对栅线的喷印，对控制系统进行了整体测试。本文从液滴间距、在线固化温度、重复喷印次数三个方面设计了一系列实验，并对实验结果进行了比较分析，为进一步的系统优化打下基础。 |
| 英文摘要 | This paper designed a set of control system to manufacture grids. In terms of function, master control system is divided into data communication system, motion control system and spray control system. Data communication system includes USB communication module and command parsing module. USB communication module uses FPGA program control special communication chip to communicate with upper computer. During this process, ping-pong operation is utilized to ensure continuous transmission of data. Command parsing module extracts command information and data information from the data coming from upper computer and then sent them respectively to the corresponding driver modules. Motion control system includes position detection module, motor control module and vacuum adsorption system. Position detection module use quadruplicated grating feedback as servo motor position feedback signal to improve control accuracy. Motor control module receives the information from command parsing module to set servo drive and send the specific driving wave. Vacuum adsorption system is used to fixed silicon slices Spray control system include nozzle control system, ink supply system and vacuum adsorption system. Nozzle control system receives the information coming from command parsing module and send wave as required to spray nano-silver ink. At the same time, the fully closed loop take use of the FPGA signal as the input signal, sampling of thermistor as feedback to control the heating resistance. Ink supply system ensures continuous ink supply and the ink never oozing from nozzles during spraying. Vacuum adsorption system is used to fixed silicon slices. On-line curing system is used to control the solvent of the drops on silicon slices in suitable volatilization rate, thus to ensure good morphology of grid lines. At last, in view of the grids spraying, control system is overall tested. A series of experiments are designed from three aspects: distance of neighboring droplets, on-line curing temperature and different printing times. Then, the results are compared and analysed which lays the foundation for further system optimization. |
