【摘要】：随着电子行业的迅猛发展,印制电路板的需求量也在不断增加。在涉及到电路板的检测时,目前大多数企业采用人工方法进行检测,效率较低且检测过程中容易产生损毁。因此,有必要对特定的印制电路板进行分析,研究其自动进料及检测工艺以设计一套专用的电路板进料检测设备。本课题研究4G印制电路基板的自动化进料检测技术及其装备设计。首先,基于电路板的结构特点及电气特性,根据工序设定要求,设计了一款便于板料装卸的进料机。其次,对电路板检测过程中的动作要求进行分析,设计了一台自动检测的设备。最后,对插拔检测操作的模型进行简化并分析,研究了插拔过程中不同阶段所需要的插入力,并确定了影响参数;最终在实际样机上进行系统功能的试验。研究过程中,采用Solidworks2010对设备进行三维建模;采用ANSYS Workbench14.5对重要结构件进行有限元分析;采用三菱PLC搭建电路板自动进料控制系统;采用研祥工控机结合泓格运动控制卡构建电路板检测控制系统。在整体设计的过程中,涉及到方案设计、元器件的选型设计、整体尺寸框架的确定、材料的选择、结构建模、配件购买、电气系统搭建等过程,最终设计制造了一套印制电路板自动进料检测的专用设备。实验表明,插拔成功率达到96.1%。本课题提出了4G印制电路基板自动进料检测技术,提高了印制电路板生产的自动化程度。该成果将有利于解决印制电路板传统检测方法所带来的产品一致性差、生产效率低、人力成本高等问题,为实现电路板自动化生产提供了较好的参考价值和指导意义。
[Abstract]:With the rapid development of electronic industry, the demand of printed circuit board is increasing. When it comes to the detection of circuit boards, most enterprises use manual methods to detect, which is inefficient and prone to damage in the detection process. Therefore, it is necessary to analyze the specific printed circuit board and study its automatic feeding and testing technology in order to design a set of special circuit board feed detection equipment. In this paper, the automatic feed detection technology of 4G printed circuit substrate and its equipment design are studied. Firstly, based on the structural and electrical characteristics of the circuit board, a feeding machine is designed to facilitate the loading and unloading of sheet metal. Secondly, an automatic testing device is designed by analyzing the action requirement of the circuit board detection process. Finally, the model of plug detection operation is simplified and analyzed, the insertion force in different stages is studied, and the influence parameters are determined. Finally, the system function test is carried out on the actual prototype. In the research process, Solidworks2010 is used to model the equipment, ANSYS Workbench 14.5 is used to analyze the important structure, Mitsubishi PLC is used to set up the automatic feed control system of circuit board. The detection and control system of circuit board is constructed by using Yanxiang industrial control computer combined with Hongge motion control card. In the whole design process, it involves the project design, the type selection design of components, the determination of the overall dimension frame, the selection of materials, the structure modeling, the purchase of accessories, the building of electrical system, etc. Finally, a set of special equipment for automatic feed detection of printed circuit board is designed and manufactured. The experiment shows that the success rate of insertion is up to 96.1%. In this paper, the automatic feed detection technology of 4G printed circuit substrate is put forward, which improves the automation degree of printed circuit board production. The results will be helpful to solve the problems of poor product consistency, low production efficiency and high labor cost brought by the traditional testing methods of PCB, and will provide a better reference value and guiding significance for the realization of PCB automation production.
