【摘要】：扬声器在汽车、通信、交通、运输等领域的应用日益广泛。在其生产加工环节中,分层装箱是一道重要的工序。目前行业内普遍采用的人工装箱方式可能发生漏装缺失,造成严重后果。如何将装箱过程中的扬声器缺失检测自动化成为行业内的广泛需求。本课题针对人工分三层装箱的过程,利用机器视觉代替人眼视觉对分层装箱过程中的扬声器进行图像检测,研发了扬声器缺失自动检测系统。同时对扬声器分层装箱机器视觉的检测算法进行了研究,总结出一种适用于扬声器缺失的检测方法,并对自动检测装置的工作原理、硬件系统的结构设计和运动控制系统的设计做了介绍与分析。通过实验验证了所设计自动检测装置的合理性,能够实现对分层装箱的扬声器的缺失检测。针对扬声器分层装箱后在封箱前必须在顶层扬声器上方放置一块硬纸板,以保护扬声器在运输过程中不被损坏。本文还设计出一套自动出纸板机构,确保装箱工艺过程的完整性。本论文研究的主要内容包括:(1)针对扬声器分三层人工装箱过程中的漏装缺失,设计了机器视觉自动检测系统。(2)根据扬声器分层装箱的特点,提出一种基于图像选定区域特征实现装箱层自动检测的方法,同时,基于当前层每一个子区域的平均灰度实现扬声器的缺失检测,并通过相应的实验验证了该方法的可行性。(3)设计了一套基于三层扬声器装箱前自动覆盖纸板的运动机构,其中包括升降平台,推杆机构和吸盘套装的设计。(4)设计了缺失检测系统的运动控制部分,实现了步进电机的运动控制与电磁阀的协同动作。(5)通过实验验证了检测方法及系统的可行性。
[Abstract]:Loudspeakers are widely used in automobile, communication, transportation and other fields. In its production and processing, stratified packing is an important process. At present, the commonly used manual packing in the industry may be missing, causing serious consequences. How to automate the detection of loudspeakers in the packing process has become a widespread demand in the industry. Aiming at the process of manual three-layer packing, this paper uses machine vision instead of human vision to detect the image of loudspeakers in the process of stratified packing, and develops an automatic detection system for loudspeaker deficiency. At the same time, the detection algorithm of loudspeaker layered packing machine vision is studied, a detection method suitable for speaker missing is summarized, and the working principle of automatic detection device is also discussed. The structure design of hardware system and the design of motion control system are introduced and analyzed. The rationality of the designed automatic detection device is verified by experiments, and the missing detection of the loudspeaker with stratified packing can be realized. A piece of cardboard must be placed above the top loudspeaker to protect the speaker from damage during transportation. This paper also designed a set of automatic paperboard mechanism to ensure the integrity of the packing process. The main contents of this thesis are as follows: (1) the machine vision automatic detection system is designed for the missing of the loudspeaker in the process of three layers manual packing. (2) according to the characteristics of the loudspeaker stratified packing, A method for automatic detection of packing layer based on the feature of selected region of image is proposed. At the same time, based on the average gray level of each sub-region of the current layer, the loss detection of loudspeaker is realized. The feasibility of the method is verified by corresponding experiments. (3) A set of motion mechanism based on three-layer loudspeaker packing is designed, which includes lifting platform. (4) the motion control part of the missing detection system is designed to realize the motion control of the stepping motor and the cooperative action of the solenoid valve. (5) the feasibility of the detection method and the system is verified by experiments.
