In this study, the product design technology to facilitate the assembly automation is developed. First, checkistis are developed to analyse weakpoints which make assembly automation difficult. The weakpoints of assembly automation can be redesigned by using design rules for assemblability which are systematized in this research. In addition, the assemblability of product can be evaluated qualitatively with the new developed assembly evaluation method. This evaluation method is performed in the respect of the component parts, the assembly method and the assembly motion.

In this study, an automation assembly jig for the automation assembly process for the ventilation grille that is used in the interior of a car Is developed. As the method that can do the automation assembly for the ventilation grille, a simple jig and air cylinder have been applied. And a solenoid valve, a filter regulator, and on-off switch have been used in controlling the system. Moreover, the timer is attached to the equipment so that a worker may control the assembly time, as fitting the quantity on demand of production. Actually with executing the assembly test productivity and performance of assembly have been verified. In case of the automation assembly work for a ventilation grille is compared to the manual work. The optimum working speed has been identified to make the process twice or three times better.

This paper deals with the evaluation methods for flexible automated assembly systems based on characteristics of automation and flexibility. In this study, the degrees of automation and flexibility are calculated quantitatively as the means of evaluating assembly systems. The degree of automation is grasped wheter the detailed assembly flexibility can be calculated indirectly14 by the estimation of cost and time which are caused to adapt the changed environment of the assembly system. As a case study, an assembly system is evaluated for showing the procedures of the developed method.

Construction automation is yet to be improved since construction site still faces a lot of high risks and difficulties. This research focuses on applying robotic beam assembly system in place of construction workers. This system consists of CF (Construction Factory) structure to provide adequate working environment to robot automation. The CF structure not only gives automation environment for a robot but also houses the equipments to protect from outside effects. The robotic beam assembly system also consists of robotic bolting system and robot transport mechanism. It utilizes various tools to insert and join the bolts and nuts. Visual servoing helps precise robot motion by sensing bolt hole and tail of the bolt. ITA system helps non skilled workers to easily perform the assembly work with the robot system. The robot transport mechanism includes sliding rail and cross-wired lift. It carries the robot to a desired position for assembly work.

Implementing flexible production systems in domestic and foreign automotive design parts assembly has increased demand for automation and power reduction. Consequently, transition to a hybrid production method is observed where multiple vehicles are assembled in a single assembly line. Multiple robots, 3D vision sensors, mounting positions, and correction software have complex configurations in the automotive glass mounting system. Hence, automation is required owing to significant difficulty in the assembly process of automobile parts. This study presents a primer lighting and inspection algorithm that is robust to the assembly environment of real automotive design parts using high power 'ㄷ'-shaped LED inclined lighting. Furthermore, a 2D camera was developed in the primer coating inspection system-the core technology of the glass mounting system. A primer application demo line applicable to the actual automobile production line was established using the proposed high power lighting and algorithm. Furthermore, application inspection performance was verified using this demo system. Experimental results verified that the performance of the proposed system exceeded the level required to satisfy the automobile requirements.

Welding automation in shipbuilding process, especially in the assembly line is considered to be a difficult job because welding part is too huge , various and unstructured for a welding robot to weld the whole part automatically. We developed an automatic welding robot to improve those difficult process. This paper show how to systematically operate the integrated automation system which consists of several robots. We introduce our software and system integration method. Specially we focus that network communication and operating process. The developed system visualizes the operation environment using Open Inventor and communicates with the entire system via TCP/IP and FTP.

This paper deals with the automation techniques of ship assembly drawing generation, which help the designer to reduce the man-hour for completing the drawings, and improve the quality of the drawing for the given time. The automation techniques are necessary for the reasons of economical efficiency and improve communication between the designers and shop-makers. The overlap-avoidance algorithm of this paper maximizes the readability of the drawings using the optimization techniques and the heuristic rules, especially for the ship assembly field.

An automation process of filter unit is presented for the application of the assembling procedure and dry furnace work. By that automation procedure, it is expected to enhance working environment such as reducing laboring load, harmful gas, and burning scald. Furthermore, this automation process also minimizes via standardization of manufacturing process so that it may increase productivity and reliability. An automation process of filter unit is presented for the application of the assembling procedure and dry furnace work. Filter automation process also gives a good quality and productivity by simplifying to only one line from the complicated process such as filter cutting$\rightarrow$ adhering$\rightarrow$fabricating in a very small space. It is found that a new conceptual design of dry furnace shows the better quality like uniform heat distribution compared to the conventional design. It is also found that the present design gives a better working environment by adding cooling system.

본 논문은 PCB 생산 자동화를 위한 데이터 변환 시스템을 구현한다. CAD로 설계한 데이터는 PCB 생산라인과의 데이터 호환을 이루지 못하기 때문에 데이터 호환을 갖는 자동화 시스템이 필요하다. 본 논문에서는 PCB 생산 자동화를 위한 PCB 부품 정보를 분석하고 IC 부품 정보를 DB로 구축한다. CAD 설계자의 Human error 검출 알고리즘을 개발하고, PCB 생산 라인에 적합한 데이터로 변환하는 알고리즘을 개발한다. PCB 생산라인의 부품의 정보 추가, 수정하기 위한 데이터 변환 인터페이스를 설계 및 구현한다. 기존의 수작업 공정을 자동화함으로서 처리속도를 대폭 개선하였으며, 신뢰성 있는 칙적화된 데이터로 PCB 생산 자동화에 일조를 할 수 있다.
