In this paper, we introduce a fixer attaching robot system which is used to attach several fixers to a TV cabinet. It is necessary to automate the fixer attaching process for two reasons. One is that the process is very harmful because very strong ultraviolet rays are used in that process. The other is that the productivity and the overall quality of the end-product are determined by the fixer attaching process. We proposed 9 candidates for the robot system to be used in the fixer attaching process. Then we simulated cycle time for each of the 9 candidates with considering physical constraints. We also considered other aspects such as the easiness of implementation, possible interference with other mechanical structure, and cost etc. to choose one of the 9 candidates. We implemented the chosen robot system and adopted it in a TV manufacturing process.

In the TV manufacturing industry, a demand for chic design of TVs is increasing. As a reult of this trend in TV design, more curved surfaces in a TV cabinet are introduced, which enforces the use of fixers to combine a front cabinet with a TV main body. In this paper, we introduce a robot system for attaching various types of fixers to a TV cabinet. The developed system consists of three main blocks. The first one is the dispensing block, in which transferred cabinet is centered and UV adhesives are dispensed on the cabinet. The second one is the fixer attaching block, in which a cabinet is centered again and fixers are attached to pre-determined places on a cabinet by a robot with several end effectors. The last one is the UV hardening block, in which very strong ultraviolet rays are applied to the cabinet for attaching fixers tightly to the cabinet. The developed system is successfully adopted in a TV manufacturing process.
