Experimental investigation of the quality and productivity of high accuracy electrical component on sucking blowing process

The aim of this paper is to compare the manual and the automated processes of sucking and blowing of an electronic timer Omron series H3Y. The experimental data was taken from two types of machine, which are manually operated and automated machine. The result of the experiment is a comparison between productivity and the quality of the manual and automated processes. Productivity in the course of sucking and blowing show that automatic processes are capable of producing more quantity and stable product that is 810 pieces/day with production speeds of 6 seconds/product with two stages of sucking and blowing process performed on the 6-point blowing at once. The manual process is capable of producing 640 pieces/day with a product speed of 12.7 sec/product, which is divided into 2 phases with 5-point blowing, carried one by one manually. The quality of the results depends on several things, namely the ability to reduce particles of dust, noise, scratch and bend produced, and there is no abnormal noise when the product in shucking. The automated process can reduce dust particles up to 80%, compared to the manual process, which only reached 67%. The noise level during the process shows that the manual process has a higher noise level with a value of 75.1 to 91.8 dB(A) while automatic processes only 79.4 to 84.4 dB(A) which is measured from the operator stay point. Hence, manual process requires the operator to use earplug. As well as on both the process does not generate interference and functional characteristics, and does not produce a scratch or bend the product despite the friction during automated processes.
