Developed of Automotive Bolt Supply and Automatic Quantity Feeder for Productivity Improvement

The existing bolt quantity detection method is inconvenient for the operator to use in the field because the bolts are placed on the plate in order to grasp the total quantity and the thread is inserted and aligned in the holes. In this study, we developed a device that automatically detects the quantity of bolts by detecting the bolts to improve the convenience and assembly speed of workers. The objective of this study is to apply the optimum bolt quantity detector to the field by analysis after laboratory experiment using the designed bolt quantity detector. Experimental design has 81 experimental specimens of 3, 5, 7 in diameter and 5, 7, 10 mm in length, and 10, 15, 20, 25, 30, 35, 40, 50° of the angle of the alignment part. Each experimental specimen was measured 100 times and then the mean value was applied to find the optimum angle. After 100 measurements of the diameter and length of a bolt, the number of repetition was the lowest for the average value when the bolt diameter was 5. In the development of machine bolt quantity detector, the length was more important than the diameter of the bolt.
