Abstract

Humans were able to master the process of piercing objects through drilling holes as an advanced beading technique. There would be a great demand for beads and they appear more and more in human daily life. Many things are made from bead strings such as jewelry, furniture and house decoration. The beading process is usually done manually by hands of workers. The process takes a lot of effort and cost for labor. Therefore, this project is about building a simple device that helps to free the work effort and lower the labor cost. The bead strings machine has 3 main parts: frame, roller system and gear system. Beads go to roller system through the funnel on top. The gear system will deliver beads to final destination by using plastic elevator attached to the gear. The motor attached to the frame has two shafts, one uses for the motor the other uses for the gear. The material is made of stainless steel because of its high strength, high stiffness, good machinability, good formability and good corrosion resistance. The device is tested by using timer to determine the productivity. This project’s result is expected to be more efficient than the traditional ways. Production rate was over 150 beads per minute and the machine cost less than $400.
