Heat treatment of metals is an necessary process for obtaining properties required for metals. However, the heat treatment sector is labor intensive enough to be classified as an unwanted sector. In particular, in the case of quenching during the heat treatment, in order to select the defective product due to the collision caused by the collision between the products when the product is dropped in the oil tank during the quenching process, the labor is not concentrated on the heat treatment as the main process, It is a fact that it is put in. In this paper, in order to solve the labor - intensive nature, this paper designed and tested prototype products for the selection of defective products during the heat treatment process of the ball stud. The ball stud inspection device is divided into two parts, a ball stud supply device and an inspection device, and describes the concept design and prototype production contents. The performance of the prototype was evaluated by examining 1000 samples with 5 items. The manufactured ball stud inspection system will contribute to the relaxation of the avoidance phenomenon of the heat treatment industry and contribute to the efficiency and competitiveness of the work.
