Disclosed is a manufacturing system using a tray in the present invention. The manufacturing system according to the present invention comprises: a tray which has several maintaining units in which materials are accommodated respectively； a first recognition means which recognizes tray identification information； a material preparing unit which has a computer terminal for using the recognized tray identification information to display a tray image on a display； a working unit which has a working robot which picks up materials accommodated in the tray and performs manufacturing processes； a material supplying unit which is provided in one side of the working unit to locate the tray on a pickup place； a second recognition means which is installed in the working unit or in the material supplying unit and recognizes the tray identification information of the tray reached to the pickup place； and a control unit which controls the working robot according to the manufacturing process checked by the tray identification information recognized by the second recognition means. According to the present invention, a worker intuitively checks locations to accommodate materials while seeing a tray image displayed through a display, such that a work burden can be reduced, and the accuracy of material accommodation can be greatly improved. In addition, since materials can be arranged in the maintaining units of the tray, separate material arranging means is unnecessary. Moreover, a magazine having a complex structure for supplying materials like existing magazines is not necessary, thereby greatly reducing manufacturing costs of a device.본 발명은 트레이를 이용하는 제조 시스템을 개시한다. 본 발명에 따른 제조시스템은, 각각 재료가 수납되는 다수의 유지부를 구비하는 트레이와, 트레이 식별정보를 인식하는 제1 인식수단과, 인식된 트레이 식별정보를 이용하여 디스플레이에 트레이 이미지를 표시하는 컴퓨터단말을 구비하는 재료준비부； 트레이에 수납된 재료를 픽업하여 제조프로세스를 수행하는 작업로봇을 구비하는 작업부； 작업부의 일측에 구비되어 픽업위치에 트레이를 위치시키는 재료공급부； 상기 작업부 또는 상기 재료공급부에 설치되어 상기 픽업위치에 도달한 트레이의 트레이 식별정보를 인식하는 제2 인식수단； 상기 제2 인식수단에서 인식한 트레이 식별정보를 통해 확인되는 제
