Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a semiconductor device such as an integrated circuit, a memory circuit or various irregularly shaped parts (for example, a connector, a switch, a transmitter), various electronic equipments or a relatively small precision machine assembly for precision machine assembly The present invention relates to a tray for transporting precision parts suitable for holding individual parts (collectively referred to as “IC chips”) individually and carrying them into an automatic assembly machine or the like.

[0002]

2. Description of the Related Art In recent years, most of the main circuit components have tended to be made into chips in order to improve the operational reliability and assembly efficiency of electronic equipment. Therefore, in order to supply IC chips to various intermediate processing lines, final assembly lines, and the like, a relatively large-sized transport container in which recesses for accommodating chips are arranged in a plurality of rows and columns is used. In such a large container, chips are individually transferred to the processing or assembly line by a robot hand or the like arranged in the vicinity of one side edge of the transfer line, but the other side edge of the transfer line is used. The robot hand has to reciprocate over a long distance when taking out the IC chip in a portion close to the container from the container. This increases the waiting time on the processing line side, which is not only a negative factor for efficiency improvement, but also the gripping position must be changed every time, so if there is a failure to grab, chip damage or processing line confusion may occur. There is. In order to avoid such an adverse effect, the position control of the robot hand must be performed with high precision, and the control cost also increases.

[0003]

SUMMARY OF THE INVENTION Therefore, according to the present invention, trays that can be connected in a chain are compactly formed by an integrally molded product to facilitate the operation by a robot hand on the line and to simply store the IC chips. It can be securely held in the tray by a simple operation of pushing it into the arm, and the nail of the robot hand can be bitten from any of the front, back, left and right of the IC chip to improve workability. Its main purpose is to provide toner.
