sorting device

Abstract

The invention provides a classification device capable of accurately classifying a large number of electronic parts without misclassifying them. The sorting device (1) sorts and stores electronic components into corresponding storage parts among the plurality of storage parts (2A-2F) based on the classification level determined by the inspection device, and has: 2A~2F) a plurality of input ports (3A~3F) corresponding respectively; the moving mechanism (5) moves the input port member (3) based on the classification level determined by the inspection device to make the plurality of input ports (3A~3F) The corresponding input port in the middle moves to the input position of the electronic parts; a plurality of slideways (4A~4F) respectively guide the electronic parts to a plurality of storage parts (2A~2F), and the inlet sides are respectively fixed on the input port member (3) The outlet sides of the plurality of inlets (3A to 3F) are respectively located in the plurality of storage parts (2A to 2F) regardless of the movement position of the inlet member (3).

Description

technical field [0001] The present invention relates to a sorting device for sorting electronic components such as small semiconductors and storing them in a storage unit based on inspection results such as electrical characteristic inspection and appearance inspection. Background technique [0002] In electronic components including semiconductor devices such as mini mold transistors, a large number of electronic components are mass-produced using rectangular lead frames, and each electronic component is separated and shipped. In this case, after the electronic components are taken out from the lead frame, they are typically transported using a rotary transfer device consisting of a rotary table. After a series of treatments required at the time of delivery, the label is inserted into the carrier tape for packaging. [0003] Here, even if a large number of electronic components of one type are processed and manufactured by the same process and the same apparatus, considera...

AI Technical Summary

Problems solved by technology

[0009] In the sorting device described in the above-mentioned Patent Document 1, the swing pipe is swung according to the quality level of the electronic components after the quality inspection, and the lower end of the swing pipe is positioned at the position of any distribution port, thereby distributing. Therefore, Accurate sorting is not guaranteed without confirmation of passage of electronic parts at the dispense port

However, even if the sensor is configured to sense the passage of the electronic part at the dispensing port, if it is determined that the electronic part has passed due to sensor error sensing regardless of whether the electronic part has not passed, it will move to the next one. Classification process of electronic parts, resulting in misclassification

In addition, when the swing tube is moved at high speed, sometimes it is misclassified to the adjacent position instead of the original correct position
