AI Technical Summary

Technical Problem

In wafer manufacturing, defective ingots flowing into the die bonding process reduce production efficiency. Existing technologies make it difficult to effectively screen and remove defective ingots with damaged appearance or missing markings.

Method used

A sorting device is designed, comprising a detection platform, first and second detection modules, a conveying device, and a cutting device. By detecting the appearance and marking characteristics of the crystal rods, defective crystal rods are screened out, and they are removed or cut by the conveying device.

Benefits of technology

This effectively prevents defective crystal rods from entering the next process, improves production efficiency, reduces material waste, and saves production costs.

Abstract

The application relates to a sorting device, which comprises a detection platform, a first detection module and a second detection module, and a first carrying device and a second carrying device. The detection platform is configured to form a first conveying channel for conveying a detected object. The first detection module is configured to form a detection station for detecting a first appearance feature of the detected object. The second detection module is configured to detect a second appearance feature and an identification feature of the detected object located in the first conveying channel. The first carrying device is configured to clamp the detected object and move the detected object from the detection station to the first conveying channel. The second carrying device is configured to carry the detected object away from the first conveying channel when the detection result of at least one of the first detection module and the second detection module does not meet a preset condition. The sorting device can screen out defective crystal rods with damaged appearance or lost identification from the detection platform, and the defective crystal rods can be removed through the second carrying device, so that the production efficiency is effectively improved.
