Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to an automatic labeling machine for semiconductor wafers. Background Technology

[0002] In existing technologies, a wafer refers to a silicon chip made from silicon semiconductor integrated circuits. Because of its circular shape, it is called a wafer. Wafers are the carriers used to produce integrated circuits. Generally speaking, a wafer refers to a single-crystal silicon wafer. Single-crystal wafers are made from ordinary silicon sand, which undergoes a series of processes including dissolution, purification, and distillation to support single-crystal silicon rods. After polishing and slicing, the single-crystal silicon rods become wafers. A wafer disk serves as the carrier for the wafer. After the wafer is mounted on the wafer disk, a label corresponding to the wafer needs to be affixed to the wafer disk to accurately identify and manage the wafer during subsequent processing, inspection, and tracking. Currently, labeling on wafer disks is mostly done manually. Manual labeling is prone to errors, has low efficiency, and the labeling position accuracy is difficult to control, leading to low yield rates.

[0031] Working principle: When labeling wafer disks is required, several wafer disks to be labeled are placed side-by-side at intervals in the loading box 2 via a placement chute.

The output end of the labeling cylinder 15 extends, and the labeling nozzle 16 affixes the label to the wafer disk. The output end of the labeling cylinder 15 retracts, thus completing the labeling operation. During the labeling process, the detection camera 21 detects the labeling on the wafer disk. After the labeling is completed, the vacuum nozzle 9 stops working, and the loading robot 3 picks up the labeled wafer disk and moves it to the loading box 2 under the action of the moving component. The labeled wafer disk is placed back into the original placement groove to realize the unloading operation. Then, the electric lifting tray descends one level, and the loading robot 3 picks up the upper wafer disk of the labeled wafer disk to perform the next loading and labeling operation.
