Quartz crystal automatic screening machine

Abstract

A quartz crystal automatic screening machine is provided with a screening platform, an automatic feeding vibrating plate is arranged above the screening platform, and a screening mechanism is provided at the outlet of the automatic feeding vibrating plate, and the screening mechanism includes a downwardly inclined trough. The upper end of the trough is connected to the outlet of the automatic feeding vibrating plate, and the lower end of the trough is equipped with a quartz crystal gate, which has two upper and lower gates. The bottom of the gate is provided with a gate for the gate to lift, the screening platform is equipped with a gate lifting mechanism, the inner wall of the lower gate is equipped with a quartz crystal detection mechanism, and the screening platform below the gate is provided with a moving material box. The invention transports the detected quartz crystals to different storage boxes through the different lifting times of the upper and lower gate plates, which improves the screening speed and screening accuracy of the quartz crystals one by one, and the detection mechanism controls the gate through the control system. The lifting of the plate and the movement of the moving material box improve the screening accuracy.

Description

technical field [0001] The invention relates to a screening device, in particular to a quartz crystal automatic screening machine. Background technique [0002] As an important electronic material, quartz crystal is mainly used in some precision instruments and cutting-edge technology fields such as national defense. In order to adapt to the current increasingly fierce competition mechanism, wafer manufacturers have gradually increased their requirements for quartz crystals. Only relying on traditional detection methods to detect quartz crystals can no longer meet the needs of the market. [0003] Existing quartz crystal production enterprises, due to the large amount of quartz crystal processing, are prone to omission or misselection in the continuous screening process, resulting in slow screening speed, low screening accuracy, poor product reliability, and difficulty in meeting precision requirements. Instruments and other cutting-edge technology products have strict requ...

In order to adapt to the current increasingly fierce competition mechanism, wafer manufacturers have gradually increased their requirements for quartz crystals. Only relying on traditional detection methods to detect quartz crystals can no longer meet the needs of the vast market.

[0003] Existing quartz crystal production enterprises, due to the large amount of quartz crystal processing, are prone to omission or misselection in the continuous screening process, resulting in slow screening speed, low screening accuracy, poor product reliability, and difficulty in meeting precision requirements. Instruments and other cutting-edge technology products have strict requirements on quartz crystals
