Spreading type feeding device for quartz wafers

Abstract

The invention discloses a spreading type feeding device for quartz wafers. The spreading type feeding device comprises a supporting device and a feeding device body, wherein the feeding device body isinstalled at the upper end of the supporting device; a feeding outlet is formed in the side face of a material disc; and a material baffle is installed on the side face of an inner cavity of the feeding outlet. When materials vibrate under the vibration of a vibration source and output vibration energy with the proper frequency and amplitude to drive the material disc to achieve mechanical resonance, the quartz wafers in the disc slowly do linear movement towards an outlet of the material disc and are evenly spread to a target area through the feeding outlet. Under the vibration of the vibration source, a movable plate installed in an inner cavity of the material baffle does slight reciprocating oblique movement, and a rubber head on the side face of the movable plate can prevent the multiple materials from being overlapped and blocking the feeding outlet. A ratchet wheel is installed on the front face of a lifting device, a gear is installed on the back face of the ratchet wheel, andthe gear is in engaged connection with dense teeth. When the ratchet wheel is rotated, the gear drives the dense teeth so that a lifting table can do lifting movement, and the adaptability of the feeding device is higher.

Description

technical field [0001] The invention relates to the technical field of quartz wafer detection, in particular to a spreading type feeding device for quartz wafers. Background technique [0002] Quartz crystal oscillator is a resonant device made by using the piezoelectric effect of quartz crystal. Its basic composition is roughly as follows: cut a thin slice from a quartz crystal at a certain azimuth angle, and coat silver on its two corresponding surfaces. As an electrode, a lead wire is welded on each electrode and connected to the pin, and a package shell is added to form a quartz crystal resonator, which is referred to as a quartz crystal or crystal or crystal oscillator. Its products are generally packaged in a metal shell, and there are also Adopting glass shell, ceramic or plastic package, quartz crystal oscillator is a high-precision and high-stability oscillator, which is widely used in various oscillating circuits such as color TVs, computers, remote controls, and f...

AI Technical Summary

Problems solved by technology

[0003] The existing publication number CN201822118883.2 includes a material tray, a feeding outlet and a vibration source. The material vibrates slowly at the vibration source to the feeding outlet. It is difficult to operate the material when picking up the material from the detection equipment, and the feeding device cannot be adjusted up and down greatly, which greatly limits the scope of use of the feeding material
