Abstract

The invention relates to a buzzer test separator, belonging to the manufacturing field of electronic component test equipment. The separator comprises a rack, three groups of feeding boxes, a rotatable feeding arm, a U-shaped locating slot, a guide rail, test needles, a waste cabin, a qualified product cabin, a discharging hopper and a console, wherein the rotatable feeding arm with rotation amplitude of 0-90 degrees is provided with a material absorbing head to facilitate the absorption and delivery of a buzzer; the U-shaped locating slot with functions of vertical blanking and precise location can reciprocate along the guide rail below the material absorbing head and the test needles; the feeding box is a hollow cylindrical box with a gap, and three groups of feeding boxes work alternatively with high efficiency; the test needles arranged horizontally are used for vertical test with higher test accuracy than horizontal test; and the flexible discharging hopper is controlled by a discharging cylinder. The invention has the advantages of simple structure, accurate discharging and high reliability and practicability.

Description

technical field [0001] The invention relates to the field of manufacturing electronic component testing equipment, in particular to a testing and sorting machine for piezoelectric ceramic buzzer chips. Background technique [0002] The piezoelectric ceramic buzzer is a sounding element composed of a piezoelectric ceramic sheet and a metal substrate such as a copper sheet. It has the characteristics of thin thickness, light weight, clear pronunciation, anti-electromagnetic interference, and low power consumption; due to its non-contact Point, so no noise, high reliability. Widely used in various electroacoustic occasions, such as communication products, industrial instruments, household appliances and alarms: such as electronic clocks, car speakers, audio, communications, remote sensing, calculators, electronic toys and other products. [0003] At present, the testing and sorting work in the production process of piezoelectric ceramic buzzers is mainly performed manually, wh...
