Automatic screening machine for magnetic reed switches

Abstract

The invention discloses an automatic screening machine for magnetic reed switches, comprising an AT (Automatic Transmission) tester, a material basket and a magnet cavity, wherein the material basket is used for the integral putting of the magnetic reed switches; a pair of permanent magnets opposite to each other with opposite magnetic poles is arranged in the vertical direction in the magnet cavity; the bottom of the magnet cavity is communicated with a vertical slide way on which an induction coil is sheathed; the tail end of the slide way is connected with the inlet of the AT tester; the longitudinal outlet of the AT tester is connected with a cylinder group; a separator with a plurality of hole sites is arranged at the bottom of the cylinder group and connected with a box at the hole sites through ingress pipes; and the material basket sucks the magnetic reed switches therein through a vacuum suction tube and sends the magnetic reed switches into the magnet cavity. Through the invention, the integral putting of the magnetic reed switches during the screening is realized and the magnetic reed switches are separated according to different AT values so that the automation level and the work efficiency are improved, the structure is simple and the operation is convenient.

Description

technical field [0001] The invention relates to a magnetic reed switch automatic screening machine, in particular to a magnetic reed switch automatic screening machine which can quickly check the AT value of the magnetic reed switch and automatically screen and separate the magnetic reed switch. Background technique [0002] The sensitivity of the reed switch is an important parameter of the reed switch. The sensitivity refers to the magnetic field strength that makes the contacts of the reed switch close, or the ampere-turns of the external excitation coil. There are three elements in selecting a reed switch, one is the current capacity of the contact, the other is the external dimension, and the third is the sensitivity. The measurement of the sensitivity of the reed switch usually involves the measurement of the AT value of the reed switch. The AT value refers to the It is the number of ampere turns of the external excitation coil, which is the product of the current when...

AI Technical Summary

Problems solved by technology

At present, after the reed switch is produced, it is sorted and screened according to its AT value. Since the reed switch is a fragile product, the traditional reed switch screening machine manually puts the reed switch into the AT test machine one by one. Then put them into different boxes according to the measured AT value. This operation is labor-intensive, poor in safety, and prone to errors.
