Magnetic induction character wheel counter

Abstract

The invention relates to the field of data identification in measurement technologies, and particularly relates to a magnetic induction character wheel counter. The magnetic induction character wheel counter comprises a character wheel group, a magnetic induction unit, wherein the character wheel group comprises more than two coaxially arranged character wheels, and the adjacent character wheels are connected through a carry gear; the character wheel group comprises at least one character wheel provided with a ferromagnetic substance; the ferromagnetic substance is arranged at a position, where at least one number is located, on the character wheel; the magnetic induction unit is in one-to-one correspondence with the character wheel provided with the ferromagnetic substance and is arranged on a circuit board, and the magnetic induction unit comprises a U-shaped magnetic block and a magnetic induction chip arranged in a notch of the magnetic block. The ferromagnetic substance rotating along with the character wheel causes a magnetic field of the magnetic block to change when approaching the corresponding magnetic block. The magnetic induction chip is used for inducing changes in the magnetic field and outputs counting pulses to the circuit board. by adopting the technical scheme provided by the invention, an automatic process with a higher degree can be realized, induction of the magnetic induction chip for changes in the magnetic field of the U-shaped magnetic block is more stable and more accurate at the same time, the stability of the counting device is increased, and the service life of the counting device is prolonged.

Description

Technical field [0001] The invention involves the field of data identification in measurement technology, especially a magnetic induction wheel counter. Background technique [0002] The word wheel counting device in existing technologies is mostly used to install magnetic materials on the word wheel, and the electronic pulse counting is performed through the cadre scruption.Such products have 2 disadvantages: 1. The pipe foot plastic surgery during welding of the cottage is easy to cause a slight leakage of the dry spring tube vacuum glass tube, and this micro leakage is not easy to find, which causes the use of micro -leaking dry scret tunnels.The measurement of the word wheel count is inaccurate after a period of time.2. Incorporation cannot perform the automation process directly during the plastic welding process, and artificial intervention is required, and the production efficiency is not high.
