A Position Detection Magnetic Sensor for Automatic Control

Abstract

A position detection magnetic sensor for automatic control, relating to the technical field of magnetic switches, comprising a hollow plastic box (1). A vertical separator (11) is provided in an inner cavity of the plastic box (1), and a conductive post (2) is laterally provided through the vertical separator (11). An action sheet (3) is provided in the inner cavity of the plastic box (1) on the right side of the vertical separator (11); a magnetic ring (4) is sleeved over the left end of the action sheet (3); and the right end of the conductive post (2) is provided through the magnetic ring (4) and is arranged in correspondence to the action sheet (3). A conductive sheet (22) is provided on the left end of the conductive post (2), and the conductive sheet (22) and the action sheet (3) are respectively connected to a lead (19) on the right side wall panel of the plastic box (1). The periphery of the magnetic ring (4) has a single polarity, and inductive driving mating of attraction and repulsion can be realized without the need for selecting the polarity of outer magnetism matching therewith. A fixed tube (31) cooperates with the conductive post (2) to realize on and off, thus cooperatively changing single magnetic pole adaptation and direction limitations of existing sensors, improving the flexibility of action sensing for a robot, and being able to effectively reduce the number of configured sensors. The inner cavity of the plastic box (1) is divided by lateral and vertical separators and can be filled with insulation paste, thereby improving the overall operation stability.

Description

technical field [0001] The invention relates to the technical field of magnetic switches, in particular to a position detecting magnetic sensor for automatic control. Background technique [0002] The magnetic proximity switch is a kind of proximity switch, which can sense the change of the positional relationship through the magnetic element, and convert the non-electric or electromagnetic quantity into the required electrical signal, so as to achieve the purpose of control or measurement. For robot application technology, automatic navigation and position detection are the core technologies to realize intelligent control, and the position detection and execution control scheme provided by the proximity switch has advantages that other controllers do not have.

AI Technical Summary

Problems solved by technology

The current magnetic proximity switches realize position sensing through magnetic field detection. Most of the types are Hall type, magnetic group type, reed type, etc., and the core magnetic sensitive elements are mostly imported from abroad, with long production cycle and core technology. Controlled by others, leading to high costs

In the fields of robots, automation control equipment, and intelligent equipment manufacturing, the position changes and motion perception between parts are complex, while the existing external magnetic drive induction is linear control, and the external and internal magnets need to distinguish the NS polarity to achieve the same phase. Therefore, the perception and control system needs to set a lot of unique magnetic switches, which leads to the complexity of the overall layout and increases the difficulty of manufacturing
