Demagnetizing module for mechanical arm

Abstract

The invention discloses a demagnetizing module for a mechanical arm. The demagnetizing module comprises a first resistor, an electromagnet, a first switch and a controllable power supply; wherein one end of the controllable power supply is electrically connected with one end of the first switch, while the other end of the controllable power supply is electrically connected with one end of the electromagnet, and two ends of the first resistor are respectively connected with the other end of the first switch and the other end of the electromagnet electrically; wherein the demagnetizing module for the mechanical arm further comprises a second resistor, a second switch, a diode and a capacitor; one end of the second resistor and one end of the capacitor are electrically connected with one end of the controllable power supply, and two ends of the second switch are respectively and electrically connected with the other end of the second resistor, the other end of the capacitor and the cathode of the diode, and the anode of the diode is electrically connected with the other end of the first switch. According to the demagnetizing module provided by the invention, a reversed attenuation current flows through a material piece when the electromagnet is powered off, and the material piece is demagnetized instantly and falls to a work position, thereby solving the technical problem that the production rate is reduced because material pieces are magnetized by the conventional mechanical arm and cannot be released timely.

Description

technical field [0001] The invention relates to the field of automatic production and manufacturing, in particular to a degaussing module for instantaneously eliminating residual magnetism and a magnetic force adsorption manipulator. Background technique [0002] With the development of science and technology, more and more manipulators are used in the manufacturing industry. From simple feeding mechanisms to complex micro-electronic component placement processes, a variety of manipulators are widely used. Although the emergence of manipulators provides great convenience for production, there are also certain problems. [0003] For example, in the feeding link, the magnetic adsorption manipulator with electromagnet will be magnetized during the process of picking up the material, so that it has a certain residual magnetism. As a result, when unloading, there will be problems such as the materials cannot be put down in time, or cannot fall vertically to the designated positi...
