Electromagnet magnetizing and demagnetizing control device and method

Abstract

The invention discloses an electromagnet magnetizing and demagnetizing control device and method. The device comprises a single-chip microcomputer, a power supply circuit, a controller, n electromagnets, n H-bridge integrated chips, n starting channels and n demagnetizing channels, and the power supply circuit is electrically connected with the single-chip microcomputer; the controller is electrically connected with the single chip microcomputer through the ith starting channel so as to send a magnetizing signal used for indicating to magnetize the ith electromagnet to the single chip microcomputer; and the single-chip microcomputer is connected with the ith H-bridge integrated chip through the ith demagnetization channel, the ith H-bridge integrated chip is electrically connected with the ith electromagnet, and the single-chip microcomputer demagnetizes the ith electromagnet connected with the ith H-bridge integrated chip through the ith H-bridge integrated chip when determining that a magnetizing signal used for indicating magnetizing of the ith electromagnet is stopped. The electromagnet is demagnetized through the demagnetization program, the problem that the electromagnet and the workpiece cannot be timely separated at the power-off moment due to magnetic force residues is solved, and stable and accurate placement of the workpiece is improved.

Description

technical field [0001] The application belongs to the technical field of battery component production, and relates to an electromagnet charge and demagnetization control device and method. Background technique [0002] In the production of battery components, it is usually necessary to use workpieces to fix the welding strips. Based on this, a conveying device for conveying workpieces is provided in the battery assembly production equipment, and the conveying device is provided with an electromagnet that attracts the workpieces. When the workpiece needs to be absorbed, the electromagnet is powered on to absorb the workpiece, and when the workpiece needs to be released, the electromagnet is powered off to release the workpiece. [0003] In practical applications, when the handling device releases the workpiece, the electromagnet and the workpiece cannot be disengaged in time due to the residual magnetic force, which will cause the workpiece to be biased and the workpiece can...
