Magnetic detecting device of intelligent electric permanent magnetic chuck

Abstract

The present invention discloses a magnetic detection device of an intelligent electric permanent magnetic chuck. The magnetic detection device includes a template, a plurality of blind die holes are arranged in the back side of the template, lead gaps are arranged among the blind die holes, a magnetic detection coil is arranged on the bottom of each blind die hole, a magnetic generation device isfixed on the top of the magnetic detection coil, the back face of the template is provided with a cover plate which is fixedly connected with the template via a screw and tightly presses the magneticgeneration device on the opening of the blind die hole. The invention aims to calculate the magnetic force generated by each die hole and gather the magnetic force, the magnetic force is converted into the magnetic attraction force, and the magnitude of the magnetic force can be known in real time on a liquid crystal display of a controller after conversion, and at the same time, whether the template is completely magnetically attracted with an attracted object can be judged via the magnitude of the magnetic force, the operation is simple, and the safety accidents are reduced.

Description

technical field [0001] The invention relates to the field of magnetic suction devices, in particular to a magnetic detection device for an intelligent electric permanent magnetic chuck. Background technique [0002] 1. The old electro-permanent magnetic sucker installs a large mold hole on the front or back of the mold, and several single magnetic groups are arranged in the mold hole, and then filled with resin, and then covered with a cover plate to waterproof , anti-deviation and other functions, the magnetic interference between the magnets of several single magnetic components placed in this large mold pit is too large, the suction force of the suction cup is weakened, and the forward transmission of the magnetic force is affected; 2. The old electropermanent magnetic chuck has no magnetic force detection coil. It is impossible to judge whether there is magnetism, the magnitude of the magnetic force cannot be judged, and it is impossible to know whether there is a proble...

The old electro-permanent magnetic sucker installs a large mold hole on the front or back of the mold, and several single magnetic groups are arranged in the mold hole, and then filled with resin, and then covered with a cover plate to waterproof , anti-deviation and other functions, the magnetic interference between the magnets of several single magnetic components placed in this large mold pit is too large, the suction force of the suction cup is weakened, and the forward transmission of the magnetic force is affected; 2. The old electropermanent magnetic chuck has no magnetic force detection coil. It is impossible to judge whether there is magnetism, the magnitude of the magnetic force cannot be judged, and it is impossible to know whether there is a problem with the die hole. It can only be judged by experience or tested one by one to detect faults; at the same time, it also increases the occurrence of safety accidents
