Sucker controller

Abstract

The invention relates to the electrical control industry of mechanical processing, in particular to a sucker controller which consists of an air switch, a transformer, a rectifier, an air switch, a current relay, a magnetic-absorbing relay, a demagnetization resistor and a demagnetization relay; the air switch is connected with the primary side of the transformer in series; the secondary side of the transformer is firstly connected with the rectifier in series, later connected with the air switch and the current relay in series, and then connected with a return circuit which is formed by the parallel connection of the magnetic-absorbing relay and a demagnetization return circuit in series, and finally connected with a sucker. The demagnetization resistor and the demagnetization relay in the demagnetization return circuit are connected in series. The sucker controller has the advantages of simple demagnetization return circuit, fast demagnetization speed, and low failure rate.

Description

Technical field:

[0001] The invention relates to the electrical control industry of mechanical processing, in particular to a sucker controller. Background technique:

[0002] At present, the demagnetization methods of the existing magnetic chuck controllers are all realized by applying gradually decreasing positive and negative polarity voltages to the chuck, the control is complicated, the cost is high, and the demagnetization time is long. Invention content:

[0003] The invention provides a fast demagnetization method, so as to solve the problems of complicated demagnetization circuit and long demagnetization time in the existing sucker controller.

[0004] In order to achieve the above object, the technical solution of the present invention is: sucker controller, which is composed of air switch, transformer, rectifier, air switch, current relay, magnetism relay, demagnetization resistor and demagnetization relay, and the air switch is connected in series with the prim...
