PLC-based disc-type motor stator coil inserting machine control system

Abstract

The invention discloses a PLC-based disc-type motor stator coil inserting machine control system. The system comprises a sensor detection portion, a PLC programmable controller, a control portion anda man-machine interaction portion. The PLC programmable controller comprises an analog input unit, an analog output unit, a switch quantity input unit, a switch quantity output unit, and a communication interface. The communication interface of the PLC programmable controller is connected to the man-machine interaction portion. The analog input unit and the switch quantity input unit of the PLC programmable controller are connected to the sensor detection portion. The analog output unit and the switch quantity output unit of the PLC programmable controller are connected to the control portion.A winding motor and a bobbin rotation motor control a winding round bar and a bobbin, which can effectively prevent a winding looseness condition caused by different speeds of the winding round bar and the bobbin during winding, and prevent wires from being entwined. A winding tension detection sensor is added so that a tension remains constant and inserted wires are tighter.

Description

technical field [0001] The invention relates to the field of mechanical control systems, in particular to a PLC-based control system for a stator wire inserting machine of a disc motor. Background technique [0002] The wire embedding machine is a mechanical production equipment for embedding the iron core of the motor into the coil. At present, most of the stator processing processes are to roll the copper wire into the wire mold, and then manually embed the copper coil into the motor core. This processing method has low efficiency, high requirements for manual skills, and loose artificial wire embedding. Disadvantages affect the performance of the stator. [0003] The mainstream controllers used in the existing wire embedding machine control system are PLC and single-chip microcomputer. For large-scale supporting projects, the use of single-chip microcomputer systems has the advantages of low cost, easy manufacturing, and high benefits, but at the same time has poor stab...

[0004] The document with the application number 201310625113.6 discloses a semi-automatic wire insertion machine. Although the automatic wire insertion is realized to a certain extent, its shortcoming is that the coil cannot be guaranteed to be in a state of constant tension during the winding process, which will not only cause the motor The increase in the amount of enameled wire will increase the cost of the motor, and it will also lead to loose winding structure and wire embedding of the wire embedding machine, which will eventually affect the performance of the motor

The document with application number 201410393730.2 discloses a semi-automatic horizontal thread inserting machine. This thread inserting machine realizes automatic thread inserting to a certain extent, but its disadvantage is that it is easy to cause problems when pushing the thread. If the thrust is excessive, it may It will cause the enameled wire to be stretched and damaged, which will reduce the performance and quality of the motor

[0005] Furthermore, from the perspective of the PLC-based control system of the thread insertion machine, in the currently published patents, the control system of the thread insertion machine is too simple, the entire system is controlled by the main controller PLC, and there is not much information between the various modules Feedback, can not achieve fine control
