Insertion device for motor stator slot insulation paper

Abstract

The invention provides an insertion device for motor stator slot insulation paper. The device comprises a rack, an unreeling device, a heating device, an indentation device, a preforming device, a first forming device, a paper feeding device, a corner cutting device, a paper inserting device, a cutting-off device, a second forming device, a dividing device, a stator positioning device, and an electric appliance cabinet assembly. Through dividing a one-step forming process of insulation paper into multistage forming, forming internal stress of the insulation paper is released in each forming process, and in repeated heating and forming processes, stability of the formed insulation paper is ensured. The insertion device is driven by a servo motor, length of paper feeding of the insulation paper can be accurately controlled, and when motor stack thickness changes, just a setting value of paper feeding length needs regulating. The device is simple and convenient in operation, reduces length error of insulation paper feeding, and reduces errors of insulation paper length and motor stack thickness and height after the insulation paper is inserted, so as to improve integrated performance of a motor.

Description

technical field [0001] The invention relates to a paper inserting device, in particular to a device for inserting insulating paper in a motor stator slot. Background technique [0002] The motor refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. The motor consists of a rotor and a stator. On the stator core of the motor, there are often multiple wire slots and embedded excitation windings to ensure that the motor can Work normally; since the excitation winding is composed of wires, in order to avoid conduction between the excitation winding and the stator core, even if the stator core and the excitation winding are insulated, there are currently two ways: the first way, Using injection molding to form an insulating layer with a thickness of 0.5 to 1 mm on the wire slot of the iron core and the surface of the iron core. Using this method to form an insulating layer in the wire ...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the following problems in the prior art: In the thermoforming technology of the insulation paper insertion equipment for the stator slot of the motor, after the insulation paper is inserted into the wire groove, the wire groove must be immediately wound with coils, otherwise the insulation paper is easily deformed during the cooling process. Affect the fitting accuracy with the stator slot, affect the arrangement of the coil winding, and it is easy to rework and redo, which affects the work efficiency; the invention provides a device for inserting insulating paper into the stator slot of a motor, including a frame, an unwinding device, The heating device, the creasing device, the paper feeding device, the corner cutting device, the paper inserting device, the cutting device, the second forming device and the electrical cabinet assembly are characterized in that: it also includes a preforming device and a first forming device; the preforming The device and the first forming device are located between the creasing device and the paper feeding device, and the insulating paper is pre-shaped and processed for the first time
