Problems solved by technology

Manual paper insertion has the following disadvantages: First, the insulating paper does not fit tightly with the inner wall of the slot, and there is a gap, which directly affects the next winding process, and the enameled wire slot is full after winding, and the manual slot cover paper is strong. , the process is cumbersome
Second, the labor intensity of the operators is high and they are prone to fatigue, which further affects the quality of paper insertion
Third, low production efficiency
Fourth, increase the labor cost of the employer
[0004] The Chinese patent with the notification number CN104104195B discloses an automatic paper insertion machine for motor rotor insulation paper. This device also needs to use an indentation device. Automated assembly line work

Abstract

The invention relates to the assembling field of the motor stator or rotor insulation paper, and discloses a paper inserting machine for assembling the motor stator insulation paper or rotor insulation paper. The paper inserting machine comprises a rack, a mounting rack is arranged on the rack, a feeding mechanism, a cutting mechanism, and a ramming mechanism are arranged on the mounting rack; thefeeding mechanism comprises a conveying track arranged on the mounting rack and a conveying power part for conveying the material to the cutting and ramming mechanisms; the cutting mechanism comprises a cutting power part and a cutting mode fixing block for cutting; the ramming mechanism comprises a ramming power part and a ramming module for driving the material assembling; a placing slot for placing the material is arranged in a material blocking seat, the placing slot is communicated with the conveying rack, the cutting power part drives the cutting mode fixing block to push the material into the placing slot; the ramming mechanism is located at an upper part of the placing slot, the ramming power part drives the ramming module to perform ramming assembling on the material. The paper inserting machine has the advantages of being high in working efficiency, low in fault rate, and compact in structure.

Description

technical field [0001] The invention relates to the field of motor rotor or stator assembly, in particular to a paper insertion machine for assembling motor stator insulation paper or rotor insulation paper. Background technique [0002] Insulating paper is widely used in motor stators because of its excellent insulating ability and strong mechanical properties. The number of wire slots of brushless motors is small and the slot type is wide, so the assembly of its insulating paper is particularly difficult. At present, the insertion of insulating paper in domestic brushless motor slots basically relies on manual work. Manual paper insertion has the following disadvantages: First, the insulating paper does not fit tightly with the inner wall of the slot, and there is a gap, which directly affects the next winding process, and the enameled wire slot is full after winding, and the manual slot cover paper is strong. , The process is cumbersome. Second, the operating personnel...
