Technical Field

[0001] This invention relates to the field of stator assembly technology, and in particular to a paper insertion machine. Background Technology

[0002] The stator is the stationary part of a motor or generator, mainly composed of a stator core and coils wound around it. To prevent interference between the coils on the stator, insulating paper sheets are inserted into the winding slots of the stator core as a separator. In existing technology, a paper inserter inserts the insulating paper into the winding slots of the stator. For stator cores with high insulation requirements, such as flat wire motor stators and long core high-slot stators, to ensure insertion accuracy, the formed insulating paper is mostly inserted into the winding slots of the stator core from top to bottom. For example, utility model patent CN223414757U discloses a paper insertion device, including: a frame, including a mounting platform and a mounting plate disposed on the upper surface of the mounting platform, and a stator fixed below the mounting platform; an indentation structure for indenting two side indentations on both sides of the insulating paper and two center indentations on the insulating paper, the two center indentations being spaced apart and located between the two side indentations; a bending structure including a first bending mechanism and a second bending mechanism, the first bending mechanism being used to bend the insulating paper along the side indentations, the second bending mechanism being used to bend the insulating paper along the two center indentations and overlap the two sides of the insulating paper; and a paper pushing structure for pressing the insulating paper from top to bottom into the stator slot of the stator through the second bending mechanism.

[0034] A protective cover 6 is installed on the frame 1 to cover the paper mold mounting frame 101, the pre-feeding paper module 2, the paper forming module 3, and the feeding module 5.

[0036] When the feeding rack 51 corresponds to the paper forming module 3, the feeding rotation mechanism 54 drives the feeding platform 52 to rotate, so that the winding slots of the stator core 9 loaded on the feeding platform 52 pass through the paper forming module 3 in sequence. The paper forming mold can press, feed, form, cut and push the insulating paper 8 conveyed by the pre-feeding paper module 2 in sequence, thereby realizing the automatic paper insertion processing of each winding slot on the stator core 9.

[0037] When the feeding rack 51 is offset from the paper forming module 3, the travel space 103 below the paper forming module 3 is freed up, allowing the operator to stand without having to bend over. This improves the operator's disassembly and operation space, reduces interference between confined spaces and mechanisms, and allows the operator to quickly disassemble and replace the paper forming module 3 according to the winding slot requirements of different stator cores 9.

[0038] A material handling housing 602 is provided on the side of the protective cover 6 away from the paper mold mounting frame 101. Material handling ports 603 are provided on the top surface and side wall of the material handling housing 602, and are connected to the travel space 103.

A positioning frame 10 is provided on the frame 1 near the loading port 603. 5. A positioning block 106 is provided on the positioning frame 105. When the feeding sensor 104 senses the feeding frame 51, the controller 7 stops the feeding translation mechanism 53. The positioning block 106 abuts against the stator core 9 placed on the feeding platform 52. The operator can control the feeding lifting mechanism 55 through the controller 7 to adjust the height of the feeding platform 52 so that the stator core 9 after paper insertion extends to the outside of the pick-up and drop-off port 603 for the pick-up and drop-off operation of the stator core 9.
