The positioning block 8 matches the mark groove on the injection molded stator core 11, and the tool frame 1 is provided with iron blocks 9 that guide the injection molded stator core 11 when it is placed from top to bottom. The iron blocks 2 are provided with foolproof blocks 15 that can effectively prevent the injection molded stator core 11 from being placed upside down, improving the safety and stability during production.

[0032] The iron block 9 is provided with fool-proof block 15 on the upper side close to the injection molded stator core 11, the injection molded stator core 11 has the distinction of right and left due to the smooth surface and rough surface of the outer circle of the end, so the right and left also have requirements when being put in, if the rough surface is installed downward, the problem of skewing and distortion will be caused, when the smooth surface of the injection molded stator core 11 can be easily put into the jig 1, it indicates that the injection molded stator core 11 is placed correctly, and the fool-proof block can help the staff to quickly distinguish the right and left of the injection molded stator core 11.

[0033] The injection molded stator core 11 is externally provided with a detachable inner sleeve 5, and the outer circle of the inner sleeve 5 is matched with the inner circle of the jig 1, when the size of the injection molded stator core 11 needing to be wound is smaller than that of the jig 1, the inner sleeve 5 matched with the jig 1 is sleeved on the injection molded stator core 11 to realize subsequent winding, without increasing additional winding jig, and the universality of the jig is improved.

[0034] When the size of the injection molded stator core 11 needing to be wound is smaller than that of the jig 1, first, the matched size of the inner sleeve 5 is selected, and the injection molded stator core 11 is placed into the inner sleeve 5 from bottom to top, the injection molded stator core 11 is positioned by the inner circle rib 52 on the inner sleeve 5, at this time, the mark groove on the injection molded stator core 11 is matched with the inner circle rib 52, to ensure that the injection molded stator core 11 will not rotate in the inner sleeve 5, to ensure the accuracy and consistency of the winding of the injection molded stator core, the blocking opening on the inner sleeve can avoid the injection molded stator core from jumping out of the jig during winding, and according to the height of the injection molded stator core 11 needing to be wound, the aluminum ring pad 6 of the matched height is placed on the boss 10 in the jig 1; then, the inner sleeve 5 with the injection molded stator core 11 is placed on the jig 1, the jig 1 is provided with positioning block 8 matched with the outer circle groove 51 on the inner sleeve 5, to position the inner sleeve 5 placed in the jig 1, to avoid the rotation of the inner sleeve 5 in the jig 1, and the spring clamp block 21 presses the circumferential outer part of the inner sleeve 5, to avoid the phenomenon that the inner sleeve 5 drives the injection molded stator core 11 to jump up and down during winding; finally, the jig is fixed on the automatic winding machine through the bottom fixing block 4 for subsequent winding.

[0035] The outer circle of the inner sleeve frame 5 is provided with an outer circle groove 51 along the height direction, and the inner circle of the inner sleeve frame 5 is provided with an inner circle rib 52 along the height direction. The positioning block 8 cooperates with the outer circle groove 51, and the inner sleeve frame 5 is prevented from rotating in the tool frame 1 during automatic winding through the positioning block 8, thereby affecting the efficiency of automatic winding.

[0038] The tool frame 1 is provided with a detachable and replaceable aluminum ring pad 6 and a boss 10 supporting the aluminum ring pad 6. The outer wall of the aluminum ring pad 6 is in close contact with the inner wall of the tool frame 1. When the height of the injection molded electronic core 11 to be wound is different, the tool does not need to be disassembled and replaced, and only the aluminum ring pad 6 of different height needs to be replaced, which is convenient, simple and fast, increases the universality of the winding tool, saves a lot of manpower and material resources during tool replacement, and prolongs the service life of the machine and the tool. The aluminum ring pad 6 and the inner circle of the tool frame 1 form a containing cavity for placing the injection molded stator core 11. By replacing the aluminum ring pad 6 of different heights, the containing cavity for placing the injection molded stator core 11 has different heights.

[0039] The number of winding columns 7 on the existing tool is very small, which leads to great limitations during winding. If the corresponding winding nozzle position of some products does not correspond to the winding column 7, winding is not possible, and winding can only be performed from another column, which is very troublesome. In the present tool, the number of winding columns 7 is increased to 12, making the bridge line clear and obvious during wire routing.

[0040] The winding column 7 is specifically provided with 12 winding columns 7. The winding column 7 is movably inserted into the upper surface of the tool frame 1, and the winding column 7 corresponds in position to the iron block 9, increasing the wire routing options during winding of the injection molded stator core 11, making the bridge line clear and obvious during wire routing, and the winding column 7 is movably arranged, facilitating replacement after wear.

[0041] The above embodiments are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application, and any equivalent changes or modifications made according to the spirit and essence of the present application shall be covered within the protection scope of the present application.
