Description

Technical Field

[0001] This utility model relates to the field of insertion mechanisms, and in particular to an insertion mechanism for H-shaped paper in a wire embedding machine. Background Technology

[0002] In the manufacturing process of electric motor and generator stators, the winding machine is one of the core pieces of equipment, used to precisely embed the coils into the stator core slots. To ensure the insulation performance between coils, spacer paper needs to be inserted between adjacent coils. H-type spacer paper is widely used due to its unique geometric structure (symmetrical support on both sides and concave in the middle), which can effectively prevent coil displacement and insulation breakdown.

[0003] Currently, most small and medium-sized factories still rely on manual insertion of H-type photographic paper. Operators must manually align the photographic paper with the coil gap and insert it using simple tools. This manual insertion method is prone to causing the photographic paper to tilt or misalign due to fatigue or visual deviation. Some companies use semi-automatic insertion devices that use robotic arms to hold and push the photographic paper. However, this rigid insertion method is prone to damaging the photographic paper. Because the robotic arm lacks a cushioning design, the edges of the photographic paper are easily subjected to concentrated mechanical stress during the pushing process, which can easily lead to tearing or deformation, thereby reducing the yield. Utility Model Content

[0004] The purpose of this invention is to provide an insertion mechanism for H-type paper in a wire embedding machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an insertion mechanism for H-type paper in a wire-inserting machine, comprising:

[0006] Guide;

[0007] A positioning mechanism, which is connected to the other end of the guide;

[0008] A support mechanism, connected to a positioning mechanism, is used to support and advance the H-shaped paper.

[0009] Preferably, one end of the guide is truncated cone-shaped, and the outer diameter of the guide gradually increases towards the positioning mechanism.

[0010] Preferably, one end of the guide has a first groove, and the other end of the guide has a second groove.

[0011] Preferably, the positioning mechanism includes:

[0012] A pad, the pad being installed inside the second groove on the guide;

[0013] A locator is mounted on the other end of the guide, and the pad is connected to the locator.

[0014] Preferably, the positioning mechanism further includes:

[0015] A plurality of spring pins are inserted and installed inside the positioner, and the plurality of spring pins are arranged in a ring array.

[0016] Preferably, the positioner has multiple slots arranged in a circular array, and the position of the positioner corresponds to that of the spring pin.

[0017] Preferably, the support mechanism includes:

[0019] H-type photo paper support blades are arranged in a circular array outside the H-type photo paper support blade holder, and the positions of the H-type photo paper support blades correspond to the spring pins. A pin is rotatably inserted and installed on the top of each H-type photo paper support blade, and brackets are fixedly connected to both ends of the pin. The brackets are fixedly installed inside the slot.

[0020] The technical effects and advantages of this utility model are as follows:

[0021] This utility model utilizes a combination of positioning and support mechanisms. By linking the insertion mechanism with the main control system of the winding machine, it reduces the time required compared to manual insertion. At the same time, its insertion rhythm is perfectly matched with the high-speed winding machine's beat, eliminating production line stagnation caused by manual intervention, saving time, increasing material yield, and reducing worker workload.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides, for example Figure 1-3 The inserted mechanism for an H-shaped paper in a wire embedding machine, as shown, includes: a guide 4; a positioning mechanism connected to the other end of the guide 4; and a support mechanism connected to the positioning mechanism. The support mechanism is used to support and advance the H-shaped paper. When the positioning mechanism moves upward, as... Figure 1 The H-shaped photo paper support knife 10 will contact the H-shaped photo paper 3. As the positioner 6 continues to move upward, the H-shaped photo paper support knife 10 will support the H-shaped photo paper 3. When the H-shaped photo paper 3 is restrained by the coil wrap 2 and cannot continue to move outward, the positioner 6 continues to move upward, and the H-shaped photo paper support knife 10 rotates inward around the pin 8 until it reaches the desired position. Figure 2 The red line indicates the position of the H-shaped photo paper support knife 10, which protects the H-shaped photo paper 3 from damage by strong force. By linking this insertion mechanism with the main control system of the winding machine, it is faster than manual insertion, and its insertion rhythm is perfectly matched with the high-speed winding machine's beat, eliminating production line stagnation caused by manual intervention. Through the linkage design of the pin shaft 8 and the spring pin 7, the angle of the H-shaped photo paper support knife 10 can be dynamically adjusted according to the insertion resistance of the H-shaped photo paper 3. Figure 2 As shown, this avoids shear force concentration, thus facilitating a higher yield.

[0028] The motor stator 1, as the core component of the winding machine, consists of an iron core and slots used to fix the coil coils 2. Its slot structure provides space for the insertion of the H-shaped photographic paper 3, ensuring precise fit between the coil and the photographic paper to achieve electromagnetic performance and insulation requirements. The pre-wound coil coils 2, after being embedded in the stator slots, form the motor windings. They must be used in conjunction with the H-shaped photographic paper 3 to prevent short circuits between adjacent coils due to contact. The H-shaped photographic paper 3 is an insulating phase-isolating material; its symmetrically supported sides and concave middle H-shaped structure can be embedded in the stator slots to isolate adjacent coil coils 2, preventing displacement and insulation breakdown.

[0029] The guide 4 has a frustum-shaped end and guides the H-shaped photographic paper 3 along a preset path into the stator slot. The guide 4 is linked to the spring pin 7 to achieve buffering and adaptive guidance. The outer diameter of the guide 4 gradually increases towards the positioning mechanism, thus gradually increasing as the guide 4 intersects with the motor stator 1. The frustum-shaped tip design prevents lateral displacement of the H-shaped photographic paper 3 due to rigid right-angled edges. Furthermore, the adaptive path adjustment at the tip of the guide 4 causes slight sliding friction when it contacts the motor stator 1, dynamically correcting the insertion angle deviation and ensuring that the H-shaped photographic paper 3 enters the gap of the coil 2 along the preset path, making the insertion of the guide 4 smoother. One end of the guide 4 has a first groove, and the other end has a second groove, which facilitates the installation of the pad 5.

[0030] The positioning mechanism includes: a pad 5, which is installed inside the second groove on the guide 4; a positioner 6, which is installed at the other end of the guide 4, and the pad 5 is connected to the positioner 6; the positioning mechanism also includes: spring pins 7, multiple spring pins 7 are inserted and installed inside the positioner 6, and the multiple spring pins 7 are arranged in a ring array. The positioner 6 has multiple slots arranged in a ring array, which facilitates the rotation of the H-type photo paper support knife 10 relative to the positioner 6. The positions of the positioner 6 and the spring pins 7 correspond to each other. The pad 5 is used to fix the base of the guide 4 and the positioner 6, providing structural stability. The positioner 6 is the core actuator for driving the H-type photo paper 3 to complete the insertion action. The stroke of the H-type photo paper support knife 10 is controlled by its up-and-down movement, synchronized with the main control system of the winding machine. The spring pins 7 provide elastic buffering; when the insertion resistance of the H-type photo paper 3 is too high, they absorb mechanical stress through compression to prevent the photo paper from breaking.

[0031] The support mechanism includes: an H-type photo paper support blade holder 9, one end of which is connected to a positioner 6; and H-type photo paper support blades 10, multiple H-type photo paper support blades 10 arranged in a circular array outside the H-type photo paper support blade holder 9, with the positions of the H-type photo paper support blades 10 corresponding to the spring pins 7. A pin shaft 8 is rotatably inserted into the top of each H-type photo paper support blade 10, with brackets fixedly connected to both ends of the pin shaft 8. The brackets are fixedly installed inside the slot. The pin shaft 8 serves as a rotation fulcrum for the H-type photo paper support blade 10, allowing the support blade to dynamically adjust its angle according to the insertion resistance. Figure 2 As shown, to avoid concentrated shearing force, the H-shaped photo paper support knife holder 9 is used to fix the base of the support knife 10, and cooperates with the pin 8 to form a rotating mechanism. The H-shaped photo paper support knife 10 is used to directly contact and support the end of the H-shaped photo paper 3, and completes the insertion action under the drive of the positioner 6. The knife head is designed with an arc-shaped cutting edge to reduce contact pressure and prevent the H-shaped photo paper 3 from tearing.
