Description

Technical Field

[0001] This utility model belongs to the field of wire storage, and specifically relates to a multi-strand wire storage structure and a wire dispensing device containing the structure. Background Technology

[0002] In the motor industry, multi-wire parallel winding is a widely used process. This process increases the number of turns and conductor cross-sectional area of ​​the motor winding, thereby improving the power density and efficiency of the motor and reducing copper losses. For the same cross-section, multi-wire parallel winding makes coil winding easier, and the motor slot can be designed to be narrower, which is more conducive to improving motor performance. Typically, two or four enameled wires are used for parallel winding. For mass production, several spools of enameled wire can be laid side-by-side, with one wire on each spool, and the coils wound together. However, when multiple strands of enameled wire are wound together simultaneously, such as 10 strands or 20 strands, a large number of spools of enameled wire are required, occupying a large amount of space. The actual amount of enameled wire prepared is also large, resulting in low factory utilization and high capital occupation. Alternatively, single-spool enameled wire can be cut according to the number of strands to be wound and the required winding length, laid flat, and then wound together to form a coil for the motor. This operation requires multiple people to complete, wasting labor, being inefficient, not suitable for on-demand use, and not suitable for mass production. In addition, multiple strands of enameled wire occupy a large amount of space, and the enameled wires are prone to knotting. This method of laying wire is also limited by the cutting length and placement position of the enameled wire. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Example 1 like Figure 1-3As shown, a multi-strand wire storage structure includes several wire storage wheels 1 and a rotating shaft 2. The several wire storage wheels 1 are arranged side by side and located outside the rotating shaft 2. The rotating shaft 2 is connected to a first fixed support frame 3 and a movable support frame 4. The first fixed support frame 3 is connected to at least two first connecting rods 301. One end of the first connecting rod 301 is rotatably connected to the first fixed support frame 3, and the other end of the first connecting rod 301 is rotatably connected to a support rod 5 for abutting against the inner wall of the wire storage wheel 1. The support rod 5 is arranged parallel to the rotating shaft 2. The movable support frame 4 is slidably connected to the rotating shaft 2. The movable support frame 4 is connected to a second connecting rod 401 with a number matching the number of first connecting rods 301. One end of the second connecting rod 401 is rotatably connected to the movable support frame 4, and the other end of the second connecting rod 401 is rotatably connected to the middle of the first connecting rod 301. A clamping nut 402 is provided on the side of the movable support frame 4 away from the first fixed support frame 3. The clamping nut 402 is threadedly connected to the rotating shaft 2. This multi-strand wire storage structure has multiple wire storage wheels 1 arranged side by side on the outside of the support rod 5. The movable support frame 4 can move laterally along the rotating shaft 2. By tightening the clamping nut 402 and pushing the movable support frame 4 inward, the second connecting rod 401 supports the first connecting rod 301, causing the support rod 5 to expand outward, thereby resisting and fixing the wire storage wheel 1.

[0022] To ensure the outward support effect of the support rod 5, the rotating shaft 2 is connected to a second fixed support frame 7, and the second fixed support frame is located on the side of the first fixed support frame 3 away from the movable support frame 4; the second fixed support frame 7 is connected to at least two third links 701, one end of the third link 701 is rotatably connected to the second fixed support frame 7, and the other end of the third link 701 is rotatably connected to the support rod 5.

[0023] Specifically, both the first fixed support frame 3 and the second fixed support frame 7 are fixed to the rotating shaft 2 by slotted conical set screws, so that the first fixed support frame 3 and the second fixed support frame 7 can be stably installed on the rotating shaft 2. The movable support frame 4 has a through hole in the middle for the rotating shaft 2 to pass through, so as to facilitate the movement of the movable support frame 4 along the rotating shaft 2. The two ends of the first connecting rod 301 are connected to the first fixed support frame 3 and the support rod 5 by cylindrical pins, respectively. The two ends of the second connecting rod 401 are connected to the movable support frame 4 and the support rod 5 by cylindrical pins, respectively. The two ends of the third connecting rod 701 are connected to the second fixed support frame 7 and the support rod 5 by cylindrical pins, respectively. The support rod 5 has a long strip-shaped first slot and a second slot. The cylindrical pin for connecting the first connecting rod 301 is located in the middle of the inner side of the first slot, and the cylindrical pin for connecting the third connecting rod 701 is located in the middle of the inner side of the second slot, so as to facilitate the rotational connection effect of the first connecting rod 301, the second connecting rod 401 and the third connecting rod 701.

[0024] A return spring 6 is provided between the first fixed support frame 3 and the movable support frame 4. The return spring 6 is sleeved on the outside of the rotating shaft 2. With the help of the return spring 6, the movable support frame 4 is pushed outward, which causes the support rod 5 to retract inward, which facilitates the installation and use of the wire storage wheel 1.

[0025] The side of the support rod 5 near the wire storage wheel 1 is arc-shaped. When the support rod 5 retracts inward, the wire storage wheel 1 can easily rotate around the rotating shaft 2, which is beneficial for wire feeding and coil winding.

[0026] There are three first connecting rods 301, which are arranged at equal angles along the circumference on the first fixed support frame 3, i.e., three support rods 5 are used. When the support rods 5 expand outward, they can provide better fixed support for the wire storage wheel 1. Specifically, there are three second connecting rods 401, which are arranged at equal angles along the circumference on the movable support frame 4; and there are three third connecting rods 701, which are arranged at equal angles along the circumference on the second fixed support frame 7.

[0027] Both ends of the support rod 5 are provided with limiting protrusions 501. The limiting protrusions 501 restrict the lateral movement of the wire storage wheel 1, which can prevent the wire storage wheel 1 from slipping off the support rod 5.

[0028] When storing wire on the winding machine, the clamping nut 402 needs to be tightened and the wire storage wheel 1 fixed. Furthermore, to facilitate fixing the multi-strand wire storage structure to the winding station of the winding machine, one end of the rotating shaft 2 is provided with a connecting slot 201 for connecting the winding machine connector 8, and the other end of the rotating shaft 2 is provided with a positioning hole 202 for inserting the winding machine top rod 9. This allows the winding parameters of the winding machine to be set according to the length of a single wire of the motor, including length, number of groups, and spacing. The winding machine divides the single-axis enameled wire into several equal-length segments and stores them separately on multiple wire storage wheels 1 of the wire storage structure. Specifically, the wire storage wheel 1 is annular, and its outer wall is provided with annularly arranged wire storage grooves 101. The width of the wire storage grooves 101 gradually decreases from the opening inwards to facilitate stable winding of the enameled wire within the wire storage grooves 101.

[0029] Example 2 like Figure 4-5 As shown, a wire feeding device includes a support base 10, on which a multi-strand wire storage structure is provided. The support base 10 includes a base plate 1001 and two support plates 1002, which are respectively disposed on both sides of the base plate 1001. The upper part of the support plate 1002 is provided with a shaft 2 groove for supporting a rotating shaft 2. Specifically, the support plate 1002 is connected to the base plate 1001 by hexagonal socket screws; and the shaft 2 groove on the upper part of the support plate 1002 can be a V-shaped groove to facilitate the mounting of the rotating shaft 2.

[0030] When the wire is released to wind the coil, the clamping nut 402 needs to be loosened so that the support rod 5 retracts inward and the wire storage wheel 1 is released. Then each wire storage wheel 1 can rotate freely around the rotating shaft 2. When the multi-strand wire storage structure is set on the support base 10, the enameled wire end can be pulled out from each wire storage wheel 1, and after being wired together, they are wound together to form a coil for motors.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
