[0017] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0018] Example:

[0019] like Figures 1 to 3 As shown, a coil winding mold comprises: a mold base 1, the mold base 1 is fixedly installed on the winding equipment, a module 2 is fixedly connected to the top center of the mold base 1, a mold guide groove 201 is provided on the top surface of the module 2, and the mold guide groove 201 is a spiral structure. A mold sleeve 9 is provided above the module 2, and a center column 10 is fixedly connected to the top of the mold sleeve 9. The center column 10 is fixedly connected to the winding motor drive end of the winding equipment, a wire reel positioning hole is provided at the center of the top surface of the module 2, a wire reel inserted into the wire reel positioning hole is fixedly connected to the bottom of the mold sleeve 9, a coil body 11 is provided on the outside of the wire reel and between the mold sleeve 9 and the module 2, and a mold base 1 is provided. There is a wire clamping mechanism for clamping and fixing the pin at one end of the coil body 11. During the coil winding process, the flat wire is placed in the mold guide groove 201 on the top surface of the module 2. The winding motor of the winding equipment drives the middle column 10 and the mold sleeve 9 to rotate, and the flat wire is wound into the coil body 11 on the outside of the wire reel. During the flat wire winding process, the spiral structure of the mold guide groove 201 is set to assist the coil in winding along the spiral direction of the mold guide groove 201, providing a guiding path for the flat wire winding, avoiding the problem of the flat wire tilting or standing up during the winding process, resulting in unsuccessful coil winding or poor appearance, and improving the yield rate of the coil winding.

[0020] In this embodiment, if Figure 2 and Figure 3 As shown, the edges of the mold guide groove 201 are designed with rounded corners. The rounded corners of the edges of the mold guide groove 201 can prevent the flat wire from being blocked at the edges of the mold guide groove 201. The maximum depth of the mold guide groove 201 is less than the thickness of the flat wire in the coil body 11. The depth design of the mold guide groove 201 ensures that during the coil winding process, the mold guide groove 201 will not protrude beyond the thickness of one circle of the coil, thereby preventing the flat wire of the adjacent layer from being blocked during the coil winding process.

[0021] In this embodiment, if Figure 1 and Figure 2As shown, the wire clamping mechanism includes a first wire clamping claw 4 and a second wire clamping claw 5. The first wire clamping claw 4 and the second wire clamping claw 5 are used together to clamp and fix the pin at one end of the coil body 11. A first wire clamping claw mounting groove is provided at the top of the mold base 1. The first wire clamping claw 4 is partially fixedly connected to the first wire clamping claw mounting groove. A second wire clamping claw mounting groove 101 is provided inside the mold base 1. The second wire clamping claw 5 is installed in the second wire clamping claw mounting groove 101. A driving part is also installed in the second wire clamping claw mounting groove 101. The driving part can be a telescopic cylinder, a hydraulic cylinder, etc. The driving end of the driving part is connected to the second wire clamping claw mounting groove The second wire clamping claw 5 in 101 is fixedly connected, and the driving member drives the second wire clamping claw 5 to move closer to or away from the first wire clamping claw 4. The driving member drives the second wire clamping claw 5 to move away from the first wire clamping claw 4, and opens the clamping area between the second wire clamping claw 5 and the first wire clamping claw 4. Then, one end of the flat wire is placed in the clamping area between the second wire clamping claw 5 and the first wire clamping claw 4. Then, the driving member drives the second wire clamping claw 5 to move closer to the first wire clamping claw 4, and closes the clamping area between the second wire clamping claw 5 and the first wire clamping claw 4, which is used to clamp and fix the flat wire, which helps the coil winding work.

[0022] In this embodiment, if Figure 1 and Figure 2 As shown, the mold base 1 is also provided with a waist-shaped through groove 102 which is connected to the second wire clamping claw installation groove 101. The waist-shaped through groove 102 passes through the mold base 1, and a driving rod 6 is slidably connected in the waist-shaped through groove 102. The second wire clamping claw 5 is fixedly connected to the driving rod 6, and both ends of the driving rod 6 extend to the outside of the waist-shaped through groove 102. A pair of fixing rods 7 are fixedly connected below the driving rod 6 on the outer wall of the mold base 1, and a tension spring 8 is fixedly connected between the fixing rod 7 and the driving rod 6. When the second wire clamping claw 5 and the first wire clamping claw 4 are away from each other, the driving rod 6 moves synchronously with the second wire clamping claw 5. The driving rod 6 moves in the waist-shaped through groove 102 to stretch the tension spring 8. When the second wire clamping claw 5 and the first wire clamping claw 4 are close to each other and closed, the tension spring 8 can reset the driving rod 6 according to its own elastic properties, thereby helping to clamp the second wire clamping claw 5 and the first wire clamping claw 4 closed, thereby improving the clamping and fixing of the flat wire.

[0023] In this embodiment, if Figure 1 As shown, the bottom of the mold base 1 is fixedly connected to a mounting base 3, and mounting holes 301 are provided at the four corners of the mounting base 3. Bolts pass through the mounting holes 301 to fix the mounting base 3 on the winding equipment to provide firm support for the mold base 1.

[0024] Implementation scheme: When in use, the driving member works to drive the second wire clamping claw 5 to move away from the first wire clamping claw 4, and the clamping area between the second wire clamping claw 5 and the first wire clamping claw 4 is opened. By placing the flat wire in the mold guide groove 201 on the top surface of the module 2 and in the clamping area between the second wire clamping claw 5 and the first wire clamping claw 4, the driving member works again to drive the second wire clamping claw 5 to move closer to the first wire clamping claw 4, and the clamping area between the second wire clamping claw 5 and the first wire clamping claw 4 is closed. The tension spring 8 is used to reset the driving rod 6, thereby helping to clamp the second wire clamping claw 5 and the first wire clamping claw 4 together for clamping. The flat wire is fixed, and then the middle column 10 is moved close to the mold base 1, so that the wire reel at the bottom end of the mold sleeve 9 is inserted into the wire reel positioning hole on the module 2, and the winding motor of the winding equipment drives the middle column 10 and the mold sleeve 9 to rotate, and the flat wire is wound into the coil body 11 on the outside of the wire reel. In the process of winding the flat wire, the spiral structure of the mold guide groove 201 is provided to assist the coil in winding along the spiral direction of the mold guide groove 201, providing a guiding path for the flat wire winding, avoiding the problem of the flat wire tilting or standing up during the winding process, resulting in unsuccessful coil winding or poor appearance, and improving the yield rate of the coil winding.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0026] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
