[0017] The technical solution of the present invention is further described below through the accompanying drawings and embodiments.

[0019] Example like Figure 1-6 As shown, the present invention provides a copper coil special-shaped arrangement winding device, including an upper spindle mechanism. The upper spindle mechanism is mainly composed of an upper spindle seat 1, an upper spindle moving mechanism 2, a double upper mold winding mechanism 3, a hot air gun mechanism 4 and a hot air shielding mechanism 5.

[0020] The upper spindle seat 1 is placed on the base plate, and an upper spindle moving mechanism 2 is provided above it. The upper spindle moving mechanism 2 comprises an upper spindle moving motor 6, an upper spindle moving screw 7, an upper spindle moving guide rail 8 and an upper spindle moving plate 9. The upper spindle moving motor 6 is installed on the upper spindle seat 1 and is connected to the upper spindle moving screw 7 through a coupling. Upper spindle moving guide rails 8 are arranged on both sides above the upper spindle seat 1, and the upper spindle moving plate 9 is installed on the guide rails, and the upper spindle moving plate 9 is provided with mounting holes, and the upper spindle moving screw 7 passes through the mounting holes, together forming the upper spindle moving mechanism 2. The mounting hole at the front end of the upper spindle moving plate 9 is used to install the double upper mold winding mechanism 3.

[0021] The upper spindle seat 1 is also provided with a hot air shielding mechanism 5 and a hot air gun mechanism 4. The hot air shielding mechanism 5 is located on one side of the upper spindle seat 1, and is composed of a hot air shielding mounting plate 15, a slide cylinder 16, a hot air shielding slide plate 17, a heat insulation plate 18 and a hot air shielding plate 19. The hot air shielding mounting plate 15 is fixed to one side of the upper spindle seat 1, the slide cylinder 16 is mounted on the hot air shielding mounting plate 15, the hot air shielding slide plate 17 is slidably connected with the slide cylinder 16, and the hot air shielding plate 19 is mounted on the hot air shielding slide plate 17 through the heat insulation plate 18. The slide cylinder 16 can move forward and backward to drive the hot air shielding plate 19 to be pushed out or retracted, which can effectively prevent high temperature from continuously blowing toward the mold when the winding is stopped.

[0022] The hot air gun mechanism 4 includes a hot air gun mounting plate 20, a hot air gun 21, a hot air gun head 22 and a hot air gun fixing block 23. The hot air gun mounting plate 20 is mounted on the upper spindle moving plate 9, the hot air gun 21 is fixed on the hot air gun mounting plate 20 through the hot air gun fixing block 23, and the hot air gun head 22 is located at the front end of the hot air gun 21. During the winding process, the hot air gun mechanism 4 heats the coil to make the coil viscosity meet customer requirements or prevent the wire from falling apart.

[0023] The double upper mold winding mechanism 3 is composed of an outer mold motor screw group 10, an outer mold moving plate 12, an inner mold motor screw group 11, an outer mold 13 and an inner mold 14. The outer mold motor screw group 10 is connected to the outer mold moving plate 12 below, and the inner mold motor screw group 11 is connected to the outer mold moving plate 12 to control the outer mold moving plate 12 to move up and down. The inner mold 14 is installed at the bottom of the inner mold motor screw group 11, and the outer mold 13 is sleeved outside the inner mold 14. The inner mold motor screw group 11 can accurately control the inner mold 14 to move up and down to ensure the height accuracy of the coil before the special-shaped arrangement changes, and the outer mold motor screw group 10 accurately controls the outer mold 13 to move up and down through the outer mold moving plate 12 to ensure that the height of the coil after the special-shaped arrangement changes meets the requirements.

[0024] The winding method of the copper coil special-shaped arrangement winding device is as follows: S1, the upper spindle moving mechanism 2 pushes the double upper mold winding mechanism 3 together with the hot air gun mechanism 4 to the working position, and the spindle starts to rotate slowly, and accelerates to the set speed after one circle; S2. When the coil is wound to the jumping layer where the number of turns needs to be changed, the outer mold motor screw group 10 drives the outer mold 13 to descend to a specified height, and then continues the winding operation until the coil winding is completed and enters the next round of winding process.

[0025] In step S2, according to the winding logic of the equipment, the coil arrangement direction is: winding on the lower mold from the bottom until it turns back at the upper mold, and this cycle is repeated to form a formed coil. The copper coil special-shaped arrangement winding device designed by the present invention adopts a double upper mold winding method, in which the inner mold 14 limits the initial arrangement order of the coils, and the outer mold 13 limits the number of outer end coil arrangements. Therefore, the device is only suitable for winding hollow circular coils with a reduced number of coils above the odd-numbered rows of coils.

[0026] like Figure 7As shown, taking the winding of the special-shaped coil with 12, 11, 9, 8, and 9 turns per layer as an example, starting from the lower mold, the copper wire is attached to the mold surface from bottom to top to wind the coil. When the first layer is wound to 12 turns, the inner mold 14 makes the coil just in contact, effectively preventing the wire from being scattered. After the first layer is wound, the wire arrangement mechanism winds the second layer 11 turns downward and changes the layer. At this time, the outer mold 13 descends to the specified position to ensure that the third layer is in contact with the outer mold 13 when it is wound to 9 turns. After the third layer is wound, the wire arrangement mechanism continues to wind the fourth layer 8 turns and changes the layer. The wire reaches the mold, and then the fifth layer 9 turns are wound upward to complete the winding.

[0027] like Figure 8 , Fig. 9 As shown, for the special-shaped arrangement types with the number of turns per layer being 12, 11, 12, 12, 3, 2 and 13, 12, 6, 5, etc., the winding process is similar to the above, the only difference is that the number of turns of each layer and the number of effective layers of the outer mold 13 and the inner mold 14 are different, but they all follow the principle that the inner mold 14 controls the initial arrangement and the outer mold 13 controls the subsequent specific layer arrangement.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
