Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ultra-thin fan, in particular to a wire distribution sleeve for an ultra-thin fan and a preparation process thereof. BACKGROUND

[0002] In the prior art, 1. There is only a longitudinal winding column in the winding sleeve, which is usually a metal conductive column. When it is welded to the circuit board, it is inserted into the hole and welded to the board below in the form of a plug-in. Or the plastic winding column is integrated with the winding sleeve. After the winding sleeve is fixed to the circuit board, the copper wire is wound to the solder pad under the board by manual distribution (usually with the aid of a jig). 2. Without a winding sleeve, manual distribution is usually required. When the copper wire is welded to the circuit board, it needs to be fixed to the position of the solder pad on the board by manual or automatic jig before welding (which requires high welding skills).

[0003] However, the two methods have the following defects: 1. The metal winding column with a winding sleeve requires a higher Z-axis space, which is not suitable for thin motors.

[0004] 2. The plastic winding sleeve with a winding sleeve requires high welding skills, and the welding quality is unstable and the production efficiency is low.

[0005] 3. Without a winding sleeve, it is not easy to distribute and has the risk of wire breakage. It requires high welding skills, and the welding quality is unstable and the production efficiency is low. SUMMARY

[0006] The purpose of the present application is to provide a wire distribution sleeve for an ultra-thin fan and a preparation process thereof to solve the problems raised in the background art.

[0007] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a wire distribution sleeve for an ultra-thin fan, comprising a motor housing, a fan blade is arranged on the outer side of the motor housing, a motor housing base is arranged at the lower end of the motor housing, a PCB board, a stator and a copper wire are arranged on the end face of the motor housing base close to the motor housing.

[0008] Further optimization, a cavity for installing the stator and copper wire is formed between the motor housing and the motor housing base.

[0009] Further optimization, an axis is arranged between the stators.

[0010] Further optimization, the stators are arranged on the outer side of the axis and arranged in the circumferential direction.

[0011] Further optimization, a limiting block is arranged between adjacent stators.

[0012] Further optimization, a horizontal wire distribution sleeve is arranged at the lower end of each stator.

[0013] Further optimized, the stator has a coating on its outer side.

[0014] Further optimization is possible, where the copper wire can be a coil or a copper coil.

[0015] A manufacturing process for a splitter sleeve for an ultra-thin fan includes the following steps: Step 1: Wear an anti-static bracelet, and wear finger cots on your thumb, index finger, and middle finger; Step 2: Organize and set up the materials to be used, and clean the area around the workbench before starting work; Step 3: Take 1 piece of coil and 1 piece of glued base; Step 4: Slide the coil onto the base tubing and gently press to secure it; Step 5: Inserting the coil into the glued tube is considered the final step and should not be removed arbitrarily. This completes the final assembly. Beneficial effects

[0016] The ultra-thin fan wire splitter sleeve and its manufacturing process provided by this invention feature a rear-entry insulating wire splitter sleeve design with a wire-locking groove design that can horizontally fix the copper wire. When the stator winding is combined with the circuit board, the copper wire head and tail are simultaneously positioned at the circuit board solder pads, allowing for direct pressure welding. This reduces the working time by at least 50%, 100% avoids wire breakage, and reduces false soldering (99% for manual welding, 100% for automatic pressure welding). Attached Figure Description

[0017] Fig. 1 This is a schematic diagram of the overall structure of the present invention; Fig. 2 This is a schematic diagram of the overall structure of the present invention without the fan and motor housing. Fig. 3 This is a cross-sectional view of the overall structure of the present invention. Detailed Implementation

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments. Example

[0019] like Figs. 1-3 As shown, a splitter sleeve for an ultra-thin fan includes a motor housing 6, a fan blade 1 on the outside of the motor housing 6, a motor housing base 10 at the lower end of the motor housing 6, and a PCB board 9, a stator 3 and copper wires 5 on the end face of the motor housing base 10 near the motor housing 6.

[0020] In this embodiment, a cavity for mounting the stator 3 and copper wire 5 is formed between the motor housing 6 and the motor housing base 10.

[0021] A shaft 4 is provided between the stators 3.

[0022] Multiple stators 3 are arranged on the outside of the shaft 4 in a circumferential direction.

[0023] Limiting blocks 11 are provided between multiple adjacent stators 3.

[0024] The lower ends of multiple stators 3 are provided with transverse branch sleeves 8.

[0025] The stator 3 has a coating on its outer side.

[0026] Copper wire 5 can be a coil or a copper coil.

[0027] A manufacturing process for a splitter sleeve for an ultra-thin fan includes the following steps: Step 1: Wear an anti-static bracelet, and wear finger cots on your thumb, index finger, and middle finger; Step 2: Organize and set up the materials to be used, and clean the area around the workbench before starting work; Step 3: Take 1 piece of coil and 1 piece of glued base; Step 4: Slide the coil onto the base tubing and gently press to secure it; Step 5: Inserting the coil into the glued tube is considered the final step and should not be removed arbitrarily. This completes the final assembly.

[0028] The rear-entry insulating wire splitter sleeve design features a wire-locking groove for horizontally fixing the copper wire. When the stator winding is combined with the circuit board, the copper wire ends are simultaneously positioned on the circuit board pads for direct pressure soldering. This facilitates wire splitting after stator winding, improves production efficiency, reduces the risk of wire breakage, and fixes the copper wire ends for easy soldering to the circuit board, avoiding poor soldering and allowing for subsequent integration into a fully automated soldering process.

[0029] It improves production efficiency, avoids poor welding, and allows for the subsequent implementation of fully automated welding processes.

[0030] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
