[0002] In the headphone manufacturing process, wire soldering is a crucial step in ensuring the performance of electrical signal transmission. In traditional operations, lacking dedicated tooling, the headphone unit is often manually held and fixed. Due to the delicate nature of headphone components and the small size of the wires, manual fixing easily leads to the following problems:

[0003] Poor positioning accuracy: The earphone unit lacks stable support and its position constantly shifts when held, resulting in large alignment errors between the lead wire and the soldering station, and fluctuations in soldering quality (such as poor soldering and short circuits), which affects the yield rate of earphones.

[0004] Low work efficiency: Manually adjusting fixed postures repeatedly consumes a lot of time and is difficult to adapt to the pace of large-scale production;

[0005] High risk of component damage: Uneven force applied by hand can easily cause physical damage to the earphone unit shell and internal precision structure, increasing defective costs. Therefore, we need to provide a fixture for fixing the lead wire. Utility Model Content

[0024] 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.

[0025] Please see Figure 1-7 This utility model provides a technical solution: a fixed lead wire fixture, comprising:

[0026] The device includes an earphone unit 1, a base 2, an opening slot 3, a groove 4, and a top mount 5. The base 2 has a groove 4 for placing the earphone unit 1. The top mount 5 is fixedly installed on the top of the base 2. The base 2 has an opening slot 3, which is connected to the groove 4. The opening slot 3 is used for placing the lead wire 7 inside the earphone unit 1.

[0027] The headphone unit 1 includes a base 11, an upper plate 12 and a metal plate 13. The upper plate 12 is fixed to the top of the base 11 and is used in conjunction with the groove 4. The metal plate 13 is installed on the top of the base 11 and is located at the bottom of the opening groove 3.

[0028] Specifically, a groove 4 is provided in the base 2 for placing the earphone unit 1. An opening slot 3 is connected to one side of the groove 4 for placing the lead wire 7. A top seat 5 is provided to limit the position of the earphone unit 1. The groove 4 in the base 2 is adapted to the shape of the earphone unit 1, enabling precise positioning of the earphone unit 1 and ensuring consistent positioning each time it is placed. Simultaneously, the opening slot 3 is specifically for placing the lead wire 7, allowing it to be accurately guided to the appropriate position. This provides a precise operating reference for subsequent soldering, effectively reducing problems such as incomplete soldering and mis-soldering caused by positional deviations, greatly improving soldering quality, and thus increasing the yield rate of earphone products. The earphone unit 1 is placed directly in the groove 4, the lead wire 7 is placed in the opening slot 3, and then the top seat 5 quickly completes the limiting and fixing process. The operation is simple and quick, requiring no complex adjustment process, significantly shortening the fixing time of a single earphone unit 1, accelerating the production cycle, improving overall production efficiency, and meeting the needs of large-scale production.

[0029] The width of the opening groove 3 is 2-3mm and the depth is 1.5-2mm. The inner sidewall of the opening groove 3 is set as an arc transition structure. The connection between the opening groove 3 and the groove 4 is provided with a 45-degree chamfer with a chamfer length of 0.8-1mm. This structure provides a directional constraint channel for the lead wire 7 and avoids the lead wire 7 from being scratched by sharp edges during placement.

[0030] A recessed groove 6 is provided at the edge of the chassis 11. The recessed groove 6 is located on one side of the metal sheet 13. Two lead wires 7 are installed in the base 2. Both lead wires 7 are located in the recessed groove 6.

[0031] It is worth noting that the depth of the recessed groove 6 is 0.8-1.2mm, and the width is 0.3-0.5mm larger than the diameter of the lead wire 7. The two ends of the recessed groove 6 extend to the edge of the chassis 11 to form a flared structure with an opening angle of 60 degrees. The two lead wires 7 are arranged in parallel in the recessed groove 6 with a spacing of 1-1.5mm. The physical isolation of the recessed groove 6 prevents the lead wires 7 from tangling with each other and ensures electrical insulation during welding.

[0032] Two conical seats 8 are fixedly installed on the surface of the top seat 5. The conical seats 8 are used for the winding and placement of the movable end of the lead wire 7, and the conical seats 8 are set as adhesive layer seats.

[0033] It should be noted that the conical seat 8 is made of anti-static silicone material with a surface resistance of 10. 6 -10 9 Ω achieves the winding and positioning of lead wire 7 through a conical structure, and avoids damage to the electronic components of headphone unit 1 by static electricity through anti-static properties.

[0034] A ring-shaped cotton layer 9 is fixedly installed at the bottom of the top seat 5;

[0035] Furthermore, the annular cotton layer 9 at the bottom of the top seat 5 is made of polyester fiber cotton with a density of 30-50. The inner diameter of the annular cotton layer 9 is adapted to the outer diameter of the upper plate 12 of the earphone unit 1, and the thickness of the annular cotton layer 9 is 1-2mm. After the top seat 5 is fixed to the base 2, the annular cotton layer 9 forms a surface contact with the top surface of the upper plate 12 of the earphone unit 1, and generates a preload force of 0.3-0.5N through compression deformation, which not only restricts the axial displacement of the earphone unit 1, but also reduces the assembly impact through buffering.

[0036] The upper surface of the metal sheet 13 forms a height difference of 0.5-1mm with the bottom surface of the opening groove 3, and the edge of the metal sheet 13 maintains a gap of 0.8-1mm with the inner wall of the opening groove 3. This structure allows the welding tool to make vertical contact with the metal sheet 13 from above the opening groove 3, avoiding interference with the base 2, and ensuring that the heat during welding is not quickly conducted through the base 2 and affects the welding quality.

[0037] A rubber sleeve 10 is fixedly installed on the inner wall of the groove 4;

[0038] The inner wall of the groove 4 is covered with silicone material with a Shore hardness of 50-60. The thickness of the silicone sleeve 10 is 0.5-1mm. The inner wall of the silicone sleeve 10 and the outer wall of the upper plate 12 of the earphone unit 1 form an interference fit with an interference amount of 0.1-0.2mm. The silicone sleeve 10 is fixedly connected to the inner wall of the groove 4 with food-grade adhesive, which not only achieves tight clamping of the earphone unit 1 through elastic deformation, but also avoids surface scratches caused by rigid contact.

[0039] The earphone unit 1 involved in this application is implemented using existing mature technology and is connected to an external PLC controller and power supply. This is a conventional technical means in this field, so its specific circuit connection, control logic and working process will not be described in detail.

[0040] The base 2 and the top seat 5 of this device are fixedly connected. The base 2 has a groove 4 for storing the upper plate 12, which facilitates the installation of the earphone unit 1. It also has an opening groove 3 to facilitate the placement of the metal piece 13 in the earphone unit 1 and the placement of the lead wire 7. The groove 4 has an adhesive sleeve 10. The bottom of the top seat 5 has an annular cotton layer 9 to protect the surface of the earphone unit 1 and reduce scratches when placing it. The top seat 5 has two conical seats 8 for winding and storing the movable end of the lead wire 7, which facilitates the subsequent soldering of the lead wire 7 to the metal piece 13.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
