Technical Field

[0001] This utility model relates to the field of fixture technology for auxiliary welding of headphones, specifically a disassembly-type auxiliary positioning welding fixture. Background Technology

[0002] In the production of precision electronic products such as headphones, the welding accuracy of the tail components directly affects the product's performance and lifespan. To achieve high-precision welding, fixtures are needed to accurately position and securely fix the components.

[0003] In the existing technology, the positioning structure design of many welding fixtures is not precise enough, the fitting gap is large, and there is a lack of effective error prevention mechanism, which makes the components prone to displacement or misalignment during the welding process, seriously leading to a decline in welding quality. In addition, traditional welding methods are prone to poor welding quality and complex welding process, i.e. welding is prone to errors. To address this, we propose a disassembly-and-assemble auxiliary positioning welding fixture. Utility Model Content

[0026] Working principle: Following the diagram, correctly install the disassembly-type auxiliary positioning welding fixture. Place the earphone tail assembly sequentially into the slot 14 of the base 11. Magnetically attach the cover plate 12 to the top of the base 11, and then magnetically attach the side plate 13 to the side wall of the base 11, thus fixing the position of the earphone tail assembly inside the slot 14. At this point, the fixture assembly 3, composed of the base 11, cover plate 12, and side plate 13, may have gaps. Therefore, place the fixture assembly 3, which holds the earphone tail assembly, on the pre-clamping device 2. The operator controls the rubber output push plate 7 of the electric cylinder 6 to clamp the fixture assembly 3. After clamping, place the fixture assembly 3 squarely on top of the welding support plate 4. The positioning angled bracket 8, positioning straight bracket 23, and positioning post 10 on the top of the welding support plate 1 4 are used for positioning. The angle 9 of the positioning angled bracket 8 ensures that the clamp assembly 3 can only be properly engaged on the top of the welding support plate 1 4 and cannot be engaged in reverse. After welding by external equipment, the clamp assembly 3 is engaged in reverse on the top of the welding support plate 2 5. Since the welding support plate 1 4 and the welding support plate 2 5 are axially symmetrical, the top of the welding support plate 2 5 can only support the clamp assembly 3 in reverse engagement, ensuring the uniqueness of the welding, preventing welding errors, and ensuring the overall welding quality and precision. After welding is completed, the various parts of the clamp assembly 3 can be disassembled to remove the internally welded earphone tail assembly.
