Description

Technical Field

[0001] This utility model relates to the field of testing fixture technology, and in particular to a testing fixture for the touch function of headphones. Background Technology

[0002] With the rapid development of wireless communication technology, Bluetooth headsets, as portable audio devices, have been widely used in daily life and professional fields. In recent years, Bluetooth headsets have generally integrated touch control functionality, allowing users to adjust volume, control playback, and answer calls by touching the headset surface. To ensure the sensitivity and reliability of the touch control function, the touch area of ​​each headset must be functionally tested during the production process.

[0003] Traditional testing methods rely on manual operation, where workers manually touch designated areas of the headset according to preset touch commands (such as single click, double click, swipe, etc.) and judge whether the touch function is normal by observing the headset's response or the feedback from the connected device. However, this method has significant drawbacks: First, it is difficult to maintain consistent touch pressure, position, and speed during manual operation, which can easily lead to biased test results; second, prolonged repetitive work can easily cause worker fatigue, further reducing the accuracy and efficiency of testing; third, as production scales up, labor costs rise year by year, and manual testing is difficult to meet the high-efficiency quality inspection requirements of large-volume products.

[0004] To address these issues, some manufacturers have attempted to introduce robotic arms to replace manual touch controls. However, Bluetooth headsets typically employ lightweight designs, and the mechanical strength of their shell materials (such as plastic, metal, or composite materials) is limited. If touch controls are performed directly by robotic arms, the rigid contact may cause indentations on the headset surface, damage to internal components, or even structural deformation due to overload or positioning errors, thereby increasing the product defect rate.

[0005] Therefore, there is an urgent need to design a touch testing fixture specifically for Bluetooth headsets that can work in conjunction with a robotic arm to ensure accurate reproduction of touch actions while avoiding physical damage to the Bluetooth headset from mechanical contact, thereby achieving efficient, low-cost, and highly consistent automated testing operations.

[0006] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0071] 4. Test Feedback and Reset

[0072] Signal Acquisition and Judgment: During the test, the headphone touch response signal is transmitted to an external testing device (such as a PC or tester) via wired / wireless connection to determine whether the touch function is normal.

[0073] 5. Release the headphones

[0074] Open the cap: After the test is completed, rotate the cap assembly 2 to the open position away from the headphones to release the headphones under test from the lock.

[0075] Remove the earphones: Manually or by means of a robotic arm, remove the tested earphones from the earphone positioning slot 101 and send them to the next process (such as packaging or re-inspection).

[0076] Therefore, the headphone touch function testing fixture provided by this utility model can assist in completing the headphone touch function test. While ensuring accurate reproduction of touch actions, it avoids physical damage to Bluetooth headphones caused by mechanical contact, thereby achieving efficient, low-cost, and highly consistent automated testing operations.

[0077] In this embodiment, the floating touch component 3 includes:

[0078] A floating top plate 301 is located above the cap assembly 2 and is slidably disposed up and down relative to the cap assembly 2.

[0079] A flexible touch unit 302 is fixed to the bottom surface of the floating top plate 301 and is positioned directly opposite the touch area; wherein, the screw cap assembly 2 is provided with an avoidance window 2011 for the flexible touch unit 302 to pass through, corresponding to the position of the flexible touch unit 302.

[0080] A top plate spring 303 is located between the floating top plate 301 and the screw cap assembly 2, and is used to drive the floating top plate 301 to slide upward relative to the screw cap assembly 2 so that the flexible touch unit 302 is disengaged from the touch area.

[0081] The top plate spring 303 of the floating touch component 3 automatically resets the flexible touch unit 302 when not in operation, avoiding long-term pressure on the earphone from rigid contact; the spring buffer combined with the flexible touch unit 302 can dynamically adjust the touch pressure, simulating the smooth touch of a human hand, preventing rigid impact from causing indentations on the shell of the earphone under test or damage to internal components, while ensuring the accuracy and consistency of touch actions.

[0082] Optional, see Figure 3 The flexible touch unit 302 includes a metal base 3021 fixed to the bottom surface of the floating top plate 301, and a flexible contouring block 3022 detachably installed on the bottom surface of the metal base 3021.

[0083] By combining the metal base 3021 with the detachable flexible contouring block 3022, the mechanical strength of the touch unit is ensured, and the contouring block can be quickly replaced for different headphone models, which significantly improves the compatibility and testing efficiency of the fixture and reduces the hardware cost of testing multiple models.

[0084] Furthermore, the metal base 3021 is provided with a base insertion hole, and the top surface of the flexible contouring block 3022 is provided with an insertion boss that is interference-fitted and plugged into the base insertion hole.

[0085] The interference fit design of the base socket and the plug boss enables the stable installation and quick replacement of the flexible contour pressure block 3022, avoiding loosening or displacement of the pressure block during testing; the modular design simplifies the maintenance process, facilitates cleaning or replacement of worn parts, and extends the service life of the fixture.

[0086] Optionally, the flexible contouring block 3022 is made of conductive silicone. The flexible contouring block 3022 made of conductive silicone can accurately simulate the capacitive signal characteristics of a human finger, ensuring that touch commands are correctly recognized by the headphones; its softness avoids scratching the headphone surface, balancing testing accuracy and product protection, and is particularly suitable for verifying high-sensitivity capacitive touch solutions.

[0087] In this embodiment, the capping assembly 2 includes:

[0088] A rotating cover plate 201 is hinged to the fixture base 1.

[0089] A plurality of earphone pressing blocks 202 are provided, each of which is detachably mounted on the bottom surface of the rotating cover plate 201 and is used to press down on the non-touch area of ​​the top surface of the earphone to be tested.

[0090] The detachable headphone clamp 202 can be customized according to the shape of the headphone, pressing only the non-touch area (such as the edge of the headphone or the shell) to avoid accidental touch or obstruction during touch testing; the split design makes it easy to adapt to multiple headphone models, while dispersing the clamping pressure to prevent local stress concentration from causing headphone deformation.

[0091] Furthermore, an upwardly protruding support boss 102 is fixedly provided at the edge of the fixture base 1; the support boss 102 is used to abut against the bottom surface of the cap assembly 2 in the closed state to provide upward support to the cap assembly 2.

[0092] When closed, the support boss 102 provides rigid support for the cap assembly 2, limiting excessive downward pressure and ensuring uniform and controllable clamping force. This structure enhances the overall stability of the fixture, prevents the cap from deforming due to external forces, thus affecting the positioning accuracy of the earphone and extending the service life of the fixture.

[0093] Optionally, the top surface of the supporting boss 102 is provided with a plurality of closing magnets 103 for magnetically connecting with the cap assembly 2. The closing magnets 103 achieve quick locking and releasing of the cap assembly 2 through magnetic attraction, reducing the wear problem of traditional mechanical buckles; the magnetic closing operation is convenient and noiseless, suitable for high-frequency testing scenarios, while avoiding accidental opening due to accidental touch, thus improving testing safety.

[0094] In this embodiment, the fixture base 1 is provided with a test probe 104; one end of the test probe 104 is used to electrically connect to an external testing device; the other end of the test probe 104 extends into the earphone positioning slot 101 and is used to electrically connect to the test terminal of the earphone under test, so as to realize the communication connection between the earphone under test and the external testing device.

[0095] The built-in test probe 104 automatically establishes an electrical connection with the headphone test terminal when the headphone is placed in the positioning slot, eliminating the need for manual cable plugging and unplugging and achieving high-speed and stable transmission of test signals; the integrated design reduces external interference, improves test efficiency and data accuracy, and supports automated assembly line operations.

[0096] The headphone touch function testing fixture provided in this embodiment has the following advantages:

[0097] ① Floating touch component 3 spring reset: The top plate spring 303 drives the floating top plate 301 to automatically reset, and the flexible touch unit 302 dynamically adjusts the pressure to simulate the touch of a human hand, avoid rigid pressure damage to the headphones and ensure touch consistency.

[0098] ② Metal base 3021 and detachable flexible contouring block 3022: The combination design of metal base 3021 and detachable flexible contouring block 3022 improves the mechanical strength of the touch unit, while adapting to multiple models of headphones and reducing hardware costs.

[0099] ③ Detachable split earphone clamp 202: The detachable clamp presses the non-touch area of ​​the earphone to prevent accidental touch or obstruction, is compatible with multiple models and disperses the clamping pressure to prevent deformation.

[0100] It should be noted that the linear drive mechanism mentioned in this utility model can be a cylinder, hydraulic cylinder, electric cylinder, or motor lead screw linear module, etc., and the rotary drive mechanism mentioned can be a brushed motor, brushless motor, or rotary cylinder, etc. This utility model does not limit the specific structural form of the linear drive mechanism and the rotary drive mechanism.
