[0017] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0018] Please refer to Figures 1 to 4 A universal positioning test fixture for speaker modules includes a base 1, two sets of adjustable positioning components 3, and multiple abutment components 4. The base 1 has a receiving groove 11, which contains two positioning slides 12 and multiple abutment slides 13 arranged side by side. The abutment slides 13 are located between the two positioning slides 12. The two sets of adjustable positioning components 3 are respectively located at the two positioning slides 12. Each adjustable positioning component 3 includes a positioning block 31 that can slide along the positioning slide 12 and a locking screw for locking the positioning block 31 to the base 1. One end of the positioning block 31 extends into the receiving groove 11. Each abutment slide 13 is correspondingly provided with an abutment component 4. The abutment component 4 includes a reset member 42 and an abutment block 41. The abutment block 41 is slidably disposed in the abutment slide 13 and one end extends into the receiving groove 11. The reset member 42 connects the abutment block 41 to the base 1.
[0019] As can be seen from the above description, the beneficial effects of this utility model are as follows: The base 1 of this positioning test fixture has a novel structure. Through the synergistic effect of the adjustable positioning component 3 and the abutment component 4, it can assist in the universal positioning test of multiple different models of speaker modules. There is no need to design and manufacture positioning test fixtures separately for each model of speaker module, thereby significantly reducing the number of positioning test fixtures and reducing manufacturing and storage costs. Among them, the adjustable positioning component 3 can adapt to the positioning part position and size of different speaker modules by sliding the positioning block 31 in the positioning slide groove 12 and fixing it with the locking screw. The abutment component 4 effectively abuts the edge of the speaker module by sliding the abutment block 41 driven by the reset component 42 in the abutment slide groove 13, further enhancing the stability and reliability of positioning, ensuring the positional accuracy of the speaker module during the test, avoiding test errors caused by inaccurate positioning, thereby improving the accuracy and consistency of test results and providing a strong guarantee for the quality control of speaker modules.
[0020] Furthermore, one side of the receiving groove 11 is connected to the first outer wall surface 15 of the base 1, and the reset member 42 drives the abutment block 41 to move toward the first outer wall surface 15.
[0021] As described above, the first outer wall surface 15 of the base 1 is used to dock with the mounting plate with the sound outlet, ensuring that the speaker module in the receiving groove 11 can dock with the sound outlet on the mounting plate through the notch on the first outer wall surface 15.
[0022] Furthermore, the reset element 42 is a spring, a rubber block, or a spring sheet.
[0023] As can be seen from the above description, the reset component 42 can be directly replaced by a standard elastic element without the need for custom-made special parts, which helps to reduce procurement and maintenance costs.
[0024] Furthermore, the base 1 has a plurality of locking screw holes 16 arranged along the length direction of the positioning slide groove 12, the positioning block 31 is provided with a through hole, and one end of the locking screw passes through the through hole and is threadedly connected to the locking screw hole 16.
[0025] As described above, the base 1 has multiple locking screw holes 16 arranged along the length of the positioning groove 12. The through hole of the positioning block 31 can be threadedly connected to any of the locking screw holes 16, which ensures that the positioning block 31 is continuously adjustable within a large range and provides reliable mechanical locking through the discrete screw holes.
[0026] Furthermore, the adjustable positioning component 3 also includes an elastic element 32, which connects the base 1 and the positioning block 31.
[0027] Furthermore, the abutment block 41 is provided with a slotted hole 411, the long axis of the slotted hole 411 being consistent with the sliding direction of the abutment block 41; the abutment assembly 4 also includes a positioning screw, one end of which passes through the slotted hole 411 and connects to the base 1.
[0028] As described above, after confirming the approximate position of the contact block 41 on the base 1, the positioning screws are installed so that the contact block 41 can slide within a small range, thereby allowing the speaker module to be flexibly clamped, making it convenient for testers to pick up and put down the speaker module to be tested.
[0029] Furthermore, the base 1 has a plurality of positioning screw holes 17 arranged along the length direction of the abutment groove 13, and one end of the positioning screw passes through the slotted hole 411 and is threadedly connected to the positioning screw hole 17.
[0030] As described above, the base 1 is provided with multiple positioning screw holes 17 along the length of the contact groove 13. The positioning screw can be selected to fix one of them, so that the contact block 41 has a "multi-level suspension" function: when replacing speaker modules of different widths, the contact block 41 can be fixed in the most suitable positioning screw hole 17 in advance, and then the reset part 42 can provide the final clamping force, which retains the advantage of quick clamping and reduces the clamping empty stroke caused by the ineffective stroke of the contact block 41.
[0031] Furthermore, it also includes a pressure plate 2 corresponding to the receiving groove 11. One end of the pressure plate 2 is rotatably connected to the base 1, and the other end of the pressure plate 2 is provided with a first magnetic suction member 21. The base 1 is provided with a second magnetic suction member 14 that magnetically engages with the first magnetic suction member 21.
[0032] Furthermore, the pressure plate 2 is provided with a test probe 22, one end of which extends into the receiving groove 11.
[0033] As described above, the pressure plate 2 integrates test probes 22. The probes automatically align with the speaker module solder pads as the pressure plate 2 flips, realizing a linkage test that powers on immediately upon closing the cover. This eliminates the need for additional wiring steps, removes manual wiring errors and poor contact, and shortens the test cycle.
[0034] Furthermore, it also includes a quick-release elbow clamp 5 disposed on the base 1, the quick-release elbow clamp 5 being used to press against the pressure plate 2.
[0035] As described above, the base 1 is equipped with a quick-release elbow clamp 5, which applies additional vertical pressure to the pressure plate 2, forming a two-stage clamping system of magnetic initial positioning and elbow clamp final pressing.
