Description
Technical Field
[0001] The present invention relates to the technical field of the assembly and positioning of Bluetooth headset housings, and specifically relates to a positioning device for assembling the housings of wireless Bluetooth headsets. Background Art
[0002] With the development of the times, wireless Bluetooth headsets have an increasingly high market demand due to their convenience and excellent user experience. In the production of wireless Bluetooth headsets, the assembly of the housing is a crucial link. The traditional assembly of wireless Bluetooth headset housings mainly relies on manual operation. When workers assemble, they can only align and fix the headset housing components by visual observation and the touch of both hands. In the positioning process, it is difficult to ensure that the seemingly same-sized headset housings in different batches can be positioned at an ideal position every time. This process is time-consuming and laborious, and it is even more difficult to guarantee the consistency of positioning. In the subsequent assembly process, due to inaccurate initial positioning, the headset housing may shake and displace during operation, which not only leads to a high defective rate, may seriously affect the production efficiency, but also increases the production cost.

The whole operation is simple, without the need to rely on additional tools, reducing the labor cost, and can achieve positioning for headset shells of the same size. When the headset shell is positioned and clamped, the threaded rod 301, the threaded sleeve 303 and the connecting rod 304 cooperate with each other to drive the moving plate 305 to apply a stable and uniform clamping force to the headset shell, effectively preventing the shell from shaking and displacing during the assembly process, thereby reducing the probability of defective products.
[0015] Both ends of the outer wall of the threaded rod 301 are rotatably connected to the inner wall of the main body box 1. Threaded sleeves 303 are sleeved on both ends of the rod body of the threaded rod 301. A connecting rod 304 is fixedly connected to one side of each threaded sleeve 303. One side of each connecting rod 304 is fixedly connected to the outer wall of the moving plate 305. When the threaded rod 301 rotates, it can drive the threaded sleeves 303 at both ends to move along the rod body, and then through the connecting rod 304, the moving plate 305 moves synchronously. This structure can control the moving distance and position of the moving plate 305, realize the stable clamping of the headset shell, and improve the positioning and stability during the assembly of the headset shell.
[0016] A servo motor 202 is arranged inside the protective cover 201, and one side of the worm 204 rotates with the inner wall of the main box 1. The protective cover 201 can provide protection for the servo motor 202 and extend the service life of the servo motor 202. At the same time, the servo motor 202 provides a stable and controllable power source for the device by driving the worm 204 to rotate.
[0017] Both ends of the inner wall of the connecting groove 5 are fixedly connected to the outer wall of the fixing block 401, and one side of the outer wall of the fixing block 401 is fixedly connected to the corresponding outer wall of the fixing block 401. This fixed connection method ensures the stability of the fixing block 401, so that the snap-on assembly 4 can be firmly installed on the main box 1. During the assembly process of the earphone shell, the stable fixing block 401 can ensure that the snap-on block 404 is reliably snap-on to the earphone shell.
[0018] The side of the return spring 406 away from the slide plate 405 is fixedly connected to the inner wall of the slide groove 403, and the front end of the outer wall of the threaded rod 301 is fixedly connected to the limiting ring 302. The return spring 406 ensures the clamping and positioning force of the block 404 on the earphone shell. The output end of the servo motor 202 passes through the main box 1 and is fixedly connected to the outer wall of the worm gear 204, which can ensure that the power of the servo motor 202 is transmitted to the worm gear 204, thereby driving the worm wheel 203 and the threaded rod 301 to rotate, thereby realizing the control of the movable plate 305.
[0019] Working principle: A clamping assembly 4 is provided on one side of the main box 1 of the positioning device. The clamping block 404 is manually toggled, and the clamping block 404 drives the slide plate 405 to slide in the slide groove 403 of the fixed plate 402. During this process, the slide plate 405 compresses the return spring 406. At this time, the Bluetooth headset shell to be assembled can be placed at a suitable position on the fixed plate 402. After the clamping block 404 is released, the return spring 406 rebounds, driving the slide plate 405 and the clamping block 404 to reset, thereby clamping and fixing the headset shell on the fixed plate 402. The fixed block 401 in the clamping assembly 4 is fixedly connected to the main box 1 through the connecting groove 5 to ensure the stability of the entire clamping structure. In the power assembly 2 at the rear end of the main box 1, the servo motor 202 in the protective cover 201 is on standby, the output end of the servo motor 202 passes through the main box 1 and is fixedly connected to the outer wall of the worm 204, and one side of the worm 204 is rotatably connected to the inner wall of the main box 1, preparing for the subsequent power supply; The servo motor 202 is started, and the servo motor 202 drives the worm 204 connected thereto to rotate. Since the worm 204 and the worm wheel 203 are meshed with each other, the rotation of the worm 204 causes the worm wheel 203 to rotate. The worm wheel 203 is fixedly connected to the rear end of the threaded rod 301, so the rotation of the worm wheel 203 drives the threaded rod 301 to rotate at the same time; The two ends of the outer wall of the threaded rod 301 are rotatably connected to the inner wall of the main body box 1. Threaded sleeves 303 are sleeved on both ends of its rod body. When the threaded rod 301 rotates, according to the principle of screw drive, the threaded sleeves 303 at both ends will move axially on the threaded rod 301. One side of the threaded sleeve 303 is fixedly connected to a connecting rod 304, and the other side of the connecting rod 304 is fixedly connected to the outer wall of the moving plate 305. Therefore, the movement of the threaded sleeve 303 drives the moving plate 305 to move synchronously through the connecting rod 304. The two moving plates 305 move to clamp and stabilize the earphone housing that has been clamped and fixed on the fixing plate 402.
