Description
Technical Field
[0001] This utility model relates to the field of Bluetooth headset manufacturing technology, specifically to a fixing device for testing Bluetooth headsets. Background Technology
[0002] Bluetooth headphones are audio devices that achieve wireless connectivity via Bluetooth technology. With their convenience and wireless freedom, they have become a common accessory for modern commuters, exercisers, and office workers. In terms of type, Bluetooth headphones can be divided into true wireless earbuds, over-ear Bluetooth headphones, neckband headphones, and bone conduction headphones. Before leaving the factory, Bluetooth headphones undergo rigorous testing to ensure their functionality, safety, durability, and user experience. The main testing items include Bluetooth connection testing, audio quality testing, battery life testing, and waterproof and dustproof testing. Regarding Bluetooth connection performance testing, current technology generally uses an external clamping mechanism to secure the headphones, then isolates them from the outside environment to test their Bluetooth transmission performance. However, existing clamping mechanisms lack clamping parts that conform to the outer contour of the headphones, resulting in an ineffective fit. Furthermore, the clamping force of existing mechanisms cannot be precisely controlled, posing a risk of damage to the headphones during clamping. Utility Model Content
[0003] This utility model provides a fixing device for detecting Bluetooth headsets. By setting a limiting plate on the moving block and setting a limiting groove on the limiting plate that matches the outer contour of the headset, the two limiting plates can be connected to form a fixed space for accommodating the headset. This can achieve precise positioning and clamping of the outer contour of the Bluetooth headset, solving the problem that the existing clamping mechanism cannot effectively fit with the headset body.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] A fixing device for detecting Bluetooth headsets, comprising:
[0006] Base;
[0007] A fixing mechanism is horizontally arranged along the length of the base. The fixing mechanism includes a drive component arranged on the base, two movable blocks arranged opposite to each other at the output end of the drive component and capable of moving freely in sync, and a limiting component fixed on the top of the movable blocks for fixing the earphone.
[0008] The limiting component includes two limiting disks placed on the movable block and capable of moving with the movable block to dock to form a limiting disk for accommodating the earphone, and a limiting groove formed on the limiting disk and matching the long side of the earphone.
[0009] Preferably, the drive assembly includes a drive motor fixed on the base and a bidirectional lead screw disposed at the output end of the drive motor and rotatably disposed on the base, and the moving block is disposed on the bidirectional lead screw by a lead screw nut.
[0010] Preferably, the base sidewall is provided with guide rails distributed parallel to the bidirectional lead screw, and the moving block is provided with a limiting block that matches the guide rails.
[0011] Preferably, the Bluetooth headset detection fixing device further includes a transfer mechanism disposed on the side wall of the base. The transfer mechanism includes a bracket fixed on the base, a horizontally moving cylinder disposed on the side wall of the bracket, a vertically moving cylinder disposed at the moving end of the horizontally moving cylinder, a clamping cylinder disposed at the moving end of the vertically moving cylinder, and a gripper disposed at the moving end of the clamping cylinder and capable of moving relative to each other.
[0012] Preferably, the gripper is a clamping plate made of flexible material, and the clamping surface of the clamping plate is provided with contact protrusions.
[0013] Preferably, the Bluetooth headset detection fixing device further includes a feeding mechanism disposed at the end of the transfer mechanism away from the base.

When they move towards each other to dock, the two limiting disks can dock to form a fixed space for accommodating the earphone.

Detailed Implementation
[0029] A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings.
[0030] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions: (Refer to...) Figure 1 , Figure 2 , Figure 3A fixing device for detecting Bluetooth headsets includes a base 10 and a fixing mechanism. The fixing mechanism is horizontally arranged along the length of the base 10. Further, the fixing mechanism includes a driving component, moving blocks 220, and a limiting component. The driving component, as a power source, is mounted on the base. Two moving blocks 220 are arranged opposite each other at the output end of the driving component and can move freely and synchronously. The limiting component is fixedly mounted on the top of the moving blocks and is used to fix the Bluetooth headset 50. The limiting component includes limiting discs 231 and limiting grooves 232. Two limiting discs are used, and the two limiting discs are positioned relative to the moving blocks. Correspondingly, the two moving blocks 220 are placed on the moving blocks 220. The limiting groove 232 is opened on the limiting plate and matched with the long side of the earphone. In use, the two moving blocks 220 can move towards each other or away from each other under the drive of the driving component. When they move towards each other to dock, the two limiting plates can dock to form a fixed space for accommodating the earphone. At the same time, since the limiting plate is provided with a limiting groove, the limiting groove and the limiting effect of the earphone body can be used to achieve precise positioning and clamping of the outer contour of the Bluetooth earphone. After the earphone is clamped, the fixed earphone can be isolated by an external sealing cover to facilitate the smooth testing of the subsequent Bluetooth transmission performance. This embodiment can avoid the problem that the existing clamping mechanism cannot effectively fit with the earphone body.
[0031] Furthermore, in order to improve the sealing effect of the limiting plate 231 and the limiting groove 232 on it for clamping and fixing the earphone, a sealing strip is provided at the docking position of the two limiting plates. In this way, when the two limiting plates dock to form a whole, the sealing effect of the whole limiting component can be achieved by using the connection of the sealing strips on both sides.
[0032] Reference Figure 5 It should be noted that the shapes of the limiting disk 231 and the limiting groove 232 in this embodiment can be adapted to the shape of the Bluetooth headset to be tested, and are not limited to the structure shown in the figure. That is, when the main body outline of the headset to be tested is rectangular, a limiting disk with a rectangular limiting groove can be set accordingly; and when the main body outline of the headset to be tested is cylindrical, a limiting disk with a cylindrical limiting groove can be set accordingly.
[0033] Reference Figure 4In this preferred embodiment, the driving assembly includes a drive motor 211 and a bidirectional lead screw 212. The drive motor 211 is fixedly mounted on the base 10, and the bidirectional lead screw 212 is mounted on the output end of the drive motor and rotatably mounted on the base 10. Correspondingly, the moving block 220 is mounted on the bidirectional lead screw via a lead screw nut. Since the bidirectional lead screw has two helical segments with opposite directions of rotation, when the drive motor 211 drives the bidirectional lead screw to rotate, the bidirectional lead screw drives the lead screw nut on it to move axially. The lead screw nut then drives the moving blocks on both sides to move towards or away from each other, thereby realizing the opening and closing of the limiting plate. This allows for the fixed positioning of the Bluetooth headset when the two limiting plates are engaged. Since the force used to clamp the Bluetooth headset by the limiting plate is achieved by the drive motor driving the bidirectional lead screw, the clamping force of the limiting plate on the Bluetooth headset can be precisely controlled, avoiding damage to the headset. Furthermore, in this embodiment, the clamping force on the headset can also be controlled by the drive motor according to actual production needs.
[0034] Furthermore, in order to achieve stable movement of the moving block 220 along the base 10, a guide rail 110 is provided on the side wall of the base 10, which is parallel to the bidirectional lead screw 212. Correspondingly, a limiting block 221 matching the guide rail is provided on the moving block 220. In use, the moving block is fastened to the guide rail by the limiting block. In this way, when the moving block moves along the bidirectional lead screw, it will move synchronously along the guide rail. Under the limiting action of the guide rail, a stable slider of the moving block can be obtained.
[0035] Reference Figure 6In some embodiments, the Bluetooth headset detection fixing device further includes a transfer mechanism disposed on the side wall of the base 10. The transfer mechanism includes a bracket 310, a horizontal movement cylinder 320, a vertical movement cylinder 330, a clamping cylinder 340, and grippers 350. The bracket 310 is fixedly disposed on the base 10. The horizontal movement cylinder 320 is horizontally disposed on the side wall of the bracket. The vertical movement cylinder 330 is disposed at the moving end of the horizontal movement cylinder. The clamping cylinder 340 is disposed at the moving end of the vertical movement cylinder. The grippers 350 are disposed at the moving end of the clamping cylinder. It should be noted that the clamping cylinder 340 is a dual-output cylinder; correspondingly, the grippers are configured to be fixedly disposed opposite to the two outputs of the clamping cylinder. The two grippers can move relative to each other to achieve a clamping effect. In use, the horizontal movement of the transverse cylinder and the vertical movement of the vertical cylinder move the grippers to the loading position. The opening and closing of the clamping cylinder drives the grippers to grab the Bluetooth headset to be tested. Then, the actions of the transverse, vertical, and clamping cylinders are used again to move the Bluetooth headset above the two limit plates. The opposing movements of the two limit plates then clamp the sides of the headset. After the headset is fixed, the clamping cylinder releases the gripper. Then, the actions of the transverse and vertical cylinders are used again to move the grippers away from the limit plates. The Bluetooth performance of the fixed headset can then be tested.
[0036] Furthermore, in order to protect the Bluetooth headset and prevent damage to its outer contour during clamping, the clamp 350 is a clamping plate made of flexible material, and the clamping surface of the clamping plate is provided with contact protrusions 351. In use, the Bluetooth headset can be clamped on the outside through the clamping plate with contact protrusions.
[0037] Reference Figure 7 , Figure 8 In some embodiments, the Bluetooth headset detection fixing device further includes a feeding mechanism disposed at the end of the transfer mechanism away from the base 10. The feeding mechanism includes a dropping seat 410 fixed on the base 10. The dropping seat includes a dropping frame 411, a dropping cylinder 412 and a dropping cylinder 413. The dropping frame 411 is fixed on the side wall of the base. The dropping cylinder 412 is fixedly disposed along the axis of the dropping frame. The dropping cylinder 413 is disposed at the output end of the dropping cylinder.
[0038] Furthermore, the material dropping frame 411 includes an annular body 4111 and connecting rods 4112 evenly distributed along the circumference of the annular body. That is, there are multiple connecting rods, and the multiple connecting rods form a cylindrical structure along the material dropping frame. The material dropping cylinder 412 is set at the axial position of the annular body 4111 through the connecting rods 4112. Specifically, one end of the connecting rod is fixedly set on the side wall of the annular body, and the other end of the connecting rod extends towards the axial position of the annular body and is fixedly connected to the material dropping cylinder, so as to fix the material dropping cylinder at the axial position of the annular body.
[0039] Furthermore, the feeding cylinder 413 has a cylindrical structure, and its top end is connected to the discharge port of the discharge cylinder 412. The bottom end of the feeding cylinder 413 is provided with a discharge port. At the same time, an inclined discharge surface 4131 for discharging is provided on the inner side of the feeding cylinder and at the position corresponding to the discharge port of the discharge cylinder 412. In use, after the Bluetooth headset is detected, the horizontal movement cylinder, the vertical movement cylinder, and the clamping cylinder are activated to drive the gripper to contact the outside of the headset and clamp the headset. Then, the horizontal movement cylinder and the vertical movement cylinder are activated to move the detected headset to the top of the discharge frame. As the clamping cylinder releases the headset, the headset is conveyed along the discharge cylinder and enters the feeding cylinder. It is then conveyed backward through the inclined discharge surface in the feeding cylinder and finally discharged to the outside through the discharge port at the bottom end of the feeding cylinder.
[0040] Furthermore, in order to facilitate the conveying of the tested earphones conveyed by the feeding cylinder 413, the feeding mechanism also includes a conveying mechanism 420 disposed at the output end of the dropping seat 410. Specifically, the conveying mechanism is a conveyor belt.
[0041] In use, the transverse cylinder 320, vertical cylinder 330, and clamping cylinder 340 are used to grab the Bluetooth headset to be tested from the feeding mechanism. After clamping, the headset is moved above the two side limiting plates 231 by the cooperation of the aforementioned cylinders. Then, the two side moving blocks drive the two side limiting plates to move towards each other until they contact the outer contours of the headset on both sides, so that the headset is clamped and fixed by the limiting plates and their limiting grooves. Then, the headset on the limiting plates can be isolated by an external sealing cover for Bluetooth connection performance testing. After the test is completed, the transverse cylinder 320, vertical cylinder 330, and clamping cylinder 340 are used to pick up the headset on the limiting plates, and the headset is released into the dropping seat by the cooperation of the aforementioned cylinders. The headset is conveyed backward along the dropping frame 411, dropping cylinder 412, and unloading cylinder 413, and finally conveyed out along the conveying mechanism 420.
[0042] The above-described embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model.
