Description

Technical Field

[0001] This utility model relates to the field of wired headphone testing technology, and in particular to a wired headphone production testing device. Background Technology

[0002] Wired headphone production testing refers to a series of tests conducted after the headphones are manufactured to ensure that the product quality and performance meet design standards and customer requirements. Current wired headphone production testing typically involves fixing the headphones to a test bench using clamps, and then fixing the matching headphone cable to a device that can be controlled to move left and right using clamps. However, when fixing the headphones and the headphone cable, usually only the two sides of the headphones are fixed, and the headphone cable is only fixed at one point. Because the headphone cable is soft and easily bent, and due to frequent plugging and unplugging, the headphone cable is prone to warping, which makes it difficult for the connector on the headphone cable to be accurately inserted into the headphones, which is quite inconvenient.

[0003] Therefore, it is necessary to design a wired headphone production testing device that can securely clamp the headphones and headphone cable to prevent the headphone cable connector from lifting or the headphones from shifting during testing, thus ensuring the smooth progress of the testing process. Utility Model Content

[0004] To overcome the shortcomings of existing wired headphone production testing methods that only fix the two sides of the headphones and only fix one point of the headphone cable, which often results in the headphone cable being bent due to its soft and flexible material and frequent plugging and unplugging, thus preventing the headphone cable connector from being accurately inserted into the headphone, this invention provides a wired headphone production testing device that can securely clamp the headphone and headphone cable, preventing the headphone cable connector from bending or the headphone from shifting during testing, and ensuring the smooth progress of the testing process.

[0005] The technical solution of this utility model is: a wired headphone production testing device, including a tester, a fixed frame, a unidirectional lead screw, a placement platform, a bidirectional lead screw, a sliding plate, a clamping plate, a first screw, a positioning plate, and a plug-in assembly. The fixed frame is connected to the upper left rear part of the tester. The unidirectional lead screw is rotatably connected to the middle of the fixed frame. The placement platform is threadedly connected to the unidirectional lead screw. The placement platform is slidably connected to the fixed frame. The bidirectional lead screw is rotatably connected to the middle of the placement platform. Sliding plates are threadedly connected to both the front and rear parts of the bidirectional lead screw. The sliding plates are slidably connected to the placement platform. A clamping plate is connected to the side of the sliding plates that are close to each other. The first screw is rotatably connected to the middle of each sliding plate. A positioning plate is threadedly connected to the first screw. The positioning plate is slidably connected to the adjacent sliding plate. A plug-in assembly capable of stably plugging and unplugging the headphone wire is provided on the right side of the tester.

[0006] Furthermore, the clamping plates are all equipped with anti-slip textures.

[0007] Furthermore, it also includes a knob, with a knob connected to the upper side of the one-way lead screw.

[0008] Furthermore, the insertion / removal assembly includes a mounting bracket, a motor, a rotating rod, a clamping bracket, a rotating shaft, a sliding table, a fixed seat, a fixed ring, a sliding ring, and a second screw. The mounting bracket is connected to the upper right side of the detector, and the motor is connected to the right side of the mounting bracket. A rotating disk is provided on the output shaft of the motor, and a rotating rod is rotatably connected to the rotating disk. The rotating shaft is connected to the left side of the rotating rod. A sliding table is slidably connected to the upper left side of the mounting bracket, and the sliding table is rotatably connected to the rotating shaft. A fixed seat is connected to the upper side of the sliding table, and a fixed ring is connected to the upper left side of the fixed seat. A sliding ring is slidably connected to the right side of the fixed seat. The second screw is threadedly connected to the middle of both the sliding ring and the fixed ring, and a clamping bracket is rotatably connected to the lower side of the second screw.

[0009] Furthermore, all clamping frames are arc-shaped structures.

[0010] Furthermore, a handle is provided on the upper side of each second screw.

[0011] The beneficial effects are as follows: 1. By rotating the first screw, the clamping plate moves downward under the action of the thread, so that the clamping plate contacts the upper side of the earphone. Then, by rotating the second screw, the clamping frame moves downward and contacts the left and right ends of the connector respectively, thus achieving a stable clamping of the earphone and earphone cable, avoiding the earphone cable connector from lifting or the earphone from shifting during the test, and ensuring the smooth progress of the test.

[0012] 2. This utility model uses a knob to rotate a one-way lead screw, which moves the placement platform up and down, causing the earphone to move up and down. Then, the earphone cable connector is placed between the fixed ring and the sliding ring. The sliding ring is then adjusted according to the length of the connector, which allows for adjustment of the earphone height and the position of the clamp, making it convenient for testing different models of wired earphones and providing a flexible application.

The mounting bracket 2 is connected to the upper left rear of the detector 1. The knob 3 is connected to the upper side of the one-way lead screw 4. The one-way lead screw 4 is rotatably connected to the middle of the mounting bracket 2. The placement platform 5 is threadedly connected to the one-way lead screw 4. The placement platform 5 is slidably connected to the mounting bracket 2. The middle of the placement platform 5 is rotatably connected to the knob 3. A bidirectional lead screw 6 is connected, and both the front and rear ends of the bidirectional lead screw 6 are threadedly connected to sliding plates 7. The sliding plates 7 are slidably connected to the placement platform 5. The sides of the sliding plates 7 that are close to each other are connected to clamping pieces 8. The clamping pieces 8 are provided with anti-slip textures for easy gripping. The middle of the sliding plates 7 is rotatably connected to a first screw 9. The first screw 9 is threadedly connected to a positioning plate 10. The positioning plate 10 is slidably connected to the adjacent sliding plate 7. The right side of the detector 1 is provided with a plug-in assembly.

[0020] like Figure 1 , Figure 3 and Figure 4 As shown, the insertion / removal assembly includes a mounting bracket 11, a motor 12, a rotating rod 13, a clamping bracket 14, a rotating shaft 15, a sliding table 16, a fixed base 17, a fixed ring 18, a sliding ring 19, and a second screw 20. The mounting bracket 11 is connected to the upper right side of the detector 1. The motor 12 is connected to the right side of the mounting bracket 11. A rotating disk is mounted on the output shaft of the motor 12, and the rotating rod 13 is rotatably connected to the rotating disk. The rotating shaft 15 is connected to the left side of the rotating rod 13. The upper left side of the mounting bracket 11 is slidably connected to... There is a sliding table 16, which is rotatably connected to the rotating shaft 15. A fixed seat 17 is connected to the upper side of the sliding table 16. A fixed ring 18 is connected to the upper left side of the fixed seat 17. A sliding ring 19 is slidably connected to the right side of the fixed seat 17. A second screw 20 is threadedly connected to the middle of the sliding ring 19 and the fixed ring 18. A handle is provided on the upper side of the second screw 20 for easy gripping.

[0021] When using this device, first place the tester 1 in the wired headphone production testing area, then place the headphones on the placement platform 5. Next, rotate the bidirectional lead screw 6, causing the sliding plate 7 to move under the action of the thread, so that the clamping plates 8 move closer together to clamp the front and rear sides of the headphones. Then, rotate the first screw 9, causing the locking plate 10 to move downward under the action of the thread, so that the locking plate 10 contacts the upper side of the headphones, firmly clamping the four sides of the headphones. Next, pass the headphone wire between the fixing ring 18 and the sliding ring 19, then rotate the second screw 20, causing the second screw 20 to move downward under the action of the thread, so that the clamping frame 14 contacts the left and right ends of the headphone wire connector, firmly clamping the headphone wire connector. This ensures a secure clamping of the headphones and headphone wire, preventing the headphone wire connector from lifting or the headphones from shifting during testing, ensuring a smooth testing process. After that, start the motor 12 to drive the rotating disk to rotate. The rotation of the rotating rod 13 causes the rotating shaft 15 to rotate on the sliding table 16, which in turn moves the sliding table 16 left and right on the mounting bracket 11. This allows the headphone cable connector to be repeatedly plugged and unplugged on the headphone. When different models of wired headphones have different thicknesses and therefore different plug hole positions, the knob 3 can be turned to rotate the one-way screw 4, causing the placement platform 5 to move up and down under the action of the screw, which in turn moves the headphone up and down so that the plug hole on the headphone can be aligned with the position that needs to be repeatedly plugged and unplugged. Then, the corresponding headphone cable connector is placed between the fixing ring 18 and the sliding ring 19. The sliding ring 19 is then adjusted according to the length of the connector. Finally, the second screw 20 is rotated to move the clamping bracket 14 downward to fix both ends of the connector. This allows for adjustment of the headphone height and the position of the clamping bracket 14, making it convenient to test different models of wired headphones and providing flexibility in use.
