Description

Technical Field

[0001] This utility model relates to the field of magnetization device technology, and in particular to an automatic feeding mechanism for an earphone magnetization device. Background Technology

[0002] Headphones are audio devices that convert electrical signals into sound signals. They are widely used in communication, entertainment, and office settings. One of their core components is the magnet, which is usually made of high-performance permanent magnet materials such as neodymium iron boron. The magnet works in conjunction with the voice coil and diaphragm in the headphones. Through the action of electric current, it generates electromagnetic force, which drives the diaphragm to vibrate and produce sound. The magnetic properties of the magnet directly affect the sound quality of the headphones, such as sensitivity, frequency response range, and distortion rate. Therefore, a high-quality magnet is an important guarantee for high-quality headphones.

[0003] A magnet magnetizing device is a device used to magnetize permanent magnets to the desired magnetic properties. It is widely used in motors, sensors, magnetic components and other fields. The device mainly consists of a placement platform, a magnetizing chamber, a magnetizing power supply, a magnetizing coil and a control system. The magnetizing power supply provides a high-voltage pulse current, which generates a strong magnetic field through the magnetizing coil. The control system is used to adjust the magnetizing current and time to achieve precise control. The overall structure is compact, with high magnetizing efficiency and stable performance.

[0004] Existing magnet magnetization devices have advantages such as high magnetic field strength, fast magnetization speed, low energy consumption, and high control precision. However, in actual use, it is still necessary to manually place the box containing the magnet on the magnetization platform and manually remove it after magnetization is completed. This process not only increases the labor intensity of workers but also reduces the automation level and overall work efficiency of the device. Therefore, an automatic feeding mechanism for headphone magnetization devices is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic feeding mechanism for an earphone magnetizing device, which aims to improve the problem of increased labor intensity and reduced overall work efficiency caused by the manual feeding method of placing the housing on the magnetizing table in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic feeding mechanism for an earphone charging device includes a worktable. A rotary feeding assembly is installed inside the worktable. A rotary feeding plate is positioned on top of the rotary feeding assembly, and a receiving box is located inside the rotary feeding plate. A cylinder is mounted on top of the worktable, and a movable shell is fixedly connected to the output end of the cylinder. A buffer assembly is installed inside the movable shell, and a pressure plate is positioned at the bottom of the buffer assembly. A charging platform is located inside the worktable. The rotary feeding assembly includes a support frame, which is fixedly connected inside the worktable. The rotary feeding plate is rotatably connected to the top of the support frame. A driven wheel is fixedly connected to the bottom of the rotary feeding plate, and a driving wheel is located at the bottom of the rotary feeding plate. A drive column and a limit wheel are fixedly connected to the bottom of the driving wheel, and the drive column is slidably connected inside the driven wheel.

[0008] As a further description of the above technical solution:

[0009] A motor is installed inside the support frame, and the drive wheel is fixedly connected to the output end of the motor.

[0010] As a further description of the above technical solution:

[0011] The buffer assembly includes a connecting frame, which is fixedly connected to the inside of the movable shell. A movable block is slidably connected to the outside of the connecting frame. A connecting rod is rotatably connected to the bottom of the movable block. The connecting rod is rotatably connected to the top of the lower pressure plate.

[0012] As a further description of the above technical solution:

[0013] A buffer spring is fitted around the outer periphery of the connecting frame, and the buffer spring is disposed on the side of the moving block;

[0014] As a further description of the above technical solution:

[0015] A telescopic rod is fixedly connected to the bottom of the movable shell, and the end of the telescopic rod is fixedly connected to the top of the lower pressure plate.

[0016] As a further description of the above technical solution:

[0017] A guide post is fixedly connected to the top of the movable shell, and the guide post is slidably connected inside the worktable.

[0018] As a further description of the above technical solution:

[0019] The driven wheel has a slot inside, and the drive column is slidably connected inside the slot.

[0020] As a further description of the above technical solution:

[0021] The bottom of the rotating feed plate has a limiting groove, and the support frame is slidably connected inside the limiting groove.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the motor drives the drive wheel to rotate, and the drive column and the driven wheel work together to make the driven wheel rotate, which drives the rotating feed plate and the receiving box to rotate synchronously. When the receiving box rotates to the top of the magnetization table, the drive column is controlled to automatically disengage from the driven wheel, and the limit wheel precisely limits the rotating feed plate to stop it at the designated position. Then, the lower pressure plate moves down and works with the magnetization table to accurately feed the receiving box into the magnetization chamber to complete the magnetization operation. The linkage between the above structures realizes the automatic feeding process of the magnetization station, reduces manual intervention, and improves the magnetization efficiency and the automation level of the device.

[0024] 2. In this utility model, during the process of the receiving box being fed into the magnetization chamber by the lower pressure plate, the lower pressure plate applies pressure to the receiving box, and at the same time, the pressure is transmitted to the moving block installed on the connecting frame through the connecting rod, causing the moving block to slide on the connecting frame and compress the buffer spring set on the side of the moving block. This structure forms an effective buffering mechanism through the linkage of the lower pressure plate, connecting rod, moving block and buffer spring. While ensuring that the receiving box is pressed down and positioned smoothly, it effectively absorbs the instantaneous impact force, prevents the receiving box and its internal magnets from being damaged by mechanical impact, and improves the safety and stability of the device during operation.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-4 This utility model provides an embodiment of an automatic feeding mechanism for an earphone magnetizing device, comprising a workbench 1, a rotary feeding assembly installed inside the workbench 1, a magnetizing chamber, a magnetizing power supply, a magnetizing coil, and a control system disposed within the workbench 1, a rotary feeding plate 2 disposed on the top of the rotary feeding assembly, a receiving box 3 disposed inside the rotary feeding plate 2, magnets being placed in the receiving box 3, a cylinder 4 disposed on the top of the workbench 1, and a pneumatic actuator disposed on the top of the workbench 1, cooperating with the cylinder 4, a movable shell 5 fixedly connected to the output end of the cylinder 4, a buffer assembly disposed inside the movable shell 5, a pressure plate 6 disposed at the bottom of the buffer assembly, and a magnetizing table 7 disposed inside the workbench 1; the rotary feeding assembly includes... The system includes a support frame 8, which is fixedly connected inside the workbench 1. A rotary feed plate 2 is rotatably connected to the top of the support frame 8, and the support frame 8 supports the rotary feed plate 2 to rotate. A driven wheel 9 is fixedly connected to the bottom of the rotary feed plate 2, and the driven wheel 9 rotates the rotary feed plate 2. A drive wheel 10 is provided at the bottom of the rotary feed plate 2, and a drive column 11 and a limit wheel 12 are fixedly connected to the bottom of the drive wheel 10. Rotating the drive wheel 10 causes the drive column 11 and the limit wheel 12 to rotate. The drive column 11 is slidably connected inside the driven wheel 9. When the drive column 11 slides into the driven wheel 9, it pushes the driven wheel 9 to rotate. When the drive column 11 slides out of the driven wheel 9, the driven wheel 9 stops rotating through the cooperation of the limit wheel 12. The support frame 8 is equipped with a motor 13. The drive wheel 10 is fixedly connected to the output end of the motor 13. The rotation of the motor 13 is adjusted so that the time for the drive column 11 to leave the driven wheel 9 and then enter the driven wheel 9 is greater than or equal to the time for magnetizing the container 3. This allows the container 3 to rotate automatically to unload material after being magnetized, and at the same time, the next container 3 is automatically fed.

[0035] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 The buffer assembly includes a connecting frame 16, which is fixedly connected inside the movable housing 5 and connects various structures. A movable block 17 is slidably connected to the outer side of the connecting frame 16, and a connecting rod 18 is rotatably connected to the bottom of the movable block 17. The connecting rod 18 is rotatably connected to the top of the lower pressure plate 6. When the lower pressure plate 6 is subjected to force and moves upward, the pressure is transmitted to the movable block 17 through the connecting rod 18, causing the movable block 17 to slide on the connecting frame 16. A buffer spring 19 is sleeved on the outer periphery of the connecting frame 16 and is located on the side of the movable block 17. The movable block 17 slides and compresses the buffer spring 19. Through the cooperation between the movable block 17 and the buffer spring 19, the instantaneous pressure of the lower pressure plate 6 pressing down is relieved. A telescopic rod 20 is fixedly connected to the bottom of the movable housing 5, and the end of the telescopic rod 20 is fixedly connected to the top of the lower pressure plate 6. The telescopic rod 20 supports the movement trajectory of the lower pressure plate 6.

[0036] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 A guide post 21 is fixedly connected to the top of the movable shell 5. The guide post 21 is slidably connected inside the worktable 1 and slides inside the worktable 1, limiting the movement trajectory of the movable shell 5. A slot 14 is provided inside the driven wheel 9, and the drive post 11 is slidably connected inside the slot 14. By providing the slot 14, more space is provided for the drive post 11 to enter the driven wheel 9. A limiting slot 15 is provided at the bottom of the rotary feed plate 2, and the support frame 8 is slidably connected inside the limiting slot 15. By providing the limiting slot 15, the rotation trajectory of the rotary feed plate 2 is limited.

[0037] Working principle: The container 3 containing the magnet is placed into the rotating feed plate 2. When the motor 13 drives the drive wheel 10, it controls the drive column 11 to slide into the driven wheel 9, pushing the driven wheel 9 to rotate. The rotating driven wheel 9 carries the rotating feed plate 2 and the container 3 to rotate, so that the container 3 is placed on the magnetizing table 7. At this time, the motor 13 controls the drive column 11 to slide out of the driven wheel 9, and through the cooperation of the limit wheel 12, the rotating feed plate 2 stops rotating. Then, the lower pressure plate 6 cooperates with the magnetizing table 7 to send the container 3 into the magnetizing chamber inside the worktable 1 for magnetization, realizing the automatic feeding function and improving the automation level and working efficiency of the device.

[0038] When the pressure plate 6 presses down and sends the container 3 into the magnetizing chamber in the worktable 1, the instantaneous pressure generated by the pressure plate 6 contacting the container 3 is transmitted to the moving block 17 through the connecting rod 18, causing the moving block 17 to slide on the connecting frame 16 under force. The sliding moving block 17 compresses the buffer spring 19. Through the cooperation between the moving block 17 and the buffer spring 19, the pressure on the moving block 17 is relieved, and the instantaneous pressure generated by the pressure plate 6 is too large, which may cause damage to the container 3.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
