Description

Technical Field

[0001] This utility model relates to the field of voice coil quality inspection technology, and in particular to a device for voice coil quality inspection. Background Technology

[0002] Voice coils are essential electroacoustic components widely used in loudspeakers, headphones, microphones, and other electroacoustic devices. As a core component, the performance of the voice coil directly affects the sound quality and lifespan of the equipment. Therefore, quality control is particularly important during the manufacturing process of voice coils. The electrical properties (such as DC resistance and impedance) and acoustic properties (such as frequency response and distortion rate) of the voice coil must meet design standards to ensure excellent sound quality and stable operation in the equipment.

[0003] Currently, most voice coil quality inspection still relies on manual operation, including electrical parameter measurement and simple visual inspection. Manual inspection is slow and cannot meet the needs of large-scale production. Moreover, human factors are prone to errors, such as poor contact or improper operation, which can lead to rework in the inspection process and reduce efficiency.

[0004] Therefore, a device for voice coil quality inspection is proposed to solve the above-mentioned problems. Utility Model Content

[0036] Reference Figures 1 to 5 The present invention provides a device for quality inspection of voice coils, including an installation platform 100, and a transmission component 600 and a quality inspection component 200 installed on the installation platform 100. The transmission component 600 is used to transport the voice coil to the area below the quality inspection component 200.

[0037] The quality inspection component 200 includes a motion module 210, a quality inspection unit 220, and a sound receiving unit 230. The quality inspection unit 220 is connected to the motion module 210, and the sound receiving unit 230 is designed adjacent to the quality inspection unit 220. The quality inspection unit 220 includes positive and negative terminals 400. The motion module 210 drives the positive and negative terminals 400 to move closer to / away from the contacts of the voice coil. The sound receiving unit 230 is used to collect and receive the sound waves driven by the voice coil.

[0038] The transmission component 600 transports the voice coil under test to the working area of ​​the quality inspection component 200 in a certain order. The motion module 210 drives the positive and negative terminals 400 to contact the electrode contacts of the voice coil, providing an excitation signal to the voice coil. Under the drive of the electrical signal, the voice coil generates vibration and sound waves. The receiving unit 230 collects the sound wave signal and analyzes its frequency response, amplitude, and other parameters. Finally, the signal is sent to the central control component, which then determines whether the voice coil is qualified according to a preset threshold. This embodiment aims to solve the problem of low efficiency in traditional manual voice coil quality inspection by introducing automation. The device improves quality inspection efficiency and accuracy by combining the modular structure of the transmission component 600 and the quality inspection component 200, thus automating and increasing the efficiency of the entire quality inspection process. The automated process significantly reduces manual intervention and increases the speed of quality inspection, making it suitable for mass production scenarios. Furthermore, through standardized operation of the equipment, it reduces non-standard inspection problems caused by human factors, improving the consistency and reliability of quality inspection. In addition, in this embodiment, the motion module 210 is a cylinder or linear module that drives the quality inspection unit 220 to perform vertical or horizontal displacement to achieve quality inspection of the voice coil.

[0039] Based on the above embodiments, the quality inspection unit 220 further includes a marker pen 500, and the motion module 210 drives the marker pen 500 to move closer to / away from the voice coil;

[0040] The quality inspection unit 220 is provided with two sets;

[0041] The transmission component 600 is provided with a tray 900, which is used to place the voice coil.

[0042] This embodiment of the voice coil quality inspection device includes a tray 900 for positioning and mounting the voice coil. A transmission component 600 clamps the tray 900 with the voice coil to the inspection area. The inspection unit 220 also includes a mounting plate and a marker pen 500. Specifically, the marker pen 500 and the positive and negative terminals 400 are both fixedly mounted on the mounting plate and are designed adjacent to each other. Two sets of marker pens 500 and positive and negative terminals 400 are provided to achieve more efficient quality inspection. In this embodiment, the tray 900 is placed vertically on the transmission component 600, forming a first clearance area 700 and a second clearance area 800. In actual operation, the motion module 210 drives the positive and negative terminals 400 to contact the voice coil contacts. At this time, the marker pen 500 is located in the first clearance area 700. 0. This design prevents the marker pen 500 from mismarking. Furthermore, the receiver unit 230 transmits the sound wave signal driven by the voice coil to the main control component. The main control component determines whether the voice coil is a qualified product based on a preset threshold. When the voice coil is a qualified product, it is conveyed to the next workstation. When the voice coil is an unqualified product, the transmission component 600 drives the tray 900 to move along the direction close to the receiver unit 230, so that the voice coil is directly below the marker pen 500. The motion module 210 drives the marker pen 500 to move downward to mark the unqualified voice coil. At this time, the positive and negative terminals 400 are located in the second avoidance area 800. This design prevents the positive and negative terminals 400 from accidentally touching the voice coil and affecting the quality inspection process.

[0043] The sound acquisition area 300 of the sound receiving unit 230 is located on the same horizontal plane as the voice coil;

[0044] The sound acquisition area 300 is circular.

[0045] Based on the above embodiments, the sound receiving unit 230 is a microphone collector, and its circular sound acquisition area 300 is on the same horizontal plane as the voice coil. The same horizontal plane design ensures the microphone's ability to capture the sound waves emitted by the voice coil in the positive direction, avoiding acquisition errors caused by differences in vertical height or angular offset. Combined with the uniform acquisition characteristics of the circular area, it can more comprehensively reflect the acoustic performance of the voice coil, thereby improving the accuracy of the detection data.

[0046] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
