[0002] Voice coils are a crucial component in electroacoustic equipment, and their performance directly determines the quality and lifespan of audio devices. Quality inspection of voice coils is essential for ensuring the acoustic performance and electrical stability of audio products. Therefore, voice coil quality inspection plays a vital role in the production process. However, current voice coil quality inspection methods still primarily rely on manual operation, especially in the loading and inspection stages. Manual operation is generally characterized by low efficiency, poor accuracy, and non-standard operating procedures. Manual quality inspection is not only time-consuming but also easily affected by the operator's experience and skill level, leading to inconsistencies and errors in the test results, failing to meet the high-efficiency and high-precision requirements of modern manufacturing for mass production.

[0003] As the audio product market continues to demand higher sound quality and expands production scale, manual quality inspection can no longer meet the needs of high-speed and precise production. Traditional manual material loading is not only inefficient, but also prone to deviations in the transmission, positioning, and fixing of voice coils, leading to inaccurate voice coil testing. In addition, manual operation also carries a significant risk of human error, easily overlooking unqualified voice coils or misjudging unqualified products as qualified ones, which poses a great threat to the quality control and brand reputation of audio products.

[0041] Reference Figures 1 to 7 This utility model discloses a testing machine for voice coil quality inspection, including a mounting platform 100 and a chassis 110. The chassis 110 is provided with a feeding component 200, a conveying component 300 and a quality inspection component 400. The feeding component 200 is used to pick up and deliver the voice coil to the conveying component 300. The conveying component 300 is used to drive the voice coil to move below / away from the quality inspection component 400.

[0042] The quality inspection component 400 includes a motion module 410, positive and negative terminals 420, a marker pen 430, and a microphone unit 440. The positive and negative terminals 420 and the marker pen 430 are both fixedly installed on the motion module 410. The microphone unit 440 is designed adjacent to the positive and negative terminals 420. The motion module 410 is used to drive the positive and negative terminals 420 and the marker pen 430 to move along the direction closer to / away from the voice coil.

[0044] It also includes a conveying component 500, located below the conveying component 300, for conveying the voice coil.

[0045] This utility model of a voice coil quality inspection and testing machine has significant application value in the field of automated voice coil quality inspection, and is especially suitable for quality control of large-volume voice coil production lines. The machine is designed to improve inspection efficiency and accuracy through the coordinated work of the feeding component 200, the conveying component 300, and the inspection component 400. It can comprehensively evaluate the performance of voice coils and automatically mark unqualified products, thereby ensuring that the quality of each voice coil meets the standards and avoiding the errors and inconsistencies that may occur in traditional manual inspection, thus improving quality inspection efficiency.

[0046] Specifically, the chassis 110 is a rectangular box, fixedly mounted on the mounting platform 100. The chassis 110 contains a loading assembly 200, a conveying assembly 500, a transmission assembly 300, and a quality inspection assembly 400. The loading assembly 200 is located above the conveying assembly 500 and the transmission assembly 300. The conveying assembly 500 transports the voice coil from the previous station to below the loading assembly 200. The loading assembly 200 transfers the voice coil from the conveying assembly 500 to the transmission assembly 300. The transmission assembly 300 moves the voice coil to the quality inspection area. After the voice coil reaches the quality inspection area, the motion module 410 drives the positive and negative terminals 420 to move towards the voice coil, causing the positive and negative terminals 420 to contact the contacts of the voice coil. Current is passed through the voice coil, causing it to vibrate and generate sound waves. The receiving unit 440, located beside the positive and negative terminals 420, collects these sound waves. The signal is then transmitted to the central control system. The central control system determines whether the sound wave generated by the voice coil vibration meets the preset threshold. If it does, it is considered a qualified product; otherwise, it is considered a defective product. Furthermore, the central control system transmits a signal that the voice coil is a defective product. The transmission component 300 drives the voice coil to move slightly along the direction closer to the receiving component, so that the marking pen 430 is directly above the voice coil. The motion module 410 drives the marking pen 430 to move along the direction closer to the voice coil to mark the voice coil. This achieves full automation of the voice coil from material loading to quality inspection, improving quality inspection efficiency. In this embodiment, the motion module 410 is a cylinder or a linear module that drives the positive and negative terminals 420 and the marking pen 430 to move vertically or horizontally to achieve quality inspection of the voice coil and marking of defective products.

[0047] The feeding assembly 200 includes a lateral displacement module 210 and a gripper slidably mounted on the lateral displacement module 210. The gripper is used to grip the voice coil, and the lateral displacement module 210 is used to drive the gripper to move along the direction of approaching / moving away from the conveying assembly 300.

[0048] The gripping component includes a gripping part 220 and a lifting part 230. The lifting part 230 is slidably connected to the lateral displacement module 210. The lifting part 230 is used to drive the gripping part 220 to move along the direction of approaching / moving away from the conveying assembly 500 in order to grip the voice coil.

[0049] The clamping part 220 is provided in two sets.

[0050] Specifically, the lifting unit 230 is slidably mounted on the lateral displacement module 210, and the clamping unit 220 has two sets, which can complete the feeding of two sets of voice coils in one operation. The clamping unit 220 is fixedly mounted on the lifting unit 230. The lateral displacement module 210 drives the lifting unit 230 to move, and the lifting unit 230 drives the clamping unit 220 to move in the direction of approaching or moving away from the conveying component 500, so as to clamp the voice coils on the conveying component 500. In actual working condition, the lateral displacement module 210 drives the lifting unit 230. 0, so that the gripping part 220 is positioned above the voice coil on the conveying component 500. Further, the lifting part 230 drives the gripping part 220, so that the two gripping parts 220 grip the voice coil. After the voice coil is gripped, the lateral displacement module 210 drives the lifting part 230 to move along the direction close to the conveying component 300. With the cooperation of the lifting part 230, the gripping part 220 places the voice coil on the conveying component 300, thereby completing the automated operation of voice coil feeding and improving the efficiency of voice coil feeding.

[0051] The transmission assembly 300 includes a linear motion module 310 and a transmission seat 320 slidably mounted on the linear motion module 310. The transmission seat 320 is used to place the voice coil, and the linear motion module 310 is used to drive the transmission seat 320 to move below / away from the positive and negative terminals 420 / the marker pen 430.

[0052] It also includes a material tray 900, which is used for positioning and installing the voice coil. The feeding assembly 200 places the material holder with the voice coil on its side on the conveyor seat 320.

[0053] The testing machine in this embodiment also includes a material tray 900. The conveying assembly 300 includes a linear motion module 310 and a conveying base 320. The conveying base 320 is slidably connected to the linear motion module 310. Specifically, the conveying assembly 500 conveys the voice coil through the material tray 900. The material tray 900 with the voice coil on the conveying assembly 500 is placed sideways. Therefore, when the feeding assembly 200 picks up the material tray 900 with the voice coil and delivers it to the conveying base 320, the material tray 900 is also placed sideways on the conveying base 320. The linear motion module 310 drives the movement of the conveying base 320 to move the voice coil. This design further realizes the feeding of the voice coil. In actual working condition, the material tray 900 is placed on the conveying base 320, with a first clearance area 600 and a second clearance area 700. When the voice coil is being tested, the motion module 410 drives the positive and negative terminals 420 to move downwards to abut the contact points of the voice coil. At this time, the marking pen... 430 is located within the first clearance area 600. After the inspection is completed, when the main control system transmits a signal that the voice coil is a defective product, the linear motion module 310 drives the conveyor seat 320 to move slightly along the direction close to the receiver component, so that the marker pen 430 is directly above the voice coil. Then, the motion module 410 drives the marker pen 430 to move downward, so that the marker pen 430 contacts the voice coil and marks it. At this time, the positive and negative terminals 420 are located within the second clearance area 700. The design of this embodiment, by placing the material tray 900 with the voice coil on its side on the conveyor seat 320, makes the positioning and transmission of the voice coil more stable. The side-placement design facilitates the contact between the positive and negative terminals 420 and the voice coil contacts, and the marking pen 430 marks the defective voice coil. The whole process does not require manual intervention. The automated design improves production efficiency, reduces labor costs, and reduces errors that may be caused by manual operation.

[0054] The sound acquisition area 800 of the sound receiving unit 440 is located on the same horizontal plane as the voice coil.

[0055] The sound acquisition area 800 is circular.

[0056] Based on the above embodiments, the sound receiving unit 440 is a microphone collector, and its circular sound acquisition area 800 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.

[0057] 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.
