[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0036] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0039] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0040] In one embodiment of this utility model, such as Figure 1-5As shown, an airtightness testing device for an audio device is provided, including: a worktable 1, an airtightness testing component 2, and a positioning clamping component 3. The airtightness testing component 2, disposed on the worktable 1, includes an inflation component 201 and a pressure sensor. The inflation component 201 is used to inflate gas into the audio device, and the pressure sensor is used to detect pressure changes inside the audio device to determine its airtightness performance. The positioning clamping component 3, disposed on the worktable 1, is used to fix the audio device to be tested.

[0041] The audio equipment provided by this utility model, by setting up an airtightness testing component 2 and a positioning clamping component 3 in cooperation, can quickly and stably clamp and fix audio products and complete the airtightness test. The inflation component 201 inflates gas into the audio, and the pressure sensor monitors the internal pressure changes in real time, thereby accurately determining whether there is a leakage problem. The testing process is efficient and reliable, effectively improving the testing efficiency and accuracy.

[0042] In this embodiment, the pressure sensor can be directly installed inside the inflation component 201 (such as an inflation nozzle or inflation connector) or on its connecting pipe. During inflation, gas enters the speaker through the inflation component 201, and the pressure sensor monitors the pressure changes within the inflation pipe in real time. If there is a leak in the speaker, the internal pressure drop will immediately be fed back to the sensor, and the airtightness can be determined by the pressure decay rate.

[0043] The airtightness testing device for the audio equipment also includes a drive component 4, which is connected to the inflation component 201 and is used to drive the inflation component 201 to move in a set direction so as to achieve contact or separation with the part of the audio equipment being tested, thereby improving the automation level and ease of operation of the testing process.

[0044] Specifically, the drive assembly 4 includes a drive module 5 (such as a slide table) and a power source 6 (such as a cylinder). The drive module 5 is fixedly mounted on the worktable 1, and its output end is connected to the power source 6. The drive module 5 is used to move the power source 6 closer to or further away from the speaker under test. An inflation component 201 is installed at the output end of the power source 6, and the power source 6 is used to drive the inflation component 201 to contact or separate from the part of the speaker being tested. The drive module 5 moves the power source 6, and the power source 6 further drives the inflation component 201 to precisely fit or detach from the speaker's sealing opening, effectively improving detection efficiency and repeatability.

[0045] By setting up drive component 4, not only is manual intervention reduced and the operation difficulty lowered, but the stability and sealing reliability of the inflation process are also enhanced, making it suitable for rapid testing of various specifications of audio products.

[0046] Preferably, the positioning and clamping assembly 3 includes a motion source 301 (such as a slide table) and a mounting base 302 to achieve speaker positioning and improve loading / unloading efficiency and inspection continuity. In this embodiment, the mounting base 302 is mounted on the slider of the slide table, and the surface of the mounting base 302 is provided with a groove for fitting the speaker. The motion source 301 is disposed on the worktable 1. The mounting base 302 is used to support the speaker to be tested and is disposed at the output end of the motion source 301. The motion source 301 is used to drive the mounting base 302 to move along a set direction to achieve automatic loading or unloading of the speaker. In this embodiment, the positioning and clamping assembly 3 is provided in several sets, and multiple sets of positioning and clamping assemblies 3 constitute a multi-station inspection structure, which effectively improves equipment utilization and inspection cycle time, and is suitable for the high-efficiency airtightness inspection requirements in mass production.

[0047] The airtightness testing equipment for this audio equipment also includes a loading seat 7 and grippers 8 (such as cylinder grippers 8). The loading seat 7 is reciprocatingly mounted on the worktable 1 along the mounting base 302. In this embodiment, the loading seat 7 can be moved by a mounting slide. Both the loading seat 7 and the mounting base 302 are for supporting the audio equipment, and the number of loading seats 7 can be determined according to actual needs. The grippers 8 are mounted on the worktable 1 and reciprocate between the loading seat 7 and the mounting base 302 to grip or release the audio products. The grippers 8 can accurately complete the gripping and releasing actions, which is suitable for continuous multi-station operation, reduces manual intervention, and improves the stability and rhythm of the overall testing process. By setting up the reciprocating loading seat 7 and grippers 8 to work together, the automatic flow of audio products between loading, positioning, and testing is realized, effectively improving the automation level and testing efficiency of the equipment.

[0048] The airtightness testing equipment for this audio system also includes a labeling component 9, which is installed on the workbench 1. The labeling component 9 allows for automatic labeling of the product after the airtightness test is completed, improving the automation level of the equipment and the completeness of the testing process.

[0049] Specifically, the labeling assembly 9 includes a label reel 901, a power source 902, and a labeling head 903. Both the label reel 901 and the power source 902 are mounted on the worktable 1. The labeling head 903 is mounted on the output end of the power source 902. The power source 902 drives the labeling head 903 to peel the label from the label reel 901 and attach it to a designated position on the speaker surface. The entire process is automated, effectively reducing manual intervention and significantly improving the efficiency of automatic labeling.

[0050] Furthermore, the power source 902 includes an X-axis motion component 921 (such as a slide) and a Y-axis motion component 922 (such as a cylinder). The X-axis motion component 921 is mounted on the worktable 1. The Y-axis motion component 922 is mounted on the output end of the X-axis motion component 921. The labeling head 903 is mounted on the output end of the Y-axis motion component 922. The X-axis motion component 921 drives the Y-axis motion component 922 to move along the X-axis direction, and the Y-axis motion component 922 drives the labeling head 903 to move back and forth between the label reel 901 and the speaker. By setting the X-axis and Y-axis linked motion components to drive the labeling head 903, precise positioning and flexible movement of the labeling action are achieved, ensuring that the label is accurately attached to the designated position of the speaker.

[0051] The airtightness testing equipment for this speaker also includes a robotic arm 10, which is mounted on the worktable 1. The robotic arm 10 is used to pick up the speaker after testing and remove it from the positioning and clamping assembly 3 to complete the unloading. By setting up the robotic arm 10 to realize the automatic unloading operation of the speaker, the automation level of the equipment and the production cycle are improved, manual intervention is reduced, and the continuity of the testing process and the efficiency of operation are effectively improved.

[0052] The air tightness testing equipment for the audio equipment also includes a protective cover 11, which covers the workbench 1 and the air tightness testing component 2 and the positioning clamping component 3 on it. The protective cover 11 is used to isolate the testing area from the external environment, prevent operators from accidentally touching moving parts, and reduce the influence of external factors on the air tightness testing results.

[0053] The process for detecting airtightness in this invention is as follows:

[0054] The speaker to be tested is placed on the loading seat 7. The gripper 8 (such as a cylinder gripper 8) clamps the speaker and moves it to the mounting seat 302 of the positioning and clamping assembly 3. The groove on the surface of the mounting seat 302 is adapted to the shape of the speaker. The motion source 301 (such as a slide table) drives the mounting seat 302 to move in a set direction, so that the speaker is accurately positioned at the drive assembly 4 for testing. The drive assembly 4 is activated, and the drive module 5 (such as a slide table) drives the energy source 6 (such as a cylinder) to approach the speaker. The energy source 6 further drives the inflation component 201 (such as an inflation nozzle) to make tight contact with the part of the speaker to be tested (such as a sealing port). The inflation component 201 fills the speaker with a certain amount of gas (such as compressed air). The pressure sensor monitors the internal pressure changes in real time: if the pressure is maintained stably within the set threshold, the speaker is judged to be airtight; if the pressure drops rapidly, it is judged that there is a leak. The test results are recorded by the control system.

[0055] After the inspection is completed, the drive assembly 4 detaches the inflation component 201 from the speaker. If the inspection is qualified, the power source 902 (X-axis slide and Y-axis cylinder linkage) of the labeling assembly 9 drives the labeling head 903 to peel the qualified label from the label reel 901 and accurately attach it to the designated position on the speaker; if it is unqualified, an unqualified label is attached or the labeling is skipped. Finally, the robot arm 10 picks up the speaker from the positioning and clamping assembly 3, completes the unloading, and enters the subsequent process or sorting area.

[0056] This process, through the collaborative operation of multiple components, achieves fully automated operation from positioning, inflation, testing, labeling to unloading, effectively improving the efficiency, accuracy and safety of sound airtightness testing, and meeting the high-efficiency testing needs of mass production.

[0057] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
