Description

Technical Field

[0001] This invention belongs to the field of audio testing technology, and particularly relates to testing equipment and mobile phone production lines. Background Technology

[0002] With the rapid development of mobile communication technology, mobile phones have become indispensable devices in people's daily lives. Their audio performance, including the sound quality, volume, and noise reduction effect of the earpiece, speaker, and microphone, is a key indicator directly affecting user experience. Therefore, during the manufacturing process of mobile phones, rigorous and efficient testing of their audio components is essential to ensure that every product meets design standards. Mobile phone audio performance testing must be conducted in a highly soundproof, enclosed environment to prevent external noise from interfering with the accuracy of the test results.

[0003] Existing mobile phone audio testing equipment typically includes a test chamber with an opening for loading the phone, along with an automatic loading mechanism and a door panel mechanism for closing the opening. However, the spatial layout of this type of equipment has inherent flaws. Because the loading mechanism and the door panel mechanism are closely related in spatial position, interference often occurs during equipment operation. After loading is completed, parts of the loading mechanism may obstruct the normal movement trajectory of the door panel, preventing it from closing completely or leaving gaps after closure. This sealing problem caused by mechanical interference disrupts the acoustic environment required for testing, allowing external environmental noise to enter the test chamber and thus affecting the accuracy and reliability of the test results. Summary of the Invention

[0004] The purpose of this application is to provide a testing device and a mobile phone production line, aiming to solve the problem of how to improve the accuracy of testing.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: In a first aspect, a testing device is provided, comprising a testing mechanism, a sealing mechanism, and a feeding mechanism for conveying materials. The testing mechanism includes a housing rotatably arranged around a preset axis and having a soundproof cavity, and a testing component disposed within the soundproof cavity. The housing has a first opening communicating with the soundproof cavity. The sealing mechanism and the feeding mechanism are arranged circumferentially around the housing. The sealing mechanism includes a door panel slidably arranged in a first direction and a driving member for driving the door panel. The housing has a first position state and a second position state. When the housing is in the first position state, the first opening is connected to the feeding mechanism, and the feeding mechanism conveys the material through the first opening into the soundproof cavity. When the housing is in the second position state, the first opening corresponds to the door panel, the driving member drives the door panel to move toward the first opening and close the first opening, and the testing component detects the material.

[0006] In some embodiments, the testing equipment further includes a drive mechanism, the housing is connected to the output end of the drive mechanism, and the drive mechanism is used to drive the housing to rotate so that the first opening corresponds to the feeding mechanism or the door panel.

[0007] In some embodiments, the testing equipment further includes a feeding mechanism spaced apart from the housing. The feeding mechanism and the feeding mechanism are respectively located on opposite sides of the housing along a second direction, which is angled to the first direction. The housing has a second opening communicating with the sound insulation cavity. When the housing is in the first position, the first opening and the second opening are respectively connected to the feeding mechanism and the feeding mechanism. The feeding mechanism is used to feed the material after the test is completed.

[0008] In some embodiments, two closure mechanisms are arranged at intervals, and the two closure mechanisms are respectively located on opposite sides of the box body along the first direction; when the box body is in the second position state, the two door panels correspond to the first opening and the second opening respectively, and the two door panels are used to close the first opening and the second opening respectively.

[0009] In some embodiments, the testing mechanism further includes a receiving structure disposed within the soundproof cavity and used to carry the material. The testing component is adjacent to the receiving structure. When the housing is in the first position state, the two ends of the receiving structure are respectively connected to the feeding mechanism and the unloading mechanism. The receiving structure is used to receive the material at the feeding mechanism and to transport the tested material to the unloading mechanism.

[0010] In some embodiments, the receiving structure includes a first seat and a second seat spaced apart from the first seat. The first seat and the second seat are respectively connected to a first conveyor line and a second conveyor line. The first conveyor line and the second conveyor line are used to convey the material. The first conveyor line and the second conveyor line respectively support the opposite ends of the material. The second seat is slidably disposed relative to the first seat to adjust the distance between the first conveyor line and the second conveyor line.

[0011] In some embodiments, both the first direction and the second direction intersect the preset axis.

[0012] In some embodiments, the housing is a cylindrical structure, and the central axis of the housing is configured as the preset axis.

[0013] In some embodiments, the testing assembly includes a plurality of testing elements, each of which is used to test different parameters of the material; the testing mechanism further includes a clamping structure disposed within the sound insulation cavity, wherein a plurality of clamping structures are arranged at intervals and each clamping structure corresponds one-to-one with each of the testing elements; the clamping structure includes a linear adjustment assembly and a rotating member rotatably connected to the linear adjustment assembly, the testing element is connected to the rotating member, the linear adjustment assembly is used to drive the rotating member to move in a straight line to adjust the position of the testing element, and the rotating member is used to adjust the orientation of the testing element relative to the material.

[0014] Secondly, a mobile phone production line is provided, including the aforementioned testing equipment. The testing equipment provided in this application allows the housing to rotate around a preset axis, enabling it to switch between a first position and a second position. First, the housing rotates to the first position, where the first opening aligns with the feeding mechanism. The feeding mechanism then transfers materials into the soundproof cavity through the first opening, completing the feeding process. Next, the housing rotates to the second position, where the first opening aligns with the door panel. Since both the first opening and the door panel are offset from the feeding mechanism, the driving component can drive the door panel towards and close the first opening without obstruction. This avoids interference from the feeding mechanism on the door panel's sliding path, ensuring the first opening is closed. This provides a reliable soundproof environment for material testing and improves testing accuracy. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0022] Please see Figures 1 to 6 This application provides a testing device, including a testing mechanism 10, a sealing mechanism 20, and a feeding mechanism 30 for conveying materials 200. The testing mechanism 10 includes a housing 11 rotatably arranged around a preset axis a and having a sound insulation cavity 113, and a testing component 12 disposed within the sound insulation cavity 113. The housing 11 has a first opening 111 communicating with the sound insulation cavity 113. The sealing mechanism 20 and the feeding mechanism 30 are arranged circumferentially around the housing 11. The sealing mechanism 20 includes a door panel 21 slidably arranged along a first direction b. The housing 11 has a first position state and a second position state. When the housing 11 is in the first position state, the first opening 111 is connected to the feeding mechanism 30, and the feeding mechanism 30 conveys the material 200 through the first opening 111 into the sound insulation cavity 113. When the housing 11 is in the second position state, the first opening 111 corresponds to the door panel 21, and the driving component 22 drives the door panel 21 to move toward the first opening 111 and close the first opening 111. The testing component 12 detects the material 200.

[0023] It should be noted that, in this embodiment, the material 200 is a mobile phone, and the testing organization 10 tests the mobile phone. Specifically, the testing organization 10 can perform audio tests on the mobile phone. Understandably, the mobile phone under test has a speaker and a microphone inside, and the testing component 12 in this embodiment can test the speaker and microphone inside the mobile phone. Of course, in other possible embodiments, the material 200 can also be other terminal devices. This application does not limit the specific type of material 200, thus enabling the housing 11 to rotate normally.

[0024] In this embodiment, the preset axis a extends vertically, while the first direction b extends horizontally, meaning the preset axis a and the first direction b are perpendicular to each other. Optionally, the first opening 111 can be located on the side wall of the housing 11. When the preset axis a of the housing 11 rotates, the first opening 111 has different orientations, allowing it to correspond to either the door panel 21 or the feeding mechanism 30. Understandably, when the feeding mechanism 30 feeds the material 200 into the soundproof cavity 113, the feeding mechanism 30 will not interfere with the rotation of the housing 11.

[0025] The testing equipment provided in this application allows the housing 11 to rotate around a preset axis a, enabling it to switch between a first position and a second position. The housing 11 first rotates to the first position, where the first opening 111 aligns with the feeding mechanism 30. The feeding mechanism 30 then transfers the material 200 into the soundproof cavity 113 through the first opening 111, completing the feeding process. Next, the housing 11 rotates to the second position, where the first opening 111 aligns with the door panel 21. Since both the first opening 111 and the door panel 21 are offset from the feeding mechanism 30, the driving component 22 can drive the door panel 21 towards and close the first opening 111 without obstruction. This avoids interference from the feeding mechanism 30 on the sliding path of the door panel 21, ensuring the first opening 111 is closed. This provides a reliable soundproof environment for testing the material 200 and improves the accuracy of the test.

[0026] In this embodiment, when the housing 11 switches from the first position state to the second position state, the housing 11 rotates by a preset angle, which ranges from 30° to 45°. Understandably, the preset angle cannot be too large, as this would increase the time required for the housing 11 to switch between the first and second position states, thereby reducing production efficiency; nor can the preset angle be too small, as this would prevent the first opening 111 and the door panel 21 from being completely misaligned with the feeding mechanism 30.

[0027] Understandably, such as Figure 1 and Figure 4As shown, this application also includes an electrical control box 60. The feeding mechanism 30, the testing mechanism 10, and the closing mechanism 20 are all connected to the electrical control box 60 in communication. The electrical control box 60 can control the feeding mechanism 30, the testing mechanism 10, and the closing mechanism 20 to automatically cooperate and operate, thereby reducing the impact of human factors and improving production efficiency.

[0028] In some embodiments, such as Figure 4 As shown, the testing equipment also includes a drive mechanism 50. The housing 11 is connected to the output end of the drive mechanism 50. The drive mechanism 50 is used to drive the housing 11 to rotate so that the first opening 111 corresponds to the feeding mechanism 30 or the door panel 21. By setting the drive mechanism 50, the drive mechanism 50 provides power for the rotational movement of the housing 11, which allows the first opening 111 of the housing 11 to switch precisely and quickly between a first position state and a second position state, thereby further improving testing efficiency. Moreover, the drive mechanism 50 uses the rotation of the housing 11 to switch work positions, rather than using multiple linear motion modules, making the overall structure of the equipment more compact. Optionally, the drive mechanism 50 is a motor. The motor can receive control signals, drive the housing 11 to rotate around a preset axis a by a specific angle, and enable it to stop accurately and remain stable in the first position state and the second position state.

[0029] Optionally, the housing 11 is located above the electrical control box 60, and the electrical control box 60 supports the housing 11. The electrical control box 60 has a cavity 61, which forms an opening towards the housing 11. The drive mechanism 50 is located inside the cavity 61, thereby making full use of the space and making the overall structure of the testing equipment more compact.

[0030] In some embodiments, such as Figure 2 and Figure 4 As shown, the testing equipment also includes a feeding mechanism 40 spaced apart from the housing 11. The feeding mechanism 30 and the feeding mechanism 40 are respectively located on opposite sides of the housing 11 along the second direction c, which is angled to the first direction b. The housing 11 has a second opening 112 communicating with the sound insulation cavity 113. When the housing 11 is in the first position, the first opening 111 and the second opening 112 are respectively connected to the feeding mechanism 30 and the feeding mechanism 40. The feeding mechanism 40 is used to feed the tested material 200. Optionally, the feeding mechanism 30 and the feeding mechanism 40 are belt conveyors.

[0031] Understandably, by setting the feeding mechanism 30 and the unloading mechanism 40 opposite each other on both sides of the housing 11 along the second direction c, and correspondingly setting the first opening 111 and the second opening 112, when the housing 11 is in the first position, the material to be tested 200 enters the housing 11 from the feeding mechanism 30 on one side, and the material 200 that has been tested in the housing 11 can be taken out by the unloading mechanism 40 on the other side. This eliminates the time waiting and action redundancy caused by the material 200 still having to return along the original path after testing in traditional equipment, thereby greatly improving production efficiency.

[0032] In addition, by setting a first opening 111 and a second opening 112 arranged at intervals along the second direction c, and the line connecting the first opening 111 and the second opening 112 is a straight line, the material 200 flows in a single and orderly direction, which facilitates the straight-line docking and integration of the entire testing equipment with the automated equipment at the front and rear workstations, and simplifies the layout planning of the entire production line.

[0033] In some embodiments, such as Figure 3 and Figure 4 As shown, two closing mechanisms 20 are arranged at intervals, respectively located on opposite sides of the housing 11 along the first direction b. When the housing 11 is in the second position, the two door panels 21 correspond to the first opening 111 and the second opening 112, respectively, and are used to close the first opening 111 and the second opening 112. When the housing 11 rotates to the second position, the two door panels 21 can move simultaneously to close the first opening 111 and the second opening 112, thereby ensuring that the housing 11 is in a completely closed state and further improving the accuracy of the test. Understandably, after the test is completed, the driving component 22 drives the door panel 21 to move away from the first opening 111 or the second opening 112, thereby separating the door panel 21 from the first opening 111 or the second opening 112, thus not hindering the housing 11 from rotating back to the first position.

[0034] Optional, such as Figure 5 As shown, the closing mechanism 20 also includes a base 23 for mounting the drive unit 22 and a connecting frame slidably connected to the base 23 along the first direction b. The connecting frame includes a connecting plate 241 and two side plates 242 connected to both sides of the connecting plate 241. The connecting plate 241 is connected between the output end of the drive unit 22 and the door panel 21. The side plates 242 extend away from the door panel 21. Two mounting plates 25 are respectively connected to the opposite sides of the base 23. The mounting plates 25 are connected to sliders 26. The side plates 242 are connected to slide rails 27 extending along the first direction b. The two slide rails 27 are slidably connected to the two sliders 26 respectively, thereby guiding the sliding of the connecting frame and the door panel 21, ensuring the straightness of the door panel 21 movement, and ensuring that the door panel 21 can close the first opening 111 or the second opening 112.

[0035] In some embodiments, such as Figure 4 As shown, the testing mechanism 10 also includes a receiving structure 13 disposed in the sound insulation cavity 113 and used to carry the material 200. The testing component 12 is adjacent to the receiving structure 13. When the box 11 is in the first position, the two ends of the receiving structure 13 are respectively connected to the feeding mechanism 30 and the unloading mechanism 40. The receiving structure 13 is used to receive the material 200 at the feeding mechanism 30 and to transport the tested material 200 to the unloading mechanism 40.

[0036] In actual operation, the feeding mechanism 30 transfers the material 200 through the first opening 111 to the receiving structure 13. Then, the housing 11 rotates to the second position and closes. After the material 200 is tested, the housing 11 rotates back to the first position, and the unloading mechanism 40 removes the tested material 200 from the receiving structure 13. This ensures that the entire material transfer process takes place inside the housing 11. After the material 200 is transferred, the housing 11 can immediately leave with the material 200, making the entire loading / unloading and testing process faster and more precise, thereby further reducing production cycle time and improving overall efficiency. Furthermore, by setting up the receiving structure 13, the material 200 can be stably supported on it, effectively avoiding interference from minor vibrations that may be caused by the rotation of the housing 11 or the opening and closing of the door 21 on the precision audio testing.

[0037] Understandably, the housing 11 is provided with a first opening 111 and a second opening 112, that is, the test device in this application embodiment is a through-type test device. In the prior art, if the testing equipment is set to a through-type structure, the door panel 21 is slidably disposed on the housing 11 so that the first opening 111 can be closed or opened. In order to reserve opening and closing space for the door panel 21, the feeding mechanism 30 is set with a large distance between the feeding mechanism 30 and the housing 11, which results in a larger gap between the feeding mechanism 30 and the receiving structure 13. Therefore, if the material 200 is a mobile phone, the small size of the mobile phone will prevent it from being transported between the feeding mechanism 30 and the receiving structure 13, and it will fall through the gap between the feeding mechanism 30 and the receiving structure 13. However, the housing 11 of this application can be rotated to the second position to be closed. Therefore, the feeding mechanism 30 does not need to reserve opening and closing space for the door panel 21, so that the feeding mechanism 30 can be close to the housing 11, thereby reducing the gap between the feeding mechanism 30 and the receiving structure 13. Therefore, the safety of the material 200 being transported between the feeding mechanism 30 and the receiving structure 13 can be increased.

[0038] In some embodiments, such as Figure 6As shown, the receiving structure 13 includes a first base 131 and a second base 132 spaced apart from the first base 131. The first base 131 and the second base 132 are respectively connected to a first conveyor line 133 and a second conveyor line 134. The first conveyor line 133 and the second conveyor line 134 are used to convey material 200. The first conveyor line 133 and the second conveyor line 134 respectively support the opposite ends of the material 200. The second base 132 is slidably disposed relative to the first base 131 to adjust the spacing between the first conveyor line 133 and the second conveyor line 134. Optionally, the first conveyor line 133 and the second conveyor line 134 are parallel to each other. When the box 11 is in the first position, the first conveyor line 133 and the second conveyor line 134 receive the material 200 from the feeding mechanism 30 and can convey the material 200 forward until the material 200 is conveyed to the test position and stops. When the test is completed and the box 11 rotates back to the first position, the first conveyor line 133 and the second conveyor line 134 can continue to convey the material 200 forward, so that the material 200 can be conveyed to the unloading mechanism 40 to complete the unloading.

[0039] In this embodiment, by sliding the second seat 132 relative to the first seat 131, the distance between the first conveyor line 133 and the second conveyor line 134 can be adjusted, thereby adapting to materials 200 of different widths and sizes. This greatly expands the application range of the equipment, eliminating the need to prepare multiple sets of receiving structures 13 to adapt to different materials 200, thus significantly saving equipment modification costs caused by product switching. Furthermore, the first conveyor line 133 and the second conveyor line 134 jointly support the material 200. Compared to single-point or central support, end-support avoids the possibility of bending or vibration of the long strip material 200 due to its own weight or conveying vibration, providing a stable physical basis for audio testing. Optionally, the receiving structure 13 also includes a base plate 136 and a guide rail 135 disposed on the top surface of the base plate 136. The first seat 131 is connected to the top surface of the base plate 136, and the second seat 132 is slidably connected to the guide rail 135, thereby realizing the sliding of the second seat 132 relative to the first seat 131.

[0040] Optionally, the first conveyor line 133 and the second conveyor line 134 are belt conveyors. Belt conveyors rely on continuous friction drive, and their transmission characteristics are smooth and gentle. When starting and stopping, they can effectively avoid impacting the material 200 or causing it to slip, ensuring the stability of the material 200 when entering and leaving the test position. This ensures the consistency of the relative position between the material 200 and the test component 12 during each test. Compared with chain, gear, or roller conveyors, belt conveyors generate less noise during operation, which is conducive to achieving smooth and low-noise transmission. In addition, belt materials are usually softer and more elastic than metal or hard plastic. The belt directly contacts and supports the two sides of the mobile phone, which can greatly avoid scratching or abrading the mobile phone's casing, frame, or screen during the conveying process, effectively protecting the appearance quality of the mobile phone.

[0041] In some embodiments, both the first direction b and the second direction c intersect with the preset axis a, that is, the line connecting the two closed mechanisms 20 and the line connecting the loading mechanism 30 and the unloading mechanism 40 intersects with the preset axis a. The two closed mechanisms 20 are symmetrically arranged about the preset axis a, and the loading mechanism 30 and the unloading mechanism 40 are also symmetrically arranged about the preset axis a. The symmetrical layout improves the symmetry and repeatability of the loading and unloading actions and the closing action of the door panel 21, simplifies the writing of motion control programs, and only one set of logic for one workstation is needed, which can be copied to another workstation by rotating 180°, reducing the complexity of debugging and maintenance. At the same time, the symmetrical layout also improves the aesthetics of the spatial layout.

[0042] In some embodiments, the enclosure 11 has a cylindrical structure, and the central axis of the enclosure 11 is configured as a preset axis a. By setting the enclosure 11 to a cylindrical structure, the sound insulation cavity 113 inside the enclosure 11 is also a cylindrical structure. Unlike the square enclosure 11 which has sharp corners, the cylindrical cavity has no sharp angles, which can effectively reduce the distortion of sound waves, the formation of standing waves, and unnecessary reflections, making the sound field distribution inside the sound insulation cavity 113 more uniform and stable, and greatly improving the accuracy of the test data.

[0043] In addition, the cylindrical box 11 and its rotational movement are naturally adapted to the central radial layout with the preset axis a as the core. The feeding mechanism 30, the unloading mechanism 40 and the two closing mechanisms 20 can be compactly arranged around the box 11 along the circumferential tangent direction. This layout eliminates the "dead corner" space that is difficult to utilize in traditional straight or right-angle layouts, so that the utilization rate of the testing equipment in three-dimensional space is maximized. The overall structure is very compact and regular, which greatly saves the floor space of the testing equipment.

[0044] In some embodiments, such as Figure 6As shown, the test assembly 12 includes multiple test elements 121, each of which is used to test different parameters of the material 200; the test mechanism 10 also includes a clamping structure 14 disposed in the sound insulation cavity 113, multiple clamping structures 14 are arranged at intervals and each clamping structure 14 corresponds to each test element 121; the clamping structure 14 includes a linear adjustment assembly and a rotating member 142 rotatably connected to the linear adjustment assembly, the test element 121 is connected to the rotating member 142, the linear adjustment assembly is used to drive the rotating member 142 to move in a straight line to adjust the position of the test element 121, and the rotating member 142 is used to adjust the orientation of the test element 121 relative to the material 200.

[0045] Understandably, by adjusting the linear movement of the test element 121, the distance between the test element 121 and the part of the mobile phone to be tested can be precisely controlled, thereby meeting the requirements of different test standards and ensuring the repeatability of test results. By rotating the test element 121, the orientation and angle of the test element 121 can be precisely changed, ensuring that the sound wave energy is transmitted along the optimal path, avoiding acoustic attenuation and signal distortion caused by angular deviation, thereby acquiring the most realistic and accurate audio signal and further improving the accuracy of the test.

[0046] Specifically, when the material 200 is a mobile phone, the multiple test components 12 include a test microphone and an artificial mouth. The test microphone is located near the speaker inside the mobile phone. The speaker inside the mobile phone plays audio signals from inside the mobile phone, and the test microphone can receive the sound emitted by the mobile phone speaker and test it, thereby detecting the performance of the mobile phone speaker. The artificial mouth can simulate the characteristics of human mouth speech and play test audio signals to the microphone of the mobile phone under test, thereby detecting the microphone of the mobile phone under test. Thus, the test component 12 of this application embodiment can simultaneously complete the performance acquisition and analysis of the mobile phone microphone and mobile phone speaker in one test process. It can simultaneously or sequentially perform comprehensive automated testing of the audio performance of multiple parts of the mobile phone in one closed test cycle, which greatly shortens the test time, reduces the number of equipment clamping, test process initiation and repetitive operations, and significantly reduces time and labor costs.

[0047] Optionally, the linear adjustment assembly includes a horizontally extending crossbar 1411, a connecting block 1412 slidably connected to the crossbar 1411, and a vertical bar 1413 connected to the connecting block 1412 and extending vertically. A rotating member 142 is rotatably connected to the bottom end of the vertical bar 1413 and clamps the test element 121, thereby driving the test element 121 to rotate. Furthermore, the crossbar 1411 and the connecting block 1412 are provided with scales, facilitating adjustment according to the scales and improving the consistency and accuracy of the adjustment.

[0048] The present invention also proposes a mobile phone production line, which includes testing equipment. The specific structure of the testing equipment is as described in the above embodiments. Since the mobile phone production line adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0049] In summary, the testing equipment provided in this application allows the housing 11 to rotate around a preset axis a, enabling it to switch between a first position and a second position. The housing 11 first rotates to the first position, where the first opening 111 aligns with the feeding mechanism 30. The feeding mechanism 30 then conveys the material 200 into the soundproof cavity 113 through the first opening 111, completing the feeding process. Next, the housing 11 rotates to the second position, where the first opening 111 aligns with the door panel 21. Since both the first opening 111 and the door panel 21 are offset from the feeding mechanism 30, the driving component 22 can drive the door panel 21 towards and close the first opening 111 without obstruction. This avoids interference from the feeding mechanism 30 on the sliding path of the door panel 21, ensuring the first opening 111 is closed. This provides a reliable soundproof environment for testing the material 200 and improves the accuracy of the test.

[0050] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
