Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of audio testing, and particularly relates to a test device and a mobile phone production line. BACKGROUND

[0002] With the rapid development of mobile communication technology, mobile phones have become an indispensable device in people's daily life. The audio performance, including the sound quality, volume and noise reduction effect of the earpiece, loudspeaker and microphone, is a key indicator that directly affects the user experience. Therefore, during the production and manufacturing process of mobile phones, the audio components must be strictly and efficiently tested to ensure that each product meets the design standards. Mobile phone audio performance testing needs to be carried out in a highly soundproof and sealed environment to prevent external noise from interfering with the accuracy of the test results.

[0003] The existing mobile phone audio test device usually includes a test box body, which is provided with an opening for loading mobile phones, and is matched with an automatic loading mechanism and a door plate mechanism for closing the opening. However, the spatial layout of such devices has inherent defects. Since the loading mechanism and the door plate mechanism are closely related in spatial position, it often causes motion interference during the operation of the device. After loading, part of the structure of the loading mechanism may hinder the normal movement trajectory of the door plate, so that the door plate cannot be completely closed, or there is still a gap after being closed. The problem of poor sealing caused by mechanical interference will destroy the acoustic environment required for testing, causing external environmental noise to invade the test cavity, and thus affecting the accuracy and reliability of the test results.

[0030] Please refer to Figures 1 to 6The embodiment of the present application provides a test device, which comprises a test mechanism 10, a sealing mechanism 20 and a feeding mechanism 30 for feeding materials 200, the test mechanism 10 comprises a box 11 rotatably arranged around a preset axis a and provided with a soundproof cavity 113 and a test assembly 12 arranged in the soundproof cavity 113, the box 11 is provided with a first opening 111 in communication with the soundproof cavity 113; the sealing mechanism 20 and the feeding mechanism 30 are arranged along the circumference of the box 11, the sealing mechanism 20 comprises a door plate 21 slidably arranged along a first direction b and a driving member 22 for driving the door plate 21; the box 11 has a first position state and a second position state, when the box 11 is in the first position state, the first opening 111 is in butt joint with the feeding mechanism 30, and the feeding mechanism 30 conveys the materials 200 into the soundproof cavity 113 through the first opening 111; when the box 11 is in the second position state, the first opening 111 corresponds to the door plate 21, the driving member 22 drives the door plate 21 to move towards the first opening 111 and seals the first opening 111, and the test assembly 12 detects the materials 200.

[0031] It should be noted that the materials 200 are mobile phones in the embodiment of the present application, the test mechanism 10 tests the mobile phones, specifically, the test mechanism 10 can perform audio test on the mobile phones. It can be understood that the mobile phones to be tested are internally provided with loudspeakers and microphones, and the test assembly 12 in the embodiment of the present application can test the loudspeakers and microphones in the mobile phones. Of course, in other possible embodiments, the materials 200 can also be other terminal devices, and the present application does not limit the specific types of the materials 200, so that the box 11 can rotate normally.

[0032] In the embodiment of the present application, the preset axis a extends along the vertical direction, and the first direction b extends along the horizontal direction, that is, the preset axis a and the first direction b are perpendicular to each other. Optionally, the first opening 111 can be arranged on the side wall of the box 11, when the box 11 rotates around the preset axis a, the first opening 111 has different orientations, so that the first opening 111 can correspond to the door plate 21 or the feeding mechanism 30 respectively. It can be understood that after the feeding mechanism 30 feeds the materials 200 into the soundproof cavity 113, the feeding mechanism 30 will not interfere with the rotation of the box 11.

[0033] The test equipment provided in the application can switch the box body 11 between the first position state and the second position state by rotating the box body 11 around the preset axis a. The box body 11 is first rotated to the first position state, at which time the first opening 111 is in butt joint with the feeding mechanism 30, and the feeding mechanism 30 transmits the material 200 into the soundproof cavity 113 through the first opening 111 to complete the feeding. Then, the box body 11 is rotated to the second position state, and the first opening 111 corresponds to the door plate 21. At this time, since the first opening 111 and the door plate 21 are staggered with the feeding mechanism 30, the driving part 22 can drive the door plate 21 to move towards the first opening 111 and close the first opening 111 without obstruction, avoiding the interference of the feeding mechanism 30 on the sliding path of the door plate 21, ensuring that the first opening 111 is closed, so as to build a reliable soundproof environment for the material 200 test and improve the accuracy of the test.

[0034] In the embodiment of the application, when the box body 11 is switched from the first position state to the second position state, the box body 11 is rotated by a preset angle, and the range of the preset angle is 30°-45°. Understandably, the preset angle cannot be too large, otherwise the time consumed for switching the box body 11 between the first position state and the second position state will be increased, thereby reducing the production efficiency. The preset angle also cannot be too small, otherwise it cannot be ensured that the first opening 111 and the door plate 21 can be completely staggered with the feeding mechanism 30.

[0035] Understandably, as shown in Figure 1 and Figure 4 , the application further includes an electric control box 60, and the feeding mechanism 30, the test mechanism 10, and the closing mechanism 20 are in communication connection with the electric control box 60. The electric control box 60 can control the feeding mechanism 30, the test mechanism 10, and the closing mechanism 20 to automatically cooperate and operate, thereby reducing the influence of human factors and improving the production efficiency.

[0036] In some embodiments, as shown in Figure 4 , the test equipment further includes a driving mechanism 50, and the box body 11 is connected with the output end of the driving mechanism 50. The driving mechanism 50 is used to drive the box body 11 to rotate, so that the first opening 111 corresponds to the feeding mechanism 30 or the door plate 21. By arranging the driving mechanism 50, the driving mechanism 50 provides power for the rotational movement of the box body 11, so that the first opening 111 of the box body 11 can be accurately and quickly switched between the first position state and the second position state, thereby further improving the test efficiency. Moreover, the driving mechanism 50 makes the box body 11 rotate to switch the station, instead of using multiple linear motion modules for driving, so that the overall structure of the equipment is more compact. Optionally, the driving mechanism 50 is a motor, which can receive a control signal, drive the box body 11 to rotate by a specific angle around the preset axis a, and accurately stop and keep stable in the first position state and the second position state.

[0037] Optionally, the box 11 is arranged above an electric control box 60, the electric control box 60 supports the box 11, the electric control box 60 is provided with a cavity 61, the cavity 61 is open to the box 11, and the driving mechanism 50 is arranged in the cavity 61, so that the space can be fully utilized, and the overall structure of the testing equipment is more compact.

[0038] In some embodiments, as shown in Figure 2 and Figure 4 , the testing equipment further comprises a discharging mechanism 40 arranged away from the box 11, the feeding mechanism 30 and the discharging mechanism 40 are arranged on opposite sides of the box 11 along a second direction c, the second direction c is arranged at an angle to the first direction b, the box 11 is provided with a second opening 112 communicating with the soundproof cavity 113, the first opening 111 and the second opening 112 are respectively connected to the feeding mechanism 30 and the discharging mechanism 40 when the box 11 is in the first position state, and the discharging mechanism 40 is used for discharging the tested material 200. Optionally, the feeding mechanism 30 and the discharging mechanism 40 are belt conveying lines.

[0039] It can be understood that by arranging the feeding mechanism 30 and the discharging mechanism 40 on opposite sides of the box 11 along the second direction c, and correspondingly arranging the first opening 111 and the second opening 112, when the box 11 is in the first position state, the material 200 to be tested enters the box 11 from the feeding mechanism 30 on one side, and the tested material 200 in the box 11 can be taken out by the discharging mechanism 40 on the other side, eliminating the time waiting and action redundancy caused by the tested material 200 returning to the original route in the traditional equipment, thereby greatly improving the production efficiency.

[0040] In addition, by arranging the first opening 111 and the second opening 112 spaced apart along the second direction c, the line between the first opening 111 and the second opening 112 is a straight line, so that the flow direction of the material 200 is single and orderly, facilitating the straight-line connection and integration of the entire testing equipment with the automatic equipment of the front and rear stations, and simplifying the layout planning of the entire production line.

[0041] In some embodiments, as shown in Figure 3 and Figure 4As shown, the closing mechanism 20 is arranged in pairs, and two closing mechanisms 20 are arranged on opposite sides of the box body 11 along the first direction b; when the box body 11 is in the second position state, the two door plates 21 correspond to the first opening 111 and the second opening 112 respectively, and the two door plates 21 are used to close the first opening 111 and the second opening 112 respectively. When the box body 11 rotates to the second position state, the two door plates 21 can act simultaneously to close the first opening 111 and the second opening 112 respectively, so as to ensure that the box body 11 is in a completely closed state, further improving the accuracy of the test. It can be understood that when the test is completed, the driving member 22 drives the door plate 21 to move away from the first opening 111 or the second opening 112, so that the door plate 21 is separated from the first opening 111 or the second opening 112, so as not to hinder the rotation of the box body 11 back to the first position state.

[0042] Optionally, as shown in Figure 5 The closing mechanism 20 further comprises a base 23 for mounting the driving member 22 and a connecting frame slidingly connected to the base 23 along the first direction b, the connecting frame comprising a connecting plate 241 and two side plates 242 connected to the two sides of the connecting plate 241, the connecting plate 241 being connected between the output end of the driving member 22 and the door plate 21, and the side plates 242 extending away from the door plate 21, the opposite sides of the base 23 being respectively connected to two mounting plates 25, the mounting plates 25 being connected to sliding blocks 26, and the side plates 242 being connected to sliding rails 27 extending along the first direction b, the two sliding rails 27 being respectively slidingly connected to the two sliding blocks 26, so as to guide the sliding of the connecting frame and the door plate 21, ensure the straightness of the movement of the door plate 21, and ensure that the door plate 21 can close the first opening 111 or the second opening 112.

[0043] In some embodiments, as shown in Figure 4 The test mechanism 10 further comprises a material receiving structure 13 arranged in the soundproof cavity 113 and used for carrying the material 200, and the test assembly 12 is adjacent to the material receiving structure 13; when the box body 11 is in the first position state, the two ends of the material receiving structure 13 are respectively connected to the feeding mechanism 30 and the discharging mechanism 40, the material receiving structure 13 is used for receiving the material 200 at the feeding mechanism 30 and for conveying the material 200 after the test to the discharging mechanism 40.

[0044] In actual work process, the feeding mechanism 30 delivers the material 200 to the receiving structure 13 through the first opening 111, then the box 11 rotates to the second position state and is closed, after the material 200 is tested, the box 11 rotates back to the first position state, and the discharging mechanism 40 takes away the tested material 200 from the receiving structure 13, which makes the handover process of the material 200 in the box 11, and the box 11 can leave with the material 200 after the handover of the material 200 is completed, so that the whole feeding and discharging process and the testing process are faster and more accurate, thereby further compressing the production rhythm and improving the overall efficiency. In addition, by setting the receiving structure 13, the material 200 can be stably carried on the receiving structure 13, effectively avoiding the interference of the slight vibration caused by the rotation of the box 11 or the opening and closing action of the door plate 21 on the precise audio test.

[0045] It can be understood that the box 11 is provided with the first opening 111 and the second opening 112, that is, the testing device of the embodiment of the application is a middle-through type testing device. In the prior art, if the testing device is set as a middle-through type structure, the door plate 21 is slidingly arranged on the box 11 so as to close or open the first opening 111, and the spacing between the feeding mechanism 30 and the box 11 is set to be large in order to reserve space for the opening and closing of the door plate 21, which results in that the spacing between the feeding mechanism 30 and the receiving structure 13 is large, so if the material 200 is a mobile phone, the size of the mobile phone is small, which results in that the mobile phone cannot be transported between the feeding mechanism 30 and the receiving structure 13, and will fall from the gap between the feeding mechanism 30 and the receiving structure 13, and the box 11 of the application can rotate to the second position state to be closed, so the feeding mechanism 30 does not need to reserve space for the opening and closing of the door plate 21, so that the feeding mechanism 30 can be close to the box 11, thereby reducing the spacing between the feeding mechanism 30 and the receiving structure 13, so as to increase the safety of the transportation of the material 200 between the feeding mechanism 30 and the receiving structure 13.

[0046] In some embodiments, as Figure 6As shown, the material receiving structure 13 comprises a first seat body 131 and a second seat body 132 arranged in a spaced manner with the first seat body 131, the first seat body 131 and the second seat body 132 are respectively connected with a first conveying line 133 and a second conveying line 134, the first conveying line 133 and the second conveying line 134 are used for conveying the material 200, the first conveying line 133 and the second conveying line 134 respectively support opposite ends of the material 200, and the second seat body 132 is arranged in a sliding manner relative to the first seat body 131 to adjust the spacing between the first conveying line 133 and the second conveying line 134. Optionally, the first conveying line 133 and the second conveying line 134 are parallel to each other, when the box body 11 is in the first position state, the first conveying line 133 and the second conveying 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 stopped; and when the test is completed and the box body 11 is rotated to the first position state again, the first conveying line 133 and the second conveying line 134 can continue to convey the material 200 forward, so that the material 200 can be conveyed to the discharging mechanism 40 to complete the discharging.

[0047] In the embodiment of the present application, by sliding the second seat body 132 relative to the first seat body 131, the spacing between the first conveying line 133 and the second conveying line 134 is adjusted, so that the material 200 of different widths and sizes can be adapted, greatly expanding the application range of the equipment, without preparing multiple sets of material receiving structures 13 to adapt to different materials 200, thereby significantly saving the equipment modification cost caused by product switching. Moreover, the first conveying line 133 and the second conveying line 134 jointly support the material 200, compared with single-point or middle support, two-end support avoids the possibility of bending or trembling of the long-strip-shaped material 200 due to its own weight or conveying vibration, providing a stable physical basis for audio testing. Optionally, the material receiving structure 13 further comprises a bottom plate 136 and a guide rail 135 arranged on the top surface of the bottom plate 136, the first seat body 131 is connected to the top surface of the bottom plate 136, and the second seat body 132 is slidingly connected to the guide rail 135, so as to realize the sliding of the second seat body 132 relative to the first seat body 131.

[0048] Optionally, the first conveying line 133 and the second conveying line 134 are belt conveying lines, which rely on continuous friction drive, have smooth and soft transmission characteristics, and can effectively avoid impact on the material 200 or cause the material 200 to slide when starting and stopping, thereby ensuring that the material 200 is stable when entering and leaving the test position, ensuring the consistency of the relative position between the material 200 and the test assembly 12 each time the test is performed, and the belt conveying line produces lower noise during operation than a chain, gear, or roller line, which is conducive to achieving smooth and low-noise transmission. In addition, the belt material is generally softer and more elastic than metal or hard plastic, and the two sides of the mobile phone are directly contacted and supported by the belt, which can greatly avoid scratching or wearing the shell, middle frame, or screen of the mobile phone during the conveying process, effectively protecting the appearance quality of the mobile phone.

[0049] In some embodiments, the first direction b and the second direction c both intersect the preset axis a, that is, the connecting line of the two closing mechanisms 20 and the connecting line of the feeding mechanism 30 and the discharging mechanism 40 intersect the preset axis a, the two closing mechanisms 20 are symmetrically arranged about the preset axis a, and the feeding mechanism 30 and the discharging mechanism 40 are also symmetrically arranged about the preset axis a. The symmetrical layout improves the symmetry and repeatability of the feeding and discharging actions and the closing action of the door plate 21, simplifies the programming of the motion control program, and only needs a set of logic for one station, which can be copied to another station by rotating 180°, thereby reducing the complexity of debugging and maintenance, and the symmetrical layout also improves the aesthetic appearance of the space layout.

[0050] In some embodiments, the box 11 is a cylindrical structure, and the central axis of the box 11 is configured as the preset axis a. By setting the box 11 as a cylindrical structure, the soundproof cavity 113 in the box 11 is also a cylindrical structure. Unlike a square box 11 with corners, the cylindrical inner cavity does not have sharp angles, which can effectively reduce the distortion of sound waves, the formation of standing waves, and unnecessary reflections, making the sound field distribution in the soundproof cavity 113 more uniform and stable, and greatly improving the accuracy of test data.

[0051] In addition, the cylindrical box 11 and its rotating mode naturally adapt to the central radial layout with the preset axis a as the core, and the feeding mechanism 30, the discharging mechanism 40, and the two closing mechanisms 20 can be compactly arranged around the box 11 along the circumferential tangent direction of the box 11. This layout eliminates the "dead corner" space that is difficult to utilize in traditional linear or right-angle layouts, making the utilization rate of the test equipment in three-dimensional space reach the highest, and the overall structure is very compact and regular, greatly saving the floor area of the test equipment.

[0052] In some embodiments, as shown in FIG. 6, the feeding mechanism 30 and the discharging mechanism 40 are arranged on the same side of the box 11, and the two closing mechanisms 20 are arranged on the opposite side of the box 11. Figure 6As shown, the test assembly 12 comprises a plurality of test elements 121, each of which is used to test different parameters of the material 200; the test mechanism 10 further comprises a clamping structure 14 arranged in the soundproof cavity 113, the clamping structures 14 are spaced apart and each of the clamping structures 14 corresponds to each of the test elements 121; the clamping structure 14 comprises a linear adjustment assembly and a rotating piece 142 rotatably connected to the linear adjustment assembly, the test element 121 is connected to the rotating piece 142, the linear adjustment assembly is used to drive the rotating piece 142 to move linearly to adjust the position of the test element 121, and the rotating piece 142 is used to adjust the orientation of the test element 121 relative to the material 200.

[0053] Understandably, by adjusting the linear movement of the test element 121, the distance between the test element 121 and the part to be tested of the mobile phone can be accurately controlled, so as to meet the requirements of different test standards and ensure the repeatability of the test results, and by adjusting the rotation of the test element 121, the orientation and angle of the test element 121 can be accurately changed to ensure that the sound wave energy is transmitted in the best path, avoid acoustic attenuation and signal distortion caused by angle deviation, so that the most real and accurate audio signal can be collected, and the accuracy of the test is further improved.

[0054] Specifically, when the material 200 is a mobile phone, the plurality of test assemblies 12 comprise a test microphone and an artificial mouth, the test microphone is close to the loudspeaker inside the mobile phone, the loudspeaker inside the mobile phone plays the audio signal from the inside of the mobile phone, and the test microphone can receive the sound emitted by the loudspeaker of the mobile phone and test it, so as to detect the performance of the loudspeaker of the mobile phone; and the artificial mouth can simulate the sound characteristics of the human mouth and play test audio signals to the microphone of the mobile phone to be tested, so as to detect the microphone of the mobile phone to be tested. Therefore, the test assembly 12 of the embodiment of the present application can simultaneously complete the performance collection and analysis of the microphone and the loudspeaker of the mobile phone in one test process, and comprehensively and automatically test the audio performance of multiple parts of the mobile phone at the same time or sequentially in one closed test period, which greatly shortens the test time, reduces the number of equipment clamping, test process starting and repeated operations, and significantly reduces the time cost and labor cost.

[0055] Alternatively, the linear adjustment assembly comprises a transversely extending horizontal rod 1411, a connecting block 1412 slidably connected to the horizontal rod 1411, and a vertical rod 1413 connected to the connecting block 1412 and extending in the vertical direction, the rotating piece 142 is rotatably connected to the bottom end of the vertical rod 1413 and clamps the test element 121, so as to drive the test element 121 to rotate. In addition, scales are arranged on the horizontal rod 1411 and the connecting block 1412, so as to facilitate adjustment according to the scales and improve the consistency and accuracy of adjustment.

[0056] The application further provides a mobile phone production line, which comprises the test device.

[0057] To sum up, the test device provided by the application can switch the box body 11 between the first position state and the second position state by rotating the box body 11 around the preset axis a. The box body 11 is first rotated to the first position state, at which time the first opening 111 is in butt joint with the feeding mechanism 30. The feeding mechanism 30 conveys the material 200 into the sound insulation cavity 113 through the first opening 111 to complete the feeding. Then, the box body 11 is rotated to the second position state, at which time the first opening 111 corresponds to the door plate 21. At this time, since the first opening 111 and the door plate 21 are staggered with the feeding mechanism 30, the driving member 22 can drive the door plate 21 to move towards the first opening 111 and close the first opening 111 without any obstruction, avoiding the interference of the feeding mechanism 30 on the sliding path of the door plate 21 and ensuring that the first opening 111 is closed, so that a reliable sound insulation environment can be constructed for the material 200 test, improving the accuracy of the test.

[0058] The above is only an optional embodiment of the application and is not used to limit the application. The application can have various changes and modifications for those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the application shall be included in the scope of the claims of the application.
