[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] The directional terms mentioned in this utility model, such as "up", "down", "front", "back", "left", "right", "inner", "outer", "side", "top" and "bottom", are only for reference to the orientation of the accompanying drawings. The directional terms used are for the purpose of explaining and understanding this utility model, and are not intended to limit this utility model.

[0033] The terms "first" and "second" in this utility model are used for descriptive purposes only and should not be construed as indicating or implying relative importance, nor as a restriction on the order of events.

[0034] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, a connection can be a detachable connection or a connection of an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0035] Current microphone products typically use a single device with a single function for testing. This results in limited testing capabilities and low efficiency, making it difficult to meet diverse user testing needs.

[0036] Furthermore, existing microphone testing equipment typically requires a certain testing time, and manual or other work processes need to wait for the test to complete, extending the overall testing cycle and making it difficult to meet the high-efficiency requirements of mass production.

[0037] The following is a preferred embodiment of a microphone testing device with flexibly switchable test modules that can solve the above-mentioned technical problems provided by this utility model.

[0038] Please refer to Figure 1 ,in Figure 1 This is a schematic diagram of the microphone testing device with flexibly switchable test modules according to this utility model. In the figure, units with similar structures are represented by the same reference numerals.

[0039] This embodiment provides a microphone testing device with flexibly switchable test modules, which includes: a base platform 11, a mounting platform 21, a material preparation device 12, a transfer platform 14, a material unloading device 13, a test module 15, a positioning camera 16, a barcode scanner 1A, a defective product placement platform 17, and a loading and unloading robot.

[0040] The loading and unloading robot in this embodiment includes a first loading and unloading robot 181 and a second loading and unloading robot 182.

[0041] The material preparation device 12 and the unloading device 13 are sequentially arranged on one side of the base platform 11, and the mounting platform 21 is arranged on the other side of the base platform 11. The test module 15 is detachably mounted on the mounting platform 21. The first loading / unloading robot 181 is arranged between the test module 15 and the material preparation device 12, the second loading / unloading robot 182 is arranged between the test module 15 and the unloading device 13, the transfer platform 14 is arranged between the first loading / unloading robot 181 and the second loading / unloading robot 182, the barcode scanner 1A is arranged at the gripping end of the first loading / unloading robot 181, the positioning camera 16 is arranged on the base platform 11, and the defective product placement platform 17 is arranged on the side of the second loading / unloading robot 182 away from the first loading / unloading robot 181.

[0042] Please compare and refer to the above. Figure 1 and Figure 6 In this embodiment, the multiple test modules 15 can be FR&SL test module 15a, ICT test module 15b, or a combination of FR&SL test module 15a and ICT test module 15b.

[0043] The FR&SL test module 15a is used to perform frequency response and directional pattern tests, which are important indicators for evaluating microphone performance.

[0044] Frequency response testing measures the changes in the microphone's output electrical signal across different frequency bands by inputting sound signals of varying frequencies, thus determining the accuracy of its sound reproduction. For example, human voices are primarily concentrated in the 300-3000Hz frequency range; if a microphone's output is stable within this range, it indicates good frequency response performance.

[0045] The directivity pattern test involves inputting the same sound signal from different directions and measuring the difference in the output electrical signal in each direction to create a directivity diagram. For example, an omnidirectional microphone picks up sound evenly in all directions, while a cardioid microphone is only sensitive in a specific direction.

[0046] The ICT Test Module 15b is used for comprehensive testing of the electrical functionality and soldering quality of microphone components.

[0047] Please refer to Figure 6In this embodiment, the mounting platform 21 includes a support base 211, a platform plate 212, and limiting blocks. The support base 211 is fixedly connected to the base platform 11. The platform plate 212 is slidably mounted on the support base 211, and the sliding direction of the platform plate 212 is parallel to the top surface of the base platform 11. The distance between the test module 15 and the loading / unloading robot is adjusted by sliding the platform plate 212. The limiting blocks are adjustablely mounted on the platform plate 212, and multiple limiting blocks respectively press against the four sides of the test module 15. The limiting blocks stably limit the test module 15 on the platform plate 212, preventing it from moving laterally. At the same time, the test module 15 can be stably placed on the platform plate 212 under its own weight. The test module 15 can be easily replaced and mounted on the mounting platform 21.

[0048] Specifically, the multiple limit blocks include fixed limit blocks 2131 and movable limit blocks 2132. Movable limit blocks 2132 are provided on the side of the two test modules 15 on each platform unit 111 that are far apart from each other, and on the side of the test module 15 that is away from the loading and unloading robot. Fixed limit blocks 2131 are provided on the other sides of the test module 15.

[0049] The fixed limiting block 2131 is fixedly connected to the platform plate 212 by screws. When the test module 15 is placed on the platform plate 212, one or both sides of the test module 15 are respectively positioned and contacted with the fixed limiting block 2131.

[0050] One end of the movable limiting block 2132 is rotatably connected to the platform plate 212 via a rotating shaft 21321, which is perpendicular to the platform plate 212. The other end of the movable limiting block 2132 is threadedly connected to a limiting screw 21322, which passes through the movable limiting block 2132. After both sides of the test module 15 are in positional contact with the fixed limiting block 2131, the limiting screw 21322 is loosened. Then, the movable limiting block 2132 is rotated around the rotating shaft 21321 to make it contact the test module 15. Finally, the limiting screw 21322 is tightened to fix the position of the movable limiting block 2132, ensuring that the movable limiting block 2132 stably compresses and limits the test module 15.

[0051] Optionally, the limiting screw 21322 is inclined to the platform plate 212, with the top of the limiting screw 21322 closer to the test module 15. In this way, during the tightening of the limiting screw 2132, the movable limiting block 2132 can move closer to the test module 15 and exert a compressive force on the test module 15, improving the stability of the compressive limiting force exerted by the movable limiting block 2132 on the test module 15.

[0052] The bottom of the limiting screw 21322 can be configured as a semi-circular head structure so that the limiting screw 21322 can be tilted and stably contact the platform plate 212.

[0053] In this embodiment, the bottom of the test module 15 is provided with multiple elastic support blocks to improve the vibration resistance of the test module 15.

[0054] Please refer to Figure 1 and Figure 2 In this embodiment, the base platform 11 is formed by two platform units 111 arranged side by side, and there are four test modules 15. Two test modules 15 are set on each platform unit 111. A first loading and unloading robot 181 and a material preparation device 12 are set on one platform unit 111, and a second loading and unloading robot 182 and a material unloading device 13 are set on the other platform unit 111.

[0055] The base platform 11 also includes a connecting block 112, a fixing column 113 and a locking block 114, with two platform units 111 being the first platform unit and the second platform unit, respectively.

[0056] One end of the connecting block 112 is fixedly connected to the top surface of the first platform unit, and the other end of the connecting block 112 extends to the top surface of the second platform unit. A connecting groove 1121 is vertically provided through the end of the connecting block 112 near the second platform unit. The connecting groove 1121 laterally extends through the side of the connecting block 112 away from the first platform unit, forming an insertion interface. A fixing post 113 is provided on the top surface of the second platform unit. When the first and second platform units are joined, by moving the first and second platform units closer together, the fixing post 113 can be fitted from the insertion interface into the connecting groove 1121. Then, a locking block 114 is connected to the side of the connecting block 112 where the insertion interface is located, and the locking block 114 restricts the fixing post 113 within the connecting groove 1121. This achieves a stable joining of the first and second platform units.

[0057] The stable engagement of the connecting block 112 and the fixing column 113 can lock the lateral movement between the first platform unit and the second platform unit, while the first platform unit and the second platform unit will not move vertically under their own gravity, and the fixing column 113 will not disengage from the connecting groove 1121.

[0058] In this embodiment, both platform units 111 are provided with connection holes for connecting to the transfer platform 14, or to the unloading platform and the defective product placement platform 17. That is, the two platform units 111 can be spliced ​​together as needed, in which case the transfer platform 14 is set between the two platform units 111. Alternatively, a single platform unit 111 can be used, in which case the connection between the original transfer platform 14 and the unloading platform and the defective product placement platform 17 can be replaced, offering high flexibility.

[0059] Please refer to Figure 1 and Figure 3 In this embodiment, the first loading / unloading robot 181 and the second loading / unloading robot 182 have the same structure, and both include a connecting plate 1811, a lifting cylinder 1812, a lifting plate 1813, and a rotating suction assembly 1814.

[0060] A lifting cylinder 1812 is installed at each end of one side of the connecting plate 1811. The output end of the lifting cylinder 1812 is connected to the lifting plate 1813. The rotary suction assembly 1814 is connected to the lifting plate 1813. The barcode scanner 1A is installed on one side of the connecting plate 1811 and located between the two rotary suction assemblies 1814. The first loading / unloading robot 181 and the second loading / unloading robot 182 can grab two microphone products to be tested at a time. Before grabbing, the barcode scanner 1A scans the microphone products to be tested.

[0061] Please refer to Figure 4 In this embodiment, the material preparation device 12 includes a first transfer robot 121, an empty material tray buffer platform 122 with lifting and lowering, and a loading platform 123. The empty material tray buffer platform 122 and the loading platform 123 are arranged side by side, and the first transfer robot 121 is slidably positioned above the empty material tray buffer platform 122 and the loading platform 123. Multiple material trays can be stacked on both the empty material tray buffer platform 122 and the loading platform 123. After the products in the material trays on the loading platform 123 are all picked up, the first transfer robot 121 picks up the empty material trays on the loading platform 123 and transfers them to the empty material tray buffer platform 122.

[0062] The structure of the unloading device 13 is basically the same as that of the material preparation device 12, so no reference numerals are used for the unloading device 13. The unloading device 13 includes a second transfer robot, a lifting and lowering full-tray buffer platform, and a unloading platform. The full-tray buffer platform and the unloading platform are arranged side by side, and the second transfer robot is slidably positioned above the full-tray buffer platform and the unloading platform. Multiple trays can be stacked on both the full-tray buffer platform and the unloading platform. After the trays on the unloading platform are full of products, the second transfer robot grabs the full-load trays on the unloading platform and transfers them to the full-tray buffer platform.

[0063] Please refer to Figure 4 The base platform 11 has multiple sensors 124 on its top surface, and two sensors 124 are installed diagonally on the empty tray buffer platform 122, the loading platform 123, the full tray buffer platform, and the unloading platform. The controller controls the raising and lowering of the empty tray buffer platform 122, the loading platform 123, the full tray buffer platform, and the unloading platform based on the signals from the sensors 124, ensuring that the topmost tray remains in a fixed position.

[0064] Furthermore, multiple positioning strips 125 are connected to the base platform 11. The positioning strips 125 extend along the lifting direction of the empty tray buffer platform 122, the loading platform 123, the full tray buffer platform, and the unloading platform. An loading / unloading opening is provided on one side of the base platform 11. Positioning strips 125 are provided on the other three sides of the empty tray buffer platform 122, the loading platform 123, the full tray buffer platform, and the unloading platform that are away from the loading / unloading opening. The positioning strips 125 are used to position the stacked trays.

[0065] It should be noted that a shorter positioning strip 126 can also be provided on the side of the base platform 11 near the loading and unloading opening, with the short positioning strip 126 avoiding the loading and unloading opening. The short positioning strip 126, together with the positioning strips 125 on the other three sides, can form a positioning system for the four sides of the material tray.

[0066] It should also be noted that the bottom end of the short positioning bar 126 can be provided with an arc-shaped guide end, and the bottom end of the arc-shaped guide end is further away from the material tray than the top end.

[0067] In this embodiment, the positioning camera 16 is embedded inside the top surface of the base platform 11, and the positioning camera 16 will not interfere with the activities of the first loading and unloading robot 181.

[0068] The microphone testing device with flexibly switchable test modules in this embodiment also includes a barcode defective product placement platform 19. The barcode defective product placement platform 19 is located on the side of the first loading and unloading robot 181 away from the second loading and unloading robot 182. When there is a product with barcode defect, the first loading and unloading robot 181 directly places the product on the barcode defective product placement platform 19.

[0069] The working principle of this utility model is as follows: First, multiple trays containing microphone products to be tested are stacked on the loading platform 123, and then multiple empty trays are stacked on the unloading platform. The first loading / unloading robot 181 grabs the microphone product to be tested from the trays on the loading platform 123 and scans the barcode of the microphone product to be tested completely. Then, the first loading / unloading robot 181 moves the grabbed microphone product to be tested above the positioning camera 16 for taking a picture. Based on the picture information from the positioning camera 16, the first loading / unloading robot 181 adjusts the position of the grabbed microphone product to be tested, and then places the microphone product to be tested into the test module 15 of the first platform unit for testing.

[0070] During the test, the first loading and unloading robot 181 grabs the microphone product to be tested from the tray of the loading platform 123 and scans the barcode of the microphone product to be tested. Then, the first loading and unloading robot 181 moves the grabbed microphone product to be tested above the positioning camera 16 to take a picture. Based on the picture information of the positioning camera 16, the first loading and unloading robot 181 adjusts the position of the grabbed microphone product to be tested and then places the microphone product to be tested on the transfer platform 14.

[0071] The second loading / unloading robot 182 picks up the microphone product to be tested from the transfer platform 14 and places it into the test module 15 of the second platform unit for testing.

[0072] After the test module 15 of the first platform unit is completed, the first loading and unloading robot 181 grabs the tested product from the test module 15 and places it on the transfer platform 14. The second loading and unloading robot 182 then grabs the tested product from the transfer platform 14 and places it into the empty tray of the unloading platform.

[0073] After the test module 15 of the second platform unit completes the test, the second loading and unloading robot 182 grabs the tested product from the test module 15 of the second platform unit and places it into the empty material tray of the unloading platform. Other components can efficiently utilize the testing time of the test module 15, resulting in high overall work efficiency.

[0074] This completes the process of providing a microphone testing device with flexibly switchable test modules according to this preferred embodiment.

[0075] The microphone testing equipment with flexible test module switching of this preferred embodiment can easily and flexibly set up FR&SL test modules and / or ICT test modules with different test functions on the installation platform. It has high testing flexibility, can meet different testing needs of users, has high work efficiency, and low overall cost.

[0076] In addition, the microphone testing equipment of this utility model with flexible switchable test modules is equipped with a first loading and unloading robot, a second loading and unloading robot, and a transfer platform. When the microphone product to be tested is being tested in the test module, the first loading and unloading robot and the second loading and unloading robot can transfer and transport the microphone product through the transfer platform, which can make efficient use of the test module's testing time and has high overall work efficiency.

[0077] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention.
