Description

Technical Field

[0001] This invention relates to the field of shell inspection technology, and in particular to a microphone shell impact device and method. Background Technology

[0002] To verify the protective effect of the microphone housing, existing testing devices can simulate the impact force in scenarios such as accidental drops to verify whether the housing structure can effectively protect internal sensitive components (such as microphone heads, circuit boards, etc.) from physical damage, ensuring that the product can still maintain normal function and performance in various real-world scenarios.

[0003] Existing microphone shell impact resistance testing devices typically consist of an impact testing machine, high-precision sensors (such as a force hammer and microphone sensors), a data acquisition system (such as an LMS dynamic signal analyzer), and processing software (such as Matlab). The testing process includes: first, fixing the microphone shell to the test platform, applying a simulated drop force using a force hammer, and simultaneously acquiring the sound pressure signal and structural vibration data of the shell under stress; then, using spectrum analysis technology to process the signals, assessing whether the shell develops cracks, deformations, or damage to internal components (such as diaphragms and circuit boards) under impact, and verifying whether it can maintain stable core performance indicators such as sensitivity and frequency response; finally, by comparing the performance parameters before and after the test, determining whether the impact resistance meets industry standards.

[0004] Since the state of the microphone before it falls greatly affects the final test results, most existing testing devices require operators to manually adjust the clamping and fixing state of the microphone shell before impacting it with a set hammer. This makes it impossible to quickly and accurately adjust the drop pattern of the microphone test sample according to the actual test situation when simulating the microphone falling on its own, which is very inconvenient in actual testing. Summary of the Invention

[0010] The adjusting component includes a fixed gear ring, a driving gear shaft, an adjusting gear, and an adjusting motor. The fixed gear ring is fixedly sleeved on the flipping bracket.

[0012] The clamping component further includes a fitting gear, a rotating gear shaft, and a rotating motor. The fitting gear is fixedly fitted onto the rotating bracket. The gear on the rotating gear shaft meshes with the fitting gear, and the rotating gear shaft is rotatably mounted on the extension frame. The output shaft of the rotating motor is connected to the rotating gear shaft, and the rotating motor is fixedly mounted on the extension frame.

[0013] The detection assembly further includes an ejector plate, a lead screw ejector mechanism, a sealing component, and a guide component. The ejector plate is slidably mounted on the bottom of the main detection box.

[0016] A microphone housing impact method, employing the aforementioned microphone housing impact device, includes the following steps.

[0017] The microphone subject to be tested is clamped by the clamping component and transmitted to the side of the main detection box. Then, the lifting drive mechanism drives the lifting plate to move up so as to lift the clamped microphone subject to be tested to a certain height.

[0018] After the lifting plate raises the microphone subject to be tested, which is held by the clamping member, to a specified height, the clamping member then transfers the microphone subject to be tested into the main testing box.

[0019] After the microphone to be tested is clamped, the lifting drive mechanism drives the lifting plate to adjust the drop height, and at the same time, the clamping component adjusts the actual state of the microphone to be tested before the drop.

[0020] After completing the clamping state of the microphone subject to be tested and the preparation work before the fall, the clamping component releases the clamped microphone subject to be tested, and then the microphone subject to be tested will fall freely.

[0021] After the microphone subject to be tested falls to the bottom of the main testing box, the impact image of the microphone subject to be tested is analyzed and judged by the shooting device set in the main testing box, and then the final detection structure is determined by the sensing mechanism set inside the microphone subject to be tested.

[0022] This invention discloses a microphone housing impact device and method. In actual operation, the clamping member clamps the microphone to be tested, which is transferred to the side of the main detection box. Then, the lifting drive mechanism drives the lifting plate to move upward, so as to raise the clamped microphone to be tested to a certain height. After the lifting plate raises the microphone to be tested held by the clamping member to the designated height, the clamping member transfers the microphone to be tested into the main detection box. After clamping the microphone to be tested, the lifting drive mechanism drives the lifting plate to adjust the drop height. At the same time, the clamping member adjusts the actual state of the microphone to be tested before the drop. After the microphone sample is clamped and prepared for the drop, the clamping component releases the microphone sample, allowing it to fall freely. Once the microphone sample hits the bottom of the main testing box, the imaging device inside the main testing box analyzes and judges the impact of the fall. Then, combined with the sensing mechanism inside the microphone sample, the final detection structure is determined. This allows the microphone sample to be automatically clamped by the provided component, and the drop pattern of the sample can be automatically adjusted according to the actual operation, making actual testing more convenient.

Detailed Implementation

[0035] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0036] In the description of this invention, it should be understood that "a plurality of" means two or more, unless otherwise explicitly specified.

[0037] Please see Figures 1 to 9This invention provides a microphone shell impact device and method, comprising a detection main box 101, a shooting device 102, and a detection component. The detection component includes a lifting plate 103, a side-shifting bracket 104, a lifting drive mechanism 105, a side-shifting drive mechanism 106, a clamping component, and a bottom-changing component. The clamping component includes a flipping bracket 201, an extension bracket 202, a lead screw telescopic mechanism 203, an adjusting component, and a clamping component. The bottom-changing component includes a clamping bracket 301, a lead screw removal mechanism 302, and an impact base plate 303. The adjusting component includes a fixed gear ring 401, a driving gear shaft 402, an adjusting gear 403, and an adjusting motor 404. The clamping component includes a rotating... The device comprises a movable bracket 501, a rotating bracket 502, a rotating motor 503, a clamping plate 504, and a bidirectional clamping mechanism 505. The clamping components also include a fitted gear 506, a rotating gear shaft 507, and a rotating motor 508. The aforementioned solution solves the problem that the state of the microphone before it falls greatly affects the final detection result. Therefore, most existing detection devices require operators to manually adjust the clamping and fixing state of the microphone shell before impacting it with a set hammer. This makes it impossible to quickly and accurately adjust the drop pattern of the microphone test sample according to the actual detection situation when simulating the microphone falling on its own, which is very inconvenient in actual testing.

[0038] Furthermore, the imaging device 102 is fixedly mounted on the detection main box 101, the lifting plate 103 is slidably mounted on the detection main box 101, the side-shifting bracket 104 is slidably mounted on the lifting plate 103, the lifting drive mechanism 105 is disposed on the detection main box 101 for driving the lifting plate 103, the side-shifting drive mechanism 106 is disposed on the lifting plate 103 for driving the side-shifting bracket 104, the clamping component is disposed on the side-shifting bracket 104 for clamping the microphone sample to be tested, and the bottom-changing component is disposed at the bottom of the detection main box 101 for changing the bottom plate of the detection main box 101.

[0039] Specifically, the bottom of the main testing box 101 is provided with a corresponding shielding structure to cover the debris that explodes after the microphone subject to be tested falls, making it convenient for operators to clean and sweep afterward. The bottom of the main testing box 101 is provided with the shooting device 102, which is used to shoot and record the fall of the microphone subject to be tested, making it convenient for operators to analyze and judge the impact of the fall of the microphone subject to be tested.

[0040] The detection main box 101 is provided with corresponding connecting brackets on both sides, and the lifting plate 103 is slidably mounted on the connecting brackets. The lifting drive mechanism 105 consists of two drive screws and a drive mechanism that synchronously drives the two drive screws to rotate. The top of each of the two screws of the lifting drive mechanism 105 is provided with a bevel gear. The two bevel gears rotate synchronously through a bevel gear shaft with two bevel gears. At the same time, the lifting drive mechanism 105 is also provided with a corresponding motor to drive the bevel gear shaft to rotate. Thus, when the screws on both sides rotate synchronously, the lifting plate 103 connected to the two screws will move up and down under the drive of the screws, so that the lifting plate 103 can drive the corresponding mechanism to move up and down.

[0041] The lateral shift bracket 104 is slidably mounted on the lifting plate 103. The lateral shift bracket 104 is driven by the lateral shift drive mechanism 106, which consists of a lead screw and a motor. The motor drives the lead screw to rotate, thereby causing the lateral shift bracket 104 to slide on the lifting plate 103.

[0042] In actual operation, the microphone to be tested, transmitted to the side of the main detection box 101, is clamped by the clamping component. Then, the lifting drive mechanism 105 drives the lifting plate 103 to move upward, so as to raise the clamped microphone to be tested to a certain height. After the lifting plate 103 raises the microphone to be tested held by the clamping component to the designated height, the clamping component transfers the microphone to be tested into the main detection box 101. After clamping the microphone to be tested, the lifting drive mechanism 105 drives the lifting plate 103 to adjust the drop height. At the same time, the clamping component adjusts the actual state of the microphone to be tested before the drop. After the microphone sample is clamped and prepared for the fall, the clamping component releases the microphone sample, allowing it to fall freely. Once the microphone sample hits the bottom of the main testing box 101, the imaging device 102 inside the main testing box 101 analyzes and judges the impact of the fall. Then, combined with the sensing mechanism inside the microphone sample, the final detection structure is determined. This allows the microphone sample to be automatically clamped by the provided component, and the drop pattern of the sample can be automatically adjusted according to the actual operation, making the actual testing more convenient.

[0043] Furthermore, the flip bracket 201 is rotatably mounted on the lateral shift bracket 104; the extension bracket 202 is slidably mounted on the flip bracket 201; the lead screw telescopic mechanism 203 is disposed within the flip bracket 201 and is used to drive the extension bracket 202; the adjusting component is connected to the lateral shift bracket 104 and is used to drive the flip bracket 201; the clamping component is connected to the extension bracket 202 and is used to clamp the microphone sample to be tested.

[0044] Furthermore, the fixed gear ring 401 is fixedly sleeved on the flipping bracket 201; the gear on the driving gear shaft 402 meshes with the fixed gear ring 401, and the driving gear shaft 402 is rotatably mounted on the side-shifting bracket 104; the adjusting gear 403 meshes with the gear on the driving gear shaft 402, and the adjusting gear 403 is rotatably mounted on the side-shifting bracket 104; the output shaft of the adjusting motor 404 is connected to the adjusting gear 403, and the adjusting motor 404 is fixedly mounted on the side-shifting bracket 104.

[0045] In this embodiment, the flip bracket 201 is rotatably mounted on the side-shifting bracket 104, and the extension bracket 202 is slidably mounted on the side of the flip bracket 201. The extension bracket 202 is driven by the lead screw telescopic mechanism 203. The lead screw telescopic mechanism 203 has the same structural principle as the side-shifting drive mechanism 106. By rotating the flip bracket 201 on the side-shifting bracket 104, the microphone subject to be tested after clamping can be significantly adjusted, so as to quickly transfer the microphone subject to be tested located outside the main detection box 101 into the main detection box 101. At the same time, by rotating the flip bracket 201 on the side-shifting bracket 104 and sliding the side-shifting bracket 104 on the flip bracket 201, the clamping range of the microphone subject to be tested can also be expanded to a certain extent.

[0046] The rotating bracket 201 is fitted with a fixed gear ring 401 on its outer side. The gear plate on the outer side of the fixed gear ring 401 meshes with the gear of the driving gear shaft 402. The gear on the driving gear shaft 402 also meshes with the adjusting gear 403. The adjusting gear 403 is driven by the adjusting motor 404 so that the adjusting gear 403 can be driven to rotate. Then, the rotation of the adjusting gear 403 drives the driving gear shaft 402 and the fixed gear ring 401 to rotate, thus driving the rotating bracket 201.

[0047] When the two clamping plates 504 on the rotating bracket 502 clamp the microphone subject to be tested, the falling shape of the clamped microphone subject to be tested can be adjusted by the corresponding movements of the flip bracket 201, the rotating bracket 501 and the rotating bracket 502. At the same time, the falling situation of the microphone subject to be tested during movement can be simulated by the corresponding movements of the lifting plate 103 and the side-shifting bracket 104.

[0048] Furthermore, the mounting bracket 301 is slidably mounted on the bottom of the main detection box 101; the lead screw removal mechanism 302 is disposed at the bottom of the main detection box 101 and is used to drive the mounting bracket 301; the impact base plate 303 is mounted on the mounting bracket 301.

[0049] In this embodiment, the mounting bracket 301 is adapted to the bottom guide groove of the detection main box 101. The mounting bracket 301 is driven by the lead screw removal mechanism 302. The lead screw removal mechanism 302 has the same structural principle as the side-shifting drive mechanism 106. The surface of the mounting bracket 301 is provided with mounting slots that cooperate with the mounting platforms on both sides of the impact base plate 303, so that the operator can directly mount the impact base plate 303 of different materials onto the surface of the mounting bracket 301.

[0050] When conducting impact resistance testing on the microphone subject, the material of the base plate that is impacted by the microphone subject directly affects the drop impact result. Therefore, after the mounting bracket 301 is removed from the bottom of the main testing box 101 by the lead screw removal mechanism 302, the operator can attach the impact base plate 303 of different materials to the top of the mounting bracket 301 according to the actual situation, so as to more flexibly and comprehensively simulate the actual drop situation of the microphone.

[0051] Furthermore, the rotating bracket 501 is rotatably mounted on one side of the extension bracket 202; the rotating bracket 502 is rotatably mounted on the rotating bracket 501; the output shaft of the rotating motor 503 is connected to the rotating bracket 502, and the rotating motor 503 is fixedly mounted on the rotating bracket 501; the two clamping plates 504 are slidably mounted on the rotating bracket 502; and the bidirectional clamping mechanism 505 is disposed on the rotating bracket 502 for driving the two clamping plates 504.

[0052] Furthermore, the insert gear 506 is fixedly sleeved on the rotating bracket 501; the gear on the rotating gear shaft 507 meshes with the insert gear 506, and the rotating gear shaft 507 is rotatably mounted on the extension frame 202; the output shaft of the rotating motor 508 is connected to the rotating gear shaft 507, and the rotating motor 508 is fixedly mounted on the extension frame 202.

[0053] In this embodiment, the rotating bracket 501 is rotatably mounted on the extension bracket 202, and the rotating bracket 502 is rotatably mounted on the rotating bracket 501. The rotating bracket 502 is driven by the rotating motor 503. Two clamping plates 504 are slidably mounted on the rotating bracket 502. Friction pads are provided on the clamping side of each clamping plate 504 to ensure stable and secure clamping of the microphone subject to be tested. The two clamping plates 504 are driven by the bidirectional clamping mechanism 505. The bidirectional clamping mechanism 505 consists of lead screws with opposite thread directions on both sides and a motor that drives the corresponding lead screws to rotate. The two clamping plates 504 respectively cooperate with the threads on both sides of the lead screw in the bidirectional clamping mechanism 505. When the motor in the bidirectional clamping mechanism 505 drives the corresponding motor to rotate, the lead screw in the bidirectional clamping mechanism 505 can drive the two clamping plates 504 to expand to both sides or move closer to the center, thereby achieving clamping and limiting of the microphone subject to be tested.

[0054] The rotating bracket 501 has a fixedly fitted gear 506 on its rotating connecting rod. The fitted gear 506 meshes with a gear on the rotating gear shaft 507. The rotating gear shaft 507 is driven by the rotating motor 508. When the rotating motor 508 drives the rotating gear shaft 507 to rotate, the fitted gear 506 will drive the rotating bracket 501 to rotate under the drive of the rotating gear shaft 507.

[0055] The rotation of the rotating bracket 501 on the extension frame 202, in conjunction with the rotation of the rotating bracket 502 on the rotating bracket 501, allows for corresponding adjustments to the clamping state of the microphone subject under test in the clamping state. This enables the operator to adjust the clamping state of the microphone subject under test before it falls according to the actual testing conditions.

[0056] Preferably, the detection assembly provided by the present invention further includes an ejector plate 601, a lead screw ejector mechanism 602, a sealing component, and a guide component. The sealing component includes a side sealing plate 701, a lifting lead screw 702, and a lifting motor 703. The guide component includes a fixed bracket 801, a swing guide plate 802, and a swing motor 803.

[0057] Furthermore, the ejector plate 601 is slidably mounted on the bottom of the main detection box 101; the lead screw ejector mechanism 602 is disposed at the bottom of the main detection box 101 and is used to drive the ejector plate 601; the sealing member is connected to the main detection box 101 and is used to adjust the bottom side opening of the main detection box 101; the sorting member is disposed on one side of the bottom side opening of the main detection box 101 and is used to sort and guide the ejected microphone sample to be tested.

[0058] Furthermore, the side sealing plate 701 is slidably installed on one side of the bottom side opening of the main detection box 101; the lifting screw 702 is threadedly connected to the side sealing plate 701 and rotatably installed on one side of the main detection box 101; the output shaft of the lifting motor 703 is connected to the lifting screw 702, and the lifting motor 703 is fixedly installed on the main detection box 101.

[0059] In this embodiment, the inner side of the detection main box 101 is provided with the ejector plate 601. The ejector plate 601 is adapted to the side shift grooves provided on both sides of the bottom of the detection main box 101 by the extension bosses provided on both sides. The extension bosses on both sides of the ejector plate 601 cooperate with the guide post of the detection main box 101 and the lead screw ejector mechanism 602 respectively. The lead screw ejector mechanism 602 has the same structural principle as the side shift drive mechanism 106, so that the ejector plate 601 can be driven to slide at the bottom of the detection main box 101 by the lead screw ejector mechanism 602. Then, the microphone subject to be tested on the impact base plate 303 and the debris exploded due to the drop impact are ejected from the bottom side opening of the detection main box 101 by the sliding of the ejector plate 601.

[0060] The side sealing plate 701 is adapted to the bottom side opening of the main detection box 101 and the guide groove of the main detection box 101. The side sealing plate 701 is threadedly connected to the lifting screw 702. The lifting screw 702 is driven by the lifting motor 703. When the lifting motor 703 drives the lifting screw 702 to rotate, the side sealing plate 701 will slide up and down under the drive of the lifting screw 702, so that the bottom side opening of the main detection box 101 can be controlled by sliding the side sealing plate 701.

[0061] When the microphone subject to be tested needs to be subjected to impact resistance testing inside the main testing box 101, the side sealing plate 701 will cover the bottom side opening of the main testing box 101 to prevent internal debris from falling outside the main testing box 101.

[0062] Furthermore, the fixed bracket 801 is fixedly installed on the side of the detection main box 101 near the side sealing plate 701; the swing guide plate 802 is rotatably installed on the fixed bracket 801; the output shaft of the swing motor 803 is connected to the swing guide plate 802, and the swing motor 803 is fixedly installed on one side of the fixed bracket 801.

[0063] In this embodiment, two fixed brackets 801 are fixed on the main detection box 101. The swing guide plate 802 is rotatably mounted on the fixed brackets 801. The swing guide plate 802 is driven by the swing motor 803. The bottom side opening of the main detection box 101 is provided with an inclined guide platform. One side of the swing guide plate 802 can abut against the bottom of the inclined guide platform. When the push plate 601 pushes the microphone subject to be tested in the main detection box 101 out of the bottom side opening of the main detection box 101, the pushed-out microphone subject to be tested will roll down from above the inclined guide platform of the main detection box 101, and then be guided by the swing guide plate 802. The swing guide plate 802 guides the microphone subject to be tested.

[0064] When one side of the swing guide plate 802 abuts against the bottom of the inclined guide platform, the microphone subject to be tested can roll off the bottom of the swing guide plate 802 under the guidance of the swing guide plate 802. When the swing guide plate 802 is flipped under the drive of the swing motor 803, the microphone subject to be tested that has rolled off the inclined guide platform will roll off between the inclined guide platform and the swing guide plate 802. In this way, different types of microphone subjects to be tested can be sorted and exported by changing the state of the swing guide plate 802.

[0065] Based on the impact resistance test results of different microphone subjects, the qualified and unqualified microphone subjects can be separated and exported by adjusting the state of the swing guide plate 802.

[0066] Please see Figure 10 A microphone housing impact method, employing the aforementioned microphone housing impact device, includes the following steps.

[0067] S1: The microphone subject to be tested, transmitted to the side of the main detection box 101, is clamped by the clamping component, and then the lifting plate 103 is moved upward by the lifting drive mechanism 105 so as to lift the clamped microphone subject to be tested to a certain height.

[0068] S2: After the lifting plate 103 lifts the microphone subject to be tested held by the clamping member to a specified height, the clamping member then transfers the microphone subject to be tested into the main testing box 101;

[0069] S3: After clamping the microphone subject to be detected, the lifting drive mechanism 105 drives the lifting plate 103 to adjust the drop height, and at the same time, the clamping component adjusts the actual state of the microphone subject to be detected before the drop.

[0070] S4: After completing the clamping state of the microphone subject to be tested and the preparation work before the fall, the clamping component is used to release the clamped microphone subject to be tested, and then the microphone subject to be tested will fall freely.

[0071] S5: After the microphone subject to be tested falls to the bottom of the main detection box 101, the camera 102 installed in the main detection box 101 analyzes and judges the impact image of the microphone subject to be tested falling, and then combines the sensing mechanism installed inside the microphone subject to be tested to determine the final detection structure.

[0072] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
