Description

Technical Field

[0001] This utility model relates to the field of testing device technology, and in particular to a multifunctional automatic testing device. Background Technology

[0002] In the current home appliance industry, with the continuous advancement of the trend towards smart technology, some high-end air conditioner models integrate advanced voice control functions. This allows users to wake up the air conditioner by voice to adjust cooling and heating modes, play music, and listen to stories. In the air conditioner manufacturing process, components such as the voice module, speaker, and loudspeaker assembly that enable voice control are usually outsourced. Currently, there is a lack of effective testing methods for these outsourced components during the incoming inspection process, making it impossible to test all components to determine their functionality. One existing method for testing these components is to assemble them into the air conditioner's mainboard before testing. This process is not only labor-intensive and time-consuming, but also requires secondary assembly of components such as surface-mount microphones and loudspeakers before final product testing. This post-testing method prevents effective screening of materials in the early stages. If defective materials flow into subsequent processes, it is highly likely to cause product quality abnormalities, leading to problems throughout the entire production batch, resulting in significant cost waste and severely impacting production efficiency and product quality stability.

[0003] Therefore, it is necessary to improve the detection methods of existing voice control components to overcome the shortcomings of existing technologies. Utility Model Content

[0004] To overcome the problems existing in related technologies, the purpose of this utility model is to provide a multifunctional automatic testing device that can be used to test voice module components and other components. It is easy to use, has a wide range of applications, high versatility, and can save testing costs.

[0005] A multifunctional automatic testing device, comprising:

[0006] The test body is equipped with a test bracket, a tray with several product placement positions on the test bracket, a liftable test plate above the tray, several probes for connecting to the products at the bottom of the test plate, and a lifting drive structure for driving the test plate on the test bracket.

[0007] The test body is equipped with several switching switches, which are used to switch between different test modes.

[0008] This device can be used for testing components such as voice module assemblies or patch microphones. During testing, the appropriate auxiliary tools and equipment must first be prepared according to the type of product being tested. For example, to test a voice module assembly, a control terminal (such as a computer or a dedicated test phone) capable of connecting to the testing device and simulating voice command input and feedback reception is required, along with the corresponding testing software. To test a patch microphone, a standard audio signal generator is needed to input audio signals of specific frequencies and intensities to the patch during testing.

[0009] Carefully place the voice module assembly or microphone patch into the corresponding product slot on the tray. For the voice module assembly, ensure that its pins or connectors fit snugly into the positioning structure of the slot to prevent displacement during testing. For the microphone patch, ensure that its positive and negative polarities align with the markings on the slot to guarantee correct probe connection.

[0010] When using this device for testing voice module components, the lifting drive structure is activated, causing the test board to slowly descend. The test board is ensured to descend accurately to the predetermined position, allowing the probes to reliably contact the test points of the voice module component, forming a good electrical connection. At this point, the connection indicator light on the test body is observed to confirm that the electrical connection is normal. The switch on the test body is then switched to the voice module test mode. The internal circuitry of the test body will provide appropriate power and signal input / output channels to the voice module component according to the switched mode. Through the connected control terminal, the test software is opened, and a series of predefined voice commands are sent to the voice module component, such as waking up the voice assistant, querying device status, and performing specific function operations. Simultaneously, the test software receives and analyzes the response signals from the voice module component in real time. Ideally, during the test, the tester can view the test data and results in real time through the test software interface. If any abnormality is found, the test can be paused to check and debug the test device and the voice module component.

[0011] In a preferred embodiment of this utility model, the plurality of product placement positions include a first placement position and a second placement position, the second placement position being disposed on one side of the first placement position, the first placement position being used to support a voice module, and the second placement position being used to support a patch microphone.

[0012] The plurality of probes includes a first probe and a second probe, the first probe corresponding to a first placement position and the second probe corresponding to a second placement position.

[0013] In a preferred embodiment of this invention, a control circuit board is provided inside the test body, and the probe and the switching switch are both electrically connected to the control circuit board.

[0014] In a preferred embodiment of this invention, the test subject is further provided with a speaker and a microphone, both of which are electrically connected to the control circuit board.

[0015] The test unit incorporates a control circuit board, speakers, and microphone, achieving a high degree of integration of testing functions. This design integrates all test-related functional modules into a single test device, significantly reducing the footprint of the testing equipment and the complexity of connections between devices. For example, in small production workshops or laboratories, the saved space can be used to place other production or testing equipment, improving space utilization efficiency.

[0016] Furthermore, the system allows for quick switching between voice module and speaker test modes via a simple toggle switch, eliminating the need for complex equipment reconfiguration and wiring rewiring, thus significantly reducing testing time. For example, in mass production, an efficient testing process can significantly increase the number of products tested per unit time, reducing production costs.

[0017] In a preferred embodiment of this invention, the test body is further provided with a first connection port and a second connection port, both of which are electrically connected to the control circuit board.

[0018] The first and second connection ports provide testing interfaces for the semi-finished speaker. During use, the alligator clips of the speaker's cable are connected to the two ports, and the test mode is switched by toggling a toggle switch, thus enabling testing of the semi-finished speaker. This usage method expands the application scenarios for this multi-functional automatic testing device.

[0019] In a preferred embodiment of this invention, a main control switch is provided on the top of the test body, and the main control switch is used to control the circuit switching of the test body.

[0020] In a preferred embodiment of this utility model, the first placement position includes a placement groove and a contour block disposed on the edge of the placement groove, wherein the contour block is detachably connected to the placement groove.

[0021] The edge of the contour block and the placement groove form the first placement position.

[0022] In a preferred embodiment of this invention, the bottom of the placement groove is provided with a mounting hole, and the contour block is detachably connected to the mounting hole via a connector.

[0023] The combination of detachable contour blocks and placement slots allows for flexible adjustments to accommodate products of varying shapes and sizes. For various voice module components or similar components, regardless of their shape, precise fit can be achieved by replacing the appropriate contour block. This precise fit ensures product stability in its placement position, reducing testing errors caused by product movement or displacement during testing, thereby improving the accuracy of test results. For example, when testing small and irregularly shaped voice modules, specially customized contour blocks can tightly wrap around the product, allowing probes to accurately contact the test points, effectively avoiding erroneous test results due to poor contact.

[0024] Because the profiling blocks can closely match the shape of the product, operators can more easily and quickly place the product in the correct position, improving the convenience and efficiency of testing operations. At the same time, it also reduces the risk of product damage due to improper placement.

[0025] In addition, the presence of the contour block also serves as a foolproof measure, preventing the product to be tested from being misplaced.

[0026] In a preferred embodiment of this utility model, the lifting drive structure includes a wrench and a lifting rod, a guide sleeve is provided on the test bracket, and the lifting rod passes through the guide sleeve in a vertical direction;

[0027] The test bracket is also equipped with a connecting frame, and the wrench is hinged to the connecting frame. The bottom of the wrench is hinged to the top of the lifting rod.

[0028] This embodiment employs a lifting drive structure consisting of a wrench and a lifting rod. The operation is simple and intuitive, requiring no complex electrical controls or hydraulic equipment. Operators can raise and lower the test board simply by manually operating the wrench, reducing the technical requirements and training costs for operators. Compared to some highly automated but structurally complex lifting drive devices, this structure has lower manufacturing costs, reducing investment in testing equipment for enterprises. For example, in small businesses or production environments with strict cost control, this simple lifting drive structure can meet testing needs while effectively reducing equipment procurement and maintenance costs.

[0029] In a preferred embodiment of this invention, a guide rod is provided on the test body, and a guide hole is provided on the test plate for the guide rod to pass through.

[0030] The design of the guide sleeve and guide rod ensures the stability of the lifting rod and test plate during the lifting process. The lifting rod moves vertically along the guide sleeve, which can prevent deviation or swaying during descent, ensuring that the probes at the bottom of the test plate can accurately contact the test points of the product and form a good electrical connection.

[0031] The beneficial effects of this utility model are as follows:

[0032] This utility model provides a multifunctional automatic testing device, which includes a testing body, a testing bracket on the testing body, a tray on the testing bracket, and several product placement positions on the tray. A liftable testing plate is also provided above the tray, and several probes for connecting to the products are provided at the bottom of the testing plate. A lifting drive structure for driving the testing plate is provided on the testing bracket. The testing body is equipped with several switch switches for switching between different testing modes. This device can be applied to the side-viewing process of voice module components and speaker components. In actual use, the voice module component is placed in the placement position, and then the testing plate is pressed down to connect the probes to the voice module component, forming a good electrical connection. Switching to the voice module test mode via the switch allows testing the functional integrity of the voice module component. Alternatively, a microphone patch can be placed in the placement position, similarly connecting the probes on the testing plate to the microphone patch, and switching to the microphone patch test mode allows testing the functional integrity of the microphone patch. This device can test different components, is highly versatile, and easy to use; moreover, it performs functional tests on components before assembly, preventing malfunctioning components from being installed in electrical appliances, thus helping to ensure product quality.

[0040] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0041] In the field of electrical appliances, especially fans and standing heaters, oscillation functions are quite common. The steel ball support assembly, as a key structure connecting the upper and lower parts of the oscillator, plays a crucial role in supporting and ensuring smooth and stable oscillation during product operation. Traditionally, the assembly of the steel ball support assembly relies heavily on manual operation. Operators must manually pick up the steel ball holders (steel ball supports) and then press the steel balls in one by one. This process is labor-intensive and extremely inefficient, with an average assembly time of 8-10 seconds per steel ball support. With the expansion of production scale and the increase in efficiency requirements, this manual assembly method can no longer meet production needs and has become a bottleneck restricting the improvement of production efficiency.

[0042] Based on this, this application provides a multifunctional automatic testing device.

[0043] Example 1

[0044] like Figures 1-5 As shown, this embodiment provides a multifunctional automatic testing device, including:

[0045] The test body 1 is equipped with a test bracket 2, a tray 3 is equipped with a tray 3, and a number of product placement positions are provided on the tray 3; a liftable test plate 4 is also provided above the tray 3, and a number of probes 41 for connecting with the product are provided at the bottom of the test plate 4; the test bracket 2 is equipped with a lifting drive structure 5 for driving the test plate 4.

[0046] The test body 1 is equipped with several switching switches 13, which are used to switch between different test modes.

[0047] This device can be used for testing components such as voice module assemblies or patch microphones 12. During testing, the appropriate auxiliary tools and equipment must first be prepared according to the type of product to be tested. For example, to test a voice module assembly, a control terminal (such as a computer or a dedicated test phone) capable of connecting to the testing device and simulating voice command input and feedback reception must be prepared, and the corresponding testing software must be installed. If testing a patch microphone 12, a standard audio signal generator must be prepared to input audio signals of specific frequencies and intensities to the patch microphone 12 during testing.

[0048] Carefully place the voice module assembly or microphone 12 patch onto the corresponding product placement position on tray 3. For the voice module assembly, ensure that its pins or interfaces fit snugly into the positioning structure of the placement position to prevent displacement during testing. For the microphone 12 patch, ensure that its positive and negative polarity aligns with the markings on the placement position to ensure that probe 41 connects correctly.

[0049] More specifically, when using this device for testing voice module components, the lifting drive structure 5 is activated, causing the test board 4 to slowly descend. This ensures the test board 4 accurately descends to the predetermined position, allowing the probe 41 to reliably contact the test points of the voice module component, forming a good electrical connection. At this time, the connection indicator light on the test body 1 is observed to confirm that the electrical connection is normal. The switch 13 on the test body 1 is then switched to the voice module test mode. The internal circuitry of the test body 1 will provide appropriate power and signal input / output channels to the voice module component according to the switched mode. Through the connected control terminal, the test software is opened, and a series of predefined voice commands are sent to the voice module component, such as waking up the voice assistant, querying device status, and performing specific function operations. Simultaneously, the test software receives and analyzes the response signals from the voice module component in real time. Ideally, during the test, the tester can view the test data and results in real time through the test software interface. If any abnormality is found, the test can be paused to check and debug the test device and the voice module component.

[0050] In this embodiment, the plurality of product placement positions include a first placement position 31 and a second placement position 32. The second placement position 32 is disposed on one side of the first placement position 31. The first placement position 31 is used to carry the voice module, and the second placement position 32 is used to carry the patch microphone 12.

[0051] The plurality of probes 41 include a first probe and a second probe, the first probe corresponding to the first placement position 31 and the second probe corresponding to the second placement position 32.

[0052] In this embodiment, a control circuit board is provided inside the test body 1, and the probe 41 and the switching switch 13 are both electrically connected to the control circuit board.

[0053] In this embodiment, the test body 1 is also provided with a speaker 11 and a microphone 12, both of which are electrically connected to the control circuit board.

[0054] The test unit 1 houses a control circuit board and integrates a speaker 11 and a microphone 12, achieving a high degree of integration of testing functions. This design integrates all test-related functional modules into a single test device, significantly reducing the footprint of the test equipment and the complexity of connections between devices. For example, in small production workshops or laboratories, the saved space can be used to place other production or testing equipment, improving the efficiency of space utilization.

[0055] Furthermore, the system allows for quick switching between voice module and speaker test modes via a simple operation of switch 13, eliminating the need for complex equipment reconfiguration and wiring rewiring, thus significantly reducing test time. For example, in mass production, an efficient testing process can significantly increase the number of products tested per unit time, thereby reducing production costs.

[0056] It should be noted that the control circuit board of this application is pre-set with test circuits for different products, and the through-hole control switch 13 can realize the switching of different test circuits. However, the specific circuit structure is not within the scope of protection of this application, so its structure will not be described in detail.

[0057] Example 2

[0058] This embodiment is an improvement on embodiment 1.

[0059] like Figures 1-5 As shown, in this embodiment, the test body 1 is also provided with a first connection port 14 and a second connection port 15, both of which are electrically connected to the control circuit board.

[0060] The first connection port 14 and the second connection port 15 provide test interfaces for the semi-finished speaker. During use, the alligator clip end of the semi-finished speaker's cable is connected to the two connection ports, and the test mode is switched by toggling the toggle switch 13, thus enabling the testing of the semi-finished speaker. This usage method provides more application scenarios for this multi-functional automatic testing device.

[0061] In this embodiment, a main control switch 16 is provided on the top of the test body 1, and the main control switch 16 is used to control the circuit on and off of the test body 1.

[0062] Example 3

[0063] This embodiment is an improvement on embodiment 1.

[0064] like Figures 1-5 As shown, in this embodiment, the first placement position 31 includes a placement groove 311 and a contour block 312 disposed on the edge of the placement groove 311, wherein the contour block 312 is detachably connected to the placement groove 311.

[0065] The edge of the contour block 312 and the placement groove 311 form the first placement position 31.

[0066] In this embodiment, the bottom of the placement groove 311 is provided with a mounting hole, and the contour block 312 is detachably connected to the mounting hole via a connector 313.

[0067] The combination of the detachable contour block 312 and the placement slot 311 allows for flexible adjustment to products of different shapes and sizes. For various voice module components or other similar components, regardless of their shape, precise adaptation can be achieved by replacing the appropriate contour block 312. This precise adaptation ensures the stability of the product in its placement position, reducing testing errors caused by product shaking or displacement during testing, thereby improving the accuracy of test results. For example, when testing small and irregularly shaped voice modules, the specially customized contour block 312 can tightly wrap around the product, allowing the probe 41 to accurately contact the test point, effectively avoiding erroneous test results due to poor contact.

[0068] Because the contour block 312 can closely match the shape of the product, operators can more easily and quickly place the product in the correct position, improving the convenience and efficiency of the testing operation. At the same time, it also reduces the risk of damage to the product due to improper placement.

[0069] In addition, the presence of the contour block 312 also serves as a foolproof mechanism, preventing the product under test from being misplaced.

[0070] Example 4

[0071] This embodiment is an improvement on embodiment 1.

[0072] like Figures 1-5 As shown, in this embodiment, the lifting drive structure 5 includes a wrench 52 and a lifting rod 51. The test bracket 2 is provided with a guide sleeve 55, and the lifting rod 51 passes through the guide sleeve 55 in the vertical direction.

[0073] The test bracket 2 is also provided with a connecting frame 54, and the wrench 52 is hinged to the connecting frame 54. The bottom of the wrench 52 is hinged to the top of the lifting rod 51.

[0074] This embodiment employs a lifting drive structure 5 composed of a wrench 52 and a lifting rod 51. Its operation is simple and intuitive, requiring no complex electrical control or hydraulic equipment. Operators only need to manually operate the wrench 52 to raise and lower the test plate 4, reducing the technical requirements and training costs for operators. Compared to some highly automated but structurally complex lifting drive devices, this structure has lower manufacturing costs, reducing investment in testing equipment for enterprises. For example, in small businesses or production environments with strict cost control, this simple lifting drive structure can meet testing needs while effectively reducing equipment procurement and maintenance costs.

[0075] In this embodiment, the test body 1 is provided with a guide rod 53, and the test plate 4 is provided with a guide hole for the guide rod 53 to pass through.

[0076] The design of the guide sleeve 55 and guide rod 53 ensures the stability of the lifting rod 51 and the test plate 4 during the lifting process. The lifting rod 51 moves vertically along the guide sleeve 55, which can prevent deviation or shaking during descent and ensure that the probe 41 at the bottom of the test plate 4 can accurately contact the test point of the product to form a good electrical connection.

[0077] This application also provides a process for using the apparatus to test different components, as detailed below:

[0078] (1) When testing the voice module:

[0079] Place the voice module in the product placement position on the tray, and press down the test plate to clamp and secure the voice module. Simultaneously, connect the probes to the test points on the voice module to ensure effective power-on operation.

[0080] Connect the voice module connector to the speaker and microphone. Turn on the main control switch to power on the control circuit board, ensuring the voice module, speaker, and microphone are powered on.

[0081] Once the mobile terminal and voice module are connected to the network, the voice module can be given functions such as adjusting temperature, setting mode, and playing music, news, and entertainment.

[0082] After the test is completed, turn off the power, remove the voice module, microphone, and speaker, and proceed with the next batch of tests.

[0083] (2) When testing the patch microphone:

[0084] Place the patch microphone in the product placement position, make the probes of the test board contact the positive and negative terminals of the patch microphone, and use the test board to press the patch microphone firmly.

[0085] Toggle the switch to select the speaker that comes with the testing device and install the matching voice module. Turn on the main control switch to power on the control circuit board, and the matching voice module and the speaker that comes with the testing device will be powered on and running.

[0086] Then, the mobile terminal was connected to the Internet. After the connection was successful, the accompanying voice module was tested to provide functions such as adjusting temperature, mode, playing music, news and entertainment.

[0087] (3) When testing semi-finished loudspeakers:

[0088] When using the alligator clip end of the semi-finished speaker cable, correctly connect the first and second connection ports, and at this time you need to distinguish between the positive and negative terminals.

[0089] Flip the switch to adjust the microphone to the microphone that comes with the testing device and assemble the matching voice module.

[0090] Turn on the main control switch to power on the control circuit board, which in turn powers on the connected speaker, enabling the accompanying voice module and microphone to operate.

[0091] Then, the mobile terminal was connected to the Internet. After the connection was successful, the accompanying voice module was tested to provide functions such as adjusting temperature, mode, playing music, news and entertainment.
