[0020] When audio products such as speakers are undergoing automated testing, the most important test item is to simulate user operations through a robotic arm and press each button of the product multiple times to detect the reliability and stability of the product. Traditional robotic arms can only fixedly press a single button. However, during the use of most audio products, there are often scenarios where multiple buttons are pressed simultaneously, or after pressing Button A, Button B is continuously pressed. For these test scenarios, traditional robotic arms cannot cover them, that is, they cannot achieve synchronous or asynchronous operations of multiple buttons, resulting in low test efficiency.

[0021] To solve the above problems, please refer to Figures 1 to 5 , the present utility model proposes a robotic arm structure 1000, which includes a single-chip microcomputer 1, a relay module 2, and multiple electromagnet structures 3. The relay module 2 includes multiple relays, and each relay is electrically connected to the single-chip microcomputer 1; the electromagnet structures 3 are arranged at intervals, one relay is electrically connected to one electromagnet structure 3, and each electromagnet structure 3 includes an electromagnet 31 and a pressing member 32. When the electromagnet 31 is energized, it drives the pressing member 32 to move up and down to press the button; the pressing member 32 includes a pressing block 321 and an elastic metal pressing member 322, and the pressing block 321 and the elastic metal pressing member 322 can be interchangeably arranged on the electromagnet 31.

[0022] The technical solution of the present utility model controls the energization and de-energization of each relay in the relay module 2 by using the single-chip microcomputer 1, thereby controlling the pressing and lifting of the pressing member 32 at the bottom of each electromagnet structure 3, achieving the effect of synchronous or asynchronous pressing of multiple buttons by the pressing member 32, achieving the purpose of pressing test on the buttons, enabling the test robotic arm to achieve diversified tests, meeting the requirements for various tests. In addition, by setting the interchangeable pressing block 321 and elastic metal pressing member 322, it can meet the detection of various mechanical buttons and touch buttons by the electromagnet structure 3, improving the test efficiency and applicability of the test robotic arm.

[0023] In an alternative embodiment, to detect the pressing of buttons with a relatively small spacing on the audio device, the robotic arm structure 1000 further includes a mounting base 4 and a cross bar 5. The cross bar 5 includes a first cross bar 51 and a second cross bar 52 disposed above the first cross bar 51. Mounting bases 4 are provided on both the first cross bar 51 and the second cross bar 52. An electromagnet structure 3 is disposed on one mounting base 4, and the pressing member 32 of the electromagnet structure 3 on the second cross bar 52 is disposed between two adjacent electromagnet structures 3 on the first cross bar 51. Please refer to Figure 1 , by arranging the first cross bar 51 and the second cross bar 52 at intervals in the vertical direction, and providing mounting bases 4 on the first cross bar 51 and the second cross bar 52 for mounting the electromagnet structures 3, and arranging the electromagnet structures 3 at intervals between the first cross bar 51 and the second cross bar 52, so that the pressing member 32 of the electromagnet structure 3 on the second cross bar 52 is located between the gaps of two adjacent electromagnet structures 3 on the first cross bar 51. In this way, the arrangement of the pressing members 32 is made closer in the horizontal direction to meet the pressing detection of buttons with a smaller spacing, and the practicability of the robotic arm structure 1000 is improved.

[0024] Furthermore, to facilitate the adjustment of the spacing between the pressing members 32, the mounting base 4 is slidably connected to the cross bar 5, and the mounting base 4 can slide along the extension direction of the first cross bar 51 / second cross bar 52. By movably arranging the mounting base 4 on the first cross bar 51 or the second cross bar 52, the spacing between the electromagnet structures 3 can be changed by adjusting the relative position of the mounting base 4 on the first cross bar 51 and the second cross bar 52, so as to adjust the distance between the pressing members 32 to adapt to the pressing detection of buttons with various spacings and improve the adaptability of the robotic arm structure 1000.

[0025] In an alternative embodiment, to realize the installation and replacement of the pressing member 32, the pressing member 32 is screwed to the output end at the bottom of the electromagnet 31. In the actual design process, a threaded hole can be provided at the output end of the electromagnet 31, and an external thread can be provided at one end of the pressing member 32 close to the electromagnet 31. By screwing the pressing member 32 into the threaded hole, the pressing member 32 can be installed at the output end of the electromagnet 31 to facilitate driving the pressing member 32 to lift for pressing detection. This not only facilitates the installation and disassembly of the pressing member 32, but also facilitates the replacement of different types of pressing members 32 to adapt to the detection requirements of different types of buttons. In other embodiments, connection holes can also be provided on both the output end of the electromagnet 31 and the pressing member 32, and the two can be connected and fixed by screwing a screw or a bolt through the two connection holes. Specifically, it can be selected according to actual needs and will not be specifically limited here.

[0026] In an optional embodiment, to facilitate the arrangement of the pressing member 32 between two adjacent electromagnet structures 3, the electromagnet structure 3 further includes a connecting rod 33. The two ends of the connecting rod 33 in the extending direction are respectively connected to the output end of the electromagnet 31 and the pressing member 32. Please refer to Figure 1 , by arranging the connecting rod 33 between the output end at the bottom of the electromagnet 31 and the pressing member 32, the height of the electromagnet structure 3 is extended through the connecting rod 33, so that the pressing members 32 on the electromagnet structures 3 mounted on the second cross bar 52 and the pressing members 32 on the electromagnet structures 3 on the first cross bar 51 can be kept on the same horizontal plane to detect the keys on the audio device. In this way, by arranging the connecting rod 33, it is also convenient to arrange the pressing member 32 between two electromagnet structures 3 on the first cross bar 51, so as to minimize the horizontal distance between two adjacent pressing members 32 as much as possible, thereby adapting to the detection of keys with a small distance. The connecting rod 33 can also be connected to the output end of the electromagnet 31 by screwing. In addition, to facilitate the assembly of the robotic arm structure 1000, the connecting rod 33 and the pressing member 32 are detachably connected. In the actual design process, the connecting rod 33 and the pressing member 32 can be an integral structure or a split design. When the connecting rod 33 and the pressing member 32 are an integral structure, to make the pressing ends at the bottom of the pressing member 32 keep on the same horizontal plane, it is only necessary to install pressing members 32 with different lengths on the first cross bar 51 and the second cross bar 52; when the connecting rod 33 and the pressing member 32 are a split design, the pressing member 32 is screwed to the end of the connecting rod 33 away from the electromagnet 31 to realize the detachable connection between the connecting rod 33 and the pressing member 32. In this way, when installing the robotic arm structure 1000, it is only necessary to determine whether a connecting rod 33 needs to be arranged between the electromagnet 31 and the pressing member 32 to extend the length of the electromagnet structure 3 according to whether the electromagnet structure 3 is installed on the first cross bar 51 or the second cross bar 52, which improves the installation efficiency of the robotic arm structure 1000 and also improves the installation adaptability of the connecting rod 33 and the pressing member 32, and can be assembled and used corresponding to each use scenario. Optionally, in this embodiment, the connecting rod 33 is a hexagonal stud, so as to facilitate the installation and disassembly of the connecting rod 33 with tools such as a wrench. In other embodiments, the connecting rod 33 can also be a triangular stud, a square stud or other columnar structures with edges, so as to facilitate the application of force when clamping the connecting rod 33 for screwing and improve the convenience of disassembly and assembly. The specific shape can be selected according to actual needs and is not specifically limited here.

[0027] In an alternative embodiment, to facilitate the robotic arm structure 1000 to detect various types of buttons, the pressing block 321 is a nut, and the elastic metal pressing member 322 is a spring. In common audio products, the buttons include mechanical buttons and touch buttons. When detecting mechanical buttons, the nut is used as the pressing member 32 to press and detect the buttons. When it is necessary to detect touch buttons, the pressing member 32 at the output end of the electromagnet 31 is replaced with a spring for pressing detection. Since the spring has a certain elasticity, it can buffer a part of the downward pressure at the output end of the electromagnet 31, and can provide a certain protection for the touch buttons. In addition, it should be noted that the pressing end of the spring in contact with the touch button is provided with a flat pressing end face, which can be achieved by connecting a sheet-like structure to one end of the spring. That is to say, the spring and the touch button are in surface contact, which increases the contact area between the spring and the touch button, so that the spring can better trigger the touch button to complete the detection. In this way, the mechanical buttons and touch buttons are detected by the nut and the spring respectively to meet the detection requirements of various types of buttons and improve the applicability of the robotic arm structure.

[0028] In an alternative embodiment, to provide temperature control protection for the robotic arm structure 1000, the robotic arm structure 1000 further includes a temperature control switch 6. A temperature control switch 6 is provided on the side wall of an electromagnet 31, and the temperature control switch 6 is electrically connected to the electromagnet 31. Please refer to Figure 1 , a temperature control switch 6 is provided on the side wall of each electromagnet 31. When it is detected that the temperature of the electromagnet 31 reaches a certain critical value, the power supply circuit of the electromagnet structure 3 is disconnected through the temperature control switch 6, so that the electromagnet structure 3 stops operating and cools down, avoiding potential safety hazards caused by overheating due to continuous operation of the electromagnet structure 3, and improving the safety and reliability of the robotic arm structure 1000.

[0029] In an alternative embodiment, to facilitate the pressing detection of the buttons of the audio product, the maximum pushing and pulling force of the electromagnet 31 is F, 30N ≤ F ≤ 50N, and the width of the electromagnet 31 is A, 1.5 cm ≤ A ≤ 2.5 cm. While ensuring that the electromagnet structure 3 has sufficient pressing force to complete the pressing detection, it is also necessary to avoid damaging the buttons due to excessive pressing force. In this embodiment, an electromagnet 31 with a maximum pushing and pulling force of 40N and a width of 2 cm is used, which not only ensures the reliability of the pressing detection, but also enables the electromagnet 31 structure to be arranged more compactly to adapt to the detection of buttons with a smaller pitch. The axial pitch of each pressing member 32 below the electromagnet structure 3 in this embodiment can be as small as 1.2 cm at minimum. The electromagnet structure 3 in this embodiment is only a preferred solution, and can be specifically selected according to actual usage requirements, and no specific limitation is made here.

[0030] The present utility model further provides an automatic detection device, which includes a robotic arm structure 1000. The specific structure of the robotic arm structure 1000 refers to the above embodiments. Since this automatic detection device adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated herein one by one.

[0031] The above is only an exemplary embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present utility model.
