Description

Technical Field

[0001] The utility model relates to the technical field of microphone wiring component detection, in particular to an automatic detection device for microphone wiring components. Background Art

[0002] Mobile phones, tablets, electronic watches, and other electronic products all use microphone cables. The microphone holes are typically protected by a dust-proof film. During production, the microphone holes must always face downward to prevent dust and foreign matter from entering the microphone cavity and causing malfunction. Therefore, microphones must be inspected during production to rule out problems such as damaged dust-proof films and dust accumulation to ensure proper microphone function.

[0003] Due to the extremely small size of the dustproof protective film, dust, scratches, and other defects on its surface are difficult to detect with the naked eye, typically requiring manual inspection using a 100x magnification instrument. The flexible nature of the FPC cable makes it difficult for the microphone cable components to lay flat naturally, further complicating inspection. Furthermore, manual fixing of the microphone is not only time-consuming and labor-intensive, but also carries the risk of damaging the microphone components. This series of issues directly leads to low manual inspection efficiency, difficulty ensuring stable and consistent test results, and the vulnerability of components to damage during operation, ultimately driving up overall production costs.

The drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to facilitate a more thorough and comprehensive understanding of the disclosure of the present invention.

[0034] It should be noted that when an element is referred to as being “fixed to” another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or there may be an intermediate element.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0036] See also Figures 1 to 9 , which is an automatic detection device for microphone cable components according to one embodiment of the present invention, includes an optical detection component 10, a carrier plate 20 installed on the top surface of the optical detection component 10, a loading and unloading component 30 located on one side of the optical detection component 10, and two microphone positioning components 40 installed on the loading and unloading component 30.

[0037] The optical detection assembly 10 includes a detection platform 11, bowl-shaped light sources 12 installed on opposite sides of the bottom surface of the detection platform 11, telecentric lenses 13 connected to the bottom of each bowl-shaped light source 12, an industrial camera 14 coaxially connected to the telecentric lens 13, and a three-axis manual slide 15 that supports and connects to the industrial camera 14; the three-axis manual slide 15 is used to connect to the bottom of the detection platform 11 to facilitate adjustment of the detection position.

[0038] like Figure 5 As shown, the top surface of the test platform 11 is connected to the carrier board 20, which is used to position and place the microphone cable component 50. Specifically, the microphone cable component 50 includes a cable 51 and a microphone 52 attached to one side of the cable 51. The top surface of the test platform 11 is provided with vias 110, which correspond one-to-one with the bowl-shaped light sources 12. This allows light from the bowl-shaped light sources 12 to pass through the vias 110 and illuminate the microphone 52 on the carrier board 20.

[0039] Detection holes 21 are respectively provided on opposite sides of the carrier board 20 . The detection holes 21 penetrate the body of the carrier board 20 . The detection holes 21 correspond to the via holes 110 one by one. The detection holes 21 are used to correspond to the microphones 52 .

[0040] Air tubes 22 are connected to opposite sides of one edge of the carrier board 20. Air tubes 22 are externally connected to a vacuum pump (not shown). Air extraction cavities (not shown) are provided on opposite sides of the carrier board 20, each connected to a corresponding air tube 22. Air extraction holes 23 are provided on opposite sides of the carrier board 20, corresponding to each detection hole 21. These holes 23 connect inwardly to the air extraction cavities. A vacuum pump is used to draw a vacuum, which negatively sucks the cable 51 tightly, preventing the microphone cable 50 from shifting.

[0041] The loading and unloading assembly 30 includes a linear module 31 positioned on one side of the inspection platform 11, a support base 32 connected to the slide of the linear module 31, downward-pressing slide cylinders 33 mounted on opposite sides of the support base 32 near the inspection platform 11, a lifting plate 34 connected to each downward-pressing slide cylinder 33, a support plate 35 mounted at the bottom end of the lifting plate 34, and multiple suction nozzles 36 installed at intervals on the bottom surface of each support plate 35. The suction nozzles 36 are located above the carrier plate 20 and are used to absorb the microphone cable component 50. In actual operation, the linear module 31, downward-pressing slide cylinder 33, and suction nozzles 36 enable the loading and unloading of the microphone cable component 50 on the carrier plate 20.

[0042] The microphone positioning assembly 40 includes a fixed block 41 mounted in the middle of the downward slide cylinder 33, a pressure sensor 42 connected to the fixed block 41, and a pressure rod 43 elastically connected to the bottom end of the pressure sensor 42. The top end of the pressure sensor 42 is connected to the fixed block 41, that is, the pressure sensor 42 is sandwiched between the fixed block 41 and the pressure rod 43. The end of the pressure rod 43 is passed through the support plate 35 and is used to abut the microphone 52 to fix the position of the microphone 52 and prevent the microphone 52 from shifting during the detection process, which may cause detection errors. The presence of the pressure sensor 42 also prevents the pressure rod 43 from excessively squeezing the microphone.

[0043] Specifically, the end of the pressure rod 43 has a silicone pressure head 430 to prevent the pressure rod 43 from making rigid contact with the microphone 52 and causing damage to the surface of the microphone 52 .

[0044] In this embodiment, the top end of the pressure rod 43 is elastically connected to the pressure sensor 42 via a spring 44 .

[0045] The above-mentioned automatic detection device for microphone cable components has a simple structure and is easy to use. The carrier board 20 positions and places the microphone cable component 50, the pressure rod 43 abuts the microphone 52, and the optical detection component 30 is used to detect the microphone 52 upward through the detection hole 21, which greatly improves the detection efficiency and ensures the stability and consistency of the detection results.

[0046] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
