Technical Field

[0001] This utility model relates to the technical field of electronic equipment, and in particular to a detection device. Background Technology

[0002] Currently, electronic devices are equipped with different sound channel holes according to different functional requirements, such as microphone holes and speaker holes. The microphone holes and speaker holes are located on the mid-frame of the phone. During the actual manufacturing process of the mid-frame of the phone, foreign objects such as burrs may appear inside the microphone holes and speaker holes. Burrs can block or clog the microphone holes and speaker holes, thereby affecting the propagation of sound and leading to problems such as unclear hearing and poor sound reception.

[0003] In the existing technology, the detection of burrs in the vocal tract hole usually relies on the operator's visual observation. This method has low detection efficiency and is prone to missed detection, making it difficult to meet the detection requirements. Utility Model Content

The display device 4 is used to acquire and display a magnified image of the ear canal hole of the product to be inspected.

[0031] This application provides a testing device. By incorporating a display device 4, which acquires and displays a magnified image of the sound channel hole of the product to be inspected, the operator can clearly observe the magnified image and quickly determine whether there are burrs inside the sound channel hole. Phone frames with burrs are less likely to be missed, reducing observation and judgment time, thereby improving testing efficiency and lowering the false negative rate. Furthermore, this application also includes a guide rail assembly 2, allowing the inspection fixture 3 to slide along the support frame 1. By moving the inspection fixture 3, different sound channel holes on the product to be inspected, such as microphone holes and speaker holes, can be detected, further improving testing efficiency and reducing the false negative rate.

[0039] Specifically, the axial direction of the guide rail assembly 2 is parallel to the width direction of the base plate 31, so that the product to be inspected moves back and forth along the width direction of the base plate 31, thereby detecting the microphone hole and speaker hole located at the lower end of the product to be inspected.

[0040] In this embodiment, there are two guide rail assemblies 2, which are spaced apart along the length of the base plate 31.

[0041] refer to Figure 1 and Figure 3The display device 4 includes an electron microscope 41 and a display. The electron microscope 41 is disposed opposite to the support frame 1 at a distance.

The bottom end of the first mounting base 61 is fixedly disposed on the top end of the substrate 5. The top end of the first mounting base 61 is rotatably connected to the bottom end of the first clamp 62. The top end of the first clamp 62 is fixedly connected to the second clamp 63. The first clamp 62 and the second clamp 63 clamp the electron microscope 41. The first clamp 62, which rotates relative to the first mounting base 61, can adjust the angle of the electron microscope 41. Adjusting the angle of the electron microscope 41 is beneficial for obtaining a clearer magnified image.

[0046] In this embodiment, the first mounting base 61 and the first clamp 62 are hinged together.

[0047] Specifically, the top end of the first clamp 62 is provided with a first groove 621, and the bottom end of the second clamp 63 is provided with a second groove 631.

[0051] Specifically, the light-transmitting hole 7 and the electron microscope 41 are arranged opposite to each other. The light emitted by the light source shines on the sound channel hole of the product under inspection through the light-transmitting hole 7. By illuminating the sound channel hole of the product under inspection through the light source, the electron microscope 41 can obtain an image with sufficient brightness, thereby making the magnified image clearer and further facilitating the operator to observe the inside of the sound channel hole.

[0052] The operation process of the testing device in this application is as follows: First, adjust the position of the light source to ensure that the light is aligned with the sound channel hole. Connect the monitor and adjust the distance and width of the light. After the above adjustments are made, the operator places the product to be inspected on the inspection fixture 3, and can then clearly see the structure and burrs inside the sound channel hole. Therefore, the operator can use the testing device of this application to magnify the burrs inside the sound channel hole, thereby accurately removing the burrs inside the sound channel hole.
