[0049] a working platform 1;

[0050] an elastic clamping assembly 2 mounted on the working platform 1, used for elastically clamping the microphone head 100a so that the axis of the microphone head 100a is in a horizontal state and the microphone rod body 100b extends upward;

[0051] a distance measuring sensor 3 mounted on the working platform 1 and located at the side of the elastic clamping assembly 2, used for obtaining the measured horizontal distance from the microphone rod body 100b to the distance measuring sensor 3;

[0052] a control device electrically connected with the distance measuring sensor 3, used for judging whether the assembly angle deviation between the axis of the microphone rod body 100b and the axis of the microphone head 100a is within the allowed deviation range in combination with the preset allowed distance range and the measured horizontal distance.

[0053] The microphone skew detection device provided by the embodiment has the following working process:

[0054] S10: Clamping the microphone head 100a: First, the microphone head 100a of the microphone 100 is placed in the elastic clamping assembly 2. The elastic clamping assembly 2 automatically clamps the microphone head 100a to ensure that the axis thereof is in a horizontal state, and the microphone rod body 100b extends upward.

[0055] S20: Measuring the distance: The distance measuring sensor 3 is located at the side of the elastic clamping assembly 2 and is used for measuring the horizontal distance from the microphone rod body 100b to the sensor. The distance measuring sensor 3 records the measured horizontal distance.

[0056] S30: Data processing: After receiving the measured data of the distance measuring sensor 3, the control device compares the measured data with the preset allowed distance range. Specifically, the allowed distance range is calculated according to the ideal angle (90°) between the microphone rod body 100b and the microphone head 100a and the allowed deviation range (88° to 92°) and is stored in the control device in advance.

[0057] S40: Judging the deviation: The control device judges whether the angle between the axis of the microphone rod body 100b and the axis of the microphone head 100a is within the allowed deviation range by comparing the measured horizontal distance with the allowed distance range. If the measured horizontal distance is within the allowed distance range, it indicates that the assembly angle deviation meets the requirements; if the measured horizontal distance is outside the allowed distance range, it indicates that the assembly angle deviation is too large and needs to be adjusted or replaced.

[0058] Therefore, the microphone skew detection device can detect the assembly angle deviation before the microphone 100 is assembled to the earphone main body, so that the problem can be found before the late assembly, and the repair cost and time are reduced.

[0059] In the embodiment, the elastic clamping assembly 2 comprises an L-shaped clamping plate 201 fixed to the working platform 1, a vertical clamping plate 202 located on the side of the L-shaped clamping plate 201 away from the distance measuring sensor 3 and in sliding connection with the working platform 1, and an elastic member 203 for driving the vertical clamping plate 202 to slide towards the L-shaped clamping plate 201. The elastic member 203 drives the vertical clamping plate 202 to slide towards the L-shaped clamping plate 201, so that the vertical clamping plate 202 cooperates with the L-shaped clamping plate 201 to clamp and fix the microphone 100.

[0060] Optionally, the elastic member 203 is a spring or an elastic rubber column.

[0061] Further, the L-shaped clamping plate 201 and the vertical clamping plate 202 are magnetically connected.

[0062] Specifically, the L-shaped clamping plate 201 is provided with a fixed magnetic attraction member 204, and the vertical clamping plate 202 is provided with a movable magnetic attraction member 205 corresponding to the position of the fixed magnetic attraction member 204 for magnetically connecting with the fixed magnetic attraction member 204. Further, one of the fixed magnetic attraction member 204 and the movable magnetic attraction member 205 is a magnet, and the other is a magnet or an iron block. After the fixed magnetic attraction member 204 and the movable magnetic attraction member 205 are added, when the elastic pushing force of the elastic member 203 is attenuated due to aging, the vertical clamping plate 202 and the L-shaped clamping plate 201 can still stably clamp the microphone 100.

[0063] Optionally, the distance measuring sensor 3 is a laser sensor, an ultrasonic sensor or an infrared sensor. The above various sensors have their specific application scenarios and advantages and disadvantages, and can be selected according to specific needs.

[0064] In the embodiment, the microphone skew detection device further comprises an indicator light 5, a buzzer 6 and a display screen 4 electrically connected to the control device.

[0065] The control device outputs the judgment result, and usually informs the tester of the detection result through the display screen 4, the indicator light 5 and the buzzer 6. If the detection is qualified, the microphone 100 can continue to be assembled to the earphone main body; if the detection is unqualified, it needs to be reworked or replaced.

[0066] When the assembly angle deviation between the axis of the microphone rod body 100b and the axis of the microphone head 100a is within the allowable deviation range, the indicator light 5 displays green light, and the buzzer 6 emits a short sound to prompt the end of detection.

[0067] When the assembly angle deviation between the axis of the microphone stem 100b and the axis of the microphone head 100a is outside the allowable deviation range, the indicator light 5 flashes red light, and the buzzer 6 long sounds alarm.

[0068] The display screen 4 can display the specific values of the measured horizontal distance and the assembly angle deviation, etc., so that the tester can further understand and handle.

[0069] In summary, the microphone skew detection device provided in the embodiment has the following advantages:

[0070] ①Early detection, reduce repair cost

[0071] The device detects before the microphone 100 is assembled to the earphone body, avoiding the problem of discovering the problem after late assembly, reducing the repair cost and time.

[0072] ②Automatic operation, improve efficiency

[0073] The device automatically clamps the microphone head 100a through the elastic clamping assembly 2, the distance is automatically measured by the distance measuring sensor 3, and the deviation is automatically judged by the control device, reducing the error of human operation and improving the detection efficiency and consistency.

[0074] ③The elastic clamping assembly 2 is reasonably designed and has strong adaptability

[0075] The elastic clamping assembly 2 includes an L-shaped clamping plate 201, a vertical clamping plate 202, and an elastic member 203 (such as a spring or an elastic rubber column), which can stably clamp the microphone head 100a and adapt to different sizes of microphones.

[0076] After adding the fixed magnetic attraction member 204 and the movable magnetic attraction member 205, even if the elastic member 203 is aged and the elastic pushing force is attenuated, the vertical clamping plate 202 and the L-shaped clamping plate 201 can still stably clamp the microphone 100, improving the durability and reliability of the device.

[0077] ④Intuitive result feedback

[0078] The device is equipped with an indicator light 5 and a buzzer 6, which can intuitively feedback the detection result.

[0081] Finally, it should be noted that the above-described embodiments are described in the specification and drawings of the application, but this does not limit the patent protection scope of the application. Any equivalent structure or equivalent process replacement or modification based on the essential concept of the application, using the content described in the specification and drawings of the application, and directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, etc., are all included in the patent protection scope of the application.
