Description

TECHNICAL FIELD

[0002] In order to improve the quality of conversation, the special earphone in the field such as game or telephone customer service will set up the conversation microphone stick on the earphone main part. Figure 1 And Figure 2 The conversation microphone stick 100 includes the microphone stick head 100a for connecting with the earphone main part, the microphone stick body 100b with one end fixedly connected with the microphone stick head 100a and the microphone 100c connected to the other end of the microphone stick body 100b;

[0003] The microphone stick head 100a is equipped with the limiting pivot 100d for rotatingly connecting with the earphone main part and the magnet mounting groove 100a2 for installing the microphone magnet 100e.When the conversation microphone stick 100 rotates to the preset angle relative to the earphone main part, the microphone magnet 100e is aligned with the positioning magnet on the earphone main part and is magnetically positioned, so that the conversation microphone stick 100 can be guaranteed to be at the fixed angle, and the situation that the conversation microphone stick 100 is randomly rotated to affect the quality of conversation is avoided.

[0004] Generally, the microphone magnet 100e is fixedly connected with the groove bottom of the magnet mounting groove 100a2 through the viscose layer:

[0005] If the thickness of the viscose layer is too large, the surface (hereinafter referred to as "magnetic attraction surface") of the microphone magnet 100e away from the groove bottom of the magnet mounting groove 100a2 will protrude outward, and when the conversation microphone stick 100 is subsequently installed on the earphone main part, the magnetic attraction surface is easy to rub with the earphone main part, affecting the smoothness when the conversation microphone stick 100 rotates.

[0006] If the thickness of the viscose layer is too small, the viscose force is insufficient, and the microphone magnet 100e is easy to fall off.

[0007] At present, there is no suitable equipment to detect the thickness of the viscose layer, and workers can only rely on past experience to judge whether the thickness of the viscose layer is appropriate, which has low accuracy and is easy to cause assembly failure in subsequent assembly.

[0060] Workbench 1;

[0061] Magnetic push type microphone fixing assembly 2, the magnetic push type microphone fixing assembly 2 is installed on the workbench 1, for pushing and fixing the microphone head 100a;

[0062] A distance measuring sensor 3 is installed on the working platform 1 and located at the side of the magnetic push type microphone fixed assembly 2, and is used to obtain the measured horizontal distance from the microphone magnet 100e to the distance measuring sensor 3;

[0063] A control device is electrically connected with the distance measuring sensor 3, used to receive the measured horizontal distance, and compare the measured horizontal distance with a preset distance range, so as to determine whether the adhesive layer thickness is within the allowable thickness range.

[0064] The working process of the microphone adhesive thickness detection equipment provided by the embodiment is as follows:

[0065] S10: placing a call microphone 100:

[0066] The call microphone 100 to be detected is placed on the magnetic push type microphone fixed assembly 2 of the equipment, and the magnetic push type microphone fixed assembly 2 fixes the microphone head 100a at a predetermined position through the magnetic repulsion force, so as to ensure that the call microphone 100 does not move during the detection process;

[0067] S20: starting the distance measuring sensor 3 to obtain the measured horizontal distance:

[0068] The distance measuring sensor 3 is started, the sensor sends a distance measuring signal, and points to the magnetic attraction surface of the microphone magnet 100e;

[0069] The distance measuring sensor 3 receives the signal reflected from the microphone magnet 100e, and calculates the measured horizontal distance from the microphone magnet 100e to the distance measuring sensor 3.

[0070] S30: data transmission and processing:

[0071] The measured horizontal distance data is transmitted to the control device through electrical connection, the control device compares the measured horizontal distance with the preset allowable thickness range, and judges whether the adhesive layer thickness is within the allowable range according to the comparison result:

[0072] It should be noted that the thickness of the adhesive layer directly affects the distance between the magnetic attraction surface of the microphone magnet 100e and the distance measuring sensor 3. If the thickness of the adhesive layer is too large, the magnetic attraction surface will protrude outward, resulting in a decrease in the measured horizontal distance; if the thickness of the adhesive layer is too small, the magnetic attraction surface will be close to the groove bottom, resulting in an increase in the measured horizontal distance.

[0075] In the embodiment, the magnetic push type microring fixing assembly 2 comprises a fixed limiting plate 201 fixed on the working platform 1, a sliding push plate 202 located on one side of the fixed limiting plate 201 close to the distance measuring sensor 3 and in sliding connection with the working platform 1, and a magnetic push assembly 203 driving the sliding push plate 202 to slide away from the fixed limiting plate 201.

[0076] The magnetic push assembly 203 comprises a fixed magnet 2031 installed on one side of the fixed limiting plate 201 close to the sliding push plate 202, and a sliding magnet 2032 installed on one side of the sliding push plate 202 close to the fixed limiting plate 201. Further, the magnetic poles of the fixed magnet 2031 and the sliding magnet 2032 are opposite.

[0082] S102: Load microring head 100a:

[0083] The repulsive force of the magnetic pushing assembly 203 overcomes the pushing of the sliding push plate 202 to the position close to the fixed limiting plate 201, and the distance between the sliding push plate 202 and the fixed limiting plate 201 is less than the distance between the first thrust surface 100a1 and the second thrust surface 100d1; at this time, the microphone head 100a can be placed on the sliding push plate 202 and the fixed limiting plate 201, and after the sliding push plate 202 is loosened, the repulsive force of the sliding magnet 2032 and the fixed magnet 2031 makes the sliding push plate 202 slide away from the fixed limiting plate 201, and then the fixed limiting plate 201 abuts against the first thrust surface 100a1 and the sliding push plate 202 abuts against the second thrust surface 100d1, thereby realizing reliable positioning of the call microphone 100.

[0084] In the embodiment, the bottom of the working platform 1 is hingedly connected with a receiving box 4, and the working platform 1 is used to cover the upper end opening of the receiving box 4.

[0086] The operating personnel can put the call microphone 100 that passes the detection into the good product storage bin through the good product discharging opening 101 and put the call microphone 100 that fails the detection into the defective product storage bin through the defective product discharging opening 102. Finally, the working platform 1 is turned to open, and the call microphone 100 can be taken out through the upper end opening of the receiving box 4.
