The SEAL head 312 cooperates with the SEAL tape to seal around the MIC flexible circuit board of the product being tested, and the head lifting cylinder 315 is responsible for driving the SEAL head 312 to lift.

[0050] The SEAL tape includes a tape winding disc 3132 and a SEAL film 3131, and the tape winding structure includes a tape winding driver 3141 and a tape winding disc 3142. The SEAL film 3131 passes over the top of the SEAL head 312 and is wound on the tape winding disc 3142. The tape winding driver 3141 is preferably a stepper motor, which has high precision, long service life, and good control, and is used to provide driving force to drive the tape winding disc 3142 to wind the SEAL tape.

[0051] Meanwhile, the MIC sealing assembly 31 in the embodiment is also provided with a first pressure sensor 316 and a photoelectric sensor 317 for detecting the working state of the SEAL tape.

When the product is positioned by the manual operation into the needle mold assembly 37 of the carrier plate mechanism 3, the top plate mechanism 2 is pressed down to the carrier plate mechanism 3 and reaches the hard limit position, the pressure MIC assembly 22 starts to work, the pressure head 221 is pressed down to the product MIC, the MIC hole of the product under test is concentrically attached to the sound hole of the sound source box 241, the sound source box 241 emits sound from the bottom sound source tube to the MIC hole, and the sensitivity test of the product is performed. After the test is completed, the top plate is lifted, the product is manually taken and placed into the tray, and the next step is repeated. The pressure MIC assembly 22 is compatible with the test, and the entire functional requirement is met, and the original film tearing process is cancelled.

[0063] In the sound leakage and open short circuit test, the MIC sealing assembly 31 is mainly responsible for the sealing work of the product MIC and the recovery of the SEAL tape work, and guarantees the smooth passing of the sound leakage and open short circuit test. The sound leakage test and the open short circuit test are combined into one compatible test in the product test link. When the product under test is positioned by the manual operation into the needle mold assembly 37 of the carrier plate mechanism 3, the top plate mechanism 2 is pressed down to the carrier plate mechanism 3 and reaches the hard limit position, the pressure MIC assembly 22 starts to work, the pressure head 221 is pressed down to the product MIC and the breathable film, the bottom MIC sealing assembly 31 starts to work, the SEAL head 312 is pressed up to seal the SEAL tape, the horn emits sound around the product MIC, and the sound leakage test is performed. The block probe assembly 23 performs the open short circuit test on the important product steel sheet. After the test is completed, the MIC sealing assembly 31 is retracted by the driver, the tape drive 3141 drives the tape reel 3142 to roll away a part of the film tape for recovery, the pressure MIC assembly 22 is lifted after the bottom film tape is completely retracted (to prevent the breathable MIC film from being pulled away by the bottom SEAL tape), and then the product is manually taken and placed into the tray, and the next step is repeated. The SEAL tape is sealed by the head of the MIC sealing assembly 31 in the sealing test and the open short circuit test, and the entire functional requirement is met, and the original film pasting process is cancelled.
