Description

Technical Field

[0002] A microphone is a transducer that converts sound into an electronic signal. It is commonly found in electronic devices such as microphones, recorders, mobile phones, and cameras. Microphone modules are usually installed in electronic devices with voice functions. After the microphone module is manufactured, the microphone needs to be tested to ensure that the product is normal. The test generally includes ICT testing and FCT testing. The ICT test instrument is used to detect whether the connection of the microphone FPC is qualified. The FCT test includes a sound leakage test, that is, to test whether the microphone hole leaks sound. The microphone hole needs to be glued during the test.

[0003] Before detecting whether the existing microphone is leaking sound, it is necessary to manually tape the microphone hole and then manually place it on a sound leakage tester for a sound leakage test. When tape is taped or the microphone FPC is moved to the sound leakage tester, the risk of damage to the microphone FPC increases. In addition, the tape taping efficiency is low, and there is a risk of missing or wrong taping, which reduces the yield of the microphone FPC product.

After the front end of the tape roll bypasses the guide roller 43, it passes through the top of the glue stripping positioning mechanism 44, and then is rolled down from the front end of the glue stripping positioning mechanism 44 on the adhesive paper recycling mechanism 45. The adhesive tape refers to the release film and the adhesive tape segment bonded together, and the adhesive tape roll refers to the adhesive tape in a roll; the sound leakage test mechanism 5 is arranged on the chassis 1 and is located on one side of the sound leakage test station 22, and the sound leakage test mechanism 5 includes a sound leakage test bracket 51, a lifting module 52 and a sound leakage tester 53, the sound leakage test bracket 51 is fixedly arranged on the chassis 1, the lifting module 52 is fixedly arranged on the sound leakage test bracket 51, and the sound leakage tester 53 is fixedly arranged on the lifting module 52, so that the lifting module 52 can carry The dynamic sound leakage tester 53 moves up and down.

After the test is completed, the lifting module 52 drives the sound leakage tester 53 to rise and reset.

[0028] The glue sticking station 21 and the sound leakage detection station of the turntable 2 have a fixing seat 27 for placing a test tool (not shown in the figure).

During reeling, the adhesive tape fixing roller 42 can be driven to rotate at the same time to convey the adhesive tape roll forward, thereby realizing the adhesive paper recovery and the automatic conveyance of the adhesive tape roll.

[0032] The glue sticking bracket 41 of the utility model is fixedly set on one side of the chassis of the microphone FPC automatic testing equipment, the tape fixing roller 42 is set on the upper part of the rear end position of the glue sticking bracket 41, and a plurality of guide rollers 43 are provided, which are respectively arranged above, in front of and below the tape fixing roller 42, wherein the guide roller 43 located below is slightly higher than the height of the glue stripping positioning mechanism 44, and a driven roller can be preferably set on each guide roller 43, which can follow the rotation during the tape transmission process, thereby reducing the friction during the tape transmission process and saving more effort.

[0033] The stripping and positioning mechanism 44 comprises a tape fixing platform 441, and a wind cavity for installing a fan (not shown in the figure) is arranged below the tape fixing platform. The tape fixing platform 441 is provided with a plurality of suction ports 442 connected to the wind cavity at the position corresponding to the wind cavity. In order to make the tape as much as possible on the suction ports 442, the tape fixing platform 441 is provided with stoppers 443 on both sides of the suction ports 442. The spacing between the two stoppers 443 is greater than or equal to the width of the tape, and the tape is located between the two stoppers 443. When stripping the tape, the fan is started, and the tape located above the tape fixing platform 441 is sucked onto the release film through the suction ports 442, so that the patch suction nozzle 461 of the mobile module 46 can easily peel off the tape segment from the tape.

[0034] The movable module 46 includes the patch nozzle 461, the X-axis linear module 462, the Y-axis linear module 463 and the Z-axis linear module 464. The X-axis linear module 462 is fixedly arranged on the adhesive mounting bracket 41 and is located on one side of the tape fixing roller 42. The Y-axis linear module 463 can be slidably arranged on the X-axis linear module 462 forward and backward. The Z-axis linear module 464 can be slidably arranged on the Y-axis linear module 463 left and right.

The camera 472 and the light source 473 are fixedly arranged on the module bracket 471. The camera head of the camera 472 and the light source 473 are both arranged upward. The camera is pointed upward to shoot whether the patch suction nozzle 461 absorbs the tape segment. The light source can assist in improving the shooting light of the camera 472 according to actual conditions.

[0036] Before the microphone FPC performs sound leakage detection, it will first be transmitted to the front of the automatic gluing mechanism of the microphone FPC of the utility model, and the patch suction nozzle 461 of the mobile module 46 moves to the top of the glue stripping positioning mechanism 44. After the glue stripping positioning mechanism 44 sucks the tape, the patch suction nozzle 461 of the mobile module 46 peels off the tape segment on the release paper from the glue stripping positioning mechanism 44 and moves to the top of the visual module 47. The visual module 47 detects whether the patch suction nozzle 461 has sucked the tape segment. At the same time, the tape recovery mechanism 45 drives the tape roll to roll and recovers the tape roll by a distance of a tape segment, so that the glue stripping positioning mechanism 44 is re-covered with a new tape segment. If the visual module 47 detects the tape, the moving module 46 drives the patch suction nozzle 461 to move to the top of the glue sticking position of the glue sticking station and presses down to stick the tape segment to the microphone hole position of the microphone FPC. If the tape segment is not detected, the moving module 46 drives the patch suction nozzle 461 to move to the glue stripping positioning mechanism 44 to re-absorb the tape segment.

[0037] The microphone FPC automatic gluing mechanism of the present invention realizes automatic transmission of the tape and automatic recovery of the release film through the tape fixing roller 42 and the adhesive paper recycling mechanism 45, determines the transmission direction of the tape through the guide roller 43, fixes the tape through the glue stripping positioning mechanism 44, and then drives the patch suction nozzle 461 through the moving module 46 to realize the stripping of the tape segment and stick the tape segment on the microphone hole of the microphone FPC, and then cooperates with the visual module 47 for monitoring to ensure that the tape segment is stripped from the tape. The entire gluing process does not require human participation, the gluing efficiency is high, and there is no need to manually touch the microphone FPC, which can avoid human damage and improve the yield of the microphone FPC; the turntable 2 is rotated to realize automatic entry from the gluing station 21 to the leakage test station 22, and then the leakage test of the microphone FPC is realized through the leakage test mechanism.
