[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 the FCT test instrument for a sound leakage test. When taping or moving the microphone FPC to the FCT tester, the risk of damage to the microphone FPC increases. In addition, the taping efficiency is low, and there is a risk of missing or wrong taping, which reduces the yield of the microphone FPC product.

[0004] In view of this, the present invention is aimed at the many shortcomings and inconveniences caused by the imperfection of the existing microphone FPC gluing method, and is developed through active research, improvement and trial production. Utility Model Content

[0019] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0020] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0021] like Figure 1 and Figure 2 As shown, the utility model discloses an FPC automatic gluing device, which includes a gluing bracket 41, a tape fixing roller 42, a guide roller 43, a glue stripping positioning mechanism 44, a tape recovery mechanism 45, a movable module 46 and a visual module 47. The tape fixing roller 42 is arranged on the gluing bracket 41, the guide roller 43 is arranged at intervals on the gluing bracket 41 on one side of the tape fixing roller 42, the glue stripping positioning mechanism 44 is arranged between the guide roller 43 and the tape recovery mechanism 45, the movable module 46 is arranged on one side of the gluing bracket 41, and can be moved between the tape recovery mechanism 45 and the gluing station, the movable module 46 is equipped with a patch suction nozzle 461 for sucking the tape segment, and the visual module 47 is arranged between the glue stripping positioning mechanism 44 and the gluing station. Before the present invention is used, the adhesive tape formed by the release paper and the cut tape segments pasted on the release paper is stored into an adhesive tape roll, which is fixed on the adhesive tape fixing roller 42. After the front end of the adhesive tape roll passes around the guide roller 43, it passes through the top of the adhesive stripping positioning mechanism 44, and then is rolled down from the front end of the adhesive stripping positioning mechanism 44 to the adhesive paper recycling mechanism 45. The adhesive tape refers to the release film and the adhesive tape segments bonded together, and the adhesive tape roll refers to the rolled adhesive tape.

[0022] Among them, the adhesive paper recovery mechanism 45 is connected to the driving mechanism, and the driving mechanism can drive the adhesive paper recovery mechanism 45 to rotate so as to reel up the release film from which the tape segment has been peeled off. During reeling, the adhesive tape fixing roller 42 can be driven to rotate at the same time to convey the tape roll forward, thereby realizing the recovery of the adhesive paper and the automatic conveyance of the tape roll.

[0023] 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.

[0024] 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, stoppers 443 are arranged on both sides of the tape fixing platform 441 and the suction ports 442. The distance 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.

[0025] 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 patch nozzle 461 is installed on the Z-axis linear module 464, and the Z-axis linear module 464 can drive the patch nozzle 461 to move forward, backward, left, right, up and down.

[0026] The visual module 47 is arranged in front of the stripping positioning mechanism 44, and has a module bracket 471, a camera 472 and a light source 473. 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.

[0027] Before the microphone FPC performs sound leakage detection, it will first be transmitted to the front of the FPC automatic gluing equipment of the present invention, and the patch suction nozzle 461 of the mobile module 46 will move 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 will peel off the tape segment on the release paper from the glue stripping positioning mechanism 44 and move to the top of the visual module 47. The visual module 47 will detect whether the patch suction nozzle 461 has sucked the tape segment. At the same time, the tape recovery mechanism 45 will drive the tape roll to roll and recover the tape roll by a distance of a tape segment, so that the glue stripping positioning mechanism 44 will be covered with a new tape segment again. 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.

[0028] The utility model FPC automatic gluing equipment realizes automatic conveying of the tape and automatic recycling of the release film through the tape fixing roller 42 and the adhesive paper recycling mechanism 45, determines the conveying 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.

[0029] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
