Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to an automatic detection device for a microphone. Background Art

[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] The existing microphone ICT test uses manual cooperation with the test instrument to test. The microphone is manually placed on the test instrument. After the ICT test instrument tests the microphone FPC, qualified products are transferred to the FCT test process for FCT testing. Before the sound leakage test, the microphone hole is manually glued and then manually placed on the FCT test instrument for sound leakage testing. After the FCT test, the material is unloaded and placed on the plate manually. The microphone testing process requires the cooperation of multiple people, including ICT testing, gluing testing, sound leakage testing and unloading and placing on the plate. This traditional testing method has unstable personnel, wastes manpower, and increases labor costs. In addition, manual testing is prone to missed tests, misdetection, and misaligned glue that affects the sound leakage test. Manual placement increases the risk of damage to microphone products, low testing efficiency, and reduced product yield.

[0004] In view of this, the present invention is designed to address the many deficiencies and inconveniences caused by the imperfections of existing microphone testing methods, and actively researches, improves and tests to develop the present invention. Utility Model Content

[0058] S9. After the sound leakage and FCT tests are completed, the test tooling is powered off, and the turntable 2 drives the test tooling to rotate to the marking station. At the same time, the test tooling at the gluing station 24 rotates to the second inspection station 25, the test tooling at the first inspection station 23 rotates to the gluing station 24, and the test tooling at the loading station 21 rotates to the first inspection station 23.

[0059] S10, unloading is performed according to the test results. If the microphone circuit board rotated to the unloading station 26 is a good product, the automatic unloading and panning mechanism 6 obtains the microphone circuit board from the unloading station 26 and places it in the unloading pan 63 for panning. If it is a defective product, wait for the microphone circuit board located at the second inspection station 25 to perform the inspection action of step S8, the microphone circuit board located at the gluing station 24 to perform the gluing action of step S6, and the microphone circuit board located at the first inspection station 23 to perform the functional test of step S4. After the test tooling located at the loading station 21 performs the loading action, the defective product is rotated to the loading station 21 for manual unloading.

[0060] In this embodiment, the process of the automatic unloading and plate-swinging mechanism 6 is as follows: the third lifting module 644 of the flipping mechanism 64 of the automatic unloading and plate-swinging mechanism 6 drives the flipping plate 641 and the flipping module 642 to descend, and after the unloading suction nozzle 643 sucks the microphone circuit board on the unloading station 26, the third lifting module 644 drives the flipping plate 641 and the flipping module 642 to rise and reset, and then the flipping module 642 drives the flipping plate 641 to flip 180 degrees, so that the side that sucks the microphone circuit board is turned upwards, and after the plate-swinging robot 62 moves to the top of the flipping plate 641, it sucks the microphone circuit board and places it in the unloading tray 63 for plate-swinging.

[0061] This completes a complete detection of the microphone circuit board.

[0062] The utility model integrates microphone circuit board bending, functional testing (ICT), gluing, sound leakage, FCT detection and automatic unloading and placing in the same set of equipment. The operation requirements are met by the rotation of the turntable 2. The entire test process does not require manual participation, reducing the risk of defective products caused by human operating errors. The use of automatic testing can greatly improve test efficiency, improve automated operations, optimize production efficiency, and improve product quality.

[0063] 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.
