Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to a marking structure of microphone FPC automatic testing equipment. 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 test and FCT test. The marking module 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 is conducted manually with the help of the test instrument. The microphone is manually placed on the test instrument. After the marking module 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 test 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 test 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
