Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to an FPC automatic testing turntable. 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 perform the 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 it is manually placed on the FCT test instrument for sound leakage and FCT 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

[0005] The main purpose of the utility model is to overcome the shortcomings of the prior art and provide an FPC automatic test turntable that can replace manual transplanting of microphone FPCs during the microphone FPC test process, thereby improving test efficiency and improving the yield of microphone FPC products.

[0006] In order to achieve the above purpose, the solution of the utility model is:

[0007] An FPC automatic test turntable is provided with six workstations at equal intervals on the turntable, which are a loading station, a bending station, a first detection station, a gluing station, a second detection station and an unloading station in order. Each workstation of the turntable has a fixing seat for placing a test tool, and the test tool is detachably arranged on the fixing seat. A wiring port that passes through the upper and lower ends of the turntable is provided below the fixing seat corresponding to each workstation of the turntable, and each fixing seat is provided with a wiring hole corresponding to the test tool within the range of the wiring port.

[0008] Furthermore, the top surface of the fixing seat and the bottom surface of the testing fixture are provided with protrusions and grooves that correspond to each other.

[0009] Furthermore, a strong magnet is embedded in the groove, and a metal or magnet that cooperates with the strong magnet is installed on the protrusion.

[0010] Furthermore, the turntable is installed on the top surface of the chassis, and a rotating shaft connected to the motor is provided in the chassis. The bottom end of the rotating shaft is connected to the motor, and the top end of the rotating shaft protrudes to the top surface of the chassis and is fixedly connected to the turntable, so that the turntable rotates above the chassis.

[0011] Furthermore, a turntable mounting hole larger than the outer diameter of the turntable is opened in the middle of the chassis, and the turntable is installed in the turntable mounting hole. The center of the turntable is fixedly connected to the top of the shaft, and the bottom end of the shaft is arranged in the chassis and connected to the motor. After the turntable is installed, its top surface is flush with the top surface of the chassis.

[0012] Furthermore, a loading area is provided on one side of the chassis, and the station of the turntable corresponding to the loading area is the loading station. The chassis is provided with a first testing mechanism, an automatic gluing mechanism, a second testing mechanism and an automatic unloading and swinging plate mechanism in sequence on the outer side of the turntable. The station of the turntable corresponding to the first testing mechanism is the first inspection station, the station corresponding to the automatic gluing mechanism is the gluing station, the station corresponding to the second testing mechanism is the second inspection station, and the station corresponding to the automatic unloading and swinging plate mechanism is the unloading station.

[0013] Furthermore, a liftable power connector is provided at the position corresponding to the first inspection station and the second inspection station in the chassis, and the power connector corresponds to the wiring port of the turntable. When the test tooling is rotated to the first inspection station or the second inspection station, the power connector in the chassis rises from the bottom to the top, passes through the wiring port and the wiring hole, and is inserted into the power interface of the test tooling, so that the test tooling is powered on.

[0014] After adopting the above scheme, a plurality of workstations corresponding to various test processes of the microphone FPC are evenly spaced on the FPC automatic test turntable of the utility model. By rotating the turntable, each test tool placed on the turntable is rotated to the corresponding test or gluing mechanism for testing or gluing. The wiring port on the turntable and the wiring hole on the fixing seat can be conveniently powered on by the power-on mechanism under the turntable. The entire test process does not require manual transfer of the microphone FPC. Automatic testing of the microphone FPC can be achieved by cooperating with the turntable with the corresponding test mechanism and gluing mechanism, which reduces manual participation as much as possible, improves test efficiency, and avoids damage to the FPC circuit board caused by manual intervention, thereby improving the test yield of the microphone FPC.
