Abstract

The invention discloses a testing mechanism. Wherein, the test mechanism includes a mounting base and at least one floating pressing device, and the mounting base is provided with at least one first positioning hole; each floating pressing device includes a pressing block, a connector and a buffer assembly, and the pressing block is provided with a first positioning hole. The second positioning hole connected to the hole, the pressure block is used to seal the sound hole of the test piece; one end of the connecting piece is rotated in the first positioning hole and the second positioning hole, and the pressure block can move along the axial direction of the connecting piece, The other end of the connecting piece is provided with an external thread; the buffer assembly includes an elastic piece and an adjusting piece, the adjusting piece is provided with an internal thread matched with the external thread, and the adjusting piece is threadedly connected with the connecting piece; the two ends of the elastic piece are respectively connected with the pressure block and the The adjustment piece is connected; wherein, the rotation of the connection piece drives the adjustment piece to approach or move away from the pressure block. The invention can adjust the size of the pressure on the test piece. At the same time, the elastic member can also play a buffering role, reducing the impact of the vibration of the testing mechanism on the test piece.

Description

Technical field [0001] The present invention relates to the technical field of microelectric acoustic sensor detection devices, particularly to a testing apparatus. Background [0002] In the assembly and production process of micro-electroacoustic sensors, the solder accuracy of PCB and housing is relatively high, but even the most advanced welding process cannot guarantee 100% yield. Poor welding of the product will cause the product to leak sound and affect the performance of the product. Being able to test whether the product leaks sound is a problem that the field will soon face, especially in the automatic testing process of the product, the pressure of the parts in contact with the product will directly affect the test results of the product, and the pressure is too large, which will cause the sound leakage product to not be detected; the pressure is too small, and the product sound hole is poorly sealed, resulting in misjudgment.

Problems solved by technology

[0002] In the assembly and production process of micro-electroacoustic sensors, the soldering precision requirements of PCB and shell are relatively high, but no matter how advanced the soldering process is, it cannot guarantee a 100% yield

Poor welding of the product will cause sound leakage of the product and affect product performance

Being able to test whether the product has sound leakage is an upcoming issue in this field, especially in the process of automatic testing of large products, the pressure of the parts in contact with the product will directly affect the test results of the product, and excessive pressure will cause leakage. Acoustic products cannot be detected; if the pressure is too small, the sound hole of the product is not well sealed, resulting in misjudgment
