Testing mechanism

Abstract

The invention discloses a testing mechanism, wherein the testing mechanism comprises a mounting seat and at least one floating pressing device, and the mounting seat is provided with at least one first positioning hole; each floating pressing device comprises a pressing block, a connecting piece and a buffer assembly, the pressing block is provided with a second positioning hole communicated with the first positioning hole, and the pressing block is used for sealing a sound hole of the to-be-tested piece; one end of the connecting piece is rotationally arranged in the first positioning hole and the second positioning hole, the pressing block can move in the axial direction of the connecting piece, and the other end of the connecting piece is provided with an external thread; the buffer assembly comprises an elastic piece and an adjusting piece, the adjusting piece is provided with an internal thread in threaded fit with the external thread, and the adjusting piece is in threaded connection with the connecting piece; two ends of the elastic piece are respectively connected with the pressing block and the adjusting piece; and the connecting piece rotates to drive the adjusting piece to be close to or away from the pressing block. According to the invention, the pressure applied to the to-be-tested piece can be adjusted. Meanwhile, the elastic piece can also play a buffering role, so that the influence of the vibration of the testing mechanism on the piece to be tested is reduced.

Description

technical field [0001] The invention relates to the technical field of micro-electroacoustic sensor detection equipment, in particular to a testing mechanism. Background technique [0002] In the assembly and production process of micro-electroacoustic sensors, the soldering accuracy of PCB and shell is relatively high. However, 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. Contents of the in...

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
