Description

Lifting falling mechanism and earphone tester Technical Field The utility model relates to the technical field of earphone drop tests, in particular to a lifting drop mechanism and an earphone tester. Background Drop test is an essential important link in the production process of high-end headphones, and has important significance for improving the quality of the headphones. At present, most manufacturers adopt a manual taking mode to carry out drop test, the mode can increase the labor intensity of staff, the consistency of drop height and drop posture is relatively poor, manual counting is easy to make mistakes, and therefore, the comparability and consistency of each test period are difficult to ensure by manually taking the earphone to carry out drop test. Disclosure of utility model In order to overcome the defects in the prior art, the lifting falling mechanism provided by the utility model ensures the stability of the initial posture of a product to be tested in the falling process through the matching of the discharging platform and the clamping assembly, ensures the consistency of the falling height of the product to be tested each time in a falling seating mode through the lifting of the first lifting mechanism, can realize the falling requirements of different products at different heights according to requirements, can ensure the accuracy of the falling times in a system automatic counting mode, avoids the error of manual counting, can double empty multiple products, has strong applicability, and can rotate to different angles for the product to be tested clamped by the falling seat and the clamping assembly so as to realize multi-azimuth falling test. The utility model further provides an earphone testing machine, wherein the CCD visual detection mechanism is convenient for photographing and detecting the earphone to screen out the earphone which does not need to be subjected to drop test, drop operation is not triggered, so that working efficiency is improved, drop height controllability of the earphone is realized through setting of the lifting drop mechanism, consistency of drop postures is guaranteed, automatic cyclic drop of the earphone can be realized, drop frequency accuracy is guaranteed, manual working intensity and risk of errors of manual drop operation are effectively reduced, multiple products can be also used, applicability is improved, and the detachable setting of a drop table is convenient for adopting different impact materials according to requirements, so that drop test diversity is provided. The utility model aims to achieve the aim, and the aim is achieved by the following technical scheme: the utility model provides a lifting drop mechanism, including falling the first elevating system who takes off and take off, control falls to take off and go up and down, fall and take off and set up blowing platform, clamping assembly on taking off, the blowing platform is located clamping assembly's downside, the blowing platform includes two mobilizable minute platforms, the first cylinder of two minute platform intervals of control, clamping assembly includes two clips that set up relatively, the second cylinder of two clip intervals of control.
