Embodiment Construction
[0029] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:
[0030] like figure 1 and image 3 A kind of microphone sorting test device shown, comprises frame 1, is provided with feeding mechanism 2, detection mechanism 3 on the frame, and feeding mechanism 2 includes feeding tray 20, vibrating tray 28, and feeding tray 20 is provided with There are a number of feed branch channels 22 and a feed main channel 23 communicated with the feed branch channel. The feed branch channel can adopt any one between three routes and eight routes according to the feed speed and detection speed. In this embodiment, , in order to ensure continuous and stable feeding, a three-way feed branch is adopted, the feed tray 20 is distributed obliquely, the discharge end of the feed branch 22 is located at the lower end of the feed tray, and the bottom of the feed tray 20 is provided with a linear vibrator 21 , a circular buffer cavi...

The invention relates to the technical field of electronic product detection, and discloses a microphone sorting testing device. The device comprises a rack, a feeding mechanism, and a detection mechanism. The feeding mechanism comprises a feeding dial and a vibrating disk. The detection mechanism comprises a base block, and a sliding plate slidably connected with the top surface of the base block. The sliding plate is provided with a detection gap. A sound hole is arranged right below the detection gap on the base block. Detection pressure fingers are arranged right on the sliding plate. The detection pressure fingers are rotatably connected with the sliding plate. The front end of the detection pressure finger is provided with a detection head. A pressure spring is arranged between the rear end of the detection pressure finger and the sliding plate. The sliding plate is also provided with a lifting cylinder. The shaft end of the lifting cylinder is provided with a horizontal compression bar. The base block is internally provided with a blanking channel communicated with the top surface of the base block. The bottom of the blanking channel is provided with a double-path sorting mechanism. The base block is also provided with a horizontal cylinder used to drive the sliding plate to slide. The device has beneficial effects of rapid and stable feeding, and high detection and sorting efficiency.
Description
technical field [0001] The invention relates to the technical field of electronic product testing, in particular to a microphone sorting and testing device. Background technique [0002] A microphone is also called a microphone or a condenser microphone. At present, the signal-to-noise ratio is usually used as an indicator to judge the quality of the microphone. The signal-to-noise ratio is also called decibel or sensitivity, expressed in DB. After a batch of microphones are processed, it is necessary to sort the DB values of the microphones to select products that meet customer requirements. There is a saying in the microphone industry that "the quality of microphones is obtained through sorting". It can be seen that the detection and sorting of microphones Very important. The current microphone sorting can be divided into manual sorting and automatic sorting. Obviously, manual sorting cannot keep up with the demand; the current automatic sorting is very fine. Selected,...
