Problems solved by technology

However, the structure of the mobile phone speaker net itself is relatively small, and the diameter of the sound-transmitting through hole is even smaller, so there are great difficulties in manual visual inspection, which will consume a huge amount of human labor.

Abstract

The invention relates to a mobile phone horn net sound transmission detecting device which comprises a bottom plate, a feeding and push-in mechanism, a sound proof box lifting and ejector mechanism, adetecting mechanism and a receiving box. The sound proof box lifting and ejector mechanism is located on the upper end surface of the bottom plate. The feeding and push-in mechanism, the detecting mechanism and the receiving box are all located on a bracket of the bottom plate. The feeding and push-in mechanism, the detecting mechanism and the receiving box are successively arranged along the bracket from bottom to top. The feeding and push-in mechanism comprises a feed channel and a push-in cylinder. The push-in cylinder is located on one side of the tail end of the feed channel. The sound proof box lifting and ejector mechanism comprises a screw slide rail module and a sound proof box. A speaker net card slot is arranged on the side of the sound proof box. An audio and an ejection cylinder are arranged in the sound proof box. According to the invention, the device can automatically detect a mobile phone speaker net by means of sound transmission detecting, so as to determine whethersound transmission through holes are partially blocked; the labor intensity is reduced; and the detection accuracy is improved.

Description

technical field [0001] The invention relates to the field of sound transmission detection, in particular to a sound transmission detection device for mobile phone speaker nets. Background technique [0002] The mobile phone speaker net, also known as the mobile phone handset net, refers to the dust-proof net cover on the mobile phone speaker, so it is also called the mobile phone horn cover. According to the material, it is divided into plastic mobile phone speaker net and hardware mobile phone speaker net. [0003] After the production and processing operation of the mobile phone speaker net is completed, it needs to be sprayed with color paint for visual aesthetics. After the spraying is completed, the small-sized sound-transmitting through holes on the mobile phone speaker net may be partially blocked by the dried paint, and the sound permeability of the blocked sound-transmitting through holes will be greatly weakened, resulting in the failure of the mobile phone speake...
