Description

A kind of condenser microphone sealed in unit
Technical field
The present invention relates to and relate to electronic product machining technical field, particularly relate to a kind of condenser microphone sealed in unit.
Background technology
Miaow head, be again microphone or condenser microphone, it generally comprises shell, in shell, back pole plate is installed, three-piece, PCB, need after assembling to carry out edge sealing (being also bound edge or crimping) to the openend of shell, thus form complete product, bound edge requires favorable sealing property, PCB non-loosening, miaow head shell is cylindric, in prior art, usually be all grab in chuck to the miaow head manipulator clamping assembled to one three, three grab high speed rotating after chuck clamping miaow head, then by a crimping bar around center rotating near and be pressed in shell aperture edge, when miaow head rotates, the circular arc of crimping club head makes shell edge inwardly curling and is pressed in around PCB to realize bound edge, finally unclamp three grab chuck and by push rod, the miaow crown gone out.In this equipment of prior art, there is shortcomings: 1) manipulator captures miaow head by suction nozzle, suction nozzle needs to be connected by gas circuit with air compressor machine, gas in air compressor machine contains the steam of high level, the processing of miaow head is very high to environmental requirement, and need dustless, dry environment, especially back pole plate is with electric charge, steam can have a strong impact on the electric charge on back pole plate, thus causes final products unstable properties; 2) after miaow head is grabbed chuck location by three, single crimping bar is pressed in shell edge, discontinuity, affects product appearance on the one hand, and after product bound edge, sealing property can decline on the other hand; 3) because present miaow head is all to small-sized development, little its diameter of miaow head is at about 4mm, therefore in crimping process, the aligning accuracy of crimping bar and shell rim requires very high, and three grab chuck in frequent clamping, release process and can wear and tear, thus it is cheap to cause pivot to exist, and finally affects bound edge quality; 4) no matter is at present import equipment, or home equipment, device structure is complicated, and inside exists a large amount of motors, cylinder, sensor, bulky, cost is high.
Chinese patent Authorization Notice No.: CN201446173U, authorized announcement date on May 5th, 2010, discloses a kind of automatic banding device, comprising: frame; Element lock means, element lock means is arranged on lowering or hoisting gear, and lowering or hoisting gear is arranged in described frame; Rotate edge banding apparatus, be arranged in frame, be positioned at the top of described element lock means, rotate edge banding apparatus and be at least provided with an edge sealing head near one end of element lock means; When element enters into element lock means, element lock means moves upward to edge sealing head, the rotary motion of edge sealing head is by curling for the opening of element metallic shell sealing, realize the automatic edge sealing of miaow head metal shell, improve operating efficiency, achieve the gentle edge sealing to element simultaneously, improve the quality of product, save manpower and materials.Its weak point is, in this structure, rigid contact between shell and edge sealing head, when each outer cover height exists size difference, will cause the pressure between edge sealing head and shell there are differences, affect homogeneity of product, thus affect sealing, reduces product quality.
Summary of the invention
The present invention is in order to solve the aforementioned problems in the prior, provide that a kind of aligning accuracy is high, bound edge homogeneous quality is good, according to outer cover height difference automatic fine tuning pressure, each product bound edge pressure stability can be ensured, the condenser microphone sealed in unit improved the quality of products simultaneously.
