Description
Technical field
The present invention relates to and relate to microphone processing technique field, particularly relate to the automatic Wrapping apparatus of a kind of electret capacitance microphone.
Background technology
Microphone, be again miaow head or condenser microphone, it generally comprises shell, in shell, back pole plate is installed, three-piece, PCB, need after assembling to carry out bound edge to the openend of shell, thus form complete product, bound edge requires favorable sealing property, PCB non-loosening, microphone case is cylindric, in prior art, usually be all grab in chuck to the microphone manipulator clamping assembled to one three, three grab chuck clamping microphone after high speed rotating, then by a crimping bar around center rotating near and be pressed in shell aperture edge, when microphone 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, microphone ejected.In this equipment of prior art, there is shortcomings: 1) manipulator captures microphone 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, microphone processing 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 microphone 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 microphone is all to small-sized development, its diameter of little microphone 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 microphone 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 automatic Wrapping apparatus of the electret capacitance microphone improved the quality of products simultaneously.
To achieve these goals, the present invention adopts following technical scheme:
The automatic Wrapping apparatus of a kind of electret capacitance microphone, comprise frame, described frame end face is provided with substrate, substrate is provided with feeding-passage, guide and limit cover, liftable push rod is provided with in described guide and limit cover, the top of described frame is provided with the supporting bracket with substrate-parallel, described supporting bracket is provided with bound edge seat, described bound edge seat comprises the fixing fixed cover of lower end and supporting bracket, be located at the cylindrical piece in fixed cover, the inwall of described fixed cover is circumferentially provided with some vertical slide rails, the lateral surface of described cylindrical piece is provided with the sliding shoe coordinated with slide rail, vertical rotating shaft is provided with in described cylindrical piece, the lower end of described rotating shaft is provided with rotation edge covering mechanism, the upper end of described fixed cover is provided with end cap, stage clip is provided with between described end cap and cylindrical piece upper end, parallelly above supporting bracket be provided with motor mounting plate, the upper end of described rotating shaft is provided with driven gear, the axle head of described motor is provided with the driving gear engaged with driven gear.
