Description
Technical field
The present invention relates to electronic product detection technique field, more particularly to a kind of miaow head testing, sorting machine.
Background technology
Miaow head is called microphone, generally judges miaow head quality by the use of signal to noise ratio as index at present, signal to noise ratio is also decibel
Or sensitivity, represented with DB.A collection of miaow head process after, it is necessary to sorted to miaow head DB values, sub-elect and meet client and want
The product asked, miaow head industry, which has, to be in short called " miaow head quality is by sorting out ", it is seen then that detection, the sorting of miaow head
It is extremely important.Present miaow head sorting can be divided into sorting and automatic sorting manually, it is clear that sorting does not catch up with demand completely manually；Mesh
Preceding automatic sorting sorting is very fine, once sorts and just the miaow head in the range of various sensitivity while sorts out, such as one
Miaow head is criticized after once sorting, is directly divided into a variety of models such as 35DB-40DB, 40DB-45DB, 45DB-50DB, 50DB-55DB
Enclose, and client only needs the product in one of scope, it is very thin due to classifying, so as to cause each miaow head detection time
Extend, also miaow head is accurately assigned in corresponding magazine after detection, the time is longer, causes to detect miaow head in the presence of wait, sorting
Efficiency is low, it is difficult to the product to meet the requirements of the customers is sub-elected in a short time, and the storage for a long time of miaow head can cause DB values inclined
Move, so if after the sorting of a collection of miaow head, fall again without sale in time, in order to ensure quality before follow-up sales, it is also necessary to again
Sorting.
Chinese patent Authorization Notice No.：CN203265084, authorized announcement date on November 6th, 2013, disclose it is a kind of entirely from
Dynamic digital microphone testing, sorting machine, including feed mechanism, rotary feeding mechanism, mechanism for testing, classification blanking mechanism and rewinding
Mechanism, wherein feed mechanism include the vibrating chassis being arranged in first panel, and hopper is provided with the vibrating chassis, is also wrapped
The track on linear vibrator is included, one end of the track is connected with the outlet of foregoing hopper.Its weak point is this kind
Although automatic fraction collector is with manual concentration criterion compared with efficiency greatly improves, but microphone can only one by one be detected, sorted, knot
Structure complexity, the efficiency of separation still can not meet demands.
The content of the invention
The present invention is in order to overcome the shortcomings of that miaow head grouping system efficiency of the prior art is low, there is provided one kind is greatly improved
The detection of miaow head, the efficiency of separation, the miaow head testing, sorting machine for the product that meets the requirements of the customers can be quickly sub-elected in a short time.
To achieve these goals, the present invention adopts the following technical scheme that：
A kind of miaow head testing, sorting machine, including frame, frame are provided with feeding mechanism, testing agency, described charger
Structure includes entry table, linear vibrator, if described entry table is provided with main line charging by-path, described testing agency includes base
Block, the sliding panel being slidably connected with matrix top surface, the sliding panel are provided with some and charging branch at it close to one end of entry table
The detection breach of road docking, inspection is provided with positioned at the sound hole that is arranged right below of detection breach, the surface of the sliding panel on matrix
Pressure measurement refers to, and the detection pressure refers to be rotatablely connected with sliding panel, and the front end that refers to of detection pressure is provided with detector, rear end that detection pressure refers to and
Stage clip is provided between sliding panel, lift cylinder is additionally provided with the sliding panel, the shaft end of lift cylinder is provided with horizontal struts, works as liter
When sending down abnormally ascending cylinder shaft is stretched out, horizontal struts are pressed in the rear end that detection pressure refers to, and the blanking with the insertion of matrix top surface is provided with the matrix
Passage, the bottom of blanking channel are provided with two-way sorting mechanism, and the horizontal air cylinder for driving sliding panel to slide is additionally provided with matrix,
When horizontal gas cylinder shaft be in retraction, stretch out two extreme positions when, detection breach respectively positioned at sound hole, blanking channel just on
Side.
Detector is connected by data wire with detector, is first set the DB value scopes that miaow head needs to sort, is fallen in the scope
Interior product is customer demand product, and product within the range is not uncertain product, to be realized quickly in a large amount of miaows in this structure
Customer demand product are sub-elected in head.Detection breach on sliding panel is moved to directly over sound hole in the presence of horizontal air cylinder, this
When detect breach and dock with feeding the discharge end of by-path, lift cylinder shaft extension goes out, and depression bar is pressed in the rear end that refers to of detection pressure, detects and presses
The front end of finger is sticked up, and the sound of certain frequency is continually fed into sound hole, and miaow head enters detection breach, lifting from charging by-path
Cylinder axis retraction, detection pressure refer in the presence of stage clip, and the detector decline in detection pressure finger portion is being pressed in the pcb board of miaow head just
Negative pole, detects miaow head builtin voltage, and magnitude of voltage is converted into DB values by detector automatically（Two kinds are only existed after each miaow head detection
State：Customer demand product, uncertain product）, detector separates with miaow head, and horizontal air cylinder drives sliding panel translation so that detection lacks
Intraoral miaow head enters in blanking channel, according to after detecting before to the judgment value of miaow head, the two-way sorting mechanism of blanking channel
Passage corresponding to opening, the miaow head after detection are fallen in two kinds of magazines, and the miaow head after sorting only has customer demand product, do not known
Product, unnecessary sorting action is reduced, the product of customer demand can be sub-elected within the extreme time, sets remaining DB value scope,
Uncertain product are sorted again, so as to realize subdivision；Thinking change, multiple miaow heads grouping system simultaneously are sorted, as long as charging
With it is upper, can realize that ten products even more products while sort in theory, single miaow head every time sorting it is required when
Between be the 1/5 of current automatic separation equipment, it is assumed that triple channel is fed, the sorting of a collection of miaow head into 5 DB sections, comprehensive sorting effect
Rate is three times of current automation equipment, is the 15 of current automation equipment to product selecting efficiency in customer demand DB sections
Times, detector heating influences whether accuracy of detection, and detection is only the judgement of two kinds of situations every time in this structure, to detector
Burden it is small, detector internal data processing module is not easy to generate heat, and detection is more stable.
Preferably, described matrix is provided with dovetail guide, the bottom of the sliding panel is provided with to be coordinated with dovetail guide
Dovetail raised line.Dovetail guide, the cooperation of dovetail raised line are stable, reliable.
Preferably, bottom of the frame is provided with a source of sound, a source of sound is corresponded with sound hole by sound tube connect respectively.
Multiple sound holes share a source of sound, ensure that testing conditions are consistent, so as to avoid the detection error that source of sound different band itself is come, improve
Accuracy of detection.
Preferably, the front end that described detection pressure refers to extends to form contiguous block, the outer end of contiguous block is provided with horizontal neck,
The U-shaped breach through horizontal neck is additionally provided with contiguous block；Described detector includes chaining pin, chaining pin fixed plate, described survey
