Provided with the upper mould 8 being connected with lift cylinder 7 below the lift cylinder 7 that inductor 3 is electrically connected, the top plate of casing 2；Upper mould 8 has
First accommodating chamber of lower ending opening, magnetic valve is connected with first gas conveyance conduit and connected by the first gas conveyance conduit
First accommodating chamber, lower mould 4 has the second accommodating chamber that upper end open and the openings of sizes are matched with the size of loudspeaker 15 to be measured；Water level
Box 5 connects the second accommodating chamber；Loudspeaker gas leakage automatic detection device also includes buffer 9, and the one end of buffer 9 is fixed on casing 2
Top plate below, the other end is fixed on the first accommodating chamber；Loudspeaker 15 to be measured are positioned over the overthe openings of the second accommodating chamber, and pass through
Inner seal ring 10 is sealed；Lower mould 4 is additionally provided with the exterior seal ring closed with the first accommodating chamber.
In order that more preferably, the quantity of exterior seal ring is set to two for upper mould 8 is descending when being closed as lower mould 4 sealing effectiveness, point
Not Wei the first exterior seal ring 11 and the second exterior seal ring 12, the second exterior seal ring 12 be located at the first exterior seal ring 11 periphery, enter
One step reaches the effect being fully sealed.Start lift cylinder 7 using priming inductor 3 and avoid operating personnel and often touch the button and make
Into finger fatigue, it is only necessary to which both hands are slipped over into inductor, lift cylinder 7 can start work.In order to avoid upper mould 8 is in descending mistake
The hand of operator is pressed onto in journey, the quantity for setting priming inductor 3 is two, operator must both hands two startups of sensing simultaneously
Lift cylinder 7 just starts work during inductor 3, and preferred embodiment is that two priming inductors 3 are separately positioned on to the two of lower mould 4
Side.Priming inductor 3 can be but not limited to model MB-027 human body infrared inductive switch.
It can not be impacted in view of loudspeaker 15 to be measured by too big air pressure, in order to avoid air pressure in the first accommodating chamber of upper mould 8
Sound film that is excessive and washing out loudspeaker 15 to be measured, digital display manometer 13 is additionally provided with the lateral wall of casing 2, and magnetic valve is also associated with second
Gas transmission pipeline, magnetic valve connects digital display manometer 13 by second gas conveyance conduit, and digital display manometer 13 also connects
Connect controller.When magnetic valve is opened, gas is divided into two-way, be all the way into upper mould 8 the first accommodating chamber to loudspeaker 15 to be measured
Realize that automatic leakage air detects that another road is the pressure that gas is shown by digital display manometer 13, if the now pressure of gas
Value is higher than setting value, and the feedback signal of digital display manometer 13 to controller, controller output alarm signal to alarm, alarm is carried
Show alarm.
Multiple foots pad 14 are set in the lower section of bottom plate in addition, four angles preferably below bottom plate set a foot pad respectively
14, an anti-skidding firm effect is started to whole loudspeaker gas leakage automatic detection device.
The loudspeaker gas leakage automatic testing method of the present embodiment, including step are as follows：
Step one：In the lower mould 4 that loudspeaker 15 to be measured are placed into loudspeaker gas leakage automatic detection device, loudspeaker 15 to be measured are aligned
The aperture position of second accommodating chamber, and sealed the accommodating chamber of loudspeaker 15 and second to be measured with inner seal ring 10；
Step 2：Operating personnel will be manually placed into priming inductor 3, thus touch priming inductor 3, and priming inductor 3 is felt
Signal should be arrived, lift cylinder 7 is descending and drives upper mould 8 descending, the buffer 9 that one end is fixed on the first accommodating chamber is pressed onto treats at first
Loudspeaker 15 are surveyed, loudspeaker 15 to be measured are positioned compression, and upper mould 8 is continued traveling downwardly to the exterior seal ring on lower mould 4 and fitted completely so that
First accommodating chamber is fully sealed with the external world；
Step 3：The magnetic valve in casing 2 is opened, first that digital display manometer 13 and upper mould 8 are deliver a gas to respectively is held
Chamber is received, if the pressure value that digital display manometer 13 is shown is higher than setting value, feedback signal to controller, controller control alarm
Alarm；Pressurize is carried out to the gas in the first accommodating chamber in preset time, preset time is 1-2 seconds, preferably but is not limited
In 1.5 seconds, if loudspeaker to be measured 15 have gas to spill, into the 4th step, if loudspeaker to be measured are spilt without gas, illustrate that loudspeaker are closed
Lattice, detection of end；
Step 4：The gas that loudspeaker 15 to be measured are spilt flows into water level box 5 by the second accommodating chamber, promotes the water of water level box 5
Post is moved；
Step 5：Water level sensor 6 sends signal, controller control after sensing the movement of the water column of water level box 5 to controller
Alarm processed sends alarm, points out this loudspeaker to be measured unqualified, detection of end.
In the present embodiment, mould 8 compresses the sealed time for 0.5 second with lower mould 4 in the descending drive of lift cylinder 7, is passed through gas
Dwell time in body to the first container is 1.5 seconds, equally, and the time that lift cylinder 7 rises after the completion of detection is 0.5 second,
Therefore detect a loudspeaker 15 to be measured altogether the used time be 2.5 seconds or so, when production can reach 1500PCS, efficiency high is greatly reduced
Labour, saves manpower, realizes full-automatic production, and accuracy rate is greatly promoted, and reduces False Rate, and practical value is high, pushes away
Wide property is strong.
It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other various
It is corresponding to change and deformation, and all these change and deformation should all belong to the protection domain of the claims in the present invention
Within.
