Detailed description of the invention
The utility model is described in further detail with example with reference to the accompanying drawing.
Fig. 1 is the schematic diagram of the vacuum engagement device of the utility model.
Specific embodiment
Referring to Fig.1, a kind of vacuum engagement device of the utility model, including it is attracted module 1 and vacuum pump, it is attracted module 1
The elastical cloth 3 of the frame 2 covered and the one side for being covered in frame 2, the one side sealed connection of elastical cloth 3 and frame 2 are enclosed including being formed
One-sided open structure is formed, one-sided open structure setting has a coating space 4 for accommodating bridge, and the inside of frame 2 is towards packet
It covers space 4 and is provided with suction hole 5 through frame 2, the vacuum lead 6 for connecting vacuum pump is provided among suction hole 5.
Specifically, it after the bridge for adhesive surface being coated with glue is placed on qin case, is placed on qin case simultaneously using module 1 is attracted
Coat bridge, under the vacuum action of vacuum pump, air in coating space 4 can from suction hole 5 along vacuum lead 6 and
It is pulled out, therefore, elastical cloth 3 can be collapsed gradually, until elastical cloth 3 is fitted tightly over the surface of bridge, so, in atmospheric pressure
Under effect, bridge can be tightly pressed together on qin case.Therefore, the vacuum engagement device of the utility model, compared to manpower pressure
Conjunction is better able to bridge to be firmly bonded on qin case, and can guarantee the consistency of pressing dynamics, to effectively solve
The certainly hidden danger that bridge is got loose.
Wherein, referring to Fig.1, be provided on frame 2 in one-sided open structure for reinforce being attracted module 1 and qin case it
Between leakproofness elastic pressing layer 21.Specifically, elastic pressing layer 21 is mainly made of rubber, the shape of elastic pressing layer 21
It is consistent with the shape of frame 2, and elastic pressing layer 21 is tightly connected along the edge and frame 2 of frame 2.When actuation mould
When block 1 is placed on qin case and coats bridge, elastic pressing layer 21 can be in contact with qin case, when vacuum pump carries out vacuumizing place
When reason, with the reduction of 4 inner air of coating space, elastical cloth 3 can be collapsed persistently, and frame 2 also can be in the work of atmospheric pressure
It is pressed on qin case downwards with lower, since elastic pressing layer 21 has good elasticity capacity, being attracted module 1 can be with
The surface of qin case is sealed contact.As one can imagine when the one side out-of-flatness that the frame 2 of solid structure is in contact with qin case is deposited
At gap, extraneous air can be continued into inside coating space 4 from the gap, therefore will affect inside coating space 4
Vacuum degree, be attracted module 1 to the adhesive effect of bridge to reduce.And the application is provided with elastic pressing layer 21, so that inhaling
Molding block 1 can be sealed with the surface of qin case to be contacted, and the vacuum degree inside coating space 4 is prevented to be affected, so as to
Enough adhesive forces improved to bridge.
Wherein, referring to Fig.1, the inside of frame 2 is provided with suction pipe along frame 2, and the inside of frame 2 is empty towards cladding
Between 4 be additionally provided with connection suction pipe assisted inhalation hole, assisted inhalation hole pass through inside and air-breathing of the suction pipe in frame 2
Hole 5 is connected.Specifically, the quantity in assisted inhalation hole can be multiple, respectively along frame 2 inside towards coating space 4
Setting.When the quantity in assisted inhalation hole is more, the efficiency of vacuumize process is higher, therefore the operating efficiency for bonding bridge is higher.
When vacuum pump extracts the air inside coating space 4 by vacuum lead 6, the air inside coating space 4 can be simultaneously
It is discharged from suction hole 5 and assisted inhalation hole, and the air being discharged from assisted inhalation hole converges at air-breathing by suction pipe
Hole 5 is transferred among vacuum pump finally by vacuum lead 6, therefore, when can larger save the processing vacuumized
Between, to substantially increase production efficiency.
Wherein, referring to Fig.1, being attracted module 1 further includes the elastic press for compressing bridge；It is attracted module 1 and coats bridge
When, elastic press is among coating space 4.Specifically, elastic press is mainly made of rubber, belongs to the portion being independently arranged
Part.Since different guitars or violin have different size of bridge, and when needs are bonded in lesser bridge on qin case
When, due to the height limitation of frame 2, may have elastical cloth 3 cannot coat the case where compressing bridge.In this case,
Using elastic press, the distance between bridge and elastical cloth 3 can reduce, that is, elastical cloth 3 has been thickeied, so, work as benefit
When carrying out vacuumize process with vacuum pump, the elastical cloth 3 constantly collapsed can be pressed on elastic press first, and elastic press
Then the atmospheric pressure effect passed over by elastical cloth 3 on bridge, so as to which lesser bridge is bonded securely
On qin case, to improve the using flexible of the vacuum engagement device of the utility model, enable to be applicable in wider array of
The scope of application.
Wherein, referring to Fig.1, the switch 7 for on-off vacuum lead 6 is provided among vacuum lead 6.Specifically,
Switch 7 can flexibly and easily ON/OFF vacuum lead 6, also, switch 7 can be turn-knob switch or key switch.When
When needing to carry out vacuumize process, 7 need to be only turned on the switch, vacuum pump can carry out vacuum pumping by vacuum lead 6.And
When completing the adhesion process to bridge, it is first shut off switch 7, at this point, vacuum pump cannot continue to extract inside coating space 4
Air, as long as therefore slightly lift any position of frame 2, external air can be rapidly introduced among coating space 4,
So that being attracted module 1 can be raised.Further, since the setting of switch 7, so that completing the adhesion process to bridge every time
When, it does not all need to close vacuum pump, only need to turn off the switch 7, therefore, can be avoided frequent unlatching/closing vacuum pump, thus
Good protection can be played to vacuum pump, prevent the service life that vacuum pump is influenced because of frequent unlatching/closing vacuum pump.
In addition, being additionally provided in the direction of the inside of frame 2 towards coating space 4 for detecting inside coating space 4
The vacuum transducer of vacuum degree is integrated with the charactron for showing the vacuum degree inside coating space 4 on switch 7, and
For the vacuum degree information detected by vacuum transducer being transferred to the data line of charactron, then along vacuum lead
6 are laid.Under the mating reaction of vacuum transducer and charactron, user can be true inside real-time monitoring coating space 4
Reciprocal of duty cycle.When vacuum degree inside coating space 4 is excessive, user can by adjusting vacuum pump output power and reduce cladding
Vacuum degree inside space 4, so as to avoid the case where damaging bridge by pressure since pressure is excessive；When inside coating space 4
Vacuum degree it is too small when, user can by adjusting vacuum pump output power and increase the vacuum degree inside coating space 4, from
And bridge is preferably bonded on qin case.
Be above to the utility model it is preferable implementation illustrated, but the utility model be not limited to it is above-mentioned
Embodiment, those skilled in the art can also make various be equal without departing from the spirit of the present invention
Deformation or replacement, these equivalent deformations or replacement are all included in the scope defined by the claims of the present application.
