Abstract
The utility model discloses a workpiece surface vacuum defoamation device, including the vacuum chamber that is used for placing the work piece, vacuum connected chamber has vacuum pump and highly -compressed air to pour into the shower nozzle into, opening highly -compressed air and injecting the shower nozzle into, in highly -compressed air got into the vacuum chamber fast, work piece rubberizing body open bubble broke because of the quick change of internal -external differential pressure, and the quick high -pressure gas pressure that injects into of while is used in the bubble surface makes the bubble blown brokenly, fine deaeration effect can be reached like this, product surface quality is improved to guarantee the vacuum seal effect of work piece, improve the product quality.
Description
Technical field
The utility model relates to the surperficial colloid de-soak technology using colloid workpiece, is specifically related to surface of the work vacuum defoaming device.
Background technology
For needing the electronic device ensureing inner vacuum, electronic device surface, through colloid embedding process, due to colloid surface easily residual bubble, needs the bubble removal of colloid surface.The use of traditional vacuum deaeration technique has limitation, for the workpiece using epoxy resin encapsulated, resin viscosity is larger, surface tension is large, and embedding thickness is thicker, and bubble is not easy to discharge, because colloid surface tension force not easily breaks after bubble overflows colloid inside, gather colloid surface, be namely gathered in surface of the work, affect surface quality and the vacuum seal effect of workpiece.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides surface of the work bubble easily to remove, and can ensure the surface quality of workpiece and the surface of the work vacuum defoaming device of sealing effectiveness.
To achieve these goals, the technical solution adopted in the utility model is:
Surface of the work vacuum defoaming device, comprises the vacuum chamber for place work piece, and described vacuum chamber is connected with vavuum pump and pressure-air injection nozzle.
Described workpiece is placed on vacuum chamber bottom, and described pressure-air injection nozzle stretches into just to described workpiece setting from described vacuum chamber top.
Described pressure-air injection nozzle area is greater than workpiece top end area.
Described pressure-air injection nozzle is connected with high-pressure air source by tube connector, and the control valve of described pressure-air injection nozzle is located on described tube connector.
Surface of the work vacuum defoaming device, the vacuum transducer also comprising PLC and be located in described vacuum chamber, the control valve on described vavuum pump, vacuum transducer and pressure-air injection nozzle is all connected with PLC.
Described vavuum pump is connected on the sidepiece of described vacuum chamber.
Described workpiece uses epoxy resin encapsulated.
The utility model has the advantage of: surface of the work vacuum defoaming device, open vacuum pump evacuation, in vacuum chamber, vacuum reaches and closes after setting value or vacuum pump evacuation reach setting-up time, closes vavuum pump; Open pressure-air injection nozzle, pressure-air enters in vacuum chamber fast, and surface of the work bubble breaks because inside and outside differential pressure changes fast, and the high-pressure gas pressure simultaneously injected fast acts on bubble surface and bubble is blown brokenly; Two to four circulations just can reach well row's bubble effect so repeatedly, improve product surface quality, to ensure the vacuum seal effect of workpiece, improve product quality.
Accompanying drawing explanation
Mark in the content expressed each width accompanying drawing of the utility model description below and figure is briefly described:
Fig. 1 is the structural representation of the utility model surface of the work vacuum defoaming device.
Mark in above-mentioned figure is:
1, pressure-air injection nozzle, 2, vacuum chamber, 3, workpiece, 4, vavuum pump, 5, epoxy resin.
Detailed description of the invention
Contrast accompanying drawing below, by the description to optimum embodiment, detailed description of the invention of the present utility model is described in further detail.
As shown in Figure 1, surface of the work vacuum defoaming device, comprises the vacuum chamber 2 for place work piece 3, and vacuum chamber 2 is connected with vavuum pump 4 and pressure-air injection nozzle 1.Open vavuum pump 4 to vacuumize, in vacuum chamber 2, vacuum reaches and closes after setting value or vavuum pump 4 vacuumize and reach setting-up time, closes vavuum pump 4; Open pressure-air injection nozzle 1, pressure-air enters in vacuum chamber 2 fast, and workpiece 3 blibbing breaks because inside and outside differential pressure changes fast, and the high-pressure gas pressure simultaneously injected fast acts on bubble surface and bubble is blown brokenly; Two to four circulations just can reach good deaeration effect so repeatedly, improve product surface quality, to ensure the vacuum seal effect of workpiece 3, improve product quality.
Workpiece 3 is placed on vacuum chamber 2 bottom, and pressure-air injection nozzle 1 stretches into from vacuum chamber 2 top and just arranges workpiece 3; Pressure-air injection nozzle 1 is positioned at vacuum chamber 2, and just arranges workpiece 3, can make to enter gases at high pressure snap action in vacuum chamber 2 like this on workpiece 3 surface, to reach better deaeration effect.
The shower nozzle area of pressure-air injection nozzle 1 is greater than workpiece 3 top end area; To ensure that the vacuum gas entered in vacuum chamber 2 acts on workpiece 3 surface on a large scale, play the effect of rapidly defoaming.
Pressure-air injection nozzle 1 is connected with high-pressure air source by tube connector, and the control valve of pressure-air injection nozzle 1 is located on tube connector; The quick and convenient control of control valve energy enters the gases at high pressure in vacuum chamber 2.
Surface of the work vacuum defoaming device, the vacuum transducer also comprising PLC and be located in vacuum chamber 2, the control valve on vavuum pump 4, vacuum transducer and pressure-air injection nozzle 1 is all connected with PLC.
After vavuum pump 4 is opened, the vacuum in vacuum chamber 2 is fed back to PLC by vacuum transducer, and in vacuum chamber 2, vacuum reaches closedown setting value, and PLC sends instruction control vavuum pump 4 and closes; The control valve that PLC sends instruction control pressure-air injection nozzle 1 is simultaneously opened, and when in vacuum chamber 2, vacuum reaches and opens setting value, PLC sends the control valve closedown that instruction controls pressure-air injection nozzle 1; By the control of PLC, realize the automatically working of workpiece 3 vacuum defoaming device, to improve deaeration efficiency and operation ease.
Vavuum pump 4 is connected on the sidepiece of vacuum chamber 2, and vacuum chamber 2 sidepiece is provided with the exhaust outlet be connected with vavuum pump 4, and vavuum pump 4 mounting arrangements is convenient.
Workpiece 3 uses epoxy resin 5 embedding, to ensure the vacuum seal effect of workpiece 3.
