Abstract
The invention discloses a vacuum defoaming device. The vacuum defoaming device comprises a vacuum chamber used for accommodating workpieces; the vacuum chamber is connected with a vacuum pump and a high pressure air injection nozzle; the high pressure air injection nozzle is opened, and high pressure air enters into the vacuum chamber quickly, so that foams on the surfaces of colloids on the workpieces break because of rapid change of inside-outside pressure different, and the high pressure gas which enters into the vacuum chamber quickly is applied onto the surfaces of the foams so as to broke the foams. Excellent defoaming effect can be achieved; product surface quality is increased; vacuum sealing effect of the workpieces is ensured; and product quality is improved.
Description
Technical field
The present invention relates to the surperficial colloid de-soak technology using colloid workpiece, be specifically related to 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.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide surface of the work bubble easily to remove, the surface quality of workpiece and the vacuum defoaming device of sealing effectiveness can be ensured.
To achieve these goals, the technical solution used in the present invention is:
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.
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 invention has the advantages that: 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.

Detailed description of the invention
Contrast accompanying drawing below, by the description to optimum embodiment, the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, 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.
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.
Obvious specific implementation of the present invention is not subject to the restrictions described above, as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out, all within protection scope of the present invention.
