Brief description of the drawings
Fig. 1 is the schematic diagram that hand pastes the device of technique that is used for of embodiments of the present invention.
Fig. 2 pastes the flow chart of technique for the hand of embodiments of the present invention.
Embodiment
Below in conjunction with the accompanying drawings, the present invention is further illustrated by way of embodiment, but therefore not incite somebody to action this
Invention is limited among described scope of embodiments.
As shown in figure 1, including for the device 1 that hand pastes technique：In vacuum bag film 2, the vacuum bag film
With flow-guiding mouth 7；Resin receiver 3, the top of the resin receiver 3 offers spaced tree
Fat inflow entrance 4 and air outlet slit 5, the resin inflow entrance 4 and the air outlet slit 5 are received with the resin
The inside connection of device 3, the resin inflow entrance 4 is connected by the first exhaust tube 6 with the flow-guiding mouth 7；Very
Empty pump 8, the vavuum pump 8 is connected by the second exhaust tube 9 with the air outlet slit 5.
As shown in Fig. 2 the hand paste technique of the present embodiment comprises the following steps：
Step 100：Glass layer of cloth 10 is laid on presumptive area.
The glass layer of cloth 10 is to constitute one of raw material of hand paste.For example, passing through vacuum in blade
, it is necessary to be repaired to some positions of blade after perfusion basic forming, hand paste operation is typically chosen, when
When carrying out hand paste operation, glass layer of cloth 10 is laid on presumptive area, the presumptive area refers to needs
The region of hand paste operation is carried out, the area in the region is not restricted.Typically laid by glass layer of cloth 10
Before presumptive area, glass layer of cloth 10 is cut into the size being adapted with presumptive area.
Step 200：Make glass layer of cloth described in resin impregnated.
Resin is coated in glass layer of cloth with any of scraper plate, wool roller, brush, bubble roller instrument
On 10, so that resin impregnated glass layer of cloth 10.
Step 300：Release cloth, flow-guiding screen, vacuum bag film 2 are covered in glass layer of cloth 10 successively.
Usually, by release cloth, flow-guiding screen, vacuum bag film 2 be covered in successively glass layer of cloth 10 it
Before, scrape off the unnecessary resin on the surface of glass layer of cloth 10.Vacuum bag film 2 is covered in glass-fiber-fabric
After on layer 10, with the edge of rubber belt sealing vacuum bag film 2, to cause the inside of vacuum bag film 2 close
Envelope.
Step 400：The inside of vacuum bag film is vacuumized, and exports unnecessary resin.
Using the above-mentioned device 1 that technique is pasted for hand, so that the inside of vacuum bag film 2 passes through vavuum pump 8
It is evacuated, and unnecessary resin is exported to resin receiver 3.The negative pressure of vavuum pump is preferably 0.1
MPa。
Such resin receiver 3 is set, on the one hand, unnecessary resin can be reclaimed, to circulate again
Utilize, on the other hand, prevent resin from flowing into vavuum pump, cause vacuum pump failure.
Step 500：Glass layer of cloth is heated, solidifies it.
Electric blanket is covered in glass layer of cloth, so as to be heated to glass layer of cloth, solidifies it.Also may be used
Glass layer of cloth is heated with shot-light at the top of use, solidifies it.The temperature of heating is preferably 60 DEG C
-70℃。
Step 600：Vacuum bag film successively on removing glass layer of cloth, flow-guiding screen, release cloth.
Although the foregoing describing the embodiment of the present invention, those skilled in the art should manage
Solution, this is merely illustrative of, and protection scope of the present invention is defined by the appended claims.Ability
The technical staff in domain, can be to these embodiments on the premise of the principle and essence without departing substantially from the present invention
Various changes or modifications are made, but these changes and modification each fall within protection scope of the present invention.
