Row liquid filling, by the elevating control S of pressure head 6 length, and then adjusts the bore of restriction 151, so as to control filling flow
Size, realizes quantitative liquid filling, solves the problem of filling amount because of caused by the spontaneous structure problem of workpiece 8 is inaccurate.
Fluid reservoir control unit 23, which is opened, to be made, under electrical control, and cylinder pressurizes to liquid feeding fluid cylinder, and liquid passes through gap " S "
Workpiece 8 is flowed rapidly into, while the displacement transducer in cylinder monitors current displacement (i.e. current liquid volume added), setting to be approached
During pouring amount, " S " gap is gradually reduced, and the flow of liquid filling also accordingly reduces therewith, when the liquid volume added equal to setting, S gaps
It is zero, liquid is blocked completely, liquid feeding stops, the step of steel ball 16 of beating subsequently into next step is gathered.
Incorporated by reference to shown in Figure 17 and Figure 18.Step S5：The servomotor 4 drives the pressure head 6 to continue to the direction of workpiece 8
Operation, until the steel ball 16 is pressed into the workpiece 8, the steel ball 16 is interference fitted with the workpiece 8, and then is made described
Workpiece 8 is sealed.
Incorporated by reference to shown in Figure 19-Figure 21.Step S6：It is close that the servomotor 4 drives the pressure head 6 to rise to described first
At big envelope 14, the end of pressure head 6 is located between the first sealing ring 141 and internal air flue 142, and raffinate control unit 21 is opened, simultaneously
Outside over-pressure control portion 22 is opened, and outside positive air pressure is entered in pressure head passage 17 by gas channel through internal air flue 142, and then right
Filling runner produces pressure, so as to aid in filling runner to carry out raffinate.Due to the compact conformation of filling valve 1, malleation and raffinate
Junction very close to product, when flow at high speed air passes through this junction, in the presence of positive/negative-pressure, remaining liquid
All taken back.
Incorporated by reference to shown in Figure 22 and Fig. 5.Step S7：After raffinate terminates, the pressure head 6 rises, and makes into steel ball passage 161
It is connected with pressure head passage 17, the steel ball 16 enters pressure head passage 17 and offseted with the first bulb plunger 131, subsequent filling valve
1 resets.
In the present invention, headed into by the change of the position of pressure head 6 steel ball 16 of changing commanders in workpiece 8, while the obstructed reality of the position of pressure head 6
Show to the vacuumizing of workpiece 8, liquid filling and raffinate, and then realized on a station the whole filling process sealed up for safekeeping.
Simultaneously because the junction of the compact conformation of filling valve 1, malleation and raffinate is very close to product, when flow at high speed air passes through this
During junction, in the presence of positive/negative-pressure, remaining liquid is all taken back, and prevents extraction raffinate to be deposited in filling valve 1 so that true
During empty pumping vacuum, extraction raffinate enters vavuum pump, influences the life-span of vavuum pump.
Preferred embodiments of the present invention are these are only, embodiments of the present invention and protection domain is not thereby limited, it is right
For those skilled in the art, it should can appreciate that all utilization description of the invention and being equal made by diagramatic content replace
Change and obviously change resulting scheme, should be included in protection scope of the present invention.
