Embodiment
As shown in figure 1, the liquid-level detecting method of the lens monomer cast of the present invention-to the method for penetrating, comprise the following steps：
Step 1, support meanss will be fixed on for the mould 1 for loading lens monomer；Mould 1 uses glass material system
Into being provided with sprue gate 1a on mould 1, sprue gate 1a is sealed using adhesive tape 2.The support meanss include bearing 3, to mould
Have adsorbing mechanism 4, the sensor frame 5 positioned, bearing 3 is L-shaped, and adsorbing mechanism 4 is arranged on bearing 3；Bearing 3 is provided with
Hole, the hole is passed through for one end of adsorbing mechanism 4, and adsorbing mechanism 4 includes hollow shaft, flexible disk and negative pressure mechanism, hollow shaft
One end is connected through flexible disk behind the hole set on bearing 3, and flexible disk will not block the airflow orifice of hollow shaft, hollow shaft it is another
End is connected with negative pressure mechanism, mould 1 is fitted with flexible disk, flexible disk is tapered, is formed between mould 1 and flexible disk
One cavity, flexible disk is formed to the cavity after sealed effect, unlatching negative pressure mechanism, the suction function that negative pressure mechanism is produced
Power is aspirated the cavity between mould and flexible disk, is adsorbed so that mould is adsorbed mechanism 4, suction is supported on securely
On random structure 4.One end of sensor frame 5 is arranged on bearing 3, and the other end of sensor frame 5 is provided with to be passed through for opposite type sensor
Pilot hole.Sensor frame is movably connected on bearing.Further, in addition to screw rod (not shown), on the bearing 3
Provided with groove, the side wall of groove is provided with slide rail, and the both sides of the sensor frame 5 are provided with chute, the chute of sensor frame 5 with it is described
Slide rail coordinates, and the hole that sensor frame 5 is provided with hole, one end and sensor frame of the screw rod is installed in rotation on after coordinating
On bearing, screw rod and sensor frame one screw body of formation rotate screw rod, can make sensor frame 5 along in the axial direction of screw rod
Lower movement, can so be adjusted to the spacing between sensor frame 5 and mould 1, after various sizes of mould is changed, pass through
The spacing between sensor frame 5 and mould 1 is adjusted, the opposite type sensor being arranged on sensor frame 5 can be to the mould after replacing
Interior lens monomer is detected.
Step 2, opposite type sensor is symmetrically fixed on sensor stand, opposite type sensor probe is hanging in the mould
Sprue gate both sides, and opposite type sensor probe and sprue gate vertical direction distance are 0.1-0.5mm；
Opposite type sensor 6 because pilot hole is through hole, and is set through the pilot hole on sensor frame 5 in opposite type sensor 6
There are 2 fixing nuts, therefore, after opposite type sensor 6 passes through pilot hole, opposite type sensor 6 is relative to the position of sensor frame 5
Constant, for size identical mould 1, it is only necessary to which the position of sensor frame 5 is had good positioning, i.e. the positioning causes
The distance between probe and sprue gate 1a apertures vertical direction of opposite type sensor 6 are 0.1-0.5mm.
Step 3, when injecting lens monomer into mould, judge to be injected into die cavity by opposite type sensor signal intensity
Whether lens monomer fills.
In step 3, when lens monomer does not arrive sprue gate, opposite type sensor can't detect signal intensity, work as lens monomer
During to sprue gate, opposite type sensor is the prompting of detectable signal.
Opposite type sensor can't detect signal intensity, and when lens monomer is to sprue gate, opposite type sensor is that can detect
The prompting of signal.
For example, when lens monomer is not with to sprue gate 1a, signal intensity, explanation are not detected in opposite type sensor 6
Not enough, when lens monomer is to sprue gate 1a, opposite type sensor can be examined the amount for the lens monomer being injected into the cavity of mould 1
The prompting of signal is measured, illustrates that the amount for the lens monomer being injected into the cavity of mould 1 meets the requirements.So, as long as to penetrating sensing
Device is the prompting of detectable signal, you can whether the amount for obtaining cast meets corresponding requirement.
