2.1.2 Technical requirement purpose description:
A. the P1 is mainly attached and sealed with the lens barrel, so that the interference of the P1 is required to be small and the flatness of a P1 positioning surface is required to be good;
B. Because the interference of P1 is small, when the water is washed, the impulse of the water can wash up the P1, so the interference of P2 is increased, the P1 is tightly pressed by the P2, and the P1 cannot be jacked up by the water to cause water seepage;
C. meanwhile, the requirements of the first parameter and the second parameter are met, the aim of preventing high-pressure water seepage into the lens during washing can be fulfilled, and the effect that 'P1 and the through hole of the lens barrel do not enter water' is achieved.
2.2 Improving the last lens/pressing Ring at the open end of the lens barrel
2.2.1 Dispensing the lens/pressing ring and the opening end of the lens cone, the specific requirements are as follows:
A. dispensing glue management and control, namely dispensing a whole circle of glue, not needing to be reduced in glue and breaking glue, and finally, not needing a glue hole at the shearing opening of a lens or a pressing ring;
B. the appearance monitoring and dispensing effect is adopted, when the glue is broken and a glue hole appears, the glue needs to be adjusted immediately, and the situation that the glue is full and the glue hole does not exist is required;
C. The last lens/pressing ring at the opening end of the lens cone and the inner wall of the lens cone are fully dispensed, and the requirement of 2.2.1 is met, so that the effect that water does not enter the edge of the last lens/pressing ring at the opening end of the lens cone can be realized.
2.3 By the countermeasure of 2.1 and 2.2, the lens 'P1 and the lens barrel through hole are not in water' and 'the last lens at the opening end of the lens barrel/the edge of the pressing ring is not in water'.

| P2 lens and lens barrel side contact length H2 | Average interference GY2 of lens cone and P2 lens |
| H2=0.17 | 0.008 |
Finally, the lens and the lens cone are fully sealed and dispensing is carried out;
P1 and the water inlet rate of the through hole of the lens cone are 96.7 percent;
The water inlet rate between the last lens and the lens barrel is 0%, in conclusion, the opening end of the dispensing fully-sealed lens barrel can prevent water from entering the edge of the last lens and the lens barrel, and the problem that P1 cannot enter water from the through hole of the lens barrel according to the above parameter countermeasures can not be solved.
Comparative example 2P 1 lenses, P2 lens parameters are as follows:

Finally, the lens and the lens cone are fully sealed and dispensing is carried out;
91.3 percent of water inlet rate of the through holes of the P1 and the lens cone;
the water inlet rate between the last lens and the lens barrel is 0%, in conclusion, the opening end of the dispensing fully-sealed lens barrel can prevent the last lens and the edge of the lens barrel from water inlet, and the P1 countermeasure according to the parameters cannot solve the problem that P1 and the lens barrel through hole are water inlet, but the flatness T0.0012 is slightly better than 0.003, which indicates that the flatness T of the P1 positioning surface is small.
Comparative example 3P 1 lenses, P2 lens parameters are as follows:
| p1 lens and lens barrel side contact length H1 | Average interference GY1 of lens cone and P1 lens | Flatness T |

| H2=0.17 | 0.008 |
Finally, the lens and the lens cone are fully sealed and dispensing is carried out;
p1 and 21.6% of water inlet rate of the through hole of the lens cone;
the water inlet rate between the last lens and the lens barrel is 0%, in conclusion, the opening end of the dispensing fully-sealed lens barrel can prevent the last lens from water inlet with the edge of the lens barrel, and the P1 countermeasure according to the parameters cannot solve the problem that P1 and the lens barrel through hole enter water, but the P1 interference is 0.003 better than 0.008, which indicates that the P1 interference is small and good.

| p1 lens and lens barrel side contact length H1 | Average interference GY1 of lens cone and P1 lens | Flatness T |
| H1=0.11 | 0.003 | 0.003 |
| P2 lens and lens barrel side contact length H2 | Average interference GY2 of lens cone and P2 lens |
| H2=0.17 | 0.009 |
Finally, the lens and the lens cone are fully sealed and dispensing is carried out;
P1 and the water inlet rate of the through hole of the lens cone are 10.3 percent;
The water inlet rate between the last lens and the lens barrel is 0%, in conclusion, the opening end of the dispensing fully-sealed lens barrel can prevent the last lens from water inlet with the edge of the lens barrel, and the P1 countermeasure according to the parameters cannot solve the problem that P1 and the lens barrel through hole are water inlet, but the P2 interference is 0.009 and better than 0.008, which indicates that the P2 interference is large and good.
Example 1P 1 lenses, P2 lens parameters are as follows:
| p1 lens and lens barrel side contact length H1 | Average interference GY1 of lens cone and P1 lens | Flatness T |
| H1=0.11 | 0.002 | 0.003 |
| P2 lens and lens barrel side contact length H2 | Average interference GY2 of lens cone and P2 lens |
| H2=0.17 | 0.010 |
