Abstract
The invention provides an improved method for a high-pressure resistance test process of an endoscope. The method comprises the following steps that 1) after a light guide post and lens sealing glass are arranged on an upper casing of a lens, the reinforcement is carried out on UV (ultraviolet) glue of the upper casing of the lens, the light guide post and the lens sealing glass; 2) before the glue is filled inside the endoscope, beautiful grain additive tapes are pasted on a glue outlet hole part; and 3) when an insulation rubber ring is pasted with a soft stem lower casing of the casing, spot gluing is carried out at a generated gap part. The final qualification rate of the process endoscope after the high-pressure resistance test is obviously improved.
Description
Technical field
The present invention relates to the modification method of the high pressure resistant test technology of a kind of endoscope.
Background technology
There is following defect in current industrial endoscope: 1, camera lens seal glass punctures in high pressure resistant test; 2, light-guiding pillar glass sheet punctures; 3, encapsulating plastic hole punctures; 4, camera lens soft stalk lower casing place punctures.Its main cause is that carrying out a glue after camera lens seal glass and light-guiding pillar are installed is single job.And encapsulating plastic hole punctures, by analysis for institute's non-filling of encapsulating water in endoscope head divides, Chu You gap, plastic hole: 1. in encapsulating process, does not discharge the air in introscope; 2. when air is discharged, glue is taken out of, occur the glue that overflows; 3. occur that excessive glue is then judged to be that encapsulating is abundant, cause gap to occur.And to puncture be because of this glue position at camera lens soft stalk lower casing place, put at lower casing place, only play fixation, can not improve the high-voltage resistance capability of product, the gap location that high pressure can exist from lower casing and electro-insulating rubber circle punctures.
Summary of the invention
Endoscope of the present invention carries out Hi-pot test and has carried out technologic improvement, with avoid camera lens seal glass and light-guiding pillar glass sheet breakdown, and then to make in endoscope head encapsulating abundant by improving encapsulating gimmick, moreover solve the breakdown problem in plastic hole or camera lens soft stalk lower casing place by the some glue position of the soft stalk lower casing of improvement and electro-insulating rubber circle joint place.
The technical scheme adopted is as described below:
The high pressure resistant test technology modification method of a kind of endoscope, comprises the following steps:
After light-guiding pillar and camera lens seal glass sheet are installed to camera lens upper casing by some glue mode, respectively the reinforcement of UV glue is carried out to camera lens seal glass sheet and light-guiding pillar.
When carrying out the reinforcement of UV glue to camera lens seal glass sheet, the surrounding point one along camera lens seal glass sheet encloses UV glue.
When carrying out the reinforcement of UV glue to light-guiding pillar, the gap location point UV glue of fitting at camera lens upper casing and light-guiding pillar carries out reinforcement.
Further, before encapsulating is carried out in endoscope inside, stick U.S. line adhesive plaster at plastic hole place.
Further, a glue is carried out in the gap produced when electro-insulating rubber circle and the soft stalk lower casing of camera lens are fitted.
By the method for the invention, by increasing UV glue reinforcement process, improve the high-voltage resistance capability of camera lens seal glass and upper casing and light-guiding pillar and upper casing joint; Improve encapsulating gimmick, encapsulating in endoscope head can be made abundant; Improving the some glue position of soft stalk lower casing and electro-insulating rubber circle joint place, while can being adhesively fixed meeting lower casing and electro-insulating rubber circle, improving the high-voltage resistance capability of this part of endoscope.

Embodiment
Fig. 1 is the camera lens part subassembly schematic diagram of the embodiment that the present invention relates to, and as shown in Figure 1, camera lens part subassembly to be modified comprises electro-insulating rubber circle 1, the soft stalk lower casing 2 of camera lens, glue feeding opening 3, plastic hole 4, light-guiding pillar 5, camera lens seal glass 6 and camera lens upper casing 7.
Fig. 2 is original flow of installation frame diagram of current camera lens seal glass 6 and light-guiding pillar 5, after camera lens seal glass 6 and light-guiding pillar 5 glue, is installed on camera lens upper casing 7, carries out excessive glue cleaning, then toast glue curing, carries out finished product cleaning inspection.Fig. 3 is the flow of installation frame diagram of camera lens seal glass 6 and light-guiding pillar 5 in the embodiment of the present invention, after light-guiding pillar 5 and camera lens seal glass 6 are arranged on camera lens upper casing 7, be after excessive glue cleans and toasts glue curing, respectively reinforcement carried out to the UV glue of camera lens seal glass 6 and light-guiding pillar 5 and camera lens upper casing 7.
Fig. 4 is the schematic diagram of UV glue 8 glue positions of camera lens seal glass 6 in embodiment, and Fig. 5 is the enlarged diagram of Fig. 4 point glue position, and as shown in Figure 4 and Figure 5, UV glue 8 reinforcement of camera lens seal glass 6 encloses UV glue 8 along camera lens seal glass 6 surrounding point one.
Fig. 6 is the schematic diagram of light-guiding pillar 5 glue positions in embodiment, UV glue 8 reinforcement of light-guiding pillar 5, is to fit the reinforcement of gap location point UV glue 8 at camera lens upper casing 7 and light-guiding pillar 5, namely in the groove at light-guiding pillar 5 back, puts glue.
By mending glue to camera lens seal glass 6 and light-guiding pillar 5, UV glue buffer strip together with just can increasing with camera lens seal glass 6 and between high pressure with light-guiding pillar 5 at high pressure, this buffer strip can alleviate camera lens seal glass 6 and the impacting with high pressure suffered by light-guiding pillar 5, improves the high voltage bearing ability of endoscope.
Producing the first schematic diagram of clearance when Fig. 7 is current encapsulating, is in encapsulating process, is not discharged by the air in introscope.Wherein clearance 9 also exists in AB glue 10, does not discharge.Produce the second schematic diagram of clearance when Fig. 8 is current encapsulating, when air is discharged, glue is taken out of, occurred excessive glue 11, but in fact also have air not discharge.Produce the 3rd schematic diagram of clearance when Fig. 9 is current encapsulating, occur that excessive glue is then judged to be that encapsulating is abundant, thus cause gap to occur.
Schematic diagram when Figure 10 is encapsulating in the embodiment of the present invention, before encapsulating is carried out in endoscope inside, sticks U.S. line adhesive plaster 12 at plastic hole 4 place.AB glue 10, just as a sieve, intercepts at endoscope inner by U.S. line adhesive plaster 12, is discharged by internal gas, and when guaranteeing encapsulating, endoscope head encapsulating is abundant.
Figure 11 is the some glue position of the soft stalk lower casing 2 of current camera lens and electro-insulating rubber circle 1 joint place, and this glue position, only plays fixation, can not improve the high-voltage resistance capability of product, and high pressure can puncture from gap location.
