Description

The car headlamp impermeability detects machine
Technical field
The utility model relates to the impermeability detection range, is specifically related to detect machine for detection of the bubble-tight car headlamp impermeability of automobile lamp.
Background technology
General impermeability detection all is to adopt differential pressure method to detect in the prior art, namely pass through behind standard items and the test article while injection pressure air, stop inflation, measure because leakage causes pressure inside by high-sensitive differential pressure pick-up and change, be i.e. differential pressure value between test article and the standard items.Judge according to differential pressure value whether products air tightness is qualified.Though its accuracy of detection is than higher, efficient is lower, is not suitable for large batch of full inspection on the production line, can only be used for doing sampling observation, and expensive, complicated operation, maintenance inconvenience, also higher to operator's requirement.For these reasons, the task of top priority need be developed a novel airtight detection machine and replaced.
Summary of the invention
Technical problem to be solved in the utility model is to provide the car headlamp impermeability to detect machine, and is reasonable in design, simple in structure, and processing ease is easy to maintenance, the reliability height, and economic real being suitable for requires lowly to the operator, be fit to the detection of typical products in mass production.
For solving above-mentioned existing technical matters, the utility model adopts following scheme: the car headlamp impermeability detects machine, a two-position two-way solenoid valve that comprises vacuum pump, is connected with described vacuum pump, the packoff for placement car light product that is connected by vacuum line with two mouthfuls of bottle,suctions of described two-position two-way solenoid valve connection, with described two mouthfuls of bottle,suctions.
As preferably, described vacuum line is provided with two-position two-way solenoid valve No. two.By adopting this set, when outage, can constitute closed pipeline with car light product, packoff, vacuum line, electric contact vacuum meter, two-position two-way solenoid valve and two mouthfuls of bottle,suctions.
As preferably, also be provided with the electric contact vacuum meter on the described vacuum line.By adopting this set, can make things convenient for and read internal pressure pressure at any time.
As preferably, described packoff comprises sealing holder mould, be located at first O-ring seal on the holder die orifice of sealing holder mould.By adopting this set, can be used for impermeability between detection of reflected device and the lens, the holder die orifice of sealing holder mould is provided with first O-ring seal, has strengthened the sealing effectiveness of sealing holder mould.
As preferably, described packoff comprises seal box, is located at second O-ring seal on the seal box.By adopting this set, can be to carrying out the impermeability detection in reverberator underseal hole through the qualified car light product of reverberator and lens sealing after testing, and be provided with second O-ring seal, good sealing effect.
Beneficial effect:
The utility model adopts technique scheme to provide the car headlamp impermeability to detect machine, has remedied the deficiencies in the prior art, and is reasonable in design, simple in structure, processing ease, easy to maintenance, the reliability height, economic and practical, the operator is required low, be fit to the typical products in mass production check.

Structural representation when Fig. 1 adopts sealing holder mould to arrange for the utility model packoff;
Structural representation when Fig. 2 adopts seal box to arrange for the utility model packoff.
Embodiment
Shown in Fig. 1-2, the car headlamp impermeability detects machine, comprises vacuum pump 1, a two-position two-way solenoid valve 2 that is connected with described vacuum pump 1, the packoff for placement car light product that is connected by vacuum line 4 with two mouthfuls of bottle,suctions 3 of a described two-position two-way solenoid valve 2 connections, with described two mouthfuls of bottle,suctions 3.Described vacuum line 4 is provided with two-position two-way solenoid valve 5 No. two.Also be provided with electric contact vacuum meter 6 on the described vacuum line 4.Described packoff comprises sealing holder mould 7, is located at first O-ring seal 71 on the holder die orifice that seals holder mould 7.Described packoff comprises seal box 8, is located at second O-ring seal 81 on the seal box 8.
During real work, with vacuum pump 1, a two-position two-way solenoid valve 2, two mouthfuls of bottle,suctions 3, vacuum line 4 is connected respectively in turn with packoff, on vacuum line 4, connect No. two two-position two-way solenoid valves 5 and electric contact vacuum meter 6 more respectively, when being used between detection of reflected device and the lens impermeability, adopt half airtight detection, packoff comprises sealing holder mould 7 and is located at first O-ring seal 71 that seals on the holder die orifice that holds in the palm mould 7, be ready to the car light product that to test, they are successively placed on the sealing holder mould 7, holder die orifice portion is provided with first O-ring seal 71, a two-position two-way solenoid valve 2 and No. two two-position two-way solenoid valves 5 are opened respectively, detected car light product internal gas filters bottle 3 by two mouthfuls and extracts out, electric contact vacuum meter 6 shows its force value, when air pressure drop to-two-position two-way solenoid valve 2 outages are closed during 0.05MPA, this moment is by two mouthfuls of bottle,suctions 3, No. two two-position two-way solenoid valves 5, electric contact vacuum meter 6, vacuum line 4, sealing holder mould 7 and detected car light product are formed closed pipeline.When sealing place had leakage, because outside pressure is greater than pressure in the bottle, gas is inevitable to be flowed into two mouthfuls through vacuum line 4 and filter bottle 3, can judge product leakage when bubble occurring.Emerge as no bubble in 15 seconds, can judge that then product is qualified together; Seal the impermeability detection that qualified car light product can carry out reverberator underseal hole through detection of reflected device and lens, adopt complete airtight detection, packoff comprises seal box 8 and second O-ring seal 81 that is arranged on the seal box 8, be ready to the car light product that to test, they are successively placed in the seal box 8, be provided with second O-ring seal 81 in the seal box 8, a two-position two-way solenoid valve 2 and No. two two-position two-way solenoid valves 5 are opened respectively, detected car light product internal gas filters bottle 3 by two mouthfuls and extracts out, electric contact vacuum meter 6 shows its force value, when air pressure drop to-0.05MPA after, no bubble is emerged in 15 seconds, judges that then full impermeability detects to qualified.The method is simple to operate, directly perceived.The utility model adopts the method that directly vacuumizes, and when carrying out vacuum detecting with the detection of negative pressure method, because of outside pressure Da Yu product internal pressure, so product is directly to be attracted to above the frock, do not need external force to fix, and pressure shows and also can adopt numeral to show that vacuum meter replaces, and makes the total system precision higher more reliable.Reasonable in design, simple in structure, processing ease, easy to maintenance, the reliability height, economic and practical, the operator is required low, be fit to the typical products in mass production check.
Specific embodiment described herein only is that the utility model spirit is illustrated, the utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
