Abstract
The invention discloses an airtightness test fixture. The airtightness test fixture comprises a fixture frame, a control panel arranged in the fixture frame, test seats installed on the upper surface of the fixture frame, and air pressure monitors for detecting air pressure change inside an electronic component to be tested, wherein the test seats are connected with air inlet pipes and have air inlets communicating with the electronic component to be tested formed therein, the air pressure monitors are electrically connected with the control panel, and the fixture frame is also provided with displays and indicating lamps which are controlled by the air pressure monitors. The airtightness test fixture has the following advantages: a conventional bubble detection method in the prior art is replaced, and under the condition that external air pressure is not changed, the airtightness of the electronic component is tested through detecting the air pressure change inside the electronic component; and whether the sealing performance of the electronic component is qualified can also be displayed through the indicating lamps, and therefore, the airtightness test fixture has a good industrial popularization value and prospect.
Description
Technical field
The present invention relates to a kind of tool, be specifically related to a kind of air tightness test tool, belong to field of mechanical technique.
Background technology
Electronic devices and components must have good sealing, thus guarantee water proof and dust proof in use procedure, to ensure every electric property of electronic devices and components.In prior art, be generally that is: the hand-held electronic devices and components to be measured of special messenger are immersed in the water by electronic devices and components immersion being detected its impermeability, visual have bubble-free to produce, if alveolate words, illustrate poor sealing, be NG product, bubble-free is then OK product.There is many defects in such detection, (1), detected after, need use air gun water is blown off, on average about need 20s, waste time and energy; (2), as fruit product gas leakage, still bubble is less, be then not easy to find out, and very easily because subjective factor causes erroneous judgement; (3), electronic product inside generally have the components and parts such as lubricating oil, LED, resistance, coil, be soaked in water and will impact its reliability and serviceable life.In view of the foregoing, in the urgent need to one instead air tightness test tool.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of air tightness test tool to electronic devices and components not damaged, accuracy of judgement.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
Air tightness test tool, comprise: tool framework, the control panel be arranged in tool framework, be installed on tool frame upper surface test bench, for detect electronic devices and components air pressure inside to be measured change pressure monitor, described test bench connects a draft tube and is formed with the air intake opening be communicated with electronic devices and components to be measured, described pressure monitor is electrically connected with control panel, described tool framework is also provided with the display and pilot lamp that control by pressure monitor.
Aforementioned test bench is at least two, and described pressure monitor and test bench one_to_one corresponding are arranged.
Preferably, the pilot lamp that aforementioned each pressure monitor controls is at least two, comprises red light and green light.
Further, aforementioned test bench inside is hollow structure, and draft tube is stretched out and is connected to the side of base in tool framework.
Preferably, aforementioned draft tube is provided with an air intake valve.
Again further, also have a transition face be obliquely installed between the end face of aforementioned tool framework and front, described display and pilot lamp are all arranged on transition face.
Usefulness of the present invention is: air tightness test tool of the present invention, instead of manual bubble detection method traditional in prior art, when external pressure is constant, tested the sealing of electronic devices and components by the situation of change of detected electrons element internal air pressure; And whether show the sealing of electronic devices and components intuitively by pilot lamp qualified, there is good commercial introduction and be worth and prospect.
Accompanying drawing explanation
Fig. 1 is the perspective view of a preferred embodiment of air tightness test tool of the present invention.
The implication of Reference numeral in figure: 1, tool framework, 11, end face, 12, front, 13, transition face, 2, test bench, 21, air intake opening, 3, draft tube, 4, display, 5, pilot lamp, 6, air intake valve.
Embodiment
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the present invention.
Its structure of air tightness test tool of the present invention is see Fig. 1, comprise: tool framework 1, be arranged at the control panel (not shown) in tool framework 1, be installed on the test bench 2 of tool framework 1 upper surface, pressure monitor for detecting electronic devices and components air pressure inside to be measured change (is positioned at tool framework 1, therefore not shown), wherein, test bench 2 connects a draft tube 3 and is formed with the air intake opening 21 be communicated with electronic devices and components to be measured, pressure monitor is electrically connected with control panel, tool framework 1 is also provided with the display 4 and pilot lamp 5 that control by pressure monitor.Test philosophy is: when external pressure is constant, the air pressure change of test electronic devices and components inside, if air pressure change exceedes setting value within a certain period of time, then represents that impermeability is defective.In test process, electronic devices and components to be installed on test bench 2 and to dock with air intake opening 21, so just by draft tube 3 to " input " air pressure in electronic devices and components, then, by the air pressure change of pressure monitor test electronic devices and components inside, test result is presented at intuitively on display 4, can also be whether qualified by the impermeability of the direct teaching process person product of pilot lamp 5.
Preferably, test bench 2 is at least two, and pressure monitor and test bench 2 one_to_one corresponding are arranged, and can realize multiple electronic devices and components like this and detect simultaneously, improve testing efficiency.
We said above, pilot lamp 5 is used to inform that whether products air tightness is qualified intuitively, therefore, the pilot lamp 5 that each pressure monitor controls is at least two, comprise red light and green light, wherein, it is underproof NG product that red light is used to indicate product, green light then represents that product is qualified OK product, improves the operability of tool.
As a kind of concrete structure, in order to input air pressure in electronic devices and components to be measured, be hollow structure by test bench 2 indoor design, as shown in Figure 1, draft tube 3 is stretched out and is connected to the side of base in tool framework 1, like this, air intake opening 21 is positioned at the top of draft tube 3 and base junction and has certain distance between the two, the speed that gas enters in electronic devices and components will more evenly relax, little to the impulsive force of electronic devices and components inside, avoids damaging internal components.
Conveniently control air inlet, draft tube 3 is also provided with an air intake valve 6.
As a modification of the present invention, in order to improve the convenience of operator, between the end face 11 and front 12 of tool framework 1, also have a transition face be obliquely installed 13, display 4 and pilot lamp 5 are all arranged on transition face 13, more meet the requirement of ergonomics.
More than show and describe ultimate principle of the present invention, principal character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the present invention in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection scope of the present invention.
