Abstract
Loculus body leak testing device includes: the vacuum generator, pressure sensor and the vacuum chuck that mutually support, wherein, vacuum chuck holds and waits to detect the product and reserve the inspection hole, and vacuum generator passes through pressure sensor and connects vacuum chuck, pressure sensor and vacuum chuck between be equipped with vacuum filter, the utility model discloses the product cavity need have a hole to be used for the test, from the aperture with the evacuation of product cavity, the vacuum value of looking over pressure sensor after the evacuation, when the null value of taking seriously does not reach the setting value then the product for leaking, efficiency of software testing depends on product cavity size and vacuum generator flow, belong to low -cost test scheme.
Description
Technical field:
This utility model relates to a kind of gas leak detection apparatus, especially relevant with one little cavity leakage tester.
Background technology:
On automatic production line, it is often necessary to the cavity sealing of some product is detected, reject product leakage, it is ensured that the qualification rate of finished product, existing detection equipment is generally bulky, and cost is significantly high, and detection efficiency is very low.
Utility model content:
This utility model purpose is in that to solve the problems referred to above, it is provided that a kind of volume is little, the little cavity leakage tester that Detection accuracy is high and cost is low.
For reaching above-mentioned purpose, this utility model adopts the following technical scheme that
Little cavity leakage tester, including: vacuum generator, pressure transducer and the vacuum cup cooperated；Wherein, vacuum cup holds product to be detected reserved detection hole, and vacuum generator connects vacuum cup by pressure transducer.
Further, it is provided with vacuum filter between described pressure transducer and vacuum cup.
Adopting technique scheme, this utility model product cavity need to have a hole for testing；From aperture by product cavity evacuation；Checking the vacuum values of pressure transducer after evacuation, when vacuum values does not reach setting value, then product is leakage；Testing efficiency depends on product cavity size and vacuum generator flow；Belonging to the testing scheme of low cost, test beat is less than 5S/PCS.
Accompanying drawing illustrates:
With accompanying drawing, this utility model is described in detail below:
Fig. 1 is this utility model overall structure schematic diagram.
Detailed description of the invention:
Below in conjunction with drawings and Examples, this utility model is described in detail:
Shown in Fig. 1, for embodiment of the present utility model, little cavity leakage tester, including: vacuum generator 1, pressure transducer 2 and the vacuum cup 3 cooperated；Wherein, vacuum cup 3 holds product to be detected reserved detection hole, and vacuum generator 1 connects vacuum cup 3 by pressure transducer 2.It is provided with vacuum filter 4 between described pressure transducer 2 and vacuum cup 3.
During work, vacuum generator is used for producing negative pressure；Pressure transducer is used for detecting pipeline vacuum value；
Suck dust when vacuum filter is for the work of filtering vacuum sucker, protect vacuum unit；Vacuum cup 3 is for docking with product, it is ensured that Butt sealing；Vacuum generator is connected with pressure transducer, vacuum filter by three-way interface, and vacuum filter is connected with vacuum cup, and vacuum cup is connected with product.
Described above illustrate and describes preferred embodiment of the present utility model, as previously mentioned, it is to be understood that this utility model is not limited to form disclosed herein, it is not to be taken as the eliminating to other embodiments, and can be used for other combinations various, amendment and environment, and in utility model contemplated scope described herein, can be modified by the technology of above-mentioned instruction or association area or knowledge.And the change that those skilled in the art carry out and change are without departing from spirit and scope of the present utility model, then all should in the protection domain of this utility model claims.
