Which position leak, therefore cause water-proof wire bundle manufacturing process cumbersome.
Invention content
Goal of the invention：In order to overcome the deficiencies in the prior art, the present invention provides one kind can detect waterproof automatically
Water-proof wire bundle automatic testing method.
Technical solution：To achieve the above object, the technical solution adopted by the present invention is：
A kind of automatic testing method of water-proof wire bundle, includes the following steps：
Step 1, water-proof wire bundle is mounted on the harness installing port of closed detection babinet；
Step 2, water will be dyed from being pumped into pond in closed detection case body by starting dyeing water pump；
Step 3, start the air in the closed detection case body of air pumping, and close air pump, pressed at this time by outside
Force snesor detects the pressure of the air pipeline of air pump at this time, as initial gas pressure；
Step 4, after waiting a period of times, the atmospheric pressure of closed detection babinet is detected by internal pressure sensor, as inspection
Survey atmospheric pressure；
Step 5, compare initial gas pressure and detection atmospheric pressure illustrates harness gas leakage, waterproof effect if there is pressure difference
If difference illustrates harness good water-proof effect without pressure difference.
Preferably：Dyeing water in closed detection case body is higher than harness installing port top.
Further：In step 5, if detecting, harness is non-watertight, starts air pump and adds to the inflation of closed detection babinet
Pressure, is then shut off air pump, the pressure of the air pipeline of air pump at this time is detected by external pressure sensor at this time, as anti-
Detect atmospheric pressure；After equal a period of times, the atmospheric pressure of closed detection babinet is detected by internal pressure sensor, is surveyed as reverse-examination
Atmospheric pressure；Compare reverse-examination survey atmospheric pressure and reverse-examination surveys atmospheric pressure and illustrates that harness is non-watertight if there is pressure difference, if without pressure
Difference then illustrates harness good water-proof effect.
Preferably：If it is detected that harness is non-watertight, whether there is dyeing water on harness by observing, by the position for dyeing water
It sets, judges non-water-tight position, then harness related process is improved, prevent the water leakage situation of position here.
The present invention compared with prior art, has the advantages that：
The present invention can automatically detect the water proof case of harness, while can judge leaking area according to water leakage situation, into
And harness manufacturing process is improved by leaking area.
Description of the drawings
Fig. 1 is structural schematic diagram.
Specific implementation mode
In the following with reference to the drawings and specific embodiments, the present invention is furture elucidated, it should be understood that these examples are merely to illustrate this
It invents rather than limits the scope of the invention, after having read the present invention, those skilled in the art are various to the present invention's
The modification of equivalent form falls within the application range as defined in the appended claims.
A kind of automatic testing method of water-proof wire bundle, as shown in Figure 1, including the following steps：
