As shown in the figure, a kind of rubber gloves leakage detection apparatus and detection method, the transparent sink 6 including containing liquid B 5, There is a lifting motor 71 outside sink 6, the lifting motor 71 is fixed on by support base 72 on 6 outer wall of sink, lifting motor 71 Elevating screw 73 on output shaft is installed, the guiding axis 74 parallel with elevating screw 73 on support base 72 is installed, is being lifted Support arm 75 is installed, the support arm 75 can be realized up and down with the rotating of elevating screw 73 on leading screw 73 and guiding axis 74 Mobile, 75 end of support arm is equipped with anchor tip 1, gas-guide tube 11, catheter is provided through on the anchor tip 1 12 and vacuum tube 13, correspondence is equipped with intake valve 111, inlet valve respectively on the gas-guide tube 11, catheter 12 and vacuum tube 13 121 and vacuum valve 131, the intake valve 111, inlet valve 121 and vacuum valve 131 respectively with air compressor machine 112,122 and of reservoir Vacuum pump 132 is connected, on the gas-guide tube 11 and vacuum tube 13 between the intake valve 111 and vacuum valve 131 and anchor tip 1 It is installed respectively due to the detection pressure sensor 113 of air pressure and vacuum transducer 133, liquid A 4 is contained in the reservoir 122, An anchor ear 2 is nested in 1 outside of anchor tip, 3 opening of gloves is set on anchor tip 1, and anchor ear 2 is nested with to be open in gloves 3 Place, places the sensor probe 82 of chromaticity detector 81 in 6 liquid B 5 of sink, and the chromaticity detector 81 is mounted on controller On 8, the intake valve 111, air compressor machine 112, pressure sensor 113, inlet valve 121, vacuum valve 131, vacuum pump 132, vacuum Sensor 133, lifting motor 71 and chromaticity detector 81 are electrical connected respectively with controller 8.
Further, in order to which preferably convenient for observation, the liquid A 4 and 5 prioritizing selection of liquid B are colourless transparent liquid, It is reacted after meeting by visually can also be observed that apparent color change.
Further, the liquid A 4 and liquid B 5 are respectively sodium acid carbonate and phenolphthalein solution.
Further, in the gloves 3 liquid A 4 liquid level higher than liquid B 5 in sink 6 liquid level 3~ 5cm。
Further, for a better understanding of the present invention, the detection method of the present invention is additionally provided, is included the following steps:
Controller 8 controls lifting motor 71 to rotate forward, and elevating screw 73 is driven to rotate forward, and makes the support being located on elevating screw 73 Arm 75 moves up, and so as to which anchor tip 1 be driven to be moved upwards up to the top of elevating screw 73, subsequent lifting motor 71 stops work Make.
The liquid B 5 of gloves height can not had by being packed into sink 6, while by the sensor probe 82 of chromaticity detector 81 It is placed in sink 6.
3 opening of gloves is nested in 1 outside of anchor tip, gloves 3 are fixed on fixation with the elastic anchor ear 2 of rubber connects On first 1.
Controller 8 controls charge valve 111 and air compressor machine 112 to open, and clean compression is passed through into gloves 3 by gas-guide tube 11 Air, when the detection of pressure sensor 113 reaches pressure set points, controller 8 controls intake valve 111 and air compressor machine 112 to close, Whether observation gloves 3 have apparent leakage, and situation is serious to be ruptured.
Controller 8 controls vacuum valve 131 and vacuum pump 132 to open, and the air in the gloves 3 by above-mentioned detection is taken out Go out, when vacuum transducer 132 detects pressure set points, controller 8 controls vacuum valve 131 and vacuum pump 132 to close.
Controller opens inlet valve 121, and the liquid A 4 in reservoir 122 is injected by catheter 12 in gloves 3, keeps For liquid A 4 full of inside gloves 3, controller 8 controls charge valve 111 and air compressor machine 112 to be again turned on, by gas-guide tube 11 to hand Clean compressed air is passed through in set 3, when the detection of pressure sensor 113 reaches pressure set points, controller 8 controls intake valve 111 and air compressor machine 112 close, maintain 3 internal pressure of gloves it is powerful in outside pressure, and hang stand setting time value, observe Liquid A 4 is whether there is outside gloves 3 to ooze out.
Controller 8 controls lifting motor 71 to rotate forward, and the support arm 75 being located on elevating screw 73 is driven to move downward, makes hand Set 3 is immersed in liquid B 5, when the liquid level of liquid A 4 in gloves 3 is higher than 3~5cm of liquid level of liquid B 5, control Device 8 controls lifting motor 71 to be stopped.
At this point, since the pressure in gloves 3 is more than outside pressure, if gloves 3 have tiny leaks point, liquid A 4 is through letting out Leak source leaks out, and meets with liquid B 5, generates apparent color change, while the sensor probe 82 in sink 6 detects Colourity changes, and sends alarm signal by chromaticity detector 81, shows that gloves 3 are unqualified, if gloves 3 do not have leakage point, Chromaticity detector 81 does not send alarm signal, then shows that gloves 3 are qualified.
