Description
Technical field
The present invention relates to a kind of battery air tightness pick-up unit, relate in particular to a kind of apparatus for automatically detecting battery air tightness.
Background technology
In the manufacturing process of battery, need to carry out impermeability and detect, avoid causing phenomenons such as battery electrolyte leakage because of failure welding to the battery after the welding.Existing air-tightness detection method mostly is water tank type manual detection method, adopt in the liquid injection hole on the gas port insertion battery cover board that manually will be connected with finder one by one, utilize the vacuum pump decompression to form pressure differential, vacuumize the situation of emitting bubble in the container filled with water of observing, to judge the sealing property of battery soldering opening.The efficient of this impermeability detection mode is low, and detection sensitivity is low, and the operation easier of gas port being inserted liquid injection hole is big, is difficult to satisfy the demand of industrial mass production, and may cause the judgement to erroneous results because of manually-operated is improper.
Summary of the invention
The object of the present invention is to provide a kind of apparatus for automatically detecting battery air tightness, this device detection efficiency height, simple to operate, can accurately judge whether gas leakage.
The present invention is achieved like this, apparatus for automatically detecting battery air tightness, it comprises frame, battery clamp, detecting device, worktable, push pedal, tank, air extractor and controller, described frame is L shaped, battery clamp is installed on the frame underframe, the battery clamp bottom is provided with stroke cylinder, and battery clamp is made up of adjustable screw and positioning fixture; The frame bottom outside is provided with push pedal and advances battery, and push pedal connects the twin-tub cylinder; Upper rack is provided with adjustable cylinder, and it is connected with sliding bar, and worktable is connected on the sliding bar, and a plurality of detecting devices are installed on the worktable, and detecting device is made up of suction nozzle and sucker; Be connected with the wireway that links to each other with detecting device and the conduit of bleeding in the tank, corresponding demonstration is arranged on tank and the battery clamp.
In the present invention, positioning fixture is made up of fixed part and movable block.
In the present invention, the surface level of suction nozzle is higher than the surface level of sucker.
In the present invention, the quantity of detecting device is 1-40.
When said structure uses, at first the suitable batteries size is adjusted in the positioning fixture gap of battery clamp by adjustable screw, adjust the position of detecting device then by adjustable cylinder, being transferred to the sucker that makes detecting device can be adsorbed on the block, and liquid injection hole is sealed fully.Step on foot-switch, worktable moves down, and twin-tub cylinder control push pedal is pushed ahead, battery advanced put in place and fixing, device to be detected begins to vacuumize the detection impermeability after sealing the battery liquid-filling hole, at this moment with the first-class mesuring battary of another Battery pack anchor clamps, and observes the phenomenon of emitting bubble in the tank.After detection was finished, worktable was kept in the center, and push pedal is restored, step on foot-switch, will survey battery and send classification folder down, move by stroke cylinder control battery clamp then, another group mesuring battary anchor clamps are moved to below detecting device, begin another time detection again, work so repeatedly.
The advantage that the present invention has is: because apparatus for automatically detecting battery air tightness of the present invention, adopt the detecting device of band suction nozzle and sucker, make and detect effective range expansion, a plurality of detecting devices detect the battery clamp alternation that contains a plurality of positioning fixtures with at least two groups simultaneously, improve detection efficiency greatly, satisfied industrial demand, simple to operate in addition, detect prolongation observing time, testing result is accurate.

Embodiment
As shown in Figure 1, apparatus for automatically detecting battery air tightness of the present invention, it mainly comprises frame, battery clamp, detecting device 3, worktable 4, push pedal, tank 6, air extractor and controller, described frame is L shaped, battery clamp is installed on the frame underframe, the battery clamp bottom is provided with stroke cylinder, and battery clamp is made up of adjustable screw 1 and positioning fixture 2; The frame bottom outside is provided with push pedal and advances battery, and push pedal connects the twin-tub cylinder; Upper rack is provided with adjustable cylinder, and it is connected with sliding bar, and worktable 4 is connected on the sliding bar, and a plurality of detecting devices 3 are installed on the worktable 4, and detecting device 3 is made up of suction nozzle and sucker; Be connected with the wireway 5 that links to each other with detecting device 3 and the conduit of bleeding in the tank 6, corresponding demonstration is arranged on tank 6 and the battery clamp.
Described positioning fixture is made up of fixed part and movable block, the size of coming the alignment jig gap by stretching out of movable block and indentation.
The surface level of described suction nozzle is higher than the surface level of sucker, and sucker adsorbs the sealed cell liquid injection hole fully, by the suction nozzle extracting vacuum.
The quantity of described detecting device 3 is 1-40, and detecting device 3 actual quantities are 10 in the present embodiment.
During use, at first the suitable batteries size is adjusted in positioning fixture 2 gaps of battery clamp by adjustable screw 1, adjust the position of detecting device 3 then by adjustable cylinder, being transferred to the sucker that makes detecting device 3 can be adsorbed on the battery cap, and the battery liquid-filling hole is sealed fully.Battery to be checked is put into the positioning fixture 2 of automatic leak detector, after battery is put well, step on foot-switch, worktable 4 will move down automatically, sucker on the detecting device 3 presses down and is adsorbed on the battery cap simultaneously, seals the battery liquid-filling hole, and this moment, twin-tub cylinder control push pedal was with battery push-tight and fixing, open vacuum pump by inductive switch again, vacuumize and leak hunting.Leak detector is put another Battery pack anchor clamps well mesuring battary when leaking hunting, observe the tank 6 that leaks hunting simultaneously, has a large amount of bubbles in the wireway 5 during beginning in the tank 6 and emerges, and bubble slowly fades away, and until there not being bubble to emerge, illustrates that then this battery is air tight; As constantly there being bubble to emerge in the wireway in the tank when leaking hunting 65, this battery gas leakage then is described, remember the wireway that has bubble to emerge.Wait to leak hunting finish after, worktable 4 rises, push pedal is restored, step on foot-switch, will survey battery and send classification folder down, move by stroke cylinder control battery clamp then, another group mesuring battary anchor clamps are moved to below detecting device, begin another time detection, work so repeatedly.
