Description
Technical field
The utility model relates to air-tightness detection device, particularly a kind of pick-up unit of lithium battery casing crack.
Background technology
Along with the development of science and technology, being widely used of accumulator, wherein, lithium battery (as ferric phosphate lithium cell, lithium-manganese cell) is rapidly developed using its high power, long-life and security as power accumulator.Lithium battery is generally encapsulate rear use under vacuum conditions, if the housing of lithium battery has crack, the environment of lithium battery interior is then likely made to contact with atmospheric environment, the electrolytic solution of the moisture in air and lithium battery interior is reacted, thus cause lithium battery fault, even burst, affect serviceable life and the safety in utilization of lithium battery, therefore the air-leakage test of lithium battery is indispensable link during lithium battery is produced.
In actual production process, after battery slot rolling, need to check whether slot rolling rolls and split, slot rolling object is sealed after being convenient to have welded block.If slot rolling internal diameter is excessive, may leak gas after sealing.If internal diameter is too small, box hat just has crack in slot rolling position, and this battery has just been scrapped, so the internal diameter size of slot rolling is very important.Channelling machine, when slot rolling, after mixing up parameter, is processed, and needs measure internal diameter size in time or carefully check, sees and whether produces crack, but in actual mechanical process, be only difficult to detect by naked eyes.
At present, the structure of existing lithium battery air-tightness detection device patent document discloses a kind of lithium battery air-tightness detection device as notification number CN 203376120 U, comprise the bracing frame that support baseboard for placing lithium battery to be measured and support baseboard are vertically arranged, support frame as described above is provided with the support platform of vertically guiding movement, support platform is provided with test structure, described test structure comprises test block and the friction tight tested cylinder of lithium battery sealing pressing to be measured for making connection on it, described support platform is rotatably equipped with axial limiting and adjusting screw(rod) for inputting rotating force, described support platform offers threaded perforations, described threaded perforations and described adjusting screw(rod) threaded engagement.
Although effectively can be detected the impermeability of lithium battery by said apparatus, but this device in use, need repeatedly contraposition can carry out air-leakage test to lithium battery, also be provided with multidirectional detent mechanism, complex structure, thus cause the problems such as operating difficulties, adjustment is inconvenient, detection efficiency is low.
Utility model content
The utility model provides a kind of pick-up unit of lithium battery casing crack, and structure is simple, easy to use, while guarantee Detection job, improves detection efficiency.
A kind of pick-up unit of lithium battery casing crack, comprise mount pad, also comprise the detection water tank being connected with vacuum line, described mount pad is provided with several air holes, each air hole is communicated to detection water tank by gas piping, and described mount pad end face is provided with gasket seal at the edge of air hole.
When the utility model uses, detect in water tank and add water or other liquid, water covers gas piping and stretches into the part detecting water tank, then the shell nozzle after multiple slot rolling is upside down on mount pad towards air hole, shell nozzle edge is against gasket seal, detection water tank inside vacuumizes by recycling vacuum tube, now, if housing has crack at slot rolling place, then corresponding gas piping has bubble and constantly emerges, the utility model structure is simple, easy to use, can detect the housing rolling and split rapidly and accurately.
In order to increase detection accuracy, preferably, described detection water tank is provided with multiple, and each air hole correspondence connects a detection water tank.Multiple detection water tank is set and tests corresponding lithium battery respectively, the problem judged by accident not easily occurs.
For the ease of manufacturing and using, preferably, each water tank that detects is interconnected, and shares a vacuum line.Each detection water tank can be vacuumized by same vacuum tube.
For the ease of observing, preferably, the manufactured materials of described detection water tank adopts transparent material.Transparent material can be glass or thoroughly close plastics.
Conveniently use, further preferably, every root gas piping is all provided with ventilation switch.When the air hole that gas piping is corresponding does not have holder housing, close corresponding ventilation switch, be convenient to the battery testing other air holes, prevent interference, improve practicality.
In order to improve sealing, preferably, described gasket seal is provided with the ring groove coordinated with shell nozzle edge.
The beneficial effects of the utility model:
The pick-up unit in lithium battery casing crack of the present utility model, can the fast and effeciently multiple lithium battery case weight of one-time detection, simple to operate, easy to use, effectively improve detection efficiency, and device structure is simple, low cost of manufacture.
