The battery airtightness water-detection device is simple in structure, and easy to operate, can detect air leakage state of a heat sealing cover of the battery in only three seconds, and is simple, practical, convenient and rapid; and the battery airtightness water-detection device cooperates with an airtightness detection machine to carry out airtightness sampling inspection, thereby judging whether the airtightness detection machine works normally, decreasing fault ratio or omission ratio, and providing guarantee for battery quality.
Description
Technical field
The application relates to the battery production apparatus field, particularly relates to a kind of cell water that is used for and examines bubble-tight device.
Background technology
In the manufacturing process of battery, the poor sealing of battery sizes lid heat-sealing can cause battery to leak problems such as acid, influences battery quality; Therefore, need carry out airtight test to battery.Existing air-tightness detection method utilizes pressure transducer detected pressures difference to change and judges impermeability normally by form pressure differential inside and outside battery, and this is the General Principle of impermeability machines.But, in practical operation, only adopt the impermeability machines to detect, false retrieval or omission appear easily.
Summary of the invention
The application's purpose provides a kind of cell water that is used for and examines bubble-tight device, and this device is used to cooperate the impermeability machines that battery is carried out the impermeability sampling check.
The application has adopted following technical scheme:
The application discloses a kind of cell water that is used for and has examined bubble-tight device, comprise and detect frock and aerating device, the detection frock is a hollow tube, one end of hollow tube is the valve joint, by this valve joint, adopt flexible pipe that hollow tube is communicated with aerating device, the other end of hollow tube is the cell row air vent connector that is used to be communicated with the vent port of battery, is arranged with airtight plug on the shell of cell row air vent connector.
Further, airtight plug is a pyramidal structure.
Further, the handle that caves inward that has symmetry on the shell at the middle part of detection frock.
Among the application, the cell row air vent connector is a stainless joint.
The application's beneficial effect is:
The application's the cell water that is used for is examined bubble-tight device, and is simple in structure, and easy operating is simple and practical, can be in the extremely short time fast detecting big tegillum that goes out the battery heat-sealing whether leak gas; Be used to cooperate the impermeability machines that battery is carried out the impermeability sampling check, whether working properly, and can also reduce the probability of false retrieval or omission if not only can be used to detect the impermeability machines, for battery quality provides safeguard.
Description of drawings
Fig. 1 is that the cell water that is used for of the embodiment of the present application is examined the perspective view that bubble-tight device detects frock;
Fig. 2 is that the cell water that is used for of the embodiment of the present application is examined the Facad structure synoptic diagram that bubble-tight device detects frock;
Fig. 3 is that the cell water that is used for of the embodiment of the present application is examined the A-A cut-open view that bubble-tight device detects frock;
Fig. 4 is that the cell water that is used for of the embodiment of the present application is examined bubble-tight device and carried out the syndeton synoptic diagram of impermeability when detecting.
Embodiment
The problem that occurs false retrieval or omission at existing impermeability machines easily, the application provides a kind of device that cooperates the impermeability machines battery to be carried out the impermeability sampling check, this device comprises detection frock and aerating device, the detection frock is a hollow tube, one end of hollow tube is the valve joint, by this valve joint, adopt flexible pipe that hollow tube is communicated with aerating device, the other end of hollow tube is the cell row air vent connector that is used to be communicated with the vent port of battery, is arranged with airtight plug on the shell of cell row air vent connector.During detection, the cell row air vent connector is inserted in the vent port of battery, airtight plug is used to ensure the impermeability of connection, avoids gas leakage; Whether after connecting, other vent port of battery is clogged, as in the tank, the water surface in the tank did not have battery with battery, inflated to battery by aerating device then, only needed for 3 seconds and can detect the big tegillum of battery heat-sealing to leak gas, and was convenient and swift.
The application is further, and airtight plug is designed to pyramidal structure, with better assurance impermeability.Further, the handle that caves inward of design symmetry on the shell at the middle part of detecting frock, so that grip, and conveniently will detect the vent port that frock is inserted battery.In addition, the cell row air vent connector adopts the stainless steel preparation, is corroded avoiding.
Need to prove that according to the battery of different model, the size of its vent port is also possible different, therefore, only need get final product the size adjustment of the cell row air vent connector of the application's detection frock.
Also in conjunction with the accompanying drawings the application is described in further detail below by specific embodiment.Following examples only further specify the application, should not be construed as the restriction to the application.
Embodiment
The cell water that is used for of this example is examined bubble-tight device, shown in Fig. 1-4, comprise and detect frock 5 and aerating device 7, detecting frock 5 is hollow tube, one end of hollow tube is the valve joint 4 that is used to be communicated with aerating device, the other end of hollow tube is the cell row air vent connector 1 that is used to be communicated with the vent port of battery, be arranged with airtight plug 2 on the shell of cell row air vent connector, airtight plug 2 is a pyramidal structure, the cell row air vent connector is a stainless joint, the handle that caves inward 3 that has symmetry on the shell at the middle part of detection frock by detecting the valve joint 4 of frock, adopts flexible pipe 6 will detect frock 5 and is communicated with aerating device 7.
During use, will detect one of them vent port 11 of the cell row air vent connector 1 insertion battery 9 of frock 5, and other vent port of battery is clogged, put into tank 8 with connecting the battery that detects frock, water in the tank 8 did not have battery 9, opened the valve of aerating device 7 then, to battery 9 inflations.Wherein also be provided with on the battery 9 and be convenient to the handle 10 that battery is taken from tank.If emit bubble around the battery case top, represent that then the big lid heat-sealing of battery is bad, if emit bubble in the middle of the battery top, represent that then the tegillum heat-sealing of battery is bad; Judge whether battery sizes lid leaks gas and only needed to finish for three seconds from being inflated to.
This routine apparatus structure is simple, and easy operating is easy to detect quick.Adopt this device that the battery that detects through the impermeability machines is surveyed sample, not only can judge whether operate as normal of impermeability machines, can also reduce the probability of false retrieval or omission, for the quality of battery provides guarantee.
Above content be in conjunction with concrete embodiment to further describing that the application did, can not assert that the application's concrete enforcement is confined to these explanations.For the application person of ordinary skill in the field, under the prerequisite that does not break away from the application's design, can also make some simple deduction or replace, all should be considered as belonging to the application's protection domain.
