Description
Technical field
The utility model belongs to battery testing technical field, relates to a kind of simple and easy battery vacuum leak detection device.
Background technology
It is the detection of battery in production procedure that battery leaks hunting, and after cover plate and housing welding, tests its welded seal effect, to complete the requirement of quality, safety and the environmental protection of whole battery.The detection of at present battery being leaked hunting is all to test after battery production completes again, the product that assurance flows to market is the product that sealing property is qualified, but when the poor battery of sealing is done over again, the electrolytic solution in battery case need to be poured out and just can carry out afterwards, easily cause the wasting of resources.
At Chinese patent Granted publication number, be CN 202420779 U, Granted publication day is 2012.09.05, and name is called in the patent documentation of " lithium battery leak-checking apparatus " and discloses a kind of device that lithium battery is leaked hunting.This device comprises transparent airtight container, also comprises the vacuum source that one end is stretched into the draft tube in described airtight container and airtight container is vacuumized, and in described draft tube, is provided with gas admittance valve, between described vacuum source and airtight container, is provided with air outlet valve.Although this leak-checking apparatus has solved the existing wasting of resources problem of leaking hunting caused after inconvenience, injection electrolytic solution of using of existing lithium battery leak-checking apparatus, but when detecting, if it is improper to control, solution in airtight container is easy to suck-back and enters battery, and the battery of test also will be scrapped so.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, provide a kind of device simple, easy to detect, because misoperation causes solution suck-back, enter detected battery while preventing from detecting, thereby damage the simple and easy battery vacuum leak detection device of detected battery.
The purpose of this utility model is achieved through the following technical solutions: a kind of simple and easy battery vacuum leak detection device, comprise and detect bottle, battery connecting pipe, escape pipe, vacuum pump and cell fixing device, also comprise surge flask and separator tube, surge flask is detecting between bottle and cell fixing device; One end of battery connecting pipe is connected with cell fixing device, and the other end is positioned at surge flask; Separator tube one end is positioned at surge flask, and the other end is arranged in and detects bottle; Escape pipe one end is arranged in detects bottle, and the other end is connected with vacuum pump, by battery connecting pipe, separator tube and escape pipe, package unit is coupled together.
Preferably, the described air intake opening of escape pipe in bottle that detects is higher than the gas outlet of separator tube.
Preferably, described battery connecting pipe is provided with the T-valve of belt switch, and one end of T-valve is communicated with atmosphere.
Preferably, described cell fixing device is provided with sealing-plug.
Preferably, described vacuum meter is installed on and detects between bottle and vacuum pump.
Preferably, described detection bottle and surge flask are transparent wide-necked bottle with rubber stopper detachable and that sealing is strong.
The utlity model has following advantage: the utility model has increased a surge flask, be provided with the T-valve of belt switch, leak-checking apparatus is simple to operation, convenient to be detected, and in the time of especially can preventing from detecting, because misoperation causes solution suck-back, enters detected battery, thereby damages detected battery; Detect the in-built electrolyte solvent of bottle, even if suck-back enters detected battery, also can not damage battery.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-detects bottle, 11-rubber stopper, 2-surge flask, 3-battery connecting pipe, 4-separator tube, 5-escape pipe, 6-vacuum meter, 7-vacuum pump, 8-T-valve, 9-cell fixing device, 91-sealing-plug.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1, the utility model is a kind of simple and easy battery vacuum leak detection device, comprise and detect bottle 1, battery connecting pipe 3, escape pipe 5, vacuum pump 7 and cell fixing device 9, also comprise surge flask 2 and separator tube 4, surge flask 2 is detecting between bottle 1 and cell fixing device 9; One end of battery connecting pipe 3 is connected with cell fixing device 9, and the other end is positioned at surge flask 2; Separator tube 4 one end are positioned at surge flask 2, and the other end is arranged in and detects bottle 1; Escape pipe 5 one end are arranged in detects bottle 1, and the other end is connected with vacuum pump 7, by battery connecting pipe 3, separator tube 4 and escape pipe 5, package unit is coupled together; Detect the air intake opening of bottle 1 interior escape pipe 5 higher than the gas outlet of separator tube 4; Battery connecting pipe 3 is provided with the T-valve 8 of belt switch, and one end of T-valve 8 is communicated with atmosphere; Cell fixing device 9 is provided with sealing-plug 91; Vacuum meter 6 is installed on and detects between bottle 1 and vacuum pump 7; Detect bottle 1 and surge flask 2 and be transparent wide-necked bottle and with rubber stopper 11 detachable and that sealing is strong.
During operation, first detecting bottle 1 interior injection electrolyte solvent, liquid height surpasses the gas outlet of separator tube 4 in bottle, guarantee package unit good seal, on cell fixing device 9, place battery to be detected, the switch of T-valve 8 is pushed to the direction that battery and surge flask 2 are communicated with, open vacuum pump 7, the gas of inside battery is extracted out to enter and detect bottle 1, can be observed to detect in bottle 1 has bubble to emerge.When the gas of inside battery is taken out to the greatest extent, while becoming vacuum state, if detect in bottle 1, no longer emit bubble, this battery sealing-performance is good, is certified products, simultaneously can recording vacuum gauge 6 readings, with for referencial use; If detect, bottle 1 is interior continues to have bubble to emerge, and this battery gas leakage is described, sealing is poor, needs again to do over again.After detection, close vacuum pump 7, the switch of T-valve 8 is pushed to the direction that battery and atmosphere are communicated with, can take off battery, carry out the test of next battery.
