Description
Technical field
The utility model relates to a kind of leakage detection apparatus, relates in particular to a kind of battery leakage detection apparatus.
Background technology
Battery of electric vehicle belongs to lithium ion battery.Each unit of lithium ion battery also divides positive pole and negative pole.The positive electrode of lithium ion battery is made up of the reactive compound of lithium usually, and common positive electrode principal ingredient is LiCoO2, and negative pole then is the carbon of special molecular structure.Material anodal and the negative pole store electrical energy is referred to as active substance.The main effect of electrolytic solution is the temperature when participating in chemical reaction, the conducting ion on the pole plate and reducing cell reaction.Separated by dividing plate between the positive pole of accumulator and the negative pole, the dividing plate of accumulator needs sealing.
The box hat battery case is square box hat in the enterprise, is made up of the logical box hat in two and bottom, top cover, after assembling finishes, seals through Laser Welding (LBW).In the prior art, adopt earlier range estimation, observe whether weld seam is arranged, the sand holes that whether exist rosin joint to produce, whether crator is even, but these are often inaccurate by result that range estimation obtains, cause production efficient low, and product quality is not up to standard.
The utility model content
The technical problems to be solved in the utility model is: product utilizes visual observations whether weld seam is arranged in process of production, the sand holes that whether exist rosin joint to produce, and whether crator is even, because range estimation is inaccurate, cause production efficient low, product quality is not up to standard, and a kind of battery leakage detection apparatus is provided.
In order to overcome the defective that exists in the background technology, the technical scheme that its technical matters that solves the utility model adopts is: this battery leakage detection apparatus comprises battery, liquid injection hole, air-tight bottle and closed conduit, closed conduit connects battery and air-tight bottle, air-tight bottle is provided with output channel, and output channel is provided with vacuum meter and manually-operated gate.
According to another embodiment of the present utility model, comprise that further described closed conduit connects battery by liquid injection hole.
According to another embodiment of the present utility model, comprise that further described closed conduit connects air-tight bottle by stopper.
The beneficial effects of the utility model: this battery leakage detection apparatus is simple in structure, safe and reliable, with low cost, simple to operation, has improved product quality, has improved production efficiency of products.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Wherein: 1, vacuum meter, 2, manually-operated gate, 3, liquid injection hole, 4, battery, 5, closed conduit, 6, air-tight bottle, 7, stopper, 8, output channel.

The general bottom of weldering earlier in practical operation, when whether the check bottom seals, earlier other end port is tightly pressed on silica gel plate (silica gel is very soft, good airproof performance), the hole is arranged on the silica gel plate, connect the battery leakage detection apparatus, the gas that output channel 8 is extracted out in the air-tight bottle, vacuum meter 1 shows vacuum, turn off valve, vacuum tightness can keep, and does not emit bubble in the bottle, then illustrates air tight.
Behind the weldering top cover, whole housing has only top cover one jiao an aperture to be arranged, aperture is a liquid injection hole 3, when whether the detection top cover seals, liquid injection hole 3 is connected the battery leakage detection apparatus, vacuumize, owing to have air in the body after the inherent fluid injection of battery, connect battery 4 and air-tight bottle 6 by closed conduit 5, in the air-tight bottle 6 water is housed, if in the battery 4 gas is arranged, insert the sealed tube meeting bubbling of water, the gas that output channel 8 is extracted out in the air-tight bottles 6, vacuum meter 1 shows vacuum, turn off valve, vacuum tightness can keep, and does not emit bubble in the bottle, then illustrates air tight, after detection finished, liquid injection hole 3 usefulness glue sealed.
This battery vacuum leak detector is simple to operation, and apparatus structure is simple, and is safe and reliable, with low cost, and this device has improved product quality, has improved production efficiency of products.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the instructions, must determine its technical scope according to the claim scope.
