Abstract
The invention relates to a device and a method for detecting leak of an upper cover of a power battery. The device is characterized in that a vertically-arranged air cylinder is fixed on a support, the lower end of an air cylinder lever is connected with a plugging head for upper battery covers, and a bracket for upper battery covers is arranged below the plugging head for the upper battery covers; and the plugging head for the upper battery covers is connected with an air charge valve, and the lower end of the plugging head for the upper battery covers is provided with an air outlet. The method comprises the following steps: in the process of leak detection, placing the upper cover of the power battery on the bracket for upper battery covers, and operating an air charge valve of the air cylinder, so that the cylinder lever of the air cylinder moves downwards until the plugging head for upper battery covers is pressed against a connector of an explosion-proof valve of the upper cover of the power battery; and starting the air charge valve so as to carry out leak detection on the upper cover of the power battery.
Description
Technical field
The present invention relates to electrokinetic cell loam cake leak-checking apparatus and method.
Background technology
In the prior art, the leak-checking apparatus structure of electrokinetic cell loam cake is comparatively complicated, and the validity of leaking hunting is relatively poor.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of electrokinetic cell loam cake leak-checking apparatus and method, can effectively realize leaking hunting of electrokinetic cell loam cake.
Based on same inventive concept, the present invention has two independently technical schemes:
1, a kind of electrokinetic cell loam cake leak-checking apparatus is fixed with the cylinder of vertical setting on the support, it is characterized in that: the lower end of cylinder cylinder bar is connected to the cell cover block head, and the below of cell cover block head is provided with the cell cover carriage; Described cell cover block head is connected to gas filling valve, and has the gas outlet in the lower end of cell cover block head.
The cell cover carriage is made up of two carriages, forms air reservoir between two carriages.
2, a kind of leak detection method that utilizes said apparatus is characterized in that: the electrokinetic cell loam cake is placed on the cell cover carriage, and operation cylinder scavenging air valve moves downward cylinder cylinder bar, compresses until cell cover block head and electrokinetic cell loam cake explosion-proof valve interface; Open gas filling valve, the electrokinetic cell loam cake is leaked hunting.
Leak hunting finish after, close gas filling valve, the operation cylinder, cylinder cylinder bar is moved upward, thereby makes the cell cover block head leave electrokinetic cell loam cake explosion-proof valve interface.
The beneficial effect that the present invention has:
Anchor clamps of the present invention adopt pneumatic system control, and the lower end of cylinder cylinder bar is connected to the cell cover block head, and the below of cell cover block head is provided with the cell cover carriage; The cell cover block head is connected to gas filling valve, and has the gas outlet in the lower end of cell cover block head.When leaking hunting, only need control cylinder, block head and electrokinetic cell loam cake explosion-proof valve interface are compressed, opening gas filling valve can leak hunting.Structural design advantages of simple of the present invention, volume is little, cost is low, in light weight, the operation simple and easy, failure rate is low, it is effective to leak hunting.The present invention is applied widely, not only is confined to 40AH box hat electrokinetic cell, and applicable multiple box hat electrokinetic cell loam cake both positive and negative polarity is lived and the explosion-proof valve seal leakage detects, and can effectively improve the qualification rate of battery production.
Description of drawings
Fig. 1 is the structural representation of electrokinetic cell loam cake leak-checking apparatus of the present invention;
Fig. 2 is the side view of Fig. 1.
Embodiment
As shown in Figure 1, be fixed with the cylinder 2 of vertical setting on the support 1, the lower end of cylinder cylinder bar 7 is connected to cell cover block head 4, and the cell cover block head is connected to gas filling valve 6, and has the gas outlet in the lower end of cell cover block head.The below of cell cover block head is provided with cell cover carriage 3, and is as shown in Figure 2, and the cell cover carriage is made up of two carriages, forms air reservoir 5 between two carriages.
When leaking hunting; Leak-checking apparatus is placed in the station box that fills liquid (like alcohol or water), the electrokinetic cell loam cake is placed on the cell cover carriage 3, operation cylinder scavenging air valve; Cylinder cylinder bar 7 is moved downward, compress until cell cover block head 4 and electrokinetic cell loam cake explosion-proof valve interface; Open gas filling valve 6; Gas is discharged by the gas outlet of cell cover block head 4 lower ends, gets in the air reservoir 5, if there is leak source at cell cover soldered place; The bubble that the liquid level of corresponding leak source position has clearly changes, thereby realizes the detection to the cell cover leak source.Leak hunting finish after, close gas filling valve 6, the operation cylinder, cylinder cylinder bar 7 is moved upward, thereby makes cell cover block head 4 leave electrokinetic cell loam cake explosion-proof valve interface.
Claims (4)
1. electrokinetic cell loam cake leak-checking apparatus is fixed with the cylinder of vertical setting on the support, it is characterized in that: the lower end of cylinder cylinder bar is connected to the cell cover block head, and the below of cell cover block head is provided with the cell cover carriage; Described cell cover block head is connected to gas filling valve, and has the gas outlet in the lower end of cell cover block head.
2. electrokinetic cell loam cake leak-checking apparatus according to claim 1 is characterized in that: the cell cover carriage is made up of two carriages, forms air reservoir between two carriages.
3. leak detection method that utilizes the said device of claim 1; It is characterized in that: the electrokinetic cell loam cake is placed on the cell cover carriage; Operation cylinder scavenging air valve moves downward cylinder cylinder bar, compresses until cell cover block head and electrokinetic cell loam cake explosion-proof valve interface; Open gas filling valve, the electrokinetic cell loam cake is leaked hunting.
4. leak detection method according to claim 3 is characterized in that: leak hunting finish after, close gas filling valve, the operation cylinder, cylinder cylinder bar is moved upward, thereby makes the cell cover block head leave electrokinetic cell loam cake explosion-proof valve interface.
