Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to a negative pressure acid absorption device for a battery cover. Background Art

[0002] During the production process of batteries, acid injection operations are required. There are multiple acid injection ports on the battery box. The acid injection ports are generally concave. After the acid is injected and charged, acid extraction operations are required. Then, a safety valve will be installed on the acid injection port. During this series of operations, some acid will remain around the acid injection port, and these residual acid needs to be processed.

[0003] The general treatment method now is to install the safety valve to the acid injection port, and then use a flushing machine to flush away the residual acid on the battery box. However, as the amount of flushing acid increases, the acid content of the flushing water also increases. Therefore, when discharging the flushing water, it is necessary to neutralize the flushing water to ensure that the flushing water meets the discharge standards. This residual acid treatment method not only wastes water resources, but also increases the production cost of the enterprise. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-2As shown, a negative pressure acid absorption device for a battery cover comprises a tank body 6, a negative pressure device 8 and a linear drive device 2, wherein the linear drive device 2 is a cylinder or a hydraulic cylinder, and the driving end of the linear drive device 2 is connected to a plate body 1, and a plurality of groups of suction nozzles 4 are connected to the bottom of the plate body 1, and the plurality of groups of suction nozzles 4 are connected to each other through a hose 5, wherein one end of the hose 5 connected to one of the suction nozzles 4 is connected to the tank body 6 and a first valve 11 is provided on this part of the hose 5, and the suction end of the negative pressure device 8 is connected to the tank body 6.

[0022] In the present embodiment, the negative pressure device 8 is a vacuum pump with a built-in pressure gauge. The negative pressure device 8 can evacuate the tank body 6, thereby making the tank body 6 in a negative pressure state, and the linear drive device 2 can drive the plate body 1 to descend, so that multiple groups of suction nozzles 4 are respectively covered above the acid injection port of the battery box body. At this time, since a safety valve is provided in the acid injection port and the suction nozzle 4 is in close contact with the battery box, a sealed cavity is formed between the suction nozzle 4 and the battery box. Then, the first valve 11 is opened, and the tank body 6 will absorb the acid liquid remaining on the surface of the acid injection port of the battery box body through the suction nozzle 4, so that when the residual acid liquid is flushed with a flushing machine, water resources can be saved, and as the amount of flushing water is reduced, the cost of purifying the flushing water is also reduced, thereby improving efficiency.

[0023] The nozzle 4 is fixedly connected to the plate body 1 through the elastic component 3. Figure 2 As shown, the elastic component 3 includes a cylinder 301 fixed to the bottom of the plate body 1, an elastic member 302 is fixed in the cylinder 301, a connecting rod 303 is connected to the bottom of the elastic member 302, and the bottom of the connecting rod 303 extends out of the cylinder 301 to be fixedly connected to the suction nozzle 4, wherein the elastic member 302 is a cylindrical spring;

[0024] Since the shell is made of plastic and there is a certain error in the top flatness, when the linear drive device 2 drives the plate 1 to descend to prompt the suction nozzle 4 to contact the battery box body, the elastic member 302 will make the suction nozzle 4 have a certain buffering performance, thereby preventing the suction nozzle 4 from directly compressing and deforming the battery box body, and the elastic member 302 is located as a whole in the cylinder 301, so the cylinder 301 can protect the elastic member 302 and avoid the elastic member 302 from being directly exposed, thereby reducing the possibility of the elastic member 302 being skewed due to external force.

[0025] Among them, Figure 2 As shown, a rubber ring 12 is provided at the bottom of the suction nozzle 4. When the suction nozzle 4 contacts the battery box body, the rubber ring 12 will deform, thereby improving the sealing of the cavity formed after the suction nozzle 4 contacts the battery box body, so as to ensure the normal negative pressure acid suction operation.

[0026] Among them, Figure 1As shown, a liquid level gauge 7 is provided on the tank body 6, and a detection end of the liquid level gauge 7 is located inside the tank body 6. The liquid level height of the acid liquid in the tank body 6 can be known through the liquid level gauge 7, so that personnel can discharge the acid liquid in time.

[0027] Among them, Figure 1 As shown, a drain pipe 9 is provided at the bottom of one end of the tank body 6, and a second valve 10 is provided on the drain pipe 9. When the amount of acid liquid in the tank body 6 reaches a certain value, the personnel opens the second valve 10 to discharge the acid liquid in the tank body 6 into a designated container through the drain pipe 9.

[0028] Working principle, first fix the linear drive device 2 on the conveyor belt of the production line, and ensure that the suction nozzle 4 points to the battery box conveyed by the conveyor belt, and then use the negative pressure device 8 to evacuate the tank body 6. In the next step, when the battery box equipped with a safety valve is transported to the bottom of the suction nozzle 4 via the conveyor belt, the personnel controls the linear drive device 2 to work, which can drive the plate body 1 to descend, so that multiple groups of suction nozzles 4 are respectively covered above the acid injection port of the battery box body. At this time, since a safety valve is provided in the acid injection port and the suction nozzle 4 is in close contact with the battery box, a sealed cavity is formed between the suction nozzle 4 and the battery box. Then, the first valve 11 is opened, and the tank body 6 will absorb the acid remaining on the surface of the acid injection port of the battery box body through the suction nozzle 4, so that when the residual acid is flushed with a flushing machine, water resources can be saved, and as the amount of flushing water is reduced, the cost of purifying the flushing water is also reduced, thereby improving efficiency.

[0029] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
