[0031] The battery dissection process of the utility model is as follows:

[0032] Start battery dissection. The main purpose of battery dissection is to separate the upper cover from the bottom groove. Take the 6-DZF20 battery as an example. Place the upper end of the battery downward close to the cylinder between the first limit plate 61 and the second limit plate 62.

Start the cylinder again. The battery is in the telescopic position. The rod pushes the saw blade, and the two vertical saws cut the upper part of the battery bus at a preset spacing.

Start the cylinder again to retract the telescopic rod and bring the battery back to its original position, and the dissection of the battery is basically completed. For failed batteries, because their pole plate grids are usually corroded or the pole group is expanded, it is difficult to remove the pole group smoothly. In order to remove the pole group without loss, the battery with the upper cover removed is laid flat, and the cutting is performed along the single grid partition according to the above steps.

[0051] For failed batteries, since their plate grids are usually corroded or the pole groups are expanded, it is difficult to remove the pole groups smoothly. In order to remove the pole groups without damage, the battery with the upper cover removed is laid flat, and the above steps are followed to cut along the single grid partition. Repeat the operation to remove the pole groups. In order to determine the cause of failure, the partition acid density is usually measured. The failed battery partition contains very little acid, and it is very difficult to squeeze it out manually. Therefore, an acid squeezing component 7 and a liquid density meter 9 are set on the workbench.

[0053] Place the target partition in the acid extrusion cylinder, and use the handle to turn the acid extrusion bolt to make the partition precipitate acid under the squeezing of the acid extrusion block and the porous stage until the acid amount meets the measurement requirements.
