The operation of the injection device 100 is substantially as follows: the tray driving mechanism 42 drives the tray 40 to be separated from the pressure shell 50, a plurality of battery shells which are not injected with liquid are arranged on the tray 40, then the battery shells are in one-to-one correspondence with the accommodating holes 530, the tray driving mechanism 42 drives the tray 40 to tightly abut against the pressure shell 50 to form a closed cavity, the pressure rod driving mechanism 22 quantitatively drives the downward moving distance of the pressure rod 20 to quantitatively inject the electrolyte in the accommodating cavity 13 into the battery shells, meanwhile, the pressure device performs vacuumizing and pressurizing on the pressure cavity in a circulating mode, so that the electrolyte can be more fully permeated into the battery shells, and after liquid injection is completed, batteries on the tray 40 are replaced.
Referring to fig. 10, fig. 10 is a schematic structural diagram of an embodiment of a battery production system provided in the present application.
The battery production system 200 includes the liquid injection device 100 as described above.
For example, a battery that has not been filled with liquid is automatically loaded on the tray 40 by an industrial robot or the like, and after the liquid filling device 100 completes the liquid filling of the battery, the battery that has been filled with liquid is transported to the next station, thereby realizing the full automation of the battery production process.
Being different from the situation of the prior art, the application discloses priming device and battery production system. Through setting up the liquid cup of holding of definite size and pouring into quantitative liquid to holding the holding intracavity that liquid cup and liquid cup base formed to ration control depression bar moves down the distance in moving down holding the liquid cup, annotate the liquid pipe to the work piece through first notes liquid pipe, second quantitatively, and then realize annotating the liquid to the work piece accuracy, improved priming device's notes liquid precision, it is long to have shortened notes liquid.
The above description is only an example of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings, or which are directly or indirectly applied to other related technical fields, are intended to be included within the scope of the present application.
