Abstract
The utility model relates to a weighing and liquid injection control system for a lithium battery, and the control system comprises a master control module which is connected with two or more functional modules in a distributed-control manner. The functional modules are respectively connected with a filling weighing platform in a sampling manner, and are respectively connected with a ratio-adjusting valve in an output-control manner, wherein the ratio-adjusting valve is used for liquid injection. According to the scheme of the utility model, the quantity of liquid injection is measured in a weighing mode. The quantity of liquid injection is compared and judged through the functional modules and/or the master control module, so as to control the ratio-adjusting valve, thereby controlling the quantity of liquid injection precisely.
Description
Technical field
The utility model relates to a kind of lithium battery fluid injection control system of weighing.
Background technology
The lithium battery fluid injection mode that industry generally adopts at present: first electrolytic solution is extracted into transfer tank, then with volume pump, electrolytic solution is extracted in fluid injection cup by setting value, then injects the electrolyte into inside battery with fluid injection cup.The defect of this method is: process link is many, and pipeline is complicated, and precision is on the low side, and poor stability, and electrolytic solution leakage is serious.
Utility model content
The purpose of this utility model is to provide a kind of lithium battery fluid injection control system of weighing, in order to solve existing cubing mode precision shortcoming on the low side.
For achieving the above object, scheme of the present utility model is: the lithium battery fluid injection control system of weighing, comprises main control module, the plural functional module of the distributed control linkage of main control module, functional module sampling connects filling weighing platform, and control linkage is for the ratio adjusting valve of fluid injection.
Described main control module is also connected with man-machine interface touch-screen.
Main control module is connected by CAN bus with functional module.
Main control module, functional module concentrated setting are in field control cabinet.
The lithium battery of the present utility model fluid injection control system of weighing adopts functional module sampling to connect weighing platform, by weighting manner, measure reservoir quantity, and by functional module and/or main control module, relatively judge that reservoir quantity is with control ratio variable valve, thereby accurately control reservoir quantity.In addition, can also simplify the operation course, reduce pipeline, increase stability.
Accompanying drawing explanation
Fig. 1 is system diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in more detail.
The lithium battery fluid injection control system of weighing, comprises main control module, the plural functional module of the distributed control linkage of main control module, and functional module sampling connects filling weighing platform, and control linkage is for the ratio adjusting valve of fluid injection.By weighting manner, measure reservoir quantity, and relatively judge that by functional module and/or main control module reservoir quantity is with control ratio variable valve, thereby accurately control reservoir quantity.
It shown in Fig. 1, is a kind of preferred implementation, mainly comprise the mechanical assemblies such as the man-machine interface touch-screen for man-machine interaction, the main control module that adopts MC700, the functional module that adopts TR700, on-the-spot filling weighing platform, proportional governor, the mechanical assemblies such as proportional governor of the filling weighing platform in scene wherein, the fluid injection of control lithium battery belong to prior art, do not repeat them here.The signals such as weight data that main control module MC700 acquisition function module TR700 uploads, by the aim parameter comparison of weight data and setting, according to the input/output state of switching value to functional module TR700 output action signal; Functional module TR700 gathers the weight data that filling scale is measured, and the signals such as weight data are uploaded to main control module MC700, and completes lithium battery fluid injection action according to the signal controlling proportional governor of main control module MC700 output.Main control module MC700 is connected by CAN fieldbus with functional module TR700, and message transmission rate is high, distance, and strong interference immunity can effectively reduce field wiring.The every cover lithium battery being connected with the main control module MC700 priming device of weighing can work independently.Computing machine is mainly responsible for the functions such as data management, Report Server Management, formulation management, user management.
As other embodiments, the function that the weight data of collection and target setting are relatively judged also can complete in functional module.
