Description
Technical field
The invention belongs to technical field of battery production, and in particular to a kind of management method of battery material.
Background technique
In intelligent manufacturing industry, it is of great significance for the timeliness control of material involved in processing procedure, product.Especially
In polymer lithium ion battery cell production, battery core after completion of assembly, needs to stand a period of time, makes electrolyte complete wetting for it
Pole piece is to cooperate formation process to form SEI film, thus the charging/discharging function for making battery core bring into normal play, and the material in battery core processing procedure
If very big influence may be caused to battery core end properties by standing time-out, thus cause battery core quality that cannot ensure, flow
Enter and is likely to result in biggish security risk in client.
In the production process of existing battery core, the material logistics of battery core rely primarily on manually by the data of materiel warehouse-in, when
Between be recorded on process paper, and human control material is carried out with this, still, mistake is once lost or filled in these process paper will
It is difficult accurate judgement material current state；And stringent verification, material timeout expirations are not carried out in the production process of battery core
Probability it is very high.
Therefore, it is badly in need of efficient, the accurate material management system of one kind to solve problem above.
Summary of the invention
It is an object of the invention to: in view of the deficiencies of the prior art, and a kind of management method of the battery material provided, it should
Method is able to achieve paperless management, accurately carries out control to the time of repose of battery core, meanwhile, also realization visual control, pole
The earth improves production efficiency, ensure that the quality of material.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of management method of battery material, comprising the following steps:
S1: it inbound registration: is scanned using two dimensional code of the information reading module to material, obtains the information of material and to the object
Material is registered；
S2: position distribution: main control module is allocated according to the position that the material information of acquisition stands material and passes through artificial
Material is pushed away to put to corresponding position and is stood；
S3: information is shown: the static condition information of material is fed back to display module by main control module, and is carried out by display module
Display；
S4: early warning and alarm: during material is stood, main control module is monitored the actual time of repose of material, and according to
The standing time limit of setting, in setting stand the time limit in material give warning in advance, and to already exceed setting stand when
The material of limit state is alarmed；
S5: confirmation is outbound: after the completion of material standing, whether operator may be used by the material state validation of information shown in S3
With outbound；
S6: finished product verification: it is verified after material is outbound and before entering next process, if noting abnormalities, there will be reports
It is alert to prompt and the information of material be retrieved, trace the step of going wrong.
The improvement of management method as battery material of the present invention, the information reading module are barcode scanning gun or tool
There are the smart phone, plate or computer of barcode scanning function.
The improvement of management method as battery material of the present invention, the display module are computer, plate, intelligence
TV or smart phone.
The improvement of management method as battery material of the present invention, when the status information of material includes inbound in S3
Between, bar code information, position number, model, the standing time limit for standing environment, the practical time of repose of material and setting.
The improvement of management method as battery material of the present invention, gives warning in advance in S4 or time-out alarm passes through
The status information of material is pushed to the smart machine of operator by the form of mail or short message.
The improvement of management method as battery material of the present invention enters the station to the registration of material according to material in S1
Sequencing arranged.
The shipment sequence of the improvement of management method as battery material of the present invention, material is stepped on according to material inbound
The sequence of note carries out preferential outbound.
The improvement of management method as battery material of the present invention enters the station to the registration of material according to material in S1
Batch carry out unified registration.
The improvement of management method as battery material of the present invention, the shipment sequence of material is according to unified registration
Sequence carries out unified outbound.
The beneficial effects of the present invention are: by above-mentioned processing step, the present invention realizes intelligent management, instead of
Manually-operated mode in the prior art, improves production efficiency；By display module, so that operator is quickly grasped material and work as
Preceding static condition and judge whether well can be outbound, realizes visualized management；It is effectively right by main control module
The time of repose of material is monitored, meanwhile, the function of prompting and alarm is also played to operator, thus allow operator preferably
Use is scheduled to the material not exceeded the time limit and avoids the quality for improving battery core finished product using the material to exceed the time limit；In addition, also
It is verified after material is outbound, further reduces substandard products probability.
