In the production of polymer lithium ion battery cells, the cell weight is the main cause of confusion of product traceability data and is an obstacle to the next processing of the battery cells. If the cell duplication codes appear, the following test and associated data are comprehensively disturbed, and the one-to-one product tracing effect cannot be achieved.
In the prior art, code spraying information is generally manually controlled and recorded, code spraying equipment is controlled independently, strict verification is not carried out in the production process, and the rate of code duplication of the code spraying of the battery cell is high.
Disclosure of Invention
The invention aims to: aiming at the defects of the prior art, the method for preventing the code duplication of the electrical core code spraying is provided, has a good code duplication prevention effect, is efficient and strong in real-time performance, and is suitable for large-scale automatic production.
In order to achieve the purpose, the invention adopts the following technical scheme:
a method for preventing code duplication of a code sprayed on a battery cell comprises the following steps:
automatically generating a bar code in a network database of a code spraying system, checking uniqueness, and sending an instruction to an ink spraying machine to spray the bar code on a battery cell;
secondly, carrying out top side sealing on the battery cell sprayed with the bar code obtained in the first step, scanning the bar code on the battery cell, comparing the bar code with the battery cell bar code which is subjected to top side sealing in a network database of a code spraying system, immediately alarming and stopping the operation of a top side sealing machine if a repeated code is found, and taking out the repeated code battery cell;
thirdly, performing liquid injection operation on the battery cell which is not subjected to the duplication in the second step, scanning a bar code on the battery cell, comparing the bar code with a liquid-injected battery cell bar code in a network database of a code spraying system, immediately alarming and stopping liquid injection if the duplication is found, and taking out the duplicate battery cell;
and step four, packaging the battery cell which is not duplicated in the step three, scanning the bar code on the battery cell, comparing the bar code with the packaged battery cell bar code in the network database of the code spraying system, and alarming if duplication is found.
It should be noted that the code spraying system in the invention can realize bar code distribution of by time, by machine and by factory.
And as an improvement of the method for preventing code duplication of the battery cell code, before comparing the bar codes in the second step, firstly recording the scanned bar codes in the PLC, then judging whether the duplicate codes exist according to the bar codes cached in the PLC, alarming and stopping the operation of the top side sealing machine if the duplicate codes exist, and taking out the duplicate battery cell. That is to say, before the battery cell performs network database duplicate code verification, the battery cell in the top side sealing process also performs local duplicate code verification. Because the cache of the PLC is limited, the barcode cached at the top can be replaced when the verification of one barcode is finished, so that the situation that the next barcode to be verified and the barcode just replaced are repeated can exist, that is, the duplication code verification of the machine is only the verification in a small range, the duplication code verification of the network database is the verification of the barcode in the whole database, and the duplication code verification of the network database can more effectively and comprehensively detect the duplication code cell, so that the cell duplication code can be better prevented.
In the second step, the top side sealing machine is informed to stop in a mode of returning a detection NG result through a software interface.
In the third step, the liquid injection equipment is notified to stop in a mode of returning a checking NG result through a software interface.
As an improvement of the method for preventing the code duplication of the code sprayed on the battery cell, the alarm form comprises at least one of a prompt message of 'duplicate alarm' and a sound prompt alarm displayed on a main page of the software.
Compared with the prior art, the invention has the beneficial effects that: on one hand, the uniqueness of the bar code is checked before code spraying, and repeated codes are prevented from the source; on the other hand, the method realizes multi-aspect calibration in a multi-channel battery cell production process, reduces the risk of repeated codes of manual operation, has high efficiency and strong real-time performance, and is suitable for large-scale automatic production.
