Description

Technical Field

[0001] This invention relates to the field of metal processing technology, and specifically to a control system and method for optimizing the thickness of aluminum foil rolled for batteries. Background Technology

[0002] With the development of new energy vehicles, the demand for power batteries has grown rapidly. Current collectors are one of the important components in power batteries, and aluminum foil, as the positive electrode current collector material for lithium-ion batteries, has been widely used. In recent years, the development of power batteries has entered the stage of large modules and module elimination, placing higher demands on the thickness accuracy and consistency, shape, and surface quality of aluminum foil. Existing aluminum foil rolling mill systems generally include a transmission control system for drive control, an auxiliary control programmable controller for exchanging control information with the transmission control system, and a thickness control programmable controller for controlling the thickness of the rolled aluminum foil. In traditional systems, the thickness control programmable controller is generally relatively independent from the auxiliary control programmable controller and the transmission control system, resulting in low automation in controlling the thickness of the rolled aluminum foil, and the rolling accuracy and consistency of the aluminum foil products cannot be guaranteed.

[0035] S2. Data Acquisition: Data is collected during the aluminum foil rolling process for batteries;

[0036] S3. Data storage: Store the parameters preset by the parameter preset unit and the data collected by the data acquisition unit;

[0037] S4. Data Analysis and Processing: Analyze and process the parameters preset by the parameter preset unit and the data obtained by the data acquisition unit.

[0042]

[0043] Therefore, the necessity of maintenance during the battery aluminum foil rolling process is determined based on the maintenance index of the battery aluminum foil rolling machinery. The higher the maintenance index, the more necessary the maintenance. When the maintenance index reaches the preset maintenance threshold, the instruction issuing module sends an instruction to the monitoring and warning unit, and the warning reminder module reminds the operator to perform timely maintenance on the battery aluminum foil rolling machinery. Here, JI represents the maintenance index of the battery aluminum foil rolling machinery, and H... i H represents the battery aluminum foil thickness when the thickness is abnormal, L1 represents the starting length when the thickness is abnormal, L2 represents the ending length when the thickness is abnormal, and n represents the number of adjustments when the thickness is abnormal.

[0044] Beneficial Effects: The control system of this invention has a high degree of automation, effectively ensuring the precision and consistency of aluminum foil rolling. First, various parameters required during the battery aluminum foil rolling process are preset. Then, these parameters are collected during the rolling process. The core processing unit analyzes and processes these parameters, and based on the analysis results, issues corresponding instructions to automatically and in real-time adjust the rolling of the battery aluminum foil, ensuring timely correction. On the other hand, by acquiring data on the battery aluminum foil thickness, rolling pressure, starting length, ending length, and number of adjustments when thickness anomalies occur during the rolling process, and analyzing this data to obtain a maintenance index for the battery aluminum foil rolling machinery, a command is sent to the monitoring and warning unit via the command issuance module when the maintenance index reaches a preset maintenance threshold. The warning and reminder module then alerts the operator to promptly inspect the battery aluminum foil rolling machinery to ensure rolling quality. Attached Figure Description

[0076] The control method for optimizing the thickness of aluminum foil rolling in batteries based on the above control system specifically includes the following steps:

[0077] Step 1, Parameter Preset: The aluminum foil thickness preset module, roll gap preset module, and maintenance index threshold preset module of the parameter preset unit are used to preset the thickness of the battery aluminum foil to be rolled, the roll gap of the battery aluminum foil rolling machine, and the threshold of the maintenance index during the battery aluminum foil rolling process.

[0078] Step 2, Data Acquisition: The data acquisition unit uses the aluminum foil thickness acquisition module, roll gap acquisition module, rolling pressure acquisition module, rolling length acquisition module, and adjustment number acquisition module to collect data on the thickness of the battery aluminum foil, the roll gap of the rolling machinery, the rolling pressure of the rolling machinery, the rolling length data, and the number of adjustments made during the battery aluminum foil rolling process due to the thickness of the rolled aluminum foil not meeting the requirements.

[0079] Step 3: Data storage: Store and manage the parameters preset by the parameter preset unit and the data collected by the data acquisition unit.

[0080] Step 4: Data Analysis and Processing: The core processing unit acquires the parameters preset by the parameter preset unit and the data collected by the data acquisition unit through the data acquisition module. The acquired data is then analyzed and processed by the analysis and processing module. During the analysis and processing, if the thickness of the battery aluminum foil is greater than the preset thickness, the instruction sending module sends an instruction to the automatic control unit to reduce the roll gap to reduce the thickness of the rolled battery aluminum foil. Conversely, if the thickness is less than the preset thickness, the instruction sending module sends an instruction to the automatic control unit to increase the roll gap to increase the thickness of the rolled battery aluminum foil. At the same time, the starting length and ending length of the abnormally thick battery aluminum foil are recorded and transmitted to the data storage unit.

[0081] On the other hand, during the analysis and processing, the thickness of the battery aluminum foil, rolling pressure, starting length, ending length, and number of adjustments during the battery aluminum foil rolling process are obtained when thickness abnormalities occur. Based on the data obtained above, the maintenance index of the battery aluminum foil rolling machinery is obtained through analysis and processing.

[0082]

[0083] Therefore, the necessity of maintenance during the battery aluminum foil rolling process is determined based on the maintenance index of the battery aluminum foil rolling machinery. The higher the maintenance index, the more necessary the maintenance. When the maintenance index reaches the preset maintenance threshold, the instruction issuing module sends an instruction to the monitoring and warning unit, and the warning reminder module reminds the operator to perform timely maintenance on the battery aluminum foil rolling machinery. Here, JI represents the maintenance index of the battery aluminum foil rolling machinery, and H... iH is the battery aluminum foil thickness when the thickness is abnormal, L1 is the starting length when the thickness is abnormal, L2 is the ending length when the thickness is abnormal, and n is the number of adjustments when the thickness is abnormal.

[0084] Then, the report generation module generates a report on the battery aluminum foil rolling process based on the results obtained from the analysis and processing module. Finally, the generated report on the battery aluminum foil rolling process is transmitted to the data storage unit.

[0085] Step 5: Automatic control: The rolling of battery aluminum foil is automatically controlled according to the instructions issued by the instruction distribution module of the core processing unit to adjust the thickness of the rolled aluminum foil.

[0086] Step 6: Monitoring and Warning: The information acquisition module of the monitoring and warning unit obtains the report on the battery aluminum foil rolling process generated by the report generation module based on the analysis and processing results, as well as the instructions issued by the instruction issuing module. Then, the report display module displays the report on the battery aluminum foil rolling process obtained by the report acquisition module. Based on the report on the battery aluminum foil rolling process displayed by the report display module, the operator manually controls the battery aluminum foil rolling process through the manual control module. When the maintenance index reaches the preset maintenance threshold, the operator receives an instruction issued by the instruction issuing module and is warned.

[0087] While the above disclosure is provided, the scope of protection of this disclosure is not limited thereto.
