Problems solved by technology

[0003] On the one hand, judging from the current production status of the enterprise, the link of chemical composition and capacity is still dominated by manual handling, manual loading and unloading of cabinets, manual sorting, and semi-automatic chemical forming equipment, and it is impossible to realize the integration of a single battery in the chemical forming process in production. Production traceability greatly limits the process of automation, digitalization, and intelligence of the entire battery equipment line. At the same time, it increases the labor cost of the enterprise, reduces production efficiency, and adds uncontrollable factors to the performance of the battery.
[0004] On the other hand, due to the const...

Embodiment 1

[0038] Such as figure 1 As shown, the power battery formation process intelligent dispatching and traceability system of this embodiment mainly includes battery container trays (also referred to as "container trays" or "battery trays", which will not be described in detail later), automatic coding and loading machines, grabbing Type AGV, chemical control cabinet, edge computing server, sorting device, and central server.

[0039] The battery container tray can adopt a three-dimensional structure with a square cross-section made of hard plastic, and the interior is divided into 10*10 matrix cells. Each cell is used to place a single battery, and the inside of the cell contains a slot structure. , used to fix the single battery. Optionally, in this embodiment, a low-frequency RFID tag is pasted on the side surface of the battery container tray for information identification of the battery container tray. Optionally, guide rail grooves are provided on both sides of each contain...

Embodiment 2

[0055] Corresponding to the above-mentioned system, this embodiment discloses a method for intelligent scheduling and traceability of a power battery formation process. The method includes the following steps:

[0056] (1) The coding control system associates the coding information of each group of batteries with the location information (A1-J10) of the battery container tray and the ID of the battery container tray.

[0057] (2) Upload and store the associated information in step (1) to the central server.

[0058] (3) At the beginning stage of forming into capacity, the edge computing server control program reads the ID of the battery container tray in each card slot through the RFID reader, and compares the time series data in the process of forming into capacity with each battery container tray ID in the corresponding container tray. location (A1-J10), stored locally in the form of a file, and uploaded to the central server after the completion of the content.

Abstract

The invention relates to the technical field of power batteries, and discloses an intelligent scheduling and tracing system and method for a power battery formation process, so as to realize scheduling intelligence and product tracing convenience in a production process. The system comprises a code printing and tray filling machine for printing battery codes; a battery container tray which is provided with a readable and writable RFID chip and matrix cells; a central server; a reader-writer for reading RFID chip information of the battery container tray which is arranged in each clamping groove structure of the formation cabinet; after the battery container tray is placed in the formation cabinet, the edge computing server controls the formation cabinet to perform a normal charging and discharging process according to the initialized production process, and records the charging and discharging data of each battery in system traceability associated information; the associated information further comprises RFID information of each battery code and the corresponding tray, coding information of corresponding cells in the tray and point location information of the formation cabinet; the system further comprises a sorting device for sorting the batteries according to the capacity sections based on the RFID chip information.

Description

technical field [0001] The invention relates to the technical field of power batteries, in particular to an intelligent scheduling and traceability system and method for the formation process of power batteries. Background technique [0002] The production and manufacturing process of power lithium batteries can be divided into four process segments: positive and negative electrode sheet production, cell assembly, cell activation detection, and battery packaging. Among them, the cell activation detection includes cell formation, capacity separation detection, etc. Composition and capacity is the key testing process for whether the consistency of battery cells, yield rate and other indicators can meet the requirements, and it is the last line of defense before battery packaging. [0003] On the one hand, judging from the current production status of the enterprise, the link of chemical composition and capacity is still dominated by manual handling, manual loading and unloadi...
