Description
Technical Field

[0002] With the continuous development of the new energy industry, the new energy vehicle manufacturing industry has also undergone repeated updates and iterations. The production process requirements for battery modules for new energy vehicles have become increasingly stringent, and the automation requirements and cycle time for battery module production have also increased accordingly. After the battery modules are completed in one process, they need to be removed from the production line. Traditionally, this is done manually by lifting and removing them from the production line. This has the following shortcomings: 1. It is impossible to accurately match and place battery modules according to demand and type, increasing the chance of misoperation in subsequent processes; 2. The cycle time for manual removal is too long, and the time required by different operators cannot be strictly consistent, affecting the stability of battery module removal operations.
[0003] Therefore, how to provide a battery module offline pairing method, system, equipment and medium to improve the quality and stability of battery modules offline has become a technical problem that needs to be solved urgently. Summary of the Invention

[0008] Step S30: The PLC verifies the battery module based on the module type and module photo.
[0009] Step S40: After the PLC locates the battery module using the camera, it controls the robot to transfer the battery module to the corresponding tray on the elevator based on the pairing rules and module type.

[0041] The embodiments of the present application provide a battery module offline pairing method, system, device and medium to improve the quality and stability of battery modules offline.
[0042] The technical solution in the embodiment of the present application has the following overall idea: the PLC controls the robot to transfer the battery module to the tray on the corresponding elevator based on the pairing rules and module type, writes the module type into the RFID chip in the tray through the RFID reader, and controls the elevator to perform offline operations on the battery module in the tray, so as to realize automatic offline pairing of the battery module, thereby improving the offline quality and stability of the battery module.
[0043] Example 1
[0044] This embodiment provides a battery module offline pairing method, such as Figure 1 As shown, the following steps are included:
[0045] Step S10: The PLC calibrates the camera on the robot and sets a pairing rule for the battery module.
[0046] Step S20: Based on the incoming material signal, the PLC controls the robot to move the camera to the left or right incoming material station, scan the barcode of the battery module with the camera to obtain the module type, and take a module photo of the battery module with the camera; the incoming material signal carries the incoming material direction, that is, whether the material is coming from the left or right incoming material station;
[0047] Step S30: The PLC verifies the battery module based on the module type and module photo.
[0048] Step S40: After the PLC locates the battery module using the camera, it controls the robot to transfer the battery module to the corresponding tray on the elevator based on the pairing rules and module type. The robot then returns to its original position and waits for the next cycle.
[0049] The PLC can identify three working states: code scanning, material picking, and material unloading, corresponding to three actions. If it is in the corresponding working state, it will start directly from the corresponding step after startup, thereby realizing rapid recovery of production;
[0050] In step S50, the PLC writes the module type into the RFID chip in the tray through the built-in RFID reader of the elevator, and controls the elevator to perform offline operations on the battery modules in the tray, while the empty tray continues to flow back to the elevator.
[0051] The present invention uses PLC as the control center to build a control system, scans the module information of the battery module through a camera, sets pairing rules in the PLC, and controls the robot to automatically classify and pair multiple groups of battery modules based on the pairing rules. The module type is written into the RFID chip of the pallet, so that when battery modules of different module types are irregularly fed through multiple channels, the battery modules can be automatically paired into groups and transported to the next process.
[0052] In step S10, the pairing rule is a team relationship of module types.
[0053] The step S30 is specifically as follows:
[0054] The PLC matches the module type through the MES system and determines whether the module type exists. If not, the battery module verification fails and the process ends. If yes, then:
[0055] Through machine learning technology, it is identified whether the wiring harness of the battery module in the module photo is installed correctly. If so, the battery module verification is successful and enters step S40; if not, the battery module verification fails and the process ends.
[0056] The step S40 is specifically as follows:
[0057] The PLC identifies the position coordinates of the battery module through a camera, calculates a corresponding coordinate offset based on the position coordinates, and moves the manipulator to grasp the battery module based on the coordinate offset;
[0058] The PLC determines whether the pallets of each elevator are empty. If so, it controls the robot to transfer the battery module to the pallet of any elevator. If not, the RFID reader of the elevator reads the module type of the battery module already loaded on the pallet, and based on the pairing rules and module type, controls the robot to transfer the battery module to the pallet on the corresponding elevator.
[0059] For example, there are four elevators, each capable of holding a pallet. Each pallet can be paired with a set of battery modules. Battery module types include M1, M2, M3, and M4. The pairing rule is that M1 and M2 form a team, and M3 and M4 form a team. If there are no battery modules on an elevator, any battery module can be placed. If there is already a battery module on an elevator, the robot will be given permission to place the corresponding battery module based on its module type. That is, if there are no battery modules on the left side of elevator No. 1 and the module type on the right side is M2, the robot can grab and place the battery module of M1; if the module type on the right side is M4, the robot can grab and place the battery module of M3.
[0060] Example 2
[0061] This embodiment provides a battery module offline pairing system, such as Figure 2 As shown, it includes the following modules:
[0062] A pairing rule setting module is used by the PLC to calibrate and verify the camera installed on the robot and set a pairing rule for the battery module;
[0063] The battery module scanning module is used to control the robot to move the camera to the left or right incoming material station based on the incoming material signal of the PLC. The camera scans the barcode of the battery module to obtain the module type and takes a module photo of the battery module. The incoming material signal carries the incoming material direction, that is, whether the material is coming from the left or right incoming material station.
[0064] A battery module verification module is used for PLC to verify the battery module through the module type and module photo;
[0065] The battery module transfer module is used to control the robot to transfer the battery module to the corresponding tray on the elevator after the PLC locates the battery module through the camera based on the pairing rules and module type. The robot then returns to its position and waits for the next cycle.
[0066] The PLC can identify three working states: code scanning, material picking, and material unloading, corresponding to three actions. If it is in the corresponding working state, it will start directly from the corresponding step after startup, thereby realizing rapid recovery of production;
[0067] The battery module offline module is used by the PLC to write the module type into the RFID chip in the pallet through the built-in RFID reader of the elevator, and control the elevator to perform offline operations on the battery modules in the pallet, while the empty pallet continues to flow back to the elevator.
[0068] The present invention uses PLC as the control center to build a control system, scans the module information of the battery module through a camera, sets pairing rules in the PLC, and controls the robot to automatically classify and pair multiple groups of battery modules based on the pairing rules. The module type is written into the RFID chip of the pallet, so that when battery modules of different module types are irregularly fed through multiple channels, the battery modules can be automatically paired into groups and transported to the next process.
[0069] In the pairing rule setting module, the pairing rule is a team relationship of module type.
[0070] The battery module verification module is specifically used for:
[0071] The PLC matches the module type through the MES system and determines whether the module type exists. If not, the battery module verification fails and the process ends. If yes, then:
[0072] Through machine learning technology, it is identified whether the wiring harness of the battery module in the module photo is installed correctly. If so, the battery module verification is successful and enters the battery module transplantation module; if not, the battery module verification fails and the process ends.
[0073] The battery module transplanting module is specifically used for:
[0074] The PLC identifies the position coordinates of the battery module through a camera, calculates a corresponding coordinate offset based on the position coordinates, and moves the manipulator to grasp the battery module based on the coordinate offset;
[0075] The PLC determines whether the pallets of each elevator are empty. If so, it controls the robot to transfer the battery module to the pallet of any elevator. If not, the RFID reader of the elevator reads the module type of the battery module already loaded on the pallet, and based on the pairing rules and module type, controls the robot to transfer the battery module to the pallet on the corresponding elevator.
[0076] For example, there are four elevators, each capable of holding a pallet. Each pallet can be paired with a set of battery modules. Battery module types include M1, M2, M3, and M4. The pairing rule is that M1 and M2 form a team, and M3 and M4 form a team. If there are no battery modules on an elevator, any battery module can be placed. If there is already a battery module on an elevator, the robot will be given permission to place the corresponding battery module based on its module type. That is, if there are no battery modules on the left side of elevator No. 1 and the module type on the right side is M2, the robot can grab and place the battery module of M1; if the module type on the right side is M4, the robot can grab and place the battery module of M3.
