[0002] With the continuous development of the new energy industry, the new energy vehicle manufacturing industry is also undergoing iterative updates, and the production process requirements for PACK battery packs of new energy vehicles are becoming increasingly stringent. The automation and rhythm of PACK battery pack assembly are also improving. The PACK battery pack is composed of a box loaded with several battery modules, and each battery module needs to be boxed according to a predetermined order.

Manual hoisting of battery modules may cause deviation in the boxing position, and the insulating strip of the battery module may be missed, and the battery module sorting may be incorrect, resulting in a low yield of the PACK battery pack; 2. The hoisting rhythm is too long, and the time required for operation by different people cannot be strictly uniform, resulting in low assembly stability; 3. Manual hoisting of battery modules poses a potential safety risk, and a fall of the battery module may cause personal injury accidents.

[0034] One or more technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages:

[0035] The PLC controls the PACK line and module line to transfer the housing and battery modules to the housing station and module station respectively. The PLC performs glue application verification on the housing and insulation strip verification and module type verification on the battery modules. Then, the PLC controls the robot to pick up the battery modules from the module station and take them to the cleaning station for plasma cleaning.

[0039] Figure 2 This is a schematic diagram of the structure of an automatic battery module loading system according to the present invention.

[0042] This application provides a method, system, device, and medium for automatically loading battery modules into a battery box, thereby improving the quality, stability, and safety of battery module loading.

[0043] The overall concept of the technical solution in this application embodiment is as follows: The PLC controls the PACK line and module line to transfer the box and battery module. The PLC performs glue application verification on the box and insulation strip verification and module type verification on the battery module. Then, the PLC controls the robot to pick up the battery module from the module station and take it to the cleaning station for plasma cleaning. The robot then picks up the cleaned battery module and performs automatic box loading operation. Compared with the traditional manual hoisting of battery modules into the box, this improves the quality, stability and safety of battery module loading into the box.

[0044] Example 1

[0045] This embodiment provides a method for automatically placing battery modules into a box, such as... Figure 1 As shown, it includes the following steps:

[0046] Step S10: The enclosure is transferred to the enclosure station via the PACK line, and the battery module is transferred to the module station via the module line.

[0047] In step S20, the PLC verifies the housing at the housing station and the battery module at the module station, respectively.

[0048] Step S30: The PLC controls the robot to grab the battery module from the module station to the cleaning station, and controls the plasma cleaner to perform plasma cleaning on the battery module at the cleaning station.

[0049] The cleaning station has three positions: cleaning, waiting to be loaded, and waiting to be unloaded, which can be switched by rotation. After the previous battery module is cleaned, the cleaning station rotates one position, and the battery module in the waiting to be loaded position moves to the cleaning position. At this time, the plasma cleaning head rises and moves according to the cleaning coordinates to clean the bottom of the battery module. After cleaning, the plasma cleaning head descends to its original position, the cleaning station rotates one position again, and the battery module moves to the waiting to be unloaded position. The cleaning station then enters the next cycle. The cleaned battery modules wait for the robot to grab them and put them into the box.

[0050] Step S40: The PLC-controlled robot picks up the cleaned battery modules and places them sequentially into the boxes at the box station. The boxes that have completed the boxing operation flow out along the PACK line.

[0051] This invention uses a PLC as the control center to build a control system. The module code of the battery module on the tray is obtained through the RFID reader on the module line. Based on the module code, the module pairing information is obtained. After verification, the battery module is picked up by a robot and taken to the cleaning station for plasma cleaning. After cleaning, the battery module is picked up by a robot and sorted into boxes at the box station.

[0052] Step S10 specifically involves:

[0053] The PLC determines the working status of the box assembly station and the module assembly station. When the working status is idle, it controls the PACK line to transfer the glued boxes to the box assembly station, and controls the module line to transfer the paired battery modules to the module assembly station in sequence via trays. The PACK line has a left box assembly station and a right box assembly station, which can perform the box loading operation of two boxes at the same time.

[0054] The module line receives paired battery modules from the front end. The paired battery modules are paired in pairs. The battery module types include M1, M2, M3, and M4. M1 and M2 are paired together, and M3 and M4 are paired together. Each box requires four battery modules from M1 to M4. Therefore, the module line needs two sets of battery modules per cycle. The incoming order of the battery modules has been completed by the buffer scheduling station at the front end. However, considering the possibility of scheduling errors or NG (not working) incoming materials, the module line's grabbing station still has a verification function. The RFID reader at the grabbing station reads the information of the tray to obtain the module code of the battery module, and then matches the module type. If it is an NG module or the module type is incorrect, the tray will be released directly. If the module type is correct, the station will be lifted to wait for grabbing.

[0055] Step S20 specifically involves:

[0056] The PLC reads the box code of the box at the box station through the RFID reader, matches the glue application data from the database with the box code, and checks whether the box is properly glued based on the glue application data. If yes, the box glue application verification is successful; otherwise, the box glue application verification fails.

[0057] The PLC uses a camera to visually identify the battery modules at the module station, determining whether the insulation strips of the battery modules are missing. If so, an alarm is triggered for missing insulation strips; otherwise, the following steps are taken:

[0058] The module code of the battery module at the module station is read by an RFID reader. The module type is matched with the module code from the database. It is determined whether the matched module type is consistent with the preset module type. If it is, the battery module verification is successful; otherwise, the battery module verification fails.

[0059] Step S40 specifically involves:

[0060] The PLC sets the order and position for each type of battery module to be placed in the box. The PLC controls the robot to use a camera to locate the cleaned battery modules, pick them up and move them to the top of the box. Then, the robot uses a camera to locate the box and places the battery modules into the corresponding positions in the box according to the order.

[0061] During the box-entry process, the PLC verifies the information of the battery module and the box multiple times. For example, the module line verifies the module type and determines the required battery module based on the previously read module type. At the same time, during the module grabbing process, the PLC calculates the grabbing position number of the battery module based on the flag bit and memory data, and performs double verification with the sensor to ensure the correct box entry position of the battery module. The box is also verified. Boxes with NG glue application will flow directly out of the NG outlet. The relevant data is connected to the MES system. By comparing the data, boxes with too long an interval between box entry and glue application will be judged as NG box entry and will also flow out of the NG outlet.

[0062] Example 2

[0063] This embodiment provides an automatic battery module loading system, such as... Figure 2 As shown, it includes the following modules:

[0064] The feeding module is used to transfer the housing to the housing station through the PACK line, and the battery module to the module station through the module line.

[0065] The enclosure and battery module verification module is used by the PLC to verify the enclosure at the enclosure station and the battery module at the module station respectively.

[0066] The battery module cleaning module is used by PLC to control the robot to pick up the battery modules from the module station and move them to the cleaning station, and control the plasma cleaner to perform plasma cleaning on the battery modules at the cleaning station.

[0067] The cleaning station has three positions: cleaning, waiting to be loaded, and waiting to be unloaded, which can be switched by rotation. After the previous battery module is cleaned, the cleaning station rotates one position, and the battery module in the waiting to be loaded position moves to the cleaning position. At this time, the plasma cleaning head rises and moves according to the cleaning coordinates to clean the bottom of the battery module. After cleaning, the plasma cleaning head descends to its original position, the cleaning station rotates one position again, and the battery module moves to the waiting to be unloaded position. The cleaning station then enters the next cycle. The cleaned battery modules wait for the robot to grab them and put them into the box.

[0068] The automatic box loading module is used by PLC-controlled robots to pick up the cleaned battery modules and place them sequentially into the boxes at the box loading station. The boxes that have completed the loading operation flow out along the PACK line.

[0069] This invention uses a PLC as the control center to build a control system. The module code of the battery module on the tray is obtained through the RFID reader on the module line. Based on the module code, the module pairing information is obtained. After verification, the battery module is picked up by a robot and taken to the cleaning station for plasma cleaning. After cleaning, the battery module is picked up by a robot and sorted into boxes at the box station.

[0070] The feeding module is specifically used for:

[0071] The PLC determines the working status of the box assembly station and the module assembly station. When the working status is idle, it controls the PACK line to transfer the glued boxes to the box assembly station, and controls the module line to transfer the paired battery modules to the module assembly station in sequence via trays. The PACK line has a left box assembly station and a right box assembly station, which can perform the box loading operation of two boxes at the same time.

[0072] The module line receives paired battery modules from the front end. The paired battery modules are paired in pairs. The battery module types include M1, M2, M3, and M4. M1 and M2 are paired together, and M3 and M4 are paired together. Each box requires four battery modules from M1 to M4. Therefore, the module line needs two sets of battery modules per cycle. The incoming order of the battery modules has been completed by the buffer scheduling station at the front end. However, considering the possibility of scheduling errors or NG (not working) incoming materials, the module line's grabbing station still has a verification function. The RFID reader at the grabbing station reads the information of the tray to obtain the module code of the battery module, and then matches the module type. If it is an NG module or the module type is incorrect, the tray will be released directly. If the module type is correct, the station will be lifted to wait for grabbing.

[0073] The housing and battery module verification module is specifically used for:

[0074] The PLC reads the box code of the box at the box station through the RFID reader, matches the glue application data from the database with the box code, and checks whether the box is properly glued based on the glue application data. If yes, the box glue application verification is successful; otherwise, the box glue application verification fails.

[0075] The PLC uses a camera to visually identify the battery modules at the module station, determining whether the insulation strips of the battery modules are missing. If so, an alarm is triggered for missing insulation strips; otherwise, the following steps are taken:

[0076] The module code of the battery module at the module station is read by an RFID reader. The module type is matched with the module code from the database. It is determined whether the matched module type is consistent with the preset module type. If it is, the battery module verification is successful; otherwise, the battery module verification fails.

The PLC controls the robot to use a camera to locate the cleaned battery modules, pick them up and move them to the top of the box.
