Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] This utility model embodiment is applicable to the scenario of processing battery cells in a battery pack module, taking a lithium battery pack as an example. This utility model provides a battery processing system with wireless device connectivity, achieving signal interaction between client communication modules through a server-side communication module to avoid extensive wiring. The embodiments of this utility model are described below with reference to the accompanying drawings.

[0025] According to embodiments of the present invention, in one aspect, a battery processing system with wireless device connectivity is provided, such as... Figure 1 As shown, the system includes: a device control module 100, each device control module 100 being connected to a corresponding industrial device 200, and each device control module 100 being equipped with a server communication module 300, a first client communication module 400, or a second client communication module 500; the server communication module 300 being wirelessly connected to the first client communication module 400 and the second client communication module 500, and being used to receive request signals sent by the first client communication module 400 and send the request signals to the second client communication module 500, and to receive completion signals sent by the second client communication module 500 and send the completion signals to the first client communication module 400; the first client communication module 400 being used to send the obtained request signals from the corresponding industrial device 200 to the server communication module 300 and to receive the completion signals sent by the server communication module 300; the second client communication module 500 being used to receive the request signals sent by the server communication module 300 and to send the obtained completion signals from the corresponding industrial device 200 to the server communication module 300.

[0026] Specifically, in this embodiment of the invention, the equipment control module 100 is a Programmable Logic Controller (PLC). A PLC is a controller for automated equipment that uses programming to perform logic control, timing, counting, and arithmetic operations. It is widely used in industrial automation, especially in manufacturing, to control machinery, production lines, and factory automation systems, and serves as the terminal for receiving and generating equipment signals. In this embodiment, the equipment control module 100 and the corresponding industrial equipment 200 are in relatively fixed positions and are therefore connected via wiring to control the industrial equipment or acquire relevant signals. This invention, by connecting the equipment control module and the corresponding industrial equipment via wiring, enables task control and signal acquisition of the industrial equipment, improving signal reliability.

[0027] In some optional embodiments, the equipment control module 100 of this utility model includes: a first equipment control module 101, a second equipment control module 102, a third equipment control module 103, and a fourth equipment control module 104. By setting multiple equipment control modules, different devices can be controlled to perform different tasks, thereby completing multiple processes through inter-device collaboration. Taking battery processing as an example, such as... Figure 2 As shown, the first device control module 101 corresponds to Figure 2 The PLC of Unit 1 corresponds to the second equipment control module 102. Figure 2 The PLC of the second machine corresponds to the third equipment control module 103. Figure 2 The PLC of Unit 3 corresponds to the fourth equipment control module 104. Figure 2 The fourth PLC is used in this process. More specifically, the first PLC is the feeding control module, used to transport unprocessed battery cells from the storage bin or hopper to the production line; the second PLC is the cutting control module, used to control the cutting machine to cut the unprocessed battery cells; the third PLC is the welding control module, used to control the welding machine to weld the cut battery cells; and the fourth PLC is the bending control module, used to control the bending machine to bend the welded battery cells according to characteristic angles or shapes. As can be seen, the first, second, third, and fourth PLCs correspond to different process flows, completing different processing flows by generating feeding request signals and feeding completion signals, achieving collaboration among various industrial devices, and ultimately completing the battery cell processing.

[0028] In some alternative implementations, to improve cell processing efficiency, multiple production lines can be set up simultaneously. That is, a single feeding control module feeds materials to different production lines, and each production line is sequentially equipped with a cutting control module, a welding control module, and a bending control module, such as... Figure 2As shown, PLC 1 is the feeding control module, PLCs 2, 3, and 4 correspond to one production line, and slave PLCs 1, 2, and 3 correspond to another production line. PLCs 2 and 1 are cutting control modules, PLCs 3 and 2 are welding control modules, and PLCs 4 and 3 are bending control modules. This is just an example and not a limitation. This utility model provides feeding for multiple production lines through one feeding control module. Each production line includes sequentially executed cutting, welding, and bending control modules, enabling efficient battery processing.

[0029] In some alternative implementations, such as Figure 2 As shown, in order to achieve wireless communication between devices, this embodiment of the invention provides each device control module 100 with an independent communication module, such as an ESP8266 module or an ESP32 module, which is equivalent to a signal conversion module and can convert the ordinary level signal of the pins into a WIFI signal. Its pin diagram is shown below. Figure 3 As shown. The ESP8266 and ESP32 modules are low-cost, high-performance wireless WiFi modules that integrate a WiFi chip and processor, providing stable wireless connectivity and strong processing capabilities. This invention utilizes ESP8266 or ESP32 modules to build a WiFi network, enabling wireless communication between devices while maintaining a smaller and lower-cost communication module. The PLC and ESP8266 physical I / O connection can use RS485 communication to acquire more data streams. Figure 4 As shown, the first port Y5 of the device control module 100 is connected to the signal receiving terminal GPIO5 of the corresponding communication module, and the second port X17 of the device control module 100 is connected to the signal transmitting terminal GPIO4 of the corresponding communication module. Thus, each device control module 100 can achieve both signal reception and signal transmission. This invention, through the connection of two pairs of ports between the device control module and the communication module, enables simultaneous signal reception and transmission, thereby achieving communication and interaction between two devices for signals such as material feeding requests and material feeding completion, and automating the cooperation between the devices.

[0030] In some optional implementations, during actual communication, the power signal of the communication module and the power signal of the device control module 100 may have inconsistent voltages. Therefore, this embodiment of the invention sets relays at the connection ports between the device control module 100 and the communication module to convert the signal voltage. For example, the power signal of the ESP8266 module is 3.3V, while the PLC signal source is generally 24V. This embodiment of the invention sets a first relay KA1 between the first port Y5 of the device control module 100 and the signal receiving port GPIO5 of the communication module, and a second relay KA2 between the second port X17 of the device control module 100 and the signal transmitting port GPIO4 of the communication module. This achieves signal voltage conversion, converting the signal output from GPIO5 into a signal usable on Y5 of the PLC, or converting the signal output from X17 of the PLC into a signal usable on GPIO4. By setting relays between ports, this invention can convert signals according to the performance of the module ports, thereby ensuring signal transmission between the device control module and the communication module.

[0031] In some optional implementations, to enable signal interaction between the device control modules 100, this embodiment of the invention sets the communication module of one device control module 100 as a server communication module 300, and the communication modules of the remaining device control modules 100 as client communication modules. This ensures that the first client communication module 400 and the second client communication module 500, which need to cooperate, can interact with each other based on the server communication module 300. During the cell processing, two devices corresponding to adjacent processes need to establish signal interactions such as feeding request and feeding completion to connect the two devices, thereby ensuring smooth processing. This invention uses the feeding control module as a server, enabling the relay of feeding request and feeding completion signals between clients such as the cutting control module, welding control module, and bending control module. This avoids extensive wiring on a single host device when multiple slave devices are connected.

[0032] In some alternative implementations, such as Figure 4As shown, the ESP8266 module has a working mode switch at pin GPIO14, which can switch the working mode of the ESP8266 module. When the switch changes, it can switch the AP server to STA client or vice versa as needed. Taking a production line as an example, this embodiment of the invention uses PLC No. 1 as the server and PLCs No. 2, No. 3, and No. 4 as clients. Communication between PLCs No. 2 and No. 3, and between PLCs No. 3 and No. 4, is achieved through PLC No. 1. Any two of PLCs No. 2, No. 3, and No. 4 will communicate in a fixed order, which is set according to the processing flow and is not limited here.

[0033] In some alternative implementations, such as Figure 5 As shown, the point-to-point wireless communication process between PLC 1 (server) and PLCs 2, 3, and 4 (client) is described as an example:

[0034] S1, Power on the device and initialize it, turn on the device-side PLC (PLC of machine 1, PLC of machine 2, PLC of machine 3, PLC of machine 4) and the ESP8266 module of each machine;

[0035] S2, the ESP8266 of the first unit is set to AP mode. Its function is to generate a Wi-Fi signal source to provide connections for other ESP8266 modules. As a server, it receives signals transmitted from other devices and sends them to the ESP8266 module with the specified IP.

[0036] S3, the ESP8266 modules on the PLCs of sub-devices No. 2, No. 3 and No. 4 connect to the ESP8266 module server of No. 1 through STA mode as clients. Its function is to establish a wireless network connection and communication between the ESP8266 modules on the sub-devices and the ESP8266 module of No. 1.

[0037] S4, the PLC of machine number two is connected to the ESP8266 module of machine number two through a line. Its function is to receive the feeding request signal of machine number three PLC, and after the industrial equipment corresponding to machine number two PLC completes the feeding, it sends the feeding completion signal to machine number three, thereby interacting with the signal of machine number three and cooperating with automation.

[0038] S5, the X17 and Y5 pins of the second PLC are connected to the GPIO4 and GPIO5 pins of the second ESP8266. By changing the level signal, the PLC signal of the second machine is transmitted to the ESP8266 module of the second machine.

[0039] S6, the ESP8266 module of machine 2 receives the feeding request signal from the ESP8266 module of machine 1 and corresponds it to GPIO5, or sends the feeding completion signal on GPIO4 to the ESP8266 module of machine 1 via WIFI and TCP protocol.

[0040] S7, X17 and Y5 of PLC No. 3 are connected to pins GPIO4 and GPIO5 on ESP8266 of No. 3. PLC No. 3 obtains feeding request signal and feeding completion signal by reading the level changes of GPIO4 and GPIO5 on ESP8266.

[0041] S8, the ESP8266 module of machine No. 3 maps the received feeding completion signal to the pin level change on the ESP8266;

[0042] S9, the ESP8266 module of machine No. 3 is connected to the ESP8266 module of machine No. 1 via WIFI. The ESP8266 module of machine No. 1 sends the feeding completion signal received from the ESP8266 module of machine No. 2 to the ESP8266 module of machine No. 3.

[0043] In some optional implementations, based on the aforementioned ESP8266 module's operating mode switch, if the PLC of machine number one malfunctions and cannot act as an AP server during battery processing, the operating mode switch of the ESP8266 module can be used to switch the PLC of machine number one to a STA client. Alternatively, one of the PLCs of machine number two, three, or four can be selected and switched to an AP server using the corresponding ESP8266 module's operating mode switch. The specific settings are determined based on the actual operating conditions and are not limited here. This invention, by setting an operating mode switch, enables switching between the server and client roles of the master or slave machine, thereby allowing for system layout based on equipment status without affecting the entire network. This avoids the situation where a master failure leads to system paralysis, improving the stability of the battery processing system.

[0044] In some optional implementations, different ESP8266 modules in this embodiment of the invention communicate wirelessly via WIFI based on the Transmission Control Protocol (TCP), which enables long-distance wireless signal transmission, avoids a large amount of wiring between devices, and allows the devices to be placed more flexibly without being limited by the physical length of the wires within a certain area.

[0045] In some optional implementations, this invention also pre-assigns a unique static IP address to each ESP8266 module, enabling automatic connection between ESP8266 modules based on the Wi-Fi search function. For example, ESP8266 module 1: 192.168.0.100, ESP8266 module 2: 192.168.1.101, ESP8266 module 3: 192.168.0.102, ESP8266 module 4: 192.168.1.103, and so on. This invention, by assigning static IP addresses to each device control module, enables automatic connection between devices based on static IP addresses, avoiding errors from manual wiring.

[0046] The battery processing system with wireless device connectivity provided in this embodiment connects to corresponding industrial equipment via a device control module. It acquires request or completion signals from the industrial equipment. The device control module is equipped with either a server-side communication module or a client-side communication module. The first client-side communication module receives the request signal and sends it to the server-side communication module. The server-side communication module receives the request signal and sends it to the second client-side communication module. The second client-side communication module receives the completion signal and sends it to the server-side communication module. The server-side communication module receives the completion signal and sends it to the first client-side communication module. This invention enables wireless interactive communication between different clients via a server. The wireless setup is simple. While ensuring automated collaboration between devices, client communication based on the TCP protocol in WIFI AP / STA mode enables wireless network connection between devices, eliminating the need for excessive communication line laying, reducing electrical installation requirements, and facilitating equipment relocation or movement within a certain range without affecting communication performance. Furthermore, wireless communication allows for the addition of slave devices as needed, ensuring the high efficiency and smooth operation of the battery processing system.
