Technical Field

[0001] This application relates to the field of automation control, and more specifically, to a method and a system for automation control in the field of automation control. Background Art

[0002] Currently, in the existing automation control technology, after a product completes all the process steps in a preset processing flow on a production line, the production line transports the product to a welding position, and then a welding machine performs the operation of the welding step on the product.

[0003] However, it is difficult to achieve automated control of the welding step in the existing automation control technology, which cannot meet the lean production requirements of modern manufacturing factories, and to a certain extent affects the production efficiency and quality of products. Summary of the Invention

[0004] This application provides a method and a system for automation control. The automation control system realizes the automated control of the welding machine through a manufacturing execution system / manufacturing operations management (MES / MOM) platform, a data acquisition device, an identification device, a controller, and a welding machine, effectively improving the production efficiency and quality of products.

[0005] In a first aspect, a method for automation control is provided, which is applied to an automation control system including a controller, a data acquisition device, an MES / MOM platform, an identification device, and a welding machine. The welding machine is connected to the controller, and the controller, the MES / MOM platform, and the identification device are respectively connected to the data acquisition device. The method includes:

[0006] The identification device identifies the product to obtain a product identifier;

[0007] The identification device sends the product identifier to the MES / MOM platform through the data acquisition device;

[0008] The MES / MOM platform generates a first instruction according to the product identifier, and the first instruction is used to indicate that all the process steps before the welding step of the product have been completed;

[0009] The MES / MOM platform sends the first instruction to the controller through the data acquisition device;

[0010] The controller sends a first start signal to the welding machine according to the first instruction;

[0011] The welding machine performs the operation of the welding process on the product according to the first start signal to obtain a welding result;

[0012] The data acquisition device sends the welding result from the welding machine to the MES / MOM platform.

[0013] In the method for automated control provided by the embodiments of the present application, after the identification device identifies the product, the identified product identifier is sent to the MES / MOM platform through the data acquisition device. The MES / MOM platform can know whether the product has completed all the process steps before the welding process through the product identifier. If the MES / MOM platform determines that the product has completed all the process steps before the welding process, it can send a first instruction to the controller through the data acquisition device. The controller can control the welding machine to weld the product according to the first instruction. After the welding machine completes the operation of the welding process, the data acquisition device sends the welding result to the MES / MOM platform. In the above solution, the MES / MOM platform can judge whether the product has completed all the process steps before the welding process according to the product identifier. After determining that the product has completed all the process steps before the welding process, the entire automated control system continues to execute the subsequent steps to finally complete the welding process, which can avoid affecting the quality of the product due to omission of the operation of a certain process step. Moreover, in the product inspection of the prior art, the product is inspected only after all the process steps including the welding process are completed. That is to say, it is only after all the process steps including the welding process are completed that the problem that the product may not have completed all the process steps before the welding process can be found, which greatly reduces the production efficiency. However, in the technical solution of the present application, only after determining that the product has completed all the process steps before the welding process, the entire automated control system continues to execute the subsequent steps to finally complete the welding process, and the problem that the product may not have completed all the process steps before the welding process can be found before the welding process. In this way, the product can be removed before the welding process, so that unnecessary welding processes are not required, effectively improving the production efficiency of the product. In summary, the embodiments of the present application can improve the production quality and efficiency of the product.

After determining that the product has completed all the process steps before the first process step, the entire automatic control system continues to execute the subsequent steps to finally complete the first process step, which can avoid affecting the product quality due to omission of the operation of a certain process step. Moreover, in the product detection of the prior art, the product is detected only after all the process steps of the product are completed. That is to say, the problem that the product may not have completed all the process steps before the first process step is found only after all the process steps are completed, which greatly reduces the production efficiency.

[0047] The following will describe the technical solutions in the present application in conjunction with the drawings.

[0048] The method for automated control provided by the embodiments of the present application can be applied to various automated control systems capable of welding. The automated control system includes multiple devices including a welding machine. Through the interaction between the devices, automated control of the welding process can be achieved, and various data in the welding process can be monitored, statistically analyzed, and processed. In addition, through the interaction between the devices, automated control of other process steps can also be achieved, and various data in other process steps can be monitored, statistically analyzed, and processed.

[0049] Figure 1 Shows a schematic architecture diagram of an automated control system applicable to the embodiments of the present application. Refer to Figure 1 , the automated control system includes an MES / MOM platform 110, a data acquisition device 120, an identification device 130, a controller 140, a welding machine 150, and a production line body 160.

[0050] Exemplarily, the data acquisition device 120 can be connected to the MES / MOM platform 110, the device 130, and the controller 140 by wired or wireless means. Optionally, the data acquisition device 120 can also be connected to the welding machine 150 by wired or wireless means. The controller 140 can be connected to the welding machine 150 by wired or wireless means. Optionally, it can also be connected to the production line body 160 by wired or wireless means.

[0051] MES / MOM Platform 110: The MES / MOM platform 110 is used to interact with the data acquisition device 120 and feedback relevant data to the data acquisition device 120. Exemplarily, the MES / MOM platform 110 can also display the relevant parameters of each process step and each device to the user, so that the user can understand these parameters in a timely manner and at any time.

[0052] Data Acquisition Device 120: It is used to collect the data of each device (such as the controller 140, the identification device 130, and the welding machine 150) and forward it to the MES / MOM platform, and is used to realize the communication between the MES / MOM platform 110 and other devices (such as the controller 140, the identification device 130, and the welding machine 150).

[0053] To facilitate the implementation of the above functions of the data acquisition device 120, the embodiment of the present application can design the data acquisition device 120 as a device including multiple small modules.

[0054] In some embodiments, the data acquisition device 120 may include a bus module, a MES / MOM platform interface module, an identification module, a controller read / write module, and a welding parameter acquisition module. Among them, the bus module is used to initialize the MES / MOM platform interface module, the identification module, the controller read / write module, and the welding parameter acquisition module, so that the MES / MOM platform interface module establishes a connection with the MES / MOM platform 110, the identification module establishes a connection with the identification device 130, the controller read / write module establishes a connection with the controller 140, and the welding parameter acquisition module establishes a connection with the welding machine 150; and, the bus module is also used to receive the instructions sent by each of the above four modules and send the received instructions to other modules, so that other modules communicate with the corresponding devices.

[0055] Identification Device 130: It is used to identify the product. Exemplarily, the identification device 130 is used to identify the product according to the product identification instruction sent by the data acquisition device 120 and return the identification result to the data acquisition device 120.

[0056] Controller 140: It is used to receive the instructions of each device (such as the data acquisition device 120, the welding machine 150, and the production line body 160), and send instructions to each device (such as the data acquisition device 120, the welding machine 150, and the production line body 160) to control each device to perform relevant actions.

[0057] Exemplarily, the controller 140 may have multiple built-in registers and multiple input / output (IO) ports. The controller 140 may receive instructions from the data acquisition device 120, the welding machine 150, the production line body 160, etc., change the state values of the built-in registers according to the instructions, and send instructions to the data acquisition device 120, the ultrasonic welding machine 150, the production line body 160, etc. according to the state values.

[0058] The welding machine 150: is used to receive the start signal sent by the controller 140, perform the operations of the welding process after receiving the start signal of the controller 140, and send the welding results to the MES / MOM platform 110 through the data acquisition device 120.

[0059] The welding machine 150 in the embodiment of the present application may be various forms of welding machines, and no limitation is made here. For example, the welding machine 150 may be an ultrasonic welding machine, a laser welding machine, a laser welding machine.

[0060] The production line body 160: may at least include machines, sensors, and signal lines, and is used to complete each process link required by the product. In implementation, the production line body 160 may interact with the controller 140, and the controller 140 controls each process link of the production line body 160.

[0061] In the automated control system of the embodiment of the present application, exemplarily, the automated control system may include multiple welding machines 150 and multiple identification devices 130. In this way, simultaneous operations of multiple products can be realized, and the operation efficiency can be further improved. For example, the automated control system may include 3 welding machines 150 and 3 identification devices 130. One welding machine 150 and one identification device 130 correspond to one product. In this way, within the same time period, the operations of 3 products can be carried out simultaneously, and the operation efficiency is higher.

[0062] It should be understood that the automated control system of the embodiment of the present application can be applied to the automated control process of various products. Exemplarily, the product may be a charging adapter, a wireless charger, a power adapter, etc.

[0063] It should also be understood that Figure 1 The automated control system shown in

[0064] Existing automated control technologies are difficult to achieve automated control of the welding process, unable to meet the lean production requirements of modern manufacturing plants, and have a greater impact on the production efficiency and quality of products. To solve the problems existing in the existing automated control technologies, this application proposes a method of automated control. After the identification device identifies the product, the MES / MOM platform can determine whether the product has completed all the process steps before the welding process based on the identification mark. If the product has completed all the process steps before the welding process, the entire automated control system will continue to execute the subsequent steps to finally complete the welding process. In this way, it is possible to avoid affecting the quality of the product due to the omission of the operation of a certain process step; moreover, it is possible to discover before the welding process that the product may not have completed all the process steps before the welding process. In this way, the product can be removed before the welding process, so that unnecessary welding processes do not need to be carried out, effectively improving the production efficiency of the product. In summary, the embodiments of this application can improve the production quality and efficiency of products.

[0065] Figure 2 FIG. shows a schematic flowchart of a method 200 for automated control provided by an embodiment of this application. The method 200 can be applied to Figure 1 the automated control system shown. In the automated control system, the MES / MOM platform, data acquisition device, identification device, controller, welding machine, and production line body in the automated control system can respectively correspond to Figure 1 the MES / MOM platform 110, data acquisition device 120, identification device 130, controller 140, welding machine 150, and production line body 160. Hereinafter, each step of the method 200 will be described in detail.

[0066] In S210, the identification device identifies the product to obtain a product identifier.

[0067] The product identifier is used to identify the product and distinguish each product from other products. It should be understood that each product has a unique identifier, and there is a one-to-one correspondence between the product identifier and the product.

[0068] Exemplarily, the product identifier can be a product identity document (ID). For example, the product ID is 001. When the product ID is 001, consumers and staff can correspond to a unique product according to 001.

[0069] In some embodiments, the identification device can be a barcode device. Correspondingly, a barcode is set on the product. In implementation, the identification device obtains the product identifier by identifying the barcode of the product. Exemplarily, the barcode can be a one-dimensional barcode or a two-dimensional barcode, and no limitation is made here.

[0070] In S220, the identification device sends the product identification to the MES / MOM platform through the data acquisition device.

[0071] In the automated control system, the identification device is connected to the MES / MOM platform through the data acquisition device. That is, the identification device is connected to the data acquisition device, and the data acquisition device is connected to the MES / MOM platform. Therefore, in this step, the identification device sends the product identification to the data acquisition device, and the data acquisition device sends the product identification to the MES / MOM platform.

[0072] Exemplarily, after the identification device identifies the product, it obtains the product identification of the product, sends the product identification to the identification module in the data acquisition device, and the bus module of the data acquisition device calls the MES / MOM platform interface module to send the product identification from the identification device to the MES / MOM platform.

[0073] In S230, the MES / MOM platform generates a first instruction according to the product identification, and the first instruction is used to indicate that all process steps before the welding step of the product have been completed.

[0074] The data of each process step before the welding step of the product is stored in the MES / MOM platform, and there is a corresponding relationship between the product identification and the product data. For a product, the MES / MOM platform can obtain the product data from the corresponding relationship between the received product identification and the product data stored, and judge whether all process steps before the welding step of the product are completed.

[0075] If all process steps before the welding step of the product are completed, the MES / MOM platform will generate a first instruction and continue to execute step S240.

[0076] If all process steps before the welding step of the product are not completed, the MES / MOM platform can generate a negative instruction, and the negative instruction is used to indicate that all process steps before the welding step of the product are not completed. The MES / MOM platform sends the negative instruction to the data acquisition device. The MES / MOM platform interface module of the data acquisition device receives the negative instruction, and the bus module of the data acquisition device calls the controller read / write module to write the NG value of 2 into the register R3 of the controller. When the value written into R3 of the controller is the NG value of 2, the controller can send a high-level signal to the production line body through the IO output port Y2, indicating that the operation of all process steps before the welding step of the product is not completed, and removing the product from the welding step.

[0077] In S240, the MES / MOM platform sends the first instruction to the controller through the data acquisition device.

[0078] In an automated control system, the MES / MOM platform is connected to the controller through a data acquisition device. That is, the MES / MOM platform is connected to the data acquisition device, and the data acquisition device is connected to the controller. Therefore, in this step, when the MES / MOM platform sends a first instruction to the controller, it can send the first instruction to the data acquisition device, and the data acquisition device sends the first instruction to the controller.

[0079] Exemplarily, the MES / MOM platform sends a first instruction to the MES / MOM platform interface module in the data acquisition device. After the MES / MOM platform interface module in the data acquisition device receives the first instruction, the bus module in the data acquisition device calls the controller read / write module to write an OK value of 1 to the register R3. The OK value of 1 written to the register R3 is used to indicate that the MES / MOM platform has completed all process steps before the welding process for the product according to the judgment result of the product identification.

[0080] In S250, the controller sends a first start signal to the welding machine according to the first instruction.

[0081] It should be understood that the first start signal is a signal used to indicate that the welding machine can perform the operations in the welding process.

[0082] The controller receives the first instruction and knows for sure that the product has completed the operations of all process steps before the welding process. Therefore, it can perform the operations in the welding process. Thus, after receiving the first instruction, the controller sends a first start signal to the welding machine.

[0083] Exemplarily, the controller writes an OK value of 1 to the register R3 of the controller according to the received first instruction. When the value written to R3 of the controller is the OK value of 1, the controller can send a high-level signal to the welding machine through the IO output port Y3, indicating that the product has completed the operations of all process steps before the welding process and can perform the welding operation.

[0084] Generally, before the welding machine performs the operations in the welding process on the product, it is necessary to perform an enclosure operation on the product. After the enclosure operation is completed, it means that the product is in a position where it can be welded. In this way, the welding machine can perform the operations in the welding process. Therefore, in S250, the embodiment of the present application can control the production line body to perform the enclosure operation through the controller, and then control the welding machine to perform the operations in the welding process.

[0085] In some embodiments, the controller sends the first instruction to the production line body; the controller receives the enclosure operation instruction sent by the production line body based on the first instruction, and the enclosure operation instruction is used to indicate that the production line body completes the enclosure operation; the controller sends a first start signal to the welding machine according to the enclosure operation instruction.

[0086] In this embodiment, the controller sends a first instruction to the production line body. After receiving the first instruction, the production line body performs an enclosure operation on the product. After the production line body completes the enclosure operation, it generates an enclosure operation instruction and sends the enclosure operation instruction to the controller. The controller sends a first start signal to the welding machine according to the enclosure operation instruction.

[0087] Exemplarily, after receiving the first instruction, the controller can send a high-level signal to the production line body through the IO output port Y1, indicating that the enclosure operation can be performed on the product. The meaning of the enclosure operation is to accurately position the product at the welding position of the welding machine. After the production line body completes the enclosure operation on the product, it sends a high-level signal to the controller through the IO input port X1. After the controller receives the high-level signal sent by the production line body through the IO input port X1, it can send a high-level signal to the welding machine through the IO output port Y3 to notify the welding machine to start the operation of the welding link.

[0088] In S260, the welding machine performs the operation of the welding link on the product according to the first start signal to obtain a welding result.

[0089] The welding result is various data generated in the welding machine related to the operation of the welding link after the welding machine performs the operation of the welding link on the product, and no specific limitation is made here. For example, the welding result may include the welding parameter information of the welding process, or the welding result may include information indicating whether the welding machine has successfully completed the welding link.

[0090] In S270, the data acquisition device sends the welding result from the welding machine to the MES / MOM platform.

[0091] In this step, the data acquisition device receives the welding result from the welding machine and sends the welding machine result to the MES / MOM platform.

[0092] It should be understood that the data acquisition device can obtain the welding result in various ways. For example, the data acquisition device directly obtains the welding result from the welding machine, and no specific limitation is made here. Specific descriptions will be given below.

[0093] The method of automatic control provided by the embodiments of the present application is applied to an automatic control system including a controller, a data acquisition device, an MES / MOM platform, an identification device, and a welding machine. The data acquisition device is connected to the MES / MOM platform, the identification device, and the controller, and the controller is connected to the welding machine. After the identification device identifies the product, it sends the identified product identifier to the MES / MOM platform through the data acquisition device. The MES / MOM platform can know whether the product has completed all the process steps before the welding step through the product identifier. If the MES / MOM platform determines that the product has completed all the process steps before the welding step, it can send a first instruction to the controller through the data acquisition device. The controller can control the welding machine to weld the product according to the first instruction. After the welding machine completes the operation of the welding step, the data acquisition device sends the welding result to the MES / MOM platform. In the above solution, the MES / MOM platform can judge whether the product has completed all the process steps before the welding step according to the product identifier. After determining that the product has completed all the process steps before the welding step, the entire automatic control system continues to execute the subsequent steps to finally complete the welding step, which can avoid affecting the quality of the product due to missing the operation of a certain process step. Moreover, in the product inspection of the prior art, the product is inspected only after all the process steps including the welding step are completed. That is to say, the problem that the product may not have completed all the process steps before the welding step will be found only after all the process steps including the welding step are completed, which greatly reduces the production efficiency. However, in the technical solution of the present application, only after determining that the product has completed all the process steps before the welding step, the entire automatic control system continues to execute the subsequent steps to finally complete the welding step, and the problem that the product may not have completed all the process steps before the welding step can be found before the welding step. In this way, the product can be removed before the welding step, so that unnecessary welding steps are not required, effectively improving the production efficiency of the product. In summary, the embodiments of the present application can improve the production quality and efficiency of the product.

[0094] As described above, the welding result includes various data related to the operation of the welding step. Next, the content of the welding result will be specifically described.

[0095] In some embodiments, the welding result may include welding parameter information, which is used to indicate the actual values of the welding parameters of the welding machine when the welding machine welds the product. Exemplarily, the actual values of the welding parameters may be the real-time values of the welding parameters when the welding machine welds the product, and the real-time values may include the values of the welding parameters at different times.

[0096] Exemplarily, the actual value of the welding parameter can be the average value of the welding parameters when the welding machine welds the product, and this average value can be obtained based on the values of the welding parameters at different times.

[0097] Exemplarily, the welding parameter can include any one of the following: frequency, amplitude, pressure, power, energy, and the working time of the welding process. It should be understood that the welding parameter can also include more other parameters, and no limitation is made here.

[0098] In the embodiments of the present application, the data acquisition device can obtain the welding parameter information in the following manner.

[0099] Before the data acquisition device sends the welding result from the welding machine to the MES / MOM platform, the method further includes: the welding machine sends the welding parameter information to the data acquisition device.

[0100] Exemplarily, after completing the operation of the welding process, the welding machine directly sends the welding parameter information to the welding parameter acquisition module of the data acquisition device, and the welding parameter acquisition module of the data acquisition device performs standard formatting processing on the welding parameter information, and the bus module of the data acquisition device sends the welding parameter information to the MES / MOM platform through the MES / MOM platform interface module.

[0101] In the method of automatic control provided by the embodiments of the present application, the welding result received by the MES / MOM platform includes the welding parameter information, which can enable the staff to analyze the welding parameter information, and then determine the areas that need to be further optimized for the welding machine according to the analysis result (for example, modifying the preset values of some welding parameters), so as to improve the speed and quality when the welding machine welds the product, and improve the production quality and efficiency of the product.

[0102] In some other embodiments, the welding result can further include a first piece of information, and the first piece of information is used to indicate whether the welding machine has successfully completed the welding process.

[0103] It should be understood that the first piece of information can be a signal indicating successful completion of the welding process, or a signal indicating unsuccessful completion of the welding process.

[0104] In the embodiments of the present application, the data acquisition device can obtain the first piece of information in the following manner.

[0105] In one example, as described above, before the data acquisition device sends the welding result from the welding machine to the MES / MOM platform, the method further includes: the welding machine sends the first piece of information to the controller; the data acquisition device obtains the first piece of information from the controller. It should be noted that when the data acquisition device obtains the first piece of information from the controller, it can obtain the first piece of information regularly. For example, the data acquisition device obtains the first piece of information from the controller every 100 milliseconds.

[0106] When the first information is used to indicate that the welding machine has successfully completed the operation of the welding link, after completing the operation of the welding link, the welding machine sends a high-level signal to the controller through the IO input port X2, assigns the controller's register R5 to the completion value of 1, and assigns the register R6 to the OK value of 1. When the controller read-write module of the data acquisition device obtains the register R5 value of 1 and the status value of register R6, it sends the welding link operation completion OK event to the bus module. The controller sends a high-level signal to the production line through the IO output port Y4 to send a generation completion signal, and sends a high-level signal to the production line through the IO output port Y5 to send a production OK signal to the production line. The production line executes production encirclement release and removes products to the good product area according to the IO output port Y4 and the IO output port Y5; when the bus module of the data acquisition device obtains the completion OK event notification sent by the controller read-write module, the data acquisition device synchronously receives the first information sent by the welding machine. The welding results including the first information are sent to the MES / MOM platform through the MES / MOM platform interface module.

[0107] When the first information is used to indicate that the welding machine has not successfully completed the operation of the welding link, after completing the operation of the welding link, the welding machine sends a high-level signal to the controller through the IO input port X3, assigns the controller's register R5 to 1, and assigns the register R6 to the NG value of 2. When the controller read-write module of the data acquisition device obtains the value of register R5 to be 1 and the status value of register R6, it sends the welding link operation completion NG event to the bus module. The controller sends a high-level signal to the production line through the IO output port Y4 to send a generation completion signal, and sends a high-level signal to the production line through the IO output port Y6 to send a production NG signal to the production line. The production line executes production encirclement release and removes products to the bad area according to the IO output port Y4 and the IO output port Y6; when the bus module of the data acquisition device obtains the completion NG event notification sent by the controller read-write module, the data acquisition device synchronously receives the first information sent by the welding machine. The welding results including the first information are sent to the MES / MOM platform through the MES / MOM platform interface module.

[0108] The automated control method provided in the present application includes first information indicating whether the welding machine has successfully completed the welding process in the welding results received by the MES / MOM platform, so that the staff can judge at which values ​​the welding parameters of the welding machine are set under various preset welding parameters based on the first information, so as to achieve a higher yield rate in the welding process, thereby improving the production quality and efficiency of the product.

[0109] In other embodiments, the welding result may also include welding parameter information and the first information.

[0110] Exemplarily, after the welding machine completes the welding operation, it sends the first information to the controller. The data acquisition device obtains the first information from the welding machine in the controller, and the welding machine sends the welding parameter information to the data acquisition device. Thus, the data acquisition device obtains the welding result including the welding parameter information and the first information. The specific steps are as described above and will not be elaborated here.

[0111] For the automated control method provided in this application, after the welding machine completes the welding operation, the MES / MOM platform can receive the welding result, and can perform combined analysis or independent analysis on the welding parameter information and the first information included in the welding result according to actual needs to determine whether it is necessary to optimize the welding machine by resetting the welding parameters, thereby improving the production quality and efficiency of the product.

[0112] It should be understood that the embodiments of this application do not limit the content included in the welding result. The welding parameter information and the first information included in the above welding result are only illustrative explanations and should not constitute a limitation to the embodiments of this application.

[0113] The automated control method provided in this application can preset the welding parameters of the welding machine according to actual needs before the MES / MOM platform obtains the welding result.

[0114] In some embodiments, preset values of the welding parameters for the welding operation are set in the MES / MOM platform. Exemplarily, the welding parameters may include at least one of the following: frequency, amplitude, pressure, power, energy, and the working time of the welding operation.

[0115] In some embodiments, before the identification device identifies the product to obtain the product identifier, the welding parameters of the welding machine can be set through the MES / MOM platform. For example, the staff can set the frequency of the welding machine to 20000 Hz, the amplitude to 80 μm, the pressure to 0.6 MPa, the power to 1300 W, the energy to 80 J, and the working time of the welding operation to 0.8 s through buttons or a touch interface. The MES / MOM platform interface module of the data acquisition device sends the set parameters to the MES / MOM platform interface module of the data acquisition device. The bus module of the data acquisition device sends the welding parameters received by the MES / MOM platform interface module to the welding machine through the controller, and the welding machine welds the product according to the received welding parameters to obtain the welding result.

[0116] For the automated control method provided in the embodiments of this application, the staff sets the welding parameters of the welding machine through the MES / MOM platform. Thus, it is not necessary for the staff to specifically set the welding parameters on the welding machine, which can improve the work efficiency and user experience of the staff.

[0117] Before the step of the recognition device recognizing the product in S210 above, the embodiments of the present application may trigger the recognition device to recognize the product in the following manner.

[0118] In some embodiments, before S210, method 200 may further include:

[0119] The production line body sends a scanning in-place instruction to the data acquisition device through the controller, and the scanning in-place instruction is used to indicate that the product has reached the scanning position; the data acquisition device sends a product recognition instruction to the recognition device according to the scanning in-place instruction, and the product recognition instruction is used to indicate the recognition device to recognize the product.

[0120] In this way, the recognition device recognizes the product after receiving the product recognition instruction to obtain the product identification.

[0121] Exemplarily, when the sensor of the production line body senses that the product has reached the scanning in-place position, the production line body outputs a high-level signal to the controller through the scanning in-place signal line. The scanning in-place position may be the position where the recognition device recognizes the product; after receiving the high-level signal, the controller assigns the value of register R1 corresponding to the scanning in-place signal to the OK value of 1. When the value of register R1 is the OK value of 1, it is used to indicate that the product has reached the scanning in-place position. The data acquisition device obtains the value of the built-in register R1 in the controller through the controller read-write module. When the value of register R1 is the OK value of 1, the controller read-write module sends a scanning in-place event notification to the bus module, and the bus module calls the recognition module to send a product recognition instruction to the recognition device. The product recognition instruction is used to indicate the recognition device to recognize the product, and the recognition device recognizes the product after receiving the product recognition instruction to obtain the product identification.

[0122] In the above automation control system, the automation control system can not only execute the welding process, but also execute other process steps, which are not limited in the embodiments of the present application.

[0123] In some embodiments, before the identification device identifies the product to obtain the product identifier, or, after the data acquisition device sends the welding result from the welding machine to the MES / MOM platform, the method may further include: the identification device identifies the product to obtain the product identifier; the identification device sends the product identifier to the MES / MOM platform through the data acquisition device; the MES / MOM platform generates a second instruction according to the product identifier, and the second instruction is used to indicate that all the process steps before the first process step of the product have been completed; the MES / MOM platform sends the second instruction to the controller through the data acquisition device; the controller sends a second start signal to the production line body according to the second instruction; the production line body performs the operation of the first process step on the product according to the second start signal to obtain the process result of the first process step; the data acquisition device sends the process result of the first process step from the production line body to the MES / MOM platform.

[0124] It should be understood that the first process step is any process step other than the welding step among all the process steps of the product. That is, the first process step may be a process step before the welding step or a process step after the welding step.

[0125] Exemplarily, the first process step may be a plug-in step or an assembly step.

[0126] Exemplarily, the process step before the welding step may be a plug-in step, and the process step after the welding step may be an automatic control laser engraving and coding step.

[0127] The automated control method provided by this application can, based on the principle of the completion of the above-described first process step, complete one or more process steps before the welding step, or complete one or more process steps after the welding step. In the above solution, the MES / MOM platform can determine whether the product has completed all the process steps before the first process step according to the product identification. After determining that the product has completed all the process steps before the first process step, the entire automated control system will continue to execute the subsequent steps to finally complete the first process step, which can avoid affecting the product quality due to the omission of the operation of a certain process step. Moreover, in the product inspection of the prior art, the product is inspected only after all the process steps of the product are completed. That is to say, the problem that the product may not have completed all the process steps before the first process step will be discovered only after all the process steps are completed, which greatly reduces the production efficiency. However, in the technical solution of this application, only after determining that the product has completed all the process steps before the first process step, the entire automated control system will continue to execute the subsequent steps to finally complete the first process step, and the problem that the product may not have completed all the process steps before the first process step can be discovered before the first process step. In this way, this product can be removed before the first process step, so that unnecessary first process steps do not need to be carried out, effectively improving the production efficiency of the product. In summary, the embodiments of this application can improve the production quality and efficiency of the product.

[0128] The automated control system of this embodiment can include more or fewer devices, and this application does not make any limitations. For example, the automated control system can include more (such as 4, 5, etc.) or fewer (such as 1, 2, etc.) welding machines, and more (such as 4, 5, etc.) or fewer (such as 1, 2, etc.) identification devices.

[0129] When the automated control system includes multiple welding machines and multiple identification devices, the MES / MOM platform, the data acquisition device, the identification device, the controller, and the welding machine can cooperate with each other for multi-channel operation, and each channel is independent of each other and does not affect each other.

[0130] Exemplarily, an automated control system includes an MES / MOM platform, a data acquisition device, three identification devices, a controller, and three welding machines. Each of the three identification devices corresponds to a position for identifying products, and each of the three welding machines corresponds to a position for performing welding operations on products. For example, when three products simultaneously arrive at the three positions for product identification by the three identification devices, the identification devices can independently complete the identification of the products to obtain product identifiers, and send the product identifiers to the MES / MOM platform through the data acquisition device. The MES / MOM platform determines whether the products corresponding to the three product identifiers have completed the operations of the process steps according to the preset process flow. If the operations of the process steps of the preset process flow have been completed, the MES / MOM platform sends instructions corresponding to the three products to the controller through the data acquisition device. The controller respectively controls the three products according to the three received instructions, so that the production line body completes the operations of the process steps corresponding to the three products. After the production line body completes the operations of the process steps corresponding to the three products, it sends the process results of the three products to the controller. After the data acquisition device obtains the process results of the process steps, it sends the process results of the process steps to the MES / MOM platform, thereby realizing multi-channel operations of automated control.
