Description

Technical Field

[0001] The present invention belongs to the technical field of solar cell wafers, and particularly relates to a safety label system for the production management of cell wafers. Background Art

[0002] During the production process of cell wafers, even products of the same batch have differences in terms of color, appearance, efficiency, open-circuit voltage, etc. Moreover, different customers have different requirements for cell wafer parameters. Therefore, cell wafers of the same batch may need to be labeled with different customers' labels.

[0003] The label system in the prior art is a stand-alone system. During the daily production operations on the production line, situations such as power outages, shutdowns, and restarts of the label system frequently occur. At this time, relevant label parameters need to be manually input. Also, since the label systems and label templates made for different customers in the label system are different, when there are cell wafers with different parameters in the same production batch, it is necessary to switch back and forth between different customers' label systems, and each time the label system is switched, relevant parameters also need to be manually input, which greatly affects the production efficiency and poses a relatively severe test to the operation ability of grass-roots workers. The labor cost that the enterprise needs to pay also increases accordingly. Moreover, due to the limited cognitive ability of grass-roots workers, once a label is incorrect, it is easy to cause the labels of one or even multiple batches of cell wafer products to be incorrect labels, which is time-consuming and laborious and affects the production process.

[0004] When a group has multiple production bases, since the label system in the prior art is a stand-alone independent system and there is no coordination between bases, when the same customer purchases a large quantity of cell wafers, the label serial numbers start printing from the starting number, resulting in overlapping ranges of some label serial numbers for the products received by the customer, and they cannot be warehoused, which in turn leads to situations such as customer complaints and order cancellations, bringing greater economic losses to the group.

[0005] Since the label system in the prior art is an independent system and cannot reasonably allocate the production capacity of each base, due to the level of grass-roots workers or incorrect command from the base leaders in each production base of the group, situations where a certain production base overproduces or underproduces often occur, which in turn brings unnecessary losses to the group. Also, due to the independence of the label systems of each production base, the controllability of the group over each production base is weak, increasing the risk of the group's assets.

[0006] The label system in the prior art does not adopt a distributed system setting mode. There is usually a long distance between the group and each production base. In the traditionally adopted mode where the group directly remotely controls the label systems of each production base, when sudden situations such as power outages and network disconnections occur, it is easy to affect the production progress of that base, thus disrupting the overall production plan of the group. Also, when the group needs to obtain the production data of each base, it is necessary for a special person to go to each base to obtain the corresponding data, which is time-consuming and laborious and increases the statistical cost.

[0007] For the label system itself, the amount of information carried by the label systems in the prior art is relatively small, and the information that can be found through the system is scarce.

[0008] Therefore, in view of the above technical problems, it is necessary to provide a security label system for the production management of solar cells. Summary of the Invention

[0032] The present invention will be described in detail below in conjunction with the embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional transformation made by those of ordinary skill in the art based on these embodiments is included in the protection scope of the present invention.

[0033] A safety label system for battery cell production management disclosed in an embodiment of the present invention, referring to Figure 1 、 3 shown, includes a main interface module, a total control module, a plurality of sub-control modules, and a plurality of terminal modules. The main interface module, the total control module, the plurality of sub-control modules, and the plurality of terminal modules are sequentially connected by signals, and each sub-control module is connected to at least one terminal module;

[0034] The main interface module includes a customer management unit, a label metadata configuration unit, a terminal management unit, a data analysis and statistics unit, and a permission management unit.

[0035] The operation status of the main interface module is as follows:

[0036] The customer management unit is used to input customer and / or order information. The customer information includes but is not limited to basic customer information and the battery cell parameter information required for the customer's previous orders. The order information includes but is not limited to the quantity of battery cells required by the customer this time and the battery cell parameters required. The customer management unit can store all the specific parameter-related materials of customers and the battery cells required by customers into this system, playing a leading role in the later production of battery cells, enabling targeted production at each production base, reducing inventory, and saving production capacity.

[0037] The label metadata configuration unit is used to statistically organize the label templates of each customer. According to the production capacity of each production base, it reasonably distributes the demand of a certain order to each production base in the form of label serial number segments through the label metadata configuration unit, so that the product labels obtained by customers will not appear duplicate, facilitating customers to store the products in the warehouse. At the same time, it can also shorten the delivery time and improve customer service efficiency.

[0038] The terminal management unit is used to directly manage each terminal module, and can monitor the online status of each terminal module at any time. According to the online status, it decides to perform operations such as adding, modifying, upgrading, disabling, and halting production on each relevant unit in the terminal module, facilitating the group's control over each production base and / or each production line, reducing the possibility of self-production by each production base and / or each production line, and further reducing the risk of the group's asset disposal.

[0039] The data analysis and statistics unit is used for the statistics and expression of all production data. The data analysis and statistics unit will real-time statistically count the production capacity status of each production base, facilitating the statistics of the production capacity of each base within a certain counting period, used to measure the work performance of each production base, and then analyze the production efficiency of each base within a certain period of time, summarize the possible reasons for low efficiency, and finally

[0040] Feedback to the manager in a concise and clear way such as forming charts, and feedback the corresponding data to the label metadata configuration unit, so that the label metadata configuration unit comprehensively considers the above factors when allocating the next production task and reallocates the task indicators.

[0041] The permission management unit is used for the management of the permissions of different work roles. It manages the permissions of different work roles, grades the permissions within each role, and makes the operation permissions increase gradually. This system can be applied to every link of production activities, ensuring the uniqueness of information obtained in each link, strengthening the accuracy of information control from order to delivery. Since the permissions of each role and each level within each role are different, it also improves the management of the group's business secrets.

[0042] The work roles include business roles, administrator roles, production worker roles, and quality inspector roles.

[0043] This system can be installed at different input terminals for each job role, and then logged in using an account password. The administrator sets the account permissions according to different job roles. Moreover, the business personnel role, administrator role, production worker role, and quality inspector role are also divided into different levels: level 1, level 2, level 3, etc. The operation permissions for different levels are different, and the operation permissions increase gradually.

[0044] When a businessperson receives a customer order, they log in to this system by entering their personal account password at the personal input terminal and enter the order information and customer information into the customer management unit.

[0045] When the administrator role logs in to their personal account, the customer and order information entered by the business role will be displayed. Then, according to the production capacity of each production base, the order quantity will be allocated to each production base from this system. Thus, the labels of this customer order obtained by each production base are different segment labels under the same customer label system, which reduces the situation of label duplication and customers being unable to be warehoused.

[0046] The production worker role is operated by each staff member on the production line. The tasks of this role in this system are relatively few. They only need to supervise and paste the labels printed by the label printing unit in the terminal module. When other situations occur, the production worker role needs to report in a timely manner.

[0047] The quality inspector role needs to retrieve the corresponding data within a certain counting cycle and analyze the relevant parameters. The quality inspector can also retrieve the required data at any time.

[0048] The operating status of the total control module is as follows:

[0049] The total control module includes an information distribution unit, a first information feedback unit, and a first database unit.

[0050] The information distribution unit receives and identifies the customer order information that has been allocated according to the production capacity and production line category of each production base sent by the label metadata configuration unit, and then distributes the production output required for each production base to the sub-control module of the corresponding production base and finally transmits it to the terminal module.

[0051] The first information feedback unit is used to send the information transmitted by the second information feedback unit to the main interface module, that is, the information is transmitted from the terminal module through the second information feedback unit and the first information feedback unit to the main interface module. The information transmitted back by the terminal module includes but is not limited to production base information, production line information, cell efficiency, cell color, and cell open circuit voltage, etc.

[0052] The first database unit is used to store records of all transaction information in this system, including but not limited to all tags and production information. The cloud server and the local server are both signal-connected to the second database unit and the first database unit, and information is shared among the cloud server, the local server, the second database unit, and the first database unit.

[0053] The operating status of the sub-control module is as follows:

[0054] The sub-control module includes a printing instruction unit, a second information feedback unit, and a second database unit.

[0055] After receiving the customer order information transmitted from the main control module, the sub-control module sends and records a printing instruction to the terminal module through the printing instruction unit.

[0056] The sub-control module is set up to transfer, record, and share some tasks of the main control module. The group and each production base are often far apart. In the existing technology, the mode of the main control module directly remotely controlling each production base is prone to network delay. And along the route of laying the lines connecting the main control module and each production base, the lines may be dug up for various reasons. The distributed system setup mode adopted by this system can not only prevent power outages and network disconnections from affecting the operations of the group on each production base, but also avoid network delays when the main control module of the group directly signal-connects to the terminal modules of each production base.

[0057] The printing instruction unit is used to send and record a printing instruction, that is, after receiving the information sent from the main control module, it distributes it to the terminal modules of each production line in this production base through the printing instruction unit.

[0058] The second information feedback unit is used to send the information feedback from the terminal module to the first information feedback unit, that is, the information is transmitted from the terminal module through the second information feedback unit and the first information feedback unit to the main interface module;

[0059] The second database unit is used to store records of all transaction information in this system, including but not limited to all tags and production information. The cloud server and the local server are both signal-connected to the second database unit and the first database unit, and information is shared among the cloud server, the local server, the second database unit, and the first database unit.

[0060] The operating status of the terminal module is as follows:

[0061] The terminal module includes a solar cell parameter detection unit and a label printing unit.

[0062] The terminal module receives the printing instruction sent by the printing instruction unit and starts the label printing unit for printing; the solar cell parameter detection unit can detect the actual parameters of the solar cells. For the solar cell products produced in the same batch, there are differences in solar cell efficiency, solar cell color, solar cell open-circuit voltage, etc. The solar cell parameter detection unit can specifically detect each solar cell, and then match the solar cell parameter information required by the customer sent by the main interface module. After a certain number of matched solar cells are accumulated, they will be packed and labeled with the printed label.

[0063] The terminal module reads the parameters of each solar cell through the sorter, classifies and counts the solar cells with different parameters. When the number of solar cells with each parameter accumulates to 120 pieces, the terminal module will feedback the solar cell parameter information to the industrial control computer through the PLC. The industrial control computer sends a printing request to the first instruction module and / or the printing instruction unit. The first instruction module and / or the printing instruction unit send this information back to the main interface module to match the entered customer information and order information. When the corresponding customer information is found, it means that the solar cell parameters are qualified and meet the production standards. After matching the order information, it can be verified bidirectionally with the order information. After the verification is passed, the system process in the above-mentioned Embodiment 1 is started for label printing.

[0064] The label printing unit can print the corresponding label according to the actual efficiency, customer information and / or order information. The content of the label includes customer information, order information, delivery information, production time, production line number, production base, solar cell parameters and printing log.

[0065] The customer information on the label can be used to identify the customer. The order information includes the total order information and the order information allocated to this production base. The delivery information is used to generate delivery-related information for the customer to check. The production time is used to ensure the production batch and product timeliness of the product. The production line number is used to identify the product production line information. The production base is used to mark the production base information of the product. The production line number and the production base can be used for internal verification and accountability within the enterprise. The solar cell parameters include, but are not limited to, solar cell efficiency, solar cell color, solar cell open-circuit voltage and other information. The printing log includes printing equipment information, printing time information, production equipment information and operator information, which can be used to specifically identify the specific machine that printed this label. When there is a problem with label printing, it is convenient to quickly find and repair the corresponding machine. The content carried by the above label can be used for tracing production information, solar cell parameters and other information.

[0066] The terminal module also includes a defect detection feedback system. When the cell parameters transmitted back by the terminal module to the main interface module do not match the customer demand parameters entered in the main interface module, the label printing unit will print a warning label. The warning label will mark the relevant parameters of the cell, including but not limited to cell efficiency, cell color, cell open-circuit voltage and other relevant information, and display the specific machine code to locate the problematic machine position, facilitating the staff to quickly find the production line machine for maintenance.

[0067] At the same time, all relevant information will be fed back to the main interface module through the sub-control module and / or the master control module for the administrator's analysis and improvement, facilitating the timely discovery of the defect causes of the cells, and timely improvement or production suspension to avoid greater losses.

[0068] The cell parameters include cell efficiency, cell color and cell open-circuit voltage.

[0069] The main interface module can transmit customer information and / or order information to the terminal module;

[0070] The terminal module also includes a defect detection feedback system, a sorter, a PLC and an industrial computer.

[0071] See Figure 1 、 2 、Figure 3, the operating status of the main interface module, the master control module, multiple sub-control modules and multiple terminal modules connected in sequence by signals:

[0072] When the business personnel receive a customer order, they log in to this system by entering their personal account password from the personal input end and enter the order information and customer information into the main interface module. The main interface module records the order information and, according to the production line and production capacity of each production base through the label metadata configuration unit in the main interface, divides the order into multiple corresponding output information, and forms an information source to be passed by the label metadata configuration unit to the information distribution unit of the master control module. The information distribution unit specifically passes it to the sub-control systems of the corresponding production bases. Then, the printing instruction unit of the sub-control system parses the transmitted information to a certain extent, converting the abstract signal information into concrete label information, including but not limited to parsing out customer and order information and the corresponding label templates, label corresponding fields, distributing the specific label serial numbers of each production line, forming the printing plan of this production base, etc., and then sending them one by one to the corresponding terminal modules connected by signals. The sorter in the terminal module sorts and counts the cells meeting the conditions and starts the label printing unit to print the corresponding labels.

[0073] See Figure 1 、 3 、Figure 4, the operating status of the information flow from the terminal module to the main interface module:

[0074] A battery cell is produced on the production line. The sorter and / or defect detection feedback unit and / or battery cell parameter detection unit in the terminal module identify the specific parameters of the battery cell, including but not limited to relevant information such as battery cell efficiency, battery cell color, and battery cell open circuit voltage. The terminal module sequentially transmits the above information to the main interface module through the PLC of the terminal module, the industrial control computer, the second information feedback unit of the sub-control module, and the first information feedback unit of the main control module. After receiving the information, the main interface module analyzes the above parameters through the data analysis and statistics unit and / or the customer management unit. The data analysis and statistics unit will store, analyze, and wait for extraction of the information. The customer management unit compares and verifies the above data with the battery cell parameters required by the existing customers in this unit. If the verification passes, the battery cell is a qualified battery cell, and it only needs to wait for further instructions from the system; if the verification fails, the error information is reported and waiting for the administrator to handle it.

[0075] Thus, the information transmission channel of this system is two-way, allowing two-way information transmission, that is, it can be transmitted from the main interface module to the terminal module, or from the terminal module to the main interface module. The two-way information transmission facilitates the matching and verification of two-way information to a certain extent, increasing the accuracy of label printing.

[0076] It can be seen from the above technical solutions that the present invention has the following beneficial effects:

[0077] 1. For the label system itself: It can carry more information and content, facilitating information traceability and product defect analysis. The distributed system architecture facilitates the integration, analysis, and traceability of production information from each base.

[0078] 2. For production enterprises: It can greatly save labor costs; facilitate group configuration management, enabling coordinated production capacity among multiple bases; reduce network latency and respond quickly; be safe, without backdoors, and reduce the impact of external cooperation on production capacity.

[0079] 3. For customers: The situation where labels are repeated and cannot be stored in the warehouse is not likely to occur, improving customer management capabilities and increasing customer stickiness.
