Technical Field

[0001] The present invention relates to the technical field of photovoltaic cells, and particularly to a method and device for preventing material mixing in the production of battery wafers. Background Art

[0002] When different types of battery wafers are produced in the same workshop, there is a risk of mixing of the battery wafers. Since the production processes and parameters of different types of battery wafers are different, if material mixing occurs during the production of battery wafers, it will cause incalculable harm and losses to battery wafer production enterprises. Therefore, it is necessary to let different types of battery wafers be in their respective positions during the production process of battery wafers to avoid material mixing and ensure the stable operation of the workshop. However, the existing battery wafer production technology mainly relies on manual or trolley handling of the flower baskets for feeding, and mainly relies on manual identification of the flower baskets to achieve anti-material mixing of different types of battery wafers. The accuracy and efficiency of manual identification are relatively low, and it is difficult for the identification personnel to maintain high efficiency and high intensity of work for a long time.

[0014] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0015] At present, the existing battery cell production technology mainly relies on manual or trolley handling of the flower baskets for feeding, and mainly relies on manual identification of the flower baskets to achieve anti-mixing of different types of battery cells. The accuracy and efficiency of manual identification are relatively low, and it is difficult for the identification personnel to maintain high efficiency and high intensity of work for a long time.

[0016] Based on this, an anti-mixing method and device for battery cell production provided by an embodiment of the present invention can alleviate the above problems existing in the related art.

[0017] For the convenience of understanding this embodiment, first, a detailed introduction is given to an anti-mixing method for battery cell production disclosed in an embodiment of the present invention. Refer to Figure 1 the flow schematic diagram of an anti-mixing method for battery cell production shown in

[0018] Step S102, obtain the coding information of the target flower basket on the feeding platform corresponding to the target process.

[0019] Among them, the target flower basket contains multiple battery cells of the same type, and the above coding information can represent the type of battery cells loaded in the corresponding flower basket.

[0020] Step S104, perform a first verification on the coding information of the target flower basket based on the preset information of the target process.

[0021] Among them, the above preset information can represent the preset battery cell type of the corresponding process.

[0022] Step S106, if the first verification fails, stop the feeding of the target flower basket and give a mixing alarm.

[0023] An anti-mixing method for battery cell production provided by an embodiment of the present invention obtains the coding information of the target flower basket on the feeding platform corresponding to the target process, performs a first verification on the coding information of the target flower basket based on the preset information of the target process, and if the first verification fails, stops the feeding of the target flower basket and gives a mixing alarm. By adopting the above technology, by stopping the feeding and giving an alarm when the verification of the coding information fails, the situation of mixing in the battery cell production process can be avoided, thereby avoiding the harm and loss caused by mixing.

[0024] As a possible implementation manner, the above step S104 (that is, performing a first verification on the coding information of the target flower basket based on the preset information of the target process) may include: verifying whether the coding information of the target flower basket matches the preset information of the target process; if the coding information of the target flower basket matches the preset information of the target process, the first verification passes; if the coding information of the target flower basket does not match the preset information of the target process, the first verification fails.

[0025] Exemplarily, the above preset information may include preset cell type information characterizing the preset cell type of the corresponding process, and the above encoding information may include first encoding information on the type of cells loaded in the corresponding carrier; based on this, it can be verified whether the first encoding information of the target carrier matches the preset cell type information of the target process. If they match, the verification passes; if not, the verification fails.

[0026] As a possible implementation manner, the above preset information may further include preset work order information, preset production line information, preset equipment information, etc. for the corresponding process, which is not limited herein; based on this, the above method for preventing material mixing in cell production may further include:

[0027] Step 1, obtain the real-time production information of the feeding platform corresponding to the target process.

[0028] Among them, the above real-time production information may include real-time work order information, real-time production line information, real-time equipment information, etc., which is not limited herein.

[0029] Step 2, perform a second verification on the real-time production information of the feeding platform corresponding to the target process based on the preset information of the target process.

[0030] Step 3, if the second verification fails, stop the feeding of the target carrier and give a material mixing alarm.

[0031] As a possible implementation manner, the above step 2 (i.e., performing a second verification on the real-time production information of the feeding platform corresponding to the target process based on the preset information of the target process) may include: verifying whether the real-time production information of the feeding platform corresponding to the target process matches the preset information of the target process; if the real-time production information of the feeding platform corresponding to the target process matches the preset information of the target process, the second verification passes; if the real-time production information of the feeding platform corresponding to the target process does not match the preset information of the target process, the second verification fails.

[0032] Exemplarily, the step of verifying whether the real-time production information of the feeding platform corresponding to the target process matches the preset information of the target process may include at least one of the following operation modes:

[0033] Operation mode 1, verify whether the real-time work order information of the feeding platform corresponding to the target process matches the preset work order information of the target process.

[0034] Operation mode 2, verify whether the real-time production line information of the feeding platform corresponding to the target process matches the preset production line information of the target process.

[0035] Operation mode 3, verify whether the real-time equipment information of the feeding platform corresponding to the target process matches the preset equipment information of the target process.

[0036] If the above real-time production information includes the preset work order information of the corresponding process, the above operation mode 1 can be adopted; if the above real-time production information includes the preset production line information of the corresponding process, the above operation mode 2 can be adopted; if the above real-time production information includes the preset equipment information of the corresponding process, the above operation mode 3 can be adopted; if the above real-time production information includes two or all of the preset work order information, preset production line information and preset equipment information of the corresponding process, two or all of the above operation modes 1 to 3 can be adopted.

[0037] Correspondingly, there are two results for verifying whether the real-time production information of the feeding platform corresponding to the target process matches the preset information of the target process, namely verification passed and verification failed. Whether the verification passes or fails is determined by the selection method and combination method among the above operation modes 1 to 3; for example, only select the above operation mode 1 or 2 or 3. If the result of the selected operation mode 1 or 2 or 3 is a match, the verification passes; if the result of the selected operation mode 1 or 2 or 3 is a mismatch, the verification fails; for another example, select two of the above operation modes 1 to 3. If the results of the two selected operation modes are both matches, the verification passes; if there is a mismatch in the results of the two selected operation modes, the verification fails; for still another example, select the above operation modes 1 to 3. If the results of the above operation modes 1 to 3 are all matches, the verification passes; if there is a mismatch in the results of the above operation modes 1 to 3, the verification fails.

[0038] As a possible implementation manner, the above target flower basket may have an RFID electronic tag containing coding information; based on this, the above step S102 (that is, obtaining the coding information of the target flower basket on the feeding platform corresponding to the target process) may include: reading the RFID electronic tag on the target flower basket through an RFID reader to obtain the coding information of the target flower basket.

[0039] Exemplarily, an RFID reader can be installed at a specified position on the feeding platform corresponding to the specified process. When the RFID electronic tag on a certain flower basket enters the reading range of the RFID reader, the RFID electronic tag on the flower basket can be read through the RFID reader to obtain the coding information contained in the RFID electronic tag.

[0040] As a possible implementation manner, the above step 1 (that is, obtaining the real-time production information of the feeding platform corresponding to the target process) may include: obtaining the real-time production information of the feeding platform corresponding to the target process through a Manufacturing Operation Management (MOM) system.

[0041] Since the MOM system should have the function of tracing production data for production quality control and production process improvement, the real-time production information of the loading platform corresponding to the target process can be obtained through the MOM system relying on its production data tracing function; for example, the production process of solar cells includes multiple processes. After a basket loaded with solar cells passes through the production of each process, the MOM system will generate the production information of the corresponding process and record the production information of the corresponding process and each process before it. That is, after the basket passes through the production of one or more processes, the MOM system will generate and record the production information of all processes passed by the basket. For the current process, the MOM system will generate the production information of the current process and record the production information of the current process and each process before it.

[0042] As a possible implementation manner, the above anti-mixing method for solar cell production may further include: uploading the coding information of the target basket to the manufacturing operation management system, so as to execute the above step S104 (i.e., performing the first verification on the coding information of the target basket based on the preset information of the target process) and the above step 2 (i.e., performing the second verification on the real-time production information of the loading platform corresponding to the target process based on the preset information of the target process) through the manufacturing operation management system.

[0043] Since the MOM system can also pre-store the preset information of the corresponding process (such as solar cell type information, preset work order information, preset production line information, preset equipment information, etc.), after the MOM system obtains the coding information of a certain basket and relies on the production data tracing function to obtain the real-time production information of the corresponding process, it can match the coding information and the real-time production information with the preset information to verify the coding information and the real-time production information, so as to obtain the result of passing or failing the verification.

[0044] For the sake of easy understanding, the above anti-mixing method for solar cell production is described exemplarily as follows with a specific application as an example.

[0045] Each basket is pre-assigned a corresponding unique 13-bit RFID code, and an RFID chip containing the corresponding unique 13-bit RFID code is implanted at a specified position of each basket. Each RFID chip has a corresponding UID code in addition to the corresponding RFID code. See Figure 2 shown, the coding rule of the 13-bit RFID code is:

[0046] The 1st - 2nd bits: factory code, taking values from 10 in sequence to 99; for example, using 10 to represent a certain factory.

[0047] The 3rd - 4th bits: silicon wafer specification code, taking values from 10 in sequence to 99; for example, using 10 to represent the silicon wafer specification of 210, and using 11 to represent the silicon wafer specification of 218.

[0048] Bits 5 - 6: Process type code, ranging from 00 to 99 in sequence; for example, 00 represents the general process type, 01 represents the PERC (Passivated Emitter and Rear Cell) process type, and 02 represents the TOPCON (Tunnel Oxide Passivated Contact) process type.

[0049] Bits 7 - 8: Basket type code, ranging from 01 to 99 in sequence; for example, 01 represents the dry basket type, 02 represents the wet basket type (texturing), and 03 represents the wet basket type (alkali polishing).

[0050] Bits 9 - 13: Basket serial number, ranging from 00001 to 99999 in sequence.

[0051] Taking the anti - mixing method for the production of the above - mentioned solar cells realized by the cooperation of an automated device (including an RFID reader) and an MOM system as an example, see Figure 3 As shown, the process of the anti - mixing method for the production of the above - mentioned solar cells mainly includes:

[0052] Step 11, The AGV cart sends the basket to the docking station.

[0053] The automated device has an anti - mixing mode selection switch, and relevant personnel can select the corresponding mode from the three modes of off - anti - mixing, automated anti - mixing, and MOM anti - mixing through the anti - mixing mode selection switch.

[0054] Step 12, Anti - mixing mode selection.

[0055] If the off - anti - mixing option is selected, the process ends directly; if the automated anti - mixing option is selected, proceed from step 12 to step 13; if the MOM anti - mixing option is selected, proceed from step 12 to step 21.

[0056] Step 13, The RFID reader of the automated device reads the RFID chip of the basket to obtain the corresponding RFID code, and enter step 14.

[0057] Step 14, The automated device verifies the RFID code.

[0058] The automation equipment mainly verifies the 5th and 6th bits of the 13-bit RFID code. For example, the product category (i.e., process type) of the current automated production preset by the automation equipment is P type (i.e., PERC). If the automation equipment reads 01 in the 5th and 6th bits of the 13-bit RFID code through the RFID reader, the verification passes and the process ends. If the automation equipment reads not 01 in the 5th and 6th bits of the 13-bit RFID code through the RFID reader, the verification fails and the process goes to step 15.

[0059] Step 15: the automation equipment alarms and shuts down, and the process goes to step 16.

[0060] Step 16, manual processing (such as taking the flower basket off the docking station) and clearing the alarm, then the process ends.

[0061] Step 21, the RFID reader of the automation equipment reads the RFID chip of the flower basket to obtain the corresponding RFID code, and reports the obtained RFID code to the MOM system, and then proceeds to step 22.

[0062] Step 22, the MOM system verifies the RFID code and the associated information of the corresponding flower basket.

[0063] The MOM system mainly verifies the 5th and 6th bits of the 13-bit RFID code and the product category, work order, production line, equipment and other information currently generated and recorded by the MOM system through the traceability function. The pass conditions set for the verification of the MOM system may include at least one of the following: the product category represented by the 5th and 6th bits of the 13-bit RFID code is the same as the preset product category of the MOM system, the work order information currently recorded by the MOM system is the preset work order information of the MOM system, the production line information currently recorded by the MOM system is the same as the preset production line information of the MOM system, and the equipment information currently recorded by the MOM system is the same as the preset equipment information of the MOM system. In addition, the pass conditions set for the verification of the MOM system may also include other conditions related to the information currently recorded by the MOM system, which are not limited to this.

[0064] If any of the set pass conditions is not met, the verification fails and the process proceeds to step 15 ; if all of the set pass conditions are met, the verification passes and the process proceeds to step 23 .

[0065] Step 23, the MOM system releases the flower basket and ends the process.

[0066] After a basket on the docking station has passed the MOM system verification, the basket can be loaded and the MOM system can record in real time the production information of the corresponding process of the battery cells loaded in the basket on the docking station.

[0067] Using the above anti-mixing method for solar cell production, it is possible to perform verification by solely using the RFID code obtained by an automated device to read the RFID chip, or to perform verification by using the RFID code obtained by an automated device to read the RFID chip in combination with the associated information obtained through the traceability function of the MOM system. Thus, two highly efficient and feasible automated anti-mixing methods are provided. Compared with the method of manually identifying the flower baskets in the prior art to achieve anti-mixing of different types of solar cells, it can improve the efficiency and accuracy of anti-mixing in the solar cell production process and reduce the waste of resources in terms of manpower and materials, thereby avoiding a series of losses caused by material mixing in the workshop during the solar cell production process.
