Embodiments of the present application will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that in the examples of the present application, numerous technical details are set forth in order to provide a better understanding of the present application. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.

Fig. 1 is a flowchart of a method for matching a crystal ingot according to an embodiment of the present disclosure.

Referring to fig. 1, an information base is established, which stores: the method comprises the steps of obtaining a plurality of original crystal bar information, wherein each original crystal bar information at least corresponds to one first crystal bar, the first crystal bar is a non-standard crystal bar which has undergone a bar matching step and is not successfully matched so as to wait for the bar matching, and in some embodiments, the original crystal bar information can be the length, diameter size, parameters and model of the first crystal bar, wherein the model refers to that the first crystal bar is an N-type semiconductor or a P-type semiconductor, and the parameters comprise a doping source of the first crystal bar, such as boron or gallium and doping concentration of the P-type semiconductor. In some embodiments, the original ingot information in the information base may be automatically entered by the system, for example, a code carrier may be disposed on the first ingot, and the code carrier carries information of each first ingot, and then the code carrier is automatically scanned by using an RFID (Radio Frequency Identification) technology to identify information of each first ingot, and the information is entered into the information base as the original ingot information. The code carrier is utilized to carry information of the first crystal bar, and the RFID technology is adopted to automatically identify the code carrier, so that the process of information input is highly automated, and the efficiency of information input can be improved. In other embodiments, the original crystal bar information can be manually recorded one by one.

In some embodiments, an information feedback unit may be provided, configured to record storage time of original ingot information in an information base, and screen out original ingot information whose storage time in the information base reaches a preset ingot matching time. In some embodiments, the preset rod matching time can be set according to the process progress, for example, when the construction period progress is required to be fast, the preset rod matching time can be set to be short, so that the first crystal rod information can be screened out more, and the second crystal rod matched with the first crystal rod corresponding to the first crystal rod information is prepared in a subsequent oriented manner, which is beneficial to improving the rod matching efficiency of the whole crystal rod matching process, thereby accelerating the construction period progress; for another example, when the time of the construction period is relatively long, the preset bar matching time may also be set to be relatively long, so that the original crystal bar information in the information base is relatively large, and thus, when the third crystal bar information to be matched is subsequently matched with the original crystal bar information in the information base, the success rate of matching the third crystal bar may be increased.

And preparing a second crystal bar based on the first crystal bar information and preset matching information, wherein the second crystal bar information corresponding to the second crystal bar is matched with the first crystal bar information. In some embodiments, the preset matching information is a predetermined information combination standard for matching and bonding two crystal bars required by a standard bar, that is, if the third crystal bar information of the bar to be assembled and any original crystal bar information satisfy a preset combination of the preset matching information, a standard bar is obtained after the third crystal bar corresponding to the third crystal bar information and the first crystal bar corresponding to the original crystal bar information are bonded. It is understood that, in some embodiments, the preset matching information may include a plurality of different combination criteria, for example, the preset matching information may be a combination criterion set based on the length of the ingot, that is, the combination criterion is whether the length of the two ingots after bonding meets the length of the ingot; for another example, the preset matching information may also be a combination standard set based on a model of the ingot, where the model includes: an N-type semiconductor or a P-type semiconductor, namely, a combination standard can be that crystal bars of the same type are bonded to obtain a standard bar; for another example, the preset matching information may also be based on a combination standard set by the length of the ingot and the model of the ingot, that is, the combination standard is: the length of the two crystal bars after being bonded needs to meet the length of a standard bar, and the types of the crystal bars need to be the same; for another example, the preset matching information may be a combination standard based on the knife shape setting in the slicing step, because after two crystal bars are bonded into a standard bar, the standard bar needs to be sliced, in the slicing step, there are multiple knife shapes for slicing, and different knife shapes may correspond to different standard bars, so the combination standard is set as follows: and matching crystal bars corresponding to the same knife shape to obtain standard bars.

And preparing a second crystal bar, wherein second crystal bar information corresponding to the second crystal bar and the first crystal bar information meet preset matching information, namely, screening out original crystal bar information which is not successfully matched for a long time in an information base to serve as first crystal bar information, responding to the matching requirement of the first crystal bar information, and directionally preparing the second crystal bar matched with the first crystal bar, so that the matching success rate of the first crystal bar information is greatly improved, and the problem of excessive information retention in the information base can be solved.

In some embodiments, a method of preparing a second boule may comprise: and acquiring second crystal bar information matched with the first crystal bar information based on the first crystal bar information, wherein the first crystal bar information can be obtained by screening original crystal bar information reaching the preset bar matching time in an information base through an information feedback unit.

Specifically, the method for acquiring the second crystal bar information may be: the MES system stores preset matching information, the information feedback unit feeds the first crystal bar information obtained through screening back to the MES system, and the MES system analyzes the first crystal bar information and acquires second crystal bar information matched with the first crystal bar information based on the preset matching information.

And providing an initial crystal bar, and cutting the initial crystal bar to prepare a second crystal bar corresponding to the second crystal bar information. In some embodiments, an ingot truncation device may be provided to truncate the initial ingot to obtain a second ingot, and the ingot truncation device may be a truncator. It is noted that the diameter size, parameters and type of the starting ingot need to be matched to the first ingot. Specifically, in some embodiments, an MES system may be set to be in communication connection with the ingot truncation device, the MES system obtains the second ingot information and then feeds the second ingot information back to the ingot truncation device, and the ingot truncation device truncates the initial ingot based on the second ingot information to prepare the second ingot. In some embodiments, there may also be a temporary absence of an initial ingot available that matches the diameter size, parameters, and model of the first ingot during the time the first ingot corresponding to the first ingot information is waiting for ingot matching. Utilize MES to carry out automatic analysis and feed back information to crystal bar cutting device, crystal bar cutting device is based on the automatic preparation second crystal bar of second crystal bar information, has realized high automated process, has improved process efficiency greatly.

And providing a plurality of third crystal bars to be matched, wherein the third crystal bars at least comprise a second crystal bar. The third ingot is a non-standard ingot waiting for ingot matching, and in some embodiments, the third ingot includes a non-standard ingot generated during a process of preparing a standard ingot in addition to a second ingot prepared in response to an orientation requirement of the first ingot information, and the third ingot is a non-standard ingot which has not undergone an ingot matching process.

And identifying the third crystal bars, and acquiring the information of the third crystal bars corresponding to each third crystal bar. Specifically, in some embodiments, the third crystal bar may be placed on the transmission line to recognize the third crystal bar one by one and acquire the third crystal bar information, so that the third crystal bar information may be subsequently matched with the original crystal bar information in the information base one by one, thereby improving the orderliness of the bar matching process and the bar matching efficiency.

In some embodiments, the third wand may be identified using radio frequency identification technology. The radio frequency identification technology belongs to the wireless identification technology, carries out non-contact bidirectional data communication in a wireless radio frequency mode, and can carry out automatic identification. Specifically, a code carrier may be disposed on the surface of the third crystal bar, and the code carrier carries information of each third crystal bar, including information of length, model, and the like. Meanwhile, a reader is arranged and used for scanning the code carrier and extracting information in the code carrier, and when a third crystal bar on the conveying line passes through the reader, the reader reads the information through the code carrier on the surface of the third crystal bar, so that the third crystal bar is identified and information of the third crystal bar is acquired. By utilizing the radio frequency identification technology, the third crystal bar can be automatically identified without adopting a manual mode to carry out statistics on the crystal bar information one by one, and the improvement of the crystal bar matching efficiency is facilitated. It is understood that in other embodiments, the code carrier may be disposed on the surface of the third crystal bar only, and a scan code is manually performed on the code carrier to obtain the information of the third crystal bar.

And judging whether the third crystal bar information is matched with the original crystal bar information in the information base or not based on preset matching information, and if the third crystal bar information is matched with any original crystal bar information, bonding the third crystal bar corresponding to the third crystal bar information and the first crystal bar corresponding to the original crystal bar information to obtain the standard bar. The information base is set, information integration is carried out on original crystal bar information corresponding to the first crystal bar which is not successfully matched with the crystal bar, after the third crystal bar information is obtained, the original crystal bar information matched with the third crystal bar information can be directly searched from the information base with relatively complete information, manual statistics and comparison are omitted, and crystal bar matching efficiency is improved.

In some embodiments, the third ingot information may be determined to match the original ingot information in the information base by using either automatic matching or manual matching. Specifically, in some embodiments, the method of automatic matching may include: the automatic conveying line is arranged and used for transmitting the third crystal bar, the reader is arranged on the automatic conveying line and used for recognizing the third crystal bar one by one, and in addition, the matching unit can be further arranged on the automatic conveying line and used for matching the third crystal bar information and the original crystal bar information in the information base. Specifically, the process of automatic matching may be: and the third crystal bars are placed on the automatic conveying line, the third crystal bars on the automatic conveying line are transmitted to the reader one by one, the reader identifies the code carrier on the third crystal bars and extracts the information of the third crystal bars, and the matching unit matches the information of the third crystal bars with the information of the original crystal bars in the information base. It is understood that, in some embodiments, when the third crystal bar is transported and identified by using the automatic transport line, the fourth crystal bar may be further disposed on the automatic transport line at the same time as the third crystal bar, and transported and identified at the same time as the third crystal bar. The fourth crystal bar is a standard crystal bar obtained in the process of preparing the standard crystal bar, that is, the fourth crystal bar and the third crystal bar are simultaneously placed on an automatic conveying line, and then the fourth crystal bar and the third crystal bar are identified. Specifically, after the third crystal bar and the fourth crystal bar are identified, the third crystal bar information is screened out to perform the subsequent matching process, because the fourth crystal bar itself is a standard crystal bar and the bar matching process is not required. Place third crystal bar and fourth crystal bar jointly and discern on the automatic conveying line, so can need not to increase the process of one step of selecting separately standard crystal bar and nonstandard stick again, carrying out information identification's in-process to third crystal bar, select standard crystal bar simultaneously, can save the process to accelerate the technology progress.

In some embodiments, the method of manual matching may include: placing the third crystal bar on the manual transport line, and scanning a code carrier on the third crystal bar on the manual transport line by using a code scanner by a worker to recognize the information of the third crystal bar; and searching whether the original crystal bar information meeting the preset matching information exists in the information base by the staff based on the third crystal bar information and the preset matching information.

In some embodiments, based on two matching modes, namely automatic matching and manual matching, the information base can be divided into: the online library, wherein first original crystal bar information used for automatic matching is stored in the online library; and the offline library stores second original crystal bar information for manual matching. That is to say, the information bases are respectively established according to the two modes of automatic matching and manual matching, so that the management of the information in the information bases is facilitated.

Fig. 2 is a flowchart of another method for matching crystal bars according to an embodiment of the present disclosure, and referring to fig. 2, in some embodiments, the method for determining whether third crystal bar information matches original crystal bar information in an information base includes: and searching first original crystal bar information stored in the on-line library based on the third crystal bar information to acquire the original crystal bar information meeting preset matching information, and screening out a third crystal bar corresponding to the third crystal bar and a first crystal bar corresponding to the first original crystal bar information to an automatic blanking conveying line to bond the third crystal bar and the first crystal bar if the third crystal bar information is matched with the first original crystal bar information in the on-line library. The automatic blanking conveying line is used for carrying out a bonding process, specifically, in some embodiments, an on-line library position can be set for placing a first crystal bar corresponding to first original crystal bar information in the on-line library, a clamping component can be further arranged, the clamping component is in communication connection with the matching unit, when the matching unit judges that first original crystal bar information matched with third crystal bar information exists in the on-line library, a first feedback signal is sent to the clamping component, and the clamping component transmits the matched third crystal bar and the first crystal bar to the automatic blanking conveying line based on the first feedback signal. When an automatic matching mode is adopted, the third crystal bar information is firstly matched with the first original crystal bar information in the on-line library, so that if the on-line library has the first original crystal bar information matched with the third crystal bar information, the first crystal bar corresponding to the first original crystal bar information can be automatically screened out and automatically transported to the automatic blanking conveying line, and meanwhile, the third crystal bar is transported to the automatic blanking conveying line so as to bond the third crystal bar and the first crystal bar, so that the automation from the matching step to the bonding step is realized, and the process efficiency is improved.

In some embodiments, if the third crystal bar information does not match the first original crystal bar information in the on-line library, the second original crystal bar information stored in the off-line library is searched based on the third crystal bar information to obtain original crystal bar information satisfying preset matching information, and if the third crystal bar information matches the second original crystal bar information in the off-line library, the third crystal bar and the first crystal bar corresponding to the second original crystal bar information are bonded manually. That is to say, when the automatic matching mode is adopted, if the first original crystal bar information in the on-line library is not matched with the third crystal bar information, the third crystal bar information can be compared with the second original crystal bar information in the off-line library, so that the success rate of matching the third crystal bar can be improved. Specifically, in some embodiments, an HMI (Human Machine Interface) may be provided, the HMI being communicatively connected to the matching unit, the HMI being configured to send a second feedback signal to the HMI when the matching unit determines that there is second original ingot information matching third ingot information in the offline library, the HMI displaying information of the second original ingot on the Interface based on the second feedback signal, and when receiving the second original ingot information, the HMI moving the third ingot corresponding to the third ingot information out of the automatic transport line and searching for a first ingot corresponding to the second original ingot information based on the second original ingot information to bond with the third ingot.

In some embodiments, if the third crystal bar information is not matched with the first original crystal bar information in the on-line library and the second original crystal bar information in the off-line library, the third crystal bar information is recorded in the on-line library as the first original crystal bar information. In this way, even if the third ingot is not successfully assembled in the current ingot assembly process, the third ingot information is recorded into the on-line library as the first original ingot information, and therefore, the ingot assembly, that is, the appearance of the third ingot information matching the first original ingot information can be waited for. The third crystal bar information which is not successfully matched in the bar matching procedure is recorded into the on-line library, so that the matching times of each piece of the third crystal bar information which is not successfully matched can be increased, and the matching success rate of the third crystal bar is increased.

In some embodiments, further comprising: and based on the preset offline time, moving the first original crystal bar information stored in the online library and reaching the preset offline time out to the offline library. The preset offline time is the preset offline time, and in some embodiments, the preset offline time can be set to be longer, so that longer matching time is provided for the original crystal bar information to be matched, and the matching success rate is increased. When the storage time of the first original crystal bar information in the on-line library reaches the preset off-line time, it is indicated that the first original crystal bar information is not successfully matched within a long time, and the probability that the first original crystal bar information is successfully matched is considered to be small. Therefore, the first original crystal bar information is moved out of the on-line library and then is recorded into the off-line library for manual matching, on one hand, a memory space can be provided for the first original crystal bar information waiting to be recorded, the storage space of the on-line library is reasonably utilized, the automatic matching success rate can be improved, on the other hand, the first original crystal bar information is recorded into the off-line library and is used as the second original crystal bar information for manual matching, so that the second original crystal bar information still has the opportunity of bar matching, the storage space of the whole information library is reasonably planned, and the overall bar matching success rate of the original crystal bar information is improved. It can be understood that the preset offline time is greater than the preset rod matching time, that is, the first original ingot information which is not successfully matched needs to reach the preset rod matching time before reaching the preset offline time, so that the second ingot can be directionally prepared based on the first original ingot information which reaches the preset rod matching time, that is, the matching process of the first original ingot information is manually intervened, and thus the probability that the matching of the first ingot corresponding to the first original ingot information is successful is greatly improved. And if the first original crystal bar information is not successfully matched after the second crystal bar is prepared, moving the first original crystal bar information out of the on-line library and recording the first original crystal bar information into the off-line library for manual matching.

In some embodiments, further comprising: and comparing the third crystal bar information corresponding to the bonded third crystal bar and the first crystal bar information corresponding to the first crystal bar with preset matching information to verify whether the bonded third crystal bar and the bonded first crystal bar meet expectations or not. Specifically, in some embodiments, since the code carriers are disposed on the surfaces of the third and first crystal bars, the code carriers on the surfaces of the third and first crystal bars may be scanned to obtain third and first crystal bar information, and the third and first crystal bar information may be compared with the preset matching information. In some embodiments, any one of the acquired third crystal bar information or the acquired first crystal bar information may be input into the MES system, for example, the acquired third crystal bar information may be input into the MES system, the MES system automatically displays preset first crystal bar information matched with the third crystal bar information based on the preset matching information, and then compares the actually acquired first crystal bar information with the preset first crystal bar information displayed by the MES system, and if the actually acquired first crystal bar information matches with the preset first crystal bar information, it is determined that the bonded third crystal bar and the first crystal bar are in accordance with expectations. Whether the bonded third crystal bar and the bonded first crystal bar meet expectations or not is verified, so that the bonded third crystal bar and the bonded first crystal bar can be well guaranteed to meet the requirements of standard crystal bars, and the yield of the subsequent standard crystal bar slicing process is favorably improved.

In some embodiments, further comprising: and binding the information of the bonded third crystal bar and the information of the bonded first crystal bar, namely updating the combined information of the bonded third crystal bar and the bonded first crystal bar. Specifically, the first standard ingot is formed by the bonded third ingot and first ingot. After the matched third crystal bar and the first crystal bar are bonded to form the first standard crystal bar, the length, the model, the applicable knife shape and other information of the first standard crystal bar are updated, so that before the first standard crystal bar enters the slicing process, a proper knife shape can be selected for the first standard crystal bar based on the information of the first standard crystal bar, and the yield of sliced products is favorably improved. In some embodiments, a sorting module may be further disposed on the automatic transport line, and after the information of the first standard ingot is updated, the information of the first standard ingot may be fed back to the sorting module, and the sorting module sorts the first standard ingot based on the information of the first standard ingot, and selects a suitable knife shape for a slicing process of the first standard ingot.
