After the full feeder is transported to the furnace, it is also necessary to manually check the raw material information in the full feeder with the raw material demand information of the furnace, and add the raw materials to the furnace after the information is checked. When checking the information, since the materials in the feeder are mixed with multiple raw materials, it is difficult to identify the type of materials by the human eye.

[0028] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, each other embodiment obtained by those skilled in the art without making creative work belongs to the scope of protection of the present application.

[0029] It is worth noting that before the present application was proposed, monocrystalline silicon was a semiconductor material and was widely used in technical fields such as integrated circuits and solar cells. It has become an important cornerstone of the modern electronics industry with its unique conductivity and stability. In the manufacturing process of monocrystalline silicon, the feeder loaded with raw materials needs to be transported to the furnace in the loading area of ​​the monocrystalline silicon pulling workshop, and the raw material information label is manually attached to the feeder trolley board. The raw material information label adopts a disposable, pasteable, paper label. After the full feeder is transported to the furnace, in the feeding process, it is also necessary to manually check the raw material information in the full feeder with the raw material demand information of the furnace, for example: check the furnace number, raw material, addition times, barrel times, and material car number, and add the raw material to the furnace after the match is successful. After the furnace is filled and the feeder is removed from the furnace, the empty feeder enters the preparation process, and then the old raw material information label is manually torn off, and the empty feeder without a label is transported to the loading area for repeated loading. However, the raw material information labels on the feeders are currently paper labels, which are prone to falling off or incorrectly affixed during transportation. The raw material information labels do not match the raw material requirements of the furnace or cannot effectively identify problems with the raw materials in the feeder, requiring rework and reloading, resulting in long furnace feeding time and low furnace feeding efficiency.

[0030] Based on this, an embodiment of the present application provides a re-feeding control system to improve the furnace feeding efficiency during the furnace feeding process and shorten the feeding time.

[0031] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of a re-feeding control system provided in the embodiment of the present application. Figure 1 As shown, the re-feeding control system 10 provided in the embodiment of the present application includes a furnace table 100, a manufacturing execution unit 200, an automatic feeding unit 300, a feeder 400, a display control unit 500, and a display device 600, and the display device 600 is fixedly installed on the feeder 400. Figure 1 In the figure, the feeder 400 and the display device 600 are connected by a dotted line to indicate a fixed installation relationship between the display device 600 and the feeder 400.

[0032] The automatic feeding unit 300 is used to generate a feeding task based on the raw material demand information released by the furnace 100, obtain the target raw material according to the raw material demand information in the feeding task, and generate a movement control instruction for the feeder;

[0033] The feeder 400 is used to move to a designated position in response to a movement control instruction and receive and load a target raw material;

[0034] The automatic feeding unit 300 is further used to read the device identification of the feeder 400 located at the designated position, bind the device identification with the feeding task, and send the feeding task bound with the device identification to the display control unit 500;

[0035] A display control unit 500 is used to extract important information in the loading task and send the important information to a display device 600 corresponding to the feeder 400;

[0036] The feeder 400 is also used to move to the location of the furnace stage 100 and to deliver the target raw materials loaded in the feeder 400 into the furnace stage 100 when the important information matches the raw material demand information.

[0037] The re-feeding control system provided in the embodiment of the present application can obtain the electronic tag (the electronic tag is the information used to characterize the raw material) through the display device arranged on the feeder, and then match the electronic tag with the raw material demand information, and deliver the material to the furnace according to the matching result, thereby avoiding the raw material information label on the feeder from falling off or the label being mis-attached, shortening the time for feeding the furnace, and improving the efficiency of feeding the furnace, solving the problems of long time and low efficiency of feeding the furnace during the feeding process.

[0038] To facilitate understanding of this embodiment, each of the above-mentioned exemplary units provided in the embodiment of the present application is described below.

[0039] Refer to the following Figure 2 Let's introduce the raw material re-feeding process of the re-feeding control system.

[0040] Figure 2 A schematic diagram showing the raw material re-feeding process of the re-feeding control system provided in the embodiment of the present application is shown as follows: Figure 2 As shown, the furnace station releases the raw material demand information according to the current production process. The raw material demand information includes the number of additions, the number of barrels for each addition, the raw material number, and the initial raw material weight corresponding to each raw material number. The raw material numbers for different additions and different barrels can be different, that is, the raw materials loaded in the feeders between different additions and different barrels are different.

[0041] Here, the furnace may refer to the furnace equipment set up in a single crystal silicon pulling workshop for single crystal silicon pulling. The main purpose of single crystal silicon pulling is to convert polycrystalline silicon raw materials into single crystal silicon rods for further processing into silicon wafers, which are ultimately used to manufacture semiconductor devices and integrated circuits.

[0042] The current production process may refer to a specified process in the process of single crystal silicon pulling. As an example, the current production process may be a seeding process of single crystal silicon pulling. Different processes require different raw materials. Therefore, the raw material demand information released by the furnace under different processes is also different.

[0043] The furnace sends the published raw material demand information to the Manufacturing Execution System (MES). After receiving the raw material demand information, the Manufacturing Execution System generates the re-feeding task corresponding to this round of feeding based on the raw material demand information.

[0044] Among them, the total number of re-feeding tasks generated by the manufacturing execution unit corresponds to the number of times in the raw material demand information, each re-feeding task corresponds to one time, and each time corresponds to one round of feeding process. For example: the number of times in the raw material demand information is 3, indicating that the manufacturing execution unit generates a total of three re-feeding tasks under the current production process and executes three rounds of feeding processes. If the number of times in the raw material demand information released by the furnace is three during this round of feeding, it means that two rounds of feeding have been carried out before this round of feeding process, and this round of feeding process is the third round. In addition, the raw material demand information also includes barrel times, which indicates how many barrels of raw materials need to be added during this round of feeding. The re-feeding tasks corresponding to this round of feeding process also include barrel times, which indicates the number of barrels required for feeding under the third round of feeding process. The manufacturing execution unit sends the re-feeding tasks corresponding to this round of feeding to the automatic feeding unit, so that the automatic feeding unit generates loading tasks according to the re-feeding tasks.

[0045] The automatic feeding unit receives the re-feeding task and creates a loading task based on the re-feeding task. Each feeding includes multiple barrels, and the barrels in different feedings can be different. One barrel corresponds to one use of the feeder. For example, if the barrel in the re-feeding task is 5, then 5 loading tasks are created and executed.

[0046] Take the execution of a loading task as an example. At this time, the material can be automatically batched according to the raw material demand information in the loading task to obtain the target raw material from the raw material warehouse. Then, the target raw material is automatically taken out of the warehouse and transferred to the loading position. At the same time, the automatic feeding unit generates a movement control instruction for the feeder to control the feeder to move to the specified position.

[0047] There are multiple feeders, and the automatic feeding unit selects a feeder in an empty state from the multiple feeders as a target feeder to control the selected target feeder to move to a specified position. The empty state may refer to a feeder that is not loaded with raw materials.

[0048] The mobile control instruction includes the coordinates of the designated position. The feeder includes an AGV trolley. The target feeder can move according to the mobile control instruction and locate the current position in real time. When it moves to the designated position, it receives the target raw material to be loaded.

[0049] At the same time, the automatic feeding unit determines whether the target feeder has reached the specified position. If it is determined that the target feeder has reached the specified position, the device identification of the target feeder (the target feeder located at the specified position) is read, the device identification is bound to the loading task, and the loading task bound to the device identification is pushed to the display control unit. If it is determined that the target feeder has not moved to the specified position, the unloaded target feeder continues to be controlled to move to the specified position until it reaches the specified position. Among them, the loading task bound to the device identification includes: furnace number, raw material number, addition times, barrel times, and device identification. The furnace number can refer to the number of the furnace, the raw material number can refer to the unique identification of the raw material, and the raw material numbers of different raw materials are different. The addition times can refer to the batch of raw materials added, and the barrel times can refer to the number of barrels of raw materials added under the same addition times. The device identification can refer to the code of the target feeder, and the code of the feeder is also called the feeder car code.

[0050] At the same time, after the automatic feeding unit determines that the target feeder has reached the specified position and reads the device identification of the target feeder, it determines whether the target raw material matches the raw material demand information. For example, if there are multiple target raw materials, the raw material number of each target raw material is matched with the raw material number in the raw material demand information. If the raw material number of each target raw material can find the raw material number in the raw material demand information that matches it, it is determined that the target raw material matches the raw material demand information. Conversely, if the raw material number of any target raw material cannot find the raw material number in the raw material demand information that matches it, it is determined that the target raw material does not match the raw material demand information.

[0051] In one case, if the target raw material matches the raw material demand information, the target feeder is charged, i.e., automatically charged. The automatic charging unit determines whether the charging is completed, i.e., whether the feeder is full of raw materials. If the charging is not completed, the automatic charging continues; if the charging is completed, the empty target feeder becomes a fully loaded target feeder, at which point the charging task is completed, and the fully loaded target feeder is controlled to move toward the furnace.

[0052] In another case, if the target raw material does not match the raw material demand information, it means that the target raw material at this time is not the raw material required by the furnace, then an alarm is issued to the staff, and a new target raw material is reselected to load the reselected new target raw material.

[0053] In one example, after determining that the target raw material matches the raw material demand information, it is also necessary to inspect the target feeder to determine whether the feeder type of the target feeder matches the preset feeder type indicated in the raw material demand information. Only after the target raw material matches the raw material demand information and the target feeder passes the inspection can the target feeder be charged. Here, the feeder type includes N type and P type, the raw material demand information includes the material type, and the material type includes N type and P type. If the feeder type of the target feeder is consistent with the material type, for example: both are N type or both are P type, then it is determined that the target feeder has passed the inspection. If the feeder type of the target feeder is inconsistent with the material type, then it is determined that the target feeder has not passed the inspection. When the target feeder fails the inspection, loading cannot be performed.

[0054] The display control unit determines whether a loading task is received. If a loading task is received, important information in the loading task is extracted and sent to the display device corresponding to the target feeder, and the display device displays the important information. In this way, the display device of the fully loaded target feeder displays the important information of the loading task corresponding to the target feeder and keeps the information displayed. Among them, the important information includes the furnace number, raw material number, number of additions, number of barrels, and device identification. The display device uses an electronic ink screen, and the display content in the display device can be maintained when the power is off. Each display device has a unique identification. The display control unit can simultaneously push and display important information to multiple display devices with specified numbers, and the display device and the display control unit communicate wirelessly through a base station. If it is determined that the loading task has not been received, the important information of the loading task cannot be extracted. At this time, the important information will not be displayed on the display device, and the information display will be maintained, that is, the important information will not be displayed.

[0055] In one example, the furnace station also obtains important information displayed on the display device of the target feeder moved to the furnace station, and compares the raw material demand information with the important information, and determines whether the important information matches the raw material demand information based on the material number. For example, the raw material number in the important information is called the first raw material number, and the number in the raw material demand information is called the second raw material number. For each first raw material number in the important information, determine whether there is a second raw material number corresponding to the first raw material number in the raw material demand information. If each first raw material number has a corresponding second raw material number, it is determined that the important information matches the raw material demand information. If there is a first raw material number that does not have a corresponding second raw material number, it is determined that the important information does not match the raw material demand information. If the important information matches the raw material demand information, the target raw material in the target feeder is fed into the furnace station. If the important information does not match the raw material demand information, manual processing is performed.

[0056] In addition, the raw material weight corresponding to each first raw material number in the important information can be compared with the initial raw material weight corresponding to the second raw material number in the raw material demand information. When the raw material weight corresponding to the first raw material number matches the initial raw material weight in the raw material demand information, it is determined that the important information matches the raw material demand information.

[0057] In another example, the important information displayed on the display device of the target feeder may be matched with the raw material demand information manually.

[0058] After the important information matches the raw material demand information, the target raw material in the target feeder can be automatically fed into the furnace, or the target raw material in the target feeder can be manually fed into the furnace. Then, after the target raw material is fed into the furnace, the empty target feeder is taken out.

[0059] After taking out the empty target feeder, the furnace will issue a recycling request for the target feeder to recycle the feeder for raw material transportation. The furnace sends the recycling request to the manufacturing execution unit, which receives the recycling request, generates a feeder recycling instruction based on the recycling request issued for the target feeder, and sends the feeder recycling instruction to the automatic feeding unit. Among them, the manufacturing execution unit is mainly used to monitor the feeding process and the feeder recycling process.

[0060] The automatic feeding unit receives the feeder recovery instruction and generates a feeder recovery task based on the feeder recovery instruction. After the automatic feeding unit generates the feeder recovery task, it controls the unloaded target feeder to move to the specified position to execute the feeder recovery task. Then, the automatic feeding unit repeats the previous processing, that is, determining whether the target feeder has moved to the specified position. If it is determined to have moved to the specified position, the step of reading the device identification of the target feeder located at the specified position is executed to form a cyclic execution process.

[0064] Step S102, the feeder moves to a designated position and loads the target raw material in response to the movement control instruction;

[0065] Step S103, the automatic feeding unit determines whether the feeder has moved to the designated position. If it is determined to have moved to the designated position, the device identification of the feeder at the designated position is read, the device identification is bound to the feeding task, and the feeding task bound to the device identification is sent to the display control unit;

[0066] Step S104, the display control unit extracts important information in the loading task and sends the important information to the display device corresponding to the feeder;
