Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic glass production equipment and process, in particular to a one-kiln multi-line original sheet production line and deep processing line arrangement process and control method. BACKGROUND

[0002] In a one-kiln multi-line large photovoltaic glass factory, as the tonnage of the original glass sheet increases, the original sheet branch line and the deep processing branch line increase more and more. Although the traditional "full roller direct connection" has high transmission efficiency and reduces the link of transferring the original sheet to the deep processing line by forklift after the original sheet is unloaded, the roller arrangement will intersect and occupy the middle passage, forming a fragmented dead zone, which causes trouble for equipment maintenance and material transportation. Moreover, the production capacity of all branch lines needs to be strictly matched with the production capacity of the deep processing line. Once a deep processing process fails or the beat fluctuates, it will have a chain effect on the original sheet end, lacking buffering and scheduling capacity. For example, the original sheet is produced for 24 hours, while the deep processing is produced for about 22 hours per day, which will cause a mismatch in production capacity.

[0003] In addition, in the deep processing production of photovoltaic glass, the quality of the original sheet for producing cover plates is generally higher than that of the back plate. When producing on the cover plate deep processing line, if part of the products in the original sheet production line do not meet the quality requirements of the cover plate deep processing line, but can meet the quality requirements of the back plate deep processing line, the existing production generally disposes the waste products as waste, resulting in a huge waste of resources.

[0004] Furthermore, when the thickness of the plate material in the width direction of the plate is different after calendering, if it is directly connected to the coating / tempering, quality problems such as "coating leakage" are easy to occur. When the production capacity of a single line is increased to 400-500 t in the future, the contradiction between the production capacity of the original sheet side and the deep processing side will be more prominent, and it is urgent to introduce a mixed connection of direct connection + AGV and a flexible absorption means of buffer storage.

[0005] In summary, the existing photovoltaic glass production line connection method has the following technical problems:

[0006] 1. Although the full roller direct connection method has high transmission efficiency, it completely blocks the middle passage and lacks flexibility;

[0007] 2. The full roller direct connection method cannot realize the selection and transfer of the original glass sheet;

[0008] 3. The full roller direct connection method cannot completely match the production capacity of all original sheet branch lines with the production capacity of the deep processing line, and cannot cope with production fluctuations;

[0009] 4. When the deep processing line equipment is out of production, there is a lack of effective buffering and scheduling mechanism;

[0010] 5. The single connection method cannot fully utilize the production space, affecting the overall layout efficiency;

[0011] 6、Original sheet exists the problem of thickness difference in the width direction of the plate, and the subsequent film plating process is prone to plating leakage.

[0012] 7、Future super large tonnage production line (400-500t / d) production capacity and deep processing equipment processing capacity do not match, need flexible scheduling. SUMMARY

[0022] To achieve the above or other objectives, this invention also discloses a control method for a multi-line raw material production line and a deep processing line in a single kiln. The method employs the aforementioned multi-line raw material production line and deep processing line layout process, where multiple raw material production lines and multiple deep processing lines are connected via roller conveyor direct connection modules and AGV transfer modules. The intelligent scheduling module dynamically allocates, controls congestion, and transfers excess capacity between the roller conveyor direct connection modules and the AGV transfer modules according to daily production requirements, coordinating the operation of the roller conveyor direct connection modules and the AGV transfer modules to achieve production scheduling. During normal production, the roller conveyor... All or most of the raw wafers on the direct connection module go directly into the corresponding deep processing line for production. A small portion of the raw wafers are transferred to other deep processing lines or stored via the AGV transfer module. When the capacity of the raw wafer production line on the roller conveyor direct connection module is greater than the capacity of the deep processing line, the excess raw wafers on the raw wafer production line are stored via the AGV transfer module. When the capacity of the raw wafer production line on the roller conveyor direct connection module is less than the capacity of the deep processing line, the insufficient raw wafers on the deep processing line are transferred from the AGV transfer module or from other raw wafer production lines.

[0023] As described above, the layout process and control method of a multi-line raw sheet production line and deep processing line in a single kiln involved in this invention have the following beneficial effects:

[0024] 1. This invention combines a roller conveyor direct connection module, an AGV transfer module, and an intelligent scheduling module. This combination maintains the efficiency of linear transmission while introducing flexible cross-line scheduling capabilities, enabling flexible connections between multiple large-tonnage raw material production lines and multiple deep-processing lines. The optimized combination of the roller conveyor direct connection module and the AGV transfer module frees up transfer channels and buffer areas, facilitating logistics and maintenance.

[0025] 2. This invention reduces the frequent loading and unloading of sheets by setting up a direct roller conveyor module, thereby reducing the powder spraying process, lowering the breakage rate, and enabling sheet selection and transportation, thus improving the yield. The intelligent scheduling module can dynamically allocate raw sheets to suit production volume and specifications, and can also temporarily store excess capacity, thereby improving automation rate and increasing production line resilience.

[0026] 3. This invention is particularly suitable for connecting the raw glass and deep processing steps in ultra-white rolled photovoltaic glass production lines, and is applicable to a production layout of 1200t~3000t / d with multiple lines in one kiln.

[0027] 4. This invention employs a hybrid connection method combining direct roller conveyor connection and AGV transfer, flexibly connecting multiple deep processing lines: the outer raw material production line and the deep processing line are directly connected via roller conveyors, configured with deep processing equipment of corresponding output, while AGVs can assist in loading and unloading; the middle raw material production line uses a robotic unloading device to unload sheets, which are then transferred by AGVs to the deep processing loading area. The roller conveyor layout design extends upwards and downwards, providing more space for the middle AGV transfer area and facilitating the setting up of buffer storage. This system dynamically allocates resources between the roller conveyor direct connection module and the AGV transfer module through intelligent scheduling, achieving balanced production capacity and handling of anomalies, solving problems such as poor flexibility of traditional direct connections, plating defects due to thickness differences, and chain stoppages caused by fluctuations in deep processing cycle time. The roller conveyor direct connection module reduces the breakage rate and the number of powder spraying processes, while the AGV transfer module dynamically adjusts defective cover sheet raw materials into back sheet raw materials, avoiding plating defects caused by thickness differences and improving the yield. It is particularly suitable for the flexible scheduling needs of future large-tonnage raw material production lines with a capacity of 300t / d or more, and can be expanded to large-tonnage production lines with a single line capacity of 400-500t / d.

[0036] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0037] It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings of this specification are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of the invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention's implementation.

[0038] like Figures 1-6 As shown, this invention provides a process for arranging a multi-line raw material production line and a deep processing line in a single kiln, including a roller conveyor direct connection module, an AGV transfer module, and an intelligent scheduling module; multiple raw material production lines and multiple deep processing lines are connected through the roller conveyor direct connection module and the AGV transfer module; the intelligent scheduling module dynamically allocates, controls congestion, and transfers excess capacity between the roller conveyor direct connection module and the AGV transfer module, coordinating the work of the roller conveyor direct connection module and the AGV transfer module to achieve production scheduling.

[0039] Preferred, such as Figure 1 As shown, the roller conveyor direct connection module includes a direct roller conveyor 201, a steering roller conveyor 203, an intersecting roller conveyor 202, and a robotic loading / unloading device 205. The raw glass production line is connected to the deep processing line through the direct roller conveyor 201, the steering roller conveyor 203, and the intersecting roller conveyor 202. The steering roller conveyor 203 is located in the direct roller conveyor 201 and is used for steering the transport of raw glass. The intersecting roller conveyor 202 is located in the direct roller conveyor 201 and cooperates with the robotic loading / unloading device 205 to unload or load glass from the direct roller conveyor 201. The robotic loading / unloading device 205 is located outside the intersecting roller conveyor 202 and is communicatively connected to the AGV transfer module. The robotic loading / unloading device 205 can both load and unload glass, enabling a flexible connection between the roller conveyor direct connection module and the AGV transfer module, and in particular, enabling the selection and transportation of raw glass sheets.

[0040] Preferred, such as Figure 1As shown, the direct-connection roller conveyor module also includes an opening and closing roller conveyor 204, which is disposed within the direct-connection roller conveyor 201. When closed, the opening and closing roller conveyor 204 is used to transport the original film; when open, it facilitates material flow between the two sides. The number and location of the opening and closing roller conveyors 204 can be selected according to actual conditions, ensuring convenient material flow between the two sides and easy inspection and maintenance.

[0041] Furthermore, such as Figure 1 As shown, each roller conveyor direct connection module has two direct connection roller conveyors 201, so the included turning roller conveyor 203 and cross roller conveyor 202 are also adapted to the double direct connection roller conveyors 201. The whole can achieve a cycle time of 5 seconds / set, which is compatible with the batching cycle time requirements of 0-650t / d production. The roller conveyor direct connection module can reduce the powder spraying process and reduce the breakage of the first unloaded film during the loading process.

[0042] Preferred, such as Figures 1-6 As shown, at least two roller conveyor direct connection modules are provided. These two modules are respectively installed on the two outer raw material production lines, and the direct connection roller conveyor 201 of the two modules extends outwards via the steering roller conveyor 203. The area between the two roller conveyor direct connection modules is used to install the AGV transfer module and the intelligent scheduling module. Furthermore, the two roller conveyor direct connection modules are respectively installed on the two outer raw material production lines, forming upward and downward expansions, thus freeing up the central area for the AGV transfer module and the intelligent scheduling module.

[0043] Preferred, such as Figure 1 As shown, the AGV transfer module includes a robotic unloading device 301, a robotic loading device 306, an AGV trolley 302, a buffer stack 303, a buffer material storage 304, and a transfer path 305. The robotic unloading device 301 is located in the unloading area of ​​the original film production line, the robotic loading device 306 is located in the loading area of ​​the deep processing line, the buffer stack 303 and the buffer material storage 304 are located in the area between the unloading area of ​​the original film production line and the loading area of ​​the deep processing line, and the transfer path 305 covers the unloading area of ​​the original film production line, the loading area of ​​the deep processing line, and the area between the two. The AGV trolley 302 can move along the transfer path 305 to transport the original film.

[0044] Preferred, such as Figure 1As shown, the buffer storage 303 is used to store racks containing original wafers, and the buffer material storage 304 is used to store empty racks. The intelligent scheduling module controls the AGV trolley 302 to extract empty racks from the buffer material storage 304 and transport them to the wafer unloading area of ​​the original wafer production line via the transfer path 305 for the robotic unloading device 301 to unload wafers. After unloading, the AGV trolley 302 transports the rack containing original wafers to the buffer storage 303. The intelligent scheduling module controls the AGV trolley 302 to extract racks containing original wafers from the buffer storage 303 and transport them to the wafer loading area of ​​the deep processing line via the transfer path 305 for the robotic unloading device 306 to load wafers. After loading, the AGV trolley 302 transports the empty racks to the buffer material storage 304.

[0045] In this embodiment, since the robotic arm loading and unloading device 205 is also communicatively connected to the AGV transfer module, when the capacity of the raw material production line in the roller conveyor direct connection module is higher than that of the corresponding deep processing line (such as...), Figure 1 When the production capacity of L1 and Ln in the AGV transfer module is lower than that of the corresponding deep processing line, the AGV transfer module controls the AGV trolley 302 to transport the empty material rack to the robotic loading and unloading device 205. The robotic loading and unloading device 205 places the original sheets from the roller conveyor direct connection module onto the empty material rack, and then transports them to the buffer stack 303 for storage via the AGV trolley 302. When the production capacity of the original sheet production line in the roller conveyor direct connection module is lower than that of the corresponding deep processing line, the AGV transfer module controls the AGV trolley 302 to transport the material rack containing the original sheets in the buffer stack 303 to the robotic loading and unloading device 205. The robotic loading and unloading device 205 places the original sheets from the material rack onto the roller conveyor direct connection module to complete the replacement.

[0046] Preferably, in this application, the intelligent scheduling module includes an AGV scheduling system, an MES system, and a raw film inspection system. The AGV scheduling system is communicatively connected to the AGV transfer module and the roller conveyor direct connection module. The MES system is used to track the transport path of the raw film. The raw film inspection system is used to inspect the quality of the raw film and feed the inspection results back to the AGV scheduling system.

[0047] Preferably, in this application, the multiple deep processing lines include a cover plate line and a composite line. The cover plate line is used to produce cover plates, and the composite line is used to produce cover plates or back plates. The quality of the raw sheet used to produce cover plates is higher than that used to produce back plates. The raw sheet inspection system detects the quality of the raw sheet and distinguishes raw sheets of different qualities through an AGV scheduling system.

[0048] When the raw film inspection system detects that the raw film quality meets the production quality requirements for the backplate but not for the cover plate, the robotic loading and unloading device 205 in the roller conveyor direct connection module unloads raw films of different qualities. The robotic unloading device 301 in the raw film production line unloading area places raw films of different qualities on different racks. Finally, raw films that meet the production quality requirements for the cover plate enter the cover plate line to produce the cover plate, while raw films that do not meet the production quality requirements for the cover plate but meet the production quality requirements for the backplate enter the integrated line to produce the backplate. Raw films that do not meet the production quality requirements for the backplate are scrapped to reduce the scrap rate.

[0049] In addition, the original film inspection system can also detect specific thickness differences in the original film, distinguishing between original films with thickness differences within a certain range and those outside that range. Original films with different thickness differences are then transported to the subsequent coating process, where they are coated using specific parameters to avoid incomplete coating due to thickness differences.

[0050] This application dynamically allocates raw films to various deep processing lines based on the output of the raw film production line, the product specifications, quality requirements, and production cycle of the deep processing production line, and temporarily stores excess capacity of the raw film production line in the AGV transfer module.

[0051] To achieve the above or other objectives, this invention also discloses a control method for a multi-line raw wafer production line and a deep processing line in a single kiln. The method employs the aforementioned multi-line raw wafer production line and deep processing line layout process, where multiple raw wafer production lines and multiple deep processing lines are connected via roller conveyor direct connection modules and AGV transfer modules. An intelligent scheduling module dynamically allocates, controls congestion, and transfers excess capacity between the roller conveyor direct connection modules and AGV transfer modules based on daily production requirements, coordinating the work of the roller conveyor direct connection modules and AGV transfer modules to achieve production scheduling. During normal production, all or most of the raw wafers on the roller conveyor direct connection modules directly enter the corresponding deep processing line (e.g., ...). Figure 1 Production takes place on L1 and Ln (in the original text), with a small portion of the raw materials being transferred to other deep processing lines (such as L1 and Ln) via AGV transfer modules. Figure 1 The excess raw sheets on the raw sheet production line (L2-L4) or through the AGV transfer module are stored. When the capacity of the raw sheet production line on the roller conveyor direct connection module is greater than the capacity of the deep processing line, the excess raw sheets on the raw sheet production line are stored through the AGV transfer module. When the capacity of the raw sheet production line on the roller conveyor direct connection module is less than the capacity of the deep processing line, the insufficient raw sheets on the deep processing line are transferred from the AGV transfer module or from other raw sheet production lines.

[0052] To describe in detail the control methods for a single-kiln, multi-line raw wafer production line and a deep-processing line, the following embodiments are disclosed:

[0053] First embodiment:

[0054] In this embodiment, a five-line specification with one kiln is adopted, with a daily output of 1200t / d of raw slices; the raw slice production lines are the first raw slice production line 101, the second raw slice production line 102, the third raw slice production line 103, the fourth raw slice production line 104, and the fifth raw slice production line.

[0055] like Figure 1 , Figure 3 As shown, the first raw wafer production line 101 and the fifth raw wafer production line are connected to the deep processing line via roller conveyor direct connection modules. The second raw wafer production line 102, the third raw wafer production line 103, and the fourth raw wafer production line 104 are connected to the deep processing line via AGV transfer modules. Due to the high speed of the roller conveyor direct connection modules, the daily output of 1200 t / d is distributed across the five raw wafer production lines as follows: 300 t / d for the first raw wafer production line 101, 200 t / d for the second raw wafer production line 102, 200 t / d for the third raw wafer production line 103, 200 t / d for the fourth raw wafer production line 104, and 300 t / d for the fifth raw wafer production line.

[0056] Among them, the two deep processing lines corresponding to the first raw wafer production line 101 and the fifth raw wafer production line are 60m cover plate lines, and the capacity of the deep processing lines is lower than that of the raw wafer production lines. The three deep processing lines corresponding to the second raw wafer production line 102, the third raw wafer production line 103, and the fourth raw wafer production line 104 are 60m integrated lines, and the capacity of the deep processing lines is higher than that of the raw wafer production lines.

[0057] When in operation, the "direct connection priority + small amount of AGV diversion" mode is activated: the roller conveyor direct connection mode is fully open, and the AGV control system will unload about 10% of the raw material quantity (including raw materials that do not meet the cover plate quality but meet the back plate quality) from the first raw material production line 101 and the fifth raw material production line through the robotic loading and unloading device 205, and then divert and store them in the buffer stack 303 by the AGV trolley 302.

[0058] When either the first raw wafer production line 101 or the fifth raw wafer production line stops production, the AGV transfer module handles 100% of the raw wafer scheduling on those two lines, with excess raw wafers stored in the buffer stack 303. When either the first or fifth raw wafer production line stops production, the AGV transfer module retrieves raw wafers from the buffer stack 303 and places them onto the first or fifth raw wafer production lines via the AGV trolley 302 and the robotic loading / unloading device 205, completing the delivery of raw wafers to the subsequent deep processing lines. Similarly, when the second, third, and fourth raw wafer production lines 102 and their corresponding deep processing lines malfunction, the AGV transfer module can also perform reasonable scheduling to ensure stable wafer supply and flexible scheduling in this embodiment.

[0059] Raw wafers from the second raw wafer production line 102, the third raw wafer production line 103, and the fourth raw wafer production line 104 are unloaded by the robotic unloading device 301 and transported by AGV trolley 302 to be stored in the buffer stack 303. Then, the raw wafers in the buffer stack 303 are placed onto the corresponding deep processing lines of the second raw wafer production line 102, the third raw wafer production line 103, and the fourth raw wafer production line 104 via AGV trolley 302 and robotic unloading device 306. The raw wafers from the second raw wafer production line 102, the third raw wafer production line 103, and the fourth raw wafer production line 104 enter the subsequent deep processing lines via AGV transfer modules, without conflicting with the direct roller conveyor mode.

[0060] Second embodiment:

[0061] In this embodiment, a five-line specification with one kiln is adopted, with a daily output of 2000t / d of raw slices; the raw slice production lines are the first raw slice production line 101, the second raw slice production line 102, the third raw slice production line 103, the fourth raw slice production line 104, and the fifth raw slice production line.

[0062] like Figure 1 , Figure 4 As shown, the first raw wafer production line 101, the third raw wafer production line 103, and the fifth raw wafer production line are connected to the deep processing line via a roller conveyor direct connection module, while the second raw wafer production line 102 and the fourth raw wafer production line 104 are connected to the deep processing line via an AGV transfer module. In this embodiment, the daily output of 2000 t / d is allocated to the five raw wafer production lines as follows: 400 t / d for the first raw wafer production line 101, 400 t / d for the second raw wafer production line 102, 400 t / d for the third raw wafer production line 103, 400 t / d for the fourth raw wafer production line 104, and 400 t / d for the fifth raw wafer production line.

[0063] Among them, the three deep processing lines corresponding to the first raw wafer production line 101, the third raw wafer production line 103, and the fifth raw wafer production line are 80m cover plate lines, and the capacity of the deep processing lines is higher than that of the raw wafer production lines. The two deep processing lines corresponding to the second raw wafer production line 102 and the fourth raw wafer production line 104 are 80m integrated lines, and the capacity of the deep processing lines is higher than that of the raw wafer production lines.

[0064] When in operation, only the "direct connection priority" mode is enabled: the roller conveyor direct connection mode is fully open, the AGV control system retrieves about 3% of the raw film quantity from the buffer stack 303 (including raw films that do not meet the cover plate quality but meet the back plate quality are unloaded) and places them on the first raw film production line 101, the third raw film production line 103 and the fifth raw film production line through the AGV trolley 302 and the robotic arm loading and unloading device 205.

[0065] When any of the first raw wafer production line 101, the third raw wafer production line 103, and the fifth raw wafer production line (such as...) Figure 1 When L1, L3, and Ln in the original wafer production line are shut down, the AGV transfer module handles 100% of the wafer scheduling on the first wafer production line 101, the third wafer production line 103, and the fifth wafer production line, with excess wafers entering the buffer stack 303. When the first wafer production line 101, the third wafer production line 103, and the fifth wafer production line are shut down, the AGV transfer module transfers wafers from the buffer stack 303 and places them onto the first wafer production line 101, the third wafer production line 103, and the fifth wafer production line via the AGV trolley 302 and the robotic loading / unloading device 205, completing the delivery of wafers to the subsequent deep processing lines. Correspondingly, when the second wafer production line 102, the fourth wafer production line 104, and their corresponding deep processing lines malfunction, the AGV transfer module can also perform reasonable scheduling to ensure stable wafer supply and flexible scheduling in this embodiment.

[0066] Raw wafers from the second raw wafer production line 102 and the fourth raw wafer production line 104 are unloaded by the robotic unloading device 301 and transported by AGV trolley 302 to be stored in the buffer stack 303. The raw wafers in the buffer stack 303 are then placed onto the corresponding deep processing lines of the second and fourth raw wafer production lines 102 and 104 via AGV trolley 302 and robotic unloading device 306. The raw wafers from the second and fourth raw wafer production lines 102 and 104 then enter the subsequent deep processing lines via AGV transfer modules, which does not conflict with the direct roller conveyor mode.

[0067] Third embodiment:

[0068] In this embodiment, a one-kiln-six-line specification is adopted, with a daily output of 2400t / d of raw slices; wherein the raw slice production lines are the first raw slice production line 101, the second raw slice production line 102, the third raw slice production line 103, the fourth raw slice production line 104, the fifth raw slice production line, and the sixth raw slice production line.

[0069] like Figure 1 , Figure 5As shown, the first raw wafer production line 101 and the sixth raw wafer production line are connected to the deep processing line via a roller conveyor direct connection module. The second raw wafer production line 102, the third raw wafer production line 103, the fourth raw wafer production line 104, and the fifth raw wafer production line are connected to the deep processing line via an AGV transfer module. In this embodiment, the daily output of 2400 t / d is allocated to the six raw wafer production lines as follows: the daily output of the first raw wafer production line 101 is 500 t / d, the daily output of the second raw wafer production line 102 is 350 t / d, the daily output of the third raw wafer production line 103 is 350 t / d, the daily output of the fourth raw wafer production line 104 is 350 t / d, the daily output of the fifth raw wafer production line is 350 t / d, and the daily output of the sixth raw wafer production line is 500 t / d.

[0070] Among them, the two deep processing lines corresponding to the first raw film production line 101 and the sixth raw film production line are 80m cover plate lines. At this time, the capacity of the deep processing lines is lower than that of the raw film production lines, and about 25% of the film needs to be removed during normal production. The six deep processing lines corresponding to the second raw film production line 102, the third raw film production line 103, the fourth raw film production line 104, and the fifth raw film production line are 60m integrated lines. At this time, the capacity of the deep processing lines is higher than that of the raw film production lines.

[0071] When in operation, the roller conveyor is in full-load mode. The AGV control system unloads about 25% of the raw sheets (including raw sheets that do not meet the cover plate quality but meet the back plate quality) from the first raw sheet production line 101 and the sixth raw sheet production line through the robotic loading and unloading device 205. The unloaded sheets are then diverted by the AGV trolley 302 and stored in the buffer stack 303.

[0072] When either the first raw wafer production line 101 or the sixth raw wafer production line's corresponding deep processing line stops production, the AGV transfer module handles 100% of the raw wafer scheduling on those two lines, with excess raw wafers entering the buffer stack 303. When either the first or sixth raw wafer production line stops production, the AGV transfer module retrieves raw wafers from the buffer stack 303 and places them onto the first or sixth raw wafer production lines via the AGV trolley 302 and the robotic loading / unloading device 205, completing the delivery of raw wafers to subsequent deep processing lines. Similarly, when the second, third, fourth, and fifth raw wafer production lines and their corresponding deep processing lines malfunction, the AGV transfer module can also perform reasonable scheduling to ensure stable wafer supply and flexible scheduling in this embodiment.

[0073] Raw wafers from the second, third, fourth, and fifth wafer production lines 102, 103, 104, and 306 are unloaded by the robotic unloading device 301 and transported by AGV trolleys 302 to be stored in the buffer stack 303. The wafers in the buffer stack 303 are then placed onto the corresponding deep processing lines of the second, third, fourth, and fifth wafer production lines via AGV trolleys 302 and robotic unloading devices 306. The wafers from these production lines then enter the subsequent deep processing lines via AGV transfer modules, without conflicting with the direct roller conveyor mode.

[0074] Fourth embodiment:

[0075] In this embodiment, a kiln with six production lines is adopted, with a daily output of 3000t / d of raw wafers; the raw wafer production lines are the first raw wafer production line 101, the second raw wafer production line 102, the third raw wafer production line 103, the fourth raw wafer production line 104, the fifth raw wafer production line, and the sixth raw wafer production line.

[0076] like Figure 1 , Figure 6 As shown, the first raw wafer production line 101, the second raw wafer production line 102, the fifth raw wafer production line, and the sixth raw wafer production line are connected to the corresponding deep processing lines via roller conveyor direct connection modules. The third raw wafer production line 103 and the fourth raw wafer production line 104 are connected to the deep processing lines via AGV transfer modules. In this embodiment, the daily output of 3000 t / d is allocated to the six raw wafer production lines as follows: 500 t / d for the first raw wafer production line 101, 500 t / d for the second raw wafer production line 102, 500 t / d for the third raw wafer production line 103, 500 t / d for the fourth raw wafer production line 104, 500 t / d for the fifth raw wafer production line, and 500 t / d for the sixth raw wafer production line.

[0077] Among them, the four deep processing lines corresponding to the first raw film production line 101, the second raw film production line 102, the fifth raw film production line, and the sixth raw film production line are 80m integrated lines. At this time, the capacity of the deep processing lines is higher than that of the raw film production lines, and about 25% of the film needs to be processed during normal production. The five deep processing lines corresponding to the third raw film production line 103 and the fourth raw film production line 104 are 60m integrated lines or 80m integrated lines.

[0078] When in operation, only the "direct connection priority" mode is enabled: the roller conveyor direct connection mode is fully open, the AGV control system retrieves about 25% of the raw film quantity from the buffer stack 303 (including raw films that do not meet the cover plate quality but meet the back plate quality are unloaded) and places them on the first raw film production line 101, the second raw film production line 102, the fifth raw film production line, and the sixth raw film production line through the AGV trolley 302 and the robotic arm loading and unloading device 205.

[0079] When any of the deep processing lines corresponding to the first raw wafer production line 101, the second raw wafer production line 102, the fifth raw wafer production line, or the sixth raw wafer production line are shut down, the AGV transfer module takes over 100% of the raw wafer scheduling for these production lines, with excess raw wafers entering the buffer stack 303. When the first, second, fifth, and sixth raw wafer production lines are shut down, the AGV transfer module retrieves raw wafers from the buffer stack 303 and places them onto the first, second, fifth, and sixth raw wafer production lines via AGV carts 302 and robotic loading / unloading devices 205, completing the transfer of raw wafers to subsequent deep processing lines. Correspondingly, when the third raw wafer production line 103, the fourth raw wafer production line 104, and their corresponding deep processing lines (such as...) are shut down, the AGV transfer module also handles the shutdown of these production lines. Figure 1 When L3 and L4 in the process fail, the AGV transfer module can be used for reasonable scheduling to ensure stable chip supply and flexible scheduling in this embodiment.

[0080] Raw wafers from the third raw wafer production line 103 and the fourth raw wafer production line 104 are unloaded by the robotic unloading device 301 and transported by AGV trolley 302 to be stored in the buffer stack 303. The raw wafers in the buffer stack 303 are then placed onto the corresponding deep processing lines of the third and fourth raw wafer production lines 103 and 104 via AGV trolley 302 and robotic unloading device 306. The raw wafers from the third and fourth raw wafer production lines 103 and 104 then enter the subsequent deep processing lines via AGV transfer modules, which does not conflict with the direct roller conveyor mode.

[0081] In the above embodiments, the only difference between the 60m and 80m integrated production lines is the length of the equipment lines. This difference in length results in a different number of glass panes being transported, and the 80m integrated production line has a higher capacity than the 60m integrated production line. (Appendix) Figure 1 In this context, n represents the nth raw wafer production line, L1 represents the deep processing line corresponding to the first raw wafer production line 101, L2 represents the deep processing line corresponding to the second raw wafer production line 102, L3 represents the deep processing line corresponding to the third raw wafer production line 103, L4 represents the deep processing line corresponding to the fourth raw wafer production line 104, and Ln represents the deep processing line corresponding to the nth raw wafer production line.
