Description

Technical Field

[0001] This invention relates to the field of photovoltaic cell flower basket production technology, and in particular to a photovoltaic flower basket transmission buffer device and its working method. Background Technology

[0002] Photovoltaic cells (also known as solar cells) are semiconductor materials that convert solar energy into electrical energy. They are typically made of silicon (such as monocrystalline or polycrystalline silicon). They work based on the photovoltaic effect, where light shining on the surface of the cell excites electrons to flow, generating an electric current. This technology is widely used in solar power generation. A photovoltaic support basket (or photovoltaic mounting system) refers to a structure used to support photovoltaic cells, helping them to be installed and secured in various environments. The name "basket" is descriptive because its shape resembles a flower basket, used to support multiple photovoltaic cell modules.

[0003] In the photovoltaic cell production process, if equipment malfunctions, the baskets of cells produced in the previous stage need to be manually removed and transported to nitrogen cabinets for storage to prevent prolonged exposure to air from affecting their efficiency and yield. However, in a factory-scale mass production environment, due to the large output of cells and the large number of baskets, manual handling takes up too much time and is labor-intensive. Moreover, the baskets need to be stored in multiple nitrogen cabinets, occupying a lot of space, making basket storage very inconvenient. Summary of the Invention

[0004] This invention provides a photovoltaic flower basket transmission buffer device and its working method, which can solve the problem of inconvenient flower basket storage in the event of system downtime in the prior art.

Both the flower basket inlet and the flower basket outlet are provided with automatic sealing doors. The storage room is equipped with an inflation device, which is used to fill the storage room with nitrogen until the nitrogen content in the storage room reaches a preset concentration, so that the internal space of the storage room simulates a nitrogen environment suitable for storing flower baskets.

[0006] Preferably, it also includes a main frame that divides into several storage compartments, and the main frame is connected to a sealing plate for sealing the storage compartments.

[0007] Preferably, the main frame is connected to two monitoring instruments, which are used to monitor oxygen content.

[0008] Preferably, the two monitoring devices are located outside the storage room and inside the storage room, respectively.

[0009] Preferably, a conveyor belt is provided between the preceding device and the following device, the conveyor belt being used to transport the flower basket in the preceding device to the following device, and passing through each of the storage rooms during the transport.

[0013] Preferably, the storage room is provided with an exhaust pipe, and the exhaust pipe is equipped with an exhaust butterfly valve.

[0014] A method for operating a photovoltaic flower basket transmission buffer device includes: Determine whether the preceding and following devices have failed; In the event of a system failure, the flower basket delivery is stopped, the automatic sealing door is closed, and nitrogen is introduced into the storage room via the inflation device. A nitrogen concentration value is preset, and the nitrogen filling amount is adjusted based on the oxygen content monitored by the monitoring instrument inside the storage room so that the nitrogen content in the storage room reaches the preset nitrogen concentration value. Remove the flower baskets from the preceding and following equipment to the external nitrogen tank; Repair the malfunctioning equipment until it is back in normal use. Stop filling the storage room with nitrogen, fill the storage room with air and open the exhaust butterfly valve until the oxygen content monitored by the monitor inside the storage room is the same as that monitored by the monitor outside the storage room.

[0020] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] like Figure 1 As shown in the figure, an embodiment of the present invention provides a photovoltaic flower basket transmission buffer device, which is connected between a preceding device and a following device. A conveyor belt 4 is provided between the preceding device and the following device. The conveyor belt 4 is used to transport the flower basket in the preceding device to the following device, and the flower basket passes through the photovoltaic flower basket transmission buffer device during the transportation.

[0022] like Figure 2 As shown, the photovoltaic flower basket transmission buffer device includes: a main frame 8, which divides into several storage compartments, which are connected end-to-end and interconnected. A sealing plate is connected to the main frame 8, serving as the wall of the storage compartments for sealing. The number of storage compartments is determined based on the actual production scale.

[0023] Among them, such as Figures 3-4As shown, a flower basket inlet is provided at the connection between the storage room and the preceding equipment, and a flower basket outlet is provided at the connection between the storage room and the following equipment. Both the flower basket inlet and outlet are equipped with automatic sealing doors 1 to control the opening and closing of the flower basket inlet and outlet. If one or both of the preceding and following equipment fail, the automatic sealing doors 1 can close to store the flower basket in the storage room, preventing the temporarily stored flower basket from being unusable during equipment maintenance.

[0024] like Figure 1 , Figure 5 As shown, the main frame 8 is connected to two monitoring instruments 3, located outside and inside the storage room respectively, for monitoring the oxygen content inside and outside the storage room. The storage room is equipped with an exhaust pipe, which is fitted with an exhaust butterfly valve 5 for venting.

[0025] like Figure 5 As shown, the storage room is equipped with an inflation device 2, which is used to fill the storage room with nitrogen until the nitrogen content in the storage room reaches a preset concentration, so that the internal space of the storage room simulates a nitrogen environment suitable for flower basket storage. Since the flower basket contains battery cells, the battery cells need to be stored in a nitrogen environment to avoid damage caused by prolonged contact with air. Therefore, a nitrogen environment is a necessary environment for the storage and buffering of the flower basket.

[0026] Specifically, the inflation device 2 includes multiple gas distribution plates distributed inside the storage chamber. These plates are connected to an external gas source and are used to evenly distribute the gas inside the storage chamber. One group of gas distribution plates is connected to a nitrogen source, while another group is connected to a blower to inject air into the storage chamber.

[0027] In this embodiment, when the equipment malfunctions and the flower baskets need to be stored and buffered in the storage room, the inflation device 2 distributes nitrogen evenly in the storage room through the gas distribution plate. When the equipment is in normal use, nitrogen filling of the storage room is stopped, and air is used instead, until the oxygen content inside and outside the storage room is the same, before the flower baskets can continue to be delivered to the subsequent equipment.

[0028] It should be noted that, as Figures 3-4 As shown, each storage compartment has an access port on one side of the conveyor belt 4, and the access port is equipped with a manually sealed door 6. The main frame 8 is equipped with several safety locks 7 to control the opening and closing of the manually sealed doors 6. Each safety lock 7 corresponds to a manually sealed door 6. Before opening the manually sealed door 6, it is necessary to ensure that the oxygen content inside the storage compartment is the same as that of the external environment.

[0029] The inventors discovered that in existing technologies, when either the preceding or following equipment is down, manual removal of the baskets produced in the preceding process and their transfer to nitrogen cabinets for storage are required. While this buffering method is suitable for smaller production scales, for large-scale factories, the large volume of produced solar cells necessitates buffering. The solar cells remaining in the baskets while awaiting equipment repair necessitates significant manpower and resources to move these baskets to the nitrogen cabinets, increasing labor costs and the high cost of nitrogen cabinets. Furthermore, a large number of nitrogen cabinets represent a substantial portion of operating costs. In particular, downtime is a rare occurrence in industrial production. During daily production, nitrogen cabinets remain idle, resulting in low utilization and occupying considerable space, further reducing solar cell production efficiency and factory output.

[0030] Given the problems existing in the current technology, it is generally thought that when the equipment is down, the production line in the workshop cannot continue to produce. If the workshop is sealed and filled with nitrogen to simulate the storage environment of a nitrogen cabinet, the flower baskets can also be temporarily stored and cached.

[0031] However, while this method is theoretically feasible, many factors need to be considered in practice. First, the workshop is a large and complex space, making it difficult to completely seal off the entire area. Second, even if the challenging task of sealing the workshop is accomplished, filling the entire workshop with nitrogen would incur extremely high costs, which would still be detrimental to production. Furthermore, the workshop contains not only various equipment on the production line but also operators, and a high-nitrogen environment would inevitably pose safety risks to the operators.

[0032] In this application, when both the preceding and following equipment are operating normally, the conveyor belt 4 transports the flower baskets produced by the preceding equipment and the solar cells inside the flower baskets to the following equipment for processing through each storage room. When the preceding or following equipment malfunctions and needs maintenance, or when some components in the equipment need to be maintained or replaced, it is necessary to store the flower baskets and the solar cells they carry. First, the equipment before and after the photovoltaic flower basket transport buffer device is shut down, and then the conveyor belt 4 is shut down, so that the equipment and the flower baskets on the conveyor belt are in a stationary state. Then, the automatic sealing door 1 and all manual sealing doors 6 are closed to keep the storage room sealed. The gas filling device 2 distributes nitrogen evenly to several storage rooms through the gas equalization plate. The monitoring instrument 3 inside the storage room monitors the oxygen content and controls the flow rate of nitrogen filling based on the oxygen content monitoring data until the nitrogen content in the storage room reaches the standard (i.e., the nitrogen reaches the preset concentration). The internal space of the storage room simulates a nitrogen environment suitable for flower basket storage. At this point, nitrogen filling is stopped, allowing the several baskets and the battery cells inside the baskets between the preceding and following equipment to be cached in their respective storage compartments. Compared to the existing technology of manually transporting the baskets to the nitrogen cabinet, this caching device can conveniently enable the baskets to be stored and cached in situ.

[0033] After the equipment that has been shut down is repaired, the air filling device 2 distributes air evenly to several storage compartments through the air distribution plate, and the exhaust butterfly valve 5 is opened. Two monitoring instruments 3 simultaneously monitor the oxygen content inside and outside the storage compartments. When the oxygen content inside the storage compartment is the same as the oxygen content outside, the automatic sealing door 1 is opened, and the conveyor belt 4 continues to work to transport the flower baskets.

[0034] If there are unfinished flower baskets in the preceding or following equipment, since the flower baskets are not yet in the buffer device, they can be quickly moved manually to an external nitrogen cabinet for storage. The number of such flower baskets is extremely small, and this non-batch handling will not incur significant economic or labor costs. It also eliminates the need to maintain multiple nitrogen cabinets, avoiding the occupation of large amounts of space. This achieves a flexible combination of existing technology and this technical solution, effectively improving the space utilization rate of the workshop.

[0035] In this application, the flower basket transport buffer device has nitrogen filling, venting, sealing and monitoring functions, so that the flower basket can be buffered in place and can be quickly switched to nitrogen state during buffering, without the need for manual batch handling.

[0036] When the storage basket is used for caching within several storage compartments, the simulated nitrogen environment prevents air from affecting the efficiency and yield of the solar cells within the basket, and avoids product quality degradation due to prolonged equipment downtime for maintenance. Furthermore, the basket allows for in-situ storage caching, effectively reducing caching complexity and saving space compared to nitrogen cabinets prepared for emergencies.

[0037] In one implementation, such as Figure 6 As shown in the figure, the working method of a photovoltaic flower basket transmission buffer device provided in this embodiment of the invention includes: S1. Determine if the preceding and following devices have failed. If neither the preceding nor following device has failed, proceed to S2. If either or both the preceding and following devices have failed, proceed to S3.

[0038] S2. Keep the manual sealing door 6 open to facilitate observation of the flower basket and the conveying status of the battery cells it carries, as well as to facilitate the detection of the working status of the components in the conveyor belt 4 and the storage room. If any abnormality occurs, maintenance and repair can be carried out in a timely manner.

[0039] S3. In case of system failure, stop the basket conveying, close the automatic sealing door 1, and fill the storage room with nitrogen through the inflation device 2. The inflation device 2 delivers nitrogen supplied by the external nitrogen source to each storage room through the gas distribution plate, so that the nitrogen concentration in the storage room gradually increases.

[0040] If the manual sealing door 6 is open, it needs to be closed simultaneously and secured with a safety door lock 7 to prevent accidental opening of the manual sealing door 6 and to prevent the filled nitrogen from leaking out.

[0041] S31. A nitrogen concentration value is preset. Based on the oxygen content monitored by the monitoring instrument 3 inside the storage room, the nitrogen filling amount is adjusted. That is, the flow rate of nitrogen filling is controlled according to the oxygen content monitoring data so that the nitrogen content in the storage room reaches the preset nitrogen concentration value.

[0042] S32. If there are unfinished flower baskets in the preceding or following equipment, remove the flower baskets from the preceding and following equipment to an external nitrogen cabinet. This small-scale handling will not cause significant economic or labor costs, and there is no need to keep multiple nitrogen cabinets on hand, thus achieving a flexible combination of existing technology and the technical solution of this application.

[0043] S33. Repair the malfunctioning equipment to restore it to normal operating condition and stop filling the storage room with nitrogen. Fill the storage room with air. The air filling device 2 delivers external air to each storage room through the air distribution plate. Open the exhaust butterfly valve 5 until the oxygen content monitored by the monitoring instrument 3 inside the storage room is the same as the oxygen content monitored by the monitoring instrument 3 outside the storage room (i.e., the oxygen concentration inside the storage room returns to normal). Then stop filling the air.

[0044] S34. Open the automatic sealing door 1 and resume the conveyor belt 4 to allow the flower basket to continue to be conveyed to the subsequent equipment.

[0045] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
