Description

Technical Field

[0001] This application relates to the technical field of battery cell storage devices, and more specifically, to a battery cell storage cabinet. Background Technology

[0002] As a high-precision semiconductor device, solar cells are extremely susceptible to oxidation and contamination on their surface.

[0003] In some technical solutions, failure to seal the solar cells in a timely manner can lead to oxidation of the cells by the outside air, resulting in a slight decrease in the power of the cells. Currently, the produced solar cells are generally transported on open shelves. As time goes on, the power of the solar cells will decrease, affecting their subsequent use.

[0004] While nitrogen protection can significantly improve the storage quality of solar cells, existing nitrogen-protected storage cabinets present some operational inconveniences in practical use. For example, the design of some storage cabinets makes it difficult to insert and remove the storage baskets (containers for solar cells), requiring considerable time and manpower.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application.

[0024] like Figures 1 to 7 As shown, the battery cell storage cabinet in Embodiment 1 includes a cabinet assembly 10 and a conveying assembly 20. The cabinet assembly 10 includes a cabinet structure 11 and a door opening / closing structure 12. The cabinet structure 11 has a placement opening, and the door opening / closing structure 12 is correspondingly positioned to the placement opening. The cabinet structure 11 and the door opening / closing structure 12 form a receiving space 100. The cabinet structure 11 is provided with a first gas channel 200 connecting the exterior of the cabinet structure 11 and the receiving space 100. The conveying assembly 20 is disposed within the receiving space 100 and includes a drive device 21 and a transmission structure 22, with the transmission structure 22 connected to the drive device 21.

[0025] Applying the technical solution of Embodiment 1, the first gas channel 200 of the cabinet assembly 10 can achieve gas replacement, replacing the oxygen in the cabinet assembly 10 with a gas that is not easily oxidized, such as nitrogen. The conveying assembly 20 is located within the receiving space 100 and can easily move with the cabinet assembly 10. The conveying assembly 20 can conveniently transport the flower basket 400 into and from the receiving space 100 to the outside of the cabinet assembly 10, thus saving manpower and resources. The technical solution of this embodiment effectively solves the problems of easy oxidation of battery cells in existing battery cell storage cabinets by external air and the inconvenience of retrieving and placing battery cells.

[0026] like Figure 1 and Figure 2As shown, in the technical solution of Embodiment 1, the opening and closing door structure 12 includes a roller 121 and a roller shutter 122. The roller 121 is rotatably disposed on the top of the opening and closing door structure 12, and the roller shutter 122 has an open state where it is rolled up on the roller 121, or an open closed state where it is unfolded. The arrangement of the roller 121 and the roller shutter 122 makes the structure of the cabinet assembly 10 compact and occupies less space. For example, it can save transportation costs when loading and transporting. It should be noted that the bottom of the cabinet structure 11 in this embodiment has wheels, which facilitates the movement and handling of the cabinet assembly 10. The wheels are at a predetermined height from the bottom surface of the cabinet structure 11, which allows for forklifts to transfer the battery cell storage cabinet.

[0027] like Figure 3 and Figure 4 As shown, in the technical solution of Embodiment 1, the cabinet structure 11 includes a cabinet body 111 and a roller shutter closing frame 112. The roller shutter closing frame 112 is located circumferentially outside the placement opening of the cabinet body 111. The top of the roller shutter closing frame 112 has a roller shutter guide gap, and the inner sidewall of the roller shutter closing frame 112 has a roller shutter guide groove. The above structure facilitates the movement of the roller shutter door 122 along a predetermined trajectory, thereby sealing the accommodating space 100. It should be noted that the roller shutter guide groove is located on the other three inner sides of the roller shutter closing frame 112, and the upper part of the roller shutter closing frame 112, i.e., the aforementioned top, is the guide gap.

[0028] like Figure 7 As shown, in the technical solution of Embodiment 1, the cabinet structure 11 also includes a sealing ring 113. When the roller shutter door 122 is in the closed state, the sealing ring 113 is located between the roller shutter closing frame 112 and the roller shutter door 122. That is, the sealing ring 113 is embedded in the guide gap and guide groove, which provides a better sealing effect.

[0029] like Figure 7 As shown, in the technical solution of Embodiment 1, the sealing ring 113 has a sealing protrusion on the side facing the roller shutter 122 that cooperates with the roller shutter 122. This structure further improves the sealing performance. It should be noted that the sealing ring 113 can be made of silicone or rubber. The sealing protrusion facilitates the deformation of the sealing ring 113, making the sealing ring 113 fit more tightly with the roller shutter 122 and the roller shutter closing frame 112.

[0030] like Figures 1 to 5As shown, in the technical solution of Embodiment 1, the transmission structure 22 includes a mounting base 221, a driving wheel 222, a driven wheel 223, and a chain 224. Both the driving wheel 222 and the driven wheel 223 are rotatably mounted on the mounting base 221. The output end of the drive device 21 is connected to the driving wheel 222, and the chain 224 is sleeved on the circumferential outer side of the driving wheel 222 and the driven wheel 223. Chain transmission ensures that both the driving wheel 222 and the driven wheel 223 are in motion, which facilitates increased friction and improves the force applied to the flower basket. Figure 5 As shown, the driving wheel 222 includes a shaft, two middle wheels that are conveying wheels, and two side wheels that are sprockets that cooperate with the chain 224. The driven wheel 223 is the same as the driving wheel 222. The driving device 21 is a drive motor, and the output shaft of the drive motor is connected to the shaft. The rotation of the shaft drives the two sprockets of the driving wheel 222 to rotate, which in turn drives the chain 224 to move. The chain 224 drives the sprocket of the driven wheel 223 to rotate, which in turn drives the driven wheel 223 to rotate. There are multiple driven wheels 223, and the driving wheel 222 and multiple driven wheels 223 are arranged sequentially from the outside to the inside. The width of the flower basket 400 is matched with the width of the two conveyor wheels on the same rotating shaft. The flower basket 400 is placed on the two conveyor wheels of the drive wheel 222, and the operator lays it as flat as possible. The flower basket 400 moves inward under the friction of the conveyor wheels. As the flower basket 400 contacts the conveyor wheel of the driven wheel 223, its movement becomes increasingly smooth. Once the flower basket 400 is fully inside the receiving space 100, it is secured to the limiting plates on both sides of the transmission structure with bolts. Clips or ropes can also be used, but these will not be elaborated on here. When the flower basket 400 is removed, the drive motor reverses. It should be noted that when the flower basket 400 is halfway out, its center of gravity is outside the receiving space 100, requiring operator control for safety.

[0031] It should be noted that, depending on the needs of use, the flower basket 400 can be fixed inside the cabinet component 10.

[0032] like Figure 3 and Figure 4 As shown, in the technical solution of Embodiment 1, the cabinet structure 11 further includes a partition 114, which is horizontally arranged to divide the accommodating space 100 into multiple sub-accommodating spaces arranged vertically. This structure can fully utilize space and hold more flower baskets 400. It should be noted that the cabinet structure 11 in this embodiment includes a partition 114, dividing the accommodating space 100 into two sub-accommodating spaces. A sealing strip is provided between the partition 114 and the cabinet body 111 to ensure the independence of each sub-accommodating space. Each sub-accommodating space corresponds to multiple conveying components 20; in this embodiment, each sub-accommodating space corresponds to two conveying components 20, thus further maximizing space utilization.

[0033] like Figures 1 to 4 As shown, in the technical solution of Embodiment 1, the cabinet structure 11 is further provided with a second gas channel 300 connecting the exterior of the cabinet structure 11 and the accommodating space 100. Each sub-accommodating space corresponds to a first gas channel 200 and a second gas channel 300. Within the same sub-accommodating space, the first gas channel 200 is higher than the second gas channel 300. The first gas channel 200 is the nitrogen inlet channel, and the second gas channel 300 is the air or nitrogen outlet channel. Since the density of nitrogen is less than that of air, the first gas channel 200 is higher than the second gas channel 300, which helps to improve the gas replacement efficiency. Valves on the first gas channel 200 and the second gas channel 300 are provided as needed, and will not be described in detail here.

[0034] like Figures 1 to 4 As shown, in the technical solution of Embodiment 1, the battery cell storage cabinet also includes multiple oxygen detectors 30, with each sub-accommodation space equipped with an oxygen detector 30. The placement of the oxygen detectors 30 facilitates monitoring the degree of air replacement within each sub-accommodation space at any time.

[0035] It should be noted that the door opening and closing structure 12 also includes a roller motor, the output shaft of which is connected to the roller 121. The battery cell storage cabinet also includes a control component, which is electrically connected to the roller motor, drive motor, and oxygen detector 30. This facilitates the control of the battery cell storage cabinet and reduces the labor intensity of the operator. While the roller 121 can also be operated by an operator to open and close the door, this would require more effort and be less efficient.

[0036] In summary, the first gas channel 200 is equipped with an inlet valve, and the second gas channel 300 is equipped with an outlet valve. This embodiment provides a nitrogen-filled rack (battery cell storage cabinet) for transporting battery cells, solving the problem of power attenuation caused by oxidation of battery cells by external air when transporting battery cells using racks in the prior art. The roller shutter door 122 is used to open and close the cabinet structure 11. In use, the roller shutter door 122 can open one side opening of the rack body (cabinet structure 11) to facilitate the placement of battery cells into the rack body. After the battery cells are placed into the rack body, the roller shutter door closes one side opening of the rack body, forming a sealed space inside the rack body. Nitrogen is supplied from the outside, and nitrogen is filled into the rack body through the inlet valve. The outlet valve discharges the original oxygen inside the rack body. A gas detector (oxygen detector 30) detects the oxygen content inside the rack body, achieving efficient control of the oxygen content inside the rack body, thereby preventing oxidation of battery cells during transportation.

[0037] A partition 114 is fixed in the middle of the inner wall of the shelf body. A conveying device (conveyor assembly 20) is provided at the top of the partition 114 and the inner bottom of the shelf body. A flower basket 400 is provided at the top of the conveying device.

[0038] In this embodiment, the flower basket is used to store the battery cells, and the transport device facilitates the storage and movement of the flower basket.

[0039] To more efficiently control the oxygen content inside the shelving unit, two inlet valves and two outlet valves are installed, one above and one below the partition 114. The partition 114 divides the shelving unit into two sealed spaces. The inlet and outlet valves above the partition 114 allow for separate nitrogen filling of the upper sealed space; the inlet and outlet valves below the partition 114 allow for separate nitrogen filling of the lower sealed space. Simultaneous nitrogen filling of both spaces rapidly reduces the oxygen content inside the shelving unit, preventing oxidation of the battery cells before encapsulation.

[0040] The upper and lower side walls of the shelving unit are equipped with observation windows (windows 115). These windows are made of transparent material, such as transparent glass or transparent plastic. A digital oxygen detector is used, installed on the inner wall of the shelving unit near the observation windows for easy monitoring of oxygen levels. The digital oxygen detector detects oxygen levels and displays the values ​​on a screen. The observation windows facilitate observation of the internal conditions and oxygen levels.

[0041] A sealing strip is fixedly installed on the side of partition 114 near the roller shutter door. The sealing strip has a U-shaped cross-section. The sealing strip can play a sealing role, dividing the shelf body into two sealed spaces (separate storage spaces). The sealing strip can reduce gas leakage between the upper and lower sealed spaces.

[0042] like Figure 8 As shown, the difference between the technical solution of Embodiment 2 and Embodiment 1 is that both the driving wheel 222 and the driven wheel 223 are rollers, meaning there is no need to set up a separate conveyor wheel. The conveyor wheel is the larger diameter section in the middle of the rotating shaft. The larger diameter section in the middle is the conveying part, and the length of the conveying part is similar to the width of the basket 400. The outer surface of the larger diameter section in the middle is made of rubber, which can increase the friction and provide a certain buffering effect when the basket 400 comes into contact with the transmission structure 22. The outer wall of the conveying part can also be provided with a friction surface, such as a convex-concave structure.

[0043] like Figure 9As shown, the difference between the technical solution of Embodiment 3 and Embodiment 1 is that the first gas channel 200 and the second gas channel 300 are connected by a circulation pipeline, which is equipped with a valve and a delivery pump. When the oxygen level in the compartment detected by the oxygen detector 30 is within acceptable limits, the corresponding gas circulation system is activated. No external nitrogen is required, nor is air discharged (controlled by the valve). This promotes uniform gas distribution within the compartment and eliminates the need for excessive nitrogen replenishment and replacement. This saves costs and protects the environment by reducing nitrogen emissions.

[0044] like Figure 10 and Figure 11 As shown, the difference between the technical solution of Embodiment 4 and the technical solution of Embodiment 1 is that the cabinet structure 11 further includes a sieve plate. The sieve plate is located at the outlet of the first gas channel. Nitrogen gas enters the space enclosed by the sieve plate 116 and the cabinet body 111, and then enters the sub-accommodation space through the sieve holes. In this way, when the nitrogen gas enters the sub-accommodation space, the gas distribution is more uniform. The length direction of the sieve plate extends from the opening and closing door of the cabinet body 111 to the interior.
