Description

Technical Field

[0001] The present application belongs to the technical field of battery production, and in particular relates to a material storage device and a battery production line. Background Art

[0002] In some cases, the battery production line is equipped with a storage device, which can be used to store the components contained in the battery to supply other equipment in the battery production line. Since the storage space of the storage device is limited, personnel need to refill the storage device from time to time. However, during the period when the personnel refill the storage device, the storage device and other equipment in the battery production line may physically interact, which is prone to accidents, resulting in poor reliability of the storage device during the refilling period. Utility Model Content

[0003] The embodiments of the present application provide a material storage device and a battery production line, which are intended to solve the problem of poor reliability of the material storage device during material replenishment.

[0004] To achieve the above purpose, the technical solution adopted in the embodiment of the present application is:

[0005] In a first aspect, a storage device is provided, comprising:

[0006] A silo, one side of which is open, and the silo can reciprocate along a first direction between a feeding position and a replenishing position;

[0007] The protection mechanism includes a connected protection structure and a moving structure. The moving structure drives the protection structure to move along the second direction through the feeding position. The protection structure can cover the opening of the silo at the same position at the feeding position. The second direction intersects with the first direction.

[0008] The storage device provided in the embodiment of the present application can be used to supply materials to other equipment of the battery production line through the silo at the feeding position by moving the silo along the first direction to the feeding position, and making the mobile structure drive the protective structure to move away from the feeding position along the second direction to expose the opening of the silo. The storage device provided in the present embodiment can also be used to make the mobile structure drive the protective structure to move to the feeding position along the second direction, and make the silo move from the feeding position to the refilling position along the first direction, so that personnel can refill materials into the silo at the refilling position. In addition, during the period when personnel refill the silo, the protective structure can be used to isolate and block other equipment of the battery production line at the feeding position to isolate and block the physical interaction between the refilling silo and other equipment of the battery production line, thereby reducing the interactivity between the refilling silo and other equipment of the battery production line, reducing the probability of accidents during the refilling of the storage device, and improving the reliability of the storage device during the refilling period.

[0009] In some embodiments, the movable structure is disposed on a side of the protective structure facing away from the silo.

[0010] By adopting the above scheme, by arranging the mobile structure on the side of the protective structure facing away from the silo, on the one hand, the protective structure can be arranged relatively close to the silo, and the protective structure can effectively shield and isolate the opening of the silo at the feeding position, thereby improving the physical isolation effect of the protective structure at the feeding position, and facilitating the protective structure to reliably isolate and block the physical interaction between the silo and other equipment of the battery production line at the feeding position, and reducing the probability of accidents during the replenishment of the storage device, and improving the reliability of the storage device during the replenishment. On the other hand, the mobile structure can be arranged relatively far away from the silo, which can reduce the risk of interference between the mobile structure and the silo, facilitate the connection and transmission of the mobile structure and the protective structure, make the structural layout of the protective mechanism compact and reasonable, and improve the structural reliability and operational reliability of the protective mechanism.

[0011] In some embodiments, the protection structure includes at least one protection plate, and the protection plate is arranged parallel to the first direction and the second direction.

[0012] By adopting the above scheme, the protective structure can cover the opening of the silo at the same position at the feeding position through one or more protective plates arranged parallel to the first direction and the second direction to form a reliable and effective physical isolation barrier, thereby improving the physical isolation effect of the protective structure at the feeding position, and facilitating the protective structure to reliably isolate and block the physical interaction between the replenishing silo and other equipment in the battery production line at the feeding position, thereby reducing the probability of accidents during the replenishment of the storage device and improving the reliability of the storage device during the replenishment period.

[0013] In some embodiments, the protective structure includes a connecting plate, which is vertically arranged on a side of the protective plate facing the moving structure and connected to the moving structure.

[0014] By adopting the above solution, the protective structure can also use the connecting plate erected on the side of the protective plate facing the mobile structure as a connecting bridge between the protective plate and the mobile structure, thereby improving the connection convenience and connection reliability between the protective plate and the mobile structure, and improving the movement stability and movement reliability of the protective structure driven by the mobile structure. In addition, the structural design of the comprehensive protective plate and the connecting plate can also improve the overall structural stability and rigidity of the protective structure.

[0015] In some embodiments, an isolation strip is provided on at least one side of the protective plate along the second direction, and the isolation strip is bent relative to the protective plate toward the silo.

[0016] By adopting the above scheme, when the protective structure is in the feeding position, the protective structure can not only cover the opening of the silo in the same position in parallel through the protective plate; but also can bend the isolation strip arranged on at least one side of the protective plate along the second direction to fit the corresponding edge of the silo opening, so as to form a reliable and effective physical isolation barrier between the protective plate and the silo opening. Based on this, the physical isolation effect of the protective structure in the feeding position can be improved, and the protective structure can be convenient for the protective structure to reliably isolate and block the physical interaction between the silo for replenishment and other equipment of the battery production line at the feeding position, and the probability of accidents during the replenishment of the storage device can be reduced, and the reliability of the storage device during the replenishment can be improved. In addition, since the isolation strip is arranged on the side of the protective plate along the second direction, but not on the side of the protective plate along the first direction, the influence of the setting of the isolation strip on the movement of the silo along the first direction can be reduced. In addition, the setting of the comprehensive isolation strip can also improve the overall structural stability and rigidity of the protective structure.

[0017] In some embodiments, isolation strips are respectively disposed on two opposite sides of the protection plate along the second direction.

[0018] By adopting the above scheme, when the protective structure is in the feeding position, the protective structure can not only cover the opening of the silo in the same position in parallel through the protective plate; but also form a reliable and effective physical isolation barrier between the two wall portions of the corresponding silo along the second direction and the protective plate through the two isolation strips on the opposite sides of the protective plate. Based on this, the physical isolation effect of the protective structure in the feeding position can be improved, and the protective structure can be convenient for the protective structure to reliably isolate and block the physical interaction between the silo for replenishment and other equipment of the battery production line at the feeding position, reduce the probability of accidents during the replenishment of the storage device, and improve the reliability of the storage device during the replenishment. In addition, since the isolation strips are provided on the opposite sides of the protective plate along the second direction, the forces on both sides of the protective plate can be balanced, the risk of shaking or offsetting of the protective plate due to uneven force on one side can be reduced, the stability of the movement of the protective plate can be improved, and the stability of the state of the protective plate at the feeding position can be improved.

[0019] In some embodiments, the movable structure includes a drive and at least one guide component, the guide component includes a first slide rail extending along the second direction, and a slider slidably connected to the first slide rail, the drive is connected to one of the sliders and drives the slider to slide along the first slide rail, and the protective structure is installed on the slider.

[0020] By adopting the above scheme, the moving structure can be connected to the slider of one of the guide components through the driver, and drive the slider to slide along the corresponding first slide rail, thereby driving the protective structure and the sliders of each guide component to move synchronously. Based on this, the moving structure can realize the reciprocating movement of the protective structure along the second direction with a simplified and optimized structural design. In addition, the direct drive mode of the driver can reduce the error in the transmission process, realize the precise control of the moving position of the protective structure, and improve the movement accuracy of the protective structure. In addition, the first slide rail can guide and constrain the moving direction and moving stroke of the slider, and the slider can slide smoothly along the first slide rail, thereby reducing the resistance and friction of the protective structure when it moves, reducing the driving force required for the movement of the protective structure, and improving the stability of the protective structure during movement.

[0021] In some embodiments, the moving structure includes a plurality of guide components spaced apart along the first direction, and a protective plate is provided between two adjacent guide components.

[0022] By adopting the above scheme, multiple guide components spaced apart along the first direction can provide multiple stable support points for the movement of the protective structure, thereby dispersing the stress and vibration of the protective structure during movement, and enhancing the overall structural stability and reliability of the protective mechanism. On this basis, based on the setting of "a protective plate is provided between two adjacent guide components", it is convenient to build a connection between the protective plate and the sliders of the two adjacent guide components, which can improve the convenience of disassembly and assembly, integrity, and coordination between the protective structure and the mobile structure, and can modularize and optimize the structural design of the protective mechanism.

[0023] In some embodiments, there are two material bins, which are arranged side by side along the second direction, and the moving structure is configured to be able to drive the protective structure to move back and forth between the feeding positions of the two material bins along the second direction.

[0024] By adopting the above solution, two silos can be set up so that while one silo is being refilled or waiting for refilling, the other silo can continue to supply materials to other equipment on the battery production line. Based on this, it is convenient to realize non-stop material supply and uninterrupted material supply, reduce production downtime due to refilling, and improve the production efficiency of the battery production line.

[0025] Furthermore, the protective structure can be driven by the mobile structure to switch and move between the feeding positions of the two silos along the second direction, so as to isolate other equipment of the battery production line for any silo to be refilled via the protective structure, thereby reducing the interactivity between the silo to be refilled and other equipment of the battery production line during the refilling of any silo, reducing the probability of accidents during the refilling of any silo, and improving the reliability of the storage device during the refilling of any silo. Furthermore, the two silos, one for backup and the other for use, can share a protective mechanism, based on which the number of protective mechanisms can be reduced, the structure of the storage device can be simplified, the layout and space occupancy of the storage device can be compact and optimized, and the cost and energy consumption of the storage device can be reduced.

[0026] In some embodiments, the storage device includes at least one detection component, which includes two detectors, one of which is connected to the protective structure and moves synchronously with the protective structure, and the other of the two detectors is fixed to the open edge of the silo. The two detectors detect each other to determine the position of the protective structure relative to the silo.

[0027] By adopting the above scheme, during the movement of the protective structure to the feeding position of the silo, the two detectors of the detection assembly corresponding to the protective structure and the silo can be detected to detect whether "the protective structure has reached the feeding position of the silo" and "the protective structure is in place". Based on this, a confirmation mechanism for the position of the protective structure can be formed, which can facilitate the storage device and the battery production line to take corresponding actions and measures according to the confirmation of the position of the protective structure (for example, the silo can move normally to the refueling position to wait for refueling when the protective structure is in place, and for example, the silo can be restricted from moving and refueling when the protective structure is not in place, and for example, the silo can be moved to the refueling position to wait for refueling when the protective structure is not in place, but the battery production line will be shut down, etc.), so as to maintain and improve the operation reliability and use reliability of the storage device and the battery production line during the refueling of the silo.

[0028] In some embodiments, the material storage device includes at least one second slide rail, the second slide rail is extended along the first direction, and the material bin is slidably connected to the at least one second slide rail.

[0029] By adopting the above scheme, by making the material bin slidably connected to at least one second slide rail extending along the first direction, the material bin can be made into a drawer type, and the moving direction and moving stroke of the material bin can be guided and constrained via the second slide rail. Based on this, on the one hand, the material bin can be enabled to slide smoothly along the second slide rail, the resistance and friction during the movement of the material bin can be reduced, and personnel can easily, labor-savingly and quickly move the material bin to the feeding position or the replenishing position, which can improve the operational flexibility and convenience. On the other hand, the second slide rail can provide stable guidance and constraints for the movement of the material bin, which can improve the stability of the material bin during the movement, reduce the shaking or deviation of the material bin, and improve the reliability of the storage device.

[0030] In a second aspect, a battery production line is provided, comprising the material storage device provided in an embodiment of the present application.

[0031] By adopting the above solution, the battery production line can store the raw materials required for battery production by applying the storage device provided in the embodiment of the present application, and improve the reliability during the feeding and replenishing periods.

[0044] A battery may be the smallest unit for storing and outputting electrical energy, i.e., a battery cell. In some cases, a battery includes a housing, an electrode assembly, an insulating film, and a bottom support sheet. The electrode assembly is disposed in the housing. The insulating film is coated on the peripheral side and the bottom side of the electrode assembly to insulate and isolate the electrode assembly from the housing, and to reduce the risk of corrosion of the housing caused by direct contact between the electrode assembly and the housing. The bottom support sheet is disposed between the bottom side of the insulating film and the housing to strengthen the bottom of the insulating film and provide reliable support for the electrode assembly. Among them, the insulating film may be made of mylar (Mylar film or Mylar film).

[0045] Based on this, battery production lines are usually equipped with storage devices, which are used to store the components contained in the battery (such as insulating films, bottom support sheets, etc.) to supply materials to other equipment in the battery production line. Since the storage space of the storage device is limited, personnel need to refill the storage device from time to time. However, during the period when personnel are refilling the storage device, the storage device and other equipment in the battery production line (such as material retrieval equipment, etc.) may physically interact, which is prone to accidents, resulting in poor reliability of the storage device during the refilling period.

[0046] Therefore, some embodiments of the present application provide a storage device, which can be used to supply materials to other equipment of the battery production line through the silo at the feeding position by moving the silo along the first direction to the feeding position, and allowing the mobile structure to drive the protective structure to move away from the feeding position along the second direction to expose the opening of the silo. The storage device can also be used to facilitate personnel to refill materials into the silo at the refilling position by allowing the mobile structure to drive the protective structure to move to the feeding position along the second direction, and allowing the silo to move from the feeding position to the refilling position along the first direction. In addition, during the period when the personnel are refilling the silo, the protective structure can be used to isolate and block other equipment of the battery production line at the feeding position to isolate and block the physical interaction between the refilling silo and other equipment of the battery production line, thereby reducing the interactivity between the refilling silo and other equipment of the battery production line, reducing the probability of accidents during the refilling of the storage device, and improving the reliability of the storage device during the refilling period.

[0047] The material storage device disclosed in the embodiment of the present application can be used to store any raw materials, and can be particularly used to store raw materials required for battery production (such as insulating films, bottom support sheets and other components contained in the battery), and is particularly suitable for use in battery production lines.

[0048] The battery production line disclosed in the embodiment of the present application can be used to produce batteries, and one or more storage devices disclosed in the embodiment of the present application can be set. Among them, the battery can be the smallest unit for storing and outputting electrical energy, that is, a battery cell. The battery cell can be a secondary battery, and a secondary battery refers to a battery cell that can be activated by charging the active material after the battery cell is discharged and continues to be used. The battery can be a lithium-ion battery, a sodium-ion battery, a sodium-lithium-ion battery, a lithium metal battery, a sodium metal battery, a lithium-sulfur battery, a magnesium-ion battery, a nickel-hydrogen battery, a nickel-cadmium battery, a lead-acid battery, and the like. The battery can be cylindrical, flat, rectangular, or in other shapes, and the like. The battery can be packaged in different ways to form a cylindrical battery, a square battery, a soft-pack battery, and the like.

[0049] In order to illustrate the technical solution provided by the present application, the following is combined with specific drawings and embodiments, and a detailed description is given on “the material storage device is used in a battery production line to store the raw materials required for battery production”.

[0050] See also Figure 1 , Figure 2 Some embodiments of the present application provide a storage device 1, including a silo 10 and a protective mechanism 20. The silo 10 has an opening 11 on one side, and the silo 10 can reciprocate between a feeding position and a replenishing position along a first direction x. The protective mechanism 20 includes a connected protective structure 21 and a moving structure 22, and the moving structure 22 drives the protective structure 21 to move through the feeding position along a second direction y. The protective structure 21 can cover the opening 11 of the silo 10 at the same position at the feeding position. The second direction y intersects the first direction x.

[0051] It should be noted that a storage space is formed in the silo 10, which can be used to store any raw materials, especially raw materials required for battery production (such as insulating films, bottom support sheets and other components included in the battery).

[0052] One side of the silo 10 has an opening 11, which is convenient for taking and placing raw materials into the silo 10 through the opening 11. For example, the material taking equipment of the battery production line can take materials from the silo 10 through the opening 11, and for another example, a person can add raw materials to the silo 10 (i.e., refill) through the opening 11. The sides of the silo 10 other than the opening 11 are closed. Based on this, the storage space in the silo 10 can be physically isolated from the external space and other equipment of the battery production line in multiple directions, and the silo 10 can realize multiple protection for the raw materials stored therein, and the silo 10 can realize multiple protection for the hands of the person when the person is refilling the silo 10, thereby improving the protection and reliability of the silo 10, reducing the probability of accidents during the refilling of the storage device 1, and preliminarily improving the reliability of the storage device 1 during the refilling.

[0053] The structure, shape and size of the silo 10 can be set as needed. In some embodiments, the silo 10 includes a base plate 13 and at least three side plates 12, each side plate 12 is connected end to end in sequence and together form a cylindrical structure, the base plate 13 covers the same side of each side plate 12 along the gravity direction, the base plate 13 and each side plate 12 together enclose a storage space for storing raw materials, and the side of each side plate 12 away from the base plate 13 together encloses the opening 11 of the silo 10. In this way, the sides of the silo 10 except the opening 11 can be closed.

[0054] The silo 10 has the freedom to move back and forth along the first direction x. The silo 10 can be driven to move back and forth along the first direction x by manpower or electricity, so that the silo 10 moves between the feeding position and the refilling position. The silo 10 can supply materials to other equipment of the battery production line at the feeding position, that is, the material taking equipment of the battery production line can take materials from the silo 10 at the feeding position. The silo 10 can be refilled by personnel at the refilling position, that is, personnel can refill materials into the silo 10 at the refilling position. Based on this, since the feeding position and the refilling position are spaced apart along the first direction x, during the period when the personnel refill the silo 10, the refilled silo 10 can be spaced a certain distance from other equipment of the battery production line (such as the refilling equipment, etc.) to reduce the interactivity between the refilled silo 10 and other equipment of the battery production line, thereby reducing the probability of accidents during the refilling of the storage device 1 and improving the reliability of the storage device 1 during the refilling.

[0055] It should also be noted that the protection mechanism 20 includes a protection structure 21 and a moving structure 22 .

[0056] The moving structure 22 is connected to the protective structure 21, and the moving structure 22 can drive the protective structure 21 to move back and forth along the second direction y, so that the protective structure 21 can move through the feeding position of the silo 10. The second direction y intersects (for example, is perpendicular to) the first direction x, so that the moving path of the protective structure 21 and the moving path of the silo 10 have an intersection, and the intersection is located at the feeding position. The structure of the moving structure 22 can be designed in a variety of ways, for example, a hydraulic or pneumatic drive structure, a linear motor drive structure, an electric ball screw structure, etc. can be used.

[0057] The structure of the protective structure 21 can be designed in a variety of ways, for example, it can be a plate-like structure. When the protective structure 21 and the silo 10 are at the same feeding position, the protective structure 21 can cover and seal above the opening 11 of the silo 10, so that the protective structure 21 can be physically blocked between the opening 11 of the silo 10 and other equipment in the battery production line. Based on this, during the period when the silo 10 moves from the feeding position to the refilling position along the first direction x, and during the period when personnel refill the silo 10 at the refilling position, the protective structure 21 can maintain the state of "isolating and blocking other equipment in the battery production line at the feeding position", thereby isolating and blocking the physical interaction between the refilling silo 10 and other equipment in the battery production line, which can reduce the probability of accidents during the refilling of the storage device 1 and improve the reliability of the storage device 1 during the refilling period.

[0058] In summary, the storage device 1 provided in the embodiment of the present application can be used to supply materials to other equipment in the battery production line through the silo 10 at the feeding position by moving the silo 10 along the first direction x to the feeding position, and allowing the mobile structure 22 to drive the protective structure 21 along the second direction y away from the feeding position to expose the opening 11 of the silo 10. The storage device 1 provided in the embodiment can also be used to facilitate personnel to refill materials into the silo 10 at the refilling position by allowing the mobile structure 22 to drive the protective structure 21 to move along the second direction y to the feeding position, and allowing the silo 10 to move along the first direction x from the feeding position to the refilling position. Furthermore, while personnel are refilling the silo 10, the protective structure 21 can be used to isolate and block other equipment on the battery production line at the feeding position, so as to isolate and block the physical interaction between the refilled silo 10 and other equipment on the battery production line, thereby reducing the interactivity between the refilled silo 10 and other equipment on the battery production line, reducing the probability of accidents during the refilling of the storage device 1, and improving the reliability of the storage device 1 during the refilling.

[0059] See also Figure 1 In some embodiments of the present application, the movable structure 22 is disposed on a side of the protective structure 21 facing away from the silo 10 .

[0060] By adopting the above scheme, by arranging the mobile structure 22 on the side of the protective structure 21 facing away from the silo 10, on the one hand, the protective structure 21 can be arranged relatively close to the silo 10, so that the protective structure 21 can effectively shield and isolate the open 11 of the silo 10 at the feeding position, thereby improving the physical isolation effect of the protective structure 21 at the feeding position, and facilitating the protective structure 21 to reliably isolate and block the physical interaction between the silo 10 for replenishment and other equipment of the battery production line at the feeding position, thereby reducing the probability of accidents during the replenishment of the storage device 1, and improving the reliability of the storage device 1 during the replenishment. On the other hand, the mobile structure 22 can be arranged relatively far away from the silo 10, which can reduce the risk of interference between the mobile structure 22 and the silo 10, facilitate the connection and transmission of the mobile structure 22 and the protective structure 21, make the structural layout of the protective mechanism 20 compact and reasonable, and improve the structural reliability and operational reliability of the protective mechanism 20.

[0061] Of course, in other embodiments, the movable structure 22 may be disposed on a side of the protective structure 21 facing the silo 10 , or disposed on a peripheral side of the protective structure 21 .

[0062] See also Figure 1 , Figure 2 In some embodiments of the present application, the protective structure 21 includes at least one protective plate 211, and the protective plate 211 is arranged parallel to the first direction x and the second direction y.

[0063] It should be noted that, in the protection structure 21, one or more protection plates 211 may be provided. The plate surface of the protection plate 211 is parallel to the first direction x and parallel to the second direction y. When the protection structure 21 is in the feeding position, the protection structure 21 can cover the opening 11 of the silo 10 in the same position through one or more protection plates 211 in parallel.

[0064] By adopting the above scheme, the protective structure 21 can cover the opening 11 of the silo 10 at the same position at the feeding position through one or more protective plates 211 arranged parallel to the first direction x and the second direction y, so as to form a reliable and effective physical isolation barrier, thereby improving the physical isolation effect of the protective structure 21 at the feeding position, and facilitating the protective structure 21 to reliably isolate and block the physical interaction between the silo 10 being replenished and other equipment in the battery production line at the feeding position, thereby reducing the probability of accidents during the replenishment of the storage device 1 and improving the reliability of the storage device 1 during the replenishment.

[0065] Of course, in other embodiments, the plate surface of the protection plate 211 may be slightly inclined with respect to the first direction x or the second direction y.

[0066] See also Figure 1 , Figure 2 In some embodiments of the present application, the protective structure 21 includes a connecting plate 212 , which is erected on a side of the protective plate 211 facing the moving structure 22 and connected to the moving structure 22 .

[0067] It should be noted that the connecting plate 212 is vertically arranged on the side of the protective plate 211 facing the movable structure 22, that is, the connecting plate 212 is connected to the side of the protective plate 211 facing the movable structure 22, and the connecting plate 212 and the protective plate 211 are arranged at an angle. Among them, on the side of the protective plate 211 facing the movable structure 22, the connecting plate 212 can be arranged at any position of the protective plate 211 as required, such as the end, middle, etc. of the protective plate 211 along the first direction x. The connecting plate 212 and the protective plate 211 can be connected as a whole or as a separate body. The angle between the connecting plate 212 and the protective plate 211 can be set as required, for example, it can be a right angle (that is, the connecting plate 212 is perpendicular to the protective plate 211).

[0068] By adopting the above solution, the protective structure 21 can also use the connecting plate 212 erected on the side of the protective plate 211 facing the mobile structure 22 as a connecting bridge between the protective plate 211 and the mobile structure 22, thereby improving the connection convenience and connection reliability between the protective plate 211 and the mobile structure 22, and improving the movement stability and movement reliability of the protective structure 21 driven by the mobile structure 22. In addition, the structural design of the comprehensive protective plate 211 and the connecting plate 212 can also improve the overall structural stability and rigidity of the protective structure 21.

[0069] Of course, in other embodiments, the connecting plate 212 may be omitted from the protection structure 21 , so that the protection plate 211 is directly connected to the moving structure 22 .

[0070] See also Figure 1 , Figure 2 In some embodiments of the present application, an isolation strip 213 is provided on at least one side of the protective plate 211 along the second direction y, and the isolation strip 213 is bent relative to the protective plate 211 toward the silo 10.

[0071] It should be noted that the protective plate 211 is provided with an isolation bar 213 on one side along the second direction y; or, the protective plate 211 is provided with isolation bars 213 on both opposite sides along the second direction y. The isolation bar 213 is a strip-shaped structure extending along the first direction x. The isolation bar 213 and the protective plate 211 can be connected in one piece or in a separate piece.

[0072] The isolation bar 213 is bent relative to the protective plate 211 toward the silo 10, that is, the isolation bar 213 is erected on the side of the protective plate 211 facing the silo 10, and the isolation bar 213 is arranged at an angle with the protective plate 211. The angle between the isolation bar 213 and the protective plate 211 can be set as required, for example, it can be a right angle (that is, the isolation bar 213 is perpendicular to the protective plate 211).

[0073] By adopting the above scheme, when the protective structure 21 is in the feeding position, the protective structure 21 can not only cover the opening 11 of the silo 10 in the same position in parallel through the protective plate 211; but also can bend the isolation strip 213 arranged on at least one side of the protective plate 211 along the second direction y to fit the corresponding edge of the opening 11 of the silo 10, so as to form a reliable and effective physical isolation barrier between the protective plate 211 and the opening 11 of the silo 10. Based on this, the physical isolation effect of the protective structure 21 in the feeding position can be improved, and the protective structure 21 can be convenient for the protective structure 21 to reliably isolate and block the physical interaction between the silo 10 being refilled and other equipment of the battery production line at the feeding position, which can reduce the probability of accidents during the refilling of the storage device 1 and improve the reliability of the storage device 1 during the refilling. Furthermore, since the isolation strips 213 are disposed on the side of the protective plate 211 along the second direction y, but not on the side of the protective plate 211 along the first direction x, the effect of the isolation strips 213 on the movement of the silo 10 along the first direction x can be reduced. Furthermore, the configuration of the isolation strips 213 can also improve the overall structural stability and rigidity of the protective structure 21.

[0074] Of course, in other embodiments, the protection structure 21 may omit the isolation strip 213 and only cover the opening 11 of the silo 10 at the same position in parallel via the protection plate 211 .

[0075] See also Figure 1 , Figure 2 In some embodiments of the present application, isolation strips 213 are respectively provided on two opposite sides of the protection plate 211 along the second direction y.

[0076] It should be noted that the protection plate 211 is provided with isolation bars 213 on opposite sides along the second direction y, and each isolation bar 213 is bent relative to the protection plate 211 toward the silo 10. The protection plate 211 and the two isolation bars 213 on opposite sides thereof can form a cap-like structure.

[0077] When the protective structure 21 is in the feeding position, the protective plate 211 can cover the opening 11 of the silo 10 in the same position in parallel, and the two isolation strips 213 on the opposite sides of the protective plate 211 correspond one-to-one to the two walls of the corresponding silo 10 (i.e., the silo 10 in the same position) along the second direction y. Among them, "the correspondence between the isolation strips 213 and the silo 10 wall" can mean that the isolation strips 213 are precisely aligned to the top of the silo 10 wall, or that the isolation strips 213 correspond to the area above the silo 10 wall and biased to the outside of the silo 10 wall, or that the isolation strips 213 correspond to the area above the silo 10 wall and biased to the outside of the silo 10 wall, that is, "the correspondence between the isolation strips 213 and the silo 10 wall" should be understood in a broad sense, and precise alignment is not required.

[0078] By adopting the above scheme, when the protective structure 21 is in the feeding position, the protective structure 21 can not only cover the opening 11 of the silo 10 in the same position in parallel through the protective plate 211; but also form a reliable and effective physical isolation barrier between the two wall portions of the corresponding silo 10 along the second direction y and the protective plate 211 through the two isolation strips 213 on the opposite sides of the protective plate 211. Based on this, the physical isolation effect of the protective structure 21 in the feeding position can be improved, and the protective structure 21 can be convenient for the protective structure 21 to reliably isolate and block the physical interaction between the silo 10 being refilled and other equipment in the battery production line at the feeding position, which can reduce the probability of accidents during the refilling of the storage device 1 and improve the reliability of the storage device 1 during the refilling. Furthermore, since isolation strips 213 are provided on opposite sides of the protective plate 211 along the second direction y, the forces on both sides of the protective plate 211 can be balanced, thereby reducing the risk of shaking or shifting of the protective plate 211 due to uneven force on one side, improving the movement stability of the protective plate 211, and improving the state stability of the protective plate 211 at the feeding position.

[0079] Of course, in other embodiments, the isolation strip 213 may be provided only on one side of the protection plate 211 along the second direction y.

[0080] See also Figure 1 , Figure 2 In some embodiments of the present application, the movable structure 22 includes a driver 221 and at least one guide component 222, the guide component 222 includes a first slide rail 2221 extending along the second direction y, and a slider 2222 slidably connected to the first slide rail 2221, the driver 221 is connected to one of the sliders 2222, and drives the slider 2222 to slide along the first slide rail 2221, and the protective structure 21 is installed on the slider 2222.

[0081] It should be noted that in the mobile structure 22, one or more guide components 222 may be provided. Each guide component 222 includes a first slide rail 2221 and at least one slider 2222. The first slide rail 2221 is extended along the second direction y, and the slider 2222 is slidably connected to the first slide rail 2221. The protective structure 21 is installed on the slider 2222 of each guide component 222.

[0082] The driver 221 is connected to a slider 2222 of one of the guide assemblies 222, and the driver 221 can drive the slider 2222 connected thereto to slide along the corresponding first slide rail 2221, so as to drive the protection structure 21 and other sliders 2222 to move synchronously. The driver 221 can be, but is not limited to, a cylinder, a motor, etc.

[0083] By adopting the above scheme, the mobile structure 22 can be connected to the slider 2222 of one of the guide components 222 through the driver 221, and drive the slider 2222 to slide along the corresponding first slide rail 2221, thereby driving the protective structure 21 and the sliders 2222 of each guide component 222 to move synchronously. Based on this, the mobile structure 22 can drive the protective structure 21 to move back and forth along the second direction y with a simplified and optimized structural design. In addition, the direct driving mode of the driver 221 can reduce the error in the transmission process, realize the precise control of the moving position of the protective structure 21, and improve the moving accuracy of the protective structure 21. In addition, the first slide rail 2221 can guide and constrain the moving direction and moving stroke of the slider 2222, and the slider 2222 can slide smoothly along the first slide rail 2221, thereby reducing the resistance and friction force when the protective structure 21 moves, reducing the driving force required for the movement of the protective structure 21, and improving the stability of the protective structure 21 during the movement.

[0084] Of course, in other embodiments, the moving structure 22 may adopt other structural designs, such as an electric ball screw structure, etc.

[0085] See also Figure 1 , Figure 2 In some embodiments of the present application, the moving structure 22 includes a plurality of guide components 222 spaced apart along the first direction x, and a protective plate 211 is provided between two adjacent guide components 222 .

[0086] It should be noted that the plurality of guide components 222 of the mobile structure 22 are arranged at intervals along the first direction x. A protective plate 211 is provided between each two adjacent guide components 222. Figure 1 , Figure 2As shown, in some embodiments, three guide assemblies 222 are provided, and the three guide assemblies 222 are spaced apart along the first direction x. The protective structure 21 includes two protective plates 211 , and a protective plate 211 is installed between each two adjacent guide assemblies 222 . The protective plate 211 is installed on the slider 2222 and moves synchronously with the slider 2222 .

[0087] By adopting the above scheme, multiple guide components 222 arranged at intervals along the first direction x can provide multiple stable support points for the movement of the protective structure 21, thereby dispersing the stress and vibration of the protective structure 21 during the movement, and enhancing the overall structural stability and reliability of the protective mechanism 20. On this basis, based on the setting of "a protective plate 211 is provided between two adjacent guide components 222", it is convenient to build the connection between the protective plate 211 and the sliders 2222 of the two adjacent guide components 222, which can improve the convenience of disassembly and assembly, integrity, and coordination between the protective structure 21 and the mobile structure 22, and can modularize and optimize the structural design of the protective mechanism 20.

[0088] Of course, in other embodiments, the movable structure 22 may include only one guide assembly 222 , and the protective structure 21 may be directly mounted on the slider 2222 of the guide assembly 222 .

[0089] Of course, in other embodiments, the movable structure 22 may include one or more guide components 222 , and only one protective plate 211 of the protective structure 21 may be provided, and the protective plate 211 may be installed on the slider 2222 of each guide component 222 .

[0090] See also Figure 1 In some embodiments of the present application, there are two silos 10, and the two silos 10 are arranged side by side along the second direction y. The moving structure 22 is configured to drive the protective structure 21 to move back and forth between the feeding positions of the two silos 10 along the second direction y.

[0091] It should be noted that there are two silos 10, and the two silos 10 are used to store the same raw material, so that the two silos 10 can be used in a standby mode, that is, when one silo 10 is in a feeding state, the other silo 10 can be in a feeding state. Figure 1 As shown, there are two storage devices 1, the two silos 10 of the storage device 1 on the left are both used to store insulating films and one is in reserve, and the two silos 10 of the storage device 1 on the right are both used to store bottom support sheets and one is in reserve.

[0092] The two silos 10 are arranged side by side along the second direction y. Along the second direction y, the two silos 10 can be arranged at intervals, or they can be arranged adjacent to each other with basically no spacing. The movable structure 22 can drive the protective structure 21 to move back and forth along the second direction y, so that the protective structure 21 can move through the feeding positions of the two silos 10, so that the protective structure 21 can move back and forth and switch between the feeding positions of the two silos 10. That is, the protective structure 21 can move to the feeding position of the silo 10 to be replenished, so as to isolate and block the physical interaction between the silo 10 to be replenished and other equipment in the battery production line; at the same time, the protective structure 21 will move away from the feeding position of another silo 10, and avoid and expose the opening 11 of the silo 10, so that the silo 10 can normally supply other equipment in the battery production line.

[0093] By adopting the above solution, two silos 10 can be provided so that while one of the silos 10 is being refilled or waiting for refilling, the other silo 10 can continue to supply materials to other equipment in the battery production line. Based on this, it is convenient to realize non-stop material supply and uninterrupted material supply, reduce production downtime due to refilling, and improve the production efficiency of the battery production line.

[0094] Furthermore, the protective structure 21 can be driven by the mobile structure 22 to switch and move between the feeding positions of the two silos 10 along the second direction y, so as to isolate other equipment of the battery production line for any silo 10 to be replenished via the protective structure 21, thereby reducing the interactivity between the replenished silo 10 and other equipment of the battery production line during the replenishment of any silo 10, reducing the probability of accidents during the replenishment of any silo 10, and improving the reliability of the storage device 1 during the replenishment of any silo 10. Furthermore, the two silos 10, one for backup and the other for use, can share one protective mechanism 20, based on which the number of protective mechanisms 20 can be reduced, the structure of the storage device 1 can be simplified, the layout and space occupancy of the storage device 1 can be compact and optimized, and the cost and energy consumption of the storage device 1 can be reduced.

[0095] Of course, in other embodiments, only one silo 10 may be provided, or at least three silos 10 may be provided.

[0096] See also Figure 1 , Figure 3 In some embodiments of the present application, the storage device 1 includes at least one detection component 30, the detection component 30 includes two detectors 31, one of the two detectors 31 is connected to the protective structure 21 and moves synchronously with the protective structure 21, and the other of the two detectors 31 is fixed to the edge of the opening 11 of the silo 10, and the two detectors 31 are aligned with each other to detect whether the protective structure 21 is in place relative to the silo 10.

[0097] It should be noted that at least one detection component 30 may be disposed between each silo 10 and the protective structure 21, so as to detect whether the protective structure 21 is in place via the detection component 30. In some embodiments, two silos 10 are provided, and one detection component 30 is disposed between each silo 10 and the protective structure 21.

[0098] The detection assembly 30 includes two detectors 31, one of which is installed on the protective structure 21 and can move synchronously with the protective structure 21, and the other detector 31 is installed on the edge of the opening 11 of the silo 10 and is fixed relative to the silo 10. When the protective structure 21 and the silo 10 are at the same feeding position, the two detectors 31 can detect each other in alignment to determine whether "the protective structure 21 has reached the feeding position of the silo 10" or "the protective structure 21 is precisely in place". On the contrary, if the two detectors 31 are not detected in alignment, it can be determined that "the protective structure 21 has not reached the feeding position of the silo 10" or "the protective structure 21 is not in place".

[0099] The “edge of the opening 11 of the silo 10 ” refers to the peripheral portion of the silo 10 that encloses the opening 11 .

[0100] The detector 31 may be installed by, but is not limited to, bonding, welding, or clamping.

[0101] The detector 31 may adopt various types of sensors, especially non-contact sensors, such as proximity sensors, photoelectric sensors, ultrasonic sensors, magnetic sensors, laser sensors, radar sensors, etc.

[0102] By adopting the above scheme, during the movement of the protective structure 21 to the feeding position of the silo 10, the two detectors 31 of the detection assembly 30 corresponding to the protective structure 21 and the silo 10 can be detected to detect whether "the protective structure 21 has reached the feeding position of the silo 10" and "the protective structure 21 is in place". Based on this, a confirmation mechanism for the position of the protective structure 21 can be formed, which can facilitate the storage device 1 and the battery production line to take corresponding actions and measures according to the confirmation of the position of the protective structure 21 (for example, the silo 10 can be normally moved to the feeding position to wait for feeding when the protective structure 21 is in place, and for example, the silo 10 can be restricted from moving and feeding when the protective structure 21 is not in place, and for example, the silo 10 can be moved to the feeding position to wait for feeding when the protective structure 21 is not in place, but the battery production line will be shut down, etc.), so as to maintain and improve the operation reliability and use reliability of the storage device 1 and the battery production line during the feeding of the silo 10.

[0103] In some embodiments, the detection data of the detection component 30 can be transmitted as a signal to the control circuit (or control system) of the battery production line, that is, the confirmation result of "whether the protective structure 21 is in place" can be sent to the control circuit of the battery production line. Based on this, according to the detection result of the detection component 30, under normal circumstances (that is, when the protective structure 21 should reach the feeding position of the silo 10 to be replenished, and the corresponding detection component 30 detects that "the protective structure 21 is in place"), the control circuit of the battery production line can normally maintain the normal operation of all equipment, so that the battery production line does not stop, and the corresponding silo 10 (that is, the silo 10 corresponding to the feeding position where the protective structure 21 is in place) can be normally moved to the replenishment position to wait for replenishment, thereby taking into account the reliability of the storage device 1 during replenishment and the production efficiency of the battery production line. On the contrary, in abnormal situations, such as when the detection component 30 fails, or when the detection component 30 detects that the "protective structure 21 is not in place", the control circuit of the battery production line can be powered off and gas cut off to stop the operation of the battery production line (i.e., shut down), and the corresponding silo 10 can be moved normally to the refilling position to wait for refilling, thereby improving the reliability of the refilling operation of the storage device 1 under abnormal circumstances and reducing the probability of accidents during the refilling of the storage device 1.

[0104] See also Figure 1 In some embodiments of the present application, a safety lock is provided at the edge of the opening 11 of the silo 10 .

[0105] It should be noted that "the edge of the opening 11 of the silo 10" refers to the peripheral portion of the silo 10 that is enclosed to form the opening 11. "A safety lock is provided at the edge of the opening 11 of the silo 10" means that the safety lock is located at the opening 11 of the silo 10 and is firmly installed on the wall of the silo 10. The installation method may be but is not limited to bolt connection, bonding, welding, etc.

[0106] The safety lock has a relative locked state and unlocked state. When the silo 10 is in the feeding position, the safety lock can be switched to the locked state. In the locked state, the safety lock can be locked with the main body of the equipment used to install the storage device 1 in the battery production line to lock the silo 10 in the feeding position. Based on this, it is convenient for the silo 10 to be stable in the feeding position and reliably feed, and it is also conducive to maintaining the reliability of the storage device 1 during the feeding of the silo 10.

[0107] When the silo 10 is to be refilled, the safety lock can be switched from a locked state to an unlocked state. In the unlocked state, the safety lock can be unlocked from the equipment body used to install the storage device 1 on the battery production line to allow the silo 10 to reciprocate along the first direction x between the feeding position and the refilling position. Based on this, the silo 10 can be easily refilled.

[0108] Among them, the type of safety lock can be flexibly set, and the safety lock can adopt but is not limited to adopting electric control lock 40 (such as electromagnetic lock, electric bolt lock, etc.), mechanical lock (such as padlock, mortise lock, etc.), electronic lock (such as password lock, fingerprint lock, etc.), etc.

[0109] By adopting the above solution, when the silo 10 is to be refilled, the safety lock can be switched to the unlocked state to allow the silo 10 to reciprocate between the feeding position and the refilling position along the first direction x, so as to facilitate the refilling and resetting of the silo 10. Conversely, when the silo 10 does not need to be refilled and is in the feeding position, the safety lock can be switched to the locked state to lock the silo 10 in the feeding position, based on which, the silo 10 can be stabilized in the feeding position and reliably fed, and the position of the silo 10 can be stabilized and the internal environment can be closed during the feeding of the silo 10, so as to facilitate the maintenance of the reliability of the storage device 1 during the feeding of the silo 10.

[0110] See also Figure 1 In some embodiments of the present application, the safety lock is an electric lock 40 , and an unlocking button 50 is provided on the outside of the silo 10 , and the unlocking button 50 is connected to the electric lock 40 by signal.

[0111] It should be noted that the electric lock 40 is an electronic lock that is driven by electricity to achieve locking and unlocking. In some embodiments, the electric lock 40 uses an electromagnetic lock, which controls locking and unlocking through electromagnetic force. Of course, in other embodiments, the electric lock 40 can use an electric bolt lock, an electric strike, etc.

[0112] An unlock button 50 is provided on the outside of the silo 10, and the unlock button 50 is connected to the electric lock 40 by signal. The unlock button 50 can be pressed by a person, and when pressed, the unlock button 50 can send an unlock signal to the electric lock 40 to drive the electric lock 40 to switch from a locked state to an unlocked state.

[0113] By adopting the above solution, when the silo 10 is to be refilled, the personnel can conveniently and quickly press the unlocking button 50 from the outside of the silo 10 to send an unlocking signal to the electric lock 40 via the unlocking button 50, and drive the electric lock 40 to switch from the locked state to the unlocked state. Based on this, the unlocking operation of the silo 10 can be made simple and quick, the time consumed for unlocking can be reduced, and it is convenient for personnel to refill the unlocked silo 10, which can improve the overall work efficiency.

[0114] Of course, in other embodiments, depending on the type of safety lock, other methods may be used to trigger unlocking.

[0115] See also Figure 1 In some embodiments of the present application, at least one of the unlock button 50 and the electric lock 40 is connected to the control loop of the battery production line.

[0116] It should be noted that, in some embodiments, the unlock button 50 signal is connected to the control circuit of the battery production line, that is, the unlock button 50 is connected to the control circuit of the battery production line, so that the unlock signal sent by the unlock button 50 when being pressed can be transmitted to the control circuit of the battery production line.

[0117] In some embodiments, the electric lock 40 signal is connected to the control circuit of the battery production line, that is, the electric lock 40 is connected to the control circuit of the battery production line, so that the status (locked status and unlocked status) of the electric lock 40 can be timely fed back to the control circuit of the battery production line.

[0118] In some embodiments, the unlock button 50 and the electric lock 40 are both connected to the control circuit of the battery production line. That is, the unlock signal sent by the unlock button 50 when it is pressed can be transmitted to the control circuit of the battery production line, and the state (locked state and unlocked state) of the electric lock 40 can also be fed back to the control circuit of the battery production line in a timely manner.

[0119] By adopting the above scheme, the "unlocking signal of the unlocking button 50" and the "signal of the electric lock 40 switching to the unlocking state" can be used as a trigger mechanism for the control circuit of the battery production line to control the battery production line to stop during the refilling of the silo 10. That is, when the control circuit of the battery production line receives the "unlocking signal of the unlocking button 50" or the "signal of the electric lock 40 switching to the unlocking state", if the control circuit finds that the storage device 1 and other equipment of the battery production line have abnormal conditions (such as the operating failure of the moving structure 22, the protection structure 21 is not in place, the material taking equipment has an operating failure, etc.), the control circuit can control the battery production line to cut off power and gas, and shut down, so as to improve the reliability of the storage device 1 in the refilling operation under abnormal conditions. On the contrary, if the control circuit finds that the storage device 1 and other equipment of the battery production line are operating normally, the control circuit normally maintains the normal operation of the battery production line (that is, does not shut down), so as to take into account the reliability of the storage device 1 during the refilling period and the production efficiency of the battery production line.

[0120] Among them, when the electric lock 40 signal is connected to the control circuit of the battery production line, if the battery production line is originally in a shutdown state, and the control circuit of the battery production line receives the signal that the "electric lock 40 switches to a locked state", the control circuit can control the battery production line to resume normal operation to maintain the production efficiency of the battery production line.

[0121] This embodiment is suitable for being combined with the embodiment of "transmitting the detection data signal of the detection component 30 to the control circuit of the battery production line", so as to utilize the "unlocking signal of the unlocking button 50" and the "signal of the electric lock 40 switching to the unlocked state" as the trigger mechanism for determining whether the control circuit of the battery production line controls the shutdown of the entire battery production line, and utilize the "detection data of the detection component 30" as one of the judgment mechanisms for determining whether the control circuit of the battery production line controls the shutdown of the entire battery production line.

[0122] See also Figure 1 In some embodiments of the present application, a locking button 60 is provided on the outer side of the silo 10 , and the locking button 60 is connected to the electric control lock 40 by signal.

[0123] It should be noted that a lock button 60 is provided on the outside of the silo 10, and the lock button 60 is connected to the electric lock 40 by signal. The lock button 60 can be pressed by a person, and when the lock button 60 is pressed, a lock signal can be sent to the electric lock 40 to drive the electric lock 40 to switch from an unlocked state to a locked state.

[0124] By adopting the above solution, when the silo 10 completes the filling and resets to the feeding position, the personnel can conveniently and quickly press the locking button 60 from the outside of the silo 10 to send a locking signal to the electric lock 40 via the locking button 60, and drive the electric lock 40 to reset and switch from the unlocked state to the locked state. Based on this, the locking operation of the silo 10 can be simple and fast, and the silo 10 can be quickly and reliably locked at the feeding position, which is conducive to maintaining the reliability of the storage device 1 during the feeding of the silo 10.

[0125] Of course, in other embodiments, the electric lock 40 can be automatically reset to the locked state when the silo 10 completes the material replenishment and resets to the feeding position. In this case, the locking button 60 can be omitted.

[0126] Of course, in other embodiments, depending on the type of safety lock, other methods may be used to trigger the lock.

[0127] See also Figure 1 , Figure 4 In some embodiments of the present application, the storage device 1 includes at least one second slide rail 70 , the second slide rail 70 is extended along the first direction x, and the silo 10 is slidably connected to the at least one second slide rail 70 .

[0128] It should be noted that each silo 10 corresponds to at least one second slide rail 70. The second slide rail 70 is extended along the first direction x, and the silo 10 is slidably connected to the corresponding second slide rail 70, which can guide and constrain the moving direction and moving stroke of the silo 10.

[0129] By adopting the above scheme, by making the silo 10 slidably connected to at least one second slide rail 70 extending along the first direction x, the silo 10 can be made into a drawer type, and the moving direction and moving stroke of the silo 10 can be conveniently guided and constrained via the second slide rail 70. Based on this, on the one hand, the silo 10 can be facilitated to slide smoothly along the second slide rail 70, the resistance and friction when the silo 10 moves can be reduced, and personnel can easily, labor-savingly and quickly move the silo 10 to the feeding position or the replenishing position, which can improve the operational flexibility and convenience. On the other hand, the second slide rail 70 can provide stable guidance and constraints for the movement of the silo 10, which can improve the stability of the silo 10 during the movement, reduce the shaking or deviation of the silo 10, and improve the reliability of the storage device 1.

[0130] Among them, Figure 1 As shown, in some embodiments, a handle 14 is provided on one side of the silo 10 along the first direction x. The handle 14 can be held and applied by a person to drive the silo 10 to reciprocate between the feeding position and the replenishing position along the first direction x.

[0131] Of course, in other embodiments, the silo 10 may be directly installed in a slot extending along the first direction x, and the second slide rail 70 may be omitted.

[0132] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 In summary, the present application provides a specific example of a material storage device 1. The material storage device 1 includes a material bin 10, a protection mechanism 20, a detection component 30, an electric lock 40, an unlocking button 50, a locking button 60, and a second slide rail 70.

[0133] There are two silos 10, which are arranged side by side along the second direction y. The two silos 10 are used to store the same raw materials, and the two silos 10 can be used in reserve. The side of the silo 10 facing away from the direction of gravity has an opening 11. The silo 10 is provided with a handle 14 on the outside along the first direction x. The silo 10 is slidably connected to at least one second slide rail 70, and the second slide rail 70 is extended along the first direction x. When a person holds the handle 14 of the silo 10 and applies force, the silo 10 can slide along the second slide rail 70 to achieve reciprocating movement between the feeding position and the refilling position along the first direction x. The silo 10 can supply materials to other equipment in the battery production line at the feeding position, and the silo 10 can be refilled by personnel at the refilling position. Among them, the second direction y is perpendicular to the first direction x.

[0134] The two silos 10 share a protective mechanism 20. The protective mechanism 20 includes a protective structure 21 and a movable structure 22. The movable structure 22 includes a driver 221 and three guide assemblies 222, and the three guide assemblies 222 are spaced apart along the first direction x. The guide assembly 222 includes a first slide rail 2221 extending along the second direction y, and a slider 2222 slidably connected to the first slide rail 2221. The protective structure 21 is installed on the slider 2222 of each guide assembly 222. The driver 221 is connected to the slider 2222 of one of the guide assemblies 222, and drives the slider 2222 to slide along the first slide rail 2221, so as to drive the protective structure 21 and other sliders 2222 to move synchronously, thereby driving the protective structure 21 to move back and forth along the second direction y between the feeding positions of the two silos 10.

[0135] The protection structure 21 includes two protection plates 211, and a protection plate 211 is provided between each two adjacent guide components 222. Two opposite sides of the protection plate 211 along the first direction x are provided with connecting plates 212, and the connecting plates 212 are vertically arranged on the side of the protection plate 211 facing the moving structure 22, and the protection plate 211 is connected to two adjacent guide components 222 through the two connecting plates 212.

[0136] The protection plate 211 is provided with isolation strips 213 on opposite sides along the second direction y. When the protection structure 21 is in the feeding position, the protection structure 21 can not only cover the opening 11 of the silo 10 in the same position in parallel through the protection plate 211, but also form reliable and effective physical isolation barriers between the two wall portions of the corresponding silo 10 along the second direction y and the protection plate 211 through the two isolation strips 213 on opposite sides of the protection plate 211.

[0137] A detection assembly 30 is arranged between each silo 10 and the protective structure 21. One of the two detectors 31 of the detection assembly 30 is mounted on the protective structure 21 and can move synchronously with the protective structure 21, and the other of the two detectors 31 of the detection assembly 30 is mounted on the edge of the opening 11 of the silo 10 and fixed relative to the silo 10. When the protective structure 21 and the silo 10 are at the same feeding position, the two detectors 31 can detect each other in alignment to judge whether "the protective structure 21 has reached the feeding position of the silo 10" or "the protective structure 21 is precisely in place". On the contrary, if the two detectors 31 are not detected in alignment, it can be judged that "the protective structure 21 has not reached the feeding position of the silo 10" or "the protective structure 21 is not in place". The signal of the detection assembly 30 is connected to the control loop of the battery production line, so that the "detection data of the detection assembly 30" can be used as one of the judgment mechanisms of whether the control loop of the battery production line controls the battery production line to stop during the refilling of the silo 10.

[0138] An electric lock 40 is provided at the edge of the opening 11 of the silo 10. The electric lock 40 has a locked state and an unlocked state. The electric lock 40 can lock the silo 10 at the feeding position in the locked state, and the electric lock 40 allows the silo 10 to move along the first direction x in the unlocked state. An unlock button 50 and a lock button 60 are provided on the outside of the silo 10. Both the unlock button 50 and the lock button 60 are connected to the electric lock 40 by signal. The unlock button 50 is used to drive the electric lock 40 to switch from the locked state to the unlocked state, and the lock button 60 is used to drive the electric lock 40 to switch from the unlocked state to the locked state.

[0139] The signal of the unlock button 50 is connected to the control circuit of the battery production line, that is, the unlock signal sent by the unlock button 50 when being pressed will be transmitted to the control circuit of the battery production line, so that the "unlock signal of the unlock button 50" can be used as a trigger mechanism for whether the control circuit of the battery production line controls the battery production line to stop during the refilling of the silo 10.

[0140] Based on the above structure, when one of the silos 10 is waiting for refilling, the moving structure 22 can drive the protective structure 21 to move along the second direction y to the feeding position of the silo 10 to be refilled, so that the protective structure 21 can physically isolate other equipment of the battery production line at the feeding position. During this period, the detection component 30 corresponding to the silo 10 and the protective structure 21 can perform relevant detection and transmit the detection data signal to the control circuit of the battery production line. In this case, the personnel can be prompted to refill the silo 10 through but not limited to the touch screen. The personnel who receive the prompt can press the unlock button 50 from the outside of the silo 10 to be refilled to drive the electric control lock 40 to switch from the locked state to the unlocked state. Then, the personnel can hold the handle 14 on the outside of the silo 10 and drag the silo 10 along the second slide rail 70 from the feeding position to the refilling position. Then, the personnel can refill the silo 10 at the refilling position. During this period, the unlock signal sent by the unlock button 50 when being pressed will be transmitted to the control circuit of the battery production line. During this period, when the control circuit of the battery production line receives the "unlock signal of the unlock button 50", if the control circuit finds an abnormal situation based on the "detection data of the detection component 30" (for example, the detection component 30 fails, or the detection component 30 detects that the "protective structure 21 is not in place", etc.), the control circuit controls the battery production line to cut off power and gas and shut down. At this time, other equipment in the battery production line will not take materials from another silo 10, thereby improving the reliability of the material storage device 1 in the refilling operation under abnormal circumstances and reducing the probability of accidents during the refilling of the material storage device 1.

[0141] On the contrary, when the control circuit of the battery production line receives the "unlock signal of the unlock button 50", if the control circuit confirms that the situation is normal according to the "detection data of the detection component 30" (that is, the detection component 30 detects that the "protective structure 21 is precisely in place"), the control circuit normally maintains the normal operation of the battery production line (that is, without stopping), and at this time, other equipment of the battery production line can normally take materials from another silo 10, that is, they can replenish and supply materials without stopping, thereby improving the production efficiency of the battery production line. In addition, during the period when personnel replenish materials in the silo 10, other equipment of the battery production line can be isolated and blocked at the feeding position through the protective structure 21, so as to isolate and block the physical interaction between the silo 10 for replenishment and other equipment of the battery production line, thereby reducing the interactivity between the silo 10 for replenishment and other equipment of the battery production line, reducing the probability of accidents during the replenishment of the storage device 1, and improving the reliability of the storage device 1 during the replenishment.

[0142] When the silo 10 has completed refilling and reset to the feeding position, the personnel can easily and quickly press the locking button 60 from the outside of the silo 10 to send a locking signal to the electric lock 40 via the locking button 60, and drive the electric lock 40 to reset and switch from the unlocked state to the locked state, thereby quickly and reliably locking the silo 10 at the feeding position, which is beneficial to maintaining the reliability of the storage device 1 during the feeding of the silo 10.
