[0040] The feeding box and feeding mechanism provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in combination with the accompanying drawings.

[0041] like Figure 1 , Figure 2 and Figure 4 As shown, according to some embodiments of the present application, the loading box includes: a substrate 100, a carrier plate 200 and a plurality of limiting members 300; the carrier plate 200 is arranged on the substrate 100, and a bearing surface 201 is provided in the carrier plate 200 for carrying the stacked battery cells 110; a plurality of limiting members 300 are respectively connected to the substrate 100, and are arranged at intervals around the carrier plate 200; each limiting member 300 is provided with a guide belt 310, the guide belt 310 is rotatably connected to the limiting member 300, and the guide belt 310 can move in a direction perpendicular to the bearing surface 201; the guide belt 310 is provided with a guide surface 311 suitable for contacting the battery cell 110, and the guide surface 311 is an arc structure.

[0042] In the embodiment of the present application, a plurality of limit members 300 are arranged on the substrate 100, and the plurality of limit members 300 are arranged around the four sides of the carrier plate 200. The plurality of limit members 300 and the carrier plate 200 can enclose a storage space for storing the battery cells 110. A guide belt 310 is provided in each limit member 300. The guide belt 310 is rotatably connected to the limit member 300. The guide belt 310 is provided with a guide surface 311 with an arc structure. When the battery cell 110 is placed in the storage space or when the battery cell 110 is taken out of the storage space, the battery cell 110 contacts the guide surface 311 of the guide belt 310. The guide belt 310 can move up and down together with the battery cell 110, thereby playing a guiding and limiting role for the battery cell 110. At the same time, the surface where the guide belt 310 contacts the battery cell 110 is a curved surface structure, which can reduce the contact area between the guide belt 310 and the battery cell 110 and reduce the friction between the guide belt 310 and the battery cell 110, thereby reducing damage to the edge of the battery cell 110.

[0043] It is understandable that the loading box in the embodiment of the present application can be applied to the production and manufacturing process of photovoltaic modules. In the production and manufacturing process of photovoltaic modules, it is necessary to cache and transfer the battery cells 110. The loading box in the embodiment of the present application can be used to store and load the battery cells 110. Of course, the loading box in the embodiment of the present application can also be applied to other material storage and material retrieval operation scenarios. Those skilled in the art can flexibly set it according to actual needs, and the embodiment of the present application does not limit this.

[0044] Specifically, a carrier plate 200 is arranged on the substrate 100 of the loading box, and a plurality of stoppers 300 are arranged on the substrate 100, so that the plurality of stoppers 300 are arranged at intervals around the carrier plate 200, and a storage space can be defined by the plurality of stoppers 300 and the carrier plate 200, so that the storage space can be used to accommodate the battery cells 110 to be stored. The carrier plate 200 is provided with a carrying surface 201, and the battery cells 110 to be stored can be stacked on the carrying surface 201, and the plurality of stoppers 300 can be used to limit and regularize the sides 202 of the battery cells 110.

[0045] At the same time, a guide belt 310 is provided in each stopper 300, and the guide belt 310 is provided with a guide surface 311. When the battery cell 110 is stored in the storage space, the guide surface 311 of the guide belt 310 contacts the battery cell 110. The guide belt 310 is rotatably connected to the stopper 300, and the guide belt 310 can move in a direction perpendicular to the bearing surface 201, so that during the storage and access process of the battery cell 110, the guide belt 310 can move synchronously with the up and down movement of the battery cell 110, so that the stability of the battery cell 110 during the storage and access process can be improved.

[0046] In addition, the guide surface 311 of the guide belt 310 is set to a curved surface structure. The guide belt 310 contacts the battery cell 110 through the guide surface 311 of the curved surface structure. While ensuring the guiding and limiting effect of the guide belt 310 on the battery cell 110, the friction area between the guide belt 310 and the edge of the battery cell 110 can be reduced, thereby reducing damage to the edge of the battery cell 110 and reducing the risk of hidden cracks and breakage at the edge of the battery cell 110.

[0047] It should be noted that the guide surface 311 of the guide belt 310 refers to the end surface of the guide belt 310 that cooperates with the battery cell 110 during the access process of the battery cell 110. The guide surface 311 can be an arc surface structure such as a circular arc surface, an elliptical arc surface, or an arc surface structure of other shapes. Among them, the curvature of the arc surface structure can be flexibly set according to actual needs, and the embodiment of the present application does not limit this.

[0048] For example, Figures 5 to 7 As shown, the cross-sectional shape of the guide belt 310 can be circular, semicircular, elliptical, semi-elliptical, circular or a combination of elliptical and quadrilateral structures, etc. Of course, the cross-sectional shape of the guide belt 310 can also be other shapes. Among them, the shape and structure of the guide belt 310 except the guide surface 311 are not limited, and those skilled in the art can flexibly select according to actual needs.

[0049] In some embodiments, each stopper 300 may be provided with one or more guide strips 310 . When there are more than two guide strips 310 in each stopper 300 , the more than two guide strips 310 may be arranged in parallel and spaced apart to enhance the guiding effect on the battery cell 110 .

[0050] Alternatively, if Figures 2 to 4 As shown, there are four limiting members 300 , and the four limiting members 300 correspond to the four side edges 202 of the carrier plate 200 , respectively.

[0051] In the embodiment of the present application, four limiting members 300 are provided, and the four limiting members 300 are provided around the four sides of the carrier plate 200, and each limiting member 300 corresponds to a side edge 202 of the carrier plate 200, so as to form a limiting effect on the four sides of the battery cell 110 on the carrier plate 200. The guide belts 310 in the four limiting members 300 are respectively matched with the four edges of the battery cell 110, and while the guide belts 310 guide the battery cell 110, the stress points on the four edges of the battery cell 110 can be reduced, thereby further reducing the risk of friction damage to the edges of the battery cell 110.

[0052] It can be understood that the plurality of limit members 300 on the substrate 100 are arranged around the carrier plate 200. When placing the battery cell 110 into the loading box or taking it out from the loading box, the edge of the battery cell 110 will contact the guide belt 310 in the plurality of limit members 300. The more contact points there are, the greater the probability that the edge of the battery cell 110 will be damaged by friction.

[0053] To this end, in the embodiment of the present application, a limiting member 300 is correspondingly provided on each side 202 of the carrier plate 200 so as to minimize the friction on the edge of the battery cell 110 while ensuring the guiding and limiting effect on the battery cell 110, thereby reducing the risk of damage to the edges around the battery cell 110.

[0054] It should be noted that the corresponding setting position of the limiting member 300 on each side 202 of the carrier plate 200 can be flexibly designed according to actual needs, and the embodiment of the present application does not limit this.

[0055] Alternatively, if Figure 3 and Figure 4 As shown, the bearing surface 201 has an intersecting first direction X and a second direction Y; among the four limiting members 300, two of the limiting members 300 are arranged opposite to each other along the first direction X and staggered along the first direction X; the other two limiting members 300 are arranged opposite to each other along the second direction Y and staggered along the second direction Y.

[0056] In the embodiment of the present application, two of the four limiting members 300 are arranged on opposite sides of the carrier plate 200 along the first direction X, and the two limiting members 300 are staggered, and the other two limiting members 300 are arranged on opposite sides of the carrier plate 200 along the second direction, and the two limiting members 300 are staggered. In this way, the cooperation of the four limiting members 300 can not only play a role in limiting the position of the battery cell 110, but also reserve a certain movable space for the placement of the battery cell 110, so as to adapt to the position deviation of the battery cell 110, and avoid the problem of large friction between the limiting members 300 and the battery cell 110 due to the position deviation when the battery cell 110 is placed, or even a collision occurs, which causes serious damage to the battery cell 110.

[0057] Alternatively, if Figure 3As shown, the loading plate 200 includes a first side 202a, a second side 202b, a third side 202c and a fourth side 202d connected in sequence, and four limiting members 300 are provided as a first limiting member 300a, a second limiting member 300b, a third limiting member 300c and a fourth limiting member 300d; the first limiting member 300a is provided on a side of the first side 202a close to the second side 202b, the second limiting member 300b is provided on a side of the second side 202b close to the first side 202a, the third limiting member 300c is provided on a side of the third side 202c close to the fourth side 202d, and the fourth limiting member 300d is provided on a side of the fourth side 202d close to the third side 202c.

[0058] In the embodiment of the present application, four stoppers 300 are arranged to correspond to the four side edges 202 of the carrier plate 200, and the first stopper 300a and the second stopper 300b are located on both sides of one corner of the carrier plate 200, and correspondingly, the third stopper 300c and the fourth stopper 300d are located on both sides of another corner of the carrier plate 200. In this way, the stoppers 300 are not arranged at the other two corners of the carrier plate 200, so that a certain movable space is reserved for the placement of the battery cell 110, so as to adapt to the position deviation of the battery cell 110, and avoid the problem of large friction between the stoppers 300 and the battery cell 110 due to the position deviation when the battery cell 110 is placed, or even collision, which may cause serious damage to the battery cell 110.

[0059] It is understandable that if Figure 3 As shown, the carrier plate 200 in the embodiment of the present application has four side edges 202, and a corner is formed at the intersection of two adjacent side edges 202, and then four limiting members 300 are arranged on both sides of two opposite corners, that is, the four limiting members 300 are distributed along the diagonal line of the carrier plate 200. In this way, the four limiting members 300 can be used to form a surrounding limiting effect on the battery cell 110 on the carrier plate 200, and then, at the position where the limiting member 300 is not arranged, a certain movable space can be reserved to adapt to the position deviation of the battery cell 110, so that the battery cell 110 can be taken and placed more flexibly.

[0060] Among them, the first side 202a, the second side 202b, the third side 202c and the fourth side 202d of the loading plate 200 can be distributed in a clockwise direction or a counterclockwise direction. Those skilled in the art can flexibly arrange them according to actual needs, and the embodiments of the present application do not limit this.

[0061] Alternatively, if Figure 4As shown, the loading plate 200 includes a first side 202a, a second side 202b, a third side 202c and a fourth side 202d connected in sequence, and four limiting members 300 are provided as a first limiting member 300a, a second limiting member 300b, a third limiting member 300c and a fourth limiting member 300d; the first limiting member 300a is provided on a side of the first side 202a close to the second side 202b, the second limiting member 300b is provided on a side of the second side 202b close to the third side 202c, the third limiting member 300c is provided on a side of the third side 202c close to the fourth side 202d, and the fourth limiting member 300d is provided on a side of the fourth side 202d close to the first side 202a.

[0062] In the embodiment of the present application, four limiting members 300 are provided to correspond one to one with the four side edges 202 of the carrier plate 200, and each limiting member 300 is provided close to the same side of the corresponding side edge 202. In this way, while the four limiting members 300 are used to guide and limit the battery cell 110 on the carrier plate 200, a certain movable space is also reserved for the removal and placement of the battery cell 110 to adapt to the position deviation of the battery cell 110, thereby avoiding the problem of large friction between the limiting member 300 and the battery cell 110 due to position deviation when the battery cell 110 is removed and placed, or even collision, which may cause serious damage to the battery cell 110.

[0063] It can be understood that the carrier plate 200 in the embodiment of the present application has four side edges 202, each side edge 202 has two opposite sides, and the limiting members 300 are uniformly arranged on the same side of each side edge 202, so that the two opposite limiting members 300 are staggered with each other, thereby reserving a certain movable space for the position deviation during the process of taking and placing the battery cell 110, thereby facilitating the flexible taking and placing of the battery cell 110.

[0064] For example, Figure 4 For example, the first side of the first side edge 202a is connected to the fourth side edge 202d, and the second side is connected to the second side edge 202b; correspondingly, the first side of the second side edge 202b is connected to the first side edge 202a, and the second side is connected to the third side edge 202c, and so on. Furthermore, the four stoppers 300 can be respectively arranged on the first side of the corresponding side edge 202, or simultaneously arranged on the second side of the corresponding side edge 202.

[0065] It should be noted that the first side 202a, the second side 202b, the third side 202c and the fourth side 202d of the loading plate 200 can be distributed in a clockwise direction or a counterclockwise direction. Those skilled in the art can flexibly arrange them according to actual needs, and the embodiments of the present application do not limit this.

[0066] Alternatively, if Figure 8As shown, the loading box also includes: a first roller 320 and a second roller 330, the limiting member 300 includes a first end 301 and a second end 302 that are relatively arranged; the first end 301 is connected to the substrate 100, and the second end 302 extends in a direction away from the supporting surface 201; the first roller 320 is rotatably connected to the first end 301, the second roller 330 is rotatably connected to the second end 302, and the guide belt 310 is sleeved on the first roller 320 and the second roller 330.

[0067] In the embodiment of the present application, a first roller 320 and a second roller 330 are respectively provided at opposite ends of the limit member 300, and the first roller 320 and the second roller 330 are respectively rotatably connected to the limit member 300, and the guide belt 310 is sleeved on the first roller 320 and the second roller 330, so that the guide belt 310 can be moved in a direction perpendicular to the supporting surface 201, so that during the up and down movement of the battery cell 110, the guide belt 310 can rotate synchronously, which can not only guide the battery cell 110, but also reduce the friction between the guide belt 310 and the edge of the battery cell 110.

[0068] Alternatively, if Figure 1 As shown, the substrate 100 is provided with a mounting groove 101 at a position corresponding to the limiting member 300 , the mounting groove 101 extends from the edge of the substrate 100 toward the inside of the substrate 100 , the first end 301 is connected to the mounting groove 101 , and the position of the first end 301 is adjustable.

[0069] In the embodiment of the present application, a plurality of mounting grooves 101 are provided in the substrate 100, each limiting member 300 corresponds to a mounting groove 101, and the mounting groove 101 extends from the edge of the substrate 100 toward the inside of the substrate 100, and the first end 301 of the limiting member 300 is connected to the mounting groove 101, and then by adjusting the position of the limiting member 300 in the mounting groove 101, the size of the storage space enclosed by the plurality of limiting members 300 can be adjusted to meet the storage requirements of battery cells 110 of different sizes.

[0070] Among them, the first end 301 of the limit member 300 can be slidably connected to the groove wall of the installation groove 101, and the limit member 300 can slide along the extension direction of the installation groove 101, so that when in use, the position of the limit member 300 in the installation groove 101 can be flexibly adjusted according to the size of the battery cell 110.

[0071] In addition, a fastener can be arranged between the first end 301 of the limit member 300 and the groove wall of the installation groove 101, so that after adjusting the relative position of the limit member 300 and the installation groove 101, the fastener can be used to lock the position of the limit member 300 and the substrate 100 to avoid large displacement of the limit member 300 during the storage of the battery cell 110.

[0072] In some embodiments, a plurality of spaced apart installation grooves 101 may be provided on the same side of the substrate 100, and each installation groove 101 is adapted to the first end 301 of the limiting member 300. Thus, the installation position of the limiting member 300 on the substrate 100 may be flexibly adjusted to meet different limiting requirements.

[0073] In addition, handles may be provided on opposite sides of the substrate 100 so that the substrate 100 can be moved using the handles when in use.

[0074] Alternatively, if Figure 1 As shown, the carrier plate 200 is provided with a guide groove 203 at a position corresponding to the limiting member 300 . The guide groove 203 extends from the edge of the carrier plate 200 toward the inside of the carrier plate 200 . The limiting member 300 is embedded in the guide groove 203 .

[0075] In the embodiment of the present application, by setting the guide groove 203 at the position corresponding to the limiter 300 in the carrier plate 200, the limiter 300 is embedded in the guide groove 203, and the cooperation between the guide groove 203 and the limiter 300 can play a guiding and limiting role in the process of the carrier plate 200 moving up and down. At the same time, each guide groove 203 extends from the edge of the carrier plate 200 toward the inside of the carrier plate 200, so as to meet the position adjustment requirements of the limiter 300, and then the same carrier plate 200 can be used to meet the storage requirements of battery cells 110 of different sizes.

[0076] It can be understood that the extension direction of the guide groove 203 in the carrier plate 200 is consistent with the extension direction of the installation groove 101 on the substrate 100. Furthermore, when the position of the limit member 300 on the substrate 100 is adjusted according to the size of the battery cell 110 to be stored, the carrier plate 200 can automatically adapt to the position change of the limit member 300, thereby improving the applicability of the carrier plate 200.

[0077] Accordingly, the position and number of the guide grooves 203 in the carrier plate 200 can match the position and number of the mounting grooves 101 on the base plate 100 to meet different structural assembly requirements of the loading box and improve the applicability of the loading box.

[0078] Optionally, a loading mechanism is also provided in an embodiment of the present application, including: a driving member, a transmission member, and the loading box in the above embodiment; the transmission member is connected to the loading plate 200, and the driving member is connected to the transmission member. The driving member is used to drive the transmission member to move, and drive the loading plate 200 to move up and down through the transmission member.

[0079] In the embodiment of the present application, a plurality of limit members 300 are arranged on the substrate 100, and the plurality of limit members 300 are arranged around the four sides of the carrier plate 200. The plurality of limit members 300 and the carrier plate 200 can enclose a storage space for storing the battery cells 110. A guide belt 310 is provided in each limit member 300. The guide belt 310 is rotatably connected to the limit member 300. The guide belt 310 is provided with a guide surface 311 with an arc structure. When the battery cell 110 is placed in the storage space or when the battery cell 110 is taken out of the storage space, the battery cell 110 contacts the guide surface 311 of the guide belt 310. The guide belt 310 can move up and down together with the battery cell 110, thereby playing a guiding and limiting role for the battery cell 110. At the same time, the surface where the guide belt 310 contacts the battery cell 110 is a curved surface structure, which can reduce the contact area between the guide belt 310 and the battery cell 110 and reduce the friction between the guide belt 310 and the battery cell 110, thereby reducing damage to the edge of the battery cell 110.

[0080] Specifically, the loading mechanism is provided with a driving member, a transmission member and a loading box. One end of the transmission member is connected to the loading plate 200, and the other end is connected to the driving member. The driving member can drive the loading plate 200 to move up and down through the transmission member to drive the battery cell 110 to move up and down, thereby facilitating the loading or taking of materials from the loading box.

[0081] In a specific application, the battery cells 110 are stored on the carrier plate 200. When a loading operation is required, the driving member drives the transmission member to move, and the transmission member drives the carrier plate 200 carrying the battery cells 110 to rise to a preset height, so that the material removal device can remove the battery cells 110 from the carrier plate 200. After the loading operation is completed, the driving member drives the transmission member to move, so as to drive the carrier plate 200 carrying the battery cells 110 to descend to the initial position, waiting for the next material removal operation.

[0082] Among them, the driving part can be a motor driving mechanism, a hydraulic driving mechanism or a cylinder driving mechanism, etc. Of course, other types of driving mechanisms can also be selected, and the embodiments of the present application do not limit this.

[0083] Alternatively, if Figure 1 As shown, the feeding mechanism further includes: an air knife assembly 400, which is disposed on one side of the feeding box. The air knife assembly 400 is used to convey airflow into the upper feeding box to separate the battery cells 110 in the feeding box.

[0084] In an embodiment of the present application, a wind knife assembly 400 is provided on one side of the loading box so that the wind knife assembly 400 can be used to deliver airflow into the upper loading box, so as to separate the battery cells 110 stacked in the loading box from each other, thereby facilitating the material removal operation and preventing multiple battery cells 110 from sticking to each other when removing the material.

[0085] In some embodiments, the number of wind knife assemblies 400 can be at least two, and at least two wind knife assemblies 400 are arranged on opposite sides of the loading box along a direction parallel to the carrying surface 201, and at least two wind knife assemblies 400 are staggered along a direction perpendicular to the carrying surface 201, so that at least two wind knife assemblies 400 can be used to blow air to the battery cells 110 stacked in the loading box respectively, so that the adhered battery cells 110 can be fully separated during the material removal process.

[0086] Among them, the wind knife assembly 400 can be a structural component that can convey airflow, or it can be a structural component that can generate airflow. The airflow can be continuously conveyed into the upper material box through the wind knife assembly 400. The specific structure of the wind knife assembly 400 can be flexibly set according to actual needs, and the embodiment of the present application does not limit this.
