[0049] Batteries mentioned in this field can be divided into disposable batteries and rechargeable batteries according to whether they are rechargeable. Common types of rechargeable batteries currently include: lead-acid batteries, nickel-metal hydride batteries and lithium-ion batteries. Lithium-ion batteries are currently widely used in pure electric vehicles and hybrid vehicles. The capacity of lithium-ion batteries used for this purpose is relatively low, but they have larger output and charging current, and also have a longer service life, but the cost is higher.

[0050] The battery described in the embodiments of the present invention refers to a rechargeable battery. The embodiments disclosed in the present invention will be described below mainly by taking a lithium-ion battery as an example. It should be understood that the embodiments disclosed in the present invention are applicable to any other appropriate type of rechargeable battery. The battery mentioned in the embodiments disclosed in the present invention can be directly or indirectly applied to an appropriate device to power the device.

[0051] The battery mentioned in the embodiments disclosed in the present invention refers to a single physical module including one or more battery cells to provide a predetermined voltage and capacity. The battery cell is the basic unit in the battery, that is, the battery cell, and the battery cell includes a positive electrode plate, a negative electrode plate, an electrolyte and a separator. Lithium-ion battery cells mainly rely on the movement of lithium ions between the positive electrode plate and the negative electrode plate to work. Generally, they can be divided into cylindrical battery cells, rectangular battery cells and soft-pack battery cells according to the packaging method. The batteries described below will mainly revolve around rectangular battery cells. It should be understood that the embodiments described below are also applicable to cylindrical battery cells or soft-pack battery cells in some aspects.

[0052] In the related art, during the operation of the conveyor belt, as time goes by, it is easy for the conveyor belt to sag and deform, which causes the conveyor belt to slip or even fall off between the conveyor belt and the roller, and cannot meet the production rhythm.

[0053] Therefore, in order to solve the problems in the related art, the present invention arranges a roller assembly on the conveyor belt and abuts against the support member under the conveyor belt, thereby supporting the conveyor belt to run to the lower part, reducing the probability of the conveyor belt sagging and deformation, and improving production efficiency.

[0054] This conveying device can be used for conveying battery shells, for example, conveying square shells, and can also be used for conveying cylindrical shells. Alternatively, the conveying device can also be used for conveying other objects that need to be fixed on the conveyor belt, such as boxes or electronic products.

[0055] Please refer to Figure 1 and Figure 2 In one embodiment, the conveying device 100 proposed by the present invention includes a conveyor belt 10, a roller assembly 30 and a support member 40. The conveyor belt 10 is a closed loop and can be rotatably arranged; the roller assembly 30 is arranged on the outer surface of the conveyor belt 10; the support member 40 is arranged on one side of the conveyor belt 10 in the first direction to resist the peripheral side of the roller assembly 30.

[0056] It can be understood that the conveyor belt 10 is in a closed loop and is driven by the driving assembly 70 or manually driven, and can rotate along its circumference. The shape of the conveyor belt 10 here is an elliptical ring, which is stretched by two rollers 73, and the outer surface of the conveyor belt 10 is the surface away from the rollers 73. When the conveyor belt 10 is in use, it will be divided into two parts with the rollers 73 as the boundary. The higher part in the vertical direction is the upper surface of the conveyor belt 10, and the lower part is the lower surface of the conveyor belt 10. The first direction is the vertical direction, and the support member 40 is located on one side of the conveyor belt 10 in the first direction, that is, the conveyor belt 10 is arranged below its lower surface in the vertical direction when it is in use.

[0057] The roller assembly 30 is arranged on the outer surface of the conveyor belt 10 and rotates with the conveyor belt 10. When the conveyor belt 10 drives the roller assembly 30 to move to the lower side, it can abut against the support member 40. The support member 40 provides support for the roller assembly 30, so that the roller assembly 30 abuts against the conveyor belt 10, effectively preventing the conveyor belt 10 from sagging and deforming. Here, the roller assembly 30 can rotate relative to the conveyor belt 10 when abutting against the support member 40 to reduce friction and thus improve efficiency. The form of the support member 40 is not limited, and it only needs to have a surface that abuts against the roller assembly 30. In one example, the support member 40 is in the shape of a plate; in another example, the support member 40 can also be in the shape of a frame or a block. The support member 40 can be placed directly on the ground, or it can be fixed to the ground through a fixed structure, so that it is located below the lower surface of the conveyor belt 10.

[0058] Therefore, the conveying device 100 of the present invention cooperates with the roller assembly 30 and the support member 40, so that the roller assembly 30 abuts against the lower surface of the conveyor belt 10, effectively preventing the lower surface of the conveyor belt 10 from sagging and deformation, thereby extending the service life of the conveyor belt 10, reducing the slipping and falling of the conveyor belt 10, meeting the production rhythm, and improving production efficiency.

[0059] Please combine Figure 2 and Figure 3 In one embodiment of the present invention, the roller assembly 30 includes a fixed frame 31 and a roller 33, one end of the fixed frame 31 is connected to the conveyor belt 10, and the roller 33 is rotatably connected to the other end of the fixed frame 31 away from the conveyor belt 10, and the roller 33 is located in the middle of the conveyor belt 10 in the width direction.

[0060] The fixing frame 31 is used to install the roller 33 on the conveyor belt 10. The form of the fixing frame 31 is not limited. In one example, the fixing frame 31 is a rod body, and the roller 33 can be installed at a certain distance on the surface of the conveyor belt 10 through a horizontal rod or a vertical rod; or, the fixing frame 31 is a plate structure. The roller 33 can be rotatably connected to the other end of the fixing frame 31 away from the conveyor belt 10. The rotatable connection structure here can be a shaft hole matching structure or a bearing matching structure, etc., which is not limited here. The connection method between the fixing frame 31 and the conveyor belt 10 can be a detachable connection or a fixed connection, which is not limited here. The width direction of the conveyor belt 10 is perpendicular to the extension direction of the conveyor belt 10, that is, the axial direction when the roller 73 is supported on the conveyor belt 10. The middle part of the conveyor belt 10 in the width direction, that is, the midpoint of the conveyor belt 10 in the width direction and a certain distance from the midpoint, the distance value here can be set according to the axial size of the roller 33 so that the middle part of the roller 33 in the axial direction corresponds to the middle part of the conveyor belt 10 in the width direction.

[0061] Therefore, the projection of the roller 33 on the conveyor belt 10 is located in the middle of the conveyor belt 10 in the width direction. When it is in contact with the support member 40, it can react in the middle of the conveyor belt 10, thereby providing more balanced and stable support for the conveyor belt 10 and further reducing the deviation and deformation of the conveyor belt 10.

[0062] Please refer to Figure 3 In one embodiment of the present invention, the fixing frame 31 includes a base 311 and a vertical beam 312 connected to the base 311 , the base 311 is detachably connected to the conveyor belt 10 , and the roller 33 is rotatably connected to the end side of the vertical beam 312 away from the base 311 .

[0063] The fixing frame 31 includes a base 311 and a vertical beam 312. In one example, the base 311 is plate-shaped, the vertical beam 312 is also plate-shaped, and is arranged perpendicular to the base 311. The roller 33 is rotatably connected to one side of the vertical beam 312 and is away from the end of the base 311. The base 311 of this structure can increase the connection area with the conveyor belt 10, improve the connection stability, and reduce the load of the conveyor belt 10. In another example, the base 311 can also be block-shaped or other shapes, and the vertical beam 312 can also be a rod or other shapes.

[0064] In another example, when the center of the base 311 coincides with the center of the conveyor belt 10 in the width direction, the vertical beam 312 can be set at a position slightly deviated from the center of the base 311, so that the roller 33 is located at the center position of the base 311, that is, corresponding to the middle part of the conveyor belt 10 in the width direction, providing more balanced support.

[0065] The base 311 of the fixing frame 31 can be detachably mounted on the conveyor belt 10, for example, by threaded connection, snap connection, etc., so that the roller assembly 30 can be repaired and replaced when necessary, thereby improving convenience and supporting effect.

[0066] Please combine again Figure 3 In one embodiment of the present invention, a reinforcing rib 313 is convexly provided on at least one side surface of the vertical beam 312, and one end of the reinforcing rib 313 abuts against the base 311;

[0067] And / or, the base 311 is provided with a connection hole 3111, the conveyor belt 10 is provided with a mounting hole 11, and the conveyor belt 10 and the base 311 are threadedly connected by a locking piece penetrating the connection hole 3111 and the mounting hole 11.

[0068] When the vertical beam 312 and the base 311 are both in the form of plates, in order to strengthen the connection strength of the vertical beam 312, a reinforcing rib 313 is provided on the side of the vertical beam 312. The reinforcing rib 313 may be in the form of a plate or a strip, and its cross section is roughly triangular. In order to strengthen the connection strength between the base 311 and the vertical beam 312, one side of the reinforcing rib 313 extends toward the base 311 and abuts against the base 311, thereby improving the structural stability of the fixing frame 31. In one example, the vertical beam 312, the base 311 and the reinforcing rib 313 are an integrated structure, which further improves the structural strength and the supporting effect on the roller 33. In another example, the reinforcing rib 313 may be provided on two opposite sides of the vertical beam 312 to further improve the structural stability.

[0069] The reinforcement ribs 313 are provided to improve the structural stability of the fixing frame 31 , thereby further improving the effect of supporting the conveyor belt 10 to prevent sagging.

[0070] In the case of having or not having the reinforcing rib 313, the base 311 and the conveyor belt 10 are threadedly connected, the base 311 is provided with a connecting hole 3111, the conveyor belt 10 is provided with a mounting hole 11, and a locking piece, such as a bolt and a nut, is used to penetrate the connecting hole 3111 and the mounting hole 11 to realize the threaded connection. This connection method has good structural stability and is convenient for disassembly and assembly. The number of the connecting hole 3111 and the mounting hole 11 here can be multiple and one-to-one corresponding, thereby further improving the connection stability.

[0071] In one embodiment of the present invention, the surface of the roller 33 is provided with a wear-resistant layer.

[0072] Here, the entire material of the roller 33 may be wear-resistant material, so its surface is also a wear-resistant layer. For example, the material of the roller 33 may be ceramic, alloy, polyurethane or polymer composite material, etc., which has good wear resistance and corrosion resistance, and effectively improves the performance of the roller 33. Alternatively, in another example, the material of the roller 33 is not limited, and only a wear-resistant layer is provided on the surface of the roller 33. For example, the material of the roller 33 is wood, and a wear-resistant material, such as alloy or polyurethane, is plated or wrapped on its surface to form a wear-resistant layer.

[0073] The provision of the wear-resistant layer can improve the wear resistance of the roller 33 , reduce the wear of the roller 33 , thereby improving the supporting effect, preventing the conveyor belt 10 from sagging and deforming, and extending the service life of the conveying device 100 .

[0074] Please refer to Figure 1 In one embodiment of the present invention, a plurality of roller assemblies 30 are provided, and the plurality of roller assemblies 30 are arranged on the surface of the conveyor belt 10 at intervals along the rotation direction of the conveyor belt 10 .

[0075] A plurality of roller assemblies 30 are provided, for example, three or more, and a plurality of roller assemblies 30 are spaced apart on the surface of the conveyor belt 10, thereby increasing the supporting area and supporting force of the conveyor belt 10, further improving the supporting effect, and further preventing the conveyor belt 10 from sagging and deforming. In one example, a plurality of roller assemblies 30 can be evenly and spaced apart on the surface of the conveyor belt 10, so that each position of the lower surface of the conveyor belt 10 can obtain the same supporting force, further improving the supporting effect.

[0076] In one embodiment of the present invention, the surface of the support member 40 facing the conveyor belt 10 is flat and is provided with a smooth layer.

[0077] The surface of the support member 40 facing the conveyor belt 10 is a plane, which can provide uniform support for the multi-roller assembly 30 and improve the consistency of the support effect at various positions of the conveyor belt 10. In one example, the support member 40 is in the shape of a plate, which has two parallel surfaces, and both surfaces are planes, so that the bottom surface or other structures provide stable support for the side of the support member 40 away from the conveyor belt 10 to improve the support effect of the support member 40. When the surface of the support member 40 facing the conveyor belt 10 is a plane, the plane is also provided with a smooth layer. For example, the material of the support member 40 is aluminum or ceramic, and its surface is a smooth layer. Alternatively, the material of the support member 40 is not limited, and a relatively smooth material, such as metal or ceramic, is laid on its surface, which has a small roughness, thereby forming a smooth layer. The support member 40 of this structure can reduce friction, make the conveyor belt 10 run more smoothly, and improve efficiency.

[0078] Please continue to refer to Figure 1 In one embodiment of the present invention, the conveying device 100 also includes at least two fixed seats 50, and the at least two fixed seats 50 are arranged on both sides of the conveyor belt 10 in the width direction. The support member 40 can be movably connected to the two fixed seats 50 to adjust the height of the support member 40 relative to the fixed seats 50.

[0079] The fixing seat 50 is used to provide support for the support member 40, and the support member 40 can be movably connected to the two fixing seats 50, which means that the support member 40 can change its height relative to the fixing seat 50 by moving. In one example, the fixing seat 50 can be provided with a slide groove, and the edge of the support member 40 is provided with a slider, which slides with the slide groove and can be fixed at a certain height by a locking member. In another example, the fixing seat 50 is provided with a plurality of holes spaced apart in the vertical direction, and the edge of the support member 40 is provided with a corresponding hole. The locking member is used to penetrate a hole of the fixing seat 50 and a hole of the support member 40 in sequence, so that the support member 40 is fixed at a certain height, and the height of the support member 40 can be adjusted by changing the hole of the fixing seat 50 penetrated.

[0080] By making the height of the support member 40 adjustable, the degree of support for the roller assembly 30 and the conveyor belt 10 can be adjusted. It can be adjusted according to the use time to compensate for the reduction in support height due to wear, so as to extend the service life of the conveying device 100 and meet the production rhythm.

[0081] Please refer to Figure 1 In one embodiment of the present invention, a transfer member 60 is provided in the conveyor belt 10 , and the transfer member 60 is extended along the extension direction of the conveyor belt 10 and connected to the fixing seat 50 ;

[0082] The conveying device 100 also includes a driving assembly 70, which includes a driving member 71 and two rollers 73. The driving member 71 is installed on the adapter 60 and drives one of the rollers 73. The two rollers 73 are arranged at both ends of the conveyor belt 10 to drive the conveyor belt 10 to rotate under the drive of the driving member 71.

[0083] Here, the fixed seat 50 also provides support for the driving assembly 70, and an adapter 60 is set. The adapter 60 can be in the shape of a long strip and extended along the length direction of the conveyor belt 10. At least two fixed seats 50 can be set, and they are respectively located on both sides of the width direction of the conveyor belt 10, so as to support the adapter 60. The two ends of the adapter 60 can be rotatably connected to the two rollers 73, and the driving member 71 can be connected to the adapter 60 and drive one of the rollers 73. The setting of this structure can reduce the number of fixed seats 50 and can achieve a stable support effect. In one example, three groups of fixed seats 50 can be set, and the three groups are arranged at intervals in the length direction of the conveyor belt 10, and each group includes two relative fixed seats 50 to further improve the structural stability. Each fixed seat 50 may include a bottom plate and a vertical plate, and the bottom plate is extended along the width direction of the conveyor belt 10, and is used to be placed on the ground and act as a base. The vertical plate is arranged perpendicular to the bottom plate and is used to connect with the adapter 60. The support member 40 may be disposed on the bottom plate and detachably connected to the vertical plate.

[0084] The drive assembly 70 can be conveniently fixed by the setting of the adapter 60, the volume of the conveying device 100 can be reduced, the space occupied can be saved, and a stable support effect can be provided. In other examples, the fixing seat 50 can be set at both ends of the conveyor belt 10 in the length direction, and two rollers 73 are connected respectively, so that the two rollers 73 can be rotatably set with the fixing seat 50 as support.

[0085] At present, the outer shell of the battery is usually stamped, and various defects often occur during the molding process, including surface blackening, surface stains, surface oxidation water stains, surface scratches, surface convex points, surface concave points, stretch marks, edge wrinkles, etc. Defective battery outer shells will cause various problems in the produced batteries. Therefore, the battery outer shells need to be screened, and they usually need to be inspected using a visual inspection camera during screening. During this inspection process, the battery outer shell is transported to the conveyor line by a manipulator, and the surface and interior of the battery outer shell are inspected by a visual inspection camera mounted above the conveyor line. In particular, in order to facilitate the fixing of the battery outer shell, a tray is usually set on the surface of the conveyor belt. When the tray runs to the bottom, it will aggravate the sagging deformation of the conveyor belt, thereby accelerating the dimensional change of the conveyor belt, resulting in a high failure rate.

[0086] Therefore, the conveying device 100 is used to convey the battery shell 800, and the battery shell 800 can be square, rectangular or cylindrical, etc., which is not limited here. The roller assembly 30 abuts against the lower surface of the conveyor belt 10, effectively preventing the lower surface of the conveyor belt 10 from sagging and deforming, which can extend the service life of the conveyor belt 10, reduce the slippage and fall of the conveyor belt 10, meet the production rhythm, and improve production efficiency. Please refer to Figure 1 In one embodiment of the present invention, the conveying device 100 further includes a tray assembly 20 disposed on the outer surface of the conveyor belt 10 and spaced apart from the roller assembly 30 for supporting the battery housing 800 .

[0087] The tray assembly 20 is arranged on the outer surface of the conveyor belt 10 and can rotate with the conveyor belt 10. When the tray assembly 20 moves to the upper surface of the conveyor belt 10, it is used to support the battery housing 800 so that the battery housing 800 can be tested or transported between various processes. The tray assembly 20 can be fixedly connected to the conveyor belt 10, for example, by bonding; or it can be detachably connected to the conveyor belt 10, for example, by threaded connection or snap connection. The structural form of the tray assembly 20 is not limited, for example, it can be a disc structure, a positioning block structure, or a clamping claw structure, etc., which is not limited here and can be designed as needed. The tray assembly 20 is spaced from the roller assembly 30 so that the roller assembly 30 does not interfere with the battery housing 800. It can be understood that the height of the roller assembly 30 is greater than the height of the tray assembly 20, so that when the tray assembly 20 rotates to the lower surface of the conveyor belt 10, it does not contact the support member 40, reducing the wear on the tray assembly 20.

[0088] Please combine Figure 1 and Figure 3 In one embodiment of the present invention, the tray assembly 20 includes two support portions 21 spaced apart from each other. The two support portions 21 are used to support the battery housing 800 together, and the distance between the two support portions 21 is adjustable.

[0089] The shapes of the two support parts 21 can be the same or different, and the connection method between the two support parts 21 and the battery shell can be a snap connection, plug-in connection, etc., which is not limited here. In one example, each support part 21 includes a main body and two clamping parts movably arranged on the main body. The two clamping parts can be slidably arranged so that they can be inserted into the shell to play a fixing role, and the distance between the two clamping parts can be adjusted to adapt to shells of different widths. In this way, the square shell can be fixed by the four clamping parts of the two support parts 21 abutting the four top corners, so that the fixing of the shell is convenient and quick, and the production efficiency is improved. In one example, the main body is also provided with a supporting part, so as to abut the lower end face of the shell to further improve the fixing stability. The distance between the two supporting parts 21 can be adjusted, which means that the spacing between the two supporting parts 21 in the length direction of the conveyor belt 10 is adjustable. For example, the supporting parts 21 and the conveyor belt 10 are connected in a sliding manner, and the distance between the two supporting parts 21 is adjusted by sliding the supporting parts 21; or, the supporting parts 21 and the conveyor belt 10 are detachably connected, and different spacings are achieved by different assembly positions, which is not limited here.

[0090] Here, by setting the distance between the two supporting parts 21 to be adjustable, the battery housings 800 of different lengths can be supported by changing the distance between the two, thereby further improving compatibility.

[0091] Please continue to refer to Figure 3 In one embodiment of the present invention, a plurality of fixing holes 13 are provided on the surface of the conveyor belt 10 , and the plurality of fixing holes 13 are arranged at intervals along the extension direction of the conveyor belt 10 , and each support portion 21 can be detachably connected to one of the fixing holes 13 to adjust the distance between the two support portions 21 .

[0092] The shapes of the multiple fixing holes 13 can be circular, square, or irregular, etc., depending on the connection method. In one example, the fixing hole 13 is circular, and each support portion 21 is provided with a corresponding threaded hole. The support portion 21 and the conveyor belt 10 are connected by threads. When the two support portions 21 are connected, the distance between the two support portions 21 can be determined. By removing at least one of the support portions 21 and installing a fixing hole 13 at another position, the distance between the two can be adjusted. In another example, the fixing hole 13 can be a snap hole, and the support portion 21 is correspondingly provided with a snap buckle, which is snapped into the snap hole to achieve a detachable connection between the two. In other examples, the fixing hole 13 can be arranged in two rows, that is, in the width direction of the conveyor belt 10, the number of the fixing holes 13 is two, thereby improving the connection stability with the support portion 21 and improving the fixing stability of the shell.

[0093] The support portion 21 is detachably connected to a plurality of different fixing holes 13 arranged side by side, for example, by threaded connection, plug-in connection or snap-on connection, so that the distance between the two support portions 21 can be adjusted quickly and conveniently.
