Description

Technical Field

[0001] This application relates to the field of battery technology, and more specifically, to a battery transfer device and a battery production system. Background Technology

[0002] In the battery production process, battery transfer equipment is needed to transfer individual battery cells so that the battery cells placed on trays can be moved between production lines.

[0003] In related technologies, battery transfer equipment is prone to jamming during operation, affecting its stability and transfer efficiency. Therefore, improving the stability and transfer efficiency of battery transfer equipment is a research direction in battery technology. Utility Model Content

[0004] This application provides a battery transfer device and a battery production system, which can improve the stability and transfer efficiency of the battery transfer device.

[0005] In a first aspect, embodiments of this application provide a battery transfer device, including a transfer tray, a conveying device, and a transfer assembly. The transfer tray is used to place individual battery cells. The conveying device is used to convey the transfer tray along a first direction. The transfer assembly is adjacent to the conveying device and includes a lifting assembly and a transfer assembly. The transfer assembly is installed on the lifting assembly and moves up and down along a second direction under the drive of the lifting assembly, and is used to transfer the transfer tray to the conveying device along a third direction. The first direction, the second direction, and the third direction intersect each other.

[0006] By adopting the above technical solution, the transfer device is designed to include a lifting component and a transfer component. During transfer, the lifting component drives the transfer component to rise to a position higher than the conveying device to receive the transfer pallet. Then, through the joint action of the transfer component and the lifting component, the transfer pallet is moved to a position where it can be received by the conveying device. After receiving the transfer pallet, the conveying device transports the transfer pallet and the battery cells on it to the next process. Compared with related technologies that require reversing the transfer pallet during the transfer process and using two sets of lifting components to lift the transfer pallet twice, this method simplifies the transfer steps, improves transfer efficiency, and reduces the wear of various components and the risk of jamming during the lifting process, thereby improving the stability of equipment operation.

[0007] In some embodiments of this application, the lifting assembly includes a first mounting member and at least one lifting mechanism. The first mounting member is mounted on the lifting mechanism, and the transfer assembly is mounted on the first mounting member. The lifting mechanism is used to drive the first mounting member and the transfer assembly thereon to move up and down along the second direction.

[0008] The above technical solution is adopted, and the lifting component is designed to include a lifting mechanism and a first mounting component. The first mounting component facilitates the installation of the transfer component, and the lifting mechanism drives the first mounting component and the transfer component to lift.

[0009] In some embodiments of this application, the lifting assembly further includes a second mounting member and at least one guide member. The lifting mechanism includes a fixing member and a telescopic member mounted on the fixing member. The first mounting member is mounted on the telescopic member, and the second mounting member is mounted on the fixing member and arranged at intervals from the first mounting member along the second direction. One end of the guide member is mounted on the first mounting member, and the other end is slidably connected to the second mounting member.

[0010] By adopting the above technical solution, the lifting component is designed to include a second mounting component and a guide component. The guide component is installed on the first mounting component and slidably connected to the second mounting component. This allows the guide component to guide the first mounting component during the lifting and lowering process of the telescopic component, thereby improving the stability of the first mounting component and the transfer component on it during the lifting and lowering process.

[0011] In some embodiments of this application, the number of guide members is multiple, and the multiple guide members are arranged at center intervals around the first mounting member in the first direction and the third direction.

[0012] By adopting the above technical solution, the number of guide components is designed to be more than two, and the multiple guide components are arranged around the center of the first mounting component, so that the guide components uniformly guide the first mounting component in the circumferential direction around the center of the first mounting component, thereby further improving the stability of the first mounting component and the transfer components on it during the lifting process.

[0013] In some embodiments of this application, a plurality of the guide members are arranged in a matrix on the first mounting member, and the center of the matrix arrangement is the center of the first mounting member in the first direction and the third direction.

[0014] By adopting the above technical solution, multiple guide components are designed to be arranged in a matrix, which can provide better support and guidance for the first mounting component.

[0015] In some embodiments of this application, the plurality of guide members include a first guide member, a second guide member, a third guide member, and a fourth guide member. The first guide member and the second guide member are symmetrically arranged about the centerline of the first mounting member along the first direction, and the third guide member is symmetrically arranged about the centerline of the first mounting member along the third direction. The fourth guide member is symmetrically arranged about the centerline of the first mounting member along the first direction, and the second guide member is symmetrically arranged about the centerline of the first mounting member along the third direction.

[0016] By adopting the above technical solution, multiple guide components are designed as a first guide component, a second guide component, a third guide component, and a fourth guide component distributed at four corners. Furthermore, the arrangement direction of any two adjacent first guide components, second guide components, third guide components, and fourth guide components is along a first direction or a third direction. This allows the first mounting component to be supported and guided for lifting and lowering in the four diagonal directions, thereby further improving the stability of the lifting and lowering of the first mounting component.

[0017] In some embodiments of this application, the second mounting member is connected to the end of the fixing member facing the first mounting member.

[0018] By adopting the above technical solution, the second mounting component is connected to the end of the fixing component facing the first mounting component, so that the second mounting component and the end of the fixing component away from the first mounting component are separated by a certain distance, thereby increasing the sliding stroke of the guide component sliding on the second mounting component.

[0019] In some embodiments of this application, the number of lifting mechanisms is multiple, with at least two lifting mechanisms respectively installed at the middle position of the first mounting member along the first direction. One of the lifting mechanisms located at the middle position of the first mounting member along the first direction is located on one side of the first mounting member along the third direction, while the other lifting mechanism is located on the other side of the first mounting member along the third direction.

[0020] By adopting the above technical solution, the number of lifting mechanisms is designed to be multiple, and two lifting mechanisms are located at the middle position of the first mounting component along the first direction, and the two lifting mechanisms are respectively located on both sides of the first mounting component along the third direction. This can provide lifting support for the middle part of the first mounting component, improve the uniformity of lifting stress, and further improve the lifting stability of the first mounting component.

[0021] In some embodiments of this application, the lifting assembly further includes a third mounting member, on which the lifting mechanism is mounted.

[0022] By adopting the above technical solution, the lifting component is designed as a third mounting component, which supports and fixes the lifting mechanism, thereby improving the stability of the lifting mechanism's operation.

[0023] In some embodiments of this application, the conveying device includes two conveying components arranged parallel to each other along the third direction, the transfer device is located between the two conveying components, and the transfer component is used to drive the transfer tray to move along the first direction, the first direction being the arrangement direction of the two conveying components.

[0024] By adopting the above technical solution, the conveying device is designed to include two conveying components arranged in parallel and spaced apart, and the transfer device is set between the two conveying components. After the transfer device receives the transfer pallet, it is only necessary to move the transfer pallet above the two conveying components and then drive the transfer pallet down to realize the conveying device receiving the transfer pallet, which facilitates the conveying device to receive the transfer pallet.

[0025] In some embodiments of this application, the transfer assembly includes a first driving member, a first transfer mechanism, a second transfer mechanism, and a transmission mechanism. The first driving member is drive-connected to the first transfer mechanism. The first transfer mechanism and the second transfer mechanism are arranged at intervals along the first direction and are drive-connected through the transmission mechanism. The first transfer mechanism and the second transfer mechanism are respectively used to drive the transfer tray to move along the third direction.

[0026] By adopting the above technical solution, the transfer component is designed to include a first driving component, a first transfer mechanism, a second transfer mechanism, and a transmission mechanism. While the first driving component drives the first transfer mechanism, the first transmission mechanism can drive the second transfer mechanism. There is no need to configure a drive structure for the second transfer mechanism, which simplifies the equipment structure and reduces the equipment production cost.

[0027] In some embodiments of this application, the first transfer mechanism includes a first conveyor belt with first pulleys at both ends along the third direction; the second transfer mechanism includes a second conveyor belt with second pulleys at both ends along the third direction; the transmission mechanism includes a transmission shaft with one end coaxially connected to one of the first pulleys and the other end coaxially connected to one of the second pulleys.

[0028] By adopting the above technical solution, the first transfer mechanism and the second transfer mechanism are designed as belt drive structures, and the motion of the first transfer mechanism is transmitted to the second transfer mechanism by the drive shaft. The structure is simple and the transmission is smooth.

[0029] In some embodiments of this application, the transfer tray is provided with a plurality of receiving slots arranged along the third direction, the receiving slots being used to receive the battery cells, and the length of the battery cells located in the receiving slots is arranged along the first direction.

[0030] By adopting the above technical solution, the transfer pallet is equipped with multiple receiving slots arranged along a third direction to accommodate battery cells. This not only improves the stability of the battery cells on the transfer pallet, but also ensures that the battery cells are arranged along a third direction, which matches the transfer logic of the transfer device. This ensures that after the transfer pallet is transferred by the transfer device, the battery cells are still arranged along a third direction, which conforms to the preset transfer direction on the conveying device.

[0031] Secondly, embodiments of this application provide a battery production system, including the battery transfer equipment described in the above technical solution. Attached Figure Description

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "including," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0048] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0049] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0050] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0051] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0052] In this application, "multiple" means two or more (including two).

[0053] The embodiments of this application will now be described in detail.

[0054] In the production process of battery devices, it is necessary to transfer individual battery cells. The transfer equipment of related technologies usually rotates the tray and lifts it twice to achieve the turning and transport of individual battery cells. Since this method requires lifting and rotating the individual battery cells twice, the transfer efficiency needs to be improved. Moreover, the equipment needs to be equipped with a rotating mechanism, a primary lifting mechanism, and a secondary lifting mechanism, which increases the overall complexity and cost of the equipment.

[0055] In addition, because the equipment in this technology requires a combination of lifting and rotation, wear can easily occur on the guide rods of the lifting mechanism and the primary lifting mechanism after rotation, leading to jamming and poor operational stability. To solve this problem, the transfer equipment in this technology needs to have a certain interval between rotation and the next action to reduce jamming, but this will further reduce the transfer efficiency.

[0056] Therefore, improving the efficiency of battery cell transfer and enhancing the stability of equipment during the transfer process is an important issue in battery production and processing.

[0057] In view of this, this application provides a technical solution that improves the battery transfer equipment from the original two-stage lifting and rotating structure to a one-stage lifting structure, thereby reducing the possibility of jamming and saving the lifting and rotating action time, thus improving the transfer efficiency.

[0058] The following is in conjunction with the appendix Figure 1-7 The battery transfer device 100 provided in the embodiments of this application will be described.

[0059] Combined with appendix Figure 1-4 As shown in the figure, this application embodiment provides a battery transfer device 100, including a transfer tray 10, a conveying device 30 and a transfer device 20. The transfer tray 10 is used to place individual battery cells (not shown in the figure); the conveying device 30 is used to convey the transfer tray 10 along a first direction X; the transfer device 20 is adjacent to the conveying device 30 and includes a lifting component 21 and a transfer component 22. The transfer component 22 is installed on the lifting component 21 and is lifted and lowered along a second direction Y under the drive of the lifting component 21, and is used to transfer the transfer tray 10 to the conveying device 30 along a third direction Z. The first direction X, the second direction Y and the third direction Z intersect each other.

[0060] The transfer tray 10 is a structure for placing battery cells. Its shape can be plate-shaped, block-shaped, or disc-shaped, as long as it can accommodate one or more battery cells and maintain the stability of the battery cells on it.

[0061] During the transfer operation, a robotic arm (not shown in the figure) or the like can be used to move the transfer tray 10 along the third direction Z in the figure toward the transfer device 20. The robotic arm or the like that can move the transfer tray 10 can be regarded as a structure independent of the battery transfer device 100 of this embodiment, or it can be regarded as part of the battery transfer device 100 of this embodiment.

[0062] The battery cell mentioned in the embodiments of this application may include an electrode assembly and an electrolyte. The electrode assembly includes a positive electrode, a negative electrode, and a separator. The battery cell mainly relies on the movement of metal ions between the positive and negative electrode to operate. The positive electrode includes a positive current collector and a positive active material layer, the positive active material layer being coated on the surface of the positive current collector; the positive current collector includes a positive electrode coating area and a positive electrode tab connected to the positive electrode coating area, the positive electrode coating area being coated with the positive active material layer, and the positive electrode tab not being coated with the positive active material layer.

[0063] Taking a lithium-ion battery cell as an example, the positive electrode current collector can be made of aluminum, and the positive electrode active material layer includes positive electrode active material, which can be lithium cobalt oxide, lithium iron phosphate, ternary lithium, or lithium manganese oxide, etc. The negative electrode includes a negative electrode current collector and a negative electrode active material layer, with the negative electrode active material layer coated on the surface of the negative electrode current collector. The negative electrode current collector includes a negative electrode coating area and a negative electrode tab connected to the negative electrode coating area. The negative electrode coating area is coated with the negative electrode active material layer, while the negative electrode tab is not coated with the negative electrode active material layer. The negative electrode current collector can be made of copper, and the negative electrode active material layer includes negative electrode active material, which can be carbon or silicon, etc.

[0064] The conveying device 30 is used to convey the transfer pallet 10 to the next process along a first direction X. In some embodiments, the first direction X may be the overall length direction of the conveying device 30, and the first direction X may be a horizontal direction. Optional structural forms of the conveying device 30 are given below.

[0065] The transfer device 20 is used to load the transfer pallet 10 onto the conveying device 30 before the conveying device 30 conveys the transfer pallet 10. The transfer device 20 is adjacent to the conveying device 30, which can be understood as the transfer device 20 being adjacent to the entire or part of the conveying device 30. For example, when the conveying device 30 includes only one conveying component 31 (this embodiment is not shown in the figure), the transfer device 20 can be located on one side of the conveying device 30 along the second direction Y in the figure. As another example, when the conveying device 30 includes two parallel and spaced conveying components 31, the transfer device 20 can be located between the two conveying components 31 and adjacent to each of the two conveying components 31.

[0066] Unlike related technologies, this embodiment designs the transfer device 20 as including a lifting component 21 and a transfer component 22. During the transfer operation, the lifting component 21 drives the transfer component 22 to lift and receive the transfer pallet 10 transported by the robotic arm or other devices. Then, the transfer component 22 drives the transfer pallet 10 to a position that can be received by the conveying device 30. During or after the transfer component 22 drives the transfer pallet 10 to move, the lifting component 21 drives the transfer component 22 to descend and transfer the transfer pallet 10 to the conveying device 30, which continues to transport the pallet 10, which is moving towards a third direction Z, to a first direction X.

[0067] Compared to related technologies that require reversing the transfer pallet 10 and using two sets of lifting components 21 to lift the transfer pallet 10 twice during the transfer process, the battery transfer device 100 in this embodiment only requires one lifting and lowering of the transfer pallet 10 during the entire transfer process. It does not require reversing the transfer pallet 10, which simplifies the transfer steps, improves the transfer efficiency, and reduces the wear of various components and the risk of jamming during the lifting process, thereby improving the stability of the equipment operation.

[0068] In some examples, the lifting assembly 21 may optionally include a first mounting member 211 and at least one lifting mechanism 212, the first mounting member 211 being mounted on the lifting mechanism 212, the transfer assembly 22 being mounted on the first mounting member 211, and the lifting mechanism 212 being used to drive the first mounting member 211 and the transfer assembly 22 thereon to move up and down along the second direction Y.

[0069] The first mounting component 211 can be a plate-shaped component or a block-shaped component. The purpose of configuring the first mounting component 211 is to provide an installation base for the transfer component 22 in this embodiment, thereby facilitating the installation of the transfer component 22.

[0070] In some embodiments, the first mounting component 211 may be mounted on the top of the lifting mechanism 212 and connected to the lifting mechanism 212 by mechanical connection methods such as bolt connection, snap-fit, plug-in or welding. This embodiment will not list them all.

[0071] The lifting mechanism 212 can be any type of lifting structure, such as a hydraulic lifting structure, an electric lifting structure, a chain lifting structure, or a screw lifting structure. It can also be a structure that uses the extension and retraction of a piston rod to drive the first mounting component 211 to lift, such as a cylinder, an electric cylinder, or a hydraulic cylinder.

[0072] The transfer component 22 can also be installed on the first mounting component 211 through the above-mentioned mechanical connection, so that the lifting mechanism 212 drives the first mounting component 211 to rise and fall at the same time, it drives the transfer component 22 to rise and fall.

[0073] In some examples, the lifting assembly 21 may optionally include a second mounting member 213 and at least one guide member 214. The lifting mechanism 212 includes a fixing member 2121 and a telescopic member 2122 mounted on the fixing member 2121. A first mounting member 211 is mounted on the telescopic member 2122. A second mounting member 213 is mounted on the fixing member 2121 and is spaced apart from the first mounting member 211 along a second direction Y. One end of the guide member 214 is mounted on the first mounting member 211, and the other end is slidably connected to the second mounting member 213.

[0074] The lifting mechanism 212 includes a fixing member 2121 and a telescopic member 2122 installed on the fixing member 2121. When the lifting mechanism 212 includes the above-mentioned cylinder, electric cylinder or hydraulic cylinder, the fixing member 2121 can be the cylinder body of the cylinder, electric cylinder or hydraulic cylinder, and the telescopic member 2122 can be the piston rod of the cylinder, electric cylinder or hydraulic cylinder.

[0075] The second mounting component 213 can be installed on the fixing component 2121 by the mechanical connection method described above. The second mounting component 213 can be a plate-shaped component or a block-shaped component. Its material can be the same as or different from the first mounting component 211 mentioned above. For example, both can be metal or plastic, etc. This embodiment will not list them one by one.

[0076] The guide member 214 can be a guide rod, and the cross-section of the guide rod can be cylindrical or other shapes. In some embodiments, the upper end of the guide member 214 can be connected to the first mounting member 211 by bolts or other connecting components, or by direct welding or snap-fit.

[0077] The lower end of the guide rod is slidably connected to the second mounting member 213 via a linear bearing or a sliding sleeve or other sliding connector 215. Accordingly, the second mounting member 213 needs to be provided with a mounting hole (not shown in the figure) for the sliding connector 215 to be inserted.

[0078] The lifting assembly 21 is designed to include a second mounting member 213 and a guide member 214. The guide member 214 is installed on the first mounting member 211 and is slidably connected to the second mounting member 213. This allows the guide member 214 to guide the first mounting member 211 during the lifting and lowering process of the telescopic member 2122, thereby improving the stability of the first mounting member 211 and the transfer assembly 22 on it during the lifting and lowering process.

[0079] Combined with appendix Figure 5-7 As shown, in some examples, optionally, there are multiple guide members 214, which are arranged at center intervals around the first mounting member 211 in the first direction X and the third direction Z.

[0080] In some embodiments, the center of the first mounting member 211 in the first direction X and the third direction Z can be the centroid of the first mounting member 211 and also the center of gravity of the first mounting member 211.

[0081] The guide member 214 is designed to be more than two, meaning that the number of guide members 214 is three or more. The reason for adopting this design is that the guide rods (equivalent to the guide members 214 of this application) in related technologies and the number of primary lifting mechanisms used to drive the first mounting member 211 to lift once are both two. The two guide rods are connected to two opposite diagonal points of the first mounting member 211, and the two primary lifting mechanisms are installed at the other two opposite diagonal points of the first mounting member 211. This structure makes it impossible for the rotation center of gravity of the first mounting member 211 to coincide with the center of the first mounting member 211 itself. After long-term repeated rotation, the guide rods and primary lifting mechanisms are prone to jamming.

[0082] Therefore, in this embodiment, the number of guide rods is designed to be more than three, and the guide rods are designed to be arranged around the center of the first mounting member 211. The increase in the number of guide rods and the arrangement of the guide rods around the center of the first mounting member 211 makes the rotation center of the first mounting member 211 closer to its own center. This allows the guide member 214 to uniformly guide the first mounting member 211 in the circumferential direction around the center of the first mounting member 211, further improving the stability of the first mounting member 211 and the transfer assembly 22 on it during the lifting process and reducing the possibility of the guide member 214 getting stuck.

[0083] In some other examples, optionally, a plurality of guide members 214 are arranged in a matrix on the first mounting member 211, and the center of the matrix arrangement is the center of the first mounting member 211 in the first direction X and the third direction Z.

[0084] Multiple guide members 214 are arranged in a matrix on the first mounting member 211, which means that multiple guide members 214 are evenly arranged in rows and columns. The multiple guide members 214 have at least multiple rows and multiple columns. Each row has multiple guide members 214 evenly spaced. Each column includes multiple guide members 214 evenly spaced. Two guide members 214 in adjacent rows are arranged opposite each other along the column direction. Two guide members 214 in adjacent columns are arranged opposite each other along the column direction.

[0085] At this time, the number of guide components 214 is as follows: Figure 5 and 7 The diagram shows at least four, but of course, there could be more. Figure 6 There may be six or more of these, which will not be listed one by one in this embodiment.

[0086] The center of the matrix arrangement is the center of the first mounting member 211 in the first direction X and the third direction Z, which means that the center of the rectangular structure enclosed by the multiple guide members 214 coincides with the center of the first mounting member 211 in the first direction X and the third direction Z.

[0087] In this structure, multiple guide members 214 can provide a more uniform guiding force around the center of the first mounting member 211, which can provide better support and guidance for the first mounting member 211 and further reduce the phenomenon of guide members 214 getting stuck.

[0088] Combined again with the appendix Figure 5 As shown, in some examples, optionally, the plurality of guide members 214 include a first guide member 2141, a second guide member 2142, a third guide member 2143, and a fourth guide member 2144. The first guide member 2141 and the second guide member 2142 are symmetrically arranged about the centerline of the first mounting member 211 along the first direction X, and are symmetrically arranged about the centerline of the first mounting member 211 along the third direction Z. The fourth guide member 2144 is symmetrically arranged about the centerline of the first mounting member 211 along the first direction X, and is symmetrically arranged about the centerline of the first mounting member 211 along the third direction Z.

[0089] Taking the first mounting component 211, which is approximately rectangular in shape, as an example, the first guide component 2141 and the third guide component 2143 can be located on one of the diagonals of the first mounting component 211, and the second guide component 2142 and the fourth guide component 2144 can be located on the other diagonal of the first mounting component 211. The first guide component 2141, the second guide component 2142, the third guide component 2143 and the fourth guide component 2144 form a matrix structure.

[0090] The first guide member 2141 and the second guide member 2142 are arranged in the first direction X, the third guide member 2143 and the fourth guide member 2144 are arranged in the first direction X, the first guide member 2141 and the third guide member 2143 are arranged in the third direction Z, and the second guide member 2142 and the fourth guide member 2144 are arranged in the third direction Z. They can support and guide the first mounting member 211 in the four diagonal directions, thereby further improving the stability of the lifting of the first mounting member 211.

[0091] Combined with appendix Figure 4 As shown, in some examples, optionally, the second mounting member 213 is connected to the end of the fixing member 2121 facing the first mounting member 211.

[0092] The fastener 2121 has one end facing the first mounting member 211 (the upper end in the figure) and one end facing away from the first mounting member 211 (the lower end in the figure).

[0093] The reason for connecting the second mounting member 213 to the end of the fixing member 2121 facing the first mounting member 211 is that, since the guide member 214 and the second mounting member 213 are slidably connected, when the telescopic member 2122 drives the first mounting member 211 to descend, the guide member 214 also descends accordingly, and the lower end of the guide member 214 needs to have a certain lifting stroke space.

[0094] Therefore, in this embodiment, the second mounting member 213 is connected to the end of the fixing member 2121 facing the first mounting member 211, so that the second mounting member 213 and the end of the fixing member 2121 away from the first mounting member 211 form a certain gap. This gap is the lifting stroke space of the lower end of the guide member 214, thereby increasing the sliding stroke of the guide member 214 sliding on the second mounting member 213.

[0095] In some examples, optionally, there are multiple lifting mechanisms 212, with at least two lifting mechanisms 212 respectively installed at the middle position of the first mounting member 211 along the first direction X. One of the lifting mechanisms 212 located at the middle position of the first mounting member 211 along the first direction X is located on one side of the first mounting member 211 along the third direction Z, while the other lifting mechanism 212 is located on the other side of the first mounting member 211 along the third direction Z.

[0096] Unlike related technologies where the lifting mechanism is designed to be located at two opposite corners of the first mounting member 211, resulting in the rotation center of gravity of the first mounting member 211 not being at its own center of gravity, this embodiment designs the two lifting mechanisms 212 to be located at the middle position of the first mounting member 211 along the first direction X.

[0097] Furthermore, the two lifting mechanisms 212 are designed to be located on both sides of the first mounting member 211 along the third direction Z, which can provide lifting support for the middle part of the first mounting member 211 and improve the uniformity of lifting stress, thereby further improving the lifting stability of the first mounting member 211.

[0098] Combined with appendix Figure 2 and attached Figure 4 As shown, in some examples, the lifting assembly 21 may optionally include a third mounting member 216, on which the lifting mechanism 212 is mounted.

[0099] The third mounting component 216 can be a plate-shaped component or a block-shaped component. The third mounting component 216 can serve as the mounting base for the lifting mechanism 212, and is used to support the lifting mechanism 212 and its first mounting component 211, second mounting component 213 and transfer component 22, etc.

[0100] When there are multiple support mechanisms, all support mechanisms are installed on the third mounting component 216 by mechanical connection methods such as bolt connection or welding. In some embodiments, the fixing component 2121 of the support mechanism can be installed on the third mounting component 216 by the above-mentioned mechanical connection method.

[0101] In this embodiment, the lifting component 21 is designed as a third mounting component 216. The third mounting component 216 is used to support and fix the lifting mechanism 212, thereby improving the stability of the lifting mechanism 212's operation.

[0102] Combined again with the appendix Figure 1 As shown, in some examples, optionally, the conveying device 30 includes two conveying components 31 arranged parallel to each other along a third direction Z, the transfer device 20 is located between the two conveying components 31, and the transfer component 22 is used to drive the transfer tray 10 to move along a first direction X, the first direction X being the arrangement direction of the two conveying components 31.

[0103] The conveying component 31 may be a belt conveying component 31, which includes a third conveyor belt 311. The length direction of the third conveyor belt 311 is set along the first direction X in the figure. The two third conveyor belts 311 are parallel to each other and are arranged at intervals along the third direction Z in the figure. The transfer component 22 is located between the two third conveyor belts 311.

[0104] Of course, the conveying component 31 can also be other conveying structures, such as a conveyor chain component, etc., which will not be discussed in detail in this embodiment.

[0105] After the lifting mechanism 212 of the transfer device 20 drives the transfer component 22 to rise and receive the transfer pallet 10, it is only necessary to use the transfer component 22 to move the transfer pallet 10 above the two conveying components 31, so that the two sides of the transfer pallet 10 along the third direction Z are respectively located directly above the two first conveyor belts, and then drive the transfer pallet 10 to fall, so that the conveying device 30 can receive the transfer pallet 10, which is convenient for the conveying device 30 to receive the transfer pallet 10.

[0106] Combined with appendix Figure 2 and attached Figure 3 As shown, in some examples, optionally, the transfer assembly 22 includes a first drive member 221, a first transfer mechanism 222, a second transfer mechanism 223, and a transmission mechanism 224. The first drive member 221 is connected to the first transfer mechanism 222 in a transmission manner. The first transfer mechanism 222 and the second transfer mechanism 223 are arranged at intervals along a first direction X and are connected in a transmission manner through the transmission mechanism 224. The first transfer mechanism 222 and the second transfer mechanism 223 are respectively used to drive the transfer tray 10 to move along a third direction Z.

[0107] The first driving element 221 may be a structure that outputs torque, a structure that converts its own linear motion into rotary motion, or a structure that directly performs linear motion. The structural form of the first driving element 221 depends on the specific structure of the first transfer mechanism 222 and the second transfer mechanism 223.

[0108] For example, when both the first transfer mechanism 222 and the second transfer mechanism 223 are belt conveying mechanisms, the first driving member 221 may include a motor, which drives the pulley of the belt conveying mechanism to rotate to realize the transmission of the transmission belt.

[0109] The transmission mechanism 224 is connected to the first transfer mechanism 222 and the second transfer mechanism 223 respectively, so as to transmit the power of the first transfer mechanism 222 to the second transfer mechanism 223. Thus, while the first drive member 221 drives the first transfer mechanism 222 to move, the first transmission mechanism 224 can drive the second transfer mechanism 223 to move, without the need to configure a drive structure for the second transfer mechanism 223, simplifying the equipment structure and reducing the equipment production cost.

[0110] In some examples, optionally, the first transfer mechanism 222 includes a first conveyor belt 2221, with first pulleys 2222 respectively provided at both ends of the first conveyor belt 2221 along the third direction Z; the second transfer mechanism 223 includes a second conveyor belt 2231 and second pulleys 2232 connected to both ends of the second conveyor belt 2231 along the third direction Z; and the transmission mechanism 224 includes a transmission shaft 2241, with one end of the opposite ends of the transmission shaft 2241 coaxially connected to one of the first pulleys 2222 and the other end coaxially connected to one of the second pulleys 2232.

[0111] The first conveyor belt 2221 forms a waist-shaped closed loop structure, and the length of the closed loop structure is set along the third direction Z in the figure. Two first pulleys 2222 are respectively connected to the two ends of the closed loop structure along the third direction Z, and are used to drive the first conveyor belt 2221 to rotate.

[0112] Similarly, the length direction of the first conveyor belt 2221 is set along the third direction Z in the figure, and the two second pulleys 2232 are respectively connected to the two ends of the first conveyor belt 2221 along the third direction Z, and are used to drive the second conveyor belt 2231 to rotate.

[0113] The first driving component 221 can be directly connected to one of the first pulleys 2222, or the first driving component 221 can be connected to the teeth on the inner side of the first conveyor belt 2221 through gears, thereby driving the first pulley 2222 to rotate.

[0114] When the transfer pallet 10 is transferred, the transfer pallet 10 located on the first conveyor belt 2221 and the second conveyor belt 2231 can move along the third direction Z in the figure, so that the transfer pallet 10 can be located above the two third conveyor belts 311 mentioned above, thereby facilitating the receiving of materials by the conveying component 31 and subsequent conveying.

[0115] The transmission mechanism 224 includes a transmission shaft 2241. One end of the transmission shaft 2241 can be connected to one of the first pulleys 2222. The connection method is not limited, as long as the first pulley 2222 can drive the transmission shaft 2241 to rotate synchronously.

[0116] The other end of the drive shaft 2241 is connected to a second pulley 2232 that is arranged opposite to the first pulley 2222 along the first direction X, so that the first pulley 2222 can transmit its own torque to the second pulley 2232.

[0117] In some embodiments, the number of drive shafts 2241 can be two, with one end of each drive shaft 2241 connected to two first pulleys 2222 and the other end of each drive shaft 2241 connected to two second pulleys 2232, thereby improving the stability and efficiency of the transmission.

[0118] In this embodiment, the first transfer mechanism 222 and the second transfer mechanism 223 are designed as belt drive structures. The motion of the first transfer mechanism 222 is transmitted to the second transfer mechanism 223 by the drive shaft 2241. The structure is simple and the transmission is smooth.

[0119] Combined again with the appendix Figure 1 As shown, in some examples, the transfer tray 10 may optionally have a plurality of receiving slots 11 arranged along a third direction Z, the receiving slots 11 being used to receive battery cells, and the length of the battery cells located in the receiving slots 11 being arranged along a first direction X.

[0120] The transfer tray 10 can be transported to the transfer device 20 of this embodiment along the third direction Z in the figure. Then, the transfer component 22 of the transfer device 20 rises to receive the transfer tray 10. Subsequently, the transfer component 22 drives the transfer tray 10 to move along the third direction Z, so that the transfer tray 10 can move above the two third conveyor belts 311. During the entire transfer process, the direction of the transfer tray 10 does not change, so that the length direction of the battery cell is always set along the first direction X, and multiple battery cells can always be arranged along the third direction Z in the figure.

[0121] The transfer tray 10 is equipped with multiple receiving slots 11 arranged along the third direction Z to accommodate battery cells. This not only improves the stability of the battery cells on the transfer tray 10, but also arranges the battery cells along the third direction Z, which matches the transfer logic of the transfer device 20. This ensures that after the transfer tray 10 is transferred by the transfer device 20, the battery cells are still arranged along the third direction Z, which conforms to the preset transfer direction on the conveying device 30.
