[0043] The following reference Figures 1 to 7 This application describes the battery carrier device and battery production equipment as described in the embodiments.

[0044] See Figures 1 to 7 As shown, an embodiment of this application provides a battery carrying device. This battery carrying device includes a top layer support 3, a middle layer support 2, and a bottom layer support 1 stacked from top to bottom. Preferably, there are multiple middle layer support 2s, which are stacked between the top layer support 3 and the bottom layer support 1. At least the bottom layer support 1 and each middle layer support 2 are provided with a loading cavity 7 for placing a battery 5. Whether the top layer support 3 needs to be provided with a loading cavity 7 depends on the requirements. The battery carrying device provided by this application is particularly suitable for the automated loading process of finished batteries 5, such as short-blade aluminum-cased batteries 5, during transportation and PACK loading. These batteries 5 have a cuboid shape.

[0045] Specifically, the bottom support 1 is flat, preferably with a cuboid structure. The upper surface of the bottom support 1 is the first placement surface 6, the middle support 2 is stacked on the first placement surface 6, and the lower surface of the bottom support 1 is the stacking surface. The stacking surface is relatively flat, allowing the bottom support 1 to be placed stably on the tray 4 below. Preferably, the long side of the bottom support 1 is 1180mm ± 5mm, the short side is 980mm ± 5mm, and the thickness of the bottom support 1 is 80mm ± 2mm.

[0046] The first placement surface 6 is provided with a plurality of loading cavities 7, which are distributed in two rows along a first direction. Each row includes a plurality of loading cavities 7 evenly spaced along a second direction. Each loading cavity 7 is recessed downward to form a groove for placing the battery 5. Preferably, the first direction is the width direction of the bottom support 1, and the second direction is the length direction of the bottom support 1. More preferably, the depth of the loading cavity 7 is 25%-33% of the width of the battery 5.

[0047] The loading cavity 7 extends along the length direction of the battery 5. The loading cavity 7 includes a first long sidewall 17 and a second long sidewall 18 along its width direction, a first short sidewall and a second short sidewall distributed along its length direction, and a bottom wall 19. The first short sidewall and the second short sidewall are arranged parallel to each other and spaced apart, and the first short sidewall and the second short sidewall are respectively arranged perpendicular to the bottom wall 19. The first long sidewall 17 and the second long sidewall 18 are arranged facing each other. Along the depth direction of the loading cavity 7, or in other words, along the top-to-bottom direction, the distance between the first long sidewall 17 and the second long sidewall 18 gradually decreases. The first long sidewall 17 and the second long sidewall 18 are respectively inclined relative to the bottom wall 19, and the inner wall of the loading cavity 7 forms a certain slope. Preferably, the first long sidewall 17 and the second long sidewall 18 form a slope of 1.5%-3% with the bottom wall 19. After the battery 5 is placed in the loading cavity 7, a gap is formed between the inner wall of the loading cavity 7 and the insulating sheets on both sides of the battery 5. Preferably, the gap size is 1.5-2mm, which can reduce the risk of poor edge curling of the insulating sheets on both sides of the battery 5 when placing the battery 5, and can also improve the gripping accuracy of the robot when loading the battery 5. More preferably, the length of the bottom wall 19 is 3.0mm-3.5mm longer than the length of the battery 5, and the width of the bottom wall 19 is 2.0mm-2.5mm larger than the thickness of the battery 5. This design can facilitate the picking and placing of the battery 5.

[0048] Preferably, the center distance between the inner loading cavities 7 along their long sidewalls is 50mm-70mm, so that when using a robotic arm to grip the battery 5 on the battery 5 support device, the robotic arm can grip the battery 5 from either end or from the side surface.

[0049] The first placement surface 6 is also provided with a plurality of first clearance parts 10. The first clearance parts 10 have a groove structure. Each loading cavity 7 is provided with a first clearance part 10 at both ends along its length direction. The first clearance parts 10 are connected to the loading cavity 7. After the battery 5 is placed in the loading cavity 7, the first clearance parts 10 can just accommodate the terminal post of the battery 5, so as to avoid the battery 5 being squeezed in the loading cavity 7, and ensure that the terminal post is not stressed during the transportation of the battery 5 using this battery 5 carrying device, thereby reducing the risk of damage to the battery 5.

[0050] Preferably, the width of the first clearance portion 10 is 2.5-3.5 mm larger than the diameter of the battery 5 terminal post. After the battery 5 is placed in the loading cavity 7, a gap of 1.5-2.0 mm is formed between the inner wall surface of the first clearance portion 10 and the surface of the terminal post.

[0051] The first placement surface 6 is also provided with first positioning points 8. The number of first positioning points 8 is at least three. In this embodiment, the number of first positioning points 8 is preferably three. Two of the first positioning points 8 are symmetrically arranged about the centerline extending along the second direction of the bottom support member 1, and two of the first positioning points 8 are respectively located near the edge of the first placement surface 6. The third first positioning point 8 is located near the edge of one of the short sides of the first placement surface 6. Specifically, the first positioning point 8 is a recess formed locally on the first placement surface 6. The first positioning point 8 is clearly distinguished from the color of other parts of the first placement surface 6 by coloring, facilitating the recognition and image acquisition by the CCD camera on the robotic arm, thereby achieving positioning and facilitating the robotic arm's handling of the bottom support member 1. Preferably, the first positioning point 8 is circular in shape, with a diameter of 10 mm and a depth of 5 mm.

[0052] The first placement surface 6 is also provided with positive and negative polarity markings 16. A positive polarity marking 15 (or negative polarity marking 16) is provided at one end near the loading cavity 7, and a negative polarity marking 16 (or positive polarity marking 15) is provided at the other end near the loading cavity 7. When inserting the battery 5, it can be placed according to the markings.

[0053] The bottom support component 1 is generally flat and has four apex corners. Each of the four apex corners is chamfered as a positioning angle. Among the four apex corners, the two apex corners at both ends of one of the long sides are chamfered at right angles as the first positioning angle 13. Preferably, the length of the right angle chamfer is 30-50mm. The two apex corners at both ends of the other long side are chamfered at rounded arcs as the second positioning angle 14. Preferably, the radius of the rounded arc chamfer is 30-50mm. The first positioning angle 13 and the second positioning angle 14 are used to correspond with the positioning angles of other support layers when the support layers are stacked for positioning.

[0054] Furthermore, the battery 5 carrying device also includes a tray 4, which is placed at the bottom of the bottom support 1. When transferring the battery 5 carrying device, the battery 5 carrying device can be transferred and transported by forking the tray 4. The shape of the stacking surface of the bottom support 1 is adapted to the shape of the upper surface of the tray 4. Preferably, the area of ​​the upper surface of the tray 4 is larger than the area of ​​the stacking surface. After the bottom support 1 and the tray 4 are stacked, the edge of the upper surface of the tray 4 and the edge of the bottom support 1 form a gap of at least 5-10 mm to improve the stability of the bottom support 1 and other stacked supports on the tray 4.

[0055] Preferably, the length of the long side of the tray 4 is not less than 1200±5mm, and the length of the short side of the tray 4 is not less than 1000±5mm.

[0056] Furthermore, the middle layer support 2 is flat, preferably with a cuboid structure. The upper surface of the middle layer support 2 is the second placement surface, and the lower surface is the first cover surface. The second placement surface is also provided with multiple loading cavities 7 for placing the battery 5. After the middle layer support 2 is stacked on the bottom layer support 1 or another middle layer support 2, the first cover surface is placed on the bottom layer support 1 or another middle layer support 2. The distribution of the multiple loading cavities 7 on the second placement surface is the same as that on the first placement surface 6. The second placement surface is also provided with a second clearance portion, a second positioning portion, and positive and negative electrode markings. This part can be referred to in the relevant description on the first placement surface 6 above. Identical or similar content will not be described again, and those skilled in the art will fully understand. In addition, the middle layer support 2 is also provided with a first positioning angle 13 and a second positioning angle 14.

[0057] Preferably, the long side of the middle support member 2 is 1180±5mm; the short side of the middle support layer is 980±5mm; and the thickness of the middle support layer is 110±2mm.

[0058] The first cover has multiple first cavities 11, each of which is recessed towards the second placement surface to form a groove structure. The number of first cavities 11, the number of loading cavities 7 on the bottom support 1, and the number of loading cavities 7 on the other middle support 2 are the same and correspond one-to-one. Taking the middle support 2 being stacked on the bottom support 1 as an example, the first positioning angle 13 of the middle support 2 is aligned with the first positioning angle 13 of the bottom support 1, and the second positioning angle 14 of the middle support 2 is aligned with the second positioning angle 14 of the bottom support 1, thus completing the stacking of the middle support 2 and the bottom support 1. At this time, each first cavity 11 is attached to a loading cavity 7, and each group of first cavities 11 and loading cavities 7 together define a cavity that matches the shape of the battery 5. The same applies when the middle support 2 is stacked on another middle support 2 below. Preferably, the second cover also has electrode marks at both ends near the first cavities 11.

[0059] Both ends of the first cavity 11 are provided with a first widening portion 12. Along the middle position of the first cavity 11 towards the end of the first cavity 11, the width of the first widening portion 12 gradually increases. The cross-sectional area of ​​the first widening portion 12 is trapezoidal, which increases the volume of the first cavity 11 at the end. After the battery 5 is placed between the loading cavity 7 and the first cavity 11, a distance of 5mm-8mm is formed between the inner wall surface of the first widening portion 12 and the insulating sheet at the end of the battery 5. When stacking the middle layer support layer, the inner wall surface of the first cavity 11 can avoid the insulating sheet of the battery 5, so as to avoid the situation of poor edge curling of the insulating sheet of the battery 5. Whether the middle layer support 2 is stacked manually or mechanically, it can protect the insulation of the battery 5 and reduce the risk of damage to the insulating sheet of the battery 5.

[0060] It should be noted that, as described above regarding the long and short sidewalls of the bearing cavity, the first cavity 11 is also provided with a long sidewall with a slope of 1.5%-3%. Preferably, the length of the bottom wall 19 of the first cavity 11 is 4.5-5.5 mm longer than the length of the battery 5, and the width of the bottom wall 19 of the first cavity 11 is 2.0-2.5 mm greater than the thickness of the battery 5.

[0061] Furthermore, the top support 3 is flat, preferably, the top support 3 has a cuboid structure, the length of the long side of the top support 3 is 1180±5mm, the length of the short side of the top support 3 is 980±5mm, and the thickness of the top support 3 is 80±2mm.

[0062] The lower surface of the top support 3 is a second cover, and multiple second cavities are provided on the second cover. The distribution of the multiple second cavities is the same as that of the first cavity 11 mentioned above, which can be fully understood by those skilled in the art and will not be described in detail here. In addition, the top support 3 is also provided with a first positioning angle 13 and a second positioning angle 14. After the top support 3 is stacked on the middle support 2 according to the positioning angle indication, each second cavity can be correspondingly attached to a loading cavity 7 on the second placement surface of the middle support 2 to load a battery 5.

[0063] The upper surface of the top support 3 can be configured with a certain number of loading cavities 7, positioning points, and avoidance parts for avoiding the poles, depending on the specific application scenario. When these structures are not configured, it can function as a cover and be placed on top of the first middle support 2 for loading and transferring the battery 5.

[0064] It should be noted that the second cavity is provided with a second widening portion, and the second cover is provided with an pole mark. For details, please refer to the above description of the first cavity 11 and the first cover. Similar or identical content will not be described again, and those skilled in the art will fully understand.

[0065] Preferably, the top layer support 3, the middle layer support 2, and the bottom layer support 1 are integrally molded using EPP foam, which has the characteristics of smooth surface and high structural strength.

[0066] When using the battery 5 carrying device provided in this application, firstly, place the empty bottom support 1 on the tray 4, ensuring that the bottom support 1 and the long and short sides of the tray 4 are aligned. Then, place the batteries 5 to be transported into the loading cavities 7 of the bottom support 1; place the empty middle support 2 on the bottom support 1, ensuring that the first cavity 11 is attached to each battery 5, and confirm that the first positioning angle 13 and the second positioning angle 14 of the middle support 2 are aligned with the first positioning angle 13 and the second positioning angle 14 of the bottom support 1. Next, place the batteries 5 into the loading cavities 7 of the middle support 2, and repeat the above operation to complete the stacking of multiple middle support 2. Finally, place the top support 3 on the batteries 5 on the topmost middle support 2, ensuring that the second cavity is attached to the batteries 5, and confirm that the positioning angles of the top support 3, the middle support 2, and the bottom support 1 are aligned.

[0067] As can be seen, the battery 5 carrying device provided in this application effectively increases the carrying capacity of the battery 5 by loading the finished battery 5 in a combined, layered manner. During the conveying process of the battery 5, it significantly improves the conveying efficiency. In the mechanized and automated conveying process of the battery 5, it can also optimize and reduce the workstations of unpacking the packaging boxes and manual loading, effectively improving the ability to directly load the battery 5 after packaging and transportation, reducing the corresponding handling work. It can also be used for multi-layer stacking of the battery 5 during storage to reduce the storage space required, which is beneficial for the storage of the battery 5.

[0068] The embodiments of this application also provide a battery 5 production equipment, including the battery 5 support device described in any of the above embodiments, and thus have all the beneficial technical effects of the battery 5 support device, which will not be repeated here.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
