Description

Technical Field

[0001] This utility model relates to the field of battery processing technology, and in particular to a battery module positioning device. Background Technology

[0002] With the rapid development of new energy vehicles and energy storage industries, the assembly process of power battery modules has become a key factor restricting production efficiency and product quality. In the automated assembly process of battery modules, the packing process is the core step connecting module assembly and system assembly, and its operational accuracy and efficiency directly affect the overall performance and production capacity of the battery pack.

[0003] The battery module assembly methods currently used in the industry have significant technical bottlenecks. Specifically, existing assembly equipment is limited by the single design of the gripping mechanism, which can only complete the gripping and transfer of a single battery module per work cycle. This discrete operation mode limits the effective number of boxes assembled per unit time. Especially in large-scale industrial production, the single-item operation severely restricts the production line cycle time, resulting in low equipment utilization and capacity bottlenecks.

[0004] More significantly, the positioning system of existing packing equipment suffers from structural defects. Conventional devices are equipped with only a pair of compression positioning plates arranged along a single axis, which can only achieve single-dimensional positional correction during module insertion. Because battery modules exhibit multi-degree-of-freedom pose deviations in three-dimensional space, this single-direction positioning mechanism cannot effectively constrain the combined displacement of the module in the X and Y axes, resulting in the relative positional tolerance between the module and the fixed structure inside the packing exceeding the design tolerance. Particularly in multi-module stacked assembly scenarios, accumulated positioning errors can easily lead to quality defects such as poor electrical connections and misalignment of thermal management components, and may even pose potential risks to the battery system's safety performance.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] The following is combined Figures 1-6 This invention describes a battery module positioning device.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown in the embodiment of this utility model, the battery module positioning device includes: a frame structure 1, a plurality of first drivers 24, a pair of fixing plate assemblies, a plurality of second drivers 32, a pair of first fixing plates 31, and a pressing assembly 4.

[0029] Multiple first actuators 24 are disposed on the frame structure 1. A pair of fixing plate assemblies are disposed parallel to each other below the frame structure 1, and the pair of fixing plate assemblies are used to accommodate the battery module. Each fixing plate assembly is connected to at least one first actuator 24. The first actuator 24 is used to drive the pair of fixing plate assemblies to move along a first direction to clamp two opposite sides of the battery module. A second actuator 32 is disposed on the frame structure 1 and is perpendicular to the first actuators 24. A pair of first fixing plates 31 are disposed parallel to each other and perpendicular to the fixing plate assemblies. Each first fixing plate 31 is connected to at least one second actuator 32. The second actuator 32 is used to drive the pair of first fixing plates 31 to move along a second direction to clamp the other two opposite sides of the battery module, wherein the second direction is perpendicular to the first direction. The pressing component 4 includes a third driver 41 and a suction cup 43. The third driver 41 is connected to the suction cup 43. The third driver 41 is used to drive the suction cup 43 to move longitudinally. The suction cup 43 is located inside the frame structure 1 and is opposite to the space enclosed by the fixing plate assembly and the first fixing plate 31. After being clamped around the battery module, the suction cup 43 presses down and picks up the battery module.

[0030] Specifically, the first actuator 24 and the second actuator 32 are both disposed on the frame structure 1 and are perpendicular to each other, so as to drive the fixing plate assembly and the first fixing plate 31 to move in a direction perpendicular to each other. A pair of fixing plate assemblies are located below the frame structure 1, and each fixing plate assembly is connected to at least one first actuator 24. Under the action of the first actuator 24, the pair of fixing plate assemblies can move towards or away from each other. After the pressing assembly 4 places the battery module between the pair of fixing plate assemblies, the pair of fixing plate assemblies move towards each other to clamp the two sides of the battery module.

[0031] The first fixing plate 31 is perpendicularly arranged to the fixing plate assembly. Each first fixing plate 31 is connected to at least one second driver 32. Under the action of the second driver 32, the pair of first fixing plates 31 can move towards or away from each other. In embodiments of this invention, the pair of first fixing plates 31 can be disposed between the pair of fixing plate assemblies or below the pair of fixing plate assemblies. When the first fixing plate 31 is disposed below the fixing plate assembly, the height of the fixing plate assembly is less than the height of the battery module, so that the first fixing plate 31 can clamp the portion of the battery module extending outside the fixing plate assembly. After the pair of fixing plate assemblies clamp the sides of the battery module, the pair of first fixing plates 31 move towards each other to clamp the two ends of the battery module.

[0032] The suction cup 43 is located at the center of the frame structure 1 and is opposite to the space enclosed by the fixing plate assembly and the first fixing plate 31, which is the placement space for the battery module. After the fixing plate assembly and the first fixing plate 31 clamp the battery module around its perimeter, the battery module is fixed in the first and second directions and cannot move, ensuring the accuracy of the battery module before it is placed in the box. At this time, the third driver 41 drives the suction cup 43 to move downward, the suction cup 43 presses down on the battery module and picks it up. Under the action of the external driver, the positioning device moves to the top of the PACK box and places the battery module inside the PACK box. Then, the first driver 24 slightly loosens the pair of fixing plate assemblies, and the second driver 32 slightly loosens the pair of first fixing plates 31, that is, the fixing plate assembly and the first fixing plate 31 each move outward by 1mm to release the battery module, and the battery module is placed in the box.

[0033] Optionally, in an embodiment of the present invention, the first driver 24 and the second driver 32 can be a cylinder or a linear module. When the first driver 24 and the second driver 32 are cylinders, each fixed plate assembly is connected to a first driver 24, and each first fixed plate 31 is connected to a second driver 32. When the first driver 24 and the second driver 32 are linear modules, both ends of each fixed plate assembly are connected to the first driver 24, and both ends of each first fixed plate 31 are connected to the second driver 32.

[0034] In this embodiment, the frame structure 1 can be a rectangular frame, with multiple connecting ribs arranged along the first and second directions inside the rectangular frame to improve the strength of the frame structure 1. When both the first driver 24 and the second driver 32 are cylinders, both the first driver 24 and the second driver 32 are disposed on the bottom surface of the rectangular frame, with each driver perpendicular to one side of the rectangular frame; when the first driver 24 and the second driver 32 are linear modules, a pair of linear modules driving the same fixed plate assembly or the same first fixed plate 31 are arranged in parallel, with the first driver 24 disposed on the upper layer of the rectangular frame and the second driver 32 disposed on the lower layer of the rectangular frame. The connecting plate 45 is disposed at the center of the rectangular frame, and the suction cup 43 is located below the rectangular frame.

[0035] Optionally, such as Figure 3 As shown, the frame structure 1 can also be a structure formed by stacking two rectangular frames. Specifically, the frame structure 1 includes: a first frame 11, a second frame 12, and a plurality of second connectors 13. The first frame 11 and the second frame 12 are arranged in parallel, and the plurality of second connectors 13 are disposed between the first frame 11 and the second frame 12 to connect the first frame 11 and the second frame 12 into an integral structure. In this embodiment, when the driver is a cylinder, each driver can be disposed on the bottom surface of the second frame 12; when the driver is a linear module, the first driver 24 can be disposed on the second frame 12 and the side of the frame structure 1, and the second driver 32 can be disposed on the second frame 12. The connecting plate 45 is disposed at the center of the first frame 11 and connected to the first frame 11, and the suction cup 43 is located between the first frame 11 and the second frame 12. The first fixing plate 31 and part of the fixing plate assembly are located below the second frame 12.

[0036] It is understood that the main function of the frame structure 1 is to fix the first driver 24, the second driver 32 and the connecting plate 45 so that the fixing plate assembly and the first fixing plate 31 will not interfere with each other during movement. Its structural form can be various and is not limited to the two embodiments mentioned above.

[0037] The battery module positioning device provided in this embodiment of the utility model, by setting a first driver, a pair of fixing plate assemblies, a second driver and a pair of first fixing plates, can squeeze the battery module in two dimensions, in the first and second directions, before the battery module is put into the box, and adjust the angle and position of the battery module, so as to ensure the accuracy of the battery module being put into the box and improve the packing efficiency.

[0038] In an optional embodiment of the present invention, the fixing plate assembly may be a pair of second fixing plates 21, each second fixing plate 21 being connected to at least one first driver 24, and the pair of second fixing plates 21 being used to clamp the two sides of the battery module.

[0039] In another optional embodiment of this utility model, such as Figure 2 As shown, the fixing plate assembly includes a pair of second fixing plates 21 and a pair of sliders 23. The pair of second fixing plates 21 are arranged in parallel and are used to clamp the two sides of the battery module. The second fixing plates 21 are arranged perpendicularly to the first fixing plate 31. Each second fixing plate 21 has a slider 23 on its upper surface. Each slider 23 is located within the frame structure 1, and both ends of each slider 23 are connected to a first driver 24. When the first driver 24 is activated, it can drive the slider 23 to move, thereby driving the pair of second fixing plates 21 to move, so as to clamp the two sides of the battery module and realize the position adjustment of the battery module in the first direction. In this embodiment, the first driver 24 is a linear module.

[0040] like Figure 6 As shown, the battery module positioning device also includes a plurality of first connectors 25. Each first connector 25 is connected at both ends to one end of the slider 23 and the first driver 24, respectively.

[0041] Specifically, taking the second fixing plate 21 being parallel to the long side of the frame structure 1 as an example, the first driver 24 is parallel to the short side of the frame structure 1. Optionally, one end of each slider 23 can be directly connected to a first driver 24; or, one end of each slider 23 can be connected to a first driver 24 through a first connector 25; or, each slider 23 has a third connector 231 connected to its end, and the third connector 231 is connected to the first driver 24 through the first connector 25. In this embodiment, the third connector 231 can be a strip.

[0042] It should be noted that the connection between slider 23 and first driver 24 is related to the distance and position between slider 23 and first driver 24. The connection between slider 23 and first driver 24 can be flexibly set according to the setting position of first driver 24.

[0043] like Figure 3 As shown, multiple second actuators 32 are arranged parallel to the long side of the frame structure 1, and two second actuators 32 that drive one first fixing plate 31 are located inside the frame structure 1, while the other two second actuators 32 that drive another first fixing plate 31 are located outside the frame structure 1, so as to avoid interference between the multiple first actuators 24 and the multiple second actuators 32.

[0044] In an embodiment of this utility model, the battery module positioning device further includes multiple pressure sensors disposed on the first fixing plate 31 and the second fixing plate 21. The pressure sensors are used to detect the clamping force between the pair of first fixing plates 31 and the pair of second fixing plates 21 to clamp the battery module and prevent the frame structure 1 from separating from the battery module and the position of the battery module from changing when the pressing component 4 picks up the battery module for assembly.

[0045] like Figure 2 As shown, the second fixing plate 21 has notches 211 at both ends, and the notches 211 form guide grooves, allowing the first fixing plate 31 to move along the guide grooves.

[0046] Specifically, in this embodiment, as Figure 5 As shown, the first fixing plate 31 is located below the slider 23, and the first fixing plate 31 is disposed opposite to the notch 211. When the second driver 32 drives the first fixing plate 31 to move, the first fixing plate 31 can move along the guide groove onto the second fixing plate 21. In this embodiment, the first fixing plate 31 can clamp the portion of the battery module located above the guide groove to adjust the angle and position of the battery module in a second direction.

[0047] Furthermore, to increase the contact area with the battery module, a gripper 33 is provided below each first fixing plate 31. The two grippers 33 are arranged in parallel and can move between a pair of second fixing plates 21 to clamp the battery module located below the first fixing plate 31. In this embodiment, by providing a pair of grippers 33, the contact area with the battery module is increased, ensuring the accuracy of battery module position adjustment.

[0048] like Figure 2 and Figure 5 As shown, in an embodiment of this utility model, the battery module positioning device further includes a pair of protective members 5. The pair of protective members 5 are arranged parallel to the frame structure 1 and can move in the first direction or the opposite direction. The protective members 5 are used to support the battery module when it falls, so as to avoid the battery module being injured by falling objects.

[0049] Specifically, each protective component 5 includes a pair of first body parts 51 and a pair of second body parts 52. The pair of first body parts 51 are arranged in parallel, each first body part 51 has a bent portion that overlaps with the top surface of the frame structure 1 and can move along the top surface of the frame structure 1. The two ends of the second body part 52 are respectively connected to the pair of first body parts 51, and the second body part 52 is located below the first fixing plate 31.

[0050] Specifically, a pair of first body parts 51 and second body parts 52 form a U-shaped frame structure. Each first body part 51 has a bent portion at the end not connected to the second body part 52, forming a hook 511. The hook 511 overlaps with the top surface of the frame structure 1 and can slide along the top surface of the frame structure 1. When adjusting the position of the battery module, a pair of protective members 5 are located on both sides of the battery module. When the pressing component 4 adsorbs the battery module and the frame structure 1 is raised, the pair of protective members 5 slide below the battery module to prevent it from falling. In this embodiment, the frame structure 1 is also provided with a fourth actuator for driving the protective members 5 to move. Optionally, the fourth actuator can be a cylinder or a linear actuator.

[0051] like Figure 2 As shown in the embodiment of this utility model, the battery module positioning device further includes a partition 22, which is disposed between a pair of second fixing plates 21 to divide the space between the second fixing plates 21 into a plurality of accommodating spaces, each accommodating space being used to accommodate a battery module.

[0052] Specifically, a partition 22 is provided between a pair of second fixing plates 21, allowing two battery modules to be placed between them. The pair of second fixing plates 21 can simultaneously clamp the two sides of the two battery modules, and the pair of first fixing plates 31 can simultaneously clamp the end faces of the two battery modules. This enables the position and angle of the two battery modules to be adjusted simultaneously before being placed in the box, allowing the pressing component 4 to place the two battery modules into the box at one time, thus improving the packing efficiency of the battery modules.

[0053] It is understandable that when there are two separators 22, the position and angle of the three battery modules can be adjusted simultaneously.

[0054] like Figure 4 As shown, in this embodiment of the invention, the pressing assembly 4 further includes a chassis 42, with its opposite sides connected to a third actuator 41 and a suction cup 43, respectively. The third actuator 41 drives the chassis 42 to move vertically, and the suction cup 43 is detachably connected to the chassis 42, used to pick up the battery module. In this embodiment, the number of suction cups 43 matches the number of battery modules between a pair of second fixing plates 21. Optionally, the third actuator 41 can be a cylinder.

[0055] Furthermore, in an embodiment of this utility model, the suction cup 43 is connected to the chassis 42 via a quick-release connector 44 to enable quick disassembly and replacement of the suction cup 43.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model 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 of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
