Description

Technical Field

[0001] This utility model belongs to the field of battery manufacturing technology, specifically relating to a battery module handling and boxing device. Background Technology

[0002] With the increasing demand for long-range batteries, battery modules are becoming larger and larger. Due to their larger dimensions and heavier weight, the manual lifting and handling of large modules during mass production is slow and requires a high level of operator skill, making them prone to bumps and knocks during transport.

[0003] Chinese patent application CN118173897A discloses a flexible automatic loading device for lithium battery modules, including a gripper fixing plate, a large module grabbing mechanism slidably mounted on the upper surface of the gripper fixing plate, and a small module grabbing mechanism slidably mounted on the lower surface of the gripper fixing plate. The large module grabbing mechanism is used to grip the two end plates of the large module when loading it into the box, and to avoid obstruction when the small module grabbing mechanism is working. The small module grabbing mechanism is used to grip the two end plates of the small module when loading it into the box, and to avoid obstruction when the large module grabbing mechanism is working. This invention enables flexible production of modules of different sizes and saves manpower. However, its clamping structure is relatively complex and cumbersome to operate. Furthermore, if a module falls during the lifting process, the lack of a safety protection structure will directly lead to damage to the module upon impact, and may even cause personal injury or death, resulting in a low safety factor. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a battery module handling and boxing device that can meet the clamping, hoisting and handling of large battery modules of different widths into boxes. It is highly safe, has a simple structure, is easy to operate, and can effectively improve the automation rate of the production line.

[0005] This utility model provides the following technical solution:

[0006] A battery module transport and boxing device includes a base plate and an end face lifting mechanism and a side bottom support mechanism disposed on the base plate.

[0007] The end face hoisting mechanism includes a hoisting drive assembly and a clamping assembly connected to the hoisting drive assembly. The hoisting drive assembly can drive the clamping assembly to move relative to the substrate to achieve end face clamping of the battery module.

[0008] The side bottom support mechanism includes a bottom support drive assembly and a side pressure bottom support assembly connected to the bottom support drive assembly. The bottom support drive assembly can drive the side pressure bottom support assembly to rotate in order to achieve side positioning and bottom support of the battery module.

[0009] In the above technical solution, when handling battery modules, the hoisting drive assembly drives the clamping assembly to move relative to the substrate to clamp the end face of the battery module, thereby meeting the clamping, hoisting, and handling of battery modules of different widths into boxes, and has a wide range of applications. At the same time, the bottom-supporting drive assembly drives the side-pressure bottom-supporting assembly to rotate to achieve side-limiting and bottom-supporting of the battery module. On the one hand, limiting the side of the battery module can increase the clamping strength and improve the stability and safety of hoisting and handling; on the other hand, supporting the bottom of the battery module can prevent the battery module from falling and being damaged when the end face and side clamping fail, and also ensures the safety of the staff, with strong safety features.

[0010] Furthermore, the hoisting drive assembly includes a servo motor mounted on the bottom surface of the base plate, a coupling connected to the output shaft of the servo motor, and a lead screw connected to the coupling. The clamping assembly is connected to a lead screw nut that is fitted onto the outside of the lead screw and cooperates with the lead screw.

[0011] In the above technical solution, when the servo motor is working, its output shaft drives the lead screw to rotate through the coupling, and then the rotational motion is converted into linear motion through the lead screw nut that cooperates with it, so as to realize the movement of the clamping component, thereby clamping the end face of battery modules of different widths. The structure is simple and has a wide range of applications.

[0012] Furthermore, the clamping assembly is located at both ends of the substrate and includes a support plate and a hook connected to the support plate, wherein the support plate is slidably connected to the substrate.

[0013] In the above technical solution, when the support plate slides relative to the substrate, the hooks can clamp the battery module from both ends, so as to realize the stable hoisting and transportation of the battery module into the box.

[0014] Furthermore, the bottom surface of the substrate is provided with an end face linear guide rail, and the support plate is connected to a first slider. The first slider is mounted on the end face linear guide rail and can slide along the end face linear guide rail.

[0015] In the above technical solution, when the support plate moves, the first slider moves along the linear guide rail on the end face, which can enhance the movement stability of the support plate.

[0016] Furthermore, the bottom-support drive assembly includes a side drive cylinder mounted on the base plate, a drive block connected to the telescopic shaft of the side drive cylinder, a rack connected to the drive block, and a gear meshing with the rack.

[0017] The gear center is connected to a bottom-support drive shaft, the two ends of which are rotatably mounted on a support frame. The support frame is connected to the bottom surface of the base plate, and the side-pressure bottom-support assembly is fixedly connected to the bottom-support drive shaft.

[0018] In the above technical solution, when the side drive cylinder is working, its telescopic shaft drives the rack to move through the drive block, which in turn drives the gear meshing with the rack to rotate, thereby realizing the rotation of the side pressure bottom support component, which performs side compression and limit on the battery module and bottom support, increasing the clamping strength of the battery module while preventing the battery module from falling accidentally.

[0019] Furthermore, the side pressure bottom support assembly includes a bottom support bracket and a side compression plate and a bottom support plate connected to the bottom support bracket. The bottom support bracket is connected to the end of the bottom support drive shaft, and the planes of the side compression plate and the bottom support plate are perpendicular to each other.

[0020] In the above technical solution, when the bottom-supporting drive assembly drives the side-pressure bottom-supporting assembly to rotate 90°, the side-pressure plate can squeeze and limit the two sides of the battery module. The bottom-supporting plate is located at the bottom of the battery module to prevent the battery module from falling due to clamping failure.

[0021] Furthermore, the support frame is connected to a guide rail frame extending along the rack direction, the guide rail frame is provided with a side linear guide rail, and the rack side is provided with a second slider that cooperates with the side linear guide rail.

[0022] In the above technical solution, when the side drive cylinder drives the rack to move, the second slider moves on the side linear guide rail, thereby improving the stability of the rack movement.

[0023] Furthermore, the side bottom-supporting mechanism also includes a limiting component, which includes an upper bottom-supporting limit and a lower bottom-supporting limit. The upper bottom-supporting limit is connected to one end of the guide rail frame through an upper limit plate, and the lower bottom-supporting limit is connected to the other end of the guide rail frame through a lower limit plate. The rack is provided with limiting blocks corresponding to the positions of the upper bottom-supporting limit and the lower bottom-supporting limit.

[0024] In the above technical solution, the movement range of the rack can be limited by the cooperation of the limiting block with the upper and lower limit of the bottom support, thereby limiting the rotation angle of the bottom support bracket.

[0025] Furthermore, it also includes a first photoelectric switch, a second photoelectric switch, and a third photoelectric switch; the first photoelectric switch is disposed on the substrate and is used to detect whether there is a battery module; the second photoelectric switch is disposed on both sides of the bottom surface of the substrate and is used to detect whether the end face hoisting mechanism is clamped in place; the third photoelectric switch is disposed on the support frame and is used to detect whether the side bottom support mechanism is limited and bottomed in place.

[0026] In the above technical solution, the setting of the first photoelectric switch, the second photoelectric switch and the third photoelectric switch helps to realize automatic handling into the box without manual inspection, saving manpower, and the hoisting and boxing accuracy is high, which can effectively improve the cycle time of the boxing process and the automation rate of the production line.

[0027] Furthermore, it also includes a rangefinder mounted on the substrate, which is used to detect whether the battery box is in place and whether the battery module is in place before it is placed into the box.

[0028] In the above technical solution, the installation of the rangefinder helps the battery modules to be smoothly loaded into the box, improving the cycle time of the loading process and the automation rate of the production line.

[0029] Compared with the prior art, the beneficial effects of this utility model are:

[0030] (1) The end face hoisting mechanism of this utility model includes a hoisting drive assembly and a clamping assembly connected to the hoisting drive assembly. The hoisting drive assembly can drive the clamping assembly to move relative to the substrate to realize the end face clamping of the battery module, thereby meeting the clamping, hoisting and transporting of large battery modules of different widths into the box, and has a wide range of applications.

[0031] (2) The side bottom-supporting mechanism of this utility model includes a bottom-supporting drive assembly and a side-pressure bottom-supporting assembly connected to the bottom-supporting drive assembly. The bottom-supporting drive assembly can drive the side-pressure bottom-supporting assembly to rotate to realize the side limit and bottom support of the battery module. On the one hand, by limiting the side of the battery module, the clamping strength is increased, and the stability and safety of hoisting and handling are improved. On the other hand, by supporting the bottom of the battery module, the battery module can be prevented from falling and being damaged when the end face and side clamping fails, and the safety of the staff is also guaranteed. The safety is strong.

[0037] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0038] It should be noted that in the description of this utility model, the terms "front", "rear", "left", "right", "up", "down", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not require that this utility model must be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0039] In the description of this invention, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0040] like Figures 1-3 As shown, this embodiment provides a battery module transport and boxing device, including a base plate 4 and a base 2, an end face lifting mechanism and a side bottom support mechanism disposed on the base plate 4.

[0041] The end face lifting mechanism includes a lifting drive assembly and a clamping assembly connected to the lifting drive assembly. The lifting drive assembly can drive the clamping assembly to move relative to the substrate 4 to achieve end face clamping of the battery module.

[0042] The hoisting drive assembly includes a servo motor 19 mounted on the bottom surface of the substrate 4, a coupling 20 connected to the output shaft of the servo motor 19, and a lead screw 6 connected to the coupling 20. The clamping assembly is connected to a lead screw nut 27 that is fitted onto and cooperates with the lead screw 6. In this embodiment, in order to achieve relative clamping of the two ends of the battery module 8, the output shaft of the servo motor 19 is connected to two oppositely arranged couplings 20, each coupling 20 being connected to a ball screw. When the servo motor 19 is working, its output shaft drives the lead screw 6 to rotate through the coupling 20, and then converts the rotational motion into linear motion through the lead screw nut 27 that cooperates with it, realizing the opposite or backward movement of the clamping assemblies at both ends of the substrate 4, thereby clamping the end faces of battery modules of different widths.

[0043] The clamping assembly is located at both ends of the substrate 4, including a support plate 21 and a hook 9 connected to the support plate 21. The support plate 21 is slidably connected to the substrate 4. Specifically, the bottom surface of the substrate 4 is provided with an end face linear guide rail 5. The support plate 21 is connected to a first slider 26. The first slider 26 is mounted on the end face linear guide rail 5 and can slide along the end face linear guide rail 5, thereby realizing the relative sliding between the support plate 21 and the substrate 4. When the support plate 21 slides relative to the substrate 4, the hook 9 can clamp from both ends of the battery module 8, realizing the stable lifting and transport of the battery module 8 into the box.

[0044] The number of end-face linear guides 5 is set according to requirements, and can be one or more. In this embodiment, there are two end-face linear guides 5, which are respectively set on both sides of the bottom surface of the substrate 4, which helps to improve the movement stability of the support plate 21. There are four hooks 9, which are symmetrically distributed at both ends of the support plate 21 to stably clamp the battery module 8.

[0045] The side-mounted bottom mechanism includes a bottom-mounted driving assembly and a side-pressing bottom-mounted assembly connected to the bottom-mounted driving assembly. The bottom-mounted driving assembly can drive the side-pressing bottom-mounted assembly to rotate to achieve side-mounted positioning and bottom-mounted positioning of the battery module. To achieve side-mounted positioning and bottom-mounted positioning of the battery module 8, at least two side-mounted bottom mechanisms are provided, respectively located on both sides of the substrate 4.

[0046] The bottom-supporting drive assembly includes a side-drive cylinder 1 mounted on the substrate 4, a drive block 25 connected to the telescopic shaft of the side-drive cylinder 1, a rack 16 connected to the drive block 25, and a gear 15 meshing with the rack 16. A bottom-supporting drive shaft 23 is centrally connected to the gear 15. Both ends of the bottom-supporting drive shaft 23 are rotatably mounted on a support frame 28, which is connected to the bottom surface of the substrate 4. The side-pressure bottom-supporting assembly is fixedly connected to the bottom-supporting drive shaft 23. When the side-drive cylinder 1 operates, its telescopic shaft drives the rack 16 to move via the drive block 25, thereby driving the gear 15 meshing with the rack 16 to rotate, thus realizing the rotation of the side-pressure bottom-supporting assembly and performing side compression and bottom-supporting on the battery module 8.

[0047] Furthermore, the support frame 28 is connected to a guide rail frame extending along the direction of the rack 16. The guide rail frame is provided with a side linear guide rail 24, and the side of the rack 16 is provided with a second slider that cooperates with the side linear guide rail 24. When the side drive cylinder 1 drives the rack 16 to move, the second slider moves on the side linear guide rail 24, thereby improving the stability of the rack 16's movement.

[0048] The side-pressure bottom-support assembly includes a bottom-support bracket 13 and a side-pressure plate 11 and a bottom-support plate 12 connected to the bottom-support bracket 13. The bottom-support bracket 13 is connected to the end of the bottom-support drive shaft 23, and the planes of the side-pressure plate 11 and the bottom-support plate 12 are perpendicular to each other. When the bottom-support drive assembly drives the side-pressure bottom-support assembly to rotate 90°, the side-pressure plate 11 can squeeze and limit the two sides of the battery module 8. The bottom-support plate 12 is located at the bottom of the battery module 8. Under normal working conditions, the bottom-support plate 12 does not contact the bottom of the battery module 8. When the battery module falls abnormally, the bottom-support plate 12 plays a supporting role to prevent the battery module from falling due to clamping failure.

[0049] The side support mechanism also includes a limiting component, which includes an upper support limit 18 and a lower support limit 14. The upper support limit 18 is connected to one end of the guide rail frame via an upper limit plate, and the lower support limit 14 is connected to the other end of the guide rail frame via a lower limit plate. The rack 16 is provided with limiting blocks 17 corresponding to the positions of the upper support limit 18 and the lower support limit 14. Through the cooperation of the limiting blocks 17 with the upper support limit 18 and the lower support limit 14, the movement range of the rack 16 can be limited, thereby limiting the rotation angle of the support bracket 13. In this embodiment, the rotation angle of the support bracket 13 is 0°~90°.

[0050] The battery module handling and boxing device provided in this embodiment also includes a first photoelectric switch 3, a second photoelectric switch 7, and a third photoelectric switch 22. The first photoelectric switch 3 is disposed on the substrate 4 and is used to detect the presence or absence of a battery module. The second photoelectric switch 7 is disposed on both sides of the bottom surface of the substrate 4 and is used to detect whether the end face lifting mechanism is in place. To accommodate the handling and boxing of battery modules of different sizes, multiple sets of second photoelectric switches 7 can be arranged along the direction of the end face linear guide rail 5; alternatively, a photoelectric switch track parallel to the end face linear guide rail 5 can be arranged on the bottom surface of the substrate 4, and the second photoelectric switches 7 can be slidably disposed on the photoelectric switch track to achieve lifting detection of battery modules of different sizes. The third photoelectric switch 22 is disposed on the support frame 28 and is used to detect whether the side bottom-holding mechanism is limited and in place. The arrangement of the first photoelectric switch 3, the second photoelectric switch 7, and the third photoelectric switch 22 helps to achieve automatic handling and boxing without manual inspection, saving manpower, and providing high lifting and boxing accuracy, which can effectively improve the cycle time of the boxing process and the automation rate of the production line.

[0051] The battery module handling and boxing device provided in this embodiment also includes a rangefinder 10 disposed on the substrate 4. The rangefinder 10 is used to detect whether the box is in place and whether the battery module is in place before the battery module is placed in the box, which helps the battery module to be placed in the box smoothly, improves the cycle time of the boxing process and the automation rate of the production line.

[0052] The working principle of the battery module handling and boxing device provided in this embodiment is as follows:

[0053] The completed large battery modules are horizontally lifted and positioned on a pallet. The robot moves the battery modules into the box device and moves them to the transport position. At this time, the first photoelectric switch 3 detects the signal of the battery module. Then, the servo motor 19 drives the lead screw 6 to adjust the position of the hook 9 according to the length information of the battery module. After reaching the designated transport position of the module length, the signal of the second photoelectric switch 7 changes, confirming that the hook 9 has reached the hoisting and transport position and is clamped in place. Subsequently, the side drive cylinders 7 on both sides of the substrate 4 drive the rack 16 to move, and then through the gear 15, the side pressure bottom assembly reaches the lower limit state, that is, the side extrusion plate 11 presses down on the side of the battery module 8, and the bottom plate 12 is at the bottom of the battery module 8. In addition to the mechanical limit, the side bottom mechanism is also equipped with a third photoelectric switch 22 in the two extreme states to ensure that the side bottom mechanism is limited and the bottom is in place. After completing the bottom protection, the robot, carrying the battery module transporter, moves to the battery module loading station. The rangefinder 10 checks if the loading box is in place. If it is, the side drive cylinder 1 opens the side-pressure bottom protection assembly. After the third photoelectric switch 22 confirms the opening is complete, the battery module transporter slowly places the battery module into the designated position within the loading box. Once the rangefinder 10 detects that the battery module is in place, the servo motor 19 drives the lead screw 6 to move the hook 9 back to its original position. Finally, the battery module transporter returns to its waiting position to begin preparations for the next battery module's loading.

[0054] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
