Description

Technical Field

[0001] The present invention relates to the field of new energy battery generation equipment, and in particular to a device and method for quickly and automatically boxing a battery module. Background Art

[0002] In the battery module production process, the placement of battery modules into boxes is a critical and complex step. Traditional methods often rely on manual handling and positioning, which is not only inefficient but also poses safety risks, such as the risk of modules falling or being damaged by collisions. Furthermore, with the ever-changing size and shape of battery modules, traditional methods often struggle to adapt to diverse production needs, limiting production efficiency and product quality.

[0003] In recent years, automated battery module boxing equipment has gradually become a hot topic of industry research. However, existing automated boxing equipment still has some shortcomings. For example, due to concerns that the battery module may fall during the boxing process, causing damage or safety hazards, a relatively complex boxing method is usually adopted. This method requires pressing the battery module into the box from the bottom up to ensure its vertical stability and complete the initial press-fit positioning. Then, the box as a whole is subjected to an additional flipping operation to allow the battery module to reach the usable state for the next step of the process. This complex boxing step not only increases the difficulty and complexity of the operation, but also requires additional workstations and flipping equipment to support it, resulting in reduced production efficiency and increased costs. Therefore, how to efficiently implement the boxing operation of the battery module, ensure the stability and accuracy of the battery module, and prevent it from falling and damage, has become a technical problem that needs to be solved urgently.

[0044] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the inventive product is typically placed when in use. These terms are intended solely to facilitate the description of the present invention and simplify the description, and are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third," etc., are used solely to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0046] Furthermore, terms such as "horizontal" and "vertical" do not necessarily mean that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0047] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0048] In the first aspect of the present application, a fast and automatic box-loading device for battery modules is provided, including: a material cart 1 for transporting a lower box body or a battery module; a gripping device for gripping and placing a battery module; a positioning device, arranged below the gripping device, for positioning the material cart and the lower box body; a positioning device arranged below the gripping device; the gripping device specifically includes: an upper fixed bracket 2, providing structural support for the gripping device; a first mounting frame 3, which can be lifted and connected to the upper fixed bracket 2; a suction tray 4, which can be lifted and connected to the first mounting frame 3, for sucking the battery module; an X-direction clamping mechanism and a Y-direction clamping mechanism, which are arranged on the side of the suction tray 4 and connected to the first mounting frame 3 for clamping and positioning the battery module; two anti-falling mechanisms, symmetrically connected to the opposite sides of the first mounting frame, the anti-falling mechanism including a side bracket 5 and an anti-falling drive device, the two ends of the side bracket 5 are respectively rotatably connected to the first mounting frame 3, and can swing up and down around the side of the first mounting frame 3, and the anti-falling drive device is used to drive the side bracket 5 to be lowered or retracted.

[0049] Specifically, the trolley 1 is used to transport the lower box or battery module to a predetermined position, and the positioning device accurately positions the trolley; when the trolley transports the battery module to the predetermined position, the suction plate 4 descends, uses suction to suck up the battery module, and then rises back to its position; the X-axis clamping mechanism and the Y-axis clamping mechanism are actuated to clamp and position the battery module in the X and Y directions to ensure the stability and accuracy of the battery module after grasping; the anti-falling drive device drives the side bracket 5 to be lowered to lift both sides of the lower end face of the battery module to prevent the battery module from falling during operation; after the trolley transports the lower box to the predetermined position, the positioning device positions the trolley again and accurately positions the lower box, the first installation frame 3 descends, and the battery module is sent to the entrance of the lower box. At this time, the X-axis clamping mechanism and the Y-axis clamping mechanism are retracted, and the anti-falling mechanism is also retracted, and the suction plate 4 continues to descend relative to the first installation frame 3 to press the battery module into the lower box.

[0050] In this embodiment, the combined application of the side bracket, suction plate and clamping mechanism of the anti-fall mechanism jointly ensures the stability of the battery module during clamping and subsequent operations. Among them, the side bracket effectively prevents the battery module from falling, the suction plate stably absorbs the battery module, and the clamping mechanism ensures the precise positioning and clamping of the battery module during movement and placement. The three work together to greatly improve the stability and reliability of battery module processing.

[0051] Due to the stable cooperation of the above-mentioned suction and clamping mechanisms, as well as the reliable protection of the anti-fall mechanism, this equipment can stably press the battery module into the lower box from top to bottom, avoiding the complicated steps of pressing from bottom to top and then flipping the lower box due to concerns about the battery module falling in the existing technology, thereby simplifying the process flow.

[0052] Since the flipping step and related flipping equipment are omitted, this embodiment reduces additional workstations and equipment investment, reduces production costs, and the direct pressing method from top to bottom also improves production efficiency, making the entire boxing process smoother and more efficient.

[0053] In some embodiments, the anti-fall drive device includes a bracket guide rail 6, a bracket slider 7, a bracket drive gear 8 and a bracket drive cylinder 9; the bracket guide rail 6 is fixed to the first mounting frame 3; the bracket slider 7 is slidingly connected to the bracket guide rail 6, and its lower end surface is provided with a rack; the bracket drive gear 8 is coaxially fixedly connected to one end of the side bracket 5 and meshes with the rack; the bracket drive cylinder 9 is fixed to the first mounting frame 3, and is used to drive the bracket slider 7 to move back and forth in a straight line along the bracket guide rail 6, so that the side bracket 5 is lowered or retracted.

[0054] Specifically, when the side bracket 5 needs to be lowered to prevent the battery module from falling, the bracket drive cylinder 9 pushes the bracket slide 7 forward along the bracket guide rail 6. Due to the meshing relationship between the rack and the bracket drive gear 8, the bracket drive gear 8 rotates accordingly, thereby driving the side bracket 5 to be lowered. Conversely, when the side bracket 5 needs to be retracted, the bracket drive cylinder 9 pulls the bracket slide 7 backward, and the side bracket 5 is also retracted. Through the cooperation of the bracket guide rail 6, the bracket slide 7, the bracket drive gear 8 and the bracket drive cylinder 9, the anti-fall mechanism can operate more stably and reliably, preventing the battery module from falling during the clamping and subsequent operations, thereby enhancing the stability and safety of the equipment.

[0058] Specifically, the X-axis clamping beam 10 uses a quick-change mechanism to quickly connect or disconnect the compression beam 16 from the base beam 15. A pin 17 is secured to the compression beam 16 and engages with a locking sleeve 18 on the base beam 15, secured radially through the base beam 15 by bolts. The quick-change mechanism allows for rapid connection or disconnection of the compression beam 16 from the base beam 15, improving replacement efficiency and reducing maintenance costs. A detection assembly monitors the press-fit status of the compression beam 16. If it is not properly installed, the ball 21 on the detection plug 20 is pressed back by the limiting cam within the detection ring seat 19, triggering a switch signal. This provides intuitive feedback to the operator, enabling timely detection and resolution of any issues.
