Description

Technical Field

[0001] The utility model relates to the field of new energy battery production equipment, and particularly relates to a rapid automatic box - loading device for battery modules. Background Art

[0002] In the production process of battery modules, the box - loading operation of battery modules is a crucial and complex link. Traditional methods of loading battery modules into boxes often rely on manual handling and positioning, which not only have low efficiency but also pose safety hazards, such as the battery modules being prone to falling and colliding, resulting in damage. In addition, with the continuous changes in the size and shape of battery modules, traditional methods are often difficult to adapt to diverse production requirements, restricting production efficiency and product quality.

[0003] In recent years, automated battery module box - loading devices have gradually become a hot topic in industry research. However, existing automated box - loading devices still have some deficiencies. For example, due to concerns about the battery modules falling during the box - loading process, resulting in damage or safety hazards, a relatively complex box - loading method is usually adopted. This method requires pressing the battery module into the box from bottom to top to ensure its stability in the vertical direction and complete the preliminary pressing and positioning. Then, an additional flipping operation is performed on the entire box to enable the battery module to reach the usage state for the next process; such complex box - loading steps not only increase the difficulty and complexity of the operation but also require additional workstations and flipping devices to support, thus leading to a reduction in production efficiency and an increase in costs. Therefore, how to efficiently implement the box - loading operation of battery modules and ensure the stability and accuracy of battery modules, preventing them from falling and being damaged, has become a technical problem to be urgently solved.

Detailed implementation manners

[0044] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0045] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the present utility model is customarily placed during use. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", "third", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0046] In addition, the terms "horizontal", "vertical", etc. do not mean that the components are required to be absolutely horizontal or hanging vertically, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0047] In the description of the present utility model, it should also be noted that unless otherwise clearly specified and defined, the terms "set", "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0048] In the first aspect of the present application, a rapid automatic box - loading device for a battery module is provided, including: a material cart 1 for transporting a lower box body or a battery module; a gripper device for grasping and placing the battery module; a positioning device disposed below the gripper device for positioning the material cart and the lower box body; the positioning device disposed below the gripper device; the gripper device specifically includes: an upper fixed bracket 2 providing structural support for the gripper device; a first mounting frame 3 connected to the upper fixed bracket 2 in a liftable manner; a suction cup 4 connected to the first mounting frame 3 in a liftable manner for sucking the battery module; an X - direction clamping mechanism and a Y - direction clamping mechanism disposed on the periphery of the suction cup 4 and connected to the first mounting frame 3 for clamping and positioning the battery module; two anti - fall mechanisms symmetrically connected to the opposite sides of the first mounting frame. The anti - fall assembly includes a side bracket 5 and an anti - fall driving 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. The anti - fall driving device is used to drive the side bracket 5 to lower or retract.

[0049] Specifically, the skip 1 is used to transport the lower box body or the battery module to a predetermined position, and the positioning device accurately positions the skip; after the skip transports the battery module to the predetermined position, the suction cup 4 descends, sucks up the battery module by using suction force, and then ascends and returns to the original position; the X-direction clamping mechanism and the Y-direction clamping mechanism act to clamp and position the battery module in the X and Y directions to ensure the stability and accuracy of the battery module after being grasped; the anti-falling driving device drives the side bracket 5 to lower, and supports both sides of the lower end face of the battery module to prevent the battery module from falling during operation; after the skip transports the lower box body to the predetermined position, the positioning device positions the skip again and accurately positions the lower box body, and the first mounting frame 3 descends to send the battery module to the entrance of the lower box body. At this time, the X-direction clamping mechanism and the Y-direction clamping mechanism retract, and the anti-falling mechanism also retracts. The suction cup 4 continues to descend relative to the first mounting frame 3 to press the battery module into the lower box body.

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

[0051] Due to the stable cooperation of the above-mentioned suction and clamping mechanisms and the reliable protection of the anti-falling mechanism, this equipment can stably press the battery module into the lower box body from top to bottom, avoiding the complex steps of pressing from bottom to top and then flipping the lower box body due to the worry of the battery module falling in the prior art, thus simplifying the process flow.

[0052] Since the flipping step and the related flipping equipment are omitted, this embodiment reduces the additional workstations and equipment investment, reduces the production cost, and moreover, the method of directly pressing from top to bottom also improves the production efficiency, making the entire box-in process smoother and more efficient.

[0053] In some embodiments, the anti-falling driving device includes a bracket guide rail 6, a bracket slider 7, a bracket driving gear 8, and a bracket driving cylinder 9; the bracket guide rail 6 is fixed to the first mounting frame 3; the bracket slider 7 is slidably connected to the bracket guide rail 6, and a rack is provided on its lower end face; the bracket driving gear 8 is coaxially and fixedly connected to one end of the side bracket 5 and meshes with the rack; the bracket driving cylinder 9 is fixed to the first mounting frame 3 and is used to drive the bracket slider 7 to linearly reciprocate along the bracket guide rail 6, so that the side bracket 5 is lowered or retracted.

[0054] Specifically, when it is necessary to lower the side bracket 5 to prevent the battery module from falling, the bracket driving cylinder 9 pushes the bracket slider 7 to move forward along the bracket guide rail 6. Due to the meshing relationship between the rack and the bracket driving gear 8, the bracket driving gear 8 rotates accordingly, and then drives the side bracket 5 to lower; conversely, when it is necessary to retract the side bracket 5, the bracket driving cylinder 9 pulls the bracket slider 7 to move backward, and the side bracket 5 is also retracted accordingly. Through the cooperation of the bracket guide rail 6, the bracket slider 7, the bracket driving gear 8 and the bracket driving cylinder 9, the anti-falling mechanism can work more stably and reliably, prevent the battery module from falling during the clamping and subsequent operations, and enhance the stability and safety of the equipment.

The Y-direction clamping component includes a Y-direction clamping beam 13, a Y-direction guide rail and a Y-direction driving cylinder 14. The Y-direction guide rail and the Y-direction driving cylinder 14 are respectively fixed to the first mounting frame 3. The Y-direction clamping beam 13 is slidably connected to the Y-direction guide rail. The Y-direction driving cylinder 14 drives the Y-direction clamping beam 13 to slide along the Y-direction guide rail to achieve clamping of the battery module in the Y direction.

[0056] Specifically, the X-direction clamping beam 10 is slidably connected to the X-direction guide rail 11 and can slide along the X-direction guide rail 11 under the drive of the X-direction driving electric cylinder 12. When it is necessary to clamp the battery module, the X-direction driving electric cylinder 12 drives the two X-direction clamping beams 10 to move relatively and clamp the battery module from both sides; the Y-direction clamping beam 13 is slidably connected to the Y-direction guide rail and can slide along the Y-direction guide rail under the drive of the Y-direction driving cylinder 14. When it is necessary to clamp the battery module, the Y-direction driving cylinder 14 drives the two Y-direction clamping beams 13 to move relatively and clamp the battery module from both sides; through the cooperation of the X-direction clamping mechanism and the Y-direction clamping mechanism, precise clamping and positioning of the battery module in the X direction and the Y direction can be achieved, ensuring the stability of the battery module in subsequent operations.

The plug column is provided with a ball 21 elastically connected radially outward. The plug column is inserted and matched with the detection ring seat 19. When the ball 21 passes through the limiting convex ring, it is pressed back, and the signal feedback wire outputs a switch signal, indicating that the pressing is not in place.

[0058] Specifically, the X-direction clamping beam 10 realizes the quick connection or disassembly of the pressing beam 16 and the base beam 15 through the quick-change mechanism. The pin rod 17 is fixed to the pressing beam 16 and is inserted and matched with the lock sleeve 18 on the base beam 15 and is fixedly penetrated radially by a bolt. The quick-change mechanism enables the pressing beam 16 to be quickly connected or disassembled from the base beam 15, improving the replacement efficiency and reducing the maintenance cost. The detection component is used to monitor the pressing state of the pressing beam 16. When the pressing is not in place, the ball 21 on the detection plug 20 will be pressed back by the limiting convex ring in the detection ring seat 19, triggering a switch signal, providing an intuitive feedback for the operator to timely discover and handle problems.
