Description

Technical Field

[0001] This invention relates to a battery stacking transfer device, belonging to the field of battery transfer technology. Background Technology

[0002] In automated battery production lines, the stacking and transfer of battery packs and separators is a crucial step. Existing stacking devices typically employ simple robotic arms or clamps, which have several shortcomings: First, when alternating the gripping of materials from different locations (such as a double-layer conveyor line), positioning accuracy is difficult to guarantee, especially when running at high speeds, the vibration or inertia of the equipment can cause the gripping point to deviate.

[0003] Secondly, and more importantly, most existing equipment uses a single-cycle "pick-place-pick-place" mode, meaning that only one battery pack or separator can be moved to the target location at a time. This makes it impossible to achieve "connected stacking gripping" where multiple battery packs and separators are pre-stacked on the gripper before being transferred in one go. This working mode results in a large number of round trips for the robotic arm, a slow overall work cycle, and severely restricts the improvement of production efficiency.

[0004] Furthermore, even during a single placement process, when one material (such as a battery pack) is placed on top of another material (such as a separator), the slight displacement during the release process can easily lead to misalignment and uneven stacking, affecting the smooth progress of subsequent packaging processes and the quality of the final product.

[0005] Therefore, how to design a device that can achieve fast, stable, and high-precision alternating material handling, connection and stacking, and ensure centered placement is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a battery storage stacking transfer device. This device can realize the "connection stacking gripping" of battery packs and separators, transfer them in one go after pre-forming the stack on the clamping mechanism, and ensure high-precision centering alignment during the stacking process.

[0007] The energy storage stacking transfer device of the present invention includes: A load-bearing frame, on which rails are provided; A crane vehicle, which is mounted on the track and is capable of moving along it; A lifting column, wherein the lifting column is movably mounted on the crane vehicle; A swing mechanism, which is connected to the lower end of the lifting column; A clamping mechanism, connected to the lower end of the swing mechanism, is used to clamp the battery pack or separator; The swing mechanism is used to drive the clamping mechanism to switch between at least two preset clamping positions; The centering mechanism is used to apply a pushing force toward the center to the battery pack or the separator when the clamping claws open to both sides during the process of placing the battery pack above the separator by the clamping mechanism.

[0008] Through the coordinated operation of the above structures, this device can first clamp a first type of material (such as a battery pack), and then, without releasing the first material, switch positions via a swing mechanism and be driven by a lifting column to clamp a second type of material (such as a partition) below it. This process is repeated to form a suspended multi-layered stack on the clamping mechanism, which is then transported and placed in one go by a crane. The centering mechanism performs precise centering correction each time material is placed, ensuring the quality of the stack.

[0009] Furthermore, the clamping mechanism includes: A clamping frame, which is connected to the lower end of the swing mechanism; At least two mirror-symmetrically arranged clamping jaws are obliquely and slidably connected to both ends of the clamping frame; An elastic element, connected between the clamping frame and the clamping jaws, is used to provide an elastic force that brings the clamping jaws together. The lower end of the clamping claw is provided with a guide slope. When the clamping mechanism descends, the guide slope contacts the upper edge of the battery pack or separator to be clamped, thereby causing the clamping claw to open to both sides.

[0010] Furthermore, the clamping claw is also provided with a support surface for supporting the battery pack or separator. One end of the support surface is a downwardly extending guide slope. A support wheel is provided at the transition between the support surface and the guide slope. The support wheel is used to roll along the outer wall of the battery pack or separator.

[0011] Furthermore, the centering mechanism includes: The centering rod is hinged to the inner side of the clamping frame via two parallel elastic telescopic rods; The positioning part is provided at the lower end of the centering rod. The positioning part slides against the support surface at the upper end of the clamping claw. When the two clamping claws move away from each other, the centering rod moves closer to each other.

[0012] Furthermore, when the support wheel rolls along the outer wall of the battery pack or separator, the working surface of one end of the centering rod abuts against the outer wall of the battery pack or separator.

[0013] Furthermore, the device also includes a locking mechanism, which is disposed at a predetermined position on the track and is used to lock the hoisting vehicle on the track when the clamping mechanism performs clamping operations; The locking mechanism includes: A locking block is installed on the load-bearing frame and has locking grooves for the wheel axles of the hoisting vehicle to engage. A pressure block, which is hinged to the locking block; A locking cylinder, which is mounted on the load-bearing frame, has its telescopic end hinged to the pressure block, and is used to drive the pressure block to rotate to press or release the wheel axle.

[0014] Furthermore, a helical rack is installed on the lifting column, and a lifting motor is installed on the hoisting vehicle. The output end of the lifting motor is connected to a helical gear that meshes with the helical rack. The lifting column is slidably connected to the hoisting vehicle via a slide rail installed on it.

[0015] Furthermore, the swing mechanism includes: At least one set of parallel swing rods, the upper end of which is hinged to the lower end of the lifting column, and the lower end of which is hinged to the clamping mechanism; The lifting column is provided with a positioning plate for limiting the first position of the swing rod and a positioning block for limiting the second position of the swing rod; It also includes a locking cylinder for driving the swing arm to swing between the first position and the second position.

[0016] Furthermore, the swing mechanism also includes swing frames hinged at both ends of the swing rod, and the swing mechanism is installed at the lower end of the lifting column and the upper end of the clamping mechanism through the swing frames at both ends.

[0017] Furthermore, it also includes a rotating mechanism for connecting the swinging mechanism and the clamping mechanism, comprising: A fixed plate is connected to the swing frame, and a rotating cylinder is fixed on the fixed plate. The telescopic end of the rotating cylinder is connected to a rotating cylinder, and the rotating cylinder is connected to the clamping mechanism.

[0018] Compared with the prior art, the beneficial effects of the present invention are: This invention enables interconnected stacking, significantly improving efficiency: Unlike the traditional "take one, put one" mode, this invention pre-stacks multiple battery packs and separators on the clamping mechanism and then performs a one-time transfer, greatly reducing the number of trips of the crane, shortening the work cycle, and multiplying production efficiency.

[0019] Precise positioning and high stacking quality: The locking mechanism ensures the stability of the reference during material picking, and the swing mechanism enables precise switching of the picking point. In particular, the unique centering mechanism performs real-time centering correction when placing materials, which fundamentally solves the problem of stacking misalignment and significantly improves stacking quality.

[0020] Ingenious structure, energy saving and reliable: The clamping mechanism adopts a gravity and elastic element driven design without power. It achieves adaptive opening and closing through the guide slope, without the need for an additional driving source. This not only reduces energy consumption, but also simplifies the structure, reduces failure points, and improves the stability and reliability of operation.

[0021] Automation and Intelligence: This device integrates functions such as movement, lifting, swinging, clamping, and alignment into one unit, realizing a fully automated stacking process. The adaptive opening of the clamping mechanism and the linkage alignment of the alignment mechanism demonstrate the intelligence of the design and reduce reliance on complex sensors.

[0023] Example 1 like Figures 1-9 As shown, the energy-storage stacking transfer device of the present invention has an overall frame composed of a stable load-bearing frame 1, which provides a high-level installation platform and operating foundation for the entire device. The hoisting vehicle 2, as the execution unit for XY plane motion, can move horizontally on the track 11 of the load-bearing frame 1 via its wheels, thereby covering the entire working area and enabling flexible scheduling from the material handling station to the transfer platform. To achieve vertical (Z-axis) movement, the lifting column 3 is precisely slidably connected to the hoisting vehicle 2 via a slide rail 32, ensuring the smoothness and guidance of the lifting process. Its lifting action is driven by a lifting motor 4, which meshes with a helical gear 31 fixed on the lifting column 3. This gear and rack transmission method has the advantages of precise transmission ratio, strong load-bearing capacity, and smooth operation, and is particularly suitable for applications requiring high lifting and positioning accuracy.

[0024] To overcome the slight displacement of the hoist 2 that may occur due to inertia or vibration when gripping heavy objects (such as battery pack 100), and thus ensure absolute accuracy in material handling positioning, this device is equipped with a locking mechanism 5 on the track 11 at the material handling station. Figure 1 As shown, when the crane 2 precisely reaches the designated material-picking position via servo control, its wheel axle 21 naturally falls into the locking groove 52 of the locking block 51 fixed on the load-bearing frame 1, achieving initial mechanical limiting. Subsequently, the locking cylinder 54 actuates, its telescopic end pushing the hinged pressure block 53, using leverage to firmly press the wheel axle 21 into the locking groove 52. This dual-protection mechanism of "positioning first, then locking" completely eliminates any potential shaking of the crane 2 during subsequent lifting, swinging, and clamping processes, providing a rock-solid stable foundation for achieving high-precision stacking.

[0025] The lower end of the lifting column 3 is connected to the entire clamping unit via a sophisticated swing mechanism 6. For example... Figure 3As shown, the main body of the swing mechanism 6 consists of a parallel swing rod 61 and swing frames 63 at both ends, forming a classic parallelogram linkage mechanism. The core advantage of this structure is that, regardless of the swing angle of the swing rod 61, the lower swing frame 63 (and its connected clamping mechanism 7) can always maintain a parallel state with the upper mounting reference surface (i.e., the ground), ensuring that the clamping mechanism 7 is always horizontal when approaching the material. The locking cylinder 62 serves as the drive source, and its range of motion is precisely defined by the positioning plate 33 (first position) and the positioning block 34 (second position) on the lifting column 3. Through the extension and retraction of the cylinder, the clamping mechanism 7 can be driven to quickly and accurately switch between these two fixed horizontal positions determined by mechanical hard limits, thereby accurately corresponding to the center lines of the battery pack 100 of the lower conveyor line and the partition 200 of the upper conveyor line, respectively.

[0026] To achieve a better lever arm and smoother driving effect, the locking cylinder 62 is not driven directly by the swing arm 61. Specifically, as shown in... Figure 3 As shown, the lower end of the lifting column 3 is hinged to a locking cylinder 62, and a connecting rod 64 is also hinged to the lifting column 3 above the locking cylinder 62. A pull rod 65 is hinged to the lower end of the connecting rod 64, and the other end of the pull rod 65 is hinged to the lower swing frame 63. The telescopic end of the locking cylinder 62 is cleverly hinged to the middle of the connecting rod 64. When the cylinder telescopically extends or retracts, it pushes the connecting rod 64 to swing around its upper fulcrum. The connecting rod 64 then, through the lower pull rod 65, pulls or pushes the entire parallelogram mechanism. This multi-link transmission design transforms the linear motion of the cylinder into a smooth swinging arc motion and may provide a force amplification effect, making the start and stop of the swinging process smoother and reducing impact.

[0027] The clamping mechanism 7 and the centering mechanism 8 are among the core innovations of this invention, demonstrating the ingenuity of mechanical design. For example... Figure 5 , Figure 6 and Figure 7As shown, the clamping mechanism 7 achieves powerless adaptive clamping. Its clamping frame 71 has an inclined groove, where two mirror-symmetrical clamping claws 72 are mounted via sliders. In its natural state, the tension of the elastic element 73 (such as a spring) keeps the two clamping claws 72 in a closed, clamped position. When the device descends, the guide ramp 74 at the lower end of the clamping claws 72 first contacts the upper edge of the battery pack 100. Under the device's own weight, this contact force is decomposed by the guide ramp 74 into a force that forces the clamping claws 72 to slide outward and upward along the inclined groove. During this process, to reduce friction and protect the material surface, the support wheel 76 smoothly rolls along the side wall of the battery pack 100. When the support surface 75 of the clamping claws 72 completely passes the bottom of the battery pack 100, the lateral resistance disappears, and the elastic element 73 immediately pulls the clamping claws 72 back together, so that their support surface 75 reliably supports the battery pack 100 from below. The entire process requires no additional cylinder or motor drive, making it energy-efficient and reliable.

[0028] The centering mechanism 8 cleverly utilizes the movement of the gripping claws 72 to achieve automatic centering. Its linkage logic is as follows: the positioning part 83 of the centering rod 81 always maintains sliding contact with the support surface 75 on the upper part of the gripping claws 72. During the gripping process, when the gripping claws 72 are opened by the material and slide outwards and upwards along the inclined groove, they push the positioning part 83, causing the centering rods 81 on both sides to move closer together under the guidance of the parallel elastic telescopic rods 82. When placing the entire stack, when the bottommost material contacts the platform, the lifting column 3 continues to descend, and the gripping claws 72 are also forced to slide outwards and upwards to release all the material. At this instant, the working surface 84 at the end of the centering rods 81, which have already moved closer together due to the opening of the gripping claws, gently abuts against the battery pack 100 being released from both sides, applying a constraint force to center it, ensuring that the battery pack 100 accurately lands in the center of the lower partition 200 when it is completely detached from the support surface 75. This process is purely mechanically linked, with rapid response and precise positioning.

[0029] In addition, to enhance the process adaptability of the device, this embodiment also includes a rotating mechanism 9. For example... Figure 2 , Figure 8 and Figure 9 As shown, it is integrated between the lower swing frame 63 and the clamping mechanism 7. Its function is that when the materials to be gripped or placed have different orientation requirements (for example, the battery pack needs to be rotated 90 degrees for placement), the rotating cylinder 92 can drive the rotating cylinder 93 to make the entire clamping mechanism 7 together with the centering mechanism 8 rotate at a precise angle (such as 90 degrees), so that it can flexibly cope with diverse production tasks without adjusting the production line layout.

[0030] The transmission principle of the rotating mechanism 9 is a classic conversion from linear motion to rotary motion. The outer wall of the rotating cylinder 93 is machined with precise helical grooves 95. A sliding column 96 is connected to the telescopic end of the rotating cylinder 92. When the telescopic end of the rotating cylinder pushes the sliding column 96 in a linear motion, because the sliding column 96 is constrained within the helical grooves 95, it can only move along the groove's trajectory. This combined motion forces the rotating cylinder 93 to rotate around its central axis. The rotating cylinder 93 is connected to the lower swing frame 63 via a fixed annular plate 94 and screws, thereby driving the entire swing frame 63 and all components below it to rotate together, achieving stable and reliable rotary positioning.

[0031] Working principle of the invention: The principle of self-adaptive clamping and centering without power: The core execution unit of the device—the clamping mechanism 7—does not rely on traditional cylinders or motor drives, but cleverly utilizes the conversion of gravitational potential energy and elastic potential energy. During descent, the device's own weight is converted into a force that causes the clamping claws 72 to open outward through the guide ramp 74, overcoming the pressure of the elastic element 73 and achieving adaptive "claw opening." After passing the bottom of the material, the elastic potential energy stored in the elastic element 73 is released, driving the clamping claws 72 to quickly retract, completing the "claw closing" clamping. Simultaneously, the centering mechanism 8, as an accompanying mechanism of the clamping mechanism, is entirely determined by the position of the clamping claws 72, forming a purely mechanical linkage. The opening of the clamping claws 72 inevitably leads to the closing of the centering rod 81, thus automatically applying a centering and corrective force to the material at the moment of release, achieving precise centering during placement. This entire mechanism is highly integrated, energy-saving, and reliable.

[0032] The principle of aerial pre-stacking under multi-mechanism collaboration: This invention achieves "connected stacking gripping" through the precise timing coordination of the lifting column 3, the swing mechanism 6, and the clamping mechanism 7. The logic is as follows: After each gripping action, the lifting column 3 raises the clamping mechanism 7 to a safe height. At this time, the clamping mechanism 7 does not release the clamped material but moves quickly and accurately above the next picking point via the swing mechanism 6. The lifting column 3 then descends again, and the clamping mechanism 7, with its unique powerless method, continues to grip new material below the already clamped material. This cycle repeats, forming a stack of materials layered from bottom to top on the clamping mechanism 7 in mid-air. This "pre-stacking in mid-air first, then one-time overall handling" mode overturns the traditional inefficient "one-to-one" operation method. The entire process is uniformly scheduled by a PLC (Programmable Logic Controller), ensuring seamless connection and coordinated operation of various action units (such as the movement of the crane 2, the lifting of the lifting column 3, the swinging of the swinging mechanism 6, and the opening and closing of the locking mechanism 5).

[0033] The core of the workflow of this invention lies in "connected stacked grasping", and the specific steps are as follows: Positioning and locking: When the crane 2 moves above the material handling station, its wheel axle 21 enters the locking groove 52, and the locking mechanism 5 locks the crane 2 firmly.

[0034] Grabbing the first material: The locking cylinder 62 is activated, causing the swing mechanism 6 to swing to the location of the first material (e.g., the battery pack 100 of the lower conveyor line). The lifting column 3 descends, and the clamping mechanism 7 automatically opens and clamps a battery pack 100 before rising.

[0035] Clamping the second material and forming a stack: The locking cylinder 62 reverses its action, causing the swing mechanism 6, which is already clamping the battery pack 100, to swing to the location of the second material (e.g., the partition 200 of the upper conveyor line).

[0036] The lifting column 3 descends again, and the clamping mechanism 7 clamps a partition 200 in the same way and then rises, firmly clamping the partition 200 under the existing battery pack 100.

[0037] Repeated stacking: According to the preset program, repeat the above clamping steps to form a suspended stack of separators and battery packs alternating from bottom to top on the clamping mechanism 7 (e.g., separator-battery pack-separator-battery pack...).

[0038] Transfer: Once the preset stacking quantity is reached, the locking mechanism 5 unlocks, and the crane 2, carrying the entire suspended stack, quickly moves to the top of the packaging platform.

[0039] Overall Placement: The lifting column 3 descends, placing the entire stack at the target position. During descent, as the bottom partition contacts the platform, the gripping claws 72 open to release all materials. At this instant, the centering mechanism 8 applies a centering force to each layer of material, ensuring that the entire stack remains precisely aligned upon final release.

[0040] Cycle: After placement is complete, the device returns to its initial position and begins the next efficient cycle of "connection stack-transfer-placement".

[0041] The descriptions of the orientation and relative positional relationships of the structures in this invention, such as front, back, left, right, up, and down, do not constitute a limitation of this invention, but are merely for the convenience of description.
