Description

Technical Field

[0001] This invention relates to a lithium metal casting and stacking system, and pertains to the technical field of lithium metal production and processing equipment. Background Technology

[0002] Lithium metal is an extremely reactive alkali metal that reacts violently with moisture, oxygen, and nitrogen in the air, potentially causing combustion or explosion. Therefore, the casting, molding, cooling, and stacking processes of lithium metal are typically carried out in a sealed environment or glove box filled with inert gas (such as argon).

[0003] In existing lithium metal production processes, the stacking of cast lithium ingots largely relies on manual handling through glove boxes. This process is labor-intensive, inefficient, and exposes operators to significant safety risks. Existing mechanical grippers struggle to precisely control the clamping force when holding lithium ingots. Excessive force can damage and deform the soft surface of the lithium metal, while insufficient force can lead to slippage during movement, causing safety hazards and product spoilage. Furthermore, existing stacking robotic arms have a simplistic structure, making it difficult to achieve flexible lateral and vertical movement and precise adjustment of stacking angles within a confined space, thus failing to meet the requirements for stacking complex pile types. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a lithium metal casting and stacking system.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0006] A lithium metal casting and stacking system includes a casting component, a housing on one side of the casting component, the side of the housing communicating with the interior of the casting component, and the housing being a cavity structure with openings on both sides.

[0007] The housing is equipped with a gripping component for gripping and stacking shaped lithium metal. A moving component is connected above the gripping component and is connected to the housing to drive the gripping component to move within the housing.

[0008] The gripping component includes two sets of symmetrically arranged horizontal plates. The top of the two sets of horizontal plates is connected to a fixed plate. The bottom of the horizontal plates is provided with multiple sets of fixed plates. The bottom of the fixed plates is connected to a rectangular plate through a connecting column. Each side of the top of the rectangular plate is provided with a support. A clamping arm is rotatably connected to the support. The clamping arm can rotate relative to the support to realize the gripping and releasing action.

[0009] Preferably, the housing has an observation window at one side opening and a sealed protective door at the other side opening; the observation window has multiple operating ports, each of which is equipped with a glove, and a sealing component is provided at the connection between the glove and the observation window.

[0011] Preferably, the bottom end of the clamping arm is provided with a groove, and a secondary clamp is rotatably connected in the groove via a rotating shaft; a connecting block is provided on the opposite side of the secondary clamp, and an upwardly inclined connecting arm is rotatably connected to the opposite side of the connecting block; a movable rod is rotatably connected to the top of the connecting arm, and the movable rod is fixedly connected to one side of the driven gear.

[0012] Preferably, the connecting arm is rotatably connected to the movable rod and the connecting block respectively by a pin;

[0013] Both the clamping arm and the auxiliary clamp have rubber pads on their inner sides.

[0014] Preferably, the bottom of the fixed disk is provided with a drive motor three, the output end of the drive motor three is connected to a worm gear, and the worm gear meshes with each worm wheel.

[0015] Preferably, the movable component includes a transversely arranged crossbeam, with a movable seat fitted on the outer wall of the crossbeam, and a slide rail that slides with the crossbeam inside the movable seat; an L-shaped bracket is provided on one side of the crossbeam, and the free end of the L-shaped bracket is rotatably connected to a fixed plate through a pin seat.

[0016] Preferably, the top of the L-shaped bracket is movably connected to an electric telescopic rod, and the output end of the electric telescopic rod is rotatably connected to the top of one of the horizontal plates.

[0017] Preferably, the top of the crossbeam is provided with a rack extending along its length, the rack being meshed with a gear, and the top of the movable seat is provided with a drive motor for driving the gear to rotate.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figure 1-10 This invention provides a technical solution for a lithium metal casting and stacking system, including a casting component 1. The system is characterized in that a housing 2 is provided on one side of the casting component 1, and the side of the housing 2 communicates with the interior of the casting component 1, allowing the formed lithium metal to smoothly enter the housing 2. The housing 2 is a cavity structure with openings on both sides, filled with an inert protective gas. The housing 2 is a cavity structure with openings on both sides.

[0038] The housing 2 is equipped with a gripping component for gripping and stacking shaped lithium metal inside. A moving component is connected above the gripping component. The moving component is connected to the housing 2 and is used to drive the gripping component to move inside the housing 2.

[0039] The gripping assembly includes two sets of symmetrically arranged horizontal plates 7. The top of the two sets of horizontal plates 7 is connected to a fixed plate 8. The bottom of the horizontal plates 7 is provided with multiple sets of fixed disks 9. The bottom of the fixed disks 9 is connected to a rectangular plate 11 through a connecting column 10. Each side of the top of the rectangular plate 11 is provided with a support 12. A clamping arm 17 is rotatably connected to the support 12. The clamping arm 17 can rotate relative to the support 12 to realize the clamping and releasing action.

[0040] See Figure 1-10 The housing 2 has an observation window 3 at one side opening and a sealed protective door 4 at the other side opening. Multiple operating ports are provided on the observation window 3, and each operating port is equipped with a glove 5. A sealing component 6 is provided at the connection between the glove 5 and the observation window 3. This ensures that the inert gas atmosphere inside the housing 2 is not disrupted during operation.

[0041] The support 12 is equipped with a worm gear 13, which is rotatably connected to the support 12 via a rotating shaft 14. A transmission gear is sleeved on the rotating shaft 14, and a driven gear 15 is meshed with one side of the transmission gear. The driven gear 15 is rotatably connected to the support 12 via a rotating shaft 16. Both ends of the rotating shaft 16 pass through the support 12 and are connected to the clamping arm 17, which is inclined downwards. When the driven gear rotates, it drives the clamping arm to swing inwards via the rotating shaft 16, and simultaneously pulls the auxiliary clamp inwards via the movable rod and connecting arm, achieving double-layer wrapping clamping by the clamping arm and auxiliary clamp. The rubber pad fully covers the clamping contact surface of the clamping arm and auxiliary clamp, buffering the clamping pressure.

[0042] See Figure 1-10 The bottom end of the clamping arm 17 is provided with a groove, and a secondary clamp 18 is rotatably connected to the groove through a rotating shaft 19. A connecting block 20 is provided on the opposite side of the secondary clamp 18. A connecting arm 21 that is inclined upward is rotatably connected to the opposite side of the connecting block 20. A movable rod 22 is rotatably connected to the top of the connecting arm 21. The movable rod 22 is fixedly connected to one side of the driven gear 15.

[0043] The connecting arm 21 is rotatably connected to the movable rod 22 and the connecting block 20 respectively by pins;

[0044] Both the clamping arm 17 and the auxiliary clamp 18 are provided with rubber pads 23 on their inner sides.

[0045] The bottom of the fixed disk 9 is provided with a drive motor 24, and the output end of the drive motor 24 is connected to a worm gear 25, which meshes with each worm wheel 13.

[0046] See Figure 1-10 The moving component includes a horizontally arranged crossbeam 26, with a movable seat 27 fitted on the outer wall of the crossbeam 26. The movable seat 27 has a slide rail 28 that slides with the crossbeam 26. An L-shaped bracket 29 is provided on one side of the crossbeam 26, and the free end of the L-shaped bracket 29 is rotatably connected to the fixed plate 8 through a pin seat 30.

[0047] The top of the L-shaped bracket 29 is movably connected to an electric telescopic rod 31, and the output end of the electric telescopic rod 31 is rotatably connected to the top of one of the horizontal plates 7.

[0048] The top of the crossbeam 26 is provided with a rack 32 extending along its length, and the rack 32 is meshed with a gear 33. The top of the movable seat 27 is provided with a drive motor 34 for driving the gear 33 to rotate.

[0049] See Figure 1-10 The movable seat 27 has a vertically arranged vertical frame 35 on its back, and two sets of slide rails 36 on the side of the vertical frame 35. The movable seat 27 has a slider that slides in cooperation with the slide rails 36.

[0050] A rack 37 extending along the length of the vertical frame 35 is located on one side and between two sets of slide rails 36. The rack 37 is meshed with a gear 38. A drive motor 39 is provided on the movable seat 27 to drive the gear 38 to rotate. The output gear of the drive motor meshes with the rack, driving the movable seat to move up and down along the vertical frame in the Z direction. An L-shaped bracket is fixed to the side of the crossbeam. The lower end of the L-shaped bracket is hinged to the fixed plate of the gripping assembly through a pin seat. An electric telescopic rod is hinged to the top of the L-shaped bracket. The output end of the electric telescopic rod is hinged to a horizontal plate. The extension and retraction of the electric telescopic rod can drive the entire gripping assembly to rotate around the pin seat, adjusting the tilt angle of the lithium ingot stacking.

[0051] In use, after the casting and molding component 1 completes the casting of lithium metal and cools and solidifies, the lithium metal ingot is transported to the gripping station inside the housing 2.

[0052] Vertical movement (Z-axis): Drive motor 2 39 starts, driving gear 2 38 to roll on rack 2 37, thereby driving movable seat 27 to move up and down along slide rail 2 36 on vertical frame 35, adjusting the height of gripping component.

[0053] Lateral movement (X-axis): Drive motor 34 starts, driving gear 33 to roll on rack 32, thereby driving movable seat 27 to move left and right along slide rail 28 on crossbeam 26, so that gripping component is precisely suspended above the lithium metal ingot.

[0054] When drive motor 24 starts, it drives worm gear 25 to rotate, which in turn drives each worm wheel 13 to rotate synchronously. The worm wheel 13 drives shaft 14 and transmission gear to rotate, and the transmission gear drives driven gear 15 to rotate.

[0055] Driven gear 15 drives clamping arm 17 to retract inward via rotating shaft 2 16. Simultaneously, driven gear 15 drives movable rod 22 to perform eccentric motion, which pulls connecting arm 21. Connecting arm 21, through connecting block 20, pulls auxiliary clamp 18 to rotate inward around rotating shaft 3 19. Finally, clamping arm 17 and auxiliary clamp 18 close synchronously, securely holding the lithium ingot through inner rubber pad 23. Due to the self-locking characteristic of the worm gear mechanism, the clamping force will not disappear when power is cut off or the machine stops.

[0056] The moving component moves the gripping component holding the lithium metal ingot to the target stacking position. During the placement process, if it is necessary to adjust the placement angle of the lithium metal ingot, the electric telescopic rod 31 can be extended or retracted. The electric telescopic rod 31 pushes the horizontal plate 7, causing the fixed plate 8 and the entire gripping component to tilt and rotate around the pin seat 30, thereby precisely adjusting the stacking posture.

[0057] After placement, drive motor 24 reverses, clamping arms 17 and auxiliary clamps 18 open, releasing the lithium metal ingot. Throughout the operation, the operator can monitor the condition inside the housing 2 in real time through the observation window 3; in case of emergencies such as material jamming, the operator can put their hands into gloves 5 with sealing components 6 to make manual adjustments without disrupting the inert gas environment inside the housing 2, ensuring production safety.

[0058] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
