For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0031] Please also refer to Figure 1-3This utility model provides a lithium battery cell flipping and unloading device, including a flipping mechanism driven by a flipping motor (1), a conveying mechanism driven by a conveying motor (3), and a lifting mechanism driven by a lifting motor (5). The conveying mechanism is located on one side of the output end of the flipping mechanism, and the lifting mechanism is located on one side of the output end of the conveying mechanism.

[0032] The flipping mechanism includes a flipping frame (21), a clamp assembly disposed on the flipping frame (21), a forward and backward guide rail (22) disposed on one side of the flipping frame (21), and a forward and backward motor (23) that drives the flipping frame (21) to reciprocate on the forward and backward guide rail (22).

[0033] The clamping assembly includes a clamping motor (241), an opening and closing guide rail (242), an opening and closing guide plate (243), a ball screw (244), a clamping guide rail (246), an upper opening and closing plate (247), a lower opening and closing plate (248), and several upper clamping plates (249) and several lower clamping plates (250).

[0034] The opening and closing guide rail (242) is horizontally parallel to the outside of the flipping frame (21); the clamping motor (241) is located at one end of the opening and closing guide rail (242), and the opening and closing guide plate (243) is located at the other end of the opening and closing guide rail (242); one end of the opening and closing guide plate (243) is provided with a figure-eight guide groove (2431), and the other end is provided with a screw seat (245). The ball screw (244) is located in the screw seat (245) and is threadedly engaged with the screw seat (245); the output end of the clamping motor (241) is connected to the ball screw (244), so that when the clamping motor (241) rotates, it drives the ball screw (244) to rotate in place, thereby driving the opening and closing guide plate (243) to reciprocate on the opening and closing guide rail (242);

[0035] Several clamp guide rails (246) are vertically arranged inside the flipping frame (21). The upper opening and closing plate (247) and the lower opening and closing plate (248) are horizontally slidably arranged on the clamp guide rails (246). The upper opening and closing plate (247) and the lower opening and closing plate (248) are respectively connected to the opening and closing bearings (251) through connectors. The opening and closing bearings (251) are respectively slidably installed in the figure-eight guide grooves (2431) on the opening and closing guide plate (243).

[0036] Several upper clamping plates (249) are fixedly arranged side by side on the upper opening and closing plate (247), and several lower clamping plates (250) are fixedly arranged side by side on the lower opening and closing plate (248). The upper clamping plates (249) and the lower clamping plates (250) correspond one to one. A pair of upper clamping plates (249) and lower clamping plates (250) form a clamping unit, so that the upper opening and closing plate (247) and the lower opening and closing plate (248) can simultaneously drive several clamping units to open and close, so that the device can clamp several lithium battery cells at the same time.

[0037] The working principle of the fixture assembly is as follows:

[0038] When the clamping motor (241) rotates, it drives the ball screw (244) to rotate in place. The mating thread on the ball screw (244) drives the opening and closing guide plate (243) to reciprocate on the opening and closing guide rail (242). When the opening and closing guide plate (243) reciprocates, it drives the upper opening and closing plate (247) and the lower opening and closing plate (248) to move in opposite directions synchronously through the cooperation of the opening and closing bearing (251) and the figure-eight guide groove (2431), thereby driving the upper clamping plate (249) and the lower clamping plate (250) to open and close, so as to achieve the effect of clamping or releasing the battery cell.

[0039] The conveying mechanism includes a main drive wheel (41), a driven drive wheel (42), and a conveyor belt (43). The conveyor belt (43) is connected between the main drive wheel (41) and the driven drive wheel (42). The main drive wheel (41) is driven by a conveyor motor (3). When the clamping unit is released, the battery cells in the clamping unit are conveyed to the rear end by the conveyor belt.

[0040] The lifting mechanism includes a lifting platform that is slidably mounted on a lifting guide rail (61). The lifting platform is located on one side of the conveyor belt (43), and the lifting platform is driven to lift by a lifting motor (5).

[0041] The working process of the lithium battery cell flipping and unloading device in this case is as follows:

[0042] 1. When the flipping motor (1) starts in the forward direction, the flipping mechanism rotates clockwise and flips outward by 180 degrees, and the flipping motor (1) stops.

[0043] 2. When the clamping motor (241) starts in the forward direction, the opening and closing guide plate (243) moves along the opening and closing guide rail (242) under the threaded engagement of the ball screw (244) and the screw seat (245). Since the figure-eight guide groove (2431) on the opening and closing guide plate (243) engages with the opening and closing bearings (251) on the upper opening and closing plate (247) and the lower opening and closing plate (248) respectively, the upper clamping plate (249) and the lower clamping plate (250) open, and the clamping motor (241) stops.

[0044] 3. When the forward and backward motor (23) starts in the forward direction, the flipping mechanism moves along the forward and backward guide rail (22) and extends to the unloading position of the battery cell winding machine, and the forward and backward motor (23) stops.

[0045] 4. The clamping motor (241) starts in reverse. Under the threaded engagement of the ball screw (244) and the screw seat (245), the opening and closing guide plate (243) moves along the opening and closing guide rail (242). Since the figure-eight guide groove (2431) on the opening and closing guide plate (243) engages with the opening and closing bearings (251) on the upper opening and closing plate (247) and the lower opening and closing plate (248) respectively, the upper clamping plate (249) and the lower clamping plate (250) close to clamp the battery cell, and the clamping motor (241) stops.

[0046] 5. When the forward and backward motor (23) starts in reverse, the flipping mechanism moves back along the forward and backward guide rail (22) and returns to the initial position, and the forward and backward motor (23) stops;

[0047] 6. When the flipping motor (1) starts in reverse, the flipping mechanism rotates counterclockwise and flips inward by 180 degrees, and the flipping motor (1) stops.

[0048] 7. When the clamping motor (241) starts in the forward direction, the upper and lower clamping plates (250) open, the battery cell is released, and the clamping motor (241) stops.

[0049] 8. The conveyor motor (3) starts, and the conveyor belt (43) carries the battery cell to the lifting platform through friction. The conveyor motor (3) then stops.

[0050] 9. The lifting motor (5) starts, the lifting platform descends, reaches the unloading position, the lifting motor (5) stops, the battery cell unloading work is completed, and the battery cell is transferred to the subsequent battery cell cold pressing processing station.

[0051] Compared to existing technologies, the lithium battery cell flipping and unloading device in this case occupies less space, which is conducive to the full utilization of production space and the miniaturization of production equipment; it has a compact structure and low manufacturing and maintenance costs.

[0052] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
