Description

Technical Field

[0001] The present invention relates to the technical field of stacking systems, and in particular to a high-efficiency stacking system for lithium batteries. Background Art

[0002] The stacking system plays a vital role in modern industrial production and logistics management. It not only improves the utilization rate of warehouse space, but also significantly improves the efficiency of cargo storage and retrieval. With the development of automation technology, automated stacking systems have become an indispensable part of modern logistics centers, manufacturing plants and even the retail industry. These systems integrate advanced sensors, control systems and mechanical devices to achieve efficient management and rapid response to various types of goods, greatly promoting the progress of Industry 4.0. Especially when dealing with large-scale, highly repetitive tasks, automated stacking systems can significantly reduce labor costs and improve operational accuracy and safety.

[0003] In recent years, driven by the new energy industry, the large-scale production of lithium batteries has put forward higher requirements on the warehousing system. Stackers have gradually become key equipment in the lithium battery storage link with their customizable shelf layout, multi-dimensional motion control and high load capacity (usually up to 1-5 tons), effectively solving the challenges of heavy weight of battery modules, multiple specifications and strict storage environment requirements.

[0004] However, as shown in patent CN113772591A, traditional stackers usually rely on fork structures to complete the handling and storage of goods, especially when handling heavy goods such as lithium batteries, the structural complexity is greatly increased. In order to ensure the smoothness and safety of operation, traditional designs often need to be equipped with complex mechanical components, such as hydraulic drive, multiple sensor monitoring, etc., which not only increases the cost of the equipment, but also increases the difficulty of maintenance and failure rate. For goods such as lithium batteries that have special shapes and weight distributions, the existing fork structure is difficult to provide sufficient support and stability, which can easily cause the goods to slip or be damaged, thereby affecting the operating efficiency of the entire system. Therefore, how to design a stacking system that is both simple and reliable to meet the needs of efficient and safe handling of heavy goods such as lithium batteries has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a lithium battery efficient stacking system that can reduce the structural complexity of the stacker and ensure safety and reliability.

[0006] Technical solution: To achieve the above-mentioned purpose, the lithium battery efficient stacking system of the present invention comprises a track system, a stacker, a handling robot and a stacking shelf; the track system comprises a ceiling track and a floor track;

[0007] The stacker has a vertical frame and a lifting mechanism capable of moving up and down along the vertical frame; the upper and lower sides of the vertical frame are respectively provided with an upper traveling wheel mechanism and a lower traveling wheel mechanism capable of moving along the upper rail and the lower rail.

[0008] The lifting mechanism includes a lifting frame, and two first tracks for the stacker to enter and exit are installed on the lifting frame. Both ends of the first track are respectively provided with a holding mechanism, and the holding mechanism includes a rotating part capable of rotating relative to the first track.

[0009] The stacking shelf has a storage unit, the storage unit has a battery support frame, the middle of the battery support frame has a concave part, and the bottom of the concave part has a second track.

[0010] The rotating part can be switched between a flat state and an inclined state. In the inclined state, the rotating part has a part higher than the first track to form a blocking effect on the handling robot on the lifting frame, preventing the handling robot from falling off the lifting frame; in the flat state, the rotating part is in a horizontal state, and it connects the first track and the second track, so that the handling robot can move from the lifting frame to the concave part and place the lithium battery on the battery support frame.

[0011] Further, the vertical frame is a gantry structure with an upper cross beam and two columns; the picking and placing mechanism has two lifting seats capable of moving up and down relative to the two columns respectively, and the lifting frame is erected between the two lifting seats; a driving mechanism for respectively driving the two lifting seats is installed on the vertical frame.

[0012] Adopting this structure can make the lifting frame run smoothly and improve the reliability of the stacker operation.

[0013] Further, the holding mechanism further includes a connecting rod connecting the rotating part, and further includes a slider slidably installed relative to the lifting frame. Both ends of the connecting rod are respectively rotatably connected to the rotating part and the slider; the holding mechanism further includes a driving device for driving the slider to slide.

[0014] Adopting the above structure, by driving the slider to slide back and forth, the state switching of the rotating part can be realized.

[0015] Further, the driving device includes two lead screws and lead screw nuts installed on each of the sliders;

[0016] The two lead screw nuts corresponding to the two sliders at both ends of the same first track cooperate with both ends of the same lead screw, and both ends of the lead screw have two helical parts with opposite helix directions;

[0017] The driving device further includes a transmission shaft disposed between the two lead screws and perpendicularly arranged to the lead screws; a transmission relationship is established between the transmission shaft and each lead screw through a bevel gear set; one of the lead screws is driven by a driving motor to operate.

[0018] With the above structure, the driving motor can make the four rotating parts rotate synchronously to switch states.

[0019] Further, the stacking rack has a main frame body, and the storage units are arranged in a square array on the main frame body.

[0020] Further, both sides of the storage unit are respectively provided with a first chute member with a downward opening and a second chute member with an upward opening; the main frame body is provided with a support plate corresponding to each storage unit, and the first chute member and the second chute member are respectively matched with the upper and lower edges of the support plate.

[0021] Further, both ends of each first chute member and both ends of each second chute member are provided with detachable retaining pins.

[0022] With the above structure, the storage unit can be conveniently installed on the main frame body and fixed. Specifically, first, the first chute member and the second chute member are matched with the upper and lower edges of the support plate, the storage unit is slid into the main frame body, and then the retaining pins are inserted to limit both ends of each first chute member and the second chute member to prevent the storage unit from sliding relative to the main frame body. In this way, the assembly difficulty can be reduced.

[0023] In addition, a support block is fixed on one side of the storage unit facing the moving lane of the stacker. When the lifting mechanism is aligned with the storage unit and the rotating part is in a flat state, the outer end of the rotating part is lapped on the support block. In this way, when the handling robot passes through the rotating part, the rotating part can be reliably supported.

[0024] Beneficial effects: The high-efficiency lithium battery stacking system of the present invention has the following beneficial effects:

[0025] (1) The high-efficiency lithium battery stacking system of the present invention makes full use of the moving ability and lifting ability of the handling robot to store the lithium battery, reduces the structural complexity of the lifting mechanism, and during the process of placing the lithium battery into the storage unit, the vertical frame does not need to bear a strong overturning moment, ensuring the safety of the system.

[0026] (2) Through the collaborative work of the rail system, stacker, handling robot, and stacking shelves, the efficient storage and handling of lithium batteries are achieved. The rotating part in the lifting mechanism is ingeniously designed and can switch between the horizontal and inclined states, ensuring the safety of the handling robot during the lifting process, preventing it from falling, and at the same time enabling the smooth transfer of the handling robot in the horizontal state, improving the operation efficiency and safety of the system.

The rotating part 24 in the lifting mechanism 2 is ingeniously designed and can be switched between a flat state and an inclined state, ensuring the safety of the handling robot C during the lifting process, preventing it from falling, and at the same time realizing the smooth transfer of the handling robot C in the flat state, improving the operation efficiency and safety of the system.

[0044] Preferably, the vertical frame 1 is a gantry structure having an upper cross beam 12 and two columns 11; the picking and placing mechanism 2 has two lifting seats 22 that can respectively move up and down relative to the two columns 11, and the lifting frame 21 is erected between the two lifting seats 22; a driving mechanism 9 for respectively driving the two lifting seats 22 is installed on the vertical frame 1.

The two ends of the connecting rod 25 are respectively rotatably connected to the rotating part 24 and the slider 26; the holding mechanism further includes a driving device 27 for driving the slider 26 to slide.

[0054] Preferably, detachable retaining pins 37 are provided at both ends of each first chute member 35 and both ends of each second chute member 36.

[0055] With the above structure, the storage unit 3 can be conveniently installed on the main frame body and fixed. Specifically, first, the first chute member 35 and the second chute member 36 are matched with the upper and lower edges of the support plate 81, the storage unit 3 is slid into the main frame body 8, and then the retaining pins 37 are inserted to limit both ends of each first chute member 35 and the second chute member 36 to prevent the storage unit 3 from sliding relative to the main frame body 8. In this way, the assembly difficulty can be reduced.
