Description

Technical Field

[0001] The utility model relates to the technical field of lithium batteries, in particular to a transfer device for lithium battery production. Background Art

[0002] Lithium battery production is a complex and delicate process involving multiple key steps and processes. Lithium battery production primarily consists of three stages: electrode sheet fabrication, battery cell assembly, and formation and packaging. During the electrode sheet fabrication stage, key processes include slurrying, coating, rolling, slitting, sheeting, and die-cutting, all designed to produce the positive and negative electrode sheets. During slurrying, active materials, conductive carbon, thickeners, binders, additives, and solvents are mixed in a consistent proportion to form a stable suspension, which significantly impacts battery performance. Next comes the battery assembly stage, or the cell manufacturing process. This stage includes winding, hot pressing, X-ray inspection, cell pairing, welding, inserting the insulating base into the case, inserting the cell and BMS into the case, welding the top cover, airtightness testing, vacuum baking, liquid injection, and resting. Winding involves the orderly winding of the positive and negative electrode sheets and separator into a core roll. Welding ensures secure connections within the battery. Airtightness testing uses methods such as helium to check for leaks. The vacuum baking and liquid filling steps are also crucial to battery performance and safety. Finally, the formation and packaging phase comes. This phase includes battery activation, testing, and packaging, aiming to ensure battery safety, reliability, and stable performance. During the formation process, the battery undergoes charge and discharge activation, forming a stable electrochemical system. The packaging process protects the battery's internal structure and prevents damage from the external environment. Lithium battery production also involves a series of quality control and testing steps to ensure that products meet specified standards and requirements at every production stage. These steps, including dimensional measurement, visual inspection, and performance testing, are crucial for improving the overall quality and reliability of the battery. Overall, lithium battery production is a highly integrated and automated process that requires sophisticated equipment and strict process control. With continuous technological advancements and growing market demand, lithium battery manufacturers are continuously expanding their scale and increasing production to meet the growing energy demand.

[0003] The transportation process plays a crucial role in the lithium battery production process, ensuring the smooth flow of raw materials, semi-finished products, and finished products between various links. This process covers the entire process, from the warehousing of raw materials, the transportation of battery cells and electrode coils, to the shipment of finished lithium batteries. First, raw materials such as copper foil, aluminum foil, and electrolyte are precisely measured and inspected before being transported from the warehouse to the production line using specialized transport vehicles such as forklifts or automated guided vehicles (AGVs) according to the production schedule. These raw materials must strictly adhere to safety regulations during transportation to prevent leakage, damage, and contamination. Second, during the battery cell production process, the cells need to be transported from the production line to the next steps, such as formation and capacity separation. During this process, the handling and storage of the cells require extreme care to ensure their integrity and safety. Typically, these cells are precisely handled by automated equipment such as conveyor belts or robotic arms.

[0004] During the production and transportation of lithium batteries, it is necessary to ensure the stability of the transportation process to prevent the lithium batteries from falling and shaking during transportation. However, we consider that it is inconvenient to limit the lithium batteries during traditional transportation, which will cause the lithium batteries to shake during transportation, and further affect the overall quality of the lithium batteries, which is extremely inconvenient. Therefore, a transportation device for lithium battery production is urgently needed to solve the above problems. Utility Model Content

[0008] Preferably, sliders are fixedly connected to both sides of the carrying frame, and both sliders are slidably connected to the inner wall of the frame through slide rails.

[0009] Preferably, a handle is fixedly connected to one side of the frame, and the connection between the output shaft of the hydraulic cylinder and the frame is a sliding connection.

[0013] The utility model has the following beneficial effects:

[0014] When using a transfer device for lithium battery production in the present invention, the lithium batteries to be transferred are first placed one by one into the carrying slots in the carrying frame, and then the hydraulic cylinder is started to drive the entire carrying frame to move upward, so that the tops of all the lithium batteries are close to the limit plate, and the limit plate limits the lithium batteries under the action of elastic damping, thereby protecting the lithium batteries and limiting the lithium batteries to prevent the lithium batteries from shaking during the transportation process. Finally, the entire frame can be pushed.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] Reference Figure 1-5 , a transfer device for lithium battery production, including a frame 1, the frame 1 as the main support and protection structure, carrying other components, the inner side of the frame 1 is slidably connected to the carrier frame 6, the carrier frame 6 can slide up and down inside the frame 1, making the loading and unloading of lithium batteries more convenient, and also providing a working space for the hydraulic cylinder 5, and the bottom of the frame 1 is fixedly connected to the hydraulic cylinder 5, and the output shaft of the hydraulic cylinder 5 passes through the bottom of the frame 1 and is fixedly connected to the bottom of the carrier frame 6, the output shaft of the hydraulic cylinder 5 is directly connected to the carrier frame 6, ensuring that the power generated by the hydraulic cylinder 5 can be directly and accurately transmitted to the carrier frame 6, realizing precise control, the inner side of the carrier frame 6 is opened There are several bearing slots 15, which are designed inside the bearing frame 6 for placing lithium batteries. The size of each bearing slot 15 matches the lithium battery to ensure the stability of the lithium battery during transportation. The top of the frame 1 is fixedly connected to the top plate 4, and the bottom of the top plate 4 is elastically connected to the limiting plate 11, and the top of the limiting plate 11 is fixedly connected to the bottom of the top plate 4 through several buffer plates 8. The buffer plate 8 is installed between the limiting plate 11 and the top plate 4 to play a buffering role. When the lithium battery contacts the limiting plate 11, the buffer plate 8 can absorb part of the impact force to protect the lithium battery from damage. At the same time, the buffer plate 8 also ensures a stable connection between the limiting plate 11 and the top plate 4.

[0024] Furthermore, sliders 13 are fixedly connected to both sides of the supporting frame 6, and the two sliders 13 are slidably connected to the inner wall of the frame 1 through the slide rails 14. The sliders 13 slide in the slide rails 14, thereby enhancing the stability of the supporting frame 6 during up and down movement.

[0025] Furthermore, a handle 2 is fixedly connected to one side of the frame 1 , and the connection between the output shaft of the hydraulic cylinder 5 and the frame 1 is a sliding connection, so the handle 2 is used to facilitate pushing the entire frame 1 .

[0026] Furthermore, wheels 12 are fixedly connected to the four corners of the bottom of the frame 1, and a door 3 is rotatably connected to the outer side of the frame 1 through a hinge. Specifically, opening the door 3 facilitates access to the lithium battery.

[0027] Furthermore, the top of the limit plate 11 is elastically connected to the bottom of the top plate 4 through a number of extrusion springs 9, and the bottom of the top plate 4 is fixedly connected to the top of the limit plate 11 through a number of dampers 10. Specifically, by using the damper 10 in conjunction with the extrusion spring 9, the limit plate 11 can have a certain elastic buffering effect, thereby improving the safety of the lithium battery during transportation.

[0028] Furthermore, a plurality of anti-skid plates 16 are fixedly connected to the inner side of all the bearing slots 15, and a cover plate 7 is rotatably connected to the outer side of the bearing frame 6 via a hinge. The anti-skid plates 16 in the bearing slots 15 can further improve the stability of the lithium battery.

[0029] In summary:

[0030] In actual application of the lithium battery production transfer device of the present invention, the operator needs to place the lithium batteries to be transferred in an orderly manner into the specially designed carrying groove 15 in the carrying frame 6. This design ensures that each lithium battery has a fixed position, laying the foundation for subsequent stable transfer. Then, by starting the hydraulic cylinder 5, the carrying frame 6 can be moved up smoothly. The key to this action is to enable the top of the lithium battery to gradually approach the limit. The limit plate 11 plays an important role here. Under the precise control of elastic damping, the lithium battery is properly limited. This limit not only provides necessary protection for the lithium battery, but more importantly, it effectively prevents the lithium battery from shaking during the transfer process, thereby significantly improving the safety of the transfer. In the last step, the operator only needs to push the entire frame 1 to easily complete the transfer of the lithium battery. In this process, the synergistic effect of the carrying frame 6, the limit plate 11 and its related components is particularly critical, and together they provide stable limit and comprehensive protection for the lithium battery. This design not only simplifies the operation process, but also substantially enhances the stability of the lithium battery during the transfer process, ensuring the safety and efficiency of the lithium battery. The lithium battery transport device of the present invention provides a strong guarantee for transportation. Through the clever cooperation of the carefully designed damper 10 and the extrusion spring 9, the elastic buffering function of the limit plate 11 is realized. This combination not only gives the limit plate 11 a certain flexibility, so that it can be adaptively adjusted according to the size and position of the lithium battery, but more importantly, when the lithium battery contacts the limit plate 11, the damper 10 and the extrusion spring 9 work together to effectively absorb and disperse the impact force generated. This elastic buffering effect significantly reduces the damage of the lithium battery due to collision or shaking during transportation. The risk of lithium battery being accidentally moved is reduced, thereby greatly improving the safety and reliability of lithium battery transportation. The sliders 13 are installed on both sides of the supporting frame 6 and are precisely matched with the slide rails 14 to form a stable sliding structure. When the hydraulic cylinder 5 drives the supporting frame 6 to move up and down, the sliders 13 slide smoothly along the track of the slide rails 14, effectively reducing the shaking or deviation that may occur in the supporting frame 6 during movement. When the lithium battery contacts the limit plate 11, the buffer plate 8 can absorb part of the impact force to protect the lithium battery from damage. At the same time, the buffer plate 8 also ensures a stable connection between the limit plate 11 and the top plate 4.
