Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery slitting machines, in particular to an auxiliary unloading mechanism of a lithium battery slitting machine. Background Art

[0002] Lithium battery slitting machine is a very critical equipment in the lithium battery manufacturing process. It is mainly used to split the continuous large roll of pole piece (anode or cathode) or separator into multiple narrow strips of material according to the specified width. These materials will then be used for the assembly of battery cells. The performance of the slitting machine directly affects the size consistency, electrical performance and production efficiency of the battery.

[0003] The patent with publication number CN216836392U discloses an auxiliary unloading device for a lithium battery slitting machine. The utility model adjusts the height of the base frame by extending and retracting the cylinder to allow the supporting platform to slide up and down along the slide groove, thereby meeting the different working heights of different slitting machines, controlling the forward and reverse rotation of the drive motor, and the drive motor transmits power to the threaded rod through a pulley mechanism, so that the threaded rod rotates and pushes the two clamps to move toward or away from each other along the groove, so that it can be adjusted according to the length of different sleeves and pole piece rolls. At the same time, the supporting groove on the upper end of the clamp is supported on both sides of the sleeve to avoid scratching the coating slurry on the bottom side of the pole piece roll, thereby improving production quality.

[0004] The above scheme has the problem of insufficient stability in actual application, which is mainly reflected in that when the base frame is raised and lowered to a specified height to support the pole piece roll, due to the lack of effective auxiliary support and relying solely on the support of the cylinder, it is easy for the cylinder to be unevenly stressed due to sudden changes in load (such as weight differences of the pole piece roll), thereby increasing wear and potential mechanical damage to the cylinder. Utility Model Content

The hydraulic lifting rod 3 of this structure drives the lifting plate 4 to be lifted and lowered in the lifting frame 2 to perform precise position control on the base frame 5, and the two clamping plates 6 can adjust the spacing at the top of the base frame 5 through the guide rail to adapt to pole piece rolls of different widths, thereby ensuring the flexibility and accuracy of loading. At the same time, the lifting mechanism provided on both sides of the lifting frame 2 can drive the guide block 7 to lift the height, so that the rectangular support seat 8 drives the support column 9 to automatically adjust with the lifting of the base frame 5 to form a stable multi-point support, which effectively solves the problem of insufficient stability when the base frame 5 is lifted and lowered to support the pole piece roll. Even in the case of sudden load changes, the weight can be evenly distributed through the support column 9 to avoid the hydraulic lifting rod 3 The wear and damage caused by uneven force alone significantly enhances the stability and safety of the entire unloading mechanism, effectively improving production efficiency and product quality. An empty slot 14 is opened inside the rectangular support seat 8, and an elastic pressure pad 16 is arranged at the lower end of the empty slot 14. The elastic pressure pad 16 can be made of a material with excellent elasticity and wear resistance, such as natural rubber, synthetic rubber or silicone. A pressure plate 15 is arranged on the top surface of the elastic pressure pad 16, and the bottom ends of the support columns 9 are movable and penetrate to the inner wall of the empty slot 14 and are fixedly connected to the top of the pressure plate 15. In this structure, when the support column 9 is adjusted in height with the bottom frame 5, the support column 9 can squeeze the elastic pressure pad 16 through the pressure plate 15 after being stressed. The elastic pressure pad 16 not only ensures the support column 9 and the bottom frame through compression and rebound, but also ensures the stability of the support column 9 and the bottom frame. 5 is firmly fitted, and the necessary shock-absorbing and buffering effect is provided, which effectively absorbs vibrations during operation and protects the equipment from impact damage. The rectangular support seat 8 corresponds to the position of the side edge of the base frame 5, and the support column 9 is evenly distributed on the top of the rectangular support seat 8. The support column 9 of this structure can symmetrically and evenly support the entire base frame 5, effectively disperse the load, and avoid instability or local damage caused by concentrated stress. This not only improves the stability of the base frame 5 and the pole piece roll it carries, but also optimizes the force structure of the equipment, and reduces the risk of vibration and deviation caused by sudden load changes or uneven ground. The lifting mechanism of the outer walls on both sides of the lifting frame 2 includes a motor 10, a support block 11, a screw rod 12 and a screw block 13. The support block 11 is fixed to the upper and lower ends of the outer wall of the lifting frame 2.The motor 10 is fixedly installed on the top of the support block 11 at the upper end of the lifting frame 2 by bolts, the screw rod 12 is connected between the two support blocks 11, and the connection between the screw rod 12 and the support block 11 is connected by bearings. The screw block 13 is sleeved on the outside of the screw rod 12 through a threaded structure. The lifting frame 2 is provided with a vertically distributed through-hole 17, and one end of the screw block 13 extends to the inner side of the lifting frame 2 through the through-hole 17 and is fixedly connected to the guide block 7. The motor 10 of this structure drives the screw rod 12 to rotate and can cooperate with the thread of the screw block 13 and the screw rod 12 to realize the screw block 13 moving up and down along the screw rod 12, and the screw block 13 is then brought through the through-hole 17. The movable guide block 7 and the rectangular support seat 8 move up and down to control the lifting of the support column 9. The clamping plate 6 is composed of an upper clamping plate 61 and a lower clamping plate 62. The bottom of the upper clamping plate 61 is provided with a drawing groove that matches the upper structure of the lower clamping plate 62. The connection between the upper clamping plate 61 and the lower clamping plate 62 is connected with a fixing bolt through a threaded structure. The clamping plate 6 of this structure can be adjusted by adjusting the relative position of the upper clamping plate 61 and the lower clamping plate 62, that is, pulled to a suitable height, and locked by a fixing bolt through a threaded structure, thereby realizing flexible limiting and firm clamping of pole sheet rolls of various thicknesses, greatly enhancing the scope of application and operational convenience of the equipment.

[0019] Working principle: When using the auxiliary unloading mechanism of the lithium battery slitting machine, the hydraulic lifting rod 3 is first started. The hydraulic lifting rod 3 can drive the lifting plate 4 to rise and fall in the lifting frame 2 to drive the bottom frame 5 to perform precise position control. When the bottom frame 5 is lifted to a suitable height, the motor 10 is started. The motor 10 drives the screw rod 12 to rotate between the two support blocks 11. The screw rod 12 rotates and interacts with the thread of the screw block 13 to drive it to move up and down. Then the screw block 13 drives the guide block 7 to rise and fall on the inner side of the lifting frame 2 through the through port 17. When the guide block 7 is lifted and lowered, it passes through the rectangular support The support seat 8 supports the support column 9 on both sides of the bottom of the base frame 5. After the support column 9 is subjected to force, the elastic pressure pad 16 can be squeezed by the pressure plate 15 to ensure that the support column 9 and the base frame 5 fit firmly, and the clamping plate 6 can be pulled out and adjusted with threaded fixing bolts through the upper clamping plate 61 and the lower clamping plate 62 to flexibly match electrode rolls of different widths. During the whole process, from the base plate 1 to the lifting frame 2, the hydraulic lifting rod 3, the clamping plate 6, the support column 9 and the lifting mechanism, the precise unloading operation of the electrode roll is realized together, which improves the production efficiency and product quality, thereby completing a series of tasks.
