Description

Technical Field

[0002] Lithium-ion batteries mainly consist of five parts: positive electrode material, negative electrode material, separator, electrolyte, and encapsulation material. Among these, the battery separator primarily functions to prevent direct contact between the positive and negative electrodes, prevent short circuits, and facilitate ion transport; it is a key material ensuring battery safety and influencing battery performance. Although the separator does not directly participate in the battery's electrochemical reactions, its performance affects the battery's interface structure, internal resistance, and other properties, thereby impacting the battery's energy density, cycle life, and rate capability.

[0003] The lithium battery separator roll slitting machine is one of the key pieces of equipment in the production process of lithium battery material separators. It works by using vertical blades to cut a roll of separator material of a certain width into several narrower strips. The final quality of the film depends not only on the quality of the film fabrication process but also on the quality of the slitting process; the slitting process is a crucial step in determining the quality of the film.

[0004] Existing slitting machines generally use manual feeding. That is, after a roll of lithium battery separator material is slitted, the worker needs to remove the empty separator roll and then install a new full separator roll on the support shaft for a new round of unwinding and slitting. This method not only increases the labor intensity of the workers, but also reduces the feeding efficiency. Therefore, it is necessary to design a feeding device for lithium battery roll slitting machines that can automatically feed separator rolls to improve feeding efficiency. Utility Model Content

A stepper motor 9 is fixed to one side of the moving block 8. A clamping plate 10 is fixed to the output end of the stepper motor 9. An abutment plate 11 is fixed to one side of the outer wall of the clamping plate 10. The abutment plate 11 is used to support the roll body 5. The connecting rod 756 is rotatably connected to the rotating component 753. The automatic feeding of the roll body 5 can be realized through the feeding mechanism 7, which effectively improves the feeding efficiency and enhances the convenience and usability of the device.

[0031] A groove 12 is provided on the lower side of the support plate 2, and a fixing plate 13 is fixedly provided on the lower side of the support plate 2. A telescopic cylinder 14 is installed on the upper surface of one side of the fixing plate 13. A movable plate 15 is installed at one end of the telescopic cylinder 14. The movable plate 15 is slidably connected to the inner wall of the groove 12. The movable plate 15 is fixedly connected to the bearing plate 3. A placement groove 16 is fixedly provided on the bearing plate 3. By setting a liftable bearing plate 3, the bearing plate 3 can be moved to the bottom when not in use. When in use, the bearing plate 3 can be raised and lowered to a suitable position by the telescopic cylinder 14, which facilitates the improvement of the placement stability of the roll body 5.

[0032] A telescopic cylinder 17 is installed on one side of the upper surface of the fixed plate 13. A support shaft 18 is fixedly connected to the output end of the telescopic cylinder 17. The outer diameter of the support shaft 18 is adapted to the inner diameter of the roll body 5. The support shaft 18 is inserted into the roll body 5. The telescopic cylinder 17 and the support shaft 18 can limit and support the unwinding stability of the roll body 5.

[0033] A protective frame 19 is fixedly mounted on one side of the fixed frame 71, and a protective plate 20 is fixedly mounted on one side of the fixed frame 71. An opening 21 is opened on one side of the protective frame 19. A baffle 22 is movably connected to the inner wall of the opening 21. A magnetic strip 23 is symmetrically fixed to the inner wall of the opening 21. A magnetic strip 24 is fixed to the two side walls of the baffle 22. The baffle 22 is installed inside the opening 21 through the magnetic strips 23 and 24. A pull handle 25 is fixed to the middle of one side of the baffle 22. An upper pressure roller 26 and a lower pressure roller 27 are provided on the inner wall of the slitting machine frame 1. A PLC control panel 28 is provided on one side wall of the support plate 2. The protective frame 19 and protective plate 20 are designed to protect the adjusting screw 73, preventing impurities from accumulating between the meshing teeth of the adjusting screw 73, thus avoiding affecting the use of the adjusting screw 73 and effectively ensuring the safety of the adjusting screw 73. The width of the opening 21 is greater than the width of the roll body 5, so pulling the handle 25 will move the baffle 22 outward in the opening 21, causing the magnetic strip 24 to disengage from the magnetic strip 23, thereby exposing the gap between the two guide plates 4, and stacking the roll body 5 from the opening 21 between the two guide plates 4. Stacking is convenient and effectively ensures the cleanliness of the surface of the roll body 5.

[0034] Working principle: When automatic feeding of the roll body 5 is required, the first step is to start the stepper motor 72 through the PLC control panel 28. The start of the stepper motor 72 drives the adjusting screw 73 to rotate. The rotation of the adjusting screw 73 drives the adjusting sleeve 74 to move, converting the rotational motion of the adjusting screw 73 into the linear motion of the adjusting sleeve 74. The movement of the adjusting sleeve 74 drives the rotating part 753 to rotate. The rotation of the rotating part 753 drives the lifting rod 755 to move on the inner wall of the guide sleeve 754 through the connecting rod 756. The movement of the lifting rod 755 drives the moving block 8 to move towards the bearing plate 3, thereby moving the stacked roll body 5 downward under the action of the abutment plate 11.

[0035] In the second step, after the bottommost roll body 5 abuts against the inner wall of the placement groove 16, stepper motor 72 is turned off, and stepper motor 9 is started via PLC control panel 28. Stepper motor 9 drives clamping plate 10 to rotate, and the rotation of clamping plate 10 causes abutment plate 11 to rotate on the outer wall of roll body 5. Although the rotation of clamping plate 10 may drive the bottommost roll body 5 to rotate circumferentially, it does not affect the rotation of abutment plate 11 from below to above roll body 5. Thus, abutment plate 11 rotates between the two roll bodies 5, lifting the upper roll body 5, so that... The bottom roll body 5 remains in the placement slot 16, and then the stepper motor 72 is driven to rotate in the opposite direction. The stacked roll bodies 5 are moved upward by the two clamping plates 10 and the abutment plate 11. The roll body 5 above the bottom roll body 5 is blocked by the guide plate 4, so when the abutment plate 11 rotates between the two roll bodies 5, the upper roll body 5 will not slip down, ensuring safety and stability. Then, the two telescopic cylinders 17 are driven by the PLC control panel 28. The two telescopic cylinders 17 drive the support shaft 18 to insert into the inner wall of the roll body 5.

[0036] The third step is for the staff to pass the battery film on the roll body 5 through the upper pressure roller 26 and the lower pressure roller 27 for conveying. The roll body 5 is unwound by an external drive mechanism.

[0037] When the roll body 5 is empty, the two telescopic cylinders 17 are activated to move the support shaft 18 away from the roll body 5. Then the empty roll body 5 can be removed from the placement groove 16 for easy unloading. Then the first and second steps are repeated to realize the automatic feeding of the roll body 5, which effectively improves the practicality and convenience of the device.

[0038] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
