Technical Field
[0001] This utility model relates to the field of battery cell production technology, specifically a fully automatic slitting machine for battery cell production. Background Technology
[0002] Battery cells are divided into three types: aluminum-cased cells, pouch cells (also known as "polymer cells"), and cylindrical cells. Electrode sheets are needed during the manufacturing process of battery cells. When manufacturing electrode sheets, the electrode sheet material needs to be cut into strips of the required specifications.
[0003] In existing automatic slitting machines, when the electrode material rolls are used up, operators need to manually replace them. This replacement is quite troublesome, which reduces the efficiency of electrode sheet production slitting. The material rolls are mostly wound on a winding rod during use. When the wound material is used up, the winding rod needs to be removed from the slitting machine and installed onto the feeding structure of the slitting machine. The process of installing and removing the winding rod is quite troublesome. Utility Model Content
[0004] The purpose of this invention is to solve the problem that existing automatic slitting machines require manual replacement of used electrode material rolls after use, which is cumbersome and reduces the efficiency of electrode production slitting. Furthermore, material rolls are mostly wound on a winding rod, and after the material is used up, the winding rod needs to be removed from the slitting machine and installed onto the feeding structure, which is also cumbersome. Therefore, this invention provides a fully automatic slitting machine for battery cell production.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a fully automatic slitting machine for battery cell production, comprising a slitting machine body, a base plate located in the middle of the lower front side of the slitting machine body, a support plate slidably connected to one side of the top of the base plate, a feeding rod rotatably connected above the support plate, an adjusting disc fixedly connected to one end of the feeding rod, a toothed plate fixedly connected to one end of the upper surface of the base plate, an electric push rod fixedly connected to the middle of the bottom end of one side of the support plate, four mounting plates evenly fixedly connected to the outer side of the feeding rod, a material film roll rod located on one side of the mounting plate, an electrode material film wound around the outer side of the material film roll rod, a positioning block located at both the left and right ends of one side of the slitting machine body, a tenon fixedly located in the middle of one side of the material film roll rod, a tenon groove formed in the middle of one end of the positioning block, and the material film roll rod engaging with the positioning block via the tenon and the tenon groove.
[0006] As a further embodiment of this utility model: an arc-shaped clamp plate is rotatably connected to one side of the mounting support plate, a locking plate is fixedly connected to one side of the arc-shaped clamp plate, an insert rod is slidably connected to the outer surface of the locking plate, a push-adjustment plate is provided at one end of the insert rod, a fixing plate is provided at one end of the push-adjustment plate, the push-adjustment plate is slidably connected to the mounting support plate, and the fixing plate is fixedly connected to the surface of the mounting support plate.

[0010] As a further embodiment of this utility model: one side of the limiting block two is engaged with the limiting block one, and one end of the limiting block one is fixedly connected to the adjusting plate.
[0011] Compared with the prior art, the advantages of this utility model are: it facilitates automatic replacement of electrode material rolls, making replacement more convenient and faster, which helps to improve slitting efficiency and facilitates quick disassembly and replacement of used winding rods.
[0012] 1. The system comprises an electric push rod, support plate, feeding rotor, base plate, material film roll rod, adjusting plate, and toothed plate. The electric push rod, via the support plate, drives the feeding rotor to slide towards the front of the base plate. This causes a material film roll rod located behind the feeding rotor to slide towards the front of the base plate. When the adjusting plate slides and engages above the toothed plate, it rotates 90 degrees under the interaction of the pawl block and the toothed plate. This causes the material film roll rod on one side of the feeding rotor to rotate 90 degrees to one side, thereby driving the electrode film film wound on the upper part of the feeding rotor to rotate 90 degrees. The material film roll is rotated 90 degrees, and then the electric push rod pushes the support plate to slide towards the main body of the slitting machine. When the material film roll slides and locks onto the positioning block, the tenon fixedly connected at the middle of one end of the material film roll will lock into the tenon groove opened in the middle of the positioning block, completing the feeding process. If the positioning block rotates at this time, it will drive the material film roll locked at one end to rotate, slowly releasing the material wound on the material film roll to one side, which facilitates automatic replacement of the electrode material roll. The replacement is more convenient and faster, which helps to improve the slitting efficiency.
[0013] 2. When disassembling and replacing the used material film roll rod using the provided insert rod, push adjustment plate, locking plate, arc-shaped clamp plate, and mounting support plate, slide the insert rod to one side to allow it to slide out of the insertion hole on the push adjustment plate and the fixed plate. Then slide the push adjustment plate to one end to separate it from the locking plate. The push adjustment plate will then drive the clamp block fixedly connected to one side to slide to one side and separate it from the material film roll rod. At this time, rotate the arc-shaped clamp plate to one side to separate it from one end of the material film roll rod. Then, take the material film roll rod out from the arc-shaped groove on the surface of the mounting support plate, which facilitates the quick disassembly and replacement of the used winding rod.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figures 1-4In this embodiment of the present invention, a fully automatic slitting machine for battery cell production includes a slitting machine body 1. A base plate 7 is provided in the middle of the lower front side of the slitting machine body 1. A support plate 5 is slidably connected to one side of the top of the base plate 7. A feeding rod 4 is rotatably connected above the support plate 5. An adjusting plate 6 is fixedly connected to one end of the feeding rod 4. A toothed plate 8 is fixedly connected to one end of the upper surface of the base plate 7. An electric push rod 9 is fixedly connected to the middle of the bottom end of one side of the support plate 5. Four mounting plates 15 are evenly fixedly connected to the outer side of the feeding rod 4. A material film winding rod 17 is provided on one side of the mounting plate 15. An electrode material film 3 is wound on the outer side of the material film winding rod 17. A positioning block 2 is provided at both the left and right ends of one side of the slitting machine body 1. A tenon 11 is fixed in the middle of one side of the material film roll rod 17. A tenon groove is provided in the middle of one end of the positioning block 2. The material film roll rod 17 can be engaged with the positioning block 2 through the tenon 11 and the tenon groove. An installation ring groove 18 is provided on the outer surface of the adjusting plate 6. Multiple pawl blocks 19 are evenly arranged on the inner side of the installation ring groove 18. A spring ring 20 is provided in the middle of the upper part of one end of the pawl block 19. A second limiting column block 22 is fixedly connected to the upper part of one side of the pawl block 19. A first limiting column block 21 is engaged on one side of the second limiting column block 22. One end of the first limiting column block 21 is fixedly connected to the adjusting plate 6.
[0021] In this embodiment: when it is necessary to change the material roll, the electric push rod 9 drives the support plate 5 fixedly connected to one side to slide towards the front of the base plate 7, thereby driving the feeding rotating rod 4 provided on the top of the support plate 5 to slide towards the front of the base plate 7, thereby driving a material film roll rod 17 provided on the rear side of the feeding rotating rod 4 to slide towards the front of the base plate 7. When the adjusting plate 6 fixedly connected to one end of the feeding rotating rod 4 slides and locks above the toothed plate 8, the pawl block 19 provided on one end of the adjusting plate 6 will move accordingly. The support plate 5 slides into the toothed groove on the toothed plate 8. The pawl block 19 is fixed in place by the cooperation of the limiting post 22 and the limiting post 21. When the pawl block 19 on the adjusting plate 6, which slides to one side, contacts the toothed groove on the toothed plate 8, the toothed groove on the toothed plate 8 pushes the pawl block 19 to rotate backward, thereby causing the adjusting plate 6 connected to one end of the pawl block 19 to rotate. The rotating adjusting plate 6 will cause the feeding rod 4, which is fixedly connected to the middle of one end, to rotate. The rotating feeding rod 4 will... The material film roll 17 on one side is rotated. When the adjusting plate 6 rotates 90 degrees with the cooperation of the pawl block and the toothed plate 8, it will drive the material film roll 17 on one side of the feeding rod 4 to rotate 90 degrees to one side. This will drive the material film roll 17 with the electrode material film 3 wound on the feeding rod 4 to rotate 90 degrees. Then, the electric push rod 9 pushes the support plate 5 to slide in the direction of the slitting machine body 1. This will drive the feeding rod 4 connected to the support plate 5 to slide in the direction of the slitting machine body 1. This will cause the material film roll 17 on one side of the feeding rod 4 to slide in the direction of the slitting machine body 1. When the material film roll 17 slides and locks onto the positioning block 2, the tenon 11 fixedly connected to the middle of one end of the material film roll 17 will lock into the tenon groove opened in the middle of the positioning block 2, completing the feeding process. If the positioning block 2 rotates at this time, it will drive the material film roll 17 locked at one end to rotate and slowly release the material wound on the material film roll 17 to one side.
[0022] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 An arc-shaped clamp plate 10 is rotatably connected to one side of the mounting plate 15. A locking plate 12 is fixedly connected to one side of the arc-shaped clamp plate 10. An insert rod 13 is slidably connected to the outer surface of the locking plate 12. One end of the insert rod 13 is provided with a push-adjustment plate 14. One end of the push-adjustment plate 14 is provided with a fixing plate 16. The push-adjustment plate 14 is slidably connected to the mounting plate 15. The fixing plate 16 is fixedly connected to the surface of the mounting plate 15. Insertion holes are provided at the connection points of the insert rod 13 with the push-adjustment plate 14 and the fixing plate 16. A sliding limit plate is fixed to one end of the surface of the locking plate 12.
[0023] In this embodiment: when disassembling and replacing the material film roll rod 17 after the material has been used up, slide the insertion rod 13 to one side so that the insertion rod 13 slides out of the insertion hole opened on the push adjustment plate 14 and the fixing plate 16. Then slide the push adjustment plate 14 to one end so that the push adjustment plate 14 separates from the locking plate 12. The push adjustment plate 14 drives the clamp block fixedly connected to one side to slide to one side and separate from the material film roll rod 17. At this time, rotate the arc-shaped clamp plate 10 to one end so that the arc-shaped clamp plate 10 rotates to one side and separates from one end of the material film roll rod 17. Then take out the material film roll rod 17 from the arc-shaped groove opened on the surface of the mounting support plate 15. The two ends of the replacement material film roll rod 17 with the material roll wound on it are respectively clamped into the corresponding grooves opened on the surface of the mounting support plate 15. The material film roll rod 17 is inserted into the arc-shaped groove. Then, the arc-shaped clamp plate 10 is rotated so that it is clamped onto the surface of the material film roll rod 17. The clamping plate 12, which is fixedly connected to one side of the arc-shaped clamp plate 10, is clamped onto the surface of the mounting plate 15. Then, the push adjustment plate 14 is slid to the other side so that it is clamped onto the surface of the clamping plate 12. This causes the clamping block, which is fixedly connected below the push adjustment plate 14, to slide onto the surface of the material film roll rod 17, clamping and positioning the material film roll rod 17. The clamping plate 12 is positioned once by the push adjustment plate 14. Then, the insertion rod 13 is slid so that it is clamped into the insertion hole opened on the push adjustment plate 14 and the fixing plate 16, fixing the adjusted position of the arc-shaped clamp plate 10 and completing the replacement of the material film roll rod 17.
