Description

Technical Field

[0001] The invention belongs to the technical field of electrode sheet processing, and in particular is a laser cutting device for lithium battery electrode materials. Background Art

[0002] Lithium battery electrode sheet, referred to as electrode sheet, is an important component inside the lithium battery. It is usually made of thin aluminum or copper sheets and is used to connect the positive and negative electrode materials to achieve the functions of conduction and discharge of electricity. When producing electrode sheets, cutting is required. When cutting, the coil is usually transported by a conveyor roller. When the coil is transported, it will pass under the cutting component and the cutting work is completed by the cutting component.

[0003] A Chinese patent with announcement number CN118060920B discloses an electrode sheet cutting and polishing combined processing equipment, which cuts the electrode sheet by a cutting knife in a rotating cutting and polishing assembly, so that the cutting processing of the electrode sheet is relatively smooth, and after the cutting processing, the first polishing plate and the first sponge pad will directly grind and polish and clean the burrs on the top edge of the electrode sheet, and then cooperate with the second polishing plate and the second sponge pad to grind and polish and clean the burrs on the bottom edge of the electrode sheet, so that the cutting and polishing combined processing effect of the electrode sheet is better, and at the same time, the cutting and polishing combined processing efficiency of the electrode sheet is greatly improved, and the practicality is strong.

[0004] In the current existing technology, after the cutting component completes cutting, the conveying platform transports the cut electrode sheets to the next process. However, the existing electrode sheet cutting components, after cutting the electrode sheet roll, mostly need to manually take out the cut electrode sheets and manually place them on the conveying platform for transportation, or use mechanical settings to push all the cut electrode sheets onto the conveying platform at one time. However, this will cause the electrode sheets to be piled up in the same place. In order to avoid excessive backlog, it is necessary to wait until the conveying platform is completed before the next cutting can be carried out, so the cutting efficiency is low.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] like Figures 1 to 6As shown, a lithium battery electrode material laser cutting device described in an embodiment of the present invention comprises a workbench 1, a laser cutting assembly 2 is fixedly installed on the top of the workbench 1, a lifting seat 3 is slidably installed on the inner wall of the workbench 1, a receiving plate 4 is rotatably installed on the inner wall of the lifting seat 3, a cylinder 5 is fixedly installed on the inner wall of the workbench 1, a support frame 6 is fixedly installed on the output shaft of the cylinder 5, the top of the support frame 6 is fixedly connected to the bottom of the lifting seat 3, and a flip assembly is arranged inside the workbench 1; when cutting, the coil will be conveyed step by step from the bottom of the laser cutting assembly 2, and the laser cutting assembly 2 will cut the coil directly below, and the cut electrode sheet will fall on the top of the receiving plate 4, and after each group of electrode sheets is cut, the cylinder 5 will shrink, and when the cylinder 5 shrinks, it will drive the lifting seat 3 to move downward through the support frame 6, and when the lifting seat 3 moves downward, the receiving plate 4 will follow it. Thereby, the cut electrode sheet is driven to move to the inner side of the workbench 1, and the receiving plate 4 will contact the flipping assembly during the downward movement. The receiving plate 4 will be flipped and tilted due to the squeezing of the flipping assembly. After the receiving plate 4 is tilted, the electrode sheet located above the receiving plate 4 will slide down from above the receiving plate 4 under the action of gravity, thereby achieving the effect of automatic unloading. After the unloading work is completed, the cylinder 5 will extend to make the receiving plate 4 move up and reset, and in this process the coil will move forward to move the next cutting area to the bottom of the laser cutting assembly 2. When the receiving plate 4 is reset, the laser cutting assembly 2 performs the cutting work again. Through the above-mentioned cyclic operation, the device can automatically and timely unload and transport the cut electrode sheets after completing the cutting work of each group of electrode sheets. There is no need for manual unloading and the cut electrode sheets can be prevented from piling up, which effectively improves the working efficiency of the device.

[0024] like Figures 3 to 5 As shown, the flipping assembly includes a positioning frame 7, which is fixedly mounted on the inner wall of the workbench 1. The inner wall of the positioning frame 7 is rotatably mounted with an extrusion roller 8, and the extrusion roller 8 is located below the receiving plate 4; the receiving plate 4 is located on the inner side of the lifting seat 3 and supported by the lifting seat 3. Before the unloading work is carried out, the receiving plate 4 will always remain in a horizontal state for carrying the cut electrode sheets. The extrusion roller 8 is fixed below the receiving plate 4 through the positioning frame 7. When the lifting seat 3 and the receiving plate 4 move downward, the extrusion roller 8 will block the movement of the receiving plate 4. After being restricted by the extrusion roller 8, the receiving plate 4 will flip over on the inner side of the lifting seat 3, thereby tilting the receiving plate 4, and the cut electrode sheets will slide along the inclined surface of the receiving plate 4, thereby realizing automatic unloading.

[0025] like Figures 1 to 7As shown, a positioning seat 9 is symmetrically fixedly installed on the top of the workbench 1, and an upper pressing plate 10 is rotatably installed on the inner wall of the positioning seat 9. A lower pressing plate 35 is symmetrically fixedly installed on the top of the receiving plate 4. The two lower pressing plates 35 are respectively located below the two upper pressing plates 10. An extrusion plate 11 is fixedly installed on one end of the upper pressing plate 10 close to the positioning seat 9. A force roller 12 is rotatably installed on the inner wall of the extrusion plate 11. The outer wall of the force roller 12 is in conflict with the outer wall of the lifting seat 3. A support assembly is provided at one end of the upper pressing plate 10 away from the extrusion plate 11; in the initial state, the force roller 12 is squeezed by the lifting seat 3 to keep the upper pressing plate 10 horizontal, and the support assembly is in a retracted state at this time. When the material is unloading, the lifting seat 3 will move downward and away from the force roller 12. Since the force roller 12 is no longer squeezed by the lifting seat 3, it will The support assembly is released and thus extended. The end of the upper pressure plate 10 away from the force roller 12 will flip upward under the action of the extension of the support assembly and thus move away from the coil. When the lifting seat 3 moves up, the lifting seat 3 will squeeze the force roller 12 again. After being squeezed, the force roller 12 will drive the upper pressure plate 10 to flip in the opposite direction and approach the coil through the squeezing plate 11. At this time, the support assembly will shrink again. At the same time, when the lifting seat 3 moves up, it will drive the lower pressure plate 35 to move up. When the bottom of the lower pressure plate 35 is in contact with the coil, the upper pressure plate 10 will just be in contact with the top of the coil. Through the cooperation of the upper pressure plate 10 and the lower pressure plate 35, the coil can be clamped, thereby fixing the part of the coil to be cut, preventing the coil from shaking during the cutting work, ensuring the cutting accuracy of the device, and improving the production quality of the electrode sheet.

[0026] like Figure 7 As shown, the support assembly includes an extension plate 13, which is fixedly installed at one end of the upper pressing plate 10 away from the extrusion plate 11, and an arc-shaped telescopic rod 14 and an elastic member A15 are fixedly installed between the extension plate 13 and the workbench 1, and the two elastic members A15 are respectively sleeved on the outer wall of the arc-shaped telescopic rod 14; when the lifting seat 3 rises, the upper pressing plate 10 is forced to fit the top of the coil, and at this time the extension plate 13 will squeeze the arc-shaped telescopic rod 14 and the elastic member A15, and the arc-shaped telescopic rod 14 and the elastic member A15 will be forced to shrink, and when the lifting seat 3 descends, the elastic member A15 will extend under the action of its own elastic force, so that the extension plate 13 drives the upper pressing plate 10 to flip upward, and the flipped upper pressing plate 10 no longer contacts the coil, thereby avoiding friction between the coil and the upper pressing plate 10 when moving and being damaged, thereby ensuring the quality of subsequent electrode sheet production.

[0027] like Figures 8 to 9As shown, a piston plate 16 is slidably mounted on the inner wall of the material receiving plate 4, a plurality of elastic members B17 are fixedly mounted between the top of the piston plate 16 and the inner wall of the material receiving plate 4, an exhaust plate 18 is fixedly mounted on the inner wall of the material receiving plate 4, a plurality of exhaust holes 19 are evenly arranged on the outer wall of the exhaust plate 18, and a limiting assembly is arranged at the bottom of the material receiving plate 4; the piston plate 16 is located at the bottom of the material receiving plate 4, and in the process that the lifting seat 3 drives the material receiving plate 4 to move downward, the piston plate 16 will contact with the squeezing roller 8, so that the material receiving plate 4 is flipped under the action of the squeezing roller 8, and the limiting assembly will set a maximum flipping angle for the material receiving plate 4, and when the material receiving plate 4 rotates to the maximum flipping angle, it can no longer continue to flip, and at this time the lifting seat 3 will continue to descend, and as the lifting seat 3 continues to descend, the squeezing roller 8 will squeeze the piston plate 16, and the piston plate 16 is The extrusion will slide toward the inside of the receiving plate 4, and the elastic part B17 will shrink. When the piston plate 16 slides toward the inside of the receiving plate 4, the air inside the receiving plate 4 will be squeezed by the piston plate 16 and ejected through the exhaust hole 19 on the exhaust plate 18. The jet direction of the exhaust hole 19 is parallel to the surface of the receiving plate 4 used to place the electrode sheet. Therefore, after the air is ejected through the exhaust hole 19, it will blow the electrode sheet to move in the direction of the lower material, preventing the electrode sheet from being unable to slide due to excessive friction between the receiving plate 4 during material feeding, thereby ensuring that the electrode sheet can be effectively fed. When the lifting seat 3 moves up, the piston plate 16 will be reset under the action of the elastic part B17. It should be noted that in order to ensure that the electrode sheet can slide off the receiving plate 4, the cylinder 5 can be used to drive the lifting seat 3 to be lifted and lowered multiple times, thereby performing multiple blowing.

[0028] like Figure 6 and Figure 8 As shown, the limit assembly includes an arc-shaped slide 20, and there are two arc-shaped slides 20 which are symmetrically fixedly installed at the bottom of the receiving plate 4. The outer wall of the arc-shaped slide 20 is slidably connected to the inner wall of the lifting seat 3, and a limit block 21 is fixedly installed at one end of the arc-shaped slide 20 away from the receiving plate 4; when the receiving plate 4 is flipped, the arc-shaped slide 20 will rotate with the receiving plate 4, thereby sliding on the inner side of the lifting seat 3, and the arc-shaped slide 20 will drive the limit block 21 to move when rotating. When the limit block 21 contacts the lifting seat 3, the receiving plate 4 will be restricted and stop rotating. At this time, the receiving plate 4 rotates to the maximum angle, providing conditions for subsequent blowing work.

[0029] like Figure 1 and Figure 3 As shown, an outer wall of the workbench 1 is provided with an inclined groove, and a discharge plate 22 is fixedly installed on the inner wall of the inclined groove, and the discharge plate 22 is located obliquely below the receiving plate 4; the opening of the inclined groove enables the cut electrode sheets to be conveyed to the outside of the workbench 1, and when the receiving plate 4 is flipped over for unloading, the electrode sheets will slide along the inclined receiving plate 4 to the discharge plate 22, and then the electrode sheets will slide along the discharge plate 22 from the inner side of the workbench 1 to the conveying equipment for transportation.

[0030] like Figure 3 and Fig.10 As shown, a mounting frame 23 is fixedly installed at the bottom of the discharge plate 22, a horizontal plate 24 is fixedly installed on the inner wall of the mounting frame 23, a sliding shaft 25 is slidably installed on the inner wall of the horizontal plate 24, an elastic hammer 26 is fixedly installed on one end of the sliding shaft 25, an elastic member C27 is fixedly installed between the elastic hammer 26 and the horizontal plate 24, a force plate 28 is fixedly installed on the end of the sliding shaft 25 away from the elastic hammer 26, the force plate 28 is located above the horizontal plate 24, a limiting plate 29 is fixedly installed between the horizontal plate 24 and the discharge plate 22, the outer wall of the limiting plate 29 is slidably connected to the inner wall of the force plate 28, and a pulling component is arranged above the force plate 28; the cylinder 5 pushes the support frame When the force plate 28 moves upward, the pulling assembly will pull the force plate 28 upward. When the force plate 28 moves upward, it will pull the elastic hammer 26 upward through the sliding shaft 25. When the elastic hammer 26 moves upward, it will squeeze the elastic member C27 to shrink it. The pulling assembly will separate from the force plate 28 during the upward movement. At this time, since the force plate 28 is no longer restricted by the pulling assembly, the elastic force accumulated by the contraction of the elastic member C27 will be released, thereby pushing the elastic hammer 26 to knock the mounting frame 23. After being knocked, the mounting frame 23 will generate vibration and transmit it to the discharge plate 22. The discharge plate 22 can ensure that the electrode sheet that slides above it slides down effectively through vibration, thereby ensuring that the device can unload materials stably.

[0031] like Figure 3 and Fig.11 As shown, the pulling assembly includes a flip frame 30, which is fixedly mounted on the bottom of the support frame 6. A torsion spring shaft 31 is fixedly mounted on the inner wall of the flip frame 30, and a hook plate 32 is fixedly mounted on the outer wall of the torsion spring shaft 31. The hook plate 32 is located above the force-bearing plate 28. When the support frame 6 descends, it drives the flip frame 30 to move downward. When the flip frame 30 moves downward, it drives the hook plate 32 to move downward through the torsion spring shaft 31. During the downward movement of the hook plate 32, it will conflict with the force-bearing plate 28. Since the force-bearing plate 28 does not have the conditions to move downward, Therefore, the force-bearing plate 28 will squeeze the hook plate 32 to make it rotate around the torsion spring shaft 31, and then the hook plate 32 will pass over the force-bearing plate 28 during the downward movement. When the support frame 6 rises, the hook plate 32 will follow and rise. When the hook plate 32 rises, it will pull the force-bearing plate 28 up to cause the elastic part C27 to contract. When the elastic part C27 is compressed to the maximum value, the hook plate 32 will rotate around the torsion spring shaft 31 again and pass over the force-bearing plate 28 again. At this time, the elastic force accumulated by the contraction of the elastic part C27 will be released, thereby realizing the knocking operation.

[0032] like Figure 1As shown, the outer wall of the workbench 1 is symmetrically fixed with conveying rollers 33 and positioning rollers 34, and the two positioning rollers 34 are respectively located above the two conveying rollers 33; during the cutting process, the device realizes the conveying of the coil by the rotation of the two conveying rollers 33, and limits the coil by the two positioning rollers 34 to ensure that the coil can move along the preset direction.

[0033] Working principle: During the cutting process, the device realizes the conveying of the coil by the rotation of the two conveying rollers 33, and limits the coil by the two positioning rollers 34 to ensure that the coil can move along the preset direction. The opening of the inclined groove enables the cut electrode sheet to be conveyed to the outside of the workbench 1. When the receiving plate 4 is turned over for unloading, the electrode sheet will slide along the inclined receiving plate 4 to the discharge plate 22, and then the electrode sheet will slide along the discharge plate 22 from the inside of the workbench 1 to the conveying equipment for transportation.

[0034] When the cutting work is performed, the coil will be conveyed step by step from the bottom of the laser cutting component 2, and the laser cutting component 2 will cut the coil directly below, and the cut electrode sheet will fall on the top of the receiving plate 4. After each group of electrode sheets is cut, the cylinder 5 will contract. When the cylinder 5 contracts, it will drive the lifting seat 3 to move downward through the support frame 6. When the lifting seat 3 moves downward, the receiving plate 4 will follow the downward movement, thereby driving the cut electrode sheet to move to the inner side of the workbench 1. In the process of the receiving plate 4 moving downward, it will contact the flipping component. The receiving plate 4 will flip and tilt due to the squeezing of the flipping component. After the receiving plate 4 tilts, the electrode sheet located above the receiving plate 4 will slide from the top of the receiving plate 4 under the action of gravity, thereby achieving the effect of automatic unloading. After the unloading work is completed, the cylinder 5 will extend to make the receiving plate 4 move up and back The laser cutting assembly 2 is in position, and in this process the coil will move forward to move the next cutting area to the bottom of the laser cutting assembly 2. When the receiving plate 4 is reset, the laser cutting assembly 2 performs cutting again. Through the above-mentioned cyclic operation, the device can automatically and timely unload and transport the cut electrode sheets after completing the cutting of each group of electrode sheets. There is no need for manual unloading and the cut electrode sheets can be prevented from piling up, which effectively improves the working efficiency of the device. The squeezing roller 8 is fixed to the bottom of the receiving plate 4 by the positioning frame 7. When the lifting seat 3 and the receiving plate 4 move downward, the squeezing roller 8 will block the movement of the receiving plate 4. After being restricted by the squeezing roller 8, the receiving plate 4 will flip over on the inner side of the lifting seat 3, thereby tilting the receiving plate 4, and the cut electrode sheets will slide along the inclined surface of the receiving plate 4, thereby realizing automatic unloading.

[0035] When the lifting seat 3 moves downward, the force roller 12 is no longer squeezed by the lifting seat 3, and the upper pressure plate 10 will flip upward under the action of the supporting assembly. When the lifting seat 3 moves upward, the lifting seat 3 will squeeze the force roller 12. After being squeezed, the force roller 12 will drive the upper pressure plate 10 to flip in the opposite direction and approach the coil through the squeezing plate 11. At the same time, when the lifting seat 3 moves upward, it will drive the lower pressure plate 35 to move upward. When the bottom of the lower pressure plate 35 is in contact with the coil, the upper pressure plate 10 will just be in contact with the top of the coil. Through the cooperation of the upper pressure plate 10 and the lower pressure plate 35, the coil can be clamped, so as to fix the part of the coil to be cut, and prevent the coil from being rolled. The material shakes during the cutting process, which ensures the cutting accuracy of the device and improves the production quality of the electrode sheet. When the lifting seat 3 rises, the upper pressure plate 10 is forced to fit the top of the coil. At this time, the extension plate 13 will squeeze the arc-shaped telescopic rod 14 and the elastic member A15, and the arc-shaped telescopic rod 14 and the elastic member A15 will be forced to shrink. When the lifting seat 3 descends, the elastic member A15 will extend under the action of its own elastic force, so that the extension plate 13 drives the upper pressure plate 10 to flip upward. After the flip, the upper pressure plate 10 no longer contacts the coil, thereby avoiding friction between the coil and the upper pressure plate 10 when moving and causing damage, thereby ensuring the quality of subsequent electrode sheet production.

[0036] The piston plate 16 is located at the bottom of the material receiving plate 4. When the lifting seat 3 drives the material receiving plate 4 to move downward, the piston plate 16 will contact the squeezing roller 8, so that the material receiving plate 4 will be flipped under the action of the squeezing roller 8. The limit assembly will set a maximum flipping angle for the material receiving plate 4. When the material receiving plate 4 rotates to the maximum flipping angle, it can no longer continue to flip. At this time, the lifting seat 3 will continue to descend. As the lifting seat 3 continues to descend, the squeezing roller 8 will squeeze the piston plate 16. The piston plate 16 will slide toward the inside of the material receiving plate 4 under the squeezing, and the elastic member B17 will shrink. When the piston plate 16 slides toward the inside of the material receiving plate 4, the air inside the material receiving plate 4 will be squeezed by the piston plate 16 and ejected through the exhaust hole 19 on the exhaust plate 18. The jet direction of the exhaust hole 19 is parallel to the surface of the material receiving plate 4 for placing the electrode sheet, so the air passes through After the exhaust hole 19 sprays out, it will blow the electrode sheet to move in the direction of the lower material, preventing the electrode sheet from being unable to slide due to excessive friction between the electrode sheet and the receiving plate 4 during material feeding, thereby ensuring that the electrode sheet can be effectively fed. When the lifting seat 3 moves up, the piston plate 16 will be reset under the action of the elastic member B17. It should be noted that in order to ensure that the electrode sheet can slide off the receiving plate 4, the lifting seat 3 can be driven by the cylinder 5 to be lifted and lowered multiple times, thereby performing multiple blowing. When the receiving plate 4 is flipped, the arc-shaped slide plate 20 will rotate with the receiving plate 4, thereby sliding on the inner side of the lifting seat 3. The arc-shaped slide plate 20 will drive the limit block 21 to move when rotating. When the limit block 21 contacts the lifting seat 3, the receiving plate 4 will be restricted and stop rotating. At this time, the receiving plate 4 rotates to the maximum angle, providing conditions for subsequent blowing work.

[0037] When the cylinder 5 pushes the support frame 6 to move upward, the pulling assembly will pull the force plate 28 upward. When the force plate 28 moves upward, it will pull the elastic hammer 26 upward through the sliding shaft 25. When the elastic hammer 26 moves upward, it will squeeze the elastic part C27 to shrink it. The pulling assembly will separate from the force plate 28 during the upward movement. At this time, since the force plate 28 is no longer restricted by the pulling assembly, the elastic force accumulated by the contraction of the elastic part C27 will be released, thereby pushing the elastic hammer 26 to knock the mounting frame 23. After being knocked, the mounting frame 23 will generate vibration and transmit it to the discharge plate 22. The discharge plate 22 can ensure that the electrode sheet that slides above it slides down effectively through vibration, thereby ensuring that the device can unload materials stably. The support frame 6 will drive the flip frame when it descends. When the flip frame 30 moves downward, the hook plate 32 will be driven downward by the torsion spring shaft 31. During the downward movement of the hook plate 32, it will conflict with the force plate 28. Since the force plate 28 does not have the condition to move downward, the force plate 28 will squeeze the hook plate 32 to make it rotate around the torsion spring shaft 31, and then the hook plate 32 will pass over the force plate 28 during the downward movement. When the support frame 6 rises, the hook plate 32 will rise with it. When the hook plate 32 rises, it will pull the force plate 28 to rise and make the elastic member C27 contract. When the elastic member C27 is compressed to the maximum value, the hook plate 32 will rotate around the torsion spring shaft 31 again to pass over the force plate 28 again. At this time, the elastic force accumulated by the contraction of the elastic member C27 will be released, thereby realizing the knocking work.
