Description

Technical Field

[0001] This invention relates to the field of electrode foil processing technology, specifically to a cutting device for electrode foil processing. Background Technology

[0002] In the field of aluminum electrolytic capacitor and lithium-ion battery manufacturing, electrode foil is a core basic material. The cutting process in its production aims to cut the wide master roll into specific narrow foil strips required by customers. Currently, the electrode foil cutting equipment commonly used in the industry has basic functions such as unwinding, correction, tension control, disc cutter cutting and rewinding, and has made significant progress in improving cutting efficiency and basic accuracy.

[0003] However, due to the extremely thin and soft material of the electrode foil, when using traditional upper and lower disc cutters for high-speed mechanical shearing, the combined effect of the pressure applied by the cutter and the release of internal stress in the material inevitably causes plastic deformation at the cutting edge, resulting in the foil strip edge curling to one side, commonly known as curling or folding. In the subsequent winding process, this curling defect, the hard curling edge, will scratch the adjacent foil layer like a blade, damage the insulating oxide film, and cause the capacitor leakage current to increase or even short circuit. Meanwhile, existing cutting equipment can only slide the cut electrode foil onto the platform when processing the slit electrode foil. Since the electrode foil has a certain degree of flexibility, this placement method may cause the position of each electrode foil to be inconsistent and it is easy to slide left and right. This not only affects the collection and sorting of subsequent processes, but may also cause wrinkles or scratches on the surface of the electrode foil, further reducing product quality. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a cutting device for electrode foil processing. The main purpose is to solve the problem that the combined effect of the pressure applied by the cutting tool and the release of internal stress in the material inevitably causes plastic deformation at the cutting edge, resulting in the foil strip edge curling to one side and being prone to left and right sliding.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A cutting device for electrode foil processing includes a pneumatic cutting machine, wherein a guide roller is provided on the feeding side of the pneumatic cutting machine, a base is provided on the side of the pneumatic cutting machine away from the guide roller, and a flattening assembly is provided on the top of the base near the side of the pneumatic cutting machine. The rolling assembly includes two straight plates fixedly connected to the upper surface of the base. Two connecting shafts distributed vertically are rotatably mounted between the two straight plates via bearings. One end of each connecting shaft passes through one of the straight plates and is keyed to an upper gear and a lower gear, respectively. The upper gear and the lower gear mesh with each other. A drive motor is provided on the top of the base. The output shaft of the drive motor is fixed to one of the connecting shafts via a coupling. Heating rollers are provided on the outer circumference of both connecting shafts. One end of the heating roller passes through the other straight plate and is provided with a rotary joint. The top of the base is provided with a positioning component for restricting the cut electrode foil, and the upper surface of the base away from the pneumatic cutter is provided with a baffle that cooperates with the positioning component.

[0006] Furthermore, two inclined plates are provided between the two straight plates to form an "eight" shape, and the two inclined plates are located on both sides of the two connecting shafts.

[0007] Based on the aforementioned solution, the positioning component includes two sets of first slots symmetrically arranged on the top of the base. Each set of first slots includes at least two parallel strip holes. Each strip hole has a first slide rail on both sides. The first slide rails are located on the inner top wall of the base. Two connecting plates are slidably installed between the first slide rails via a slide table. Two vertical plates are fixedly connected to the top of each connecting plate. A clamping plate is welded to the top of the two vertical plates on the same connecting plate. The clamping plate is located above the base. A servo motor is provided on one side of the base. The output shaft of the servo motor is keyed to a bidirectional lead screw. The bidirectional lead screw passes through the two connecting plates and is rotatably connected to one side of the base via a bearing.

[0008] As a further embodiment of the present invention, the width of the first slot is greater than the width of the vertical plate, and the bottom of the clamping plate does not contact the upper surface of the base.

[0009] Furthermore, pressure rollers are provided on the opposite sides of the two clamping plates, and the pressure rollers are in contact with the upper surface of the base.

[0010] Based on the aforementioned scheme, a base plate is fixedly connected inside the base. Two second slots are opened on the upper surface of the base plate, which are adapted to the first slot. A ball screw module is provided on the top of the base plate. A connecting block is fixedly connected between two slides in the ball screw module. A cylinder is provided on the top of the connecting block. A U-shaped plate is fixedly connected to the top of the connecting block. Two grooves are opened on the top of the U-shaped plate. A U-shaped frame fixed to the actuating end of the cylinder is slidably connected in the grooves. Two flat grooves are opened on the top of the base, which cooperate with the two extended ends of the U-shaped frame.

[0011] As a further embodiment of the present invention, a guide plate is fixedly connected to one end of each of the two clamping plates.

[0012] Furthermore, one end of the base is provided with two insertion holes, and the bottom of the baffle is provided with two insertion posts that mate with the insertion holes.

[0013] Compared with the prior art, the present invention provides a cutting device for electrode foil processing, which has the following advantages: 1. This invention integrates a rolling and flattening component with heating function, which realizes online heating and rolling pressing and stress elimination of the cut electrode foil. This solves the technical problem of foil edge curling and residual internal stress caused by pure mechanical shearing in traditional cutting processes, which in turn affects the flatness and product quality of subsequent processes.

[0014] 2. This invention achieves high-precision lateral alignment and longitudinal positioning of electrode foils in single pieces and stacks through a positioning component, solving the technical problem that the foils are prone to shifting and misaligning during transmission and stacking after cutting, resulting in incomplete collection and affecting automated connection.

[0015] 3. By setting a pressure roller on one side of the clamping plate that contacts the upper surface of the base, the present invention realizes the conversion of sliding friction to rolling friction when the clamping plate moves, and solves the technical problems of large wear, uneven operation, easy loss of accuracy and possible contamination of foil caused by direct scraping between the clamping plate and the working platform.

[0016] 4. By setting a Y-shaped inlet structure with a guide plate, the present invention achieves adaptive centering and smooth introduction of the electrode foil when it enters the positioning area, thus solving the technical problem that the foil may get stuck, wrinkled or damaged by edge collision due to initial position deviation.

[0017] 5. This invention integrates an automatic ejection and unloading mechanism consisting of a ball screw module, a cylinder, a U-shaped frame, and a detachable baffle, which realizes the slow and stable overall transfer and automatic unloading of the neatly stacked electrode foil, solving the problems of low efficiency and easy disruption of the stacking order when manually picking up materials.

Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0025] Please see Figures 1-8 As shown, a cutting device for electrode foil processing includes a pneumatic cutter 2. A guide roller 1 is provided on the feeding side of the pneumatic cutter 2. A base 3 is provided on the side of the pneumatic cutter 2 away from the guide roller 1. A flattening assembly 5 is provided on the top of the side of the base 3 close to the pneumatic cutter 2. An unwinding machine for rolling the electrode foil up and down is provided on one side of the guide roller 1. The electrode foil is continuously fed into the pneumatic cutter 2 through the guide roller 1. The pneumatic cutter 2 is used to cut the electrode foil. When the pneumatic cutter 2 is started, the internal cutting blade will move back and forth quickly under the air pressure drive, thereby accurately cutting the electrode foil that has been conveyed to the cutting area by the guide roller 1. After the electrode foil is cut, it will be conveyed to the flattening assembly 5 on the top of the base 3. It should be noted that the pneumatic cutting machine 2 is existing technology. The pneumatic cutting machine system mainly consists of three parts: first, the power source and delivery system, including an air compressor, air tank, air pipes, and key pneumatic triplet, which are responsible for providing clean, stable, and lubricated compressed air; second, the cutting tool body, common types of which include pneumatic saber saws that utilize reciprocating motion, high-speed rotating pneumatic angle grinders or circular saws, and pneumatic shears for sheet metal, the core of which is an internal pneumatic motor that converts air pressure into mechanical energy; and third, accessories and consumables, such as various saw blades, cutting discs, blades, guide rulers, guards, etc. Those skilled in the art can set them according to actual needs, which will not be elaborated here.

[0026] The top of the base 3 is provided with a rolling assembly 5. The rolling assembly 5 includes two straight plates 501 fixed to the upper surface of the base 3 by bolts. Two connecting shafts 506 distributed vertically are rotatably mounted between the two straight plates 501 by bearings. One end of each connecting shaft 506 passes through one of the straight plates 501 and is keyed to an upper gear 503 and a lower gear 504 respectively. The upper gear 503 and the lower gear 504 mesh with each other. The top of the base 3 is provided with a drive motor 505. The output shaft of the drive motor 505 is fixed to one of the connecting shafts 506 by a coupling. Heating rollers 502 are provided on the outer circumference of both connecting shafts 506. One end of the heating roller 502 passes through the other straight plate 501 and is provided with a rotary joint. Specifically, when the cut electrode foil enters the winding assembly 5, the drive motor 505 starts and drives the connecting shaft 506 connected to it to rotate. Since the upper gear 503 and the lower gear 504 mesh with each other, the two connecting shafts 506 will rotate synchronously in opposite directions, thereby causing the upper and lower distributed heating rollers 502 to rotate in opposite directions. Heating wires can be connected to the inside of the heating rollers 502 through a rotary joint. When the electrode foil passes between the two heating rollers 502, the temperature of the heating rollers 502 can be used to heat and soften the electrode foil, eliminating the internal stress generated during the cutting process. At the same time, the pressing action of the two heating rollers 502 can flatten the electrode foil, ensuring that the electrode foil remains flat during subsequent processing or winding, and avoiding wrinkles that affect product quality.

[0027] Between the two straight plates 501, there are two inclined plates 6 that cooperate to form an "eight" shape. The two inclined plates 6 are located on both sides of the two connecting shafts 506. After the electrode foil is cut, the cut electrode foil is transferred through one of the inclined plates 6 to the space between the two heating rollers 502 by the guide roller 1. The other inclined plate 6 is used to receive the electrode foil after it has been processed by the heating roller 502 and to guide the electrode foil to the space between the two clamping plates 806. The inclined plate 6 has a smooth surface and a certain inclination angle, which can stabilize the direction of the electrode foil transfer and prevent the electrode foil from deviating or getting stuck when entering or leaving the heating roller 502 area. The two ends of the inclined plate 6 are also provided with arc-shaped transition edges, which can further reduce the stress concentration generated when the edge of the electrode foil contacts the inclined plate 6 and prevent the edge of the electrode foil from curling or breaking. This provides a reliable guarantee for the electrode foil to enter the heating roller 502 smoothly and be subsequently transferred to the space between the clamping plates 806.

[0028] The heating roller 502 is existing technology and includes a metal roller shell, a built-in heating element, a rotary joint, a temperature sensor embedded in the roller, an external temperature controller, a drive device, and safety protection components, which together ensure that the roller surface temperature is uniform, stable, and controllable. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0029] To address the technical problem of electrode foil shifting on the base 3 after cutting, a positioning component 8 is provided on the top of the base 3 to restrict the cut electrode foil. The positioning component 8 includes two sets of first slots 7 symmetrically arranged on the top of the base 3. Each set of first slots 7 includes at least two parallel strip holes. Four first slide rails 803 are fixed inside the base 3 by bolts. Two connecting plates 802 are slidably installed between the first slide rails 803 via a slide table. Two vertical plates 805 are fixed to the top of the connecting plates 802 by bolts. Clamping plates 806 that cooperate with the first slots 7 are welded to the top of the two vertical plates 805 on the same connecting plate 802. A servo motor 804 is provided on one side of the base 3. The output shaft of the servo motor 804 is keyed to a bidirectional lead screw 801. The bidirectional lead screw 801 passes through the two connecting plates 802 and is rotatably connected to one side of the base 3 via a bearing. Specifically, when the servo motor 804 is started, the output shaft of the servo motor 804 drives the bidirectional lead screw 801 to rotate. Since the bidirectional lead screw 801 is threadedly connected to the threaded cylinders inside the two connecting plates 802, and the two connecting plates 802 are respectively located in the forward thread section and the reverse thread section of the bidirectional lead screw 801, the rotation of the bidirectional lead screw 801 will drive the two connecting plates 802 to move towards or away from each other along the first slide rail 803, thereby driving the vertical plate 805 and the clamping plate 806 to move synchronously. By adjusting the distance between the two clamping plates 806, the clamping plate 806 can be adapted to electrode foils of different widths. When the electrode foil is guided by the inclined plate 6 to the space between the two clamping plates 806, the clamping plates 806 can limit the electrode foil from both sides, effectively preventing the electrode foil from shifting laterally due to external interference or uneven tension during transmission on the base 3. At the same time, the clamping surface of the clamping plate 806 is made of wear-resistant rubber, which can increase the friction between the electrode foil and prevent the electrode foil from slipping in the clamping area, and also avoid hard extrusion damage to the surface of the electrode foil. One end of each of the two clamping plates 806 is fixed with a guide plate 807 by bolts. The two clamping plates 806 and the guide plate 807 form a Y-shaped structure, which can provide a stable guide for the edge of the electrode foil. When the electrode foil moves on the upper surface of the base 3, the two sides of the edge will contact the inner side of the two guide plates 807 respectively. Under the guidance of the guide plate 807, the electrode foil can maintain the preset movement trajectory, effectively avoiding the problem of electrode foil wrinkling or stacking caused by position displacement, and ensuring that the electrode foil can slide smoothly towards the baffle 18.

[0030] Furthermore, the first slot 7 provides space for the vertical movement of the clamping plate 806. The width of the first slot 7 is greater than the width of the vertical plate 805, and the bottom of the clamping plate 806 does not contact the upper surface of the base 3. When the vertical plate 805 moves the clamping plate 806 laterally with the connecting plate 802, it is not obstructed by the base 3, ensuring the smoothness of the adjustment process. At the same time, the gap between the clamping plate 806 and the upper surface of the base 3 can prevent friction and wear between the two during relative movement, extend the service life of the components, and prevent debris generated by friction from polluting the electrode foil transmission environment.

[0031] Meanwhile, a pressure roller 10 is provided on one side of the clamping plate 806, and the pressure roller 10 contacts the upper surface of the base 3, which avoids direct hard scraping between the metal parts of the clamping plate 806 and the upper surface of the base 3, effectively protecting the precision work platform surface and preventing it from being scratched or worn, thereby maintaining the flatness of the platform and the accuracy of the positioning reference for a long time, and extending the service life of key components of the equipment.

[0032] To facilitate the removal of the cut electrode foil, a base plate 4 is bolted to the inside of the base 3. The upper surface of the base plate 4 has two second slots 9 that match the first slot 7. A ball screw module 11 is provided on the top of the base plate 4. A connecting block 12 is bolted between two slides in the ball screw module 11. A cylinder 13 is provided on the top of the connecting block 12. A U-shaped plate 15 is bolted to the top of the connecting block 12. Two grooves 16 are provided on the top of the U-shaped plate 15. A U-shaped frame 14 that is fixed to the actuating end of the cylinder 13 is slidably connected in the grooves 16. Two flat grooves 17 that mate with the two extended ends of the U-shaped frame 14 are provided on the top of the base 3. Specifically, the initial state of the U-shaped frame 14 is that the extended end is located in the flat groove 17 and the bottom is flush with the upper surface of the base 3, and the length of the electrode foil does not exceed the U-shaped frame 14. When the cut electrode foil needs to be removed, the ball screw module 11 is activated, driving the connecting block 12 to move along the length direction of the base plate 4, thereby causing the cylinder 13 and the U-shaped plate 15 to move synchronously to below the electrode foil cutting position. Then, the actuator end of the cylinder 13 extends upward, pushing the U-shaped frame 14 to slide upward in the groove 16 of the U-shaped plate 15. After the two extended ends of the U-shaped frame 14 pass through the flat groove 17 at the top of the base 3, one end of the U-shaped frame 14 contacts the electrode foil. Then, the ball screw module 11 is activated again, moving the U-shaped frame 14 and causing the U-shaped frame 14 to push the cut electrode foil to slide along the upper surface of the base 3 towards the baffle 18.

[0033] It should be noted that the ball screw module 11 is existing technology, including motor, screw, ball slider, etc. Its structure and principle are common knowledge known to those skilled in the art, and will not be elaborated on here.

[0034] A baffle 18 is provided at one end of the upper surface of the base 3 to cooperate with the positioning component 8. Two insertion holes 20 are provided at one end of the base 3. Two insertion posts 19 are provided at the bottom of the baffle 18 to cooperate with the insertion holes 20. The baffle 18 can form a U-shaped structure with the two clamping plates 806 to limit one end of the electrode foil. Together with the two clamping plates 806, the electrode foil is limited on three sides, which effectively prevents the electrode foil from shifting or shaking during movement. This ensures that the electrode foil can slide stably in the specified direction during the cutting operation. When the electrode foil is pushed by the U-shaped frame 14 to contact the baffle 18, the baffle 18 blocks the electrode foil, so that the electrode foil stops accurately in the preset position, which is convenient for subsequent collection or further processing of the cut electrode foil. When it is necessary to collect the cut electrode foil, pull out the two pins 19 at the bottom of the baffle 18 from the socket 20, and then remove the baffle 18 from the base 3. At this time, the end of the base 3 near the inclined plate 6 forms an open structure. Under the continuous push of the U-shaped frame 14, the cut electrode foil will continue to slide along the upper surface of the base 3 until one end contacts the top of the inclined plate 6. Then, under its own gravity and the pushing action of the subsequent electrode foil, the electrode foil will slide down the inclined surface of the inclined plate 6 and finally fall into the preset collection frame below the inclined plate 6, completing the automatic collection process of the electrode foil.

[0035] The present invention is used in the following steps: S1: The rolled electrode foil master roll is loaded onto the unwinding machine. The electrode foil is smoothly and continuously conveyed to the cutting area of ​​the pneumatic cutting machine 2 by the guide roller 1. The pneumatic cutting machine 2 is started, and the internal cutting blades reciprocate at high speed under air pressure to precisely cut the continuously passing electrode foil to a fixed length or shape to obtain a single piece of electrode foil. S2: The cut single electrode foil is driven by the conveying mechanism and slides into the rolling assembly 5 along the inclined surface of the first inclined plate 6. The drive motor 505 starts and drives the upper and lower heating rollers 502 to rotate synchronously in opposite directions through the upper gear 503 and the lower gear 504. The electrode foil passes between the two rollers. On the one hand, it is uniformly heated by the heating rollers 502, which softens the electrode foil and releases the internal stress of cutting. On the other hand, it is squeezed by the pressure between the rollers and is effectively flattened, thereby eliminating defects such as curling and warping. The processed electrode foil is smoothly discharged through the inclined plate 6 on the other side. S3: The leveled electrode foil is naturally guided into the channel between the two clamping plates 806 through the Y-shaped entrance formed by the two guide plates 807. The servo motor 804 drives the bidirectional lead screw 801, which drives the two connecting plates 802 and the clamping plates 806 to move towards each other along the first slide rail 803. The electrode foil is gently clamped from both sides to perform lateral positioning and straightening. At the same time, the electrode foil continues to move forward under the action of the conveying force until the front end contacts the vertically installed baffle 18 to complete the longitudinal positioning. Through the cooperation of the clamping plates 806 and the baffle 18, the U-shaped three-sided limit of the electrode foil is realized to ensure that the electrode foil is accurately positioned and flat. S4: After positioning, the two clamps 806 maintain the channel state, and the subsequent electrode foils are pushed to stack closely against the previous electrode foil, ensuring that each electrode foil is flattened, positioned and neatly stacked on the working plane of the base 3, within the coverage area of ​​the U-shaped frame 14. S5: When the stacked electrode foils reach a predetermined number, the ball screw module 11 is activated, driving the U-shaped frame 14 to move to the rear end of the stacked foils. Then the cylinder 13 is activated, driving the extended end of the U-shaped frame 14 through the flat groove 17 to rise to a position slightly higher than the plane of the base 3. S6: At this time, the operator pulls the insert 19 of the baffle 18 out of the socket 20 and removes the baffle 18. At this time, one end of the base 3 corresponding to the inclined plate 6 is open, the ball screw module 11 is started again, and the U-shaped frame 14 is driven to push the neatly stacked electrode foils forward, so that the electrode foils slide out from the open end and slide into the preset collection box or conveyor belt below, realizing automatic and non-destructive unloading.

[0036] It should be noted that both the servo motor 804 and the drive motor 505 are used in conjunction with an encoder. The number of rotations and the rotation angle of the motor output shaft are controllable and highly accurate. The cylinder 13 in this application is a power actuator that converts the pressure energy of compressed air into mechanical energy. It can be connected to an external air pipe and a solenoid valve and drive the piston to perform linear reciprocating motion by controlling the gas in and out. It can achieve precise control of the extension and retraction displacement of the piston rod of the cylinder 13 by cooperating with a magnetic switch, a proximity switch or a photoelectric switch.

[0037] The inner wall of the threaded cylinder is provided with an annular groove, in which a nylon 66 damping ring with a Shore hardness of 85A is embedded. The continuous axial clamping force generated by its elastic deformation forms a helical angle interference fit with the surface of the double-acting screw 801 at 15°-20°. When the threaded pair is subjected to axial vibration load, the nylon insert can generate a maximum elastic compression of 0.3mm, which increases the friction coefficient between the thread contact surfaces from 0.15 to 0.68 (tested according to ASTM D1894 standard), effectively suppressing loosening displacement caused by thread springback.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
