Technical Field

[0001] The present invention relates to the technical field of copper foil cutting, and particularly to a copper foil cutting and curling device. Background Art

[0002] In the manufacturing production of copper foil wicks, due to its good electrical conductivity, thermal conductivity, ductility and other characteristics, copper foil is usually used as the main material, and through a series of processing procedures to form a wick with a specific shape and performance to meet the application requirements of different fields.

[0003] In the traditional manufacturing process of copper foil wicks, processing procedures such as slitting, curling, rounding and cutting of copper foil are usually carried out separately on different machines. The traditional way of production on separate machines requires a large amount of time and labor costs for material transfer and connection between each machine, resulting in cumbersome procedures and reducing production efficiency. Secondly, due to the operation on separate machines, more process waste is inevitably generated during the process conversion, causing waste of raw materials and increasing production costs. Summary of the Invention

[0007] Preferably, the rounding component includes a pre-rounding roller, on which pre-rounding grooves are formed along its circumferential direction. A plurality of the pre-rounding grooves are arranged at intervals along the axial direction of the pre-rounding roller. In the direction from the groove opening to the groove bottom of the pre-rounding groove, the width of the pre-rounding groove gradually decreases. The width of the groove opening is equal to the width of the strip-shaped copper foil to be processed, and the width of the groove bottom is equal to the width of the cylindrical copper foil to be processed. The pre-rounding roller can rotate around its own axis, so that the copper foil to be processed passes through the pre-rounding groove.

[0008] Preferably, the rounding component further includes a full-rounding die, on which a plurality of cylindrical full-rounding channels are formed through. One end of the full-rounding channel communicates with the pre-rounding roller, and the other end communicates with the cutting component. The copper foil to be processed passing through the pre-rounding groove can pass through the full-rounding channel.

[0009] Preferably, the conveying component includes a first pinch roller, which is arranged between the slitting component and the rounding component. The first pinch roller includes two roller bodies arranged oppositely, and a pinch gap is formed between the two roller bodies. The roller bodies can rotate around their own axes, so that the copper foil to be processed moves linearly through the pinch gap.

[0010] Preferably, the conveying component further includes a first guiding roller, which is arranged between the first pinch roller and the rounding component. The first guiding roller can rotate around its own axis, so as to convey the copper foil to be processed.

[0011] Preferably, the conveying component includes a second pinch roller, which is arranged between the rounding component and the cutting component. On the outer circumference of the second pinch roller, shaping protrusions are arranged along its circumferential direction. A plurality of the shaping protrusions are arranged at intervals along its axial direction. The shaping protrusions can be inserted into the openings of the copper foil to be processed. The second pinch roller can rotate around its own axis, so that the copper foil to be processed moves linearly.

[0012] Preferably, the copper foil cutting and rounding device further includes a winding component, which includes a winding roller. The copper foil to be processed can be wound around the outer circumference of the winding roller around the axis of the winding roller. The conveying component can convey the copper foil to be processed wound on the winding roller to the slitting component.

[0013] Preferably, the conveying component includes a second guiding roller, which is arranged between the winding component and the slitting component. The second guiding roller can rotate around its own axis, so as to convey the copper foil to be processed.

[0014] Preferably, the copper foil cutting and curling device further includes a collection box, which is connected to the cutting assembly, and the copper foil to be processed after being cut by the cutting assembly can fall into the collection box.

[0015] Advantages of the present invention: For the copper foil cutting and curling device provided by the present invention, the slitting assembly can accurately cut the whole sheet of the copper foil to be processed into multiple strips with uniform widths, which not only ensures the consistency of the slitting size, but also provides copper foil strips with unified specifications for the subsequent curling process. The curling assembly can accurately bend the strip-shaped copper foil to be processed into a cylindrical shape with an opening, ensuring that the curvature and diameter of the curling meet the requirements. The cutting assembly can accurately cut along the radial direction of the cylindrical copper foil to be processed and cut it into multiple segments. The conveying assembly stably and orderly conveys the copper foil to be processed between the slitting assembly, the curling assembly and the cutting assembly, ensuring seamless connection between each process and improving production efficiency.

[0016] By setting an integrated slitting assembly, curling assembly, cutting assembly and conveying assembly, the continuous processing of the copper foil to be processed from the whole sheet to multiple strips, then to a cylindrical shape, and finally cut into multiple segments is realized, avoiding the cumbersome problems of traditional production on separate machines, improving production efficiency, saving production time and labor costs. Secondly, since each process is continuously completed in the same device, the material transfer link between machines is reduced, thereby reducing the generation of process waste, realizing the efficient utilization of raw materials, and reducing production costs.

[0022] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0023] See Figures 1 to 10 , the copper foil cutting and curling device provided by the embodiment of the present invention includes a slitting assembly 1, a curling assembly 2, a cutting assembly 3, and a conveying assembly 4. Among them, the slitting assembly 1 is used to cut the to-be-processed copper foil 100 from a sheet-like whole into multiple strips; the curling assembly 2 is used to bend the strip-shaped to-be-processed copper foil 100 to form a cylindrical shape with an opening 101; the cutting assembly 3 is used to cut the cylindrical to-be-processed copper foil 100 along its own radial direction into multiple segments; the conveying assembly 4 is used to convey the to-be-processed copper foil 100 in sequence between the slitting assembly 1, the curling assembly 2, and the cutting assembly 3.

[0024] For the copper foil cutting and curling device proposed by the present invention, the slitting assembly 1 can accurately cut the sheet-like whole of the to-be-processed copper foil 100 into multiple strips with uniform widths, which not only ensures the consistency of the slitting size but also provides strip-shaped to-be-processed copper foils 100 with unified specifications for the subsequent curling process. The curling assembly 2 can accurately bend the strip-shaped to-be-processed copper foil 100 to form a cylindrical shape with an opening 101, ensuring that the curvature and diameter of the curling meet the requirements. The cutting assembly 3 can accurately cut along the radial direction of the cylindrical to-be-processed copper foil 100 and cut it into multiple segments. The conveying assembly 4 stably and orderly conveys the to-be-processed copper foil 100 between the slitting assembly 1, the curling assembly 2, and the cutting assembly 3, ensuring seamless connection between each process and improving production efficiency.

[0025] By setting up an integrated slitting assembly 1, curling assembly 2, cutting assembly 3, and conveying assembly 4, the coherent processing of the to-be-processed copper foil 100 from a sheet-like whole to multiple strips, then to a cylindrical shape, and finally cut into multiple segments is realized, avoiding the cumbersome problems of traditional production on separate machines, improving production efficiency, and saving production time and labor costs. Secondly, since each process is continuously completed in the same device, the material transfer link between machines is reduced, thereby reducing the generation of process waste, realizing the efficient utilization of raw materials, and reducing production costs.

[0026] The specific structure of the copper foil cutting and curling device will be described below.

[0027] See Figure 1 and Figure 2 , the copper foil cutting and curling device includes a main body table 200, and the slitting assembly 1, curling assembly 2, and cutting assembly 3 are sequentially arranged on the main body table 200 in order to facilitate the to-be-processed copper foil 100 to perform different processes in sequence.

[0028] The copper foil cutting and coiling device further includes a coiling assembly 5, which is also arranged on the main body machine 200 and is located in front of the slitting assembly 1. The coiling assembly 5 includes a coiling roller 51, and the copper foil 100 to be processed can be coiled around the outer circumference of the coiling roller 51 along the axis of the coiling roller 51. The conveying assembly 4 can convey the copper foil 100 to be processed coiled on the coiling roller 51 to the slitting assembly 1. The setting of the coiling roller 51 enables the copper foil 100 to be processed to be coiled orderly, avoiding problems such as chaotic placement, possible creases and damages of the copper foil 100 to be processed before processing, and ensuring the initial quality of the copper foil 100 to be processed. By coiling with the coiling roller 51, the storage space is effectively saved, the layout of the whole device is made more compact, and the space utilization efficiency is improved. Specifically, the coiling roller 51 is installed on the coiling bracket of the main body machine 200 through high-precision bearings to ensure its smooth and flexible rotation. At one end of the coiling roller 51, a servo motor 52 is installed. The servo motor 52 is connected to the coiling roller 51 through a synchronous belt to provide stable rotational power for the coiling roller 51. The rotation speed of the servo motor 52 can be adjusted according to production requirements through the PLC (Programmable Logic Controller) control system to achieve different coiling speeds.

[0029] During the coiling process, in order to ensure that the copper foil 100 to be processed can be coiled tightly and neatly on the coiling roller 51, adjustable limit baffles 53 are arranged on both sides of the coiling roller 51. The limit baffles 53 can be flexibly adjusted according to the width of the copper foil 100 to be processed to ensure that the copper foil 100 to be processed does not shift during the coiling process.

[0030] In addition, in order to monitor the coiling progress and status in real time, a tension sensor and a position sensor are installed near the coiling roller 51. The tension sensor can detect the tension magnitude of the copper foil 100 to be processed during the coiling process. When the tension is too large or too small, the PLC system will automatically adjust the rotation speed of the coiling roller 51 to ensure the coiling quality of the copper foil 100 to be processed. The position sensor is used to monitor the coiling position of the copper foil 100 to be processed on the coiling roller 51. When the preset coiling length is reached, a signal will be sent to stop coiling and notify the conveying assembly 4 to convey the copper foil 100 to be processed to the slitting assembly 1 for subsequent processing.

[0031] The conveying assembly 4 includes a second guide roller 44. The second guide roller 44 is arranged between the coiling assembly 5 and the slitting assembly 1. The second guide roller 44 can rotate around its own axis to convey the copper foil 100 to be processed to the slitting assembly 1.

[0032] The slitting assembly 1 is used to cut the copper foil 100 to be processed from a sheet as a whole into multiple strips. In this embodiment, the slitting assembly 1 selects an existing laser cutting machine, and its working principle and specific structure will not be elaborated here.

[0033] The laser cutting machine uses a 355nm cold light source ultraviolet light as the light source, with a pulse width of 150fs to 15ps, and uses nitrogen protection to minimize heat diffusion and oxidation. The slit width is ≤0.02mm, and the cutting accuracy is ±0.02mm.

[0034] After the strip component 1 is cut, the conveyor component 4 conveys multiple copper foils 100 to be processed to the coiling component 2. Specifically, the conveyor component 4 includes a first pinch roller 41, which is arranged between the strip component 1 and the coiling component 2. The first pinch roller 41 includes two roller bodies arranged oppositely, and a pinch gap is formed between the two roller bodies. The roller bodies can rotate around their own axes, and under the action of friction, the copper foils 100 to be processed are made to move linearly through the pinch gap.

[0035] It can be understood that the control principle of the conveyor component 4 is the same as that of the winding component 5, and will not be elaborated here.

[0036] In this embodiment, a first pinch roller 41 is also arranged between the winding component 5 and the strip component 1 to facilitate the smooth conveyance of the copper foils 100 to be processed wound on the winding roller 51 to the strip component 1.

[0037] Furthermore, the conveyor component 4 further includes a first guide roller 42, which is arranged between the first pinch roller 41 and the coiling component 2. The first guide roller 42 can rotate around its own axis to convey the copper foils 100 to be processed, thereby further guiding the conveyance direction of the copper foils 100 to be processed and enabling them to enter the coiling component 2 more accurately. Effectively reducing the inaccuracy of the position of the copper foils 100 to be processed caused by the deviation of the conveyance path, thereby improving the accuracy and quality of the coiling process.

[0038] To further improve production efficiency, two coiling components 2 and two cutting components 3 are provided respectively. The strip-shaped copper foils 100 to be processed after being cut by the strip component 1 are divided into two groups, and each group of strip-shaped copper foils 100 corresponds to a coiling component 2 and a cutting component 3. The two groups work simultaneously, enabling more copper foils 100 to be processed per unit time, thereby shortening the overall production cycle. This dual-group configuration increases the flexibility of production. When one of the coiling components 2 or cutting components 3 fails or needs maintenance, the other group can still continue to work, preventing the entire production line from coming to a complete standstill and reducing production losses caused by equipment failures. In addition, the dual-group configuration is conducive to balancing the workload of each component, avoiding increased wear and shortened lifespan caused by long-term high-load operation of a single component, thereby reducing the equipment maintenance cost and replacement frequency.

[0039] See Figure 3 and Figure 4, the curling component 2 includes a pre-curling roller 21. Along the circumferential direction of the pre-curling roller 21, pre-curling grooves 211 are provided. A plurality of pre-curling grooves 211 are arranged at intervals along the axial direction of the pre-curling roller 21. In the direction from the groove opening 2111 to the groove bottom 2112 of the pre-curling groove 211, the width of the pre-curling groove 211 gradually decreases. The width of the groove opening 2111 is equal to the width of the strip-shaped copper foil 100 to be processed, and the width of the groove bottom 2112 is equal to the width of the cylindrical copper foil 100 to be processed. The pre-curling roller 21 can rotate around its own axis, so that the copper foil 100 to be processed passes through the pre-curling groove 211. Since the width of the pre-curling groove 211 is smaller than the width of the strip-shaped copper foil 100 to be processed, when the copper foil 100 to be processed passes through the pre-curling groove 211, both sides of the copper foil 100 to be processed will be subjected to certain extrusion and constraint. Coupled with the tension provided by the first pinch roller 41, the strip-shaped copper foil 100 to be processed is gradually guided to bend into an approximate cylindrical shape. The gradually changing width design of the pre-curling groove 211 can guide the strip-shaped copper foil 100 to be processed to curl more naturally and smoothly. Starting from the width of the groove opening 2111 being equal to the width of the strip-shaped copper foil 100 to be processed, it gradually transitions to the width of the groove bottom 2112 being equal to the width of the cylindrical copper foil 100 to be processed, so that the copper foil 100 to be processed is uniformly stressed during the curling process, reducing stress concentration and material damage that may be caused by sudden deformation, and improving the curling quality and structural strength of the copper foil 100 to be processed. The gradually decreasing width of the pre-curling groove 211 can better control the accuracy and shape of curling. Since the copper foil 100 to be processed is gradually constrained and guided during the curling process, it can more accurately reach the required cylindrical size, reducing curling errors and improving the consistency and qualification rate of the product.

[0040] See Figure 5 and Figure 6 , the curling component 2 further includes a circularizing die 22. A plurality of cylindrical circularizing channels 221 are provided through the circularizing die 22. One end of the circularizing channel 221 is connected to the pre-curling roller 21, and the other end is connected to the cutting component 3. The copper foil 100 to be processed that has passed through the pre-curling groove 211 can pass through the circularizing channel 221. The circularizing channel 221 provides a space for further precise shaping of the copper foil 100 to be processed that has been preliminarily curled through the pre-curling groove 211. The copper foil 100 to be processed passes through the circularizing channel 221. Through the extrusion and constraint of the inner wall of the circularizing channel 221 on the copper foil 100 to be processed, it can ensure that its curling shape is more regular and round, meeting higher accuracy and consistency requirements. Moreover, the circularizing channel 221 plays a good role in constraining and guiding the copper foil 100 to be processed, avoiding irregular deformation or springback phenomena of the copper foil 100 to be processed during the curling process, and ensuring the accuracy of the size and shape of the copper foil 100 to be processed after curling.

[0041] Specifically, the inner diameter of the full - circle channel 221 first gradually decreases and then gradually increases along its own axial direction. The inner diameters at both ends of the full - circle channel 221 are the same and larger than the inner diameter of the middle part. The inner diameter of the middle part of the full - circle channel 221 is equal to the outer diameter of the cylindrical copper foil to be processed 100. Such a design enables the copper foil to be processed 100 to be fully shaped when passing through the middle part, while the larger inner diameters at both ends facilitate the smooth entry and exit of the copper foil to be processed 100, reducing friction and resistance, improving production efficiency, and at the same time reducing damage to the surface of the copper foil to be processed 100.

[0042] After the strip - shaped copper foil to be processed 100 is bent into a cylindrical shape with an opening 101 through the coiling process of the pre - rounding roller 21 and the full - circle die 22, it is necessary to convey the cylindrical copper foil to be processed 100 with the opening 101 to the cutting assembly 3 for cutting.

[0043] See Figure 7 and Figure 8 , the conveying assembly 4 includes a second pinch roller 43. The second pinch roller 43 is arranged between the coiling assembly 2 and the cutting assembly 3. A shaping protrusion 431 is arranged on the outer periphery of the second pinch roller 43 along its own circumferential direction. A plurality of shaping protrusions 431 are arranged at intervals along its own axial direction. The shaping protrusion 431 can be inserted into the opening 101 of the copper foil to be processed 100. The second pinch roller 43 can rotate around its own axis to make the copper foil to be processed 100 move in a straight line. The shaping protrusion 431 can play a role in shaping the opening 101, effectively preventing the coiled copper foil to be processed 100 from deforming or springing back during the conveying process, ensuring the stability of the coiled shape, and thus improving the final quality of the product. The second pinch roller 43 can rotate around its own axis. Through the friction between the shaping protrusion 431 and the copper foil to be processed 100, stable power is provided for the copper foil to be processed 100, enabling the copper foil to be processed 100 to move in a straight line until it is conveyed to the cutting assembly 3.

[0044] The cutting assembly 3 is used to cut the cylindrical copper foil to be processed 100 into multiple segments along its own radial direction. Among them, the cutting assembly 3 selects existing punching equipment, and its working principle and specific structure will not be elaborated here.

[0045] The copper foil cutting and coiling device further includes a collection box. The collection box is communicated with the cutting assembly 3. The copper foil to be processed 100 after being cut by the cutting assembly 3 can fall into the collection box, realizing the automatic collection of the cutting finished products, avoiding the scattering or chaotic placement of the copper foil to be processed 100 after cutting, and ensuring the cleanliness and orderliness of the production site.

[0046] When the copper foil cutting and curling device provided by the embodiment of the present invention is in use, first, the whole piece of copper foil 100 to be processed is wound around the winding roller 51 so that it is wound on the winding roller 51, and the free end of the copper foil 100 to be processed is passed through the feeding slot of the first feeding roller 41 close to the winding roller 51.

[0047] Drive the two rollers of the first feeding roller 41 to rotate relatively. Under the conveyance of the second guiding roller 44 and the first feeding roller 41, part of the copper foil 100 to be processed is conveyed to the laser cutting machine. Under the cutting of the laser cutting machine, the copper foil 100 to be processed is cut from a sheet as a whole into multiple strips.

[0048] After that, the multiple strip-shaped copper foils 100 to be processed are divided into two groups, and the two groups are conveyed along different routes.

[0049] Under the conveyance of the first guiding roller 42 and the first feeding roller 41, the copper foil 100 to be processed is conveyed to the pre-rounding roller 21. The copper foil 100 to be processed passes through the pre-rounding groove 211. The inner wall of the pre-rounding groove 211 squeezes the two sides of the copper foil 100 to be processed. Coupled with the tension provided by the first feeding roller 41, the strip-shaped copper foil 100 to be processed is gradually guided to be bent into an approximate cylindrical shape.

[0050] After that, the copper foil 100 to be processed passing through the pre-rounding groove 211 passes through the full-round channel 221. Through the extrusion and constraint of the inner wall of the full-round channel 221 on the copper foil 100 to be processed, a complete cylindrical copper foil 100 is formed.

[0051] For the copper foil 100 that has completed the curling process, under the rotation of the second feeding roller 43, the shaping protrusion 431 of the second feeding roller 43 is inserted into the opening 101 of the copper foil 100 to achieve the shaping effect on the opening 101. At the same time, the copper foil 100 to be processed is conveyed to the punching equipment.

[0052] The copper foil 100 to be processed is cut into multiple segments along its radial direction by the punching equipment and collected in the collection box.

[0053] The above embodiments only illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments.
