[0036] As mentioned in the background technology, foil production technology is an indispensable part of modern industry, especially in the fields of electronics, automobiles, aerospace, etc. For example, copper foil, as one of the important metal foils, is mainly used to make conductive materials for printed circuit boards (PCBs) and electrode materials for lithium batteries. The production of traditional copper foil mainly adopts electrolysis or rolling method, among which electrolysis has become the mainstream in the current industry due to its low equipment investment and low production cost. The core processes include copper dissolution, raw foil, post-processing and slitting.

[0037] In the production process of foil, winding and joining are key steps, which directly affect the quality and production efficiency of the product. At present, winding and joining mainly rely on automation equipment, such as automatic roll changing and winding devices, which can realize the fully automatic roll changing and winding process, saving labor and time costs.

[0038] However, the current automatic roll changing and rewinding devices still require manual cutting and laminating of the tape, which not only increases labor costs, but may also lead to problems such as material waste and bottom wrinkles, affecting product quality and work efficiency.

[0039] In view of this, an embodiment of the present application provides a foil winding and joining device, including a base, a lifting mechanism and a foil sticking shaft lifting unit. The lifting mechanism is movably mounted on the base and can move in the horizontal direction. The foil sticking shaft lifting unit includes a lifting assembly and at least one foil sticking shaft, the lifting assembly can be movably connected to the lifting mechanism, and the foil sticking shaft is connected to the lifting assembly. Thus, the lifting mechanism can drive the foil sticking shaft lifting unit to rise and fall or move in the horizontal direction. Among them, the foil sticking shaft includes a first foil sticking shaft, the first foil sticking shaft is rotatably connected to the lifting assembly, and the lifting assembly can drive the first foil sticking shaft to rise and fall. In this way, the lifting mechanism drives the foil sticking shaft lifting unit to move and rise in the horizontal direction, and the lifting assembly drives the first foil sticking shaft to rise and fall, so that the horizontal movement and lifting of the first foil sticking shaft can be realized, so that the first foil sticking shaft is tightly attached to the outer peripheral surface of the winding roller. Furthermore, by rotating the first foil sticking shaft and connecting it to the lifting assembly, after the first foil sticking shaft is attached to the outer circumference of the winding roller, as the lifting assembly drives the first foil sticking shaft to rise, the first foil sticking shaft can move along the outer circumference of the winding roller, thereby pressing the foil material onto the tape of the winding roller. This replaces the process of manual tape sticking, effectively solving the problem of waste of the bottom roll core of the foil material and wrinkles on the bottom layer. In addition, the operation process of foil winding is simplified, and the production efficiency and production quality of the foil material are improved.

[0040] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0041] Figure 1 A schematic diagram of the three-dimensional structure of the foil winding and joining device provided in an embodiment of the present application. Figure 2 This is a schematic front view of the structure of the foil winding and joining device provided in an embodiment of the present application.

[0042] Reference Figure 1 and Figure 2 As shown, the embodiment of the present application provides a foil winding and joining device 10 (hereinafter referred to as the winding and joining device), which can be widely used in the processing of foil 20, and efficiently realizes the winding and joining process of foil 20 through automated operation, thereby replacing the traditional manual tape application process. The operation error caused by human factors is reduced, and the problem of wrinkles and waste in the core of the foil 20 is solved through precise mechanical control, which can significantly improve production efficiency and production quality.

[0043] Combination Figure 1 and Figure 2As shown, the winding and joining device 10 includes a base 100, a lifting mechanism 200, and a foil sticking shaft lifting unit 300. The lifting mechanism 200 can be movably mounted on the base 100, and the lifting mechanism 200 can move in the horizontal direction. The foil sticking shaft lifting unit 300 can be movably connected to the lifting mechanism 200, and the lifting mechanism 200 can drive the foil sticking shaft lifting unit 300 to rise and fall and move in the horizontal direction.

[0044] Reference Figure 1 As shown, the base 100 is provided with a traction level device 110. Exemplarily, the traction level device 110 can use a cylinder as a core component, and its structure includes a cylinder body 111 and a piston 112, and the piston 112 is driven by compressed air to perform traction movement. The cylinder can also be connected to a solenoid valve (not shown in the figure), which can accurately control the air intake and exhaust process of the cylinder, thereby realizing the control of the movement direction of the piston 112. When compressed air enters the cylinder, the piston 112 is thrust and starts to move, and the solenoid valve controls the rise or fall of the piston 112 by adjusting the direction of the air flow, which can realize the stable and reliable movement function of the traction level device 110.

[0045] Of course, the design of the traction horizontal device 110 is not limited to the cylinder structure, and can be a variety of structural forms. Exemplarily, the traction horizontal device 110 can be set as a hydraulic cylinder structure, and the piston 112 is driven by the pressure of the hydraulic oil to achieve a smooth traction movement. Alternatively, the traction horizontal device 110 can also be a linear module structure, and a high-precision traction movement can be achieved through a motor drive and a precision guide rail system. As long as the horizontal movement of the traction horizontal device 110 can be achieved, this embodiment does not impose specific restrictions on this.

[0046] Continue to refer to Figure 1 As shown, the lifting mechanism 200 connected to the base 100 includes a frame 210, and the frame 210 can be movably connected to the base 100. In addition, the frame 210 is connected to the traction horizontal device 110, and can move in the horizontal direction driven by the traction horizontal device 110. Taking the traction horizontal device 110 as a cylinder as an example, the frame 210 can be connected to the piston 112, for example, the frame 210 is connected to the end of the piston 112 away from the cylinder body 111.

[0047] In a possible embodiment, the base 100 may be provided with a guide rail 120, and the extension direction of the guide rail 120 may be consistent with the extension direction of the traction horizontal device 110. A guide groove 220 may be provided at the corresponding position of the frame 210 and the guide rail 120. The guide rail 120 may extend into the guide groove 220 and may slide along the guide rail 120. In this way, by setting the guide rail 120 and the guide groove 220, it can be ensured that the frame 210 will not deflect during the movement, and can maintain linear motion, thereby improving the accuracy and reliability of the movement. In addition, the guide rail 120 and the guide groove 220 can be set as a surface with a low friction coefficient to reduce the friction between the two, thereby reducing the wear and energy loss of the guide rail 120 and the guide groove 220.

[0048] For example, two guide rails 120 may be provided, and the two guide rails 120 are respectively located on both sides of the base 100, and the traction level device 110 is located between the two guide rails 120. At the same time, two guide grooves 220 are also provided at corresponding positions of the frame 210. In this way, the two guide rails 120 can be respectively extended into the guide grooves 220 on both sides of the frame 210, so that the overall force of the frame 210 is more balanced, the moving trajectory is more accurate, and the movement is more stable during the movement process.

[0049] Of course, the frame 210 may be provided with a guide rail 120 and the base 100 may be provided with a guide groove 220, as long as the frame 210 can be moved horizontally relative to the base 100, and this embodiment does not impose any specific restrictions on this.

[0050] Combination Figure 1 and Figure 2 The lifting mechanism 200 further includes a traction lifting device 230, which is connected between the frame 210 and the foil sticking shaft lifting unit 300. It is understandable that the traction lifting device 230 can also be a variety of structural forms such as a cylinder, a hydraulic cylinder or a linear module, as long as the lifting of the traction lifting device 230 can be achieved, and this embodiment does not impose any specific restrictions on this.

[0051] The foil-laminating shaft lifting unit 300 is connected to the traction lifting device 230 , and the foil-laminating shaft lifting unit 300 can be raised or lowered under the driving of the traction lifting device 230 .

[0052] In a possible implementation, a guide assembly 240 may be further provided between the lifting mechanism 200 and the foil sticking shaft lifting unit 300. The guide assembly 240 may more stably connect the lifting mechanism 200 and the foil sticking shaft lifting unit 300, thereby increasing the stability and reliability of the winding and joining device 10. Furthermore, the guide assembly 240 may also guide the lifting and lowering of the foil sticking shaft lifting unit 300 under the drive of the traction lifting device 230.

[0053] For example, two sets of guide assemblies 240 may be respectively provided at both ends of the frame 210, and the two sets of guide assemblies 240 may be symmetrically distributed relative to the traction lifting device 230. Such a configuration can effectively improve the balance of the structure and reduce the deviation and shaking that may be caused during the lifting process.

[0054] The guide assembly 240 should have high strength and wear resistance to ensure its reliability and durability in long-term use. In addition, the surface of the guide assembly 240 can be precisely processed and coated with a material with a low friction coefficient to reduce friction resistance and wear. Its design can take many forms, such as a combination of a guide rod and a sliding sleeve, or a combination of a linear guide rail and a slider.

[0055] Exemplarily, the guide assembly 240 may include a guide shaft 241 and a guide ring 242, wherein the guide shaft 241 is inserted into the guide ring 242. Furthermore, the two ends of the guide shaft 241 extend out of the guide ring 242 to provide necessary moving space. In addition, the two ends of the guide shaft 241 may also be provided with a fixing ring 243, which may play a role in limiting the moving range of the guide shaft 241, and the guide shaft 241 may move up and down relative to the guide ring 242 within the distance range between the fixing rings 243 at both ends. Among them, the guide ring 242 is fixedly connected to the frame 210, and the upper end of the guide shaft 241 is fixedly connected to the foil sticking shaft lifting unit 300 through the fixing ring 243 and the connecting plate. In this way, when the traction lifting device 230 is started, the guide shaft 241 may also move up and down accordingly.

[0056] Continue to refer to Figure 1 and Figure 2 As shown, the foil sticking shaft lifting unit 300 includes a lifting assembly 310 and at least one foil sticking shaft 320 , and the foil sticking shaft 320 is connected to the lifting assembly 310 .

[0057] The lifting assembly 310 includes a support frame 311 and a foil sticking shaft lifting device 312. The support frame 311 can be used to fix the foil sticking shaft lifting device 312 to ensure the stability of the lifting assembly 310. Exemplarily, the support frame 311 can include a fixed frame 3111 and a movable member 3112. The fixed frame 3111 is connected to the lifting mechanism 200 and can follow the lifting mechanism 200 to drive the foil sticking shaft lifting unit 300 to rise and fall as a whole.

[0058] One end of the foil sticking shaft lifting device 312 is fixedly connected to the fixed frame 3111, and the other end is connected to the movable part 3112, and the foil sticking shaft lifting device 312 can drive the movable part 3112 to move up and down. In order to stably support the lifting and lowering of the foil sticking shaft 320, at least two foil sticking shaft lifting devices 312 can be provided. Exemplarily, two foil sticking shaft lifting devices 312 can be provided, and the two foil sticking shaft lifting devices 312 are both fixed on the fixed frame 3111, and the two foil sticking shaft lifting devices 312 can be symmetrically distributed relative to the axial center line of the fixed frame 3111. Similarly, the foil sticking shaft lifting device 312 can also be a variety of structural forms such as a cylinder, a hydraulic cylinder or a linear module, as long as the lifting and lowering of the foil sticking shaft lifting device 312 can be achieved, and this embodiment does not impose specific restrictions on this.

[0059] The foil sticking shaft 320 includes a first foil sticking shaft 321. The first foil sticking shaft 321 can be connected to the movable member 3112, and the foil sticking shaft lifting device 312 can drive the first foil sticking shaft 321 to rise or fall through the movable member 3112.

[0060] It should be noted that the first foil sticking shaft 321 is rotatably connected to the movable member 3112. Figure 1 As shown, the foil sticking shaft lifting unit 300 may also be provided with a swinging member 330 , one end of which may be fixedly connected to the first foil sticking shaft 321 , and the other end of which is connected to the movable member 3112 and may swing relative to the circumferential direction of the movable member 3112 .

[0061] Continue to refer to Figure 1 As shown, the foil sticking shaft lifting unit 300 may further include an elastic member 340, and the two ends of the elastic member 340 are respectively connected to the movable member 3112 and the swing member 330. When the first foil sticking shaft 321 rises to contact the outer surface of the winding roller, the elastic member 340 can be stretched, so that the first foil sticking shaft 321 can move along the outer circumference of the winding roller as the spring is stretched, thereby pressing the foil material 20 against the tape of the winding roller.

[0062] Figure 3 This is a schematic diagram of the structure of the foil sticking shaft in the foil winding and joining device provided in the embodiment of the present application. Figure 3 As shown, the material of the foil sticking shaft 320 needs to have good lubricity, flexibility, wear resistance and other characteristics. For example, the material of the foil sticking shaft 320 can be lubricating resin. In this way, when the foil sticking shaft 320 abuts against the outer peripheral surface of the winding roller, the lubricating resin can provide good self-lubrication and wear resistance, and can also effectively disperse the pressure to prevent scratches or indentations on the foil. At the same time, the lubricating resin has antistatic and chemical stability, ensuring the integrity and quality of the foil during processing and handling.

[0063] In addition, when the first foil sticking shaft 321 is in an upright state and the first foil sticking shaft 321 is in close contact with the winding roller (see Figure 8 As shown), the first foil axis 321 deviates from the winding roller (see Figure 4 The height center line of the first winding roller 30 or the second winding roller 40 is located on one side of the height center line of the winding roller. In this way, when the lifting assembly 310 continues to drive the first foil sticking shaft 321 to rise, the first foil sticking shaft 321 can move along the outer circumference of the winding roller.

[0064] The foil sticking shaft may further include a second foil sticking shaft 322, which may be fixedly connected to the fixing frame 3111. In addition, the second foil sticking shaft 322 avoids the movable part 3112, that is, the second foil sticking shaft 322 will not move up and down as the foil sticking shaft lifting device 312 is lifted or lowered.

[0065] Reference Figure 1 and Figure 2 As shown, the second foil sticking shaft 322 can be directly fixedly connected to the fixing frame 3111, or the support frame 311 can also be provided with a support shaft 3113, and the second foil sticking shaft 322 is fixedly connected to the fixing frame 3111 through the support shaft 3113. Specifically, the movable member 3112 can be provided with a through hole for the support shaft 3113 to pass through, one end of the support shaft 3113 can pass through the through hole and be fixedly connected to the second foil sticking shaft 322, and the other end of the support shaft 3113 is fixedly connected to the fixing frame 3111.

[0066] In this way, when the foil sticking shaft lifting device 312 is started, the foil sticking shaft lifting device 312 can drive the first foil sticking shaft 321 to rise or fall through the movable part 3112, while the second foil sticking shaft 322 will avoid the movable part 3112 and will not rise or fall with the foil sticking shaft lifting device 312. Through this separate motion mechanism, the winding and joining device 10 can achieve more efficient function distribution, reduce energy consumption and mechanical wear caused by unnecessary motion, thereby improving work efficiency and extending the service life of the winding and joining device 10.

[0067] In addition, the support shaft 3113 can also provide necessary mechanical support for the support frame 311 by firmly connecting the movable part 3112 with the fixed frame 3111, which can effectively disperse and support various loads generated by the frame 311 during operation, reduce structural deformation caused by movement or external force, and significantly enhance the stability and reliability of the support frame 311.

[0068] Exemplarily, the second foil shaft 322 and the first foil shaft 321 can be symmetrically arranged and respectively located on both sides of the height center line of the winding roller. That is to say, before the first foil shaft 321 rises, the tops of the first foil shaft 321 and the second foil shaft 322 can be flush, and the distances between the first foil shaft 321 and the second foil shaft 322 and the height center line of the winding roller are consistent. In this way, the forces exerted on the winding roller by the first foil shaft 321 and the second foil shaft 322 can be more balanced, thereby better supporting the winding roller. At the same time, such an arrangement can make the distance between the second foil shaft 322 and the first foil shaft 321 larger. When the first foil shaft 321 rises to abut against the outer peripheral surface of the winding roller, the larger distance can reserve more swing space for the first foil shaft 321.

[0069] Reference Figure 2 As shown, the lifting assembly 310 also includes a cutter assembly 313, which is movably connected to the support frame 311 and can move along the axial direction of the foil sticking shaft 320. The cutter assembly 313 can be connected to the fixed frame 3111. Under the driving action of the lifting mechanism, the cutter assembly can be raised and lowered synchronously with the fixed frame. Alternatively, the cutter assembly 313 can also be connected to the movable member 3112. In this way, on the basis of the lifting mechanism driving the cutter assembly to rise and fall, the movable member 3112 can drive the cutter assembly 313 to further rise or fall.

[0070] The cutter assembly 313 can be used to cut the foil material 20 after the winding roller is wound. Exemplarily, the cutter assembly 313 can be set as a pneumatic cutter structure. Specifically, the cutter assembly 313 may include a blade, a blade mold frame, a rodless cylinder, a piston and a slider (not shown in the figure). When the cutter assembly 313 is started, the rodless cylinder is started, and the compressed air pushes the internal piston to move the slider along the axial direction of the cylinder. The blade mold frame is connected to the slider, driving the blade to slide along the axial direction of the foil sticking shaft, thereby achieving cutting of the foil material 20. The design of the rodless cylinder can reduce the occupied space of the equipment and provide a fast and stable cutting action.

[0071] The specific working process of the winding and joining device 10 is shown in Figures 4 to 10 shown.

[0072] Figure 4 This is a schematic diagram of the first winding roller winding state provided in an embodiment of the present application. Figure 5 This is a schematic diagram of the state of applying tape on the second winding roller in an embodiment of the present application. Figure 6 This is a schematic diagram of the roll changing state of an embodiment of the present application.

[0073] Reference Figure 4 As shown in FIG. 1 , during the winding process of the first winding roller 30 , the winding joint device 10 remains in an inactive state. Figure 5 and Figure 6As shown, after the first winding roller 30 is wound up, the isolation films on both sides of the double-sided tape 70 are torn off, and one side of the double-sided tape 70 is attached to the second winding roller 40, and the second winding roller 40 is placed on the production line of the foil 20. Afterwards, the positions of the first winding roller 30 and the second winding roller 40 are interchanged by turning over the main shaft 50.

[0074] Among them, two guide rollers 60 can be arranged on both sides of the main shaft 50. The two guide rollers 60 are symmetrically distributed relative to the main shaft and extend along the axial direction of the main shaft 50. The guide rollers 60 can provide a tension to the foil so that the foil is in a taut state during the roll changing process to prevent wrinkles, thereby ensuring the flatness and quality of the foil 20.

Fig. 9 A schematic diagram of the state of a lifting unit in a foil winding and joining device provided in an embodiment of the present application when it is started.

[0076] Reference Figure 7 As shown, after the positions of the first winding roller 30 and the second winding roller 40 are interchanged, the traction horizontal device 110 is started, and the driving base 100 drives the lifting mechanism 200 and the foil sticking shaft lifting unit 300 to move leftward in the horizontal direction until the first foil sticking shaft 321 and the second foil sticking shaft 322 are symmetrically distributed on both sides of the height center line of the first winding roller 30.

[0077] Reference Figure 8 As shown, the traction lifting device is started, and the driving frame drives the foil sticking shaft lifting unit to rise until the first foil sticking shaft 321 and the second foil sticking shaft 322 abut against the outer peripheral surface of the first winding roller 30. After that, the cutter assembly 313 is started, the rodless cylinder is started, and the compressed air pushes the internal piston 112 to move the slider along the axial direction of the cylinder. The blade mold frame is connected to the slider, driving the blade to slide along the axial direction of the foil sticking shaft, thereby realizing the cutting of the foil material 20.

[0078] Reference Fig. 9 As shown, after the foil material 20 is cut from the first winding roller 30, the foil sticking shaft lifting unit 300 is started. The foil sticking shaft drives the connecting member to rise, and the elastic member 340 is stretched, driving the swing member 330 to swing along the circumference of the connecting member, so that the first foil sticking shaft 321 moves along the outer circumference of the second winding roller 40. In this way, the foil material 20 is pressed against the double-sided tape 70 of the second winding roller 40, and the foil splicing process is completed.

[0079] Fig.10 The path of the foil after the foil is successfully connected is provided in the embodiment of the present application. Fig.10 As shown, after the foil material 20 is pressed against the second winding roller 40, the foil sticking shaft lifting device 312 is started to drive the first foil sticking shaft 321 to be flush with the top of the second foil sticking shaft 322. Then, the traction lifting device 230 is started to drive the frame 210 to drive the foil sticking shaft lifting unit 300 to descend. The traction leveling device 110 is started to drive the base 100 to drive the lifting mechanism 200 and the foil sticking shaft lifting unit 300 to move rightward in the horizontal direction, so that the winding joint device 10 returns to the initial state.
