Description

Technical Field

[0001] This utility model relates to the technical field of copper foil wrapping for wires, and specifically to a circular copper foil machine. Background Technology

[0002] Copper sheathing is a common process for electrical wires, where copper foil or braided copper mesh is placed over the insulation layer to enhance wire performance. This copper sheath significantly improves the electromagnetic shielding of the conductor, effectively blocking external electromagnetic interference.

[0003] Traditionally, the copper coating of electrical wires is typically done manually using copper foil. This method is not only inefficient but also results in poor consistency, failing to meet the precision and reliability requirements of modern industry. With technological advancements, automated processes are gradually replacing manual operations, necessitating the design of a circular copper foil machine suitable for automated copper foil coating of wires. Utility Model Content

[0004] This invention proposes a circular copper foil machine. A clamping mechanism achieves precise clamping of copper foil and wire. During the closing process, both ends of the copper foil automatically move towards the wire, ensuring the copper foil's wrapping tendency from the initial stage. The secondary clamping function of the pressing mechanism further eliminates gaps between the copper foil and wire, improving their tightness of adhesion. The copper foil conveying mechanism precisely controls the feeding and retraction of the copper foil, ensuring consistent conveying length each time. The cutting mechanism quickly cuts the copper foil. A turntable mechanism drives the clamping mechanism to rotate, simulating the action of winding copper foil, causing the copper foil to be evenly wound onto the wire. This solves the problems of uneven force and inconsistent number of turns during manual winding, significantly improving the roundness and consistency of the wrapping.

[0080] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0081] See Figures 1-10 A circular copper foil machine includes a machine body 1, wherein the machine body 1 is provided with:

[0082] Clamping mechanism 2, which is used to clamp copper foil 3 and wire 4;

[0083] A copper foil conveying mechanism 7 is used to convey copper foil 3 to the clamping mechanism 2;

[0084] A cutting mechanism 8 is located between the clamping mechanism 2 and the copper foil conveying mechanism 7 to cut the copper foil 3 connected between the clamping mechanism 2 and the copper foil conveying mechanism 7.

[0085] The rotating end of the turntable mechanism 9 is fixedly connected to the clamping mechanism 2 and is used to drive the clamping mechanism 2 to rotate and to wind the copper foil 3 onto the wire 4.

[0086] In this technical solution, the clamping mechanism 2 achieves precise clamping of the copper foil 3 and the wire 4. During the closing process, both ends of the copper foil 3 automatically move towards the wire 4, ensuring the copper foil 3's wrapping tendency towards the wire 4 from the initial stage. The secondary clamping function of the pressing mechanism 5 further eliminates the gap between the copper foil 3 and the wire 4, improving their tightness of adhesion. The copper foil conveying mechanism 7 precisely controls the feeding and retraction of the copper foil 3, ensuring consistent conveying length each time. The cutting mechanism 8 quickly cuts the copper foil 3. The turntable mechanism 9 drives the clamping mechanism 2 to rotate, simulating the action of winding the copper foil 3 (winding the copper foil 3 onto the wire 4), ensuring the copper foil 3 is evenly wound onto the wire 4 (the wire 4 is clamped and stationary). This solves the problems of uneven force and inconsistent number of turns during manual winding, significantly improving the roundness and consistency of the wrapping. The overall structure realizes a fully automated process from copper foil conveying, clamping, pressing, resetting and retraction (material return), cutting and winding, effectively replacing traditional manual operation, greatly improving production efficiency, while ensuring the stability of product quality and meeting the requirements of modern industry for precision and reliability.

[0087] The machine body 1 is also provided with a pressing mechanism 5, which is used to apply pressure to the clamping end of the clamping mechanism 2 to achieve secondary pressing of the copper foil 3 and the wire 4.

[0088] The clamping mechanism 2 includes:

[0089] Lower gripper assembly 10, which is fixedly connected to turntable mechanism 9;

[0090] The upper gripper assembly 11 is elastically and movably connected to the turntable mechanism 9, and a tension spring 51 is provided between the upper gripper assembly 11 and the turntable mechanism 9;

[0091] Both the lower gripper assembly 10 and the upper gripper assembly 11 are provided with arc-shaped grooves 12 that are adapted to the outer contour of the wire 4;

[0092] The body 1 is provided with a gripper separation mechanism 13, which is located below the upper gripper assembly 11.

[0093] In the initial state of the clamping mechanism 2, the upper jaw assembly 11 and the lower jaw assembly 10 are arranged facing each other vertically on the turntable mechanism 9, and the jaw separation mechanism 13 acts on the upper jaw assembly 11 to keep the upper jaw assembly 11 and the lower jaw assembly 10 in an open and separated state.

[0094] When the clamping mechanism 2 is in operation, the actuating end of the jaw separation mechanism 13 disengages from the upper jaw assembly 11, causing the upper jaw assembly 11 to close with the lower jaw assembly 10 under the action of the tension spring 51, and together clamp the copper foil 3 and the wire 4.

[0095] The lower gripper assembly 10 is fixedly connected to the turntable mechanism 9, and the upper gripper assembly 11 is elastically connected to the turntable mechanism 9 and cooperates with the tension spring 51, enabling the upper gripper assembly 11 and the lower gripper assembly 10 to achieve a stable closing action. The arc-shaped groove 12 is adapted to the outer contour of the wire 4, ensuring that the copper foil 3 and the wire 4 can fit tightly against the inner wall of the arc-shaped groove 12 during clamping, ensuring the accurate relative position of the two from the clamping stage and preventing the wire 4 from shifting during the clamping process. The gripper separation mechanism 13 keeps the upper gripper assembly 11 and the lower gripper assembly 10 separated in the initial state, providing sufficient space for the insertion of the copper foil 3 and the wire 4, allowing the wire 4 to be manually placed into the arc-shaped groove 12 of the lower gripper assembly 10. When the clamping mechanism 2 enters the working state, the jaw separation mechanism 13 disengages from the upper jaw assembly 11. Under the action of the tension spring 51, the upper jaw assembly 11 closes with the lower jaw assembly 10, allowing the wire 4 to be manually released. The elastic force of the tension spring 51 makes the clamping action gentler, avoiding damage to the copper foil 3 and the wire 4 caused by rigid clamping. At the same time, it ensures that the clamping force is uniform and continuous, preventing the copper foil 3 from shifting during subsequent winding. This structural design not only ensures the convenience of clamping but also improves the accuracy and stability of clamping, laying a good foundation for subsequent pressing, winding and other processes, thereby improving the overall coating quality of the product.

[0096] The gripper separation mechanism 13 includes:

[0097] Separation cylinder 15, the separation cylinder 15 is used to drive the upper gripper assembly 11 to stay away from the lower gripper assembly 10;

[0098] Connecting plate 16, which is fixedly connected to the piston rod of separating cylinder 15;

[0099] Pushing column 17 is fixedly connected to connecting plate 16. Pushing column 17 moves toward or away from upper gripper assembly 11 via piston rod of separation cylinder 15.

[0100] The separating cylinder 15, as a power source, provides a stable and controllable driving force. Through the piston rod, it drives the connecting plate 16 and the push column 17 to move, thus controlling the separation of the upper gripper assembly 11. The arrangement of the push column 17 ensures more even force distribution. The connecting plate 16 has two symmetrically arranged push columns 17, preventing uneven force distribution and tilting of the upper gripper assembly 11 caused by a single pushing point. This ensures that the upper gripper assembly 11 remains parallel to the lower gripper assembly 10 throughout the separation process.

[0101] The pressing mechanism 5 is located above the clamping mechanism 2 and includes:

[0102] A pressure cylinder 18 is located above the upper gripper assembly 11 and is used to apply pressure to the upper gripper assembly 11.

[0103] The pressure block 19 is fixedly connected to the piston rod of the pressing cylinder 18. The pressure block 19 moves towards or away from the upper gripper assembly 11 via the piston rod of the pressing cylinder 18.

[0104] The upper gripper assembly 11 is provided with a compression spring 23 to provide elastic cushioning when the pressing mechanism 5 applies pressure to the upper gripper assembly 11.

[0105] The pressing mechanism 5 is positioned above the clamping mechanism 2. Driven by the pressing cylinder 18, it causes the pressing block 19 to apply pressure to the clamping end of the clamping mechanism 2, achieving secondary clamping of the copper foil 3 and the wire 4. The compression spring 23 on the upper gripper assembly 11 provides elastic cushioning during the pressing process. The compression spring 23 absorbs some of the impact force, preventing damage to the copper foil 3 and wire 4 from rigid pressure, while ensuring continuous and stable pressure on the contact area, further improving the tightness of the fit between the copper foil 3 and the wire 4. This secondary clamping function effectively compensates for any gaps that may exist during the initial clamping of the clamping mechanism 2, allowing the copper foil 3 to be more firmly wrapped around the wire 4, reducing the risk of loosening of the copper foil 3 in subsequent processes, improving the electromagnetic shielding effect of the product, and enhancing the overall structural stability, providing a reliable guarantee for automated mass production.

[0106] The turntable mechanism 9 includes:

[0107] Fixed plate 24, the fixed plate 24 is fixed on the machine body 1;

[0108] A rotating disk 25 is rotatably mounted on a fixed disk 24, with the fixed disk 24 sleeved around the outer periphery of the rotating disk 25. The rotating disk 25 and the fixed disk 24 form a relative rotatable connection. The rotating disk 25 is provided with an opening slot 27. The first ends of the upper gripper assembly 11 and the lower gripper assembly 10 are both located on the rear side of the rotating disk 25, and the second ends of the upper gripper assembly 11 and the lower gripper assembly 10 extend out of the opening slot 27 and extend along the front side of the rotating disk 25.

[0109] Motor 26, which is located in the rear direction of rotating disk 25 and whose drive shaft is fixedly connected to rotating disk 25 to drive rotating disk 25;

[0110] A bracket 52 is provided at the rear of the rotating disk 25, and the first end of the tension spring 51 is connected to the bracket 52.

[0111] The fixed disk 24 is fixed to the machine body 1 by screws, etc., providing a stable support base for the entire turntable mechanism 9, ensuring that there is no shaking during rotation and improving the stability of the mechanism operation. The rotating disk 25 is rotatably mounted on the fixed disk 24. The relative rotational connection formed by the two makes the rotation of the rotating disk 25 smoother, reduces radial runout, ensures the coaxiality of the clamping mechanism 2 during rotation, and thus ensures the roundness of the copper foil 3 wound on the wire 4. The motor 26, as the drive source, can provide continuous and stable power. Its speed can be precisely controlled to keep the rotation speed of the rotating disk 25 uniform, avoiding problems such as uneven coil spacing, wrinkles, or excessive stretching of the copper foil 3 during winding due to speed fluctuations. The slot 27 on the rotating disk 25 allows the second ends of the upper clamping jaw assembly 11 and the lower clamping jaw assembly 10 to extend smoothly and extend along the front side of the rotating disk 25. This ensures that the clamping jaw assembly will not interfere with the fixed disk 24 or other parts of the machine body 1 during rotation and winding, and facilitates the loading of the wire 4 onto the lower clamping jaw assembly 10 from the outside of the machine body 1. The bracket 52 provides a fixing point for the tension spring 51, ensuring a stable and reliable elastic connection between the upper gripper assembly 11 and the rotating disk 25, so that the upper gripper assembly 11 can always maintain a good fit with the lower gripper assembly 10 during rotation. The overall structural design enables the turntable mechanism 9 to accurately drive the clamping mechanism 2 to complete the simulated copper foil winding action, greatly improving the uniformity and consistency of the copper foil winding and meeting the high precision requirements of modern industry.

[0112] The upper gripper assembly 11 includes:

[0113] Movable component 20, which is movably connected to the rotating disk 25;

[0114] Upper gripper 21, which is mounted on the movable part 20;

[0115] Connector 22, which is fixedly connected to the upper jaw 21, and a compression spring 23 is provided between the connector 22 and the movable part 20;

[0116] The movable part 20 is provided with a mounting groove 28, the upper clamp 21 is convex in shape, the upper clamp 21 is inserted into the mounting groove 28, the step of the upper clamp 21 abuts against the bottom of the movable part 20, and the connecting part 22 is fixed on the upper part of the upper clamp 21 to prevent the upper clamp 21 from detaching from the movable part 20.

[0117] The lower gripper assembly 10 includes:

[0118] Lower gripper 29, wherein the lower gripper 29 is initially positioned vertically opposite to the lower gripper 29;

[0119] Both the upper gripper assembly 11 and the lower gripper assembly 10 include:

[0120] The extension arm 30 extends toward the protruding opening slot 27 and along the front side of the rotating disk 25. The extension arm 30 of the upper gripper assembly 11 is fixedly connected to the movable member 20, and the extension arm 30 of the lower gripper assembly 10 is fixedly connected to the lower gripper 29.

[0121] Connecting arm 31, the first end of which is fixedly connected to extension arm 30;

[0122] The rear part of the rotating disk 25 is provided with a first slide rail 33, and the second end of the connecting arm 31 of the upper gripper assembly 11 is provided with a first slider 32. The first slider 32 slides in cooperation with the first slide rail 33 so that the upper gripper assembly 11 is movably connected to the rotating disk 25.

[0123] The second end of the connecting arm 31 of the lower gripper assembly 10 is fixedly connected to the rear of the rotating disk 25.

[0124] The second end of the tension spring 51 is connected to the second end of the connecting arm 31 of the upper gripper assembly 11.

[0125] In the upper gripper assembly 11, the movable part 20 is movably connected to the rotating disk 25. This, combined with the sliding engagement of the first slider 32 and the first slide rail 33, allows the upper gripper assembly 11 to move smoothly up and down under the action of the tension spring 51. This reduces frictional resistance during movement, improves the smoothness and response speed of the action, and ensures more precise closure of the upper gripper 21 and the lower gripper 29. The upper gripper 21 is convex in shape and inserted into the mounting groove 28, fixed by the connector 22. The upper gripper 21 and the connector 22 are fixed together by screws, effectively preventing the upper gripper 21 from disengaging or shifting during clamping and rotation, ensuring the stability and reliability of the structure. The compression spring 23 between the connector 22 and the movable part 20 further buffers pressure when the pressing mechanism 5 applies pressure. The second end of the connecting arm 31 of the lower gripper assembly 10 is fixed to the rear of the rotating disk 25, ensuring the fixed position of the lower gripper 29, which, together with the upper gripper 21, forms a stable clamping structure. The arc groove 12 is adapted to the outer contour of the wire 4, so that the copper foil 3 can better fit the surface of the wire 4 when clamped, improve the initial wrapping fit, lay a good foundation for the subsequent winding process, and improve the overall clamping accuracy, stability and adaptability, ensuring the quality of the copper foil 3 wrapping.

[0126] The lower jaw 29 has a first positioning groove 29.1 on its inner side for positioning the stripped part of the wire 4, and a second positioning groove 29.2 on the outer side of the lower jaw 29 corresponding to the first positioning groove 29.1 for positioning the insulation layer of the wire 4. The copper foil 3 is used to cover the outer side of the insulation layer of the wire 4.

[0127] The position height of the inner bottom wall of the first positioning groove 29.1 is greater than the position height of the inner bottom wall of the second positioning groove 29.2.

[0128] The copper foil conveying mechanism 7 includes:

[0129] Feeding cylinder 35, which is used to drive the copper foil 3 to feed and transport to the clamping mechanism 2 or to retract and reset.

[0130] Material plate 36 is fixedly connected to the piston rod of feeding cylinder 35 to cooperate with the feeding or retraction of copper foil 3 to the clamping mechanism 2.

[0131] The pallet 37 is movably mounted on the machine body 1, and the material plate 36 is movably connected to the pallet 37 to load the copper foil 3 into the clamping groove of the clamping mechanism 2.

[0132] The lifting cylinder 38 has its piston rod fixedly connected to the support plate 37 to drive the support plate 37 to move up and down on the machine body 1.

[0133] Driven by the lifting cylinder 38, the pallet 37 can move up and down, causing the material plate 36 to move up and down synchronously. When copper foil 3 needs to be conveyed, the pallet 37 rises to align the material plate 36 with the clamping groove. Since the clamping groove is concave, when the material plate 36 is lowered, the copper foil 3 can be placed in the concave groove, ensuring that the copper foil 3 can smoothly enter the clamping mechanism 2. After the conveying is completed, the pallet 37 descends to misalign the material plate 36 with the clamping groove, thus returning to its original position. The material plate 36 plays a traction role for the copper foil 3 during the conveying process.

[0134] In this technical solution, the material plate 36 is provided with a second slider 54, and the bottom of the support plate 37 is provided with a second slide rail 55 that slides with the second slider 54, so that the material plate 36 and the support plate 37 are slidably connected.

[0135] In this technical solution, a movable beam 56 is provided on one side of the pallet 37, and a third slider 57 is provided on the movable beam 56. A third slide rail 58 is provided on the inner side of the machine body 1 to slide in cooperation with the third slider 57. The lifting cylinder 38 drives the movable beam 56 to slide on the inner side of the machine body 1, so as to drive the entire copper foil conveying mechanism 7 to move up and down on the machine body 1.

[0136] In this technical solution, a lifting support mechanism 62 is provided below the material plate 36. When the cutting mechanism 8 cuts the copper foil 3, the lifting support mechanism 62 acts on the copper foil 3 at the bottom of the material plate 36 to fix the copper foil 3.

[0137] The lifting support mechanism 62 includes a copper foil pressing cylinder and a pressing head connected to the piston rod of the copper foil pressing cylinder.

[0138] The copper foil conveying mechanism 7 also includes:

[0139] The first chuck 34 is used to mount the copper foil reel and is rotatably connected to the machine body 1.

[0140] The feeding traction wheel 39 is provided with a connecting rod 40. The first end of the connecting rod 40 is fixedly connected to the support plate 37, and the second end of the connecting rod 40 is rotatably connected to the feeding traction wheel 39.

[0141] The body 1 is also equipped with:

[0142] The second chuck 41 is used to recover the protective layer of the copper foil reel and is rotatably connected to the machine body 1;

[0143] The traction wheel assembly 42 is recovered, and the traction wheel assembly 42 is rotatably connected to the machine body 1.

[0144] The tensioning pulley 43 is retracted and is movably mounted on the machine body 1.

[0145] One end of the copper foil reel is installed on the first chuck 34, and the other end of the copper foil reel is pulled to the bottom of the material plate 36 by the feeding traction wheel 39. After the protective layer 53 of the copper foil reel is separated from the copper foil 3, it is pulled to the recycling roller shaft of the second chuck 41 by the recycling traction wheel group 42 and the recycling tension wheel 43.

[0146] The first chuck 34 rotates to pull and convey the copper foil 3 onto the material plate 36, and the second chuck 41 rotates to realize the recovery of the protective layer 53. The feeding traction wheel 39, the recovery tension wheel 43 and the recovery traction wheel group 42 work together to adjust the motion tension between the copper foil 3 and the protective layer 53.

[0147] In this technical solution, a fourth slider is provided on one side of the recovery tension wheel 43, and a fourth slide rail is provided on the machine body 1 to slide in cooperation with the fourth slider. During the up-and-down movement of the copper foil conveying mechanism 7, since the protective layer 53 remains connected to the copper foil 3 on the conveying end of the copper foil conveying mechanism 7, the recovery tension wheel 43 also moves up and down on the machine body 1.

[0148] The cutting mechanism 8 includes:

[0149] The upper cutting blade assembly includes an upper cutting blade cylinder 44 and an upper cutting blade 45 that is throttledly connected to the piston rod of the upper cutting blade cylinder 44;

[0150] The lower cutter assembly includes a lower cutter cylinder 46 and a lower cutter 47 that is throttledly connected to the piston rod of the lower cutter cylinder 46;

[0151] The upper cutter 45 and the lower cutter 47 are offset to the left and right in the projection direction of the front view of the body 1, and the lower cutter 47 is located below the upper cutter 45.

[0152] In this technical solution, one end of the upper cutter 45 and the lower cutter 47 are both fixed on the connecting frame 61. The connecting frame 61 of both the upper cutter 45 and the lower cutter 47 is provided with a fifth slider 60. The machine body 1 is provided with a fifth slide rail that slides with the fifth slider 60 so that the upper cutter 45 and the lower cutter 47 slide back and forth.

[0153] The feeding traction wheel 39 is connected to the pallet 37 via the connecting rod 40. Moving up and down with the pallet 37, it maintains constant contact with the copper foil 3, ensuring stable traction and guiding the copper foil 3 along a preset path to the material plate 36, preventing deviation during transport. The second chuck 41 is used to recover the protective layer 53 of the copper foil reel. Working in conjunction with the recovery traction wheel set 42 and the recovery tension wheel 43, it achieves automatic separation of the protective layer 53 from the copper foil 3 and automatic recovery of the protective layer 53. This eliminates the need for manual peeling, reducing manual operation steps, improving production efficiency, and avoiding environmental pollution and material waste caused by the indiscriminate disposal of the protective layer 53. The recovery tension wheel 43's up-and-down movement automatically adjusts the tension of the protective layer 53, preventing insufficient tension from causing it to loosen and accumulate, or excessive tension from causing it to break. This ensures smooth separation of the protective layer 53 from the copper foil 3 without affecting the normal transport of the copper foil 3. The overall structure realizes fully automated control of the copper foil 3 from feeding and conveying to the recycling of the protective layer 53, ensuring the stability, accuracy and continuity of the copper foil 3 conveying, and further improving the automation level and production efficiency of the equipment.

[0154] The body 1 is also equipped with:

[0155] The wire clamping and positioning mechanism 48 is used to clamp and fix the wire 4 when the wire 4 is loaded into the clamping mechanism 2.

[0156] The wire clamping and positioning mechanism 48 includes a clamping cylinder 49 and two swinging clamping arms 50. The two clamping arms 50 are connected to the piston rod of the clamping cylinder 49 via a connecting rod assembly to drive the two swinging clamping arms 50 to open and close.

[0157] A lifting support mechanism 62 is provided below the copper foil conveying mechanism 7 to clamp the copper foil 3 during the cutting process.

[0158] The upper cutting cylinder 44 and the lower cutting cylinder 46 drive the upper cutting blade 45 and the lower cutting blade 47 to move respectively. The design of the two blades being staggered left and right and distributed up and down creates a shearing force when cutting the copper foil 3, which can cut the copper foil 3 more easily, reduce the pulling of the copper foil 3 during the cutting process, avoid deformation or tearing of the copper foil 3, ensure a flat and smooth cut surface, and improve the cutting quality.

[0159] The wire clamping and positioning mechanism 48 operates when the wire 4 is inserted into the clamping mechanism 2. It drives the two clamping arms 50 to open and close via the clamping cylinder 49, thus clamping and fixing the wire 4. The clamping force provided by the clamping cylinder 49 is stable and controllable, adjustable according to the material and diameter of the wire 4, ensuring a firm clamping of the wire 4 without deformation due to excessive clamping force. The two clamping arms 50 move synchronously via a linkage assembly, ensuring the clamping force on the wire 4 is evenly distributed on both sides, preventing the wire 4 from shifting during clamping, and ensuring that the axis of the wire 4 is aligned with the axis of the clamping groove in the clamping mechanism 2, improving the coaxiality of the wire 4 clamping. For longer or more flexible wires 4, the clamping and positioning function effectively prevents the wire 4 from shaking or sagging during clamping and subsequent wrapping, ensuring that the wire 4 remains in the preset position and that the copper foil 3 is evenly wrapped around the outer periphery of the wire 4, improving the consistency and roundness of the wrapping. The wire clamping and positioning mechanism 48 can be an existing Y-type finger cylinder.

[0160] Specifically:

[0161] The copper foil reel is loaded into the first chuck 34. The feeding cylinder 35 of the copper foil conveying mechanism 7 drives the material plate 36 forward, and the lifting cylinder 38 drives the support plate 37 downward to load the copper foil 3 at the bottom of the material plate 36 into the arc groove 12 of the lower jaw 29. The wire 4 is loaded onto the lower jaw 29 so that the copper foil 3 is located at the bottom of the wire 4. The wire clamping and positioning mechanism 48 clamps the wire 4. The piston rod of the separating cylinder 15 drives the push column 17 away from the upper jaw assembly 11. The upper jaw assembly 11 moves downward under the action of the tension spring 51 to clamp the copper foil together with the lower jaw 29. The copper foil 3 and wire 4 are connected by a pressing mechanism 5. The copper foil 3 covers the outer surface of the wire 4 at both ends. The pressing mechanism 5 presses down to press the copper foil 3 and wire 4 together for a second time. The feeding cylinder 35 drives the material plate 36 to retract and reset. The lifting cylinder 38 drives the support plate 37 to move up and reset. The pressing cylinder of the lifting support mechanism 62 drives the pressing head to move up and press the copper foil 3 at the bottom of the material plate 4. The cutting mechanism 8 cuts the copper foil 3 connected between the clamping mechanism 2 and the copper foil conveying mechanism 7. The motor 26 of the turntable mechanism 9 starts and drives the turntable 25 to rotate, thereby driving the clamping mechanism 2 to rotate and simulate the winding action of the copper foil 3. The second chuck 41 rotates on the machine body 1 through the drive motor to rewind and recover the protective layer 53. At the beginning, the protective layer 53 is manually peeled off from the copper foil 3, and then the protective layer 53 is wound onto the rotating roller of the second chuck 41.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
