Description

Technical Field

[0001] This utility model relates to the field of copper foil tape production technology, and in particular to a winding device for copper foil tape production. Background Technology

[0002] Copper foil tape is a functional tape made by coating a copper foil substrate with a specific adhesive. It combines the properties of metallic copper with the easy-to-apply and easy-to-process attributes of tape. As a key functional material in the fields of electronics and new energy, the quality of the winding process in the production of copper foil tape directly determines the product performance and its compatibility with subsequent processing.

[0003] Traditional copper foil tapes, when wound, are prone to lateral deviation due to their thin and soft substrate. This is easily caused by factors such as tension fluctuations, equipment vibration, or wear of the guide structure during production. As a result, the edges of the wound tape may appear as flared, stepped, or wrinkled shapes. Edge wear can lead to copper foil shedding, resulting in decreased conductivity. Long-term deviation can also cause uneven roll diameter, leading to uncontrolled tension during subsequent slitting and a risk of tape breakage. Therefore, these methods have certain limitations.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example

[0021] Please see Figures 1-5 This utility model provides a technical solution:

[0022] A winding device for producing copper foil tape includes a base 1, a winding mechanism 2 on the top of the base 1, a limit mechanism 3 mounted on the winding mechanism 2, an mounting plate 8 fixedly mounted on the back of the top of the base 1, a top plate 4 fixedly mounted on the top of the front of the mounting plate 8, and grooves 5 symmetrically formed on both sides of the top front of the top of the top plate 4. An adjustment mechanism 6 is installed in each of the two grooves 5. The adjustment mechanism 6 includes two lead screws 601, two adjusting sleeves 602, two position sensors 603, a controller 604, and a handwheel 605. Both lead screws 601 are rotatably mounted on the inner wall of the grooves 5. Both adjusting sleeves 602 are threadedly connected to the outer wall of the adjacent lead screw 601. Both position sensors 603 are fixedly mounted on the bottom end of the corresponding adjusting sleeve 602. The controller 604 is fixedly mounted on one of the adjusting sleeves 602. At the top of 2, two handwheels 605 pass through the groove 5 and are fixedly connected to one end of the adjacent lead screw 601. A buzzer 7 is fixedly installed in the middle of the top of the top plate 4. The winding mechanism 2 and the limiting mechanism 3 at the top of the base 1 form a basic support. Together with the adjustment mechanism 6 on the back mounting plate 8, the edge offset can be monitored in real time during winding. Two position sensors 603 and motor 206 are electrically connected to controller 604. The buzzer 7 is electrically connected to an external power supply through the controller 604. The position sensor 603 transmits the tape edge position data to the controller 604 in real time, forming a dynamic feedback loop. When the offset exceeds the safety threshold, the controller 604 immediately triggers the buzzer 7 to sound and light alarm, and at the same time cuts off the power to motor 206, so that the operator can quickly intervene.

[0023] In this embodiment, the winding mechanism 2 includes two support frames 201, two retaining rings 202, two retaining slots 203, a take-up shaft 204, two retaining blocks 205, and a motor 206. The two retaining rings 202 are rotatably mounted on the top of the inner wall of the corresponding support frame 201. The two retaining slots 203 are opened on the adjacent side of the two retaining rings 202. The two retaining blocks 205 are fixedly mounted on both ends of the take-up shaft 204. The two retaining blocks 205 are engaged with the inner wall of the adjacent retaining slot 203. The motor 206 is fixedly mounted on the top of the outer wall of one of the support frames 201. The output end of the motor 206 passes through one of the support frames 201 and is fixedly connected to the end of the adjacent retaining ring 202. The retaining blocks 205 at both ends of the take-up shaft 204 engage with the retaining slots 203 of the retaining rings 202, which allows for quick disassembly and installation of the take-up shaft 204, facilitating the rapid unloading of the copper foil tape.

[0024] In this embodiment, a sliding groove is provided on one side of the top of the base 1. The bottom end of one support frame 201 is slidably connected to the inner wall of the sliding groove, and the other support frame 201 is fixedly installed on the other side of the top of the base 1. The limiting mechanism 3 includes two threaded sleeves 301, two screws 302, and two compression pads 303. The two threaded sleeves 301 are fixedly installed at the bottom of one of the support frames 201. The screws 302 are threadedly connected to the inner wall of the adjacent threaded sleeves 301. The top ends of the two compression pads 303 are fixedly connected to the middle of the bottom end of the adjacent screws 302 through a set rotating shaft. The bottom ends of the two compression pads 303 are pressed against the top of the base 1. The cooperation between the sliding support frame 201 and the sliding groove of the base 1 realizes the function of adjusting the distance between the two support frames 201. The setting of the limiting mechanism 3 plays the role of limiting one of the support frames 201.

[0025] In this embodiment, a pressing mechanism 9 is installed on the mounting plate 8. The pressing mechanism 9 includes two connecting shafts 901, two extension rods 902, a pressure roller 903, a connecting plate 904, and multiple tension springs 905. The two connecting shafts 901 are fixedly installed on both sides of the top of the inner wall of the mounting plate 8. The two extension rods 902 are rotatably installed on the inner wall of the corresponding connecting shafts 901. The two ends of the pressure roller 903 are rotatably connected to the other end of the corresponding extension rod 902. The connecting plate 904 is fixedly installed at the bottom end of the two extension rods 902. One end of each of the multiple tension springs 905 is fixedly installed at the bottom end of the connecting plate 904, and the other end is fixedly connected to the inner wall of the mounting plate 8. The tension springs 905 adopt a variable stiffness design, so that the contact pressure of the pressure roller 903 on the copper foil tape is automatically adjusted as the roll diameter increases, ensuring that the compaction effect is consistent at different roll diameter stages and avoiding defects such as outer ring loosening or inner ring indentation caused by traditional fixed pressure rollers 903.

[0026] Working principle: When the copper foil tape is drawn out from the unwinding end and passes through the take-up shaft 204 of the winding mechanism 2, the handwheel 605 is manually turned according to the width of the copper foil tape. This drives the corresponding lead screw 601 to rotate, converting the rotary motion into linear motion. This, in turn, drives the adjusting sleeve 602 to move horizontally, adjusting the position sensor 603 to the position of the corresponding edge of the copper foil tape. The position sensor 603 collects the tape edge position data in real time and transmits it to the controller 604 for comparison with preset parameters. When the detected offset exceeds the threshold, the controller 604 immediately activates the buzzer. 7. An alarm is issued, and the motor 206 is simultaneously decelerated or stopped to remind the operator to intervene in time. At the same time, the pressure roller 903 of the pressing mechanism 9 presses the wound copper foil tape through the tension spring 905. When unloading, the screw 302 of the limiting mechanism 3 is rotated to make the pressing pad 303 disengage from the base 1, release the lock on the sliding support frame 201, and push the support frame to move outward along the slide groove to increase the distance between the two support frames. This allows the locking block 205 to disengage from the locking groove 203, so that the winding shaft 204 can be disassembled separately, making it easy to quickly remove the copper foil tape from the winding shaft 204.
