Description

Technical Field

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

[0002] Copper foil is a cathodic electrolytic material, a thin, continuous metal foil deposited on the substrate layer of a circuit board, serving as the conductor in the PCB. It easily adheres to insulating layers, receives printed protective layers, and is etched to form circuit patterns. During production, copper foil needs to be cut to different widths using a slitting device according to requirements.

[0003] The prior art, with publication number CN218224187U, discloses a slitting device for easy collection of waste edges, including an operating table and support legs fixedly connected to the four corners of the bottom of the operating table. Two first mounting plates and two second mounting plates are fixedly connected to the top of the operating table. A discharge roller and a feed roller are rotatably connected between the two first mounting plates and the two second mounting plates, respectively. A second drive motor is fixedly connected to the side end of one of the first mounting plates. The second drive motor is connected to the discharge roller through a coupling, which reduces the occurrence of burrs and bending, and further improves the quality of the copper foil raw material after slitting.

[0004] However, the aforementioned existing technology still has certain shortcomings in its use: First, in the existing technology, the slit waste edges are cut by a reciprocating cutting blade and then guided into the waste collection box at the bottom. During the cutting process, the waste edges are continuously fed, which will cause a certain impact on the cutting blade. In addition, the copper foil has a certain thickness, which can easily cause the cutting blade to deviate, resulting in failure to cut or insufficient cutting. Second, the cut waste will accumulate in a certain area of ​​the waste collection box. Without external force, the waste is prone to falling outside the waste collection box, resulting in poor waste collection. Finally, in real life, copper foil needs to be cut into copper foil of different widths according to needs, but the existing technology lacks the function of adjusting the cutting blade spacing. Therefore, the existing technology needs to be further improved. Utility Model Content

[0035] Various non-limiting embodiments of this utility model are described in detail below. Any number of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0036] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0037] Please see Figure 1-13 The present invention will now be described in detail with reference to the accompanying drawings and embodiments: A slitting device for copper foil production includes a support 1, an unwinding assembly 2 on one side of the support 1, a winding assembly 3 on the other side of the support 1, and a slitting assembly 4 above the support 1. The slitting assembly 4 includes an adjustment part 5 that can move vertically, a slitting part 6 that can move stably at any horizontal position on the output end of the adjustment part 5, and an anti-wrinkle part 7. The winding assembly 3 includes a winding part 8 for winding finished copper foil and a processing part 9 symmetrically arranged on both sides of the winding part 8 for collecting edge material. The processing part 9 can automatically reciprocate horizontally winding the waste material using the rotational force of the winding part 8.

[0038] Please see Figure 1-2 A limit block 10 is symmetrically fixed at one end of the support 1 near the unwinding assembly 2. A pressure roller 11 is rotatably arranged between the limit blocks 10. The pressure roller 11 is higher than the support 1. A limit block 22 is symmetrically fixed at one end of the support 1 near the winding assembly 3. A limit roller 13 is rotatably arranged between the limit blocks 22. By setting the pressure roller 11 and the limit roller 13, the unwound copper foil can be guided and stretched in a straight direction. This can not only effectively prevent the copper foil from shaking in the vertical direction, but also initially prevent wrinkles from occurring during the movement of the copper foil. It is also conducive to the movement of the copper foil and prevents damage to the copper foil.

[0039] Limiting block 2 12 contacts the outer side of the copper foil, and limiting block 2 12 is higher than the top surface of the copper foil. The setting of limiting block 2 12 can also limit and guide the copper foil after it is cut on the outside, and prevent the winding deviation from occurring.

[0040] Please see Figure 2 The unwinding assembly 2 includes a symmetrically arranged support 14. A limiting component 15 is provided at the top of the support 14. A copper foil roll 16 is placed inside the limiting component 15 and can rotate. By setting the limiting component 15, the copper foil roll 16 that has not been cut can be stably placed or quickly disassembled and replaced.

[0041] Please see Figure 2-4The limiting component 15 includes a rotating member 17 rotatably mounted on the top of the second bracket 14. The rotation shaft 66 of the rotating member 17 faces the first bracket 1. The top of the first bracket 1 and the bottom surface of the rotating member 17 are respectively provided with a semi-circular groove 18 and a semi-circular groove 19. When the bottom surface of the rotating member 17 contacts the top surface of the second bracket 14, the semi-circular groove 18 and the semi-circular groove 19 overlap to form a complete circular opening 20. The circular opening 20 is adapted to the size of the rotating shaft 52 of the copper foil roll 16, and the rotating shaft 52 of the copper foil roll 16 is rotatably engaged with the circular opening 20. The rotating member 17 and the second bracket 14... On the right side, a first flange 21 and a second flange 22 are fixedly installed. The top surfaces of the first flange 21 and the second flange 22 are respectively provided with a first opening 23 and a second opening 24. A bolt 25 is installed in the first opening 23 and the second opening 24. The bolt 25 is threaded to the second opening 24, and the bolt 25 is plugged into the first opening 23. Through the setting of the rotating part 17, the first flange 21, the second flange 22, the semi-circular groove 18, the semi-circular groove 19 and the bolt 25, the copper foil roll 16 can be easily placed or disassembled, improving the installation and replacement of the copper foil roll 16.

[0042] Please see Figure 5 The adjustment unit 5 includes columns 26 symmetrically arranged on the front and rear sides of the bracket 1. Each column 26 has a rectangular groove 27 on its inner side. A lead screw 28 is rotatably installed in the rectangular groove 27. A motor 29 is fixedly installed on the top surface of the column 26. The output shaft of the motor 29 passes through the top surface of the column 26 and is fixedly connected to the lead screw 28. A connecting plate 30 is slidably installed in the rectangular groove 27 on both sides. Both ends of the connecting plate 30 are threaded to the lead screws 28 on both sides. Through the cooperation of the motor 29, the lead screw 28 and the connecting plate 30, the height of the slitting part 6 and the anti-wrinkle part 7 can be adjusted, and the opening and closing of the slitting can be controlled in sequence.

[0043] Please see Figure 6-7 The slitting section 6 includes several T-shaped parts 31. A groove 32 is provided on the top surface of the connecting plate 30. The vertical section of the T-shaped part 31 slides in the groove 32, and the horizontal section of the T-shaped part 31 slides in contact with the top surface of the connecting plate 30. A second groove 33 is symmetrically provided on both sides of the groove 32. A third opening 34 is provided on both sides of the horizontal section of the T-shaped part 31, corresponding to the position of the second groove 33. A bolt 35 is inserted into the third opening 34. The bolt 35 can stabilize the T-shaped part 31 at any position of the groove 32 of the connecting plate 30 through the threaded engagement of the nut, and can be adjusted at any equidistant distance. A circular blade 36 is rotatably provided at the bottom end of the T-shaped part 31. A motor 37 is fixedly provided on the side of the bottom end of the T-shaped part 31. The output end of the motor 37 passes through the side of the T-shaped part 31 and is fixedly connected to the circular blade 36. The two outer circular blades 36 are used to cut off the defective parts on the side of the copper foil to ensure the quality of the cut copper foil.

[0044] Please see Figure 6 , 8 -9, the anti-wrinkle part 7 includes symmetrically arranged T-shaped parts 2 38. The vertical section of the T-shaped parts 2 38 slides in the slide groove 1 32. The horizontal section of the T-shaped parts 2 38 is symmetrically provided with through openings 4 39 corresponding to the positions of the slide groove 2 33. Bolts 3 40 are inserted into the through openings 4 39. The bolts 3 40 and nuts stabilize the T-shaped parts 2 38 at any position in the slide groove 1 32. The bottom surface of the vertical section of the T-shaped parts 2 38 is provided with a cylindrical groove 41. A T-shaped part 3 42 is provided in the cylindrical groove 41. The vertical section of the T-shaped part 3 42 slides in the cylindrical groove 41. The vertical section of the T-shaped part 3 42 and the top surface of the cylindrical groove 41 are aligned. A spring 43 is fixedly installed between the two parts. A rectangular groove 44 is opened on the bottom surface of the horizontal section of the T-shaped part 38. Several rollers 45 are rotatably installed in the rectangular groove 44. When the spring 43 is at its original length, the horizontal section of the T-shaped part 38 is below the circular blade 36. Through the arrangement of the T-shaped part 38, the T-shaped part 32, and the spring 43, the circular blade 36 contacts the top surface of the copper foil before descending to cut the copper foil, thereby pressing the copper foil without hindering its movement (the rollers 45 will rotate in the direction of the copper foil), ensuring that the copper foil is deviated during cutting and reducing the impact of the deviated movement on the cutting quality.

[0045] To further ensure more stable vertical sliding of the T-shaped part 42, symmetrical sliding grooves 46 are provided on both sides of the cylindrical groove 41, and protrusions 47 that slide within the sliding grooves 46 are provided on both sides of the vertical section of the T-shaped part 42.

[0046] Please see Figure 10 The winding section 8 includes several supports 48 of different heights. The number and position of the supports 48 are adapted to the number of copper foils cut out and the position of the copper foils. The supports 48 of different heights are staggered. A winding roller 49 is detachably and rotatably mounted on the middle of the upper end of the supports 48. A motor 50 is detachably mounted on one side of the supports 48. The output shaft of the motor 50 passes through the side of the support and is fixedly connected to one end of the winding roller 49. The motors 50 of the supports 48 on the front and rear outer sides are located on the inner side.

[0047] When the copper foil is first installed and cut, the front end of the untreated copper foil roll 16 is pulled out, passes under the limiting roller 13 and falls onto the fixed top surface of the bracket 1. Then, the adjusting part 5 is lowered so that the anti-wrinkle part 7 first limits and presses the copper foil. Then, the front end of the copper foil is cut by the rotating circular blade 36. The copper foil is fed by the pull of the operator. When the cutting is long enough, the copper foil cut at the front end is stabilized on the corresponding winding roller 49. Then, the copper foil is automatically fed by the motor 3 50 to realize the automatic overall cutting of the copper foil.

[0048] Please see Figure 10-13The processing unit 9 includes a U-shaped mounting plate 51, which is set on the ground. One side of the U-shaped mounting plate 51 can be detached. A rotating shaft 52 is rotatably mounted on the upper end of the U-shaped mounting plate 51. The inner end of the rotating shaft 52 extends to the outside of the U-shaped mounting plate 51. A spur gear 1 53 is fixedly mounted on the outer rotating shaft 52. A take-up roller 49 on the outer bracket 3 48 extends to the outside, and a spur gear 2 54 is fixedly mounted on the outer take-up roller 49. A belt 55 is toothed between the spur gear 2 54 and the spur gear 1 53. The arrangement of the spur gear 1 53, the spur gear 2 54, and the belt 55 allows the take-up roller 49 to rotate together with the rotating shaft 52 when it rotates. A U-shaped mounting plate 51 is fixedly equipped with... A limiting plate 56 is provided, with a U-shaped groove 57 on the top surface of the limiting plate 56. A U-shaped component 58 is provided above the U-shaped groove 57, and a limiting block 59 is provided on the bottom surface of the U-shaped component 58. The limiting block 59 is inserted into and slides horizontally within the U-shaped groove 57. A winding roller 60 is rotatably provided at the upper end of the U-shaped component 58. The winding roller 60 is sleeved on the rotating shaft 52 and can rotate together with the rotating shaft 52. The winding roller 60 in the processing unit 9, through the arrangement of spur gear 53, spur gear 54, belt 55, and rotating shaft 52, can fully utilize the rotational force of the outer winding roller 49 to wind the cut waste material together, thereby orderly collecting the waste material for subsequent reuse.

[0049] Specifically, the winding roller 60 has a through groove 61 in the middle that is adapted to the diameter of the rotating shaft 52. The rotating shaft 52 has several connecting grooves 62. A connecting strip 63 adapted to the connecting groove 62 is fixedly installed in the through groove 61. The connecting strip 63 can be inserted into the connecting groove 62. The U-shaped part 58 rotates with the rotating shaft 52. Through the cooperation of the connecting groove 62 and the connecting strip 63, the winding roller 60 rotates together with the rotating shaft 52.

[0050] The number of teeth of spur gear 53 is greater than that of spur gear 54, so that the rotation speed of shaft 52 is less than that of winding roller 49, which prevents the winding roller 60 from pulling the waste material and avoids tearing the copper foil, thus avoiding affecting the copper foil cutting quality.

[0051] Please see Figure 10-13 The processing unit 9 also includes an auxiliary component that enables the winding roller 60 to move horizontally back and forth during the winding process. By setting the auxiliary component, the rotational force of the rotating shaft 52 can be used to drive the winding roller 60, which is winding, to move horizontally, so that the waste material can be wound at different positions of the winding roller 60, thereby improving the utilization rate of the winding roller 60.

[0052] Please see Figure 11-13The auxiliary components include a bevel gear 64 fixed to the end of the rotating shaft 52, a limiting plate 65 fixedly installed on the inner side of the U-shaped mounting plate 51, a rotating shaft 66 rotatably installed through the top surface of the limiting plate 65, a bevel gear 67 meshing with the bevel gear 64 fixedly installed at the top of the rotating shaft 66, a slot 68 opened on the inner side of the U-shaped mounting plate 51 located below the limiting plate 65, a disc 69 fixedly installed at the bottom end of the rotating shaft 66, a cylinder 70 eccentrically installed on the bottom surface of the disc 69, a limiting block 59 sliding in the U-shaped groove 57 with a cylinder 71 fixedly installed on the bottom surface, and a connecting rod 72 hinged between the cylinder 70 and the cylinder 71.

[0053] During the rotation of the rotating shaft 52, the rotating shaft 52 drives the first bevel gear 64 to rotate, the first bevel gear 64 drives the second bevel gear 67 to rotate, the second bevel gear 67 drives the disk 69 to rotate through the rotating shaft 66, and the disk 69 drives the U-shaped part 58 and the winding roller 60 to move horizontally and reciprocally through the eccentrically set cylinder 70, connecting rod 72 and cylinder 71.

[0054] When this scheme is running, first open the rotating part 17 on the second bracket 14, then place the rotating shaft 52 of the copper foil roll 16 into the semi-circular groove 18, and then make the rotating part 17 contact the top surface of the second bracket 14 again, so that the semi-circular groove 19 and the semi-circular groove 18 together limit the rotating shaft 52 of the copper foil roll 16 without hindering its rotation. Then, the bolt 25 passes through the through-hole 23 and is threadedly connected to the through-hole 24. Then, the operator feeds the front end of the copper foil roll 16 through the bottom surface of the pressure roller 11 along the top surface of the first bracket 1.

[0055] When the device moves to directly below the circular blade 36, the start motor 29 drives the lead screw 28 to rotate. The rotation of the lead screw 28 causes the connecting plate 30 to gradually descend. The roller 45 on the bottom surface of the T-shaped part 42 contacts the copper foil and presses it to prevent wrinkles during cutting, thus improving the cutting quality. As the connecting plate 30 continues to move downward, the T-shaped part 42 compresses the spring 43. At the same time, the high-speed rotating circular blade 36 gradually contacts the copper foil and cuts it. The copper foil is fed by the operator pulling it.

[0056] Once the copper foil has been cut to a certain length, the copper foil cut by the workers is stabilized on the winding roller 49 at the corresponding position, and then their respective motors 50 are started at the same time, thereby realizing the automatic cutting of the copper foil roll 16.

[0057] During the slitting process, the two outer circular blades 36 cut off the waste edges of the copper foil. Then, while stabilizing the slitting copper foil onto the take-up roller 49, the operator also stabilizes the front end of the waste edge onto the winding roller 60. As the motor 3 50 drives the take-up roller 49 to rotate, the take-up roller 49 drives the spur gear 2 54 to rotate. The spur gear 2 54 drives the spur gear 1 53 to rotate via the belt 55. The spur gear 1 53 drives the rotating shaft 52 to rotate, and the rotating shaft 52 drives the winding roller 60 to rotate. This gradually winds and collects the waste edge. Since the number of teeth of the spur gear 1 53 is greater than the number of teeth of the spur gear 2 54, the rotation speed of the winding roller 60 is slower than that of the take-up roller 49. This prevents the winding roller 60 from tearing the copper foil when winding the waste edge, ensuring the quality of copper foil slitting.

[0058] As the rotating shaft 52 rotates, it also drives the first bevel gear 64 to rotate. The first bevel gear 64 drives the second bevel gear 67 to rotate. The second bevel gear 67 drives the disc 69 to rotate through the rotating shaft 66. The rotation of the disc 69 drives the first cylinder 70 to revolve with the disc 69. The first cylinder 70 drives the third limiting block 59 to move horizontally back and forth along the U-shaped groove 57 through the connecting rod 72. This causes the winding roller 60 to move horizontally back and forth while winding, so that the waste material is spirally wound up, preventing concentrated winding and improving space utilization.

[0059] When the spacing of the circular blade 36 needs to be adjusted, first loosen the bolt 2 35, then move the T-shaped part 31 along the slide groove 32. When it is moved to the desired position, tighten the bolt 2 35 again.
