Description

Technical Field

[0001] The invention relates to the technical field of copper foil production, in particular to a copper foil winding device. Background Art

[0002] Copper foil is a cathodic electrolytic material, a thin, continuous metal foil precipitated on the substrate layer of the circuit board, which serves as the conductor of the PCB. It is easy to adhere to the insulating layer, accept the printed protective layer, and form a circuit pattern after corrosion. Copper foil has low surface oxygen characteristics and can be attached to various substrates, such as metals, insulating materials, etc., and has a wide temperature range of use. It is mainly used for electromagnetic shielding and antistatic. The conductive copper foil is placed on the substrate surface and combined with the metal substrate. It has excellent conductivity and provides electromagnetic shielding effect. It can be divided into: self-adhesive copper foil, double-conductor copper foil, single-conductor copper foil, etc. Electronic grade copper foil (purity above 99.7%, thickness 5um-105um) is one of the basic materials of the electronics industry.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-9 , the present invention provides a technical solution:

[0034] Embodiment 1: A copper foil winding device: comprising a winding bin 1, a conveying platform 2, a guide platform 3 and a pressing bin 4, wherein a winding chamber 1 is provided inside the winding bin 1, the pressing bin 4 is installed at one end inside the winding chamber 11, the guide platform 3 is installed on one side of the guide platform 3, and the conveying platform 2 is arranged on one side of the winding bin 1 close to the guide platform 3;

[0035] A guide frame 21 is installed on one side of the conveying platform 2, and a conveying roller 22 is arranged on the top of the guide frame 21 and the conveying platform 2;

[0036] The winding chamber 11 is provided with a mounting groove 15 near the conveying platform 2, a lower conveying frame 16 is installed in the mounting groove 15 area, a lower fixing plate 161 is installed on the top of the lower conveying frame 16, and lower conveying rollers 162 are installed at both ends of the lower fixing plate 161;

[0037] An upper pressing frame 17 is installed inside the pressing bin 4, an upper pressing plate 171 is installed at the bottom of the upper pressing frame 17, and upper pressing rollers 172 are installed at both ends of the upper pressing plate 171;

[0038] A vertical frame 13 is installed in the winding chamber 11. The vertical frame 13 is symmetrically arranged in two groups. A winding electric roller 14 is installed between the two groups of vertical frames 13.

[0039] A guide roller 31 is provided at the bottom of the guide platform 3;

[0040] A lifting channel 12 is provided on the top of the winding bin 1, and the lifting channel 12 is connected to the winding chamber 11;

[0041] In this embodiment, the copper strip is placed on the top of the conveying roller 22 on the top of the guide frame 21 on one side of the conveyor platform 2. The conveying roller 22 in this area will convey the copper strip, so that one end of the steel strip is conveyed along the guide frame 21 to the conveying roller 22 on the top of the conveyor platform 2. During the movement of the end of the copper strip, when the end of the copper strip moves between the guide platform 3 and the conveyor platform 2, the guide roller 31 at the bottom of the guide platform 3 will press the upper surface of the copper strip, so that when the burr cutting band on the side of the copper strip is cut off, the copper strip as a whole remains stable, thereby ensuring the efficiency of cutting off the burr cutting band on the side of the copper strip.

[0042] The burr removal unit of the copper foil raw material copper strip is arranged between the conveying platform 2 and the guiding platform 3, and is used to remove the burrs and residual burrs on both sides of the copper foil raw material copper strip when the copper foil raw material copper strip is rolled up;

[0043] The burr removal unit of the copper foil raw material copper strip includes a guide inclined plate 5, a first roller 51 is installed at the bottom of the guide inclined plate 5, the first roller 51 is rotatably installed on one side of the top of the winding bin 1, the guide inclined plate 5 is arranged in an arc shape, a smooth cutter 57 is arranged at one end of the guide inclined plate 5, an electric roller 55 is installed on one side of the outside of the winding bin 1, a movable arm 56 is installed on the rotating end of the electric roller 55, a force block 58 is installed on the side of the guide inclined plate 5 close to the smooth cutter 57, a pressure groove 581 is arranged on the surface of the force block 58, a pressure column 59 is arranged on the top of the movable arm 56, and the pressure column 59 is in movably contact with the pressure groove 581.

[0044] In this embodiment, as the guide roller 31 compresses and conveys the upper surface of the copper strip, the copper strip is continuously conveyed by the guide roller 31 and the conveying roller 22 at the same time, and the end of the copper strip is gradually inserted parallel to the upper pressing frame 17 and the lower conveying frame 16. Before inserting the upper pressing frame 17 and the lower conveying frame 16, the burr cutting band removal step of the side edge of the copper strip is performed. By driving the electric roller 55, the electric roller 55 drives the movable arm 56 to rotate close to the side edge area of ​​the copper strip. The movable arm 56 rotates during the rotation process. In the process, the pressure column 59 at the top of the movable arm 56 will squeeze the pressure groove 581 on the surface of the force block 58 during the movement, so that the pressure column 59 pushes the guide inclined plate 5 close to the burr cutting band on the side of the copper strip through the pressure groove 581, so that the smooth cutter 57 at one end of the guide inclined plate 5 is in the cutting area of ​​the burr cutting band on the side of the copper strip. With the continuous transportation of the copper strip, the burr cutting band on the side of the copper strip is cut off, ensuring that the edge section of the copper strip is smooth, thereby increasing the actual use area of ​​the copper strip after processing copper foil.

[0045] The burr grinding unit of the copper foil raw material copper strip is also arranged between the conveying platform 2 and the guiding platform 3, and is used for grinding both sides of the copper foil raw material copper strip when the burrs and residual burrs on both sides of the copper foil raw material copper strip are cut off, so as to improve the smoothness of both sides of the copper foil raw material copper strip;

[0046] The copper foil raw material copper strip burr grinding unit includes an electric grinding roller 561, a movable arm 56 is arranged in an arc shape, and the electric grinding roller 561 is installed at one end of the movable arm 56;

[0047] In this embodiment, during the step of removing the burr cut band on the side of the copper strip, as the movable arm 56 moves closer to the side area of ​​the copper strip, the smooth cutter 57 will remove the burr cut band on the side of the copper strip. Before removing, the electric grinding roller 561 at one end of the movable arm 56 will first contact the burr cut band on the side of the copper strip, and grind and soften the burr cut band in this area, making it easier for the smooth cutter 57 to remove the burr cut band on the side of the copper strip, thereby further improving the efficiency of removing the burr cut band on the side of the copper strip.

[0048] Embodiment 2:

[0049] Based on the first embodiment, the second embodiment takes into account that in the process of removing the burr cutting band on the side of the copper strip, in order to avoid the guide inclined plate 5 and the force block 58 being subjected to excessive pressure from the pressure column 59, resulting in the guide inclined plate 5 being tilted too much, so that the smooth cutter 57 is inserted too deeply into the burr cutting band on the side of the copper strip, resulting in wasteful removal of the side of the copper strip, the second embodiment is provided with a copper strip burr removal limit unit to avoid the above problem;

[0050] A copper strip burr removal limiting unit is provided on one side of the movable arm 56, and the copper strip burr removal limiting unit includes a second roller 521, and the second roller 521 is rotatably installed on one side of the top of the winding bin 1, and an inner groove 53 is provided on one side of the guide inclined plate 5, and a third roller 531 is installed in the inner groove 53, and a limiting rotating plate 52 is sleeved on the rotating end of the third roller 531, and one end of the limiting rotating plate 52 is rotatably sleeved on the rotating end of the second roller 521, and a grinding block 522 is provided on one side of the limiting rotating plate 52;

[0051] In this embodiment, when the guide inclined plate 5 is pushed and offset by the pressure column 59, the limit rotating plate 52 installed in the inner groove 53 on one side of the guide inclined plate 5 will rotate and offset on the third roller 531. As the limit rotating plate 52 continues to rotate, the other end of the limit rotating plate 52 is installed on the top of the winding bin 1 through the second roller 521. When the guide inclined plate 5 is pushed by the pressure column 59 to reach the cutting area, the guide inclined plate 5 will be locked under the pulling of the limit rotating plate 52, thereby limiting the cutting depth of the burr cutting strip on the side of the copper strip. At the same time, the grinding block 522 set on one side of the limit rotating plate 52 will contact grind and polish the side of the copper strip after cutting, so as to avoid waste of cutting on the side of the copper strip, and further increase the actual use area of ​​the copper strip after copper foil processing.

[0052] Working principle: When the device is in use, the copper strip is first placed on the top of the conveying roller 22 on the top of the guide frame 21 on one side of the conveyor platform 2. The conveying roller 22 in this area will convey the copper strip, so that one end of the steel strip is conveyed along the guide frame 21 to the conveying roller 22 on the top of the conveyor platform 2. During the movement of the end of the copper strip, when the end of the copper strip moves between the guide platform 3 and the conveyor platform 2, the guide roller 31 at the bottom of the guide platform 3 will press the upper surface of the copper strip, so that when the burr cutting band on the side of the copper strip is cut off, the copper strip as a whole remains stable, thereby ensuring the efficiency of the cutting band cutting of the burr on the side of the copper strip;

[0053] The copper strip is continuously conveyed by the guide roller 31 and the conveying roller 22 at the same time, and the end of the copper strip will be gradually inserted in parallel between the upper clamping frame 17 and the lower conveying frame 16. Before inserting the upper clamping frame 17 and the lower conveying frame 16, the burr cutting band on the side of the copper strip is removed. By driving the electric roller 55, the electric roller 55 will drive the movable arm 56 to rotate close to the side area of ​​the copper strip. During the rotation of the movable arm 56, the pressure column 59 at the top of the movable arm 56 will squeeze the pressure groove 581 on the surface of the force block 58 during the movement, so that the pressure column 59 pushes the guide inclined plate 5 close to the burr cutting band on the side of the copper strip through the pressure groove 581, so that the smooth cutter 57 at one end of the guide inclined plate 5 is in the removal area of ​​the burr cutting band on the side of the copper strip. With the continuous conveying of the copper strip, the burr cutting band on the side of the copper strip is removed, ensuring that the edge section of the copper strip is smooth, and increasing the actual use area of ​​the copper strip after copper foil processing;

[0054] As the movable arm 56 moves closer to the side area of ​​the copper strip, the smooth cutter 57 will cut off the burr cut band on the side of the copper strip. Before cutting, the electric grinding roller 561 at one end of the movable arm 56 will first contact the burr cut band on the side of the copper strip to grind and soften the burr cut band in this area, making it easier for the smooth cutter 57 to cut off the burr cut band on the side of the copper strip, further improving the efficiency of cutting off the burr cut band on the side of the copper strip.

[0055] When the guide inclined plate 5 is pushed and offset by the pressure column 59, the limit rotating plate 52 installed in the inner groove 53 on one side of the guide inclined plate 5 will rotate and offset on the third roller 531. As the limit rotating plate 52 continues to rotate, the other end of the limit rotating plate 52 is installed on the top of the winding bin 1 through the second roller 521. When the guide inclined plate 5 is pushed and reaches the cutting area by the pressure column 59, the guide inclined plate 5 will be locked under the pulling of the limit rotating plate 52, thereby limiting the cutting depth of the burr cutting strip on the side edge of the copper strip. At the same time, the grinding block 522 arranged on one side of the limit rotating plate 52 will perform contact grinding and polishing on the side edge of the copper strip after cutting, so as to avoid waste of cutting on the side edge of the copper strip and further increase the actual use area of ​​the copper strip after copper foil processing.
