Description

Technical Field

[0001] The utility model relates to the technical field of copper foil winding and unwinding equipment, in particular to a copper foil coil material feeding mechanism and a vertical winding and unwinding equipment. Background Art

[0002] Electrolytic copper foil is an important material for the manufacture of copper clad laminates (CCLs), printed circuit boards (PCBs), and lithium-ion batteries. Electrolytic copper foil is called the "neural network" for signal and power transmission and communication of electronic products.

[0003] In the related art, after the electrolytic copper foil is unwound or before the electroplated copper foil is rewound, the copper foil cannot be transported to the electroplating station or pulled from the electroplating station to the rewinding and unwinding equipment only by the rewinding and unwinding equipment. Therefore, a corresponding copper foil conveying mechanism needs to be provided. Because the copper foil electroplating process adopts a conveying chain in conjunction with a clamp to vertically hang the long copper foil coil and input or output the copper foil from the electroplating room, that is, the copper foil needs to be in a vertical state (the copper foil is perpendicular to the horizontal plane) during electroplating. In the related art, after the copper foil is rewound and unwound by the horizontal rewinding and unwinding equipment, the horizontal copper foil conveying mechanism is used to unwind and reel the copper foil, and then the copper foil is transported to the electroplating station or the copper foil is pulled from the electroplating station to the rewinding and unwinding equipment, but when the copper foil is unwound and transported to the electroplating station Before electroplating or after the electroplated copper foil is pulled out from the electroplating station, the placement state of the copper foil needs to be converted, that is, the horizontal state and the vertical state need to be converted to match the electroplating of the copper foil in a hanging vertical manner and the horizontal conveying and winding. In this process, the copper foil coil will be bent, causing damage to the copper foil and the electroplating layer, affecting the quality of the electrolytic copper foil; at the same time, the copper foil conveying mechanism in the related technology is not uniform in height with the external electroplating equipment, and the copper foil conveying mechanism cannot be arbitrarily adjusted to be level with the external electroplating equipment. When processing copper foils of different widths, the copper foil conveying mechanism is not level with the electroplating equipment, causing the copper foil to be stuck when it is input into the electroplating equipment, or the height of the copper foil in the electroplating equipment is inconsistent, causing the copper foil to be unable to be completely electroplated.

[0004] There is no effective solution to the problem that the copper foil feeding mechanism in the existing related technology is not able to adjust the height of the external electroplating equipment, cannot meet the requirements of vertical electroplating processing of copper foil, and is easy to damage the copper foil.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0034] See also Figures 1 to 5The embodiment of the present application provides a specific embodiment of a copper foil coil feeding mechanism. The copper foil coil feeding mechanism shown in the figure includes a frame 100. The frame 100 is provided with a plurality of vertically arranged lifting components 200. The plurality of lifting components 200 are transmission-connected to a lifting plate 300. The lifting plate 300 is also connected to the frame 100 through a guide component 400. A vertically arranged feeding unit 500 and a plurality of rollers 600 are provided on the lifting plate 300. The feeding unit 500 is arranged on one side close to the copper foil winding and unwinding station. The plurality of rollers 600 are used to guide the copper foil to be transported along the conveying direction.

[0035] The lifting assembly 200 is used to drive the lifting plate 300 to drive the feeding unit 500 and the roller 600 to move vertically to a preset reference position so that the copper foil (reference Figure 1 The copper foil is electroplated in the process (as shown by the dotted line in the figure).

[0036] In the present embodiment, the conveying direction is determined according to whether the copper foil is unrolled or reeled. When the copper foil coil feeding mechanism is used as a device for feeding the unrolled copper foil to the electroplating station, the conveying direction is from the feeding unit 500 toward the copper foil electroplating station; when the copper foil coil feeding mechanism is used as a device for reeling and unwinding the copper foil after electroplating, the conveying direction is from the copper foil electroplating station toward the feeding unit 500; in the present embodiment, when copper foils of different widths are processed, due to the different reference heights of the external electroplating equipment (satisfying the need to wet the copper foil), the feeding unit 500 and the roller of the copper foil coil feeding mechanism of the present application embodiment need to be adjusted. The height of 600 can be adjusted, so that the coil output from the copper foil coil feeding mechanism of the embodiment of the present application can be smoothly fed to the corresponding electroplating equipment, or when the copper foil coil that has completed electroplating is output from the electroplating equipment, it can smoothly pass through the copper foil coil feeding mechanism and transport the copper foil coil to the corresponding winding and unwinding equipment; in this embodiment, the preset reference position is to ensure that the bottom edge position of the copper foil is always on the same horizontal line when the copper foil passes through the copper foil winding and unwinding equipment, the copper foil coil feeding mechanism and the copper foil electroplating equipment, that is, the copper foil coil feeding mechanism is adjusted to be horizontally aligned with the copper foil electroplating equipment through the lifting component 200, so as to realize the smooth transportation of the copper foil.

[0037] The feeding unit 500 includes a feeding roller 51 and a clamping roller 52 arranged side by side. The clamping roller 52 can be driven to move toward the feeding roller 51 and press the copper foil passing through the feeding unit 500 along the conveying direction against the feeding roller 51. The feeding roller 51 is used to convey the corresponding copper foil along the conveying direction.

[0038] In the present embodiment, the feeding unit 500 is vertically arranged on the lifting plate 300 to meet the needs of transmitting the suspended copper foil; in the present embodiment, the feeding roller 51 provides power to drive the copper foil to be transported along the conveying mode, for example: when the corresponding copper foil is the unwound copper foil, the feeding roller 51 provides power to make the copper foil continue to be transported forward along the conveying direction after being unwound from the winding and unwinding device; when the corresponding copper foil is the copper foil to be wound, the feeding roller 51 provides power to pull the electroplated copper foil to the winding and unwinding device; in the present embodiment, a clamping roller 52 is provided and the clamping roller 52 is driven to move toward the feeding roller 51, so that the copper foil passing through the feeding unit 500 is pressed against the feeding roller 51, and the adhesion of the copper foil to the feeding roller 51 is strengthened, so that when the feeding roller 51 rotates, the copper foil can be driven and transported along the conveying mode, thereby avoiding the copper foil from being unable to be transported due to the small friction with the feeding roller 51 during the transmission process.

[0039] In the above-mentioned copper foil coil feeding mechanism, a lifting component 200 is set and the lifting plate 300 is driven by the lifting component 200 to drive the feeding unit 500 and the roller 600 to move vertically to a preset reference position, so that the copper foil coil feeding mechanism and the external electroplating equipment always maintain the same horizontal height, and the copper foil transported along the conveying direction can smoothly pass through the copper foil electroplating station. At the same time, the height of the copper foil in the electroplating equipment can be made consistent to ensure the quality of copper foil electroplating. The copper foil coil feeding mechanism of the embodiment of the present application can adapt to the feeding of copper foils of different widths; furthermore, the embodiment of the present application conveys the copper foil in a vertical state through the vertically arranged feeding unit 500 and the roller 600, without the need to convert the state of the copper foil, thereby reducing damage to the copper foil and the electroplating layer, and the quality of the electrolytic copper foil is good, which solves the problem that the copper foil feeding mechanism in the related art and the external electroplating equipment are not adjustable in adaptation height, and cannot meet the vertical electroplating processing of the copper foil, and the copper foil is easily damaged.

[0040] In order to adapt the copper foil to the reeling and unreeling and avoid the copper foil being over-pulled or untimely conveyed to cause the copper foil to wrinkle, in some embodiments, reference is made to Figures 1 to 4The lifting plate 300 is also provided with a copper foil conveying tension detection unit 700, which is symmetrically arranged with the feeding unit 500 and is arranged on one side close to the copper foil electroplating station. The copper foil conveying tension detection unit 700 includes a mounting seat 71, a support plate 72, a vertical guide assembly 73, a sliding frame 74, a transmission unit 75, a transverse guide assembly 76 and a buffer roller 77. The mounting seat 71 is connected to the lifting plate 300 through an optical axis 78. The support plate 72 is fixed on the mounting seat 71. Two vertical guide assemblies 73 that are arranged laterally at intervals and extend vertically are arranged on the support plate 72. The sliding frame 74 is connected to the vertical guide assembly 73 and is transmission-connected to the transmission unit 75 arranged between the two vertical guide assemblies 73. The sliding frame 74 is also movably connected to the corresponding optical axis 78 through a shaft sleeve 79. The bottom and top ends of the sliding frame 74 are respectively provided with transversely extending transverse guide assemblies 76, and the two transverse guide assemblies 76 are connected to the vertically arranged buffer roller 77, wherein,

[0041] In this embodiment, any vertical guide assembly 73 that is capable of guiding the vertical movement of the sliding frame 74 is suitable for the vertical guide assembly 73 of the embodiment of the present application. For example, the vertical guide assembly 73 may be a linear guide rail.

[0042] In this embodiment, any transmission unit 75 that can provide vertical movement of the power transmission slide frame 74 is suitable for the transmission unit 75 of the embodiment of the present application. For example, the transmission unit 75 can be an electric cylinder or a linear motor.

[0043] The transmission unit 75 is used to drive the sliding frame 74 to slide vertically along the vertical guide assembly 73 and the optical axis 78, and drive the transverse guide assembly 76 and the buffer roller 77 to move vertically so that the horizontal plane where the center of gravity of the buffer roller 77 is located is aligned with the horizontal center line of the copper foil transported along the conveying mode.

[0044] In this embodiment, the buffer roller 77 is installed on the sliding frame 74 through two upper and lower lateral guide components 76, and the buffer roller 77 will move in the lateral direction when it is pulled by the conveyed copper foil. In order to enable the buffer roller 77 to move smoothly in the lateral direction, it is necessary to make the upper and lower ends of the axial direction of the buffer roller 77 be evenly stressed. Therefore, it is necessary to adjust the horizontal plane where the center of gravity of the buffer roller 77 is located to be flush with the horizontal center line of the copper foil. In this way, when the copper foil bypasses the buffer roller 77, in the vertical direction, the contact area of ​​the buffer roller 77 with the copper foil is equal, and the buffer roller 77 is evenly stressed in its axial direction (vertical direction). When the buffer roller 77 is pulled by the copper foil, it will move smoothly in the lateral direction to avoid the buffer roller 77 tilting in the vertical plane due to uneven upper and lower forces, and the lateral movement of the buffer roller 77 is blocked.

[0045] The buffer roller 77 slides laterally along with the lateral guide assembly 76 when being pulled by the copper foil conveyed in the conveying direction.

[0046] In this embodiment, the buffer roller 77 will move in the lateral direction when being pulled by the conveyed copper foil. For example, when the speed at which the electroplating equipment pulls the copper foil is greater than the speed at which the reeling and unreeling equipment and the feed unit 500 convey the copper foil, the copper foil will be over-pulled. At this time, the buffer roller 77 will be pulled and move forward in the current conveying direction. By detecting the lateral displacement of the buffer roller 77, it can be determined that the reeling and unreeling and conveying of the copper foil need to be accelerated, that is, the reeling and unreeling and conveying speeds need to be increased.

[0047] The feeding unit 500 slows down or speeds up the conveyance of the copper foil according to the lateral sliding direction of the buffer roller 77 .

[0048] In this embodiment, by judging the direction and distance of the lateral movement of the buffer roller 77, it can be judged whether the winding, unwinding and conveying of the copper foil needs to be accelerated or slowed down. It can be understood that in this embodiment, a corresponding position detection device (for example, a position detection sensor) is set beside the buffer roller 77 to check the position of the buffer roller 77 after movement, and compare it with its initial position or the position detected last time, so as to determine the direction of movement and the displacement of the buffer roller 77. It can be understood and should be understood that after determining the moving direction of the buffer roller 77, it can be determined whether the winding, unwinding and conveying of the copper foil is slowed down or accelerated, and by determining the displacement of the buffer roller 77, the degree of slowing down or acceleration can be determined, that is, the amount that needs to be changed. Of course, in this embodiment, the adjustment amount of changing the winding, unwinding and conveying of the copper foil by detecting the moving position of the buffer roller 77 is a rough change, and multiple adjustments are performed to achieve matching of the speed of the feeding unit 500 conveying the copper foil with the speed of the copper foil winding and unwinding and the speed of the electroplating equipment pulling the copper foil.

[0049] It can be understood that, in such an arrangement, by setting up the copper foil conveying tension and relaxation detection unit 700, and by the transmission unit 75 transmitting the sliding frame 74 to drive the lateral guide assembly 76 and the buffer roller 77 to move vertically, so that the horizontal plane where the center of gravity of the buffer roller 77 is located is aligned with the horizontal center line of the copper foil conveyed along the conveying mode, so that the buffer roller 77 is subjected to uniform force when the copper foil is pulled, and the buffer roller 77 can move smoothly, and then accurately determine whether it is necessary to adjust the winding and unwinding speed of the copper foil and the conveying speed, so as to avoid the copper foil being damaged by excessive pulling, or the copper foil being wrinkled due to too slow transmission, which affects the quality of the electrolytic copper foil.

[0050] In order to realize the installation of the buffer roller 77 and the transverse guide assembly 76, in some optional embodiments, the sliding frame 74 includes a lower slide plate 742 and an upper slide plate 743 connected by a connecting rod 741, the lower slide plate 742 is connected to the two vertical guide assemblies 73 and the transmission unit 75, and shaft sleeves 79 are provided at both lateral ends of the lower slide plate 742 and the upper slide plate 743, and the shaft sleeves 79 are sleeved on the corresponding optical axis 78 to enable the sliding frame 74 to be movably connected to the optical axis 78, and a transverse guide assembly 76 is respectively provided on the lower slide plate 742 and the upper slide plate 743.

[0051] To achieve the lateral movement of the buffer roller 77, in some embodiments, reference is made to Figures 1 to 5 The lateral guide assembly 76 includes a mounting block 761, a line spindle 762, a bearing box slider 763 and a return spring 764. The line spindle 762 is connected to the lower slide 742 or the upper slide 743 through the mounting blocks 761 arranged at both ends of its axial direction. The line spindle 762 is provided with a bearing box slider 763 that can slide axially along the line spindle 762. A return spring 764 is provided on both lateral sides of the bearing box slider 763 on the line spindle 762. One free end of the return spring 764 is connected to the bearing box slider 763, and the other free end movably abuts against the corresponding mounting block 761. The buffer roller 77 is respectively connected to the lower slide 742 and the upper slide 743 through the guide shaft supports 765 arranged at both ends of its axial direction.

[0052] When the buffer roller 77 is pulled by the copper foil conveyed along the conveying direction, the bearing box type slider 763 slides axially along the wire spindle 762 and drives the buffer roller 77 to move laterally.

[0053] The return spring 764 is used to buffer the bearing box slider 763 from sliding along the line spindle 762 so that the buffer roller 77 can move smoothly laterally, and to drive the bearing box slider 763 to return and move along the line spindle 762 after the feeding unit 500 slows down or accelerates the conveying of the copper foil.

[0054] In this embodiment, when the buffer roller 77 is pulled by the copper foil and moves laterally, the bearing box slider 763 will follow the movement. At this time, the return spring 764 is compressed to generate a corresponding elastic force to buffer the lateral sliding of the bearing box slider 763, so as to prevent the bearing box slider 763 from hitting the mounting block 761 when the copper foil is suddenly accelerated. When the moving direction and moving position of the buffer roller 77 are detected and the conveying of the copper foil is slowed down or accelerated, the force previously applied to the buffer roller 77 will be released. At this time, the buffer roller 77 moves and resets in the direction opposite to the previous moving direction under the action of the elastic force released by the compressed return spring 764.

[0055] To achieve the installation of the feed roller 51 and the clamping roller 52, in some optional embodiments, the lifting plate 300 is connected to the upper base plate 54 through a connecting column 53, and the feed roller 51 is connected to the lifting plate 300 and the upper base plate 54 through a first flange seat 55. After one axial end of the feed roller 51 passes through the lifting plate 300 and comes out, it is connected to the feed drive motor 57 through a coupling 56.
