Description

Technical Field

[0001] This application relates to the field of copper foil production, and in particular to an ultra-thick copper foil foil making machine. Background Art

[0002] Copper foil is a kind of cathode electrolytic material, a thin and continuous metal foil deposited on the base layer of a circuit board, which serves as the conductor of a PCB; with the development of the electronics industry, copper foil, as a key material, has an increasing demand and gradually more performance requirements. Ultra-thick copper foil is a variety produced due to special performance requirements, which has good electrical and thermal conductivity while also having a mechanical support function.

[0003] In traditional copper foil production, the copper foil strip is fed into the foil making machine, and the copper foil strip shuttles up and down between several guide rollers to roll and adjust the thickness of the copper foil strip. After rolling, the copper foil is wound up to complete the processing of the copper foil; however, the ultra-thick copper foil has a large thickness, and the force exerted on the guide rollers by rolling the copper foil through the up-and-down shuttling guide rollers is relatively large, which easily causes damage to the guide rollers. Summary of the Invention

[0004] In order to reduce the probability of production equipment damage in copper foil production, this application provides an ultra-thick copper foil foil making machine.

[0005] The ultra-thick copper foil foil making machine provided by this application adopts the following technical solution: An ultra-thick copper foil foil making machine includes a machine body. At both ends in the length direction of the machine body, an unwinding roller and a winding roller are respectively rotatably arranged. Between the unwinding roller and the winding roller of the machine body, several groups of rolling assemblies are arranged. Each rolling assembly includes an upper pressing block, a lower pressing block, an upper pressing roller and a lower pressing roller. The upper pressing block and the lower pressing block are both slidably arranged on the machine body. The upper pressing roller is rotatably arranged on the upper pressing block, and the lower pressing roller is rotatably arranged on the lower pressing block. The upper pressing roller is located directly above the lower pressing roller. The upper pressing block and the lower pressing block slide to adjust the gap between the upper pressing roller and the lower pressing roller. The gap between the upper pressing rollers and the lower pressing rollers of several groups of rolling assemblies gradually increases from the end close to the unwinding roller to the end far from the unwinding roller.

[0006] By adopting the above technical solution, the upper pressing roller and the lower pressing roller are used to roll and produce ultra-thick copper foil. Compared with the method of threading the ultra-thick copper foil through the guiding rollers above and below for rolling, the rolling method of the upper pressing roller and the lower pressing roller against each other can reduce the force exerted by the ultra-thick copper foil on the roller pair, thereby reducing the probability of the copper foil production damaging the production equipment. The upper pressing roller and the lower pressing roller with a sliding function can be adjusted according to the required thickness of the copper foil, gradually rolling the copper foil to the required thickness, reducing the workload of each rolling component and the reaction force received, and further reducing the probability of the copper foil production damaging the production equipment. The overall height between multiple rolling components can be adjusted, so that the multiple rolling components are arranged in an arc shape as a whole, making the copper foil during rolling arranged in an arc surface, reducing the probability of the copper foil breaking during rolling.

[0007] Optionally, a driving mechanism is provided between the machine body and the rolling component. The driving mechanism includes a first lead screw and a second lead screw. Both the first lead screw and the second lead screw are rotatably arranged on the machine body. The first lead screw is threadedly connected to the upper pressing block, and the second lead screw is threadedly connected to the lower pressing block.

[0008] By adopting the above technical solution, by driving the upper pressing block and the lower pressing block respectively by the first lead screw and the second lead screw, it is convenient to adjust the distance between the upper pressing roller and the lower pressing roller and the overall height between the upper pressing roller and the lower pressing roller.

[0009] Optionally, synchronous gears are provided on both the first lead screw and the second lead screw. The two synchronous gears are respectively slidably arranged on the first lead screw and the second lead screw, and the two synchronous gears are engaged and separated from each other by sliding.

[0010] By adopting the above technical solution, when the synchronous gears are engaged with each other, one of the lead screws can be rotated to drive the other lead screw, thereby realizing the synchronous rotation of the first lead screw and the second lead screw, and thus realizing the synchronous lifting of the upper pressing roller and the lower pressing roller.

[0011] Optionally, synchronous belt wheels are installed at the bottoms of both the first lead screw and the second lead screw, and a synchronous belt is detachably sleeved on the synchronous belt wheels.

[0012] By adopting the above technical solution, the setting of the synchronous belt wheels can realize the synchronous lifting of the upper pressing block or the lower pressing block on both sides in the width direction of the machine body by installing the synchronous belt, and can also drive the synchronous lifting of multiple rolling components.

[0013] Optionally, a driving motor is installed on the upper pressing block. The driving motor is connected to the upper pressing roller. A driving gear is fixedly provided at one end of the upper pressing roller away from the connection with the driving motor. A driven gear is fixedly provided on the lower pressing roller corresponding to the driving gear, and the driven gear meshes with the driving gear.

[0014] By adopting the above technical solution, the driving motor drives the upper pressing roller to rotate, and the lower pressing roller is synchronously rotated through the driving gear and the driven gear. The rotation directions of the upper pressing roller and the lower pressing roller are different, and the pressing effect is improved by the counter-rolling of the upper pressing roller and the lower pressing roller.

[0015] Optionally, a trimming component is arranged between the pressing component and the winding roller. The trimming component includes a mounting rod, a mounting ring and a cutter. The mounting rod is fixedly arranged on the machine body. The mounting ring is slidably arranged on the mounting rod, and the mounting ring slides along the width direction of the machine body. The cutter is mounted on the mounting ring, and the cutting edge of the cutter faces the pressing component.

[0016] By adopting the above technical solution, the trimming component can trim the two ends in the width direction of the copper foil after pressing, cut off the edges of the copper foil that become wider due to pressing, and realize the trimming of the copper foil.

[0017] Optionally, a guiding roller is rotatably arranged on one side of the trimming component facing the pressing component, and the height of the guiding roller is lower than that of the cutter.

[0018] By adopting the above technical solution, the copper foil is adjusted to the cutter through the guiding roller, which is convenient for the cutter to cut.

[0019] Optionally, a deviation rectifying roller is rotatably arranged on one side of the trimming component facing the winding roller. Guide rings are sleeved at both ends in the length direction of the deviation rectifying roller, and the guide rings slide along the length direction of the deviation rectifying roller.

[0020] By adopting the above technical solution, the trimmed copper foil is guided to the center of the deviation rectifying roller through the guide ring, reducing the probability that the copper foil slides during winding and causes the copper foil to be randomly stacked on the winding roller, thus facilitating the winding of the winding roller.

[0021] Optionally, a cutting-off knife is arranged on one side of the deviation rectifying roller facing the winding roller, and the cutting-off knife is slidably arranged on the machine body along the width direction of the machine body.

[0022] By adopting the above technical solution, the cutting-off knife can cut off the copper foil when the winding roller needs to be replaced, which is convenient for the replacement of the winding roller.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. By using an upper pressure roller and a lower pressure roller to roll and produce an ultra-thick copper foil, compared with the method of threading the ultra-thick copper foil through guide rollers for rolling, the rolling method of the upper pressure roller and the lower pressure roller can reduce the force exerted by the ultra-thick copper foil on the roller pair, thereby reducing the probability of copper foil production damaging production equipment. The upper pressure roller and the lower pressure roller with a sliding function can be adjusted according to the required thickness of the copper foil, gradually rolling the copper foil to the required thickness, reducing the workload of each rolling component and the reaction force received, and further reducing the probability of copper foil production damaging production equipment. The overall height between multiple rolling components can be adjusted, so that multiple rolling components are arranged in an arc shape as a whole, making the copper foil during rolling be arranged in an arc surface, reducing the probability of the copper foil breaking during rolling; 2. By driving the upper pressure block and the lower pressure block respectively through the first lead screw and the second lead screw, it is convenient to adjust the distance between the upper pressure roller and the lower pressure roller and the overall height between the upper pressure roller and the lower pressure roller; 3. When the synchronous gears mesh with each other, one of the lead screws can be rotated to drive the other lead screw, thereby realizing the synchronous rotation of the first lead screw and the second lead screw, and then realizing the synchronous lifting of the upper pressure roller and the lower pressure roller. The setting of the synchronous belt wheels can realize the synchronous lifting of the upper pressure blocks or the lower pressure blocks on both sides in the width direction of the machine body by installing a synchronous belt, and can also drive the synchronous lifting of multiple rolling components; 4. The driving motor drives the upper pressure roller to rotate, and the synchronous rotation of the lower pressure roller is realized through the driving gear and the driven gear.

[0030] The following further elaborates on this application in conjunction with the Figures 1-5 accompanying drawings.

[0031] First of all, it should be noted here that: in the description of this application, when terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and other orientation terms appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings.

Additionally, in this application, unless otherwise clearly specified and limited, when terms such as "installation", "connection", "coupling" appear, they should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, an interference fit, a transition fit and other limiting connections, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium; therefore, for those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] An embodiment of this application discloses an ultra-thick copper foil raw foil machine. Refer to Figure 1, including a machine body 1 that is generally rectangular parallelepiped-shaped. At both ends of the machine body 1 in the length direction, an unwinding roller 2 and a winding roller 3 are rotatably provided respectively. Between the unwinding roller 2 and the winding roller 3 of the machine body 1, a number of rolling components 4 are provided. The rolling component 4 includes an upper pressing block 41, a lower pressing block 42, an upper pressing roller 43 and a lower pressing roller 44. Both the upper pressing block 41 and the lower pressing block 42 are slidably provided on the machine body 1. Each group of rolling components 4 has two upper pressing blocks 41 and two lower pressing blocks 42. One upper pressing block 41 and one lower pressing block 42 form a pair. Two pairs of upper pressing blocks 41 and lower pressing blocks 42 are respectively provided on both sides of the machine body 1 in the width direction. The upper pressing roller 43 is rotatably provided on the upper pressing block 41. Both ends of the upper pressing roller 43 in the length direction are rotatably connected to the two upper pressing blocks 41 respectively. The lower pressing roller 44 is rotatably provided on the lower pressing block 42. Both ends of the lower pressing roller 44 in the length direction are rotatably connected to the two lower pressing blocks 42 respectively. The upper pressing roller 43 is located directly above the lower pressing roller 44. The upper pressing block 41 and the lower pressing block 42 slidably adjust the gap between the upper pressing roller 43 and the lower pressing roller 44. The gap between the upper pressing rollers 43 and the lower pressing rollers 44 of a number of rolling components 4 gradually increases from the end close to the unwinding roller 2 to the end far from the unwinding roller 2. By using the upper pressing roller 43 and the lower pressing roller 44 to roll and produce the ultra-thick copper foil, compared with the ultra-thick copper foil passing through the guiding rollers 14 up and down for rolling, the rolling method of the upper pressing roller 43 and the lower pressing roller 44 rolling against each other can reduce the force exerted by the ultra-thick copper foil on the roller pair, thereby reducing the probability of the copper foil production damaging the production equipment. The upper pressing roller 43 and the lower pressing roller 44 with a sliding function can be adjusted according to the required thickness of the copper foil, gradually rolling the copper foil to the required thickness, reducing the workload of each group of rolling components 4 and the reaction force received, and further reducing the probability of the copper foil production damaging the production equipment. The overall height between multiple groups of rolling components 4 can be adjusted, so that multiple groups of rolling components 4 are arranged in an arc shape as a whole, making the copper foil during rolling be arranged in an arc surface, reducing the probability of the copper foil breaking during rolling.

[0033] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, a driving mechanism 5 is provided between the machine body 1 and the rolling component 4. The driving mechanism 5 includes a first lead screw 51 and a second lead screw 52. The first lead screw 51 and the second lead screw 52 are both rotatably arranged on the machine body 1. The first lead screw 51 is threadedly connected to the upper pressing block 41 and penetrates through the lower pressing block 42. The second lead screw 52 is threadedly connected to the lower pressing block 42 and penetrates through the upper pressing block 41. By driving the upper pressing block 41 and the lower pressing block 42 respectively with the first lead screw 51 and the second lead screw 52, it is convenient to adjust the distance between the upper pressing roller 43 and the lower pressing roller 44 and the overall height between the upper pressing roller 43 and the lower pressing roller 44; the tops of the first lead screw 51 and the second lead screw 52 are polygonal. In this embodiment, the tops of the first lead screw 51 and the second lead screw 52 are quadrilateral. Synchronous gears 6 are sleeved on the tops of the first lead screw 51 and the second lead screw 52 respectively. The two synchronous gears 6 are respectively slidably arranged on the first lead screw 51 and the second lead screw 52. A fixing ring 7 is fixed on the synchronous gear 6. A fixing bolt is threadedly connected to the fixing ring 7. The fixing bolt penetrates through the fixing ring 7 and abuts against the side wall of the top of the first lead screw 51 or the second lead screw 52. Tightening the fixing bolt fixes the synchronous gear 6, and loosening the fixing bolt can slide the synchronous gear 6. The two synchronous gears 6 are meshed and separated from each other by sliding. When the two synchronous gears 6 are meshed with each other, rotating one of the lead screws can drive the other lead screw to rotate synchronously, so as to realize the synchronous lifting of the upper pressing roller 43 and the lower pressing roller 44. The synchronous gear 6 can be used as a rotating handle to manually adjust the height of the upper pressing roller 43 and the lower pressing roller 44, or the height of the upper pressing roller 43 and the lower pressing roller 44 can also be adjusted by installing a motor for electric drive; Synchronous belt wheels 8 are installed at the bottoms of the first lead screw 51 and the second lead screw 52 respectively. A synchronous belt 9 is detachably sleeved on the synchronous belt wheels 8. By sleeving the synchronous belt 9 between the lead screws at both ends in the width direction of the same group of rolling components 4, the synchronous lifting of the upper pressing block 41 or the lower pressing block 42 of the same group of rolling components 4 can be synchronously driven, making the lifting of the upper pressing roller 43 or the lower pressing roller 44 smoother. At the same time, cooperating with the synchronous gear 6 can drive the synchronous lifting of all the upper pressing blocks 41 and the lower pressing blocks 42 of the same group of rolling components 4; By sleeving the synchronous belt 9 between different groups of lead screws, the synchronous lifting of the upper pressing blocks 41 or the lower pressing blocks 42 of multiple groups of rolling components 4 can be synchronously driven. Cooperating with the synchronous gear 6 can also drive the synchronous lifting of all the upper pressing blocks 41 and the lower pressing blocks 42 of multiple groups of rolling components 4.

[0034] Refer to Figure 1 and Figure 3, a driving motor 10 is installed on the upper pressing block 41. The driving motor 10 is connected to the upper pressing roller 43. A driving gear 11 is fixedly provided at one end of the upper pressing roller 43 away from the connection with the driving motor 10. A driven gear 12 is fixedly provided on the lower pressing roller 44 corresponding to the driving gear 11. The driven gear 12 meshes with the driving gear 11. The driving motor 10 drives the upper pressing roller 43 to rotate, and the synchronous rotation of the lower pressing roller 44 is realized through the driving gear 11 and the driven gear 12. The rotation directions of the upper pressing roller 43 and the lower pressing roller 44 are different, and the rolling effect is improved through the counter-rolling of the upper pressing roller 43 and the lower pressing roller 44.

[0035] Refer to Figure 1 and Figure 5 , a trimming component 13 is arranged between the rolling component 4 and the winding roller 3. The trimming component 13 includes a mounting rod 131 fixedly provided on the machine body 1, a mounting ring 132 slidably arranged on the mounting rod 131, and a cutting knife 133 mounted on the mounting ring 132. The two ends of the mounting rod 131 in the length direction are respectively fixedly provided at the two ends of the machine body 1 in the width direction. The mounting ring 132 is fixed on the mounting rod 131 through bolts. By loosening the bolts, the mounting ring 132 can slide along the width direction of the machine body 1. The cutting edge of the cutting knife 133 is arranged towards the rolling component 4. The cutting knife 133 is mounted on the mounting ring 132 through bolts. By loosening the bolts, the cutting angle of the cutting knife 133 on the mounting ring 132 can be adjusted. The trimming component can trim the two ends of the copper foil in the width direction after rolling, cut off the widened edges of the copper foil due to rolling, and realize the trimming of the copper foil; a guiding roller 14 is rotatably arranged on one side of the trimming component 13 facing the rolling component 4. The height of the guiding roller 14 is lower than the height of the cutting knife 133. The copper foil is adjusted to the position of the cutting knife 133 through the guiding roller 14, which is convenient for the cutting of the cutting knife 133.

[0036] Refer to Figure 1 and Figure 5 , a deviation rectifying roller 15 is rotatably arranged on one side of the trimming component 13 facing the winding roller 3. Guide rings 16 are sleeved at both ends of the deviation rectifying roller 15 in the length direction. The guide rings 16 slide along the length direction of the deviation rectifying roller 15. A guide sleeve 19 is fixedly provided on the guide rings 16. Bolts are installed on the guide sleeve 19. By tightening the bolts, the guide rings 16 are fixed on the deviation rectifying roller 15. By loosening the bolts, the guide rings 16 can slide on the deviation rectifying roller 15. The trimmed copper foil is guided to the center of the deviation rectifying roller 15 through the guide rings 16, reducing the probability that the copper foil slides during winding and causes the copper foil to be randomly stacked on the winding roller 3, thus facilitating the winding of the winding roller 3; a cutting knife 17 is arranged on one side of the deviation rectifying roller 15 facing the winding roller 3. The cutting knife 17 is slidably arranged on the machine body 1 along the width direction of the machine body 1. In this embodiment, the cutting knife 17 is installed on a rodless electric cylinder 18. The cutting knife 17 is driven to slide through the rodless electric cylinder 18. The cutting knife 17 can cut off the copper foil when the winding roller 3 needs to be replaced, facilitating the replacement of the winding roller 3.

[0037] The implementation principle of the embodiments of this application is as follows: Install the copper foil strip to be unrolled on the unrolling roller 2, then install the unrolling roller 2 on the machine body 1, install the empty winding roller 3 on the machine body 1, adjust the spacing between all the upper pressing rollers 43 and the lower pressing rollers 44 according to the required copper foil thickness, and at the same time adjust the height of each group of rolling components 4 according to the required copper foil strip thickness to form an arc between the rolling components 4. Pass the copper foil strip to be rolled through all the rolling components 4 in sequence, then guide it through the guide roller 14 and enter the edge trimming component 13 for edge trimming. After edge trimming, it is corrected by the deviation correction roller 15 and then wound onto the winding roller 3. When the winding roller 3 winds a large amount of copper foil, cut the copper foil with the cutting knife 17, replace the winding roller 3, and continue winding.
