Description

Technical Field

[0001] This utility model relates to a slitting device after electroplating of composite current collectors, belonging to the field of composite current collector electroplating technology. Background Technology

[0002] Composite current collector films are a new type of current collector material with a three-layer composite structure of "metal-polymer material film-metal". They have important applications in fields such as lithium-ion batteries. The preparation method of composite copper current collectors is usually to form a magnetron film by magnetron sputtering a base layer (nickel-chromium alloy) and a conductive copper layer (usually called copper seed layer) on a polymer substrate material (PET / PP / PI, etc.) through roll-to-roll production process. Next, the magnetron film is electroplated to thicken the metal layer to 1 μm, and then subjected to anti-oxidation treatment in an anti-oxidation bath to complete the preparation.

[0003] Current electroplating equipment mainly includes an unwinding device for unwinding the composite copper current collector semi-finished product, a liquid tank for holding the electroplating solution, two rows of parallel clamping devices, and a winding device for winding the composite copper current collector finished product; among which, the clamping device includes a conductive clamp for clamping the composite copper current collector and a transmission system for driving the clamp to move.

[0004] However, existing electroplating equipment has the following problems during the electroplating process:

[0005] The electroplating equipment is designed so that, during electroplating, the conductive clamps on both sides serve as the input points for the current. The electric field lines in the edge areas are more concentrated, resulting in a significantly higher local current density than other areas. The conductive clamps on both sides are also more prone to accumulating a large number of loose metal particles. These loose metal particles are carried into the anti-oxidation tank, causing contamination. They are also easily deposited on the surface of the composite current collector. After being pressed by the rollers, they are squeezed and adhered to the surface, forming embossed marks. As the number of meters of composite current collector wound increases, defects such as annular protrusions and bursting ridges accumulate, thus greatly reducing the yield of composite current collector preparation. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a composite current collector electroplating post-slitting device.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] A composite current collector electroplating and slitting device includes a base, an electroplating tank fixedly connected to one side of the top of the base, an anti-oxidation tank fixedly connected to the other side of the top of the base, an mounting frame that passes through the electroplating tank and the anti-oxidation tank in sequence on the base, the bottom of the mounting frame being fixedly connected to the base, and a conveying mechanism for conveying the film material on the surface of the mounting frame.

[0009] A slitting mechanism for cutting both sides of the film material is provided between the electroplating tank and the anti-oxidation tank;

[0010] The slitting mechanism is equipped with a waste recycling mechanism on one side for winding up the slitting film material.

[0011] By setting a slitting mechanism between the electroplating tank and the anti-oxidation tank, the copper powder accumulation areas on both sides of the film material are cut off, and the cut film material is simultaneously collected by the waste recycling mechanism. This avoids metal particles being brought into the anti-oxidation tank, which would cause the film material to have embossed marks, ring-shaped protrusions, and bursting ridges, thus significantly improving the yield of composite current collector preparation.

[0012] Preferably, the transmission mechanism includes an unwinding roller and a winding roller, the unwinding roller being disposed at one end of the mounting frame near the electroplating tank, and the winding roller being disposed at the other end of the mounting frame near the anti-oxidation tank;

[0013] Both ends of the unwinding roller are rotatably connected to the mounting frame, one end of the winding roller is rotatably connected to the inner side of the mounting frame, and the other end of the winding roller is provided with a first stepper motor. The side wall of the first stepper motor is fixedly connected to the mounting frame, and the output shaft of the first stepper motor is fixedly connected to the end of the winding roller.

[0014] In this solution, the first stepper motor drives the take-up roller to rotate, which works with the unwind roller to form a traction force, driving the film material to move from one end of the mounting frame to the other end. The unwind roller is rotatably connected to the mounting frame to ensure that the film material is released smoothly.

[0015] The winding rollers are precisely controlled by a motor to ensure uniform film conveying speed, providing a stable material conveying foundation for subsequent flattening and slitting processes.

[0016] Preferably, a first flattening mechanism for flattening the film material is provided above the electroplating tank;

[0017] The first flattening mechanism includes a first flattening roller, both ends of which are rotatably connected to the mounting frame;

[0018] The number of the first flattening rollers is set to three, of which two of the first flattening rollers are set above the electroplating tank, and the other first flattening roller is set inside the electroplating tank;

[0019] Three first flattening rollers provide multi-directional support, with two located above the electroplating tank and one inside. The film material passes around these rollers during transport. The contact pressure between the rollers and the film material eliminates wrinkles on the film surface and keeps the film flat during electroplating, preventing uneven current distribution caused by uneven film material and reducing the generation of loose metal particles.

[0020] Preferably, a second flattening mechanism for flattening the membrane material is provided above the antioxidant tank;

[0021] The second flattening mechanism includes a second flattening roller, both ends of which are rotatably connected to the mounting frame;

[0022] The number of the second flattening rollers is set to three, with two of the second flattening rollers positioned above the anti-oxidation tank and the other second flattening roller positioned inside the anti-oxidation tank;

[0023] Three second flattening rollers are respectively arranged above and inside the anti-oxidation tank. Before the membrane material enters the anti-oxidation tank after being slit, it further eliminates slight wrinkles that may have occurred during the slit process by making contact with each flattening roller. This ensures that the membrane material enters the anti-oxidation tank flat, avoids the deposition of metal particles at wrinkles, and guarantees the uniformity of the anti-oxidation treatment.

[0024] Preferably, the slitting mechanism includes a bottom blade roller and a first mounting frame. The bottom blade roller is cylindrical, with both ends of the bottom blade roller passing through the mounting frame. The bottom blade roller is rotatably connected to the mounting frame. An annular groove is formed on the outer periphery of the bottom blade roller. A first through groove is formed at the top and bottom of the annular groove, and a second through groove is formed on both sides of the annular groove. The number of annular grooves is set to two.

[0025] The first mounting frame is located on the side of the bottom blade roller near the electroplating tank. The bottom of the first mounting frame is fixedly connected to the base. Both sides of the first mounting frame are provided with cutting structures, and the two cutting structures are respectively matched with the two ends of the bottom blade roller.

[0026] In this design, the slitting mechanism is centered around a bottom cutter roller and a first mounting frame. The bottom cutter roller is cylindrical, and its outer annular groove provides installation and adjustment space for the moving ring. The first mounting frame fixes the cutting structure, ensuring precise fit between the cutting structure and the bottom cutter roller. During membrane material transport, the bottom cutter roller rotates to support the membrane material, and the two cutting structures correspond to both sides of the membrane material, cutting off the copper powder accumulation area through the cutting action.

[0027] Preferably, the cutting structure includes a moving ring, a filler, a cutting machine, and a locking component. The moving ring has an annular cutting groove on its outer periphery. The moving ring is sleeved on the outer periphery of the annular groove and is slidably connected to the annular groove. A limiting rod is fixedly connected to the inner periphery of the moving ring. The limiting rod passes through two first through slots and is slidably connected to the two first through slots.

[0028] The filler is used to fill the gap between the moving ring and the annular groove. The filler is set as a semi-annular shape. The filler is set as multiple groups, and the number of fillers in each group is set to two. The locking component is used to lock the multiple groups of fillers.

[0029] The cutting machine is positioned above the moving ring and is matched with the annular cutting groove. A lateral moving component is provided between the cutting machine and the first mounting frame. The lateral moving component is used to synchronously adjust the lateral position of the cutting machine and the moving ring.

[0030] In this design, the moving ring is fitted inside the annular groove of the bottom cutter roller. The annular cutting groove on its outer periphery works with the cutting machine to form a scissor effect. This shearing method has a small cutting force, little pulling on the film material, and a neat cut, which greatly reduces the risk of film tearing. The limiting rod passes through the first through groove of the bottom cutter roller, restricting the rotation of the moving ring and allowing only lateral movement to adjust the cutting position.

[0031] The filler is semi-circular, and its transverse thickness is determined according to the required width of the film material to be cut. When the width of the film material to be cut changes, a filler of the corresponding size is selected to fill the gap between the moving ring and the annular groove, ensuring that the surface of the bottom cutter roller remains flat.

[0032] The lateral moving component synchronously adjusts the lateral position of the cutting machine and the moving ring to achieve precise cutting of film materials of different widths.

[0033] Preferably, the locking component includes a rotating ring and a connector. The rotating ring is rotatably connected to the end of the bottom cutter roller. An annular component is fixedly connected to the side wall of the rotating ring. After the annular component rotates at a certain angle relative to the bottom cutter roller, the annular component and the bottom cutter roller are locked by bolts. Two locking rods are fixedly connected to the side wall of the rotating ring. The ends of the two locking rods are fixedly connected to the same rotating disk. The rotating disk is rotatably connected to the inner wall of the bottom cutter roller.

[0034] The number of the plug-in components is set to multiple groups, and the number of the plug-in components in each group is set to two. The ends of the two plug-in components in each group are fixedly connected to the two fillers in each group. The two plug-in components in each group are respectively set through two second through slots. The side walls of the two plug-in components in each group are provided with locking slots. The two locking slots are arranged opposite to each other about the central axis of the bottom knife roller and have opposite opening directions. The locking slots are matched with locking rods.

[0035] In this scheme, once the position of the moving ring is determined, the plug-in connected to the filler is inserted into the bottom cutter roller through the second through groove. The two semi-circular fillers in each group will be combined into a complete circular filler and fill the circular groove, thereby keeping the surface of the bottom cutter roller flat except for the circular cutting groove, thus avoiding wrinkles caused by the film material contacting the uneven bottom cutter roller.

[0036] Then, by rotating the rotating ring, the two locking rods can be driven to rotate synchronously, and the two locking rods will engage with the locking grooves on the surface of the plug-in parts on both sides, thereby locking multiple plug-in parts and their connected fillers at the same time. Finally, the ring part can be fixed to the bottom knife roller by bolts, thereby fixing the rotating ring connected to the ring part.

[0037] Preferably, the lateral moving component includes a first electric push rod, which is fixedly connected to the side wall of the first mounting frame. A movable frame is fixedly connected to the output end of the first electric push rod. First guide rods are provided above and below the first electric push rod. The ends of the two first guide rods are fixedly connected to the movable frame, and the middle parts of the two first guide rods are slidably connected to the first mounting frame.

[0038] A first extension rod is provided between the movable frame and the limiting rod. One end of the first extension rod is rotatably connected to the movable frame, and the other end of the first extension rod is fixedly connected to the limiting rod.

[0039] A second extension rod is provided between the movable frame and the cutting machine. One end of the second extension rod is fixedly connected to the movable frame, and a lifting component is provided between the other end of the second extension rod and the cutting machine.

[0040] In this scheme, the lateral moving component uses the first electric push rod as the power source to drive the moving frame to move laterally; the first guide rod ensures that the moving frame moves smoothly and prevents deviation; the moving frame drives the limiting rod through the first extension rod, thereby pushing the moving ring to move laterally along the bottom cutter roller annular groove.

[0041] Meanwhile, the moving frame drives the cutting machine to move synchronously through the second extension rod, ensuring that the cutting machine is always precisely aligned with the annular cutting groove on the outer circumference of the moving ring, so as to realize the adaptation and adjustment of the cutting position and the width of the film material, and meet the slitting needs of different specifications of film materials.

[0042] Preferably, the lifting component includes a connector, the side wall of the connector is fixedly connected to the end of the second extension rod away from the moving frame, the bottom of the connector is fixedly connected to a second electric push rod, the output end of the second electric push rod is fixedly connected to the cutting machine, the second electric push rod is provided with a second guide rod on both sides, the bottom ends of the two second guide rods are fixedly connected to the cutting machine, and the middle parts of the two second guide rods are slidably connected to the connector.

[0043] In this design, the lifting component is fixed to the end of the second extension rod via a connector. The second electric push rod drives the cutting machine to move up and down, and the second guide rod ensures smooth lifting of the cutting machine. The contact force between the cutting machine and the annular cutting groove of the moving ring is controlled by adjusting the height of the cutting machine.

[0044] Preferably, the waste recycling mechanism includes a second mounting frame, on which a bottom cutter roller is disposed near the anti-oxidation tank. The bottom of the second mounting frame is fixedly connected to the base. A second stepper motor is fixedly connected to the side wall of the second mounting frame. A recycling roller is fixedly connected to the output shaft of the second stepper motor. The end of the recycling roller is rotatably connected to the inner wall of the second mounting frame. A third flattening roller is disposed below the recycling roller. Both ends of the third flattening roller are rotatably connected to the inner wall of the second mounting frame.

[0045] In this design, the waste recycling mechanism uses a second stepper motor to drive the recycling roller to rotate, while a third flattening roller flattens the waste edges generated during slitting. After flattening, the waste edges are simultaneously wound up by the recycling roller, preventing them from scattering and contaminating the equipment or being carried into the anti-oxidation tank.

[0046] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0047] 1. Effectively solves the problem of loose metal particle contamination at the conductive clamp after electroplating of magnetron sputtering film in existing technologies. By setting a cutting mechanism between the electroplating tank and the anti-oxidation tank, the copper powder accumulation area on both sides of the film material is cut by the cooperation of the cutting machine and the annular cutting groove on the outer periphery of the moving ring. The cut film material is simultaneously collected by the waste recycling mechanism to avoid metal particles being brought into the anti-oxidation tank, which would cause the film material to have embossed marks, annular protrusions and bursting, and significantly improve the preparation yield of composite current collectors.

[0048] 2. When adjusting the position of the annular cutting groove on the outer circumference of the bottom cutter roller, there is no need to replace the bottom cutter roller, thus avoiding the problem of needing to readjust the accuracy of the bottom cutter roller during disassembly and installation.

[0098] The workflow of this embodiment is as follows:

[0099] Material conveying start-up: Step motor 23 drives take-up roller 22 to rotate, which works with unwind roller 21 to form traction force, driving the film material to be continuously conveyed from one end of mounting frame 13 to the other end, ensuring uniform film material conveying speed.

[0100] Pre-plating flattening and electroplating: The membrane material first passes through the first flattening mechanism 3. Three first flattening rollers 31 eliminate wrinkles in the membrane material through contact pressure, ensuring that the membrane material enters the electroplating tank 11 flat. In the electroplating tank 11, the membrane material completes the water electroplating process, and the metal layer is thickened to 1um.

[0101] Slitting preparation: Based on the copper powder accumulation width of the conductive clamps on both sides of the film material, the first electric push rod 5671 is used as the power source to drive the moving frame 5672 to move laterally; the first guide rod 5673 ensures that the moving frame 5672 moves smoothly and prevents deviation. The moving frame 5672 drives the limiting rod 566 through the first extension rod 5674, thereby pushing the moving ring 561 to move laterally along the annular groove 53 of the bottom cutter roller 51.

[0102] Meanwhile, the moving frame 5672 drives the cutting machine 563 to move synchronously through the second extension rod 5675, ensuring that the cutting machine 563 is always precisely aligned with the annular cutting groove 565 on the outer periphery of the moving ring 561, so as to realize the adaptation and adjustment of the cutting position and the width of the film material.

[0103] Once the position of the moving ring 561 is determined, the plug 5642 connected to the filler 562 is inserted into the bottom cutter roller 51 through the second through groove 55. The two semi-circular fillers 562 in each group will combine into a complete annular filler 562 and fill the annular groove 53, thereby keeping the surface of the bottom cutter roller 51 flat except for the annular cutting groove 565, thus preventing the film material from wrinkling due to contact with the uneven bottom cutter roller 51.

[0104] Then, by rotating the rotating ring 5641, the two locking rods 5644 can be driven to rotate synchronously, and the two locking rods 5644 will engage with the locking grooves 5646 on the surface of the plug-in parts 5642 on both sides, thereby locking multiple plug-in parts 5642 and the filler parts 562 connected to them at the same time. Finally, the ring part 5643 can be fixed to the bottom knife roller 51 by bolts, thereby fixing the rotating ring 5641 connected to the ring part 5643.

[0105] Finally, the second electric push rod 56762 drives the cutting machine 563 to move downward and inserts the circular blade of the cutting machine 563 into the annular cutting groove 565 to cut the membrane material. The annular cutting groove 565 on its outer periphery cooperates with the cutting machine 563 to form a scissor effect. This shearing method has a small cutting force, a small pulling on the membrane material, and a neat cut, which greatly reduces the risk of membrane material tearing.

[0106] Simultaneous waste recycling: The waste edges generated from slitting enter the waste recycling mechanism 6, are flattened by the third flattening roller 64, and are simultaneously wound up by the recycling roller 63 driven by the second stepper motor 62, so as to avoid the waste edges from scattering and contaminating the equipment or being carried into subsequent processes.

[0107] Flattening and Antioxidant Treatment Before Antioxidation: The cut membrane material enters the second flattening mechanism 4, and three second flattening rollers 41 eliminate the slight wrinkles that may be generated during cutting, ensuring that the membrane material enters the antioxidation tank 12 flat; the membrane material completes the antioxidation treatment in the antioxidation tank 12.

[0108] Finished product winding: The qualified film material after anti-oxidation treatment is wound up by winding roller 22. The whole process realizes the continuous operation of "conveying, flattening, electroplating and cutting, waste recycling, anti-oxidation, and winding", which significantly improves the preparation yield of composite current collectors.

[0109] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
