Description

Technical Field

[0001] This utility model relates to the technical field of electroplating clamping devices, specifically a composite copper current collector electroplating clamping device. Background Technology

[0002] Composite copper current collectors are typically thickened by electroplating. During the electroplating clamping process, both conductive layers on both sides of the film need to be connected to cathode electrodes. When testing the electrical performance of the current collector film, the conductivity allows for convenient application of test voltage and measurement of current to evaluate the conductivity and other quality indicators of the current collector film.

[0003] Existing current collector electroplating equipment often lacks a buffer device in its clamping assembly, directly and rigidly squeezing the current collector when applying clamping force. This makes the copper layer on the current collector surface easily scratched. For current collectors with a composite thin film substrate, the thin film substrate also faces the risk of damage. Some existing clamping assemblies have defects in conducting conductivity to the current collector film, failing to ensure stable conductivity. After prolonged use, the conductivity of the clamping assembly itself may decline, but there is a lack of effective monitoring and maintenance mechanisms to detect and resolve the problem in a timely manner, affecting the processing quality of the current collector film. To address the shortcomings of existing technologies, we propose a composite copper current collector electroplating clamping device to solve the above problems. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0024] This utility model discloses a composite copper current collector electroplating clamping device.

[0025] According to the appendix Figure 1-6As shown, the device includes a first clamping arm 1 and a second clamping arm 2. A first clamping part 101 and a second clamping part 201 are fixedly connected to one side of the bottom end of the first clamping arm 1 and the second clamping arm 2, respectively. This assembly forms a clamping assembly. When the clamping assembly is installed with the electroplating device, it can clamp the current collector film. The second clamping arm 2 is slidably connected to the outer wall of the first clamping arm 1 through the cooperation of an adjusting component 3. A first conductive plate 4 and a second conductive plate 5 are respectively provided on the opposite surfaces of the first clamping part 101 and the second clamping part 201. An mounting assembly 6 is provided on the first clamping part 101 and the second clamping part 201, fixing the first conductive plate 4 and the second conductive plate 5 to the first clamping part 101 and the second clamping part 201, respectively. This allows for the clamping of the current collector film. Previously, the two clamping parts were in a state of being far apart from each other. By placing the edge of the current collector film between the two clamping parts, with the cooperation of the adjusting component 3, the second clamping part 201 can be driven to move closer to the first clamping part 101, so that the two clamping parts can clamp the current collector film. During the clamping and conveying process, the two sets of conductive plates are respectively attached to the two sides of the current collector to conduct electricity to the current collector film. When the current collector film is subjected to surface treatment processes such as electroplating and chemical plating, the conductivity of the conductive plates can enable the current collector film to participate in the electrochemical reaction as an electrode, thereby forming the required coating on its surface. In addition, when the current collector film is tested for electrical performance, the conductivity of the conductive plates can conveniently apply test voltage and measure current to evaluate the conductivity and other quality indicators of the current collector film.

[0026] The bottom of the second clamping part 201 is provided with a buffer component 8, which has the function of protecting the composite tube film. During the clamping of the conductive material, by setting a buffer spring 802 on the top of the second conductive plate 5, and with the cooperation of the adjusting component 3, sufficient clamping force is provided while reducing hard extrusion on the surface of the current collector, so as to avoid scratching the copper layer or damaging the film substrate.

[0027] Adjustment component 3 includes a rotary motor 301, a drive component 302, and a transmission screw 303. The rotary motor 301 is fixedly mounted on the top of the first clamping arm 1, and the transmission screw 303 is rotatably connected inside the first clamping arm 1. By starting the rotary motor 301, the transmission screw 303 is driven to rotate inside the first clamping arm 1, thereby enabling the drive component 302 to drive the second clamping arm 2 to slide on the outer wall of the first clamping arm 1. This allows adjustment of the distance between the two clamping parts, enabling clamping of current collector films of different thicknesses. The output end of the rotary motor 301 is fixedly connected to the transmission screw 303, and the drive component 302... 02 is slidably sleeved on the outer peripheral wall of the transmission screw 303. The driving component 302 is fixedly connected to the second clamping arm 2. Under long-term use, during the clamping and conduction of the current collector, friction may occur between the two sets of conductive plates and the current collector and other related components. Long-term friction will cause the material on the surface of the conductive plate to gradually wear down, increasing the surface roughness and contact resistance. This will not only affect the conductivity but may also cause local heating, further accelerating the aging and damage of the material. Therefore, it is necessary to disassemble and replace the two sets of conductive plates in a timely manner to ensure the performance of the conductive plates.

[0028] Mounting assembly 6 includes a first mounting plate 601, a first limiting plate 602, a second limiting plate 603, a second mounting plate 604, a connecting cylinder 605, and a connecting plate 606. The first conductive plate 4 and the second conductive plate 5 are respectively fixedly mounted on the end faces of the first mounting plate 601 and the second mounting plate 604. When disassembling and replacing the two sets of conductive plates, firstly, multiple sets of locking bolts 7 are removed from the inside of the first limiting plate 602 and the two sets of mounting plates, and the mounting plates and the two sets of clamping parts are no longer locked. Then, the first mounting plate 601 is pulled to one side, which can simultaneously disassemble the two sets of conductive plates from the end faces of the clamping parts, thereby improving the convenience of disassembling and assembling the two sets of conductive plates, allowing for timely replacement of the conductive plates, and improving the conductivity of the conductive plates.

[0029] The buffer assembly 8 includes a fixed plate 801 and a buffer spring 802. The buffer spring 802 is fixedly installed inside the second clamping part 201. The fixed plate 801 is fixedly installed at the bottom of the buffer spring 802. The first limiting plate 602 is fixedly installed on the outer wall of the fixed plate 801 and the first clamping part 101. The second limiting plate 603 is fixedly installed on the top of the first clamping part 101. The first mounting plate 601 is installed between the first limiting plate 602 and the second limiting plate 603. With the cooperation of the adjusting assembly 3, when the second clamping part 201 is driven to approach the first clamping part 101, the connecting plate 606 at the second mounting plate 604 is slidably connected to the inside of the connecting cylinder 605 at the first mounting plate 601. While ensuring the connection of the two sets of mounting plates, it does not affect the adjustment of the distance between the two sets of mounting plates, and can clamp and conduct current collector films of different thicknesses.

[0030] The connecting cylinder 605 is fixedly installed on the outer wall of the first mounting plate 601, and the connecting plate 606 is fixedly installed on the outer wall of the second mounting plate 604. The connecting plate 606 is slidably connected inside the connecting cylinder 605. A locking bolt 7 is provided on one side of the first limiting plate 602. One end of the locking bolt 7 passes through the outer wall of the first limiting plate 602 and is threadedly connected inside the first mounting plate 601 and the second mounting plate 604.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
