A roll-to-roll electroplating equipment

Abstract

This utility model discloses a roll-to-roll electroplating device. During operation, the base film sequentially passes through an unwinding module, a wetting module, a web guiding module, an electroplating module, and a winding module. The unwinding module unwinds the base film and adjusts its tension by controlling the unwinding speed. The wetting module cleans and wets the base film surface. The electroplating module electroplats the base film surface. Finally, the winding module winds the base film and adjusts its tension by controlling the winding speed. Throughout the base film's journey, the orientation of the web guiding roller is adjusted by a web guiding component to prevent the base film from deviating from its intended path. An active drive component drives an active roller to rotate, transmitting power to the base film. A traction drive component then drives a traction roller to move closer to or further away from the active roller. In the winding module, the base film passes between the traction roller and the active roller, effectively isolating tension and ensuring the stability of the base film's tension.

Description

Technical Field

[0001] This utility model relates to the field of lithium battery manufacturing, specifically to a roll-to-roll electroplating device. Background Technology

[0002] The electroplating tank of the continuous electroplating equipment has several pretreatment tanks at the front end and several posttreatment tanks at the rear end. Each treatment tank contains the required chemical agents, and a conveyor belt is installed above the electroplating tank. The conveyor belt continuously transports the base film through the pretreatment tank, the electroplating tank and the posttreatment tank to complete the continuous electroplating operation.

[0003] In existing continuous electroplating equipment, each segment of the base film moves between two roller devices. If the roller devices on both sides are not properly coordinated, the base film may become too tense and break, or too tense and become loose and deformed, which is detrimental to the coating process. If the coating process cannot be carried out under stable tension, it will seriously affect the dimensional stability of the electroplated product, making it prone to deformation and difficult to control manufacturing quality.

The various technical features in this utility model can be combined interactively without contradicting each other.

[0028] Please see Figure 1-3 This utility model provides a roll-to-roll electroplating device, including a plurality of guide rollers 1 and an unwinding module 2, an immersion module 3, a web guiding module 4, an electroplating module 5, and a rewinding module 6 arranged sequentially. The unwinding module 2 is used to unwind a base film 7, the immersion module 3 is used to clean and wet the surface of the base film 7, the electroplating module 5 is used to electroplat the surface of the base film 7, and the rewinding module 6 is used to rewind the base film 7. The unwinding module 2 and the rewinding module 6 can adjust the tension of the base film 7 by controlling the unwinding speed or the rewinding speed. The guide rollers 1 are interspersed at various points along the belt path of the base film 7, and the guide rollers 1 are used to support and conduct the base film 7, thereby controlling the belt path of the base film 7.

[0029] Please see Figure 2 ,3 6. The correction module 4 includes a correction roller 41 and a correction component 42. The correction component 42 is used to adjust the orientation of the correction roller 41. Both the impregnation module 3 and the winding module 6 are equipped with an active traction assembly 31. The active traction assembly 31 includes an active drive component 310, an active roller 311, a traction drive component 312, and a traction roller 313. The active roller 311 and the traction roller 313 are arranged side by side. The active drive component 310 is used to drive the active roller 311 to rotate, and the traction drive component 312 is used to drive the traction roller 313 to move towards or away from the active roller 311. During the entire conveying process of the base film 7, the correction roller 41 is adjusted by the correction component 42. The orientation is adjusted to prevent the base film 7 transported on the correction roller 41 from deviating. The active roller 311 is driven to rotate by the active drive member 310, and the active roller 311 transmits power to the base film 7. The base film 7 passes between the traction roller 313 and the active roller 311. The traction drive member 312 can drive the traction roller 313 to move closer to or away from the active roller 311. In the impregnation module 3, the base film 7 passing between the traction roller 313 and the active roller 311 can play a role in squeezing and cleaning. In the winding module 6, the base film 7 passing between the traction roller 313 and the active roller 311 can play a role in tension isolation.

[0030] Please see Figure 6 To further limit the movement path of the traction roller 313, the active traction assembly 31 also includes a bracket 314 and a guide assembly 315. The guide assembly 315 includes a slide rail 317 and a slider 316 that are slidably connected. The slide rail 317 is mounted on the bracket 314, and the length direction of the slide rail 317 is the same as the arrangement direction of the active roller 311 and the traction roller 313. The traction roller 313 is mounted on the slider 316. When the traction drive 312 drives the traction roller 313 to move, the traction roller 313 drives the slider 316 to move along the slide rail 317. The movement path of the traction roller 313 is fixed, which can prevent the base film 7 from deviating due to the misalignment of the traction roller 313 and the active roller 311.

[0031] In this embodiment, the active drive unit 310 includes an active motor 318, the stator of which is mounted on the bracket 314, and its rotor is connected to the active roller 311. The traction drive unit 312 includes a traction cylinder 319, the cylinder body of which is mounted on the bracket 314, and its piston rod is connected to the traction roller 313. The rotation of the rotor of the active motor 318 drives the active roller 311 to rotate, thereby conveying the base film 7 forward. The extension and retraction of the piston rod of the traction cylinder 319 drives the traction roller 313 to move towards or away from the active roller 311. The traction cylinder 319 has a simple structure and is easy to install and maintain.

[0032] Please see Figure 3-5Both the unwinding module 2 and the rewinding module 6 are equipped with a swing assembly 21. The swing assembly 21 includes a swing motor 211, a swing arm 212, and a swing roller 213. One end of the swing arm 212 is connected to the rotor of the swing motor 211, and the other end is connected to one end of the swing roller 213. The swing arm 212 is perpendicular to the swing roller 213. The swing roller 213 is rotatably mounted on the swing arm 212. The swing roller 213 is used to transport the base film 7. The swing arm 212 is driven to rotate by the rotor of the swing motor 211, so that the swing arm 212 drives the swing roller 213 to swing, thereby dynamically adjusting the tension of the base film 7 and keeping it stable and consistent during the transport process.

[0033] Please see Figure 4 To limit the rotation range of the swing arm 212, limit blocks 214 are provided on both sides of the swing arm 212 with a gap. The two limit blocks 214 are arranged opposite each other. When the swing arm 212 abuts against the limit block 214, the rotation angle of the swing arm 212 reaches the limit, so as to avoid pulling on the base film 7 transmitted on the swing roller 213 due to excessive swing.

[0034] Please see Figure 2 The immersion module 3 includes an immersion tank 32, and the electroplating module 5 includes an electroplating tank 51. Both the immersion tank 32 and the electroplating tank 51 are equipped with several transmission rollers 52. One end of each transmission roller 52 is connected to a transmission motor 54 via an electromagnetic coupling 53. Both the immersion tank 32 and the electroplating tank 51 are filled with electrolyte. The electrolyte in the immersion tank 32 is used to ensure that the base film 7 is fully immersed during electroplating. The transmission rollers 52 are used to support the base film 7 as it moves through the immersion tank 32 and the electroplating tank 51. The electromagnetic coupling 53 can isolate the current from being conducted through the transmission rollers 52 to the transmission motor 54, thus preventing the transmission motor 54 from being affected by the current.

[0035] In this embodiment, the electroplating module 5 includes two electroplating tanks 51. The base film is electroplated in one electroplating tank 51 and then enters the next electroplating tank 51 for secondary electroplating, thereby extending the electroplating time and improving the electroplating effect.

[0036] Both the correction module 4 and the electroplating module 5 are equipped with several conductive rollers 55. One end of the conductive roller 55 is connected to the drive motor 57 through an insulating coupling 56. The insulating coupling 56 can isolate the conductive roller 55 from the drive motor 57, thus preventing the current on the conductive roller 55 from affecting the drive motor 57. The conductive roller 55 allows the base film 7 to be connected to the electrode to form positive and negative voltages with the electrode plate in the electroplating box 51.

[0037] Please see Figure 3 , 7Both the unwinding module 2 and the winding module 6 include a winding / unwinding assembly 61. The winding / unwinding assembly 61 includes a winding / unwinding motor 611, a gear transmission component 612, and an air shaft 613. The gear transmission component 612 is connected between the air shaft 613 and the rotor of the winding / unwinding motor 611. The rotor of the winding / unwinding motor 611 drives the gear transmission component 612, which transmits power to the air shaft 613 and drives the air shaft 613 to rotate, thereby realizing the winding and unwinding of the base film 7.

[0038] In this embodiment, the gear transmission component 612 includes a first gear 614 and a second gear 615 that mesh with each other. The first gear 614 is connected to the rotor of the take-up and unwind motor 611, and the second gear 615 is connected to the air shaft 613. By using gear combinations with different numbers of teeth on the first gear 614 and the second gear 615, speed can be increased or decreased to meet the speed requirements of the equipment. By changing the gear ratio of the first gear 614 and the second gear 615, the output torque can be changed proportionally while the rotational speed changes.

[0039] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
