Detailed Implementation

[0038] Various exemplary embodiments of this application will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of this application.

[0039] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the scope of this application and its application or use.

[0040] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0041] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0042] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0043] like Figures 1-8 As shown, according to a first aspect of the embodiments of this application, a conductive roller 100 is provided, including a roller 1, a mounting assembly 2, a conductive ring 3, and a conductive brush assembly 4; the roller 1 is used to transport a base film; the mounting assembly 2 is rotatably connected to the roller 1; the conductive ring 3 is sleeved on the circumference of the roller 1; the conductive brush assembly 4 is disposed on the mounting assembly 2, and the conductive brush assembly 4 abuts against the conductive ring 3.

[0044] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, the conductive roller 100 includes a roller 1, a mounting assembly 2, a conductive ring 3, and a conductive brush assembly 4; wherein, the roller 1 is rotatably connected to the mounting assembly 2, and the roller 1 can rotate relative to the mounting assembly 2 about its own axis, and the base film is on the surface of the roller 1, thereby realizing the transport of the base film by the rotation of the roller 1 itself.

[0045] In related technologies, the conductive components of the conductive roller 100 are usually directly mounted on the roller 1. Since the roller 1 is passively rotated, mounting the conductive components on the roller 1 increases the weight of the roller 1, thereby increasing the rotational inertia of the roller 1, reducing the rotational speed of the conductive roller 100 and affecting the conveying speed of the base film.

[0046] like Figure 2 and Figure 3 As shown, in the embodiment of this application, a conductive ring 3 is circumferentially sleeved on the roller 1. That is, a conductive ring 3 is sleeved on the surface of the roller 1. The conductive ring 3 is close to the end of the roller 1 in the axial direction, so as not to affect the roller 1's conveying of the base film. The conductive brush assembly 4 is disposed on the mounting assembly 2. The conductive brush assembly 4 is externally connected to a power line. The conductive brush assembly 4 abuts against the conductive ring 3. The conductive ring 3 is sleeved on the roller 1, so that the roller 1 can receive current.

[0047] In the embodiment of this application, the conductive roller 100 has a conductive brush assembly 4 mounted on the mounting assembly 2 and electrically connected by abutting against the conductive ring 3. This reduces the weight of the roller 1, thereby achieving a lightweight design of the conductive roller 100. In other words, it reduces the rotational inertia of the roller 1, thereby increasing the rotational speed of the conductive roller 100.

[0048] Preferably, the conductive ring 3 is made of a conductive metal material.

[0049] The conductive roller 1 of this application can be used in electroplating equipment. In one application scenario, during the electroplating process, in order to better transfer the cooling energy of the coating roller to the base film, it is necessary to ensure that the base film and the coating roller are in close contact. The coating roller and the base film are typically connected by electrostatic adsorption, that is, the coating roller and the base film are each charged with two different voltages. The voltage difference causes the base film to adhere to the surface of the coating roller. As the base film passes through the conductive roller 1, the conductive roller 1 provides voltage to the base film, creating a voltage difference between the base film and the coating roller, allowing the base film to adhere tightly to the coating roller. In another application scenario, during the electroplating process, after the base film passes through the coating roller, a coating layer is formed on the surface of the base film. Since the base film contains electrons, the conductive roller 1 can draw out these electrons after the base film passes through it.

[0050] In one alternative embodiment, the conductive brush assembly 4 includes a connector 41 and a conductive element 42. One end of the connector 41 is connected to the mounting assembly 2, and the conductive element 42 is disposed at the other end of the connector 41. The conductive element 42 is capable of abutting against the conductive ring 3.

[0051] like Figure 1 , Figure 2 and Figure 3 As shown, the conductive brush assembly 4 includes a connector 41 and a conductive element 42. One end of the connector 41 is connected to the mounting assembly 2, and the other end of the connector 41 extends along the axial direction of the roller 1 to the position of the conductive ring 3. There is a gap between the connector 41 and the conductive ring 3 to avoid contact between the connector 41 and the conductive ring 3. The conductive element 42 is disposed at the other end of the connector 41. The conductive element 42 is connected to an external power supply line and abuts against the conductive ring 3, thereby realizing the electrical connection between the conductive element 42 and the conductive ring 3.

[0052] In one optional embodiment, the conductive element 42 includes a guide sleeve 421, a carbon brush 422, and a lead plate 423; the guide sleeve 421 has a through hole 4211; the carbon brush 422 includes a first end 4221 and a second end 4222, the first end 4221 being located in the through hole 4211, and the second end 4222 being located outside the through hole 4211 and abutting against the conductive ring 3; the lead plate 423 is connected to the guide sleeve 421, and the lead plate 423 is configured to connect a power line; the guide sleeve 421 is made of a conductive material.

[0053] like Figure 5 and Figure 6 As shown, the conductive component 42 includes a guide sleeve 421, a carbon brush 422, and a lead plate 423.

[0054] To further explain, the other end of the connector 41 is provided with a first mounting hole 411, the axial direction of the first mounting hole 411 is the same as the radial direction of the roller 1; the guide sleeve 421 includes a first part 4212 and a second part 4213, the first part 4212 is disposed in the first mounting hole 411, and the second part 4213 is located outside the first mounting hole 411, with the first part 4212 being closer to the conductive ring 3 relative to the second part 4213.

[0055] To further explain, the guide sleeve 421 has a through hole 4211, which passes through the first part 4212 and the second part 4213. The axial direction of the through hole 4211 is the same as the axial direction of the first mounting hole 411. The first end 4221 of the carbon brush 422 is located inside the through hole 4211, and the second end 4222 of the carbon brush 422 is located outside the through hole 4211. The second end 4222 is closer to the conductive ring 3 than the first end 4221, and the second end 4222 can abut against the conductive ring 3.

[0056] To further explain, such as Figure 8 As shown, the lead plate 423 is connected to the guide sleeve 421. The lead plate 423 has a wiring hole 4231, and the power line is located in the wiring hole 4231. The guide sleeve 421 is made of conductive material, and the carbon brush 422 is located inside the guide sleeve 421, so that the roller 1 can receive current after the carbon brush 422 comes into contact with the conductive ring 3.

[0057] To further explain, the carbon brush 422 has good lubricity, and when it comes into contact with the conductive ring 3, it can reduce the wear of the conductive ring 3; the carbon brush 422 also has good conductivity, thereby improving the conductivity of the conductive roller 1.

[0058] Preferably, the guide sleeve 421 is made of copper, which has good electrical conductivity and low cost.

[0059] In an optional embodiment, the conductive element 42 further includes an elastic element 425 and a limiting rod 424. The limiting rod 424 is embedded inside the through hole 4211, and the elastic element 425 is disposed inside the through hole 4211. The elastic element 425 is located between the limiting rod 424 and the carbon brush 422, and the carbon brush 422 can press the conductive ring 3 through the elastic element 425.

[0060] like Figure 5 and Figure 6 As shown, the conductive component 42 also includes an elastic component 425 and a limiting rod 424; wherein, the limiting rod 424 is embedded inside the through hole 4211, with the end of the limiting rod 424 away from the conductive ring 3 embedded in the through hole 4211; the elastic component 425 is disposed inside the through hole 4211, and the elastic component 425 is located between the limiting rod 424 and the carbon brush 422; when the carbon brush 422 abuts against the conductive ring 3, the elastic component 425 is in a position controlled by the carbon brush 422 and the limiting rod 424. In the compressed state, the elastic force of the elastic element 425 will drive the carbon brush 422 to press against the conductive ring 3. If vibration or slight deviation occurs during the rotation of the roller 1, the carbon brush 422 will remain pressed against the conductive ring 3 under the action of the elastic element 425, thereby improving the stability of the contact between the carbon brush 422 and the conductive ring 3. Furthermore, the carbon brush 422 can compress the elastic element 425 along the axial direction of the through hole 4211 to play a buffering role and prevent the carbon brush 422 from affecting the rotation of the roller 1.

[0061] Among them, the elastic element 425 can be a spring.

[0062] In one specific embodiment, the limiting rod 424 is partially located inside the through hole 4211 and partially located outside the through hole 4211; the lead plate 423 has a second mounting hole 4232, which is fitted onto the part of the limiting rod 424 located outside the through hole 4211, so that the lead plate 423 contacts the guide sleeve 421, and is threadedly connected to the limiting rod 424 by a nut, thereby fixing the lead plate 423 and the guide sleeve 421 together.

[0063] In an optional embodiment, the through hole 4211 includes a first hole segment 4211a and a second hole segment 4211b, the first hole segment 4211a being farther away from the conductive ring 3 relative to the second hole segment 4211b, and the diameter of the first hole segment 4211a being larger than the diameter of the second hole segment 4211b; the carbon brush 422 includes a first segment 4223 and a second segment 4224, the diameter of the first segment 4223 being larger than the diameter of the second segment 4224, and the diameter of the first segment 4223 being larger than the diameter of the second hole segment 4211b; the first segment 4223 is located in the first hole segment 4211a, and the elastic element 425 is located in the first hole segment 4211a.

[0064] like Figure 5 and Figure 6 As shown, the through hole 4211 includes a first hole segment 4211a and a second hole segment 4211b. The diameter of the first hole segment 4211a is larger than the diameter of the second hole segment 4211b, so a first mesa is formed between the first hole segment 4211a and the second hole segment 4211b. The carbon brush 422 includes a first segment 4223 and a second segment 4224. The diameter of the first segment 4223 is larger than the diameter of the second segment 4224, so a second mesa is formed between the first segment 4223 and the second segment 4224. The diameter of the first segment 4223 is larger than the diameter of the second hole segment 4211b.

[0065] To further explain, the first segment 4223 of the carbon brush 422 is located in the first hole segment 4211a, and the second platform faces the first platform. When the carbon brush 422 slides axially relative to the through hole 4211 within the through hole 4211, the first platform abuts against the second platform, which can prevent the carbon brush 422 from disengaging from the through hole 4211.

[0067] like Figure 1 , Figure 4 and Figure 7As shown, the mounting assembly 2 includes a first connecting shaft 21 and a mounting base 25; specifically, the roller 1 includes a first end 11 and a second end 12, which are arranged opposite to each other in the axial direction of the roller 1; the first end 11 of the roller 1 is an end face, and a first connecting hole 111 is provided on the first end 11. The axial direction of the first connecting hole 111 is the same as the axial direction of the roller 1. A first bearing 23 is provided in the first connecting hole 111, and the outer ring of the first bearing 23 abuts against the inner wall of the first connecting hole 111; the first connecting shaft 21 is connected to the inner ring of the first bearing 23, and the first connecting shaft 21 is used to connect with the bracket. Mounting assembly 2 also includes a second connecting shaft 22. The second end 12 of roller 1 is an end face, and a second connecting hole 121 is provided on the second end 12. The axial direction of the second connecting hole 121 is the same as the axial direction of roller 1. A second bearing 24 is provided in the second connecting hole 121, and the outer ring of the second bearing 24 abuts against the inner wall of the second connecting hole 121. The second connecting shaft 22 is connected to the inner ring of the second bearing 24 and is used to connect to the bracket. The roller 1 is rotatably connected to the first connecting shaft 21 and the second connecting shaft 22, thereby enabling roller 1 to rotate around its own axis.

[0068] To further explain, the mounting base 25 is sleeved around the first connecting shaft 21 in the circumferential direction, and the conductive brush assembly 4 is mounted on the mounting base 25. That is, one end of the connector 41 is mounted on the mounting base 25. The mounting base 25 provides an installation position for the conductive brush assembly 4, thereby improving the installation stability of the conductive brush assembly 4.

[0069] In an optional embodiment, the conductive ring 3 includes an abutment portion 31 and a connecting portion 32. The abutment portion 31 is circumferentially disposed on the roller 1, and the connecting portion 32 is connected to the end of the roller 1. The connecting portion 32 has a clearance hole 321, which is used to avoid the first connecting hole 111.

[0070] like Figure 2 and Figure 5 As shown, the conductive ring 3 includes an abutment portion 31 and a connecting portion 32. The conductive ring 3 is integrally formed. The abutment portion 31 is sleeved on the circumference of the roller 1, and the connecting portion 32 abuts against the end of the roller 1. The abutment portion 31 is annular, so that it can be sleeved on the circumference of the roller 1. The connecting portion 32 is plate-shaped and is connected to the edge of one end of the annular ring. The connecting portion 32 and the roller 1 can be connected by bolts or adhesive to improve the connection strength between the conductive ring 3 and the roller 1.

[0071] To further explain, the connecting part 32 is provided with a clearance hole 321, which avoids the first connecting hole 111 so that the first connecting shaft 21 can be connected to the first bearing 23 in the first connecting hole 111.

[0072] In one alternative embodiment, the conductive ring 3 is made of copper; wherein, copper has good conductivity and low cost.

[0073] In one alternative embodiment, the conductive roller 100 includes two conductive brush assemblies 4, which are spaced apart circumferentially along the roller 1.
