Abstract
Description
Technical Field
[0001] This utility model relates to the field of electroplating technology, and in particular to a straddle-type wheel-type conductive base. Background Technology
[0002] In the surface electroplating process of products, the products are typically conveyed in the form of a conveyor belt. A conductive base and an electroplating solution tank are positioned along the belt's path. The conductive base is connected to the negative terminal of the power supply, while the electroplating solution tank, containing the electroplating solution, is connected to the positive terminal. As the conveyor belt advances, it contacts the conductive base to form the negative electrode, while the electroplating solution tank acts as the positive electrode. Under the influence of an electric field, metal ions in the electroplating solution accumulate on the conveyor belt and adhere to its surface to form an electroplated layer.
[0003] Traditional conductive bases typically consist of vertically positioned conductive posts. As the conveyor belt advances, two posts are positioned on either side of the belt, with the outer surface of the belt contacting the outer periphery of the posts. The drawback of this traditional design is that the outer surface of the conveyor belt must be a vertical plane, and the contact between the posts and the belt is a sliding friction process, making it easy to scratch the outer surface. When the outer surface of the conveyor belt is beveled and the customer requires no scratches (for example, in an inverted V-shaped terminal with both sides extending outwards in a figure-eight shape, where the customer requires no scratches on either outer surface or the top surface, resulting in high requirements for product appearance integrity), the conductive posts in traditional conductive bases can only achieve very small, localized contact with the outer surface of the conveyor belt (close to line contact rather than surface contact). This not only fails to achieve good electrical contact, leading to poor plating adhesion, but also scratches the outer surface, resulting in a very low yield rate. Utility Model Content
[0004] Based on this, the present invention provides a straddle-type wheel-type conductive seat, which is equipped with a conductive wheel that rolls and contacts the material strip, so that the material strip contacts the conductive wheel in a straddle manner. This not only increases the electrical contact area, but also changes the contact area with the material strip, thereby improving the coating adhesion effect and avoiding scratching the outer surface of the material strip.
[0005] A straddle-type wheeled conductive base, comprising:
[0006] rack; and
[0007] A rolling contact assembly mounted on a frame; the rolling contact assembly includes: a fixed base connected to the frame and a conductive wheel pivotally connected to the fixed base; both the fixed base and the conductive wheel are conductive components; the axis of the conductive wheel is horizontally arranged; the conductive wheel includes: a wheel body, a first limiting sleeve located on one side of the wheel body, and a second limiting sleeve located on the other side of the wheel body; the wheel body, the first limiting sleeve, and the second limiting sleeve are coaxial; the outer diameter of the wheel body is larger than the outer diameter of the first limiting sleeve, and the outer diameters of the first limiting sleeve and the second limiting sleeve are equal; the wheel body is used to contact the bottom surface of the top of the material belt so that the material belt straddles the wheel body.
[0008] In the aforementioned straddling-type conductive seat, the frame is placed on one side of the material belt's forward path during operation, allowing the rolling contact component to contact the material belt and the material belt to straddle the conductive wheel. As the material belt advances, the bottom surface of the top of the material belt contacts the wheel body of the conductive wheel, and the first and second limiting sleeves provide outward extension space for both sides of the material belt. With the material belt's forward movement, the bottom surface of the top of the material belt rolls and rubs against the wheel body. Because the wheel body contacts the bottom surface of the top of the material belt, there is a stable and large contact area, achieving good electrical contact, improving coating adhesion, and preventing scratches on the outer surface of the material belt, thus improving product yield. Through this design, by setting a conductive wheel that rolls and contacts the material belt, allowing the material belt to straddle the conductive wheel, not only is the electrical contact area increased, but the contact area with the material belt is also changed, achieving the purpose of improving coating adhesion and avoiding scratches on the outer surface of the material belt.
[0009] In one embodiment, the frame includes: a base, a guide rod connected at one end to the base, a limiting block connected to the other end of the guide rod, a screw rod parallel to the guide rod and passing through the limiting block, and a lifting platform sleeved on the guide rod and the screw rod; the guide rod is vertically arranged; the screw rod is used to drive the lifting platform to slide up and down along the guide rod; the lifting platform is used to connect to the fixed seat. During operation, rotating the screw can drive the lifting platform to slide up and down along the guide rod, thereby adjusting the height of the fixed seat, thus achieving the purpose of adjusting the height position of the conductive wheel, facilitating the operator to adjust the height position of the conductive wheel to adapt to the movement trajectory of the material belt.
[0010] In one embodiment, the lifting platform is provided with multiple vertically arranged insert rods; the insert rods pass through the fixed base. By inserting the insert rods into the fixed base, the fixed base and the conductive wheel can be used for their own weight. When the fixed base is vertically inserted into the insert rods and falls onto the lifting platform, the fixed base can be stably installed on the lifting platform. The structure is simple and easy to assemble and disassemble.
[0011] In one embodiment, the frame further includes: a conductive plate located on the lifting platform; first lugs for connecting the negative terminal of the power cord are respectively provided on both sides of the conductive plate; the conductive plate is sleeved on the plug rod and located between the lifting platform and the fixed base; the lifting platform is an insulating component. By using the conductive plate as the electrical connection medium between the negative terminal of the power cord and the fixed base, it is not necessary to remove the negative terminal of the power cord when disassembling and assembling the rolling contact assembly, reducing the number of operation steps. At the same time, the lifting platform is an insulating component, improving operational safety.
[0012] In one embodiment, the top of the screw is equipped with an operating head, which is an insulated component. Operators can operate the insulated operating head to drive the screw to rotate, thereby driving the lifting platform to move up and down. This design offers high safety and simple operation.
[0013] In one embodiment, the rolling contact assembly further includes: a pin passing through the conductive wheel; one end of the pin passes sequentially through a first limiting sleeve, the wheel body, and a second limiting sleeve along the axis of the conductive wheel and is detachably connected to the fixed seat; the pin is a conductive component. The conductive wheel can be quickly assembled and disassembled by pulling or rotating the pin, resulting in a simple structure.
[0014] In one embodiment, the mounting base is provided with a second lug for connecting the negative terminal of the power cord. The negative terminal of the power cord can be directly connected to the mounting base, which is simple in structure and easy to operate. Attached Figure Description

[0037] like Figures 1 to 10 As shown, it is a straddle-type wheeled conductive base 100, which is one embodiment of the present invention.
[0038] like Figure 1 and Figure 2 As shown, the straddle-type wheeled conductive base 100 includes: a frame 10 and a rolling contact assembly 20 mounted on the frame 10. (Combined) Figure 8 As shown, the frame 10 is used to support the rolling contact assembly 20, which is used to contact the material belt 300, thereby establishing an electrical connection between the material belt 300 and the negative terminal of the power line 200.
[0039] The following text, combined with Figures 1 to 10 As shown, the straddle-type wheel-type conductive base 100 described above will be further explained.
[0040] In this solution, the frame 10 can be either a non-adjustable or an adjustable structure. Considering that in actual use scenarios, the position of the rolling contact component 20 may need to be adjusted according to the size or forward trajectory of the conveyor belt 300, the following explanation uses a height-adjustable frame 10 as an example.
[0041] like Figure 3 As shown, in this embodiment, the frame 10 includes: a base 11, a guide rod 12 connected at one end to the base 11, a limiting block 13 connected to the other end of the guide rod 12, a screw 14 parallel to the guide rod 12 and passing through the limiting block 13, and a lifting platform 15 sleeved on the guide rod 12 and the screw 14. The guide rod 12 is vertically arranged. The screw 14 drives the lifting platform 15 to slide up and down along the guide rod 12. The lifting platform 15 is used to connect to the rolling contact assembly 20 (specifically, the fixed seat 21 hereinafter referred to as the fixed seat 21). Figure 1 As shown, during operation, rotating the screw 14 can drive the lifting platform 15 to slide up and down along the guide rod 12, thereby adjusting the height position of the rolling contact component 20 to match the movement trajectory of the material belt 300 (specifically, corresponding to the following text, adjusting the height of the fixed seat 21 to achieve the purpose of adjusting the height position of the conductive wheel 22, making it convenient for operators to adjust the height position of the conductive wheel 22 to match the movement trajectory of the material belt 300).
[0042] Furthermore, combined Figure 1 and Figure 4 As shown, the lifting platform 15 can be equipped with multiple vertically arranged insert rods 151. The insert rods 151 pass through the rolling contact assembly 20 (specifically, the fixed seat 21 mentioned below). By inserting the insert rods 151 into the rolling contact assembly 20, the weight of the rolling contact assembly 20 (e.g., the fixed seat 21 and the conductive wheel 22 mentioned below) can be utilized. In addition, the material belt 300 straddles the conductive wheel 22, which means that the material belt 300 also exerts a downward pressure on the rolling contact assembly 20 (specifically, the conductive wheel 22 mentioned below). When the rolling contact assembly 20 is vertically inserted into the insert rods 151 and falls onto the lifting platform 15, the rolling contact assembly 20 can be stably installed on the lifting platform 15, which is simple in structure and easy to assemble and disassemble.
[0043] For ease of operation, such as Figure 3 As shown, in this embodiment, the top end of the screw 14 is provided with an operating head 141, and the operating head 141 is an insulated component. Operators can operate the insulated operating head 141 to drive the screw 14 to rotate, thereby driving the lifting platform 15 to move up and down. This method offers high safety and simple operation.
[0044] like Figure 6 As shown, in this embodiment, the rolling contact assembly 20 includes a fixed base 21 connecting the frame 10 and a conductive wheel 22 pivotally connected to the fixed base 21. Both the fixed base 21 and the conductive wheel 22 are conductive components, such as copper metal components. The axis of the conductive wheel 22 is horizontally oriented. During operation, the fixed base 21 is used to connect (indirectly or directly) to the frame 10 and the negative terminal of the power cord 200. The conductive wheel 22, pivotally connected to the fixed base 21, contacts the bottom surface of the top of the conveyor belt 300 in a rolling manner.
[0045] Combination Figure 7 As shown, in this embodiment, the conductive wheel 22 includes: a wheel body 221, a first limiting sleeve 222 located on one side of the wheel body 221, and a second limiting sleeve 223 located on the other side of the wheel body 221. The wheel body 221, the first limiting sleeve 222, and the second limiting sleeve 223 are coaxial. The outer diameter of the wheel body 221 is larger than the outer diameter of the first limiting sleeve 222, and the outer diameters of the first limiting sleeve 222 and the second limiting sleeve 223 are equal. The wheel body 221 is used to contact the bottom surface of the top of the material strip 300 so that the material strip 300 straddles the wheel body 221. Figure 10In this design, considering that the two sides of the material belt 300 extend outward at an angle, the material belt 300 needs to provide space for movement on both sides during its forward movement. Therefore, the first limiting sleeve 222 and the second limiting sleeve 223, which protrude outward relative to the wheel body 221, can occupy the space on the left and right sides of the material belt 300, thus preventing the two sides of the material belt 300 from colliding with the fixed seat 21 or other objects located outside the conductive wheel 22 during the movement.
[0046] Considering that the conductive wheel 22 will wear out after long-term use and will need to be repaired or replaced, in order to facilitate the disassembly and assembly of the conductive wheel 22, such as Figure 6 As shown, in this embodiment, the rolling contact assembly 20 may further include a pin 23 passing through the conductive wheel 22. One end of the pin 23 passes sequentially along the axis of the conductive wheel 22 through the first limiting sleeve 222, the wheel body 221, and the second limiting sleeve 223, and is detachably connected to the fixed seat 21 (e.g., by a threaded connection, or a limiting connection consisting of a spring and a steel ball). The pin 23 is a conductive component. By pulling or rotating the pin 23, the conductive wheel 22 can be quickly assembled and disassembled, resulting in a simple structure.
[0047] In order to achieve electrical connection between the negative terminal of the power cord 200 and the material strip 300, in this solution, the negative terminal of the power cord 200 can be directly connected to the fixed base 21 or indirectly connected to the fixed base 21.
[0048] For example, combining Figure 1 and Figure 5 As shown, in this embodiment, the frame 10 may further include a conductive plate 16 located on the lifting platform 15. The conductive plate 16 has first lugs 161 on both sides for connecting the negative terminal of the power cord 200. The conductive plate 16 is sleeved on the insertion rod 151 and located between the lifting platform 15 and the fixed base 21 (the fixed base 21 presses the conductive plate 16 firmly onto the lifting platform 15). The lifting platform 15 is an insulating component. By using the conductive plate 16 as the electrical connection medium between the negative terminal of the power cord 200 and the fixed base 21, it is not necessary to disassemble the negative terminal of the power cord 200 when disassembling and assembling the rolling contact assembly 20, reducing operational steps. Simultaneously, the lifting platform 15 is an insulating component, improving operational safety.
[0049] For example, in other embodiments, the mounting base 21 may be provided with a second lug for connecting the negative terminal of the power cord 200. The negative terminal of the power cord 200 can be directly connected to the mounting base 21, which is simple in structure and easy to operate.
[0050] Brief description of working principle:
[0051] like Figure 8As shown, during operation, the frame 10 is placed on one side of the forward path of the conveyor belt 300, so that the rolling contact assembly 20 contacts the conveyor belt 300, and the conveyor belt 300 straddles the conductive wheel 22. Figure 8 Only a small section of the 300mm strip was shown in the image.
[0052] like Figure 9 and Figure 10 As shown, when the material belt 300 moves forward, the bottom surface of the top of the material belt 300 contacts the wheel body 221 of the conductive wheel 22, and the first limiting sleeve 222 and the second limiting sleeve 223 provide outward extension space for both sides of the material belt 300. As the material belt 300 moves forward, the bottom surface of the top of the material belt 300 rolls and rubs against the wheel body 221.
[0053] Because the wheel 221 contacts the bottom surface of the top of the material strip 300, it has a stable and large contact area, which can achieve good electrical contact, improve the coating adhesion, and will not scratch the outer surface of the material strip 300, thus improving product yield. In addition, the wheel 221 and the bottom surface of the top of the material strip 300 are subject to rolling friction, so the damage to the bottom surface of the top of the material strip 300 is also minimal.
[0054] The aforementioned straddling type wheel-type conductive seat 100 is provided with a conductive wheel 22 that rolls in contact with the material strip 300, so that the material strip 300 contacts the conductive wheel 22 in a straddling manner. This not only increases the electrical contact area, but also changes the contact area with the material strip 300, thereby improving the coating adhesion effect and avoiding scratching the outer surface of the material strip 300.
[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0056] The above embodiments only illustrate preferred implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
