Abstract
Description
Technical Field
[0001] This utility model relates to the field of electroplating technology, and in particular to a wheel-type spot plating device. Background Technology
[0002] In the terminal surface electroplating industry, wheel-type spot plating equipment is often used for localized electroplating of terminals. During operation, a ring-shaped plating mold is fitted around the anode, and a plating strip is tightly attached to the outer periphery of the mold, with a waterproof belt covering its outer periphery. The portion of the terminal on the plating strip (i.e., the area to be electroplated, such as a lead) is directly opposite the nozzle on the plating mold. During electroplating, the plating strip is electrically connected to the cathode. As the strip passes through the mold, plating solution is sprayed from the anode onto the localized portion of the terminal. Under the influence of the electric fields of the anode and cathode, metal ions in the plating solution adhere to the surface of the terminal to form a plating layer.
[0003] Traditional wheel-type spot plating devices have the following drawbacks: They require a limiting rod on the outer periphery of the plating mold, which engages with pre-set positioning holes on both sides of the material strip using an insulating material (such as ceramic). To ensure accurate and smooth insertion, the limiting rod's tip needs to be conical. However, during the engagement process, the limiting rod frequently scratches the inner surface of the positioning hole, resulting in burr-like metal wires around the hole and causing product defects. Utility Model Content
[0004] Based on this, the present invention provides a wheel-type spot plating device, which abandons the traditional positioning pin and adopts multiple limiting rods that can be used to clamp the material strip to achieve positioning of the material strip, reduce the risk of scratching the material strip, reduce the burr-like metal wires formed on the material strip, and improve product yield.
[0005] A wheel-type spot plating device, comprising:
[0006] An anode assembly; the anode assembly includes: a disk, and anode plates and nozzles located on the outer periphery of the disk; the number of anode plates is multiple and spaced apart, and at least one nozzle is provided between two adjacent anode plates;
[0007] A spot plating mold for connecting an anode assembly; the spot plating mold includes: a rotating wheel sleeved on the outer periphery of a disc and a positioning assembly located on the outer periphery of the rotating wheel; the rotating wheel is provided with multiple nozzles evenly spaced along the circumference; the positioning assembly includes: a base located on the outer periphery of the rotating wheel and a limiting rod connected to the base; the number of bases is multiple and evenly spaced on the outer periphery of the rotating wheel; each base is provided with at least three spaced limiting rods, and the multiple limiting rods form a clamping groove for clamping the connecting rod between two adjacent terminals of the material strip;
[0008] First guide wheel; multiple first guide wheels used to control the trajectory of the conveyor belt; and
[0009] Second guide wheel; there are multiple second guide wheels, which are used to control the track of the belt.
[0010] In the aforementioned wheel-type spot plating device, during operation, the material strip, guided by the first guide wheel, comes into contact with the spot plating mold mounted on the anode assembly. Furthermore, guided by the second guide wheel, the belt presses against the outer side of the material strip, compressing it against the outer periphery of the spot plating mold. When the material strip is in close contact with the outer periphery of the spot plating mold, the positioning component on the mold contacts the connecting rod between two adjacent terminals on the material strip. The connecting rod is clamped and fixed using a groove formed between multiple limiting rods, thus achieving the positioning function. Because it avoids interfacing with the positioning holes of the material strip and uses multiple limiting rods to clamp and position the connecting rods on the material strip, it effectively reduces the scratching problem caused by interfacing with the positioning holes, thereby reducing the risk of burr-like metal wires and improving product yield. The above design eliminates the need for traditional positioning pins and instead uses multiple limiting rods that can be used to clamp the strip to achieve the positioning of the strip, reducing the risk of scratching the strip, minimizing the formation of burrs on the strip, and improving product yield.
[0011] In one embodiment, the anode assembly further includes: an anode shaft passing through a disc, a spring sleeved on the anode shaft, and a positioning ring sleeved on the anode shaft; one end of the spring abuts against the disc, and the other end of the spring abuts against the positioning ring; the positioning ring is used to adjust the compression of the spring to press the disc tightly onto the anode shaft. When assembling the anode assembly, the disc is first sleeved onto the anode shaft, and then the spring and positioning ring are sequentially sleeved on. By adjusting the depth of the positioning ring, the spring presses the disc tightly. This design facilitates disassembly and assembly, making it convenient for equipment installation, maintenance, and adjustment.
[0012] In one embodiment, the base is detachably embedded in the outer periphery of the rotating wheel. This detachable embedding method facilitates the assembly and disassembly of the positioning component from the rotating wheel.
[0013] In one embodiment, the base is an insulating elastic block, and the bottom ends of each limiting rod are snapped onto the base. The limiting rods are installed on the base using a snap-fit method, making assembly and disassembly convenient.
[0014] In one embodiment, the limiting rod includes: a column connecting to the base and a guide head located at the top of the column; the outer periphery of the column is used to abut against the outer side of the connecting rod; the guide head is used to guide the connecting rod to abut against the outer side of the connecting rod.
[0015] In one embodiment, the guide head has a rounded shape. The rounded shape of the guide head can reduce the resistance between the limiting rod and the connecting rod of the material strip during initial connection.
[0016] In one embodiment, at least one second guide wheel is slidably configured to adjust the tension of the belt. Attached Figure Description

[0040] like Figures 1 to 9 As shown, it is a wheel-type spot plating device 100 according to an embodiment of the present invention.
[0041] like Figure 1 and Figure 2 As shown, the wheel-type spot plating device 100 includes: an anode assembly 10, a spot plating mold 20 connected to the anode assembly 10, a first guide wheel 30, and a second guide wheel 40. See also... Figure 7 and Figure 8 The anode assembly 10 is used to form the anode required for electroplating and to spray the electroplating solution onto the strip 200. The spot plating mold 20 is used to limit the spray range of the electroplating solution, so that the electroplating solution contacts the localized areas on the strip 200 that need to be electroplated. The first guide wheel 30 is used to control the trajectory of the strip 200. The second guide wheel 40 is used to control the trajectory of the belt 300.
[0042] The following text, combined with Figures 1 to 9 The above-mentioned wheel-type spot plating device 100 will be further described.
[0043] like Figure 3 As shown, the anode assembly 10 includes a disk 11, and anode plates 12 and nozzles (not shown) located on the outer periphery of the disk 11. There are multiple anode plates 12 spaced apart, and at least one nozzle is provided between two adjacent anode plates 12. For example, in this embodiment, the anode plates 12 are distributed in a fan-shaped region with a 120° included angle on the upper half of the disk 11. The nozzles are hidden in the gaps between two adjacent anode plates 12.
[0044] For ease of disassembly and assembly, such as Figure 3 and Figure 4 As shown, in this embodiment, the anode assembly 10 may further include: an anode shaft 13 passing through the wheel 11, a spring 14 sleeved on the anode shaft 13, and a positioning ring 15 sleeved on the anode shaft 13. One end of the spring 14 abuts against the wheel 11, and the other end of the spring 14 abuts against the positioning ring 15. The positioning ring 15 is used to adjust the compression of the spring 14 to press the wheel 11 tightly onto the anode shaft 13 (for example, the outer end of the anode shaft 13 is provided with an external thread, and the positioning ring 15 is provided with an internal thread; the feed depth is adjusted by rotating the positioning ring 15). When assembling the anode assembly 10, the wheel 11 is first sleeved onto the anode shaft 13, and then the spring 14 and the positioning ring 15 are sleeved on in sequence. By adjusting the feed depth of the positioning ring 15, the spring 14 presses the wheel 11 tightly. This design is convenient for disassembly and assembly, facilitating the installation, maintenance, and adjustment of the equipment.
[0045] like Figure 5 As shown, the spot plating mold 20 includes: a rotating wheel 21 sleeved on the outer periphery of the wheel 11 and a positioning assembly 22 located on the outer periphery of the rotating wheel 21. The rotating wheel 21 is provided with a plurality of nozzles 211 evenly spaced along the circumference (insulating elastic rubber rings can also be sleeved at the nozzles 211 to improve the sealing at the connection between the nozzles 211 and the material strip 200). Figure 6 As shown, the positioning component 22 includes a base 221 located on the outer periphery of the rotating wheel 21 and a limiting rod 222 connected to the base 221. Multiple bases 221 are evenly spaced on the outer periphery of the rotating wheel 21 (for example, in this embodiment, a positioning component 22 is provided between two adjacent nozzles 211). Here, it can be combined with... Figure 6 and Figure 9 As shown, each base 221 is provided with at least three spaced-apart limiting rods 222, and the multiple limiting rods 222 form a clamping groove for clamping the connecting rod 201 between two adjacent terminals of the material strip 200. For example, in this embodiment, the number of limiting rods 222 is four and they are arranged in a matrix to form a cross-shaped clamping groove.
[0046] Considering the ease of disassembly and assembly, and the fact that the limit rod 222 cannot avoid friction with the connecting rod 201 of the conveyor belt 200 in actual application, the limit rod 222 will also wear out after long-term use.
[0047] Therefore, the following improvements can be made to address the above problems:
[0048] For example, in this embodiment, the base 221 is detachably embedded in the outer periphery of the rotating wheel 21. This detachable embedding method facilitates the assembly and disassembly of the positioning component 22 from the rotating wheel 21. This design allows the entire positioning component 22 to be easily removed from the rotating wheel 21 for replacement.
[0049] For example, the base 221 is an insulated elastic rubber block, and the bottom ends of each limiting rod 222 are snapped onto the base 221. The limiting rods 222 are installed on the base 221 using a snap-fit method, making assembly and disassembly convenient. This design allows for the individual removal and replacement of the limiting rods 222 that need to be replaced without disassembling the base 221.
[0050] Although frictional damage between the limit rod 222 and the connecting rod 201 of the conveyor belt 200 is unavoidable in actual use, the degree of frictional damage can be reduced by improving the limit rod 222. This can not only improve product yield but also extend the service life of the limit rod 222. For example, as... Figure 6 As shown, in this embodiment, the limiting rod 222 includes: a column 2221 connecting to the base 221 and a guide head 2222 located at the top of the column 2221. The outer periphery of the column 2221 is used to abut against the outer side of the connecting rod 201. The guide head 2222 is used to guide the connecting rod 201 to abut against the outer side of the connecting rod 201.
[0051] Furthermore, the guide head 2222 is preferably a round-headed structure. The round-headed guide head 2222 can reduce the resistance during the initial docking of the limiting rod 222 and the connecting rod 201 of the material strip 200.
[0052] In addition, considering durability issues, in this embodiment, the limiting rod 222 can be an integrally formed ceramic column, or the rod body can be a ceramic column and the guide head 2222 can be a rubber head.
[0053] like Figure 1 and Figure 2 As shown, in this embodiment, there are two first guide wheels 30, which are respectively arranged on both sides of the anode assembly 10.
[0054] like Figure 1 and Figure 2 As shown, in this embodiment, there are four second guide wheels 40, which are arranged in pairs on both sides of the anode assembly 10.
[0055] To facilitate material feeding on belt 200, the tension of belt 300 needs to be adjusted frequently. For example... Figure 1 and Figure 2 As shown, in this embodiment, at least one second guide wheel 40 is slidably configured to adjust the tension of the belt 300. For example, as Figure 8 As shown, in this embodiment, the second guide wheel 40 located on the right side of the anode assembly 10 is slidable in the horizontal direction. The tension of the belt 300 can be adjusted by moving it left and right (after adjustment, the position is locked by the insertion of a pin into a pin hole).
[0056] Brief description of working principle:
[0057] like Figure 7 and Figure 8 As shown, during operation, the material strip 200, guided by the first guide wheel 30, fits against the plating mold 20 mounted on the anode assembly 10. Furthermore, the belt 300, guided by the second guide wheel 40, presses against the outer side of the material strip 200, thus pressing the material strip 200 tightly against the outer periphery of the plating mold 20. It should be noted that the belt 300 not only presses the material strip 200 but also prevents the plating solution from overflowing into other areas of the material strip 200 after being sprayed from the nozzle 211 of the rotating wheel 21 onto a predetermined plating area (e.g., the pin of a terminal) from being applied.
[0058] During transport, the material strip 200 is connected to the negative terminal of the power supply via a conductive base to form the cathode required for electroplating. When the material strip 200 passes the spot plating mold 20, the anode assembly 10 is a fixed structure (i.e., the wheel 11 remains stationary during operation), while the spot plating mold 20 is a movable structure. As the material strip 200 moves forward, it drives the spot plating mold 20 to rotate. Since the second guide wheels 40 are all driven wheels, the belt 300 is also driven by the material strip 200. Therefore, when the material strip 200 passes through the upper half of the anode assembly 10, it will pass through the area corresponding to the anode plate 12 and the nozzle. At the same time, under the constraint of the positioning assembly 22, it is ensured that the local area on the material strip 200 that needs to be electroplated (e.g., the pin) is located exactly at the nozzle 211 of the rotating wheel 21. The electroplating solution sprayed from the nozzle passes through the nozzle 211 on the spot plating mold 20 to be sprayed onto the local area on the material strip 200 that needs to be electroplated.
[0059] When the strip 200 is in close contact with the outer periphery of the plating mold 20, the positioning component 22 on the plating mold 20 contacts the connecting rod 201 between two adjacent terminals on the strip 200. The connecting rod 201 is clamped and fixed by a groove formed between multiple limiting rods 222, thus achieving the positioning function. Because the insertion into the positioning hole of the strip 200 is avoided, and multiple limiting rods 222 are used to clamp and position the connecting rod 201 on the strip 200 to achieve the positioning of the strip 200, the scratching problem caused by insertion into the positioning hole can be effectively reduced, thereby reducing the risk of burr-like metal wires and improving product yield.
[0060] The aforementioned wheel-type spot plating device 100 abandons the traditional positioning pin and adopts multiple limiting rods 222 that can be used to clamp the material strip 200 to achieve positioning of the material strip 200, reduce the risk of scratching the material strip 200, reduce the burr-like metal wires formed on the material strip 200, and improve product yield.
[0061] 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.
[0062] 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.
