Description

Technical Field

[0001] This invention relates to the field of electroplating equipment technology, and in particular to a swing device for an electroplating rack. Background Technology

[0002] Electroplating is a surface treatment method in which a pre-plated metal is placed in an electroplating tank, and the substrate metal to be plated is suspended in the electroplating solution by a bracket. Through electrolysis, the cations of the pre-plated metal in the electroplating solution are deposited on the surface of the substrate metal to form a plating layer. For example, in the current electroplating of PCB boards, most PCB boards are clamped together by a bracket and placed into the electroplating tank. However, air bubbles and gases easily adhere to the surface of the PCB board and enter the electroplating tank. It is difficult to remove these bubbles and gases. Since the areas with air bubbles are non-conductive during the electroplating process, metal cannot be deposited on these areas of the PCB board surface, resulting in uneven electroplating on the surface of the workpiece. Summary of the Invention

[0003] The main objective of this invention is to provide a swing device for an electroplating rack, which aims to solve the problem of uneven electroplating caused by air bubbles adhering to the surface of existing electroplating parts.

[0004] To achieve the above objectives, the present invention provides a swing device for an electroplating hanger, comprising:

[0005] A frame, on which a first track and a second track are arranged opposite to each other;

[0006] The hanging rack includes a first body and a second body slidably connected to the first body, the second body being provided with a clamping assembly for holding the workpiece to be electroplated;

[0007] A drive component is connected to the first body, and the drive component is used to drive the first body to move along the first track;

[0008] And a slider, which is connected to the second body and slidably connected to the second track;

[0009] The second track has a wave-shaped groove extending in the same direction as the first track. The slider moves along the wave-shaped groove under the drive of the second body, so that while the second body moves along the extension direction of the first track, it slides back and forth relative to the first body, thereby driving the electroplating part held by the clamp assembly to swing back and forth.

[0010] In one embodiment, the first track extends laterally, the path of the wave-shaped chute fluctuates longitudinally, and the second body can move longitudinally relative to the first body.

[0011] In one embodiment, the first track extends laterally, the path of the wave-shaped chute fluctuates vertically, and the second body can move vertically relative to the first body.

[0012] In one embodiment, the wave-shaped groove extends through both ends of the second track along its length.

[0013] In one embodiment, the drive assembly includes a sprocket and a chain. The sprocket is connected to the first body. When the sprocket is engaged with the chain, the chain drives the sprocket to move in one direction, so that the first body moves along the first track.

[0014] In one embodiment, the swing device for the electroplating rack further includes a guide assembly connected to the first body. The guide assembly includes fixed seats on both sides of the first body along its length and a first guide wheel rotatably connected to the fixed seats. The first guide wheel abuts against the top surface of the first track.

[0015] In one embodiment, the guiding assembly further includes a second guide wheel rotatably connected to the fixed base, the second guide wheel being located on both sides of the first track extension direction, and the second guide wheel abutting against the side of the first track.

[0016] In one embodiment, one of the first body and the second body is hollow and has a groove, and the other body is inserted into the groove to achieve a sliding connection.

[0017] In one embodiment, the first body is provided with a first conductive plate for connecting to an external power supply device, and the clamp assembly is provided with a second conductive plate. The first conductive plate and the second conductive plate are electrically connected to guide the current provided by the power supply device to the workpiece to be electroplated.

[0018] In one embodiment, the first conductive plate is connected to a conductive connecting flat plate, the conductive connecting flat plate extending to one end of the first body near the second body, and a flexible conductive element connecting the conductive connecting flat plate and the second conductive plate.

[0019] The technical solution of this invention involves setting a first rail on a frame, allowing the hanger to move along the first rail under the drive of a drive component when placed on the frame. The hanger includes a first main body and a second main body slidably connected to the first main body. The frame also has a second rail opposite to the first rail, and a sliding member is connected to the second main body and slidably connected to the second rail. Because the second rail forms a wave-shaped groove extending in the same direction as the first rail, while the drive component moves the hanger, the sliding member moves along the wave-shaped groove under the drive of the hanger. That is, while moving along the extension direction of the first rail, the sliding member also oscillates back and forth along the undulation direction of the wave-shaped groove. The sliding member is connected to the second main body, and the second main body moves synchronously with the sliding member, so that while moving along the extension direction of the first rail, the second main body also slides back and forth relative to the first main body under the drive of the sliding member. The second main body is equipped with an angled assembly for clamping the workpiece to be electroplated. When the workpiece is clamped by the clamping assembly, it moves along the extension direction of the first track under the drive of the second main body and slides back and forth relative to the first main body. That is, through the cooperation structure between the second track, the sliding member, and the second main body, the reciprocating swing of the workpiece can be achieved without adding any other driving source, based on the linear movement of the workpiece. The overall structure of the swing device for the electroplating rack is simple and effective, and saves energy. Attached Figure Description

[0030] The present invention proposes a swing device 10 for an electroplating rack. The swing device 10 can drive the workpiece to be electroplated to move linearly, and can also realize the reciprocating swing of the workpiece to be electroplated. By swinging, the workpiece to be electroplated can effectively get rid of the air bubbles attached to the surface, thereby achieving uniform electroplating on the surface of the workpiece to be electroplated.

[0031] Please see Figures 1 to 3In this embodiment, the swing device 10 for the electroplating rack includes a frame 100, a hanger 200, a drive assembly 400, and a sliding member 300. The frame 100 is provided with a first rail 110 and a second rail 120 arranged opposite to each other. The hanger 200 includes a first body 210 and a second body 220 slidably connected to the first body 210. The second body 220 is provided with a clamping assembly 230 for holding the workpiece to be electroplated. The drive assembly 400 is connected to the first body 210 and is used to drive the first body 210 along... The first track 110 moves; the slider 300 is connected to the second body 220 and slidably connected to the second track 120; wherein, the second track 120 forms a wave-shaped groove 121 extending in the same direction as the first track 110, and the slider 300 moves along the wave-shaped groove 121 under the drive of the second body 220, so that while the second body 220 moves along the extension direction of the first track 110, it slides back and forth relative to the first body 210, thereby driving the electroplating part held by the clamp assembly 230 to swing back and forth.

[0032] By setting a first rail 110 on the frame 100, when the hanger 200 is placed on the frame 100, it can move along the first rail 110 under the drive of the drive component. The hanger 200 includes a first body 210 and a second body 220 slidably connected to the first body 210. The frame 100 is also provided with a second rail 120 opposite to the first rail 110. A slider 300 is connected to the second body 220 and slidably connected to the second rail 120. Since the second rail 120 forms a wave-shaped groove 121 extending in the same direction as the first rail 110, when the drive component drives the hanger 200 to move, the slider 300 moves along the wave-shaped groove 121 under the drive of the hanger 200. That is, while the slider 300 moves along the extension direction of the first rail 110, it also swings back and forth along the undulation direction of the wave-shaped groove 121. The sliding member 300 is connected to the second body 220. The second body 220 moves synchronously with the sliding member 300, meaning that while the second body 220 moves along the extension direction of the first track 110, it also reciprocates relative to the first body 210 under the influence of the sliding member 300. The second body 220 is provided with an angled assembly for clamping the workpiece to be electroplated. When the workpiece to be electroplated is clamped by the clamping assembly 230, it moves along the extension direction of the first track 110 under the influence of the second body 220 and reciprocates relative to the first body 210. That is, through the cooperative structure between the second track 120, the sliding member 300, and the second body 220, the reciprocating swing of the workpiece can be achieved without adding any other driving source, based on the linear movement of the workpiece to be electroplated. The overall structure of the swing device 10 for the electroplating rack is simple and effective, and saves energy.

[0033] Please see Figure 1 and Figure 3In one embodiment, the first track 110 extends laterally, and the path of the corrugated groove 121 fluctuates longitudinally. The second body 220 can move longitudinally relative to the first body 210. The corrugated groove 121 on the second track 120 extends in the same direction as the first track 110, that is, the corrugated groove 121 extends laterally, and the path of the corrugated groove 121 fluctuates longitudinally, so that when the slider 300 moves along the corrugated groove 121, it oscillates back and forth in the direction approaching and moving away from the first track 110. The second body 220 can move longitudinally relative to the first body 210. Driven by the slider 300, the second body 220 oscillates back and forth relative to the first body 210 in the longitudinal direction. Specifically, the wave groove 121 can be disposed on the top surface of the second track 120, the slider 300 is disposed in the wave groove 121 and located on one side of the second body 220, and the slider 300 is connected to the second body 220 through the opening of the wave groove 121 at the top surface of the second track 120.

[0034] Unlike the previous embodiment, in another embodiment, the first track 110 extends laterally, and the path of the wave-shaped groove 121 fluctuates vertically. The second body 220 can move vertically relative to the first body 210. The wave-shaped groove 121 on the second track 120 extends in the same direction as the first track 110, that is, the wave-shaped groove 121 extends laterally, and the path of the wave-shaped groove 121 fluctuates vertically, so that the slider 300 oscillates vertically as it moves along the wave-shaped groove 121. The second body 220 can move vertically relative to the first body 210. Driven by the slider 300, the second body 220 oscillates vertically relative to the first body 210, that is, it oscillates up and down. Specifically, the wave groove 121 can be set on the side of the second track 120 facing away from the first track 110. The slider 300 is set in the wave groove 121 and located on one side of the second body 220. The slider 300 is connected to the second body 220 through the opening of the wave groove 121 on the side of the second track 120.

[0035] It is understood that the first track 110 is not limited to extending laterally, but can also extend in other directions, only requiring adaptive adjustments to the undulation direction of the wave groove 121's path. For example, when the first track 110 extends longitudinally, the path of the wave groove 121 can undulate left and right laterally or up and down vertically; when the first track 110 extends vertically, the path of the wave groove 121 can undulate left and right laterally or back and forth vertically.

[0036] Furthermore, in one embodiment, the corrugated groove 121 extends through both ends of the second track 120 along its length. The corrugated groove 121 extends through both ends of the second track 120 along its length, allowing the sliding member 300 to directly enter the corrugated groove 121 through an opening at one end, and then slide out through an opening at the other end. This facilitates convenient loading and unloading of the workpiece by the hanger 200 before and after the electroplating process.

[0037] Specifically, the slider 300 can be configured as a pulley. The slider 300 abuts against the two end faces in the width direction of the wave groove 121. When the slider 300 moves along the wave groove 121, it rolls relative to the two end faces in the width direction of the wave groove 121. While the slider 300 rolls relative to the two end faces in the width direction of the wave groove 121, the two end faces in the width direction of the wave groove 121 also limit the slider 300, preventing it from moving within the width direction of the wave groove 121 and restricting its movement to follow the undulating path of the wave groove 121. Simultaneously, since the second body 220 and the slider 300 move synchronously, the upper limit of the slider 300 in the width direction of the wave groove 121 also limits the range of movement of the second body 220 in the width direction of the wave groove 121.

[0038] Please see Figures 1 to 3Specifically, in one embodiment, the drive assembly 400 includes a sprocket 410 and a chain 420. The sprocket 410 is connected to the first body 210. When the sprocket 410 is engaged with the chain 420, the chain 420 drives the sprocket 410 to move unidirectionally, causing the first body 210 to move along the first track 110. The conveying direction of the chain 420 is the same as the extension direction of the first track 110. When the sprocket 410 is engaged with the chain 420, the sprocket 410 remains stationary relative to the chain 420, and moves together with the chain 420 along the extension direction of the first track 110. The sprocket 410 is connected to the first body 210, causing the first body 210 to move together with the first track 110 under the drive of the sprocket 410.

[0039] Please see Figure 1 and Figure 2 In one embodiment, the swing device 10 for the electroplating rack further includes a guide assembly 500 connected to the first main body 210. The guide assembly 500 includes fixed seats 510 disposed on both sides of the first main body 210 along its length, and a first guide wheel 520 rotatably connected to the fixed seats 510. The first guide wheel 520 abuts against the top surface of the first track 110.

[0040] Furthermore, to prevent the rolling path of the first guide wheel 520 from deviating from the extension direction of the first track 110, a guide groove extending in the same direction as the first track 110 can be provided on the top surface of the first track 110. The first guide wheel 520 rolls along the guide groove, and the inner walls on both sides of the guide groove can limit the first guide wheel 520 to prevent it from leaving the first track 110.

[0041] In another embodiment, the guide assembly 500 further includes second guide wheels 530 rotatably connected to the fixed base 510. The second guide wheels 530 are located on both sides of the first track 110 in the extending direction, and abut against the side of the first track 110. That is, during the movement of the first body 210 along the first track 110, the first guide wheel 520 rolls along the top surface of the first track 110, and the second guide wheels 530 on both sides of the first track 110 roll along the side of the first track 110. By using the second guide wheels 530 on both sides of the first track 110, the first guide wheel 520 is limited on the top surface of the first track 110, preventing the first guide wheel 520 from detaching from the first track 110.

[0042] As described above, the second body 220 is slidably connected to the first body 210. In one embodiment, one of the first body 210 and the second body 220 is hollow and has a groove, with the other inserted into the groove to achieve a sliding connection. For example, when both the first body 210 and the second body 220 extend longitudinally, and the second body 220 can move longitudinally relative to the first body 210, the second body 220 can be directly hollow in the longitudinal direction, and the first body 210 can be directly inserted into the cavity formed by the hollow structure of the second body 220. Specifically, the first body 210 and the second body 220 are made of square tubing, which has a simple structure and is easy to install, reducing production costs.

[0043] It is understandable that during the electroplating process, it is necessary to energize the workpiece to be electroplated. Therefore, in one embodiment, the first main body 210 is provided with a first conductive plate 600 for connecting to an external power supply device, and the clamp assembly 230 is provided with a second conductive plate 700. The first conductive plate 600 and the second conductive plate 700 are electrically connected to guide the current provided by the power supply device to the workpiece to be electroplated.

[0044] Considering that the position of the connection between the second body 220 and the first body 210 will change during the swinging process of the second body 220 relative to the first body 210, for example, when the second body 220 moves longitudinally relative to the first body 210, the distance between the first body 210 and the second body 220 will change, which in turn will cause the distance between the included angle component and the first body 210 to change. If the first conductive plate 600 and the second conductive plate 700 are directly connected by a fixed guide such as a flat iron, the swinging movement of the second body 220 will be restricted.

[0045] Please see Figure 2To address the aforementioned issues, in one embodiment, the first conductive plate 600 is connected to a conductive connecting flat 900. The conductive connecting flat 900 extends from the end of the first main body 210 near the second main body 220. A flexible conductive element 800 connects the conductive connecting flat 900 and the second conductive plate 700. The conductive connecting flat 900 can be a flat iron or other fixed conductor, extending the conductive distance of the first conductive plate 600. The flexible conductive element 800 connects the conductive connecting flat 900 and the second conductive plate 700, achieving conductivity between the first conductive plate 600 and the second conductive plate 700. Because the flexible conductive element 800 is flexible, it can undergo corresponding flexible deformation according to the movement of the second main body 220 during the swinging process of the second main body 220. This does not affect the stable conductivity between the first conductive plate 600 and the second conductive plate 700, nor does it restrict the swinging movement of the second main body 220. Specifically, the flexible conductive element 800 includes, but is not limited to, flexible wires. Preferably, the first conductive plate 600, the second conductive plate 700, the conductive connecting flat plate 900, and the flexible conductive element 800 are arranged close to the bottom surface of the bracket 200 to improve safety during conduction.
