Technical Field

[0001] This utility model relates to a roller electroplating hanger. Background Technology

[0002] Electroplating is a process that uses the principle of electrolysis to deposit a thin film on the surface of metals or other materials to prevent metal oxidation, thereby improving their wear resistance, conductivity, reflectivity, and corrosion resistance.

[0003] Barrel plating is a method in electroplating. During barrel plating, the workpieces to be plated are placed in a rotating drum. However, when multiple workpieces are placed in the drum, although they can be separated during the rolling process, some inevitably overlap and come into contact, resulting in defects in the plated product. Therefore, to address the shortcomings of existing technologies, an improved roller plating rack has been developed to limit the overlapping contact of workpieces. Summary of the Invention

[0004] The purpose of this utility model is to provide a roller electroplating hanger to address the shortcomings of existing technologies.

[0005] In order to achieve the above-mentioned objectives of this utility model, the following technical solution is adopted:

[0006] A roller electroplating hanger includes a suspension frame, a vertical support, at least one set of electroplating fixtures mounted on the vertical support, each set of electroplating fixtures including multiple electroplating fixtures, the multiple electroplating fixtures being vertically spaced and rotatably mounted on the vertical support, adjacent electroplating fixtures being convexly connected; and a driving component, each set of electroplating fixtures being convexly connected to one of the driving components, the driving component being mounted on the suspension frame; wherein, the electroplating fixtures are roller-type electroplating fixtures, the roller-type electroplating fixtures being used to clamp and fix multiple workpieces to be electroplated for rolling electroplating.

[0007] Furthermore, the electroplating fixture includes a first support plate, a second support plate, and a third support plate, which are arranged in parallel and spaced apart, and connected by multiple support rods, which are installed in a circumferentially spaced manner; a first rotating shaft, one end of which is connected to the first support plate, and the other end of which is rotatably mounted on the vertical bracket; a rotating wheel, which drives the third rotating shaft, which passes through the vertical bracket and is connected to a shaft connecting seat; a second rotating shaft, which is detachably connected to the shaft connecting seat; a blocking member, which is installed between adjacent support rods and is detachably connected to the first support plate, the second support plate, and the third support plate; and a limiting rod, each limiting rod corresponding to a blocking member at intervals, and the limiting rod is installed close to the center of the first support plate, the second support plate, and the third support plate.

[0008] Furthermore, adjacent support rods are provided with multiple arc-shaped grooves along their length. Two corresponding arc-shaped grooves can clamp a workpiece to be electroplated. The arc-shaped grooves can restrict the movement of the workpiece to be electroplated along the length of the electroplating fixture.

[0009] Furthermore, the blocking component of the roller electroplating hanger of this utility model includes a stop bar, one end of which passes through a third support plate and extends into a first support plate; a limiting block, which is connected to the other end of the stop bar and fits against one side of the third support plate; and a screw, which passes through the third support plate from the other side and is connected to the limiting block.

[0010] Furthermore, the roller electroplating hanger of this utility model also includes a wing nut, wherein the screw passes through a third support plate and a limiting block and is threadedly connected to the wing nut.

[0011] Furthermore, the present invention provides a roller electroplating hanger that also includes a locking component. The shaft connecting seat has a circumferential groove and an inwardly extending recessed groove on its end face. An installation port is opened on one side of the recessed groove.

[0012] Furthermore, the vertical support includes a first support plate and a second support plate, which are parallel and spaced apart, and are vertically installed on the suspension frame. The first support plate and the second support plate are used to support the electroplating fixture.

[0013] Furthermore, multiple through slots are distributed circumferentially at the connection points between the first support plate and the electroplating fixture on the second support plate and the electroplating fixture.

[0014] Furthermore, the roller electroplating hanger of this utility model also includes reinforcing rods, and at least two reinforcing rods are distributed and installed between the first support plate and the second support plate.

[0015] Furthermore, the driving component includes a drive motor, an output shaft, and a drive wheel. The drive motor is provided with an output shaft, and the output shaft is connected to the drive wheel in a transmission manner.

[0016] This invention features a design that allows each workpiece to be electroplated to be individually clamped and restrained on an electroplating fixture, preventing the workpieces from moving or overlapping.

[0027] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions of this utility model will be clearly and completely described below in conjunction with the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments in this application. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application. Example 1:

[0028] like Figures 1 to 6 As shown, this embodiment of a roller electroplating hanger includes a suspension frame, a vertical support, and a driving component. At least one set of electroplating fixtures is mounted on the vertical support. Each set of electroplating fixtures includes multiple electroplating fixtures 7, which are vertically spaced and rotatably mounted on the vertical support. Adjacent electroplating fixtures are connected by a drive mechanism. Each set of electroplating fixtures is connected to a drive mechanism mounted on the suspension frame. The electroplating fixtures are roller-type electroplating fixtures, used to clamp and fix multiple workpieces to be electroplated in a rolling electroplating manner.

[0029] One structure of the suspension frame includes suspension brackets 2 and suspension rods 3. Suspension brackets 2 are installed at both ends of the suspension rods 3. The suspension brackets 2 are installed on the top of the electroplating tank, and the two suspension brackets support the suspension rods 3 to suspend them from the electroplating tank. The suspension rods, in turn, support the vertical supports to suspend the rods from the electroplating tank.

[0030] One possible shape for the overall structure of an electroplating fixture is a hexagonal roller shape.

[0031] One structure of the driving component is given: the driving component includes a drive motor 11, an output shaft 5, and a drive wheel 6. The drive motor 11 has an output shaft 5, which is connected to the drive wheel 6 for transmission. During operation, the drive motor 11 drives the output shaft 5 to rotate, the output shaft 5 drives the drive wheel 6 to rotate, and the drive wheel 6 drives the electroplating fixture assembly to work, thus driving the electroplating fixture assembly to rotate.

[0032] To protect the drive motor 11, a housing 4 is added. The housing 4 is mounted on the suspension rod 3 and is used to mount the drive motor 11. The housing allows for a closed-loop installation of the drive motor, protecting it and preventing splashes of electroplating solution from contacting the drive motor caused by the rotation of the electroplating fixture.

[0033] Understandably, the output shaft 5 passes through the chassis and is connected to the drive motor. A sealing gasket can be used at the connection between the output shaft and the chassis.

[0034] like Figure 4 As shown, multiple workpieces to be electroplated are clamped at intervals on the electroplating fixture, with adjacent workpieces separated from each other. When the electroplating fixture rotates, the workpieces to be electroplated are confined to their mounting positions, preventing them from moving or coming into contact with each other.

[0035] like Figure 6 As shown, this utility model discloses a structure for holding a workpiece to be electroplated in an electroplating fixture. The workpiece 712 to be electroplated includes a workpiece body 7121, a spiral body 7122, and a spiral groove 7123. The workpiece body 7121 has a disc structure. The spiral body 7122 is provided with a spiral groove 7123.

[0036] like Figure 1 , 2 As shown, the electroplating fixture assembly can be installed in 1, 2, or 3 sets. When multiple sets are installed, the electroplating fixture sets are arranged in parallel and spaced apart. Their rotation does not interfere with each other. It is understood that each electroplating fixture set is connected to a driving component. Therefore, correspondingly, the number of driving components installed can be 1, 2, or 3, etc.

[0037] like Figures 4 to 6 As shown, this is one structure of an electroplating fixture. The electroplating fixture 7 includes a first support plate 711, a second support plate 714, a third support plate 715, a first rotating shaft 71, a rotating wheel 73 and a second rotating shaft 72, a blocking member, and a limiting rod 716. The first support plate 711, the second support plate 714, and the third support plate 715 are arranged in parallel at intervals and connected by multiple support rods 713, which are installed in a circumferentially spaced manner. One end of the first rotating shaft 71 is connected to the first support plate 711, and the other end is rotatably mounted on the vertical bracket. The rotating wheel 73 drives the third rotating shaft 74, which passes through the vertical bracket and connects to the shaft connecting seat 75. The second rotating shaft 72 is detachably connected to the shaft connecting seat 75. A blocking member is installed between adjacent support rods 713, and the blocking member is detachably connected to the first support plate 711, the second support plate 714, and the third support plate 715. Each limiting rod 716 is spaced apart from a blocking member and is installed close to the center of the first support plate 711, the second support plate 714, and the third support plate 715. Multiple arc-shaped grooves 7131 are correspondingly opened along the length direction of adjacent support rods.

[0038] The corresponding arc-shaped grooves of adjacent support rods can be used to clamp the workpiece body 7121 to be electroplated.

[0039] It should be noted that the transmission method between adjacent electroplating fixtures is as follows: the rotating wheels 73 on adjacent electroplating fixtures are connected by a transmission. One structure of the rotating wheels can be gears. Adjacent gears are connected by meshing transmission.

[0040] A transmission connection between a drive component and an electroplating fixture assembly: the drive wheel 6 on the drive component is connected to the rotating wheel of an electroplating fixture in the electroplating fixture assembly.

[0041] When the rotating wheel 73 is a gear, the driving wheel is also a gear. The rotating wheel and the driving wheel are connected by meshing transmission.

[0042] The blocking element and limiting rod 716 prevent the workpiece to be electroplated from detaching radially. The two corresponding arc-shaped grooves on the adjacent support rods restrict the movement of the workpiece to be electroplated along the length of the electroplating fixture.

[0043] It should be noted that the workpiece to be electroplated can be moved slightly between the blocking component and the limiting rod, and within the two corresponding arc-shaped grooves. When the electroplating fixture rotates, the workpiece to be electroplated can be moved slightly in the installation position, which can help the electroplating solution cover the entire workpiece and improve the electroplating quality of the workpiece.

[0044] Understandably, the third rotating shaft 74 can be connected to the vertical support via bearings. The vertical support may have a shaft hole for supporting and mounting the first rotating shaft 71. The first rotating shaft 71 is inserted into the shaft hole, which supports its rotation.

[0045] In some alternative embodiments, one structure of the blocking member is provided. The blocking member includes a stop bar 710, a limiting block 78, and a screw 79. One end of the stop bar 710 passes through the third support plate 715, and the second support plate 714 extends into the first support plate 711; the limiting block 78 is connected to the other end of the stop bar 710 and fits against one side of the third support plate 715; the screw 79 passes through the third support plate 715 from the other side and is connected to the limiting block 78.

[0046] Understandably, both the second support plate 714 and the third support plate 715 have through slots for the stop rod to pass through. The first support plate may have a through slot for the stop rod to pass through or a recessed slot for the stop rod to be inserted.

[0047] The screw is connected to the limiting block, which fixes the limiting block on the third support plate, thereby limiting the stop bar to be located on the first support plate 711, the second support plate 714, and the third support plate 715. When the connection between the screw and the limiting block is released, the stop bar can be pulled out from the first support plate 711, the second support plate 714, and the third support plate 715.

[0048] In some alternative embodiments, an alternative connection structure for the screw is provided, in which a wing nut 77 is added. The screw 79 passes through the third support plate 715 and the limiting block 78 and is threadedly connected to the wing nut 77.

[0049] Understandably, the screw is a capped screw.

[0050] The screw 79 passes through the third support plate 715, the limiting block 78 and the wing nut 77 and is threadedly fixed to each other. The wing nut 77 presses and fixes the limiting block 78 to the third support plate 715, thus achieving a fixed connection of the limiting block 78. Therefore, the limiting block restricts the stop bar to be fixed to the first support plate 711, the second support plate 714 and the third support plate 715.

[0051] In some optional embodiments, a connection structure between the second rotating shaft and the shaft connecting seat is provided, with the addition of a locking member 76. The shaft connecting seat 75 has a circumferential groove and an inwardly extending recess on its end face, with an installation opening on one side of the recess; the locking member 76 engages with the groove and has an unlocking opening; wherein, when the installation opening corresponds to the unlocking opening, the second rotating shaft 72 is inserted into and removed from the recess through the unlocking opening and the installation opening.

[0052] The second rotating shaft is connected to the shaft connecting seat in a transmission manner. That is, the locking member 76 is rotated so that the unlocking port of the locking member 76 is aligned with the mounting port on the shaft connecting seat. At this time, the second rotating shaft 72 is inserted into the groove through the unlocking port and the mounting port. Then the locking member is rotated so that the unlocking port of the locking member is offset from the mounting port. The locking member then closes the mounting port, thereby restricting the second rotating shaft to be located in the groove of the shaft connecting seat. Thus, the second rotating shaft is connected to the shaft connecting seat in a transmission manner.

[0053] When the unlocking port and the installation port are misaligned, they can form a 90° angle.

[0054] The second rotating shaft separates from the shaft connecting seat, that is, the unlocking port of the rotating locking part is aligned with the installation port, and the sink is in the open state. The second rotating shaft can move outward from the sink through the installation port and the unlocking port, so as to disengage the second rotating shaft from the shaft connecting seat.

[0055] like Figure 5 As shown, the outer circumference of the locking member 76 is provided with protrusions distributed at circumferential intervals. The top and bottom of the sides of the protrusions are connected by arc transitions.

[0056] How electroplating fixtures work:

[0057] Install the workpiece 712 to be electroplated into the corresponding two arc-shaped slots on adjacent support rods. After installation, install the blocking parts, and repeat this cyclical operation until workpieces to be electroplated are installed between adjacent support rods on the electroplating fixture. Insert the first rotating shaft 71 into the vertical bracket, and then insert the unlocking port and installation port of the second rotating shaft into the recess of the shaft connecting seat. Rotate the locking part, and the locking part restricts the second rotating shaft to be located in the recess. Repeat this cyclical operation to install all electroplating fixtures.

[0058] Start the drive motor 11, which drives the output shaft 5 to rotate. The output shaft 5 drives the drive wheel 6 to rotate, and the drive wheel 6 drives a rotating wheel 73 connected to it to rotate. All the rotating wheels on the electroplating fixture group to which this rotating wheel belongs follow the rotation, and the electroplating fixture rotates. At this time, the condition of the workpiece to be electroplated on each electroplating fixture group can be checked. After the inspection is qualified, the electroplating work can be carried out.

[0059] During electroplating, the electroplating fixture keeps the electroplated workpieces on it rolling. While rolling, each electroplated workpiece is confined to its own mounting position, but the workpiece can move slightly within the mounting position. This can prevent roller marks from appearing during electroplating, improve the consistency of appearance, and thus improve the quality of electroplating.

[0060] In some alternative embodiments, a structure for the vertical support is provided. The vertical support includes a first support plate 1 and a second support plate 9, which are parallel and spaced apart, and are vertically installed on the suspension frame. The first support plate 1 and the second support plate 9 are used to support the electroplating fixture 7.

[0061] Multiple through slots 10 are distributed circumferentially at the connection points between the first support plate 1 and the second support plate 9 and the electroplating fixture 7.

[0062] like Figure 2 , 3 As shown, multiple through slots 10 can be distributed in a plum blossom shape. Multiple through slots facilitate the passage of electroplating solution through the support plate and the flow of electroplating solution at the connection between the electroplating fixture and the support plate. This facilitates the rotation of the electroplating fixture, which drives the flow of electroplating solution on both sides of the fixture, and further facilitates the flow of electroplating solution around the fixture, ensuring that the electroplated workpiece on the fixture is in full contact with the electroplating solution.

[0063] In some optional embodiments, to further increase the connection stability between the first support plate and the second support plate, reinforcing rods 8 are added. At least two reinforcing rods 8 are distributed and installed between the first support plate 1 and the second support plate 9.

[0064] The number of reinforcing bars installed can be 2, 3, or 4, etc.

[0065] One method of installing reinforcing rods: Two reinforcing rods are installed in parallel with a gap between the bottom of the first support plate and the second support plate, and one or two reinforcing rods can be installed in the middle.

[0066] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
