Description

Technical Field

[0001] The invention relates to the field of alloy electroplating, in particular to an electroplating fixture for preventing reverse plating. Background Art

[0002] Alloy electroplating is a method of depositing two or more metals on the surface of a workpiece through an electroplating process. By adjusting the electroplating process parameters, the proportion of each metal component can be controlled, so that the alloy coating has excellent properties different from those of a single metal coating, including corrosion resistance, hardness, glossiness and conductivity.

[0003] The electroplating fixture is a tool used to support and fix the workpiece. It can keep the workpiece in the proper position and ensure its reliable contact with the power supply, so as to achieve a stable electroplating effect. Among them, the anti-reverse plating fixture is a fixture design specially used to prevent the "reverse plating" phenomenon during the electroplating process. It is suitable for multi-layer electroplating or fine electroplating scenarios. At present, most of the shielding devices are designed at the contact points of the fixture to prevent the current from acting in reverse on the workpiece surface. The shielding device can be made of special materials that are both conductive and shielding, avoiding reverse current during the electroplating process and damaging the electroplating layer.

[0004] After the workpiece to be electroplated is placed on the fixture, the fixture is hung or installed on the electroplating production line. The mobile end on the production line drives the fixture to move to the electroplating station and other subsequent processing stations.

[0005] During the electroplating process, the conductive parts between the fixture and the workpiece are mostly point contacts, but the traditional contact method is mostly hard contact, that is, the conductive parts on the fixture are hard structures, which may result in a small gap between the fixture and the workpiece. The gap may be caused by the end face of the fixture and the end face of the workpiece being not flat after manufacturing, or the outer surface of the workpiece in contact with the fixture is not flat, which will increase the resistance of the contact point between the fixture and the workpiece, affect the efficiency of current flow, and is not conducive to electroplating.

[0006] Therefore, in order to solve the above problems, a plating fixture for preventing reverse plating is provided. Summary of the invention

[0007] The present invention provides an anti-reverse plating electroplating fixture to solve the problem that the traditional contact mode is mostly hard contact, which leads to an increase in the resistance of the contact part between the fixture and the workpiece.

[0008] The present invention solves the above technical problems through the following technical solutions:

[0009] The present invention provides an anti-reverse plating electroplating fixture, comprising a hanger, a bearing rod is fixed at the bottom of the hanger, a plurality of mounting plates distributed at equal intervals are fixed on the bearing rod, a plurality of fixing components distributed in a ring array are arranged on the mounting plate, and the fixing components are connected to each other with a connecting seat on the side wall of the mounting plate through a connecting rod;

[0011] The conductive part comprises a deformable deformation cover, the interior of the deformation cover is filled with a deformable conductive member, and the deformation cover is in contact with the workpiece.

[0012] In the technical solution of the present application, at least one conductive part is provided on the installation shaft, and the conductive part includes an outer sleeve, and the outer sleeve is fixedly connected to the outer wall of the installation shaft, and an inner connecting tube is slidably connected to the end of the outer sleeve, and a connecting tube is fixed to the end of the outer sleeve, and the surface of the connecting tube is covered with a conductive deformation cover, and the deformation cover is a spherical structure;

[0013] The closing plate is fixed in the inner wall of the inner connecting tube or the connecting tube, the space between the closing plate and the deformation cover is a sealed structure, and the space between the closing plate and the deformation cover is filled with a deformable and conductive conductive member.

[0014] Furthermore, the outside of the deformation cover is wrapped with a limiting cover in a truncated cone structure, and the limiting cover is fixed on the outer wall of the connecting pipe.

[0016] The second spring is sleeved on the surface of the inner connecting tube, and two ends of the second spring are respectively fixed on the outer sleeve and the inner connecting tube.

[0017] Specifically, the conductive part is first pressed inward to make the inner connecting tube on the conductive part slide inward, and the second spring is deformed. Then the installation shaft is extended into the internal cavity of the workpiece. After the installation shaft is extended into the internal cavity of the workpiece, the end of the inner connecting tube is pressed against the inner cavity side wall of the workpiece under the action of the second spring to restore the deformation. At this time, the deformation cover is deformed, and the conductive part filled in the deformation cover is also deformed accordingly. The deformed deformation cover is attached to the workpiece, so that the contact between the conductive part and the workpiece is closer, thereby reducing the resistance.

[0018] In the technical solution of the present application, a branch conductive wire is fixed at the center of the closing plate, one end of the branch conductive wire passes through the closing plate and contacts the conductive part, and the other end of the branch conductive wire is connected to the main conductive wire located in the inner cavity of the load-bearing rod, and the main conductive wire is electrically connected to the connecting part or directly to the power supply.

[0019] The conductive deformation cover, the conductive parts and the branch conductive lines constitute a conductive branch line. The conductive parts inside the deformation cover become more compact after being squeezed, which does not affect the conduction and the electroplating process.

[0020] The connector on the hanger is hung on the movable end of the electroplating production line, and the connector on the hanger is overlapped with the power connection end on the production line. The connector is one of the ways to connect the fixture to the electroplating production line.

[0021] Furthermore, the installation shaft is provided with a plurality of limiting parts distributed in an annular array and cooperating with the conductive part, the limiting parts are distributed on the annular surface of the connecting disk, and the connecting disk is fixed on the installation shaft;

[0022] The limiting part includes a limiting rod, which is slidably connected to the side wall of the connecting disk and is arranged along the radial direction of the connecting disk. A sliding block is arranged on the surface of the limiting rod, and the sliding block is slidably connected to the sliding groove on the inner wall of the connecting disk.

[0023] A first telescopic cover covers the connection between the limiting rod and the connecting disk. A first spring is sleeved on the surface of the limiting rod. Two ends of the first spring are respectively fixed on the limiting rod and the outer wall of the connecting disk.

[0024] First, press the limit rod inwards, the first spring on the limit rod is deformed, and then the installation shaft is extended into the inner cavity of the workpiece. After the limit rod is inserted into the workpiece, the limit rod is pressed against the inner wall of the workpiece under the action of the first spring restoring the deformation trend, thereby fixing the workpiece.

[0028] The driving member includes a connecting plate connected to the transmission rope, a transmission rod is fixed on the top of the connecting plate, the top of the transmission rod is connected to a push-down rod, the push-down rod passes through the top side wall of the mounting shaft, and the push-down rod and the top side wall of the mounting shaft are slidably connected.

[0029] If a fixing assembly and a conductive part are provided on the mounting shaft at the same time, the driving part on the conductive part and the driving part on the limiting part are connected to each other through a transmission rod.

[0030] The first telescopic cover and the second telescopic cover in the present application are both made of insulating materials and are both threaded.

[0031] In the technical solution of the present application, a transmission assembly is also included that can drive the fixed assembly to rotate. The transmission assembly includes a transmission part arranged on the hanger and a connecting part arranged in the inner cavity of the bearing rod. The transmission part is connected to the rack fixed on the electroplating production line in a transmission manner.

[0032] The transmission part is transmission-connected with the connecting part, and the connecting part is transmission-connected with the fixing assembly.

[0033] The transmission part comprises a transmission gear, a driving bevel gear is fixed to one side of the transmission gear, the transmission gear and the driving bevel gear are fixed to each other and arranged coaxially, and the transmission gear is arranged on a connecting frame constituting a hanger;

[0034] A transmission bevel gear, the transmission bevel gear and the driving bevel gear are meshed with each other, a rotatable transmission shaft is fixed at the center of the bottom end of the transmission bevel gear, the transmission shaft passes through the bearing plate and extends to the bottom of the inner cavity of the bearing rod, the transmission shaft is arranged on the bearing plate, and the driven bevel gear on the transmission shaft is connected to the connecting part.

The rotation of the transmission gear drives the driving bevel gear to rotate. The driving bevel gear drives the transmission shaft to rotate through the transmission bevel gear. The driven bevel gear on the transmission shaft also rotates synchronously. The rotating driven bevel gear drives the fixed component on the end of the connecting rod to rotate through the connecting part, thereby driving the workpiece to rotate, so that the workpiece rotates during the electroplating process, making the electroplating more uniform.

[0037] The connecting rod and the connecting seat are rotatably connected, the connecting rod rotates on the connecting seat, and the other end of the universal joint is connected to the end of the connecting rod;

[0038] The horizontal axis passes through the side wall of the bearing rod and the side wall of the mounting plate.

[0039] On the basis of being in accordance with the common sense in the art, the above-mentioned preferred conditions can be arbitrarily combined to obtain the preferred embodiments of the present invention.

[0040] The positive and progressive effects of the present invention are:

[0041] Compared with traditional electroplating fixtures, the conductive connection points between the electroplating fixture and the workpiece to be electroplated in the present application are soft contacts. Through the deformable and conductive deformation cover and conductive parts, the fixture and the workpiece to be electroplated can be fully in contact with each other, which can adapt to workpieces of different structures, reduce the resistance between the contact points between the fixture and the workpiece to be electroplated, improve the current passing efficiency, and facilitate electroplating.

[0042] During the operation of the electroplating production line, in order to ensure that the workpiece can be evenly plated during electroplating, a component that realizes the self-rotation of the workpiece through mechanical transmission is added in this application. When the fixture moves along the production line, the transmission gear moves along the rack and rotates. The self-rotation motion of the transmission gear is further transmitted to the driving bevel gear, which is connected to the transmission bevel gear meshing with it, thereby driving the transmission shaft to rotate synchronously. The rotational motion of the transmission shaft causes the driven bevel gear on it to rotate together.

[0043] The driven bevel gear transmits the rotational power to the end of the connecting rod through the connecting parts, and drives the fixed component to rotate. The fixed component is directly connected to the clamped workpiece, and its rotation also drives the workpiece to rotate. During the electroplating process, the workpiece can rotate continuously and evenly along its own axis, thereby ensuring that the plating solution can fully cover every area of ​​the workpiece surface, avoiding uneven plating, local over-thickness or over-thinness caused by immobility.
