Description

Technical Field

[0001] This invention relates to the field of electroplating equipment technology, and more specifically to an electroplating fixture and an electroplating system. Background Technology

[0002] Electroplating fixtures are specialized auxiliary tools used in electroplating processes. They are primarily used to hold the workpiece to be electroplated, ensuring stability, good conductivity, and sufficient contact during the electroplating process. They are typically made of corrosion-resistant materials (such as titanium, stainless steel, or special plastics) and are designed to balance conductivity and chemical resistance, allowing them to withstand the corrosive environments of acidic or alkaline electroplating solutions. Existing electroplating fixtures use spring-spring clips or stainless steel elastic arm clamps for holding the workpiece, thus completing the electroplating operation.

[0003] The clamping force of existing electroplating fixtures varies with spring fatigue. During long-term use, existing electroplating fixtures cannot maintain a stable clamping force, resulting in insufficient clamping force on the workpiece to be electroplated, leading to insecure clamping, or excessive clamping force, which damages the surface of the workpiece and thus affects the electroplating quality. Summary of the Invention

[0004] This invention provides an electroplating fixture and an electroplating system to solve the problem that existing electroplating fixtures cannot maintain a stable clamping force, resulting in unstable clamping force.

[0005] In a first aspect, the present invention provides an electroplating fixture, comprising: First clamping plate, fixed in place; The second clamping plate is rotatably connected to the first clamping plate via the first rotating shaft; A linkage assembly includes a first link, a second link, and a third link. The first link has a first position and a second position. The first link reciprocates axially to switch between the first position and the second position. One end of the first link is hinged to one end of the second link via a second pivot. The other end of the second link is hinged to one end of the third link via a third pivot. The other end of the third link is connected to a second clamping plate. The axes of the first pivot, the second pivot, and the third pivot are parallel. The counterweight drives the first connecting rod to move from the first position to the second position by its own weight. The clamping unit includes two sets of clamping parts, which are respectively fixedly disposed on the first clamping plate and the second clamping plate; When the first connecting rod is in the first position, the second clamping plate forms an angle with the first clamping plate, and the two sets of clamping parts are in the open state; when the first connecting rod is in the second position, the second clamping plate rotates around the first rotating shaft, the surface of the second clamping plate is parallel to the surface of the first clamping plate, and the two sets of clamping parts are closed to clamp the plate to be electroplated.

[0006] Beneficial effects: An external force moves the first connecting rod to the first position, creating an angle between the second and first clamping plates, opening the two clamping parts to accommodate the electroplated workpiece. Then, the weight of the counterweight drives the first connecting rod to fall from the first position to the second position. The angle between the first and second connecting rods changes via the second pivot, causing the second connecting rod to move. Simultaneously, the angle between the second and third connecting rods changes via the third pivot, causing the third connecting rod to move. This movement of the third connecting rod causes the second clamping plate to rotate around the first pivot. The rotation causes the second clamping plate to change from an angle to parallel with the first clamping plate, which in turn causes the two sets of clamping parts to change from an open state to a closed state to clamp the plate to be electroplated. By using the force of the counterweight itself, the clamping force at the clamping point can be precisely controlled, ensuring that the clamping point does not bear the weight of the plate to be electroplated. This provides a stable and uniform clamping force to the plate to be electroplated, ensuring that the clamping force is not too large and will not damage the surface of the plate to be electroplated, thereby ensuring the electroplating quality of the plate to be electroplated.

[0007] In one optional embodiment, the third link includes a first rod and a second rod that are perpendicular to each other. The end of the first rod is hinged to the second link, the end of the second rod is fixedly connected to the second clamping plate, and the connecting end of the first rod and the second rod is hinged to the first rotating shaft.

[0008] Beneficial effects: By configuring the third link into a first and a second link that are perpendicular to each other, and hinged the junction of the first and second links to the first pivot, the third link becomes the medium for driving the second clamping plate to rotate. When the second link drives the first link to rotate around the first pivot, the second link will also rotate around the first pivot and drive the second clamping plate to rotate. This allows the second clamping plate to open and close with the first clamping plate, better ensuring the stability of the second clamping plate during the opening and closing process, and further ensuring that the clamping part can provide a stable clamping force for the plate to be electroplated.

[0009] In one optional embodiment, the electroplating fixture further includes a conductive plate and a fixing frame, the first connecting rod is movably disposed on the conductive plate, the clamping part is electrically connected to the conductive plate, the fixing frame and the conductive plate together form an electroplating frame, and the second clamping plate and the first clamping plate are respectively located on both sides of the electroplating frame.

[0010] Beneficial effects: By providing a stable current to the clamping part through the conductive plate, the clamping part can provide a combined function of clamping, positioning, and conducting electricity for the workpiece to be electroplated. Furthermore, the fixing frame and the conductive plate together form an electroplating frame, which on the one hand enhances the overall rigidity of the workpiece to be electroplated, and on the other hand provides a reference surface for clamping the workpiece, thereby ensuring that the workpiece maintains clamping stability under the impact of the electroplating liquid flow after clamping.

[0011] In one alternative embodiment, a guide block is fixedly disposed on the conductive plate, and at least a portion of the first connecting rod along the axial direction is slidably disposed inside the guide block.

[0012] Beneficial effects: By setting the guide block, the movement of the first link between the first position and the second position is guided, ensuring that the first link moves between the first position and the second position along a fixed trajectory, and further ensuring the stability of the clamping.

[0013] In one optional embodiment, each set of clamping parts is provided with multiple jaws, and the jaws on the two sets of clamping parts are arranged in a one-to-one correspondence. Each jaw is provided with a clamping post, and the ends of the two clamping posts of a pair of jaws are arranged opposite to each other. The end of the clamping post has a hemispherical chuck. When the two sets of clamping parts are closed, the chuck and the surface of the plate to be electroplated form a point contact.

[0014] Beneficial effects: By using the hemispherical chucks at the ends of the clamping columns, combined with the opposing clamping structure of the two sets of clamping parts, a continuous curved surface replaces traditional line contact or sharp point contact, eliminating the potential for localized indentations, micro-cracks, and edge chipping on the workpiece to be electroplated, thus avoiding mechanical damage. Furthermore, the hemispherical opposing clamping chucks, combined with the weight of the counterweight, allow for precise control of the chuck force, ensuring that the chucks remain firmly in contact with the surface of the workpiece while maintaining electrical conductivity, achieving a zero-fragmentation clamping effect.

[0015] In one optional embodiment, a first cover plate is fixedly provided on the first clamping plate, and the first cover plate has a plurality of first electroplating ports, and the plurality of first electroplating ports are correspondingly provided with a set of clamping parts provided on the first clamping plate.

[0016] Beneficial effects: By setting the first shield, the electric field distribution on the surface of the workpiece to be electroplated can be constrained. The first electroplating port opened on the first shield can constrain the electric field distribution on the surface of the workpiece to be electroplated while ensuring that the electroplating solution can fully contact the surface of the workpiece to be electroplated, thereby achieving efficient electroplating.

[0017] In one optional embodiment, a plurality of second cover plates are fixedly disposed on the second clamping plate, and the plurality of second cover plates are correspondingly disposed with a set of clamping portions disposed on the second clamping plate, and a second electroplating port is provided on the second cover plate.

[0018] Beneficial effects: By setting a second shield, in conjunction with the first shield, the electric field distribution on the surface of the workpiece to be electroplated is constrained. There are multiple second shields, and the opening angle of each second shield can be controlled to adjust the electric field distribution on the surface of the workpiece to be electroplated held in each pair of opposite clamping parts in real time. This weakens the peak value of the current density and fills in the valley value of the current density, thereby ensuring that the electric field distribution on the surface of the workpiece to be electroplated in each pair of opposite clamping parts can be kept at a uniform level. This eliminates the defect of thick edge plating and thin center plating caused by tip discharge of the clamping point contact, ensuring the uniformity of the plating on the surface of the workpiece to be electroplated and improving the efficiency and quality of the electroplating process.

[0019] In one alternative embodiment, one side of the second baffle is formed with an inclined surface, and a baffle is provided on the fixing frame. One side of the baffle is also formed with an inclined surface. When the surface of the second clamping plate is parallel to the surface of the first clamping plate, the inclined surface of the baffle and the inclined surface of the second baffle abut against each other.

[0020] Beneficial effects: The present invention uses the inclined surface of the second shield to abut against the inclined surface of the baffle. On the one hand, it restricts the second shield from moving further toward the plate after abutting against the baffle, ensuring that the position of the chuck against the surface of the plate to be electroplated is fixed. On the other hand, it prevents the movement of the second shield from causing the chuck to apply excessive clamping force to the plate, which could damage the plate and improve the accuracy of the clamping force.

[0021] In one optional embodiment, both the first and second shields are provided with a plurality of flow equalization holes, the plurality of flow equalization holes on the first shield surrounding the first electroplating port, and the plurality of flow equalization holes on the second shield surrounding the second electroplating port.

[0022] Beneficial effects: By setting multiple flow equalization holes around the first and second electroplating ports, it can be ensured that the electroplating solution can flow evenly onto the surface of the workpiece to be electroplated, ensuring that a uniform coating can be produced on the surface of the workpiece, and further improving the efficiency and quality of the electroplating process.

[0023] In one optional embodiment, a first stop and a second stop are fixedly disposed on the fixing frame, the first stop and the second stop being located on two adjacent right-angled sides of the plate to be electroplated.

[0024] Beneficial effects: By setting a first stop and a second stop, the present invention enables the plate to be electroplated to be pushed into the electroplating frame by a robotic arm or manually during the placement process, and the two adjacent right-angled sides of the plate to be electroplated to be abutted with the first stop and the second stop respectively, thus positioning the plate to be electroplated without the need for secondary calibration, achieving rapid positioning of the plate to be electroplated.

[0025] In one optional embodiment, the electroplating fixture further includes a conductive sheet, one end of which is fixedly connected to the conductive plate and the other end of which is fixedly connected to the clamping part.

[0026] Beneficial effects: The conductive sheet enables a reliable electrical connection between the conductive plate and the clamping part, ensuring that the power supply connected to the conductive plate can continuously supply current to the workpiece to be electroplated.

[0027] In a second aspect, the present invention also provides an electroplating system, comprising: Electroplating tank; Multiple electroplating fixtures are provided, spaced apart along the length of the electroplating tank.

[0028] Beneficial effects: By setting the above-mentioned electroplating fixture, the plate to be electroplated can always maintain a fixed position during electroplating in the electroplating system. The plate will not shift due to insufficient clamping force, nor will it be damaged due to excessive clamping force. This ensures that the electroplating system can successfully electroplat the plate and improve the electroplating quality. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] In related technologies, spring-spring clamps or stainless steel elastic arm clamps are commonly used to hold sheet metal parts. However, the clamping force of these elastic clamps mainly relies on the elastic deformation of the material itself. Under long-term use and the complex conditions of electroplating operations, the clamping force is prone to attenuation or fluctuation, resulting in unstable clamping force. On the one hand, unstable clamping force can easily cause the sheet metal parts to loosen or shift in the electroplating tank, affecting the electroplating positioning accuracy and operational stability. On the other hand, because the clamping force is uncontrollable, excessive clamping force can easily damage the surface of the sheet metal parts, while insufficient clamping force cannot guarantee a secure clamping, leading to sheet metal parts falling off or incomplete electroplating, seriously affecting product yield and surface quality.

[0034] To solve the above technical problems, the following will be combined with... Figures 1 to 12 The following describes embodiments of the present invention.

[0035] According to an embodiment of the present invention, an electroplating fixture is provided, comprising a first clamping plate 1, a second clamping plate 2, a linkage unit, a counterweight 7, and a clamping unit 8. The first clamping plate 1 is fixedly disposed, and the second clamping plate 2 is rotatably connected to the first clamping plate 1 via a first rotating shaft 3. The linkage unit includes a first connecting rod 401, a second connecting rod 402, and a third connecting rod 403. The first connecting rod 401 has a first position and a second position, and the first connecting rod 401 reciprocates axially to switch between the first and second positions. One end of the first connecting rod 401 is hinged to one end of the second connecting rod 402 via a second rotating shaft 5, and the other end of the second connecting rod 402 is hinged to one end of the third connecting rod 403 via a third rotating shaft 6. The other end of the third connecting rod 403 is connected to the second clamping plate 2. The first rotating shaft 3... The axes of the second rotating shaft 5 and the third rotating shaft 6 are parallel; the counterweight 7 drives the first connecting rod 401 to move from the first position to the second position by its own weight; the clamping unit 8 includes two sets of clamping parts 801, which are respectively fixedly mounted on the first clamping plate 1 and the second clamping plate 2; when the first connecting rod 401 is in the first position, the second clamping plate 2 forms an angle with the first clamping plate 1, and the clamping part 801 is in the open state; when the first connecting rod 401 is in the second position, the second clamping plate 2 rotates around the first rotating shaft 3, the surface of the second clamping plate 2 is parallel to the surface of the first clamping plate 1, and the clamping part 801 closes to clamp the plate to be electroplated.

[0036] In this embodiment, an external force moves the first connecting rod 401 to the first position, forming an angle between the second clamping plate 2 and the first clamping plate 1, causing the two sets of clamping parts 801 to open and place the plate to be electroplated. Then, the weight of the counterweight 7 drives the first connecting rod 401 to fall from the first position to the second position. The angle between the first connecting rod 401 and the second connecting rod 402 changes through the second rotating shaft 5, causing the second connecting rod 402 to move. At the same time, the angle between the second connecting rod 402 and the third connecting rod 403 changes through the third rotating shaft 6, causing the third connecting rod 403 to move. The movement of the third connecting rod 403... The movement causes the second clamping plate 2 to rotate around the first rotating shaft 3, changing the angle between the second clamping plate 2 and the first clamping plate 1 to parallel to each other. This causes the two sets of clamping parts 801 to change from an open state to a closed state, thus clamping the plate to be electroplated. By using the force of the counterweight block 7 itself, the clamping force at the clamping point can be precisely controlled, ensuring that the clamping point does not bear the weight of the plate to be electroplated itself. This provides a stable and uniform clamping force for the plate to be electroplated, ensuring that the clamping force is not too large and will not damage the surface of the plate to be electroplated, thereby ensuring the electroplating quality of the plate to be electroplated.

[0037] In one embodiment, the third link 403 includes a first link 4031 and a second link 4032 that are perpendicular to each other. The end of the first link 4031 is hinged to the second link 402, and the end of the second link 4032 is fixedly connected to the second clamping plate 2. The connecting end of the first link 4031 and the second link 4032 is hinged to the first rotating shaft 3.

[0038] In this embodiment, the third connecting rod 403 is configured as a first rod 4031 and a second rod 4032 that are perpendicular to each other, and the junction of the first rod 4031 and the second rod 4032 is hinged to the first rotating shaft 3. This makes the third connecting rod 403 the medium for driving the second clamping plate 2 to rotate. When the second connecting rod 402 drives the first rod 4031 to rotate around the first rotating shaft 3, the second rod 4032 will also rotate around the first rotating shaft 3, and drive the second clamping plate 2 to rotate. This allows the second clamping plate 2 to open and close with the first clamping plate 1, which can better ensure the stability of the second clamping plate 2 during the opening and closing process, and further ensure that the clamping part 801 can provide a stable clamping force for the plate to be electroplated.

[0039] In one embodiment, the electroplating fixture further includes a conductive plate 9 and a fixing frame 10. A first connecting rod 401 is movably disposed on the conductive plate 9. The clamping part 801 is electrically connected to the conductive plate 9. The fixing frame 10 and the conductive plate 9 together form an electroplating frame. The second clamping plate 2 and the first clamping plate 1 are respectively located on both sides of the electroplating frame.

[0040] In this embodiment, a conductive plate 9 provides a stable current to the clamping part 801, enabling the clamping part 801 to provide a combined function of clamping, positioning, and conducting electricity for the workpiece to be electroplated. Furthermore, the fixing frame 10 and the conductive plate 9 together form an electroplating frame, which on the one hand enhances the overall rigidity of the workpiece to be electroplated, and on the other hand provides a reference surface for clamping the workpiece, thereby ensuring that the workpiece to be electroplated maintains clamping stability under the impact of the electroplating liquid flow after clamping.

[0041] In one embodiment, a guide block 12 is fixedly disposed on the conductive plate 9, and at least a portion of the first connecting rod 401 is slidably disposed inside the guide block 12 along the axial direction.

[0042] In this embodiment, by setting the guide block 12, a guiding function is provided for the movement of the first link 401 between the first position and the second position, ensuring that the first link 401 moves between the first position and the second position along a fixed trajectory, and further ensuring the stability of clamping.

[0043] In one embodiment, each set of clamping parts 801 is provided with a plurality of jaws 802. The jaws 802 on the two sets of clamping parts 801 are arranged in a one-to-one correspondence. Each jaw 802 is provided with a clamping post 8011. The ends of the two clamping posts 8011 of a pair of jaws 802 are arranged opposite to each other. The end of the clamping post 8011 has a hemispherical chuck 8012. When the two sets of clamping parts 801 are closed, the chuck 8012 and the surface of the plate to be electroplated form a point contact.

[0044] In this embodiment, the hemispherical chuck 8012 at the end of the clamping column 8011, together with the clamping structure with the chucks 8012 on the two sets of clamping parts 801 arranged opposite to each other, replaces the traditional line contact or sharp point contact with a continuous curved surface, eliminating the hidden dangers of local indentation, micro-cracks and edge chipping that may be generated on the plate to be electroplated, and avoiding mechanical damage to the plate to be electroplated.

[0045] Furthermore, the hemispherical clamping head 8012, in conjunction with the weight of the counterweight 7 itself, continuously applies a driving force downward along the axial direction of the first connecting rod 401 through its own weight. This force is then transmitted via the hinged transmission of the second rotating shaft 5 and the third rotating shaft 6, converting the weight of the counterweight 7 along the axial direction of the first connecting rod 401 into the rotational clamping force of the second clamping plate 2 around the first rotating shaft 3. The transmission path of the weight of the counterweight 7 is a fixed mechanical structure, ensuring that the weight of the counterweight 7 will not experience force attenuation or fluctuation during transmission. This allows for precise control of the clamping force of the clamping head 8012, ensuring that the clamping head 8012 always maintains the preset clamping force acting on the workpiece to be electroplated, without any force deviation due to changes in usage time or working conditions, thereby achieving the effect of zero breakage during clamping.

[0046] In one embodiment, a first cover plate 101 is fixedly provided on the first clamping plate 1, and a plurality of first electroplating ports 1011 are provided on the first cover plate 101. The plurality of first electroplating ports 1011 are correspondingly provided with a set of clamping parts 801 provided on the first clamping plate 1.

[0047] In this embodiment, by setting a first shield 101, the electric field distribution on the surface of the workpiece to be electroplated can be constrained. The first electroplating port 1011 opened on the first shield 101 can constrain the electric field distribution on the surface of the workpiece to be electroplated while ensuring that the electroplating solution can fully contact the surface of the workpiece to be electroplated, thereby achieving efficient electroplating.

[0048] In one embodiment, a plurality of second cover plates 201 are fixedly provided on the second clamping plate 2, and the plurality of second cover plates 201 are correspondingly provided with a set of clamping parts 801 provided on the second clamping plate 2. A second electroplating port 2011 is provided on the second cover plate 201.

[0049] This embodiment uses a second shield 201 to constrain the electric field distribution on the surface of the workpiece to be electroplated, in conjunction with the first shield 101. Multiple second shields 201 can be used, and their opening angles can be controlled to adjust the electric field distribution on the surface of the workpiece held in each pair of opposing clamping parts 801 in real time. This weakens the peak current density and fills in the valleys, ensuring that the electric field distribution on the surface of the workpiece in each pair of opposing clamping parts 801 remains uniform. This eliminates the defect of thicker edge plating and thinner center plating caused by tip discharge from the point contact of the clamps 8012, ensuring the uniformity of the plating on the surface of the workpiece and improving the efficiency and quality of the electroplating process.

[0050] In one embodiment, a slope is formed on one side of the second baffle 201, and a baffle 11 is provided on the fixing frame 10. A slope is formed on one side of the baffle 11. When the surface of the second clamping plate 2 is parallel to the surface of the first clamping plate 1, the slope of the baffle 11 and the slope of the second baffle 201 abut against each other.

[0051] In this embodiment, the inclined surface of the second shield 201 abuts against the inclined surface of the baffle 11. On the one hand, this restricts the second shield 201 from continuing to move towards the plate after it abuts against the baffle 11, ensuring that the position of the chuck 8012 against the surface of the plate to be electroplated is fixed. On the other hand, this prevents the second shield 201 from causing the chuck 8012 to apply excessive clamping force to the plate, which could damage the plate and improve the accuracy of the clamping force of the chuck 8012.

[0052] In one embodiment, a plurality of flow equalization holes 13 are provided on both the first shield 101 and the second shield 201. The plurality of flow equalization holes 13 on the first shield 101 are arranged around the first electroplating port 1011, and the plurality of flow equalization holes 13 on the second shield 201 are arranged around the second electroplating port 2011.

[0053] In this embodiment, by arranging multiple flow equalization holes 13 around the first electroplating port 1011 and the second electroplating port 2011, it is possible to ensure that the electroplating solution can flow evenly onto the surface of the workpiece to be electroplated, thereby ensuring that a uniform coating can be produced on the surface of the workpiece and further improving the efficiency and quality of the electroplating process.

[0054] In one embodiment, a first stop 14 and a second stop 15 are fixedly disposed on the fixing frame 10, and the first stop 14 and the second stop 15 are respectively located on two adjacent right-angled sides of the plate to be electroplated.

[0055] In this embodiment, by setting a first stop 14 and a second stop 15, the plate to be electroplated can be pushed into the electroplating frame by a robotic arm or manually during the placement process, and the two adjacent right-angled sides of the plate to be electroplated can be made to abut against the first stop 14 and the second stop 15 respectively, thus positioning the plate to be electroplated without the need for secondary calibration, achieving rapid positioning of the plate to be electroplated.

[0056] In one embodiment, the electroplating fixture further includes a conductive sheet 16, one end of which is fixedly connected to the conductive plate 9, and the other end of which is fixedly connected to the clamping part 801.

[0057] In this embodiment, the conductive sheet 16 enables a reliable electrical connection between the conductive plate 9 and the clamping part 801, ensuring that the power supply connected to the conductive plate 9 can continuously supply current to the plate to be electroplated.

[0058] In practical use, this embodiment first uses manual or electric force to drive the first connecting rod 401 to move vertically upward. Then, the cooperation between the first connecting rod 401 and the second rotating shaft 5 applies a force to the upper part of the second connecting rod 402, causing the second connecting rod 402 to move. Through the cooperation between the second connecting rod 402 and the third rotating shaft 6, the first rod body 4031 of the third connecting rod 403 rotates around the first rotating shaft 3. At this time, since the first rod body 4031 and the second rod body 4032 of the third connecting rod 403 form an L-shaped structure, the second rod body of the third connecting rod 403... 4032 drives the second cover plate 201 and the second clamping plate 2 to move away from the fixing frame 10 simultaneously. Under the force of the second clamping plate 2, the clamp 8012 set on the second clamping plate 2 moves away from the clamp 8012 set on the first clamping plate 1, completing the opening of the electroplating fixture in this embodiment. After the electroplating fixture is opened, the plate to be electroplated is pushed into the fixing frame 10 by a robot or manually, and quickly and accurately pushed to the preset position in the fixing frame 10 by the first stop 14 and the second stop 15, that is, one right-angled edge of the plate to be electroplated is attached to the upper part of the two second stops 15. The other adjacent right-angled side is attached to the first stop 14, achieving seamless contact between the two adjacent right-angled sides of the plate to be electroplated and the first stop 14 and the second stop 15, thereby completing the positioning of the plate to be electroplated. After the plate to be electroplated is placed, the upward force applied to the first connecting rod 401 is released. Since the counterweight 7 always applies downward pressure to the first connecting rod 401 through its gravity, and since the upward force on the first connecting rod 401 disappears, under the action of the gravity of the counterweight 7, the first connecting rod 401 moves downward, driving the second connecting rod 402, the third rotating shaft 6, and the second... The three-link rod 403 rotates and resets, thereby driving the second shielding plate 201 and the second clamping plate 2 to reset. The clamp 8012, driven by the second clamping plate 2, clamps the plate to be electroplated, thus completing the clamping and shielding work of the plate to be electroplated. Finally, after the clamping and shielding work of the plate to be electroplated is completed, the electroplating work begins. The current is conducted to the plate to be electroplated through the external power supply, the conductive plate 9, the conductive sheet 16, the clamping part 801, and the clamp 8012. The first shielding plate 101 and the second shielding plate 201 cooperate with each other to constrain the electric field distribution and achieve uniform metal deposition.

[0059] According to an embodiment of the present invention, another aspect provides an electroplating system, including an electroplating tank and an electroplating fixture of the previous embodiment, wherein a plurality of electroplating fixtures are spaced apart in the electroplating tank along the length direction of the electroplating tank.

[0060] This embodiment, by setting the aforementioned electroplating fixture, ensures that the plate to be electroplated remains in a fixed position during electroplating in the electroplating system. Insufficient clamping force will prevent the plate from shifting under the flow of the electroplating solution, while excessive clamping force will prevent damage to the surface of the plate. This ensures the electroplating system can successfully electroplat the plate, thereby improving the electroplating quality.

[0061] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
