Description

Technical Field

[0001] The invention relates to the technical field of electroplating, and in particular to a conductive fixing mechanism used for electroplating. Background Art

[0002] In the related technology, the electroplated rod refers to a plated rod with a layer of metal elements of 20μm-30μm thickness formed on the surface of the hard optical axis through electroplating. It is suitable for use with linear bearings in the automation industry. During electroplating, the plated rod is generally clamped by a conductive clamp, and the existing conductive clamps are generally of the clamping plate type, which have line contact with the cylindrical plated rod, small contact area, poor stability, and easy to produce poor contact. In addition, the current carrying capacity is poor, the conductivity is uneven, and it is easy to cause electric shock, damage the product surface, and destroy the coating. Summary of the invention

[0003] In view of this, the present invention provides a conductive fixing mechanism for electroplating to solve the problems in the related art of small contact area, poor current carrying capacity, uneven conductivity, easy to cause electric shock, damage to product surface, and destruction of the coating.

[0004] In a first aspect, the present invention provides a conductive fixing mechanism for electroplating, comprising:

[0005] A fixing seat, formed with a mounting hole;

[0006] A plurality of clamping members, each of which is disposed in the mounting hole and arranged at intervals along the circumference of the mounting hole, and each of the clamping members is slidably connected to the fixing seat along a first direction, and a conductive member is installed on one side of each clamping member facing the center of the mounting hole;

[0007] A linkage device, movably connected to all the clamping members, respectively, and used to control all the clamping members to slide synchronously relative to the fixing seat, so that the conductive fixing mechanism switches between a clamping state and a loosened state;

[0008] Wherein, in the clamped state, the conductive member on each clamp is attached to the outer surface of the plating rod; in the loosened state, each clamp is away from the plating rod.

[0009] Beneficial effects: The conductive fixing mechanism of the present invention solves the problems of small contact area, poor stability, easy to produce poor contact and limited current capacity of traditional clamps by virtue of its multi-point contact, synchronous action and wide adaptability design, making the electroplating process of the plating rod more efficient and reliable and the quality of the finished product higher.

[0010] In an optional embodiment, the linkage device includes a driving member and a circular chuck, the chuck is rotatably mounted on the fixed seat, the driving member is fixed on the fixed seat and its driving end is drivingly connected to the chuck;

[0011] Each of the clamping members is slidably connected to the chuck along the second direction, and the driving member is used to drive the chuck to rotate, so that all the clamping members move synchronously along the radial direction of the mounting hole.

[0012] Beneficial effects: All clamps are controlled by the same chuck, ensuring that they can open and close in complete synchronization, avoiding the problem of plating rod deflection or excessive local pressure caused by the asynchrony of individual clamps. In addition, the chuck design provides a stable rotating platform, making the movement of the clamps more stable, improving the reliability and durability of the entire system.

[0013] In an optional embodiment, one of the first direction and the second direction is a radial direction of the mounting hole, and the other is an arc direction gradually moving away from or approaching the mounting hole.

[0014] Beneficial effects: The first direction is radial, which controls the opening and closing movement of the clamp bracket in the radial direction; the second direction is an arc direction with a radial component, which ensures that the clamp gradually approaches or moves away from the center of the mounting hole while moving along the circular path, thereby providing a more stable and uniform clamping force, improving the conductivity and protecting the coating.

[0015] In an optional embodiment, the chuck is provided with a plurality of linkage holes extending along the second direction, each of the linkage holes is provided with a slidable linkage member, and the plurality of linkage members are fixed on the plurality of clamping members in a one-to-one correspondence.

[0016] Beneficial effects: The design of the linkage hole ensures the precise moving path of the clamping parts, thereby achieving high-precision clamping and release of the plating rod. And because all the clamping parts are controlled by the same chuck, the coordination of the linkage hole and the linkage parts ensures that they can open and close in complete synchronization, avoiding problems caused by the asynchrony of individual clamping parts.

[0017] In an optional embodiment, the fixing seat is provided with a plurality of slide rails extending along the first direction, each of the slide rails is provided with a slidable slider, and the plurality of sliders are fixed on the plurality of clamping members in a one-to-one correspondence.

[0018] Beneficial effects: The design of the slide rail and slider ensures the precise radial movement path of the clamping part, achieving high-precision clamping and release of the plating rod. At the same time, the slide rail limits the movement direction of the clamping part, reduces unnecessary lateral displacement, and improves the operating stability and reliability of the system.

[0019] In an optional embodiment, the chuck is provided with a plurality of limiting holes extending along the rotation direction thereof, each of the limiting holes is provided with a slidable first limiting member, and the limiting member is fixed on the fixing seat.

[0020] Beneficial effect: The design of the limiting hole and the first limiting member on the chuck ensures the axial stability of the chuck during the rotation process.

[0021] In an optional embodiment, at least one group of second limit members is provided on the fixed seat, each group of second limit members includes two second limit members, and the two second limit members of the same group are respectively arranged on opposite sides of the chuck and are respectively slidably connected to the outer peripheral surface of the chuck.

[0022] Beneficial effect: This design ensures that the chuck will neither move axially nor deviate radially during rotation, thereby maintaining the high precision and stability of the system.

[0023] In an optional embodiment, a “V”-shaped mounting groove is formed on one side of each clamping member facing the center of the mounting hole.

[0024] Beneficial effects: When the clamping piece clamps the plating rod, the conductive piece in the "V"-shaped mounting groove will deform, increasing the contact area with the plating rod, thereby improving the conductive efficiency, reducing the contact resistance, and avoiding electric shock and plating damage. In addition, the "V"-shaped structure can better adapt to the different curvature changes on the surface of the plating rod, ensuring that good contact can be maintained even when there are irregular shapes on the surface of the plating rod.

[0025] In an optional embodiment, the conductive member is a flexible conductive belt, both sides of which are respectively fixed on the two side edges of the mounting groove, and a gap is formed between the flexible conductive belt and the bottom of the mounting groove to allow the flexible conductive belt to deform.

[0026] Beneficial effects: The flexible conductive tape is used to provide good conductivity and flexibility, ensuring that it can be properly deformed when clamping the plating rod to adapt to the surface of the plating rod and increase the contact area.

[0027] In an optional embodiment, a conductive busbar is further provided on the other side of the fixing seat opposite to the chuck, and the conductive member on each of the clamping members is electrically connected to the conductive busbar via a flexible conductive connecting belt.

[0028] Beneficial effects: On the one hand, the current transmission is centrally managed through the conductive busbar, which ensures the stability and efficiency of current transmission and reduces contact resistance and current loss. On the other hand, the design of the flexible conductive connecting belt enables it to adapt to the radial movement of the clamping piece, maintain a stable electrical connection, and work normally even in complex working environments.

[0044] A conductive fixing mechanism for electroplating provided by the present invention will be described below with reference to the accompanying drawings.

[0045] like Figures 1 to 6 As shown, the conductive fixing mechanism for electroplating according to an embodiment of the present invention includes a fixing seat 1, a plurality of clamping members 2 and a linkage device.

[0046] The fixing seat 1 is formed with a mounting hole 11, and the mounting hole 11 is used to fix the plating rod 3 required for electroplating. A plurality of clamping members 2 are arranged in the mounting hole 11 and are arranged at intervals along the circumference of the mounting hole 11, and each clamping member 2 is slidably connected to the fixing seat 1 along a first direction (for example, the radial direction of the mounting hole 11), and a conductive member 21 is installed on one side of each clamping member 2 facing the center of the mounting hole 11.

[0047] The linkage device is movably connected to all the clamping members 2, and is used to control all the clamping members 2 to slide synchronously relative to the fixing seat 1, so that the conductive fixing mechanism switches between a clamping state and a loose state. In the clamping state, the conductive member 21 on each clamping member 2 is attached to the outer surface of the plating rod 3; in the loose state, each clamping member 2 is away from the plating rod 3.

[0048] Based on the above description, the structure of the conductive fixing mechanism is first described in detail as follows:

[0049] The fixing base 1 is the basic component of the entire conductive fixing mechanism, which not only provides mechanical support, but also integrates all other key components. A mounting hole 11 is formed on the fixing base 1, which is specially designed to accommodate and fix the plating rod 3 required in the electroplating process. The size and shape of the mounting hole 11 must accurately match the plating rod 3 to ensure that the plating rod 3 can be accurately positioned in the center and remain stable during the entire electroplating process.

[0050] A plurality of clamping members 2 are evenly distributed inside the mounting hole 11 and arranged at intervals along the circumference of the mounting hole 11. Each clamping member 2 is connected to the fixing seat 1 through a specific sliding mechanism, and the above connection method allows the clamping member 2 to move along a first direction (for example, the radial direction of the mounting hole 11). Specifically, the clamping member 2 can slide inward or outward in the radial direction to adapt to plating rods 3 of different diameters and ensure that it can closely fit the surface of the plating rod 3 in the clamped state.

[0051] Each clamping member 2 is provided with a conductive member 21 on one side facing the center of the mounting hole 11, which is usually made of a material with good conductivity and flexibility, such as a copper braid. When the clamping member 2 moves to a position close to the plating rod 3, the conductive member 21 directly contacts the surface of the plating rod 3, providing a stable current transmission path, while reducing contact resistance and avoiding damage to the plating layer.

[0052] It can be understood that the design of the clamping members 2 allows them to move radially in the fixed seat 1 to accommodate plating rods 3 of different diameters, and provide a stable current transmission path through the conductive member 21. In order to coordinate the actions of all the clamping members 2 and ensure that they can synchronously approach or move away from the plating rod 3, thereby achieving the clamping or release of the plating rod 3, the present invention designs a linkage device. The linkage device is movably connected to each clamping member 2 and can drive the clamping member 2 to slide synchronously. This synchronous motion mechanism ensures that no matter how the position of the plating rod 3 changes, the clamping member 2 can maintain consistent movement, thereby maintaining good conductivity and stability.

[0053] Specifically, the linkage device is connected to each clamping member 2 in a movable manner, so that all the clamping members 2 can be controlled to perform consistent sliding movement relative to the fixing seat 1. The design of the linkage device ensures that the clamping members 2 can move inward or outward synchronously, so that the conductive fixing mechanism can smoothly switch between the "clamping state" and the "relaxing state".

[0054] For example, in the clamped state, the linkage device drives the clamping members 2 to slide inward until the conductive member 21 on each clamping member 2 completely fits the outer surface of the plating rod 3 to form a firm electrical connection. In the loosened state, the linkage device guides the clamping members 2 to slide outward, keeping them away from the plating rod 3, so that the plating rod 3 can be easily put in or taken out, while also reducing unnecessary mechanical wear and electrical loss.

[0055] Further, based on the specific introduction of the above structure, the specific working principle and working process of the conductive fixing mechanism of the present invention are as follows:

[0056] When the plating rod 3 needs to be fixed, the linkage device is started, which drives all the clamps 2 to move toward the center of the mounting hole 11 at the same time. Since the clamps 2 are slidably connected to the fixing seat 1 along a first direction (for example, the radial direction of the mounting hole 11), the clamps 2 gradually approach the plating rod 3 under the action of the linkage device. As the clamps 2 approach, the conductive member 21 (for example, a copper braid) mounted thereon begins to fit the surface of the plating rod 3. At this time, because the number of the clamps 2 is large and evenly distributed around the mounting hole 11, it can be ensured that the plating rod 3 is evenly clamped, and no deflection or excessive local pressure will occur. In addition, if the conductive member 21 adopts a flexible conductive belt, the flexible conductive belt will be deformed under the action of the clamping force, increasing the contact area with the plating rod 3, thereby improving the conduction efficiency, reducing the contact resistance, preventing electric shock, and protecting the quality of the coating.

[0057] When the electroplating operation is completed, or when there is no need to clamp the plating rod 3 in the preparation stage, the linkage device reverses and causes all the clamps 2 to move outward synchronously, away from the plating rod 3. The purpose of this is to allow the plating rod 3 to be easily put in or taken out, while also avoiding unnecessary mechanical wear and electrical loss. In this state, the clamps 2 no longer apply any pressure to the plating rod 3, so the plating rod 3 is in a completely free state without any obstacles. In this way, the conductive fixing mechanism can flexibly switch between the clamped state and the loosened state, which not only meets the process requirements but also ensures the safety and durability of the equipment.

[0058] In the related art, the electroplated rod 3 refers to a plated rod 3 on the surface of a hard optical axis that is electroplated to form a layer of metal elements with a thickness of 20μm-30μm. It is suitable for use in the automation industry and in conjunction with linear bearings. During electroplating, the plated rod 3 is generally clamped by a conductive clamp, and the existing conductive clamps are generally of a clamping plate type, which has line contact with the cylindrical plated rod 3, has a small contact area, poor stability, and is prone to poor contact. It also has poor current-carrying capacity, uneven conductivity, and is prone to electric shock, damaging the product surface and destroying the coating.

[0059] Therefore, in order to solve the technical defects existing in the above-mentioned related technologies, the present invention provides a conductive fixing mechanism for electroplating, which uses a linkage device to control multiple clamping members 2 to synchronously move away from or approach the plating rod 3 required for electroplating, so that the plating rod 3 can be clamped and fixed by multiple clamping members 2 in a surrounding form. Compared with the related technologies, it has at least the following advantages:

[0060] (1) Increase contact area and improve conductivity: By arranging multiple clamps 2 at intervals along the circumference of the mounting hole 11, each clamp 2 can form contact with the plating rod 3. Compared with the line contact or point contact of the traditional clamp, this multi-point contact method significantly increases the total contact area, thereby reducing the contact resistance and improving the current transmission efficiency.

[0061] (2) Uniformly apply clamping force to ensure stability: All clamping parts 2 slide synchronously under the action of the linkage device, which can form uniformly distributed pressure around the plating rod 3. This not only ensures that the plating rod 3 will not deviate or vibrate during the entire electroplating process, but is also particularly suitable for processing large-sized or complex-shaped parts, improving the stability and reliability of the process.

[0062] (3) Avoid poor contact and improve product quality: Due to the multi-point contact design, even if there are curvature changes or other irregular shapes on the surface of the plating rod 3, the mechanism can ensure sufficient contact points and effectively prevent the occurrence of poor contact. Uniform and extensive contact helps maintain a stable current supply, thereby improving the quality of the final product.

[0063] (4) Enhanced current capacity and electroplating efficiency: A larger contact area means a higher current capacity because the current can be more widely distributed on the surface of the plating rod 3. This not only speeds up the electroplating speed, but also makes the coating more uniform and consistent, improving production efficiency and product consistency.

[0064] (5) Strong adaptability and wide application range: The conductive fixing mechanism can be adjusted according to the plating rods 3 of different diameters and shapes, and can be flexibly adapted through the radial sliding of the clamping member 2. This feature makes it suitable for various types of electroplating operations, broadens the scope of application, and meets different industrial needs.

[0065] In summary, the conductive fixing mechanism of the present invention solves the problems of small contact area, poor stability, easy to produce poor contact and limited current capacity of traditional clamps by virtue of its multi-point contact, synchronous action and wide adaptability design, making the electroplating process of the plating rod 3 more efficient and reliable and the quality of the finished product higher.

[0066] It should be noted that in the conductive fixing mechanism of the present invention, the linkage device can adopt a variety of structures to achieve the synchronous movement of all the clamping members 2, and the present invention does not impose any special restrictions here, as long as the linkage device can achieve the synchronous movement of all the clamping members 2. For easy understanding, some specific embodiments are given below for demonstration.

[0067] For example, the linkage device includes a driving member 4 and a chuck 5, and the chuck 5 is a circular ring structure. When the driving member 4 drives the chuck 5 to rotate, the wheel on the clamping member 2 slides along the track of the limiting hole 52, forcing the clamping member 2 to move toward the center or outside of the mounting hole 11.

[0068] For another example, the linkage device includes a motor and a screw transmission device, and the screw transmission device includes a screw and a nut. The screw can be single or multiple, radially arranged around the mounting hole 11, and each screw is equipped with a corresponding nut, which is fixedly connected to the clamping member 2. The motor drives the screw to rotate through a gear box or other reduction device, and the nut moves along the axis of the screw, driving the clamping member 2 to slide inward or outward.

[0069] For another example, the linkage device is a gear rack linkage structure. Specifically, a rack is provided on one side of each clamping member 2, and all the racks are meshed with a common large gear. The large gear is located near the center of the mounting hole 11 and is driven by a motor or a manually operated hand wheel. When the large gear rotates, all the racks move radially at the same time.

[0070] For example, the linkage device is an electromagnetically driven linkage structure, specifically, an electromagnet is used as a driving element, and each clamping member 2 is equipped with a small electromagnet, which attracts or repels metal parts (such as an armature) through electromagnetic force, thereby realizing the opening and closing action of the clamping member 2. All electromagnets can be managed uniformly by a central controller, and the action sequence and strength of each clamping member 2 can be adjusted as needed.

[0071] In summary, the above linkage structures have their own advantages and disadvantages, and the choice depends on the specific usage scenario and technical requirements. For example, for applications that require high precision and stability, the drive member 4 drives the chuck 5 to rotate and the gear rack type is more suitable; if you pursue fast response and reduce mechanical wear, you can choose the electromagnetic drive type.

[0072] For the convenience of description, the conductive fixing mechanism of the present invention will be described in detail below by taking the linkage device including the driving member 4 and the chuck 5 as an example without losing generality.

[0073] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the linkage device includes a driving member 4 and a ring-shaped chuck 5, the chuck 5 is rotatably mounted on the fixed seat 1, the driving member 4 is fixed on the fixed seat 1 and its driving end is transmission-connected to the chuck 5.

[0074] Each clamping member 2 is slidably connected to the chuck 5 along the second direction, and the driving member 4 is used to drive the chuck 5 to rotate, so that all the clamping members 2 move synchronously along the radial direction of the mounting hole 11 .

[0075] In this embodiment, the driving member 4 is fixed on the fixing seat 1 as a power source, and is connected to the chuck 5 through its driving end. The driving member 4 can be a cylinder, a motor or other power device capable of generating rotation or linear motion, and the present invention does not make any special restrictions here.

[0076] The chuck 5 is a circular ring structure, which is rotatably mounted on the fixed seat 1. The chuck 5 not only plays a supporting role, but also serves as a common moving platform for all the clamping members 2. Each clamping member 2 is slidably connected to the chuck 5 along a second direction (usually an arc direction gradually away from or close to the center of the mounting hole 11), that is, the clamping member 2 can slide in a specific track on the chuck 5, and the track can be designed to be arc-shaped to adapt to the rotation of the chuck 5.

[0077] Furthermore, the specific working principle and process are as follows: when the driving member 4 is started, it transmits force to the chuck 5 through the transmission connection, so that the chuck 5 rotates around the axis of the mounting hole 11. As the chuck 5 rotates, since there is a sliding connection between the clamping member 2 and the chuck 5 in the second direction, and there is also a sliding connection between the clamping member 2 and the fixing seat 1 in the first direction, based on the sliding connection structure in the two directions and the rotation of the chuck 5 itself, the clamping member 2 is forced to move synchronously along the preset trajectory (i.e., the radial direction of the mounting hole 11).

[0078] For example, when the chuck 5 rotates in a certain direction, the clamping member 2 will move toward the center of the mounting hole 11 under its guidance until the conductive member 21 on each clamping member 2 is closely attached to the surface of the plating rod 3 to form a firm electrical connection. Conversely, when the chuck 5 rotates in the opposite direction, the clamping member 2 is guided to move outwards away from the plating rod 3, thereby releasing the plating rod 3 and making it free for easy insertion or removal.

[0079] In this way, all the clamps 2 are controlled by the same chuck 5, ensuring that they can open and close in full synchronization, avoiding the problem of deflection of the plating rod 3 or excessive local pressure caused by the asynchrony of individual clamps 2. In addition, the design of the chuck 5 provides a stable rotating platform, making the movement of the clamps 2 more stable, and improving the reliability and durability of the entire system.

[0080] In summary, this linkage device design based on the driving member 4 and the annular chuck 5 cleverly utilizes the concept of converting rotational motion into radial sliding, realizes the synchronous movement of all clamping members 2, and provides a strong guarantee for stable conductivity in the electroplating process.

[0081] like Figure 2 and Figure 5 As shown, further, one of the first direction and the second direction is a radial direction of the mounting hole 11 , and the other is an arc direction gradually moving away from or approaching the mounting hole 11 .

[0082] It should be explained that the first direction is the radial direction of the mounting hole 11 and the second direction is the arc direction gradually away from or close to the mounting hole 11 as an example for explanation:

[0083] The first direction refers to the direction from the center of the mounting hole 11 to the position of the clamping member 2, or the opposite direction. The radial movement refers to the movement along this straight line, that is, directly approaching or moving away from the center of the mounting hole 11. In the conductive fixing mechanism, the radial movement is used to control the radial sliding of the clamping member 2, thereby achieving the clamping or release of the plating rod 3.

[0084] The second direction is a tangential motion with a radial component. This motion not only moves the clamping members 2 along a circular path, but also gradually changes their distance from the center of the mounting hole 11 in the process. Specifically, it is not a strict tangential motion, but a composite motion that includes a radial component, causing the clamping members 2 to gradually approach or move away from the center of the mounting hole 11 while moving along the circular path. It can be understood that in the conductive fixing mechanism of the present invention, this arc-shaped motion ensures that the clamping members 2 can be smoothly and evenly distributed on a concentric circle while maintaining good contact with the surface of the plating rod 3.

[0085] Specifically, the working process is as follows: when the driving member 4 (such as a cylinder) is started, it rotates the chuck 5 around the axis of the mounting hole 11 through the transmission mechanism. During the rotation of the chuck 5, the clamping member 2 undergoes two types of sliding: (1) Sliding in the arc direction relative to the chuck 5: the clamping member 2 moves along an arc path, which changes their position relative to the chuck 5. Since this sliding includes a radial component, it actually guides the clamping member 2 to gradually approach or move away from the center of the mounting hole 11. (2) Radial sliding relative to the fixed seat 1: Since the clamping member 2 can only slide along the slide rail 12 (first direction), the result of this arc sliding is that they are forced to move in the radial direction. The slide rail 12 limits the clamping member 2 to slide only in the radial direction, ensuring that its final moving direction is radial.

[0086] All the clamps 2 are affected by the same force, and because they all follow the same compound motion law, it is possible to ensure that all the clamps 2 open and close synchronously, ensuring that the plating rod 3 always maintains a uniform force state throughout the entire electroplating process.

[0087] Finally, the compound motion of the clamping member 2 is converted into precise movement along the radial direction of the mounting hole 11, thereby clamping or releasing the plating rod 3. When the chuck 5 rotates in a certain direction, the clamping member 2 moves toward the center of the mounting hole 11 to form a firm electrical connection; when the chuck 5 rotates in the opposite direction, the clamping member 2 moves away from the plating rod 3 and enters a loose state.

[0088] In summary, in the above embodiment, the first direction is radial, controlling the opening and closing action of the clamp bracket in the radial direction; the second direction is an arc direction with a radial component, ensuring that the clamping member 2 gradually approaches or moves away from the center of the mounting hole 11 while moving along the circumferential path, thereby providing a more stable and uniform clamping force, improving the conductive performance and protecting the plating layer. This method cleverly combines the movement in the radial and arc directions, so that even when processing plating rods 3 of different sizes or complex shapes, it can maintain good contact effects and stable current transmission.

[0089] like Figure 1 and Figure 2As shown, according to some embodiments of the present invention, the chuck 5 is provided with a plurality of linkage holes 51 extending along the second direction, each linkage hole 51 is provided with a slidable linkage member 6, and the plurality of linkage members 6 are fixed on the plurality of clamping members 2 in a one-to-one correspondence.

[0090] In this way, the design of the linkage hole 51 ensures the precise moving path of the clamping member 2, thereby achieving high-precision clamping and releasing of the plating rod 3. And because all the clamping members 2 are controlled by the same chuck 5, the coordination of the linkage hole 51 and the linkage member 6 ensures that they can open and close in complete synchronization, avoiding problems caused by the asynchrony of individual clamping members 2.

[0091] like Figure 1 and Figure 2 As shown, further, a plurality of linkage holes 51 are symmetrically distributed along the circumference of the chuck 5 , and each linkage hole 51 has the same shape and size, and each linkage hole 51 extends in an arc direction gradually away from or close to the mounting hole 11 .

[0092] In this way, since the linkage holes 51 are symmetrically distributed along the circumference of the chuck 5, and each linkage hole 51 extends in an arc direction gradually away from or close to the center of the mounting hole 11, when the chuck 5 rotates, all the clamping members 2 will move synchronously along the path of these linkage holes 51. This ensures that no matter whether the clamping members 2 are contracted inwardly or expanded outwardly, they are always located on a concentric circle with the center of the mounting hole 11 as the center, thereby reducing the risk of deflection of the plating rod 3 or excessive local pressure due to inconsistent positions of the clamping members 2.

[0093] like Figure 6 As shown, further, the linkage member 6 includes a linkage rod 61 and a sliding wheel 62, the linkage rod 61 is fixed on the clamping member 2, the top of the linkage rod 61 is provided with a sliding wheel 62 rotatable along the central axis of the linkage rod 61, and the sliding wheel 62 is slidably fitted in the linkage hole 51. In this way, the free rotation characteristic of the sliding wheel 62 reduces friction and improves the operational stability and reliability of the entire system.

[0094] According to some embodiments of the present invention, a plurality of slide rails 12 extending along a first direction are disposed on the fixing seat 1, a slidable slider 24 is disposed on each slide rail 12, and the plurality of sliders 24 are fixed on the plurality of clamping members 2 in a one-to-one correspondence.

[0095] In this way, the design of the slide rail 12 and the slider 24 ensures the precise radial movement path of the clamp 2, and realizes high-precision clamping and release of the plating rod 3. At the same time, the slide rail 12 limits the movement direction of the clamp 2, reduces unnecessary lateral displacement, and improves the operational stability and reliability of the system.

[0096] like Figure 5As shown, further, a plurality of slide rails 12 are symmetrically distributed along the outer circumference direction of the mounting hole 11, and each slide rail 12 has the same shape and size, and each slide rail 12 extends along the radial direction of the mounting hole 11. In this way, the symmetrically distributed slide rails 12 make all the clamping members 2 always on a concentric circle coinciding with the center of the mounting hole 11, thereby reducing the risk of deflection of the plating rod 3 or excessive local pressure due to inconsistent positions of the clamping members 2.

[0097] like Figure 6 As shown, further, the slider 24 and the linkage member 6 are both fixed on the clamping bracket 23 , and the clamping bracket 23 is fixed to the clamping member 2 for supporting and fixing the clamping member 2 .

[0098] In this way, the clamping bracket 23 provides a solid support for the entire system, reduces shaking and instability during movement, and improves the operational stability and reliability of the system. In addition, the slider 24 and the linkage 6 are integrated on the clamping bracket 23, which simplifies the assembly process and enhances the compactness and overall performance of the system.

[0099] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the chuck 5 is provided with a plurality of limiting holes 52 extending along the rotation direction thereof, and each limiting hole 52 is provided with a slidable first limiting member 7, which is fixed on the fixing seat 1. In this way, the limiting holes 52 provide a sliding path for the first limiting member 7 and ensure that the chuck 5 remains axially stable during rotation.

[0100] like Figure 5 As shown, further, the first limiting member 7 includes a first limiting rod 71 and a first limiting wheel 72, the first limiting rod 71 is fixed on the fixing seat 1, the top of the first limiting rod 71 is provided with a first limiting wheel 72 rotatable along the central axis of the first limiting rod 71, and the first limiting wheel 72 is slidably fitted in the first limiting hole 52. In this way, the sliding fit of the first limiting wheel 72 in the limiting hole 52 reduces the axial shaking of the chuck 5, and improves the operational stability and reliability of the system.

[0101] Preferably, the plurality of limiting holes 52 are evenly distributed along the circumference of the chuck 5 , thereby ensuring the balance and stability of the chuck 5 during rotation, and further enhancing the overall performance of the system.

[0102] As described above, through the design of the limiting hole 52 and the first limiting member 7 on the chuck 5, the conductive fixing mechanism of the present invention not only ensures the axial stability of the chuck 5 during rotation, but also realizes the smooth rotation of the chuck 5 through the sliding cooperation of the first limiting wheel 72.

[0103] like Figure 1 and Figure 2As shown, according to some embodiments of the present invention, at least one group of second stoppers 8 is provided on the fixing seat 1, each group of second stoppers 8 includes two second stoppers 8, and the two second stoppers 8 in the same group are respectively arranged on opposite sides of the chuck 5 and are respectively slidably connected to the outer peripheral surface of the chuck 5. In this way, the chuck 5 is ensured to maintain axial stability during rotation and its radial deviation is limited, thereby maintaining the accuracy and stability of the entire system.

[0104] like Figure 5 As shown, further, the second limiting member 8 includes a second limiting rod 81 and a second limiting wheel 82. The second limiting rod 81 is fixed on the fixed seat 1. The top of the second limiting rod 81 is provided with a second limiting wheel 82 rotatable along the central axis of the second limiting rod 81. The second limiting wheel 82 forms a limiting slot 83. The outer periphery of the chuck 5 is slidably fitted in the limiting slot 83.

[0105] In summary, on the one hand, the first limiting rod 71 and the first limiting wheel 72 ensure the axial stability of the chuck 5. The slider 24 and the slide rail 12 ensure the precise radial movement of the clamping member 2; on the other hand, the second limiting rod 81 and the second limiting wheel 82 (with the limiting slot 83) ensure the axial and radial stability of the chuck 5 during rotation, and the outer periphery of the chuck 5 slides in the limiting slot 83, ensuring the coordinated operation and high efficiency of the entire system.

[0106] This design ensures that the chuck 5 will neither move axially nor deviate radially during rotation, thereby maintaining the high precision and stability of the system.

[0107] like Figure 6 As shown, according to some embodiments of the present invention, a “V”-shaped mounting groove 22 is formed on one side of each clamping member 2 facing the center of the mounting hole 11 .

[0108] In this way, when the clamping member 2 clamps the plating rod 3, the conductive member 21 in the "V"-shaped mounting groove 22 will deform, increasing the contact area with the plating rod 3, thereby improving the conductive efficiency, reducing the contact resistance, and avoiding electric shock and coating damage.

[0109] In addition, the “V”-shaped structure can better adapt to the different curvature changes on the surface of the plating rod 3, ensuring that a good contact effect can be maintained even when there are irregular shapes on the surface of the plating rod 3.

[0110] Furthermore, the conductive member 21 is a flexible conductive belt, both sides of which are fixed on both sides of the groove edge of the installation groove 22, and a gap is formed between the flexible conductive belt and the groove bottom of the installation groove 22 to allow the flexible conductive member 21 to deform.

[0111] In this embodiment, the flexible conductive tape is used to provide good conductivity and flexibility, ensuring that it can be properly deformed when the plating rod 3 is clamped, so as to adapt to the surface of the plating rod 3 and increase the contact area.

[0112] The two sides of the flexible conductive belt are respectively fixed on the two side groove edges of the mounting groove 22 to ensure that it will not slide or fall off during use. It can be understood that this fixing method not only ensures the position stability of the conductive belt, but also allows it to undergo necessary deformation in the middle part to adapt to the shape change of the plating rod 3.

[0113] It should also be pointed out that a certain gap is formed between the flexible conductive belt and the bottom of the mounting groove 22. The above gap allows the conductive belt to deform when clamping the plating rod 3 without being excessively restricted, ensuring that the conductive belt can fully fit the surface of the plating rod 3 during the clamping process, increase the contact area, improve the conductivity, and reduce potential damage to the coating.

[0114] For example Figure 6 As shown, a "V"-shaped mounting groove 22 is provided on the side wall of the clamping member 2, and a copper braided belt (also known as a flexible conductive belt) is fixed at the "V"-shaped mounting groove 22 structure. When the clamping member 2 clamps the plating rod 3, the copper braided belt will deform under extrusion, thereby increasing the contact area with the plating rod 3, reducing electric shock injuries, and avoiding damage to the product surface resulting in destruction of the plating layer. The stability is good and poor contact will not occur. In addition, multiple clamping members 2 and copper braided belts are clamped on the plating rod 3, with uniform conductivity and strong current carrying capacity.

[0115] like Figure 3 and Figure 4 As shown, according to some embodiments of the present invention, a conductive bus 91 is further provided on the other side of the fixing seat 1 opposite to the chuck 5 , and the conductive member 21 on each clamping member 2 is electrically connected to the conductive bus 91 via a flexible conductive connecting belt 92 .

[0116] Thus, on the one hand, the current transmission is centrally managed through the conductive bus 91, ensuring the stability and efficiency of the current transmission and reducing the contact resistance and current loss. On the other hand, the design of the flexible conductive connecting belt 92 enables it to adapt to the radial movement of the clamp 2, maintain a stable electrical connection, and work normally even in a complex working environment.

[0117] At the same time, the design of the flexible conductive connecting strip 92 and the conductive busbar 91 simplifies the structure of the system, reduces the failure rate, and facilitates daily maintenance and repair.

[0118] A specific embodiment of the conductive fixing mechanism of the present invention is given below with reference to the accompanying drawings.

[0119] like Figures 1 to 6As shown, a mounting hole 11 is provided on the fixing seat 1 for accommodating and fixing the plating rod 3. A plurality of slide rails 12 are evenly distributed around the mounting hole 11. Each clamping member 2 is fixed on the slide rail 12 by a slider 24 to ensure that the clamping member 2 can only slide along the radial direction (first direction) of the mounting hole 11. A "V"-shaped mounting groove 22 is formed on one side of each clamping member 2 facing the center of the mounting hole 11, and a flexible conductive belt is installed in the groove. The two sides of the flexible conductive belt are respectively fixed on the two side groove edges of the mounting groove 22, and a certain distance is left between the bottom of the mounting groove 22 to allow it to deform.

[0120] The chuck 5 is rotatably mounted on the fixed seat 1. The chuck 5 is provided with a plurality of limiting holes 52 extending along the rotation direction thereof, and a slidable first limiting member 7 is provided in each limiting hole 52. The first limiting member 7 includes a first limiting rod 71 and a rotatable first limiting wheel 72 provided on the top, and the first limiting wheel 72 is embedded in the limiting hole 52 to ensure that the chuck 5 maintains axial stability during rotation. In addition, the chuck 5 is also provided with a plurality of linkage holes 51 extending along the second direction (arc direction), and a slidable linkage member 6 is provided in each linkage hole 51. The linkage member 6 includes a linkage rod 61 and a rotatable sliding wheel 62 provided on the top, and the sliding wheel 62 is embedded in the linkage hole 51 to ensure that the clamping member 2 can move according to the predetermined path.

[0121] A cylinder is also provided on the fixing seat 1, and the rear cover of the cylinder is rotatably connected to the fixing seat 1 through the clamping bracket 23. The piston rod of the cylinder is rotatably connected to a cylinder connecting rod, and the cylinder connecting rod is fixed at the edge of the chuck 5. The piston rod of the cylinder moves to push the cylinder connecting rod to move, thereby driving the chuck 5 to rotate. Since all the clamping members 2 are connected to the chuck 5 through the sliding wheel 62 in the linkage hole 51, they will respond to the rotation of the chuck 5 synchronously.

[0122] As the chuck 5 rotates, the sliding wheel 62 in the linkage hole 51 is forced to slide along the arc path of the linkage hole 51. Since the sliding wheel 62 is connected to the linkage rod 61, and the linkage rod 61 is fixed on the clamping bracket 23, this sliding is directly converted into the radial translation of the clamping bracket 23 and the clamping member 2. The slider 24 slides along the slide rail 12 (first direction) to ensure that the clamping member 2 can only move radially along the mounting hole 11. The slide rail 12 limits the movement direction of the clamping member 2, so that it can accurately approach or move away from the center of the mounting hole 11.

[0123] When the chuck 5 rotates in a certain direction, the sliding wheel 62 gradually moves inward along the linkage hole 51, driving the clamping part 2 to slide along the slide rail 12 toward the center of the mounting hole 11 through the slider 24. Finally, the flexible conductive belt on the clamping part 2 fits tightly against the surface of the plating rod 3 to form a firm electrical connection. The flexible conductive belt is deformed, increasing the contact area and improving the conductivity. On the contrary, when the chuck 5 rotates in the opposite direction, the sliding wheel 62 gradually moves outward along the linkage hole 51, causing the clamping part 2 to move away from the plating rod 3 along the slide rail 12 through the slider 24 and enter a loosened state, making it easier to put in or take out the plating rod 3. At this time, the flexible conductive belt returns to its original state, ready for the next use.

[0124] Among them, the sliding fit of the first limiting wheel 72 in the limiting hole 52 reduces the axial shaking of the chuck 5 and maintains the stability of the chuck 5. At least one group of second limiting members 8 is provided on the fixing seat 1, and each group includes two second limiting members 8, which are respectively arranged on opposite sides of the chuck 5 and are slidably connected to the outer peripheral surface of the chuck 5. The second limiting member 8 includes a second limiting rod 81 and a rotatable second limiting wheel 82 on the top, and a limiting groove 83 is formed inside the second limiting wheel 82. The outer periphery of the chuck 5 slides in the limiting groove 83, ensuring the axial and radial stability of the chuck 5 during rotation.

[0125] The conductive bus 91 is located on the side of the fixing seat 1 opposite to the chuck 5, and serves as a centralized conductive component for collecting currents from each clamping member 2. The conductive member 21 (flexible conductive belt) on each clamping member 2 is electrically connected to the conductive bus 91 through another section of flexible conductive belt. In this way, the current can be transferred from the plating rod 3 to the conductive member 21 on the clamping member 2 through the flexible conductive belt, and then transmitted to the conductive bus 91 through another section of flexible conductive belt, and finally output to the external power supply or circuit by the conductive bus 91.

[0126] It should be particularly pointed out that all clamps 2 are affected by the same force, and because they all follow the same slide rail 12 path, all clamps 2 can be opened and closed synchronously, ensuring that the plating rod 3 always maintains a uniform force state during the entire electroplating process.

[0127] In summary, through the above detailed working process, the conductive fixing mechanism of the present invention realizes high-precision and stable clamping and releasing of the plating rod 3, ensuring good conductive performance and coating protection. This method not only improves the quality and efficiency of electroplating, but also simplifies maintenance and overhaul work.

[0128] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
