Description

Technical Field

[0001] This utility model relates to the technical field of metal surface treatment equipment, and in particular to an anti-oxidation metal surface electroplating positioning device. Background Technology

[0002] Metal electroplating, as a mature surface treatment process, is widely used in industrial production. Its purpose is to improve the corrosion resistance, wear resistance, and aesthetics of workpieces. The quality of electroplating directly depends on whether the coating is uniform and dense. During the electroplating process, to ensure the quality of the coating, the workpiece to be electroplated must be stably immersed in the electroplating solution. Currently, many electroplating operations rely on simple hangers or clamps to fix the workpiece. However, these devices are often simple in structure and cannot guarantee the absolute stability of the workpiece during the electroplating process. Especially when multiple workpieces need to be processed in batches, the opening and closing actions of the clamps on both sides are difficult to synchronize, which can easily cause the workpiece to be misaligned. This results in inconsistent distances between the various surfaces of the workpiece and the anode plate, leading to uneven current density distribution and ultimately forming a coating of varying thickness.

[0003] More importantly, electroplating is a dynamic electrochemical reaction process. Metal ions near the workpiece surface are continuously consumed. If the electroplating liquid is in a static state, the liquid around the workpiece will form an ion-depleted zone due to ion depletion. This local concentration difference is the main reason for scorching, roughness, and even pinhole defects in the coating, which seriously affects the oxidation resistance of the coating. Although some existing electroplating tanks have taken into account stirring, their clamping and positioning functions are often separate from the stirring function, resulting in complex structures or poor performance.

[0004] Therefore, this utility model proposes an anti-oxidation metal surface electroplating positioning device to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems of unstable positioning, asynchronous opening and closing, and uneven stirring of plating solution in the existing anti-oxidation metal surface electroplating positioning device, which easily leads to plating defects, this utility model aims to provide an anti-oxidation metal surface electroplating positioning device with an improved structure that can effectively solve the above problems.

[0006] This utility model provides an anti-oxidation metal surface electroplating positioning device, including: an electroplating tank, and two clamping plates symmetrically arranged in the electroplating tank; as well as a cylinder, a rotating frame three, a rotating frame one, a rotating frame two, and a stirring mechanism.

[0007] The cylinder's output end is movably connected to a clamping plate, which is rotatably connected to one end of a rotating frame three via a pin. The other end of the rotating frame three is rotatably connected to a rotating frame one, which is then rotatably connected to one end of a rotating frame two. The other end of the rotating frame two is rotatably connected to another clamping plate, thus forming a complete linkage clamping system.

[0008] Furthermore, the stirring mechanism is fixedly connected to the inner wall of the electroplating tank. The stirring mechanism includes a crank handle extending out of the electroplating tank, a helical gear three coaxially connected to the crank handle, a turbine one and a turbine two, and the internal turbines are driven by the crank handle to stir.

[0009] Preferably, the stirring mechanism also includes a rotating rod, one end of which meshes with a helical gear three for transmission, and the other end is fixedly connected to a turbine two, realizing direct power transmission.

[0010] Preferably, the stirring mechanism further includes a helical gear one, a helical gear two, and a rotating sleeve. The helical gear one meshes with the helical gear three, and the helical gear one meshes with the helical gear two. The helical gear two drives the rotating sleeve to rotate, while the turbine one is fixedly connected to the outer peripheral wall of the rotating sleeve, forming another independent power transmission path.

[0011] Preferably, the mixing mechanism also includes a fixed pile, and the rotating sleeve is rotatably fitted onto the fixed pile, providing stable axial support for the rotation of the turbine and enhancing the smoothness of operation.

[0012] Preferably, the device also includes a mounting platform, which is fixed on the electroplating tank. The helical gear is rotatably mounted on the mounting platform through a bearing, ensuring the high efficiency and reliability of the gear transmission.

[0013] Preferably, the device further includes a fixed block, on which the middle part of the rotating frame is rotatably mounted, providing a fulcrum for the linkage mechanism.

[0014] Preferably, the device also includes a mounting base, which is fixed to the outer wall of the electroplating tank. The cylinder and the fixing block are both fixedly mounted on the mounting base, integrating the main components of the clamping system for easy installation and maintenance.

[0015] Preferably, the device further includes at least one limiting rod, the two ends of which are fixedly connected to the mounting base and slide through the clamping plate to precisely guide the reciprocating motion of the clamping plate and prevent it from deflecting.

[0016] Preferably, the device further includes a support platform, which is horizontally positioned below the two clamping plates to stably support the metal workpiece to be electroplated.

[0017] This utility model has the following beneficial effects: 1. This utility model, by setting up a clamping mechanism driven by a single cylinder and linked by multiple rotating frames, transforms the linear motion of the cylinder into the synchronous opening and closing motion of two clamping plates, solving the problem of unstable workpiece clamping or asynchronous operation on both sides leading to inaccurate positioning in the prior art, and achieving the technical effect of stable, symmetrical and accurate positioning of metal workpieces.

[0018] 2. This utility model solves the problem of plating defects caused by the plating solution remaining stationary and large differences in local ion concentration in the prior art by setting a stirring mechanism on the inner wall of the electroplating tank. This mechanism is driven by an external crank and controls the synchronous rotation of two turbines through a gear system and a transmission rod system. It achieves the technical effect of uniformly mixing the components of the electroplating solution and effectively improving the quality and uniformity of the plating layer.

[0019] 3. This utility model integrates synchronous clamping and positioning functions with efficient stirring functions into one. The structure is compact and ingenious, and the operation is convenient. Through synergistic effect, it effectively prevents defects such as oxidation and uneven thickness of the plating layer caused by inaccurate positioning or uneven plating solution, and comprehensively improves the overall process level of metal surface electroplating.

[0024] Please refer to Figure 1 , Figure 3 and Figure 4 The stirring mechanism 2 includes a rotating rod 204, one end of which meshes with a helical gear 209, and the other end of which is fixedly connected to a turbine 205. The stirring mechanism 2 also includes a helical gear 207, which meshes with the helical gear 209, a helical gear 208, which meshes with the helical gear 207, and a rotating sleeve 202, which is driven to rotate by the helical gear 208. The turbine 203 is fixedly connected to the outer peripheral wall of the rotating sleeve 202. When the handle 210 is rotated, the rotating rod 204 and the helical gear 207 are driven simultaneously by the helical gear 209, so as to realize the synchronous rotation of the turbine 203 and the turbine 205, thereby fully stirring the electroplating solution and avoiding local concentration differences in the plating solution.

[0025] To ensure the stable operation of the mixing mechanism 2, the device also includes a fixed pile 201, on which the rotating sleeve 202 is rotatably mounted to provide stable axial support for the rotation of the turbine 203. At the same time, the device also includes a mounting platform 206, which is fixed to the electroplating cylinder 1. The helical gear 207 is rotatably mounted on the mounting platform 206 through a bearing to ensure smooth and reliable gear transmission.

[0026] As a preferred embodiment, to provide a stable mounting reference for the clamping linkage mechanism, please refer to... Figure 1 and Figure 2 The device also includes a mounting base 3, which is fixed to the outer wall of the electroplating tank 1, and the cylinder 4 is fixedly mounted on the mounting base 3. In addition, the device also includes a fixing block 7, which is also fixedly mounted on the mounting base 3, and the middle part of the rotating frame 8 is rotatably mounted on the fixing block 7, thereby integrating the entire clamping drive and linkage mechanism together.

[0027] As a further preferred embodiment, to ensure the smoothness and accuracy of the movement of the clamping plate 5, please refer to... Figure 2 The device also includes at least one limiting rod 6. The two ends of the limiting rod 6 are fixedly connected to the mounting base 3 and slide through the clamping plate 5.

[0028] As another preferred embodiment, for convenient support of the metal workpiece to be electroplated, please refer to...

[0029] As a preferred configuration for the stirring mechanism 2, in order to improve the operational stability and transmission reliability of the stirring system, please refer to... Figure 3 and Figure 4 The stirring mechanism 2 also includes a fixed pile 201, and a rotating sleeve 202 is rotatably mounted on the fixed pile 201 to provide a stable central shaft for the rotation of the turbine 203. In addition, the device also includes a mounting platform 206, which is fixed on the electroplating tank 1. The helical gear 207 is rotatably mounted on the mounting platform 206 through a bearing to ensure the smoothness and efficiency of the gear transmission process.

[0030] Working principle: When clamping a workpiece, cylinder 4 is activated. The output end of cylinder 4 drives the side clamping plate 5 connected to it to move. The movement of clamping plate 5 causes the rotating frame 3 10 connected to it to rotate. The rotational force of rotating frame 3 10 is transmitted to rotating frame 1 8, causing rotating frame 1 8 to rotate around its rotation point on fixed block 7. Rotating frame 1 8 then transmits the motion to rotating frame 2 9, which finally drives the other side clamping plate 5 to make synchronous opposite or opposite movements, thereby realizing the synchronous and stable clamping or loosening of the metal workpiece placed on the support table 11. Throughout the process, the limiting rod 6 guides the linear movement of clamping plate 5.

[0031] When the electroplating solution needs to be stirred, the crank handle 210 is manually turned. The crank handle 210 drives the helical gear 209, which is coaxially connected to it, to rotate. The rotation of the helical gear 209 transmits power to two paths simultaneously. First, the helical gear 209 directly drives the rotating rod 204, which meshes with it, to rotate, and in turn drives the turbine 205, which is fixed at the end of the rotating rod 204, to rotate. Second, the helical gear 209 simultaneously drives the helical gear 207, which meshes with it, to rotate. The helical gear 207 then drives the helical gear 208, which drives the rotating sleeve 202, which is sleeved on the fixed pile 201, to rotate, and finally causes the turbine 203, which is fixed on the rotating sleeve 202, to rotate. Through the transmission design, the synchronous rotation of the turbine 203 and the turbine 205 is achieved, which effectively stirs the electroplating solution in the electroplating tank 1 and ensures the uniformity of the electroplating solution composition.
