Description

Technical Field

[0001] This utility model relates to the field of electroplating equipment, and in particular to an eccentric roller for electroplating. Background Technology

[0002] Electroplating rollers are primarily used in electroplating processes to achieve uniform and efficient electroplating of workpiece surfaces through their unique design. These rollers rotate within the electroplating tank, causing the workpiece to tumble and move continuously inside, ensuring that the electroplating solution evenly covers every corner of the workpiece. Using rollers to process parts can also improve electroplating efficiency, reduce electroplating time and costs, and are widely used in the electroplating of various metal workpieces.

[0003] A novel eccentric roller, as described in Chinese patent document CN201921542907.5, includes a roller body and a cover plate. The roller body has a placement door at its upper end, and cover plates are located on both sides. A transition structure, which is the cylinder wall of the roller body, is provided at the contact point between the roller body and the cover plate. A connecting shaft is located at the lower end of one side of one set of cover plates, and a connector is located at the other end of the connecting shaft. A drive shaft is fixedly installed at the upper end of the other side of the connector. This invention effectively reduces the contact area between the parts to be plated and the cover plate through multiple sets of protrusions arranged on the cover plate. The transition structure at the contact point between the roller body and the cover plate, which is the cylinder wall of the roller body, ensures that the angle between the inner wall of the roller body and the cover plate is obtuse after assembly, preventing parts from getting stuck and resulting in high-quality electroplating. The roller body is easily and efficiently connected to the slots on the cover plate, resulting in low manufacturing costs.

[0004] However, the above-mentioned patent has certain defects in use. When processing, if a large number of workpieces are put in, the drum will stack during the movement of the drum. The dispersion of the plating solution in the drum is limited, resulting in uneven electroplating on the surface of the workpieces and affecting product quality.

[0005] To address this issue, an eccentric roller for electroplating is proposed. Utility Model Content

[0006] To overcome the shortcomings of existing technologies where multiple workpieces may stack when the rollers move, this utility model provides an eccentric roller for electroplating.

[0007] This utility model is achieved using the following technical solution:

[0008] An eccentric roller for electroplating includes a connecting frame and an eccentric roller. The eccentric roller has connecting shafts at both ends that are connected to the connecting frame. A first gear is provided on one end of the connecting shaft, and a drive motor is provided on one side. The output end of the drive motor has a rotating shaft, and one end of the rotating shaft has a second gear that meshes with the first gear. An isolation plate is built into the middle layer of the eccentric roller, which divides the interior of the eccentric roller into a first chamber and a second chamber. An independently operable stirring device is installed in both the first chamber and the second chamber.

[0009] As a preferred embodiment of this utility model, the stirring device includes: a movable rod, a movable bushing, and a stirring spoon. Multiple stirring spoons are evenly distributed circumferentially on the periphery of the movable rod, and the movable bushing is movably connected to both ends of the movable rod. The movable bushing is fixedly installed on the inner wall of the eccentric drum.

[0010] As a preferred embodiment of this utility model, the top and bottom of the eccentric roller are provided with fixing plates, and multiple installation ports are provided on the fixing plates. The upper ends of the first chamber and the second chamber are provided with inlets along the fixing plates and penetrating the eccentric roller. The inlets are provided with detachable sealing caps, and the top of the sealing caps is provided with handles.

[0011] As a preferred embodiment of this utility model, the sealing cover is movably connected with a locking rod that matches the number of installation ports. The locking rod is provided with an adjustment knob, and the two ends of the locking rod are provided with locking hooks that match the installation ports.

[0012] As a preferred embodiment of this utility model, the eccentric roller and the sealing cover are provided with multiple injection holes.

[0013] As a preferred embodiment of this utility model, the top of the connecting frame is symmetrically provided with upper connections.

[0014] As a preferred embodiment of this utility model, the isolation plate has multiple flow holes that connect the first chamber and the second chamber, and each flow hole is provided with a mesh screen.

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] 1. The eccentric roller is divided into a first chamber and a second chamber by a partition plate. The partition plate effectively separates the workpieces. The flow holes and the mesh screen ensure that the plating solution is evenly distributed in the first and second chambers while ensuring that the workpieces in the corresponding chambers do not interfere with each other.

[0017] 2. The drive motor drives the rotating shaft to rotate the first gear, which in turn drives the eccentric drum to rotate. The stirring device works synchronously to ensure that the plating solution flows evenly in the two chambers. While the eccentric drum rotates, it avoids the stacking of workpieces, effectively improving the uniformity of electroplating on the workpiece surface, thereby improving product quality.

The two chambers are independent of each other. An independently working stirring device 7 is provided in both the first chamber 4 and the second chamber 5 to prevent the workpieces from stacking while the eccentric roller 2 rotates.

[0028] Specifically, the stirring device 7 includes: a movable rod 71, a movable bushing 72, and a stirring spoon 73. Multiple stirring spoons 73 are evenly distributed circumferentially on the periphery of the movable rod 71, and the movable bushing 72 is movably connected to both ends of the movable rod 71.

The two ends of the locking rods 62 are provided with locking hooks 63, which are tightly engaged with the edges of the mounting openings 27. The locking rods 62 are provided with knobs 65 for adjusting the locking rods 62. When it is necessary to open the sealing cover 6, the operator rotates the knobs 65 to unscrew the locking hooks 63 at both ends of the locking rods 62 from the mounting openings 27, and then opens the sealing cover 6 by gripping the handle 64.

[0034] Specifically, the eccentric roller 2 and the sealing cover 6 are provided with multiple injection holes 8.

[0035] In this embodiment, the eccentric roller 2 and the sealing cover 6 are provided with a plurality of injection holes 8, which are connected to the first chamber 4 and the second chamber 5.
