Description

Technical Field

[0001] This utility model relates to the field of electroplating technology, specifically to an electroplating tank for electroplating. Background Technology

[0002] Currently, various devices for preventing electroplating solution splashing have emerged in the industry. Among them, utility model patent CN223033493U discloses an electroplating tank for electroplating processing. This device divides the tank into several sub-tanks by setting partition walls inside the tank, and connects anti-splash plates above the partition walls. The anti-splash plates are fixed by inserting limiting strips into the limiting grooves of the mounting strips, while fixing components prevent the anti-splash plates from accidentally sliding out. In practical applications, this device can effectively block the splashing solution between adjacent sub-tanks through the anti-splash plates. When electroplating large metal parts, splashed electrolyte can be blocked by the anti-splash plates, which to some extent solves the problem of cross-tank contamination of electroplating solution and provides a certain guarantee for improving the stability of electroplating operations.

[0003] However, the limitations of this device become increasingly apparent in barrel plating processes. In barrel plating, workpieces are typically placed in a barrel plating basket for electroplating. After plating, the basket needs to be transferred from the current plating tank to the next to complete multiple processing steps. Existing barrel plating equipment has limited lifting height due to factors such as equipment structure, load-bearing capacity, and operating costs, preventing significant lifting. The splash guard in the aforementioned patented device is fixed above the partition wall, positioned precisely on the conventional movement path of the barrel plating basket. To apply this device in barrel plating, to avoid collisions and interference between the splash guard and the basket, a specially designed barrel plating basket capable of rising significantly must be manufactured, increasing the lifting stroke to bypass the splash guard. This modification not only significantly increases equipment manufacturing and maintenance costs but may also lead to decreased operational stability due to excessive basket lifting height, increasing the risk of workpiece falling and equipment malfunction. Furthermore, it is incompatible with the standard barrel plating baskets of most existing barrel plating equipment, severely restricting the device's versatility and practicality in barrel plating processes, and failing to meet the industry's demand for efficient and low-cost electroplating operations.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 This utility model provides a technical solution: An electroplating bath for electroplating processing, comprising: Multiple sets of electroplating tanks 1 are set on the ground, and electroplating solution is placed inside the electroplating tanks 1. The multiple sets of electroplating tanks 1 are distributed at equal intervals along a straight line. Multiple sets of anti-splash baffles 2 are provided on the side of the electroplating tank 1, and the anti-splash baffles 2 separate two adjacent sets of electroplating tanks 1. The baffle adjustment device 3 includes multiple sets of extension arms 4 and a rotating shaft 5. The rotating shaft 5 is located on one side of the multiple sets of electroplating tanks 1 and is parallel to the multiple sets of electroplating tanks 1. One end of the extension arm 4 is fixedly connected to the anti-splash baffle 2, and the other end of the extension arm 4 is fixedly connected to the rotating shaft 5. A drive mechanism is provided on one side of the rotating shaft 5, and the multiple sets of anti-splash baffles 2 can rotate around the axis of the rotating shaft 5. By using the baffle adjustment device 3 to rotate the multiple sets of anti-splash baffles 2, the baffles can switch between a blocking and splash-avoiding posture. During electroplating operations, the multiple sets of anti-splash baffles 2 are positioned above the multiple sets of electroplating tanks 1 to prevent electroplating liquid from splashing into adjacent electroplating tanks. When loading and unloading materials after electroplating, the multiple sets of anti-splash baffles 2 can be rotated and moved away to avoid affecting the loading and unloading of materials. Especially in barrel plating processes, the barrel plating basket usually has a limited height. By removing multiple sets of anti-splash baffles 2, existing barrel plating devices can be used, avoiding the anti-splash baffles 2 from blocking the movement path of the barrel plating basket. This method is convenient to use, highly practical, and suitable for rack plating and barrel plating processes.

[0018] Furthermore, a mating spacer 6 is provided on the side of the electroplating tank 1, and a silicone pad 7 that mates with the mating spacer 6 is fixedly installed on the anti-splash baffle 2. The anti-splash baffle 2 is placed on the mating spacer 6, and the side of the silicone pad 7 facing away from the anti-splash baffle 2 abuts against the top surface of the mating spacer 6. In the anti-splash position, the flexible deformation of the silicone pad 7 can fill the gap between the anti-splash baffle 2 and the mating spacer 6, preventing the electroplating solution from penetrating through, thus providing good protection. It is recommended to use adhesive to fix the silicone pad 7 to the anti-splash baffle 2.

[0019] Furthermore, support blocks 8 are provided on both ends of the multiple electroplating tanks 1, and a bearing seat 9 is provided on one side of the support block 8. The rotating shaft 5 is rotatably connected to the support block 8 through the bearing seat 9.

[0020] Furthermore, a cavity is provided below the partition 6, and the splash guard 2 can be rotated and stored in the cavity.

[0021] Furthermore, a flexible shock-absorbing pad 10 corresponding to the extension arm 4 is provided at the bottom of the spacer 6. The flexible shock-absorbing pad 10 is recommended to be made of rubber, which can prevent the extension arm 4 from rigidly contacting the spacer 6 and can greatly improve the service life of the device.

[0022] Furthermore, the drive mechanism includes a large gear 11, a small gear 12, and a servo motor 13. The large gear 11 is coaxially and fixedly connected to the rotating shaft 5. The small gear 12 is located on one side of the large gear 11 and meshes with it. The servo motor 13 is fixedly mounted on the support block 8, and its output end is coaxially and fixedly connected to the small gear 12. The cooperation between the large gear 11 and the small gear 12 can slow down the rotation speed of the rotating shaft 5 and improve accuracy. The servo motor 13 must be a servo motor capable of precisely controlling the rotation angle. Its controller, as a motor accessory, is provided by the motor supplier. It is recommended to install a housing on the outside of the large gear 11, the small gear 12, and the servo motor 13 to prevent contact damage and the entry of debris into the gear gaps.

[0023] Furthermore, a counterweight 14 is provided at the end of the rotating shaft 5 opposite to the drive mechanism. The counterweight 14 is used to balance the center of gravity, so that the center of gravity of the entire rotating shaft 5 and the combination of multiple anti-splash baffles 2 is located as close as possible to the axis of the rotating shaft 5, which can avoid vibration caused by rotation and improve service life.

[0024] Furthermore, the end of the extension arm 4 is provided with two sets of fixing lugs 15. The fixing lugs 15 and the splash guard 2 have through-hole fixing holes, in which fastening bolts 16 are installed. Each set of fixing lugs 15 contains a threaded sleeve 17 that mates with the fastening bolts 16. The splash guard 2 can be detached from the extension arm 4. After prolonged use, a large amount of plating solution accumulates on the surface of the splash guard 2, forming a layer of dirt. The splash guard 2 can be removed for cleaning and maintenance.

The top surface can support the anti-splash baffle 2 with silicone pad 7. Silicone pad 7: A flexible pad fixed on the anti-splash baffle 2. The side facing away from the anti-splash baffle 2 abuts against the top surface of the mating spacer 6. It can fill the gap between the two through flexible deformation to prevent electroplating solution from penetrating. Support block 8: A block-shaped support structure located on both sides of the first and last sides of multiple electroplating tanks 1. One side is equipped with a bearing seat 9 and a servo motor 13 is fixed on it, providing mounting support for the rotating shaft 5 and the servo motor 13. Shaft seat 9: A bushing structure located on one side of the support block 8, which sleeves the rotating shaft 5 and makes it rotatably connected to the support block 8, and assists the rotating shaft 5 to rotate stably; Impact-resistant flexible pad 10: It is recommended to use a rubber material and place the pad at the bottom of the mating spacer 6, corresponding to the position of the extension arm 4, so as to avoid rigid contact between the extension arm 4 and the mating spacer 6 and reduce component wear. Large gear 11: A gear structure that is fixedly connected to the rotating shaft 5 on the same axis. It meshes with the small gear 12 on one side and can work with the small gear 12 to slow down the rotation speed of the rotating shaft 5 and improve control accuracy.

Both the extension arm 4 and the splash guard 2 have through-type fixing holes. Fastening bolts 16 and threaded sleeves 17 can be installed in the holes to connect the extension arm 4 and the splash guard 2. Fastening bolt 16: A bolt structure that passes through the fixing holes of the fixing clip 15 and the splash guard 2, and cooperates with the threaded sleeve 17 to realize the detachable fixing of the extension arm 4 and the splash guard 2; Screw sleeve 17: A sleeve structure located within a set of fixed clamps 15, which cooperates with fastening bolts 16 to assist the fastening bolts 16 in fixing the fixed clamps 15 to the splash guard 2.

[0026] Working Principle: During the electroplating process, multiple anti-splash baffles 2 are in a shielding and anti-splash posture. A servo motor 13 drives a pinion 12 to rotate, which, through meshing with a large gear 11, drives the rotating shaft 5 to rotate. This causes the extension arm 4 to push the anti-splash baffle 2 upwards around the axis of the rotating shaft 5 until the bottom of the anti-splash baffle 2 is placed on the mating spacer 6. The silicone pad 7 on the anti-splash baffle 2 is in close contact with the top surface of the mating spacer 6. The flexible deformation of the silicone fills the gap between them, forming a sealed barrier structure. This effectively prevents the electroplating solution in the electroplating tank 1 from splashing into adjacent electroplating tanks 1 during workpiece agitation, ensuring the stability of the electroplating solution composition in each electroplating tank 1. The rotating shaft 5 is mounted on support blocks 8 via bearings 9. The support blocks 8 at both ends provide stable support for the rotating shaft 5. Simultaneously, a counterweight 14 at the end of the rotating shaft 5 away from the drive mechanism balances the overall center of gravity, preventing vibration during rotation and ensuring the positioning accuracy of the anti-splash baffle 2.

[0027] When the electroplating operation is completed and the loading / unloading stage begins, the baffle adjustment device 3 drives the anti-splash baffle 2 to switch to an avoidance posture. The servo motor 13 rotates in reverse, driving the rotating shaft 5 to rotate in the opposite direction through gear transmission. The extension arm 4 then drives the anti-splash baffle 2 to rotate downwards until the anti-splash baffle 2 is completely housed in the cavity below the mating spacer 6. During this process, the extension arm 4 contacts the impact-resistant flexible pad 10 at the bottom of the mating spacer 6. The rubber flexible pad can buffer the impact force of the collision and avoid wear of the parts caused by rigid contact. After the anti-splash baffle 2 is removed, the channel between adjacent electroplating tanks 1 is completely open, without obstructing the movement path of the barrel plating basket. It is compatible with the conventional lifting height of existing barrel plating devices, and the transfer of workpieces between electroplating tanks 1 can be completed without the need for specially heightened barrel plating baskets, while also not affecting the loading / unloading operation of the rack plating process.

[0028] The extension arm 4 is connected to the splash guard 2 via the fixed clamp 15. The fastening bolt 16 passes through the fixing hole and cooperates with the screw sleeve 17 to achieve detachable fixing, which facilitates disassembly and cleaning after dirt adheres to the surface of the splash guard 2. The reduction gear 11 and the small gear 12 improve the angle control accuracy of the rotating shaft 5, ensuring that the splash guard 2 can accurately stop at the working position.

[0029] This device can reliably block electroplating solution splashes and flexibly avoid loading and unloading paths, balancing protective performance with ease of operation. It is suitable for various electroplating processes such as barrel plating and rack plating.
