Description

Technical Field

[0001] This utility model relates to the field of electroplating technology, specifically to an anti-clogging spot plating wheel. Background Technology

[0002] The spot plating wheel is the core component in the spot plating process. It selectively electroplats to achieve coating coverage on localized areas of a material strip and is widely used in precision manufacturing fields such as electronic components and connectors. Its working process can be divided into four key stages: plating solution circulation, material transfer, localized electroplating, and plating solution recovery. The electroplating solution is transported from the storage tank to the inside of the spot plating wheel through a pump, flowing through the flow channel formed by the wheel frame and the mixing fan blades. The mixing fan blades are passively rotated under the drive of the plating solution flow or the wheel frame rotation, enhancing the plating solution mixing effect and avoiding uneven coating caused by concentration gradients. The material strip to be electroplated enters the spot plating wheel system through an unwinding device, and is adjusted to a suitable tension by a tension wheel to avoid wrinkles or breakage. The material strip is then bonded to the surface of the spot plating wheel through an RTV mask. The openings on the mask are precisely aligned with the spot plating hole group of the spot plating wheel, exposing only the area to be plated. The plating solution is sprayed out from the spot plating holes of the spot plating wheel, directly acting on the exposed area of ​​the material strip.

[0003] Because spot plating wheels can selectively electroplate functional areas with a small plating area, they can effectively save precious metals such as gold and silver. However, existing spot plating wheels have the following problems: the spot plating holes are prone to clogging. The spot plating slots are usually set to be small, but during use, the spot plating solution tends to adhere to the edge of the spot plating hole and crystallize inside the spot plating hole, causing the spot plating hole to become clogged, the solution cannot be sprayed out or the spraying force is insufficient, which in turn causes abnormal batch gold plating and reduced output. Therefore, a device is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an anti-clogging spot plating wheel to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-clogging spot plating wheel, comprising a limiting wheel rim, spot plating holes, an annular wheel body, a drive connecting shaft, and a dredging body. The limiting wheel rim is fixedly connected to both sides of the annular wheel body, the spot plating holes are evenly opened on the annular wheel body, the drive connecting shaft is fixedly disposed in the middle of the annular wheel body and the drive connecting shaft, and the dredging body is disposed above the annular wheel body.

[0006] Preferably, the unblocking body includes a fixed mounting plate, an electric push rod, a mounting limit frame, a cleaning end, and a rotating cleaning wheel. The fixed mounting plate is fixedly connected to the upper end of the electric push rod. The bottom end of the electric push rod is fixedly connected to the middle of the upper end of the mounting limit frame by bolts. The rotating cleaning wheel is rotatably engaged inside the bottom end of the mounting limit frame. The cleaning end is evenly fixedly installed on the rotating cleaning wheel.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] During use, this invention utilizes a dredging body to periodically clean the plating holes on the annular wheel using a rotating cleaning wheel and a cleaning end. The operating mode of the dredging body can be adjusted and controlled based on factors such as the rotational speed of the annular wheel, the size of the plating holes, and the ease of insertion of the descending cleaning end. This ensures that the rotating cleaning wheel is inserted into the plating holes during installation and that the rotational speed of the wheel is controlled, guaranteeing that the cleaning end is always inserted into the holes for continuous, real-time cleaning. Therefore, the plating holes will not become clogged during prolonged use, ensuring continuous and stable electroplating. Attached Figure Description

[0017] 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.

[0018] Please see Figure 1 , Figure 2 and Figure 3 The present invention provides an embodiment of an anti-clogging spot plating wheel, comprising a limiting wheel rim 1, spot plating holes 2, an annular wheel body 3, a drive connecting shaft 4, and a clearing body 5. The limiting wheel rim 1 is fixedly connected to both sides of the annular wheel body 3, the spot plating holes 2 are evenly opened on the annular wheel body 3, the drive connecting shaft 4 is fixedly arranged in the middle of the annular wheel body 3 and the drive connecting shaft 4, and the clearing body 5 is arranged above the annular wheel body 3.

[0019] The main body 5 includes a fixed mounting plate 6, an electric push rod 7, a mounting limit frame 8, a cleaning end 10, and a rotating cleaning wheel 11. The fixed mounting plate 6 is fixedly connected to the upper end of the electric push rod 7. The bottom end of the electric push rod 7 is fixedly connected to the middle of the upper end of the mounting limit frame 8 by bolts. The rotating cleaning wheel 11 is rotatably engaged inside the bottom end of the mounting limit frame 8. The cleaning end 10 is evenly fixedly installed on the rotating cleaning wheel 11.

[0020] A motor 9 is fixedly installed on the outer side of the bottom end of the mounting limit frame 8, and the drive end of the motor 9 is fixedly connected to the middle of the rotating cleaning wheel 11.

[0021] The rotating cleaning wheel 11 is located directly above the annular wheel body 3, and the cleaning end 10 is located directly above the spot plating hole 2, so that the cleaning end 10 can be stably and accurately inserted into the interior of the spot plating hole 2.

[0022] The cleaning end 10 is adapted to the spot plating hole 2. The end of the cleaning end 10 is tapered and can be fully inserted into the spot plating hole 2 to complete the unblocking and cleaning.

[0023] Working principle: During use, the annular wheel 3 is connected to external equipment via the drive connecting shaft 4 and rotates. After a specified time of continuous electroplating, the electric push rod 7 and the motor 9 are activated. The electric push rod 7 drives the mounting limit frame 8 and the rotating cleaning wheel 11 to move downwards. The motor 9 drives the rotating cleaning wheel 11 to rotate at a constant speed. This allows the evenly distributed cleaning tips 10 on the rotating cleaning wheel 11 to insert into the plating holes 2 on the annular wheel 3 as it slowly moves downwards. At this time, the evenly distributed cleaning tips 10 insert into each plating hole 2 during rotation, cleaning the inside of the plating holes 2. Furthermore, the end of the cleaning head 10 is tapered, which ensures that it can be fully inserted into the plating hole 2 to prevent internal blockage during continuous use. In order to prevent the cleaning head 10 from being difficult to accurately insert into the plating hole 2 due to continuous lifting and lowering, the position of the rotating cleaning wheel 11 and the cleaning head 10 in the unblocking body 5 can be adjusted during the overall installation of the unblocking body 5 so that the cleaning head 10 is always inserted into the plating hole 2 without separation. Then, during the rotation of the annular wheel 3, the cleaning head 10 always cleans the inside of the plating hole 2 to prevent internal blockage.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
