Abstract
Description
Technical Field
[0001] This utility model relates to the field of electroplating equipment technology, and in particular to a blind hole stirring fixture and electrode column production line. Background Technology
[0002] In related technologies, some electroplated products are usually equipped with blind holes. During the electroplating process (chemical degreasing, electrolytic degreasing, electroless nickel plating, etc.), the chemical liquids of different process steps are prone to deposit deep in the blind holes, resulting in poor electroplating effect of the electroplated products. Utility Model Content
[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a blind hole stirring fixture, which uses a stirring rod to stir the chemical solution inside the blind hole, thereby improving the degreasing, electroplating, and washing effects.
[0004] On one hand, this utility model embodiment provides a blind hole stirring fixture, including:
[0005] Soft dragon skeleton;
[0006] Several sets of fixing hooks, each set including a flow-guiding and stirring fixing hook and a product fixing hook, are arranged sequentially along the extension direction of the soft keel frame.
[0007] The flow-guiding stirring fixing hook includes a connecting rod and a stirring rod. The first end of the connecting rod is connected to the soft keel frame, and the second end of the connecting rod extends toward the product fixing hook. The stirring rod can be inserted into the blind hole of the electrode post.
[0008] The first end of the product fixing hook is connected to the soft dragon frame, and the second end of the product fixing hook can be movably connected to the electrode post.
[0009] This utility model embodiment has at least the following beneficial effects: By setting a stirring rod inserted into the blind hole of the electrode post and stirring, the liquid in the blind hole is convected. During the degreasing process, the oil in the blind hole is stirred and flows out of the hole, ensuring clean degreasing and preventing peeling after electroplating due to incomplete degreasing. During the nickel plating process, the convection effect generated by stirring allows new nickel plating solution to flow into the blind hole, while the old nickel plating solution flows out of the blind hole, ensuring that the blind hole does not trap air and improving the nickel plating effect. Furthermore, when the electrode post is inverted (blind hole facing down), the stirring action of the stirring rod can make the chemical liquid in the blind hole flow out of the blind hole quickly, preventing the chemical liquid from being trapped in the hole and rusting after drying. Moreover, in order to avoid cross-contamination of chemical liquids in different processes, a water washing step is required between processes. During the water washing process, the stirring of the stirring rod improves the cleaning effect of the water flow on the inside of the blind hole.
[0010] According to some embodiments of the present invention, the product fixing hook includes two clamping arms, the first ends of the two clamping arms are connected to the soft keel frame, the second ends of the two clamping arms can move freely and elastically return to their original position, and the product fixing hook includes a limiting state, the limiting state being the state in which the two clamping arms are inserted into the through hole of the electrode post;
[0011] The distance between the second ends of the two clamping arms is greater than a set distance, which is the diameter of the through hole of the electrode post.
[0012] According to some embodiments of the present invention, the clamping arm is provided with an arc-shaped portion, and the openings of the arc-shaped portions of the two clamping arms are arranged opposite to each other; the distance between the starting ends of the two arc-shaped portions is greater than the set distance, and the distance between the ending ends of the two arc-shaped portions is greater than the set distance.
[0013] According to some embodiments of the present invention, the two clamping arms are staggered along the extending direction, and the first ends of the two clamping arms at least partially overlap on the orthographic projection plane along the extending direction.
[0014] According to some embodiments of the present invention, the soft keel frame is provided with a reinforcing part, which protrudes from the surface of the soft keel frame and is arranged around the first end of the clamping arm.
[0015] According to some embodiments of the present invention, the blind hole stirring hanger further includes a handle, which is fixed to the soft auger frame and extends from the soft auger frame in a direction away from the soft auger frame.
[0016] According to some embodiments of the present invention, the blind hole stirring hanger further includes a first hook, which is connected to one end of the soft keel frame near the flow-guiding stirring fixing hook. The first hook, the soft keel frame, the flow-guiding stirring fixing hook, and the product fixing hook are conductive.
[0017] According to some embodiments of the present invention, the blind hole stirring hanger further includes a second hook, and along the extending direction, the second hook and the first hook are respectively disposed at both ends of the soft keel frame.
[0018] According to some embodiments of the present invention, the blind hole stirring hanger further includes an isolation sleeve, which is wrapped around the outer surface of the second hook.
[0019] On the other hand, the electrode column production line according to the second aspect of the present invention includes the blind hole stirring fixture as described above.
[0020] The technical effects of the electrode column production line in this utility model embodiment are the same as those of the blind hole mixing fixture in this application embodiment, and will not be repeated here.

If "first," "second," etc., are used in the description, they are only for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the sequential relationship of the indicated technical features.
[0032] In the description of this utility model, unless otherwise explicitly defined, the terms "setting", "installation", "connection", etc. should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in combination with the specific content of the technical solution.
[0033] Please refer to Figure 1 On one hand, this utility model embodiment provides a blind hole stirring hanger for mounting electrode posts (which can be iron electrode posts, copper electrode posts, nickel electrode posts, etc.) with blind holes. The blind hole stirring hanger includes a flexible frame 100 and several fixing hook groups 200. The fixing hook groups 200 include a flow-guiding stirring fixing hook 210 and a product fixing hook 220. The flow-guiding stirring fixing hook 210 and the product fixing hook 220 are arranged sequentially along the extension direction of the flexible frame 100. The flow-guiding stirring fixing hook 210 includes a connecting rod 211 and a stirring rod 212. The first end of the connecting rod 211 is connected to the flexible frame 100, and the second end of the connecting rod 211 extends toward the product fixing hook 220 with the stirring rod 212. The stirring rod 212 can be inserted into the blind hole of the electrode post. The first end of the product fixing hook 220 is connected to the flexible frame 100, and the second end of the product fixing hook 220 can be movably connected to the electrode post.
[0034] According to the blind hole stirring fixture of this utility model embodiment, the operator hangs the electrode column between the flow-guiding stirring fixing hook 210 and the product fixing hook 220 of the blind hole stirring fixture for limiting and fixing. During the electrode column processing (degreasing, electroplating, etc.), different chemical liquids will spray or soak the electrode column and deposit in the blind hole. The stirring rod 212 of the flow-guiding stirring fixing hook 210 is inserted into the blind hole and stirs the chemical liquid in the blind hole with the shaking of the electrode column on the blind hole stirring fixture, thereby improving the processing effect of the electrode column.
[0035] It should be noted that in the relevant technologies, electrode posts with blind holes need to undergo processes such as degreasing, nickel plating, and water washing during processing. In the degreasing process, the degreasing chemical liquid used to hang the electrode posts in the relevant technologies causes the oil stains after degreasing the blind holes to be deposited at the bottom of the blind holes, resulting in incomplete cleaning. In the nickel plating process, fixing the blind holes downwards can ensure that the nickel plating chemical liquid flows out of the blind holes, but it will cause air to accumulate inside the blind holes and prevent nickel from being deposited.
[0036] According to the blind hole stirring fixture of this utility model embodiment, by setting a stirring rod 212 inserted into the blind hole of the electrode post to stir, the liquid in the blind hole is stirred to achieve a convection effect. During the degreasing process, the oil in the blind hole is stirred and flows out of the hole, ensuring that the oil is thoroughly removed and preventing peeling of the electrode post after electroplating due to incomplete degreasing. During the nickel plating process, the convection effect generated by stirring allows new nickel plating solution to flow into the blind hole, while the old nickel plating solution flows out of the blind hole, ensuring that the blind hole does not trap air and improving the nickel plating effect. Furthermore, when the electrode post is inverted (blind hole facing down), the stirring action of the stirring rod 212 can make the chemical liquid in the blind hole flow out of the blind hole quickly, preventing the chemical liquid from being trapped in the hole and rusting after drying. Moreover, in order to avoid cross-contamination of chemical liquids in different processes, a water washing step is required between processes. During the water washing process, the stirring of the stirring rod 212 improves the cleaning effect of the water flow on the inside of the blind hole.
[0037] In this embodiment, "the second end of the product fixing hook 220 can be movably connected to the electrode post" can be understood as the second end of the product fixing hook 220 being fixed to the electrode post while having a certain range of movement, so that the electrode post can vibrate relative to the product fixing hook 220 to achieve stirring of the liquid in the blind hole by the stirring rod 212.
[0038] In this embodiment, the soft dragon frame 100 is provided with three layers, each layer including fifteen fixing hook groups 200; of course, the specific number of fixing hook groups 200 can be adjusted according to actual needs.
[0039] In some embodiments, combined with Figure 1 and Figure 2 As shown, the product fixing hook 220 includes two clamping arms 221. The first end of the two clamping arms 221 is connected to the soft keel frame 100. The second end of the two clamping arms 221 can move freely and elastically return to its original position. The product fixing hook 220 includes a limiting state, which is the state in which the two clamping arms 221 are inserted into the through hole of the electrode post. The distance between the second ends of the two clamping arms 221 is greater than a set distance, which is the diameter of the through hole of the electrode post.
[0040] In this embodiment, for an electrode post with blind holes and through holes, the through holes are limited and fixed by the clamping arm 221 and the blind holes are limited by the stirring rod 212, so as to realize the limit and movable connection of the entire electrode post on the hanger, and ensure that the stirring rod 212 can achieve the stirring effect when the electrode post shakes.
[0041] In this embodiment, when the operator installs the electrode post, he controls the second ends of the two clamping arms 221 to move together to pass through the through hole, and after passing through the through hole, the electrode post is elastically reset to a limited state. Since the distance between the second ends of the clamping arms 221 is greater than the diameter of the through hole, the electrode post is guaranteed not to detach from the clamping arms 221.
[0042] Of course, in other embodiments, the product fixing hook 220 can also be adapted to the shape of an electrode post without a through hole. For example, the second end of the product fixing hook 220 can be in the form of a claw. The claw wraps around the end of the electrode post without a blind hole. When the electrode post shakes, the claw can contact the outer periphery of the electrode post to limit the electrode post.
[0043] In some embodiments, combined with Figure 2 As shown, the clamping arm 221 has an arc-shaped portion 2211, and the openings of the arc-shaped portions 2211 of the two clamping arms 221 are arranged opposite to each other; the distance between the starting ends of the two arc-shaped portions 2211 is greater than a set distance, and the distance between the ending ends of the two arc-shaped portions 2211 is greater than a set distance.
[0044] In this embodiment, the through hole of the electrode post is sleeved on the arc-shaped part 2211. The distance between the starting end and the ending end of the arc-shaped part 2211 is set to ensure that the through hole cannot be disengaged from the arc-shaped part 2211, thereby realizing the limiting connection of the electrode post. When the arc-shaped part 2211 is engaged with the through hole, it only contacts the opening of the through hole, effectively ensuring the degreasing or nickel plating effect of the inner wall of the through hole.
[0045] In some embodiments, combined with Figure 1 and Figure 2 As shown, along the extension direction (Z direction in the figure), the two clamping arms 221 are staggered, and on the orthographic projection plane along the extension direction, the first ends of the two clamping arms 221 at least partially overlap. This effectively reduces the volume occupied by a single product fixing hook 220 in the radial direction of the soft keel frame 100, increases the number of product fixing hooks 220 that can be installed on the soft keel frame 100, and improves the production efficiency of the electrode posts.
[0046] In some embodiments, combined with Figure 1 and Figure 2 As shown, the soft auger frame 100 is provided with a reinforcing part 110, which protrudes from the surface of the soft auger frame 100 and surrounds the first end of the clamping arm 221. Since the operator needs to move the second end of the clamping arm 221 each time the electrode post is installed, the first end of the clamping arm 221 accumulates fatigue. By providing the reinforcing part 110, the connection strength between the soft auger frame 100 and the clamping arm 221 is strengthened, effectively improving the service life of the blind hole stirring fixture.
[0047] In some embodiments, combined with Figure 1 As shown, the blind hole mixing fixture also includes a handle 300, which is fixed to the flexible keel frame 100 and extends from the flexible keel frame 100 in a direction away from it. The handle 300 facilitates the handling and movement of the blind hole mixing fixture by the operator.
[0048] In some embodiments, combined with Figure 1As shown, the blind hole stirring hanger also includes a first hook 400, which is connected to one end of the soft keel frame 100 near the flow-guiding stirring fixing hook 210, so that the blind hole stirring hanger can be hung on special equipment. The first hook 400, the soft keel frame 100, the flow-guiding stirring fixing hook 210 and the product fixing hook 220 are conductive to ensure the electroplating effect of the electrode column.
[0049] In some embodiments, combined with Figure 1 As shown, the blind hole mixing fixture also includes a second hook 500. Along the extension direction, the second hook 500 and the first hook 400 are respectively located at both ends of the soft keel frame 100.
[0050] In this embodiment, between different processes (degreasing, nickel plating, etc.), the chemical liquid in the blind hole needs to be poured out and cleaned to avoid cross-contamination between chemical liquids from different processes. The second hook 500 ensures that the blind hole stirring fixture can be mounted in a special device to invert the blind hole and allow the chemical liquid to flow out. Furthermore, during the final water blowing process of the electrode post electroplating process, the inversion allows the liquid in the blind hole to flow out, ensuring that the blind hole is dry.
[0051] In some embodiments, the blind hole stirring hanger also includes an insulating sleeve that wraps around the outer surface of the second hook 500. The insulating sleeve effectively isolates the second hook 500 from the external environment, preventing the hook from being directly exposed to chemical liquids and air, thereby reducing oxidation, rust, and other problems, and significantly extending the service life of the hook.
[0052] On the other hand, the electrode column production line according to the second aspect of the present invention includes a blind hole stirring fixture as described in the above embodiment.
[0053] The technical effects of the electrode column production line in this utility model embodiment are the same as those of the blind hole mixing fixture in this application embodiment, and will not be repeated here.
[0054] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
