Description

Technical Field

[0001] This application relates to the field of electroplating auxiliary tools, and in particular to an electroplating rack. Background Technology

[0002] In the electroplating and automation industries, the design of electroplating racks is crucial for improving production efficiency and product quality. With the continuous development of electroplating processes, the performance requirements for electroplating racks are becoming increasingly stringent. A good electroplating rack can not only improve the uniformity and stability of electroplating but also increase production efficiency and reduce production costs. In actual production, electroplating racks need to meet various functional requirements, such as shielding current and efficient hanging of products. The realization of these functions directly affects the quality and efficiency of electroplating production.

[0003] In the past, to achieve the functions of electroplating racks, the industry typically used single-piece electroplating racks. These racks required an external structure to achieve the current shielding function. When hanging products, space needed to be allocated for the hanging process, limiting the number of products that could be hung simultaneously. Furthermore, removing products from the rack after electroplating was inconvenient, requiring careful handling to avoid scratching the products.

[0004] Existing single-piece electroplating racks have significant drawbacks. Firstly, the added structure for current shielding increases operational complexity and cost. Secondly, the limited hanging space restricts the number of products that can be hung simultaneously, reducing production efficiency. Furthermore, removing electroplated products is inconvenient, affecting not only hanging efficiency but also the ease with which products can be scratched, impacting product quality. Utility Model Content

[0005] The purpose of this application is to provide an electroplating hanger.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: an electroplating rack, comprising a lower body and a movable upper cover; the lower body is provided with a hanging position for carrying electroplated products along its own length direction; the movable upper cover is connected to the lower body through a movable connecting structure, and can move relative to the lower body to achieve switching between open and closed states; when in the closed state, the movable upper cover cooperates with the hanging position to fix the electroplated products arranged on the hanging position; when it is necessary to place products to be electroplated or to take out products that have been electroplated, it can be switched to the open state to increase the operating space of the hanging position, thereby increasing the product carrying capacity per unit space under the same rack size, and facilitating the placement and removal of electroplated products.

[0007] By adopting the above technical solution, the openable design of the movable upper cover and lower body significantly increases the operating space of the hanging position when open. Unlike existing single-piece hangers, there is no need to reserve redundant space for hanging actions. This facilitates the rapid hanging of products to be electroplated and the convenient retrieval of products after electroplating, effectively avoiding product scratches caused by narrow operating space during retrieval, improving product quality and hanging efficiency. It also makes full use of the carrying space of the hanging position, increasing the number of electroplated products that can be hung within the same capacity, thereby improving production efficiency per unit time. On the other hand, the cooperation and fixation of the movable upper cover and the hanging position when closed ensures the stability of the product on the hanging position during electroplating, reduces the impact of product shaking on the uniformity of electroplating, and ensures electroplating quality. Moreover, the overall structure does not rely on external auxiliary fixing or operating components, simplifying the use process of the hanger, reducing operational complexity and additional costs, and better meeting the needs of the electroplating and automation industries for efficient, stable, and low-cost use of hangers.

[0008] Optionally, the movable upper cover is provided with a first barb and a second barb, and the corresponding position of the lower body is provided with a first slot adapted to the first barb and a second slot adapted to the second barb; or, the lower body is provided with a first barb and a second barb, and the corresponding position of the movable upper cover is provided with a first slot adapted to the first barb and a second slot adapted to the second barb; when the movable upper cover is in the closed state, the first barb engages with the first slot, and the second barb engages with the second slot; during the opening operation, the first barb always remains engaged with the first slot, and the movable upper cover flips relative to the lower body with the engagement point of the first barb and the first slot as the fulcrum, so that the second barb disengages from the second slot; during the closing operation, the movable upper cover flips back to its original position relative to the lower body, and the second barb re-engages with the second slot, restoring the engagement with the lower body.

[0009] By adopting the above technical solution, the continuous engagement of the first barb and the first slot ensures that the movable top cover always uses this engagement point as a fixed fulcrum during the opening and closing process, ensuring stable and non-offset flipping action and avoiding operational difficulties caused by fulcrum shaking during opening and closing. The second barb and the second slot can be disengaged and engaged by simply flipping action, without relying on elastic deformation, making the structure simpler and more reliable, and reducing the risk of failure due to deformation fatigue. At the same time, the double barb engagement design can form double fixation in the closed state, improving the connection stability between the movable top cover and the lower body, effectively preventing the top cover from loosening due to vibration and chemical impact during electroplating, ensuring the product fixation effect, and the opening and closing operation can be completed by simply flipping action, which is simple and convenient for quick operation by manual or automated equipment, improving the efficiency of hanging and unhanging.

[0010] Optionally, the first and second barbs are made of rigid steel, and the first and second barbs are integrally formed with the movable upper cover or lower body.

[0011] By adopting the above technical solution, the first and second barbs made of rigid steel, combined with the integral molding design with the main body, ensure that the barbs have sufficient structural strength, avoiding deformation or breakage during snapping or flipping. The integral molding process eliminates the assembly process between the barbs and the main body, reducing the number of parts and assembly errors, improving the production efficiency and structural accuracy of the hanger, while avoiding chemical residue and corrosion problems caused by splicing gaps, extending the service life of the hanger, and making it more suitable for working environments that are immersed in electroplating solutions for a long time. The barbs made of high-elasticity steel can produce moderate elastic deformation in the closed state, so that the connection surface between the movable upper cover and the lower main body is highly fitted, ensuring the stability of the conductive contact between the two. During the electroplating process, the current can be conducted through the electroplating equipment to the movable upper cover, through the fitted barbs and the slot connection structure to the lower main body, and finally accurately conducted to the electroplated product on the hanger, forming an efficient conductive path. The close fit provided by this highly elastic steel reduces contact resistance during current conduction, which not only improves conductivity but also helps ensure the uniformity of current distribution among products, further optimizing the quality of the electroplating layer. At the same time, the one-piece molding process avoids the risk of conductive breakage caused by splicing gaps. Combined with the corrosion resistance of the steel itself, it ensures the stability of conductivity during long-term use, making it more suitable for the high reliability requirements of electroplating production.

[0012] Optionally, the first barb is provided in a plurality of parts, and the second barb is provided in a plurality of parts.

[0013] By adopting the above technical solution, the cooperation of several first barbs and several second barbs can form a multi-point snap-fit ​​structure between the movable upper cover and the lower body. Compared with the locking method of a single barb, this significantly improves the connection stability after the two are closed, effectively preventing the upper cover from shifting due to the loosening of a single barb caused by the vibration of the hanger and the impact of the chemical solution during the electroplating process. This prevents the electroplated products on the hanger from shifting or shaking, ensuring the positional accuracy of the products during electroplating and reducing quality problems such as uneven electroplating and incomplete plating caused by positional deviations. At the same time, the multi-point snap-fit ​​can distribute the locking force to each barb, preventing a single barb from bearing excessive stress for a long time. Combined with the fatigue resistance of the steel used for the barbs, this further enhances the stability of the connection. This reduces the risk of fatigue failure of the barbs due to local overload, extends the service life of the barbs and even the entire hanger, and reduces the frequency and cost of hanger maintenance and replacement. In addition, the arrangement of multiple barbs can be flexibly adjusted in terms of distribution spacing and number according to the length of the hanger, the size of the electroplated products, and their arrangement. For example, multiple sets of barbs can be evenly arranged on a long hanger to ensure consistent locking force in different areas of the hanger, or the number of barbs can be increased according to the density of products to strengthen the local limiting effect. This enhances the adaptability of the hanger to electroplated products of different specifications and arrangements, eliminates the need to design locking structures separately for specific products, improves the versatility and flexibility of the hanger, and better adapts to the diverse production needs in automated electroplating production lines.

[0014] Optionally, the shape of the hanging position is adapted to the shape of the electroplated product to achieve positioning, and the hanging position is provided with a bifurcated positioning structure so that the electroplated product can be arranged and fixed in multiple layers along the hanging position.

[0015] By adopting the above technical solution, the shape of the mounting position is adapted to the shape of the electroplated product (ring-shaped closed or semi-closed electroplated product, such as the metal shell of a Type-C connector), which allows the product to be accurately embedded in the mounting position. This avoids the product shifting or shaking due to vibration or chemical impact during the electroplating process, ensuring the stability of the contact between the product's electroplating area and the current. It also reduces quality problems such as localized missed plating and uneven plating thickness caused by positional deviations, significantly improving electroplating accuracy. At the same time, the bifurcated positioning structure on the mounting position breaks the limitation of traditional single-piece mounting fixtures that can only arrange products in a single layer. It allows products to be arranged in multiple layers along the mounting position in an orderly manner. There is no need to reserve redundant hanging space in the same mounting space, which greatly increases the number of products that can be hung at one time, significantly improving the space utilization rate of the mounting fixture and the production efficiency per unit time. In addition, the bifurcation not only enables layering but also provides independent positioning and fixation for each layer of products, preventing surface scratches caused by friction and collision between multiple layers of products, thus further ensuring the appearance quality of the products. Furthermore, the orderly arrangement of multiple layers facilitates precise grasping by automated equipment or rapid manual handling, reducing operational errors and time costs. It is more suitable for the high-efficiency and high-quality production needs of the electroplating industry, providing support for the continuous and stable operation of automated electroplating production lines.

[0016] Optionally, when the movable top cover is in the closed state, the gap between it and the end of the hanging position is smaller than the size of the electroplated product along the length of the hanging position, so as to prevent the electroplated product from sliding out along the length of the hanging position.

[0017] By adopting the above technical solution, the gap size formed between the movable top cover and the end of the mounting position when closed is limited, which can physically block the electroplated product (ring-shaped closed or semi-closed electroplated product, such as the metal shell of a Type-C connector) from the length direction of the mounting position. This effectively avoids the product from sliding or even falling off the mounting position due to vibration, chemical impact, or shaking during the electroplating process, reducing scrap losses and production interruptions caused by product drops and ensuring production continuity. More importantly, the reduced gap size significantly reduces the distance between the movable top cover and the electroplated product on the top layer of the mounting position. Utilizing the electric field shielding effect of the conductor at close range, a stronger current shielding effect can be formed on the non-electroplated areas of the top layer product. This design shortens the distance between the conductor and the non-plating area, reducing current dispersion into the non-plating area and lowering the risk of accidental plating. It improves plating accuracy without relying on additional shielding components. Furthermore, this gap-limiting mechanism eliminates the need for complex fixing structures like clips or blocks; the limiting function is achieved simply by matching the dimensions of the top cover and the hanging position. This simplifies the overall design of the hanger and avoids interference from additional structures during product handling – products can be directly placed or removed after opening the top cover without first removing the limiting components, further improving the efficiency of hanging products. In addition, for multi-layered products, this gap effectively limits the products near the end of each layer, preventing outer layers from sliding due to lack of constraint. This ensures the stability of multi-layered arrangements, maximizing space utilization without sacrificing product fixation. It also prevents surface scratches caused by friction between sliding products, balancing production efficiency and product appearance quality. This design is particularly suitable for the stable fixation and efficient flow of products in automated electroplating production lines.

[0018] In summary, this application has at least the following beneficial effect: 1. The openable design of the movable top cover and lower body significantly increases the operating space of the hanging position when open, eliminating the need for redundant space for hanging operations as required by existing single-piece hangers. This facilitates the rapid hanging of products to be electroplated and the convenient retrieval of products after electroplating, effectively preventing product scratches caused by narrow operating space during retrieval, improving product quality and hanging efficiency. It also fully utilizes the carrying capacity of the hanging position, increasing the number of electroplated products that can be hung within the same capacity, thereby increasing production efficiency per unit time. On the other hand, the movable top cover and the hanging position are fixed together when closed, ensuring the stability of the product on the hanging position during electroplating, reducing the impact of product shaking on electroplating uniformity, and ensuring electroplating quality. Moreover, the overall structure does not rely on external auxiliary fixing or operating components, simplifying the use of the hanger, reducing operational complexity and additional costs, and better meeting the needs of the electroplating and automation industries for efficient, stable, and low-cost hangers.

[0019] 2. The continuous engagement of the first barb and the first slot ensures that the movable top cover always uses this engagement point as a fixed fulcrum during opening and closing, guaranteeing stable and non-offset flipping action and avoiding operational difficulties caused by fulcrum wobbling during opening and closing. The second barb and the second slot can be disengaged and engaged simply by flipping, without relying on elastic deformation, making the structure simpler and more reliable, and reducing the risk of failure due to deformation fatigue. At the same time, the double barb engagement design can form double fixation in the closed state, improving the connection stability between the movable top cover and the lower body, effectively preventing the top cover from loosening due to vibration and chemical impact during electroplating, ensuring the product's fixation effect. Moreover, the opening and closing operation can be completed with just a flipping action, which is simple and convenient for quick operation by manual or automated equipment, improving the efficiency of hanging and unhanging.

[0022] The present application will be further described in detail below with reference to the accompanying drawings.

[0023] Example 1 In this embodiment, refer to Figures 1-3 An electroplating rack includes a lower body 1 and a movable upper cover 2. The movable upper cover 2 is connected to the lower body 1 via a movable connecting structure, allowing them to move relative to each other to switch between open and closed states. This achieves the beneficial effects of facilitating the loading and unloading of electroplated products, increasing the number of products that can be hung, and utilizing the rack's own structure to shield current. This is because when the movable upper cover 2 is open, it increases the operating space of the hanging position 3, making it easier to load and unload products; there is no need to reserve a dedicated hanging space, allowing more products to be hung in the same space; and the rack's own structure can shield current. Preferably, the electroplated products are annular closed or semi-closed electroplated products, such as Type-C connector metal shells.

[0024] Specifically, the lower body 1 has a mounting position 3 along its length for supporting electroplated products. The shape of the mounting position 3 is adapted to the shape of the electroplated product to achieve positioning. For example, for a round electroplated product, the mounting position 3 can be designed as an arc-shaped groove; for a square electroplated product, the mounting position 3 can be designed as a square slot. The mounting position 3 has a forked positioning structure, which can be similar to the shape of a branch, allowing the electroplated product to be arranged and fixed in multiple layers along the mounting position 3. For example, some protrusions or depressions can be set at the forks to match specific parts of the electroplated product, thereby achieving multi-layer arrangement and fixation.

[0025] When the movable top cover 2 is closed, the gap 8 formed between it and the end of the hanging position 3 is smaller than the length of the electroplated product along the hanging position 3, thus preventing the electroplated product from sliding out along the length of the hanging position 3. The movable top cover 2 serves to seal and fix the electroplated product, ensuring the stability of the product during the electroplating process.

[0026] The movable upper cover 2 is provided with a first barb 4 and a second barb 5. The lower body 1 is provided with a first slot 6 that matches the first barb 4 and a second slot 7 that matches the second barb 5 (or the lower body 1 can be provided with a barb and the movable upper cover 2 with a slot). The first barb 4 and the second barb 5 are made of rigid steel and are integrally formed with the movable upper cover 2 or the lower body 1. The dimensions of the barbs and the slots are matched with precision to ensure a tight engagement and to allow for disengagement and reset through a flipping action, thus ensuring the strength and stability of the structure.

[0027] Several first barbs 4 and several second barbs 5 are provided. For example, two large and two small barbs can be set on both sides of the movable top cover 2 to achieve vertical and horizontal limiting functions. When the movable top cover 2 is in the closed state, the first barb 4 engages with the first slot 6, and the second barb 5 engages with the second slot 7, tightly connecting the movable top cover 2 and the lower body 1 together. During the opening operation, the first barb 4 is always engaged in the first slot 6 and kept fixed. Applying a flipping force to the side of the movable top cover 2 away from the first barb 4 will cause the movable top cover 2 to flip relative to the lower body 1 with the first barb 4 as the fulcrum. At this time, the second barb 5 will naturally disengage from the second slot 7 as the top cover flips. During the closing operation, flip the movable top cover 2 in the opposite direction. When the second barb 5 is aligned with the second slot 7, continue to flip so that the second barb 5 re-engages in the second slot 7, completing the closing and fixing.

[0028] The implementation principle of this embodiment is as follows: This electroplating rack utilizes its own structure to achieve the function of shielding current, saving the cost and operational complexity of manually attaching external shielding structures. Since the rack's top cover can be opened, there is no need to reserve space for hanging products, allowing more products to be hung within the same space, thus increasing the production quantity per rack. The openable design allows for direct removal of products from the rack, accelerating the unloading process and avoiding scratches when carefully handling products, thereby improving product quality. The selection of rigid steel and the precise dimensional matching of the barbs and slots avoid fatigue failure caused by elastic deformation, resulting in a rack service life of over 100,000 cycles and superior structural stability, representing a significant improvement and enhancement compared to existing technologies.

[0029] Example 2 The structural framework of this embodiment is basically the same as that of embodiment 1. The core difference is that the shape of the hanging position is adapted to the shape of the product to be electroplated. Taking the adapted electroplated product as a non-Type-C connector hardware product such as a power plug hardware as an example, the other structures and connection relationships such as the movable top cover, the way the barb and the slot are matched, and the gap limit are the same as those in embodiment 1. The following only explains the principle of the difference.

[0030] Reference Figure 4 In this embodiment, the mounting bracket on the lower body no longer adopts the outline of the metal shell of the Type-C connector, but is designed with a corresponding fitting shape according to the shape characteristics of the power plug hardware (such as having prongs, the shell having a specific geometric shape, etc.), so that the power plug hardware can be naturally embedded in the mounting bracket. The initial positioning is achieved by the fitting of the mounting bracket with the product shape. At the same time, the fitting shape of the mounting bracket can also cover the non-plating areas of the power plug hardware (such as the root of the prongs, the connection between the shell and the plastic base). After the product is embedded, the mounting bracket itself can block the non-plating areas from contacting the plating solution and current, thereby achieving current shielding without the need for additional shielding components.

[0031] The implementation principle of this embodiment is as follows: by adjusting the shape of the hanging position to adapt to electroplating products with different contours (such as power plug hardware), without changing the overall structure of the hanger (movable top cover, barbed slot, etc.), the core functions of "product positioning, current shielding, and multi-layer arrangement" are achieved by utilizing the adaptability of the hanging position to the product shape. This ensures the universality of the hanger for different types of electroplating products and continues the advantages of "convenient pick-up and drop, stable fixation, and efficient electroplating" in Embodiment 1, making it suitable for more diverse electroplating production scenarios.

[0032] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
