Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of U-shaped busbar production and processing, and particularly relates to a U-shaped busbar electroplating equipment capable of eliminating a hanging blind area and an electroplating method. BACKGROUND

[0002] The U-shaped busbar is a key conductive element widely used in power transmission and distribution systems. It is mainly used for connecting and distributing high-voltage or low-voltage current to ensure the stable operation of the power system. Due to its simple structure, strong current-carrying capacity, and good heat dissipation performance, the U-shaped busbar plays an important role in the electrical systems of industrial, commercial buildings, data centers, and other places. In actual electroplating production, the parts to be electroplated in the U-shaped busbar are usually long strip-shaped, and there are some through holes in the length direction. These through holes not only help the heat dissipation and installation of the busbar, but also play a key role in the electroplating process.

[0003] Electroplating is a surface treatment process that deposits a thin layer of metal on the surface of a metal by electrolysis to improve its corrosion resistance, wear resistance, and electrical conductivity. Its principle is to place the metal to be plated as the cathode in the electroplating solution containing the target metal ions, and to make the metal ions reduce and deposit on the surface of the cathode by applying an external current to form a plating layer.

[0004] During electroplating treatment, the electroplated parts are hung on the hooks through the through holes in the length direction, so that the electroplating solution can uniformly cover the entire surface of the parts. However, when the through holes are immersed in the electroplating solution, water films and bubbles are easily formed. These water films and bubbles hinder the flow of the electroplating solution in the through holes, causing the electroplating solution to not uniformly cover the inner wall of the through holes. These factors can all lead to the formation of electroplating blind areas, which can affect the electroplating quality and performance of the busbar. To address this issue, some electroplating equipment sets up stirring devices in the electroplating tank to improve the flowability of the electroplating solution and prevent the formation of water films and bubbles. However, this hanging method is obstructed by the hooks passing through the through holes, as the presence of the hooks in the through holes greatly reduces the effective conduction area of the through holes, making it difficult for the electroplating solution to flow smoothly through the through holes, which can result in the presence of local electroplating blind areas in the through holes.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0020] In addition, the elements in the present application are referred to as "fixed to" or "provided on" another element, which can be directly on another element or can have a middle element. When an element is considered to be "connected" to another element, it can be directly connected to another element or can have a middle element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not the only implementation.

[0021] Please refer to Figures 1-10 In the embodiments of the present application, a U-shaped busbar row electroplating equipment for eliminating suspension blind area comprises an electroplating tank 1 and a truss 2, further comprising: a horizontal moving frame 3 movably arranged on the truss 2, the horizontal moving frame 3 being capable of moving along the length direction of the truss 2, and the horizontal moving frame 3 being provided with a horizontal table 5 capable of lifting; a vertical plate 7 fixed to the bottom of the horizontal table 5, both sides of the vertical plate 7 being provided with a plurality of column bodies 12 distributed equidistantly from top to bottom, the column bodies 12 being used for hanging components to be electroplated, and the column bodies 12 being capable of being driven by an elastic mechanism arranged on the vertical plate 7 to move towards or away from the vertical plate 7; limiting pieces 15 symmetrically arranged on both sides of the column bodies 12, the limiting pieces 15 being capable of moving towards the column bodies 12 to enable the components to be located between the limiting pieces 15 and limiting rings 1201 arranged on the column bodies 12; a clamping mechanism arranged on the vertical plate 7, the clamping mechanism being capable of performing a clamping action on the components, and after the clamping action is completed, triggering the elastic mechanism to enable the elastic mechanism to drive the column bodies 12 to move towards the vertical plate 7, and the column bodies 12 to be separated from the through holes in the components.

[0022] It needs to be explained that the electroplating tank 1 is also provided with a stirring mechanism (not shown in the figure), which is used to improve the flowability of the electroplating solution in the electroplating tank 1 during the electroplating process. The bottom of the cross-moving frame 3 is also fixed with two vertical columns 4. The cross table 5 is slidingly connected with the two vertical columns 4. The side of the cross-moving frame 3 is also provided with a linear drive module. The linear drive module drives the cross table 5 to slide on the vertical column 4 by means of a screw rod, so as to drive the parts to be immersed in the electroplating tank 1 or taken out of the electroplating tank 1.

[0023] Secondly, in the actual electroplating process, the parts will usually go through the following tanks in sequence before entering the electroplating tank 1: degreasing tank: the parts are first immersed in the degreasing tank, and chemical degreasing agent is used to remove the oil, dirt and other organic contaminants on the surface, ensuring the surface to be clean; water washing tank: the parts are washed with clean water in the water washing tank to remove residual degreasing agent, preventing it from affecting the subsequent processing effect; pickling tank: the parts enter the pickling tank, and an acidic solution is used to remove the surface scale, rust and old coating, making the surface clean and activated; water washing tank: the parts are washed with clean water in the water washing tank again to remove residual acid solution, avoiding the acid solution from interfering with the subsequent process; activation tank: the parts are immersed in the activation tank for a short time, and an activation solution is used to further activate the surface, improving its conductivity and chemical activity, and preparing for electroplating; water washing tank: the parts are finally washed with deionized water or distilled water in the water washing tank to ensure that the surface is completely clean and free of residual chemicals, thereby ensuring the uniform adhesion and good quality of the electroplated layer. These pretreatment steps are crucial for ensuring the adhesion and uniformity of the electroplated layer, and each step aims to create the best conditions for the final electroplating process. In actual electroplating processing, a degreasing tank, a water washing tank, a pickling tank, etc. are arranged side by side with the electroplating tank 1. Correspondingly, the truss 2 is provided with guide rails, and the cross-moving frame 3 is provided with walking wheels 6 adapted to the guide rails. The walking wheels 6 are driven by a servo motor, which can move the cross-moving frame 3 above the multiple processing tanks, so that the parts can go through each treatment one by one.

[0024] Further, in the processing, the component is hung on the column 12 through the through hole on the component, then the limiting piece 15 moves towards the column 12 to the side of the component away from the limiting ring 1201, thus the component is limited between the limiting ring 1201 and the limiting piece 15, avoiding the component from sliding off the column 12 in the process of the horizontal table 5 descending; then the horizontal table 5 moves downwards, thus the component is immersed in the electroplating tank 1, in the processing, the clamping mechanism works to clamp the component between the limiting piece 15 and the limiting ring 1201, and separates the two sides of the component from the limiting ring 1201 and the limiting piece 15 respectively, after the clamping action of the clamping mechanism is completed, the elastic mechanism is triggered, the elastic mechanism will drive the column 12 to move towards the vertical plate 7 until the column 12 is separated from the through hole on the component, thus the through hole for hanging can be completely separated from the column 12, the through area of the through hole is recovered, under the flow of the electroplating liquid, the through hole can be fully electroplated, effectively avoiding the problem of local electroplating blind area caused by the conventional hanging electroplating means, ensuring the electroplating quality and performance of the final busbar row.

[0025] Please refer to Figure 6 , the side of the vertical plate 7 is fixed with a double-head pneumatic cylinder 13, two movable ends of the double-head pneumatic cylinder 13 are respectively fixed with a second vertical arm 14, the limiting piece 15 is fixedly installed on the second vertical arm 14, and an arc-shaped notch is arranged at the end of the limiting piece 15 away from the second vertical arm 14.

[0026] After the component to be electroplated is hung on the column 12, the movable ends of the double-head pneumatic cylinder 13 perform the contraction action, thus the two second vertical arms 14 connected with the two movable ends of the double-head pneumatic cylinder 13 move close to each other, and then the limiting pieces 15 on the two sides of each column 12 move close to each other to the side of the component away from the vertical plate 7, at this time, the component is limited between the limiting pieces 15 and the limiting ring 1201, avoiding the problem that the component slides off the column 12 due to instability in the process of the horizontal table 5 descending; in addition, it should be noted that in the subsequent electroplating process, the column 12 needs to be separated from the through hole on the component by the elastic mechanism to make the through hole completely conductive, avoiding the problem of electroplating blind area, and the existing hook is usually provided with a bent front end (for preventing the component from sliding off), thus the existing hook cannot be smoothly separated from the through hole on the component, thereby cannot avoid the electroplating blind area, the limiting piece 15 is arranged in the present application, which effectively avoids the problem that the component slides off, and can ensure that the through hole for hanging on the component can be separated from the column 12 in the electroplating process.

[0027] Please refer to Figure 6 ,Figure 7 And Figure 9 The clamping mechanism includes two groups of driven structures respectively arranged on both sides of the vertical plate 7, and each group of driven structures is connected with a group of power assemblies. The power assembly can drive the driven structure to move towards the vertical plate 7. The driven structure includes a guide plate 16 fixed to the side of the vertical plate 7 and a telescopic plate 17 slidingly fitted with the guide plate 16. The telescopic plate 17 is arranged in a "L" shape, and a plurality of clamping pieces 19 are arranged on one side of the telescopic plate 17 facing the vertical plate 7. The clamping piece 19 is fixed with the telescopic plate 17 through a connecting arm 18.

[0028] Please refer again to Figure 10 The side of the clamping piece 19 away from the connecting arm 18 is provided with a groove. The groove includes a first slot 1901 and a second slot 1902 in communication with the first slot 1901. The cross section of the first slot 1901 is in a "V" shape, and the second slot 1902 is in a long strip shape.

[0029] In detail, after the limiting piece 15 moves towards the column 12, the component is limited between the limiting ring 1201 and the limiting piece 15. However, in order to avoid that the limiting ring 1201 and the limiting piece 15 cause a large shielding to the component during electroplating, the gap between the limiting piece 15 and the limiting ring 1201 is larger than the thickness of the component, so that the component has a certain movement space between the limiting piece 15 and the limiting ring 1201. During the electroplating process, the power assembly works, and under the guidance of the guide plate 16, the telescopic plate 17 and the guide plate 16 can slide relatively, that is, the telescopic plate 17 slides towards the inside of the guide plate 16. Correspondingly, the clamping piece 19 moves towards the component by synchronously moving with the telescopic plate 17 through the connecting arm 18. The cross section of the first slot 1901 is in a "V" shape, that is, an open setting, and the range of the opening covers the movement range of the component between the limiting piece 15 and the limiting ring 1201. Therefore, the inclined surface of the first slot 1901 will contact the component, so that the component gradually corresponds to the second slot 1902, and finally the second slot 1902 matches the side of the component, so that the component can be clamped. The setting of the first slot 1901 can regularize the component during clamping, so that the component is clamped at the middle position between the limiting piece 15 and the limiting ring 1201, so that it can be ensured that the two sides of the component are separated from the limiting piece 15 and the limiting ring 1201. Especially, it can avoid that the component is too close to or adheres to the limiting piece 15 after the column 12 is separated from the through hole of the component, so as to cause the problem of electroplating blind area again, resulting in uneven electroplating.

[0030] Please refer againFigure 7 The power assembly comprises a single-head cylinder 20 fixedly installed on the horizontal table 5 and a driving frame 21 fixed to a movable end of the single-head cylinder 20, and a sliding fit structure is arranged between the driving frame 21 and the telescopic plate 17, and a rolling fit structure is arranged between the driving frame 21 and the elastic mechanism.

[0031] Please refer again to Figure 8 The elastic mechanism comprises a protruding block 8 fixed to a side of the vertical plate 7, a horizontal rod 9 fixed to the protruding block 8, and two cylindrical springs 10 sleeved on the horizontal rod 9 and respectively located on two sides of the protruding block 8; wherein two first vertical arms 11 are symmetrically arranged on the horizontal rod 9 and slide, a column body 12 is fixed to the first vertical arm 11, and two ends of the cylindrical spring 10 are respectively connected to the protruding block 8 and the first vertical arm 11.

[0032] The rolling fit structure comprises a driving wheel 2102 installed on the driving frame 21, the driving wheel 2102 is matched with a protruding part 1101 fixed to the first vertical arm 11, the protruding part 1101 is in a strip shape and is arranged obliquely, and when the driving wheel 2102 rolls downward along the protruding part 1101, the protruding part 1101 can drive the first vertical arm 11 to move towards the protruding block 8.

[0033] Specifically, in the working process, the single-head cylinder 20 drives the driving frame 21 to move downward, correspondingly, the driving wheel 2102 gradually approaches the protruding part 1101, before the driving wheel 2102 contacts the protruding part 1101, the sliding fit structure is triggered, so that the telescopic plate 17 and the guide plate 16 slide relatively, that is, the telescopic plate 17 slides towards the guide plate 16, and the clamping part 19 performs a clamping action on the component; then, the driving wheel 2102 contacts the protruding part 1101, thereby causing the protruding part 1101 and the first vertical arm 11 to be disengaged, specifically, the first vertical arm 11 slides on the horizontal rod 9 towards the protruding block 8, the cylindrical spring 10 is compressed, and the first vertical arm 11 drives the column body 12 to be separated from the through hole in the component, so as to ensure that the through hole is completely open, and under the flow of the electroplating liquid, the through hole can be comprehensively electroplated, effectively avoiding the problem of local electroplating blind area caused by the conventional suspension electroplating method.

[0034] Please refer again to Figure 7The sliding fit structure comprises a transmission plate 22 fixedly installed on the telescopic plate 17 away from the vertical plate 7 and a driving column 2101 fixed to the driving frame 21, and the transmission plate 22 is provided with a through groove matched with the driving column 2101; wherein the driving column 2101 penetrates through the through groove and is in sliding connection with the transmission plate 22, and the through groove comprises an inclined groove 2201 and a vertical groove 2202 connected with each other.

[0035] During the driving of the driving frame 21 to move downward, the driving column 2101 will sequentially pass through the inclined groove 2201 and the vertical groove 2202, and when the driving column 2101 slides in the inclined groove 2201, the driving column 2101 will slide with the transmission plate 22 to make the transmission plate 22 drive the telescopic plate 17 to move aside, that is, the telescopic plate 17 slides toward the inside of the guide plate 16, and after the driving column 2101 is separated from the inclined groove 2201, the clamping piece 19 completes clamping of the component. During the above process, the driving wheel 2102 does not contact the protruding part 1101, and after the driving column 2101 is in the vertical groove 2202, the driving wheel 2102 contacts the protruding part 1101 to make the first vertical arm 11 move aside and drive the column body 12 to separate from the through hole of the component. Therefore, during the electroplating process, the clamping piece 19 first clamps the component, and then the column body 12 separates from the through hole of the component, thereby avoiding the problem of electroplating blind area of the component and ensuring the electroplating effect.

[0036] In addition, it should be noted that the vertical plate 7 is long enough, and when the mounted component moves downward and is immersed in the electroplating solution, in the current state, part of the structure (for example, the transmission plate 22) in the application is above the electroplating solution (that is, the transmission plate 22 is not finally immersed in the electroplating solution), thereby eliminating the adverse effects of the electroplating solution on the cooperation precision of part of the structure. In actual electroplating treatment, the related problems can be avoided by controlling the downward stroke of the horizontal table 5 and the liquid level of the electroplating solution in the electroplating tank 1.

[0037] As another embodiment of the application, a U-shaped busbar electroplating method is also provided, which adopts the electroplating equipment and comprises the following steps: Step one: suspending the component on the column body 12 through the through hole of the component to be electroplated; Step two: moving the limiting piece 15 toward the column body 12 to limit the component between the limiting ring 1201 and the limiting piece 15; Step three: moving the horizontal table 5 downward to immerse the component in the electroplating tank 1; Step four: moving the clamping mechanism to work, and moving the clamping piece 19 toward the component to clamp the component, so that the component is stably arranged at the middle of the limiting ring 1201 and the limiting piece 15. Step five, the elastic mechanism is triggered, the column 12 is driven to move towards the vertical plate 7, the column 12 is pulled out of the through hole on the component, and the through hole is completely open; Step six, the plating is completed, the clamping mechanism and the elastic mechanism are reset, and the horizontal table 5 is raised to take off the component on the column 12 which has completed the plating treatment.

The U-shaped busbar electroplating equipment for eliminating suspension blind spots according to claim 6, characterized in that, The sliding fit structure includes a transmission plate fixedly installed on the side of the telescopic plate away from the vertical plate and a drive column fixed on the drive frame. The transmission plate is provided with a through groove adapted to the drive column. The drive column passes through the through groove and is slidably connected to the transmission plate. The through groove includes an inclined groove and a vertical groove connected together.

10. A method for electroplating a U-shaped busbar, using the electroplating equipment as described in claim 1, characterized in that, Includes the following steps: Step 1: Suspend the component on the column through the through-hole on the component to be electroplated; Step two, the limiting component moves toward the column, so that the component is restricted between the limiting ring and the limiting component; Step 3: Lower the horizontal platform to immerse the component in the electroplating bath; Step four: The clamping mechanism operates, and the clamping component moves toward the component to clamp it, stabilizing the component in the middle between the limiting ring and the limiting component. Step 5: The elastic mechanism is triggered, driving the column to move toward the vertical plate. The column is pulled out of the through hole on the component, making the through hole fully open. Step six: Electroplating is complete. The clamping mechanism and elastic mechanism reset, the horizontal platform rises, and the electroplated parts are removed from the column.
