Description

Technical Field

[0001] This invention belongs to the field of single-sided electroplating technology, and particularly relates to a single-sided electroplating device and its usage method. Background Technology

[0002] Electroplating is the process of depositing a thin layer of another metal or alloy onto the surface of certain metals using the principle of electrolysis. It utilizes electrolysis to coat the surface of metal or other material parts with a metallic film, thereby preventing metal oxidation (such as rust), improving wear resistance, conductivity, reflectivity, corrosion resistance (e.g., copper sulfate), and enhancing aesthetics. During electroplating, the plating metal or other insoluble material acts as the anode, and the workpiece to be plated acts as the cathode. The cations of the plating metal are reduced on the surface of the workpiece to form the electroplated layer. To eliminate interference from other plating metal cations and to ensure a uniform and firm coating, a solution containing plating metal cations is used as the electroplating bath to maintain a constant concentration of these cations. The purpose of electroplating is to deposit a metallic coating onto a workpiece, altering its surface properties or dimensions. Electroplating can enhance the corrosion resistance of metals (the plating metal is mostly made of corrosion-resistant metals), increase hardness, prevent wear, improve conductivity, smoothness, heat resistance and surface aesthetics. However, in practical applications, single-sided electroplating is often required. For example, some tubular metals often only need to be electroplated on their outer side.

[0003] Chinese utility model patent CN115558976A discloses a single-sided electroplating device. This technology scrapes off the electroplating solution from the bottom of a plate-shaped component, avoiding waste and preventing spillage. While this technology avoids waste, saves costs, and prevents spillage, scraping off excess solution can damage or wear the component, resulting in a substandard product. Therefore, to address these issues, a single-sided electroplating device and its method are provided that eliminate the need to scrape off excess solution from the workpiece's surface to prevent damage. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a single-sided electroplating device and its usage method that eliminates the need to scrape off excess electroplating solution from the electroplated surface of a workpiece, thereby ensuring that the workpiece is not damaged.

[0005] In view of this, the present invention provides a single-sided electroplating apparatus and its method of use, comprising an electroplating tank and a workpiece body disposed on the electroplating tank, characterized in that:

[0006] The support frame has two parts, which are respectively set on both sides of the electroplating tank;

[0007] Mounting plate, mounted on the support frame;

[0008] The first cylinder is located between the two mounting plates. The first cylinder drives the workpiece body to descend into the electroplating tank.

[0009] A rotating shaft is rotatably installed inside the electroplating bath, with one end passing through and extending out of the electroplating bath;

[0010] A roller brush is mounted on a rotating shaft;

[0011] The motor is mounted on a support frame on either side, and the motor output shaft is connected to the rotating shaft.

[0014] Support plate, located at the bottom of the support plate;

[0015] Side panels are located on the left and right sides of the bottom of the support plate;

[0016] The second cylinder is located on the side plate;

[0017] The clamping elements are located on the opposite sides of the two second cylinders, with the workpiece body positioned between the two clamping elements.

[0018] In any of the above technical solutions, the side plate is further composed of a left side plate and a right side plate, with the left side plate located on the bottom left side of the support plate and the right side plate located on the bottom right side of the support plate.

[0019] In any of the above technical solutions, a pipetting assembly is further included, the pipetting assembly comprising:

[0020] The movable plate consists of two pieces, which are slidably installed on the front and rear sides inside the electroplating tank, forming an installation groove between the movable plate and the electroplating tank.

[0021] Multiple electric linear actuators are installed in mounting slots, and the push rods of the electric linear actuators are connected to the moving plate.

[0022] In any of the above technical solutions, a liquid spraying assembly is further included, the liquid spraying assembly comprising:

[0023] The frame is located behind the electroplating tank;

[0024] The water pump is mounted on the frame;

[0025] The water pump pipe is located behind the water pump;

[0026] The water inlet pipe is located in front of the water pump and runs through the electroplating tank;

[0027] The connecting pipe is installed inside the electroplating tank and is connected to the water inlet pipe;

[0028] The regulating valve, a rotary type, is installed on the water pumping pipe;

[0029] The nozzles are multiple and evenly spaced on the connecting pipe.

[0030] In any of the above technical solutions, the regulating valve further includes:

[0031] A ball valve, which is rotary and installed inside the water pumping pipe;

[0032] The valve stem is rotatably mounted on the pumping pipe and passes through the pumping pipe to connect with the ball valve.

[0033] In any of the above technical solutions, a clamping component is further included, the clamping component comprising:

[0034] Top plate, located on top of the movable plate, at the top of the mounting groove;

[0035] Multiple sliding rods are mounted on the top plate.

[0036] A skateboard is mounted on top of a sliding bar;

[0037] The brackets are installed on the left and right sides of the top of the ceiling plate;

[0038] An elastic element is placed between the slide plate and the top plate and is fitted onto the slide bar. The elastic element provides a cushioning elastic force to the slide plate.

[0039] In any of the above technical solutions, the elastic element is further defined as a buffer spring.

[0040] In any of the above technical solutions, the following steps are further included:

[0041] Step S1: The roller brush rotates and contacts the electroplating surface of the workpiece, so that the roller brush evenly brushes the absorbed electroplating solution onto the electroplating surface of the workpiece, saving electroplating solution costs and avoiding immersing the workpiece in the electroplating bath and contacting the electroplating solution, which would cause excessive electroplating solution on the workpiece to overflow to the other side.

[0042] Step S2: Driven by the second cylinder, the clamping parts clamp the workpiece body to prevent the workpiece body from shifting, thereby enabling the clamping of workpiece bodies of different sizes and facilitating the electroplating of the workpiece body.

[0043] Step S3: By setting a movable plate in the electroplating tank, the movable plate effectively controls the space in the electroplating tank to hold the electroplating solution, minimizes the amount of electroplating solution used, is suitable for the electroplating needs of workpieces of different sizes, and reduces the cost of using the electroplating solution.

[0044] Step S4: By adjusting the valve to open and close the liquid inlet of the water pump, the electroplating solution is drawn out and drawn into the water inlet pipe. The solution flows from the water inlet pipe to the connecting pipe and is sprayed from the nozzle into the electroplating tank. When the electroplating solution in the electroplating tank is injected to an appropriate amount, the water pump is turned off.

[0045] Step S5: Rotate the valve stem to rotate the ball valve 90 degrees, so that the ball valve is connected to the water pump. At this time, the water pump can be started and the water pump can draw the electroplating solution. After rotating the valve stem to rotate the ball valve 90 degrees, the ball valve will close. At this time, there is no need to draw the electroplating solution.

[0046] Step S6: Support the roll-shaped component with a bracket. One side supports the material that has not been electroplated on the roll-shaped component, and the other side supports the roll-shaped component that has been electroplated. After the roll-shaped component is laid out, it comes into contact with the roller brush. The rotation of the roller brush can evenly brush the electroplating solution onto the electroplating surface of the roll-shaped component. Rotating the roll-shaped component that has been electroplated can transfer the material and more evenly pick up the electroplating solution.

[0047] The beneficial effects of this invention are:

[0048] 1. The first cylinder drives the workpiece body to move downwards until it contacts the roller brush. The motor drives the roller brush to rotate, and the electroplating solution absorbed by the brush is applied to the electroplating surface of the workpiece body. Since the sponge has a certain soft cotton-like texture after being wetted, when the wet roller brush contacts the workpiece body, it will make the roller brush imprint a depression, so that the workpiece body and the roller brush can be in contact more evenly. In this way, the workpiece body can be electroplated, while saving electroplating solution resources and avoiding the workpiece body being immersed in the electroplating tank and coming into contact with the electroplating solution, which would cause too much electroplating solution to overflow to the other side of the workpiece body.

[0049] 2. Driven by the second cylinder, the clamping parts clamp the workpiece body to prevent the workpiece body from shifting, thereby enabling the clamping of workpiece bodies of different sizes and facilitating the electroplating of the workpiece body.

[0050] 3. The moving plate is driven by an electric push rod to move inward along the electroplating tank, thereby reducing the space inside the electroplating tank for holding electroplating solution, minimizing the amount of electroplating solution used, suitable for the electroplating needs of workpieces of different sizes, reducing the cost of using electroplating solution, and saving resources.

[0051] 4. An external electroplating solution is drawn in by a water pump. The solution flows through a pumping pipe to the inlet pipe and is then discharged into a nozzle, from which it is sprayed into the electroplating tank. This achieves automated injection of electroplating solution into the electroplating tank, eliminating the need for manual operation and improving the efficiency of electroplating the workpiece. 5. A bracket supports the cylindrical component, facilitating single-sided electroplating of the rolled component. This allows for electroplating of workpieces of different specifications.

[0060] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0061] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items, and therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0062] Example 1:

[0063] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown, this embodiment provides a single-sided electroplating apparatus and its usage method, including an electroplating tank 1 and a workpiece body 2 disposed on the electroplating tank 1, characterized in that:

[0064] The support frame 3 has two parts, which are respectively set on both sides of the electroplating tank 1;

[0065] Mounting plate 4 is mounted on support frame 3;

[0066] The first cylinder 5 is located between the two mounting plates 4. The first cylinder 5 drives the workpiece body 2 to descend into the electroplating tank 1.

[0067] The rotating shaft 6 is rotatably installed inside the electroplating tank 1, with one end passing through and extending out of the electroplating tank 1;

[0068] Roller brush 7 is mounted on rotating shaft 6;

[0069] Motor 8 is mounted on support frame 3 on either side, and the output shaft of motor 8 is connected to rotating shaft 6.

[0070] In this technical solution, by making the roller brush 7 into a sponge material, the roller brush 7 can absorb the electroplating solution in the electroplating tank 1. When the roller brush 7 rotates, it contacts the electroplating surface of the workpiece body 2, thereby brushing the electroplating solution onto the electroplating surface of the workpiece body 2. Since the sponge has a certain softness after being wetted, when the wet roller brush 7 contacts the workpiece body 2, it will make the roller brush 7 imprint a depression, so that the workpiece body 2 and the roller brush 7 can be in contact more evenly. In this way, the workpiece body 2 can be electroplated. This avoids the problem in the prior art where the workpiece body 2 is immersed in the electroplating tank 1 and comes into contact with the electroplating solution, which causes too much electroplating solution to overflow to the other side of the workpiece body 2. Thus, it fundamentally solves the problem of the workpiece body 2 absorbing too much electroplating solution and overflowing to the other side during the electroplating process, which affects the electroplating operation of the workpiece.

[0071] Specifically, when electroplating the workpiece body 2, an appropriate amount of electroplating solution is first added to the electroplating tank 1, and the motor 8 is started. The output shaft of the motor 8 drives the rotating shaft 6 to rotate, and the rotating shaft 6 drives the roller brush 7 to rotate. Since the roller brush 7 is made of sponge material, it can absorb the electroplating solution in the electroplating tank 1. During the rotation of the roller brush 7, it can absorb the electroplating solution more evenly. Then, the first cylinder 5 is started, and the piston rod of the first cylinder 5 extends, causing the workpiece body 2 to move downward. The workpiece body 2 moves to contact the roller brush 7. At this time, the first cylinder 5 is closed, so that the workpiece body 2 stops moving. The roller brush 7 rotates and contacts the workpiece body 2, and brushes the electroplating solution onto the electroplating surface of the workpiece body 2. Since the sponge has a certain softness after being wetted, when the wet roller brush 7 comes into contact with the workpiece body 2, it can absorb the electroplating solution more evenly. When the workpiece body 2 comes into contact with the roller brush 7, it will cause the roller brush 7 to imprint a depression, making the contact between the workpiece body 2 and the roller brush 7 more uniform. After the workpiece body 2 is electroplated, the first cylinder 5 is started. The piston rod of the first cylinder 5 drives the workpiece body 2 to move upward and reset. The workpiece body 2 then moves until it is no longer in contact with the roller brush 7. At this time, the first cylinder 5 is turned off, and the electroplated workpiece body 2 is removed. The new workpiece body 2 is then electroplated. After the operation is completed, the motor 8 is turned off. Finally, the electroplating of the workpiece body 2 can be automated, which improves the efficiency of electroplating the workpiece body 2 and saves electroplating solution resources. It also avoids the workpiece body 2 being immersed in the electroplating tank 1 and coming into contact with the electroplating solution, which would cause too much electroplating solution to overflow to the other side of the workpiece body 2 and affect the pass rate of the workpiece body 2.

[0072] Example 2:

[0073] This embodiment provides a single-sided electroplating apparatus and its usage method, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0074] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the optimized version further includes a clamping assembly 9, which includes:

[0075] Support plate 91 is mounted on the piston rod of the first cylinder 5;

[0076] Support plate 92 is located at the bottom of support plate 92;

[0077] Side plates 93 are located on the left and right sides of the bottom of the support plate 91;

[0078] The second cylinder 94 is mounted on the side plate 93;

[0079] Clamping element 95 is located on the opposite side of the two second cylinders 94, and the workpiece body 2 is located between the two clamping elements 95.

[0080] In this technical solution, under normal conditions, the clamping members 95 on both sides clamp the workpiece body 2, making it less prone to displacement and ensuring more stable electroplating. When the first cylinder 5 is activated, its piston rod moves the support plate 91 downwards, which in turn moves the support disk 92 downwards. The support disk 92 then moves the side plate 93 downwards, which in turn moves the second cylinder 94 downwards. Simultaneously, the second cylinder 94 moves the clamping members 95 downwards, which in turn move the workpiece body 2 downwards. When the workpiece body 2 moves downwards and comes into contact with the roller brush 7, the roller brush 7 rotates, evenly applying the electroplating solution to the bottom of the workpiece body 2. After the workpiece body 2 is electroplated, people first hold the workpiece body 2, then start the second cylinder 94. The piston rod of the second cylinder 94 drives the clamping part 95 to move outward until it is separated from the workpiece body 2. At this time, the clamping part 95 will not clamp the workpiece body 2. People then remove the workpiece body 2 and replace it with a new workpiece body 2 that needs to be electroplated. The piston rod of the second cylinder 94 drives the clamping part 95 to move inward until it contacts the workpiece body 2. The clamping part 95 can then clamp the workpiece body 2. After the electroplating is completed, people close the first cylinder 5 and the second cylinder 94. In this way, the workpiece body 2 can be clamped to prevent the workpiece body 2 from shifting and to facilitate the movement of the workpiece body 2 for electroplating.

[0081] like Figure 4 As shown, in this embodiment, the optimized side plate 93 is composed of a left side plate and a right side plate, with the left side plate located on the bottom left side of the support plate 91 and the right side plate located on the bottom right side of the support plate 91.

[0082] In this technical solution, the second cylinder 94 is supported by the left and right side plates. A clamping element 95 is provided on the piston rod of the second cylinder 94. When the second cylinder 94 is started, the piston rod of the second cylinder 94 drives the clamping element 95 to move outward or inward, thereby clamping or releasing the workpiece body 2, which facilitates the electroplating of the workpiece body 2. In this way, the workpiece body 2 can be clamped, which is convenient to use.

[0083] like Figure 1 , Figure 5 and Figure 6 As shown, in this embodiment, the optimized version also includes a pipetting assembly 10, which comprises:

[0084] The movable plate 101 has two pieces, which are slidably disposed on the front and rear sides inside the electroplating tank 1, and an installation groove is formed between the movable plate 101 and the electroplating tank 1.

[0085] Multiple electric push rods 102 are provided in the mounting slot, and the push rod of the electric push rod 102 is connected to the movable plate 101.

[0086] In this technical solution, since the size of the current electroplating tank 1 is fixed, when electroplating workpieces 2 of different sizes, the electroplating tank 1 needs to be filled with electroplating solution so that the workpiece 2 can be fully immersed in the electroplating solution. In order to meet the electroplating requirements of large-sized products, the holding space inside the electroplating tank 1 is often large. However, when electroplating small-sized workpieces 2, a large amount of electroplating solution is also required in the electroplating tank 1, resulting in a great waste of electroplating solution, increasing the electroplating cost, and generating more electroplating waste liquid, which brings a greater workload to the subsequent waste liquid treatment. In addition, the electroplating solution in the electroplating tank 1 is mostly in a static state, and the concentration difference of the metal cations separated from the anode electrode plate in the electroplating solution is large, resulting in uneven coating thickness of the workpiece 2. Therefore, by setting a movable plate 101 inside the electroplating tank 1, the movable plate 101 effectively controls the space for holding electroplating solution inside the electroplating tank 1, minimizes the amount of electroplating solution used, is suitable for the electroplating needs of workpiece bodies 2 of different sizes, reduces the cost of using electroplating solution, and saves resources.

[0087] Specifically, when electroplating a smaller workpiece body 2 is required, the electric push rod 102 is activated. The push rod of the electric push rod 102 drives the moving plate 101 to move inward. The inward movement of the moving plate 101 reduces the space inside the electroplating tank 1 that holds the electroplating solution, thereby effectively reducing the amount of electroplating solution used. After the space inside the electroplating tank 1 that holds the electroplating solution is adjusted to a suitable width, the electric push rod 102 is turned off. At this time, the electroplating solution can be injected into the electroplating tank 1. After the appropriate amount of electroplating solution has been injected, the workpiece body 2 can be electroplated. After the electroplating is completed, the electric push rod 102 is turned off. In this way, the space inside the electroplating tank 1 that holds the electroplating solution can be reduced, thereby reducing the cost of using the electroplating solution, saving resources, and enabling the electroplating tank 1 to perform electroplating workpiece bodies 2 of different sizes.

[0088] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, in this embodiment, the optimized version also includes a spraying assembly 11, which comprises:

[0089] The frame 111 is located behind the electroplating tank 1;

[0090] Water pump 112 is mounted on frame 111;

[0091] The water pump 113 is located behind the water pump 112;

[0092] The water inlet pipe 114 is located in front of the water pump 112 and passes through the electroplating tank 1;

[0093] The connecting pipe 117 is installed inside the electroplating tank 1 and is connected to the water inlet pipe 114.

[0094] The regulating valve 115 is rotaryly mounted on the water pumping pipe 113;

[0095] The nozzles 116 are multiple and are evenly spaced on the connecting pipe 117.

[0096] In this technical solution, when it is necessary to inject electroplating solution into the electroplating tank 1, the pump 113 is first connected to the external electroplating solution tank. The flow of the pump 113 is opened and closed by the regulating valve 115, and the water pump 112 is started. The water pump 112 draws the electroplating solution from the external electroplating solution tank. The electroplating solution flows through the pump 113 to the inlet pipe 114, and then from the inlet pipe 114 to the connecting pipe 117. It is then sprayed out from the nozzle 116 and sprayed into the electroplating tank 1. After an appropriate amount of electroplating solution is injected into the electroplating tank 1, the water pump 112 is turned off, and the regulating valve 115 is adjusted to close the flow of the pump 113. In this way, the electroplating solution can be automatically injected into the electroplating tank 1 without manual operation.

[0097] like Figure 7 As shown, in this embodiment, the optimized regulating valve 115 includes:

[0098] Ball valve 12 is rotaryly installed inside the water pumping pipe 113;

[0099] The valve stem 121 is rotatably mounted on the pumping pipe 113 and passes through the pumping pipe 113 to connect with the ball valve 12.

[0100] In this technical solution, when the valve stem 121 is rotated, the ball valve 12 rotates 90 degrees. At this time, the ball valve 12 is connected to the water pump 113, and the water pump 112 is started to draw the electroplating solution. When the valve stem 121 is rotated 90 degrees again, the valve stem 121 rotates the ball valve 12 90 degrees. At this time, the ball valve 12 is closed, and the electroplating solution cannot flow. In this way, the flow of the electroplating solution can be controlled.

[0101] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 8 As shown, in this embodiment, the optimized component further includes a clamping assembly 13, which includes:

[0102] Top plate 131 is disposed on top of movable plate 101 and located at the top of mounting groove;

[0103] The slide bar 132 has multiple rods and is slidably mounted on the top plate 131;

[0104] Slide 133 is mounted on top of slide bar 132;

[0105] Bracket 134 is installed on the top left and right sides of the top plate 131;

[0106] An elastic element 135 is disposed between the slide plate 133 and the top plate 131 and is sleeved on the slide rod 132. The elastic element 135 provides a buffering elastic force to the slide plate 133.

[0107] In this technical solution, the roll-shaped component 14 is supported by the bracket 134. One side supports the material that has not been electroplated on the roll-shaped component 14, and the other side supports the roll-shaped component 14 that has been electroplated. After the roll-shaped component 14 is laid out, it comes into contact with the roller brush 7. The rotation of the roller brush 7 can evenly brush the electroplating solution onto the electroplating surface of the roll-shaped component 14. Rotating the roll-shaped component 14 that has been electroplated can transfer the material and more evenly pick up the electroplating solution.

[0108] Specifically, when electroplating the roll-shaped component 14 is required, the roll-shaped component 14 is first placed on the front support 134. The support 134 supports the roll-shaped component 14, and the weight of the roll-shaped component 14 exerts a force on the support 134, causing the support 134 to move the slide plate 133 downward. The slide plate 133 then moves the slide rod 132 downward along the top plate 131, compressing the elastic element 135. At this time, the roll-shaped component 14 fits more closely to the roller brush 7. Then, the empty roll is placed on the rear support 13. 4. Pull the front cylindrical component 14 to the rear to unfold the cylindrical component 14 and connect it to the empty drum on the rear. Rotate the empty drum on the rear to wind up the electroplated component. After the cylindrical component 14 is electroplated, it is removed. Under the reset action of the elastic element 135, the slide plate 133 drives the slide rod 132 to move upward and reset. The slide plate 133 drives the bracket 134 to move upward and reset. In this way, the cylindrical component 14 can be supported, which facilitates the electroplating of the cylindrical component 14.

[0109] like Figure 3 , Figure 5 and Figure 8 As shown, in this embodiment, the optimized elastic element 135 is a buffer spring.

[0110] In this technical solution, a return spring is used as the elastic element 135, which not only has good effect, but also has the characteristics of easy installation and low price, thus saving production costs.

[0111] like Figures 1-8 As shown, in this embodiment, the optimization includes the following steps:

[0112] Step S1: The roller brush 7 rotates and contacts the electroplating surface of the workpiece body 2, so that the roller brush 7 evenly brushes the absorbed electroplating solution onto the electroplating surface of the workpiece body 2, saving electroplating solution costs and avoiding immersing the workpiece body 2 in the electroplating tank 1 and contacting the electroplating solution, which would cause excessive electroplating solution on the workpiece body 2 to overflow to the other side.

[0113] Step S2: Driven by the second cylinder 94, the clamping part 95 clamps the workpiece body 2 to prevent the workpiece body 2 from shifting, thereby enabling the clamping of workpiece bodies 2 of different sizes, which facilitates the electroplating of the workpiece body 2.

[0114] Step S3: By setting a movable plate 101 in the electroplating tank 1, the movable plate 101 effectively controls the space for holding electroplating solution in the electroplating tank 1, minimizes the amount of electroplating solution used, is suitable for the electroplating needs of workpiece bodies 2 of different sizes, and reduces the cost of using electroplating solution.

[0115] Step S4: The liquid inlet of the water inlet pipe 113 is opened and closed by regulating valve 115. Under the action of water pump 112, the electroplating solution is drawn and drawn into water inlet pipe 114. The solution flows from water inlet pipe 114 to connecting pipe 117. The electroplating solution is sprayed into electroplating tank 1 from nozzle 116. When the electroplating solution in electroplating tank 1 is injected to an appropriate amount, the water pump 112 is turned off.

[0116] Step S5: Rotate valve stem 121 to drive ball valve 12 to rotate 90 degrees, so that ball valve 12 is connected to water pump pipe 113.

9. A method of using a single-sided electroplating apparatus according to any one of claims 1-8, characterized in that, Includes the following steps: Step S1: The roller brush (7) rotates and contacts the electroplating surface of the workpiece body (2), so that the roller brush (7) evenly brushes the absorbed electroplating solution onto the electroplating surface of the workpiece body (2), saving the cost of electroplating solution and avoiding immersing the workpiece body (2) in the electroplating tank (1) and contacting the electroplating solution, which would cause excessive electroplating solution on the workpiece body (2) to overflow to the other side. Step S2: Driven by the second cylinder (94), the clamping part (95) clamps the workpiece body (2) to prevent the workpiece body (2) from shifting, thereby enabling the clamping of workpiece bodies (2) of different sizes, which facilitates electroplating of the workpiece body (2). Step S3: By setting a movable plate (101) in the electroplating tank (1), the movable plate (101) effectively controls the space in the electroplating tank (1) for holding the electroplating solution, minimizes the amount of electroplating solution used, is suitable for the electroplating needs of workpiece bodies (2) of different sizes, and reduces the cost of using the electroplating solution. Step S4: The liquid inlet of the pump pipe (113) is opened and closed by the regulating valve (115). Under the action of the water pump (112), the electroplating solution is drawn and drawn into the water inlet pipe (114). The solution flows from the water inlet pipe (114) to the connecting pipe (117). The electroplating solution is sprayed from the nozzle (116) into the electroplating tank (1). When the electroplating solution in the electroplating tank (1) is injected to an appropriate amount, the water pump (112) is turned off. Step S5: Rotate the valve stem (121) to drive the ball valve (12) to rotate 90 degrees, so that the ball valve (12) is connected to the water pump (113). At this time, the water pump (112) can be started and the water pump (112) can draw the electroplating solution. After rotating the valve stem (121) again to drive the ball valve (12) to rotate 90 degrees, the ball valve (12) will be closed. At this time, there is no need to draw the electroplating solution. Step S6: The roll-shaped component (14) is supported by the bracket (134). One side supports the material that has not been electroplated on the roll-shaped component (14), and the other side supports the roll-shaped component (14) that has been electroplated. After the roll-shaped component (14) is laid out, it comes into contact with the roller brush (7). The roller brush (7) rotates so that the electroplating solution can be evenly brushed onto the electroplating surface of the roll-shaped component (14). Rotating the roll-shaped component (14) that has been electroplated can transfer the material and more evenly pick up the electroplating solution.
