Description

Technical Field

[0001] This utility model relates to the field of electroplating tank technology, and specifically discloses an electroplating tank for metal electroplating. Background Technology

[0002] Electroplating tanks are the most basic equipment in electroplating equipment. Their main function is to heat the solution and they are the core part of the electroplating production line. Electroplating tanks are usually composed of the tank body, heating and cooling devices for the solution, and stirring devices. The tank body is generally made of corrosion-resistant materials.

[0003] Chinese patent CN220537949U discloses a structure for an electroplating tank of metal materials, relating to the field of electroplating tanks. The structure includes an electroplating tank body with a drain pipe extending through its bottom. The drain pipe is equipped with a valve to control whether liquid is drained. A cleaning mechanism for removing residual liquid is installed inside the electroplating tank. This metal electroplating tank structure, through the arrangement of a cleaning scraper, a support frame, a drive mechanism, and a support bracket, allows the cleaning scraper to move up and down to clean the inner wall of the electroplating tank when the drive mechanism is rotated. The drive mechanism, nylon rope, and horizontal scraper further enhance the cleaning effect. When the rotating drive mechanism can move the horizontal scraper left and right to clean the bottom of the electroplating tank, it ensures that the inside of the electroplating tank is clean for the next use. However, the cleaning mechanism in the above-mentioned electroplating tank structure is located inside the electroplating tank body, which can easily affect the actual volume of the electroplating tank. During the metal electroplating operation, the electroplating liquid is easy to drip and adhere to the cleaning scraper and the horizontal scraper, which increases the workload of the user in cleaning the scraper and is not conducive to the scraper cleaning the electroplating tank body, thus affecting the effectiveness of the cleaning mechanism. Therefore, in order to solve the above problems, this utility model proposes an electroplating tank for metal electroplating. Utility Model Content

[0004] The present invention aims to provide an electroplating tank for metal electroplating, which can avoid affecting the actual volume of the electroplating tank body during the metal electroplating operation, and can prevent electroplating liquid dripping from the metal from falling onto the cleaning mechanism and the power mechanism. This reduces the workload of the user in cleaning the above-mentioned mechanisms, while helping the cleaning mechanism to clean the inner wall of the electroplating tank body, ensuring the effectiveness of the cleaning mechanism and the power mechanism.

[0005] This utility model is achieved through the following technical solution:

[0006] An electroplating tank for metal electroplating includes an electroplating tank body. A drain pipe is connected to the lower end of one end of the electroplating tank body, and a valve is installed at one end of the drain pipe. A U-shaped plate is connected to the upper part of the electroplating tank body away from the drain pipe. A cleaning mechanism is installed at the end of the electroplating tank body near the U-shaped plate. A power mechanism is installed on one side of the cleaning mechanism. The cleaning mechanism includes a scraper assembly. The scraper assembly includes a first support block. A mounting plate is connected to the upper part of the first support block. Multiple first support blocks arranged in a linear array are provided at both ends of the first support block. Two support blocks, with connecting blocks connected to the inner sides of both the second and first support blocks. A first scraper is provided below the connecting blocks, and two second scrapers are symmetrically connected below the first scraper. A first L-shaped column and a second L-shaped column are respectively provided at both ends of the scraper assembly. A third scraper is provided on the side of the second L-shaped column and the first L-shaped column that are far apart from each other. The power mechanism includes a telescopic rod and a bracket. A bracket is provided on the outer side of the telescopic rod. A slot is provided on both sides of one end of the bracket, and a threaded hole is provided at the bottom of the slot.

[0007] As a further provision of the above solution, each end of the first support block and the second support block is provided with a first slot and a first insert block, respectively. The first slot and the first insert block are detachably connected, which allows the number of the second support block and its connecting parts in the scraper assembly to be flexibly adjusted according to the width of the electroplating tank body. This ensures that the length of the scraper assembly, the first L-shaped column and the second L-shaped column combined can adapt to the inner width of the electroplating tank body. Each side of the first support block and the second support block is provided with an installation groove, and the connecting block is detachably connected to the installation groove, which facilitates the installation and maintenance of the connecting block.

[0008] As a further provision of the above scheme, a second insert and a second slot are respectively provided on one side of the lower end of the first L-shaped column and the second L-shaped column. The second slot and the second insert are detachably connected to the first insert and the first slot at both ends of the scraper assembly, which facilitates the connection of the two L-shaped columns and the scraper assembly. A fourth scraper with the same cross-section as the first scraper is connected below each of the two third scrapers. Two fifth scrapers with the same cross-section as the second scraper are symmetrically connected below each of the two fourth scrapers. This allows the length of the fourth scraper combined with the first scraper and the length of the fifth scraper combined with the second scraper to be adapted to the inner width of the electroplating tank body.

[0009] As a further feature of the above scheme, the upper ends of the first L-shaped column and the second L-shaped column are detachably connected to top plates. The two top plates are connected to connecting shafts on opposite sides. Limiting plates are provided through the outer side of the connecting shafts and slide in cooperation with the limiting plates, allowing the distance between the limiting plates and the top plates to be adjusted according to the wall thickness of the electroplating tank body. A retaining ring is provided on the side of the limiting plate away from the top plate, and the retaining ring slides in cooperation with the connecting shaft to restrict the position of the limiting plate. The sides of the two limiting plates that are close to each other slide in cooperation with the two outer sidewalls of the electroplating tank body, thereby restricting the movement direction of the cleaning mechanism.

[0010] As a further feature of the above solution, the upper end of the mounting plate is provided with a through hole, and the telescopic end of the telescopic rod is connected to an insert rod. The insert rod passes through the inside of the through hole and is slidably connected to the through hole. A nut is threaded on the outside of the insert rod to facilitate the connection and separation of the insert rod from the mounting plate. The telescopic rod is connected to a terminal device via an electrical signal to facilitate the user to control the extension and retraction of the telescopic rod.

[0011] As a further feature of the above solution, the slot engages with one end of the electroplating tank body, which can initially restrict the position of the power mechanism. The power mechanism is installed above one end of the electroplating tank body. A threaded rod is threaded through the threaded hole and threadedly connected to the threaded rod. A pressure block is connected to the lower end of the threaded rod. The side of the pressure block away from the threaded rod is in contact with the upper surface of the electroplating tank body, which can further restrict the position of the bracket and the telescopic rod, so that the telescopic rod remains stable during use.

[0012] As a further feature of the above solution, the two limiting plates are respectively attached to the two sides of the U-shaped plate, so that when the cleaning mechanism is idle, the cleaning mechanism can be pulled out from the inside of the electroplating tank body and placed inside the U-shaped plate, so as to avoid the cleaning mechanism occupying the space inside the electroplating tank.

[0013] As a further feature of the above solution, the slot engages with the side of the U-shaped plate away from the electroplating tank body, and the side of the pressure block away from the threaded rod is attached to the upper surface of the U-shaped plate. This allows the power mechanism connected to the cleaning mechanism to be placed above the U-shaped plate when the power mechanism is idle, so that the user can access it when cleaning the electroplating tank body.

[0014] The present invention has the following beneficial effects during use:

[0015] The combination of the first support block and multiple second support blocks in the scraper assembly allows for flexible adjustment of the number of second support blocks according to the inner width of the electroplating tank body. This enables the combined length of the scraper assembly, the first L-shaped column, and the second L-shaped column to adapt to the inner width of the electroplating tank body, improving the practicality of the cleaning mechanism. The combination of the five scrapers in the cleaning mechanism with the telescopic rod in the power mechanism allows for simultaneous cleaning of both sides of the inner wall of the electroplating tank body and the bottom of the electroplating tank body, increasing the workload of cleaning the inner wall of the electroplating tank body.

[0016] The use of two limiting plates can restrict the movement direction of the cleaning mechanism, ensuring that the cleaning mechanism moves smoothly inside the electroplating tank body. The use of U-shaped plates can provide support for the idle cleaning mechanism and power mechanism, regulate the position of the two mechanisms, facilitate user access, prevent the two mechanisms from occupying the internal space of the electroplating tank body during metal electroplating operations, prevent electroplating liquid dripping from the metal from falling onto the cleaning mechanism and power mechanism, and reduce the workload of users in cleaning the above mechanisms.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-7 This application will be described in detail with reference to the embodiments.

[0028] An embodiment discloses an electroplating tank for metal electroplating, including an electroplating tank body 1. A drain pipe 11 is connected to the lower end of one end of the electroplating tank body 1, and a valve 12 is provided at one end of the drain pipe 11. A U-shaped plate 13 is connected to the upper end of the electroplating tank body 1 away from the drain pipe 11. A cleaning mechanism 2 is provided at the end of the electroplating tank body 1 near the U-shaped plate 13. A power mechanism 3 is provided on one side of the cleaning mechanism 2. The cleaning mechanism 2 includes a scraper assembly 21. The scraper assembly 21 includes a first support block 211. A mounting plate 212 is connected to the upper part of the first support block 211. Multiple second support blocks 213 arranged in a linear array are provided at both ends of the first support block 211. The inner sides of the second support block 213 and the first support block 211 are both connected to a connecting block 214. A first scraper 215 is provided below the connecting block 214. Two second scrapers 216 are symmetrically connected below the first scraper 215. A first L-shaped column 22 and a second L-shaped column 24 are respectively provided at both ends of the scraper assembly 21. A third scraper 221 is provided on the side of the second L-shaped column 24 and the first L-shaped column 22 that are far apart from each other. The power mechanism 3 includes a telescopic rod 31 and a bracket 32. A bracket 32 ​​is provided on the outer side of the telescopic rod 31. A slot 321 is provided on both sides of one end of the bracket 32. A threaded hole 322 is provided at the bottom of the slot 321.

[0029] like Figure 2 and Figure 3 As shown, each end of the first support block 211 and the second support block 213 is provided with a first slot 2111 and a first insert 2112, respectively. The first slot 2111 and the first insert 2112 are detachably connected. The number of the second support block 213 and its connecting parts in the scraper assembly 21 can be flexibly adjusted according to the width of the electroplating tank body 1, so that the length of the scraper assembly 21, the first L-shaped column 22 and the second L-shaped column 24 combined can adapt to the inner width of the electroplating tank body 1. The first support block 211 and the second support block 213 are each provided with an installation groove 2113 on one side. The connecting block 214 is detachably connected to the installation groove 2113, which facilitates the installation and maintenance of the connecting block 214.

[0030] like Figure 2 , Figure 4 and Figure 5As shown, the lower ends of the first L-shaped column 22 and the second L-shaped column 24 are respectively provided with a second insert 222 and a second slot 241. The second slot 241 and the second insert 222 are detachably connected to the first insert 2112 and the first slot 2111 at both ends of the scraper assembly 21, which facilitates the connection of the two L-shaped columns with the scraper assembly 21. The lower part of each of the two third scrapers 221 is connected to a fourth scraper 23 with the same cross section as the first scraper 215. The lower part of each of the two fourth scrapers 23 is symmetrically connected to two fifth scrapers 231 with the same cross section as the second scraper 216. This allows the length of the fourth scraper 23 combined with the first scraper 215 and the length of the fifth scraper 231 combined with the second scraper 216 to be adapted to the inner width of the electroplating tank body 1.

[0031] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the upper ends of the first L-shaped column 22 and the second L-shaped column 24 are detachably connected to a top plate 25. The two top plates 25 are connected to a connecting shaft 251 on the side away from each other. A limiting plate 26 is provided through the outer side of the connecting shaft 251 and slides with the limiting plate 26. The distance between the limiting plate 26 and the top plate 25 can be adjusted according to the wall thickness of the electroplating tank body 1. A retaining ring 252 is provided on the side of the limiting plate 26 away from the top plate 25. The retaining ring 252 slides with the connecting shaft 251 and can limit the position of the limiting plate 26. The sides of the two limiting plates 26 that are close to each other slide with the two outer sidewalls of the electroplating tank body 1, which can limit the movement direction of the cleaning mechanism 2.

[0032] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the upper end of the mounting plate 212 is provided with a through hole 2121. The telescopic end of the telescopic rod 31 is connected to a plug rod 311. The plug rod 311 passes through the interior of the through hole 2121 and is slidably connected to the through hole 2121. A nut 312 is threadedly connected to the outside of the plug rod 311 to facilitate the connection and separation of the plug rod 311 from the mounting plate 212. The telescopic rod 31 is connected to the terminal device via an electrical signal, which facilitates the user to control the extension and retraction of the telescopic rod 31.

[0033] like Figure 1 and Figure 6As shown, the slot 321 engages with one end of the electroplating tank body 1, which can initially restrict the position of the power mechanism 3. The power mechanism 3 is installed above one end of the electroplating tank body 1. A threaded rod 33 is threaded through the inside of the threaded hole 322 and is threadedly connected to the threaded rod 33. A pressure block 331 is connected to the lower end of the threaded rod 33. The side of the pressure block 331 away from the threaded rod 33 is in contact with the upper surface of the electroplating tank body 1, which can further restrict the position of the bracket 32 ​​and the telescopic rod 31, so that the telescopic rod 31 remains stable during use.

[0034] like Figure 7 As shown, the two limiting plates 26 are close to each other on one side and respectively abut against the two sides of the U-shaped plate 13. When the cleaning mechanism 2 is idle, it can be pulled out from the inside of the electroplating tank body 1 and placed inside the U-shaped plate 13 to prevent the cleaning mechanism 2 from occupying the space inside the electroplating tank.

[0035] As shown in Figure 7, the slot 321 engages with the side of the U-shaped plate 13 away from the electroplating tank body 1, and the pressure block 331 is attached to the upper surface of the U-shaped plate 13 on the side away from the threaded rod 33. When the power mechanism 3 is idle, the power mechanism 3 connected to the cleaning mechanism 2 can be placed above the U-shaped plate 13 so that the user can access it when cleaning the electroplating tank body 1.

[0036] The electroplating tank for metal electroplating disclosed in this embodiment, before cleaning, opens valve 12 to drain the residual electroplating solution from drain pipe 11. An appropriate number of second support blocks 213 are selected according to the width of the electroplating tank body 1. According to the design, the first slots 2111 and first inserts 2112 at both ends of the first support block 211 are connected to the first inserts 2112 and first slots 2111 at one end of each of the two second support blocks 213, respectively. The second support blocks 213 are then installed at the ends of the second support blocks 213 furthest from the first support blocks 211, until the second support blocks 213 are fully installed. Multiple connections are then established. Block 214 is sequentially installed in the mounting grooves 2113 inside the first support block 211 and multiple second support blocks 213 to form a complete scraper assembly 21. The two ends of the scraper assembly 21 are the first insert block 2112 and the first slot 2111, respectively. The first L-shaped column 22 and the second L-shaped column 24 are respectively installed at the two ends of the scraper assembly 21, so that the second insert block 222 is connected to the first slot 2111, and the second slot 241 is connected to the first slot 2111. The first scraper 215 is aligned with the fourth scraper 23, and the second scraper 216 is aligned with the fifth scraper 231. After the connection is completed, the cleaning mechanism 2 is assembled.

[0037] Grasp the upper end of the mounting plate 212 and place the cleaning mechanism 2 inside the electroplating tank body 1. During placement, ensure that the first scraper 215 and the fourth scraper 23 are in contact with the inner wall of the electroplating tank body 1 away from the drain pipe 11. After scraping off the residual electroplating liquid on the inner wall of the electroplating tank body 1 away from the drain pipe 11, push the cleaning mechanism 2 to the inner side of the electroplating tank body 1, so that the second scraper 216 and the fifth scraper 231 contact the bottom of the electroplating tank body 1. Adjust the position of the retaining ring 252 and the limiting plate 26 on the connecting shaft 251, so that the side of the two limiting plates 26 that is close to each other is in contact with the two sides of the electroplating tank body 1. Secure the two slots 321 at one end of the bracket 32 ​​into the electroplating tank body 1 away from the drain pipe 11. Insert the insertion rod 311 at one end of the telescopic rod 31 into the through hole 2121, and screw the nut 312 to the outside of the insertion rod 311 to restrict the position of the insertion rod 311. Rotate the two threaded rods 33 in sequence to adjust the distance between the pressure block 331 and the electroplating tank body 1 so that the pressure block 331 fits into the electroplating tank body 1. Return the bracket 32 ​​and the telescopic rod 31 to the center to keep them stable. Use the terminal device to control the extension of the telescopic rod 31, which drives the cleaning mechanism 2 to move towards the drain pipe 11 on the inside of the electroplating tank body 1. During the movement, the second scraper 216 and the fifth scraper 231 can clean the bottom inside of the electroplating tank body 1, and the two third scrapers 221 can clean the two side walls of the electroplating tank body 1 respectively.

[0038] When the telescopic rod 31 pushes the cleaning mechanism 2 to the end of the electroplating tank body 1 near the drain pipe 11, unscrew the nut 312 from the outside of the insertion rod 311, use the terminal device to control the telescopic rod 31 to retract, pull the insertion rod 311 out of the through hole 2121, hold the mounting plate 212 and pull the cleaning mechanism 2 out from the inside of the electroplating tank body 1, press down the cleaning mechanism 2 after the side of the second scraper 216 and the fourth scraper 23 away from the telescopic rod 31 is attached to the inner wall of the electroplating tank body 1 near the drain pipe 11, scrape off the residual electroplating liquid on the inner wall, and when the cleaning mechanism 2 is pushed to the bottom of the electroplating tank body 1, the electroplating tank body 1 is cleaned. Pull the cleaning mechanism 2 out from the inside of the electroplating tank body 1 and place it inside the U-shaped plate 13. After separating the slot 321 from the electroplating tank body 1, place it on the end of the U-shaped plate 13 away from the electroplating tank body 1.

[0039] The combination of five scrapers in the cleaning mechanism 2 can scrape the residual electroplating liquid on one end of the vertical surface of the electroplating tank body 1 to the bottom of the electroplating tank body 1 during the process of placing the cleaning mechanism 2 inside the electroplating tank body 1. As the telescopic rod 31 in the power mechanism 3 extends and retracts, it can drive the cleaning mechanism 2 to move inside the electroplating tank body 1, so that the second scraper 216 and the fifth scraper 231 scrape the electroplating liquid at the bottom of the electroplating tank body 1 to one end of the drain pipe 11, and the two third scrapers 221 scrape off the residual electroplating liquid on both sides of the inner wall of the electroplating tank body 1, thus completing the cleaning of the inner wall of the electroplating tank body 1.

[0040] The components disclosed in this utility model for an electroplating tank for metal electroplating, including the electroplating tank body 1, drain pipe 11, valve 12, U-shaped plate 13, mounting plate 212, connecting block 214, first scraper 215, second scraper 216, first L-shaped column 22, third scraper 221, fourth scraper 23, fifth scraper 231, second L-shaped column 24, top plate 25, connecting shaft 251, retaining ring 252, limiting plate 26, telescopic rod 31, insertion rod 311, nut 312, bracket 32, threaded rod 33, and pressure block 331, are all general standard parts or parts known to those skilled in the art.
