Description

Technical Field

[0001] This utility model relates to the field of electroplating technology, and in particular to a vertical single and double nozzle spot plating device. Background Technology

[0002] Spot plating (also known as selective electroplating or localized electroplating) is a surface treatment technology that uses electrolysis to deposit a metal layer on the surface of a workpiece. It is widely used in electronics, automotive, aerospace, and other fields to improve the corrosion resistance, conductivity, and aesthetics of workpieces. Unlike traditional overall electroplating, spot plating allows for precise control of the location and thickness of the plating layer, making it suitable for workpieces with specific performance requirements in certain areas, such as repairing worn parts, enhancing local conductivity, or improving corrosion resistance. Spot plating technology has wide applications in aerospace, electronics manufacturing, and the automotive industry.

[0003] In traditional spot plating processes, a protective solution is indeed needed after the plating step to prevent oxidation or contamination of the coating. However, the traditional method involves removing the workpiece from the plating equipment after plating and transferring it to a separate area for applying the protective solution. This method has significant limitations. Firstly, during the transfer, the coating comes into contact with oxygen, moisture, and contaminants such as dust and impurities in the workshop, increasing the risk of oxidation or contamination. Secondly, separate operations increase production costs and reduce efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a vertical single and dual nozzle spot plating device. This device sprays electroplating solution and protective solution respectively through two nozzles. The two nozzles can be switched, and the water tank below the nozzle is switched simultaneously when switching nozzles.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a vertical single and double nozzle spot plating equipment, including an operating table, a nozzle switching component on the operating table, and a water tank switching component inside the operating table;

[0006] The nozzle switching assembly includes a switching base plate with two slide rails, each slide rail having a slider, and the slider having a first nozzle and a second nozzle. A first chain is provided on the switching base plate, and connecting plates are provided on the two sliders. The two connecting plates are respectively connected to the left half and the right half of the first chain.

[0007] The water tank switching assembly includes a first track and a second track. A first slide plate is installed on the first track, and a first water tank is installed on the first slide plate. A second slide plate is provided on the second track. A sleeve is provided on the second slide plate, and a tube is installed inside the sleeve. A second water tank is installed at the top of the tube. The water tank switching assembly includes a second chain. The first slide plate and the second slide plate are respectively installed on the lower half and upper half of the second chain. A motor is connected to the second chain. A third chain connects the second chain and the first chain. The water tank switching and the nozzle switching are performed synchronously.

[0008] Furthermore, the water tank switching assembly includes a switching base plate, with first support plates at both ends of the switching base plate, a first track installed on the top of the first support plates, and two second support plates in the middle of the switching base plate, the second support plates being lower than the first support plates, and a second track being installed on the top of the second support plates.

[0009] Furthermore, several drive shafts are horizontally installed on the inner side of the first support plate, a second sprocket is installed on the drive shaft, a second chain is installed between the drive shafts, a motor is connected to one of the drive shafts, a third master sprocket is installed on the motor output shaft, a third slave sprocket is installed on the rotating shaft, and the third master sprocket and the third slave sprocket are connected.

[0010] Furthermore, the first sliding plate is provided with a first docking plate, which is connected to the upper half of the second chain, and the second sliding plate is provided with a second docking plate on its side, which is connected to the lower half of the second chain.

[0011] Furthermore, the second slide plate has a square hole in the middle, and a roller bracket is provided below the second water tank. The roller bracket passes through the square hole in the middle of the second slide plate, and a rotating wheel is installed at the lower end of the roller bracket. A V-shaped plate is installed in the middle of the switching base plate, and a V-shaped groove is provided on the V-shaped plate, with the rotating wheel locked in the V-shaped groove.

[0012] Furthermore, the operating table is provided with a positioning component, which includes a positioning bracket, mounting plates at both ends of the positioning bracket, a placement plate connected between the mounting plates, a straight groove on the mounting plate, a moving block installed in the straight groove, an electric push rod installed on the moving block, and the top of the electric push rod engaging with the positioning plate.

[0013] Furthermore, one side of the slide rail is provided with an arc-shaped groove, and a roller is installed on one side of the slider. The roller is located in the arc-shaped groove. The other side of the slide rail is provided with a long groove. A connecting plate is provided on the slider. The connecting plate passes through the long groove and is connected to the first chain. A movable plate is slidably connected on the slider. The first nozzle and the second nozzle are respectively installed on the two movable plates.

[0014] Furthermore, the switching base plate has two rotating shafts at its upper and lower ends, with a first sprocket mounted on the rotating shafts and a first chain installed between the two first sprockets.

[0015] Furthermore, a protective shell is installed on the outside of the operating table, and an electroplating solution tank and a protective liquid tank are installed on the top of the dustproof shell. The electroplating solution tank is connected to the first nozzle through a hose, and the protective liquid tank is connected to the second nozzle through a hose.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: The workpiece is placed on the placement plate, and the positioning plate is driven by the electric push rod to position the workpiece. After positioning, the third chain is moved by the motor, which in turn moves the first chain, causing the first nozzle to move downwards to directly above the workpiece. At the same time, the motor drives the second chain to move the first water tank below the first nozzle, and the electrolyte is output to the workpiece through the first nozzle. After spot plating is completed, the motor is controlled to rotate in the opposite direction, driving the third chain to move, which in turn drives the first chain to move. Since the left half of the chain moves in the opposite direction to the right half of the chain, while the first nozzle moves upwards, the second nozzle moves downwards to directly above the workpiece. Similarly, the motor drives the second chain to move, and the second water tank switches to directly below the second nozzle, and the protective liquid is output to the workpiece through the second nozzle.

[0017] This invention allows for the switching of a second nozzle to output a protective liquid after the first nozzle has finished dispensing the electroplating solution, thus protecting the spot-plated product. Furthermore, the switching between the first and second nozzles simultaneously switches the water tank below each nozzle. This prevents the electroplating solution and protective liquid from falling into the same tank and becoming unrecoverable. This invention improves plating quality and production efficiency while reducing costs. Attached Figure Description

Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of the present application.

[0028] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to an electrical connection; they can refer to a hydraulic connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] See Figure 1-8 As shown, a vertical single / dual-nozzle spot plating device includes an operating table 101. A positioning component is mounted on the operating table 101, and the workpiece is placed within the positioning component, which stabilizes the workpiece during the spot plating process. A spot plating component is located on one side of the positioning component, and the spot plating component includes two nozzles. The two nozzles are used to output electroplating solution and protective solution respectively to meet the different needs of the workpiece. A nozzle switching component is mounted on the operating table 101, and the two nozzles are installed on the nozzle switching component, which can switch between the two nozzles. A water tank switching component is located inside the operating table 101, which can switch between two water tanks, preventing the electroplating solution and protective solution from falling into the same water tank and becoming unrecoverable. The water tank switching and nozzle switching are performed synchronously.

[0030] The aforementioned control panel 101 is rectangular in shape, and a protective outer shell 102 is installed on the outside of the control panel 101. The positioning assembly is mounted on the operating table 101 and located within the protective housing 102. The positioning assembly includes a rectangular positioning bracket 201 with mounting plates 202 at both ends. The mounting plates 202 are symmetrically distributed along the central axis of the positioning bracket 201. A placement plate 203 connects between the two mounting plates 202, located below the positioning bracket 201. The workpiece to be processed is placed on the placement plate 203. Both mounting plates 202 have straight grooves 204, and a moving block 205 is installed within each groove. The moving block 205 can move along the groove and is bolted to the mounting plate 202. An electric actuator 206 is mounted on the moving block 205. The top of the output shaft of the electric actuator 206 connects to the positioning plate 207. The electric actuator 206 simultaneously moves the positioning plate 207 towards the center, thus positioning the workpiece on the placement plate 203. After positioning the workpiece, a spot plating operation can be performed on it using a spot plating assembly.

[0031] The spot plating assembly includes a power supply 301, which is located inside the operating table 101. The positive terminal of the power supply 301 is connected to the plating head, and the negative terminal is connected to the workpiece to be plated. An electroplating solution tank 302 and a protective solution tank 303 are installed on the top of the dustproof housing. The electroplating solution tank 302 and the protective solution tank 303 are used to output the electroplating solution and the protective solution, respectively. The electroplating solution tank 302 is connected to a first nozzle 304 via a hose, and the protective solution tank 303 is connected to a second nozzle 305 via a hose. The first nozzle 304 and the second nozzle 305 are mounted on a switching assembly. When spot plating is required, the first nozzle 304 moves downwards to directly above the workpiece via the nozzle switching assembly, providing the electroplating solution to the workpiece. After spot plating is completed, the second nozzle 305 of the nozzle switching assembly switches and moves to directly above the workpiece, outputting the protective solution to the plated workpiece.

[0032] The nozzle switching assembly includes a support column with a rectangular switching base plate 306 mounted on it. The switching base plate 306 is perpendicular to the operating table 101. Two slide rails 307 are symmetrically arranged along the central axis of the switching base plate 306. Each slide rail 307 has a slider 308 mounted on it, and a moving plate 309 is mounted on each slider 308. The first nozzle 304 and the second nozzle 305 are respectively mounted on the two moving plates 309. Two rotating shafts 310 are located at the upper and lower ends of the back of the moving base plate. A first sprocket 311 is mounted on the rotating shaft 310, and a first chain 312 connects the two sprockets. Two long grooves 316 are provided on the moving base plate, located inside the two slide rails 307. Connecting plates 315 are provided inside the two sliders 308, and the two connecting plates 315 pass through the long grooves 316 and are respectively connected to the left and right halves of the first chain 312.

[0033] To ensure that the first nozzle 304 and the second nozzle 305 are directly facing the workpiece, an arc-shaped groove 313 is provided next to each of the two slide rails 307. The arc-shaped groove 313 is located on the outside of the slide rail 307. A roller 314 is installed on one side of the slider 308, located within the arc-shaped groove 313 and movable along the arc-shaped groove 313. The aforementioned movable base plate has a corner and is S-shaped overall. The first nozzle 304 and the second nozzle 305 are both installed on the top of the movable base plate. The aforementioned slider 308 is slidably connected to the movable plate 309, and the movable plate 309 can slide left and right on the slider 308.

[0034] It should be noted that when the first chain 312 rotates, its left and right halves move in opposite directions. At this time, the slider 308, connected to the first chain 312 via the connecting plate 315, moves in opposite directions, and the slider moves along the arcuate groove 313. When the first nozzle 304 moves downwards, the second nozzle 305 moves upwards. Furthermore, when it reaches the peak of the arcuate groove 313, the moving plate 309 drives the nozzle to slide towards the edge of the switching base plate 306, causing the first nozzle 304 and the second nozzle 305 to move out of position in the middle. Simultaneously with the switching of the first nozzle 304 and the second nozzle 305, the two water tanks mounted on the operating platform 101 also switch synchronously on the water tank switching assembly.

[0035] Specifically, a rectangular switching base plate 401 is provided inside the operating table 101. The switching base plate 401 is parallel to the operating table 101 and located inside the operating table. First support plates 402 are vertically connected to both ends of the switching base plate 401. Several drive shafts are horizontally mounted inside the first support plates 402. Second sprockets 404 are connected between the drive shafts, and second chains 403 are connected between the second sprockets 404. A motor 405 is connected to the drive shaft. A third master sprocket 406 is mounted on the output shaft of the motor 405, and a third slave sprocket 407 is mounted on the rotating shaft 310. A third chain connects the third master sprocket 406 and the third slave sprocket 407. While the motor 405 drives the second chain 403 to move, it also drives the first chain 312 to move via the third chain.

[0036] A first track 409 is provided at the top of the first support plate 402, and a first slide plate 410 is installed on the first track 409. A first docking plate 412 is provided on the inner side of the first slide plate 410, and the first docking plate 412 is connected to the upper half of the second chain 403. A first water tank 411 is installed on the first slide plate 410. Two second support plates 413 are vertically installed in the middle of the switching base plate 401. The second support plates 413 are parallel to the first support plate 402 and are lower than the first support plate 402. A second track 423 is provided at the top of the second support plate 413, and a second slide plate 414 is installed on the second track 423. A second docking plate 415 is provided on the side of the second slide plate 414, and the second docking plate 415 is connected to the lower half of the second chain 403.

[0037] Sleeves 416 are provided at the four corners of the second slide plate 414. A sleeve 417 is installed inside the sleeve 416. The sleeve 417 can move vertically within the sleeve 416. A second water tank 418 is installed at the top of the sleeve 417. The second water tank 418 is parallel to the second slide plate 414. A square hole is provided in the middle of the second slide plate 414. A roller bracket 419 is provided below the second water tank 418. The roller bracket 419 passes through the square hole in the middle of the second slide plate 414. A rotating wheel 420 is installed at the lower end of the roller bracket 419. A V-shaped plate 421 is vertically installed in the middle of the switching base plate 401. A V-shaped groove 422 is provided on the V-shaped plate 421. The valley point of the V-shaped groove 422 is located at the center of the switching base plate 401. The rotating wheel 420 is locked in the V-shaped groove 422 and can move along the V-shaped groove 422.

[0038] It should be noted that the first water tank 411 and the second water tank 418 are located on the same horizontal line, and the edges of the first water tank 411 and the second water tank 418 are flush with the surface of the operating table 101. When the motor 405 drives the second chain 403 to move, the upper half of the chain moves in opposite directions to the lower half of the chain. When the first water tank 411 moves to the left along the first slide rail 307, the second slide rail 307 moves to the right along the second slide rail 307, and the rotating wheel 420 gradually moves down along the inclined surface of the V-shaped groove 422, and drives the second water tank 418 down through the support roller frame 419. When the first water tank 411 and the second water tank 418 move to the middle position, the rotating wheel 420 moves to the valley point of the V-shaped groove 422. The second water tank 418 passes under the first water tank 411. As the second chain 403 continues to move, the second water tank 418 gradually moves upward along the inclined surface of the V-shaped groove 422 under the drive of the rotating wheel 420, and finally is on the same horizontal line as the first water tank 411, completing the switching of the water tank.
