Description

Technical Field

[0001] The present invention relates to the technical field of electroplating equipment, and in particular to an electroplating equipment. Background Art

[0002] Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. It is a process that uses electrolysis to attach a layer of metal film to the surface of metal or other material parts, thereby preventing metal oxidation (such as rust), improving wear resistance, conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and enhancing aesthetics. When electroplating automobile metal tubular parts, the pipes are first fixed on the electroplating racks, and then the electroplating racks are moved to immerse the pipes in the electroplating solution. Since the electroplating solution and pipes in the electroplating tank are both in a static state, the electroplating solution is prone to local concentrations that are too high or too low, resulting in uneven distribution of metal ions, thereby reducing the electroplating effect; In order to improve the electroplating effect, many current production processes install air stirring devices in the electroplating tank. However, this process cannot avoid the reaction between the electroplated device and the electroplating solution and oxygen in the air, which can easily cause problems such as uneven electroplating layer and a small amount of impurities. At the same time, the use of gas stirring alone consumes a lot of power and has low stirring efficiency. Some production processes also use a stirring paddle to stir the plating solution. Although it can drive the plating solution to mix, the stirring paddle can only stir the surrounding plating solution, and the stirring range is small. It is impossible to stir the plating solution comprehensively, resulting in uneven distribution of metal ions in the plating solution and failure to guarantee the electroplating effect.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are partial embodiments of the present invention, rather than all embodiments.

When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centered component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centered component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0021] like Figures 1 to 13 As shown, the present invention provides an electroplating device, comprising: a machine platform 1; an electroplating tank 2 fixedly mounted on the machine platform 1; a moving mechanism 3 for driving a pipe to move in the electroplating tank 2; and a stirring mechanism 4 for stirring the electroplating solution in the electroplating tank 2.

[0022] The stirring mechanism 4 includes: an annular plate 41, a movable plate 43, and a stirring blade 44 for stirring the electroplating liquid in the electroplating tank 2; a guide groove 42 for guiding the swing path of the movable plate 43, and the guide groove 42 is a corrugated groove with a uniform waveform; a driving component 46 for driving the annular plate 41, the movable plate 43, and the stirring blade 44 to stir the electroplating liquid; the annular plate 41 is movably installed in the electroplating tank 2, and the movable plate 43 is rotatably installed in the electroplating tank 2. There are multiple movable plates 43, and they are evenly distributed in the electroplating tank 2 in a ring shape. A movable rod 45 is fixedly installed on the movable plate 43, and the guide groove 42 is opened on the inner side of the annular plate 41 along the moving direction of the annular plate 41, and the movable rod 45 is slidably installed in the guide groove 42.

[0023] When the driving assembly 46 is started, the driving assembly 46 drives the annular plate 41 to move up and down, and drives the stirring blade 44 to rotate. When the annular plate 41 moves, the movable rod 45 slides along the path of the guide groove 42. Since the guide groove 42 is a wave-shaped groove with a uniform waveform, the movable plate 43 swings along the path of the guide groove 42. The annular plate 41 moves up and down reciprocatingly, so as to stir the electroplating solution along the depth direction of the electroplating tank 2; The movable plate 43 swings so as to stir the electroplating solution in the horizontal direction of the electroplating tank 2; The stirring blade 44 rotates to stir the electroplating solution along the circumference of the electroplating tank 2; By setting the annular plate 41, the movable plate 43 and the stirring blade 44, the plating solution in the plating tank 2 can be stirred from different directions to ensure that the metal ions in the plating solution are evenly distributed in the vertical direction and the metal ions in the plating solution are evenly mixed in the horizontal direction, thereby ensuring the quality and stability of the electroplating layer and improving the electroplating effect.

[0024] The driving assembly 46 includes: a fixed box 461 fixedly mounted on the machine 1; a threaded rod 462 rotatably mounted on the fixed box 461; a power source 463 for driving the threaded rod 462 to rotate, and the power source 463 is fixedly mounted on the fixed box 461; a sleeve 464 fixedly sleeved on the threaded rod 462; a moving frame 465 slidably mounted on the sleeve 464, a limited opening is provided on the fixed box 461, and the moving frame 465 passes through the inner cavity of the limited opening. By setting the limited opening, the moving frame 465 can be limited, thereby improving the stability of the moving frame 465 during movement; a limiting rod 466 for limiting the moving frame 465, and a limiting rod 466 for limiting the moving frame 465. The positioning rod 466 passes through the side wall of the movable frame 465, and both ends of the limiting rod 466 are fixedly installed in the fixed box 461. Two limiting rods 466 are symmetrically arranged, thereby providing a uniform limiting effect on the movable frame 465, and further improving the stability of the movable frame 465 during movement; a reciprocating groove 467 is opened on the sleeve 464, and the reciprocating groove 467 is composed of two U-shaped grooves in opposite directions and interconnected with each other; a rolling member 468 rollingly installed in the reciprocating groove 467; and a linkage unit 469 that drives the stirring blade 44 to rotate; the annular plate 41 is fixedly connected to the movable frame 465; the rolling member 468 is rotatably connected to the movable frame 465.

[0025] The starting power source 463 drives the threaded rod 462 to rotate, and the threaded rod 462 drives the sleeve 464 to rotate, so that the rolling element 468 moves along the path of the reciprocating groove 467. Since the reciprocating groove 467 is composed of two U-shaped grooves in opposite directions and interconnected, it can drive the movable frame 465 to move up and down along the axial direction of the sleeve 464. The movable frame 465 drives the annular plate 41 to move up and down, so that the annular plate 41 stirs the plating solution along the depth direction of the plating tank 2, thereby making the plating solution fully mixed in the depth direction, and can stir the plating solution from the bottom of the tank to the surface of the tank, ensuring that the metal ions in the plating solution are evenly distributed in the vertical direction, avoiding the problem of inconsistent plating quality due to concentration differences between the bottom and the surface of the tank.

[0026] When the annular plate 41 moves up and down reciprocatingly, the movable rod 45 slides along the path of the guide groove 42. Since the guide groove 42 is a uniformly corrugated groove with a certain depth and width, the diameter of the movable rod 45 is smaller than the width of the guide groove 42, so that the movable rod 45 can slide along the inner cavity of the guide groove 42 and shake at the same time, thereby causing the movable plate 43 to swing.

[0027] Since the multiple groups of movable plates 43 synchronously swing back and forth in the horizontal direction of the electroplating tank 2, the plating solution can be stirred in the horizontal direction of the electroplating tank 2, which helps to achieve uniform distribution of the plating solution in the electroplating tank 2, so that the metal ions in the plating solution are evenly mixed in the horizontal direction, avoiding the problem of local excessive or low concentration, so that the metal ions in the plating solution of the entire electroplating tank 2 are evenly distributed, thereby ensuring the quality and stability of the electroplating layer.

[0028] It is to be added here that the power source 463 is preferably: a motor; the rolling element 468 is preferably: a bull's eye ball.

[0029] The linkage unit 469 includes: a rotating tube 4691 rotatably mounted on the machine 1 and the electroplating tank 2; a driven pulley 4692 fixedly mounted on the rotating tube 4691; a driving pulley 4693 fixedly mounted on the threaded rod 462; a linkage belt 4694 transmission-connected to the driving pulley 4693 and the driven pulley 4692; and a stirring blade 44 fixedly mounted on the rotating tube 4691.

[0030] When the threaded rod 462 rotates, the driving pulley 4693 is driven to rotate, and the driving pulley 4693 drives the driven pulley 4692 to rotate through the interlocking belt 4694, thereby driving the rotating tube 4691 to rotate, and the rotating tube 4691 drives the stirring blade 44 to rotate, so that the plating liquid can be stirred along the circumference of the plating tank 2 to avoid precipitation of the plating liquid, so that the metal ions in the plating liquid of the entire plating tank 2 are evenly distributed, further ensuring the quality and stability of the electroplating layer.

[0031] It should be added here that, compared with the stirring by rotation of the stirring paddle and the stirring by air, the stirring mechanism 4 in the present invention stirs the plating liquid synchronously along the depth direction, the horizontal direction, and the circumferential direction of the electroplating tank 2, which can not only mix the plating liquid in the depth direction, but also stir the plating liquid from the bottom of the tank to the tank surface, ensuring that the metal ions in the plating liquid are evenly distributed in the vertical direction, thus avoiding the problem of inconsistent electroplating quality due to concentration differences between the bottom and the surface of the tank, and can also make the metal ions in the plating liquid be evenly mixed in the horizontal direction, thus avoiding the problem of local excessive or low concentration, so that the metal ions in the plating liquid of the entire electroplating tank 2 are evenly distributed, thereby ensuring the quality and stability of the electroplating layer, achieving a large stirring range, high electroplating efficiency, and good electroplating effect, thereby preparing for the pipe fittings to enter the electroplating tank 2 for electroplating.

[0032] The moving mechanism 3 includes: a movable frame 31 threadedly connected to the threaded rod 462, a limiting rod 466 penetrating the side wall of the movable frame 31 and limiting the movable frame 31, thereby improving the stability of the movable frame 31 during movement; a clamping assembly 32 for clamping and fixing the pipe fitting; a revolution assembly 33 for driving the pipe fitting to rotate along the circumference of the electroplating tank 2; a lifting assembly 34 for driving the pipe fitting to rise and fall along the axial direction of the electroplating tank 2; and a rotation assembly 35 for driving the pipe fitting to rotate.

[0033] The pipe to be electroplated is clamped and fixed by the clamping assembly 32. At this time, the power source 463 is started to drive the threaded rod 462 to rotate, and the threaded rod 462 drives the movable frame 31 to move downward, thereby driving the pipe to move downward into the electroplating tank 2 for electroplating.

[0034] It can be seen that when the power source 463 is started to drive the threaded rod 462 to rotate, on the one hand, it can drive the pipe fittings to move into the electroplating tank 2, and on the other hand, it can synchronously drive the annular plate 41, the movable plate 43, and the stirring blade 44 to stir the electroplating liquid, thereby realizing the stirring of the electroplating liquid before the electroplating of the pipe fittings, so that the metal ions are evenly distributed in the entire solution, which can not only ensure that the metal layer deposited on the surface of the pipe fittings is uniform and dense, and improve its performance and appearance quality, but also increase the chance of metal ions contacting the pipe fittings, accelerate the reaction rate, and thus improve the electroplating quality and efficiency of the pipe fittings.

[0035] When the electroplating of the pipe is completed, the power source 463 is started to rotate in the reverse direction, thereby driving the pipe to be removed from the electroplating tank 2.

[0036] The clamping assembly 32 includes: an installation box 321; a bidirectional screw 322 rotatably installed on the installation box 321 and the movable box 334; a power source 323 for driving the bidirectional screw 322 to rotate; a movable seat 324 threadedly connected to the bidirectional screw 322; a mounting frame 325 arranged axially along the bidirectional screw 322; a connecting rod 326 hingedly installed between the installation frame 325 and the movable seat 324, one end of the connecting rod 326 is hinged to the installation frame 325, and the other end is hinged to the movable seat 324; a roller 327 rotatably installed on the installation frame 325; a fixed rod 328 for limiting the movable seat 324, the fixed rod 328 passes through the side wall of the movable seat 324, and one end of the fixed rod 328 is fixedly connected to the installation box 321, and the other end of the fixed rod 328 is fixedly connected to the movable box 334; a telescopic member 329 fixedly installed on the fixed rod 328 and the installation frame 325.

[0037] The telescopic member 329 is composed of a fixed tube and a sliding rod; the sliding rod is slidably installed in the fixed tube; a slider 1 is fixedly installed at one end of the sliding rod sliding in the fixed tube, and a slide groove 1 matching the slider 1 is provided in the fixed tube, and the slider 1 slides in the slide groove 1. Through the limiting effect of the slider 1 and the slide groove 1, on the one hand, the fixed tube and the sliding rod will not be separated during the telescopic process, and on the other hand, the fixed tube and the sliding rod will not rotate relative to each other.

[0038] The fixing rod 328 , the connecting rod 326 , the mounting frame 325 , and the roller 327 are all provided in multiple groups and are evenly distributed along the circumference of the bidirectional screw 322 .

[0039] When the pipe fittings are clamped and fixed, the pipe fittings are sleeved on the outside of the roller 327. At this time, the power source 3 is started to drive the bidirectional screw 322 to rotate. The bidirectional screw 322 drives the two moving seats 324 to approach each other, and then drives the connecting rod 326 to approach each other. The moving seats 324 drive the adjacent mounting frames 325 to prop up outward, and the mounting frames 325 drive the roller 327 box to prop up outward, so that the inner wall of the pipe fittings can be clamped and fixed, thereby preparing for the electroplating of the pipe fittings.

[0040] Since the two movable seats 324 are close to each other, the distance of the connecting rod 326 can be adjusted, and then the distance of the roller 327 propped outward can be adjusted, so that pipes with different diameters can be clamped and fixed, thereby improving the scope of use.

[0041] Furthermore, when the mounting frame 325 moves, the telescopic member 329 can be driven to extend and retract. By setting the telescopic member 329, the mounting frame 325 can be prevented from shaking or deflecting, thereby improving the stability of the mounting frame 325, and further improving the stability of the roller 327 clamping the pipe. The telescopic members 329 on each mounting frame 325 can also be arranged in multiple groups, thereby ensuring the stability of the roller 327 clamping the pipe.

[0042] In addition, the clamping components 32 are provided in multiple groups, which can clamp and fix multiple pipe fittings, thereby realizing electroplating processing of multiple pipe fittings and improving work efficiency.

[0043] As a further extension of the present invention: Since a plating area is reserved in the center of the plating tank 2, when the stirring mechanism 4 stirs the plating solution, the plating solution in the plating area may not be fully stirred, resulting in uneven distribution of metal ions in the plating solution in the plating area, affecting the electroplating effect.

[0044] The revolution assembly 33 includes: a rotating frame 331 rotatably mounted on the movable frame 31; a second power source 332 driving the rotating frame 331 to rotate, and the second power source 332 is fixedly mounted on the movable frame 31; a limit frame 333 fixedly mounted on the rotating frame 331; a movable box 334 slidably mounted in the limit frame 333, and the clamping assembly 32 is installed at the bottom of the movable box 334.

[0045] When the pipe is moved into the electroplating tank 2, the power source 2 332 is started to drive the rotating frame 331 to rotate, the rotating frame 331 drives the limit frame 333 to rotate, and the limit frame 333 drives the movable box 334 to rotate, thereby driving the pipe to rotate, so that the pipe rotates along the circumference of the electroplating tank 2.

[0046] It is to be added here that the second power source 332 is preferably: a motor.

[0047] The lifting assembly 34 includes: a cylinder 341 fixedly mounted on the movable frame 31; a guide groove 342 opened on the cylinder 341, the guide groove 342 is an annular groove with a uniform waveform, and the guide groove 342 is opened on the outer side of the cylinder 341 along the circumference of the cylinder 341; a limiting groove 343 opened in the guide groove 342, and the limiting groove 343 is opened on the inner wall of the guide groove 342 along the path of the guide groove 342; a linkage gear 344 rotatably mounted on the movable box 334; a rolling element 345 fixedly mounted on the linkage gear 344; the rolling element 345 is rollingly mounted in the limiting groove 343.

[0048] When the movable box 334 rotates, it can drive the connecting gear 344 to rotate, and the connecting gear 344 drives the second rolling member 345 to rotate. Since the second rolling member 345 is rollingly installed in the limiting groove 343, when the second rolling member 345 rolls along the path of the limiting groove 343, it can drive the connecting gear 344 to perform lifting and reciprocating movements, and the connecting gear 344 drives the movable box 334 to perform lifting and reciprocating movements, thereby driving the pipe fitting to perform lifting and reciprocating movements.

[0049] It is to be added here that the second rolling element 345 is preferably a bull's eye ball.

[0050] The self-rotating assembly 35 includes: a tooth block 351 fixedly installed in the guide groove 342, the tooth block 351 is fixedly installed at the bottom of the inner cavity of the guide groove 342 along the path of the guide groove 342, the linkage gear 344 and the tooth block 351 are meshed with each other; an active bevel gear 352 coaxially connected to the linkage gear 344; a driven bevel gear 353 and a linkage bevel gear 354 rotatably installed in the movable box 334, and the driven bevel gear 353 and the linkage bevel gear 354 are coaxially connected; a telescopic shaft 355 rotatably installed on the movable box 334; a connecting bevel gear 356 fixedly installed at one end of the telescopic shaft 355; a driving bevel gear 357 fixedly installed at the other end of the telescopic shaft 355; a transmission bevel gear 358 meshed with the driving gear; the active bevel gear 352 and the driven bevel gear 353 are meshed with each other; the linkage bevel gear 354 and the connecting bevel gear 356 are meshed with each other; and the transmission bevel gear 358 is coaxially connected to the roller 327.

[0051] The telescopic shaft 355 is composed of a rotating tube and a rotating rod, and the rotating rod is slidably installed in the rotating tube; a slider 2 is fixedly installed on one end of the rotating rod sliding in the rotating tube, and a slide groove 2 matching the slider 2 is opened in the rotating tube. The slider 2 slides in the slide groove 2. Through the limiting effect of the slider 2 and the slide groove 2, on the one hand, the rotating tube and the rotating rod will not be separated during the telescopic process, and on the other hand, the rotating tube and the rotating rod can rotate synchronously.

[0052] When the linkage gear 344 moves along the path of the guide groove 342, since the linkage gear 344 and the tooth block 351 are meshed with each other, the linkage gear 344 can rotate while moving along the path of the guide groove 342, thereby driving the active bevel gear 352 to rotate, the active bevel gear 352 drives the driven bevel gear 353 to rotate, the driven bevel gear 353 drives the linkage bevel gear 354 to rotate, the linkage bevel gear 354 drives the telescopic shaft 355 to rotate, the telescopic shaft 355 drives the driving bevel gear 357 to rotate, the driving bevel gear 357 drives the transmission bevel gear 358 to rotate, and then drives the roller 327 to rotate. The rotation of the roller 327 can drive the pipe fitting to rotate along the circumferential direction of the bidirectional screw 322, thereby realizing the self-rotation of the pipe fitting.

[0053] It should be added here that by rolling the second rolling member 345 along the path of the limiting groove 343, on the one hand, it can limit the connecting gear 344, so that the connecting gear 344 moves along the path of the guide groove 342, avoiding the displacement of the connecting gear 344 in the guide groove 342, and on the other hand, it can ensure that the connecting gear 344 is always engaged with the tooth block 351.

[0054] Through the above-mentioned mechanism, the pipe fittings can be lifted, revolved and rotated at the same time during the electroplating process in the electroplating area. On the one hand, the plating liquid in the electroplating area can be fully stirred, so that the metal ions in the plating liquid of the entire electroplating tank 2 are evenly distributed, ensuring the electroplating effect; on the other hand, the pipe fittings can be fully contacted with the plating liquid, further ensuring the electroplating effect.

[0055] In addition, when the roller 327 drives the tube to rotate, the contact position between the tube and the roller 327 can be continuously changed, thereby avoiding the problem of incomplete electroplating of the tube due to insufficient contact with the electroplating solution at the contact position, and further ensuring the electroplating effect.

[0056] The stirring mechanism 4 also includes: a circulation component 47 that drives the plating liquid in the plating tank 2 to circulate; the circulation component 47 includes: a capsule 471 fixedly installed in the fixed box 461; a liquid inlet pipe 472 connecting the liquid inlet end of the capsule 471 and the rotating tube 4691, the liquid inlet end of the liquid inlet pipe 472 is rotatably connected to the bottom end of the rotating tube 4691, and a first one-way valve is installed on the liquid inlet pipe 472; a liquid outlet pipe 473 connecting the liquid outlet end of the capsule 471 and the plating tank 2, and a second one-way valve is installed on the liquid outlet pipe 473; a filtering unit 474 for filtering the plating liquid; the capsule 471 is fixedly connected to the movable frame 465.

[0057] When the movable frame 465 moves up and down reciprocatingly along the axis of the sleeve 464, it can drive the capsule 471 to compress and recover. When the capsule 471 is compressed, the first one-way valve is closed and the second one-way valve is opened. At this time, the plating liquid in the capsule 471 can be transported to the electroplating tank 2 through the liquid outlet pipe 473; when the capsule 471 recovers, the first one-way valve is opened and the second one-way valve is closed. At this time, the plating liquid in the electroplating tank 2 can be transported to the capsule 471 through the liquid inlet pipe 472, thereby realizing the circulation of the plating liquid in the electroplating tank 2, thereby improving the uniformity of mixing of the plating liquid, and further ensuring the electroplating effect of the pipe fittings.

[0058] Since waste residue will be generated in the electroplating solution during the electroplating process, it will adhere to the surface of the pipe fittings during electroplating, causing defects on the surface of the pipe fittings and affecting the quality of electroplating.

[0059] The filter unit 474 includes: a filter screen 4741 fixedly installed in the liquid inlet pipe 472; a turbine 4742 rotatably installed in the liquid inlet pipe 472, a fixing bar fixedly installed in the liquid inlet pipe 472, and the turbine 4742 is rotatably installed on the fixing bar; a cleaning brush 4743 coaxially connected to the turbine 4742, and the bristle side of the cleaning brush 4743 abuts against the filter screen 4741; a discharge pipe 4744 connected to the liquid inlet pipe 472, and a control valve is installed on the discharge pipe 4744.

[0060] When the electroplating solution circulates, the filter screen 4741 can be used to filter the electroplating solution to remove residual waste residue in the electroplating solution, thereby ensuring the electroplating quality of the pipe fittings.

[0061] When the electroplating liquid flows, it can drive the turbine 4742 to rotate, and the turbine 4742 drives the cleaning brush 4743 to rotate, so that the waste residue attached to the filter screen 4741 can be cleaned, thereby ensuring the filtering effect of the filter screen 4741, and the cleaned waste residue is deposited in the discharge pipe 4744.

[0062] When the waste residue in the discharge pipe 4744 is cleaned, the control valve is opened to discharge the waste residue through the discharge pipe 4744 for subsequent use.

[0063] The present invention realizes the circulation of the plating solution in the plating tank 2 through the setting of the filtering unit 474, thereby improving the uniformity of mixing of the plating solution and further ensuring the plating effect of the pipe fittings; on the other hand, the plating solution can be filtered to remove the residual waste residue in the plating solution and ensure the plating quality of the pipe fittings.
