Description

Technical Field

[0001] This utility model relates to the field of electroplating tank technology, specifically a metal electroplating tank with waste liquid recovery function. Background Technology

[0002] Electroplating is a process that uses the principle of electrolysis to plate a thin layer of another metal or alloy onto the surface of a metal to change the surface properties or dimensions of the substrate. The electroplating tank is used to hold the electroplating solution and is the main equipment for the electroplating operation.

[0003] In practical applications, after electroplating a workpiece, it needs to be extracted from the electroplating solution. After extraction, a significant amount of liquid remains on the workpiece's surface. Directly removing the workpiece results in substantial waste of the electroplating solution. To overcome this drawback, existing technology (Chinese patent application number 202322723250.5, application date 2023-10-11) provides an electroplating tank for zinc-nickel metal plating. This tank incorporates a draining mechanism, where the electroplated workpiece is hung above the draining box for drainage, thus preventing water from seeping through the plating solution. The electroplating solution carried by the workpiece is drained into the water collection tank and then transported to the electroplating tank body through the liquid delivery pipeline. This avoids waste of electroplating solution, saves on the consumption of electroplating solution, thereby reducing product energy consumption and achieving energy saving. It solves the problem that directly removing the workpiece will result in a large amount of electroplating solution loss and waste. However, relying solely on the natural sliding of the electroplating solution during drainage results in a limited amount of recoverable electroplating solution, which will still result in a significant loss. Furthermore, during use, the electrolyte in the electroplating tank will gradually show uneven distribution of metal ions, which will affect the electroplating quality of the workpiece.

[0004] To address the aforementioned issues, innovative designs are urgently needed based on existing equipment. Therefore, we have proposed a metal electroplating tank with waste liquid recovery function, which can effectively solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a metal electroplating tank with a waste liquid recovery function, so as to solve the problems mentioned in the background art, which rely solely on the natural dripping of electroplating liquid during drainage. This results in a limited amount of recoverable electroplating liquid and still a significant loss. Furthermore, during use, the electrolyte in the electroplating tank will gradually exhibit uneven distribution of metal ions, which will affect the electroplating quality of the workpiece.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a metal electroplating tank with waste liquid recovery function, comprising an electroplating tank body, a lifting mechanism being provided above the electroplating tank body, and a lifting rod being fixedly connected to the bottom end of the lifting mechanism, with several hanging devices hooked on the lifting rod; a recovery box being provided at one end of the electroplating tank body, and a suction pump being provided between the electroplating tank body and the recovery box, with the input and output ends of the suction pump being connected to the electroplating tank body and the recovery box respectively through connecting pipes; a swing assembly being provided on the outside of the lifting rod, the swing assembly... The swing assembly includes a limiting collar that is rotatably sleeved on the outside of the hanging rod, and a hanger limiting clamp is engaged with the inside of the limiting collar. A toothed ring is fixedly connected to one side of the limiting collar. Two fixing plates are fixedly connected to the top of one side of the electroplating tank at both ends of the toothed ring. Multiple sets of toothed racks are formed on the end faces of the two fixing plates that are close to each other, and the multiple sets of toothed racks are staggered and located above the toothed ring. A stirring assembly is provided inside the electroplating tank to stir the electrolyte in the electroplating tank so that the metal ions are evenly distributed to ensure the electroplating quality of the workpiece.

[0007] Preferably, the top of the recycling bin is slidably covered with a cover plate, and a handle is fixedly connected to the cover plate to ensure that the electroplating solution is sealed and stored in the recycling bin, and the handle makes it easy to open the cover plate.

[0008] Preferably, the outer side of the limiting collar is provided with several hook grooves, and the hanger is correspondingly limited and engaged inside the hook groove.

[0009] Preferably, a stabilizing member is fixedly connected to one top side of the electroplating tank, which is used to stabilize the two fixing plates.

[0010] Preferably, the stirring assembly includes a movable shaft slidably connected to the bottom of the electroplating tank. Stirring blades are fixedly connected to the outer wall of the movable shaft. Two gear end plates are fixedly connected to the outer walls of both ends of the movable shaft, and multiple connecting frames are fixedly connected between the outer edges of the two gear end plates. Multiple evenly distributed protruding teeth are formed on the inner wall of the bottom of the electroplating tank, and the protruding teeth mesh with one of the gear end plates. An electric lead screw is installed inside the electroplating tank, and a movable seat is threaded to the outer side of the electric lead screw. One end of the movable shaft is rotatably connected to the movable seat.

[0011] Preferably, an elongated groove is formed on the inner wall of one end of the electroplating tank, and the end of the movable shaft away from the movable seat is limited to slide inside the elongated groove.

[0012] Preferably, the electric lead screw is composed of a motor part fixedly installed on the outer wall of the electroplating tank and a lead screw part rotatably connected between the two side walls of the electroplating tank, and a sealed bearing is installed between the lead screw and the side wall of the electroplating tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the metal electroplating tank with waste liquid recycling function can pump the electroplating waste liquid in the electroplating tank to the recycling tank for recycling by using the recycling tank and the suction pump; by setting up the swing component, when the lifting mechanism drives the lifting rod and the hanger to lift upward, the workpiece will throw the electroplating liquid adhering to the surface back into the electroplating tank, thereby increasing the amount of electroplating liquid recycled and reducing the loss; by setting up the stirring component, the electrolyte in the electroplating tank can be stirred to make the metal ions evenly distributed, so as to ensure the electroplating processing quality of the workpiece. The specific contents are as follows: (1) by using the recycling tank and the suction pump together, when the electroplating tank is used up, the electroplating waste liquid in the electroplating tank can be pumped to the recycling tank for recycling by the suction pump.

[0014] The electroplating solution is sealed in the recycling bin by a sliding cover at the top, and a handle is fixedly connected to the cover. The handle makes it easy to open the cover.

[0015] By setting up a swing assembly, after electroplating is completed, the lifting mechanism automatically starts, driving the lifting rod, hangers, limiting collar, and toothed ring to rise synchronously. When the toothed ring moves between the racks, it will mesh with them. Because the two sets of racks are staggered, they will rotate back and forth during the upward movement of the toothed ring. This will cause the limiting collar and multiple hangers to swing synchronously, and the workpieces hooked on them will throw the electroplating solution adhering to their surfaces back into the electroplating tank, thereby increasing the amount of electroplating solution recovered and reducing its loss.

[0016] By setting up a stirring component, the electric screw is activated to drive the moving seat to move. The moving shaft, stirring blades, and gear end plate move synchronously. Due to the meshing action between the gear end plate and the teeth, the gear end plate rotates. The moving shaft and stirring blades rotate synchronously, which can uniformly stir the electroplating solution inside the electroplating tank, so that the metal ions are evenly distributed to ensure the electroplating quality of the workpiece.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figures 1-6 The present invention provides the following technical solution: a metal electroplating tank with waste liquid recycling function, including an electroplating tank body 1, a lifting mechanism 2 (this is a conventional technology in existing electroplating processes, so only the part of the structure related to this application is shown in the figure), and a lifting rod 3 is fixedly connected to the bottom end of the lifting mechanism 2, and several hanging devices 4 are hooked on the lifting rod 3.

[0026] A recycling tank 5 is provided at one end of the electroplating tank 1, and a suction pump 6 is provided between the electroplating tank 1 and the recycling tank 5. The input and output ends of the suction pump 6 are connected to the electroplating tank 1 and the recycling tank 5 respectively through connecting pipes. When the electroplating tank 1 is used up, the electroplating waste liquid in the electroplating tank 1 can be pumped to the recycling tank 5 for recycling by the suction pump 6. The top of the recycling tank 5 is covered with a cover plate 7, and a handle is fixedly connected to the cover plate 7, thereby ensuring that the electroplating liquid is sealed and stored in the recycling tank 5, and the handle can easily open the cover plate 7.

[0027] A swing assembly is provided on the outer side of the boom 3. The swing assembly includes a limiting collar 8 that is rotatably sleeved on the outer side of the boom 3, and a hanger 4 that is limited and engaged on the inner side of the limiting collar 8. Specifically, the outer side of the limiting collar 8 has several hook grooves, and the hanger 4 is correspondingly engaged and engaged inside the hook grooves, so that the hanger 4 can swing synchronously when the toothed ring 9 drives the limiting collar 8 to swing. A toothed ring 9 is fixedly connected to one side of the limiting collar 8. Two fixing plates 10 are fixedly connected to the top of one side of the electroplating tank 1 at both ends of the toothed ring 9. The end faces of the two fixing plates 10 that are close to each other are formed with multiple sets of toothed racks 11, and the multiple sets of toothed racks 11 are staggered and located above the toothed ring 9. A toothed ring 9 is fixedly connected to the top of one side of the electroplating tank 1. The stabilizing component 12 is used to stabilize the two fixed plates 10. By setting up a swing assembly, after the workpiece hooked on the hanger 4 is electroplated, the lifting mechanism 2 automatically starts to drive the lifting rod 3 and the hanger 4 to rise. The limiting collar 8 and the toothed ring 9 move upward synchronously. When the toothed ring 9 moves between the racks 11, it will mesh with them. Because the two sets of racks 11 are staggered, they will make the toothed ring 9 rotate back and forth during the rising process, which will cause the limiting collar 8 to swing. The multiple hangers 4 that are locked in the limiting collar 8 swing synchronously, and the workpiece hooked on them will shake off the electroplating liquid on the surface and fall back into the electroplating tank 1, thereby greatly increasing the amount of electroplating liquid recovered and reducing its loss.

[0028] Example 2: Based on Example 1, a stirring assembly is provided inside the electroplating tank 1 to stir the electrolyte in the electroplating tank 1, ensuring uniform distribution of metal ions and guaranteeing the electroplating quality of the workpiece. The stirring assembly includes a movable shaft 13 slidably connected to the bottom of the electroplating tank 1. Stirring blades 14 are fixedly connected to the outer wall of the movable shaft 13. Two gear end plates 15 are fixedly connected to the outer walls of both ends of the movable shaft 13, and multiple connecting brackets 16 are fixedly connected between the outer edges of the two gear end plates 15. The bottom inner wall of the electroplating tank 1... The plate has multiple evenly distributed protruding teeth 17, which mesh with one of the gear end plates 15. An electric lead screw 18 is installed inside the electroplating tank 1, and a movable seat 19 is threadedly connected to the outside of the electric lead screw 18. One end of the movable shaft 13 is rotatably connected to the movable seat 19. The electric lead screw 18 is composed of a motor part fixedly installed on the outer wall of the electroplating tank 1 and a lead screw part rotatably connected between the two side walls of the electroplating tank 1. A sealed bearing is installed between the lead screw and the side wall of the electroplating tank 1 to make the lead screw rotate smoothly.

[0029] By setting up a stirring component, the electric lead screw 18 can be activated to drive the moving seat 19 to move. The moving shaft 13, stirring blade 14, gear end plate 15, and connecting frame 16 at one end of the moving seat 19 move synchronously. Due to the meshing action between the gear end plate 15 and the tooth 17, the gear end plate 15 will rotate during the movement. The moving shaft 13 and stirring blade 14 will rotate synchronously, so that the electroplating solution in the electroplating tank 1 can be uniformly stirred, so that the metal ions are evenly distributed, thereby ensuring the electroplating quality of the workpiece.

[0030] In addition, an elongated groove is provided on the inner wall of one end of the electroplating tank 1, and the end of the movable shaft 13 away from the movable seat 19 is limited to slide inside the elongated groove to ensure the stability of the movement and rotation of the movable shaft 13 and the stirring blade 14.
