Description

Technical Field

[0001] This utility model relates to the field of electroplating solution recovery technology, and in particular to an electroplating solution overflow recovery type plating tank equipment. Background Technology

[0002] Electroplating solution is a solution used in electroplating processes. It consists of main salts, conductive salts, additives, and other components, and functions to expand the range of cathode current densities, improve the appearance of the coating, and enhance its antioxidant stability. The main salts provide metal ions, the conductive salts improve the conductivity of the solution, and the additives refine the coating structure and optimize its performance.

[0003] However, in existing technologies, impurities in the electroplating solution can affect the stability of the electroplating reaction, leading to problems such as unevenness, inconsistent thickness, and poor gloss in the electroplated layer, which reduces the surface quality of the workpiece. Impurities can also interfere with the deposition process of metal ions on the electrode, reducing electroplating efficiency. In some cases, it may even be necessary to increase the current density to compensate for this effect, thereby increasing energy consumption and further affecting the economy and quality stability of the electroplating process. Utility Model Content

[0004] The purpose of this invention is to solve the problem that impurities in the electroplating solution can affect the stability of the electroplating reaction, resulting in uneven electroplating layers, inconsistent thickness, and poor gloss. Therefore, this invention proposes an electroplating solution overflow recovery type plating tank device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an electroplating tank equipment for overflow recovery of electroplating solution, comprising an electroplating tank and overflow troughs fixedly connected to both sides thereof, and a recovery mechanism installed on both sides of the inner cavity of the electroplating tank; The recycling mechanism includes two movable frames and a support plate fixedly connected to the inner wall of the electroplating tank. A drive motor is installed on the top of the support plate. A support frame is fixedly connected to the bottom of the inner cavity of the electroplating tank. A driven wheel is rotatably connected to the inner side of the support frame. Cranks are fixedly connected to both sides of the shaft end of the driven wheel. A drive block is fixedly connected to one end of the crank. A second linkage rod is rotatably connected to the side wall of the movable frame. A first linkage rod is rotatably connected to one end of the second linkage rod. A drive plate is fixedly connected to the side wall of the first linkage rod. The drive plate and the drive block are slidably connected.

[0006] Preferably, a floating plate is fixedly connected to the inner side of the movable frame, and a first transmission rod is rotatably connected to the side wall of the movable frame.

[0007] Preferably, a second transmission rod is rotatably connected to the bottom end of the first transmission rod, and a first support block is rotatably connected to one end of the second transmission rod.

[0008] Preferably, one end of the first linkage rod is rotatably connected to a second support block that is fixedly connected to the electroplating tank, and the bottom of the first support block is fixedly connected to the electroplating tank.

[0009] Preferably, a drive wheel is fixedly connected to the output end of the drive motor, and a synchronous belt is sleeved on the outer surface of the drive wheel.

[0010] Preferably, the bottom end of the timing belt is fitted onto the outer surface of the driven pulley.

[0011] Preferably, a filter screen is installed inside the overflow tank, and a recovery pipe is fixedly connected to the bottom of the overflow tank via a water pump.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the rotation of the driven wheel drives the crank to rotate synchronously. The circular motion of the crank causes the drive block to slide inside the drive plate, thereby affecting the movement of the first linkage rod. The first linkage rod swings around the fulcrum, driving the second linkage rod to move and pushing the movable frame to move up and down. In order to ensure the stable movement of the movable frame, the first transmission rod and the second transmission rod work together to maintain its stability and avoid mechanical failure or uneven workpiece quality caused by unstable movement. Through precise cooperation and force transmission, each component ensures that the movable frame moves up and down stably during the electroplating process, so that the electroplating solution can overflow smoothly and be easily recycled, ultimately ensuring the electroplating effect. 2. In this utility model, driven by the drive motor, the driving wheel drives the synchronous belt to rotate, and the driven wheel starts to rotate continuously, completing the power transmission. The movable frame moves up and down reciprocally under the support of the support block through the connection of the transmission rod. The up and down movement of the floating plate causes the electroplating solution in the electroplating tank to float. The electroplating solution flows into the overflow tank through the gaps on both sides of the tank, and impurities are removed by the filter screen. Then, it is transported back to the electroplating tank through the water pump and the recovery pipe, forming the recovery and circulation of the electroplating solution. The floating plate and the filter screen effectively ensure the uniform stirring and cleanliness of the electroplating solution. The recovery mechanism improves the utilization efficiency of the electroplating solution and reduces waste. Attached Figure Description

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Example 1: As Figures 1-4 As shown, this utility model provides an electroplating tank equipment for overflow recovery of electroplating solution, including an electroplating tank 1 and overflow tanks 2 fixedly connected to both sides of it, and a recovery mechanism 3 installed on both sides of the inner cavity of the electroplating tank 1. The recycling mechanism 3 includes two movable frames 33 and a support plate 32 fixedly connected to the inner wall of the electroplating tank 1. A drive motor 31 is installed on the top of the support plate 32. A support frame 362 is fixedly connected to the bottom of the inner cavity of the electroplating tank 1. A driven wheel 361 is rotatably connected to the inner side of the support frame 362. Cranks 37 are fixedly connected to both sides of the shaft end of the driven wheel 361. A drive block 371 is fixedly connected to one end of the crank 37. A second linkage rod 39 is rotatably connected to the side wall of the movable frame 33. A first linkage rod 38 is rotatably connected to one end of the second linkage rod 39. A drive plate 382 is fixedly connected to the side wall of the first linkage rod 38. The drive plate 382 is slidably connected to the drive block 371.

[0018] The specific setup and function of this embodiment will be described in detail below. During the electroplating process, the rotational motion of the driven wheel 361 drives the two cranks 37 to rotate synchronously. The cranks 37 rotate in a circular motion, which in turn causes the drive block 371 to slide inside the drive plate 382. The force generated by the sliding of the drive block 371 acts on the drive plate 382, ​​thereby affecting the movement of the first linkage rod 38.

[0019] The first linkage 38 swings around the second support block 381 as a fulcrum. This swinging motion drives the second linkage 39 to move together, thereby driving the movable frame 33 to move up and down. To ensure the stability of the movable frame 33 during movement, the first transmission rod 34 and the second transmission rod 35 work together to maintain the smoothness of the movable frame 33 during up and down movement, avoiding mechanical failures caused by unstable movement or uneven workpiece quality during electroplating.

[0020] Through the precise coordination and force transmission of each component, the movable frame 33 can maintain stable up-and-down movement during the electroplating process, thereby causing the electroplating solution to overflow for easy recycling and ensuring the electroplating effect.

[0021] Example 2: Figures 2-4 As shown, a floating plate 331 is fixedly connected to the inner side of the movable frame 33, and a first transmission rod 34 is rotatably connected to the side wall of the movable frame 33. A second transmission rod 35 is rotatably connected to the bottom end of the first transmission rod 34, and a first support block 351 is rotatably connected to one end of the second transmission rod 35. A second support block 381, which is fixedly connected to the electroplating tank 1, is rotatably connected to one end of the first linkage rod 38, and the bottom of the first support block 351 is fixedly connected to the electroplating tank 1. A drive wheel 311 is fixedly connected to the output end of the drive motor 31, and a synchronous belt 36 is sleeved on the outer surface of the drive wheel 311. The bottom end of the synchronous belt 36 is sleeved on the outer surface of the driven wheel 361. A filter screen 21 is installed inside the overflow tank 2, and a recovery pipe 22 is fixedly connected to the bottom of the overflow tank 2 through a water pump.

[0022] The overall effect of this embodiment is that, driven by the drive motor 31, the drive motor 31 generates power through its output shaft, thereby driving the drive wheel 311 to rotate. The rotation of the drive wheel 311 causes the synchronous belt 36 connected to it to start running, driving the driven wheel 361 to rotate continuously, thereby realizing the transmission of power and motion control.

[0023] When the movable frame 33 moves up and down, the first transmission rod 34 and the second transmission rod 35 work together through a precision connection to support the reciprocating motion of the movable frame 33 in the vertical direction. Specifically, the first support block 351 acts as a support component, ensuring the stability of the movement of the first transmission rod 34 and the second transmission rod 35, and effectively bearing the reaction force from the up-and-down movement of the movable frame 33. This design not only ensures the smooth movement of the movable frame 33, but also improves its durability and vibration resistance.

[0024] Furthermore, the floating plate 331 equipped on the movable frame 33 plays a crucial role in the movement process. Through the up-and-down movement of the floating plate 331, the electroplating solution in the electroplating tank 1 begins to float and agitate, a process that effectively promotes uniform circulation and stirring of the electroplating solution. With the action of the floating plate 331, the liquid surface on both sides of the electroplating tank 1 fluctuates, and the electroplating solution flows from the openings on both sides of the electroplating tank 1 to the overflow tank 2. In the overflow tank 2, the electroplating solution is filtered by the filter screen 21 to remove impurities and particles, ensuring the cleanliness of the liquid.

[0025] The filtered electroplating solution is then efficiently pumped back to the electroplating tank 1 along the recovery pipe 22. This recycling and circulation process helps maintain the quality and stability of the electroplating solution, while reducing waste and lowering production costs. Through this recycling mechanism, the utilization efficiency of the electroplating solution is greatly improved, and resource conservation and environmental protection are achieved to a certain extent.

[0026] The operating principle and usage of this device are as follows: During the electroplating process, the rotation of the driven wheel 361 simultaneously drives the two cranks 37 to rotate. When the cranks 37 move in a circular motion, they exert a force on the drive plate 382 through the sliding of the drive block 371, thereby driving the first linkage rod 38 to move. The first linkage rod 38 oscillates around the second support block 381, which in turn drives the second linkage rod 39 to move, enabling the movable frame 33 to move up and down. During this process, the movable frame 33 maintains stable movement under the cooperative support of the second transmission rod 35 and the first transmission rod 34.

[0027] The drive motor 31 drives the drive wheel 311 to rotate, and transmits power to the driven wheel 361 through the synchronous belt 36, causing it to rotate continuously. When the movable frame 33 moves up and down, the first transmission rod 34 and the second transmission rod 35, supported by the first support block 351, work together to maintain the smooth reciprocating motion of the movable frame 33.

[0028] As the movable frame 33 floats, the floating plate 331 agitates the electroplating solution in the electroplating tank 1, causing it to ripple and overflow from the gaps on both sides of the electroplating tank 1 into the overflow tank 2. After being filtered by the filter screen 21, the electroplating solution is transported back to the electroplating tank 1 by the action of the water pump and the recovery pipe 22, realizing the recycling of the electroplating solution.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
