Abstract
Description
Technical Field
[0001] This utility model relates to the field of electroplating technology, and in particular to a quick tank changing device for a vertical continuous electroplating line. Background Technology
[0002] A vertical continuous electroplating line is a highly efficient electroplating equipment mainly used in the electronics manufacturing field (such as circuit board production). Its characteristic is that the workpiece to be processed is suspended vertically on the conveyor system and passes through multiple tanks for cleaning, electroplating, and drying in sequence, just like taking an elevator, to complete the metal coating process.
[0003] However, vertical continuous electroplating lines require frequent changes of electroplating tanks during operation to adapt to different processes (such as copper plating, nickel plating, and gold plating). When it is necessary to change the type of electroplating solution or perform maintenance, the existing practice usually requires removing the tanks filled with chemical liquids from the production line. This process is complicated and the downtime can last up to half a day, which seriously affects production capacity. At the same time, the shaking of the tanks during transportation can easily cause liquid splashing, affecting the working environment.
[0004] Therefore, a rapid tank changing device for a vertical continuous electroplating line needs to be designed. Utility Model Content

The bidirectional screw is rotatably connected to both the front and rear sides of the connecting block. The bidirectional screw is threadedly connected to the clamping block on the same side. A knob is fixed to the left side of each bidirectional screw. The controller is electrically connected to the electric push rod.
[0008] As an improvement to the above solution, the cleaning mechanism includes a vibrating plate, an ultrasonic transducer, a cleaning box, a nozzle, and a hot air dryer.

Detailed Implementation
[0022] Example: A quick-change tank device for a vertical continuous electroplating line, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the system includes a frame 1, a controller 102, an electric guide rail 2, a clamping mechanism, a motor 3, a conversion disc 4, a tank 5, a first valve body 6, a storage cylinder 15, a second valve body 16, and a cleaning mechanism. There are two frames 1, which are connected to each other and placed side-by-side. The controller 102 is mounted on the front left side of the front frame 1, and the electric guide rail 2 is located on the upper part of the rear frame 1. The clamping mechanism is mounted on the electric guide rail 2. A motor 3 is bolted to the lower middle part of both frames 1. A conversion disc 4 is connected to the upper output shaft of the motor 3 and is located on the upper side of both frames 1. The conversion plate 4 is in contact with both frames 1. The front and rear sides of the upper part of the conversion plate 4 are fixed with a trough 5. One trough 5 corresponds to one frame 1. The trough 5 is located above the frame 1 and the two form a clear vertical position relationship. A first valve body 6 is installed on one side of the lower part of both troughs 5. A storage cylinder 15 is installed on the upper part of the front frame 1. The storage cylinder 15 is located directly above the trough 5 on the lower frame 1. A second valve body 16 is connected to the bottom of the storage cylinder 15. A cleaning mechanism is provided on the front frame 1 and inside the trough 5. The controller 102 is electrically connected to the electric guide rail 2 and the motor 3.
[0023] like Figure 4 As shown, the clamping mechanism includes a guide block 9, an electric push rod 10, a connecting block 11, a clamping block 12, a bidirectional screw 13, and a knob 14. The guide block 9 is slidably connected to the electric guide rail 2. The electric push rod 10 is installed at the lower part of the guide block 9. The connecting block 11 is connected to the lower output end of the electric push rod 10. Two symmetrical clamping blocks 12 are slidably connected to both the front and rear sides of the connecting block 11. The bidirectional screw 13 is rotatably connected to both the front and rear sides of the connecting block 11. The bidirectional screw 13 is threadedly connected to the clamping block 12 on the same side. A knob 14 is fixedly connected to the left side of each bidirectional screw 13. The controller 102 is electrically connected to the electric push rod 10.
[0024] like Figure 3 and Figure 5 As shown, the cleaning mechanism includes a vibrating plate 7, an ultrasonic transducer 8, a cleaning box 17, a nozzle 18, and a hot air dryer 19. The bottom of the tank 5 is fixed with a vibrating plate 7, and multiple ultrasonic transducers 8 are installed inside the vibrating plate 7. The upper left and right sides of the front frame 1 are equipped with cleaning boxes 17, and the lower part of each cleaning box 17 is connected to and communicates with a nozzle 18. The nozzles 18 are all facing the interior of the tank 5 below. The nozzles 18 are adjustable-angle nozzles, and the spraying range of the nozzles 18 covers the entire inner wall of the tank 5. The nozzles 18 are connected to the interior of the cleaning box 17 through a flexible hose. Two hot air dryers 19 are installed in the middle of the upper part of the front frame 1. The hot air dryers 19 are located directly above the tank 5 below, and the controller 102 is electrically connected to the ultrasonic transducer 8 and the hot air dryer 19.
[0025] like Figure 1 and Figure 6 As shown, it also includes a recycling frame 20, a filter screen 21, a handle 22, and a third valve body 23. The recycling frame 20 is connected to the front side of the front frame 1. The first valve body 6 located at the lower part of the front tank 5 is connected to the recycling frame 20. The filter screen 21 is slidably connected to the upper part of the recycling frame 20. The handle 22 is welded to the front side of the filter screen 21. The third valve body 23 is connected and communicated to the lower front side of the recycling frame 20.
[0026] like Figure 1 , Figure 2 and Figure 6 As shown, it also includes foot pads 101. Multiple foot pads 101 are provided on the lower part of the frame 1. The foot pads 101 are made of rubber. The foot pads 101 absorb the vibration during the operation of the equipment, prevent the electroplating solution from shaking and splashing out or the tank 5 from shifting, and improve stability.
[0027] When using this equipment, the operator needs to place the workpiece to be processed between the clamping blocks 12. There are two sets of clamping blocks 12, which are installed on the front and rear sides of the connecting block 11 respectively. The clamping action is achieved by driving the bidirectional screw 13. The operator rotates the knob 14 to drive the bidirectional screw 13 to rotate, thereby controlling the clamping blocks 12 to move closer to the center to firmly clamp the workpiece. After clamping is completed, the operator needs to start the electric guide rail 2 through the controller 102 to drive the clamping mechanism to slide along the rail to the designated position, so that the workpiece is directly above the tank 5. Then, the electric push rod 10 is started, and its output end drives the connecting block 11 and the clamping blocks 12 to slowly descend, immersing the workpiece into the electroplating solution in the tank 5, thereby completing the electroplating operation of the current process.
[0028] When it is necessary to change the electroplating process, such as from copper plating to nickel plating, the operator first starts the motor 3 through the controller 102. The motor 3 drives the conversion disk 4 to rotate 180 degrees, turning the originally empty tank 5 located at the rear to the front working position. At the same time, the tank 5 in the original working position is moved to the rear spare position, thus completing the rapid switching between tanks 5.
[0029] To ensure a smooth transition to the next tank change, operators can pre-fill the storage tank 15 with the required electroplating solution. At this time, the tank 5 at the original work position still contains residual electroplating solution from the previous use. Therefore, the waste liquid must first be discharged into the recycling box 20 through the first valve body 6. During the recycling process, the filter screen 21 will perform preliminary filtration of solid impurities (such as electroplating debris, crystal blocks, etc.) in the waste liquid. The filtered liquid flows into the lower layer of the recycling box 20. Operators can place a collection container below the third valve body 23 to collect and discharge the waste liquid, prevent environmental pollution, and facilitate the recycling and reuse of metal residues.
[0030] After the waste liquid is discharged, residual stains may still adhere to the inner wall of tank 5. To ensure that cross-contamination does not occur during the next use, the operator needs to clean tank 5. First, clean water needs to be added to tank 5, and cleaning solution is sprayed through nozzle 18 to preliminarily soften the stains on the inner wall of tank 5. Then, the operator starts the ultrasonic transducer 8 through controller 102. It and the vibrating plate 7 together form an ultrasonic transducer. After being powered on, it generates high-frequency vibration and transfers energy to the liquid in the tank, causing the liquid molecules to move violently. During this process, the change in local pressure will promote the formation of small bubbles. The formed bubbles will break rapidly under the pressure change, generating shock waves that continuously wash the inner wall, gaps and holes of tank 5, effectively removing stains such as metal powder or crystals adhering to the inner wall of tank 5.
[0031] After cleaning, the waste liquid is discharged again through the third valve body 23 to the recycling box 20. To further improve the cleanliness of the tank, the operator can also turn on the hot air dryer 19 to dry the inside of the tank 5 to ensure that there is no moisture residue and avoid affecting the subsequent electroplating effect. Finally, the operator opens the second valve body 16 to let the new electroplating solution in the storage cylinder 15 flow into the tank 5 below, preparing for the next tank change. By repeating this cycle, the tank 5 can be changed continuously and quickly, which significantly shortens the tank change time and greatly improves production efficiency.
