A water fed electroplating apparatus

Abstract

This application relates to a water-receiving electroplating device, including a frame, an X-Z axis moving frame, a hanging bracket, and a receiving component. The frame is sequentially equipped with an oil removal tank, a washing tank, and an electrolytic cell along the X-axis. The X-Z axis moving frame is mounted on the frame, and the hanging bracket is detachably connected to the X-Z axis moving frame and moves along the X-Z axis driven by the X-Z axis moving frame. The receiving component includes a drive unit and a water receiving tray. The drive unit is mounted on the X-Z axis moving frame and drives the water receiving tray to move along the X-axis. The water receiving tray is located below the hanging bracket when it is raised. When the hanging bracket is raised from the oil removal tank or the washing tank, the drive unit drives the water receiving tray to move along the X-axis to below the hanging bracket, thus catching any organic solutions or water dripping from the hanging bracket and preventing these liquids from dripping into the tanks of the next step. This ensures that the purity of the pure water in the washing tank is not contaminated by organic solutions, and also prevents the electrolyte in the electrolytic cell from being diluted by water, reducing subsequent processing costs and process adjustment problems caused by liquid contamination and dilution.

Description

Technical Field

[0001] This utility model relates to the field of electroplating equipment, and in particular to a water-contact electroplating equipment. Background Technology

[0002] Electroplating is a process that uses the principle of electrolysis to deposit a thin layer of another metal or alloy onto the surface of certain metals. The purpose of electroplating is to deposit a metal coating on a substrate, thereby changing the surface properties or dimensions of the substrate and improving its wear resistance, conductivity, reflectivity, corrosion resistance (such as copper sulfate), and aesthetics.

[0003] In the current electroplating process, multiple workpieces are first hung on a specially designed rack, and then a scraper is driven to move, causing the rack to pass sequentially through an ultrasonic degreasing tank, a water washing tank, and an electrolytic cell, where the workpieces are subjected to ultrasonic degreasing, ultrasonic water washing, and electroplating, respectively. However, as the rack moves from the degreasing tank to the water washing tank, the organic solution attached to the rack continuously drips down and into the water washing tank, thus affecting the purity of the pure water in the water washing tank. Similarly, as the rack moves from the water washing tank to the electrolytic cell, the water on the rack drips into the electrolytic cell, diluting the concentration of the electrolyte in the electrolytic cell. Utility Model Content

[0004] To mitigate the impact of dripping liquid on the liquid in the pool during the movement of the mounting bracket, this application provides a water-receiving electroplating device.

[0005] The water-contact electroplating equipment provided in this application adopts the following technical solution:

[0006] A water-based electroplating device includes a frame, an XZ-axis movable frame, a hanging frame, and a receiving component. The frame is provided with an oil removal tank, a water washing tank, and an electrolytic tank in sequence along the X-axis direction. The XZ-axis movable frame is mounted on the frame. The hanging frame is detachably connected to the XZ-axis movable frame and moves along the XZ-axis direction driven by the XZ-axis movable frame.

[0007] The receiving component includes a drive unit and a water receiving tray. The drive unit is mounted on the XZ axis moving frame and is used to drive the water receiving tray to move along the X-axis direction. The water receiving tray is located below the bracket in the raised state.

[0008] By adopting the above technical solution, after the hanger is raised from the degreasing tank or water washing tank, the driving component drives the water receiving tray to move along the X-axis to the bottom of the hanger. This tray can catch the organic solution or water dripping from the hanger, preventing these liquids from dripping into the tank in the next step. This ensures that the purity of the pure water in the water washing tank is not contaminated by the organic solution, and at the same time prevents the electrolyte in the electrolytic cell from being diluted by water. This improves the stability of the electroplating process and the product quality, and reduces the subsequent processing costs and process adjustment problems caused by liquid contamination and dilution.

[0009] Preferably, the XZ axis moving frame includes a second driving component, a horizontal moving frame, a third driving component, and a vertical moving frame. The horizontal moving frame is slidably connected to the frame along the X-axis direction. The second driving component drives the horizontal moving frame to move. The vertical moving frame is slidably connected to the horizontal moving frame along the Z-axis direction. The third driving component drives the vertical moving frame to move. The water receiving tray slides on the horizontal moving frame along the X-axis direction.

[0010] Preferably, the driving component includes a drive motor, a rotating rod, two first gears, and two first racks. The two first racks are fixedly mounted on both sides of the water receiving tray along the X-axis. The rotating rod is rotatably connected to a horizontal moving frame. The two first gears are coaxially fixedly mounted on both ends of the rotating rod and meshed with the two first racks. The drive motor is fixedly mounted on the horizontal moving frame, and the output shaft of the drive motor is coaxially fixedly connected to the rotating rod.

[0011] By adopting the above technical solution, when the drive motor is working, it drives the rotating rod to rotate. The first gears at both ends of the rotating rod rotate synchronously and mesh with the first rack to drive the water receiving tray to move smoothly along the X-axis. Moreover, the moving position and speed of the water receiving tray can be precisely controlled according to actual needs to ensure the reliability of the water receiving effect.

[0012] Preferably, the second driving component includes a first dual-head motor, two first shafts, two second gears, and two second racks. The first dual-head motor is fixedly mounted on a horizontal moving frame. The two first shafts are coaxially fixed on the output shafts at both ends of the first dual-head motor. The two second gears are coaxially fixed on the ends of the two first shafts. The two second racks are fixedly mounted on the frame, and the two second gears are meshed with the two second racks.

[0013] By adopting the above technical solution, when the first dual-head motor is working, it drives the two first shafts to rotate, causing the two second gears to rotate synchronously and mesh with the second rack fixed on the frame, thereby driving the horizontal moving frame to move along the X-axis direction, and thus driving the hanging frame to accurately switch positions above different pools.

[0014] Preferably, the driving component three includes a second dual-head motor, two second shafts and two connecting belts. The second dual-head motor is fixedly mounted on the horizontal moving frame. The two second shafts are coaxially fixed on the output shafts at both ends of the second dual-head motor. The two connecting belts correspond to the two second shafts respectively. One end of the connecting belt is fixed to the corresponding second shaft and then wound around the second shaft. The other end of the connecting belt is detachably connected to the vertical moving frame.

[0015] By adopting the above technical solution, when the second dual-head motor is working, it drives the two second shafts to rotate, causing the connecting belt to wind or release, thereby realizing the lifting and lowering of the vertical moving frame. The connecting belt drive structure is simple and low in cost, and can meet the functional requirements of the vertical moving frame driving the hanging frame to lift and lower. At the same time, the connection position between the connecting belt and the vertical moving frame can be easily adjusted according to actual needs to adapt to hanging frames of different sizes and weights, thus improving the versatility and flexibility of the equipment.

[0016] Preferably, the vertical moving frame is provided with two connectors, each corresponding to one of the two connecting straps. Each connector includes a fixing block and a locking block. The fixing block has a through groove for the connecting strap to pass through. The locking block is fixed to the fixing block by bolts and nuts. The locking block and the fixing block together clamp the connecting strap. The side of the locking block and the fixing block facing each other has several protrusions that insert into the connecting strap. The bottom end of the connecting strap extends out from the through groove.

[0017] By adopting the above technical solution, the connecting belt is passed through the through groove of the fixing block, and the connecting belt is clamped and fixed by the locking block and screws. This connection method is simple and reliable, and is easy to install and disassemble. When it is necessary to replace the bracket or maintain the equipment, the connecting belt can be quickly separated from the vertical moving frame, which improves the maintenance efficiency of the equipment. At the same time, it ensures that the connecting belt will not loosen during operation, ensuring the stability and safety of the vertical moving frame's lifting and lowering.

[0018] Preferably, the water receiving tray is made of transparent material. A three-way pipe is provided at the bottom of the water receiving tray. The first end of the three-way pipe connects to the inner groove of the water receiving tray, and the second end of the three-way pipe is used to connect to a water guide pipe or a plug. The third end of the three-way pipe is vertically positioned and is hinged to a plug plate via a pivot. A torsion spring is provided on the pivot, with its two ends abutting against the third end and the plug plate respectively. The torsion spring drives the plug plate to always block the third end. A force-applying block is provided on the plug plate, located on the side of the torsion spring away from the third end. A stop block is fixed to the horizontal moving frame by screws, and the force-applying block has an inclined surface facing the stop block. When the water receiving tray moves to a position directly below the hanging frame and is in a water receiving state, the stop block is positioned away from the force-applying block. When the water receiving tray moves along the side away from the hanging frame to a position directly above the previous pool body in a waiting-to-receive-water state, the stop block abuts against the inclined surface, the force-applying block tilts upward, and the plug plate and the third end form a discharge port with an acute angle.

[0019] By adopting the above technical solution, the operator can choose whether to pour the liquid in the receiving tray back into the previous tank. If the operator chooses to treat all the liquid collected in the receiving tray as waste liquid, a drain pipe is connected to the second end of the T-connector, and the stop block is removed. The third end remains sealed, allowing the water in the receiving tray to flow directly away through the drain pipe. If the operator chooses to pour the liquid collected in the receiving tray back into the original tank, a plug is installed on the second end of the T-connector. When the receiving tray is moved directly under the bracket and in the water-receiving state... When the stop block moves away from the force-applying block, the blocking plate, under the action of the torsion spring, blocks the third end of the tee pipe, preventing the liquid in the water receiving tray from flowing out. When the water receiving tray moves towards the side away from the bracket to the waiting water receiving state directly above the previous tank, the stop block abuts against the inclined surface of the force-applying block, causing the force-applying block to tilt upwards. A discharge port is formed between the blocking plate and the third end, making it convenient to discharge the liquid collected in the water receiving tray back to the previous tank, realizing the recycling of liquid, reducing liquid waste, simplifying the liquid treatment process, and improving the environmental friendliness and practicality of the equipment.

[0020] The main technical effects of this utility model are reflected in the following aspects:

[0021] 1. When the hanger is raised from the degreasing tank or the washing tank, the driving component drives the water receiving plate to move along the X-axis to the bottom of the hanger. This plate can receive the organic solution or water dripping from the hanger, preventing these liquids from dripping into the tank in the next step. This ensures that the purity of the water in the washing tank is not contaminated by the organic solution, and at the same time prevents the electrolyte in the electrolytic cell from being diluted by water. This improves the stability of the electroplating process and the quality of the product, and reduces the subsequent processing costs and process adjustment problems caused by liquid contamination and dilution.

[0022] 2. With this utility model, the operator can choose whether to pour the liquid in the receiving tray back into the previous pool. If the operator chooses to treat all the liquid in the receiving tray as waste liquid, a water guide pipe is connected to the second end of the three-way pipe, and the stop block is removed. The third end is always in a blocked state, and the water in the receiving tray can flow away directly through the water guide pipe. If the operator chooses to pour the liquid in the receiving tray back into the original pool, a plug is installed on the second end of the three-way pipe. Attached Figure Description

[0033] Reference Figures 1-4When the hanger 8 is raised from the degreasing tank 11 or the washing tank 12, the drive unit drives the water receiving tray 51 to move along the X-axis to below the hanger 8. This tray can catch the organic solution or water dripping from the hanger 8, preventing these liquids from dripping into the tank in the next step. This ensures that the purity of the pure water in the washing tank 12 is not contaminated by the organic solution, and at the same time prevents the electrolyte in the electrolytic tank 13 from being diluted by water. This improves the stability of the electroplating process and the quality of the product, and reduces the subsequent processing costs and process adjustment problems caused by liquid contamination and dilution.

The two second gears 33 are meshed with the two second racks 34.

[0038] Reference Figures 1-4When the first dual-head motor 31 is working, it drives the two first shafts 32 to rotate, causing the two second gears 33 to rotate synchronously and mesh with the second rack 34 fixed on the frame 1, thereby driving the horizontal moving frame 21 to move along the X-axis direction, and thus driving the hanging frame 8 to accurately switch positions above different pools.

[0039] Reference Figures 1-4 The driving component three includes a second dual-head motor 41, two second shafts 42 and two connecting belts 43. The second dual-head motor 41 is fixedly mounted on the horizontal moving frame 21. The two second shafts 42 are coaxially fixed on the output shafts at both ends of the second dual-head motor 41. The two connecting belts 43 correspond to the two second shafts 42 respectively. One end of the connecting belt 43 is fixed on the corresponding second shaft 42 and then wound around the second shaft 42. The other end of the connecting belt 43 is detachably connected to the vertical moving frame 22.

[0040] Reference Figures 1-4 When the second dual-head motor 41 is working, it drives the two second shafts 42 to rotate, causing the connecting belt 43 to wind or release, thereby realizing the lifting and lowering of the vertical moving frame 22. The transmission structure of the connecting belt 43 is simple and low in cost, and it can meet the functional requirements of the vertical moving frame 22 driving the hanging frame 8 to lift and lower. At the same time, the connection position between the connecting belt 43 and the vertical moving frame 22 can be easily adjusted according to actual needs to adapt to hanging frames 8 of different sizes and weights, thus improving the versatility and flexibility of the equipment.

[0041] Reference Figures 1-4 The vertical moving frame 22 is provided with two connectors 7, which correspond to two connecting belts 43 respectively.

[0042] Reference Figures 1-4 The connecting strap 43 is passed through the through groove 711 of the fixing block 71, and the connecting strap 43 is clamped and fixed by the locking block 72 and screws. This connection method is simple and reliable, and is easy to install and disassemble. When it is necessary to replace the bracket 8 or maintain the equipment, the connecting strap 43 can be quickly separated from the vertical moving frame 22, which improves the maintenance efficiency of the equipment. At the same time, it ensures that the connecting strap 43 will not loosen during operation, and ensures the stability and safety of the vertical moving frame 22 during lifting.

[0043] Reference Figure 3 , Figure 4 and Figure 5The water receiving tray 51 is made of transparent material, such as PET, PVC, PP, PE, etc. The bottom of the water receiving tray 51 is provided with a three-way pipe 6. The first end 61 of the three-way pipe 6 is connected to the inner groove of the water receiving tray 51. The second end 62 of the three-way pipe 6 is used to connect a water guide pipe or a plug. The third end 63 of the three-way pipe 6 is vertically set and is hinged to a plug plate 64 through a rotating shaft 65. A torsion spring is provided on the rotating shaft 65. The two ends of the torsion spring abut against the third end 63 and the plug plate 64 respectively. The torsion spring is used to drive the plug plate 64 to always block the third end 63. A force-applying block 66 is provided on the plug plate 64. The force-applying block 66 is located on the side of the torsion spring away from the third end 63. A stop block 68 is fixed on the horizontal moving frame 21 by screws. An inclined surface 67 facing the stop block 68 is opened on the force-applying block 66.

[0045] Reference Figure 3 , Figure 4 and Figure 5 The operator can choose whether to pour the liquid in the water receiving tray 51 back into the previous pool. If the operator chooses to treat all the liquid in the water receiving tray 51 as waste liquid, then a water guide pipe is connected to the second end 62 of the three-way pipe 6, and the stop block 68 is removed. The third end 63 is always in a blocked state, and the water in the water receiving tray 51 can flow away directly through the water guide pipe. If the liquid collected in the receiving tray 51 is to be poured back into the original pool, a plug is installed on the second end 62 of the three-way pipe 6. When the receiving tray 51 moves to the position of receiving water directly below the bracket 8, the abutment block 68 moves away from the force-applying block 66, and the plug plate 64 blocks the third end 63 of the three-way pipe 6 under the action of the torsion spring, preventing the liquid in the receiving tray 51 from flowing out. When the receiving tray 51 moves towards the side away from the bracket 8 and is in the position of waiting to receive water directly above the previous pool, the abutment block 68 abuts against the inclined surface 67 of the force-applying block 66, causing the force-applying block 66 to tilt upwards. A discharge port 69 is formed between the plug plate 64 and the third end 63, which facilitates the discharge of the liquid collected in the receiving tray 51 back into the previous pool, realizing the recycling of liquid, reducing liquid waste, simplifying the liquid treatment process, and improving the environmental friendliness and practicality of the equipment.
