Description

Technical Field

[0001] The present application relates to the technical field of electroplating processing, and in particular to a closed constant temperature electroplating processing tank. Background Art

[0002] In the manufacturing and processing industry, electroplating is a relatively common technology. Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis, which can improve the wear resistance and corrosion resistance of the workpiece. The electroplating tank device is a necessary infrastructure for electroplating technology. In the electroplating process, in order to avoid the waste of resources caused by the loss of temperature in the electroplating tank and the escape of water vapor and odor into the workshop environment, a closed constant temperature electroplating processing tank such as the Chinese patent with publication number CN220099246U is set up, and the above problems are solved by setting a sealing cover and a heating component.

[0003] However, when electroplating is performed in a sealed electroplating tank, it is inconvenient to remove and install the workpiece. Since the workpiece is placed in the middle of the electroplating tank for processing, a longer tool is required each time the workpiece is removed. Therefore, a closed constant temperature electroplating processing tank is designed. Utility Model Content

[0004] In order to solve the problem, the present application provides a closed constant temperature electroplating processing tank.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. In the utility model, the threaded rod drives the movable plate, so that the workpiece on the workpiece hanger at the lower end of the movable plate moves and approaches one side of the electroplating tank, so that when the workpiece hanger is installed on the mounting frame, it does not need to be extended by tools, and can be directly hung on the mounting frame, making the installation of the workpiece more convenient, and the use of a clamping method can facilitate the installation of the workpiece hanger on the mounting frame for electroplating processing;

[0015] 2. In the utility model, while the workpiece hanger is moved back and forth laterally, the meshing of the gear and the gear plate is also used to drive the workpiece on the workpiece hanger to rotate, so that the processing efficiency of the workpiece is better.

The rotation combined with the lateral movement can ensure that all surfaces of the workpiece are evenly contacted with fresh plating solution, and the dynamic alternating renewal of the plating solution contact surface helps to obtain a smoother and more uniform coating, and the electroplating is more comprehensive for workpieces with complex shapes or large areas.

The threaded rod 5 can be used to drive the movable plate 6 to move to the front of the electroplating tank 1, so that the lower end mounting frame 10 can be moved, so that the workpiece hanger 12 can be conveniently installed on the mounting frame 10, so that the workpiece can be conveniently placed in the electroplating tank 1 for electroplating.

[0022] And the lateral movement can help the plating solution flow more widely and evenly in the tank, thereby reducing local concentration polarization, making the concentration and thickness of the coating more consistent, and avoiding coating defects caused by insufficient plating solution flow in certain areas;

[0023] By adopting the above technical solution, the middle part of the lower end of the movable plate 6 is rotatably connected to the gear 8, one side of the gear 8 engages with the gear plate 9, one side of the gear plate 9 is fixedly connected to the inner wall of the fixed groove 41, the middle part of the lower end of the gear 8 is fixedly connected to the rotating rod, and the lower end of the rotating rod is fixedly connected to the mounting frame 10.

[0024] Rotation combined with lateral movement can ensure that all surfaces of the workpiece are evenly exposed to fresh electroplating solution, and dynamically and alternately update the contact surface of the plating solution, which helps to obtain a smoother and more uniform coating, and for complex shapes or large areas of workpieces, electroplating is more comprehensive.

[0025] By adopting the above technical solution, the front part of the threaded rod 5 is fixedly connected to the servo motor 7, and the servo motor 7 is fixedly installed on the front side wall of the cover plate 4. The servo motor 7 can drive the threaded rod 5 to rotate clockwise or counterclockwise, which is convenient for driving the reciprocating movement of the movable plate 6, so that the workpiece placed at the lower end can move horizontally in the electroplating tank 1 for more comprehensive electroplating.

[0026] By adopting the above technical solution, a mounting groove is provided at the front of the mounting frame 10, and an elastic sheet 13 is fixedly connected in the mounting groove, and a stopper 14 is fixedly connected to the upper end of the elastic sheet 13. Figure 3 As shown, the stopper 14 is trapezoidal, and the stopper 14 is slidably connected to the mounting groove, so that the stopper 14 can be lowered into the mounting groove when being squeezed by the mounting rod 11 from the front.

[0027] By adopting the above technical solution, the electric push rods 2 are fixedly connected to the two sides of the electroplating tank 1, the upper ends of the electric push rods 2 are fixedly connected to the mounting plate 3, and one side of the mounting plate 3 is fixedly connected to the cover plate 4. The mounting plate 3 can be driven to rise or fall by the electric push rods 2, so that the mounting plate 3 drives the cover plate 4 to rise or fall, thereby facilitating the opening or closing of the electroplating tank 1.

[0028] By adopting the above technical solution, heating plates 15 are fixedly installed on both sides of the electroplating tank 1. The heating plates 15 are used to maintain the temperature of the electrolyte in the electroplating tank, and the temperature is maintained at 40-80 degrees.

[0029] The implementation principle of a closed constant temperature electroplating processing tank in the embodiment of the present application is as follows: start the electric push rod 2, so that the electric push rod 2 drives the mounting plate 3 to rise, the mounting plate 3 drives the cover plate 4 to rise, and the cover plate 4 drives the mounting frame 10 to rise, and then the workpiece hanger 12 hung with workpieces is placed in the front of the mounting frame 10, and then the mounting rod 11 is pushed into the mounting frame 10, and the mounting rod 11 squeezes the stopper 14, so that the stopper 14 enters the mounting groove after being squeezed and squeezes the elastic sheet 13 to contract, and when the mounting rod 11 enters the mounting frame 10, the elastic sheet 13 blocks the mounting rod 11 after driving the stopper 14 to rise, so that the workpiece hanger 12 at the lower end of the mounting rod 11 is fixed under the mounting frame 10;

[0030] Then start the electric push rod 2 again, so that the mounting plate 3 drives the cover plate 4 to descend, and the cover plate 4 drives the workpiece hanger 12 to descend into the electroplating tank 1, and then start the servo motor 7, so that the servo motor 7 drives the threaded rod 5 to rotate, the threaded rod 5 drives the moving plate 6 to move, the moving plate 6 drives the gear 8 at the lower end to move, and the rotating rod at the lower end drives the mounting frame 10 to move, so that the mounting frame 10 drives the workpiece hanger 12 to move back and forth in the electroplating tank 1, and the lateral movement can help the electroplating solution to flow more widely and evenly in the tank, thereby reducing local concentration polarization, and the concentration and thickness of the coating are more consistent, avoiding coating defects caused by insufficient flow of the electroplating solution in some areas, and when moving, the gear 8 is meshed with the gear plate 9, so that the gear 8 rotates with its own center as the axis, and drives the mounting frame 10 at the lower end to rotate, the mounting frame 10 drives the workpiece hanger 12 to rotate, and the workpiece rotates, thereby more comprehensive electroplating. Rotation combined with lateral movement can ensure that all surfaces of the workpiece are evenly exposed to fresh electroplating solution, and dynamically and alternately update the contact surface of the plating solution, which helps to obtain a smoother and more uniform coating, and for complex shapes or large areas of workpieces, electroplating is more comprehensive.
