Description

Technical Field

[0001] The present invention relates to the field of electroplating technology, and in particular to an automatic edge wave adjustment device for an electroplating production line. Background Art

[0002] In the traditional electroplating production process, the plating tank is usually equipped with equipment such as circulation pumps and swing mechanisms. These devices will inevitably cause the tank body to vibrate during operation, which in turn leads to unexpected and irregular fluctuations in the plating solution level.

[0003] However, the existing automatic edge wave adjustment devices for electroplating production lines still have some shortcomings in actual use: Most of the existing edge wave adjustment devices for electroplating production lines use a screw drive device to achieve height adjustment of the electroplating bath and the workpieces inside it. The screw drive device and the electroplating bath are rigidly connected. When the plating liquid level fluctuates irregularly, this rigid connection method cannot timely and effectively buffer the impact of the surface fluctuation. Due to the lack of adaptive adjustment capabilities, the electroplating bath and the workpieces inside it will shake violently with the fluctuation of the liquid level, which is very likely to cause edge waves. The edge wave phenomenon will cause the electroplating solution to be unevenly distributed on the surface of the workpiece, resulting in differences in the electroplating thickness and effect of different parts of the workpiece, seriously affecting the overall quality of the electroplated products, resulting in a decrease in product qualification rate, and increased production costs and resource waste.

[0004] To this end, we designed an automatic adjustment device for the edge waves of electroplating production lines to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic adjustment device for the edge waves of an electroplating production line to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the present invention provides an automatic adjustment device for the edge waves of an electroplating production line, comprising an electroplating tank and a float, wherein the electroplating tank contains plating liquid, the float is located in the electroplating tank, and the side walls of the float are provided with suspension cylinders. The bottom surface of the float is symmetrically fixed with guide rods on both sides, and the outer arc walls of the two guide rods are slidably sleeved with sliders. A rectangular fixed frame is fixedly arranged between the two sliders, and an electroplating bath room is fixedly connected in the rectangular fixed frame. The bottom wall of the electroplating bath room is fixedly connected with an air bag, and a boosting component is provided on the top of the float, and the boosting component is connected to the air bag through a telescopic hose.

[0007] Furthermore, the boosting assembly includes a boosting chamber, which is fixedly mounted on the top surface of the float, and a vent is provided through the side wall of the boosting chamber, and an air pipe is fixedly connected to the outer wall of the vent, and the air pipe cover is arranged on the vent and connected to the vent, and a threaded rod is rotatably connected to the inner wall of the boosting chamber, and a movable plate is threadedly connected to the thread of the threaded rod.

[0008] Furthermore, a driving motor is provided in the boost chamber, and a driving shaft of the driving motor is fixedly connected to one end of the threaded rod.

[0009] Furthermore, the movable plate is in contact with the inner wall of the boost chamber, and the movable plate is slidably connected to the inner wall of the boost chamber.

[0010] Furthermore, the bottom ends of the two guide rods are fixedly connected to limit blocks.

[0011] Furthermore, stabilizing blocks are provided at the four corners of the bottom of the floating body.

[0012] Furthermore, the material of the airbag is corrosion-resistant fluororubber, and the airbag is filled with inert gas.

[0013] Furthermore, an external controller is included, and the drive motor is electrically connected to the external controller.

[0014] Furthermore, when workpieces of different masses are placed in the electroplating bath, the drive motor is started and the threaded rod is driven to rotate. Since the threaded rod is threadedly connected to the movable plate, and the movable plate fits against the inner wall of the boost chamber, the movable plate moves horizontally in the boost chamber, while squeezing the air medium inside the boost chamber into the airbag. As the volume of air in the airbag changes, the buoyancy provided by the airbag also changes accordingly, thereby achieving the goal of maintaining the electroplating bath and the workpieces inside it at the same height in the plating solution when workpieces of different masses are replaced.

[0015] Furthermore, when factors such as the circulating pump, rocking mechanism or tank body vibration in the electroplating tank cause unexpected and irregular fluctuations in the plating solution level, the electroplating bath and the workpiece inside it adaptively slide up and down along the guide rod through the slider.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the present invention, when the circulating pump, rocking mechanism or tank body in the electroplating tank causes irregular fluctuations in the plating solution level, the electroplating bath and the workpiece inside can adaptively slide up and down along the guide rod with the help of a slider. Compared with the rigid connection method of the traditional screw drive device, this adaptive design greatly reduces the probability of the occurrence of edge wave phenomenon. It can effectively buffer the impact force caused by the surface fluctuation of the buffer, so that the workpiece maintains a relatively stable state during the electroplating process, reduces the problem of uneven electroplating caused by edge wave, and improves the overall quality of the electroplated product.

[0018] 2. In the present invention, the threaded rod is driven to rotate by a driving motor, so that the movable plate moves horizontally in the boost chamber, thereby changing the air volume in the airbag to adjust the buoyancy. This design solves the problem of difficulty in maintaining the same height when placing workpieces of different masses in the electroplating bath. There is no need for frequent manual adjustment of complex parameters, and height matching can be achieved quickly to ensure the contact effect between the workpiece and the plating solution during the electroplating process, improve the stability of the electroplating quality, and reduce the electroplating defect rate caused by height mismatch.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] See also Figures 1-4 The present invention provides a technical solution: an automatic adjustment device for the edge waves of an electroplating production line, comprising an electroplating tank 1 and a float 2, the electroplating tank 1 contains plating liquid, the float 2 is located in the electroplating tank 1, and the side walls of the float 2 are provided with suspension cylinders 3, and the bottom surface of the float 2 is symmetrically fixed with guide rods 4 on both sides, and the outer arc walls of the two guide rods 4 are slidably sleeved with sliders 5, and a rectangular fixed frame 6 is fixedly arranged between the two sliders 5, and an electroplating bath room 7 is fixedly connected in the rectangular fixed frame 6, and an air bag 8 is fixedly connected to the bottom wall of the electroplating bath room 7, and a booster component is provided on the top of the float 2, and the booster component is connected to the air bag 8 through a telescopic hose.

[0027] In specific implementation, when factors such as the circulation pump, rocking mechanism or tank body vibration in the electroplating tank 1 cause unexpected and irregular fluctuations in the plating solution level, the electroplating bath room 7 and its internal workpiece adaptively slide up and down along the guide rod 4 through the slider 5. Compared with the existing rigid connection through the screw drive device, the occurrence of edge waves caused by fluctuations in the plating solution level is effectively reduced.

[0028] See Figure 4 The boosting assembly includes a boosting chamber 9, which is fixedly mounted on the top surface of the floating body 2. A vent 10 is provided through the side wall of the boosting chamber 9. The outer wall of the vent 10 is fixedly connected to a gas pipe. The gas pipe cover is provided on the vent 10 and is connected to the vent 10. A threaded rod 11 is rotatably connected to the inner wall of the boosting chamber 9. A movable plate 12 is threadedly connected to the thread of the threaded rod 11. A driving motor 13 is provided in the boosting chamber 9. The driving shaft of the driving motor 13 is fixedly connected to one end of the threaded rod 11. The movable plate 12 is in contact with the inner wall of the boosting chamber 9, and the movable plate 12 is slidably connected to the inner wall of the boosting chamber 9.

[0029] When workpieces of different masses are placed in the electroplating bath 7, the drive motor 13 is started and drives the threaded rod 11 to rotate. Since the threaded rod 11 is threadedly connected to the movable plate 12, and the movable plate 12 fits against the inner wall of the boosting chamber 9, the movable plate 12 moves horizontally in the boosting chamber 9, and at the same time squeezes the air medium inside the boosting chamber 9 into the airbag 8. As the air volume in the airbag 8 changes, the buoyancy provided by the airbag 8 also changes accordingly, thereby achieving the goal of maintaining the electroplating bath 7 and the workpieces inside it at the same height in the plating solution when replacing workpieces of different masses.

[0030] See Figure 2 The bottom ends of the two guide rods 4 are fixedly connected to the limit blocks 14. The limit blocks 14 are set to prevent the slider 5 from separating from the guide rod 4 when sliding. Stabilizing blocks 15 are set at the four corners of the bottom of the float 2. The stabilizing blocks 15 are set to prevent the float 2 and its overall device from overturning. The material of the airbag 8 is corrosion-resistant fluororubber, and the airbag 8 is filled with inert gas to prevent the airbag 8 from being damaged in the corrosive environment of the electroplating solution. It also includes an external controller, and the drive motor 13 is electrically connected to the external controller.

[0031] Example 2

[0032] The present invention provides a technical solution: a working method of an automatic edge wave adjustment device for an electroplating production line, comprising the following steps:

[0033] When workpieces of different masses are placed in the electroplating bath 7, the drive motor 13 is started and drives the threaded rod 11 to rotate. Since the threaded rod 11 is threadedly connected to the movable plate 12, and the movable plate 12 fits against the inner wall of the boosting chamber 9, the movable plate 12 moves horizontally in the boosting chamber 9, and at the same time squeezes the air medium inside the boosting chamber 9 into the airbag 8. As the air volume in the airbag 8 changes, the buoyancy provided by the airbag 8 also changes accordingly, thereby achieving the goal of maintaining the electroplating bath 7 and the workpieces inside it at the same height in the plating solution when replacing workpieces of different masses.

[0034] When the circulating pump, rocking mechanism or tank body vibration in the electroplating tank 1 causes unexpected and irregular fluctuations in the plating solution level, the electroplating bath 7 and the workpiece inside it adapt to each other and slide up and down along the guide rod 4 through the slider 5.

[0035] Working principle:

[0036] When workpieces of different masses are placed in the electroplating bath 7, the drive motor 13 is started and drives the threaded rod 11 to rotate. Since the threaded rod 11 is threadedly connected to the movable plate 12, and the movable plate 12 fits against the inner wall of the boosting chamber 9, the movable plate 12 moves horizontally in the boosting chamber 9, and at the same time squeezes the air medium inside the boosting chamber 9 into the airbag 8. As the air volume in the airbag 8 changes, the buoyancy provided by the airbag 8 also changes accordingly, thereby achieving the goal of maintaining the electroplating bath 7 and the workpieces inside it at the same height in the plating solution when replacing workpieces of different masses.

[0037] When the circulation pump, rocking mechanism or tank body vibration in the electroplating tank 1 causes unexpected and irregular fluctuations in the plating solution level, the electroplating bath 7 and its internal workpiece adaptively slide up and down along the guide rod 4 through the slider 5. Compared with the existing rigid connection through the screw drive device, the occurrence of edge waves caused by fluctuations in the plating solution level is effectively reduced.

[0038] Moreover, the cooperation of the four sets of suspension cylinders 3 and the float 2 further improves the suspension performance of the device during use, thereby preventing the device from being submerged. The limit block 14 prevents the slider 5 from separating from the guide rod 4 during sliding.

[0039] The control method of the above-mentioned drive motor 13 and other electrical components is controlled by an external controller matched therewith, and the above-mentioned control circuit can be implemented by simple programming by technicians in this field. It is common knowledge in this field and is only used without improvement. In addition, the present invention is mainly used to protect mechanical devices.
