Description

Technical Field

[0001] The utility model relates to the technical field of electroplating technology, in particular to a uniform electroplating tank used in the electroplating technology. Background Art

[0002] Electroplating is a process that uses electrochemical principles to deposit a thin layer of metal or non-metal on the surface of metal or other conductive substrates. Because of its own advantages, it is widely used in the manufacturing industry to improve the performance, appearance and corrosion resistance of metal surfaces.

[0003] In the electroplating process, the electroplating tank is an indispensable device. It can be used to contain the electrolyte solution and the workpiece to be electroplated, and at the same time provide the functions of current transfer and workpiece suspension. The design and performance of the electroplating tank will directly affect the efficiency of the electroplating process and the quality of the coating.

[0004] However, most of the electroplating processes currently available on the market use electroplating tanks that place an anode rod and a product to be electroplated in the electroplating tank and then perform electroplating. During the electroplating process, differences in concentration and temperature in the electrolyte solution may cause the flow of substances in the solution. The slow flow rate may easily lead to uneven coating thickness on the workpiece surface, which may affect the processing quality of the product and fail to meet the needs of users.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 and Figure 2The utility model provides an embodiment: a uniform electroplating tank for electroplating process, comprising a hollow box 1, a U-shaped frame 3 is arranged on the upper side of the hollow box 1, a hollow frame 4 is fixedly connected to the inner top of the U-shaped frame 3, a servo motor 5 is fixedly connected to the left side of the inside of the hollow frame 4, a worm 6 is fixedly connected to the output end of the servo motor 5, a rotating rod 7 is rotatably connected to the inside of the hollow frame 4, a half worm gear 8 is fixedly connected to the outer side of the rotating rod 7, the half worm gear 8 is meshed with the worm 6, a connecting rod 9 is fixedly connected to the bottom of the half worm gear 8, a supporting plate 10 is fixedly connected to the bottom end of the connecting rod 9, and a filter box 11 is arranged on the lower side of the supporting plate 10 An air pump 12 is arranged on the left side of the top of the hollow box 1, and the output end of the air pump 12 is connected with a connecting pipe 14, one end of the connecting pipe 14 is connected with a hollow box 15, and multiple hollow tubes 16 are equidistantly connected to the outer side of the hollow box 15, and multiple air diffusion holes 17 are equidistantly opened on the top of the hollow tube 16 and the connecting pipe 14, and the input end of the air pump 12 is connected with an air inlet pipe 13, and the left and right sides of the bottom of the support plate 10 are provided with a disassembly mechanism 2, the right end of the worm 6 is rotatably connected to the right side of the inside of the hollow frame 4, and the front and rear sides of the U-shaped frame 3 are fixedly connected with L-shaped rods 21, and the bottom ends of the two L-shaped rods 21 are fixedly connected with anode rods 22;

[0031] Specifically, the servo motor 5 drives the rotation of the worm 6. This design cleverly utilizes the meshing relationship between the worm 6 and the half worm gear 8. When the worm 6 rotates, the half worm gear 8 will rotate accordingly. This rotation method is not only stable and reliable, but also can accurately control the left and right shaking of the filter box 11. The shaking of the filter box 11 plays a key role in the flow of the electrolyte during the electroplating process. Through this design, we can ensure that the electrolyte is fully stirred and circulated inside the hollow box 1. In order to further increase the flow rate of the electrolyte, the gas can be injected into the hollow box 15 through the air pump 12, and the gas is then evenly discharged into the electrolyte through the diffuser holes 17. The injection of gas not only speeds up the flow rate of the electrolyte, but also helps to form a more uniform distribution of the electrolyte, thereby ensuring the processing quality of the product.

[0032] Reference Figure 1 , Figure 2 and Figure 3The disassembly mechanism 2 includes a fixed frame 201, which is fixedly connected to the left and right sides of the hollow box 1 respectively. The inner bottom of the fixed frame 201 is fixedly connected with a cylinder 202. The output ends of the two cylinders 202 are fixedly connected to the left and right sides of the bottom of the U-shaped frame 3 respectively. The left and right sides of the bottom of the support plate 10 are fixedly connected with support rods 203. The outer side of the support rod 203 is provided with a hollow rod 205. The top of the left and right sides of the filter box 11 is fixedly connected with a fixed plate 204. The bottom ends of the two hollow rods 205 are fixedly connected to the top of the corresponding fixed plate 204 respectively. A bolt 206 is threadedly connected to one side of the hollow rod 205. One end of the bolt 206 passes through the hollow rod 205 and the support rod 203 in sequence. The air pump 12 is fixedly connected to one side of the corresponding fixed frame 201;

[0033] Specifically, the U-shaped frame 3 can be easily lifted up by the cylinder 202. This action not only makes the filter box 11 completely exposed, but also makes the subsequent operation simple and easy. When the filter box 11 is completely exposed, the bolts 206 are screwed down in sequence, and the fixing of the filter box 11 can be quickly and effectively released, so that it can be easily taken out. After taking out the processed workpiece, we can also conveniently disassemble and clean the filter box 11, which can effectively avoid the problem of blockage of the filter box 11, thereby ensuring the stable operation of the production line, thereby greatly improving the practicality of the device, so that it can better adapt to various complex and changeable production environments.

[0034] Reference Figure 1 A controller 23 is fixedly connected to the right side of the front end of the hollow box 1. The controller 23 is electrically connected to the cylinder 202, the servo motor 5 and the air pump 12 respectively. A protective cover 24 is arranged on the outside of the controller 23. One side of the protective cover 24 is rotatably connected to the front side of the hollow box 1.

[0035] Specifically, the operation of the cylinder 202, the servo motor 5 and the air pump 12 can be controlled by the controller 23, and the protective cover 24 can protect the controller 23 from being damaged by external factors.

[0036] Reference Figure 1 and Figure 2 The lower middle part of the right side of the hollow box 1 is connected with a liquid outlet pipe 19, the right end of the liquid outlet pipe 19 passes through the hollow box 1 and is provided with a one-way valve 20;

[0037] Specifically, after the electroplating work is completed, the one-way valve 20 is opened, and the electrolyte in the hollow box 1 will be discharged through the liquid outlet pipe 19, so that the electrolyte in the hollow box 1 can be easily replaced.

[0038] Reference Figure 2 , the left and right sides of the connecting rod 9 are fixedly connected with reinforcing ribs 18;

[0039] Specifically, the reinforcing ribs 18 can further increase the activity stability of the support plate 10, thereby improving the practicability of the device.

[0040] Working principle: When using the device, first pour the workpiece to be processed into the filter box 11, then pour the electrolyte into the hollow box 1 until it covers the workpiece to be processed, and then the workpiece can be electroplated through the cooperation between the anode rod 22 and the electrolyte. At this time, the servo motor 5 can drive the worm 6 to rotate, and the half worm wheel 8 will rotate with it due to the engagement with the worm 6, thereby driving the filter box 11 to shake left and right, and then the air pump 12 can inject gas into the hollow box 15, and the gas will be discharged into the electrolyte inside the hollow box 1 through the air diffusion hole 17, which can speed up the electrolysis. The liquid flow rate can ensure that the coating thickness on the workpiece surface is relatively uniform, which will not affect the processing quality of the product and can meet the needs of users. After the electroplating work is completed, the U-shaped frame 3 can be lifted up by the cylinder 202 until the filter box 11 is completely exposed. At this time, the bolts 206 can be unscrewed in sequence to release the limit fixation of the filter box 11, and the processed workpiece can be taken out. At the same time, the filter box 11 can be disassembled and cleaned conveniently, thereby avoiding the situation where the filter box 11 is blocked and affects the subsequent processing efficiency, thereby improving the practicability of the device.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
