[0015] 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.

[0016] Embodiment 1:

[0017] See also Figures 1 to 4A chemical gold plating device includes a working box 10 and a spray assembly 20. The spray assembly 20 includes a pressure pump 21, a filter 22, a heat exchange barrel 23, and a spray nozzle arranged in the working box 10. The spray nozzle includes an upper spray nozzle 11 and a lower spray nozzle 12. A roller conveying mechanism 13 is arranged in the working box 10. The roller conveying mechanism 13 is used for material plate transmission. The upper spray nozzle 11 is located above the roller conveying mechanism 13, and the lower spray nozzle 12 is located below the roller conveying mechanism 13. The pressure pump 21 is used to extract the chemical gold plating solution and provide power to allow the chemical gold plating solution to enter the process. The chemical gold plating liquid is filtered in the filter 22, and then heated by the heat exchange barrel 23. The upper spray nozzle 11 and the lower spray nozzle 12 are connected to the output end of the heat exchange barrel 23. The upper spray nozzle 11 and the lower spray nozzle 12 evenly spray the material plate passing on the roller conveyor mechanism 13. A liquid tank 24 is also provided at the bottom of the working box 10. After the chemical gold plating liquid contacts the material plate, the remaining chemical gold plating liquid falls into the liquid tank 24 under the action of gravity, and the liquid tank 24 is connected to the input end of the pressure pump 21 through a pipeline to form a recycling system, reduce the volatilization of the chemical gold plating liquid, and further save the production cost.

[0018] Moreover, the chemical gold plating liquid can be sprayed evenly on the surface of the material plate by spraying, which reduces the replacement amount, reduces the replacement amount of gold ions, ensures the gold plating effect, and further reduces the production cost.

[0019] The upper spray nozzle 11 and the lower spray nozzle 12 are in strip shape, and the spraying direction of the upper spray nozzle 11 and the lower spray nozzle 12 is toward the roller conveyor 13. The upper spray nozzle 11 and the lower spray nozzle 12 spray sheet-shaped spray onto the material plate.

[0020] A flip door 14 is provided on the top of the working box 10, and the flip door 14 can be opened to realize the maintenance of the chemical gold plating device. The flip door 14 in this embodiment includes an outer cover layer and a glass layer (not shown), and the outer cover layer and the glass layer can be rotated separately. The glass layer can be used to observe the internal situation of the chemical gold plating device. The outer cover layer covers the outside of the glass layer to protect the glass layer. The two-layer design of the outer cover layer and the glass layer can further improve the thermal insulation effect of the working box 10 and enhance the gold plating effect.

[0021] The roller conveying mechanism 13 includes a plurality of roller assemblies 15 and a driving motor 16. The driving motor 16 is linked to the plurality of roller assemblies 15, and the plurality of roller assemblies 15 are brought to the material sheet for transmission.

[0022] Furthermore, the material plates can be horizontally transmitted through the roller conveying mechanism 13, which can be efficiently and quickly transmitted, and combined with the spraying method, the gold plating effect of the material plates can be more uniform; and the horizontal transmission of the material plates can adapt to material plates of different thicknesses, further increasing the versatility.

[0023] The invention also includes a roller assembly 17 and an air shower device 18. The roller assembly 17 is connected to the end of the roller conveying mechanism 13. A roller is arranged on the roller assembly 17, and the roller assembly 17 is linked to the driving motor 16 at the same time. The material plate contacts the roller, and the chemical gold plating liquid adhering to the material plate can be gathered under the condition of the conflict between the two, and flow back to the liquid tank 24 under the action of gravity. The air shower device 18 is located at the transmission end of the roller assembly 17. The air shower device 18 is used to blow out an airflow, which blows the material plate. The airflow can gather the chemical gold plating liquid adhering to the material plate through wind force, and flow back to the liquid tank 24 under the action of gravity. Both the roller assembly 17 and the air shower device 18 can reduce the chemical gold plating liquid from being carried away from the chemical gold plating device through the material plate, and make the chemical gold plating liquid flow back to the liquid tank to the next process for recycling, thereby further saving production costs.
