Background technique

In order to improve the wear resistance, electrical conductivity or corrosion resistance of the workpiece, a layer of other metals or alloys is usually plated on the surface of the workpiece using the principle of electrolysis. This process is electroplating. Electroplating is a step that needs to be carried out for most metal workpieces. After the electroplating is completed, an electroplating layer will be formed on the surface of the metal workpiece. In order to improve the effect of the electroplating layer, the metal workpiece is usually subjected to post-plating treatment, that is, the workpiece is then washed with water and light out. , passivation and hydrogen drive processing to improve the quality of electroplating.

The existing utility model patent with the publication number CN207109105U discloses a multi-step post-treatment system for electroplating layers, including a base, a main treatment tank, a vacuum drying oven, a bleaching tank, and a final cleaning tank; wherein the main treatment tank and the base are slidably connected , the base is provided with a motor that drives the main processing tank to rotate; the main processing tank includes a feed port, a light output tank, a first cleaning tank, a passivation tank, a second cleaning tank and a discharge port. During processing, put the electroplated workpiece into the feeding port, then start the motor, the motor drives the main processing tank to rotate, and the workpiece enters the light-emitting tank, the first cleaning tank, the passivation tank and the second cleaning tank in turn, and finally the material is discharged from the discharge tank. The mouth falls out, and then goes through the processing of vacuum drying oven, bleaching tank and final cleaning tank to complete the electroplating post-processing of the workpiece.

The prior art solution in the above has the following defects: after a large number of workpieces are put into the feed port, the workpieces are in contact with each other, and the workpieces only undergo simple translation during the process of light extraction, cleaning, passivation and re-cleaning of the workpieces. The relative movement between the workpiece and the workpiece is not easy to occur, so that the contact between the workpiece and the workpiece is not fully processed, which reduces the quality of the workpiece after electroplating, thereby reducing the quality of the workpiece.

Utility model content

In view of the deficiencies in the prior art, the purpose of this utility model is to provide a multi-step post-processing system for the electroplating layer of the electroplated workpiece, which has the advantages of sufficient workpiece processing, high precision of the electroplating post-processing of the workpiece, and high quality of the workpiece. Effect.

The above-mentioned purpose of the present invention is achieved through the following technical solutions:

A multi-step post-treatment system for electroplated layers of electroplated workpieces, comprising a bracket and a heater located on one side of the bracket, wherein a water washing tank, a light emitting tank, a rewashing tank and a passivation tank are arranged in the bracket in sequence, and the water washing tank, The light-emitting tank, the re-washing tank and the passivation tank are all rotatably connected with the bracket, the outer peripheral surfaces of the water-washing tank, the light-emitting tank, the re-washing tank and the passivation tank are all provided with racks, and the bracket is provided with a number of rotating drives, The output ends of the rotary drivers are all connected with driving gears, and the racks on the outer peripheral surfaces of the water washing tank, the light-emitting tank, the re-washing tank and the passivation tank are respectively meshed with the driving gears on a rotary driver; and a hook is also included. , the lower end of the hook is provided with a hook, and the hook is detachably connected with a mesh cage for holding the workpiece.

Using the rewash tank can prevent the light-extracting agent on the surface of the workpiece from contacting the passivation agent in the passivation tank, reduce the purity of the passivation agent, and affect the final passivation accuracy. On the one hand, a large amount of light-extracting agent is prevented from adhering to the surface of the workpiece, resulting in insufficient contact between the workpiece and the passivation agent, and reducing the passivation processing accuracy of the workpiece; therefore, the rewashing tank ensures the processing quality of the workpiece, thereby improving the overall quality of the workpiece. In addition, although the re-washing tank and the water-washing tank both use clean water to wash the workpiece, the attachments or components used on the surface of the workpiece are different. Therefore, different tanks are used to clean the workpiece, which is convenient for the later classification of wastewater and protects the environment. .

The workpiece cleaned by the rewash tank is put into the passivation tank and contacts with the passivation agent in the passivation tank. The passivation process makes the electroplating layer of the workpiece less susceptible to corrosion and slows down the oxidation speed of the electroplating layer. Finally, the workpiece is put into the heater, and the workpiece is subjected to hydrogen drive processing, so that the workpiece is not easily damaged and the service life of the workpiece is prolonged. Cleaning, light extraction, passivation and hydrogen drive improve the performance and quality of the electroplating layer of the workpiece, so that the quality of the workpiece is improved and the service life is longer.

The circulation pipe and suction pump avoid this phenomenon, and spray the solution to the upper end of the mesh cage, so that the workpiece in the mesh cage can be fully processed, and the processing quality of the workpiece is improved, thereby improving the quality of the workpiece.

In a preferred example of the present invention, a plurality of shunt pipes are connected to the circulation pipe above the suction pump, and the shunt pipes are communicated with the inside of the tank body.

By adopting the above technical scheme, the shunt pipe is inserted into the tank from different directions, so that the solution in the shunt pipe is sprayed to the upper end of the mesh cage from different directions, further ensuring the full processing of the workpiece. In addition, when the mesh cage enters the tank and is about to leave the tank, the solution will be sprayed into the mesh cage to ensure full contact between the workpiece and the solution.

In a preferred example of the present invention, it can be further configured that: the end of the shunt pipe located inside the tank is connected with a shunt nozzle, and the shunt nozzle is provided with a plurality of shunt holes.

By adopting the above technical scheme, the shunt nozzle enlarges the coverage area of the solution sprayed from the shunt pipe, so that the workpiece is fully contacted with the solution, and the processing quality of the workpiece is improved, thereby improving the quality of the workpiece.

In a preferred example of the present invention, it can be further configured that the lower ends of the water washing tank, the light emitting tank, the rewashing tank and the passivation tank are all provided with liquid leakage ports, and the liquid leakage ports are detachably connected with sealing covers.

By adopting the above technical scheme, the conical structure facilitates the outflow of the solution in the tank. On the one hand, the conical structure speeds up the outflow of the solution in the tank and improves the efficiency of drainage; on the other hand, the conical structure makes it difficult for residual liquid to remain in the tank, thereby ensuring the purity of the solution newly added to the tank and improving the quality of the workpiece.

In a preferred example of the present invention, it can be further configured that: the hook is provided with a shielding plate for preventing the solution inside the tank from splashing out of the tank.

By adopting the above technical solution, the shielding plate protects the safety of the workers and prevents the solution from being splashed on the workers' bodies or clothes. The shielding plate also improves the cleanliness of the working environment, and prevents the solution from sputtering to the outer peripheral side of the bracket, which will cause harm to the working environment.
