Description

Technical Field

[0001] The invention relates to the technical field of electroplating of automobile parts, in particular to a device for quantitatively adding additives for electroplating of automobile parts. Background Art

[0002] Most of the auto parts need to be electroplated during production and processing. Electroplating a layer of coating on the surface of auto parts can improve the auto parts' ability to prevent metal oxidation, and improve wear resistance, conductivity, reflectivity and corrosion resistance. When the auto parts electroplating device is in use, in order to improve the electroplating efficiency and electroplating effect, electroplating additives are added to the electroplating solution to increase the activity of the anode. As the electroplating process progresses, the electroplating solution will gradually be consumed. Therefore, when the electroplating solution is consumed to a specified amount, it is necessary to replenish the electroplating solution in the electroplating tank in time. After adding the electroplating solution, the anode activator needs to be added again.

[0003] The existing method of adding is to measure a certain amount of additives on site and then add the measured additives to the electroplating solution. This method of adding is relatively cumbersome and requires manual addition each time, resulting in low production efficiency. After the electroplating solution has been used for a period of time, there will be accumulation of decomposition products of the additives or other impurities. After the impurities come into contact with the auto parts, they will affect the electroplating effect at the bottom of the auto parts. The additives will form deposits after being placed, making the composition uneven. When used, it will cause increased cathode polarization and decreased current efficiency of electroplating of the coating. Both the electroplating solution and the additives contain harmful gases. Long-term inhalation of these harmful substances may also cause long-term effects on the health of the operator. For this reason, we propose a quantitative adding device for electroplating additives for auto parts. Summary of the invention
