Description
Technical Field
The invention relates to a system and a method for automatically adding a brightener into a rolling and plating solution.
Background
During the production process of the parts, it is often necessary to electroplate them. The electroplating process of some small parts is inconvenient to operate independently, so that the electroplating process is generally carried out by putting a large number of small parts in a rolling container (roller). This process is called barrel plating, and the plating solution used for barrel plating is the barrel plating solution of the present invention. In the barrel plating process, in order to improve the texture of the appearance of parts and make the plating level and smooth, a brightener is often added into the barrel plating solution. The existing common method for adding the brightener comprises the following steps: (1) in the barrel plating process, after a roller product is fed into a plating tank, a certain amount of brightener is measured by a manual measuring tool and added to the liquid level close to the roller. (2) Converting into a certain amount of brightening agent according to the ampere hour amount of each plating bath during plating, and quantitatively adding the brightening agent at a fixed position point of the plating bath through a metering pump at fixed time, wherein each plating bath needs a set of device for adding the brightening agent. (3) A set of device for adding the brightening agent is matched with a plurality of electromagnetic valves (matched with the number of rollers or plating tanks) and pipelines for use, and the electromagnetic valves at corresponding positions are opened for quantitative addition once every time a roller product is fed. The above-mentioned methods have the following disadvantages: (1) the effect is optimal when the coating is added manually, the added coating area is large, the coating can be quickly dispersed into the plating solution, and the coating can exert the effect in time when being close to a product newly entering the plating solution; however, the labor intensity of the operator is high, and the error of manual measurement is large, which is not favorable for high-requirement control. (2) The two automatic adding methods have a common defect, the fixed-point adding is not beneficial to dispersion, and the fixed-point adding can be dispersed into the plating solution only by circular filtration; the effect of the brightener cannot be exerted in time for products far from the addition point. This automatic addition method is not very suitable in barrel plating and is costly.
Therefore, it is necessary to improve the method of adding brightener to the rolling bath to ensure the accuracy of the amount of brightener added and the dispersing effect, while reducing the cost of investment.
