On-line concentration detection and dosing integrated device for electroplating bath solution

Abstract

The invention discloses an electroplating bath solution concentration online detection and charging integrated device used in cooperation with an electroplating online bath. The electroplating bath solution concentration online detection and charging integrated device comprises a housing, and the housing is provided with a sampling water inlet, a sampling water return opening and a chemical inlet. The sampling water inlet is connected with the electroplating online bath through an outer sampling water inlet pipe. The electroplating bath solution concentration online detection and charging integrated device further comprises a sampling pump arranged on the outer sampling water inlet pipe. A cooling unit, a concentration detection unit, an automatic chemical charging unit and a programmable logic controller (PLC) are arranged in the housing. The sampling pump is used for feeding a bath solution in the electroplating online bath into the cooling unit. The cooling unit, the concentration detection unit and the automatic chemical charging unit are controlled by the PLC to complete cooling and concentration detection on the sampled bath solution automatically, and the chemical is charged into the electroplating online bath according to the charging amount obtained through calculation. The device can replace manpower and has quite high control precision and working efficiency.

Description

technical field [0001] The invention relates to an integrated device for online concentration detection and dosing of electroplating bath liquid. Background technique [0002] At present, due to the continuous loss of components in the electroplating line tank during electroplating, it is necessary to add chemicals to the tank in time to ensure that the concentration in the tank can always be kept within the preset concentration range. Therefore, in the electroplating industry, the accuracy of the control of the concentration of the components in the wire tank is directly related to the quality of the electroplating. [0003] The traditional method is to extract the bath liquid in the electroplating line tank in real time manually or with the help of a sampling pump and transfer it to other places for cooling, then use an instrument to measure the concentration of the single component in it, and then calculate the required single-component dosing by computer Quantity, and f...

[0003] The traditional method is to extract the bath liquid in the electroplating line tank in real time manually or with the help of a sampling pump and transfer it to other places for cooling, then use an instrument to measure the concentration of the single component in it, and then calculate the required single-component dosing by computer Quantity, and finally add the medicine manually, the process is cumbersome and the cycle is long, it is time-consuming and laborious for the workers, and increases the labor cost for the enterprise

And because the bath concentration detection and dosing are two independent processes, the interval between them is long, which will inevitably cause errors and omissions
