Abstract

The present invention provides a solution automatic addition system. The objective of the invention is to achieve automation liquid adding and addition stabilization of an antifoaming agent. The solution automatic addition system comprises a liquid medicine addition device, an antifoaming agent addition device and a control device. The liquid medicine addition device comprises a liquid medicine source, a container provided with a liquid outlet pipeline, a liquid inlet pipeline and a siphon pipeline; the liquid outlet pipeline is provided with a first control valve, and the liquid inlet pipeline is provided with a liquid pump; the antifoaming agent addition device comprises an antifoaming agent source and a delivery line; the delivery line is provided with a second control valve and a flowcontrol valve; the control device comprises a liquid level detection device and a controller; the controller controls opening and closing of the second control valve and controls the liquid valve to add liquid in the container according to the liquid level detection device, after the liquid medicine in the container reaches a first preset liquid level, the siphon pipeline can siphon the liquid medicine in the container to the outer portion of the container, and when the liquid level detection device detects that the volume of the liquid medicine in the container is adjusted to a second presetliquid level, the controller controls the first control valve to release the liquid medicine.

Description

technical field [0001] The invention relates to the technical field of etching line development and film removal in the inner layer of circuit boards, and in particular relates to an automatic solution adding system. Background technique [0002] Printed Circuit Board (PCB) is a product that is designed and produced with circuit graphics on the substrate by printing. It is the basis of almost any electronic product. With the rapid development of the electronic industry, printed circuit boards, as the basic components of electronic products, are more and more widely used. [0003] In the production process of etching line development and stripping the inner layer of circuit boards, chemical solutions are needed for etching and film stripping. There are certain requirements for the concentration of chemical solutions for etching and film stripping to increase product yield and maintain quality. However, in the process of etching and stripping, as the production continues, the...
