Problems solved by technology

However, the method of manual liquid addition is not only frequent and labor-intensive, which increases labor costs, but also easily causes human errors, and even easy to cause missed additions caused by human factors; although the quantitative addition of motors has achieved automation, but When the liquid pump is used for a long time, there will be a large deviation in the flow rate of the liquid pump, and the deviation is not easy to be found

Abstract

The invention provides a liquid constant-volume automatic adding system to achieve the goals of automatic liquid adding and stable adding amount of liquid. The liquid constant-volume automatic addingsystem comprises a liquid source, a container provided with a liquid-outlet pipeline at the bottom, a liquid-inlet pipeline, a siphoning pipeline and a control device, the liquid-outlet pipeline is provided with a first control valve, the liquid-inlet pipeline is provided with a liquid pump, the control device comprises a liquid level detection device and a controller, and the controller controlsthe liquid pump to add the liquid to the container according to a detection value of the liquid level detection device until the liquid reaches a first preset liquid level. When the liquid in the container reaches the first preset liquid level, the siphoning pipeline can siphon the liquid in the container to the outside of the container to enable the liquid in the container to reach a second preset liquid level in a constant-volume manner; and when the liquid level detection device detects that the liquid in the container reaches the second preset liquid level in the constant-volume manner, the controller controls the first control valve to release the liquid.

Description

technical field [0001] The invention relates to the technical field of circuit board manufacturing, in particular to an automatic adding system for constant volume of liquid medicine. 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 circuit boards, chemical solutions are required to clean or / and etch them, and there are certain requirements for the concentration of chemical solutions for cleaning or / and etching to increase product yield and maintain quality. However, in the process of cleaning or / and etching, as the production continues, the concentration of the chemical solution will gradually decrease. When the concentration of ...
