[0002] Etching solution is a raw material used for copperplate engraving. It is a liquid that engraves by eroding the material. Theoretically, any reagent that can oxidize copper to form soluble copper salts can be used to etch copper-clad laminates. However, considering the damage to the anti-corrosion layer, etching rate, etching coefficient, copper dissolution capacity, solution regeneration and copper recovery, environmental protection, and economic benefits, there are six types of etching solutions currently in use: acidic copper chloride, alkaline copper chloride, ferric chloride, ammonium persulfate, sulfuric acid / chromic acid, and sulfuric acid / hydrogen peroxide etching solution.

[0003] In the prior art, the temperature of the etching solution needs to be controlled during processing and preparation, and it needs to be controlled between 45-55℃. However, the existing devices are inconvenient to monitor and adjust the temperature, and cannot guarantee that the internal temperature of the device is controlled within a suitable range. Therefore, an automatic monitoring and adjustment device for acid etching solution parameters is proposed to solve the above problems. Utility Model Content

A heating base is installed inside the extension frame, and the output end of the heating base contacts the lower surface of the heat-conducting plate. One end of the heating base extends to the outside of the extension frame, and a base plate is welded to the lower surface of the heating base. Two opposite surfaces inside the extension frame are provided with mating grooves, and two mating plates are welded to the upper surface of the base plate.

[0006] Furthermore, the position of the docking plate corresponds to the position of the docking groove, the two docking plates are slidably connected to the docking groove, and a docking hole is opened on one surface of each of the two docking plates.

[0007] Furthermore, each of the two mating grooves has a through hole on one inner surface, the through hole penetrating the periphery of the extension frame, and the position of the through hole corresponds to the position inside the mating hole.

[0008] Furthermore, a docking rod is slidably installed inside each of the two through holes, with one end of each docking rod extending through the through hole into the docking hole, and the two docking rods being slidably connected to the docking hole.

[0009] Furthermore, the inner wall of the inner barrel is provided with an internal thread, and a top cover is installed on the upper surface of the outer barrel, with the connecting end of the top cover being screwed and fixed to the inner barrel.
