[0019] The following is a further detailed description of the specific implementation methods of the present invention, such as the shapes and structures of the components involved, the relative positions and connection relationships between the components, the functions and working principles of the components, the manufacturing process and the operation and use methods, etc., through the description of the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.

[0020] like Figure 1As shown, in the spray production line, the spray chamber 4 is used for etching operations, and the liquid medicine tank 1 stores HF acid liquid; the acid inlet pipeline 2 transports HF, the heating device 3 heats the HF acid liquid to the production temperature, and the acid return pipeline 5 recovers HF. One end of the acid inlet pipeline 2 is connected to the inlet of the spray chamber 4, and the other end is connected to the outlet of the liquid medicine tank 1. The outlet of the spray chamber 4 is connected to the inlet of the liquid medicine tank 1 via the acid return pipeline. The heating device 3 is connected in series to the acid inlet pipeline 2, and the heating device 3 is as close to the spray chamber 4 as possible to reduce the heat dissipation of the pipeline between the heating device 3 and the spray chamber 4, and to cause fluctuations in the temperature of the acid liquid input into the spray chamber 4. An insulation layer can also be wrapped around the acid inlet pipeline 2 between the heating device 3 and the spray chamber 4.

[0021] The heating device 3 has an inner tank, which preferably adopts a polytetrafluoroethylene inner tank 10, and has an overall cylindrical structure. The inner tank is a sealed cavity, and is connected to a hot water pipe 6 and a condensed water pipe 7. Hot water is circulated and injected into the inner tank through the hot water pipe 6 and the condensed water pipe 7 to maintain the hot water temperature in the inner tank within a constant range. The acid liquid is heated by a water bath. An acid liquid pipe is provided in the inner tank, and the acid liquid pipe is arranged in a coiled manner in the inner tank to increase the contact area with the hot water and the release time. The hot water pipe 6 heats the HF acid with hot water, and the condensed water pipe 7 cools the HF acid with cold water to balance the temperature. The problem in the inner tank is adjusted by independently heating water and cold water, so that the temperature adjustment is faster. The hot water pipe 6 and the condensed water pipe 7 are connected to a hot water circulation system, and the hot water circulation system provides circulating hot and cold water for the inner tank.

[0022] In order to provide the device with intelligence and reliability in heating the acid liquid, at least one thermometer 8 is provided in the inner tank, and the thermometer 8 monitors the HF acid heating temperature; preferably, multiple thermometers 8 are evenly arranged in the inner tank, and a multi-point collection method is adopted to make the temperature data more real and reliable. All thermometers 8 are connected and output temperature signals to the hot water circulation system as signal feedback, and the hot and cold water supply of the hot water pipe 6 and the condensed water pipe 7 is adjusted by the feedback temperature.

[0023] There are two hot water pipes 6 and two condensed water pipes 7 connected to the hot water circulation system, and each of the four corners of the inner tank is provided with a pipe interface, one group of diagonal pipe interfaces is connected to the hot water pipe 6, and the other group of diagonal pipe interfaces is connected to the condensed water pipe 7. The cross-arrangement can make the cold and hot water merge faster and balance the temperature in the inner tank faster.

[0024] In order to allow the acid liquid pipeline to join the circulation, the liquid inlet and liquid outlet of the acid liquid pipeline are connected in series on the acid inlet pipeline 2. The liquid inlet and liquid outlet are preferably set at the center position of the circle at both ends of the inner tank. A PVC shell 9 is provided outside the inner tank. The PVC shell 9 protects the inner tank and prevents liquid leakage. The double protection is safer and more reliable. The PVC shell 9 is a sealed cavity wrapped outside the inner tank. Insulating material can also be filled between the inner tank and the PVC shell 9 to reduce the energy consumption of the inner tank and the ability to maintain a constant temperature.

[0025] The hot water pipe 6 of the device is spirally wound in the PTFE inner liner through the hot water inlet and then drawn out from the hot water outlet. The condensed water pipe 7 is spirally wound in the PTFE inner liner through the condensed water inlet and then drawn out from the condensed water outlet. The thermometer 8 is connected to the PTFE inner liner. The heating device 3 is connected in series between the liquid medicine tank 1 and the spray chamber 4 through the acid inlet pipe 2 and is close to the spray chamber 4. Then, high-temperature hot water is introduced through the hot water pipe 6 to heat HF ​​acid, so that the temperature of the spray acid liquid meets the mass production requirements.

[0026] This device can be directly connected in series to the acid inlet pipe 2 of the spray chamber 4, avoiding the problem that the liquid medicine box 1 is not resistant to high temperatures, and directly enters the spray chamber 4 for acid etching after heating, and can maximize the heating effect, so that the HF acid in the spray chamber 4 reaches the mass production temperature requirement.

[0027] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
