Heating the acid etching solution in the acid etching solution supply device to 60-80 ℃, then flowing into the acid etching tank 100, putting the workpiece to be subjected to acid etching into the acid etching tank 100, taking out the workpiece after specified acid etching for a certain time, washing away the acid solution remained on the workpiece through the workpiece cleaning pool 200, and then carrying out the next tissue inspection.
The microwave heating has the advantages of high temperature rising speed, high heating efficiency, great energy consumption saving and production cost reduction;
the microwave heating device 400, the acid etching solution supply device and the acid etching tank 100 are all independent equipment units, and the charged elements and circuits in the thermal acid etching device are not directly contacted with the acid etching solution, so that the device is not corroded by the acid etching solution;
the microwave heating device 400 does not directly heat the acid etching solution in the acid etching tank 100, but heats the acid etching solution in the acid etching solution supply device and then flows into the acid etching tank 100, so that the potential safety hazard that the workpiece of the existing equipment is directly contacted with and heats the acid etching solution and can explode is solved, and the safety is high.
Further, the acid etching solution supply device includes a constant temperature tank 310 and a heating pipe 320, the heating pipe 320 is disposed in a microwave heating field of the microwave heating device 400, a liquid inlet and a liquid outlet of the heating pipe 320 are communicated with the constant temperature tank 310 through a first circulation pipeline 910, and the constant temperature tank 310 is communicated with the acid etching tank 100 through a second circulation pipeline 920.
The acid etching solution supply device of the present invention may also adopt other manners, such as directly selecting the constant temperature bath 310, wherein the constant temperature bath 310 is made of a material that is transparent to waves, and the microwaves generated by the microwave heating device 400 directly act on the acid etching solution in the constant temperature bath 310.
When the thermal acid etching device works, the delivery pump device of the first circulation pipeline 910 is started, the acid etching liquid in the thermostatic bath 310 enters the heating pipe 320 along the first circulation pipeline 910, the microwave field generated by the microwave heating device 400 is used for heating the acid etching liquid in the heating pipe 320, and the heated acid etching liquid flows into the thermostatic bath 310 again, the thermostatic bath 310 maintains a relatively sealed environment, so that heat loss is reduced, and the temperature of the acid etching liquid in the thermostatic bath 310 is ensured to be maintained in a relatively stable range.
After the acid etching solution in the constant temperature tank 310 reaches the set temperature (60-80 ℃), the delivery pump of the second circulation pipeline 920 is opened, and the acid etching solution in the constant temperature tank 310 is delivered to the acid etching tank 100. The acid liquor in the acid etching tank 100 and the constant temperature tank 310 is in a continuous circulation and exchange process, so that the condition that the temperature of the acid etching liquor in the acid etching tank 100 is reduced due to heat loss is continuously supplemented; and continuously replenishing the acid solution consumed by the acid etching tank 100 to ensure that the acid solution has sufficient acid solution concentration.

Therefore, the temperature of the etching solution in the etching solution tank 100 and the constant temperature tank 310 is continuously decreased. When the thermocouple 610 detects that the temperature in the thermostatic bath 310 is lower than the set temperature, it feeds back to the controller.

It should be noted that, since the acid etching tank 100 is of an open design, it is not suitable to provide the thermocouple 610 and the pH meter 620 in the acid etching tank 100.
Meanwhile, as the acid etching process is performed, the acid solution in the acid etching tank 100 is continuously consumed, the concentration of the acid etching solution is continuously reduced, and when the pH meter 620 monitors that the concentration of the acid etching solution is lower than a set concentration threshold, the controller is fed back to control the acid solution supplementing device 630 to supplement the acid solution into the constant temperature tank 310, so that the consumed acid solution in the acid etching solution is supplemented, the concentration of the acid solution is increased, and the acid solution in the acid etching tank is ensured to be kept in a reasonable range.
