[0002] The existing photovoltaic glass coating production process adopts the roller coating method, and its working principle is to mix the AR coating liquid and the diluent first and then supply them to the coating machine. A compensation device is disclosed in Chinese patent CN202766416U, and particularly relates to a real-time concentration compensation device for glass liquid phase coating production. The AR coating liquid stock barrel is injected into the liquid supply barrel through the injection supply pump, and the liquid supply barrel is connected to the roller coater by using the liquid supply pump. The AR coating liquid reflux groove in the roller coater is injected into the mixing detection barrel, and the mixing detection barrel is connected to the automatic detection replenishment machine through the AR coating liquid inlet supply pump, and the diluent barrel is connected to the automatic detection replenishment machine through the diluent outlet supply pump, and the mixing detection barrel is connected to the automatic detection replenishment machine through the diluent outlet supply pump, and the mixing detection barrel is connected to the automatic detection replenishment machine through the diluent outlet supply pump, and the liquid supply barrel is connected to the automatic detection replenishment machine through the AR coating liquid outlet supply pump.

[0003] The concentration monitoring of this system requires that the liquid refluxed from the coating machine and the diluent be sent into a mixed detection barrel. After the detection is completed, a certain amount of diluent is added to the liquid supply barrel through proportioning and then mixed with the original liquid. This process is time-consuming and the real-time performance is not high enough. Utility Model Content

[0004] The purpose of the utility model is to provide a concentration compensation device for photovoltaic glass coating production. By designing an automatic detection and replenishment device, the concentration of the mixed liquid is controlled and adjusted so that the real-time concentration can be compensated, while shortening the liquid proportioning time and improving the real-time performance.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a concentration compensation device for photovoltaic glass coating production, comprising an AR stock liquid barrel, a coating machine, a diluent barrel and a liquid supply barrel, a stock liquid supply pipe is connected between the AR stock liquid barrel and the liquid supply barrel, a diluent liquid supply pipe is connected between the diluent barrel and the liquid supply barrel, an automatic detection and replenishing machine and a return pipe are respectively connected to the top of the liquid supply barrel, an AR coating liquid reflux groove is provided at one end of the coating machine, one end of the return pipe is connected to the AR coating liquid reflux groove, a mixed coating liquid supply pipe is connected between the liquid supply barrel and the coating machine, and liquid supply pumps are installed in the pipelines of the stock liquid supply pipe, the diluent supply pipe, the return pipe and the mixed coating liquid supply pipe.

[0006] Preferably, the bottom of the AR coating liquid reflux groove is arranged in an inverted trapezoidal shape, and the liquid return pipe is connected to the bottom of the AR coating liquid reflux groove.

[0007] Preferably, a stirring unit is installed in the liquid supply barrel, and liquid supply valves are installed in the pipelines of the original liquid supply pipe, the diluent supply pipe, the return pipe and the mixed coating liquid supply pipe.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] The utility model uses a liquid supply barrel to replace the original mixing barrel, connects the return pipe to the liquid supply barrel, makes the AR coating liquid flow back into the liquid supply barrel filled with the original liquid, automatically detects the supplementer to directly measure and compare the mixed liquid mixed with the return liquid, and makes the diluent continue to enter the liquid supply barrel through the diluent liquid supply pipe until the diluent is supplemented to the set standard, then the diluent supplement is stopped, and real-time detection is performed while supplementing. This method does not require the original liquid and the return liquid to be mixed and proportioned in the mixing barrel and then the diluent is supplemented by the automatic detection supplementer. The diluent can be directly input into the liquid supply barrel and measured at the same time, thus shortening the proportioning time and reducing the investment in equipment.
