Intelligent brazing nitrogen charge monitoring device

Abstract

The invention discloses an intelligent brazing nitrogen charge monitoring device. The intelligent brazing nitrogen charge monitoring device comprises a nitrogen charge tooling, a photoelectric sensor, a micro sensor, a fluid valve, a pressure sensor, a production line emergency stop switch and a controller; the photoelectric sensor, the micro sensor, the fluid valve, the pressure sensor and the production line emergency stop switch are respectively in communication connection with the controller and charge nitrogen according to a control signal sent from the controller; the photoelectric sensor is arranged on the production line between a to-be-machined product and the nitrogen charge tooling; the micro sensor, the fluid valve and the pressure sensor are arranged inside the nitrogen charge tooling. The intelligent brazing nitrogen charge monitoring device achieves monitoring of nitrogen pressure, nitrogen charge time, nitrogen charge times and the nitrogen charge effectiveness during nitrogen charge, improves the nitrogen charge protection reliability and accordingly guarantees the brazing nitrogen charge protection quality.

Description

technical field [0001] The invention relates to the field of automation, in particular to an intelligent monitoring device for brazing nitrogen filling. Background technique [0002] During the brazing process, in order to ensure that there is no scale on the inner surface of the metal at the position of the weld, and to further ensure the cleanliness of the metal pipeline to be welded, it is necessary to pre-fill a certain amount of nitrogen in the inner space of the weldment. [0003] In order to ensure the effect of nitrogen filling protection, nitrogen pressure and nitrogen filling time must be effectively controlled. The traditional nitrogen filling equipment is only a nitrogen pipe. During operation, the nitrogen pipe is directly connected to the metal pipeline to be welded. The relevant parameters of nitrogen filling, such as nitrogen pressure, nitrogen filling time, nitrogen filling times and nitrogen filling effectiveness, etc. Through manual control, effective mon...

AI Technical Summary

Problems solved by technology

The traditional nitrogen filling equipment is only a nitrogen pipe. During operation, the nitrogen pipe is directly connected to the metal pipeline to be welded. The relevant parameters of nitrogen filling, such as nitrogen pressure, nitrogen filling time, nitrogen filling times and nitrogen filling effectiveness, etc. Through manual control, effective monitoring cannot be realized, and the reliability and consistency of nitrogen filling protection are difficult to effectively guarantee

Therefore, there are serious hidden dangers in the cleanliness of the system inside the pipeline. The accumulation of impurities in the system will cause the system to be dirty and block, which will affect the system performance of the product.
