Abstract

The invention discloses a nitrogen saving system based on a BTU reflow oven and a control method thereof, the nitrogen saving system comprises a PLC control module, a flow valve and a touch screen display, the flow valve is arranged on a nitrogen pipeline to regulate and control the flow of nitrogen, and the PLC control module is respectively connected with the flow valve and the touch screen display to control and regulate the flow valve. According to the nitrogen saving system based on the BTU reflow furnace and the control method of the nitrogen saving system, two nitrogen saving modes are set in the system, so that during normal production, the first nitrogen saving mode is automatically triggered, 25% of nitrogen can be saved, and when no circuit board exists in the BTU due to abnormal production, the second nitrogen saving mode is automatically triggered, and 50 amp can be saved; the nitrogen conveying accuracy and efficiency are improved, the cost is reduced, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of SMT surface mounting assembly line, in particular to a nitrogen saving system based on a BTU reflow furnace and a control method thereof. Background technique [0002] At present, in the process of BTU reflow furnace, when the nitrogen function is enabled in the BTU reflow furnace, the BTU reflow furnace will be quickly filled with nitrogen for half an hour. Fill the BTU with nitrogen. This control method has the following problems: [0003] 1. When there is a circuit board in the BTU reflow furnace, the BTU nitrogen gas is continuously supplied at full load, resulting in too much nitrogen consumption. [0004] 2. When there is no circuit board in the BTU reflow furnace, it is still fully loaded and continuously supplies BTU nitrogen, resulting in waste of nitrogen. Contents of the invention [0005] The technical problem mainly solved by the present invention is to provide a nitrogen saving system b...
