Embodiment

[0036] Referring to Fig. 1, after the circuit board 16 to be disassembled is clamped and fixed, it is transported to the preheating device 2 by the clamping and conveying mechanism 7 through the entrance 1 of the heat preservation chamber, and the whole is heated by the combination of the resistance wire or the infrared heating plate in the preheating device 2 and the hot air. Preheat the circuit board to 140~180°C

[0037] The preheated circuit board 16 can be sent to the heating device 3 to heat the circuit board 16 . The heating device 3 is composed of a solder melting tank 30 placed below the clamping and conveying mechanism 7. The molten solder 4 in the solder melting tank 30 is in contact with the soldering surface of the circuit board 16, and the soldering surface of the circuit board 16 is heated until the solder melts. If after entering the desoldering device below, the temperature of the high-temperature and high-pressure gas is high enough and the running speed of t...

Abstract

The invention relates to an electronic waste recycling technology, in particular to equipment which disassembles components and separates soldering flux from a circuit board. The invention discloses disassembling equipment for circuit board components. The technical proposal adopted by the invention is that the disassembling equipment for the circuit board components comprises desoldering equipment consisting of a slit nozzle used for injecting high-temperature and high-pressure gas to the circuit board so as to lead the soldering flux to be separated from the circuit board; and the disassembling equipment is characterized in that the slit width of the slit nozzle is more than 0.8mm and less than or equal to 2mm. The disassembling equipment is used for disassembling waste circuit boards, can reduce the energy consumption and improve the efficiency.

Description

technical field [0001] The invention relates to the recycling technology of electronic waste, in particular to a method and device for disassembling components and separating solder from a circuit board. Background technique [0002] The circuit board is generally a printed circuit board (Printed Circuit Board, referred to as PCB). Commonly referred to as a circuit board, it is mainly composed of components, printed circuit board substrates, and solder connecting components and printed circuit board substrates. It is the most basic and important component of electronic and electrical equipment such as televisions, air conditioners, computers, monitors, and fax machines. part. In recent years, electronic and electrical equipment, especially consumer electronic products, have developed rapidly and are frequently updated. More and more electronic and electrical equipment are discarded due to the end of their service life or replacement. As an important part of electronic and ...
