Method and apparatus for separating component pins and soldering tin of circuit board

Abstract

The invention discloses a disengaging method of architrave and mischzinn of a circuit board element and a device thereof. A metallic mesh-shaped conveyor belt is mounted on the frame; a heating device is installed below the conveyor belt; a circuit board is fed in from the front end of the conveyor belt and is transferred by the conveyor belt to the position above the heating device for continuous heating, and during the process, some of the architrave and the circuit board are disengaged automatically and fall into a receiving basin below the conveyor belt; at the same time, harmful gases produced in the heating process are exhausted by an exhaust pipe and are discharged into the air after the deodorization treatment; a vibration device and a recovery device are installed and connected to the position below a rear roller of the conveyor belt; a vibrating grid vibrates at high frequency, and the molten mischzinn and the architrave on the circuit board fall off with the function of the vibration and fall into a recovery container. The heating method of the invention is capable of completely removing and recovering the tin and the mischzinn, the method is simple, practical and efficient, and effectively protects the air from contamination, thereby the method is environment friendly.

Description

Technical field: [0001] The invention relates to the technical field of environmental protection, in particular to a method and equipment for removing solder from circuit board component feet. Background technique: [0002] With the modernization of industrial and agricultural production and the advancement of science and technology, especially the rapid development of information technology, the replacement of electronic products is more frequent, followed by the accumulation of eliminated and scrapped electronic circuit boards, which seriously affects and destroys the ecology. environment. At present, the treatment of waste electronic circuit boards is still a major problem in the world, such as landfill, washing, incineration and other methods. The metals and polymer organics are difficult to degrade under natural conditions, and harmful components pass through water, air, Soil enters the environment where people live, causing potential, long-term, and irreversible harm ...
