Abstract

An automatic sorting method for waste circuit board components comprises the following steps that a mixture of the waste circuit board components is divided into two fractions of +25 mm and -25 mm through an automatic fractionating device; slots, sockets and chips of the fraction of +25 mm are sorted through the shape sorting function and the color sorting function of a crawler-type color sorter;and slots, chips, capacitors, resistors, transistors and indicator lamps of the fraction of -25 mm are sorted through the shape sorting function and the color sorting function of a chute-type color sorter. According to the automatic sorting method, photoelectric sorting is adopted, the different circuit board components are automatically, efficiently and accurately sorted, and the sorting efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the field of environmental protection treatment of hazardous solid waste and resource regeneration, and relates to an automatic sorting method for discarded and dismantled components. Background technique [0002] Components on discarded circuit boards mainly include chips, capacitors, resistors, transistors, inductors, optocouplers, transformers, and connectors. Although the discarded circuit board as a whole has lost its original function, many electronic components on it are far from reaching their service life. By testing high-value components, those with good performance can be directly reused to increase the value of resources. ; Then classify other common components and components containing toxic and harmful substances, and classify and recycle components of the same or similar materials, which can effectively improve the separation efficiency and material utilization of various metals and toxic and harmful substances. ...
