Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of electronic component recycling, in particular to a waste electronic component recycling device. BACKGROUND

[0002] Electronic components are the components of electronic elements and small and medium-sized machines and instruments, which are usually composed of several parts and can be used in similar products. They are commonly used in some parts of the electrical, radio, and instrument industries, such as capacitors, transistors, hairsprings, and spring electronic devices. Electronic components include resistors, capacitors, inductors, potentiometers, tubes, heat sinks, mechanical and electrical components, connectors, etc. Most of the waste electronic components contain precious metals, so electronic components need to be recycled after excessive use. When recycling circuit boards, the resistors and capacitors on the circuit board need to be separated, and then the circuit board is further processed.

[0003] A patent application with publication number CN117600203B discloses a waste electronic component recycling device and method. By setting a first conveyor belt, a cutting blade, and a feeding slot, the parts of the waste electronic components that cannot be recycled are placed on the first conveyor belt. The first conveyor belt and the second conveyor belt clamp the electronic components, and the first motor drives the first conveyor belt to transport the electronic components. At the same time, the second motor drives the output end cutting blade to rotate and cut the continuously transported electronic components. The cut electronic components, the recyclable parts, slide through the feeding slot and the discharge plate to the inside of the pretreatment device, while the non-recyclable parts slide through the discharge slot and are collected, allowing the electronic components to be screened before recycling.

[0004] In the prior art, since the circuit board has many resistors, capacitors, and other components installed on its upper end, the resistors, capacitors, and other components are removed in advance, and the crushing and sorting equipment can more efficiently process the circuit board. When processing the resistors, capacitors, and other components on the surface of the larger circuit board, the resistors, capacitors, and other components are usually welded on the upper end of the circuit board by soldering. Generally, a hot air gun is used to melt the solder and manually remove the resistors, capacitors, and other components. The efficiency is low. If the resistors, capacitors, and other components on the surface of the circuit board are forcibly removed, it will cause damage to the circuit board. Since the circuit board contains heavy metals such as lead, mercury, and cadmium, violent disassembly will cause these substances to be directly exposed to the environment.
