Description

Recycling circuit board electronic component scraper

The present invention relates to a circuit board recycling processing device, and more particularly to an electronic component scraping machine for scraping electronic components on a mounted circuit board before pulverizing and recycling the circuit board.

In the existing discarded circuit board, in addition to the circuit board body, there are many types of electronic components, and the materials of the electronic components are separated, for example, plastic, copper, iron, aluminum, graphite, etc. Materials have their respective different values. If the materials can be properly classified and recycled, it is an important issue for resource recycling companies.

When the resource recovery company used to carry out the circuit board recovery, it mainly used the pulverization method to smash the mounted circuit board containing the plurality of electronic components into a plurality of small pieces, and then continued the operation procedures such as classification. As described above, since a plurality of electronic components are mounted on a mounted circuit board, and the material composition is too complicated, if the mounted circuit board is directly pulverized, most of the different materials are mixed together, which is bound to cause subsequent recycling operations. For the difficulties in complication and classification, more processing equipment must be applied to separate and recycle various materials, resulting in high cost of recycling resources.

In order to overcome the difficulty of smashing the above-mentioned circuit board with multiple electronic components and separating various materials, most resource recycling companies currently remove the electronic components on the mounted circuit board, and the remaining circuit boards are only copper. With fiberboard, it can facilitate subsequent recycling. Among them, when the electronic components on the mounted circuit board are removed, some resource recycling companies are mainly manually operated. Pneumatic or electric chisel removes electronic components on the board, but the processing speed is slow and the work efficiency is poor.

Other resource recycling companies use heating to melt the solder soldered on the terminals of the electronic components of the circuit board and remove the electronic components from the circuit board in time. However, this heating operation will cause high pollution during operation. The toxic gas, in order to avoid operator poisoning and environmental hazards, must be used together with expensive exhaust gas treatment equipment, and has high cost of processing equipment and poor work efficiency.

The main purpose of the present invention is to provide an electronic component scraping machine for recycling a circuit board, which is invented to solve the problems of high cost and poor working efficiency of removing and recycling electronic components on a mounted circuit board.
