Description

Electronic component scraper for recycling circuit boards

technical field

The invention relates to a recycling and processing equipment for circuit boards, in particular to an electronic component scraper for scraping electronic components on mounted circuit boards in advance before crushing and recycling circuit boards.

Background technique

Existing discarded mounted circuit boards contain not only the circuit board itself, but also various electronic components. Due to the complex composition of the electronic components, such as: plastic, copper, iron, aluminum, graphite, etc., there are different Materials have their corresponding different values. If different materials can be properly classified and recycled, it is an important issue in the current resource recycling industry.

Previously, when the resource recycling industry carried out the recycling of mounted circuit boards, it mainly used shredding means to shred the mounted circuit boards containing multiple electronic components into many fine pieces, and then proceeded with the operation procedures such as classification. As mentioned above, due to the multiple electronic components loaded on the mounted circuit board, there is a problem that the material composition is too complex. If the mounted circuit board is directly crushed, many different materials will be mixed together, which will inevitably lead to subsequent recycling operations. The complexity and difficulty in sorting operations also necessitate the application of more processing equipment to separate and recycle various materials, resulting in high cost of recycling resources.

In order to overcome the aforementioned difficulty of crushing circuit boards with multiple electronic components first, and then separating various materials, most of the current resource recycling industry adopts the method of eradicating the electronic components on the circuit boards first, and the remaining circuit boards are only Copper and fiberboard can be easily recycled later. Among them, when removing the electronic components on the mounted circuit board, some resource recycling businesses mainly use pneumatic chisels or electric chisels to remove the electronic components on the circuit board. However, the processing speed of this operation method is slow and the work efficiency Difference.

Some resource recycling industries use heating to melt the solder on the terminals of the electronic components soldered on the circuit board, and remove the electronic components from the circuit board in time. However, this heating method will produce high pollution during the operation. Toxic gas, in order to avoid poisoning of workers and environmental hazards, must be used together with expensive waste gas treatment equipment, so there are problems such as high cost of treatment equipment and poor operating efficiency.
