Waste display dismantle sorting system for recycling and dismantle sorting method using same {DISMANTLING AND SORTING SYSTEM OF WASTED DISPLAY DEVICE FOR RECYCLING, DISMANTLING AND SORTING METHOD USING THE SYSTEM}

The present invention relates to an integrated system for effectively disassembling to recycle display device waste such as televisions, monitors, and the like.

At present, various efforts are being made to recycle resources in various fields. In particular, in the case of electronic products, there are many expensive metal, non-metal, and semiconductor parts that can be reused, and thus a necessity for systematic dismantling sorting for recycling is on the rise.

Korean Patent Laid-Open Publication No. 10-2013-0020651 discloses a process for removing harmful substances from LCD displays, but the separation process for recycled materials is still being carried out manually by disassembling such as televisions and monitors. Since it is not maintained, the productivity difference between skilled and unskilled workers is remarkable.

In other words, in a typical recycling center, the collected display is picked up by a worker and moved to a workbench, and then dismantled / separated at random without a systematic work manual, which causes unskilled workers to work without being fully informed or aware of the work that requires attention. In addition, safety issues may occur when handling hazardous materials.

In addition, since the collectors randomly sort by plastic, metal, etc. without classification by composition and class, the post-processing of sorting and sorting should be performed later, resulting in low productivity and not high separation rate by class compared to time-cost input. There is this.

In this regard, the application for the decomposition device for automatically identifying the decomposition target and transmitting information on the decomposition target such as a process manual required for each worker in the original space has been in progress (Korea Patent Publication No. 10-2016-0095493). There was a disadvantage in that the processing speed of the entire system is slowed down by the processing speed difference according to the skill of the. In addition, there is a problem that the operator may be exposed to mercury in the process of processing the CCFL used in the backlight of the display.
