Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of waste household appliances treatment, and in particular to a production line for precise disassembly of small household appliances. Background Art
[0002] Small household appliances refer to small household appliances used for daily life other than traditional refrigerators, air conditioners, washing machines, televisions, and computers, including printers, telephones, rice cookers, hair dryers, induction cookers, electric fans and many other household appliances.
[0003] The main components of small household appliances include structural parts and non-structural parts. Structural parts mainly include plastic, metal, rubber and other structural parts; non-structural parts mainly include circuit board control parts, heating plates, motors, switches, plugs, etc. The parts disassembled from small household appliances are divided into qualified parts and unqualified parts. Qualified parts are parts without obvious damage, and unqualified parts are parts that are obviously damaged or detected to be damaged.
[0004] Discarded small household appliances contain many valuable materials, such as copper, aluminum, iron, steel, and plastics. In addition, they also include many parts that can be reused after testing. These resources are not reused, or are used in a low-end broken way, resulting in a waste of resources. The current dismantling of discarded small household appliances has the following disadvantages: (1) low work efficiency; (2) poor sorting quality. Due to the different materials used in discarded small household appliances, different types of the same material can often be obtained after dismantling. For example, steel has types such as 202 steel and 304 steel. When recycling, they are often recycled in a unified manner according to the low-cost type; (3) low resource utilization of parts. Since it is impossible to achieve fine classification of the parts obtained after dismantling small household appliances, the high-value recovery rate of discarded small household appliance parts is low and the recycling cost is high.

[0021] During operation, the small household appliances to be disassembled are first placed on the feed conveyor belt 4, and then the feed conveyor belt 4 transports the small household appliances to be disassembled to the sorting conveyor belt 3. In the process of the sorting conveyor belt 3 transporting the small household appliances to be disassembled, the staff takes the small household appliances to be disassembled from the sorting conveyor belt 3 next to the disassembly workbench 9 and places them on the disassembly workbench 9 for disassembly. The accessories of the household appliances after disassembly mainly include: structural components such as plastic, metal, and rubber, as well as non-structural components such as circuit board control components, heating plates, motors, switches, and plugs; it is inevitable that there are obvious damages or unqualified accessories detected in the structural and non-structural components;
[0022] For unqualified parts: the staff will put the unqualified parts obtained after disassembly into the unqualified parts drop-out port 11 on the disassembly workbench 9. The unqualified parts discharged from the unqualified parts drop-out port 11 will fall on the unqualified parts conveyor belt 14, and then be discharged from the unqualified parts conveyor belt 14 and then be centrally packaged or processed;
[0023] For qualified structural components: the staff will put the qualified structural components obtained after disassembly into the structural component drop-out port 10 on the disassembly workbench 9, and the qualified structural components output from the structural component drop-out port 10 will fall on the structural component sorting conveyor belt 13, and then be transported to the structural component transition conveyor belt 20 via the structural component sorting conveyor belt 13, and then be transported to the structural component sorting conveyor belt 15 via the structural component transition conveyor belt 20, and then be transported to the discharging conveyor belt 16 via the structural component sorting conveyor belt 15.

[0024] For qualified non-structural components such as circuit board control components, heating plates, motors, switches, and plugs: the staff will classify the qualified non-structural components obtained after disassembly and place them in different turnover boxes. Then, the code printer 12 will mark the corresponding identification code on each turnover box. Then, the parts conveyor belt 6 will transport the coded turnover boxes with the classified non-structural components to the parts inspection conveyor belt 8. Then, the parts inspection conveyor belt 8 will transport them to the intelligent vertical warehouse 7. The intelligent vertical warehouse 7 will then automatically store the input coded turnover boxes.
[0025] For small household appliances that are not disassembled in time: During the process of disassembling small household appliances by the staff, the small household appliances to be disassembled on the sorting conveyor belt 3 that have not been taken away by the staff in time will enter the second circulation conveyor belt 52, and then be transported to the first circulation conveyor belt 51 via the second circulation conveyor belt 52, and then be transported to the third circulation conveyor belt 53 via the first circulation conveyor belt 51, and then be transported back to the feed conveyor belt 4 via the third circulation conveyor belt 53, and then be transported back to the sorting conveyor belt 3 by the feed conveyor belt 4 for manual take-up and disassembly.
