Description

Technical Field

[0001] The invention relates to the technical field of lens production, and in particular to a lens disassembling machine. Background Art

[0002] As more and more lens barrels are made of plastic materials and the lenses are fixed by hot-melt process, but the lens barrel with poor hot-melt process will be damaged when disassembled, there are currently two disassembly methods: 1. Knock it out from the other end of the lens to remove the lens; 2. Use a soldering iron to melt 3 slits in the lens barrel, and then cut the plastic to remove the lens. Both methods will cause serious damage to the lens, especially when the lens barrel material is relatively hard and cannot be knocked out, and the soldering iron is very hard after melting and difficult to cut, resulting in the lens being unable to be taken out. In addition, these two methods are inefficient and cannot meet production needs. Summary of the invention
