Defective lens disassembling structure and using method thereof

Abstract

The invention relates to a defective lens disassembling structure, which is characterized by including a disassembling head for cutting off a fuse surface of a lens and a lens barrel. The tail end of the disassembling head is a sharp wedged surface. A press block for pressing the lens is disposed inside the disassembling head. An elastic element between the press block and the disassembling head drives to vertically press the lens to move in a reciprocating manner. A cavity A for accommodating the press block is arranged at the bottom inside the disassembling head, a cavity B is arranged at the top inside the disassembling head, and a vertically-extending cylindrical through hole is formed between the cavity A and the cavity B. A guide rod for vertically sliding in the cylindrical through hole is arranged in the cylindrical through hole in a coaxial manner. The top of the guide rod is in threaded connection with a guide block in the cavity B. The defective lens disassembling structure has a simple structure, solves difficulties in disassembling the lens barrel, saves people the trouble of discarding detective lens barrels and lenses, and enables a lens discarding rate to be low. The lens can be knocked out slightly as long as the fuse surface of the lens and the lens barrel is cut off.

Description

technical field [0001] The invention relates to a structure for dismantling a defective lens and a method for using the same. Background technique [0002] As more and more lens barrels are made of plastic materials, and the lens is fixed by hot-melt process, but the dismantling of the lens barrel with poor heat-melt will cause the lens to be damaged; currently, there are two dismantling methods: 1. From the lens to the other Tap one end to take out the lens; 2. Use an electric soldering iron to melt 3 slits in the lens barrel, then cut the plastic and take out the lens. But both of these will cause serious damage, especially if the material of the lens barrel is relatively hard, it cannot be knocked out by knocking, and the electric soldering iron is very hard and difficult to cut, resulting in the lens cannot be taken out. Contents of the invention [0003] The object of the present invention is to provide a structure for dismantling a defective lens and a method for us...

Problems solved by technology

But both of these will cause serious damage, especially when the material of the lens barrel is relatively hard. It cannot be knocked out by knocking. After the electric soldering iron is melted, it is very hard and difficult to cut, resulting in the lens cannot be taken out.
