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.

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] Such as figure 1 As shown, a defective lens dismantling structure includes a dismantling head 1 for cutting off the fused surface of the lens and the lens barrel, the end of the dismantling head is a sharp wedge-shaped surface 2, and the dismantling head A pressing block 3 for pressing the lens is arranged inside, and the movement between the pressing block and the dismantling head is driven by an elastic element to reciprocate and squeeze the lens vertically.

[0021] In this embodiment, the inner bottom of the disassembly head is provided with a cavity A4 for accommodating the briquetting block, the inner top of the disassembly head is provided with a cavity B5, and the cavity A and the cavity B are A cylindrical port 6 extending vertically is provided.

[0022] In this embodiment, a guide rod 7 for vertically sliding on the cylindri...

Abstract

The invention relates to a defective lens dismantling structure, which is characterized in that it includes a dismantling head for cutting off the fused surface of the lens and the lens barrel, the end of the dismantling head is a sharp wedge-shaped surface, and the dismantling head is a sharp wedge-shaped surface. The inside of the head is provided with a pressing block for pressing the lens, and the elastic element is driven between the pressing block and the dismantling head to perform vertical reciprocating extrusion of the lens. The inner bottom of the disassembling head is provided with a Cavity A, the inner top of the disassembly head is provided with a cavity B, and a vertically extending cylindrical opening is provided between the cavity A and the cavity B, and the cylindrical opening is coaxially fitted There is a guide rod for vertical sliding on the cylindrical opening, and the top of the guide rod is screwed with a guide block located in the cavity B. The dismantling structure of the bad lens is simple, which can solve the problem of difficult dismantling of the bad lens barrel and the problem of scrapping the lens of the bad lens barrel after dismantling. It can be knocked out easily.

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...
