Abstract

A disassembling device for lens module which has a lens barrel and at least one optical component received in the lens barrel. The disassembling device includes a carrying platform, a cylindrical cutting tool, a cutting tool holder, and a driving device. The carrying platform includes a carrying surface for placement of the lens module. The cutting tool is arranged onto the cutting tool holder and is collinear with the lens barrel. A diameter of the cutting tool is greater than an inner diameter of the lens barrel and is less than an external diameter of the lens barrel. The driving device is connected to the cutting tool holder and moves the cutting tool holder along a central axis of the lens barrel, thereby the lens barrel can be cut and thinned by the cutting tool.

First claim

What is claimed is:

1. A disassembling device for a lens module, the lens module comprising a lens barrel and at least one optical component; the disassembling device comprising:
a carrying platform comprising a carrying surface, the carrying surface configured for carrying the lens module;
a base;
a cutting tool;
a cutting tool holder; and
a driving device;
wherein the cutting tool is arranged on the cutting tool holder and is collinear with the lens barrel, a diameter of the cutting tool is greater than an inner diameter of the lens barrel and is less than an external diameter of the lens barrel; the driving device is connected to the cutting tool holder and drives the cutting tool holder along a direction perpendicular to a center axis of the lens barrel, causing the cutting tool to cut the lens barrel.

2. The disassembling device as claimed in claim 1 , wherein the disassembling device further comprises a base, the base comprising a top plate and two side plates vertically connected to both ends of the top plate; the top plate comprises an upper surface and an opposite lower surface; the top plate comprises a guide hole passing through the upper surface and the lower surface; the cutting tool holder received in the guide hole and moves around an axial direction of the guide hole; the two side plates arranged onto the carrying surface, the lower surface faces the carrying surface with a space between.

3. The disassembling device as claimed in claim 2 , wherein the carrying surface comprises an accommodating hole for holding the lens module, and the guide hole and the accommodating hole is collinear.

4. The disassembling device as claimed in claim 3 , wherein the accommodating hole passes through the bottom surface; the disassembling device further comprises a convex plate, the convex plate received in the accommodating hole.

5. The disassembling device as claimed in claim 4 , wherein the accommodating hole comprises a first accommodating portion close to the carrying surface and a second accommodating portion is collinear with the first accommodating portion; a diameter of the second accommodating portion is greater than a diameter of the first accommodating portion; the convex plate comprises a top portion faces the first accommodating portion and a bottom portion faces the second accommodating portion; the top portion is slightly lower than the carrying surface.

6. The disassembling device as claimed in claim 2 , wherein the driving device comprises a cam, a drive shaft, a handle, and a supporting plate; the cam comprises a first side and a second side; the first side comprises an elliptical track groove; one end of the drive shaft is fixedly connected with the cutting tool holder, another end of the drive shaft received in the track groove and moves around the track groove; the handle is formed extending from the second side; the supporting plate is arranged onto the upper surface and comprises a through hole; the handle is rotatably received in the through hole.

7. The disassembling device as claimed in claim 6 , wherein the cutting tool holder comprises a first connector and a second connector, both the first connector and the second connector are substantially cylindrical; the first connector and the second connector are connected by a plug; the first connector is received in the guide hole, the second connector connected to the drive shaft.

8. The disassembling device as claimed in claim 7 , wherein one end of the cutting tool has an external thread; one end of the first connector away from the second connector comprises a screw hole; the cutting tool is arranged onto the first connector by matching the external thread and the screw hole.
