Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0015] Such as figure 1 As shown, the positioning device 10 provided by the first embodiment of the present invention includes a moving part 11 and a fixing part 12 .

[0016] The moving part 11 is a cylindrical structure, one end of which forms a first conical part 110 along the axis, and the first conical part 110 is a right cone.

[0017] The fixed part 12 is a cylindrical structure, and one end of the fixed part 11 relative to the moving part 11 forms a second conical part 120 with the same shape as the first conical part 110 along the axis, and the second conical part 120 is also a right cone.

[0018] Such as figure 2 As shown, the positioning device 20 provided by the second embodiment of the present invention includes a moving part 21 and a fixed part 22 .

[0019] The moving part 21 is a cylindrical structure, one end of which forms a first conic...

Abstract

The invention provides a polarizing device, which is used for detecting the machine station of the assembled drawtube. The machine station is provided with a bearing fixture containing the drawtube. The polarizing device comprises a fixed part and a moving part. The fixed part can be placed in the bearing fixture. One end of the fixed part far from the bearing fixture is mounted with the first polarizing part. One end of the moving part facing to the fixed part is mounted with the second polarizing part matched with the first polarizing part. The polarizing device can conveniently and easily check if the detecting machine station is polarized.

Description

technical field [0001] The invention relates to a device for detecting the assembly machine of a lens barrel, in particular to a positioning device for detecting the positioning of the machine. Background technique [0002] With the development of camera technology, lens modules are widely used in camera devices for various purposes, and the combination of lens modules with various portable electronic devices such as mobile phones, cameras, computers, etc., is favored by many consumers. [0003] Lens modules are generally composed of lenses, filters, spacers, etc. assembled into the lens barrel and then screwed into the lens holder. [0004] When assembling, the lens barrel is placed in the carrying fixture of the machine, and the lens, filter, etc. are picked up by the suction nozzle, clip or manipulator and other pick-up devices and put into the lens barrel. During the assembly process, the centers of optical components such as lenses and filters are not on the same strai...
