The present invention is lens combination assembling device and method for assembling lens combination into lens barrel of camera. The lens combination assembling device includes one lens barrel and one heating element. The lens combination assembling method includes the following steps: providing the said lens combination assembling device, heating the lens barrel homogeneously with the heating element to increase the inner diameter of the lens barrel, assembling the lens combination inside the lens barrel lightly and clamping the lenses after cooling the lens barrel.
Description
[technical field]
The invention relates to a kind of camera lens assembling device and assemble method.
[background technology]
For guaranteeing image quality, the performance of optical lens and imaging resolution require all higher, therefore must guarantee the eccentric less of lens barrel and eyeglass.At present, common practices is that a series of structures are set in lens barrel, by external force eyeglass is pressed into lens barrel by force, and by the quite skilled skilled worker's assembling of technology.
The lens barrel of one existing fixing eyeglass, as announce in No. the 5th, 493,452, the United States Patent (USP) on February 20th, 1996 disclose, see also Fig. 1 and Fig. 2, this lens barrel comprises cylindrical drum 2, three equally distributed juts 3, a ring-type adjacency section 4 and three equally distributed fulcrums 5.Adjacency section 4 is positioned at the inwall of cylindrical drum 2; Jut 3 is a bit of annulus, and 4 extend to cylindrical drum 2 ends always from the adjacency section; Fulcrum 5 is bigger slightly than adjacency section 4 width, and each fulcrum 5 terminal definite one and the perpendicular plane of eyeglass 1 optical centre axle by this mechanism, do not have off-centre and inclination between eyeglass 1 and lens barrel; During assembly lens 1, eyeglass 1 is suppressed into cylindrical drum 2 up to against fulcrum 5 along jut 3.This lens barrel structure is comparatively complicated, and eyeglass and lens barrel manufacturing accuracy require very high, and lens barrel and eyeglass easy deformation when suppressing eyeglass into lens barrel, and lens barrel and eyeglass are caused damage, causes assembling back yields lower.
In view of above shortcoming, be necessary to provide a kind of simple in structure, difficulty of processing is lower, makes lens barrel structure simple, is convenient to assembly lens, and can damage not arranged to lens barrel and eyeglass, makes higher lens assembling device and the assemble method of eyeglass assembling yields.
[summary of the invention]
The object of the present invention is to provide a kind of lens assembling device, this apparatus structure is simple, difficulty of processing is lower.
Another object of the present invention is to provide a kind of lens assembling method, it damages less in the time of can making lens barrel and eyeglass assembling, and eyeglass is with respect to the lens barrel accurate positioning.
Lens assembling device of the present invention is used for the eyeglass camera lens barrel of packing into, and it comprises a lens barrel and heating element, and this heating element can evenly heat lens barrel.
This lens assembling method is used for eyeglass is fit in the lens barrel, and a lens barrel, heating element and eyeglass at first are provided.This heating element can evenly heat lens barrel, and during the heating element heating, heat evenly is passed to lens barrel, thereby lens barrel is heated up, and the lens barrel internal diameter increases, and at this moment can like a cork lens set be filled in the lens barrel, heating element cooling then, the lens barrel temperature also reduces, and thus eyeglass is tightened.
Compare prior art, lens assembling device of the present invention is simple in structure, difficulty of processing is lower, and it is simple to have simplified lens barrel structure; Lens assembling method of the present invention is simple to operate, and the lens barrel of like a cork eyeglass being packed into makes the when assembling damage of lens barrel and eyeglass less, and eyeglass makes eyeglass assembling yields higher with respect to the lens barrel accurate positioning.

[embodiment]
Lens assembling device of the present invention and method are applicable to camera assembling, are used for eyeglass is packed in the lens barrel 10.
See also Fig. 3 and Fig. 4, this lens assembling device comprises a lens barrel 10, a well heater 20 or 20 ' and temperature controller 30.Temperature controller 30 comprises power supply (figure does not show) and temperature control unit (figure does not show).
The first embodiment of the invention lens assembling device, see also Fig. 3, lens barrel 10 is a cylindrical shape, on its external cylindrical surface external thread is arranged, well heater 20 is a cylindrical shape, on its inner cylinder face internal thread is arranged, lens barrel 10 places in the well heater 20, the screw-internal thread fit of the external thread of lens barrel 10 and well heater 20 so that lens barrel 10 can be heated evenly, thereby can evenly enlarge its internal diameter after heating, so that can accurately locate when eyeglass is installed, the material of this well heater 20 can be metal, and the power positive cathode of temperature controller 30 is connected on the well heater 20, so that its power supply back homogeneous radiation heat energy.
The second embodiment of the invention lens assembling device, see also Fig. 4, lens barrel 10 is a cylindrical shape, on its external cylindrical surface external thread is arranged, well heater 20 ' and be right cylinder, its size just can cooperate with footpath within the lens barrel 10, so that lens barrel 10 can thermally equivalents, this well heater 20 ' place in the lens barrel 10, the inner cylinder face of lens barrel 10 and well heater 20 ' external cylindrical surface cooperate, well heater 20 ' material can be metal, the power positive cathode of temperature controller 30 be connected to well heater 20 ' on.
Need eyeglass (figure does not show) when being assembled in lens barrel 10, by 30 pairs of well heaters 20 of temperature controller or 20 ' energising, well heater 20 or 20 ' temperature raise earlier, and heat evenly is passed on the lens barrel 10, lens barrel 10 temperature are raise, so this lens barrel 10 increases its internal diameter owing to being heated evenly to expand, and behind the heating certain hour, stops heating, and pack in the lens barrel 10 eyeglass of appropriate size and preferable location, the temperature of this lens barrel 10 reduces gradually, and its internal diameter reduces, thereby eyeglass is tightened.
Be appreciated that between the lens barrel 20 of lens assembling device first embodiment of the present invention and the well heater 30 to be not limited to threaded engagement,, the central shaft of lens barrel 20 overlapped with the central shaft of well heater 30 as lens barrel 20 directly being inserted in the well heater 30; The well heater 20 of second embodiment ' be not limited to right cylinder, it also can be cylindrical shape, only needs identical the getting final product of internal diameter of its external diameter and lens barrel 10; Similarly, this well heater 20,20 ' be not limited to cylindric or right cylinder, only need it to generate heat and with heat transferred to lens barrel 10, and lens barrel 10 each several part temperature even variation are got final product, such as, resistance wire is wound on the lens barrel 10, also can be some well heaters 20,20 ' be uniformly distributed on the lens barrel 10.
