This gear ring 122 is installed on this plummer 121, and this gear ring 122 is provided with interior teeth 1221, and the type and the parameter of teeth 1221 can be set according to actual needs in this.
This central gear 123 is arranged on this plummer 121 and with this gear ring 122 and is total to central axis O
1, this central gear 123 is provided with outer teeth 1231.
This drive source 124 makes it around central axis O in order to drive this central gear 123
1Rotation.In the present embodiment, this drive source 124 comprises a driver 1241 and a transmission shaft 1242, this driver 1241 is motors, it is arranged on a side that deviates from this light source 11 of this plummer 121, the center of this central gear 123 of one end of this transmission shaft 1242 is fixedly connected, and its other end passes this plummer 121 and these driver 1241 mechanical couplings.This driver 1241 drives these transmission shaft 1242 rotations to drive this central gear 123 around central axis O
1Rotation, the rotational speed of this central gear 123 also can be controlled by this driver 1241 simultaneously.
These four swing pinions, 125 rotating being arranged on this plummer 121 for example are provided with ball, rotating shaft etc. between this swing pinion 125 and this plummer 121.In the present embodiment, these four swing pinions 125 evenly are arranged between this gear ring 122 and this central gear 123 along the circumferencial direction of this central gear 123, each swing pinion 125 is provided with outer teeth 1251, and the outer teeth 1251 of each swing pinion 125 are meshed with the interior teeth 1221 of this gear ring 122 and the outer teeth 1231 of this central gear 123 respectively; Being provided with two with these light source 11 facing surfaces 1252 and being used for the ccontaining storage tank 1253 that is exposed thing of each swing pinion 125, these two storage tanks 1253 are with the central axis O of this swing pinion 125
2Be the rotational symmetry setting.
Be understandable that the position of center line with these plummer 121 opposed bottom surface of each swing pinion 125 can be provided with a rotating shaft 1254, this plummer 121 is provided with one with central axis O simultaneously
1 Annular groove 1211 for the center, at this, the rotating shaft 1254 of four swing pinions 125 all is installed in this annular groove 1211, when being rotated, each swing pinion 125 has a fixation locus on this plummer 121, the resistance that each swing pinion 125 is rotated on this plummer 121 is littler, as shown in Figure 2.The quantity of this swing pinion 125 is not limited to present embodiment, and this swing pinion 125 can be one or more (for example four), as long as it can be meshed with this gear ring 122 and this central gear 123 respectively.The quantity and the distribution mode that are arranged on the storage tank 1253 on the surface 1252 of this swing pinion 125 are not limited to present embodiment, this storage tank 1253 can be one or more (for example four), and it can also can irregularly distribute on the surface 1252 of this swing pinion 125 in even distribution.
Below will expose with the element that scribbles UV glue in the lens barrel to the camera lens module is example, and the course of work of a kind of exposure device 10 that first embodiment of the invention is provided is briefly described:
Lens barrel is placed on respectively in the storage tank 1253 of each swing pinion 125, makes the element that scribbles UV glue in this lens barrel relative with this light source 11;
Because this light source 11 penetrates to such an extent that the intensity distributions of light beam is normally uneven, the light intensity of the point different with the relative distance of this light source 11 is not simultaneously in this light source 11 is mapped to this gear ring 122, generally be that the relative distance of point in this gear ring 122 and this light source 11 is more little and light intensity is strong more, above-mentioned each swing pinion 125 can be around this central axis O
2Along the direction rotation opposite with this direction A, so the point on the surface 1252 of each swing pinion 125 and the relative distance of this light source 11 will produce cyclical variation, promptly naming a person for a particular job on the surface 1252 of each swing pinion 125 periodically passed through stronger zone and the more weak zone of light intensity of light intensity.Further, point in this light source 11 is mapped to this gear ring 122 is not along the light intensity of the circumferencial direction of this central gear 123 not simultaneously yet, generally be the circumferencial direction periodic distribution of the light intensity of the light beam that penetrates of this light source 11, and this each swing pinion 125 is around above-mentioned central axis O along this central gear 123
1A rotation in the direction makes the stronger zone and the more weak zone of light intensity of process light intensity of property dot cycle on the surface 1252 of this each swing pinion 125.This drive source 124 can also be controlled the rotational speed of this central gear 123 in addition, so the storage tank 1253 of each swing pinion 125 also will produce cyclical variation in light intensity stronger zone and the more weak time that the zone stopped of light intensity.
When the relative distance of this storage tank 1253 and this light source 11 diminishes gradually, the light intensity that is mapped to the light beam in the lens barrel that is placed in the storage tank 1253 is more and more stronger, when the relative distance of this storage tank 1253 and this light source 11 becomes big gradually, the light intensity that is mapped to the light beam in the lens barrel that is placed in this storage tank 1253 more and more a little less than, when this storage tank 1253 around above-mentioned central axis O
1During along the rotation of the circumferencial direction of this central gear 123, the light intensity that is mapped to the light beam in the lens barrel that is placed in the storage tank 1253 will produce cyclical variation, control simultaneously be placed on lens barrel in the storage tank 1253 in light intensity the strong and more weak time that the zone stopped of light intensity, then can make the UV glue uniform exposure in the lens barrel, thereby the UV glue in the assurance lens barrel can be not over-exposed or under-exposed, thereby make UV glue cling the interior optical element of lens barrel preferably.
See also Fig. 3 and Fig. 4, a kind of exposure device 20 that second embodiment of the invention provides, the exposure device 10 that itself and above-mentioned first embodiment provide is basic identical, and difference is:
This exposure device 20 comprises one in order to drive gear ring 222 around central axis O
1The drive source 224 of rotation, in the present embodiment, this drive source 224 comprises 2241 and driven wheels 2242 of a driver (for example motor);
These gear ring 222 rotating being arranged on the plummer 221, in the present embodiment, this gear ring 222 be provided with rotating shaft 2223 with these plummer 221 opposed bottom surface, this plummer 221 is provided with central axis O simultaneously
1For the annular groove 2211 at center, at this, the rotating shaft 2223 of this gear ring 222 is installed in this annular groove 2211; This gear ring 222 is provided with outer teeth 2222, and the outer teeth 2222 of this gear ring 222 are meshed with the driven wheel 2242 of this drive source 224;
In the present embodiment, this drive source 224 can drive this gear ring 222 around central axis O
1Along direction B rotation, and then drive each swing pinion 125 around central axis O
1B rotation in the direction, each swing pinion 125 is around the central axis O of himself simultaneously
2B rotation in the direction, so naming a person for a particular job on the surface 1252 of each swing pinion 125 is periodic through stronger zone and the more weak zone of light intensity of light intensity, this drive source 224 can also be controlled the rotational speed of this gear ring 222 in addition, so the storage tank 1253 of each swing pinion 125 also will produce cyclical variation in light intensity stronger zone and the more weak time that the zone stopped of light intensity.This shows, utilize this exposure device 20 to make and be exposed the thing uniform exposure.
In addition, for the person of ordinary skill of the art, can make other various corresponding variations, and all these change the protection domain that all should belong to claim of the present invention according to technical scheme of the present invention and technical conceive.
