Background technology
The development of optical information technology is promoting the progress of telecommunications, along with the development of optical fiber communication and optical fiber sensing technology, optoelectronic device be prepared into the key that further develops for the optical information technology.The encapsulation technology of integrated opto-electronics device influences the reliability of this optoelectronic device, and crucial packaging technology can significantly be enhanced productivity with full-automatic sealed in unit, guarantees device quality.
The fiber alignment platform is the core cell of optical fibre device encapsulation manufacturing system, and the performance of platform has determined the alignment precision that can realize.The precision of platform, speed, reliability are the principal elements that will consider.Platform feature should satisfy following requirement: the large area scanning that initial light coupling search can be provided; Realize the nanometer positioning of fine registration: the enough strokes that make things convenient for the device loading and unloading.Simultaneously, docking platform must provide fiber alignment multivariant adjustment, and takes into account cost and versatility.
The optical fiber align platform adopts the guide tracked and Piezoelectric Ceramic formula of thick stick more at present, and the former exists cost height, bulky shortcoming, and the latter's range of movement is very limited, and cost is higher, controls also more complicated.And because ubiquitous backlass between stepper motor and the screw mandrel causes the instability of this type of platform in backhaul control.
The utility model content
1, technical matters to be solved:
Existing optical fiber align platform cost height, volume is big, and range of movement is very limited, and ubiquity direction gap between stepper motor and the screw mandrel, and backhaul control is gone up unstable.
2, technical scheme:
In order to overcome the above problems, the utility model provides a kind of optical fiber align micromotion platform, comprise flexible hinge elasticity platform 3, micromotion platform 4 and X-axis stepper motor 8 and y-axis stepper motor 8 ', elasticity platform 3 is installed on the base plate 5, micromotion platform 4 is positioned at flexible hinge elasticity platform 3, each stepper motor links to each other with a screw mandrel 9, each screw mandrel 9 top is connected push rod 10 with a push rod 10 internal thread, deep groove ball bearing 6 is housed, micromotion platform 4 contacts side surfaces of described deep groove ball bearing 6 and flexible hinge elasticity platform 3 inside on the push rod 10.The motion that push rod 10 is respectively micromotion platform 4Y axle, X axis provides required thrust ', when thrust disappearance micromotion platform 4 is got back to zero-bit automatically.Advancing of push rod 10 is subjected to 4 flexible hinges in the axial extruding of x/y all the time with resetting, and makes that nut, the screw mandrels in the push rod 10 do not have the gap at two operative orientations.Have groove 17 on the base plate 5, swing arm 13 and half-and-half bearing 14 are installed in the described groove 17, swing arm 13 and half-and-half bearing 14 form circumference and cooperate, and swing arm 13 can be swung back and forth in groove.Swing arm 13 contacts with the deep groove ball bearing 6 of push rod 10 lower ends, thereby it is reciprocating to promote push rod 10.
3 two adjacent side of flexible hinge elasticity platform are equipped with bracing frame web joint 12, and stepping Connection Block 7 is used for installing stepper motor on the bracing frame web joint 12 of every side.
On the flexible hinge elasticity platform 3 upper cover plate 2 is installed, on the described upper cover plate 2 pressing plate 1 is installed.
3, beneficial effect:
The optical fiber align micro flexible platform that the utility model provides, cost is low, and volume is little, and backhaul control is stable.

Embodiment
The present invention is described in detail below in conjunction with accompanying drawing.
Shown in Fig. 1-4, the optical fiber align micromotion platform has the both direction top offset, is respectively X-axis and Y-axis, and X-axis stepper motor 8 is arranged on the X-axis, and y-axis stepper motor 8 ' is arranged on the Y-axis.
When micromotion platform 4 needed the smart displacement of X-direction, X-axis stepper motor 8 started and promotes push rods 10, and makes the smart displacement of micromotion platform 4X direction of principal axis, but when needing the smart displacement of Y direction, principle is the same.
Flexible hinge elasticity platform is divided into four spaces, and the centre is micromotion platform.In each space inwall be provided with the compression spring 19 contact with micromotion platform 4.Because the existence of compression spring 19, under the effect of compression spring 19, the output of the big displacement quantity of stepper motor converts micrometric displacement to, improves the Motion Resolution rate.Simultaneously because the rebound effect of compression spring 19, make the reverse no gap of stepper motor screw mandrel.
When micromotion platform 4 needed the coarse positioning of X-direction to move, pneumatic line motor 11 drove swing arm 13 and swings back and forth, and swinging back and forth of swing arm 13 is converted into the linear reciprocating motion of push rod 10, moves at the coarse positioning of X-direction thereby promote micromotion platform 4.Boss structure 18 is arranged in the swing arm 13, back-moving spring 15 is housed on the boss structure 18, assurance swing arm 13 remains with pneumatic line motor 11 and contacts.Push rod 10 is two relatively independent unit with screw mandrel 9, push rod 10 just contacts with screw mandrel 9 with the extreme position of stepper motor reverse movement direction on the X/Y axle and does not have pressure, screw mandrel 9 drives via stepper motor can promote push rod 10 motions, thereby promotion micromotion platform 4 carries out displacement, swing arm 13 drives push rod 10 can only promote micromotion platform 4 displacements, and can not oppositely promote screw mandrel 9, thereby the elimination coarse positioning moves the influence to smart displacement.
The utility model is with the synthetic flexible hinge elasticity platform of two sliding platforms of X/Y axle, and the gap that screw mandrel advances, resets has also been eliminated in design.Make optical fiber align micromotion platform of the present utility model, cost reduces, and volume reduces simultaneously, has improved efficient.
