Description
Technical field
The present invention relates to a kind ofly can move and, be specially a kind of fully automatic non lead-tin printing machine precisely locating platform in X-axis, Y direction based on compliant mechanism around the three-freedom degree precision locating platform that the Z axle rotates.
Background technology
At present, the fully automatic non lead-tin printing machine is the key equipment on the SMT industry production streamline, and in the full-automatic stencil printing machine, the precisely locating platform under the vision guide is its core component, and the positioning accuracy of precisely locating platform directly determines the quality of paste solder printing.And along with the miniaturization day by day of paster components and parts, the pin-pitch of surface mount elements is more and more littler, and fully automatic non lead-tin printing machine cycle of updating is also shorter and shorter, presses for the printing precision that fundamentally improves printing machine.Traditional full-automatic stencil printing machine great majority all do not have automatic pretension function, and some printing machines have been installed easy common spring, have certain pretension function, but effect are unsatisfactory.
Summary of the invention
The objective of the invention is to provides a kind of full-automatic stencil printing machine locating platform based on compliant mechanism at the existing above-mentioned shortcoming of prior art.The present invention combines rigid mechanism and large deformation compliant mechanism, forms a kind of compliant mechanism of broad sense.This platform has automatic guide, automatic pretension function, can effectively solve the technical barrier of present existence, has fabulous practical value.
For achieving the above object, the present invention has taked following technical proposals:
A kind of full-automatic stencil printing machine locating platform based on compliant mechanism, it is made up of motion platform 1, pedestal 26, three groups of identical drive units, two groups of identical pre-tightening apparatus.In three groups of drive units, first group of drive unit is made up of drive source 6, pin 7, slide block 8 and guide rail 9 respectively; Second group of drive unit is made up of drive source 10, pin 11, slide block 12 and guide rail 13 respectively; The 3rd group of drive unit is made up of drive source 14, pin 15, slide block 16 and guide rail 17 respectively; The bottom of these three groups of drive units is fixed on the support 26.In two groups of pre-tightening apparatus, wherein form by compliant mechanism 18, compliant mechanism 19, slide block 20 and guide rail 21 for one group; Another group is made up of compliant mechanism 22, compliant mechanism 23, slide block 24 and guide rail 25.Motion platform 1 is installed on the pedestal 26 by ball 2, ball 3, ball 4, ball 5.When drive source 6, drive source 10, drive source 14 have the displacement input, transmit motion to motion platform 1 by the pin in the drive unit, slide block and guide rail, motion platform 1 will move to an accurate position, and the exact position of satisfying paste solder printing is to alignment request.
Ball 2, ball 3, ball 4, ball 5 are distributed in four jiaos of motion platform 1, play the effect of supporting movement platform 1, and frictional force is very little during simultaneously owing to the ball motion, can effectively prolong the useful life of alignment stage.In two groups of pre-tightening apparatus, slide block and guide rail are all arranged, can effectively improve the positioning accuracy of motion platform 1, simultaneously because the strain of compliant mechanism, it can be born axially and radial load, and axially and radially have bigger deformation characteristic, can carry out effective pretension three groups of drive units, reduce screw thread error of backlash in the drive unit, thereby improved the repetitive positioning accuracy of locating platform.
The input of whole platform is made up of drive source 6, drive source 10 and drive source 14, coordinates the input displacement of three drive sources, can make motion platform 1 reach contraposition position accurately.
Compare with existing platform, the present invention has following effect:
1. the present invention adopts rigid mechanism and large deformation compliant mechanism is combined, and the positioning accuracy of platform is largely increased, and is that traditional rigid mechanism is unapproachable
2. locating platform of the present invention has two groups of pre-tightening apparatus and three groups of drive units, makes four limits of motion platform 1 that guide rail and slide block all be arranged, and can accurately lead, and improves the positioning accuracy of platform.Traditional motion platform has only both sides that guide rail and slide block are arranged, discontinuity equalization, and it is not accurate to lead yet, and serious wear is difficult to guarantee permanently effective accurate location.
3. two groups of pre-tightening mechanisms can carry out effective pretension to three groups of drive units among the present invention, reduce the error of backlash of screw thread in the drive unit, thereby have improved the repetitive positioning accuracy of locating platform.Adopting all-in-one-piece compliant mechanism, also is that the positioning accuracy of platform is effectively guaranteed.

Embodiment
Below in conjunction with Figure of description 1, Fig. 2 the specific embodiment of the present invention is described further:
As shown in Figure 1, the fully automatic non lead-tin printing machine precisely locating platform based on compliant mechanism of the present invention is made up of motion platform 1, pedestal 26, three groups of identical drive units, two groups of identical pre-tightening apparatus.In three groups of drive units, first group of drive unit is made up of drive source 6, pin 7, slide block 8 and guide rail 9 respectively; Second group of drive unit is made up of drive source 10, pin 11, slide block 12 and guide rail 13 respectively; The 3rd group of drive unit is made up of drive source 14, pin 15, slide block 16 and guide rail 17 respectively; The bottom of these three groups of drive units is fixed on the support 26.In two groups of pre-tightening apparatus, wherein form by compliant mechanism 18, compliant mechanism 19, slide block 20 and guide rail 21 for one group; Another group is made up of compliant mechanism 22, compliant mechanism 23, slide block 24 and guide rail 25.Motion platform 1 is installed on the pedestal 26 by ball 2, ball 3, ball 4, ball 5.
In first group of drive unit, drive source 6 provides the input displacement, this input displacement acts on the slide block 8 by pin 7, slide block 8 guide rail 9 relatively slides, guide rail 9 is installed on the motion platform 1, like this, drive source 6 provides the input displacement to be delivered to motion platform 1 by pin 7, slide block 8, guide rail 9.The drive principle of other two groups of drive units and first group are identical, change the input displacement of three drive sources, can make motion platform 1 reach different positions, thereby make motion platform have three freedoms of motion moving and that rotate around the Z axle along X-axis, y-axis shift.
In two groups of pre-tightening apparatus, a wherein end of compliant mechanism 18, compliant mechanism 19, compliant mechanism 22, compliant mechanism 23 is fixed on the pedestal, the other end is separately fixed on slide block 20, the slide block 24, and slide block 20 is installed on the guide rail 21, and guide rail 21 is installed on the motion platform 1; Same piece 24 is installed on the guide rail 25, and guide rail 25 is installed on the motion platform 1.The input of three groups of drive units is with 1 motion of actuation movement platform, and during motion platform 1 motion, compliant mechanism in two groups of pre-tightening apparatus is squeezed power and produces distortion, the deformation force that this distortion produces reacts on motion platform 1, thereby motion platform 1 is abutted against on three groups of drive units, thereby reduced the screw thread error of backlash in the drive unit, improved repetitive positioning accuracy.
All there are guide rail and slide block in four limits of motion platform 1, make motion platform stress equalization, guiding accurately, improve the positioning accuracy of platform.Compliant mechanism in the pre-tightening apparatus can replace with common spring, explains with compliant mechanism in the present embodiment.
Ball 2, ball 3, ball 4, ball 5 are installed on the motion platform 1, are distributed in four jiaos of motion platform 1, play the effect of supporting movement platform 1.
