Abstract
It is an object of the present invention to provide a method of moving a stage platform arranged in a vertical plane form using a resilient hinge mechanism and a driver of a translational-translational-rotation (PPR) structure, with a compensating counterbalance on the platform And a load acting on the elastic hinge can be reduced. The present invention provides an elastic hinge-based vertical plane fine driving stage for a heavy load.
Description
The present invention relates to an elastic hinge-based vertical plane fine driving stage for a heavy load, and more particularly, to a vertical plane fine driving stage for a heavy load, To a high-load, elastic-hinge-based vertical plane microdriving stage.
BACKGROUND ART [0002] In recent years, a stage device for moving an object three-dimensionally has been widely used in various fields. Especially in high-tech industrial fields such as a semiconductor field and a bio field, it is necessary to use a microdrive stage having high precision. It is a matter of course that such a fine driving stage requires precision, miniaturization, light weight, and the like.
As described above, in the fine driving stage in which precision is required, a driving device using a piezoelectric element is generally used as the driving device. A piezoelectric element is a device that has a piezoelectric effect that generates a voltage when a mechanical pressure is applied and a mechanical deformation when a voltage is applied thereto. The piezoelectric element has fast response and high resolution and is widely used as a precision driver.
On the other hand, the flexure hinge means that the elastic modulus in one direction is formed to be relatively larger than the elastic modulus in the other direction by using the structural shape, and as a result, the movement with the greater elastic modulus is limited, And a structure capable of moving only with a small coefficient. Such an elastic hinge-based mechanism is capable of moving to a high precision so as to have a resolution of nanometer scale, and is widely used as a component of a fine driving stage in addition to the above-described piezoelectric element.
Various techniques for a fine driving stage using a piezoelectric element and an elastic hinge mechanism are disclosed. Korean Patent Laid-Open Publication No. 2013-004613 ("Flexible Hinge-Based Piezoelectric Driving Stage of Multi-Layered Structure ", 2013.01.14, hereinafter referred to as Prior Art 1), Korean Patent Publication No. 2011-0087418 .03, hereinafter referred to as Prior Art 2), various configurations of a nano-scale precision stage using a piezoelectric element and an elastic hinge-based mechanism are shown. Such an elastic hinge-based mechanism has a great advantage in that it can guide very precise movement in a small area as well described in the prior art document 1 and the like. However, as mentioned in the preceding
Another problem of the elastic hinge-based mechanism is that, when a large load is applied, an excessive stress acts on the elastic hinge, resulting in damage or incorrect operation of the device. In particular, in the case of the vertical stage, since the stage load is concentrated on the elastic hinge portion by gravity, design deformation that increases the thickness of the hinge is inevitably required to prevent breakage. However, when the thickness of the hinge is increased, the magnitude of force to be applied for deformation of the hinge portion increases. That is, as the thickness of the hinge increases, the deformation becomes difficult and the small displacement is caused. As a result, There is a growing problem.
However, in the case of the conventional stage, there is a limitation in improving the accuracy due to the friction and clearance by the contact type guide. As described above, in the case of the stage including the elastic hinge-based mechanism, It is preferred because of its high accuracy. Accordingly, in the elastic hinge-based mechanism applied to the fine driving stage, as described above, there is a growing demand for a structure that can withstand higher loads than ever.
SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a stage platform arranged in a vertical plane, In which the load acting on the elastic hinge can be reduced by providing a counterbalance for compensating for the platform on the platform.
According to an aspect of the present invention, there is provided an elastic hinge-based vertical plane microdrive stage for heavy load including a translating-translating elastic hinge mechanism for connecting a fixed end and a movable end, and a driving unit for applying motion At least three drivers (100) formed to be movable in three directions; A

Also, the stage may be configured to be driven such that the moving range is in the range of several / 10 to several mm.
The stage may also be configured to be driven such that the load range is in the range of several to several hundred kilograms.
According to the present invention, in a fine moving stage moved by an elastic hinge-based actuator including an elastic hinge mechanism, a load acting on the elastic hinge is increased by providing a counterbalance for compensating the stage platform There is an effect that it can be reduced. More specifically, in the present invention, since the platform of the stage is balanced with the counterbalance load for compensation, the relative load of the platform is ideally zero, and in fact, do. That is, the magnitude of the load on the elastic hinge connecting the platform and the actuator is ideally zero, in fact very small.
According to the present invention, since a very small load is applied to the elastic hinge connecting the platform and the actuator, there is no problem even if the weight of the platform is much larger than the conventional one. In other words, the present invention solves the problem that the usable weight is limited due to the restriction due to the structural rigidity of the elastic hinge itself in the micro-driving stage, and it is a remarkable technique that can drive a high- It is effective. More specifically, according to the present invention, since the total load limit of the object and the platform is about ten kilograms due to the breakage problem of the elastic hinge, the fine hinge drive using the elastic hinge- There is a big effect.

Hereinafter, an elastic hinge-based vertical plane fine driving stage according to the present invention having the above-described structure will be described in detail with reference to the accompanying drawings.
First, the elastic hinge will be briefly described with reference to FIG. The elastic hinge is also referred to as a flexure. The elastic hinge is a flexible material having a shape such that the elastic modulus in one direction is relatively larger than the elastic modulus in the other direction in an object made of a material such as a metal material, . When an external force is applied to such a structure, little movement occurs on the side having a large elastic modulus, and only a movement toward a side having a small elastic modulus occurs. As a result, movement in any one direction You will be able to guide.
The simplest method of making the shape of the structure capable of performing such an elastic hinge is to make the thickness of one side of the structure thinner than the other directions. Of course, the force exerted on such an elastic hinge should be limited to such a range that the elastic deformation occurs at the portion where the thickness is thinly formed. If plastic deformation occurs due to too large a force applied to a thin-walled portion, the elastic hinge will be damaged, and it will not be able to play the role of limitation and guidance as described above.
An example of the simplest elastic hinge is shown in Fig. 1 (A). As shown in Fig. 1 (A), a body S extending long in the lateral direction (with reference to the drawing) has a portion S having a very thin thickness in the vertical direction at a position deviated to the left. In this case, the left end is a fixed end, and the right end is a moving end. Therefore, when a force is applied to the structure of FIG. 1 (A), deformation occurs only at the portion where the thickness is extremely thin, that is, the S portion. Therefore, as shown by a dotted line in FIG. 1 (A) Thereby rotating and moving. At this time, if the force applied to the body is within the elastic deformation range of the material of the body, the movable end is elastically deformed to rotate around the S portion, and when the applied force is lost, the movable end returns to the original position .
Figure 1 (B) shows a simple example of a 4-link mechanism for translational motion. The four-bar linkage is the most basic form of instrumentation in the field of kinematics. In the case of a three-bar link, the shape of a triangle that can be composed of three links is fixed as one triangle because it is a single one, whereas in the case of a four-bar link, , And if each link is connected to a rotating joint, it becomes a mechanism capable of implementing various movements. Also, the four-bar linkage is the simplest type of linkage mechanism that can be moved in this way, so it is easy to analyze the movement and is the most basic mechanism in the field of kinematics. In the four-bar linkage mechanism, it is possible to realize numerous movements depending on how to determine the four link lengths, the fixed link and the moving point, and of course, to realize a simple movement such as rotational movement or translational movement It is easy to do. Fig. 1 (B) shows a simple example of implementing up-and-down translational movement (with reference to Fig. 1 (B)) using such a four-bar linkage.
Fig. 1 (C) shows an example in which an elastic hinge is applied to a four-bar linkage implementing this translational motion. The left side view of FIG. 1 (C) shows a case where the rotating joint part of the four-bar link mechanism as shown in FIG. 1 (B) is formed as shown in part S of FIG. 1 (A) It is the same mechanism as the mechanism of (B). The right side view of Fig. 1 (C) shows two links connecting the fixed end link and the movable end link (up and down moving link) of Fig. 1 (B) and the rotating joints located at both ends of the link And is replaced with elongated elastic hinges in the form of a thin plate. As a result, it is possible to realize the same upward and downward translational motion as the mechanisms shown in the left drawing of Figs. 1 (B) and 1 (C).
1 (D) is a top view of C-flex, which is a rotary elastic hinge product currently commercialized and widely used. The C-flex is formed in a cylindrical pipe shape extending vertically in its entirety, and is formed in a shape in which the middle of the pipe is cut off, and includes a thin plate crossing the upper body and a thin plate crossing the lower body with respect to the cut- (And therefore, the thin plate as seen in FIG. 1 (D) appears to be arranged in a cross shape on the upper surface). One of the upper body and the lower body is a fixed end and the other is a moving end. When a force is applied to the rotary elastic hinge, the movable end moves only in the direction of rotating about the axis of the cylindrical pipe. That is, by using the elastic hinge of the type shown in Fig. 1 (D), the movement of the movable end can be restricted only in the rotating direction.
Hereinafter, a structural example of the elastic hinge mechanism used in the stage of the present invention and an embodiment of the actuator will be described with reference to FIGS. 2 and 3. FIG. First, a stage to be driven in the present invention is formed in a planar shape in which a stage platform on which an object is placed stands in a vertical plane, that is, a plane perpendicular to the ground plane. In the vertical plane in which the platform is included, The axis translation direction, and the? Axis rotation direction.
Figure 2 shows an example of a translational-translational-rotation (PPR) elastic hinge mechanism. The elastic hinge mechanism shown in Fig. 2 includes a first part, which is spaced apart from the fixed end in the x-axis direction, a second part that is spaced apart from the first part in the y- A second part, and a third part, which rotates with respect to the second part, are sequentially connected to each other, the end of the first part forms a fixed end, the end of the third part moves Thereby forming an end. More specifically, it is as follows.
The first part is spaced apart in the x-axis direction with respect to the fixed end, and the fixed end and the first part are connected by a long elastic hinge pair that implements translational motion as shown in the right-hand side of Fig. 1 (C). Thus, the first part is translationally limited and guided only in the y-axis direction with respect to the fixed end.
The second part is spaced apart in the y-axis direction with respect to the first part, and the first part and the second part are also connected by a long elastic hinge pair that implements translational motion as shown in the right-hand side of Fig. 1 (C) . Thus, the second part is translated and guided only in the x-axis direction with respect to the first part.
The third part extends in the x-axis direction, the left end forms a fixed end (relative to the second part), and the right end forms a moving end. Also, the left end of the third part is connected to the second part, and is connected by a rotational elastic hinge as shown in FIG. 1 (B). Therefore, the right end (moving end) of the third part is limited and guided only in the? -Axis direction around the left end (fixed end) connected to the second part.
As the first to third parts are connected to each other by the PPR elastic hinge, the moving end of the elastic hinge mechanism composed of the first to third parts is moved in the x-axis direction translation, the y- Direction rotational motion can be realized. In this case, since the x-axis direction, the y-axis direction, and the? -Axis direction are not absolute directions, in order to more generalize the above-described translational-translational-rotational motion, a first direction translational motion (a direction perpendicular to the first direction) (In the axial direction perpendicular to the plane formed by the first direction and the second direction) center-to-center rotational motion in the second direction.

In order to solve this problem, the present invention proposes a structure in which a load imbalance is provided by providing an equilibrium load on the stage platform, thereby substantially reducing the stress applied to the elastic hinge of the actuator. That is, by using an inverse balancing load having the same total load as the platform, the influence of the gravity actually acting on the platform, that is, the load is ideally zero, in fact very small. When the actuators including the elastic hinge mechanism are connected to the platform provided with the counter balance load as described above (in the past, stress corresponding to the platform load has been applied to the elastic hinge portion), according to the present invention, Ideally zero, in fact only a very small magnitude of the load.
