Description

Auto-adjusting balance stage {AUTO-ADJUSTING BALANCE STAGE}

The present invention relates to a balance stage used to set the declination angle of an object by automatically adjusting the tilt or balance of the object.

A balance stage is used in various industrial fields as a means for controlling the posture of an object or adjusting the balance. For example, in a semiconductor manufacturing process, a balance stage for tilting the substrate about each axis according to the work process may be used. In addition to the semiconductor industry, various types of balance stages have been developed and used in manufacturing and testing fields handling various precision parts.

For reference, such a balance stage may also be referred to as a balance stage, a tilting stage, or the like. For convenience, in this specification, these are collectively referred to as a balance stage.

As one of the conventionally known balance stages, the "precision driving tilt stage" of Korean Patent Laid-Open No. 10-2020-0113866 has a configuration that can reduce backlash while being simple in operation by using a swing operation of the upper stage. As another example, the "tilting stage system" of Korean Patent Laid-Open No. 10-2018-0023739 has proposed a configuration capable of adjusting the degree of balance of the stage with a simple structure by applying an operating force to the eccentric region of the stage. As another example, the "tilt stage device" of Patent Registration No. 10-1732851 has proposed a configuration in which the rotational motion of the rotating part and the vertical motion of the moving part are combined so that the multi-axis rotation of the stage can be simultaneously performed.

A more general form of the balance stage is a method in which a plurality of actuators are added to the stage and the stage is tilted according to the operation of each actuator. However, this method is expensive because a plurality of actuators are required, and precise control of each actuator is also not easy. In particular, when handling a heavy object, a larger number of actuators are required in proportion to the weight, and more precise control is required for even distribution of the weight.

Against this background, various types of modified balance stages as mentioned above have been proposed, but they also have a fairly complex structure and a large number of precision parts, so they are not easy to manufacture, and there are difficulties in actual handling or operation. In addition, most of the simplified form of the balance stage has a limit in precise angle control, so the range of use may be limited. Therefore, although various types of balance stages have been developed and used up to now, the demand for more improved types of balance stages continues.

Therefore, if the operating unit 180 is integrally formed with the central base 130 and moved together with the central base 130 , the operating unit 180 determines where the first rail 120 and the second rail 140 are located. Even if it is rotated to, it is possible to continuously maintain a state in meshing with the outer periphery of the first and second rails (120, 140).

The lower rail groove 121a may be disposed adjacent to the lower end of the first rail 120 to extend along the radially inner surface of the first rail 120 . A lower rail 112 may be mounted in the lower rail groove 121a. In addition, gear teeth may be formed on the radially outer surface of the first rail 120 .

According to the above, the first rail 120 may be supported by the lower rail 112 . If necessary, a bearing (not shown) may be disposed on the lower rail 112 to be inserted and supported by the first rail inner block 121 .

In addition, the first rail inner block 121 of the first rail 120 may include a 1-1 bearing groove 121b. The 1-1 bearing groove 121b may be disposed adjacent to the upper end of the first rail 120 to extend along a radially inner surface of the first rail 120 . The 1-1 bearing groove 121b may be combined with the 1-2 bearing groove 131 of the central base 130 to be described later to mount and support the first bearing 191 .

On the other hand, the first rail 120 may be formed to have a different height in the longitudinal direction depending on the position in the circumferential direction. Specifically, the first rail 120 may have a first height H1 in the longitudinal direction from one side (left side in the drawing), and from the other side (right side in the drawing) spaced apart from it by a predetermined distance in the circumferential direction in the longitudinal direction. It may have two heights (H2). Here, the second height H2 may be formed to be larger than the first height H1 by a predetermined degree.

Also, the height of the first rail 120 may be gradually increased or decreased in the circumferential direction. That is, assuming that the first height H1 is the minimum height of the first rail 120 and the second height H2 is the maximum height of the first rail 120 , the circumferential direction at the position of the first height H1 is Accordingly, the height of the first rail 120 may gradually increase toward the position of the second height H2. In addition, the height of the first rail 120 may gradually decrease from the position of the second height H2 to the position of the first height H1 in the circumferential direction.

The lower rail groove (121a) is disposed at a position spaced apart from the lower end of the first rail (120) by a predetermined interval, and the 1-1 bearing groove (121b) is spaced apart from the upper end of the first rail (120) by a predetermined interval. When arranged, according to the change in height of the first rail 120 as described above, the interval between the lower rail groove 121a and the 1-1 bearing groove 121b may also be changed according to the position. That is, according to each position in the circumferential direction of the first rail 120, a gap between the lower rail groove 121a and the 1-1 bearing groove 121b may be formed differently. The balance stage 100 of the present embodiment may implement a tilting operation through such a difference in spacing (height).

Also, the lower rail groove 121a and the 1-1 bearing groove 121b on the other side (right side in the drawing) of the first rail 120 may be vertically spaced apart by a second interval G2. The first gap G1 and the second gap G2 may be defined as a distance between the vertical center of the lower rail groove 121a and the vertical center of the 1-1 bearing groove 121b. Here, similarly to the above, the second interval G2 may be formed to be larger than the first interval G1 by a predetermined degree. In addition, the interval between the lower rail groove (121a) and the 1-1 bearing groove (121b) may gradually increase from the position of the first interval (G1) to the position of the second interval (G2) along the circumferential direction, Conversely, the distance between the lower rail groove 121a and the 1-1 bearing groove 121b may gradually decrease from the position of the second interval G2 to the position of the first interval G1 in the circumferential direction. .

11 is a schematic longitudinal cross-sectional view showing the second rail shown in FIG. 4 separated.

Referring to FIG. 11 , the second rail 140 may have a predetermined radius and may be formed to extend in a circular shape. The second rail 140 may have a radially inner surface facing the central axis C, and a radially outer surface facing the opposite side.

If necessary, the second rail 140 may be divided into a plurality of pieces. In this embodiment, a case in which the second rail 140 is divided into a second rail inner block 141 and a second rail outer block 142 is exemplified. The second rail inner block 141 and the second rail outer block 142 may be stacked and assembled vertically to form the second rail 140 .

The second rail inner block 141 of the second rail 140 may include a 2-1 bearing groove 141a. The 2-1 th bearing groove 141a may be disposed adjacent to the lower end of the second rail 140 and formed to extend along a radially inner surface of the second rail 140 . A second bearing 192 may be mounted in the 2-1 bearing groove 141a. Also, gear teeth may be formed on the radially outer surface of the second rail 140 .

According to the above, the second rail 140 may be supported on the central base 130 . That is, the second bearing 192 is fastened to the 2-1 bearing groove 141a formed in the second rail 140 , and the 2-2 bearing formed in the central base 130 in the second bearing 192 again. Since the groove 132 is fastened, the second rail 140 may be supported on the central base 130 via the second bearing 192 . In addition, the second rail 140 may be rotated with respect to the central base 130 via the second bearing 192 .

Also, the second rail inner block 141 of the second rail 140 may include a 3-1 bearing groove 141b. The 3-1 th bearing groove 141b may be disposed adjacent to the upper end of the second rail 140 to extend along the radially inner surface of the second rail 140 . The 3-1 th bearing groove 141b may be combined with the 3-2 th bearing groove 152a of the upper rail 152 to be described later to mount and support the third bearing 193 .

Similar to the first rail 120 described above, the second rail 140 may also be formed to have a different height in the longitudinal direction depending on the position in the circumferential direction. Specifically, the second rail 140 may have a third height H3 in the longitudinal direction from one side (left side in the drawing), and the second rail 140 has a third height H3 in the longitudinal direction from the other side (right side in the drawing) spaced apart from it by a predetermined distance in the circumferential direction. It may have 4 heights (H4). Also, the fourth height H4 may be formed to be larger than the third height H3 by a predetermined degree. The height of the second rail 140 may gradually increase from the position of the third height H3 to the position of the fourth height H4 in the circumferential direction, and in the opposite case, the height of the second rail 140 is gradually increased. can be small

To explain the above concept differently, the 2-1 bearing groove 141a and the 3-1 bearing groove 141b on one side (left side in the drawing) of the second rail 140 are vertically spaced at a third interval (G3). It may be spaced apart, and the 2-1 bearing groove 141a and the 3-1 bearing groove 141b on the other side (right side in the drawing) of the second rail 140 are vertically spaced apart by a fourth interval (G4). can be The third gap G3 and the fourth gap G4 may be defined as a distance between the vertical center of the 2-1 th bearing groove 141a and the vertical center of the 3-1 th bearing groove 141b. . Here, the fourth interval G4 may be formed to be larger than the third interval G3 by a predetermined degree. In addition, from the position of the third interval G3 to the position of the fourth interval G4 along the circumferential direction, the interval between the 2-1 bearing groove 141a and the 3-1 bearing groove 141b gradually increases. Conversely, from the position of the fourth interval (G4) to the position of the third interval (G3) along the circumferential direction, the interval between the 2-1 bearing groove (141a) and the 3-1 bearing groove (141b) is may gradually decrease.

In the above, the third and fourth heights (H3, H4) or the third and fourth intervals (G3, G4) are the same as the first and second heights (H1, H2) or the first and second intervals (G1, G2), or may be different. That is, the third and fourth heights (H3, H4) or the third and fourth intervals (G3, G4) of the second rail 140 are the first and second heights (H1, H2) or the third and fourth heights (H1, H2) of the first rail 120 . It does not need to be the same as the intervals 1 and 2 (G1, G2).

The difference in height between the first rail 120 and the second rail 140 or the gap between the grooves 121a, 121b, 141a, and 141b as described above is the gap between the lower rail 112 and the first bearing 191. , may cause a difference in the interval between the second bearing 192 and the third bearing 193 . That is, according to each position in the circumferential direction, the interval at which the lower rail 112 and the first bearing 191 are vertically spaced apart may appear differently. In addition, according to each position in the circumferential direction, the interval at which the second bearing 192 and the third bearing 193 are vertically spaced apart may appear differently, respectively. In other words, the gap between the lower rail 112 and the first bearing 191 or the second bearing 192 and the third bearing 193 to correspond to the gap of each of the aforementioned grooves 121a, 121b, 141a, 141b. ) may be formed to gradually increase or decrease the interval between them.

Figure 12 is a schematic perspective view showing the central rotation support shown in Figure 1 separated.

Referring to FIG. 12 , the central rotation support unit 160 may be fastened between the lower base 110 and the central base 130 to constrain the rotation of the central base 130 with respect to the lower base 110 . Specifically, one side (lower end) of the central rotation support unit 160 may be fastened to the lower base 110 , and the other side (top) may be fastened to the central base 130 . Accordingly, the central base 130 may be fixed to the lower base 110 despite the rotation of the first rail 120 to limit the rotation.

Specifically, the central rotation support unit 160 may include a central rotation pin 161 having one side inserted into the central base 130 and a support pillar 162 connected and fixed to the lower base 110 .

The central rotation pin 161 may be formed in a rotatable cylindrical shape. The central rotation pin 161 is inserted into the inner periphery of the central base 130, and may be rotatably arranged in place. Preferably, the central rotation pin 161 is formed to extend in the transverse direction, it may be disposed to be inserted into the central base 130 in the transverse direction. Specifically, the central rotation pin 161 may include a central insertion pin 161a that is inserted into the support pillar 162 .

The central insertion pin 161a is formed as a cylinder having a smaller diameter than the central rotation pin 161 , is disposed on one side of the central rotation pin 161 , and may be inserted into the support pillar 162 . For example, if the central rotation pin 161 is divided into an outer surface inserted into the interior of the central base 130, a curved columnar surface, and an inner surface disposed in the open space of the central base 130, the central insertion pin 161a ) may be disposed protruding from the inner surface of the central rotation pin 161 disposed in the transverse direction. Preferably, the central insertion pin (161a) may be disposed on one side of the edge rather than the center of the central rotation pin (161).

Meanwhile, the support pillar 162 may be connected and fixed to the lower base 110 . The support column 163 may include a lower support column 162b extending in the transverse direction and an upper support column 162a extending in the longitudinal direction. The lower support post 162b is connected and fixed to the lower base 110, and the upper support post 162a is disposed on one side of the lower support post 162b, and may be formed to extend upward.

In addition, an insertion pin insertion hole (162a-1) into which the central insertion pin (161a) is inserted may be disposed at the upper end of the upper support column (162a).

The insertion pin insertion hole (162a-1) is formed open at the upper end of the upper support column (162a), is formed open in the lateral direction, the central insertion pin (161a) can be inserted. That is, the central insertion pin (161a) may be disposed to be perpendicular to the longitudinal direction of the upper support column (162a). Accordingly, the central insertion pin 161a may be rotated according to a change in the height of the central base 130 in the state inserted into the upper support pillar 162a.

That is, the central rotation pin 161 is rotatably disposed on the central base 130, and the central insertion pin 161a is rotatably disposed in the insertion pin insertion hole 162a-1 of the upper support post 162a. can The support pillar 162 may be fixedly fixed to the lower base 110 .

More specifically, when the central base 130 is arranged at a low height, the central rotation pin 161 is rotated so that the central insertion pin 161a is arranged on the upper end, and when the central base 130 is arranged at a high height, The central rotation pin 161 may be rotated so that the central insertion pin 161a may be disposed at the lower end. At this time, since the central insertion pin 161a is inserted into the insertion pin insertion hole 162a-1, the central insertion pin 161a can be supported so that the central base 130 does not rotate.

13 is a schematic perspective view showing the upper rotation support shown in FIG. 2 separated.

Referring to FIG. 13 , the upper rotation support unit 170 may be fastened between the lower base 110 and the upper base 150 to constrain the rotation of the upper base 150 with respect to the lower base 110 . Specifically, one side (lower end) of the upper rotation support unit 170 may be fastened to the lower base 110 , and the other side (top) may be fastened to the upper base 150 . Accordingly, despite the rotation of the second rail 140 , the upper base 150 is fixed to the lower base 110 so that the rotation may be limited.

Specifically, the upper rotation support unit 170 is an upper rotation pin 171 having one side inserted into the upper base 150 , a support panel 172 into which one side of the upper rotation pin 171 is inserted, and a lower base 110 . It may include a fixed pillar 173 that is connected and fixed.

The upper rotation pin 171 may be formed in a rotatable cylindrical shape. The upper rotation pin 171 is inserted into the inner periphery of the upper base 150, and may be rotatably arranged in place. Preferably, the upper rotation pin 171 is formed to extend in the transverse direction, it may be inserted into the upper base 150 in the transverse direction. Specifically, the upper rotation pin 171 may include an upper insertion pin 171a inserted and disposed in the support panel 172 .

The upper insertion pin 171a is formed as a cylinder having a smaller diameter than the upper rotation pin 171 , is disposed on one side of the upper rotation pin 171 , and can be inserted into the support panel 172 . For example, if the upper rotation pin 171 is divided into an outer surface inserted into the interior of the upper base 150, a curved columnar surface, and an inner surface disposed in an open space at the center of the upper base 150, the upper insertion pin 171a ) may be disposed protruding from the inner surface of the upper rotary pin 171 disposed in the transverse direction. Preferably, the upper insertion pin (171a) may be disposed on one side of the edge rather than the center of the upper rotation pin (171).

On the other hand, the support panel 172 may have one side connected to the fixed pillar 173 and the other side connected to the upper insertion pin 171a. In detail, the support panel 172 may include a lower support panel 172b connected to the fixed pillar 173 and an upper support panel 172a connected to the upper insertion pin 171a. The lower support panel 172b is formed to have a larger area than the upper support panel 172a so that it can be stably connected to and supported by the fixed pillar 173 . The upper support panel 172a may have a smaller area than the lower support panel 172b, and may include an insertion pin insertion hole 172a-1 at an upper end thereof.

That is, the upper rotation pin 171 is rotatably disposed on the upper base 150, and the upper insertion pin 171a is rotatably disposed in the insertion pin insertion hole 172a-1 of the upper support panel 172a. can The fixing column 173 may be fixedly fixed to the lower base 110 .

That is, the upper rotation pin 171 is rotatably disposed on the upper base 150, and the upper insertion pin 171a is rotatably disposed in the insertion pin insertion hole 172a-1 of the upper support panel 172a. can The fixed pillar 173 and the support panel 172 may be fixedly fixed to the lower base 110 .

More specifically, when the upper base 150 is arranged at a low height, the upper rotation pin 171 is rotated so that the upper insertion pin 171a is arranged on the upper end, and when the upper base 150 is arranged at a high height, The upper rotation pin 171 may be rotated so that the upper insertion pin 171a may be disposed at the lower end. At this time, since the upper insertion pin 171a is inserted into the insertion pin insertion hole 172a-1, it is possible to support the upper insertion pin 171a so that the upper base 150 does not rotate.

Meanwhile, the fixing column 173 may be connected and fixed to the lower base 110 . The fixing column 173 may be formed of a pair of opposing plate-shaped plates. The fixed pillars 173 may be spaced apart from each other by a predetermined distance on one side of the lower plate 111 . A support panel 172 may be inserted and fixed between the pair of fixing pillars 173 . In detail, since only the support panel 172 is not independently connected to the lower base 110, the lower support panel 172b is coupled to the lower base 110 while the fixing pillars 173 support it from both sides, It can be fixed more stably.

14 is an operation diagram of the balance stage shown in FIG. 4 .

Referring to FIG. 14 , in the balance stage 100 of the present embodiment, the arrangement angle of the upper rail 152 may be adjusted according to the rotation positions of the first rail 120 and the second rail 140 . In addition, since an object is disposed on the upper rail 152 via an upper plate (not shown), the angle of arrangement of the object may be appropriately adjusted through this.

Specifically, based on the bar shown in FIG. 14, the interval between the lower rail 112 and the first bearing 191 at the right end is referred to as E1, and the distance between the first bearing 191 and the second bearing 192 is The interval is referred to as M, and the interval between the second bearing 192 and the third bearing 193 is referred to as F1. For reference, the interval E1 between the lower rail 112 and the first bearing 191 corresponds to the above-described interval between the lower rail groove 121a and the 1-1 bearing groove 121b (see FIG. 10 ). ), the interval F1 between the second bearing 192 and the third bearing 193 corresponds to the above-described interval between the 2-1 bearing groove 141a and the 3-1 bearing groove 141b ( 11).

In addition, the gap M between the first bearing 191 and the second bearing 192 is the first bearing 191 and the second bearing groove 131 and the second bearing groove 131 in which the first bearing 191 and the second bearing 192 are fitted. 2-2 corresponds to the gap between the bearing grooves 132 . At this time, the interval between the 1-2 bearing groove 131 and the 2-2 bearing groove 132 corresponds to the thickness of the central base 130, and the central base 130 has the first and second rails 120, 140), since it is formed with a constant thickness and there is no change in thickness, the distance M between the first bearing 191 and the second bearing 192 may be formed to be constant without change.

In this case, the interval between the lower rail 112 (that is, corresponding to the lower rail 112) and the upper rail 152 (that is, corresponding to the third bearing 193) is "E1+M+F1". can be At this time, since the distance M between the first bearing 191 and the second bearing 192 is constant without change, the arrangement angle of the upper rail 152 is between the lower rail 112 and the first bearing 191 . It may be determined by the distance E1 and the distance F1 between the second bearing 192 and the third bearing 193 .

Similarly to the above, in a position spaced apart by a predetermined distance in the circumferential direction from the position of E1, the interval between the lower rail 112 and the first bearing 191 is E2, the second bearing 192 and the third bearing 193 A gap between them may be formed by F2. In addition, here again, on the other side of the position E1 spaced apart by a predetermined distance in the circumferential direction, the distance between the lower rail 112 and the first bearing 191 is E3, the second bearing 192 and the third bearing 193. The gap may be formed by F3. Also, the same as above, the distance M between the first bearing 191 and the second bearing 192 may be formed to be constant without change. The interval between the lower rail 112 and the upper rail 152 at each position may be formed by "E2+M+F2", etc. similarly to the above.

Here, in the balance stage 100 of the present embodiment, the gap between the lower rail 112 and the first bearing 191 may be different depending on the position in the circumferential direction, and the second bearing 192 and the third bearing 193 may be formed. ) may also be formed differently. Accordingly, the above “E1+M+F1” to “E3+M+F3” may be formed differently. For example, “E1+M+F1” may be the largest, and the interval may be smaller in the circumferential direction, so that “E3+M+F3” may be the smallest. In this case, the upper rail 152 to the object may be inclined to a position corresponding to E3.

Meanwhile, the inclination direction may be adjusted by rotation of the first rail 120 and the second rail 140 . For example, when the first rail 120 and the second rail 140 are rotated together in the illustrated state and the position corresponding to E4 is moved clockwise, the inclined direction may also be moved clockwise to correspond thereto. The balance stage 100 of the present embodiment can easily adjust the inclination direction in this way. In addition, the inclination direction may be precisely adjusted through the rotational positions of the first rail 120 and the second rail 140 .

Meanwhile, the inclination angle may be adjusted by rotation of the first rail 120 or the second rail 140 . More specifically, the interval between the lower rail 112 and the first bearing 191 according to the rotational position of the first rail 120 or the second bearing 192 according to the rotational position of the second rail 140 and The inclination angle may be adjusted by the distance between the third bearings 193 .

For example, it is assumed that in the illustrated state, only the first rail 120 is rotated clockwise by a predetermined angle, and the position corresponding to E2 is rotated to the position corresponding to E1. In this case, the distance between the lower rail 112 and the first bearing 191 at the right end shown may be changed from E1 initially to E2 according to the rotation of the first rail 120 . That is, the gap between the lower rail 112 and the first bearing 191 may be reduced. On the other hand, since the second rail 140 is not rotated, the distance between the second bearing 192 and the third bearing 193 may be maintained at F1. Consequently, as the interval between the lower rail 112 and the upper rail 152 at the right end is changed to "E2+M+F1", the arrangement angle of the upper rail 152 or the object may be changed.

In addition, in a manner similar to the above, by changing the rotational position of the first rail 120 or the second rail 140, or by changing the rotational position of the first rail 120 and the second rail 140 as necessary. , various inclination angles can be realized. Here, the change of the inclination angle is implemented by the interval between the lower rail 112 and the first bearing 191 formed to be gradually changed or the interval between the second bearing 192 and the third bearing 193, so a simple operation Despite the manner, it can be adjusted with considerable precision.

Furthermore, according to the stable load-bearing structure, durability is excellent, and malfunctions can also be significantly reduced.

In addition, the balance stage 100 according to embodiments of the present invention operates the operation unit 180 meshed with the outer periphery of the first rail 120 and the second rail 140 to simply and precisely the first rail 120 and the second rail 140 may be rotated. At this time, the operation unit 180 is fixed to the central base 130 , and even if the angle of the central base 130 is changed according to the rotation of the first rail 120 , the operation unit 180 can be moved together. That is, the operation unit 180 can always maintain a meshing state with the first rail 120 and the second rail 140 , and is formed integrally with the first rail 120 and the second rail 140 in the conventional It has the characteristic of occupying less volume compared to that.
