DETAILED DESCRIPTION

[0055] The claimed subject matter is now described with reference to the drawings, wherein like reference numerals are generally used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the claimed subject matter. It may be evident, however, that the claimed subject matter may be practiced without these specific details. In other instances, structures and devices are shown in block diagram form in order to facilitate describing the claimed subject matter.

[0056] An insertion tool 100 may be utilized to assist with positioning seals 300 into a desired location of a target component 302. Use of the insertion tool 100 provides for faster and easier installation of the seal 300. The desired location may be a groove 304, channel, or other seating location of a target component 302. Usage of the insertion tool 100 may assist with installation of any seal 300, such as o-rings, gaskets, bellows, diaphragms, sealing/wiper lips and others without introducing additional compressive forces. The seals 300 may be static or dynamic. Utilization of the insertion tool 100 more evenly distributes internal stresses within the seal 300. The insertion tool 100 also provides for more even placement within the desired location, such as the groove 304. Target components 302 utilizing seals 300, and thus benefiting from the insertion tool 100, may include without limitation, those for shafts, pumps, glands, cylinders, connectors, valves, or other components.

[0057] With reference to the FIGURES, the insertion tool 100 may comprise a base 140 operably connected to a seal lifting portion 108. The seal lifting portion 108 may comprise a surface 110 configured to selectably engage with a seal 300 to move the seal 300 between a lifted position and an unlifted position within the associated groove 304 of the component 302. In another implementation, the surface 110 of the seal lifting portion 108 may be further configured to continuously move the seal 300 between the lifted position and the unlifted position as the insertion tool 100 moves about the perimeter of the target component 302. In some implementations, the operator may utilize the insertion tool 100 for one, two, three or more rotations about the perimeter of the target component 302 to properly seat the seal 300.

[0058] The shape or profile of the seal lifting portion 108 may take any form chosen with sound engineering judgement, and may include without limitation, an angled surface, a ramp surface, a flat surface, an arcuate surface, a frustoconical surface, or other shape. FIGS. 35a-d are top views of cross sections of non-limiting implementations of the seal lifting portion 108. The seal lifting portion 108 may be spherical having a circular cross section (FIG. 35a), cylindrical having a circular cross section (FIG. 35a), substantially trapezoidal (FIG. 35b), semi-cylindrical having a semi-circular cross section (FIG. 35c), substantially triangular (FIG. 35d), some other geometry, or a combination of the same. Accordingly, the surface 110 of the seal lifting portion 108 may take the form of an arc, sphere, angled surface, plurality of angled surfaces, another geometry, or a combination of the same.

[0059] As shown in the FIGURES, the surface 110 of the seal lifting portion 108 may have a thicker portion 114 and a thinner portion 116. The thicker portion 114 may be configured to move the seal 300 to the lifted position. The thinner portion 116 may be configured to guide the seal 300 to the unlifted position in the associated groove 304 of the component 302. As shown in the FIGURES, the seal lifting portion 108 may comprise a surface 110 taking the form of a ramp.

[0060] As the seal 300 is moved between an unlifted position and a lifted position by the thicker portion 114, the seal 300 may be stretched by a percentage below its stress-strain curve. The seal 300 may have a first height, h.sub.1, in an unlifted position, and a second height, h.sub.2, in the lifted position. The first height, h.sub.1, may be greater than the second height, h.sub.2. The thickness of the thicker portion 114, the thinner portion 116, and the desired height h.sub.2 of the stretched seal 300 may be determined by sound engineering judgement. The seal lifting portion may have a surface height SH. The surface height SH may be sized and configured to vary per application depending on the target component 302 and seal 300 type. Depending on the geometry of the seal 300 being positioned in the groove 304 or channel of a target component 302, the seal height SH may change on the insertion tool 100 to effectively move the seal 300 between the lifted and unlifted positions to properly and effectively seat the seal 300 in the groove 304 or channel or other target position.

[0061] The shape or profile of the base 140 may take any form chosen with sound engineering judgement. As shown in the FIGURES, the base 140 may take the form of a linear segment, a triangular prism, a substantially trapezoidal shape, a rectangular prism, an arcuate blended portion, a semi-circular prism, a hexagonal prism, an octagonal prism, or some other geometry, not limited thereto. The internal make-up of the base 140 may take any form chosen with solid engineering judgement, and may be without limitation, solid, hollow, hatched, or honeycombed. With continued reference to the FIGURES, the base 140 may comprise a first end 140a and a second end 140b. The seal lifting portion 108 may be disposed proximate the first end 140a of the base 140. The base 140 may further comprise a rear surface 142 proximate the second end 140b of the base 140. At least a portion of the rear surface 142 may be positioned to directly contact the component 302. By having at least a portion of the rear surface 142 being positioned to directly contact the component 302, the distance between the first end 140a of the base 140 and the second end 140b of the base 140 may be configured to maintain a substantially consistent distance between the seal lifting portion 108 and the associated groove 304 of the component 302. The substantially consistent distance may be determined using sound engineering judgement based on a number of factors including the thickness of the thicker portion of the seal lifting portion 108, the stress-strain curve of the seal 300, and the desired height h.sub.2 of the seal 300 upon being moved into the lifted position.

[0062] In one implementation, as shown in FIGS. 1-18, the base 140,340,440 may be a linear segment. In another implementation, as shown in FIGS. 19-26, the base 140,540 may be a substantially trapezoidal shape, wherein the second end 140b,540b of the base 140,540 has a width greater than a width of the first end 140a,540a of the base 140,540. In yet another implementation, as shown in FIGS. 27-30, the base 140,640 may be a substantially trapezoidal shape, wherein the second end 140b,640b of the base 140,640 has a width greater than a width of the first end 140a,640a of the base 140,640 and the distance between the first end 140a,640a of the base 140,640 and the second end 140b,640b of the base 140,640 is less than that of the implementation shown in FIGS. 19-26.

[0063] In one implementation, the rear surface 142 may be shaped to compliment a geometry of the component 302. For example, as shown in FIGS. 1-18, the rear surface 142,342,442 may be a linear segment to compliment at least a portion of a round, rectangular, or angular component 302. As shown in FIGS. 19-34, the rear surface 142,542,642,742 may be an arcuate shape to compliment a round, curved, or radial component 302. In other implementations, the rear surface 142 may be linear, elliptical, ovoid, angular, or some other geometry depending on the geometry of component 302 to which it may compliment.

[0064] In another implementation, as shown in FIGS. 19-34, a portion of the second end 140b,540b,640b,740b of the base 140,540,640,740 and the rear surface 142,542,642,742 may extend down a height H. In one implementation, the entire base 140 may extend down a height H. The height H of the base 140 or the rear surface 142 of the base 140 may be sized to provide the rear surface 142 a surface area such that at least a portion of the rear surface 142 may be maintained against the component 302. The surface area of the rear surface 142 may be sized to increase the amount of contact between the rear surface 142 and the component 302. An increased amount of contact between the rear surface 142 and the component 302 may provide greater stability when using the insertion tool 100. Greater stability when using the insertion tool 100 may be beneficial when inserting a seal 300 having a high elastic resistance.

[0065] In another implementation, as shown in FIGS. 38-42, the base 140,840 may be disposed proximate a first end 108a of the seal lifting portion 108. In such an implementation, the base 140,840 may further comprise a rear surface 142,842 proximate the first end 140a,840a of the base 140,840. At least a portion of the rear surface 142,842 may be positioned to directly contact the component 302. By having at least a portion of the rear surface 142,842 proximate the first end 140a,840a of the base 140,840 being positioned to directly contact the component 302, the insertion tool 100 may be disposed to be supported by the component 302. As shown in FIGS. 38-42, the rear surface 142,842 may comprise a at least one linear segment, angled segment, curved segment, or a combination of the same disposed to compliment a component 302 having a lip, overhang, another protruding feature, or some other geometry.

[0066] In one example, an insertion tool 100 may be utilized to assist with insertion of electrostatic seals 200 having an elastomer into electrostatic chucks 202. Use of the insertion tool 100 provides for faster and easier installation of the electrostatic seal 200 within a groove 204 of the electrostatic chuck 202 without introducing additional compressive forces. Utilization of the insertion tool 100 more evenly distributes internal stresses within the electrostatic seal 200, and thus, within the elastomer of the electrostatic seal 200.

[0067] The insertion tool 100 may dispose the electrostatic seal 200 within the groove 204 of the electrostatic chuck 202 and simultaneously relieve points of high internal stress. The insertion tool 100 may be hand actuated. In another implementation, the insertion tool 100 may be actuated by machine, robot, or other automated process. In use, the operator (or automated device) may maneuver the insertion tool 100 around a perimeter 210 of the electrostatic chuck 202 at a substantially constant velocity. In use, the electrostatic seal 200 is stretched by a percentage that is below its plastic region on a stress-strain curve but enough to remove any points of high stress. In another implementation, the insertion tool 100 may align the electrostatic seal 200 in a center of the groove 204 and eliminate displacement that could cause premature failures due to higher than desirable compressive forces. The insertion tool 100 is configured to seat the electrostatic seal 200 without additional compressive forces on the elastomer of the electrostatic seal.

[0068] The electrostatic seal 200 may be made up of a variety of materials including, but not limited to, elastomers, fluoropolymers such as polytetrafluoroethylene, hard rubbers, carbon fibers, and other plastic polymers. The insertion tool 100 may also be made up of a variety of materials including, but not limited to, plastics, metals, ceramics, carbon fibers, glass, and other polymers. Further, while the insertion tool 100 disclosed herein has been described, as being used in association with electrostatic seals 200 and electrostatic chucks 202, the insertion tool 100 is also applicable in the placement and insertion of other seals and seal arrangements.

[0069] With references to FIGS. 1-18, an insertion tool 100 may be utilized for placement of an electrostatic seal 200 into a groove 204 of an electrostatic chuck 202. The insertion tool 100 may comprise a first segment 102 comprising a first end 102a and a second end 102b. A second segment 104 may comprise a first end 104a and a second end 104b. The first end 104a of the second segment 104 may be operably connected to the second end 102b of the first segment 102. A third segment 106 may comprise a first end 106a and a second end 106b. The first end 106a of the third segment 106 may be operably connected to the second end 104b of the second segment 104. The first segment 102 may comprise a seal lifting portion 108 configured to selectably engage with an electrostatic seal 200 to move the electrostatic seal 200 between a lifted position and an unlifted position within a groove of an electrostatic chuck 202.

[0070] In one implementation, the first segment 102 may be angularly connected to the second segment 104. For example, the angle formed between the first segment 102 and the second segment 104 may be between about 80 degrees and 100 degrees. In another implementation, the angle may be about 90 degrees. In another implementation, the second segment 104 may be angularly connected to the third segment 106. For example, the angle formed between the second segment 104 and the third segment 106 may be between about 80 degrees and 100 degrees. In another implementation, the angle may be about 90 degrees. In an example implementation, the angle between the second segment 104 and the third segment 106 may correspond to a profile of the electrostatic chuck 202.

[0071] The seal lifting portion 108 may be disposed anywhere along a length L of the first segment 102. As shown in the FIGURES, the seal lifting portion 108 may be proximate the second end 102b of the first segment 102. The first segment may have a cross section of any shape chosen with sound engineering judgment. The cross section may be circular, square, rectangular, triangular, or any other polygonal shape. As shown in the FIGURES, the first segment 102 may have a first surface 132, a second surface 134, a third surface 136, and a fourth surface 138. The seal lifting portion 108 may comprise a surface 110 proximate the first surface 132 of the first segment 102. The surface 110 may take the form of a ramp comprising a thicker portion 114 adjacent to the second surface 134 of the first segment 102. The surface 110 may have a thinner portion 116 adjacent to the fourth surface 138 of the first segment 102. As shown in the FIGURES, the surface 110 increases in thickness from the fourth surface 138 towards the second surface 134 of the first segment 102. The thicker portion 114 may be a lifting end terminating in a lip portion 126, which may dispose the electrostatic seal 200 in its lifted position. The thinner portion 116 may be a placement end configured to guide the electrostatic seal 200 to the unlifted position in the groove 204 of the electrostatic chuck 202.

[0072] With continued reference to the FIGURES, the first segment may further comprise guides 118,120 extending from the first surface 132. The guides 118,120 extend on either side of the surface 110 or ramp. The guides 118,120 are configured to maintain placement of the electrostatic seal 200 against at least a portion of the surface 110 as the insertion tool 100 is moved around the perimeter 210 of the electrostatic chuck 202.

[0073] The first segment 102 may further comprise a protrusion 112 extending from the third surface 136. The protrusion 112 and third surface 136 may define a first groove 122 and a second groove 124 there between. In one implementation, the protrusion 112 may be oppositely disposed from the surface 110 or ramp. The protrusion 112 may provide additional surface area, and thus, rigidity to support the electrostatic seal 200 as it is lifted and travels along the surface 110.

[0074] With reference to the FIGURES, the first segment 102 may have a lower portion 103 extending proximate the second end 102b of the first segment 102 to the second groove 124. The length of the lower portion 103 may correspond to the height from a bottom portion 206 of the electrostatic chuck 202 to the groove 204.

[0075] In yet another implementation, the insertion tool 100 may be one unitary piece. In another implementation, the insertion tool 100 may be two or more pieces. As shown in the FIGURES, the first segment 102 may be separable at some portion along its length. As shown in FIG. 9, the first segment 102 may be separable at a joint above the first guide 118. In another implementation shown in FIG. 10, the first segment 102 may be separable from the second segment 104 such that the joint is proximate the second end 102b of the first segment 102 and the first end 104a of the second segment 104. In yet another implementation as shown in FIG. 11, the first segment 102 may be separable at some point in the seal lifting portion 108. For example, it may be separable at a location of the surface 110 and one of the guides 118,120. FIG. 12 illustrates yet another example where the first segment 102 may be separable adjacent the first guide 118.

[0076] In yet another implementation, the insertion tool 100 may comprise a first segment 102 and a second segment 104. As shown in FIGS. 13-16, for example, the second segment may be shortened in length. As shown in FIGS. 13-15, such an implementation may be one unitary piece. As shown in FIG. 16, such an implementation may be two or more pieces. In another implementation, an insertion tool 100 comprising a first segment 102 and a second segment 104 may be separable at some portion along the length of the first segment 102. In another implementation, an insertion tool 100 comprising a first segment 102 and a second segment 104 may be separable at some point in the seal lifting portion 108 or at a location of the surface 110 and one of the guides 118,120.

[0077] In one implementation, as shown in FIG. 17, the rear surface 208 of the electrostatic chuck 202 may be planar. In this implementation, the electrostatic seal 200 may directly contact the rear surface 208 of the groove 204 once positioned with the insertion tool 100.

[0078] In order to utilize the insertion tool 100 and position an electrostatic seal 200 into the groove 204 of an electrostatic chuck 202, the insertion tool 100 as described herein may be provided. The insertion tool 100 is positioned such that the surface 110 has the thicker portion 114 disposed to the left and the thinner portion 116 disposed to the right. The second segment 104 and third segment 106 may mate against a portion of the electrostatic seal 200. The user lifts the electrostatic seal 200 and positions it against the surface 110. The user may support the insertion tool 100 by supporting the first segment 102 with one hand and the third segment 106 with the other hand. The user then moves the insertion tool 100 along the perimeter 210 of the electrostatic chuck 202. In one implementation, the user moves the insertion tool 100 in a clockwise motion about the perimeter 210 of the electrostatic chuck 202. The user may make a plurality of revolutions around the perimeter 210 with the insertion tool 100. In one implementation, the user may make one, two, three, four, five or six revolutions around the electrostatic chuck 202. In another example implementation, the user makes three revolutions around the electrostatic chuck 202. As revolutions are made, the electrostatic seal 200 is lifted as it travels from the thicker portion 114, across the surface 110 towards the thinner portion 116. After being in the lifted position, the electrostatic seal 200 travels across the surface 110, towards the thinner portion 116 and is disposed in the groove 204 to the unlifted position. As revolutions are made with the insertion tool 100, the internal stresses of the elastomer in the electrostatic seal 200 are relieved.

[0079] In yet another implementation, as shown in FIGS. 19-34, the insertion tool 100 may further comprise an arm 144 comprising a first end 144a and a second end 144b. The arm 144 may be operably connected to a first end 108a of the seal lifting portion 108 proximate the second end 144b of the arm 144. As shown in FIGS. 19-30, the seal lifting portion 108 may be situated between the base 140,540,640 and the arm 144 such that the base 140,540,640 and the arm 144 are configured to maintain placement of the seal 300 against at least a portion of the surface 110 of the seal lifting portion 108. By situating the seal 300 between the base 140,540,640 and the arm 144, the seal 300 may be prevented from inadvertently slipping from the surface 110 of the seal lifting portion 108 during use.

[0080] In such an implementation where the seal lifting portion 108 is situated between the base 140,540,640 and the arm 144, the seal lifting portion 108 may be a height SH such that the surface 110 may be substantially aligned with the associated groove 304 of the component 302 and that the rear surface 142,542,642 of the base 140,540,640 may be substantially aligned with at least a portion of a bottom portion of the component 302.

[0081] In another implementation, as shown in FIGS. 1-18 and 31-34, the seal lifting portion 108 may further comprise guides 118,120 on either side of the surface 110. The guides 118,120 have a thickness greater than the thickness of the thicker portion of the surface 110. The guides 118,120 are configured to maintain placement of the seal 300 against at least a portion of the surface 110 of the seal lifting portion 108.

[0082] In another implementation, as shown in FIGS. 19-30, the arm 144 may be an elbow shape, the first end 144a of the arm 144 being perpendicular to the second end 144b. In one implementation, as shown in FIGS. 31-34, the arm 144 may be a linear segment. In yet another implementation, the arm 144 may be circular, rectangular, triangular, arcuate, T-shaped, V-shaped, or some other geometry.

[0083] In another implementation, as shown in the FIGURES, the arm 144 may further comprise a support surface 145. At least a portion of the support surface 145 may be positioned to directly contact the component 302. In one implementation, as shown in FIGS. 19-30 and FIGS. 36-37, the support surface 145 of the arm 144 may be a grooved portion 145a of the support surface 145 of the arm 144, a depth and height of the groove being determined with sound engineering judgement to mate against the component 302 and to substantially align the surface 110 of the seal lifting portion 108 with the groove 204 of the component 302.

[0084] In yet another implementation, as shown in FIGS. 19-34, the first end 144a of the arm 144 may further comprise a gripping portion 146. In another implementation, as shown in FIGS. 38-42, the second end 140b,840b of the base 140,840, may further comprise a gripping portion 146. The gripping portion 146 may have a surface area sized to provide an operator control of the insertion tool 100. The gripping portion 146 may be rectangular, circular, ovular, triangular, or some other geometry in shape. The surface of the gripping portion 146 may be grooved, have ridges, or be otherwise textured to prevent slipping between the operator and the insertion tool 100 during use.

[0085] As shown in FIGS. 19-34, the gripping portion 146 may comprise a first face 146a and a second face 146b, the first face 146a being opposite the second face 146b. In one implementation, the first face may be directed towards the second end 144b of the arm 144 and the second face 146b may be directed towards the component 302. The second face 146b may be curved to provide an operator additional control. In another implementation, the first and second faces 146a,146b may be parallel to the arm 144. In yet another implementation, one of the first or second faces 146a,146b may be directed up and the other of the first or second faces 146a,146b may be directed down.

[0086] In order to utilize the insertion tool 100 and position a seal 300 into the groove 304 of a component 302, the insertion tool 100 as described herein may be provided. In one implementation, the insertion tool 100 is positioned such that the surface 110 has the thicker portion 114 disposed to the left and the thinner portion 116 disposed to the right. In another implementation, the surface 110 may be a curved or spherical shape having the thicker portion 114 disposed in the center and the thinner portion 116 disposed at both the right and left sides of the surface 110.

[0087] As shown in FIG. 17 and FIGS. 36-37, the base 140, particularly the rear surface 142, may mate against a portion of the component 302. In one implementation, as shown in FIG. 36, the support surface 145 or the grooved portion 145a of the support surface 145 of the arm 144 may mate against a portion of the component 302. The user lifts the seal 300 and positions it against the surface 110. The user may support the insertion tool 100 by supporting the base 140 with both hands. In another implementation, the user may support the insertion tool by supporting the arm 144 or the gripping portion 146 with one hand and the base 140 with the other hand.

[0088] The user then moves the insertion tool 100 along the perimeter of the component 302. In one implementation, the user moves the insertion tool 100 in a clockwise motion about the perimeter of the component 302. In another implementation wherein the thicker portion 114 is disposed in the center of the surface 110, the user may move the insertion tool in either a clockwise or counter-clockwise motion about the perimeter of the component 302. The user may make a plurality of revolutions around the perimeter with the insertion tool 100. In one implementation, the user may make one, two, three, four, five or six revolutions around the component 302. In another example implementation, the user makes three revolutions around the component 302.

[0089] As revolutions are made, the seal 300 is continuously lifted as it travels from the thicker portion 114, across the surface 110 towards the thinner portion 116. Prior to being lifted during a revolution, a portion of the seal 300 has a height h.sub.1. As the seal 300 is being moved into the lifted position, the seal 300 is stretched such that the seal 300 has a height h.sub.2, where h.sub.2 is less than h.sub.1. After being in the lifted position, the seal 300 travels across the surface 110, towards the thinner portion 116 and is disposed in the groove 304 to the unlifted position. Once in the unlifted position, the seal 300 returns substantially to its unstretched state with a height h.sub.1. As revolutions are made with the insertion tool 100, the internal stresses of the elastomer in the seal 300 are relieved and the seal is placed in the groove 304 of the component 302.

[0090] The lifting, stretching, unlifting, and releasing of the seal 300 allow for placement of a seal 300, such as an electrostatic seal 200, within an associated groove 304 of a component 302, such as an electrostatic chuck 202, without the use of compressive forces which may damage the seal 300. An electrostatic seal 200 may have a height h.sub.1 greater than or substantially equal to the height of an associated groove 204 on an electrostatic chuck 202. Use of the insertion tool 100 to stretch the electrostatic seal 200 by a percentage below its stress-strain curve and therefore decreasing its height h.sub.1 to a lesser height h.sub.2 allows the user to position the electrostatic seal 200 within the associated groove 204 where the electrostatic seal 200 will return substantially to its original height h.sub.1 without being harmed.
