Definitions
- the present disclosure relates to an insulting glass unit (IGU) sealing system and method, and more particularly, a window sealing assembly and method having tool utilization and spatial recognition for more uniformly sealing portions of the IGU.
- IGU insulting glass unit
- IGUs Insulating glass units
- a spacer assembly usually comprises a spacer frame extending peripherally about the unit, a sealant material adhered both to the glass lites and the spacer frame, and a desiccant for absorbing atmospheric moisture within the unit.
- the margins or the glass lites are flush with or extend slightly outwardly from the spacer assembly.
- the sealant extends continuously about the spacer frame periphery and its opposite sides so that the space within the IGUs is hermetic. The sealant provides a barrier between atmospheric air and the IGU interior, which blocks entry of atmospheric water vapor.
- sealant is manually applied around a majority of the spacer frame periphery, while leaving a small opening formed through the spacer frame uncovered, or free from sealant.
- the atmospheric air is evacuated and an inert gas is inserted into the space within the IGU.
- a rivet or screw is inserted into the opening, and additional sealant is then applied over the uncovered area.
- Particulate desiccant is typically deposited inside the spacer frame and communicates with air trapped in the IGU interior to remove the entrapped airborne water vapor, and as such, precludes condensation within the unit. Thus, after the water vapor entrapped in the IGU is removed, internal condensation only occurs if the unit fails.
- the sealant over the uncovered area is typically where IGUs have failed because atmospheric water vapor infiltrated the sealant barrier, such as when the new or second pass sealant over the uncovered area is not hot enough to create a bond with the previously applied sealant, the new sealant is applied unevenly, and/or the like. Additionally, the sealant may be applied unevenly when edges of the glass lites are not co-planar, or otherwise uneven.
- One example embodiment of the present disclosure includes a window sealing system for use in sealing insulating glass units (IGUs).
- the sealing system has an articulating arm having a plurality of members and arms to allow movement about multiple axes defined by the articulating arm, and a sealant dispensing apparatus releasably couplable to the articulating arm.
- the sealant dispensing apparatus comprising a pivotable dispensing element for dispensing sealant onto an IGU, and a vision system, coupled to the sealant dispensing apparatus, for monitoring physical properties of the sealant during sealant application.
- Another example embodiment of the present disclosure comprises a method of constructing a window sealing system for use in sealing insulating glass units (IGUs), the method comprising the steps of assembling a sealant dispensing apparatus comprising a releasably couplable element configured to be coupled to an articulating arm and a pivotable dispensing element for dispensing sealant onto an IGU, coupling a vision system to the sealant dispensing apparatus, for monitoring physical properties of the sealant during sealant application, and connecting the vision system, the articulating arm, and the sealant dispensing apparatus to a controller.
- the controller is configured to receive information from the vision system and instruct the articulating arm based upon the information.
- Yet another example embodiment of the present disclosure includes an apparatus for applying a sealant material over an outer surface of an insulating glass unit.
- the apparatus comprising a source of sealant material, a nozzle for dispensing sealant material from the source onto an outer surface of an insulating glass unit, and a valve for regulating sealant flow from the source to the nozzle.
- the apparatus further includes a drive for providing relative movement between the nozzle and the insulating glass unit as the nozzle dispenses sealant onto the outer surface, a controller coupled to the drive for adjusting the drive speed to regulate deposition of sealant onto the insulating glass unit, and a sensor for determining a location of the outer surface to appropriately position the nozzle for dispensing of the sealant.
- While another aspect of the present disclosure includes an apparatus for applying a sealant material over an outer surface of an insulating glass unit.
- the apparatus comprises a source of sealant material; a nozzle for dispensing sealant material from the source onto an outer surface of an insulating glass unit; a valve for regulating sealant flow from the source to the nozzle; a drive for providing relative movement between the nozzle and the insulating glass unit as the nozzle dispenses sealant onto the outer surface; a controller coupled to the drive for adjusting the drive speed to regulate deposition of sealant onto the insulating glass unit; a sensor for determining a location of the outer surface to appropriately position the nozzle for dispensing of the sealant; and a smoothing apparatus coupled to the drive, the smoothing apparatus comprising a heating element, wherein the drive provides relative movement between the smoothing apparatus and the insulating glass unit as the heating element interacts with sealant on the outer surface.

- the sealant dispensing apparatus 14 has a home location having coordinates known by the controller 35. The home location comprises a rack or holder on which the sealant dispensing apparatus 14 rests.
- the articulating arm 62 couples to the sealant dispensing apparatus 14 when it is located at the home location for movement to a dispensing position in relation to the IGU 100. The articulating arm 62 then places the sealant dispensing apparatus at the home location after the sealant 40 has been dispensed.
- the sealant valve 28 is opened by the cylinder 23 to allow sealant 40 from the sealant input 20 to flow through a nozzle 26 and from the dispensing apparatus 14 that programmably moved by the controller 35 (while applying the sealant along the uncovered area 209). Once the uncovered area 209 is covered with sealant 40, the sealant valve 28 is closed stopping sealant from going from the sealant input 20 to the nozzle 26.

- the dispensing head 21 comprises heating elements 31, 32, 33, a flexible attachment hose 30 fluidly coupled to the sealant valve 28, and thus the sealant input 20, the flexible attachment hose runs through the heating elements, a dispensing element 22 comprising a nozzle 26 coupled to the flexible attachment hose for dispensing sealant 40.
- the flexible attachment hose 30 is adjacent the heating elements 31 , 32, 33 to maintain a fluid state of the sealant 40 during application of the sealant to the IGU 100 and maintains a sufficient temperature of the sealant to ensure bonding between the newly applied sealant and the previously manually applied solidified sealant 200.
- the heating elements 31 , 32, 33 maintain a temperature between about 275°F to about 475°F, and the sealant 40, when leaving the nozzle 26, has a temperature above 350°F.
- a front face heating element 51 is present above the nozzle 26 on a front face 24 of the dispensing head 21, wherein the front face heating element further interacts with the sealant 40 during application to maintain the temperature of the sealant between about 275°F to about 475°F. It would be appreciated by one having ordinary skill in the art that though first and second heating elements are nearer the dispensing element 22, and the hose 30 is between the third heating element 33 and the first and second heating elements, multiple heating element configurations are contemplated. For example, having less than or more than three heating elements, having the heating elements together on one or the other side of the hose 30, etc.
- the flexible attachment 30 is buttressed by one or more springs 30A, 30B ⁇ e.g., a coil spring wrapped around the attachment, tensions springs, extension springs, etc.).
- the one or more springs 30A, 30B support the dispensing element 22, and thus the nozzle 26, while allowing the dispensing element 22, the one or more heating elements 31 , 32, and/or the front face heating element 41 to pivot, compress, expand, translate and/or rotate relative to the x-axis, the y-axis, the z-axis and the IGU 100.
- the dispensing element 22 remains flush with front side edges 214 of both the first and second glass lites 210, 212, which prevents the sealant 40 from escaping sideways along the x-axis and past the front side edges.
- the dispensing element 22 does not pivot when coming into contact with the front side edges.
- the dispensing element 22 pivots toward a first direction (arrow A) or a second direction (arrow B), responsive to the first and second lites 210, 212 being uneven along the z, x coordinate plane.
- first direction arrow A
- second direction arrow B
- the dispensing element 22 pivots in the first direction (arrow A) to evenly distribute the sealant 40.
- the dispensing element 22 pivots in the second direction (arrow B) to evenly distribute the sealant 40.
- the dispensing element 22 does not pivot when coming into contact with the front side edges.
- the dispensing element 22 pivots as illustrated in FIGS. 11B-1 1C toward a forward (arrow C) or backward (arrow D) direction to be flush with the front side edges.
- the dispensing element 22 responsive to encountering the glass lites 210, 212 can move along the z-axis (arrow E) to partially shorten the hose 30, to prevent hitting the glass lites with significant force, or to mitigate a force applied to the lites during contact. It would be appreciated by one having ordinary skill in the art that the dispensing element 22 can concurrently pivot along the y, z coordinate plane, the x, z coordinate plane, and x, y coordinate plane to adjust to various positions of the glass lites 210, 212. Thus, the quality of the seal created by the sealant 40 is uniform even when the glass lites 210, 212 are uneven, tilted, or the like.
- the dispensing element 22 comprises the front face 24 in which the nozzle opening 26 is defined.
- the front face 24 terminates in a top face 25 of the dispensing element 22 that extends along a plane at a 90° angle relative to the front face.
- the top face 25 extends along a plane that is transverse to the front face 24. The angle of the top face 25 relative to the front face 24 is configured to capture excess sealant 40 in a bead 38, and to help evenly spread the sealant by acting as a sealant spreader/scraper.
- the smoothing apparatus 41 is coupled to the sealant dispensing apparatus 14 via an arm 43.
- the smoothing apparatus 41 comprises a smoothing element 45 coupled to a front face 47 of the smoothing element.
- the front face 24 of the nozzle 26 is coplanar with the front face 47, the smoothing element 45, or extends in front of the front face of the nozzle in a direction away from the tool connector 18.
- the smoothing element reaches a temperature between about 275°F to about 475°F.
- the arm 43 comprises a flexible attachment that functions in a same or similar manner as the flexible attachment 30 that supports the dispensing element.
- the arm 43 supports the smoothing apparatus 41 as it pivots, compresses, expands, translates and/or rotates relative to the x-axis, the y-axis, the z-axis and the IGU 100, responsive to the alignment of the first side edges 214 of both the first and second glass lites 210, 212.
- the vision system 12 is coupled to the sealant dispensing apparatus 14, such that a beam 34 emitted from the vision system interacts with the top face 25 of the nozzle 26, and/or the bead 38.
- the vision system 12 comprises a laser vision system and/or an infrared vision system, wherein the vision system emits a laser or an infrared beam and determines a physical property of the bead 38 by capturing refracted/reflected light after the light had interacted with the bead.
- the size of the bead 38 and/or the temperature of the bead is determined and communicated to the controller 35 during use to control the speed or movement of the arm 62 and/or dispensing of the sealant 40 to apply a controlled amount of sealant along the uncovered area 209.
- the coordinates of the uncovered area 209 are determined by the optical sensor 16, the articulating arm 62 will couple to the tool connector 18, to couple the sealant dispensing apparatus 14 to the arm.
- a first sealant dispensing apparatus 14 or a second sealant dispensing apparatus will be selected based upon a width of the IGU, wherein the first and second sealant dispensing apparatuses have different nozzles 26, having different widths and/or dimensions configured to interact with a given IGU 100 of a plurality of IGUs, the IGU having a particular width.
- the articulating arm 62 will move the sealant dispensing apparatus 14 such that the smoothing apparatus 41 abuts the IGU 100 over the uncovered area 209.
- method step 304a is optional, and performed when the optical sensor 16 detects the lump or bump. In another example embodiment, method step 304a is performed whether the optical sensor 16 detects the lump or bump or does not detect such an imperfection.
- the nozzle 26 is aligned at a first or second end 209a, 209b, respectively, of the uncovered area 209, where the sealant 200 is present but not of sufficient thickness, or not present (see FIG. 13). It would be appreciated by one having ordinary skill in the art, that though IGUs 100 having double pane glass is shown, multi-pane IGUs (e.g., such as triple pane windows having two spacer frames and three glass lites) are contemplated and would be sealed in a same manner as the double pane IGUs.
- the nozzle 26 is aligned to dispense sealant 40 beginning at the second end 209b (see FIG. 13).
- the nozzle 26, once aligned starts dispensing sealant 40 while moving along the edges of the first and second lites 210, 212, in a first dispensing direction (arrow F) along the y-axis.
- excess sealant 40 forms the bead 38.
- the vision system 12 detects physical properties of the bead 38.
- the application of the sealant 40 is altered based upon the physical properties of the bead 38, for example, if the bead is too big, the controller 35 will determine that too much sealant 40 is being dispensed or the sealant dispensing apparatus 14 is moving too slowly. In such instances, the controller 35 will adjust one of the flow speed of the sealant, or increase the speed at which the sealant dispensing apparatus 14 is moving. In another example, if the bead 38 is too small, the controller 35 will determine that too little sealant 40 is being dispensed or the sealant dispensing apparatus 14 is moving too quickly for optimal sealant deposition.
- the controller 35 will increase one of the flow speed of the sealant, or decrease the speed at which the sealant dispensing apparatus 14 is moving.
- the controller will alter the heat being applied by the heating elements 31 , 32, 33, increase the flow rate of the sealant 40 (e.g., by increasing the pressure on the sealant in the sealant dispensing apparatus 14), and/or increase the speed at which the sealant dispensing apparatus 14 is moving along the dispensing direction (arrow F).
- the controller 35 instructs the sealant dispensing apparatus 14 to stop dispensing sealant 40.
- the sealant dispensing apparatus 14 stops dispensing sealant 40 gradually, or abruptly, responsive to the information sent to the controller 35.
- the sealant dispensing apparatus 14 continues moving along the edges of the first and second lites 210, 212, in the first dispensing direction (arrow F) after the sealant dispensing apparatus has stopped dispensing sealant 40. In one example embodiment, the sealant dispensing apparatus 14 continues moving along the edges of the first and second lites 210, 212 for a predetermined distance (e.g., a distance equal to the length of the dispensing apparatus 22).
- the sealant dispensing apparatus 14 continues moving along the edges of the first and second lites 210, 212 until the controller 35 receives information from the vision system 12 that the bead 38 has shrunk or disappeared. In this way, the dispensing apparatus 22 wipes/cleans itself before returning to step 302.
- the sealant dispensing apparatus is removed from the IGU 100 once the sealant has been dispensed, for example, responsive to the coordinates indicating the sealant dispensing apparatus 14 has reached the first end 209a, the nozzle 26 stops dispensing sealant 40 (e.g., by the controller 34 instructing the cylinder 21 to extend to close the sealant valve 28).
- the front face 24 of the dispensing element 22 maintains contact with the edges of the IGU 100 and continues moving along the dispensing direction (arrow F) until the vision system 12 indicates that the bead 38 is a stop dispensing size (e.g., as indicated by a pre-programmed variable in the controller 35).
- the controller 35 instructs the articulating arm 62 to continue moving the sealant dispensing apparatus 14 along the dispensing direction (arrow F) until receiving a signal from the vision system 12 to remove the sealant dispensing apparatus 14 from contact with the IGU 100.
- the movement of the sealant dispensing apparatus 14 along the dispensing direction (arrow F) smoothes the remaining sealant 40 to create an even seal.
- the sealant dispensing apparatus 14 is returned to the home position and uncoupled from the articulating arm 62.
- sealant dispensing apparatus 14 could be moved from the first end 209a to the second end 209b, such as in a second dispensing direction directly opposed to the dispensing direction (arrow F) to dispense sealant 40.
- the articulating arm 62 will couple to the tool connector 18, to couple the sealant dispensing apparatus 14 to the arm.
- the articulating arm 62 will move the sealant dispensing apparatus 14 to abut the IGU 100 as described above with regard to step 304 of the example method 300 illustrated in FIG. 15.
- the nozzle 26 is aligned at an initial position to dispense sealant 40 beginning at the second end 209b ⁇ see FIG. 13).
- the vision system 12 monitors a size of the bead 38 and communicates the size to the controller 35.
- the controller 35 instructs the sealant dispensing apparatus 14 to stop dispensing sealant 40.
- the sealant dispensing apparatus 14 stops dispensing sealant 40 abruptly, responsive to the information sent to the controller 35.
- the sealant dispensing apparatus 14 starts moving along the edges of the first and second lites 210, 212, maintaining contact with the edges.
- the sealant dispensing apparatus 14 moves in the first dispensing direction (arrow F) after the sealant dispensing apparatus has stopped dispensing sealant 40.
- the sealant dispensing apparatus 14 continues moving along the edges of the first and second lites 210, 212 for a predetermined distance (e.g., a distance equal to the length of the dispensing apparatus 22).
- the sealant dispensing apparatus 14 continues moving along the edges of the first and second lites 210, 212 until the controller 35 receives information from the vision system 12 that the bead 38 has shrunk or disappeared. In this way, the dispensing apparatus 22 wipes/cleans itself before returning to step 402.
- the sealant dispensing apparatus is removed from the IGU 100.
- the articulating arm 62 coupled to the sealant dispensing apparatus 14 dispenses the sealant in a reproducible manner.
- the articulating arm 62 moves the sealant dispensing apparatus 14 at a constant speed, unless the visions system 12 indicates that the speed should be adjusted to achieve a more uniform sealant dispensing.
- the vision system 12 is able to adjust dispensing factors, such as sealant temperature, sealant dispensing speed, and the speed of the sealant dispensing apparatus 14, during application to prevent dis-uniformity across multiple IGUs.
- the real-time monitoring by the vision system 12 provides enhanced sealing of the IGUs.
- a user may move the sealant dispensing apparatus 14 too quickly, preventing bonding of the steady state sealant 200 and the sealant 40, or too slowly resulting in overflow of the sealant.
- the pivotablity of the dispensing element 22 further enhances sealing of the IGUs 100, by allowing the front face 24 of the dispensing element to be flush with the edges of the IGU 100. It should be appreciated that while the IGU 100 is being presented to the sealing system 10 with a first sealant 40 along all sides of the IGU except for the unsealed area 209.
- the sealing system 10 however has the flexibility and designed in such a way that the system can apply sealant to more than the unsealed area 209 and along all sides of the IGU if desired.
- Coupled as used herein is defined as connected or in contact either temporarily or permanently, although not necessarily directly and not necessarily mechanically.
- a device or structure that is “configured” in a certain way is configured in at least that way, but may also be configured in ways that are not listed.
