APPARATUSES, SYSTEMS, AND METHODS FOR APPLYING A VISCOUS MATERIAL

BACKGROUND

The application of a viscous material onto a surface of a workpiece is a routine step of the process for manufacturing a variety of components. The viscous material may be a sealant or an adhesive used to adhere the workpiece to another component. Structural performance of the viscous material depends on proper distribution of the viscous material onto the workpiece, which is difficult to achieve with conventional applicator tips.

SUMMARY

Accordingly, apparatuses and methods, intended to address at least the above-identified concerns, would find utility.

The following is a non-exhaustive list of examples, which may or may not be claimed, of the subject matter according the present disclosure.

One example of the present disclosure relates to an apparatus for applying a viscous material to a surface of a workpiece. The apparatus comprises a channel comprising an inlet and an outlet. The channel has a width CW that increases from the inlet to the outlet. The apparatus also comprises dividers inside the channel. The channel further comprises subdivisions formed by the divider. The subdivisions of the channel are in communication with the inlet and the outlet of the channel. At least one of the subdivisions of the channel has a width SW that increases from the inlet of the channel to the outlet of the channel.

Another example of the present disclosure relates to a system for applying a viscous material to a surface of a workpiece. The system comprises a channel comprising an inlet and an outlet. The channel has a width CW that increases from the inlet to the outlet. The system also comprises dividers inside the channel. The channel further comprises subdivisions formed by the dividers. The subdivisions of the channel are in communication with the inlet and the outlet of the channel. At least one of the subdivisions of the channel has a width SW that increases from the inlet of the channel to the outlet of the channel. The system further comprises a material supply device coupled to the channel. The material supply device is configured to supply the viscous material to the channel.

Illustrative, non-exhaustive examples, which may or may not be claimed, of the subject matter according the present disclosure are provided below.

Referring e.g. to FIGS. 1-18, apparatus 102 for applying viscous material 162 to surface 182 of workpiece 180 is disclosed. Apparatus 102 comprises channel 104 comprising inlet 106 and outlet 108. Channel 104 has width CW that increases from inlet 106 to outlet 108. Apparatus 102 also comprises dividers 110 inside channel 104. Channel 104 further comprises subdivisions 112 formed by dividers 110. Subdivisions 112 of channel 104 are in communication with inlet 106 and outlet 108 of channel 104. At least one of subdivisions 112 of channel 104 has width SW that increases from inlet 106 of channel 104 to outlet 108 of channel 104. The preceding subject matter of this paragraph characterizes example 1 of the present disclosure.

Apparatus 102 improves the ease and accuracy of applying a wide layer of viscous material 162 having a uniform thickness onto surface 182 of workpiece 180. More specifically, as viscous material 162 passes through channel 104, dividers 110 evenly distribute viscous material 162 across width CW of channel 104 such that viscous material 162 at outlet 108 of channel 104 has a predetermined width and uniform thickness. Dividers 110 spread viscous material 162 laterally outwardly to uniformly fill width CW of channel 104 as width CW increases. By facilitating the application onto surface 182 of workpiece 180 of a wide layer of viscous material 162 with a uniform thickness, apparatus 102 reduces time, effort, and inconsistency associated with covering relatively large areas of surface 182 of workpiece 180 with viscous material 162. Viscous material 162 can be any of various viscous materials, such as adhesives, sealants, paints, and the like.

Referring generally to FIG. 1 and particularly to e.g. FIGS. 2, 3, and 5-8, channel 104 has volume CV and cross-sectional area CA. Volume CV is adjustable to any one of first volumetric values or any one of second volumetric values. Cross-sectional area CA of channel 104 increases from inlet 106 of channel 104 to outlet 108 of channel 104 when volume CV of channel 104 is held constant at any of at least one of the first volumetric values. Each of subdivisions 112 of channel 104 has volume SV. Volume SV of each of subdivisions 112 is adjustable to any one of third volumetric values. Each of the third volumetric values is less than each of the first volumetric values or each of the second volumetric values. At least one of subdivisions 112 of channel 104 also has cross-sectional area SA that increases from inlet 106 of channel 104 to outlet 108 of channel 104 when volume CV of channel 104 is held constant at any of at least one of the second volumetric values. The preceding subject matter of this paragraph characterizes example 2 of the present disclosure, wherein example 2 includes the subject matter of example 1, above.

Adjustability of volume CV of channel 104 and volume SV of each of subdivisions 112 facilitates adjustment of the thickness of viscous material 162 at outlet 108 of channel 104. Additionally, volume CV of channel 104 and volume SV of each of subdivisions 112 is adjustable to accommodate the use of viscous materials with different viscosities.

Referring generally to FIG. 1 and particularly to e.g. FIGS. 2, 3, and 5-8, the second volumetric values are different from the first volumetric values. The preceding subject matter of this paragraph characterizes example 3 of the present disclosure, wherein example 3 includes the subject matter of example 2, above.

The configuration of dividers 110 and subdivisions 112 may be such that for some volumetric values of volume CV of channel 104, cross-sectional area CA of channel 104 is increasing, while cross-sectional area SA of at least one of subdivisions 112 may not be increasing. In other words, an increasing cross-sectional area CA of channel 104 does not necessarily mean an increasing cross-sectional area SA of all of subdivisions 112.

Referring generally to FIG. 1 and particularly to e.g. FIGS. 2, 3, and 5-8, channel 104 has volume CV and cross-sectional area CA. Volume CV is adjustable to any one of first volumetric values or any one of second volumetric values. Cross-sectional area CA of channel 104 stays constant from inlet 106 of channel 104 to outlet 108 of channel 104 when volume CV of channel 104 is held constant at any of at least one of the first volumetric values. Each of subdivisions 112 of channel 104 has volume SV. Volume SV of each of subdivisions 112 is adjustable to any one of third volumetric values. Each of the third volumetric values is less than each of the first volumetric values or each of the second volumetric values. At least one of subdivisions 112 of channel 104 also has cross-sectional area SA that stays constant from inlet 106 of channel 104 to outlet 108 of channel 104 when volume CV of channel 104 is held constant at any of at least one of the second volumetric values. The preceding subject matter of this paragraph characterizes example 4 of the present disclosure, wherein example 4 includes the subject matter of example 1, above.

Referring generally to FIG. 1 and particularly to e.g. FIGS. 2, 3, and 5-8, the second volumetric values are different from the first volumetric values. The preceding subject matter of this paragraph characterizes example 5 of the present disclosure, wherein example 5 includes the subject matter of example 4, above.

The configuration of dividers 110 and subdivisions 112 may be such that for some volumetric values of volume CV of channel 104, cross-sectional area CA of channel 104 is constant, while cross-sectional area SA of at least one of subdivisions 112 may not be constant. In other words, a constant cross-sectional area CA of channel 104 does not necessarily mean a constant cross-sectional area SA of all of subdivisions 112.

Referring generally to FIG. 1 and particularly to e.g. FIGS. 2, 3, and 5-8, channel 104 has volume CV and cross-sectional area CA. Volume CV is adjustable to any one of first volumetric values or any one of second volumetric values. Cross-sectional area CA of channel 104 decreases from inlet 106 of channel 104 to outlet 108 of channel 104 when volume CV of channel 104 is held constant at any of at least one of the first volumetric values. Each of subdivisions 112 of channel 104 has volume SV. Volume SV of each of subdivisions 112 is adjustable to any one of third volumetric values. Each of the third volumetric values is less than each of the first volumetric values or each of the second volumetric values. At least one of subdivisions 112 of channel 104 also has cross-sectional area SA that decreases from inlet 106 of channel 104 to outlet 108 of channel 104 when volume CV of channel 104 is held constant at any of at least one of the second volumetric values. The preceding subject matter of this paragraph characterizes example 6 of the present disclosure, wherein example 6 includes the subject matter of example 1, above.

Referring generally to FIG. 1 and particularly to e.g. FIGS. 2, 3, and 5-8, the second volumetric values are different from the first volumetric values. The preceding subject matter of this paragraph characterizes example 7 of the present disclosure, wherein example 7 includes the subject matter of example 6, above.

The configuration of dividers 110 and subdivisions 112 may be such that for some volumetric values of volume CV of channel 104, cross-sectional area CA of channel 104 is decreasing, while cross-sectional area SA of at least one of subdivisions 112 may not be decreasing. In other words, a decreasing cross-sectional area CA of channel 104 does not necessarily mean a decreasing cross-sectional area SA of all of subdivisions 112.

Referring generally to FIG. 1 and particularly to e.g. FIGS. 3 and 5-8, dividers 110 are located partially outside channel 104. The preceding subject matter of this paragraph characterizes example 8 of the present disclosure, wherein example 8 includes the subject matter of any of examples 1-7, above.

Locating dividers 110 partially outside channel 104 allows dividers 110 to remain inside channel 104 as volume CV of channel 104 changes. Additionally, locating dividers 110 partially outside channel 104 provides ability to fix dividers 110 independently of channel 104 to facilitate adjustment of volume CV of channel 104 relative to dividers 110.

Referring generally to FIG. 1 and particularly to e.g. FIGS. 2, 3, 5-14, and 18, apparatus 102 further comprises flow regulator 130 at least partially defining channel 104. The preceding subject matter of this paragraph characterizes example 9 of the present disclosure, wherein example 9 includes the subject matter of any of examples 1-8, above.

Referring generally to FIG. 1 and particularly to e.g. FIGS. 2, 3, and 5-8, flow regulator 130 comprises flap 136. The preceding subject matter of this paragraph characterizes example 10 of the present disclosure, wherein example 10 includes the subject matter of example 9, above.

Flap 136 facilitates changing volume CV of channel 104 and cross-sectional area OA of outlet 108. Adjustment of flap 136 may not change width CW of channel 104.

Referring generally to FIG. 1 and particularly to e.g. FIGS. 2, 3, and 5-8, apparatus 102 further comprises wall 126 at least partially defining channel 104. Flap 136 comprises first end 138 coupled to wall 126 at inlet 106 of channel 104 and second end 140 at outlet 108 of channel 104. The preceding subject matter of this paragraph characterizes example 11 of the present disclosure, wherein example 11 includes the subject matter of example 10, above.

By extending from first end 138 at inlet 106 of channel 104 to second end 140 at outlet 108 of channel 104, flap 136 defines a portion of channel 104 extending from first end 138 to second end 140. In this manner, adjustment of flap 136 changes cross-sectional area of channel 104 at each location of channel 104 between inlet 106 and outlet 108 of channel. Additionally, with second end 140 of flap 136 at outlet 108 of channel 104, flap 136 at least partially defines outlet 108 of channel 104. Accordingly, adjustment of flap 136 correspondingly changes cross-sectional area OA of outlet 108.

Referring generally to FIG. 1 and particularly to e.g. FIGS. 2, 3, and 5-8, first end 138 of flap 136 is hinged to wall 126 of channel 104. The preceding subject matter of this paragraph characterizes example 12 of the present disclosure, wherein example 12 includes the subject matter of example 11, above.

Hinging first end 138 of flap 136 to wall 126 of channel 104 facilitates adjustment of flap 136 relative to wall 126. Flap 136 may rotate about hinged connection between flap 136 and wall 126. Further, the hinged connection between flap 136 and wall 126 at inlet 106 of channel 104 may facilitate adjustment of cross-sectional area OA of outlet 108 of channel while holding constant a cross-sectional area of inlet 106 of channel 104.

Referring generally to FIG. 1 and particularly to e.g. FIGS. 2, 3, and 5-8, apparatus 102 further comprises actuator 144 coupled to flap 136. Actuator 144 is configured to move at least a portion of flap 136 relative to dividers 110. The preceding subject matter of this paragraph characterizes example 13 of the present disclosure, wherein example 13 includes the subject matter of any of examples 11 or 12, above.

Actuator 144 is actuatable to induce movement of flap 136. Moving at least a portion of flap 136 relative to dividers 110 provides ability to fix dividers 110 independently of channel 104 to facilitate adjustment of volume CV of channel 104 relative to dividers 110.

Referring generally to FIG. 1 and particularly to e.g. FIGS. 2, 3, and 5-8, actuator 144 comprises riser 146 fixed to flap 136. Actuator 144 also comprises knob 148 movably engaging riser 146. Wall 126 is interposed between flap 136 and knob 148 and comprises opening 128 through which riser 146 extends. Knob 148 is movable relative to riser 146 for exerting equal and opposite forces on riser 146 and wall 126 to move riser 146 and flap 136 relative to dividers 110. Riser 146 is configured to move through opening 128 in wall 126. The preceding subject matter of this paragraph characterizes example 14 of the present disclosure, wherein example 14 includes the subject matter of example 13, above.

Flap 136 is movable relative to dividers 110 by moving knob 148 relative to riser 146. Knob 148 can be rotated in one direction to move flap 136 in a first direction and rotated in another direction to move flap 136 in a second direction opposite the first direction. The first direction may be associated with increasing volume CV and cross-sectional area CA of channel 104. The second direction may be associated with decreasing volume CV and cross-sectional area CA of channel 104. Riser 146 may be an externally threaded rod and knob 148 may be an internally threaded nut threadably engaged with the threaded rod in one embodiment.

Referring generally to FIG. 1 and particularly to e.g. FIGS. 2, 5, and 6, flap 136 comprises slots 142. Each divider 110 passes through a respective one of slots 142. The preceding subject matter of this paragraph characterizes example 15 of the present disclosure, wherein example 15 includes the subject matter of any of examples 10-14, above.

Passing each divider 110 through a respective one of slots 142 of flap 136 provides ability to fix dividers 110 independently of flap 136 to facilitate adjustment of volume CV of channel 104 relative to dividers 110. The size and shape of slots 142 may complement size and shape of dividers 110 to inhibit flow of viscous material 162 between respective slots 142 and dividers 110 and retain viscous material 162 in channel 104.

Referring generally to FIG. 1 and particularly to e.g. FIGS. 2, 3, 5, and 6, flap 136 has width FW equal to width CW of channel 104 at corresponding locations between inlet 106 and outlet 108 of channel 104. The preceding subject matter of this paragraph characterizes example 16 of the present disclosure, wherein example 16 includes the subject matter of any of examples 10-15, above.

Width FW of flap 136 being equal to width CW of channel 104 allows flap 136 to define an entire side of channel 104. In this manner, adjustment of flap 136 may result in a uniform change in a height of channel 104 across width CW of channel 104.

Referring generally to FIG. 1 and particularly to e.g. FIGS. 2, 3, 5-14, and 18, outlet 108 of channel 104 has area OA that is adjustable. The preceding subject matter of this paragraph characterizes example 17 of the present disclosure, wherein example 17 includes the subject matter of any of examples 1-16, above.

Adjustability of area OA of outlet 108 of channel 104 facilitates adjustment of the thickness of viscous material 162 at outlet 108 of channel 104. The thickness of viscous material 162 at outlet 108 of channel 104 may control thickness 166 of layer 164 of viscous material 162 applied onto surface 182 of workpiece 180.

Referring generally to FIG. 1 and particularly to e.g. FIGS. 2, 3, 5-14, and 18, apparatus 102 further comprises flow regulator 130 at least partially defining channel 104. Outlet 108 of channel 104 has area OA that is adjustable. The preceding subject matter of this paragraph characterizes example 18 of the present disclosure, wherein example 18 includes the subject matter of example 1, above.

Flow regulator 130 facilitates the regulation of the flow of viscous material 162 through channel 104. More specifically, the flow of viscous material 162 through channel 104 may be adjusted by adjustment of flow regulator 130. Adjustment of the flow of viscous material 162 through channel 104 facilitates changing the characteristics of layer 164 of viscous material 162 applied to surface 182 of workpiece 180 by apparatus 102. Adjustability of area OA of outlet 108 of channel 104 facilitates adjustment of the thickness of viscous material 162 at outlet 108 of channel 104. The thickness of viscous material 162 at outlet 108 of channel 104 may control thickness 166 of layer 164 of viscous material 162 applied onto surface 182 of workpiece 180.

Referring generally to FIG. 1 and particularly to e.g. FIGS. 9-14 and 18, channel 104 has volume CV that is constant. Each of subdivisions 112 has volume SV that is constant. The preceding subject matter of this paragraph characterizes example 19 of the present disclosure, wherein example 19 includes the subject matter of example 18, above.

Characteristics of layer 164 of viscous material 162 applied to surface 182 of workpiece 180 may be changed by holding volume CV of channel 104 and volume SV of subdivisions constant, while adjusting area OA of outlet 108 of channel 104.

Referring generally to FIG. 1 and particularly to e.g. FIGS. 9-14 and 18, apparatus 102 further comprises wall 126 at least partially defining channel 104. Flow regulator 130 comprises gate 150 at outlet 108. Gate 150 is movable relative to wall 126 to adjust area OA of outlet 108. The preceding subject matter of this paragraph characterizes example 20 of the present disclosure, wherein example 20 includes the subject matter of example 19, above.

Gate 150 facilitates changing cross-sectional area OA of outlet 108. Movement of gate 150 relative to wall 126 may not change width CW or volume CV of channel 104. Area OA of outlet 108 may be adjusted by sliding gate 150 relative to wall 126. Apparatus 102 may include body 120 with grooves 152. Gate 150 may include tongues 156 each configured to complement a respective one of grooves 152. Engagement between respective grooves 152 of body 120 and tongues of gate 150 facilitate movable coupling between gate 150 and body 120. In some embodiments, gate 150 may include grooves 152 and body 120 may include tongues. Coupling arrangements other than tongue-and-groove, such as rack-and-pinion systems, may be used.

Referring generally to FIG. 1 and particularly to e.g. FIGS. 9-12, apparatus 102 further includes means 154 for selectively securing gate 150 in different positions relative to wall 126 to adjust area OA of outlet 108. The preceding subject matter of this paragraph characterizes example 21 of the present disclosure, wherein example 21 includes the subject matter of example 20, above.

Means 154 facilitates ease in temporarily fixing a position of gate 150 relative to wall 126, and thus area OA of outlet 108. More specifically, means 154 is adjustable to either allow or prevent relative movement between gate 150 and wall 126. Means 154 can be at least one set screw that passes through wall 126 and is tightenable against gate 150 to temporarily fix a position of gate 150 relative to wall 126. Means 154 can include other coupling arrangements, such as, but not limited to, pins, clips, locks, interference fits, and the like, that facilitate temporarily fixing a position of gate 150 relative to wall 126.

Referring generally to FIG. 1 and particularly to e.g. FIGS. 7-9 and 12-18, apparatus 102 further comprises curved leading surface 114 extending from outlet 108. The preceding subject matter of this paragraph characterizes example 22 of the present disclosure, wherein example 22 includes the subject matter of any of examples 1-21, above.

Curved leading surface 114 facilitates ease in moving apparatus 102 along surface 182 of workpiece 180 while apparatus 102 applies viscous material 162 to surface 182 of workpiece 180. Additionally, curved leading surface 114 promotes ease in adjusting an orientation of apparatus 102 relative to surface 182 of workpiece 180. Adjustment of the orientation of apparatus 102 relative to surface 182 may be accomplished by rotating apparatus 102 relative to surface 182 about curved leading surface 114 while curved leading surface is in contact with surface 182. Adjusting the orientation of apparatus 102 relative to surface 182 in this manner may change thickness 166 of layer 164 of viscous material 162 applied onto surface 182.

Referring generally to FIG. 1 and particularly to e.g. FIGS. 7-9 and 12-18, curved leading surface 114 has a constant radius of curvature. The preceding subject matter of this paragraph characterizes example 23 of the present disclosure, wherein example 23 includes the subject matter of example 22, above.

Constant radius of curvature of curved leading surface 114 promotes predictability and uniformity of the change in orientation of apparatus 102 relative to surface 182 as apparatus 102 is rotated relative to surface 182 about curved leading surface 114.

Referring generally to FIG. 1 and particularly to e.g. FIG. 18, apparatus 102 further comprises at least one standoff 190 outside channel 104. Standoff 190 protrudes distance D from outlet 108. The preceding subject matter of this paragraph characterizes example 24 of the present disclosure, wherein example 24 includes the subject matter of any of examples 1-23, above.

Standoffs 190 promote placement of apparatus 102 in a predetermined position relative to surface 182 of workpiece 180. More specifically, contact between standoffs 190 and surface 182 of workpiece 180 ensures outlet 108 of channel 104 is predetermined distance D away from surface 182 of workpiece 180. Apparatus 102 includes at least one standoff 190. In some embodiments, apparatus 102 includes at least two standoffs 190. In yet some embodiments, apparatus 102 includes at least four standoffs 190.

The preceding subject matter of this paragraph characterizes example 25 of the present disclosure.

System 100 improves the ease and accuracy of applying a wide layer of viscous material 162 having a uniform thickness onto surface 182 of workpiece 180. More specifically, as viscous material 162 passes through channel 104, dividers 110 evenly distribute viscous material 162 across width CW of channel 104 such that viscous material 162 at outlet 108 of channel 104 has a predetermined width and uniform thickness. Dividers 110 spread viscous material 162 laterally outwardly to uniformly fill width CW of channel 104 as width CW increases. By facilitating the application onto surface 182 of workpiece 180 of a wide layer of viscous material 162 with a uniform thickness, system 100 reduces time, effort, and inconsistency associated with covering relatively large areas of surface 182 of workpiece 180 with viscous material 162.

Flow regulator 130 facilitates the regulation of the flow of viscous material 162 through channel 104. More specifically, the flow of viscous material 162 through channel 104 may be adjusted by adjustment of flow regulator 130. Adjustment of the flow of viscous material 162 through channel 104 facilitates changing the characteristics of layer 164 of viscous material 162 applied to surface 182 of workpiece 180 by system 100. Adjustability of area OA of outlet 108 of channel 104 facilitates adjustment of the thickness of viscous material 162 at outlet 108 of channel 104.

Curved leading surface 114 facilitates ease in moving system 100 along surface 182 of workpiece 180 while system 100 applies viscous material 162 to surface 182 of workpiece 180. Additionally, curved leading surface 114 promotes ease in adjusting an orientation of channel 104 relative to surface 182 of workpiece 180. Adjustment of the orientation of channel 104 relative to surface 182 may be accomplished by rotating channel 104 relative to surface 182 about curved leading surface 114 while curved leading surface is in contact with surface 182. Adjusting the orientation of channel 104 relative to surface 182 in this manner may change thickness 166 of layer 164 of viscous material 162 applied onto surface 182.

Referring generally to FIG. 1 and particularly to e.g. FIGS. 7-9 and 12-18, curved leading surface 114 has a constant radius of curvature.

The preceding subject matter of this paragraph characterizes example 56 of the present disclosure, wherein example 56 includes the subject matter of any of examples 52-55, above.

Changing angle α between apparatus 102 and surface 182 changes thickness 166 of layer 164 of viscous material 162 applied onto surface 182 by adjusting angle of outlet 108 of channel 104 relative to surface 182. More specifically, as angle α is decreased, angle of outlet 108 of channel 104 relative to surface 182 increases to increase thickness 166 of layer 164 of viscous material 162. In contrast, as angle α is increased, angle of outlet 108 of channel 104 relative to surface 182 decreases to decrease thickness 166 of layer 164 of viscous material 162.
