Abstract

An adhesive applicator for applying adhesive to a lamination of a core of an electric motor has a first substrate having an adhesive flow passage for conveying adhesive and an air flow passage for conveying pressurized air, a second substrate having a second substrate passage, and a slider having a slider passage. The slider is between the first and second substrates and moves between first and second positions. In the first position, the slider passage receives adhesive from the adhesive flow passage. In the second position, pressurized air from the air flow passage propels adhesive out of the slider passage, into the second substrate passage, out of the second substrate passage, and onto the lamination of the core.

First claim

What is claimed is:

1. An adhesive applicator for applying adhesive to a lamination of a core of an electric motor, comprising:
a first substrate having an adhesive flow passage extending therein for conveying adhesive toward an adhesive flow passage outlet and an air flow passage extending therein for conveying pressurized air toward an air flow passage outlet;
a second substrate having a second substrate passage extending therein that includes a second substrate passage inlet, that is aligned with the air flow passage outlet and offset from the adhesive flow passage outlet, and a second substrate passage outlet; and
a slider having a slider passage that includes a slider passage inlet and a slider passage outlet, the slider being disposed between the first and second substrates and operable to move between a first position, wherein the slider passage inlet is aligned with the adhesive flow passage outlet such that the slider passage is configured to receive adhesive therein from the adhesive flow passage, and a second position, wherein the slider passage inlet is aligned with the air flow passage outlet and the slider passage outlet is aligned with the second substrate passage inlet such that the slider passage inlet is configured to receive pressurized air that is conveyed from the air flow passage through the air flow passage outlet to propel adhesive received within the slider passage out of the slider passage through the slider passage outlet, into the second substrate passage through second substrate passage inlet, out of the second substrate passage through the second substrate passage outlet, and onto the lamination of the core.

2. The adhesive applicator of claim 1 , further comprising:
a first outer seal that extends between the first substrate and the slider and that forms a ring about the adhesive flow passage outlet, the air flow passage outlet, and the slider passage inlet in the first and second positions of the slider;
a second outer seal that extends between the second substrate and the slider and that forms a ring about the second substrate passage inlet and the slider passage outlet in the first and second positions of the slider;
a first inner seal that extends between the first substrate and the slider and that forms a ring about the air flow passage outlet and the slider passage inlet in the second position of the slider, wherein the adhesive flow passage outlet is outside of the ring formed by the first inner seal, and the slider passage inlet is outside of the ring formed by the first inner seal in the first position of the slider; and
a second inner seal that extends between the second substrate and the slider and that forms a ring about the second substrate passage inlet and the slider passage outlet in the second position of the slider, wherein the slider passage outlet is outside of the ring formed by the second inner seal in the first position of the slider.

3. The adhesive applicator of claim 1 , wherein an air flow passage inlet of the air flow passage, the air flow passage outlet, the slider passage inlet, the slider passage outlet, the second substrate passage inlet, and the second substrate passage outlet are linearly aligned with each other in the second position of the slider.

4. The adhesive applicator of claim 1 , wherein the slider is configured to move between the first and second positions via translation.

5. The adhesive applicator of claim 1 , wherein a maximum width of the slider passage inlet is less than a maximum width of the air flow passage outlet and less than a maximum width of the adhesive flow passage outlet.

6. The adhesive applicator of claim 5 , wherein the maximum width of the slider passage inlet is substantially equal to a maximum width of the slider passage outlet, a maximum width of the second substrate passage inlet, and a maximum width of the second substrate passage outlet.

7. The adhesive applicator of claim 1 , wherein the adhesive flow passage is defined by the first substrate, the air flow passage is defined by the first substrate, the second substrate passage is defined by the second substrate, and the slider passage is defined by the slider.

8. The adhesive applicator of claim 1 , wherein the first substrate is a bottom substrate, the second substrate is a top substrate, and the slider is positioned vertically between the first and second substrates.

9. The adhesive applicator of claim 8 , wherein the slider is operable to move horizontally between the first and second positions, and wherein, in the second position, the slider passage and the second substrate passage are horizontally aligned, such that the second substrate passage is oriented to receive the adhesive that is propelled vertically upward from the slider passage via the pressurized air.

10. The adhesive applicator of claim 1 , wherein at least one of the first substrate and the second substrate is formed of plastic.

11. The adhesive applicator of claim 10 , wherein the slider is formed of metal.

12. The adhesive applicator of claim 11 , wherein at least a portion of the slider is coated with a diamond-like carbon coating.

13. A system for applying adhesive to a receiving substrate, comprising:
an adhesive dispenser for dispensing adhesive;
a pressurized air supplier;
an actuator; and
an adhesive applicator, comprising:
a first substrate having an adhesive flow passage extending therein and in fluid communication with the adhesive dispenser, such that the adhesive flow passage is configured to convey adhesive dispensed from the adhesive dispenser toward an adhesive flow passage outlet, the first substrate further having an air flow passage extending therein and in fluid communication with the pressurized air supplier, such that the air flow passage is configured to convey pressurized air supplied by the pressurized air supplier toward an air flow passage outlet;
a second substrate having a second substrate passage extending therein that includes a second substrate passage inlet, that is aligned with the air flow passage outlet and offset from the adhesive flow passage outlet, and a second substrate passage outlet; and
a slider having a slider passage that includes a slider passage inlet and a slider passage outlet, the slider being disposed between the first and second substrates and operably coupled with the actuator such that the slider is operable to move, via actuation of the actuator, between a first position, wherein the slider passage inlet is aligned with the adhesive flow passage outlet such that the slider passage is configured to receive adhesive therein from the adhesive flow passage, and a second position, wherein the slider passage inlet is aligned with the air flow passage outlet and the slider passage outlet is aligned with the second substrate passage inlet such that the slider passage inlet is configured to receive pressurized air that is conveyed from the air flow passage through the air flow passage outlet to propel adhesive received within the slider passage out of the slider passage through the slider passage outlet, into the second substrate passage through second substrate passage inlet, out of the second substrate passage through the second substrate passage outlet, and onto the receiving substrate.

14. The system of claim 13 , further comprising:
a first outer seal that extends between the first substrate and the slider and that forms a ring about the adhesive flow passage outlet, the air flow passage outlet, and the slider passage inlet in the first and second positions of the slider;
a second outer seal that extends between the second substrate and the slider and that forms
