Applying apparatus

1. An applying apparatus that applies a flux liquid, the applying apparatus comprising:

a housing that encloses a space;

a nozzle from which the flux liquid is injected, the nozzle located within the space; and

an intake and exhaust unit located within the space and enclosing an internal area that does not include the nozzle, the intake and exhaust unit having (i) an intake port through which a gas that includes the flux liquid that has been injected from the nozzle enters the internal area from the space and (ii) an exhaust port through which a as from which the flux liquid has been filtered exits the internal area, wherein

the intake and exhaust unit includes a filtering unit that filters the flux liquid from the gas that has entered the internal area through the intake port, the filtering unit being located between the intake port and the exhaust port in a gas flow path that extends through the internal area, and

the filtering unit is movably provided within the intake and exhaust unit so that when installing/removing the filtering unit with respect to the intake and exhaust unit, the filtering unit moves in a direction substantially parallel to a direction in which the gas that includes the flux liquid enters the internal area through the intake port and in which the gas that exits the internal area is exhausted through the exhaust port.

2. The applying apparatus according to claim 1 , wherein

the internal area of the intake and exhaust unit includes a first chamber through which the gas that includes the flux liquid reaches the filtering unit from the intake port, and a second chamber through which the gas from which the flux liquid has been filtered by the filtering unit reaches the exhaust port, and

a width of the first chamber in a direction orthogonal to the direction in which the filtering unit moves is smaller than a width of the second chamber in the direction orthogonal to the direction in which the filtering unit moves.

3. The applying apparatus according to claim 2 , wherein

the first chamber and the second chamber are formed by dividing the internal area of the intake and exhaust unit by an L-shaped compartment section, and

the compartment section includes (i) the filtering unit which extends substantially parallel to the direction in which the gas that includes the flux liquid enters the internal area through the intake port, and (ii) a dividing plate which extends in a direction orthogonal to the direction in which the gas that includes the flux liquid enters the internal area through the intake port.

4. The applying apparatus according to claim 1 , further comprising:

an exhaust pipe through which the gas that has passed through the filtering unit is exhausted externally from the applying apparatus, wherein

the exhaust pipe has an extension part extending into the intake and exhaust unit, and

a length of the extension part is smaller than an entire length of the filtering unit and larger than one-half the entire length of the filtering unit.

5. An applying system that applies a flux liquid, the applying system comprising:

the applying apparatus according to claim 1 ;

a first apparatus provided adjacent to a first side of the applying apparatus; and

a second apparatus provided adjacent to a second side of the applying apparatus, the first and second sides facing in opposite directions.

6. An applying method for applying a flux liquid, the applying method comprising the steps of:

(a) injecting the flux liquid from a nozzle that is located within a housing that encloses a space;

(b) sucking a gas that includes the flux liquid that has been injected from the nozzle into an internal area enclosed by an intake and exhaust unit through an intake port of the intake and exhaust unit, the intake and exhaust unit being located within the space of the housing, the nozzle being located outside of the internal area; and

(c) exhausting a gas from which the flux liquid has been filtered through an exhaust port of the intake and exhaust unit so that the gas from which the flux liquid has been filtered exits the internal area, wherein

the intake and exhaust unit includes a filtering unit that filters the flux liquid from the gas that has entered the internal area through the intake port, the filtering unit being located between the intake port and the exhaust port in a as flow path that extends through the internal area, and

the filtering unit is movably provided within the intake and exhaust unit so that when installing/removing the filtering unit with respect to the intake and exhaust unit, the filtering unit moves in a direction substantially parallel to a direction in which the gas that includes the flux liquid enters the internal area through the intake port and in which the gas that exits the internal area is exhausted through the exhaust port.

7. The applying method according to claim 6 , wherein

the internal area of the intake and exhaust unit includes a first chamber through which the gas that includes the flux liquid reaches the filtering unit from the intake port, and a second chamber through which the gas from which the flux liquid has been filtered by the filtering unit reaches the exhaust port, and

a width of the first chamber in a direction orthogonal to the direction in which the filtering unit moves is smaller than a width of the second chamber in the direction in which the filtering unit moves.

8. The applying method according to claim 7 , wherein

the first chamber and the second chamber are formed by dividing the internal area of the intake and exhaust unit by an L-shaped compartment section, and

the compartment section includes (i) the filtering unit which extends substantially parallel to the direction in which the gas that includes the flux liquid enters the internal area through the intake port, and (ii) a dividing plate which extends in a direction orthogonal to the direction in which the gas that includes the flux liquid enters the internal area through the intake port.

9. The applying method according to claim 6 , further comprising the step of:

(d) exhausting the gas that has passed through the filtering unit externally from the intake and exhaust unit through an exhaust pipe, wherein

the exhaust pipe has an extension part extending into the intake and exhaust unit, and

a length of the extension part is smaller than an entire length of the filtering unit and larger than one-half the entire length of the filtering unit.
