Description

Fuel pipe application device for automobiles {a application device of fuel pipe of automobile}

The present specification relates to an applicator, and more specifically, to apply an adhesive such as epoxy to a fuel pipe for fuel inlet and outlet mounted on the head of a fuel filter for filtering foreign substances contained in fuel. It relates to a fuel pipe metering device.

Generally, the fuel filter of a vehicle removes various impurities contained in the fuel before the fuel enters the engine, and only the pure fuel from which the impurities are removed can be supplied to the engine. The failure can be prevented in advance.

In other words, impurities or moisture contained in the fuel supplied to the engine adversely affects various mechanisms in the engine fuel system. In particular, a small amount of water may be present in the fuel stored in the fuel storage place (fuel tank, etc.), or a small amount of water vapor present in the air may condense and mix with the fuel.

If moisture is contained in the fuel, it does not play a lubricating role, causing scratches on precision machinery such as high-pressure pumps or nozzles of the fuel system, or deteriorating the sealability by corrosion of the machinery.

As a result, not only the high pressure can be compressed but also the fuel cannot be injected at the high pressure from the nozzle. Therefore, when the combustion occurs, soot or power is reduced, fuel consumption may be relatively increased.

Hereinafter, with reference to the accompanying drawings will be described in detail the fuel pipe meter coating apparatus for a vehicle according to a preferred embodiment of the present specification.

1 to 5, the fuel pipe metering coating device for an automobile according to an embodiment of the present disclosure

A frame 11 on which the control unit 10 (including, for example, a power on / off switch, a display window, a manual / automatic display unit, an adhesive liquid temperature display unit, etc.) is mounted;

Mounted on one side of the frame 11, the flange 12 is formed on the upper edge that is opened, when heated to the heating chamber holding the adhesive liquid (refer to the temperature (about 100 ~ 120 ℃)) is heated to chemical reaction And a container 13 filled with an adhesive which acts as a loctite to fix the fuel pipe 22 coupled to the fastening hole of the head portion 28 of the fuel filter (not shown). A cylindrical hopper 14 accommodated and formed of a transparent body or a translucent body so that the user can visually see the inside;

Air is injected into the hopper 14 by an air inlet 15 which is seated on the flange 12 of the hopper 14 to close the opening of the hopper 14 and is connected to an air supply source (not shown). Accordingly, a disc-shaped lid 17 in which a port 16 for discharging the adhesive liquid from the container 13 is formed on the upper surface thereof;

Ring-shaped clamp 18 (removably fastened by fastener 31) by surrounding the edges of flange 12 and lid 17 of hopper 14 to seal inside of hopper 14 (work For example, it is divided into three pivotally hinged members, but may be divided into two hinged members, ie a ring-shaped clamp 18 according to the diameter of the flange 12 and the lid 17. The number of uses can be selected and used);

It is mounted on the other side of the frame 11 by a cylinder 19 so as to be lifted and lowered, and is fixed to a port 16 formed on the upper surface of the lid 17 when air pressure is injected into the hopper 14, and the suction port is inside the container 13. A nozzle 21 for discharging the adhesive liquid discharged from the container 13 through the hose 20 positioned at the;

A metal material (for example, stainless steel material) may be used that is rotatably connected to a drive motor (not shown) mounted on the frame 11 and in which an adhesive liquid discharged from the nozzle 21 is applied to the outer circumference thereof. And a spindle 23 to which the fuel pipe 22 is detachably fixed.

According to a more preferred embodiment at this time, it is further provided with a magnetic material (not shown) formed in the spindle 23, for detachably fixing one end of the fuel pipe 22 fitted to the spindle 23.

Filled at arbitrary levels inside the hopper 14 to the outside of the container 13, and maintained at an arbitrary temperature (for example, about 40 to 50 ℃) to prevent the adhesive liquid filled in the container 13 to harden In addition, the hot water 24 for the heater for mutually heat-exchanging the adhesive liquid by the indirect heating method is further provided.

Therefore, the adhesive liquid in the container 13 can maintain a set viscosity by simply heat-exchanging the adhesive liquid of the container 13 by the hot water for heater 24 filled and circulated in the hopper 14.

Therefore, when a separate heating device is provided to supply a heat source from the outside of the hopper 14 to the inside of the hopper 14 so as to exchange heat with the adhesive liquid of the container 13 to maintain the set viscosity, the structure is complicated. The increase in the number of parts may cause a problem of an increase in cost.

The inner surface of the hopper 14 is formed to protrude from the hopper 14 so that the inlet and the outlet communicate with each other, and the hot water 24 for the heater inside the hopper 14 can be visually checked to maintain whether the water level is maintained. It further comprises a gauge for checking the water level (26) formed of the tube (25).

For this reason, the water level of the hot water 24 for heaters inside the hopper 14 can be visually confirmed through the tube 25 of the water level confirmation gauge 26. That is, when a part of the hot water for heater 24 is extinguished due to mutual heat exchange with the adhesive liquid in the container 13 or naturally evaporated in the hopper 14 to reduce the amount of hot water, the adhesive liquid in the container 13 and the hot water for heater 24 ) Mutual heat exchange cannot be performed smoothly.

Therefore, the hot water 24 for the heater may be replenished by the set amount in the hopper 14 through a hose circulated outside the hopper 14 so that the hot water for the heater 24 maintains the set temperature.

Opening / closing of the on / off valve 30 connected to the nozzle 21 so that the adhesive liquid discharged through the nozzle 21 is discharged to the fuel pipe 22 that is detachably fixed to the spindle 23 and is rotated. It is further provided with a timer (not shown) for controlling.

As a result, the amount of adhesive liquid applied to the fuel pipe 22 through the nozzle 21 is kept constant and uniformly applied, thereby improving the quality (when the fuel is conventionally experienced by the operator. Since the amount of the adhesive liquid applied to the pipe 22 is determined, the adhesive liquid is unevenly applied to the fuel pipe 22 to generate a defective product.

In the drawing, reference numeral 27 denotes a temperature sensor for sensing a temperature of the hot water for heater 24 filled in the hopper 14 and inputting the measured temperature value to the controller 10, and 29 denotes an opening of the spindle 23. A guide pin for supporting the fuel pipe 22 so as to protrude and to detachably couple the fuel pipe 22 to the spindle 23, and 32 is an air pressure exceeding a set pressure inside the hopper 14. It is an air vent to discharge to the outside when it occurs.

Hereinafter, an example of use of the fuel pipe metering coating device for an automobile according to an embodiment of the present specification will be described according to the accompanying drawings.

1 to 5, the container 13 filled with any adhesive liquid (e.g., an adhesive such as a two-part epoxy) is replaceably housed inside the hopper 14, but the hopper 14 The hot water 24 for the heater circulated so that the arbitrary temperature can be maintained therein is filled to the level of the container 13 so as not to overflow.

In order to discharge the adhesive liquid of the container 13 to the outside of the hopper 14, the inlet port is fixed to the port 16 formed on the upper surface of the lid 17, the middle side of the hose 20 located inside the container 13, The outlet of the hose 20 is connected to communicate with the on / off valve 30 for turning on / off the pipe of the nozzle 21 for discharging the adhesive liquid to the fuel pipe 22.

The disc-shaped lid 17 is seated on the flange 12 of the hopper 14 so as to close the opening of the hopper 14, and wraps around the edge of the flange 12 and the lid 17 of the hopper 14. By fastening the ring-shaped clamp 18 by the fastener 31, the inside of the hopper 14 can be sealed.

At this time, the fastener 31 is connected to the hinge pin 31a and the hinge pin 31a which are formed on the first protrusion 18a extending on one side of the clamp 18 so as to be rotatable, and the screw portion is formed on the outer circumference. The bolt-shaped body 31b to be formed and the other end of the body 31b is screwed on, and is supported on the second protrusion 18b extended to the other side of the clamp 18 so as to face the first protrusion 18a and sliding. The anti-slip for prevention is provided with the handle 31c formed in the surface.

Therefore, as the air pressure is injected into the hopper 14 at an arbitrary pressure from the air supply source through the air inlet 15 formed on the upper surface of the lid 17, the container 13 replaceably housed in the hopper 14 is provided. The filled adhesive liquid may be discharged to the outside of the hopper 14 along the hose 20 in which the suction port is located inside the container 13.

At this time, as the air pressure is injected into the hopper 14 sealed by the lid 17 mounted in the opening, the adhesive liquid is discharged through the hose 20 from the container 13 accommodated inside the hopper 14. Are technical details used in the art to which this specification belongs, and their detailed descriptions will be omitted.

After being discharged from the container 13 through the hose 20, the adhesive liquid applied to the outer surface of the fuel pipe 22 through the nozzle 21 is applied to the on / off valve 30 installed at the outlet of the hose 20. The adhesive liquid is interrupted by this.

At this time, the fuel pipe 22 is coupled to the spindle 23 rotated by a drive motor (not shown). That is, when one end of the fuel pipe 22 formed of a metal material is inserted into the spindle-shaped pipe 23, the fuel pipe 22 is detachably attached to a magnetic material (not shown) formed in the spindle 23.

Thus, the fuel pipe 22 coupled to the spindle 23 is rotated at an arbitrary speed by the drive motor.

As described above, the magnetic material formed inside the spindle 23 is used to detachably fix the fuel pipe 22 to the spindle 23 so as to detachably fix the fuel pipe 22 to the spindle 23. The number of parts can be reduced. In addition, it is possible to improve work efficiency by reducing the work time for attaching and detaching the fuel pipe 22 to the spindle 23.

As shown in FIG. 3B, the on / off valve 30 and the nozzle 21 connected to the on / off valve are connected to the fuel pipe 22 by the lifting body 19a linearly moving as the cylinder 19 is extended and driven. ) Can be lowered at the same time.

Therefore, the fuel pipe 22 rotates the adhesive liquid discharged from the hopper 14 through the hose 20 from the container 13 and then discharged through the nozzle 21 via the on / off valve 30. It can be applied to the outer surface of the.

At this time, the amount of adhesive liquid discharged through the nozzle 21 and applied to the outer surface of the fuel pipe 22 may be controlled by a timer controlling the opening / closing time of the on / off valve 30.

On the other hand, after filling the inside of the hopper 14 to the outside of the container 13 at an arbitrary level, the adhesive liquid filled in the container 13 by the hot water 24 for the heater circulated to maintain the arbitrary temperature can be prevented from hardening. have.

That is, when the temperature of the hot water for heater 24 filled in the hopper 14 detected by the temperature sensor 27 installed inside the hopper 14 is 40 ° C. or less, the hot water for heater 24 of the hopper 14 and Since the mutual heat exchange effect of the adhesive of the container 13 is not performed smoothly, the viscosity of the adhesive liquid of the container 13 becomes low. This prevents the adhesive liquid from being smoothly discharged along the hose 20 from the container 13 of the hopper 14.

On the other hand, when the temperature of the hot water for heater 24 filled in the hopper 14 sensed by the temperature sensor 27 is 50 ° C or more, the hot water 24 for the heater of the hopper 14 and the container 13 Since the mutual heat exchange action of the adhesive is excessive, the viscosity of the adhesive liquid of the container 13 becomes high. Therefore, when the adhesive liquid is discharged to the outer surface of the fuel pipe 22 through the nozzle 21, it flows down from the fuel pipe 22.

On the other hand, when the adhesive liquid filled in the container 13 is consumed, the clamp state of the clamp 18 is released by loosening the fastener 31, and then the lid 17 is removed from the hopper 14. The container 13 can be replaced inside the hopper 14.

As shown in FIG. 5, the head portion 28 of the fuel filter (not shown) on which the fuel pipe 22 is mounted is mounted on the fuel filter cartridge, and receives fuel from the fuel tank to supply fuel to the fuel filter cartridge. And it is used to receive the filtered fuel from the fuel filter cartridge to supply to the engine.

On the other hand, the fuel pipe 22 refers to a suction pipe mounted on the fuel inlet of the head portion 28 and a return pipe mounted on the fuel outlet.

The above-described fuel inlet and outlet fuel pipe 22 and the head portion 28 on which the fuel pipe 22 is mounted are used in the technical field to which the present disclosure belongs, and thus, detailed descriptions thereof will be omitted.
