The present invention relates to a welding device for a fuel filter for filtering foreign substances contained in the fuel, and more particularly, to a fuel filter welding device for producing a fuel filter by melting the surface of the upper cap and the lower cap and then compressing the filter material. It is about.

In general, a fuel filter used in a vehicle is to supply clean fuel by filtering various foreign substances contained in the fuel, which is important in terms of improving fuel efficiency of the vehicle, reducing emission of pollutants, and preventing parts such as engine damage. Playing a role.

In particular, the fuel filter requires airtightness due to the filtering of foreign matter contained in the fuel, and also requires strength and durability that can be deformed or kept tight even in fluctuations and impacts caused by driving of the vehicle. Therefore, most fuel filters are bonded to each other by the filter medium, the upper cap and the lower cap.

Figure 1 is a perspective view showing a heat welder as an example of such a conventional fuel filter welding device, a clamp 11 for holding and fixing the filter medium as shown, and the upper and lower caps not shown by the LPG mixed gas It comprises a fireball (1) for heating and melting the surface of the, the fixing jig 20 for transferring the upper cap and the lower cap to the fireball (1) or clamp 11 side along the shaft (31).

Therefore, the conventional heat welder heat-melts the surface of the upper cap or the lower cap mounted on the fixing jig 20 by the flame port 1, and then inserts the upper cap and the lower cap whose surface is melted into the clamp 11. Pressurized with filter media.

However, such a conventional heat welder heat-melts the surface of the upper cap and the lower cap by flame using LPG mixed gas, so that the surface of the upper cap and the lower cap is burned or burned to melt the surface of the upper cap and the lower cap. Various problems have arisen such as curing. Therefore, there is a problem that the bonding between the upper cap and the lower cap and the filter medium is not made securely and airtight.

In addition, the conventional heat welder heats the surface of the upper cap and the lower cap without heat penetrating into the surface of the upper cap and the lower cap due to the nature of heating the upper cap and the lower cap by the flame (1). Therefore, since the filter medium is not deeply bonded to the upper cap and the lower cap, a solid bonding could not be made, resulting in a problem of poor airtightness and tightness of the fuel filter.

On the other hand, although not shown, there is a heat welder that uses a halogen lamp in addition to a flame lamp or heat-melts the upper cap and the lower cap by a cartridge heater. However, a heat welder employing a halogen lamp has excessive visible light due to the characteristics of the halogen lamp. On the other hand, the infrared emission is relatively weak, and the cartridge heater type heat welder has a long heating distance and a low heating amount, so that it is difficult to properly melt the surfaces of the upper cap and the lower cap.

In addition, since the heat generated from the halogen lamp is low in conductivity, the surface of the upper cap and the lower cap cannot be melted to a sufficient depth, thereby causing a fatal problem in that the filter medium and the upper cap and the lower cap cannot be firmly bonded.

The present invention has been made in order to solve the conventional problems as described above, the object of the present invention is to melt the surface of the upper cap and the lower cap without burning the fuel filter can be made of airtight and tightly welded with the filter medium It is to provide a welding device.

Another object of the present invention is to provide a welding device for a fuel filter that can improve the productivity according to the welding operation of the fuel filter because the melting and welding and discharge of the upper cap and the lower cap is made automatically.

The 1,2,3 clamping arms 521, 522, 523 are axially coupled to clamp the filter paper F3.

Referring to the operation and effect of the present invention configured as described in detail as follows.

As shown in FIGS. 4A to 4B and 6A, when the upper cap F1 and the lower cap F2 contact the upper and lower suction plates 341 and 391, the upper cap F1 is as shown in FIG. 3B. The lower cap F2 is stably sucked by the suction force of the suction hole 350 formed in the upper suction plate 341 and the lower suction plate 391.

In this state, when the filter medium F3 is inserted into both clamps 520 and the buttons of the operation unit 210 are operated, as shown in FIGS. 5A to 5D, the infrared lamp feeder 400 extends the length of the rear cylinder 480.
