Description

The present invention relates to a far-infrared heating blow-out panel with a built-in heater used for uniformly heating a product to be heated in a heating furnace.

As shown in FIG. 8, conventionally, when heating a product P, a heater 2 is installed inside the furnace 5 to heat the internal air and circulates inside the furnace 5 with a fan 7 to eject a plurality of hot air. Hot air is injected from the hot air injection panel 1 having the holes 6 to heat the product.

In the conventional heating furnace, the air heated by the heater 2 is blown out from the panel 1 and hot air is blown out from the panel 1 to heat the product. A large amount of electric power and nitrogen gas in the furnace is consumed to intensify the hot air that is injected for uniform heating. Unless the wind speed is strong, uniform heating is not possible, so the product is easy to dry, and the solvent for soldering is dried quickly, resulting in poor product finish. In addition, the parts position of the product is moved by strong wind, the board body is also moved, and the product defect is more likely to occur. Increases product rejection rate and causes large monetary losses in production.

The present invention is a far-infrared heating jet panel with a built-in heater that integrates a heater for heating a product in a heating furnace and a hot air jet panel, and the heat generation temperature distribution on the hot air jet panel surface can be mechanically controlled. A heater, two insulating materials arranged vertically above and below the heater, and two hot air blow-out panels arranged vertically above and below the two insulating materials and having a surface applied with a far-infrared effect agent Wherein the heater, the insulating plate, and the hot air ejection panel are provided with a plurality of ejection holes so as to penetrate the heater, the insulating plate, and the hot air ejection panel.

The heating conditions for the product have been improved due to the integration of the heater and the hot-air blow-out panel. However, the heating position and the capacity of the heater in the panel can be changed for uniform heating, so the hot-air blow-out panel surface is made uniform. Heating can be performed, reducing nitrogen gas, electric power and preventing the thirst of flux of component shift of the product.

In the reflow furnace heating, a far-infrared heating jet panel with a built-in heater that has a structure capable of mechanically adjusting the heat generation distribution of the heater is installed to uniformly heat the product using far infrared rays and weak warm air together. Perform heating.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Figure 1 shows the heating structure of the present invention. Insulating material 3 above and below heater 2 Heating far-infrared heating jet panel with built-in heater arranged above and below by hot air jet panel 1 and jetting out of hot-air jet hole 6 with built-in heater by stirring fan 7 The hot air 4 is blown out to heat the product P.

FIG. 2 is a detailed view of the heater of the present invention. The heater 2 has an insulating material 3 above and below, and a hot air blow-out panel 1 above and below the insulating material 3 and has a built-in far-infrared heating blow-out panel structure.

FIG. 3 shows a structure in which a uniform heater wire 10 is arranged on a heater member 9.

FIG. 4 shows a heating temperature distribution in a case where the completed heater of FIG. The far-infrared heating force 8 at the center of the hot-air blow-out panel 1 is smaller than at both ends, so that average heating cannot be performed.

Fig. 5 shows the heater structure incorporated in the panel proposed this time. The heater 2 is incorporated in the hot air blow-out panel 1 instead of being installed at regular intervals in the heater member 9, and is energized to measure the temperature of the surface of the hot air blow-out panel 1 so that the center of the hot air blow-out panel 1 is uniformly heated. By arranging the heater wires 13 densely arranged at both ends with the heater wires 14 arranged sparsely, the heat generation temperature of the hot air blow-out panel can be made uniform.

Fig. 6 shows the heater structure incorporated in the panel proposed this time. Instead of being wrapped around the heater member 9 at regular intervals, the heater 2 is incorporated into the hot-air blow-out panel 1 and energized to measure the temperature of the hot-air blow-out panel 1 so that the heat generated by the hot-air blow-out panel 1 is uniform. This is a structure of a capacity mixing heater 12 manufactured by using a capacity mixing heater wire 11 in which heater wires are arranged and heater wires having different capacities are welded and mounted in the middle of the heater wires in order to make heat generation more uniform.

FIG. 7 illustrates a situation in which the capacity mixing heater 12 of FIGS. 5 and 6 is incorporated in the hot air blow-out panel 1. By applying a far-infrared effect agent to the surface of the hot air blow-out panel 1, a strong heating effect by far infrared rays can be obtained. The heating power 8 of far-infrared light is made uniform by the heat generated by the capacity mixing heater 12 according to FIGS. 5 and 6, so that the heating of the product becomes uniform and the product can be uniformly heated.
