A cooling device disposed below the conveyor, wherein the cooling device is provided with a cool air supply passage through which cool air passes and is blown along the back surface of the substrate, and a heat blown along the back surface of the substrate from the cool air supply passage. An exhaust path for discharging the air after exchange to the outside is disposed so as to face horizontally with the conveyor interposed therebetween. (E) Function As will be described in detail in the embodiment, the transport conveyor (2)
The heating device (7) cures and / or solders the adhesive to which the electronic component (8) on the upper surface side of the printed circuit board (3) is attached while the printed circuit board (3) is transported downstream of the printed circuit board (3). At the same time, the cool air is blown from the cool air supply passage (10) to the back surface of the substrate to cool the lower surface of the substrate, and the air after the heat exchange is discharged to the adjacent exhaust passage (11). In addition, a printed circuit board (3) using a conveyor (2)
During the transfer movement to the downstream side, the adhesive to which the electronic component (8) on the upper surface side of the substrate (3) is attached is cured and / or soldered by the heating device (7). Simultaneously with the heating by the heating device, cool air is blown from the cool air supply path along the substrate (3) to cool the lower surface of the substrate. The air that has been heat-exchanged on the back surface of the substrate is discharged to an exhaust passage horizontally opposed to the cold air supply passage with the conveyor (2) interposed therebetween. (F) Example One example of the present invention will be described below in detail. (1) is a curing furnace main body, and a conveyor (2) is disposed in the main body (1).

The heating device (7) shown in this embodiment has various usage examples. For example, a far-infrared heater may be used instead of the near-infrared heater (7C), and the ultraviolet lamp unit (7A) may be used instead of the ultraviolet lamp unit (7A). Other infrared heaters may be used to form a reflow furnace, or an adhesive curing furnace that does not use a near-infrared heater (7C). (9) a cooling device disposed below a transport surface of a conveyor (2) for mounting and transporting the printed circuit board (3);
For cooling the back surface of the printed circuit board (3),
It comprises a plurality of cold air supply paths (10) and a plurality of exhaust paths (11). Note that it is also possible to simply blow cool air from the cool air supply passage (10). It is preferable that the cool air is cooled using a cooler, but only normal air may be used. This cooling device (9)
Will be described in detail below. First, (12) is a rectangular parallelepiped cooling box with an open top.
The cold air supply ducts (14) and the exhaust ducts (15) are alternately formed in a vertical direction by the plurality of partition plates (13).
An air supply pipe (17) connected to an air supply fan (16) that takes in outside air penetrates through the partition plate (13) and is branched to be distributed to the cool air supply duct (14). In addition, a diffusion lid (18) having a plurality of openings is provided above the cold air supply duct (14). on the other hand,
An exhaust pipe (20) connected to an exhaust fan (19) for exhausting the heat-exchanged air to the outside of the curing furnace main body (1) penetrates through the partition plate (13) and is branched into the exhaust duct (15). Its end is provided. Therefore, the cool air supply path (10) is formed by the air supply pipe (17) and the cool air supply duct (14), and the exhaust path (11) is formed by the exhaust pipe (20) and the exhaust duct (15). (21) is an air volume controller, which can be rotated 360 degrees with a support shaft provided in the middle as a fulcrum, and blows air volume or suction according to the rotation angle adjusted in the cold air supply duct (14) and the exhaust duct (15). The air volume is adjusted, and all of them may be linked or independently adjusted. In FIG. 1, the partition plate (13) is arranged in a direction perpendicular to the direction of transport of the printed circuit board (3), so that the exhaust duct (15) and the cold air supply duct ( 14) is provided alternately. However, the present invention is not limited to this, and as shown in FIG. 2, the partition plate (13) is disposed so as to be parallel to the transport direction of the substrate (3). From the depth side to the near side in the direction perpendicular to the transport direction,
5) and the cool air supply duct (14) may be arranged alternately. At this time, as shown in Fig. 3, the supply duct (14A)
And the ends of the exhaust duct (15A) are opposed to each other in the horizontal direction (however, a plurality of partition plates (13) are arranged side by side so as to be perpendicular to the transport direction), and the flow of the cool air is printed on the printed circuit board. The back surface of the printed circuit board (3) may be cooled in the horizontal direction along the back surface of (3). Further, as shown in FIG. 4, when a plurality of cold air supply ducts (14) and exhaust ducts (15) are alternately arranged in parallel (first
The embodiment shown in FIG. 2 and FIG. 2), a rectifying plate (22) may be provided at the top to facilitate recovery of air after heat exchange with the printed circuit board (3). The opening angle can also be adjustable. The operation of the above configuration will be described below.
First, the printed circuit board (3) is transferred onto the conveyor (2) by a conveyor (not shown) from the upstream of the curing furnace body (1), and is moved downstream by the conveyor (2). During this movement, the adhesive to which the electronic component (8) on the upper surface side of the printed board (3) is attached is cured and / or cured by the heating device (7).
Alternatively, soldering is performed. That is, the ultraviolet lamp unit (7A) and the far-infrared heater (7B) are sequentially arranged from the upstream side.
Cures the adhesive applied to the printed circuit board (3),
An ultraviolet lamp unit (7A), a far infrared heater (7B) and a near infrared heater (7C) preheat and melt the cream solder printed on the printed circuit board (3). At the same time, the back surface of the printed circuit board (3) on the conveyor (2) can be cooled by the cooling device (9). That is, outside air is introduced by the air supply fan (16), and cool air is blown to the back surface of the printed circuit board (3) through the air supply pipe (17) and the respective cool air supply ducts (14). It is not heated more than necessary, and the soldered electronic component (8) on the back side is not damaged by heat. The air that has been heated by heat exchange with the printed circuit board (3) and the electronic component (8) is heated by the exhaust fan (19) through the exhaust duct (15) and the exhaust pipe (20). It is discharged outside. At this time, the cool air is uniformly blown upward by the diffusion lid (18). However, if necessary, a rectifying plate (22) is provided so that the air after the heat exchange can be easily led to the exhaust duct (15). You can also. The air volume can be adjusted by the air volume controller (21). (G) Effects of the Invention As described above, according to the present invention, when the adhesive on the printed board is cured or soldered, wind can be blown to the back surface of the printed board, so that the printed board and the The electronic components on the back surface of the substrate can be prevented from rising in temperature, and the electronic components on the front surface of the substrate can be fixed with an adhesive or soldered without being damaged. Moreover,
When the adhesive on the printed circuit board is cured or soldered, wind can be blown to the back surface of the printed circuit board at a plurality of places, and the temperature rise on the back surface of the printed circuit board can be prevented over the whole. Further, the air blown to the lower surface of the substrate and subjected to heat exchange is discharged to the adjacent exhaust passage, so that it is possible to prevent the air from staying in the furnace and lowering the temperature in the furnace too much. Further, a cool air supply path and an exhaust path for discharging air after being blown along the back surface of the substrate from the cool air supply path and exchanging heat to the outside are disposed so as to face in a horizontal direction with the conveyor interposed therebetween. Therefore, it is possible to prevent the air blown out from the cold air supply passage from remaining in the furnace and excessively lowering the temperature in the furnace.
