DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drying apparatus for drying or reacting a product by heating.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 2 (a) and 2 (b), when a large number of electronic parts 102 such as ferrite are coated with a resin and both surfaces thereof are to be reacted, a motor 103 is used to rotate the rotating plate 10 and the like.
5 was rotated once while being heated by the heating device 104 to react the resin on one side, and then the electronic component 102 was turned over and rotated once with the other side up to react. Rotating plate 1
05 was cooled by the cold water of the cooling device 106.

[0003]

Accordingly, there has been a problem that a long time is required for a drying operation (reaction) and a long time is required for drying a large number of electronic components.

[0004] Therefore, an object of the present invention is to reduce the time of the drying operation.

[0005]

SUMMARY OF THE INVENTION In view of the above problems, the invention according to claim 1 includes a conveyor for transporting a workpiece, a heating device for heating the workpiece transported by the conveyor, A cylinder erected at an outlet of the conveyor, a water tank provided at a lower part of the cylinder, and a hot air supply device for supplying hot air downward from an upper part of the cylinder or upward from a lower part of the cylinder. It is a drying apparatus characterized by the following. This allows
The workpiece can be dried (reacted) in a short time, and the above problem can be suitably solved.

Here, the hot air supply device includes various heating devices such as a heater and a hot air device. The workpiece is typically an electronic component (e.g., ferrite), which is extremely convenient for performing a large amount of drying work in a short time.

According to a second aspect of the present invention, a workpiece is coated with a resin, and the workpiece is heated until a temperature close to, but lower than, the reaction temperature of the resin is reached. The drying device according to claim 1, wherein the device is heated. Thus, by bringing the temperature close to the reaction temperature in advance, the reaction can be completed in a short time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A drying apparatus 1 according to an embodiment of the present invention will be described below with reference to FIG. This drying device 1
Is a conveyor 3 for transporting electronic parts 2 made of ferrite.
And a heating device 4 provided above the conveyor 3 and provided with a heater for heating the electronic components 2 conveyed by the conveyor 3
And a tube 5 erected near the outlet of the conveyor 3 and capable of allowing the electronic component 2 to naturally fall and react, a water tank 6 provided at the lower portion of the tube 5 for storing room-temperature water, and connected to the lower portion of the tube 5 Hot air supply device 8 provided with a pipe 7 for supplying hot air upward
And characterized in that: Here, an exhaust port is provided in the upper part of the cylinder 5 so that the hot air supplied from the pipe 7 can be discharged. here,
The reaction is for accelerating the curing of the resin material containing the curing agent and the main agent. Epoxy resins, polyester resins, etc. are targeted. Thermosetting resin is a chemical reaction, and thermoplasticity is a melting reaction in the case of resin coating. It is also suitable for baking, tempering, and humidity control after plating.

<Operation of Drying Apparatus 1> Before entering the drying apparatus 1, a work is applied to the electronic component 2 in a pre-process by applying a resin. The heating device 4 heats the electronic component 2 until the temperature rises to a temperature close to the reaction temperature of the resin but lower than the reaction temperature.
Specifically, preheating is performed at a temperature before the reaction (145 degrees when the reaction temperature is 150 degrees) to shorten the reaction time.
The electronic components 2 discharged from the conveyor 3 fall in the internal space of the cylinder 5, and the hot air heated by the hot air supply device 8 blows up from below, and the hot air heats the electronic components to react and dry the surface. Let it. The inside of the natural fall tube 5 is hot air of about 300 degrees, and the temperature of the electronic component 2 is from 145 degrees to 40 degrees.
About 185 degrees at the outlet of the cylinder 5, and then falls into the water tank 6 and is cooled by room temperature water.

<Effects of Drying Apparatus 1> The drying apparatus 1 reacts and dries the electronic components 2 while they fall naturally, so that the time required for the drying operation can be reduced as compared with the conventional example shown in FIG.

It should be noted that the present invention is not limited to the above-described embodiments or examples, but may be modified without departing from the technical idea of the present invention. Such changes are also included in the technical scope of the present invention. The workpiece can be applied either hollow or solid. For example, hot air may be blown down from above.

[0012]

According to the first and second aspects of the present invention,
The drying operation time of the drying device can be reduced.
