Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work drying device for removing a cleaning liquid adhering to a cleaned work such as a crystal oscillator or a ceramic thin plate for a capacitor from the work and drying the work.

[0002]

2. Description of the Related Art Conventionally, as a drying device for drying a work such as a crystal oscillator or an extremely small ceramic thin plate for a capacitor, which has been washed with a cleaning liquid such as water by a cleaning device,
For example, the one found in Japanese Patent Laid-Open No. 4-209515 is known. The drying device stores a plurality of works on a tray having a ventilable bottom plate, blows hot air from above the tray, and at the same time sucks hot air from below the tray to forcibly pass hot air into the gaps between the works. It is what makes me. At this time, the hot air blown onto the work is heated to a temperature at which the cleaning liquid can be evaporated.

According to such a drying device, the hot air blown from the hot air duct not only dries the moisture on the exposed surface of the work, but also when a plurality of works overlap each other, Hot air can enter the gaps to dry the water adhering to the gaps.

By the way, in the pre-process of the work of drying the work by this type of drying device, the work of washing the work is performed. In particular, if the work is an extremely small and lightweight work such as a crystal oscillator or a ceramic thin plate for capacitors, etc., and if such work is stored in a large number of trays and immersed in a cleaning liquid and cleaned by ultrasonic waves, When the tray is taken out from the cleaning liquid, a plurality of workpieces in the tray are stacked on each other to form a plurality of block-shaped work groups that are in close contact with each other via the cleaning liquid. The gap between the respective works forming these work groups is narrow, and the cleaning liquid firmly adheres thereto. On the other hand, the gap between the work groups is wider than the gap between the works, and in some cases, the gap may be large enough to communicate in the vertical direction of the tray.

When the work in such a state is dried by the drying device, the hot air blown from the hot air duct blows vertically between the work groups, which are relatively large gaps, between the work groups. The hot air cannot be uniformly blown to the works in the work group, and the heat of the hot air is difficult to be transferred. Therefore, there is a disadvantage that it takes a long time to completely dry all the works.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to provide a work drying device capable of efficiently and reliably drying a large number of plate-shaped works by solving the above disadvantages.

First, the tray 1 in which a large number of works W are stored is carried into the cleaning section 6 by the carry-in conveyor 9 of the carry-in section 2 shown in FIG. In the cleaning unit 6, the preliminary cleaning processing by the preliminary cleaning tank 3, the cleaning processing by the ultrasonic cleaning tank 4, and the rinsing processing by the ultrasonic rinsing tank 5 are sequentially performed on all the works W in the tray 1.

Then, as shown in FIG. 2, the cleaning of the respective works W by the cleaning unit 6 is completed, and the tanks 3, 4, of the cleaning unit 6 are finished.
The tray 1 storing a large number of works W to which water is attached in 5 is transferred to the elevating arm 19 of the drying unit 7. The elevating arm 19 hooks the hooking portion 33 formed at the lower end of the support arm 18 on the grip portion 15 of the tray 1, and then descends toward the inside of the drying tank 17 to support the tray 1 on the supporting portion 20. To do. At this time, the tray 1 is inclined and supported by the support portion 20 due to the inclination of the support frame 21, and accordingly, the support arm 18 of the elevating arm 19 releases the support of the tray 1. In this way, the tray 1 is inclined and supported by the support portion 20.

At the same time that the supporting arm 18 releases the support of the tray 1 by lowering the elevating arm 19, the hood 28 provided at the tip of the hot air duct 23 hits the upper portion of the side wall plate 14 of the inclined tray 1 by its own weight. It comes into contact.

As a result, the hot air duct 23 and the suction duct 24 are brought into communication with each other via the inside of the tray 1 supported therebetween. At this time, as described above, the tray 1
Since the bottom plate 13 of the tray is permeable and the side wall plate 14 is not permeable, each work W inside the tray 1 is in contact with only the hot air blown from the hot air duct 23 and is in a state of being shielded from the outside air. .

Next, the hot air is blown from the hot air duct 23, and at the same time, the hot air is forcibly sucked by the suction duct 24.
