2. Description of the Related Art An example of the prior art will be described with reference to FIG. As shown in FIG. 5, a conventional aging apparatus for electronic equipment includes an aging chamber 10, a rack 11 for mounting the electronic equipment, a hot air blower 14 for blowing hot air, a fan 13 for stirring room air, and a door for entering and exiting. 15. Then, a person carries the electronic device 20 in and out, and ages the electronic device 20.

Next, aging of electronic equipment will be described. Generally, aging is performed before shipment in order to equalize the quality of electronic devices and eliminate initial defects.

Aging is performed by keeping the aging chamber 10 at a constant temperature for a certain period of time while the electronic device 20 is energized. For example, the aging of the electronic device 20 is performed by setting the aging chamber 10 at a temperature of 50 ° C. ± 5 ° C. and energizing for 24 hours to 720 hours.

As described above, even when the temperature of the aging chamber 10 is constant, the aging time is desired to be changed for each product.
In addition, products may be carried out during aging for intermediate checking of products.

[0006] In the case of mass-produced products, an aging method in which the products are mounted on an automatic transfer device and continuously moved in a high-temperature bath is also performed, but is not suitable for aging in high-mix low-volume production. . In addition, the aging time cannot be set individually, and the equipment becomes large.

[0007]

As described above, a method for carrying out aging by transporting and moving electronic equipment by a person is as follows.
There was a practical inconvenience in that it was not possible to take in and out during nights and holidays when there were no people, and the aging time could not be set arbitrarily when using an automatic transport device.

Accordingly, the present invention has been made in view of these problems, and has as its object to keep the temperature of an aging chamber constant by a simple method, to automate the entry and exit of electronic devices, and to set the aging time individually. It is an object of the present invention to provide an aging device which can be set to the following.

[0009]

That is, a first aspect of the present invention, which has been made to achieve the above object, is a aging device for an electronic device, comprising: a controller for controlling a system;
A transport vehicle that automatically loads and unloads the electronic devices mounted on the pallet, a storage sensor that detects whether there is an electronic device to be loaded at the entrance, and whether there is an electronic device that has been released at the exit. An aging device characterized in that the aging device is characterized in that it comprises an outgoing sensor for detecting the temperature and an aging chamber in which the temperature is controlled by a hot air circulating means, and aging can be automatically performed for a time independently set for each electronic device. I have.

In order to achieve the above object, a second aspect of the present invention is to provide a buffer chamber for buffering the temperature between the aging chamber and the outside, an inlet of the buffer chamber and an inlet of the aging chamber. The aging device according to the first aspect of the present invention further includes a hanging curtain which can be opened and closed by movement of the carrier.
