Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a thermostatic chamber, and more specifically, it does not occupy an opening / closing space for a door and is capable of maintaining a constant temperature in the thermostatic chamber. Regarding a door for a tank.

[Prior Art] In a conventional constant temperature oven, a rigid door body is generally provided at the front opening of the constant temperature oven body so that it can be opened and closed, and the door body is rotated toward you to open and close the opening of the constant temperature oven body. It is supposed to do.

[Problems to be Solved by the Invention] However, since the door body of the conventional constant temperature oven rotates toward the front of the opening when opening and closing the door, a large space is required in front of the opening. Since a large space is required in front of the opening, the combination cannot be easily done especially when combined with an automatic loading / unloading device for automatically loading and unloading the test body in the constant temperature bath body. There's a problem.

The present invention has been made in view of the above problems, and an object thereof is to provide a thermostatic chamber in which the space in front of the opening of the thermostatic chamber main body is made small and which can be easily combined with an automatic loading / unloading device. To do.

[Means for Solving the Problem] The present invention for solving the above-mentioned problem is provided with a DU in a thermostatic chamber main body.
The entire surface of the heat-resistant flexible sheet, in order to allow the T-board to be inserted and removed, and to be wound sequentially when it is opened, or to be moved from the opening to the depth direction of the thermostatic chamber main body when opened. And a flexible door in which a plurality of long hollow ribs extending in a direction orthogonal to the moving direction are closely arranged on their longitudinal side surfaces.

[Operation] In the present invention, the flexible door closing the opening moves laterally along the opening to open the opening. The flexible door includes a flexible sheet and a plurality of elongated hollow ribs extending over the entire surface of the flexible sheet in a direction orthogonal to the moving direction of the flexible door and having side faces in the longitudinal direction closely arranged. Since it is equipped with and has flexibility, it is wound up or accommodated along the side surface of the constant temperature bath. Therefore, since this flexible door does not open toward the front of the opening, it does not require a space for opening and closing the opening, and can be easily combined with the automatic loading / unloading device. It also eliminates the need for a large space for the installation location.

On the other hand, since this flexible door has heat resistance and heat insulation, it does not lower the temperature in the thermostatic chamber body and does not deform or deteriorate due to the high heat in the thermostatic chamber.

[Embodiment] The present invention will be described in more detail with reference to an embodiment of the present invention.

FIG. 1 is a perspective view showing an embodiment of the present invention, and FIG.
FIG. 2 is a sectional view taken along the line II-II of the drawings, and in these drawings, 2
Is a box-shaped constant temperature bath main body, and 4 is a door that closes the opening 2a of the constant temperature bath main body 2.

The thermostat main body 2 is made of a fireproof heat insulating material, and a test body, for example, a DUT substrate on which a large number of ICs are mounted can be inserted and held inside.

As shown in FIG. 3, the door 4 is composed of a flexible sheet 4a and a plurality of ribs 4b continuously provided in the surface of the flexible sheet 4a in the axial direction. The heat insulating rib 4b has a substantially trapezoidal cross section and is hollow in order to enhance the heat insulating effect. As the flexible sheet 4a, it is preferable to use a heat resistant resin such as melamine or Teflon.

In front of the opening 2a of the constant temperature bath main body 2, as shown in FIG. 2, a pair of pulleys 12a, 12b, a belt 14 stretched between the pulleys 12a, 12b, and a pulley 12a were connected. A drive motor 16 is provided to form drive means for opening and closing the door 4. The leading portion 4A of the door 4 is connected to the belt 14 via a connecting member 18.

The connecting member 18 is movably attached to a guide rail provided on the upper front surface of the constant temperature bath main body 2 via a guide means such as a guide roller.

A traveling means such as a roller is attached to the lower end of the door 4, and the roller is guided by a guide having a U-shaped cross section.

Next, the opening / closing operation of the door of the constant temperature bath will be described.

First, the drive motor 16 causes the pulleys 12a and 12b to move toward the arrow a.
When the belt 14 is rotated in the direction of, the belt 14 is moved by the rotation of the pulleys 12a and 12b as shown by the arrow B.
The connecting member 18 also moves in the same direction as indicated by the arrow B, the door 4 is pulled by the connecting member 18 and moves in the direction indicated by the arrow B, and the opening 2a of the thermostatic chamber main body 2 opens. It becomes a state.

Further, the drive motor 16 causes the pulleys 12a and 12b to move in the direction of arrow b.
When the belt 14 is rotated in the direction of, the belt 14 is moved in the direction indicated by the arrow C by the rotation of the pulleys 12a and 12b.
The connecting member 18 also moves in the same direction as indicated by the arrow C, the door 4 is pulled by the connecting member 18 and moves in the direction indicated by the arrow C, and the opening 2a of the thermostatic chamber main body 2 closes. It becomes a state.

In the above embodiment, the door 4 is housed by sliding it along the side of the constant temperature bath main body 2, but as shown in FIG. Good.

Further, although the motor 16 is used as the driving means for opening and closing the door 4 in the above embodiment, it may be manually opened and closed.

Further, in the above embodiment, the heat insulating rib 4b has a hollow cylindrical shape, but a heat insulating material such as glass wool may be filled inside.

Further, a reflecting mirror may be provided on the back surface of the door 4, that is, the surface facing the inside of the constant temperature oven main body 2. By doing so, the heat insulating effect can be further enhanced.

ADVANTAGES OF THE INVENTION According to the present invention, the thermostatic chamber main body having an opening, the flexible sheet, and the entire surface of the flexible sheet extend in the direction orthogonal to the moving direction of the flexible door and in the longitudinal direction. Since it has a flexible door including a plurality of long hollow ribs whose side surfaces are closely arranged, it does not leak the heat in the constant temperature chamber despite the extremely simple structure. Since the temperature inside the constant temperature chamber can be kept constant, and the door does not deteriorate due to high heat inside the constant temperature chamber, and the opening and closing of the door can only be moved laterally, it is possible to open the door in front of the opening. It is possible to provide a constant temperature bath that requires less space to open and close than the doors of.
