BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a rack for accommodating plate materials according to the present invention.

FIG. 1 is a front view of a plate material storage rack according to the present invention, FIG. 2 is a right side view of FIG. 1, and FIG. 3 is an enlarged view of a main part of FIG. 4 is a cross-sectional view showing the bearing member, and FIG. 5 is a front view for explaining the use state of FIG.

The rack for storing plate materials is provided with a substantially boat-shaped metal base plate 1 having handles 2a and 2b at both ends in the longitudinal direction, and provided at both ends along the longitudinal direction of the base plate 1, and provided with shaft support holes at regular intervals. A pair of bearing members 3 having an end portion 6 supported by the bearing members 3;
A plurality of substrate receiving units 5 rotatably supported on the base plate 1 and arranged in parallel. The substrate receiving units 5 are formed in a frame shape by combining rod-shaped members 7 made of metal. In the vicinity of the end 6 of the substrate receiving unit 5 which is supported by the bearing members 3, 3, a rotation restricting portion 8 for restricting the rotation angle between the adjacent substrate receiving units 5 is provided. When the pivot 5 rotates by a predetermined angle, the rotation restricting portion 8 comes into contact with the adjacent rotation restricting portion and stops. Therefore, the substrate receiving unit 5 can maintain the inclination angles in two directions in a V-shape. Note that, as shown in FIG. 3, the board receiving units 5 located at both ends of the base plate 1 have the rotation restricting portions 8 abutting against the wall 9 of the base plate 1 and are restricted in rotation so that they can take a predetermined angle. Like that.

As described above, the adjacent substrate receiving units 5
A rotation restricting portion 8 for restricting the rotation angle between each other is provided,
When the substrate receiving unit 5 is stopped when rotated by a predetermined angle, when one substrate receiving unit 5 is to be rotated, the rotation restricting portions 8 with the substrate receiving unit 5 to be rotated come into contact with each other. All of the substrate receiving units 5 are rotated in conjunction with each other. For example, when the substrate receiving unit 5f is rotated toward the substrate receiving unit 5a, 5e, 5d, 5c,
b and 5a can be rotated in conjunction with each other.

The substrate receiving unit 5 is configured such that, when plate materials set on a plate material storage rack are supplied one by one onto a belt conveyor by an automatic supply device, a feed roller of the automatic supply device is disposed at an upper end of the substrate reception unit 5. The opening 10 is provided so as not to interfere with the contact.

As shown in FIGS. 3 and 4, a concave portion 12 for positioning the plate material to be housed is provided on the upper portion of the bearing member 3, and when the plate material is thin and easily bent, the end of the plate material is formed in the concave portion. 12 so that positioning can be performed.

When the base plate 1, the bearing member 3, and the substrate receiving unit 5 are used in a drying process,
It is desirable to use a metal in consideration of heat resistance, but if it is used upright, it may be made of a resin.

When the bar-shaped member 7 of the substrate receiving unit 5 is made of metal or has an edge portion, a coating layer (not shown) made of a Teflon tube or the like is provided, and a plate material such as a printed board to be stored is provided. It is desirable to prevent damage.

When a plate material is stored in the plate material storage rack of the embodiment of the present invention, the substrate receiving unit 5 shown by a solid line in FIG. 1 is rotated from the end (for example, from 5a) to the position of the imaginary line. Subsequently, as shown in FIG. 3, if a plate material such as a printed circuit board is inserted from above into a space between the board receiving units 5a and 5b opened in a V-shape, it comes into contact with other adjacently stored plate materials. It is possible to easily carry out the storing work without any trouble.

The present invention is not limited to the above embodiment. For example, in the above embodiment, the rotation restricting portion 8 is provided in the substrate receiving unit 5, but the notch is provided in the base plate 1 to rotate the notch. The restricting portion may be used, and another embodiment of the present invention will be described below. FIG. 6 is a front view showing another embodiment of the present invention, and FIG. 7 is a plan view of FIG. As shown in FIGS. 6 and 7, cutouts 15 are provided at predetermined intervals along the longitudinal direction of the base plate 1 according to the position of the bearing. The substrate receiving unit 5 has the notch 15
To restrict the rotation by contacting the end.

In the above embodiment, the substrate receiving unit 5 is formed into a frame shape by combining the rod-shaped members 7 in consideration of weight reduction and supply to the belt conveyor by using an automatic supply device. When the device is not used, or when there is no fear that components mounted on a printed circuit board or the like are abutted and damaged, a flat plate shape may be used.

[0021]

Since the present invention is configured as described above, the following effects can be obtained.

According to the first aspect of the present invention, even a thin flexing slab plate material can be stored between the substrate receiving units, and the substrate receiving unit is rotated and is regulated by the regulating portion of the adjacent substrate receiving unit. When the board is inserted between the board receiving units in order to store the board, the adjacent board receiving unit is rotated and opened in a V-shape, so that the board can be stored smoothly. Can be provided.

According to the second aspect of the present invention, it is possible to provide a plate material storage rack capable of protecting a substrate from being damaged by providing a coating layer on a rod-shaped member of a substrate receiving unit.
