In addition, when the panel base material collides with the container due to poor transport, the container may be damaged, or dust may be generated due to friction of the panel base material.

In view of the above-mentioned problems, the present invention aims to provide a reinforcing member capable of effectively protecting panels and panel transport containers, and a panel transport container using the reinforcing member. The side portion of the panel is connected to the circuit board via a flexible circuit.

solutions to problems

In order to solve the above-mentioned problems, the utility model provides a reinforcing member used in a panel transport container; the panel transport container is composed of a foamed molded product, and has a rectangular bottom and a side wall that stands up from the periphery of the bottom The storage area formed to accommodate one or more rectangular panels, so that the board surface of the panel is parallel to the horizontal direction; the reinforcing member is used to reinforce the storage area of the panel transport container The reinforcing member at the corner of the panel; the reinforcing member includes: an installation part, which is installed on the corner of the panel transport container; and a first protection part, when the installation part is installed on the panel transport container, along the panel The longitudinal side wall portion of the transport container extends vertically or slightly perpendicularly to the horizontal direction from the mounting portion so as to cover a part of the inner surface of the longitudinal side wall portion.

According to this structure, even if a load is applied to the corner of the storage area or from the corner of the panel due to an external impact due to accidental drop, the load will be dispersed by the reinforcing member. Foamed resin moldings are less prone to compression. Also, therefore, it is possible to ideally prevent impact from being applied to the panel, and to securely fix the panel without causing positional displacement in the storage area.

The above-mentioned reinforcing member can be selected from foamed resin material or non-foamed resin material, such as polystyrene resin, polyolefin resin, acrylic resin, polycarbonate and the like.

The first protecting portion may be a rod-shaped body or a plate-shaped body, and covers a part of the inner surface of the side wall constituting the corner portion of the panel transport container. Here, the mounting portion refers to a portion attached to the container, and the first protection portion refers to a portion abutting against a received panel. In addition, the attachment referred to here means fitting, locking, sticking, etc., and means attaching to the panel transport container.

In the above reinforcing member, a second protecting part is integrally formed with the first protecting part or is formed separately; It is installed vertically or slightly vertically so as to cover a part of the inner surface of the side wall portion in the short side direction.

According to this structure, since the reinforcing member has a cushioning effect in both orthogonal directions, it can have excellent impact resistance regardless of the impact from any direction.

In the above reinforcing member, the mounting portion is a columnar body mounted on a corner of the panel transport container along a depth direction of the panel transport container, and has a concave-convex shape in a horizontal cross section. The horizontal cross-section referred to here is a cross-section crossed by the mounting portion in the horizontal direction (direction parallel to the bottom) in the state mounted on the corner of the panel transport container. That is, the shape of the horizontal cross-section of the mounting portion may be not only a polygon such as a triangle or a square, an ellipse, or a circular column, but may also be a combination of the above shapes. Also, the mounting part can be hollow or solid.

According to this configuration, the attachment portion can be prevented from slipping due to frictional force by adopting a shape in which the reinforcing member and the side wall of the container are locked, or by increasing the contact area between the reinforcing member and the side wall of the container. Therefore, it can be fixed without using an adhesive, which can improve the workability of assembly and the stability of fixing.

In the above reinforcing member, a concave portion is formed at a position facing a corner portion of the stored panel along the plate thickness direction of the stored panel. In addition, the concave portion may be formed at a position facing the short side direction of the stored panel along the board thickness direction of the stored panel.

According to this configuration, it is possible to prevent the corners of the container from being directly impacted on the panel when the container is dropped, thereby preventing the corners of the panel from being damaged.

In the above-mentioned reinforcing member, a buffer sheet may be attached to a surface of the first protecting portion and/or the second protecting portion facing the panel to be housed. At this time, the buffer sheet is attached to a part or the whole of the surface of the first protection part and/or the second protection part facing the panel. The attachment method in the above case can be carried out by various methods such as adhesives and heat fusion.

The cushion sheet having flexibility serves as a cushion for the contact surface between the reinforcing member and the panel.

The above buffer sheet can be made of materials softer than the reinforcing member, such as silicone rubber, natural rubber, isoprene rubber, butadiene rubber, urethane rubber, styrene-butadiene rubber, nitrile rubber, Materials such as butyl rubber, ethylene-propylene rubber, fluorine-containing rubber, acrylic rubber, and polyolefin-based resins may be foamed or laminated.

In addition, the utility model provides a panel transport container, which is used to pack the packaged objects in which the circuit substrate is connected to the side of the rectangular panel via a flexible circuit; the panel transport container is formed to accommodate the A storage recess for the packaged object; a substrate storage recess for accommodating the circuit board of the packaged object is formed at the side edge of the storage recess; and at least at both ends of the side where the substrate storage recess is formed, there are formed The mounting portion is to detachably mount the reinforcing member at the corner of the panel that protects the object to be packed as described above.

The material of the above-mentioned panel conveyance container body is preferably a foamed molded article of thermoplastic resin. The above-mentioned thermoplastic resins can be used, for example: polystyrene resins, polyolefin resins (such as polypropylene resins, polyethylene resins), polyester resins (such as polyethylene terephthalate series, Polybutylene terephthalate-based resin, polyethylene naphthalene-based resin, polylactic acid-based resin), or a single resin such as polycarbonate-based resin or a composite of multiple resins. When the object to be bundled is a glass panel or an electronic component, it is better to use a foaming material that has undergone antistatic treatment.

The effect of utility model

As described above, according to the present invention, even if an external impact such as accidentally falling is received, the impact will be dispersed and buffered by the reinforcing member provided at the corner of the storage area, so ideally This impact is prevented from being applied to the panel base material, and the corners of the storage area are not deformed by receiving the load from the corners of the panel base material.

Detailed ways

Hereinafter, embodiments of the reinforcement member and the panel conveyance container of the present invention will be described with reference to the drawings. The panel transport container of this embodiment has the same structure as the conventional container with the storage space of the container body, but the difference lies in the reinforcing member and the mounting part of the container body. Therefore, the following description will mainly focus on the above differences.

Fig. 1 is a plan view of a rectangular panel 1 with a flexible circuit 1f accommodated in a panel transport container of the present invention. FIG. 2 is a partially enlarged view of the upper left corner of the top view of FIG. 1 . As shown in Figure 1, the purpose of the present utility model is to transport a rectangular panel 1 with a flexible circuit 1f, at the panel held parts a and c at the corners of the panel 1 in Figure 2, When there is little space (area) for holding the panel to withstand the impact during transportation, the panel 1 is held by the panel held portions a and c.

Moreover, the purpose of the present utility model is not only limited to preserving the panel 1 with the flexible circuit 1f, but also includes preventing dust, peeling, cracking, abrasion, etc. on the inner wall of the panel storage part of the panel container, and improving the durability of the container. .

As shown in FIG. 2 , at the panel held portions a and c, there is little enough holding width to protect the panel when impacted by transportation. Also, since the gap b is narrow and the flexible circuit 1f cannot touch the container, it is impossible to ensure that the container has a sufficient wall thickness for holding the panel.

Fig. 3a, Fig. 3b and Fig. 3c are respectively a top view, a front view (partial) and a sectional view of the front view after the conventional panel transport container 2 is placed into the panel 1. 4a and 4b are partial enlarged views of different aspects in the top left corner of the top view of FIG. 3a. The conventional panel transport container 2 has the following problems.

Problem 1, as shown in Figure 4a and Figure 4b, in general, in the case of such an existing panel form (the container of the foam body), although it is like the form A of Figure 4a, it should be kept as much as possible. The panel, however, cannot be achieved in terms of strength and shape, so it can only be in the form of aspect B as shown in Figure 4b. In the aspect B of Fig. 4b, the gap b is very narrow, and the flexible circuit 1f cannot touch the container 2, so it is difficult to form a deep flexible circuit 1f to protect its narrow gap as in the aspect A of Fig. 4a The shape of part d. Furthermore, since the thin wall of the foam container alone has insufficient strength, it is very difficult to form it into the shape of the part d.

Problem 2, as shown in Fig. 5a and Fig. 5b, Fig. 5a and Fig. 5b are partial enlarged views of different aspects in the upper left corner of the top view of Fig. 3a respectively. In Fig. 5a and Fig. 5b, on preventing the breakage of the corner portion of the panel 1, although it is general like the aspect C of Fig. Since the number of panel holding widths will further decrease, it is difficult to secure the corner portion c1 of the container unit of the foam in an avoidable shape, and it can only be formed like the form D in FIG. 5b.

Problem 3, as shown in Figure 6a and Figure 6b, Figure 6a and Figure 6b are partial enlarged explanatory diagrams in the upper left corner of the top view of Figure 3a respectively. In Fig. 6a, when the container 2 is subjected to an impact in the X direction or the Y direction, it is difficult to maintain the panel 1 due to insufficient width (receiving area) of the panel 1, resulting in a large displacement of the panel 1 in the impact direction, resulting in The panel contact portion of the container 2 is damaged, and the panel 1 is also easily damaged. In addition, in part p of FIG. 6 b , the panel 1 (especially the flexible circuit 1 f ) is likely to be damaged due to peeling, cracking, and twisting of the container 2 , or because the panel 1 intrudes into the container 2 .
