BACKGROUND OF THE INVENTION
The present invention relates to a tray for transporting an intermediate product or the like to a next process after a certain process is completed in a manufacturing site such as a factory.
[0002]
[Prior art]
When manufacturing a product in a factory, a transport tray is often used when an intermediate product or the like is transported to the next process after a certain process is completed. A wide variety of these transport trays are made and used in accordance with the types of products.
For example, when a reflective material is vapor-deposited on one surface of a small light guide plate used for illuminating a small liquid crystal display device, each light guide plate is transported to the work place of the vapor deposition step after the previous step. It is conveyed by.
[0003]
When transporting such a light guide plate, the upper surface and the lower surface that expand in a planar shape are places where fine processing has been performed, or of course, so of course it is not possible to randomly throw them into the transport tray and transfer one It is required to support and convey the sheet one by one, and it is necessary to support the upper and lower surfaces so as not to contact the conveyance tray.
Therefore, there is a problem that the light guide plate is moved only by being placed on each support chamber of the transport tray from above, and the light guide plate jumps out of the support chamber when an unexpected impact or the like occurs during the movement.
[0004]
[Problems to be solved by the invention]
In view of the above problems, an object of the present invention is to provide a transport tray that has high impact resistance and can support a transported object so that the transported object does not jump out even when an impact is encountered.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a top view of a transport tray 100 according to the present invention.
The transport tray 100 is manufactured from the same resin as the light guide plate 200 as a transported object, or from a resin that reuses the waste material of the light guide plate 200.
A slope 102 is formed on the upper side of the valley bottom 101 extending in the horizontal direction in the drawing, extends obliquely upward, and is connected to the continuous ridge 103 at the upper end. In addition, a slope 104 is continuously formed on the lower side of the valley bottom 101 in the drawing and extends obliquely upward, and the slope 104 is connected to the first divided ridge 105 at a portion where the slope 104 is highly extended, and a portion where the slope 104 is extended low. Then it is connected to the plain part 106. An edge in the horizontal direction in the drawing of the first divided ridge portion 105 is connected to the plain portion 106 via a slope 107, and a lower edge in the drawing is connected to the plain portion 106 via a slope 108.
[0013]
On the lower side of the first divided ridge portion 105 in the figure, a kidney-type lake portion 111 composed of a slope 109 and a lake bottom portion 110 extending downward from the plain portion 106 is formed.
A second divided ridge 112 is formed on the lower side of the lake 111 in the figure, and a slope 109 is extended and connected to the upper edge of the second divided ridge 112 in the figure. The lower side of 112 in the figure is connected to the continuous ridge 103 in the next row via the divided plateau 113. The lateral edges of the second divided ridge 112 and the divided plateau 113 in the figure are connected to the plain 106 by a slope 114. The plain 106 is connected to the next continuous ridge 103 via the slope 115.
[0014]
A plurality of three-dimensional features as described above are continuously formed on the tray 100.
A support chamber 116 that supports the light guide plate 200 is formed by the slopes 102, 107, 114, and 115. The slopes 107, 114, and 115 are two-stage slopes having a slope of about 45 degrees on the lower side and a slope that is nearly vertical on the upper side, and the light guide plate 200 is indicated by a one-dot chain line, In the figure of the outer periphery, the lateral and lower edges are placed on the boundary of these two-step slopes, and the upper edge is placed so as to hit the middle of the slope 102.
