Therefore, the carrier tray of the present invention can be applied to panels of various sizes. In addition, since the support portions are symmetrically distributed with respect to the center of the first surface, the two carrier trays are stacked without special attention to be alternately placed in the same direction or in the opposite direction, thereby avoiding the operator mistakenly stacking the carrier trays in the wrong direction. The result is that the panel stored inside the carrier tray is damaged to achieve the effect of preventing the stay.

The above described features and advantages of the present invention will be more apparent from the following description.

The invention provides a carrier tray suitable for carrying a panel. 1A is a schematic diagram of a carrier tray in accordance with an embodiment of the present invention. FIG. 1B is a cross-sectional view of the panel taken along line A-A of the carrier of FIG. 1A. Referring to FIG. 1A and FIG. 1B , the carrier 100 of the embodiment includes a carrier body 110 and a plurality of elastic members 120 . The carrier body 110 has a first surface 112. The carrier body 110 includes a bearing area 114 and a plurality of supporting portions 116 on the first surface 112.

In this embodiment, the carrying tray 100 is divided into two carrying areas 114. The manufacturer can divide the carrying tray 100 into a plurality of carrying areas 114, and the number and size of the carrying areas 114 are not limited by this embodiment. Each of the carrying areas 114 has a bearing bottom surface 114a and a plurality of fixing portions 114b on the bearing bottom surface 114a. As shown in FIG. 1B, the fixing portion 114b is swelled from the bearing bottom surface 114a for the elastic member 120 to be fitted.

The elastic member 120 may be a hollow gasket or a solid spacer having a slight elasticity to facilitate insertion or removal of the self-fixing portion 114b. In the present embodiment, the elastic member 120 is a commercially available circular gasket (O-ring). The circular gaskets on the market are available in a variety of gauge sizes. Since the elastic members 120 of the present embodiment directly use the finished products on the market, there is no need to separately mold and manufacture, which is more cost effective. The material of the elastic member 120 may be rubber or silicone rubber. Because the friction of the rubber is large, when the panel 10 contacts the elastic member 120, the panel 10 can be stably stayed in the bearing area 114. Further, in the clean room, the rubber does not have the problem of scratching the panel 10 due to dusting, but the material of the elastic member 120 is not limited thereto. In addition, the height of the elastic member 120 is greater than the height of the fixing portion 114b such that when the panel 10 is placed on the carrying portion 114, the elastic member 120 can contact the panel 10 to provide a frictional force to cause the panel 10 to stay in the carrying portion 114.

In this embodiment, the support portion 116, the fixing portion 114b and the carrier body 110 can be manufactured by compression molding, and the support portion 116 and the fixing portion 114b are integrally formed with the carrier body 110. The manufacturer can fabricate a suitable carrier tray 100 to carry panels of various sizes as desired. For example, the manufacturer can determine that the carrier tray 100 needs to have several load-bearing areas 114 and the size of each load-bearing area 114 in accordance with the conditions of the panel 10 that needs to be carried. Alternatively, the size, the number, and the position of the fixing portion 114b are determined according to the size, the number, and the position of the elastic member 120 required in the bearing portion 114, so that the elastic member 120 can be firmly fitted to the fixing portion 114b. . In addition, the carrier 100 of the present embodiment uses polystyrene as the material of the support portion 116, the fixing portion 114b and the carrier body 110 to fabricate the carrier 100 having higher hardness, better structural strength and light weight. Of course, the materials and manufacturing methods of the support portion 116, the fixing portion 114b, and the carrier body 110 are not limited thereto.

In this embodiment, the carrier tray 100 on which the panel 10 is mounted can be stored in the box in a stacked manner. FIG. 1C is a cross-sectional view of the carrier tray of FIG. 1A taken along line B-B. Please refer to FIG. 1C , which is a cross-sectional view of the support portion 116 of the carrier disk 100 . In the present embodiment, the carrier 100 is superposed on the other carrier 100 by the support portions 116. The support portion 116 of the present embodiment includes a cup-like structure having a cup portion 116a and a cup bottom portion 116b. The inner diameter of the cup mouth portion 116a is larger than the outer diameter of the cup bottom portion 116b such that the cup mouth portion 116a of the carrier tray 100 is adapted to receive the cup bottom portion 116b of the other carrier tray 100. Moreover, since the support portion 116 has a thickness, when the cup mouth portion 116a of the carrier tray 100 accommodates the cup bottom portion 116b of the other carrier tray 100, the cup bottom portion 116b of the other carrier tray 100 can be engaged without falling. The bottom portion 116b of the carrier 100 is such that the two stacked trays 100 have a spacing D. Moreover, when the two carrier disks 100 are stacked, the spacing D between the two carrier disks 100 may be greater than the thickness of the panel 10 to prevent the panel 10 from being crushed.

Referring back to FIG. 1A, the support portions 116 are symmetrically distributed with respect to the center of the first surface 112. Therefore, the operator does not need to pay special attention to placing the two carrying trays 100 in the same direction or in the reverse direction. Stay in effect. The support portion 116 may have a different shape. For example, in FIG. 1A, the cross-sectional area of the support portion 116 has both a circular shape and an elliptical shape. As long as the support portions 116 symmetrical to the center of the first surface 112 have the same shape, the two carrier disks 100 can be stacked in the forward or reverse direction. Of course, in other embodiments, the shape of the support portion 116 may be a triangular prism or other shape, and the shape of the support portion 116 is not limited to the above.

In addition, the carrier 100 of the present embodiment can be adapted to the panel 10 of each size. When the panel 10 is small, the elastic portion 120 can be selectively placed on the fixing portion 114b of the region to be used. The fixing portion 114b does not need to provide the elastic member 120 first to save cost. When the size of the panel 10 to be carried is close to the size of the load-bearing area 114, all the fixing portions 114b are attached to the elastic member 120. The carrier 100 of the present embodiment is in contact with the panel 10 through the elastic member 120 to provide friction. It is experimentally found that when the inclination angle of the carrier 100 is less than 75 degrees, the panel 10 can stay on the carrier 100 without slipping. In addition, since the panel 10 is not fixed to the carrier 100 by means of the snapping, the carrier panel 100 of the embodiment can be easily placed and removed to speed up the working time.

2A is a cross-sectional view of a carrier tray in accordance with another embodiment of the present invention. Referring to FIG. 2A, the main difference between the carrier 200 of FIG. 2A and the carrier 100 of FIG. 1B is that the fixing portion 214b of the carrier 200 of FIG. 2A is recessed on the bearing bottom surface 214a. The elastic member 220 can be fixed by being inserted into the fixing portion 214b recessed in the bearing bottom surface 214a. A portion of the elastic member 220 is still exposed to the bearing bottom surface 214a, and the panel can directly contact the portion of the elastic member 220 exposed on the bearing bottom surface 214a to provide friction to the panel 10.

2B is a schematic cross-sectional view of the support portion of the carrier tray of FIG. 2A. Referring to FIG. 2B, the support portion 216 is coupled to the first surface 212, and the support portion 216 includes a cup-like structure having a cup portion 216a and a cup bottom portion 216b. In the present embodiment, the cup mouth portion 216a is a tubular shape having the same inner diameter, and the inner diameter of the cup mouth portion 116a of Fig. 1C is gradually decreased along the axial direction of the cup bottom portion 116b. Of course, the shape of the cup mouth portion 216a is not limited thereto, as long as the cup bottom portion 216b of the other carrier tray 200 can be accommodated, and the spacing between the stacked two carrier trays 200 is greater than the thickness of the panel.

3A is a schematic diagram of a carrier tray in accordance with another embodiment of the present invention. Fig. 3B is a cross-sectional view showing the A'-A' of the carrier tray of Fig. 3A. Referring to FIG. 3A and FIG. 3B , the carrier 300 of FIG. 3 includes a carrier body 310 and a plurality of elastic members 320 . The carrier body 310 has a first surface 312. The carrier body 310 includes a bearing area 314 and a plurality of supporting portions 316 on the first surface 312. The carrying area 314 has a bearing bottom surface 314a and a plurality of fixing portions 314b on the bearing bottom surface 314a. The elastic member 320 is disposed on the fixing portion 314b and protrudes from the bearing bottom surface 314a. If the panel is placed in the load bearing area 314, the resilient member 320 will contact the panel to provide friction to cause the panel to rest in the load bearing area 314. In addition, the carrier trays 300 are superimposed on the other carrier trays 300 by the support portions 316 located around the first surface 312, and the support portions 316 are symmetrically distributed with respect to the center of the first surface 312.

The main difference between the carrier 300 of FIG. 3 and the carrier 100 of FIG. 1A is that the carrier 300 of FIG. 3 has only one carrying area 314, and the fixing portion 314b is evenly distributed on the carrying base 314a, so that the panel 10 can be placed on Any location on this load zone 314. Also, since there is no need to use a partial area to the first surface 112 to separate the two load-bearing areas 114 as shown in FIG. 1A. Therefore, the carrier 300 of the embodiment can be placed with more or larger panels, so that the carrier 300 is more flexible in application. Of course, the position and number of the carrying area are not limited thereto, as long as the elastic member of the carrying tray can provide friction and the panel stays in the carrying area.

In summary, the carrier tray of the present invention provides the panel friction force by the elastic member, and the panel stays on the carrier tray. Therefore, the carrier tray of the present invention can be applied to panels of various sizes. In addition, since the support portions are symmetrically distributed with respect to the center of the first surface, the two carrier trays are stacked without special attention to be alternately placed in the same direction or in the opposite direction, thereby avoiding the operator mistakenly stacking the carrier trays in the wrong direction. The result is that the panel stored inside the carrier tray is damaged to achieve the effect of preventing the stay.
