TRAY FOR STORING AND TRANSPORTING WORKPIECES
A group of trays is configured for storing and transporting workpieces. Each tray includes a base and a frame. The base includes a plurality of receiving portion for receiving the workpieces. The frame surrounds the base to form a cavity. A plurality of projections are formed at the outer side of the flange. When two trays are stacked whether in a same direction or opposite direction, the lower tray is partially received in the cavity of the upper tray, and the projections of the lower tray resist the frame of the upper tray to stop the lower tray from being further inserted into the cavity of the upper tray.

1. Technical Field
The present disclosure relates to trays, particularly, a tray used to store and transport elements of portable electronic device.
2. Description of Related Art
Elements of portable electronic device, such as battery covers, printed circuit boards and so on, go through many processing steps during their manufacturer. These elements are generally transported with trays. The trays have numerous form fitting compartments so that numerous elements can be handled and transported at one time. Generally, the trays have a same structure and can be stacked one by one to save space. When the elements are put into the trays, the trays need to be detached from each other. However, it can be hard to detach one tray from the others.
Therefore, there is room for improvement within the art.
Many aspects of the tray can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the tray, in which:
Also referring to
There are two ways to stack the trays 100 . One way is that the corresponding blocks 137, 139 of two trays 100 are aligned with each other. This way is shown in
Another way to stack the trays is that, the upper tray 100 is rotated 180 degrees relative to the lower tray 100, and the grooves 133, 134 of the upper tray 100 are not aligned with the corresponding blocks 137, 139 of the lower tray 100. This method is shown in
It is to be further understood that even though numerous characteristics and advantages of the present embodiments have been set forth in the foregoing description, together with details of the structures and functions of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
Claims
1. A group of trays for storing and transporting workpieces, each tray comprising:
- a base including a plurality of receiving portions for receiving the workpieces; and
- a flange, the flange surrounding the base to form a cavity, the flange including a top surface; a plurality of projections formed at the outer side of the top surface; when then trays are stacked in a same direction or an opposite direction, the base of the lower tray is received in the cavity of the upper tray, and the projections of the lower tray resist the top surfaces of the upper tray to prevent the lower tray from being further inserted into the cavity of the upper tray.
2. The group of trays as claimed in claim 1, wherein a plurality of blocks are formed at an outer side of the flange of each tray, and when the trays are stacked in opposite directions, the blocks of the lower tray resist the top surfaces of the upper tray.
3. The group of trays as claimed in claim 2, wherein the trays are made of a plastic.
4. The group of trays as claimed in claim 3, wherein the trays are formed by suction molding.
5. The group of trays as claimed in claim 4, wherein the flange of each tray is partially recessed at an inner side to define a plurality of grooves corresponding to the blocks respectively, the grooves communicating with the top surfaces, and the projections of the upper tray prevent the blocks of the upper tray from being further inserted into the corresponding grooves of the lower tray when two trays are stacked in a same direction.
6. The group of trays as claimed in claim 5, wherein the blocks of each tray are positioned at different locations.
7. The group of trays as claimed in claim 6, wherein the grooves comprise side grooves and corner grooves, and accordingly the blocks comprise side blocks and corner blocks.
8. The group of trays as claimed in claim 1, wherein the projections are tapered and a width of the projection decreases with increasing distance from the top surface of the flange.
9. A group of trays for storing and transporting workpieces, each tray comprising a base and a flange, the flange and the base defining a cavity; the base including a plurality of receiving portions for receiving the workpieces; a plurality of projections and blocks being formed at the outer side of the flange; when the trays are stacked in a same direction or an opposite direction, the base of the upper tray is received in the cavity of the lower tray; when the trays stacked in an opposite direction, the blocks of the upper tray resist the flange of the lower tray to prevent the upper tray from being further inserted into the cavity; when the trays are stacked in a same direction, the projections of the upper tray resist the flange of the lower tray to prevent the blocks of the lower tray from being inserted into the cavity of the lower tray.
10. The group of trays as claimed in claim 9, wherein the trays are made of plastic material.
11. The group of trays as claimed in claim 10, wherein the trays is formed by suction molding.
12. The group of trays as claimed in claim 9, wherein the flange of each tray is partially recessed at an inner side to define a plurality of grooves corresponding to the blocks respectively, the grooves communicate to the top surfaces correspondingly, and the projections of the upper tray stop the blocks of the upper tray from inserting into the corresponding grooves of the lower tray when two trays are stacked in a same direction.
13. The group of trays as claimed in claim 12, wherein the blocks of each tray are positioned in different space.
14. The group of trays as claimed in claim 13, wherein the grooves comprise side grooves and corner grooves, and accordingly the blocks comprise side blocks and corner blocks.
15. The group of trays as claimed in claim 9, wherein the projections are tapered and a width of the projection decreases with increasing distance from the top surface of the flange.
