Fig. 1 is a schematic perspective view of a tray according to an embodiment of the present invention. As shown in fig. 1, the tray includes a tray main body 10 and a tray side wall 20.

The tray body 10 is provided with at least one product channel 11 depressed downward. Specifically, the tray body 10 includes a plurality of product slots 11, and the plurality of product slots 11 are arranged in an array. Wherein the shape, size and number of the product slots 11 can be adapted according to the parts to be carried.

The outer circumference of the tray body 10 is rectangular, for example, rectangular or square. In this embodiment, the four corners of tray main part 10 is the fillet, and the four corners of avoiding tray main part 10 in the transportation is too sharp-pointed, personnel or equipment are transported in the fish tail. It should be understood that the shape and size of the outer periphery of the tray body 10 may be adaptively adjusted.

The tray side wall 20 encloses and blocks the periphery of the tray main body 10, and is fixedly connected with the periphery of the tray main body 10. The upper end surface 26 of the tray side wall 20 is connected with the periphery of the tray main body 10, and the lower end surface 27 of the tray side wall 20 is positioned below the tray main body 10. Specifically, the included angle between the tray side wall 20 and the tray main body 10 is an obtuse angle. That is, the tray side wall 20 extends downward and outward from the outer periphery of the tray main body 10. The lower end surface 27 of the tray side wall 20 has a size larger than the upper end surface 26 of the tray side wall 20, which facilitates stacking of a plurality of trays.

The first side 21 and the opposite second side 22 of the tray sidewall 20 are provided with a first fool-proof structure 23 protruding from outside to inside and a second fool-proof structure 24 protruding from outside to inside. The distance from the lower end surface of the second fool-proof structure 24 to the lower end surface 27 of the tray side wall 20 is greater than the distance from the lower end surface of the first fool-proof structure 23 to the lower end surface 27 of the tray side wall 20. In this embodiment, the lower end surface of the second fool-proof structure 24 is a predetermined dimension from the lower end surface 27 of the tray side wall 20. The lower end surface of the first fool-proofing structure 23 and the lower end surface 27 of the tray side wall 20 are flush or substantially flush.

Fig. 2 is a schematic view of the trays stacked in the same direction. Fig. 3 is a front view of the trays stacked in the order of trays according to the embodiment of the present invention. As shown in fig. 2 and 3, when two trays are stacked in a tray-by-tray manner, the protruding portions of the first fool-proof structures 23 on the first side 21 and the second side 22 of the tray sidewall 20 of one tray cannot fall into the recessed portions of the first fool-proof structures 23 corresponding to the first side 21 and the second side 22 of the tray sidewall 20 of the other tray; and the protruding portions of the second fool-proofing structures 24 on the first and

second sides

21, 22 of the tray side walls 20 of one of the trays can fall into the recessed portions of the corresponding second fool-proofing structures 24 on the first and

second sides

21, 22 of the tray side walls 20 of the other of the trays. However, since the first fool-proofing structure 23 has limited the two trays from overlapping when stacked in order, the second fool-proofing structure 24 of one tray is not yet in the recessed portion of the second fool-proofing structure 24 of the other tray at this time.

In the embodiment of the present invention, the cross-sectional dimension of the first fool-proof structure 23 is gradually increased from top to bottom.

The cross-sectional dimension of the second fool-proofing structure 24 is larger than the largest cross-sectional dimension of the first fool-proofing structure 23. Because the size of the upper end face of the first fool-proof structure 23 is smaller than the size of the lower end face of the first fool-proof structure 23, when the first fool-proof structure 23 of one tray is placed on the first fool-proof structure 23 of another tray, the lower end face of the first fool-proof structure 23 of the tray located on the upper layer cannot fall into the first fool-proof structure 23 of the first fool-proof structure of the tray located on the lower layer. The lower end surface of part of the first fool-proof structure 23 of the tray located at the upper layer is located on the tray main body 10 of the lower layer. The distance between the two tray bodies 10 is equal to the height of the tray side walls 20. Therefore, when two trays are stacked one by one, the two trays cannot be stacked together.

Fig. 4 is a schematic view of the staggered tray stacking according to the embodiment of the present invention. Fig. 5 is a front view of the staggered tray stacking of the embodiment of the present invention. As shown in fig. 4 and 5, when two of the trays are stacked, the protruding portion of the first fool-proofing structure 23 on the first side 21 of the tray sidewall 20 of one of the trays can fall into the recessed portion of the second fool-proofing structure 24 on the second side 22 of the tray sidewall 20 of the other tray; and the protruding portion of the second fool-proofing structure 24 on the first side 21 of the tray side wall 20 of one of the trays cannot fall into the recessed portion of the second fool-proofing structure 24 on the second side 22 of the tray side wall 20 of the other of the trays.

When the first side 21 of one pallet is placed on the second side 22 of the other pallet, the first fool-proofing structure 23 of the first side 21 of one pallet is opposite to the second fool-proofing structure 24 of the second side 22 of the other pallet, and the second fool-proofing structure 24 of the first side 21 of one pallet is opposite to the first fool-proofing structure 23 of the second side 22 of the other pallet. At this time, the bottom portion of the first fool-proof structure 23 of the tray located at the upper level is located in the recessed portion of the second fool-proof structure 24 of the tray located at the lower level, that is, the lower end face of the second fool-proof structure 24 located at the lower level supports the lower end face of the first fool-proof structure 23, so that a predetermined distance is maintained between the tray main body 10 located at the upper level and the tray main body 10 located at the lower level, and the distance between the tray main body 10 located at the upper level and the tray main body 10 located at the lower level is substantially equal to the distance between the lower end face of the second fool-proof structure 24 and the upper end face 27 of the tray side wall 20. That is, the distance between the upper and lower adjacent tray bodies 10 is substantially equal to the height of the second fool-proofing structure 24. By controlling the height of the second fool-proof structure 24 to be larger than the height of the part, the distance between the two trays is larger than the height of the part, and the part is prevented from being crushed by the bottom of the tray on the upper layer.
