[0058] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. However, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without any creative effort shall fall within the scope of protection of the present invention.

[0059] like Figure 1-3As shown, the metal material tray of the present invention is made of a rigid material as a whole, preferably a strip metal sheet continuously punched and prepared, specifically comprising an integrally formed bottom frame 1 and a plurality of integrally formed panels 2, wherein the panels 2 are fixed to the bottom frame 1 at intervals, and the number of panels 2 is determined according to the size of the bottom frame 1, and gaps 12 are formed between adjacent panels 2, preferably, the width of each gap 12 is equal. The bottom frame 1 is an integrally formed rectangular parallelepiped or cube, preferably, the bottom frame 1 is a rectangular parallelepiped frame consisting of two side walls, a first side wall 3 and a second side wall 4 (such as Figure 2 As shown, the length of the first side wall 3 is shorter than that of the second side wall 4). After the panel 2 is welded to the bottom frame 1, the upper surface of the metal material support plate is smooth and will not scratch the material in contact with it, which is conducive to the stable placement and removal of the material.

[0060] Both end portions of the support frame 18 of the panel 2 are provided with process holes 8, which are through holes. The process holes 8 at each end of the support frame 18 can be one or two horizontally symmetrical process holes 8. The ends of the panel 2 are supported on the plate edge 13 on the bottom frame 1, and the panel 2 is fixedly connected to the plate edge 13 through the process holes 8. The fixed connection method can be manual welding, machine welding or fixing by screws. Alternatively, the support frame 18 can also be provided with a support fixing portion, and the support fixing portion is provided with a process hole 8. The length of the support fixing portion is the same as the width of the plate edge 13. The two structures cooperate with each other, making it convenient to weld the panel 2 to the plate edge 13 through the process holes 8. The presence of the process holes 8 can, on the one hand, enable the welding electrode to deeply contact the plate edge 13, and on the other hand, can reduce the weight of the support frame 18.

[0061] The side walls of the bottom frame 1 are evenly provided with a number of symmetrically distributed reinforcing ribs 6. The reinforcing ribs 6 are formed by the inward depression of the side walls themselves and can be circular, rectangular or elliptical in shape, so as to achieve the effect of reinforcing the side walls of the bottom frame 1 themselves. Furthermore, an intelligent panel 7 is provided in the middle of the side walls of the bottom frame 1. For the transportation and placement of material pallets, if materials need to be stored, the material name or number or other settings for quickly locking the corresponding material storage location can be set through the intelligent panel 7 on the pallet. When the material pallet is stored in a specific area and is ready for use, the material location can be quickly locked according to the material name or number.

[0062] like Figure 4The panel 2 is composed of two mutually parallel support frames 18 and a groove 9, and the two support frames 18 and the groove 9 are integrally formed. Among them, the groove 9 is located in the middle of the two support frames 18. The depth of the groove 9 is related to the thickness of the upper end of the forklift fork mouth, that is, its bottom position is not higher than the top of the forklift hole. The ends of the two outer side walls of the support frame 18 are bent inward horizontally, and the bent part is on the same horizontal line as the bottom of the groove 9, so as to ensure that when the fork is transporting the material pallet, the bottom of the groove 9 is in horizontal contact with the fork. The bottom of the groove 9 is provided with evenly distributed circular holes 19, and the edges of the circular holes 19 are smooth, which can ensure that the overall weight of the panel 2 is reduced and the cleaning of debris or dust is facilitated without affecting the overall bearing capacity of the panel 2.

[0063] Furthermore, reinforcing ribs 11 are evenly distributed on the inner and outer walls of the support frame 18. The reinforcing ribs 11 are formed by the inward depression of the support frame 18 itself and can be circular, oval, elongated, or rectangular in shape, thereby strengthening the strength of the support frame 18. Reinforcing holes are evenly distributed along the longitudinal direction of the upper surface of the support frame 18. These reinforcing holes can be circular, oval, elongated, or rectangular in shape, and are preferably V-shaped holes 10. Although the V-shaped holes 10 are through holes, the material forming the V-shaped holes 10 does not escape from the support frame 18, but is folded inward to form a curled edge. This structure can effectively disperse the material pressure and enhance the load-bearing capacity of the material tray without reducing the material or weight of the support frame 18 itself. The two V-shaped holes 10 provided on the surface of the support frame 18 on each panel 2 are of the same shape but in opposite directions. This structure can not only strengthen the material of the support frame 18 itself, but also prevent the panel 2 from being installed in the wrong direction, thereby improving installation efficiency.

[0064] like Figure 5 As shown, each support frame 18 is composed of inner and outer side walls. One side of the inner side wall has the same depth as the groove 9, and the lower end of the outer side wall is horizontally bent inward. The bent portion is located on the same horizontal line as the bottom of the groove 9. This structure ensures that the bottom of the panel 2 is smooth, has no sharp ends, and will not scratch other objects, such as forklifts or other objects. At the same time, the bent structure of the horizontal portion contacts the bottom of the groove 9 and the forklift, which can support and strengthen the load-bearing capacity of the pallet. The material forming the V-shaped through hole 10 does not leave the support frame 18 and is located inside the support frame 18. The interior of the reinforcing rib 11 is a raised long oval.

[0065] like Figure 6-8As shown, the upper portion of the base frame 1 is pressed inward around the edges to form four frame edges. The distance between the panel edge 13 and the upper end of the base frame 1 is the same as the thickness of the panel 2. The panel 2 is fixedly connected to the base frame 1 via the panel edge 13, preferably by welding. The lower end of the side wall of the base frame 1 is bent inward around the edges to form a lower horizontal support portion. The end of the lower horizontal support portion is provided with a bend 20. The horizontal portion of the lower horizontal support portion is used to support the metal material tray. The bend 20 not only prevents it from being exposed and scratched by other objects, but also serves to enhance the overall stability and load-bearing capacity of the metal material tray.

[0066] like Figure 3 、 14 As shown, when looking down at one side wall of the bottom frame 1, it can be seen that the plate edge 13 of the bottom frame 1 is integrally connected to the frame edge, the bottom of the bottom frame 1 is flat, and the structural area is small, the space occupied is small, the metal material tray uses less material, and the preparation cost is low.

[0067] like Figure 1-3 As shown in Figures 9-11, the first side wall 3 and the second side wall 4 of the bottom frame 1 are both provided with two identical first O-shaped forklift holes 5. The size and distance of the two first O-shaped forklift holes 5 are set according to the forklift forks. The first O-shaped forklift holes 5 are formed as follows. Figure 10 The blanking and bending structure shown is formed, and the blanking and bending structure is a fishtail support structure 15 and the same upper and lower first reinforcement plates 14. After bending, the two sides and upper and lower parts of the first O-shaped forklift hole 5 are respectively formed to strengthen the support structure, which together play the role of firmly supporting the material tray and preventing the material tray from being deformed due to stress. Figure 11 As shown, the first reinforcing plate 14 on the upper side of the first O-shaped forklift hole 5 is folded inward and overlaps with the upper plate edge 13 of the bottom frame 1, thereby reinforcing the bottom frame 1 above the first O-shaped forklift hole 5. The first reinforcing plate 14 on the lower side of the first O-shaped forklift hole 5 is located on the horizontal structure of the lower horizontal support portion of the bottom frame 1, thereby reinforcing the strength of the bottom frame 1 below the first O-shaped forklift hole 5; Figure 11 As shown, the two identical sides of the first O-shaped forklift hole 5 are fishtail-type support structures 15. The side ends of the fishtail-type support structure 15 are integrally connected to the first O-shaped forklift hole 5, the upper end is vertically fixedly connected to the plate edge 13 of the bottom frame 1, and the lower end is vertically fixedly connected to the bend 20 of the lower horizontal support portion, which plays a role in stabilizing the bottom frame 1 through its own structure, making the material pallet as a whole not easily deformed and improving the overall bearing capacity of the material pallet.

[0068] The shapes of the forklift holes provided on the first side wall 3 and the second side wall 4 may also be different, such as Figure 12-14As shown. Further, the forklift hole on the first side wall 3 can also be a second O-shaped forklift hole 21, and the forklift hole on the second side wall 4 can be a C-shaped forklift hole 16. At this time, Figure 15-18 As shown, the width of the upper horizontal support connecting portion of the bottom frame 1 is smaller than that of the lower horizontal support portion. There is a V-shaped structure between the adjacent two side walls of the bottom frame 1, which facilitates the combination of the four side walls of the bottom frame 1 into an integral shape.

[0069] Further, such as Figure 19 The second O-shaped forklift hole 21 shown is formed by Figure 20 The blanking and bending structure shown is formed by the same tail-type support structure 17 on both sides of the second O-shaped forklift hole 21, and the different first reinforcement plate 14 and second reinforcement plate 23. The second reinforcement plate 23 is wider than the first reinforcement plate 14, but shorter in length. Figure 22 As shown, the first reinforcing plate 14 on the upper side of the second O-shaped forklift hole 21 is folded inward and overlaps with the upper plate edge 13 of the bottom frame 1, thereby reinforcing the support strength of the plate edge 13 of the bottom frame 1. The second reinforcing plate 23 on the lower side of the second O-shaped forklift hole 21 is located on the horizontal structure of the lower horizontal support portion of the bottom frame 1, reinforcing the strength of the bottom frame 1 below the second O-shaped forklift hole 21. The two identical sides of the second O-shaped forklift hole 21 are the tail-shaped support structure 17. The top of the tail-shaped support structure 17 is integrally connected to the second O-shaped forklift hole 21, the upper end is vertically fixedly connected to the plate edge 13 of the bottom frame 1, and the lower end is vertically connected to the horizontal part of the lower horizontal support portion. The lower end of the tail-shaped support structure 17 is located on the inner side of the bend 20, which stabilizes the bottom frame 1 through its own structure, making the material tray as a whole less prone to deformation and improving the overall load-bearing capacity of the material tray.

[0070] Further, such as Figure 21 As shown. The C-shaped forklift hole 16 is formed by a punched and bent structure, which is composed of the same straight tail support structure 22 on both sides of the C-shaped forklift hole 16, and the first reinforcing plate 14 on the upper side, respectively forming the reinforcing support structure on both sides and the upper side of the C-shaped forklift hole 16, which together play the role of firmly supporting the material pallet and preventing the material pallet from deforming due to force. Furthermore, the first reinforcing plate 14 on the upper side of the C-shaped forklift hole 16 is folded inward and overlaps with the upper plate edge 13 of the bottom frame 1, playing the role of reinforcing the bottom frame 1 above the C-shaped forklift hole 16; the top end of the straight tail support structure 22 is integrally connected to the C-shaped forklift hole 16, the upper end is vertically fixedly connected to the plate edge 13 of the bottom frame 1, and the lower end is vertically connected to the horizontal part of the lower horizontal support part, and is located inside the bend 20, playing the role of stabilizing the bottom frame 1 frame body through its own structure, making the material pallet as a whole not easy to deform and improving the overall bearing capacity of the material pallet.

[0071] When in use, the materials are stacked on the material pallet, and then the forklift's fork is inserted into the first O-shaped forklift hole 5 or the C-shaped forklift hole 16 to transport and place the material pallet. If the materials need to be stored, the material name or number or other settings for quickly locking the corresponding material storage location can be set through the intelligent panel 7 on the pallet. When the material pallet is stored in a specific area and is ready for use, the material location can be quickly locked according to the material name or number.

[0072] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
