DETAILED DESCRIPTION

[0017] like Figures 1 to 5As shown, in this embodiment, the present invention includes a guide fixed base frame 1, a lifting and loading assembly 2, and a conveyor assembly 3. The lifting and loading assembly 2 includes a lifting frame 21, a lifting support frame 22, and a transverse support plate 23. The lifting frame 21 is connected to one side of the upper end of the guide fixed base frame 1. The lifting frame 21 is equipped with a lifting module 24. The lifting support frame 22 is connected to the movable end of the lifting module 24. The transverse support plate 23 is connected to the upper end surface of the lifting support frame 22 via a plurality of slide rails 25. The lifting support frame 22 is equipped with a transverse module 4. The transverse module 4 drives a plurality of trays 26 on the transverse support plate 23 to mate with a plurality of products 5 on the conveyor assembly 3 on one side of the guide fixed base frame 1. As can be seen, the motor reducer in the lifting module 24 starts to rotate, driving the synchronous wheel connected to it to rotate. The synchronous wheel pair is connected to the reducer at one end and to a screw at the other end. The power is transmitted to the screw through a synchronous belt, causing it to rotate. The rotating screw drives the corresponding nut assembly to move up and down linearly. The lead screw is secured to the fixed plate by upper and lower lead screw support assemblies. The lifting support frame 22, connected to the nut assembly, moves up and down accordingly, driving the transverse support plate 23 affixed to it to rise and fall synchronously, thereby conveying the product to the desired height. The lifting support is connected to the Z-axis guide rails on both sides of the lead screw, ensuring smooth and rock-free operation during the lifting process.

[0018] like Figure 2 As shown, in this embodiment, the conveyor assembly 3 includes a base frame 31, a material rack 32, and shelves 33. The material rack 32 is connected to the upper end of the base frame 31. Several groups of shelves 33 are arranged in an array on both sides of the material rack 32. The products 5 are placed on two corresponding groups of shelves 33. The lifting module 24 drives the trays 26 to engage with the lower ends of the corresponding products 5. As can be seen, the main function of the conveyor assembly 3 is to store materials. Materials of different shapes and sizes can be stored as needed. The material rack 32 is reinforced with multiple corner brackets and shelf reinforcement plates to ensure stability during transportation.

[0019] like Figure 1 and Figure 4As shown, in this embodiment, positioning modules 6 are provided on both sides of the upper end of the guide fixed base frame 1. The positioning modules 6 include positioning support frames 61, positioning cylinders 62, and lifting plates 63. Two sets of positioning support frames 61 are provided on both sides of the guide fixed base frame 1. The positioning cylinders 62 are provided on the lower end surfaces of the positioning support frames 61 and cooperate with the lifting plates 63 on the upper ends of the positioning support frames 61. The positioning cylinders 62 drive the lifting plates 63 to cooperate with both sides of the base frame 31. As can be seen, when the conveying assembly 3 is pushed into the interior of the guide fixed base frame 1, the lifting plates 63 cooperate with the base frame 31 to achieve positioning, thereby preventing the conveying assembly 3 from shifting during the material removal process.

[0020] like Figure 2 and Figure 4 As shown, in this embodiment, a plurality of positioning pins 64 are provided on the upper end of the lifting plate 63, and positioning side plates 34 are provided on both sides of the base frame 31. The plurality of positioning pins 64 respectively cooperate with the positioning hole structures on the corresponding positioning side plates 34. Thus, the plurality of positioning pins 64 can stably connect the base frame 31 to the guide fixed base frame 1 without deviation.

[0021] like Figure 1 and Figure 4 As shown, in this embodiment, a guide module 7 is provided on one side of the positioning module 6. The guide module 7 includes a guide plate 71 and guide wheels 72. Several groups of guide wheels 72 are provided on the guide side of the upper end surface of the guide plate 71. Several groups of guide wheels 72 cooperate with both sides of the base frame 31. As can be seen, when the conveying assembly 3 is pushed into the upper material level of the guide fixed base frame 1, the two groups of guide wheels 72 of the guide module 7 with opposite tilt directions guide the conveying assembly 3 to the center, thereby achieving higher locking accuracy of the positioning module 6.

[0022] like Figure 2 As shown, in this embodiment, the lower end surface of the material rack 32 is provided with a transport positioning plate 35, and the transport positioning plate 35 cooperates with the external transport trolley. It can be seen that the transport positioning plate 35 can enable the conveying assembly 3 to cooperate with the external AGV trolley for transport transfer.

[0023] like Figure 2As shown, in this embodiment, the material rack 32 is equipped with two product storage positions. Several sets of shelves 33 are arranged in an array on either side of the two product storage positions. Trays 26 are installed on both sides of the upper end surface of the transverse support plate 23. The two sets of trays 26 are matched with the products 5 in the corresponding product storage positions. Thus, the material rack 32 is equipped with two rows and two columns of four sets of shelves 33. Each column contains eight fixed plates, which can store a total of 32 products. Each layer of shelves 33 is equipped with three positioning blocks to secure the products 5 and prevent damage during loading, unloading, and transportation. Handles are also provided to facilitate manual operation.

[0024] like Figure 5 As shown, in this embodiment, the transverse movement module 4 includes a transverse movement cylinder 41 and a rotating gear 42. The transverse movement cylinder 41 is installed at the lower end of the lifting support frame 22. The movable end of the transverse movement cylinder 41 is engaged with the rack structure at the lower end of the transverse movement support plate 23 through the rotating gear 42. As can be seen, the transverse movement support plate 23 is driven by the gear meshing transmission to achieve the effect of transferring the material.

[0025] like Figure 2 As shown, in this embodiment, a plurality of groups of casters 8 are provided at the lower end of the chassis 31. It can be seen that the casters 8 enable the conveying assembly 3 to be transferred as a whole.

[0026] The working principle of the present invention is as follows: S1, the conveying assembly 3 with full material is pushed into the upper material position of the lifting guide fixed base frame 1, and is guided by a plurality of guide wheels 72 on both sides. After the conveying assembly 3 is pushed into the fixed end of the guide fixed base frame 1, the lifting plate 63 rises and drives a plurality of positioning pins 64 to limit the position with the positioning hole structure on the positioning side plate 34; S2. Then, the lifting module 24 drives the lifting support frame 22 to the outer side of the uppermost layer of the material rack 32, and the transverse cylinder 41 drives the rotating gear 42 to rotate. Through the meshing action of the gears, the transverse support plate 23 moves laterally and enters the interior of the material rack 32, and the two sets of trays 26 are respectively positioned at the lower ends of the corresponding products 5; S3. When the positioning sensor on the tray 26 identifies the positioning point of the product 5, the lifting module 24 rises a certain distance, so that the two groups of trays 26 lift the corresponding products 5 and make them separate from the limit of the edge of the shelf 33; S4. After the lifting operation is completed, the transverse cylinder 41 is reversed to move the transverse support plate 23 in the opposite direction. The tray 26 lifts the product 5 and separates it from the rack 32, so that the product can be taken out and transferred to the loading station. S5. After the loading operation is completed, the lifting module 24 drives the lifting support frame 22 to move to the second material removal position, and repeats the above steps to achieve positioning and material removal of multiple groups of products.

[0027] Although the embodiments of the present invention are described with practical solutions, they do not limit the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
