Description

Technical Field

[0001] This utility model relates to the field of material transportation technology, and in particular to an automated material transportation device. Background Technology

[0002] In manufacturing, warehousing and logistics, food processing, and many other fields, the transfer and delivery of materials is one of the core links to ensure the continuity and efficiency of the production process. With the expansion of industrial production scale and the increasing demand for refined management, higher and higher requirements are being placed on the automation, accuracy, and stability of material transportation. Currently, there are two main ways to achieve material transportation: one is to rely on manual labor with simple tools (such as handcarts, hydraulic forklifts, etc.), and the other is to use preliminary automated transportation devices, such as fixed-rail conveyor vehicles, belt conveyors, and automated guided vehicles (AGVs).

[0003] Currently, existing AGVs are generally only suitable for traveling on flat ground. When the AGV travels on a sloping road (a few factories may have ramps at the connection between different areas), the pallet on which the goods are placed will also tilt. If the tilt angle is large, the pallet may slip off the AGV, causing the materials on the pallet to scatter or even break. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automated material handling device that solves the problem that when existing AGV trolleys travel on inclined roads, the top tray cannot be leveled, which may cause materials to fall and be damaged.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automated material handling device includes;

[0007] The AGV (Automated Guided Vehicle) itself is existing technology and can move along preset guide marks;

[0008] The support mechanism includes a support plate, which is a plate-like structure made of stainless steel. Materials can be placed on the top surface of the support plate, and the support plate can rotate along a first axis parallel to the ground.

[0009] The drive mechanism can drive the support plate to rotate on the first axis.

[0010] Preferably, the support mechanism includes a connecting plate, which is fixedly connected to the top surface of the AGV trolley body by screws. The connecting plate is a plate-shaped structure made of stainless steel, and a guide groove is provided on the top surface of the connecting plate for installing moving components and lead screws.

[0011] Preferably, both inner walls of the guide groove are fixedly connected to limit slide rails by screws, and a grating scale is fixedly connected to one side of the guide groove. The grating scale, together with the reading head, positions the moving component. The limit slide rail, together with the limit slider, makes the movement of the moving component in the guide groove more stable.

[0012] Preferably, the top surface of the connecting plate is fixedly connected to two bearing seats by welding. A metal movable shaft is rotatably connected between the two bearing seats by bearings. A support plate is fixedly connected to the surface of the metal movable shaft by welding connecting rods. The support plate can cooperate with the metal movable shaft to rotate based on the bearing seats.

[0013] Preferably, a triangular structure is fixedly connected to the bottom of the support plate. The three interior angles of the triangular structure are 30°, 60° and 90° respectively. The triangular structure is made of stainless steel and its surface is coated with lubricating oil. A MEMS tilt sensor is fixedly connected to the end of the support plate away from the metal movable shaft by screws. The lubricating oil is existing technology. The MEMS tilt sensor is existing technology. It is electrically connected to the AGV body through a flexible circuit and can detect the tilt angle of the support plate.

[0014] Preferably, the drive mechanism includes a drive component and a moving component. The drive component includes a servo motor, which is fixedly connected to the side wall of the AGV body by screws. The output end of the servo motor is fixedly connected to a drive bevel gear, which meshes with a driven bevel gear. The driven bevel gear is fixedly connected to a lead screw. The servo motor is electrically connected to the AGV body through a flexible circuit. The servo motor can drive the drive bevel gear to rotate, which in turn drives the driven bevel gear to rotate, and the driven bevel gear to drive the lead screw to rotate, thus enabling the servo motor to drive the lead screw to rotate.

[0015] Preferably, the moving component includes a connecting block, which is a block structure made of stainless steel. A nut is fixedly connected to the axis of the connecting block by welding. Limiting sliders are fixedly connected to both side walls of the connecting block by screws. The limiting sliders can cooperate with the limiting slide rail to limit the moving direction of the moving component. The nut can cooperate with the lead screw to make the moving component move as a whole in the guide groove.

[0016] Preferably, the top surface of the connecting block is fixedly connected to two bearing seats by welding, and a roller is rotatably connected between the two bearing seats by bearings. The roller is in pressure contact with the triangular structure.

[0017] Preferably, the limiting slider is slidably connected to the limiting slide rail, the nut is threadedly connected to the lead screw, the side wall of the connecting block is fixedly connected to the reading head by screws, the lead screw is adapted to the grating scale, the reading head is electrically connected to the AGV trolley body through a flexible line, and the flexible line has sufficient movement margin in the guide groove.

[0018] Preferably, a protective shell is fixedly connected to one end of the AGV body by welding. The protective shell surrounds the servo motor, the driving bevel gear and the driven bevel gear. The protective shell is a block structure made of stainless steel, with a hollow cavity on its inner side. The servo motor is located inside the hollow cavity, which is used to protect the drive components.

[0019] This application uses a servo motor to drive a moving component to move within a guide groove. The position of the moving component is detected by a reading head in conjunction with a grating scale. When the moving component changes position, the rollers can contact different positions of the triangular structure, causing the rollers to press against the triangular structure and drive the support plate to rotate based on the axle seat. This causes the pallet located above the support plate to rotate as well. The angle of rotation of the support plate is equal to the slope of the ramp, ensuring that the support plate and the pallet are always in a horizontal state. This solves the problem that existing AGVs cannot level the pallet on top when traveling on inclined surfaces, which may cause materials to fall and be damaged. Attached Figure Description

[0035] like Figure 2 , Figure 3 and Figure 4As shown, the support mechanism 200 includes a connecting plate 201, which is fixedly connected to the top surface of the AGV trolley body 100 by screws. The connecting plate 201 is a plate-shaped structure made of stainless steel. A guide groove 202 is provided on the top surface of the connecting plate 201. The guide groove 202 is used to install the moving component 320 and the lead screw 314.

[0036] like Figure 2 , Figure 3 and Figure 4 As shown, both inner walls of the guide groove 202 are fixedly connected to the limit slide rail 203 by screws. A grating scale 204 is fixedly connected to one side of the guide groove 202. The grating scale 204, together with the reading head 324, positions the moving component 320.

A MEMS tilt sensor 209 is fixedly connected to the end of the support plate 207 away from the metal movable shaft 206 by screws. The lubricating oil is existing technology. The MEMS tilt sensor 209 is existing technology. It is electrically connected to the AGV body 100 through a flexible circuit. It can detect the tilt angle of the support plate 207.

[0039] like Figure 2 and Figure 4As shown, the drive mechanism 300 includes a drive assembly 310 and a moving assembly 320. The drive assembly 310 includes a servo motor 311, which is fixedly connected to the side wall of the AGV body 100 by screws. The output end of the servo motor 311 is fixedly connected to a drive bevel gear 312, which meshes with a driven bevel gear 313. The driven bevel gear 313 is fixedly connected to a lead screw 314.

The servo motor 311 can drive the drive bevel gear 312 to rotate, the drive bevel gear 312 can drive the driven bevel gear 313 to rotate, and the driven bevel gear 313 can drive the lead screw 314 to rotate, so that the servo motor 311 can drive the lead screw 314 to rotate.

[0040] like Figure 2 and Figure 4 As shown, the moving component 320 includes a connecting block 321, which is a block structure made of stainless steel.

The limit sliders 323 can cooperate with the limit rail 203 to limit the moving direction of the moving component 320. The nut 322 can cooperate with the lead screw 314 to make the moving component 320 move as a whole within the guide groove 202.

[0041] like Figure 2 and Figure 4 As shown, the top surface of the connecting block 321 is fixedly connected to two bearing seats 325 by welding.

[0044] This application transports materials by having the AGV trolley body 100 move along fixed guide marks. The pallet containing the materials can be placed on the triangular structure 208. When the MEMS tilt sensor 209 detects that the support plate 207 is tilted, the AGV trolley body 100 travels to the inclined ramp and can start the servo motor 311 to drive the moving component 320 to move within the guide groove 202. The position of the moving component 320 is detected by the reading head 324 in conjunction with the grating scale 204. When the moving component 320 changes position, the roller 326 can contact different positions of the triangular structure 208, causing the roller 326 to press against the triangular structure 208 and drive the support plate 207 to rotate based on the axle seat 205. This causes the pallet located above the support plate 207 to rotate as well (the maximum rotation angle of the support plate 207 is 25 degrees, which is suitable for 25-degree ramps). The rotation angle of the support plate 207 is equal to the slope of the ramp, so that the support plate 207 and the pallet are always in a horizontal state.

[0045] When facing an opposite slope, this application only requires the AGV trolley body 100 to move backwards to repeat the above process to achieve the leveling operation of the support plate 207.

[0046] The above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of the present invention.
