Description

Technical Field

[0001] This invention relates to the field of plastic parts processing technology, specifically to a material delivery system for automatic docking of AGV carts with assembly lines. Background Technology

[0002] On automotive plastic parts assembly lines, a wide variety of materials are required for production, including different types of clips, wire harness slots, and decorative covers, and the delivery frequency is high. Currently, manual delivery is commonly used, with operators using hand-pushed forklifts for quantitative delivery. This method consumes a large amount of manpower and is inefficient.

[0003] In existing technologies, AGVs (Automated Guided Vehicles) have become a common choice for upgrading workshop logistics, capable of loading goods and automatically traveling to designated locations along pre-set routes. However, existing ordinary AGVs can only perform transportation functions; in the final docking stage at assembly line workstations, manual loading and unloading of materials is still required. Manual unloading not only consumes manpower and affects production efficiency, but also carries the risk of material mixing and misuse, as plastic parts are typically small and prone to misidentification during manual unloading. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention proposes a material delivery system that automatically docks AGV carts with assembly lines, enabling automatic unloading of materials from AGV carts to the assembly line.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a material delivery system for automatic docking of AGV carts with assembly lines, including an unloading device and a receiving device; The unloading device includes a material placement plate and a material pushing plate. Multiple material placement plates are movably mounted on the AGV trolley, and each material placement plate is equipped with a movable material pushing plate. The receiving device includes a receiving plate, which is movably mounted on the assembly line.

[0006] Materials are loaded onto the placement plate of the AGV (Automated Guided Vehicle) trolley, which then transports them to the assembly line station. During unloading, the placement plate moves to the end of the AGV trolley, while the receiving plate moves at the assembly line station to align with the AGV trolley. The pusher plate then moves, pushing the material off the placement plate and onto the receiving plate. The receiving plate then moves again to deliver the material to the worker's work area.

[0007] The beneficial effects of the material delivery system that automatically docks with the assembly line using AGV carts are: it can automatically complete unloading without manual operation, saving manpower and improving production efficiency.

[0008] Furthermore, the unloading device also includes connecting rods, with one side of the material placement plate hinged to a connecting rod, and the side of the pusher plate also hinged to a connecting rod, with the other ends of the two connecting rods hinged to each other.

[0009] By rotating the connecting rod relative to the material placement plate, another connecting rod can be driven to rotate and move, thereby driving the pusher plate to move on the material placement plate and pushing the material off the material placement plate.

[0010] Furthermore, a transmission gear is fitted at the hinge of the material placement plate and the connecting rod, and a rotatable drive gear is provided on the AGV trolley. The drive gear is connected to a drive motor and can mesh with the transmission gear.

[0011] After the material placement plate that needs to be unloaded moves to the side of the drive gear, the transmission gear meshes with the drive gear, the drive motor drives the drive gear to rotate, and drives the transmission secondary gear to rotate, thereby driving the pusher plate to move, so that the material can be pushed off the material placement plate.

[0012] Furthermore, the AGV is equipped with an unloading port, which is an inclined platform. One end is located next to the drive gear and can fit with the end of the material placement plate at the same height. The other end faces the outside of the AGV and is inclined downward.

[0013] After the material is pushed off the feeding plate, it falls onto the unloading port and slides down under the action of gravity, so that it can slide from the AGV trolley onto the assembly line table.

[0014] Furthermore, a spring hinge is provided at the hinge joint between the material placement plate and the connecting rod.

[0015] After unloading is completed, the material placement plate moves away, the drive gear and the transmission gear disengage, and the transmission gear rotates under the action of the spring hinge, driving the connecting rod and the push plate to reset so that it can be loaded next time.

[0016] Furthermore, the AGV is equipped with an electric guide rail, which is a circular track, and multiple storage plates can be movably mounted on the electric guide rail.

[0017] The circular electric guide rail allows the pallets to move cyclically on the AGV trolley, moving the corresponding pallets to the unloading point according to the materials required by the assembly line.

[0018] Furthermore, the receiving device also includes a screw, which is rotatably disposed below the assembly line table, and the table has a through hole. The bottom surface of the receiving plate is in contact with the table, and its bottom is engaged with the screw, allowing it to move axially as the screw rotates.

[0019] The screw rotation drives the receiving plate to move on the assembly line table. When receiving materials, it can move to the edge of the table to receive materials from the AGV trolley. After unloading, it moves to the side of the operator for easy access.

[0020] Furthermore, the receiving device also includes gear one, gear two, rack and mounting base, two screws are provided in parallel, gear one is located between the two screws and meshes with the two screws on both sides respectively, and gear one is connected to gear two through a rotating shaft; The rotating shaft passes through the mounting base, the rack is movably mounted on the mounting base and is perpendicular to the screw axis, the second gear meshes with the rack, and the rack is located at the bottom of the receiving plate.

[0021] When two screws rotate in the same direction, they drive gear one to move along the axial direction of the screws, which in turn drives the take-up plate to move along the axial direction of the screws via a rotating shaft. When the two screws rotate in opposite directions, they drive gear one to rotate, which in turn drives gear two to rotate via a rotating shaft. With gear two meshing with a rack, it moves the take-up plate on the assembly line table. The mutually perpendicular screws and rack can move the take-up plate to any position on the assembly line table. Attached Figure Description

Detailed Implementation

[0024] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0025] Please see Figures 1 to 5 The present invention provides a material delivery system for automatic docking of AGV carts and assembly lines, including an unloading device 30 and a receiving device 40. The unloading device 30 on the AGV cart 10 unloads the material, and the receiving device 40 on the assembly line 20 receives the material.

[0026] Specifically, such as Figures 1 to 3 As shown, the unloading device 30 includes a material placement plate 31 and a pusher plate 32. Multiple material placement plates 31 are movably mounted on the AGV trolley 10, and each material placement plate 31 is equipped with a movable pusher plate 32. The receiving device 40 includes a receiving plate 41, which is movably mounted on the assembly line 20.

[0027] Materials are loaded onto the material placement plate 31 of the AGV (Automated Guided Vehicle) trolley, which then transports them to the assembly line station. During unloading, the material placement plate 31 moves to the end of the AGV trolley, while the receiving plate 41 moves at the assembly line station to align with the AGV trolley. Subsequently, the pusher plate 32 moves, pushing the material off the material placement plate 31 and onto the receiving plate 41. The receiving plate 41 then moves to deliver the material to the worker's work area. This automated unloading process eliminates the need for manual operation, saving manpower and improving production efficiency.

[0028] Specifically, the unloading device 30 also includes a connecting rod 33. One end of the material placement plate 31 is hinged to the connecting rod 33, and the side of the pusher plate 32 is also hinged to the connecting rod 33. The other ends of the two connecting rods 33 are hinged to each other. By rotating the connecting rod 33 on the material placement plate 31, the other connecting rod 33 can be driven to rotate and move, thereby driving the pusher plate 32 to move on the material placement plate 31 and pushing the material off the material placement plate 31.

[0029] A transmission gear 34 is fitted at the hinge joint between the material placement plate 31 and the connecting rod 33. The AGV trolley is equipped with a rotatable drive gear 35, which is connected to a drive motor 36 and can mesh with the transmission gear 34. During unloading, the material placement plate 31 moves to the side of the drive gear 35, causing the transmission gear 34 to mesh with the drive gear 35. The drive motor 36 drives the drive gear 35 to rotate, which in turn drives the transmission gear 34 to rotate, thereby moving the pusher plate 32 to push the material off the material placement plate 31.

[0030] Specifically, the AGV is also equipped with a discharge port 37, which is sloping. One end of the discharge port 37 is located next to the drive gear 35 and can fit against the end of the material placement plate 31 at the same height. The other end faces the outside of the AGV and is inclined downward. After the material is pushed off the material placement plate 31, it falls onto the discharge port 37 and slides down under the action of gravity, thus sliding from the AGV onto the assembly line table.

[0031] A spring hinge is also provided at the hinge joint between the material placement plate 31 and the connecting rod 33. After unloading is completed, the material placement plate 31 moves away, the drive gear 35 and the transmission gear 34 disengage, and the transmission gear 34 rotates back to reset under the action of the spring hinge, driving the connecting rod 33 and the push plate 32 to reset, so as to load material next time.

[0032] In this embodiment, the AGV is equipped with an electric guide rail 38, which is a rectangular circular track on which multiple placement plates can be movably mounted. The circular electric guide rail 38 allows the placement plates to circulate on the AGV, and the corresponding placement plate 31 is moved to the unloading point according to the materials required by the assembly line.

[0033] Specifically, such as Figure 4 and Figure 5 As shown, the receiving device 40 also includes a screw 42, which is rotatably disposed below the table of the assembly line 20. The table has through holes. The bottom surface of the receiving plate 41 is in contact with the table and its bottom is engaged with the screw 42. It can move along its axial direction as the screw 42 rotates so that it can move to the edge of the table when receiving materials, receive materials from the AGV trolley, and then move to the side of the operator for the operator to pick up.

[0034] The receiving device 40 also includes a first gear 43, a second gear 44, a rack 46, and a mounting base 47. Two screws 42 are arranged in parallel. The first gear 43 is located between the two screws 42 and meshes with the two screws 42 on both sides. The first gear 43 is connected to the second gear 44 via a rotating shaft 45. The rotating shaft 45 passes through the mounting base 47. One side of the rack 46 meshes with the second gear 44, and the other side is embedded in the mounting base 47 and can move axially. The rack 46 is also perpendicular to the axial direction of the screws 42 and is fixedly connected to the bottom of the receiving plate 41. In addition, a limiting rod 48 is fixedly provided below the platform along the axial direction of the screws 42. The mounting base 47 is slidably connected to the limiting rod 48 to limit the travel trajectory of the mounting base 47.

[0035] Both screws 42 are driven by a motor. When both screws 42 rotate in the same direction, they drive gear 43 to move along the axial direction of the screws 42. At this time, gear 43 and gear 44 do not rotate. Since the side of the rack 46 is embedded in the mounting base 47, it can drive the take-up plate 41 to move along the axial direction of the screws 42 through the rotating shaft 45, the mounting base 47, and the rack 46. When the two screws 42 rotate in opposite directions, they drive gear 43 to rotate. At this time, gear 43 drives gear 44 to rotate through the rotating shaft 45, and neither moves. Through the cooperation of gear 44 and rack 46, rack 46 moves within the mounting base 47 and drives the take-up plate 41 to move. The axes of the screws 42 and rack 46 are perpendicular to each other, which is equivalent to the x-axis and y-axis of a rectangular coordinate system. Therefore, it can move the take-up plate 41 to any position on the assembly line table.

[0036] The working principle of the aforementioned material delivery system for automatic docking of AGV carts with assembly lines is as follows: Materials are loaded onto the placement plate 31 of the AGV cart 10, and the AGV cart 10 transports the materials to the workstation of the assembly line 20. During unloading, the placement plate 31 to be unloaded moves along the electric guide rail 38 to the drive gear 35, engaging the driven gear. Simultaneously, two screws 42 rotate, driving the receiving plate 41 to move on the table of the assembly line 20 to align with the unloading port 37 of the AGV cart. The drive motor 36 drives the drive gear 35 to rotate, causing the driven gear and connecting rod 33 to rotate, causing the pusher plate 32 to push the material off the placement plate 31. The material slides through the unloading port 37 onto the receiving plate 41.

[0037] Using the above-mentioned material delivery system that automatically docks AGV carts with the assembly line, the unloading of materials from the AGV carts to the assembly line can be completed automatically, eliminating the need for manual material handling, saving manpower, and enabling more efficient production.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
