Therefore, they should not be construed as limiting the present invention.

[0029] like Figure 1-Figure 2As shown, an AGV loading device of an embodiment of the present invention includes an AGV loading device 1, the AGV loading device 1 includes an AGV trolley 11, a bracket 12 and a material basket 13, the bracket 12 includes a support plate 121 and support legs 122, the material basket 13 is detachably arranged on the support plate 121, the support legs 122 are provided at the bottom of the support plate 121, the AGV trolley 11 has a lifting mechanism 111, and the AGV trolley 11 is used to lift the support plate 121 and the material basket 13 through the lifting mechanism 111.

[0030] Specifically, the AGV trolley 11, also known as the Automated Guided Vehicle, is an unmanned vehicle. The lifting mechanism 111 can be extended and retracted along the Z direction, and the lifting height is about 100 mm. The material basket 13 is used to carry materials and can be a frame-type structure with an open top, and the top opening is used for feeding and discharging. The support plate 121 of the bracket 12 is arranged horizontally, and its size can be slightly larger than the bottom wall size of the material basket 13 to ensure the support stability of the bracket 12 to the material basket 13. The four corners of the support plate 121 are respectively provided with support legs 122 to ensure the support stability of the support plate 121. When the lifting mechanism 111 of the AGV trolley 11 is lowered to the lowest position, the overall height of the AGV trolley 11 is not higher than the support height of the support legs 122, ensuring that the AGV trolley 11 can move to the bottom of the support plate 121 to lift the support plate 121 and the material basket 13.

[0031] In this embodiment, a material basket 13 containing processing materials such as aluminum alloy is placed on a pallet 121 of a bracket 12, and the support legs 122 at the bottom of the pallet 121 can be supported on the ground. When the material basket needs to be transported, the AGV trolley 11 moves to the bottom of the pallet 121, and raises the jacking mechanism 111 to lift the bracket 12 and the material basket 13, with the support legs 122 suspended in the air. Afterwards, the AGV trolley 11 moves to transport the material basket 13 to a set position such as the lifting device 2, thereby realizing the automated transportation of the material basket 13. Therefore, it is possible to reduce manual labor intensity and logistics costs, and improve the production efficiency of die-casting parts. Moreover, since the material basket 13 and the pallet 121 of the bracket 12 are detachable, the material basket 13 can be lifted alone for unloading. For example, the lifting device 2 can only lift the material basket 13 without lifting the entire bracket 12 and the material basket 13. , which is conducive to reducing the specifications of the lifting device 2; after the lifting device 2 lifts the material basket 13 to a high place and pours the material into the furnace, the lifting device 2 places the empty material basket 13 on the bracket 12, and the AGV trolley 11 moves the empty material basket 13 and the bracket 12 away, thus completing the entire loading process; in addition, compared with the solution of placing the material basket 13 directly on the AGV trolley 11, in the material temporary storage area or when loading is not required, the jacking mechanism 111 of the AGV trolley 11 descends, the supporting legs 122 of the bracket 12 touch the ground, and the material basket 13 is supported by the support plate 121, and the AGV trolley 11 can be moved from under the support plate 121, avoiding long-term occupation of the AGV trolley 11 and causing waste of resources. In other words, a smaller number of AGV trolleys 11 can be set to realize the transportation of more material baskets 13, thereby improving the utilization rate of the AGV trolley 11.

[0032] like Figure 1-Figure 2 As shown, optionally, the AGV loading device also includes a first positioning member 14, which is arranged on the support plate 121, and the first positioning member 14 includes two positioning plates 141 arranged at angles to each other, and the two positioning plates 141 of the first positioning member 14 are respectively used to position and fit with the two side walls adjacent to the material basket 13.

[0033] Specifically, the first positioning member 14 can be positioned at a corner of the support plate 121, allowing for a relatively small size. The two positioning plates 141 of the first positioning member 14 are arranged perpendicularly to each other. That is, the two positioning plates 141 of the first positioning member 14 can respectively engage with two adjacent side walls of the basket 13 to position the corners of the basket 13. By positioning the first positioning members 14 at at least two corners of the support plate 121, accurate positioning of the basket 13 and the support plate 121 can be achieved. Preferably, the first positioning members 14 can be positioned at each of the four corners of the support plate 121 to ensure positioning stability.

[0034] In this embodiment, when the material basket 13 is completed to prepare the materials or the lifting device 2 has finished dumping the materials in the material basket 13 and the material basket 13 is placed on the pallet 121, the first positioning member 14 on the pallet 121 can be used to position the material basket 13 to ensure that the material basket 13 returns to its correct position.

[0035] In some other embodiments, the first positioning member 14 may include a positioning boss provided on the supporting plate 121 and a positioning groove provided on the bottom wall of the basket 13 .

[0036] like Figure 3 、 Figure 4 and Figure 6 As shown, optionally, the feeding system also includes a lifting device 2, the lifting device 2 includes a frame 21, the frame 21 includes a fixed frame 211 and a lifting frame 212, the two fixed frames 211 are arranged opposite to each other, the lifting frame 212 is arranged between one end of the two fixed frames 211, and the lifting frame 212 is used for vertical lifting relative to the fixed frames 211, the AGV trolley 11 is used to enter the interior of the frame 21 from between the other ends of the two fixed frames 211, the material basket 13 is provided with a second positioning member 15, and the lifting frame 212 is provided with a third positioning member 23 matching the second positioning member 15, and the material basket 13 is used to dock and position with the lifting frame 212 through the second positioning member 15 and the third positioning member 23.

[0037] Specifically, the two fixed frames 211 of the rack 21 can be spaced apart along the Y direction to form a space between the two for the AGV trolley 11 to enter. Each fixed frame 211 is formed by connecting multiple horizontally and vertically cross-arranged rods. The lifting frame 212 is arranged between the two fixed frames 211 at one end along the negative direction of the X-axis, that is, the rear end. The AGV trolley 11 carries the bracket 12 and the material basket 13, and can enter the interior of the rack 21 from the two fixed frames 211 at one end along the positive direction of the X-axis, that is, the front end.

[0038] The lifting frame 212 can be connected to the motor via a chain transmission mechanism, and the motor and chain transmission mechanism can be used to drive the lifting frame 212 to rise and fall vertically relative to the frame 21, that is, along the Z direction. When the second positioning member 15 and the third positioning member 23 cooperate with each other, the lifting frame 212 can be docked and positioned between the material basket 13 on the AGV trolley 11.

[0039] In this embodiment, the AGV trolley 11 can transport the bracket 12 and the material basket 13 containing materials to the interior of the frame 21, and make the second positioning member 15 on the material basket 13 cooperate with the third positioning member 23 on the lifting frame 212 to position the material basket 13 on the AGV trolley 11 on the lifting frame 212, that is, to achieve the docking positioning of the material basket 13 and the lifting frame 212, so that the material basket 13 can be lifted up and down with the lifting frame 212 to pour the material in the material basket 13 into the furnace.

[0040] In addition, equipment such as the furnace is usually arranged on the negative side of the frame 21 along the X-axis, that is, behind the frame 21, to avoid affecting the AGV trolley 11 entering and exiting the frame 21. Therefore, by arranging a lifting frame 212 between the rear ends of the two fixed frames 211, on the one hand, it is beneficial for the AGV trolley 11 to automatically complete the docking with the lifting frame 212 in the process of entering the frame 21 from the front of the frame 21, such as completing the insertion of the positioning sleeve and the positioning fork described later; on the other hand, the lifting frame 212 can be flipped backward after lifting the material basket 13 to a certain height to pour the material in the material basket 13 into the furnace, making loading more convenient.

[0041] It should be noted that after the material basket 13 is docked and positioned with the lifting frame 212 through the second positioning member 15 and the third positioning member 23, the AGV trolley 11 can be moved from under the pallet 121 and leave the frame 21 to avoid affecting the operation of the lifting device 2; when the material in the material basket 13 is dumped and the material basket 13 is lowered to a lower place, the AGV trolley 11 moves to under the pallet 121 to move the bracket 12 and the material basket 13 away.

[0042] like Figure 1 、 Figure 2 and Figure 4 As shown, optionally, the second positioning member 15 is a positioning sleeve, the third positioning member 23 is a positioning fork, the extension direction of the positioning sleeve is parallel to the movement direction of the AGV trolley 11 entering the frame 21, the positioning fork is used to fit with the positioning sleeve in a clearance, and / or, a guide portion 231 is provided at one end of the positioning fork away from the lifting frame 212.

[0043] In this embodiment, one end of the positioning sleeve is closed and the other end is open. The extension direction of the positioning sleeve can be parallel to the movement direction of the AGV trolley 11 into the frame 21. When the AGV trolley 11 carries the material basket 13 toward the lifting device 2, the open end of the positioning sleeve on the material basket 13 can be directed toward the front of the movement of the AGV trolley 11. When the AGV trolley 11 enters the frame 21 from the outside, the positioning fork can be smoothly inserted from the open end of the positioning sleeve to achieve positioning and docking of the two. Moreover, compared with providing positioning forks on the material basket 13 and providing positioning sleeves on the lifting frame 212, this embodiment provides positioning sleeves on the material basket 13 and positioning forks on the lifting frame 212, thereby avoiding the AGV loading device 1 from being too large due to the positioning forks protruding from the material basket 13, which interferes with surrounding equipment during movement.

[0044] The clearance between the positioning fork and the positioning sleeve reduces the difficulty of their cooperation, avoiding the failure of positioning the material basket 13 and the lifting frame 212 due to the inability to align the positioning sleeve and the positioning fork when the AGV trolley 11 is moving with the material basket 13, thereby improving the loading efficiency.

[0045] The end of the positioning fork away from the lifting frame 212 can be set into a tapered structure to form a guide portion 231, so that the positioning fork can be smoothly inserted into the positioning sleeve under the guidance of the guide portion 231, thereby improving the assembly efficiency of the two.

[0046] In some embodiments, positioning sleeves can be set on one of the two opposite side walls of the basket 13, and the positioning forks and positioning sleeves are set one by one. Multiple sets of positioning sleeves and positioning forks are used for plug-in positioning to ensure the positioning accuracy of the basket 13 and the lifting frame 212.

[0047] like Figure 3 、 Figure 4 and Figure 6 As shown, optionally, the lifting device 2 also includes a material guide plate 22, and the material guide plate 22 is fixedly mounted on the lifting frame 212. The material basket 13 has a material opening 131. When the material basket 13 is docked and positioned with the lifting frame 212, the material guide plate 22 is located at the edge of the material opening 131 of the material basket 13.

[0048] Specifically, when the basket 13 is positioned vertically, the top of the basket 13 has a material opening 131. The lifting device 2 may further include a tilting mechanism mounted on the frame 21. When the basket 13 is lifted to a higher position, the tilting mechanism drives the basket 13 and the lifting frame 212 to tilt toward the rear of the frame 21, thereby dumping the material in the basket 13 into the furnace behind the frame 21. When the basket 13 is docked and positioned with the lifting frame 212 and the basket 13 is positioned vertically, the guide plate 22 extends upward from the bottom toward the material opening 131.

[0049] In this embodiment, when the material basket 13 is lifted to a high position and flipped toward the rear of the frame 21, the lifting frame 212 flips along with the material basket 13, and the guide plate 22 is tilted downward. The material poured out from the material port 131 of the material basket 13 can enter the furnace smoothly under the guidance of the guide plate 22, preventing the material from spilling outside the furnace.

[0050] like Figure 3 As shown, optionally, the material guide plate 22 includes two side plates 221 and a connecting plate 222. The two side plates 221 are arranged in parallel, so that the direction in which the AGV trolley 11 enters the frame 21 is the calibration direction. One end of the two side plates 221 along the calibration direction is respectively connected to the connecting plate 222. The two side plates 221 and the connecting plate 222 are respectively used to fit with the corresponding side walls of the material basket 13.

[0051] In this embodiment, the calibration direction is from front to back, and the side panels 221 are arranged along the XZ plane. A connecting plate 222 is connected between the two side panels 221 at one end of the calibration direction, more precisely, at the rear ends of the two side panels 221. The two side panels 221 and the connecting plate 222 together form a U-shaped structure. The connecting plate 222 is substantially parallel to the lifting frame 212. By fixing the connecting plate 222 to the lifting frame 212, a convenient connection between the material guide plate 22 and the lifting frame 212 can be achieved.

[0052] When the AGV 11 carries the bracket 12 and basket 13 into the frame 21, or when the basket 13 is docked and positioned with the lifting frame 212, the left, right, and rear sidewalls of the basket 13 respectively mate with the two side panels 221 and the connecting plate 222. When the basket 13 is turned over to dump the material into the furnace, the U-shaped guide plate 22 prevents material from spilling from multiple directions, improving the material guiding effect.

[0053] like Figure 3-Figure 6 As shown, optionally, the lifting device 2 further includes a guide mechanism 24 , and the two fixed frames 211 are respectively provided with the guide mechanism 24 on one side facing each other, and the bracket 12 is used to enter the interior of the frame 21 under the guidance of the guide mechanism 24 .

[0054] Specifically, the guide mechanism 24 is disposed near the bottom of the fixed frame 211. When the AGV 11, carrying the bracket 12 and the material basket 13, enters the frame 21 from the front to the rear, the left and right sides of the bracket 12 contact the corresponding guide mechanism 24, allowing the bracket 12 to smoothly enter the frame 21 under the guidance of the guide mechanism 24, while the material basket 13 and the bracket 12 remain relatively stationary, thus ensuring that the material basket 13 can smoothly enter the frame 21. In addition, the guiding and limiting function of the guide mechanism 24 also facilitates the docking and positioning of the material basket 13 and the lifting frame 212.

[0055] like Figure 5 As shown, optionally, the guide mechanism 24 includes a guide wheel 241, and the two fixed frames 211 are respectively provided with a plurality of the guide wheels 241 on the side facing each other, and the plurality of guide wheels 241 on both sides are arranged in a one-to-one correspondence; along the calibration direction, the distance between the corresponding two guide wheels 241 gradually decreases, and / or, among the plurality of guide wheels 241 on the same side, the setting height of some guide wheels 241 is higher than the setting height of another part of the guide wheels 241.

[0056] Specifically, the axis of the guide wheel 241 of the guide mechanism 24 is arranged along the Z direction, that is, the guide wheel 241 can rotate around the Z axis, and the multiple guide wheels 241 on each side are arranged in sequence along the front and rear directions. Along the calibration direction, that is, from the front to the rear, the distance between the two guide wheels 241 arranged opposite to each other on the left and right sides gradually decreases, that is, the multiple guide wheels 241 on the left and right sides form a trumpet shape, thereby improving the guiding effect on the bracket 12.

[0057] The multiple guide wheels 241 on the same side can be located at different heights to respectively contact the support plate 121 and the support legs 122 of the bracket 12 to improve the guiding effect of the bracket 12.

[0058] In some other embodiments, the guide mechanism 24 may be a guide plate, and along the calibration direction, the distance between the guide plates on both sides gradually decreases. When the AGV trolley 11 carries the bracket 12 and the material basket 13 into the frame 21 from front to back, the guide plates on both sides can have a better guiding effect on the bracket 12.

[0059] like Figure 5 As shown, optionally, the lifting device 2 also includes a lifting plate 25, and the two lifting plates 25 are arranged on the side of the two fixed frames 211 facing each other, and the two lifting plates 25 are respectively connected to the two fixed frames 211, and the opposite ends of the support plate 121 are respectively provided with a lap plate 123, and the lap plate 123 is used to overlap with the lifting plate 25 up and down, and when the support plate 121 and the lifting plate 25 are overlapped up and down, the support leg 122 is suspended.

[0060] In this embodiment, the guide mechanism 24 also includes a mounting plate 242. The two mounting plates 242 are respectively installed on the corresponding fixed frame 211. The mounting plates 242 can be set horizontally. The guide wheel 241 is installed on the mounting plate 242. The axle of the guide wheel 241 is rotatably connected to the mounting plate 242. The mounting plates 242 on the left and right sides are provided with a lifting plate 25 at one end close to each other. The lifting plate 25 is set horizontally to provide better flatness. After the material basket 13 on the AGV trolley 11 is docked and positioned with the lifting frame 212, the lifting mechanism 111 of the AGV trolley 11 is lowered so that the overlapping plates 123 on the left and right sides of the pallet 121 are placed on the lifting plates 25, and the supporting legs 122 are suspended in the air, so as to achieve horizontal lifting of the bracket 12, and avoid the problem that the positioning accuracy between the material basket 13 and the pallet 121 is poor due to poor ground flatness, and the material basket 13 cannot be accurately placed on the pallet 121 after it is lifted to the top of the frame 21 and the material is unloaded.

[0061] Optionally, the feeding system also includes a controller, and the lifting device 2 is used to lift the material basket 13 on the AGV trolley 11 and pour the material in the material basket 13 into the furnace. The controller is respectively communicated with the AGV trolley 11, the lifting device 2 and the furnace material quantity detection device.

[0062] In this embodiment, the controller may be a PLC controller. The furnace material quantity detection device may detect the height or weight of the material in the furnace to determine whether the material in the furnace is sufficient.

[0063] When the furnace material quantity detection device detects that there is insufficient material in the furnace, the controller controls the AGV trolley 11 to move. Specifically, the AGV trolley 11 lifts the bracket 12 and the material basket 13 containing the material, and sends the material basket 13 to the lifting device 2, so that the material basket 13 is docked and positioned with the lifting frame 212. The AGV trolley 11 sends a relevant signal to the controller that the material has arrived at the lifting device 2. After that, the controller controls the motor of the lifting device 2 to drive the lifting frame 212 and the material basket 13 to rise. After the material in the material basket 13 is thrown into the furnace, the lifting frame 212 and the empty material basket 13 descend, and the empty material basket 13 is placed on the bracket 12. The controller sends a loading completion signal to the AGV trolley 11 based on the signal fed back by the motor, and the AGV trolley 11 transports the bracket 12 and the material basket 13 to the batching area.

[0064] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
