Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure.

[0022] Based on the embodiments described in this disclosure, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this disclosure.

[0023] refer to Figures 1-6 .

[0024] This invention provides a high-efficiency automatic loading and unloading device, comprising a frame 1, a transfer mechanism 2, a transport mechanism 3, a first hopper mechanism 4, a second hopper mechanism 5, and a loading and unloading mechanism 6. The transfer mechanism 2 includes a first Z-axis linear drive mechanism 20 disposed on one side of the frame 1 and a transfer tray 21 drivenly connected to the first Z-axis linear drive mechanism 20. The transport mechanism 3 includes a first Y-axis linear drive mechanism 30 disposed on one side of the frame 1 and a transport platform 31 drivenly connected to the first Y-axis linear drive mechanism 30. The first hopper mechanism 4 and the second hopper mechanism 5 each include a second Z-axis linear drive mechanism 40 disposed on one side of the frame 1 and a hopper tray 41 drivenly connected to the second Z-axis linear drive mechanism 40. The loading and unloading mechanism 6 includes a second Y-axis linear drive mechanism 60 disposed on the top of the frame 1 and a clamping mechanism 61 drivenly connected to the second Y-axis linear drive mechanism 60. One end of the transfer tray 21 and the hopper tray 41 is provided with a transport avoidance window 210, and the transport platform 31 can enter and exit the transport avoidance window 210.

[0025] Its working principle is as follows: material loading and finished product unloading operations can be carried out manually or by AGV at the transfer mechanism 2. Both materials and finished products are placed on pallets. When loading materials, several pallets containing materials are stacked and placed on the transfer pallet 21. The first Y-axis linear drive mechanism 30 drives the transport platform 31 to move below the transfer pallet 21. The first Z-axis linear drive mechanism 20 drives the transfer pallet 21 to descend. The transport platform 31 will enter the transport avoidance window 210 of the transfer pallet 21 until the bottom material pallet on the transfer pallet 21 is supported by the transport platform 31 and separated from the transfer pallet 21. The second Z-axis linear drive mechanism 40 of the first hopper mechanism 4 drives the hopper pallet 41 to descend to a height lower than the transport platform 31. The first Y-axis linear drive mechanism 40 drives the hopper pallet 41 to descend to a height lower than the transport platform 31. The linear drive mechanism 30 drives the transport platform 31 into the transport avoidance window 210 of the hopper pallet 41 until the transport platform 31 moves above the hopper pallet 41. Then, the second Z-axis linear drive mechanism 40 of the first hopper mechanism 4 drives the hopper pallet 41 to rise, allowing the material pallet on the transport platform 31 to be transferred to the hopper pallet 41 of the first hopper mechanism 4. This continues until the topmost material pallet rises to the loading / unloading mechanism 6. The clamping mechanism 61, driven by the second Y-axis linear drive mechanism 60, moves back and forth. After clamping the topmost material pallet, the clamping mechanism 61 moves along the second Z-axis of the first hopper mechanism 4... The linear drive mechanism 40 lowers the hopper pallet 41 to a certain height, allowing the top material pallet to separate from the next layer, thus conveying the material pallet to the next workstation for loading. When unloading finished products, the pallet containing the finished product is stacked on the hopper pallet 41 of the second hopper mechanism 5 by the loading / unloading mechanism 6. The first Y-axis linear drive mechanism 30 moves the transport platform 31 to below the hopper pallet 41 of the second hopper mechanism 5. The second Z-axis linear drive mechanism 40 of the second hopper mechanism 5 then lowers the hopper pallet 41 to a height below the transport platform 31, allowing the transport platform 31 to move into the hopper pallet 41. The transport platform 31 is driven backward by the first Y-axis linear drive mechanism 30 to avoid obstructing the material storage tray 41 of the second material storage mechanism 5. After the material storage tray 41 of the second material storage mechanism 5 rises and resets, the transport platform 31, driven by the first Y-axis linear drive mechanism 30, transports the finished product tray to the upper side of the transfer tray 21. The transfer tray 21 is then driven upward by the first Z-axis linear drive mechanism 20, and the transfer tray 21 receives the finished product tray. The finished product tray can then be removed from the transfer tray 21 manually or by AGV, completing the unloading operation. The first material storage mechanism 4 and the second material storage mechanism 5 can alternately perform material loading and unloading operations, achieving unloading and unloading without stopping the machine. By combining the loading and unloading functions, the production line length can be reduced, the loading and unloading efficiency can be effectively improved, and the equipment cost can be reduced.

[0026] Based on the above embodiments, the frame 1 includes four columns 10 and a top plate 11 fixedly connected between the tops of the four columns 10. The top plate 11 has loading and unloading windows 110, and the top two sides of the top plate 11 are provided with upright plates 12. The second Y-axis linear drive mechanism 60 includes a C-shaped slide 600 slidably connected between the two upright plates 12 along the Y-axis direction and a Y-axis drive cylinder 601 disposed on the upright plate 12 and drivenly connected to the C-shaped slide 600. The clamping mechanism 61 includes two clamping components 610 disposed opposite to each other. The clamping component 610 includes a clamping cylinder 611 disposed at one end of the C-shaped slide 600 and an L-shaped picking arm 612 drivenly connected to the clamping cylinder 611. When the Y-axis drive cylinder 601 is working, it can drive the clamping mechanism 61 to move back and forth. When the pallet is between the two L-shaped picking arms 612, the clamping cylinders 611 on both sides drive the L-shaped picking arms 612 to move forward, so that the two L-shaped picking arms 612 can clamp the pallet, which facilitates the separation of the two pallets and the transport of the pallet.

[0027] Based on the above embodiments, the first Z-axis linear drive mechanism 20 includes a Z-axis slide 200 slidably connected between two columns 10 along the Z-axis direction, a Z-axis cylinder 201 disposed on one of the columns 10 and drivenly connected to the Z-axis slide 200, and a transfer plate 21 fixedly connected to the Z-axis slide 200. When the Z-axis cylinder 201 is working, it can drive the Z-axis slide 200 to move up and down, thereby driving the transfer plate 21 to rise and fall.

[0028] Based on the above embodiments, the frame 1 also includes two bottom beams 13 fixedly connected between the bottoms of the two columns 10. The first Y-axis linear drive mechanism 30 includes a Y-axis support beam 300 fixedly connected between the two bottom beams 13 and a Y-axis synchronous belt slide 301 disposed on the top of the Y-axis support beam 300. The transport platform 31 is drivenly connected to the Y-axis synchronous belt slide 301. When the Y-axis synchronous belt slide 301 is working, it can drive the transport platform 31 to move back and forth, realizing the transfer of the pallet between the transfer pallet 21 and the hopper pallet 41.

[0029] Based on the above embodiments, the second Z-axis linear drive mechanism 40 includes a Z-axis mounting base 400 disposed at the bottom of the top plate 11 and a Z-axis synchronous belt slide 401 disposed on the Z-axis mounting base 400. A connecting plate 410 is fixedly connected to one side of the hopper tray 41, and the connecting plate 410 is drivenly connected to the Z-axis synchronous belt slide 401. When the Z-axis synchronous belt slide 401 is working, it can drive the hopper tray 41 to move up and down, thereby driving the pallet to lift and lower for loading and unloading operations.

[0030] Based on the above embodiments, a material blocking mechanism 7 is also included. The material blocking mechanism 7 includes a pushing mechanism 70 and a first baffle 71 fixedly connected to the connecting upright plate 410. The pushing mechanism 70 includes an X-axis pushing cylinder 700 and a second baffle 701 drivenly connected to the X-axis pushing cylinder 700. A support 14 is fixedly connected to a column 10, and the X-axis pushing cylinder 700 is disposed on the support 14. When the transfer pallet 21 horizontally transports the pallet, the X-axis pushing cylinder 700 drives the second baffle 701 to move closer to the first baffle 71. The pallet moves between the first baffle 71 and the second baffle 701, which helps to stabilize the pallet and prevent it from tipping over during transport.

[0031] Based on the above embodiments, a number of baffles 411 are distributed around the top of the material hopper pallet 41 around the handling avoidance window 210, which can limit the pallet and prevent the pallet from tipping over.

[0032] Based on the above embodiment, guide plates 211 are provided on both sides of the top of the transfer pallet 21. One end of the guide plate 211 is provided with a guide slope 211a, and the end of the guide plate 211 away from the guide slope 211a is connected to a limiting plate 212. A proximity sensor 213 is provided on the limiting plate 212. When a material pallet is placed on the transfer pallet 21, the material pallet enters the transfer pallet 21 under the guidance of the guide slopes 211a on both sides until the material pallet touches the inner side of the limiting plate 212. At this point, the proximity sensor 213 can sense that the material has arrived and send a signal to the control system.

[0033] Based on the above embodiments, positioning posts 310 are provided on both sides of the top of the transport platform 31, and positioning holes corresponding to the positioning posts 310 are provided on the bottom of the pallet. When the pallet is placed on the transport platform 31, the positioning posts 310 are inserted into the positioning holes of the pallet to position the pallet and ensure that the pallet is placed in an accurate position.

[0034] The above embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
