They are used only for the purpose of describing the present invention and are not intended to indicate or imply that the device or component referred to must have this specific orientation or operate in a specific orientational configuration. Therefore, they should not be construed as limitations of the present invention.

[0033] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] Please see Figures 1-2 As shown, the present invention designs a stacked material unloading device, which includes:

[0035] The frame is equipped with a stacking station and a picking station. The stacking station has several trays containing workpieces, and the picking station is equipped with a chute 19 and a picking robot.

[0036] The first telescopic cylinder 18 is located below the stacking station and is used to abut the first material tray at the bottom of the stacking station.

[0037] The lifting and translation component connects to the frame and can move up and down and translate relative to the frame;

[0038] Support bar 17 connects to the lifting and translating components;

[0039] When the lifting and translating component is driven to move until the support bar 17 abuts against the material tray, the first telescopic cylinder 18 retracts. After the lifting and translating component lowers the height of a single workpiece, the first telescopic cylinder 18 extends, and the lifting and translating component is driven to translate so that the material tray slides along the slide groove 19. The picking robot then takes out the workpiece.

[0040] It should be noted that when the lifting and translating component is driven to move the support bar 17 to abut and support the bottom tray, the first telescopic cylinder 18 retracts. After the lifting and translating component is driven to lower the height of a single workpiece, the first telescopic cylinder 18 extends, the lifting and translating component is driven to translate, and the tray slides along the slide groove 19, realizing the process of automatically taking out a single tray from the stacked trays and transferring it to the picking station. The picking robot is responsible for taking out the workpieces one by one from the trays that have arrived at the picking station, which further improves the automation of picking and greatly reduces the labor intensity.

[0041] Specifically, the lifting and translating assembly includes a slider 13, which is connected to a belt 12. The belt 12 is meshed with a driven gear 11 and a driving gear. The driving gear is connected to a first motor 10. When the first motor 10 is started, the slider 13 can perform translational movement.

[0042] Specifically, a second motor 14 is connected to the slider 13, a first gear 21 is connected to the rotating end of the second motor 14, a rack 15 is meshed with the first gear 21, a support plate 16 is connected to the end of the rack 15 near the stacking station, and a support bar 17 is connected to the support plate 16.

[0043] When the first motor 10 starts, its rotational power is transmitted to the belt 12 through the drive gear, causing the belt 12 to drive the slider 13 to move along the preset track or path. When the second motor 14 starts, the first gear 21 rotates, and the meshing rack 15 moves along its length. The lifting and translating components control the translation and lifting movements through the first motor 10 and the second motor 14 respectively, so that these two actions can be performed independently or simultaneously, greatly improving the flexibility and efficiency of operation.

[0044] Specifically, the stacking and unloading device also includes a recycling station. The stacking station, unloading station and recycling station are set up in sequence. The recycling station is equipped with a second telescopic cylinder 20, which is used to support the empty material tray.

[0045] Specifically, the length of the support bar 17 shall not be less than the sum of the length of the recycling station and the length of the material picking station.

[0046] After all the workpieces in the tray of this invention are removed by the picking robot, the lifting and translating component will be driven to move the tray to the recycling station. Then, the tray will be driven to reach the height of the second telescopic cylinder 20. The second telescopic cylinder 20 extends and abuts against the tray. The length of the support bar 17 is not less than the sum of the length of the recycling station and the length of the picking station. While moving the empty tray to the recycling station, the next tray of the stacking station can also be moved to the picking station, so that picking and recycling of the tray can be carried out at the same time, which greatly improves efficiency.

[0047] Specifically, the frame includes a first guide post assembly, a second guide post assembly, a third guide post assembly, a fourth guide post assembly, and a slide rail 5. The first guide post assembly and the second guide post assembly form a stacking station, the second guide post assembly and the third guide post assembly form a picking station, and the third guide post assembly and the fourth guide post assembly form a recycling station. The first guide post assembly, the second guide post assembly, the third guide post assembly, and the fourth guide post assembly are slidably connected to the slide rail 5.

[0048] Specifically, the stacking and unloading device also includes a first connecting block 6, a threaded rod, a second connecting block, and a third connecting block 9. The first guide post assembly includes two independent first guide posts 1, the second guide post assembly includes two independent second guide posts 2, the third guide post assembly includes two independent third guide posts 3, and the fourth guide post assembly includes two independent fourth guide posts 4. The first connecting block 6 connects the first guide posts 1 and the second guide posts 2, the second connecting block connects the second guide posts 2 and the third guide posts 3, the third connecting block 9 connects the third guide posts 3 and the fourth guide posts 4, and the threaded rod is threadedly connected to the first connecting block 6.

[0049] When the threaded rod of this invention rotates, the first connecting block 6 connected to the threaded rod slides along the slide rail 5. The distance between the two first guide posts 1 and the distance between the two second guide posts 2 will expand or shrink synchronously. The second connecting block connects the second guide post 2 and the third guide post 3. The distance between the two third guide posts 3 will also be consistent with the distance between the two first guide posts 1. The third connecting block 9 connects the third guide post 3 and the fourth guide post 4. The distance between the two fourth guide posts 4 will be consistent with the distance between the two first guide posts 1. By rotating the threaded rod, the size of the stacking station can be easily adjusted to accommodate material trays of different sizes. While adjusting the size of the stacking station, the size of the recycling station and the material picking station will be adjusted synchronously, bringing great convenience to the workers.

[0050] Specifically, the threaded rod is a bidirectional threaded rod 7, with the first end of the bidirectional threaded rod 7 connected to a first connecting block 6, and the second end of the bidirectional threaded rod 7 connected to another first connecting block 6.

[0051] Specifically, the stacking and unloading device also includes a handle 8, which is connected to a bidirectional threaded rod 7.

[0052] When the bidirectional threaded rod 7 is rotated, the two first connecting blocks 6 will move in opposite directions, allowing the operator to quickly adjust the spacing, shortening the adjustment time and improving the adjustment efficiency. The handle 8 provides the operator with a stable gripping point.

[0053] Specifically, the stacking and unloading device also includes a linear module and a conveyor belt. The linear module is connected to a picking robot, which picks up the workpieces from the tray and places them onto the conveyor belt, which then transports the workpieces to the packaging station.

[0054] The linear module provides precise positioning for the picking robot through its high-precision linear motion capability. This ensures that the picking robot can move accurately above the material tray and accurately pick up the target workpiece. The conveyor belt is responsible for transporting the workpiece picked up by the picking robot to the packaging station. The linear module, picking robot and conveyor belt in the stacking and picking device work together to complete the automated process from picking up the material tray to transporting the workpiece to the packaging station.

[0055] Therefore, the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. 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 of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
