[0001] The present invention relates to the technical field of logistics handling, and in particular to an autonomous handling device which is convenient for loading and unloading. Background Art

[0002] Autonomous handling devices refer to intelligent handling equipment or robots that perform cargo handling tasks. They are usually equipped with advanced perception, navigation and control systems and can perform cargo handling tasks autonomously without human intervention. Their main applications include warehouse management, production line material handling, pharmaceutical and food industries, etc., for warehousing, outbound, picking and handling of materials, thereby improving the degree of automation and management efficiency of handling.

[0003] When carrying out the existing handling operation, the supporting part of the existing handling device must first be moved into the pallet at the bottom of the goods, and then the hydraulic part is activated to lift the supporting part, thereby lifting the goods and completing the handling preparation work. During the handling process, the friction between the goods and the pallet, and between the pallet and the supporting part is mainly relied on to prevent the goods from falling from the handling device.

DETAILED DESCRIPTION

[0034] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0035] See also Figures 1 to 11 As shown, the present invention provides an embodiment: an autonomous handling device that is easy to load and unload, including a device body 1, a connecting base 2 is fixedly connected to the outer wall of the device body 1, a connecting frame 31 is fixedly connected to the bottom of the connecting base 2, and a support frame 32 is symmetrically fixedly connected to the side of the connecting frame 31 away from the connecting base 2. It is characterized in that: a lifting assembly 4 is provided inside the connecting base 2, a connecting assembly 5 is provided on the top of the connecting frame 31, and a loading and unloading assembly 6 is symmetrically provided on the top of the support frame 32. The loading and unloading assembly 6 includes an adaptive mechanism 61, a clamping mechanism 62 and a reset mechanism 63;

[0036] The adaptive mechanism 61 includes a support base 611, a movable plate 612, a movable block 613 and a signal transmitter 614. The movable plate 612 and the movable block 613 are symmetrically slidably connected to the interior of the support base 611. The signal transmitter 614 is fixedly connected to the top of the movable block 613. A micro switch is provided on the top of the signal transmitter 614. A gear 1 615 is provided inside the support base 611 through the reset mechanism 63. A rack 1 616 is fixedly connected to the side where the movable plate 612 and the movable block 613 are close to each other. The rack 1 616 is meshed with the gear 1 615. The interior of the support base 611 is rotatably connected to a limit rod 617, which passes through the movable plate 612 and the movable block 613.

[0037] The clamping mechanism 62 includes a mounting plate 621 and a mounting sleeve 622. The mounting sleeve 622 is fixedly connected to the top of the mounting plate 621, and the mounting sleeve 622 is slidably connected to the inside of the support seat 611. The top of the movable block 613 is fixedly connected to the mounting seat three 625. The internal rotation of the mounting seat three 625 is connected to the clamping rod 626. The internal rotation of the movable block 613 is connected to the worm 624. The worm 624 is slidably connected to the outside of the limiting rod 617. The outside of the limiting rod 617 is fixedly connected to the gear two 629. The top of the mounting plate 621 is fixedly connected to the rack two 628. The top of the rack two 628 is fixedly connected to the rubber pad. The rack two 628 and the gear two 629 are meshed with each other. The bottom of the clamping rod 626 is provided with a worm gear groove meshing with the worm 624.

[0038] In practical application, the embodiment of the present invention is as follows: Figure 1 and Figure 2 As shown, the device body 1 is started and moved to the vicinity of the location where the goods are to be loaded and unloaded. The connecting seat 2 on the outer wall of the device body 1 provides stable support for the connecting frame 31 and the supporting frame 32 below.

[0039] Next, the lifting assembly 4 inside the connecting base 2 starts to operate, and adjusts the height of the connecting assembly 5 and the loading and unloading assembly 6 according to the height of the cargo, ensuring that the loading and unloading assembly 6 can accurately dock with the cargo pallet;

[0040] like Figure 5 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10As shown, when the loading and unloading assembly 6 approaches the cargo pallet, the pallet pushes the movable plate 612. Since the rack 1 616 on the side where the movable plate 612 and the movable block 613 are close to each other is meshed with the gear 1 615, and the gear 1 615 is installed inside the support base 611 through the reset mechanism 63, the movement of the movable plate 612 will drive the gear 1 615 to rotate, thereby causing the movable block 613 to move synchronously. During this process, the limit rod 617 that passes through the movable plate 612 and the movable block 613 serves to limit the movement direction of the two and ensure stability. As the movable block 613 moves, the signal transmitter 614 on its top also moves. When the pallet moves between the movable plate 612 and the movable block 613, the micro switch on the top of the signal transmitter 614 is triggered, indicating that the pallet is in the appropriate initial clamping position.

[0041] At the same time, if Figures 7 to 11 As shown, the worm 624 connected to the internal rotation of the movable block 613 moves with the movable block 613. Since it is slidably connected to the outside of the limit rod 617, and the outside of the limit rod 617 is fixedly connected to the second gear 629, the second rack 628 on the top of the mounting plate 621 is meshed with the second gear 629. At this time, the lifting component 4 is started to drive the loading and unloading component 6 to move upward, and the limit rod 617 is rotated by the meshing of the second rack 628 and the second gear 629 (because the second rack 628 is fixed to the top of the mounting plate 621, so when the loading and unloading component 6 moves Because the support seat 611 is blocked by the pallet, the rack 2 moves upward relative to the gear 2 629, pushing the gear 2 629 to rotate). Since the worm 624 is slidably connected to the limit rod 617, the rotating worm 624 will engage with the worm gear groove at the bottom of the clamping rod 626, causing the clamping rod 626 to rotate around the mounting seat 3 625, thereby achieving stable clamping of the pallet and the goods (in this process, the top rubber pad of the rack 2 628 fits with the rack 1 616 at the bottom, which can ensure that the position of the movable block 613 remains unchanged through friction).

[0042] Among them, the reset mechanism 63 can ensure that the gear 1 615 returns to the initial position after loading and unloading is completed, and drives the movable plate 612 and the movable block 613 to reset, so as to facilitate stable clamping during the next loading and unloading.

[0043] like Figure 3 、 Figure 5 and Figure 6As shown, the connecting assembly 5 includes a fixed seat 52 slidably connected to the connecting seat 2, and the fixed seat 52 is symmetrically fixedly connected to the mounting seat 2 on one side away from the connecting seat 2. The interior of the mounting seat 2 57 is rotatably connected to a connecting rod 55, and the end of the connecting rod 55 away from the mounting seat 2 57 is rotatably connected to the mounting seat 1 56. An adjustment mechanism 51 is provided between the two mounting seats 1 56, and the mounting plates 621 are fixedly connected to the mounting seat 1 56. The interior of the connecting seat 2 is symmetrically slidably connected to a connecting block 58, and the two connecting blocks 58 are fixedly connected to the same limit plate 53 on one side away from the fixed seat 52. The outer wall of the limit plate 53 is fixed. A servo motor 2 54 is fixedly installed, and the connecting blocks 58 are fixedly connected to the fixed seat 52. The adjusting mechanism 51 includes a movable seat 511. The movable seat 511 is symmetrically and slidingly connected to a movable rod 514 inside. The movable rod 514 is fixedly connected to the mounting seat 1 56. A spring 1 515 is fixedly connected between the movable rod 514 and the movable seat 511. The fixed seat 52 is internally rotatably connected to a screw rod 2 512. The movable seat 511 is internally fixedly connected to a connecting sleeve 513. The screw rod 2 512 and the connecting sleeve 513 form a spiral pair transmission. The end of the screw rod 2 512 close to the limit plate 53 is fixedly connected to the servo motor 2 54 through a coupling.

[0044] In actual use, the embodiment of the present invention is activated based on the actual needs of the pallet and cargo. Servo motor 54 drives screw 512 to rotate via a coupling. Because screw 512 and connecting sleeve 513 form a helical pair transmission, screw 512 can drive the movable seat 511 to move synchronously. When the movable seat 511 moves, the movable rod 514 slidably connected therein drives the mounting seat 1 56 to move synchronously. Mounting seat 1 56 is rotationally connected to mounting seat 2 57 via connecting rod 55, and mounting seat 2 57 is fixed to fixed seat 52. Therefore, the movement of mounting seat 1 56 causes the movable rod 514 to move within the movable seat 511, thereby adjusting the spacing of the adaptive mechanism 61 fixed thereto to accommodate pallets and cargo of different widths, thereby improving overall applicability.

[0045] like Figure 3 and Figure 4 As shown, the lifting assembly 4 includes a protective cover 41 fixedly connected to the top of the connecting base 2, a servo motor 42 is fixedly installed on the top of the protective cover 41, and a screw rod 43 is symmetrically connected to the inside of the connecting base 2 for rotation. The tops of the two screw rods 43 are fixedly connected to a sprocket 44, and a transmission chain 45 is connected between the two sprockets 44. The screw rods 43 form a spiral pair transmission with the connecting block 58, and the top of one of the screw rods 43 passes through the protective cover 41 and is fixedly connected to the output shaft of the servo motor 42 through a coupling.

[0046] When the embodiment of the present invention is actually used, the servo motor 42 is started autonomously according to demand, so that the output shaft of the servo motor 42 drives one of the screw rods 43 to rotate through the coupling. Since the two screw rods 43 are connected by the sprocket 44 and the transmission chain 45, the two screw rods 43 rotate synchronously. The rotating screw rod 43 drives the connecting component 5 and the loading and unloading component 6 to move synchronously through the spiral pair transmission between the screw rod 43 and the connecting block 58, so as to adapt to pallets of different heights and the loading and unloading of goods. At the same time, it can also provide the adaptive mechanism 61 and the clamping mechanism 62 to realize the power of clamping the pallet and the goods.

[0047] like Figure 7 and Figure 10 As shown, two groups of four protrusions 623 are symmetrically fixedly connected to the inner wall of the support base 611. The protrusions 623 are all slidably connected to the inside of the installation sleeve 622. A spring 2 627 is fixedly connected between the top of the protrusion 623 and the installation sleeve 622.

[0048] When the embodiment of the present invention is actually used, the sliding of the protrusion 623 inside the mounting sleeve 622 can not only ensure the stability of the movement, but also limit the moving stroke. In addition, the spring 2 627 can drive the clamping mechanism 62 to reset at the top of the adaptive mechanism 61, so as to facilitate the release of the clamping and facilitate the unloading of the pallet and materials.

[0049] like Figure 11 As shown, the reset mechanism 63 includes a mounting shaft 631 rotatably connected to the inside of the support base 611 , a mounting bracket 632 is symmetrically fixedly connected to the outside of the support base 611 , and a torsion spring 633 is fixedly connected between the mounting shaft 631 and the mounting bracket 632 .

[0050] In actual application of the embodiment of the present invention, when the movable plate 612 is moving, it will drive the gear 1 615 to rotate. The rotation of the gear 1 615 can not only drive the movable block 613 to move through the bottom movable plate 612, but also drive the torsion spring 633 to be tightened in the mounting bracket 632, so as to facilitate the reset of the movable plate 612 and the movable block 613 after loading and unloading, thereby ensuring the convenience of loading and unloading next time.

[0051] like Figure 7 As shown, waist-shaped grooves are symmetrically opened inside the installation sleeve 622, and the installation shaft 631 is slidably connected to the two waist-shaped grooves.

[0052] In actual application of the embodiment of the present invention, the waist-shaped groove provided on the mounting sleeve 622 can enable the mounting shaft 631 to move within the mounting sleeve 622 .

[0053] As shown in the figure, the outer side of the limiting rod 617 is symmetrically fixedly connected with a guide ridge, and the inner wall of the worm 624 is symmetrically provided with a guide groove adapted to the guide ridge.

[0054] In actual application of the embodiment of the present invention, the sliding connection between the guide ridges and the guide grooves allows the worm 624 to slide outside the limiting rod 617 and drive the worm 624 to rotate synchronously when the limiting rod 617 rotates.

[0055] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.
