Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are 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, comprising a device body 1, a connecting seat 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 seat 2, and a supporting frame 32 is symmetrically fixedly connected to the side of the connecting frame 31 away from the connecting seat 2, characterized in that: a lifting component 4 is arranged inside the connecting seat 2, a connecting component 5 is arranged on the top of the connecting frame 31, and a loading and unloading component 6 is symmetrically arranged on the top of the supporting frame 32, and the loading and unloading component 6 includes an adaptive mechanism 61, a clamping mechanism 62 and a reset mechanism 63;

[0036] The adaptive mechanism 61 includes a support seat 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 inside of the support seat 611. The signal transmitter 614 is fixedly connected to the top of the movable block 613. A micro switch is arranged on the top of the signal transmitter 614. A gear 1 615 is arranged inside the support seat 611 through a 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 inside of the support seat 611 is rotatably connected to a limit rod 617, and the limit rod 617 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, 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 inside of the mounting seat three 625 is rotatably connected to the clamping rod 626, the inside of the movable block 613 is rotatably 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, and 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 position where the goods are to be loaded and unloaded, and 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 seat 2 starts to operate, and according to the height of the cargo, the height of the connecting assembly 5 and the loading and unloading assembly 6 are adjusted to ensure that the loading and unloading assembly 6 can be accurately docked with the cargo pallet;

[0040] like Figure 5 , Figure 7 , Figure 8 , Fig. 9 and Fig.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 seat 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. In this process, the limit rod 617 that runs through the movable plate 612 and the movable block 613 plays a role in limiting the movement direction of the two and ensuring 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 a suitable initial clamping position;

[0041] At the same time, Figures 7 to 11 As shown, the worm 624 rotatably connected inside 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 with 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 driven to rotate through 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, when the loading and unloading component 6 moves , since 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 mesh with the worm wheel tooth groove at the bottom of the clamping rod 626, so that the clamping rod 626 rotates 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, and the position of the movable block 613 can be ensured to remain unchanged through friction).

[0042] The reset mechanism 63 can ensure that the gear 1 615 returns to the initial position after loading and unloading, 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 second mounting seat 57 on one side away from the connecting seat 2, and the interior of the second mounting seat 57 is rotatably connected to a connecting rod 55, and the end of the connecting rod 55 away from the second mounting seat 57 is rotatably connected to the first mounting seat 56, and an adjustment mechanism 51 is provided between the two first mounting seats 56, and the mounting plates 621 are fixedly connected to the first mounting seat 56, and the interior of the connecting seat 2 is symmetrically slidably connected to the connecting block 58, and the two connecting blocks 58 are fixedly connected to the same limiting plate 53 on the side away from the fixed seat 52, and the outer wall of the limiting plate 53 is fixed A servo motor 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 slidably connected with 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 with a screw rod 512. The movable seat 511 is internally fixedly connected with a connecting sleeve 513. The screw rod 512 and the connecting sleeve 513 form a spiral pair transmission. The end of the screw rod 512 close to the limit plate 53 is fixedly connected to the servo motor 2 54 through a coupling.

[0044] When the embodiment of the present invention is actually applied, the servo motor 2 54 is started according to the actual needs of the pallet and the goods. The servo motor 2 54 drives the screw rod 2 512 to rotate through the coupling. Since the screw rod 2 512 and the connecting sleeve 513 form a spiral pair transmission, the screw rod 2 512 can drive the movable seat 511 to move synchronously. When the movable seat 511 moves, the movable rod 514 slidably connected inside it drives the mounting seat 1 56 to move synchronously. The mounting seat 1 56 is rotatably connected to the mounting seat 2 57 through the connecting rod 55, and the mounting seat 2 57 is fixed to the fixed seat 52, so the movement of the mounting seat 1 56 will cause the movable rod 514 to move in the movable seat 511, and then the adaptive mechanism 61 fixed thereto adjusts the spacing to adapt to pallets and goods of different widths, thereby improving the 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, a screw rod 43 is symmetrically rotatably connected inside the connecting base 2, the tops of the two screw rods 43 are fixedly connected to a sprocket 44, a transmission chain 45 is transmission-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 applied, 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 the loading and unloading of pallets and goods of different heights, and 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 Fig.10 As shown, two groups of four protrusions 623 are symmetrically fixedly connected to the inner wall of the support seat 611, and the protrusions 623 are 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 movement stroke. The spring 2 627 can drive the clamping mechanism 62 to reset at the top of the adaptive mechanism 61, so as to release the clamping and facilitate the unloading of the pallet and materials.

[0049] like Fig.11 As shown, the reset mechanism 63 includes a mounting shaft 631 rotatably connected to the inside of the support seat 611 , a mounting frame 632 is symmetrically fixedly connected to the outer side of the support seat 611 , and a torsion spring 633 is fixedly connected between the mounting shaft 631 and the mounting frame 632 .

[0050] When the embodiment of the present invention is actually applied, 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 frame 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, the interior of the installation sleeve 622 is symmetrically provided with waist-shaped grooves, and the installation shaft 631 is slidably connected in the two waist-shaped grooves.

[0052] When the embodiment of the present invention is actually used, the waist-shaped groove provided on the installation sleeve 622 can realize the movement of the installation shaft 631 in the installation sleeve 622 .

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

[0054] In actual application of the embodiment of the present invention, the sliding connection between the guide ridge and the guide groove 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 article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "including one..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
