Description

Technical Field

[0001] This utility model relates to the field of sorting robots, and more specifically, to a sorting robot loading mechanism. Background Technology

[0002] Common logistics sorting robots typically consist of a driven chassis and an adjustable gripper arm on top to grip and move packages. To adapt to the multi-shelf environment of logistics warehouses, these robots are generally small and space-saving, allowing them to enter relatively narrow spaces. However, the height of the sorting conveyor belt makes loading the robots difficult. Generally, extended gripper arms with height adjustment or a separate loading structure on the conveyor belt are used to assist the robot in loading. However, extended gripper arms increase the leverage arm, making the robot prone to tipping over during loading. A separate loading structure, on the other hand, can lead to inaccurate loading positions or omissions due to the large distance the packages are spread across the conveyor belt. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a sorting robot loading mechanism, which is set on both sides and above a sorting conveyor belt. It includes support frames placed on both sides of the sorting conveyor belt, a guide rail screw connected between the tops of the two support frames, and a loading tray set above the sorting conveyor belt. A lifting component is installed on the screw slide of the guide rail screw. Several guide grooves are evenly opened on the loading tray, and the guide grooves are arranged radially from the center of the loading tray. A loading clamping component extending to the bottom of the loading tray is set in the guide groove. Several sets of driving rods are evenly arranged on the upper surface of the loading tray. A rotatable turntable is set between the several sets of driving rods. The inner ends of the several sets of driving rods are movably connected to the turntable. A clamping driving component is set at the edge of the loading tray and movably connected to the outer end of any set of driving rods.

[0004] In a preferred embodiment, a servo motor for driving the lead screw of the guide rail is mounted on the support frame.

[0005] In a preferred embodiment, the feeding clamping component includes a guide rod disposed in a guide groove and a clamping block sleeved outside the guide rod. The outer wall of the clamping block is in contact with the inner wall of the guide groove, and a clamping plate extending to the bottom of the feeding tray is installed at the bottom of the clamping block.

[0006] In a preferred embodiment, the driving rod includes a driving rod located above the feeding tray, with vertically extending inserts at both ends of the driving rod. The ends of the two inserts are respectively fitted with a first bearing and a second bearing. The first bearing is installed on the feeding clamp, and the second bearing is installed at the edge of the turntable.

[0007] In a preferred embodiment, the clamping drive includes a servo push rod fixed at the edge of the loading tray, the output shaft of the servo push rod being parallel to the guide groove below the drive rod connected to the clamping drive, and the end of the output shaft of the servo push rod being fixedly connected to a plug rod inserted into the first bearing.

[0008] In a preferred embodiment, a third bearing is embedded in the center of the turntable, and a hanging rod is inserted into the third bearing. The bottom end of the hanging rod is fixed to the upper surface of the feeding tray, and the top end is connected to the lifting component.

[0009] The technical effects and advantages of this utility model are as follows:

[0010] 1. An independently set feeding mechanism is adopted, which is supported above the conveyor belt by a support frame. There is no need for the sorting robot to be equipped with an extended gripping arm, which avoids the risk of robot tipping caused by the extended lever arm and improves the stability of the feeding process.

[0011] 2. The guide rail screw and servo motor achieve precise lateral positioning, and the lifting component achieves height adaptation. With the help of radial guide grooves and synchronously driven clamping components, the express package is automatically centered and clamped, avoiding the positional deviation or omission problems that occur in the independent feeding structure, and improving the feeding accuracy.

[0012] 3. Multiple sets of feeding clamps are evenly distributed radially and synchronously contract towards the center to clamp the package. The clamping plate makes multiple contacts with the package and, together with the guide groove, limits the clamping block to prevent the package from shaking or falling off during clamping. This design is suitable for packages of different shapes and sizes. Attached Figure Description

Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0020] like Figure 1-5 The sorting robot loading mechanism shown is set on both sides and above the sorting conveyor belt 1. It includes support frames 2 on both sides of the sorting conveyor belt 1, guide rail screws 3 connected between the tops of the support frames 2 on both sides, and a loading tray 4 set above the sorting conveyor belt 1. A lifting component 13 is installed on the screw slide 31 of the guide rail screw 3. Several guide grooves 5 are evenly opened on the loading tray 4. The several guide grooves 5 are arranged radially from the center of the loading tray 4. A loading clamping component 6 extending to the bottom of the loading tray 4 is set in the guide grooves 5. Several sets of driving rods 7 are evenly arranged on the upper surface of the loading tray 4. A rotatable turntable 8 is set between the several sets of driving rods 7. The inner ends of the several sets of driving rods 7 are movably connected to the turntable 8. A clamping driving component 9 is set at the edge of the loading tray 4 and movably connected to the outer end of any set of driving rods 7.

[0021] Based on the above, the support frame 2 provides stable support for components such as the guide rail screw 3 and the feeding tray 4. The guide rail screw 3 and the screw slide 31 can drive the lifting component 13 and the feeding tray 4 below to move linearly along the guide rail screw 3. The lifting component 13 can extend and retract in the vertical direction, and drive the feeding tray 4 to lift and lower as a whole through the hanging rod 12. The radial guide groove 5 provides a precise movement trajectory for the feeding clamping component 6, limiting it to moving only in the direction close to or away from the center of the feeding tray 4. The inner end of the drive rod 7 is movably connected to the turntable 8, and the outer end is connected to the clamping drive component 9. When the clamping drive component 9 moves, it can drive the corresponding drive rod 7 to swing, thereby driving the turntable 8 to rotate. The turntable 8 synchronously drives all the evenly distributed drive rods 7 to move together, ultimately realizing the synchronous extension and retraction of all the loading clamping components 6, completing the clamping or releasing of the express package. The logistics sorting robot passes under the diversion conveyor belt from one side, and drives the loading tray 4 holding the express package to move to the logistics sorting robot through the guide rail screw 3 and screw slide 31. After that, the clamped express package is transferred to the logistics sorting robot, completing the loading work of the sorting robot.

[0022] Furthermore, the radial guide groove 5, in conjunction with multiple sets of feeding clamps 6, can clamp express packages from multiple directions, adapting to express packages of different shapes and sizes, and has a wide range of applications.

[0023] In one embodiment, a servo motor 10 is installed on the support frame 2 to drive the guide rail screw 3 to rotate. The servo motor 10 drives the guide rail screw 3 and the screw slide 31 to move, thereby driving the lifting component 13, the hanging rod 12 and the loading tray 4 to move synchronously in the lateral direction. By controlling the forward and reverse rotation and the rotation angle of the servo motor 10, the lateral position of the loading tray 4 can be precisely adjusted.

[0024] In one embodiment, the feeding clamp 6 includes a guide rod 61 disposed in the guide groove 5 and a clamping block 62 sleeved outside the guide rod 61. The outer wall of the clamping block 62 is in contact with the inner wall of the guide groove 5, and a clamping plate 63 extending to the bottom of the feeding tray 4 is installed at the bottom of the clamping block 62.

[0025] Based on the above, the clamping block 62 is sleeved on the outside of the guide rod 61, and its outer wall is tightly fitted with the inner wall of the guide groove 5, limiting the clamping block 62 to move only along the length direction of the guide groove 5. The clamping plate 63 at the bottom of the clamping block 62 extends horizontally. When the clamping block 62 retracts towards the center, the clamping plate 63 approaches from all sides of the express package, contacts the surface of the express package and applies clamping force. Since the contact area of ​​the clamping plate 63 is large, it can disperse the clamping force and avoid damage to the express package.

[0026] In one embodiment, the drive rod 7 includes a drive rod 71 located above the loading tray 4. Both ends of the drive rod 71 are provided with vertically extending insert rods 72. The ends of the two insert rods 72 are respectively fitted with a first bearing 73 and a second bearing 74. The first bearing 73 is installed on the clamping block 62 of the loading clamping member 6, and the second bearing 74 is installed at the edge of the turntable 8.

[0027] Based on the above, the inserts 72 at both ends of the drive rod 71 are fixedly connected to the inner rings of the first bearing 73 and the second bearing 74, respectively. The outer ring of the first bearing 73 is fixed on the clamping block 62, and the outer ring of the second bearing 74 is fixed at the edge of the turntable 8. When the clamping drive member 9 pushes the outer end of one set of drive rods 71, the drive rod 71 swings around the second bearing 74. At the same time, it pushes the clamping block 62 to move along the guide groove 5 through the first bearing 73. The swing of the drive rod 71 will drive the turntable 8 to rotate. The turntable 8 synchronously drives all other drive rods 7 to swing, thereby realizing the synchronous extension and retraction of all clamping blocks 62.

[0028] Furthermore, all drive rods 7 are linked through turntable 8 to ensure that all feeding clamps 6 move synchronously and the clamping force is uniform, preventing express packages from tilting or falling off due to uneven force; the structure is compact, occupies little space above the feeding tray 4, and does not affect the operation of other components.

[0029] In one embodiment, the clamping drive 9 includes a servo push rod 91 fixed at the edge of the loading tray 4. The output shaft of the servo push rod 91 is parallel to the guide groove 5 below the drive rod 7 connected to the clamping drive 9. The end of the output shaft of the servo push rod 91 is fixedly connected to the insert rod 72 inserted into the first bearing 73.

[0030] Based on the above, the output shaft end of the servo push rod 91 is fixedly connected to the insertion rod 72 at the outer end of the drive rod 71. After startup, the output shaft of the servo push rod 91 extends and retracts, directly pushing the insertion rod 72, which in turn drives the drive rod 71 to swing. The inner end of the drive rod 71 drives the turntable 8 to rotate through the second bearing 74. The turntable 8 links all the drive rods 7, ultimately realizing that all the clamping blocks 62 synchronously retract towards the center or expand outward, completing the clamping or releasing action.

[0031] In one embodiment, a third bearing 11 is embedded in the middle of the turntable 8, and a hanging rod 12 is inserted into the third bearing 11. The bottom end of the hanging rod 12 is fixed to the upper surface of the feeding tray 4 and the top end is connected to the lifting component 13.

[0032] Based on the above, the outer ring of the third bearing 11 is embedded in the middle of the turntable 8, and the inner ring is tightly fitted with the hanging rod 12. The bottom end of the hanging rod 12 is fixed to the upper surface of the feeding tray 4, and the top end is connected to the output end of the lifting component 13. The third bearing 11 not only limits the axial position of the turntable 8 to prevent it from shifting up and down, but also allows the turntable 8 to rotate flexibly around the hanging rod 12 without affecting the linkage action of the drive rod 7. When the lifting component 13 extends or retracts, it drives the feeding tray 4 to rise and fall vertically through the hanging rod 12. At this time, the inner ring of the third bearing 11 rises and falls with the hanging rod 12, while the outer ring remains relatively stationary with the turntable 8, ensuring that the lifting action and the rotation action of the turntable 8 do not interfere with each other.

[0033] Based on the above, this practical feeding mechanism is independently supported above the sorting conveyor belt 1 by the support frame 2, eliminating the need for the sorting robot to be equipped with an extended gripping arm, avoiding the risk of the robot tipping over due to the extended lever arm, and improving the stability of the feeding process.

[0034] The guide rail screw 3 and servo motor 10 achieve precise lateral positioning, the lifting component 13 achieves height adaptation, and together with the radial guide groove 5 and the synchronously driven feeding clamp 6, the express package is automatically centered and clamped, avoiding the positional deviation or omission problem that occurs in the separate feeding structure, and the feeding accuracy is significantly improved.

[0035] Multiple sets of feeding clamping parts 6 are evenly distributed radially and synchronously contract towards the center to clamp. The clamping plate 63 makes multiple contacts with the express delivery, and the guide groove 5 limits the clamping block 62 to prevent the express delivery from shaking or falling off during the clamping process. It is suitable for express delivery parts of different shapes and sizes.

[0036] Both the lateral position and the lifting height are adjustable, which can accommodate sorting robots and sorting conveyors of different heights, and can also be compatible with express parcels of different specifications, without the need for modification to specific equipment or products.

[0037] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
