Description

Technical Field

[0001] This utility model belongs to the field of logistics sorting technology, and specifically relates to a logistics sorting robot. Background Technology

[0002] Logistics sorting robots are intelligent devices specifically designed for automated logistics warehousing and distribution centers, primarily used for the rapid and accurate sorting and handling of packages and goods. Existing logistics sorting robots consist of robotic arms and drive systems. These robotic arms are typically optimized for items of fixed size, shape, and material. Therefore, existing robotic arms can usually only grasp one type of logistics package. For example, a robotic arm with suction cups can typically only grasp box-shaped packages. However, when grasping box-shaped packages, existing suction cup robotic arms may not always be able to pick up the center of the package, potentially causing the package to wobble and fall. Furthermore, when grasping packages of small, irregularly shaped industrial parts, suction cup robotic arms may not be able to effectively grip the package, leading to a decrease in logistics package sorting efficiency. Therefore, a new structure is proposed to address these issues. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a logistics sorting robot to solve the problems mentioned in the background technology.

[0004] This utility model is achieved through the following technical solution: a logistics sorting robot, including: a rotating component and a locking component, wherein the rotating component is installed on the top of the support base, the rotating component includes a rotating base for placing a turntable, and a number of sets of balls are embedded in the annular area away from the center of the rotating base.

[0005] A locking component is embedded in the front side of the lower inner surface of the rotating base. The locking component includes a locking rod. A suction cup robotic arm is installed on the right side of the top of the turntable, and a gripper robotic arm is installed on the left side of the top of the turntable.

[0006] In a preferred embodiment, the bottom of the support base is bonded with a rubber layer, and the bottom of the rubber layer has a herringbone anti-slip pattern. The top of the support base is welded to the center of the bottom of the rotating base.

[0007] The right side of the support base is equipped with a conveyor belt for transporting logistics packages. A barcode scanner is installed on the side of the rotating base near the conveyor belt. The rubber layer at the bottom of the support base and the anti-slip texture at the bottom of the rubber layer can increase the friction between the support base and the ground, thereby making the support base more stable.

[0008] In a preferred embodiment, the radius and depth of the inner side of the rotating base match the radius and thickness of the turntable. A drive motor is vertically mounted below the inner side of the rotating base, and a transmission shaft is mounted on the top of the drive motor via a coupling.

[0009] In a preferred embodiment, a shaft groove is provided at the center of the bottom of the turntable, and the top of the drive shaft passes through the center of the inner lower surface of the rotating base and is connected and fixed to the shaft groove.

[0010] The turntable has an installation groove on the left and right sides of its top, and the rotating base has a sliding groove in the annular area away from the center. The radius of the sliding groove matches the radius of the area enclosed by several sets of balls.

[0011] In a preferred embodiment, a suction cup robotic arm is installed inside the mounting slot on the right. The suction cup robotic arm includes a drive mechanism, a transmission arm, and a suction cup assembly. A gripper robotic arm is installed inside the mounting slot on the left. The gripper robotic arm includes a drive mechanism, a transmission arm, and a gripper assembly.

[0012] In a preferred embodiment, a locking groove is provided on the front side of the shaft groove, the radius of the locking groove is matched with the radius of the locking rod, and the locking rod extends upward through the lower inner surface of the rotating base.

[0013] In a preferred embodiment, the bottom of the locking rod is recessed upward to form a docking cavity. A return spring is installed on the upper inner side of the docking cavity. The top of the return spring is fixed to the upper inner surface of the docking cavity. A magnetic ring is fixed on the lower outer side of the locking rod. An infrared sensor is embedded in the top of the locking rod.

[0014] In a preferred embodiment, the locking assembly further includes a docking base, which includes an electromagnetic plate and a docking rod, the docking rod being located at the top center of the electromagnetic plate.

[0015] In a preferred embodiment, the radius and length of the docking rod are matched with its height and the radius and depth of the inner side of the docking cavity. The top of the docking rod is fixed to the bottom of the reset spring. The magnetic ring and the electromagnetic plate have the same radius and opposite poles.

[0016] After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. By setting a rotating component, a suction cup robotic arm, and a gripper robotic arm, the rotating component includes a rotating base and a turntable. The turntable is located inside the rotating base and is driven to rotate by a drive motor installed below the rotating base. An installation slot is opened on the left and right sides of the top of the turntable. The gripper robotic arm is installed in the left installation slot, and the suction cup robotic arm is installed in the right installation slot. In actual use, the conveyor belt on the right side of the support base slowly transports the logistics packages from front to back. At this time, the barcode scanner installed on the right side of the rotating base scans and identifies the information of the logistics packages. When the logistics package is heavy, the turntable rotates clockwise to rotate the gripper robotic arm to the side closer to the conveyor belt, thereby gripping and sorting the logistics package. Similarly, when the package is light, the suction cup robotic arm rotates to the side closer to the conveyor belt under the drive of the turntable to grip and sort the lighter package. Therefore, the final effect is to significantly improve the flexibility of the logistics sorting robot, save the time spent changing robotic arms, and improve sorting efficiency.

[0017] 2. By setting up sliding grooves, ball bearings, and locking components, several sets of ball bearings are embedded in an annular area on the lower inner surface of the rotating base away from the center. In actual use, the tops of the ball bearings are located inside the sliding grooves, and the locking lever is in a retracted state. When the turntable rotates, the ball bearings roll along the sliding grooves, thereby reducing the friction between the bottom of the turntable and the lower inner surface of the rotating base. This makes the turntable rotation more stable and effortless. After the turntable has finished rotating, the infrared sensor at the top of the locking lever detects the presence of the locking groove, thereby disconnecting the power to the electromagnetic plate. The electromagnetic plate loses its magnetism and disengages from the magnetic ring. The return spring rebounds and pushes the locking lever upward into the locking groove, thus locking the turntable. The final effect is to reduce the friction when the turntable rotates, making the turntable rotation more stable and effortless. The locking component can fix the position of the turntable, thereby enabling the suction cup robotic arm and gripper robotic arm to be positioned at the prepared sorting position, facilitating the sorting work of the suction cup robotic arm and gripper robotic arm.

Obviously, the described embodiments are only one aspect of the present utility model, and not all aspects. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0027] Please see Figures 1 to 4 A logistics sorting robot includes a rotating component 200 and a locking component 300. The rotating component 200 is mounted on the top of a support base 100. The rotating component 200 includes a rotating base 210 for placing a turntable 220. Several sets of balls 211 are embedded in an annular area away from the center of the rotating base 210.

[0028] A locking component 300 is embedded in the front side of the lower inner surface of the rotating base 210. The locking component 300 includes a locking rod 310. A suction cup robotic arm 110 is installed on the top right side of the turntable 220, and a gripper robotic arm 120 is installed on the top left side of the turntable 220.

[0029] The bottom of the support base 100 is bonded with a rubber layer, and the bottom of the rubber layer has a herringbone anti-slip pattern. The top of the support base 100 is welded to the center of the bottom of the rotating base 210.

[0030] The support base 100 has a conveyor belt for transporting logistics packages on its right side. A barcode scanner is installed on the side of the rotating base 210 near the conveyor belt. The rubber layer at the bottom of the support base 100 and the anti-slip texture at the bottom of the rubber layer can increase the friction between the support base 100 and the ground, thereby making the support base 100 more stable.

[0031] The radius and depth of the inner side of the rotating base 210 match the radius and thickness of the turntable 220. A drive motor is vertically mounted on the lower inner side of the rotating base 210, and a transmission shaft 212 is mounted on the top of the drive motor via a coupling.

[0032] A shaft groove 223 is provided at the center of the bottom of the turntable 220, and the top of the drive shaft 212 passes through the center of the inner lower surface of the rotating base 210 and is connected and fixed to the shaft groove 223.

[0033] The turntable 220 has an installation groove 221 on the left and right sides of the top, and the rotating base 210 has a sliding groove 222 in the annular area away from the center at the bottom. The radius of the sliding groove 222 matches the radius of the area enclosed by several sets of balls 211.

[0034] The right mounting slot 221 houses a suction cup robotic arm 110, which includes a drive mechanism, a transmission arm, and a suction cup assembly. The left mounting slot 221 houses a gripper robotic arm 120, which includes a drive mechanism, a transmission arm, and a gripper assembly.

[0035] A locking groove 224 is provided on the front side of the shaft groove 223. The radius of the locking groove 224 matches the radius of the locking rod 310. The locking rod 310 extends upward through the lower inner surface of the rotating base 210.

[0036] The bottom of the locking rod 310 is recessed upward to form a docking cavity. A return spring 311 is installed on the upper inner side of the docking cavity. The top of the return spring 311 is fixed to the upper inner surface of the docking cavity. A magnetic ring 312 is fixed on the lower outer side of the locking rod 310. An infrared sensor is embedded in the top of the locking rod 310.

[0037] The locking assembly 300 also includes a docking base 320, which includes an electromagnetic plate 321 and a docking rod, with the docking rod located at the top center of the electromagnetic plate 321.

[0038] The radius and length of the docking rod are matched with its height and the radius and depth of the docking cavity. The top of the docking rod is fixed to the bottom of the return spring 311. The magnetic ring 312 and the electromagnetic plate 321 have the same radius and opposite poles.

[0039] Example 1: Please refer to Figure 1 and Figure 2 In actual use, a rotating assembly 200 is welded to the top of the support base 100. The rotating assembly 200 includes a turntable 220 and a rotating base 210. A drive motor is vertically installed inside the support base 100 below the rotating base 210. The top output end of the drive motor is connected to a transmission shaft 212 via a coupling. The top of the transmission shaft 212 extends upward through the lower inner surface of the rotating base 210 and into the inner side of the rotating base 210. The turntable 220 is installed inside the rotating base 210. A shaft groove 223 is provided at the center of the bottom of the turntable 220 to mate with the transmission shaft 212. Therefore, the rotation of the drive motor can drive the turntable 220 to rotate. A mounting groove 221 is provided on the left and right sides of the top of the turntable 220, and a mounting groove 223 is provided on the left side. A gripper robotic arm 120 is installed above the support base 100. A suction cup robotic arm 110 is installed above the mounting slot 221 on the right side. The suction cup robotic arm 110 includes a drive mechanism, a transmission arm, and a suction cup assembly. The gripper robotic arm 120 includes a drive mechanism, a transmission arm, and a gripper assembly. (The drive motor, suction cup robotic arm 110, and gripper robotic arm 120 are all existing technologies, and their internal structures and working principles will not be described in detail here.) A conveyor belt for conveying logistics packages is installed on the right side of the support base 100. The logistics packages on the conveyor belt move from back to front. A barcode scanner is installed on the side of the rotating component 200 near the conveyor belt to identify the weight information in the package so that the suction cup robotic arm 110 and the gripper robotic arm 120 can be used selectively.

[0040] In actual use, the conveyor belt slowly transports several groups of sorted logistics packages from back to front. At this time, the barcode scanner scans and identifies the packages (the barcode scanner is existing technology, and its internal structure and working principle will not be described in detail here). When a heavier package is identified, the drive motor starts, driving the turntable 220 to rotate clockwise via the transmission shaft 212, rotating the gripper arm 120 to the side closer to the conveyor belt. Then, the gripper arm 120 clamps the identified package. After clamping, the drive motor rotates in the opposite direction, rotating the gripper arm 120 to the side away from the conveyor belt. The support base 100 has two separate package sorting areas on the side away from the conveyor belt: Package Sorting Area 1 and Package Sorting Area 2. After the robotic arm 120 places the package in the first package sorting area, it completes one package sorting operation. Similarly, when a lighter package is detected, the suction cup robotic arm 110 picks up the lighter package and transports it to the second package sorting area for placement. It should be noted that the conveyor belt's conveying speed is much lower than the speed at which the suction cup robotic arm 110 and the gripper robotic arm 120 complete one sorting operation. Also, the side of the package with the identification code on the conveyor belt always faces the barcode scanner. Therefore, by maintaining the slow movement of the conveyor belt, continuous package sorting can be carried out by the suction cup robotic arm 110 and the gripper robotic arm 120. The final effect is to significantly improve the flexibility of the logistics sorting robot, save the time spent changing robotic arms, and improve sorting efficiency.

[0041] Example 2: Please refer to Figures 2 to 4 A sliding groove 222 is provided in the annular area away from the center of the bottom of the turntable 220. A locking groove 224 is provided on the front side of the shaft groove 223 at the bottom of the turntable 220. Several sets of balls 211 are equidistantly embedded in the annular area away from the center on the inner lower surface of the rotating base 210. The radius of the annular area formed by the several sets of balls 211 matches the radius of the sliding groove 222, and the tops of the several sets of balls 211 are respectively located inside the sliding groove 222. A locking component 300 is embedded in the front side of the center of the inner lower surface of the rotating base 210. The locking component 300 includes a locking rod 310 and a docking base 320. The bottom of the locking rod 310 An upwardly recessed groove forms a docking slot. A return spring 311 is installed on the upper inner side of the docking slot. The top of the return spring 311 is fixed to the upper inner surface of the docking cavity. A magnetic ring 312 is fixed to the outer side below the locking rod 310. An infrared sensor for identifying the locking slot 224 is embedded in the top of the locking rod 310. The docking base 320 includes an electromagnetic plate 321 and a docking rod. The docking rod is located at the top center of the electromagnetic plate 321. The radius and height of the docking rod match the radius and depth of the inner side of the docking cavity. The top of the docking rod is fixed to the bottom of the return spring 311. The magnetic ring 312 has the same radius as the electromagnetic plate 321 and opposite poles.

[0042] In actual use, when the turntable 220 rotates, the electromagnetic plate 321 in the locking assembly 300 is energized and attracted and fixed by the magnetic ring 312. At this time, the return spring 311 is in a compressed and stored state, and the locking rod 310 is in a retracted state. Several sets of balls 211 roll and rub along the sliding groove 222. Therefore, the sliding friction between the bottom of the turntable 220 and the inner lower surface of the rotating base 210 can be converted into rolling friction of several sets of balls 211 through the rolling of several sets of balls 211, which can significantly reduce the frictional resistance of the turntable 220. Therefore, the rotation of the turntable 220 can be made more effortless and stable. When the turntable 220 rotates any one of the suction cup robotic arm 110 and the gripper robotic arm 120 close to the transmission... At the moment the conveyor belt is fed, the locking slot 224 is identified by the infrared sensor embedded in the top of the locking rod 310 (the infrared sensor is existing technology, and its internal structure and working principle will not be described here). The electromagnetic plate 321 loses power and magnetism and disengages from the magnetic ring 312. At this time, the return spring 311 rebounds and resets, pushing the locking rod 310 upward into the locking slot 224, thereby completing the locking of the turntable 220. Therefore, the final effect is to make the turntable 220 rotate more stably and with less effort. The position of the turntable 220 can be fixed by the locking component 300, which in turn enables the suction cup robotic arm 110 and the gripper robotic arm 120 to be positioned at the prepared sorting position, making it convenient for the suction cup robotic arm 110 and the gripper robotic arm 120 to perform sorting work.
