Description

Technical Field

[0001] This utility model belongs to the field of robotic arm technology and relates to a robotic arm. Background Technology

[0002] A robotic arm typically refers to the larger or main component of a programmable robotic arm that functions similarly to a human arm. This robotic arm can be a complete mechanical device or part of a more complex robot.

[0003] Robotic arms can perform various tasks, such as welding, grasping, and rotating objects. In logistics and warehousing, robotic arms can automatically handle and sort goods. In warehouses, it is often necessary to grasp various sheets and boxes. However, when the robotic arm grasps square boxes, it needs a mechanical gripper. But when grasping sheets, the mechanical gripper is difficult to use, requiring another robotic arm with a vacuum suction cup for adsorption and grasping. Often, two robotic arms are needed to work together. Two robotic arms not only mean that two sets of hardware systems need to be purchased and maintained, which greatly increases the hardware cost, but also require more space for installation and operation. This is a challenge for scenarios with limited warehouse space. Therefore, we have made improvements and proposed a robotic arm. Utility Model Content

[0004] The technical problem this invention aims to solve is that in warehouses, it is often necessary to grab various boards and material boxes. However, when a robotic arm grabs material boxes, it needs a mechanical claw. But when grabbing boards, the mechanical claw is difficult to use, so another robotic arm with a vacuum suction cup is needed for adsorption and grabbing. Often, two robotic arms are needed to work together. Two robotic arms not only mean that two sets of hardware systems need to be purchased and maintained, which greatly increases the hardware cost, but also require more space for installation and operation. This is a challenge for scenarios with limited warehouse space.

[0005] The present invention relates to a robotic arm, comprising a robotic arm body, a mounting base mounted on the top of the robotic arm body, a rotating spindle rotatably connected within the mounting base, a mounting plate mounted on the rotating spindle, a clamping assembly and an adsorption assembly mounted on the mounting plate, a driving assembly provided on one side of the mounting base, and an auxiliary lifting assembly connected to the bottom of the robotic arm body.

[0006] The clamping assembly includes a connecting frame, one end of which is connected to a mounting plate. A clamping frame is mounted on the end of the connecting frame away from the mounting plate. Two sliding plates are symmetrically slidably connected to the clamping frame. A first screw is threaded onto the sliding plate. A dual-axis motor is mounted on the clamping frame. The two output shafts of the dual-axis motor are connected to one end of the two first screws. The ends of the two first screws away from the dual-axis motor are rotatably connected to the clamping frame. A clamping plate is mounted on the sliding plate, and an anti-slip pad is mounted on the clamping plate.

[0007] Two sets of hydraulic support rods are installed at both ends of the clamping frame. The two hydraulic support rods form a set, and each set of hydraulic support rods is connected to the sliding plate by connecting plate bolts.

[0008] The adsorption assembly includes a fixed bracket, the bottom of which is mounted on a mounting plate, and a cylinder telescopic rod is mounted on the top of the fixed bracket, with a vacuum suction cup mounted on the top of the cylinder telescopic rod.

[0009] The drive assembly includes a first servo motor, one side of which is mounted on a mounting base. A worm gear is mounted on the output shaft of the first servo motor, a worm wheel is meshed on the worm gear, and a drive shaft is mounted on the worm wheel. The end of the drive shaft away from the worm wheel is connected to a rotating main shaft.

[0010] The auxiliary lifting assembly includes a robotic arm mounting base and two hydraulic telescopic rods. The top of the robotic arm mounting base is rotatably connected to the bottom of the robotic arm body. The robotic arm mounting base has multiple mounting holes. The two ends of the two hydraulic telescopic rods are hinged with hinge frames, which are respectively mounted on the robotic arm mounting base and the robotic arm body.

[0011] Compared with existing technologies, the advantages of this invention are: the robotic arm integrates a gripping component and an adsorption component, enabling it to simultaneously handle materials of different shapes and materials, such as material boxes and plates. Through simple operation and adjustment, switching between two different handling methods can be achieved, greatly improving the versatility and flexibility of the robotic arm.

[0012] The clamping assembly is driven by a dual-axis motor to rotate the first screw, which in turn drives the sliding plate and clamping plate to clamp and fix the material box to both sides. The addition of anti-slip pads further enhances the stability of the clamping. The adsorption assembly, through the cooperation of the cylinder telescopic rod and the vacuum suction cup, can firmly adsorb the material, ensuring that it will not fall off or slip during the handling process.

[0025] Example 1

[0026] like Figures 1-6 As shown, a robotic arm includes a robotic arm body 1, a mounting base 2 mounted on the top of the robotic arm body 1, a rotating spindle 3 rotatably connected within the mounting base 2, a mounting plate 4 mounted on the rotating spindle 3, and a clamping component and a suction component mounted on the mounting plate 4. A drive component is provided on one side of the mounting base 2, and an auxiliary lifting component is connected to the bottom of the robotic arm body 1. Through the rotation function of the drive component, the orientation of the clamping component and the suction component can be flexibly adjusted, allowing the same robotic arm body 1 to be suitable for handling materials of different shapes and sizes, such as square material boxes and plates. This adaptability improves the utilization rate and flexibility of the mechanical equipment and reduces the investment cost for enterprises for different material handling equipment. This robotic arm integrates clamping and suction components, and can simultaneously meet the needs of handling materials of different shapes and materials, such as material boxes and plates. Through simple operation and adjustment, switching between two different handling methods can be achieved, greatly improving the versatility and flexibility of the robotic arm.

[0027] The clamping assembly includes a connecting frame 8, one end of which is connected to the mounting plate 4. A clamping frame 9 is mounted on the end of the connecting frame 8 away from the mounting plate 4. Two sliding plates 10 are symmetrically slidably connected to the clamping frame 9. First screws 11 are threadedly connected to the sliding plates 10. A dual-axis motor 12 is mounted on the clamping frame 9. The output shafts of the dual-axis motor 12 are connected to one end of the two first screws 11. The ends of the two first screws 11 away from the dual-axis motor 12 are rotatably connected to the clamping frame 9. A clamping plate 13 is mounted on the sliding plate 10. An anti-slip pad 14 is mounted on the clamping plate 13. Two sets of hydraulic support rods 15 are mounted on both ends of the clamping frame 9. The two hydraulic support rods 15 form a set. Each set of hydraulic support rods 15 is bolted to the sliding plate 10 through a connecting plate 16. The adsorption assembly includes a fixed bracket 17. The bottom of the fixed bracket 17 is fitted with... Mounted on the mounting plate 4, a cylinder telescopic rod 18 is mounted on the top of the fixed bracket 17, and a vacuum suction cup 19 is mounted on the top of the cylinder telescopic rod 18. The drive assembly includes a first servo motor 6, one side of which is mounted on the mounting base 2. A worm gear 7 is mounted on the output shaft of the first servo motor 6, and a worm wheel 5 is meshed on the worm gear 7. A drive shaft 24 is mounted on the worm wheel 5, and the end of the drive shaft 24 away from the worm wheel 5 is connected to the rotating main shaft 3. The drive assembly is powered by the first servo motor 6. By using the meshing transmission of the worm gear 7 and the worm wheel 5, precise rotation control of the mounting plate 4 and the clamping and adsorption assemblies mounted on it can be achieved. This transmission method has self-locking properties, which can prevent reverse rotation caused by external load to a certain extent, thereby ensuring the stability and accuracy of the clamping and adsorption assemblies during the conversion process.

[0028] During operation, when clamping a square material box, the robotic arm body 1 drives the clamping assembly on the mounting base 2 to reach above the material box. The robotic arm body 1 then aligns the clamping assembly on the mounting base 2 with the material box. The robotic arm body 1 then moves the clamping plate 13 on the clamping assembly to place on both sides of the material box. The dual-axis motor 12 then drives the first screw 11 on its two output shafts to rotate. The first screw 11 drives the clamping plate 13 to clamp and fix on both sides of the material box through the sliding plate 10 that is threaded to it. The anti-slip pad 14 on the clamping plate 13 increases the friction between the clamping plate 13 and the material box clamping point, making the clamping more secure. After the clamping and fixing is completed, the robotic arm body 1 places the material box in the predetermined position.

[0029] When clamping the plate 13, the first servo motor 6 on the drive assembly drives the worm gear 7 to rotate on the mounting base 2. The worm gear 7 drives the worm wheel 5, which is meshed with it, to rotate. The worm wheel 5 drives the rotating main shaft 3 to rotate on the mounting base via the drive shaft 24, which in turn drives the mounting plate 4 connected to it to rotate 90 degrees clockwise. This causes the mounting plate 4 to align the adsorption assembly with the top of the robotic arm body 1 to adsorb the plate. The robotic arm body 1, through the mounting base 2 and the mounting plate 4, drives the vacuum suction cup 19 on the adsorption assembly to move towards the adsorption surface of the plate. The cylinder extension rod 18 causes the vacuum suction cup 19 to move towards the adsorption surface of the plate when it is aligned with the adsorption pad of the plate. The vacuum suction cup 19 then adsorbs the plate. The robotic arm body 1 drives the adsorption assembly to move the plate to a predetermined position. The drive assembly drives the clamping assembly and servo assembly on the mounting plate 4 to switch, thereby realizing the simultaneous use of the robotic arm for material storage and handling of material boxes and plates.

[0030] Example 2

[0031] like Figure 1 and Figure 6 As shown, the auxiliary lifting assembly includes a robotic arm mounting base 20 and two hydraulic telescopic rods 23. The top of the robotic arm mounting base 20 is rotatably connected to the bottom of the robotic arm body 1. Multiple mounting holes 21 are opened on the robotic arm mounting base 20. When installing the robotic arm, the entire robotic arm can be fixed by installing external bolts into the mounting holes 21 on the robotic arm mounting base 20. The two ends of the two hydraulic telescopic rods 23 are hinged with hinge frames 22. The hinge frames 22 at both ends of the two hydraulic telescopic rods 23 are respectively installed on the robotic arm mounting base 20 and the robotic arm body 1.

[0032] During operation, the hydraulic telescopic rod 23 moves with the lifting of the robotic arm body 1 via the hinged frames 22 at both ends, thus assisting in the lifting of the robotic arm body 1. With the assistance of the hydraulic telescopic rod 23, the robotic arm body 1 can more easily overcome gravity and other resistances, achieving more efficient lifting operations. The auxiliary role of the hydraulic telescopic rod 23 not only increases the lifting force but also enhances the stability of the entire robotic arm system by distributing the load and providing additional support points.
