Description

Technical Field

[0001] This utility model relates to the field of robotics, specifically to a robotic arm for handling robots. Background Technology

[0002] With the rapid development of industrial automation technology, material handling robots have been widely used in logistics warehousing, production line material transfer, and other fields. As the core actuator of a material handling robot, the performance of its gripping components directly affects handling efficiency and cargo safety. Traditional material handling robots mostly use rigid grippers or vacuum suction cups as gripping devices, which have the following significant drawbacks in practical applications:

[0003] Rigid clamping can easily damage goods: Existing grippers are mostly made of hard metal or plastic, and come into direct contact with the surface of the goods during clamping. When handling fragile items (such as glassware and precision electronic components) or goods with easily damaged surfaces (such as polished parts and packaging boxes), the concentrated clamping force can easily cause scratches, indentations, or even breakage. Especially for irregularly shaped goods, rigid grippers are difficult to self-adapt to wrapping, have poor clamping stability, and are prone to causing the goods to shake or slip during handling.

[0004] Lack of auxiliary limiting structure: Traditional clamping devices lack multi-dimensional limiting design for goods. In the initial stage of handling, when the grippers are not fully closed, the goods are only partially supported by the grippers, making them unstable and prone to tipping over. Although some equipment has added fixed barriers, they cannot accommodate goods of different sizes, and there is a risk of rigid collision between the barriers and the goods.

[0005] Insufficient maintenance convenience: The limiting structures in the clamping components are mostly welded or integrally molded designs, requiring complete disassembly to replace damaged parts, which is complex and time-consuming. For example, in the prior art, if the limiting mesh is damaged, the entire clamping frame must be removed for replacement, which seriously affects equipment maintenance efficiency and increases downtime costs. Utility Model Content

[0006] The purpose of this invention is to provide a robotic arm for handling robots to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A robotic arm for handling includes a robotic arm, a connecting seat, and a handling clamping assembly. One end of the robotic arm is provided with the handling clamping assembly via the connecting seat. The handling clamping assembly includes a clamping frame, and a clamping drive unit is provided at the top of the clamping frame. The clamping drive unit is used to drive the clamping frame to perform clamping work.

[0009] The clamping frame is movably connected to a limiting mesh docking frame on its side. An elastic limiting mesh is fixedly connected to the inner wall of the limiting mesh docking frame. A docking plate is fixedly connected to the side of the limiting mesh docking frame near the top. A limiting hanging plate is fixedly connected to the side of the clamping frame near the top. The inner wall of the docking plate engages with the outer wall of the limiting hanging plate. A hanging plate slot for docking with the limiting hanging plate is opened at the top of the limiting mesh docking frame. The outer wall of the limiting hanging plate is movably connected to the inner wall of the hanging plate slot. An L-shaped receiving plate is fixedly connected to the side of the clamping frame near the bottom. The inner wall of the L-shaped receiving plate is movably inserted into the bottom of the limiting mesh docking frame.

[0010] A further improvement of this utility model is that: a threaded hole is provided on the side of the L-shaped receiving plate away from the clamping frame, and a bolt with one end penetrating through the limiting mesh and connecting frame is threaded to the inner wall of the threaded hole.

[0011] A further improvement of this utility model is that: a reinforcing elastic strip is fixedly connected to the outer wall of the elastic limiting net, and the two ends of the reinforcing elastic strip are fixedly connected to the inner wall of the limiting net docking frame.

[0012] A further improvement of this utility model is that a shovel plate is fixedly connected to the bottom surface of the clamping frame.

[0013] A further improvement of the present invention is that the clamping drive unit includes a slider, which is fixedly connected to the top of the clamping frame.

[0014] A further improvement of this utility model is that: a bidirectional cylinder is fixedly connected to one side of the slider, a mounting frame is slidably connected to the outer wall of the slider, and the bidirectional cylinder is fixedly connected to the inner wall of the mounting frame through a mounting block.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. This utility model provides a robotic arm for a handling robot. During the handling process, the shovel plate first contacts the bottom surface of the goods, providing stable support and preventing the goods from shaking or tipping over in the initial stage of handling. Subsequently, the elastic limiting net, along with the limiting net docking frame, simultaneously contacts the surface of the goods. When the clamping frame closes under the drive of a bidirectional cylinder, the elastic limiting net undergoes elastic deformation, tightly wrapping the goods. Compared with traditional rigid clamping, this elastic wrapping method does not cause scratches, squeezing, or other damage to the surface of the goods. It is especially suitable for handling fragile or easily damaged goods, greatly improving the stability and safety of the goods during handling and effectively reducing the damage rate.

[0017] 2. This utility model provides a robotic arm for a handling robot. The limiting mesh docking frame adopts a unique three-dimensional positioning structure. Its top engages with the limiting mounting plate via a mounting plate slot to achieve precise vertical positioning; the bottom relies on an L-shaped receiving plate for horizontal support; and the sides utilize a locking structure between the docking plate and the limiting mounting plate to prevent detachment during use. Furthermore, it is fixed by bolts passing through the threaded holes of the L-shaped receiving plate. When maintenance is required, the operator only needs to loosen the bolts to easily disassemble the entire limiting mesh docking frame. This design significantly shortens maintenance time, reduces maintenance difficulty, improves the overall maintenance efficiency of the handling robot arm, reduces downtime caused by maintenance, and enhances equipment utilization efficiency.

[0025] The present invention will be further described in detail below with reference to embodiments:

[0026] Example 1

[0027] like Figure 1-5 As shown, this utility model provides a robotic arm for handling robots, including a robotic arm 1, a connecting seat 2, and a handling clamping assembly 3. One end of the robotic arm 1 is provided with the handling clamping assembly 3 through the connecting seat 2. The handling clamping assembly 3 includes a clamping frame 6, and a clamping drive unit is provided at the top of the clamping frame 6. The clamping drive unit is used to drive the clamping frame 6 to perform clamping work.

[0028] The side of the clamping frame 6 is movably connected to the limiting net docking frame 13. The inner wall of the limiting net docking frame 13 is fixedly connected to the elastic limiting net 8. The side of the limiting net docking frame 13 near the top is fixedly connected to the docking plate 12. The side of the clamping frame 6 near the top is fixedly connected to the limiting hanging plate 11. The inner wall of the docking plate 12 is engaged with the outer wall of the limiting hanging plate 11. The top of the limiting net docking frame 13 is provided with a hanging plate slot 14 for docking with the limiting hanging plate 11. The outer wall of the limiting hanging plate 11 is movably connected to the inner wall of the hanging plate slot 14. The side of the clamping frame 6 near the bottom is fixedly connected to the L-shaped receiving plate 15. The inner wall of the L-shaped receiving plate 15 is movably inserted into the bottom of the limiting net docking frame 13.

[0029] Example 2

[0030] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the L-shaped receiving plate 15 has a threaded hole 16 on the side away from the clamping frame 6, and the inner wall of the threaded hole 16 is threaded with a bolt 17 that penetrates through the limiting net connecting frame 13.

[0031] The outer wall of the elastic limiting net 8 is fixedly connected with a reinforcing elastic strip 10, and the two ends of the reinforcing elastic strip 10 are fixedly connected to the inner wall of the limiting net docking frame 13.

[0032] A shovel plate 7 is fixedly connected to the bottom surface of the clamping frame 6.

[0033] The clamping drive unit includes a slider 9, which is fixedly connected to the top of the clamping frame 6.

[0034] A bidirectional cylinder 5 is fixedly connected to one side of the slider 9, and a mounting frame 4 is slidably connected to the outer wall of the slider 9. The bidirectional cylinder 5 is fixedly connected to the inner wall of the mounting frame 4 through a mounting block.

[0035] The working principle of the robotic arm of this handling robot will be explained in detail below.

[0036] like Figure 1-5As shown, the robotic arm moves the handling and clamping assembly 3 to the outside of the target goods via the connecting seat 2. The bidirectional cylinder 5 of the clamping drive unit drives the slider 9 to move the clamping frame 6 to perform clamping work. The shovel plate 7 first contacts the bottom surface of the goods to form support. The elastic limiting net 8 contacts the surface of the goods simultaneously with the limiting net docking frame 13. The bidirectional cylinder continues to apply pressure to close the clamping frame 6. The elastic limiting net 8 generates elastic deformation to wrap the goods, and the robotic arm 1 lifts to complete the handling.

[0037] The limiting mesh docking frame 13 adopts a three-dimensional positioning structure. The top is vertically positioned with the limiting mounting plate 11 via the mounting plate slot 14. The bottom is horizontally supported by an L-shaped receiving plate 15.

[0038] The side is secured by a snap-fit ​​structure between the mating plate 12 and the limiting hanging plate 11 to prevent detachment. Bolts 17 pass through the threaded holes 16 of the L-shaped receiving plate 15 for quick fixation. During maintenance, the limiting mesh mating frame 13 can be completely disassembled simply by loosening the bolts 17.

[0039] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
