Description

Technical Field

[0001] This utility model relates to a robotic arm for loading and unloading columnar materials, belonging to the technical field of robotic arms for handling columnar materials. Background Technology

[0002] In manufacturers of shafts or columns, the shafts need to be transported or transferred after production. Small and medium-sized enterprises typically use manual handling to save costs. However, manual handling poses significant safety hazards and is inefficient, impacting the overall profitability of the business.

[0003] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0004] This utility model addresses the shortcomings of the prior art by providing a robotic arm for loading and unloading columnar materials. It can completely replace manual labor in loading and unloading columnar materials, and can simultaneously pick up columnar materials and material trays. It can also automatically pick up and place materials during both destacking and stacking.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: A robotic arm for loading and unloading columnar materials includes an aluminum alloy frame, with a set of suction cups symmetrically arranged on the lower sides of both sides of the aluminum alloy frame; A parallel clamping cylinder is installed between two sets of suction cups on the aluminum alloy frame. A fixed block is installed on each of the two sliding blocks of the parallel clamping cylinder. A gripper is installed at the lower end of each fixed block. The side of the lower end of the gripper is provided with a V-shaped groove. The V-shaped grooves of the grippers on the two fixed blocks are arranged facing each other.

[0006] Furthermore, two grippers are fixedly installed at the lower end of each fixing block.

[0007] Furthermore, a sliding rod cylinder is provided in the middle of the aluminum alloy frame. The sliding rod cylinder is mounted on the aluminum alloy frame through a first mounting bracket, and the sliding rod of the sliding rod cylinder is set vertically. The parallel clamping cylinder is fixed to the sliding component of the sliding rod cylinder through a second mounting bracket.

[0008] Furthermore, the sliding direction of the sliding block of the parallel clamping cylinder is arranged along the transverse direction of the aluminum alloy frame.

[0009] Furthermore, the sliding direction of the sliding block of the parallel clamping cylinder is arranged along the longitudinal direction of the aluminum alloy frame.

[0010] Furthermore, a strip-shaped suction cup mounting plate is installed at the lower end of both sides of the aluminum alloy frame, and multiple suction cups are installed on the suction cup mounting plate along its length.

[0011] Furthermore, a barcode scanner is installed at the upper part of the aluminum alloy frame.

[0012] Furthermore, it also includes a multi-axis robot, with a mounting plate fixed to the top of the aluminum alloy frame, the end of the multi-axis robot arm fixed to the mounting plate, and the lower end of the multi-axis robot mounted on a support column.

[0013] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: The sliding cylinder drives the parallel clamping cylinder downwards, the grippers clamp the columnar material, and after moving the columnar material to the designated position, all the columnar material on the material tray is removed. The sliding cylinder then drives the parallel clamping cylinder upwards. At this time, the lower end of the suction cup is higher than the lower end of the grippers, and the suction cup holds the material tray and transfers it. This can completely replace manual loading and unloading of columnar materials, and can simultaneously pick up columnar materials and material trays. Automatic material handling can be achieved during both destacking and stacking.

[0014] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0017] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0018] like Figure 1-5 As shown, this utility model provides a robotic arm for loading and unloading columnar materials, including an aluminum alloy frame 4, with a set of suction cups 6 symmetrically arranged on the lower sides of both sides of the aluminum alloy frame 4; A parallel clamping cylinder 11 is installed between two sets of suction cups 6 on the aluminum alloy frame 4. A fixing block 12 is installed on each of the two sliding blocks of the parallel clamping cylinder 11. A gripper 13 is installed at the lower end of each fixing block 12. A V-shaped groove 14 is provided on the side of the lower end of the gripper 13. The V-shaped grooves 14 of the grippers 13 on the two fixing blocks 12 are arranged facing each other.

[0019] Two grippers 13 are fixedly installed at the lower end of each fixed block 12. Each sliding block of the parallel clamping cylinder 11 drives the two grippers 13 to move. When the grippers 13 on both sides are closed, the cylindrical material is clamped in the V-shaped groove 14.

[0020] A sliding cylinder 9 is provided in the middle of the aluminum alloy frame 4. The sliding cylinder 9 is mounted on the aluminum alloy frame 4 through a first mounting bracket 8, and the sliding rod of the sliding cylinder 9 is set vertically. The parallel clamping cylinder 11 is fixed to the sliding part of the sliding cylinder 9 through a second mounting bracket 10.

[0021] The sliding direction of the sliding block of the parallel clamping cylinder 11 is set along the transverse direction of the aluminum alloy frame 4.

[0022] In other embodiments, the sliding direction of the sliding block of the parallel clamping cylinder 11 is arranged along the longitudinal direction of the aluminum alloy frame 4.

[0023] A strip-shaped suction cup mounting plate 5 is installed at the lower ends of both sides of the aluminum alloy frame 4, and multiple suction cups 6 are installed on the suction cup mounting plate 5 along its length.

[0024] A barcode scanner 7 is located near the top of the aluminum alloy frame 4. The surface of the cylindrical material is marked with a code, with the marked side facing upwards. When the robotic arm moves over the cylindrical material, it scans the material and transmits the material's code information to the workshop's MES system for easy tracking of production materials.

[0025] This utility model also includes a multi-axis robot 2, with an installation plate 3 fixed to the top of the aluminum alloy frame 4, the end of the robotic arm of the multi-axis robot 2 fixed to the installation plate 3, and the lower end of the multi-axis robot 2 mounted on the support column 1.

[0026] The specific working principle of this utility model: In one implementation, multiple columnar materials are placed in a tray, and the trays are stacked. During destacking, the robotic arm moves onto the tray, and the sliding cylinder 9 drives the parallel clamping cylinder 11 downwards. The gripper 13 clamps the columnar material, and the action is repeated to remove all the columnar materials from the tray. Then, the sliding cylinder 9 drives the parallel clamping cylinder 11 upwards. At this point, the lower end of the suction cup 6 is higher than the lower end of the gripper 13, and the suction cup 6 holds the tray, which is then moved away, completing the destacking function. The stacking process is the reverse of the destacking process, and the principle is similar, so it will not be described in detail here. This robotic arm can completely replace manual loading and unloading of columnar materials, and can simultaneously pick up columnar materials and trays. Automatic material handling is achieved during both destacking and stacking, and precise tracking of materials is achieved through a barcode scanner 7.

[0027] The above description provides examples of the preferred embodiments of this utility model. Any aspects not detailed herein are common knowledge to those skilled in the art. The scope of protection of this utility model is determined by the claims. Any equivalent modifications based on the technical teachings of this utility model are also within the scope of protection of this utility model.
