Description

Technical Field

[0001] This utility model relates to the technical field of material handling robots, and in particular to a robot for intelligent material handling carts. Background Technology

[0002] A robotic arm is an automated device that mimics certain movements and functions of a human hand and arm to grasp, move objects, or operate tools according to a fixed program. Its key feature is that it can be programmed to perform various pre-defined tasks. In terms of structure and performance, it combines the advantages of both humans and machines. The robotic arm was the earliest industrial robot and also the earliest modern robot. It can replace heavy human labor to achieve mechanization and automation of production. It can operate in hazardous environments to protect human safety, and therefore is widely used in machinery manufacturing, metallurgy, electronics, light industry, and nuclear energy sectors.

[0003] In intelligent manufacturing processes, we use robotic arms to grab materials and then place them into material transport vehicles. This process reduces the efficiency of material handling for workshop workers. However, the bases of existing robotic arms are fixed to the vehicle body, which means that the height of the material bin needs to be consistent with the height of the robotic arm to allow materials to enter. But robotic arms generally grab materials from the ground, resulting in a relatively low material bin, reduced storage space, and decreased material transfer efficiency. In addition, when the robotic arm grabs materials from the transport vehicle, it also needs to adjust the vehicle body position to expand the grabbing range, further reducing loading efficiency. To address this, we propose a robotic arm for intelligent material handling vehicles. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a robotic arm for intelligent material handling carts.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a robotic arm for an intelligent material handling trolley, comprising a base, a material bin mounted on the top of the base, a movable hole in the base, a first screw movably disposed in the movable hole, a movable block threadedly connected to the first screw, a lifting cylinder for adjusting the height of the robotic arm body mounted on the top of the movable block, a lifting assembly disposed inside the lifting cylinder, the lifting assembly including a lifting plate movable inside the lifting cylinder, a second motor fixedly mounted at the center of the bottom of the lifting cylinder, a second screw connected to the output end of the second motor, the second screw threadedly connected to the lifting plate, and the top of the lifting plate connected to the robotic arm body via a lifting rod.

[0006] Preferably, the base of the vehicle is provided with drive wheels around its bottom, the material bin has a discharge port at the bottom of the end away from the movable hole, the material bin is equipped with an electric telescopic rod, and the bottom end of the electric telescopic rod is connected to a movable baffle to block the discharge port.

[0007] Preferably, the material bin is fixedly installed with limit seats on both sides of the discharge port, and the movable baffle moves within the limit seats.

[0008] Preferably, a first motor is fixedly installed at one end of the movable hole on the vehicle base, the output end of the first motor is connected to the first screw, a limit rod is fixedly installed inside the movable hole, and both ends of the movable block pass through the limit rod.

[0009] Preferably, a positioning rod is fixedly installed inside the lifting cylinder, the lifting plate moves through the positioning rod, and a mechanical claw for grasping materials is connected to the top of the robot body.

[0010] Preferably, the bottom of the robotic arm body is provided with a rotating seat, and the lifting cylinder moves within the movable hole.

[0011] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0012] 1. The lifting plate on the second screw is driven by the second motor to rise under the action of the positioning rod, thereby increasing the height of the robot body to grasp the material, thus increasing the height of the material bin and increasing the storage space of the material bin;

[0013] 2. The movable block on the first screw driven by the first motor reciprocates horizontally under the action of the limit rod. The movable block drives the lifting cylinder and the robot body to move back and forth at one end of the base, which increases the gripping range of the robot body on the material. Multi-directional feeding can be achieved without adjusting the base, reducing the labor intensity of the operator.

[0014] 3. The movable baffle moves upward in the limit seat via the electric telescopic rod, opening the discharge port of the material bin and realizing the discharge of materials in the material bin.

Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0021] Example: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a robotic arm for an intelligent material handling cart includes a base 10, a material bin 11 mounted on the top of the base 10, a movable hole 12 in the base 10, a first screw 20 movably disposed in the movable hole 12, a movable block 21 threadedly connected to the first screw 20, a lifting cylinder 40 for adjusting the height of the robotic arm body 30 mounted on the top of the movable block 21, a lifting assembly inside the lifting cylinder 40, the lifting assembly including a lifting plate 41 movable inside the lifting cylinder 40, a second motor 42 fixedly mounted at the center of the bottom of the lifting cylinder 40, a second screw 43 connected to the output end of the second motor 42, the second screw 43 threadedly connected to the lifting plate 41, and the top of the lifting plate 41 connected to the robotic arm body 30 via a lifting rod 44.

[0022] The first screw 20, in conjunction with the movable block 21, drives the lifting cylinder 40 and the robot body 30 in the movable hole 12 to move horizontally, expanding the material grasping range. The second screw 43 and the lifting plate 41 in the lifting cylinder 40 work together to raise the material grasping height of the robot body 30, thereby increasing the height of the material bin 11 and increasing the storage space of the material bin 11.

[0023] See Figure 1 , Figure 2 and Figure 4 The base 10 has drive wheels 13 around its bottom. The material bin 11 has a discharge port 14 at the bottom of the end away from the movable hole 12. The material bin 11 is equipped with an electric telescopic rod 15. The bottom of the electric telescopic rod 15 is connected to a movable baffle 16 that blocks the discharge port 14. Limit seats 17 are fixedly installed on both sides of the discharge port 14 in the material bin 11. The movable baffle 16 moves within the limit seats 17.

[0024] The electric telescopic rod 15 drives the movable baffle 16 to rise in the limiting seat 17, opening the discharge port 14 of the material bin 11 and realizing the discharge of materials in the material bin 11.

[0025] See Figure 1 , Figure 3 and Figure 4 A first motor 23 is fixedly installed at one end of the movable hole 12 on the base 10. The output end of the first motor 23 is connected to a first screw 20. A limit rod 22 is fixedly installed inside the movable hole 12. Both ends of the movable block 21 are movably inserted through the limit rod 22. A positioning rod 45 is fixedly installed inside the lifting cylinder 40. The lifting plate 41 is movably inserted through the positioning rod 45. A mechanical claw 31 for gripping materials is connected to the top of the robot body 30. A rotating seat 32 is provided at the bottom of the robot body 30. The lifting cylinder 40 is movable inside the movable hole 12.

[0026] The first motor 23 drives the movable block 21 on the first screw 20 to reciprocate horizontally under the action of the limit rod 22. The movable block 21 drives the lifting cylinder 40 and the robot body 30 to move back and forth at one end of the base 10, thereby increasing the gripping range of the robot body 30 on the material.

[0027] Working principle: The drive wheel 13 drives the base 10 to the designated loading position. The robot arm body 30 grabs the material column on the ground. The second motor 42 drives the lifting plate 41 on the second screw 43 to rise under the action of the positioning rod 45. The lifting plate 41 drives the robot arm body 30 to rise to a certain height through the lifting rod 44. The robot arm body 30 then places the grabbed material into the material bin 11. Then the second motor 42 reverses to reset the robot arm body 30 to achieve the next grabbing action.

[0028] During the material grabbing process, the first motor 23 drives the movable block 21 on the first screw 20 to reciprocate horizontally under the action of the limit rod 22. The movable block 21 drives the lifting cylinder 40 and the robot body 30 to move back and forth at one end of the base 10, which increases the grabbing range of the robot body 30. Multi-directional feeding can be achieved without adjusting the base 10, reducing the labor intensity of the operator.
