Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing automation technology, specifically to a robotic arm for automated material handling in mechanical manufacturing. Background Technology

[0002] A robotic arm for automated material handling in mechanical manufacturing is an automated device that can mimic some of the movements of a human hand to grasp and move materials. Its movements can usually be controlled by programming or preset instructions to achieve the process of automatically grasping, moving and placing items without direct human intervention.

[0003] A search revealed a Chinese utility model patent, CN216803435U, which discloses a robotic arm for automated material handling in mechanical manufacturing. Specifically, it relates to the field of automated material handling technology. The arm includes a worktable with a set of support rods fixedly connected to its four corners. A movable material handling mechanism is fixedly connected to the side of the worktable near the support rods. The movable material handling mechanism includes a sliding groove located in the middle of the side of the worktable near the support rods. A limiting groove is formed on one side of the inner wall of the sliding groove, and a limiting rod is slidably connected to the inner wall of the limiting groove. This utility model incorporates a motor, with a connecting rod fixedly connected to the side of a sliding block away from the sliding groove. One end of a lead screw is fixedly connected to the motor, which drives the movement of objects, saving time and effort and increasing efficiency. A sliding block is fixedly connected to the end of the limiting rod away from the bottom of the limiting groove. The sliding block extends along the depth direction of the sliding groove to the outside of the groove, and the side of the sliding block away from the limiting rod is slidably connected to the inner wall of the sliding groove, making the structure more robust and less prone to detachment.

[0004] However, the device lacks flexible handling capabilities. When in use, the electromagnet can only move back and forth in one direction and cannot move products to other locations, which often limits its use. Moreover, the device lacks the ability to easily replace gripping components. If the electromagnet malfunctions, it is difficult to replace, which in turn affects production efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a robotic arm for automated material handling in mechanical manufacturing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The system includes a slide rod 1, a slider 1 slidably connected to the outer surface of the slide rod 1, slider 2 fixedly connected to both ends of the slide rod 1, a slide rod 2 inserted into the inner wall of the slider 2, an electric telescopic rod 1 fixedly connected to one of the two slider 2 near the slider 1, a limit block fixedly connected to both ends of the slide rod 2, an electric telescopic rod 2 fixedly connected to one of the two limit blocks near the slider 2, an electric telescopic rod 3 fixedly connected to the bottom of the limit block, an assembly block fixedly connected to the bottom of the slider 1, and an assembly cylinder threadedly connected to the outer surface of the assembly block.

[0008] Preferably, a spiral retaining strip is fixedly connected to the bottom of the assembly block, a spiral fixing block is fixedly connected to the bottom wall of the assembly cylinder, a spiral groove is provided on the spiral fixing block, a spiral retaining strip is slidably connected to the inner wall of the spiral groove, a torsion spring is fixedly connected to the top of the assembly cylinder, a retaining cover is fixedly connected to the end of the torsion spring away from the assembly cylinder, a protrusion is slidably connected to the inner wall of the retaining cover, and an assembly block is fixedly connected to the side of the protrusion away from the retaining cover.

[0009] Preferably, a gripper is rotatably connected at the center of the bottom of the assembly cylinder, and a motor is fixedly connected at the bottom of the assembly cylinder near the gripper.

[0010] Preferably, the electric telescopic rod has a support plate fixedly connected to its bottom three ends, and the two support plates are symmetrically arranged about the slide rod.

[0011] Preferably, a crossbar is fixedly connected to the upper surface of the support plate near the electric telescopic rod three, and a caster wheel is rotatably connected to the bottom of the support plate.

[0012] Preferably, the two sliders are symmetrical about the vertical axis of the slider.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This automated material handling robot for mechanical manufacturing utilizes three electric actuators. In operation, activating these actuators moves slider one to a suitable position, starts the motor, and drives the gripper to pick up the item. Activating actuators again moves the gripper to the desired position, releases it, and the material handling is complete. The use of these actuators allows the gripper to move to any position and precisely pick up the item, achieving greater flexibility.

[0015] This type of robotic arm for automated material handling in mechanical manufacturing utilizes casters. During use, the cover is opened, causing the torsion spring to twist and separate the cover from the protrusion, releasing the initial restriction between the assembly block and the assembly cylinder. The assembly cylinder is then turned, causing the threaded groove on its inner wall to slide along the threaded pattern on the outer surface of the assembly block. The spiral clamp slides within the spiral groove on the fixed block until the assembly cylinder separates from the assembly block, along with the gripper, from the overall device. A replacement assembly cylinder with suitable grippers is then screwed onto the assembly block and the cover is tightened, securing the new grippers to the overall device. The various electric telescopic rods and motors are then activated, driving the robotic arm to handle the product, thus facilitating the replacement of different types of grippers.

The threaded groove on the inner side wall of the assembly cylinder 4 slides along the threaded pattern on the outer surface of the assembly block 3. The spiral clamp 5 slides in the spiral groove 7 on the fixing block 6 until the assembly cylinder 4 separates from the assembly block 3, and the gripper 11 separates from the whole device. Replace the assembly cylinder 4 with a suitable gripper 11, screw it onto the assembly block 3 and tighten the cover 9, fix the new gripper 11 to the whole device, start each electric telescopic rod and motor 12 to drive the robot to transport the product.

When in use, if it is necessary to change the work site, the staff can push the entire device to a suitable position by relying on the caster wheel 21, and then start the device to carry out the work. The movable robot can move freely between different work areas, adapt to various production tasks and changes in the work environment, thereby achieving the effect of improving equipment utilization.

[0028] In this embodiment, preferably, the two sliders 1 are symmetrical about the vertical central axis of the slider 2. In use, the two symmetrical sliders 1 provide more stable support for the sliding of the slider 2, ensuring that the slider 2 slides smoothly in the horizontal direction.

[0029] Working principle: In this embodiment, the robotic arm for automated material handling in mechanical manufacturing operates as follows: Electric actuators 1, 2, and 3 are activated to drive slider 1 to a suitable position.
