Abstract
Description
Technical Field
[0001] This invention relates to a gantry crane, specifically a gantry crane with light-load single-claw intelligent recognition. Background Technology
[0002] Gantry cranes, as core lifting equipment in industrial production, infrastructure construction, and logistics transportation, have become key equipment for loading and unloading bulk materials and hoisting heavy components due to their advantages of large span and large lifting capacity. Traditional gantry crane design has long been centered on meeting the needs of large, heavy-duty material handling, resulting in common industry problems such as large overall size, excessive structural weight, and high energy consumption. With the booming development of e-commerce and the explosive growth of express delivery and logistics volume, the drawbacks of traditional manual sorting and handling have become increasingly apparent. Not only are labor costs high, but long-term worker fatigue can also lead to sorting errors and material damage, severely restricting the efficiency and safety of logistics transportation. To address this pain point, this invention proposes a light-load single-claw intelligent gantry crane. This equipment can accurately locate materials through intelligent recognition technology, achieving efficient material gripping and precise placement at planned locations. Summary of the Invention

[0009] To achieve highly efficient, low-energy-consumption intelligent sorting and handling of materials, this invention prioritizes lightweight and intelligent design in its structural design. Safety factors are fully considered, and all mechanisms are compactly installed, minimizing redundancy. In terms of material selection, it primarily uses European standard 2020 aluminum profiles, carbon fiber, and lightweight, high-strength, low-cost 3D-printed parts. For intelligent control, it employs visual intelligent recognition technology to identify different materials, enabling the intelligent control system to formulate effective handling plans, thus achieving fully automated operation of the entire mechanism.
[0010] The present invention consists of a portal frame 4, a rotating lifting and grasping mechanism 3, a travel track 2, and an intelligent control system.
[0011] The store frame 4 adopts a combined structure of horizontal support aluminum rods 27 and vertical support aluminum rods 2, utilizing the high-precision characteristics of the geared motor 21 to control horizontal movement. By controlling the direction and speed of the geared motor 21, and relying on its unique body structure, the accuracy and stability of handling operations are ensured.
[0012] The rotary lifting gripping mechanism 3 is an independent gripping unit. During gripping and handling, the servo motor 18 controls the opening and closing of the servo gripper 1 and the rotation of the rotary gimbal 10, with the two components working together. The workflow of the gripping unit is as follows: First, the camera 24 identifies and locates the material, transmitting the identification information to the STM32 development board. After obtaining the position coordinates of the target material, it transmits the information to the control program of the geared motor 22 and the lifting stepper motor 15. The geared motor 22 drives the synchronous pulley 21 and controls the gripping mechanism to move on the horizontal support aluminum rod 26 under the action of the pulley block 25. Meanwhile, the lifting stepper motor 15 drives the synchronous pulley group 16, causing the linear guide rail 12 to move up and down on the linear guide rail fixed slider 17, so that the servo gripper 1 reaches the designated position and grips the material. The coordinated operation of all moving parts achieves high-efficiency and stable gripping and handling.
[0013] A vision recognition module is integrated into the intelligent control system. When the gantry crane receives a work instruction, the vision module first identifies the type of material and feeds the information back to the control system. Based on this, the control system formulates a handling plan and then issues control commands to the drive motors of each subsystem. The drive motors respond to the commands and drive each mechanism to move, bringing the actuator to the designated position, thereby completing the material grabbing and precise delivery to the target area.
[0014] A lightweight, single-claw intelligent recognition gantry crane boasts advantages such as light weight, high efficiency, and low energy consumption. Specifically: 1) Its lightweight nature stems from the use of lightweight materials throughout the machine body, such as aluminum alloy and carbon fiber, resulting in a total weight between 15kg and 20kg. 2) Its high efficiency lies in its ability to quickly identify, grab, and classify objects for placement using a single gripping mechanism. 3) Its low energy consumption is achieved because the entire machine's power source requires only a combination of 12V and 24V lithium batteries to meet its operational needs.
[0015] This invention discloses a light-load single-claw intelligent recognition gantry crane. With a suitable gripper, it can grasp and transport various types of small materials indoors, such as numerous small-volume materials like plastic parts and electronic components. In the field of logistics and handling, it can achieve high-efficiency and low-energy grasping and handling.
