Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, specifically a gantry suction cup robotic arm for quartz stone slabs. Background Technology

[0002] During processing and transportation, quartz stone slabs often require robotic arms to handle the entire slab, facilitating the processing. Quartz stone slabs refer to artificial quartz stone, composed of over 90% natural quartz and approximately 10% colorants, resins, and other additives for bonding and curing. The slabs are produced using a manufacturing process involving negative pressure vacuum molding, high-frequency vibration, and heating curing, with the temperature varying depending on the type of curing agent.

[0003] In existing methods of handling quartz slabs, many robotic arms rely on binding to secure the slabs, which can lead to scratches and marks on the surface, affecting the aesthetics of the transported slabs. Furthermore, the robotic arms have limited capacity for securing and retrieving quartz slabs, requiring excessive manual intervention, thus reducing the efficiency of the equipment and impacting its performance. Therefore, a corresponding technical solution needs to be designed to address this issue. Utility Model Content

[0052] It should be noted that the specific model and specifications need to be determined based on the actual specifications of the device. The specific selection and calculation methods adopt existing technology in this field, and therefore will not be described in detail. The power supply and its principle are clear to those skilled in the art, and will not be described in detail here.

[0053] Working principle: When the lateral position needs to be adjusted, the drive motor 23 of the lateral adjustment mechanism 2 is started to automatically control the rotation of the drive shaft 231 and the gear cylinder 232. The meshing of the gear plate 22 makes the moving frame 21 located in the lateral adjustment position outside the gantry frame 1, and is stably supported above the slide rail 242 by the sliding plate 241 to assist in the movement.

[0054] The electric hydraulic device 32 and the electric hydraulic device 33 of the longitudinal adjustment mechanism 3 are activated to automatically control the lifting and lowering adjustment of the hydraulic rods 321 and 331, which precisely adjust the height of the adsorption mechanism 4. Furthermore, the limit rod 34 is located inside the limit cylinder 341 for auxiliary telescopic adjustment, which realizes precise movement and positioning in the planar space. This ensures the smoothness and precision of the translational movement, effectively avoids the precision loss caused by traditional sliding friction, and enables the robot to accurately adapt to the handling needs of quartz stone slabs of different heights and weights.

[0055] The vacuum pump 463 of the adsorption mechanism 4 is started, and a vacuum is drawn through the air extraction pipe 461, connecting pipe 462 and air collection pipe 46. Through the elasticity of the spring 452, the suction cup 45 is stably pressed above the quartz stone slab by multiple sets of vertical pipes 451. This not only ensures a firm adsorption of the quartz stone slab, but also adapts to different surface flatness, reducing the adsorption failure problem caused by uneven quartz stone slabs. It achieves efficient airflow control and can easily cope with quartz stone slabs of various sizes, weights and surface conditions.
