Description
Technical Field
[0001] This utility model relates to the field of automatic material handling technology, and in particular to a valve material handling device. Background Technology
[0002] Valve handling devices are mechanical devices used for automated handling of valve workpieces. During production or maintenance, they grab valves from the feeding table or storage location and accurately transfer them to the processing, inspection, or assembly station. These devices typically use mechanical grippers, vacuum suction cups, or magnetic adsorption mechanisms to stably grasp the valves and achieve precise movement through linear modules, robotic arms, or rotary cylinders. This ensures accurate positioning without damaging the workpiece, significantly improving production efficiency and reducing human error. They are especially suitable for high-precision, high-volume manufacturing assembly line operations. They can also be integrated with vision inspection or sensor components to optimize the picking and placing accuracy and stability.
[0003] A valve material handling device mainly consists of a clamping mechanism, a drive unit, a positioning component, and a control component. The clamping mechanism uses mechanical grippers or vacuum suction cups to firmly grasp the valve workpiece. The drive unit includes a linear module, a servo motor, or pneumatic components to achieve precise reciprocating or rotary motion. The positioning component is equipped with a guide rod or sensor to ensure accurate transfer position. The control component coordinates the actions of each component through a motion controller. The overall structure is compact and adapts to the needs of high-speed and high-precision production lines.
[0004] In the existing technology, the lack of lubrication in the existing valve feeding device will cause the moving parts such as lifting gear and guide rail to wear severely due to dry friction, resulting in a decrease in transmission accuracy, an increase in positioning deviation, an increase in motor load leading to increased energy consumption and overload risk, and direct metal contact will produce abnormal noise and vibration, which will lead to loosening or cracking of structural components and a significant reduction in equipment service life. Therefore, a valve feeding device is proposed to solve the above problems. Utility Model Content

[0041] Working principle: Due to the long-term lifting of the lifting robotic arm 1, the tooth surfaces of the gears and racks are scratched or deformed due to dry friction, resulting in positioning deviation and affecting the valve picking and placing accuracy. Therefore, a lubrication mechanism 3 is provided at its meshing point to lubricate the workpiece 6 and extend the service life of the device. On the outside of the drive platform 2, through the fixed connecting block 31, the lubricating oil stored in the oil tank 32 at the top of the connecting block 31 is delivered to the nozzle 36 through the oil pipe 33. The oil output is controlled by the cylinder 352 driving the limiting plate 34 to slide in the slide groove 353 opened inside the hollow plate 351, and finally the meshing point is maintained.
[0042] To facilitate daily maintenance of the device and adapt it to clamping various workpieces 6, a replacement mechanism 5 is provided at the gripper 57 to quickly replace the gripper 57. The user only needs to rotate the shift rod 53 located outside the alignment block 1 51 and the alignment block 2 52. The movement of the shift rod 53 drives the chuck 54 inside each to rotate. The chuck 54 aligns with the semi-circular hollow block 1 55 and the other half aligns with the semi-circular hollow block 2 56, so that the alignment block 1 51 and the alignment block 2 52 are no longer connected. Finally, the two are quickly separated and the gripper 57 is removed, realizing quick replacement.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
