Robot-based multi-machine tool automatic feeding and discharging system and method

Abstract

The invention relates to a robot-based multi-machine tool automatic feeding and discharging system and method. The robot-based multi-machine tool automatic feeding and discharging system comprises a feeding conveying unit, a machine tool unit, a robot, a walking unit, a workpiece temporary storage unit and a discharging unit, wherein the feeding conveying unit, the machine tool unit, the robot, the walking unit, the workpiece temporary storage unit and the discharging unit are controlled by a control system; the feeding conveying unit is used for conveying products to be machined; the machinetool unit is used for performing machining processes; the robot is used for transferring workpieces among every machine tool and every temporary storage table; the workpiece temporary storage unit ismainly used for temporary storage of the workpieces; the robot stacks the workpieces on the discharging unit; the control system and a six-axis robot can achieve automatic linkage of the machining processes. Therefore, the robot-based multi-machine tool automatic feeding and discharging system is high in automation degree, saves labor cost and improves the production efficiency as well as the working safety.

Description

technical field [0001] The invention relates to the field of loading and unloading of machine tools, in particular to a robot-based automatic loading and unloading system and method for multiple machine tools. Background technique [0002] Traditional mechanical processing factories usually use manual loading and unloading of machine tools, and when workpieces need to be processed by multiple machine tools and multiple processes, it is even more necessary to manually move workpieces between each machine tool. The labor intensity is relatively high, which will not only affect the processing Precision quality will also lead to low production efficiency and increased production costs; therefore, the transfer of workpieces by robots has increasingly attracted people's attention; the patent number is 201510768441.0; the patent name is "robot-based machine tool loading and unloading processing system and processing method" patent The technical scheme of using robots for loading an...

[0002] Traditional mechanical processing factories usually use manual loading and unloading of machine tools, and when workpieces need to be processed by multiple machine tools and multiple processes, it is even more necessary to manually move workpieces between each machine tool. The labor intensity is relatively high, which will not only affect the processing Precision quality will also lead to low production efficiency and increased production costs; therefore, the transfer of workpieces by robots has increasingly attracted people's attention; the patent number is 201510768441.0; the patent name is "robot-based machine tool loading and unloading processing system and processing method" patent The technical scheme of using robots for loading and unloading is mentioned in the patent, but the trajectory of the robot in this patent is a circular trajectory, the entire system needs to occupy a large space, and it is only applicable to the scene of sequential processing of two machine tools; the system There is no buffer table to place the workpieces to be processed and processed. When the robot clamps the workpieces of the first machine tool to the second machine tool for processing, the first machine tool is in an empty state; the robot needs to move to the pick-up position after the placement is completed. The workpiece and the robot have a long running path; there is no control system to control the machine tool and robot, and the intelligence is low
