Robot quick-change tool magazine

Abstract

The robot quick-change tool magazine comprises a box body, and a plurality of tool placing positions are arranged on the upper portion of the box body; tools are placed in the tool placing positions; the tool placing position is a U-shaped notch with a large opening and a small bottom, a crescent plate is arranged on the edge of one side of the U-shaped notch, the edge of one side of the crescent plate is a concave surface, the concave surface faces the tool placing position, and the crescent plate is provided with a rotating shaft; when the tool slides into or out of the tool placing position, the edge of the upper end of the tool slides from outside to inside by attaching to the concave surface of the crescent plate, the crescent plate is forced to rotate, and the tool placing position or the crescent plate is provided with a detection assembly used for sensing the position change of the crescent plate so as to judge whether the tool is in a warehousing state or not; according to the quick-change tool library for the robot, the robot can reliably, stably and safely grab tools by optimally designing the tool taking and placing position, process detection, information interaction and action interlocking, and assistance is provided for simple and quick deployment of the robot.

Description

technical field [0001] The invention belongs to the field of robot automation, in particular to a robot quick-change tool library. Background technique [0002] With the transformation and upgrading of the industry, the application of robots in the industry is becoming more and more common. In this context, higher requirements are put forward for the safety of robot applications and the simplicity of layout. Traditional robots replace end tools mostly through manual disassembly and assembly, which is time-consuming and laborious, and there are safety hazards and disadvantages, such as accidentally dropping the tool and hurting the operator, and the tool is large and heavy, making it difficult to install. Later, due to production needs, some quick-change tool library equipment also appeared. For example, the patent CN113161813A declares a tool quick-change device.

Problems solved by technology

Traditional robots replace end tools mostly through manual disassembly and assembly, which is time-consuming and labor-intensive, and there are safety hazards and disadvantages, such as accidentally dropping the tool and hurting the operator, and the tool is large and heavy, making it difficult to install, etc.

Later, due to production needs, some quick-change tool library equipment also appeared. For example, the patent CN113161813A declares a tool quick-change device. After the robot grabs the workpiece, there is no communication such as detection signals. Through purely mechanical detection methods, information cannot be formed. Closed-loop feedback, poor reliability, and potential safety hazards; patent CN110065086A declares an industrial robot tool library, which exists independently and cannot communicate with the main control equipment, and has poor adaptability to automated industrial scenarios. Secondly, the entire machine equipment is fixed by universal wheels. In practical application scenarios, it is often accompanied by vibration, and the equipment is prone to shift, resulting in position changes, which greatly reduces reliability. In addition, the robot pick-and-place tool has no in-position detection signal, and motion detection interlock cannot be formed, resulting in poor security.

[0003] These inventions do not solve the problems of stability, reliability, and safety in the process of picking and placing tools, and are poorly executable during use. At the same time, data communication is closed or not, which is contrary to the current needs of rapid robot layout.
