Positioning method, positioning device, terminal and storage medium

Abstract

The invention relates to the technical field of automatic welding, discloses a positioning method, a positioning device, a terminal and a storage medium, and can improve the positioning precision. Thepositioning device comprises a power supply module and a detection module which are electrically connected, wherein the power supply module is electrically connected with a grabbing part of a transfer manipulator or a main body workpiece; a first output end of the detection module is electrically connected with a control module of the transfer manipulator; and a first acquisition end of the detection module is electrically connected with the main body workpiece or the grabbing part. According to the positioning device a detection part, the power supply module, the grabbing portion of the transfer manipulator and the main body workpiece are utilized to form a series loop; when a component abuts against the main body workpiece, the whole device can form the series loop and the series loop is conducted; and when the detection module detects the current in the series loop, it can be judged that the component abuts against the main body workpiece, then the detection module gives the feedback to the control module of the transfer manipulator, and the control module can stop driving the transfer manipulator, so that whether the component is attached to the corresponding welding surface of the main body workpiece is effectively detected.

Description

technical field [0001] The invention relates to the technical field of automatic welding, in particular to a positioning method, device, terminal and storage medium. Background technique [0002] Before using the automatic welding system to complete the welding of a complex assembly composed of multiple parts, it must be assembled first. Due to the long time-consuming, low precision and poor consistency of the traditional manual assembly, it cannot meet the needs of efficient and high-quality automated welding systems. Therefore, it has become a common method of automatic and intelligent welding to use the transfer manipulator to grab the parts and combine them with the main workpiece, and then use the welding manipulator to complete the spot fixing and welding of the parts and the main workpiece weld. [0003] However, in the process of assembling welded parts with existing manipulators, some steps in the assembly process still simulate the previous manual assembly process,...

AI Technical Summary

Problems solved by technology

In this way, a complex mechanism will be installed at the end of the manipulator, and the efficiency of grabbing and handling will be reduced due to the addition of an action process.
