Welding online monitoring system

Abstract

The welding online monitoring system of the invention relates to a welding monitoring system. The welding online monitoring system comprises a main controller and a positioning detecting module, a welding gun magnetism detecting module, an alarming module, a fixture controlling module, a panel LED module and a digitron display module respectively connected with the main controller. The positioning detecting module can position precisely, the positioning information can be displayed by the panel LED module, if the positioning is not accurate, the alarming module will alarm, number of the welding points can be detected by the welding gun magnetism detecting module, and the number and the process state can be displayed by the digitron display module. Thereof, the invention can realize precise positioning and state indicating of parts placed on the fixture of the welding production line to prevent missed welding and mistaken welding during the welding process. The fixture controlling module can control automatic opening or closing of the welding fixture before and after the welding to improve the automatic degree of the welding production line and to relieve the working intensity of workers at the production line.

Description

technical field [0001] The invention relates to a welding monitoring system, in particular to an online welding monitoring system. Background technique [0002] With the development of control technology, more and more enterprises adopt robot welding, but the investment cost of using robot welding equipment is very high, often tens of millions, especially when the products are small batches with many varieties, it is even more difficult to take advantage of the advantages of robot batch manufacturing . However, with the manual welding method, the welding quality basically depends on the worker's technical level and on-the-spot performance. There is no automatic monitoring or testing, and only relying on the worker's self-inspection and visual inspection, which makes the welding quality of the workpiece very random, and it is difficult to guarantee the quality of mass production.

[0002] With the development of control technology, more and more enterprises adopt robot welding, but the investment cost of using robot welding equipment is very high, often tens of millions, especially when the products are small batches with many varieties, it is even more difficult to take advantage of the advantages of robot batch manufacturing

However, with the manual welding method, the welding quality basically depends on the worker's technical level and on-the-spot performance. There is no automatic monitoring or testing, and only relying on the worker's self-inspection and visual inspection, which makes the welding quality of the workpiece very random, and it is difficult to guarantee the quality of mass production. Stability, and since it is difficult to rework or repair substandard products after welding, welding should focus on process control

[0003] The traditional industrial production line body detection equipment is usually built by PLC control or directly using a simple trigger relay system. The disadvantages are that it is large in size, high in cost, not easy to install on the actual production line body, and has simple functions, which cannot meet the harsh requirements of the site. Specific requirements for environmental monitoring
