Welding production line weld-lack-proof welding method, weld-lack-proof device and automatic welding production line

Abstract

The invention discloses a welding production line weld-lack-proof welding method for detecting materials to be welded on welding stations on a welding production line. The welding stations are respectively provided with sensing devices, and the sensing devices are used for detecting whether the materials to be welded exist on the welding stations or not. The welding production line weld-lack-proof welding method comprises the steps of obtaining sensing information of the sensing devices on the welding stations at the current detection moment, wherein the sensing information presents that the materials to be welded are detected or are not detected; reading the sensing information of the second sensing device on the previous welding station of one welding station at the previous moment when the sensing information of the first sensing device at one welding station presents that the materials to be welded are not detected, judging whether the sensing information of the second sensing device at the previous detection moment presents that the materials to be welded are detected or not; performing weld lack warning if the materials to be welded are detected. By means of the welding production line weld-lack-proof welding method, the weld-lack preventing purpose can be achieved. The invention further discloses a weld-lack-proof device based on the method and an automatic welding production line.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a leak-proof welding method for a welding production line; and also relates to a leak-proof welding device and an automatic welding production line based on the method. Background technique [0002] The automatic welding production line is widely used in various welding fields because of its multi-station segmented automatic welding technology and high welding efficiency. In automobile manufacturing, welding is one of the important processes. With the continuous improvement of the technical level of the automobile body welding production line in my country, in order to improve the welding quality and reduce labor costs, the automatic welding production line of the reciprocating conveyor robot is usually used to complete the automatic welding work. The reciprocating conveying robot automatic welding production line is a reciprocating automatic conveying line to realize the transp...

Problems solved by technology

[0004] However, due to the high degree of automation of the welding production line, the requirements for the consistency of the state of the material are high. When there is a deviation in the state of the material, such as welding deformation during the welding process of the material, or the material does not fully enter the welding station during automatic transportation, so There will be two magnetic induction switches that can't sense the material, and the controller determines that there is no material at the station, and the welding line will have the situation of missing welding at this station.
