A kind of barreled welding wire allowance monitoring method

Abstract

The present invention involves the field of monitoring device technology, and a barrel welding wire margin monitoring method is disclosed. The monitoring device includes barrels, weight monitoring units, high monitoring units, and control units.The monitoring unit is used to monitor the weight of the welding wire; the barrel body is installed on the weight monitoring unit; the height monitoring unit is used to monitor the height of the welding wire;The control unit is connected to the electrical connection of the weight monitoring unit and the high monitoring unit.The present invention uses dual methods of heavy monitoring unit and high monitoring unit to monitor the welding wire margin waste, which can accurately measure the weight of the remaining welding wire, reduce the measurement error, and predict whether the current period of time needs to be replaced.Reduce welding welding waste as much as possible under the premise of production suspension.

Description

technical field [0001] The present invention relates to the technical field of monitoring devices, in particular to a method for monitoring the allowance of barreled welding wire. Background technique [0002] Laser brazing, CO 2 Welding processes such as gas shielded welding, which require the use of barreled wire. When replacing the barreled welding wire, it needs to go through processes such as robot-based adjustment, wire end grinding, wire threading, and wire feeding speed testing, which usually takes more than 20 minutes. In order to reduce the impact of barreled welding wire replacement on production operations, it is necessary to use the production line downtime (such as eating, after production, etc.) to replace the barreled welding wire in advance before the barreled welding wire is used up, but this will lead to the waste of the remaining welding wire. Therefore, it is necessary to monitor the amount of barreled welding wire in real time, and indicate when the b...

Problems solved by technology

However, when the barreled welding wire is replaced, the weight of the remaining welding wire usually does not exceed 10kg, which is far less than the range of the weight sensor, which will lead to a large error in monitoring the weight of the barreled welding wire, which will affect the accuracy of judging the replacement time of the welding wire

[0005] 2. The preset range when this method alarms is a fixed value, which cannot be automatically adjusted according to the actual production situation, which inevitably leads to waste of welding wire

[0007] 1. The laser positioning sensor often has an error of the order of mm. For barreled welding wire, it will cause an error of several kg at most, thus affecting the accuracy of judging the replacement time of the welding wire

[0008] 2. The alarm range of this method is a fixed value, which cannot be automatically adjusted according to the actual production situation, which inevitably causes waste of welding wire

However, this method lacks the ability to predict in advance, and often alarms when the production line is in production, resulting in the need to stop the production line to replace the welding wire, resulting in loss of production capacity
