Barreled welding wire allowance monitoring device and monitoring method thereof

Abstract

The invention relates to the technical field of monitoring devices, and discloses a barreled welding wire allowance monitoring device and a monitoring method thereof. The monitoring device comprises a barrel body, a weight monitoring unit, a height monitoring unit and a control unit, and welding wires are loaded in the barrel body. The weight monitoring unit is used for monitoring the weight of the welding wires. The barrel body is mounted on the weight monitoring unit. The height monitoring unit is used for monitoring the height of the welding wires. The height monitoring unit is mounted in the barrel body. The control unit is electrically connected with the weight monitoring unit and the height monitoring unit. The weight monitoring unit and the height monitoring unit are used for monitoring the welding wire allowance in a segmented mode, the weight of the remaining welding wires can be accurately measured, measurement errors are reduced, whether the welding wires need to be replaced or not at present is judged in advance, and welding wire waste is reduced as much as possible on the premise that production line stopping is not affected.

Description

technical field [0001] The invention relates to the technical field of monitoring devices, in particular to a monitoring device and a monitoring method for the remaining amount of barreled welding wire. Background technique [0002] The body manufacturing process requires laser brazing, CO 2 Welding processes such as gas shielded welding, these processes require the use of barreled welding wire. When replacing the barreled welding wire, it needs to go through processes such as robot-based adjustment, welding wire end grinding, wire threading, and wire feeding speed test, which usually takes more than 20 minutes. In order to reduce the impact of barreled welding wire replacement on production, it is necessary to use the production line shutdown time (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 waste of the remaining welding wire. Therefore, it is necessary to monit...

AI Technical Summary

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
