A welding smoke collection device and method capable of automatically tracking and positioning welding points

Abstract

A welding fume collection device and method capable of automatically tracking and positioning welding points. The welding fume collection device includes a tracking control system and a welding fume exhaust pipe. The tracking control system includes a group of photoelectric sensors, an intelligent control unit, and a mechanical drive. The welding smoke collection method of the unit and the mechanical arm is to use the photoelectric sensors installed at different positions on the exhaust mask to sense the visible light, infrared rays or ultraviolet rays emitted by the solder joints, and the distance between the solder joint movement and the photoelectric sensors can be changed. The strength of the welding spot arc sensed by each photoelectric sensor changes, and each photoelectric sensor outputs an electrical signal to the intelligent control unit according to the sensed welding spot arc light intensity, and calculates the direction and direction of the welding spot movement. The distance is controlled by the mechanical transmission unit to drive the mechanical arm to move. The invention has high working efficiency, low energy consumption, low equipment cost, and can automatically realize the tracking of solder joints.

Description

technical field [0001] The invention relates to a welding fume collecting device and method capable of automatically tracking and locating welding spots. Background technique [0002] At present, there are two main methods for collecting and processing welding fume: one is to carry out overall ventilation in the welding operation area of ​​the workpiece to collect and process the smoke. large, high energy consumption, and unsatisfactory smoke removal effect; the other is to use a point-to-point method, that is, to collect and process the welding fume generated by a single welding point with a small exhaust port, which requires a small amount of exhaust air , has the advantages of flexible use, convenience, and energy saving. However, for larger welding workpieces or places where the position of the solder joints changes greatly, the exhaust port must be able to follow the movement of the solder joints. At present, there are automatic tracking arms for collecting welding fu...
