Problems solved by technology

[0004] The speed of welding will affect the heat input per unit time. If the welding speed is too slow, the heat input will be too large, causing the workpiece to burn through. If the welding speed is too fast, the heat input will be too small, causing the workpiece to be impermeable.
For the hand-held laser welding machine, its welding speed is completely controlled by experience, and only experienced workers can operate it. For ordinary workers, it is difficult to grasp the welding speed, which directly affects the quality of welding.

Abstract

The invention discloses a speed feedback type small laser welding machine and belongs to the field of laser welding, a feedback sleeve is additionally arranged on the basis of an existing handheld laser welding machine, and the feedback sleeve feeds back the moving speed of the welding machine in real time, so that convenience is provided for adjustment of workers, and the welding quality is effectively improved. The moving speed of the welding machine is monitored through the linear speed sensor, the light-emitting feedback balls of different colors are controlled to emit light according to monitoring data, so that a worker knows the welding speed through the colors and adjusts the speed on the basis, the feedback sleeve arranged outside the welding head in a sleeving mode can weaken intense light emitted by a welding point, and the welding quality is improved. The feedback sleeve can effectively prevent eyes from being burnt, the trouble that a worker needs to wear protective glasses all the time is saved, in addition, the feedback sleeve can effectively prevent sparks from splashing during welding, and the sparks are prevented from being splashed to the skin of people to cause injury.

Description

technical field [0001] The invention relates to the field of laser welding, and more specifically relates to a speed feedback type small laser welding machine. Background technique [0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding is one of the important aspects of the application of laser material processing technology. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process is heat conduction, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses to the inside through heat conduction. By controlling the width, energy, peak power and repetition frequency of the laser pulse and other parameters to melt the workpiece and form a specific molten pool. Due to its unique advantages, it has been successfully applied in the precision welding of micro and small parts. [0003] Hand-held laser weld...
