Constant temperature welding laser controller

Abstract

The invention discloses a constant temperature welding laser controller. The controller and the laser controlled by it are in a split structure; it includes a main control board and a real-time temperature detection probe; the main control board is used for combining real-time temperature Information, after the precise algorithm operation carried in the microprocessor, output the laser power adjustment signal to the laser; the real-time temperature detection probe is used to realize the non-contact real-time temperature detection of the welding point, and the real-time temperature detection probe is a photodiode , the photodiode is connected with a drive circuit; the drive circuit is connected to the control center signal on the main control board, and the drive circuit is used to convert the signal detected by the real-time temperature detection probe into a voltage signal acceptable to the microprocessor on the main control board; A control terminal for realizing human-computer interaction is also connected to the control board. The controller has the technical effect that it can be separated from the laser and can realize high-precision constant temperature control on different types of lasers.

Description

technical field [0001] The invention relates to the technical field of laser welding, in particular to a constant temperature welding laser controller. Background technique [0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. The welding process is of heat conduction type, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses to the inside through heat conduction. The laser pulse width, energy, peak power and repetition frequency are controlled by the laser controller 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 various micro and small parts. [0003] As an important part of laser welding equipment, the laser controller is directly designed as an integrated structure with the laser in the prior art, that is, a laser is fixedly equipped with a controller; the ...
