Abstract

The invention discloses high-precision penetration control laser plastic welding equipment and a working method thereof, and relates to the technical field of laser welding. The equipment comprises aframe body, a lower electrical cabinet and an upper computer, wherein a pressure closed loop clamping and pressing mechanism is fixedly mounted on the upper surface of a double-station turntable. Thepressure closed loop clamping and pressing mechanism comprises a mounting base, a centering and balancing stand column, a pressing cover plate, a bearing plate, a first precision electric cylinder, asliding table, a supporting column, a self-selecting model, a second precision electric cylinder and a numerical display welding penetration measuring ruler. A PLC control system man-machine interfaceconnected with the upper computer is arranged above the frame body. The method can reliably ensure finished-product consistency, can adaptively and actively perform adaptive welding speed and displacement exploration, pre-welding and penetration presetting on different types of workpieces to be machined, the diversity requirements of plastic laser welding are met better, the welding precision requirement is met better and traceability analysis and control functions are achieved.

Description

technical field

[0001] The invention belongs to the technical field of laser welding, in particular to a high-precision penetration control laser plastic welding equipment and a working method of the high-precision penetration control laser plastic welding equipment. 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...
