Embodiment 1

[0017] The multifunctional laser processing and manufacturing system proposed by the present invention is as figure 1 , 2 As shown, the whole system consists of a laser 1, a laser processing head 4, a multi-motion parameter robot 3 with a motor for carrying the laser processing head, a working platform 6 for carrying a workpiece 7 arranged under the robot 3, and a control The laser 1 and the control device of the robot 3 are composed. Wherein, the control device for controlling the laser 1 and the robot 3 includes: a computer 5, a laser control unit, a robot motion control unit and a coordination control unit. The laser output from the laser 1 is transmitted to the laser processing head 4 through the optical fiber 2 for focusing and output. The computer 5 is connected with the laser 1 and the multi-motion parameter robot 3; the laser control unit is connected with the laser 1; the robot motion control unit is connected with the motor on the multi-motion parameter robot 3; th...

Embodiment 2

[0021] The structure and workflow of the multifunctional laser processing and manufacturing system in this embodiment are basically the same as those in Embodiment 1, the difference is that, as figure 1 , 3 As shown, the vertical mechanical arm 3.3 of the multi-motion parameter robot also includes a horizontal mechanical arm 3.5 installed on the horizontal rotary joint 3.4, the end of the horizontal mechanical arm 3.5 is connected to the vertical rotary joint 3.6 and connected to the vertical processing arm 3.7 on the vertical rotary joint 3.6 , the rotation direction of the vertical rotary joint 3.6 is shown as J5 in the figure; the laser processing head 4 is fixed at the lower end of the processing arm 3.7. The five motion parameters of the laser processing head 4, including lateral displacement, longitudinal displacement, vertical displacement, horizontal rotary joint rotation, and vertical rotary joint rotation, can be coordinated and moved through the motion control devic...

Abstract

The invention discloses a multi-functional laser processing manufacturing system, which comprises a laser, an optical fiber, a laser processing head, a work platform, a multi-movement-parameter robot and a control device, wherein the multi-movement-parameter robot is used for bearing the laser processing head and a workpiece, and is provided with a motor; the control device is used for controlling the laser and the robot, and comprises a computer, a laser control unit and a robot control unit; the robot is used for controlling five movement parameters, including transverse displacement, longitudinal displacement, vertical displacement, horizontal rotation joint rotation and vertical rotation joint rotation of the laser processing head; and the computer is connected with the laser and the multi-movement parameter robot. The multi-functional laser processing manufacturing system has the advantages of capability of solving the problem that the laser processing head moves along a small-curvature track difficultly in the prior art, multi-movement-parameter controllability, expandability and suitability for laser processing of large-sized and complex curved workpieces in a plurality of environments.

Description

technical field [0001] The invention relates to a multi-functional laser processing and manufacturing system, in particular to a laser processing and manufacturing system which can be used to perform multiple methods on various complex curved surface workpieces. Background technique [0002] The current laser processing and manufacturing systems can be divided into three categories: one is the mechanical arm laser processing robot, the other is the laser processing center, and the third is the special equipment for laser processing. In these systems, the laser transmission adopts an optical folding mirror transmission system, and the high-power laser is transmitted from the laser to the processing surface through a hollow cavity structure (for example, US patent US4870246 "Laser processing robot for cutting and welding" and US5221823 " Laser machinery for welding and cutting"). In order to ensure the correct optical path of laser transmission in this method of laser transmi...
