Problems solved by technology

[0007] (3) Restoration of damaged or worn parts
In addition, the system is bulky and expensive
All these have seriously hindered the wide application of this type of equipment in the manufacturing, processing and maintenance industries.
[0012] 2) Although the portable 3D coordinate machine can be used on site, manual intervention is required, and the system can only be applied to small detection objects, not large and complex detection objects
Under the existing detection mode, it is difficult to realize data detection, identification, processing integration and model reconstruction automation
[0014] 4) The functions of the above-mentioned equipment are single, and there is no possibility of redevelopment for different application backgrounds
Because the existing equipment cannot complete the detection task of large workpieces that are not easy to move at the processing site

Embodiment Construction

[0059] Through the articulated robot, the non-contact laser scanning head or laser sensor is used to detect the data of the complex unknown surface, and the six degrees of freedom of the robot are used to track the surface during the scanning process through adaptive path planning, as far as possible Ensure that the distance between the laser probe and the measured surface is constant, and the laser incident angle is perpendicular to the surface of the measured point. On the basis of ensuring the detection accuracy, it effectively overcomes the problem of detection blind spots and the problem that the scanning cannot be completed at one time. Use the environmental adaptability, anti-noise ability and workspace ability of industrial robots to solve the problem that traditional equipment is difficult to adapt to the industrial site, and through integrated software design and system process, solve the problem that traditional systems are difficult to realize data detection, identi...

Abstract

The reverse engineering robot system belonged to advanced manufacturing technique field comprises a detection head, a robot, a computer, a control cabinet, and a deflection machine. When user inputs basic detection parameters, the system programs automatically the scan path, controls robot, deflection machine and detection head to complete the detection. Wherein, it uses the robot control flexibility to realize the integrative path programming, uses the environmental adaptation ability and anti-noise ability of robot to satisfy industrial field require, and uses active automatic detection mode to realize automation and exploitability for post processing.

Description

technical field [0001] The invention belongs to the field of advanced manufacturing technology. Background technique [0002] Reverse Engineering (Reverse Engineering) was proposed as a new advanced manufacturing technology in the late 1980s to early 1990s. At that time, the automobile "2 mm project" initiated by Ford Motor Company, the leading American automobile company, posed an unprecedented challenge to the traditional manufacturing industry. It requires quality control to advance from the final product inspection and testing to the product development and design stage. Its purpose is to reduce development risks, reduce development costs, and speed up the cycle of successful product development. [0003] With the development of computer technology, 3D modeling technology has been widely used in various aspects of product and mold design, program review, automatic processing and manufacturing, management and maintenance by the manufacturing industry. In the actual deve...
