Embodiment Construction

[0060] The present invention is a digital quality inspection method for large-scale wallboard parts, and the steps of the method are shown in figure 1 , see the measurement process figure 2 , the specific steps are as follows:

[0061] Step 1: Initialize the operation before measurement, including: fixing the wallboard parts to be tested, dividing the scanning area of ​​the wallboard parts to be tested, and arranging the position of the laser tracker and the joint arm.

[0062] The position of the laser tracker is fixed during the measurement. When dividing the scanning area of ​​wallboard parts, it should be noted that there must be a common overlapping area between different areas. This overlapping area will be used to arrange the splicing points. Select a wall panel with a length of 2.8m and a width of 0.8m as the detection object. The scanning range of the articulated arm is a spherical measurement space with a radius of 2.5m, so it is only necessary to divide the wall...

Abstract

A large wallboard class part digitized quality detection method includes the steps of firstly, conducting initialization operation before measurement, namely, fixing a wallboard class part to be measured, arranging the position of a laser tracker and the position of an articulated arm and conducting scanning region partition on the wallboard class part to be measured; secondly, arranging wallboard positioning points and point cloud registration points and recording the positions of the points through the laser tracker; thirdly, obtaining point cloud data and registration point coordinates in each region through the articulated arm; fourthly, obtaining a point cloud of a whole wallboard; fifthly, comparing the point cloud with a model and outputting the detection result. When detection is conducted on the large wallboard class part through the method, the accuracy is high, the operation is simple, and the use effect is good.

Description

technical field [0001] The invention relates to a digital quality detection method for large-scale wallboard parts, which is a detection method for large-scale wallboard parts by using a variety of digital equipment, and can be used for the quality of large-scale wallboard parts in the aerospace and automobile industries. Detection belongs to the field of digital measurement and computer integrated manufacturing. Background technique [0002] Large wall panel parts have the characteristics of large size, complex shape and poor structural rigidity. The forming quality inspection method of wallboard parts has changed from the traditional geometric analog inspection method to the digital inspection method. At present, its main quality inspection methods include laser tracker inspection and articulated arm inspection. [0003] 1. Laser tracker detection method [0004] The laser tracker detection method belongs to the contact detection method. The contact digital detection m...
