A system and method for automatic calculation of product measurement points based on laser-guided measurement

Abstract

The invention discloses an automatic regular product three-dimensional measuring point location calculating system and method based on 2D laser-guided measurement. Automatic measuring point location calculation can be achieved, and the teaching time of test point locations is greatly shortened. The mode that the test point locations are taught manually is changed to the mode that calculation is automatically conducted through software, the measuring point location accuracy is improved, and errors generated in manual teaching are eliminated through software calculation. According to the system and method, the test location accuracy and repeatability can reach 0.03 mm, the measuring precision is effectively improved to 0.02 mm from 0.03 mm, and test point location sharing among devices can be achieved; the reference significance is achieved on three-dimensional test devices such as a tri-coordinate measuring machine, and the appropriate test angle can be regulated while the X-direction, Y-direction and Z-direction three-dimensional locations of a product are positioned.

Description

Technical field: [0001] The invention belongs to the technical field of production measurement, and in particular relates to an automatic calculation system and method for three-dimensional measurement points of regular products based on 2D laser-guided measurement. Background technique: [0002] With the rapid development of the 3C electronics industry, electronic products have been rapidly promoted and popularized. While pursuing high performance, people are paying more and more attention to product quality and appearance design, which requires more and more requirements in the design process and production process. The higher it is, the product itself is assembled from multiple parts, and the fit tolerance between the various parts of the appearance is also controlled to be smaller and smaller. At present, some automated equipment is used in the industry to measure the Gap, Offset and flatness between components. However, due to the complexity of the tested product, it a...

Problems solved by technology

[0005] For this reason, the technical problem to be solved by the present invention is that the measurement equipment used for electronic product measurement in the prior art has low measurement accuracy, can only be adapted to the measurement of positioning product plane X, Y direction, and cannot take into account the variation of product Z direction , and the angle of inclination during measurement, so as to propose a system and method for automatic calculation of three-dimensional measurement points of regular products based on 2D laser-guided measurement
