Abstract

The invention discloses a laser triangulation method-based three-dimensional measuring instrument. The laser triangulation method-based three-dimensional measuring instrument includes a laser device, an acquisition device, a movement device, a total control system and three-dimensional analysis processing software embedded in the total control system; the laser device and the acquisition device are fixedly arranged on the movement device; and the laser device, the acquisition device and a fixture for a product to be detected are arranged in a three-point manner. The invention also discloses a laser triangulation method three-dimensional measuring instrument-based flatness detection method. According to the laser triangulation method-based 3D measuring instrument and the flatness detection method of the invention, the laser device, the acquisition device and the movement device are highly integrated in the measuring instrument, and therefore, a scanning range can be set flexibly, and the measuring instrument can be compatible with the detection of products in various sizes; scanning and image acquisition are performed on the product to be detected through the laser device and the acquisition device; the three-dimensional analysis processing software analyzes and combines acquired data and generates the three-dimensional model information of the product to be detected and marks and distinguishes the relative height information of the surface of the product element by using different colors; and the three-dimensional analysis processing software analyzes and measures the above image information.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a laser triangulation-based 3D measuring instrument and a flatness detection method for product components. Background technique [0002] Today, with the modernization of industrial production, the degree of integration of mobile terminal products is getting higher and higher, and the connector structure used in mobile terminal products is becoming more and more complex. High-speed multifunctional connectors (USB Type-C) for mobile phone charging and data interaction, these connectors must be tested for the flatness of all soldering feet of the connector before being mounted on the motherboard; because this type of connector has a lot of soldering feet and It is a multi-layer arrangement. The traditional plane inspection method can only detect the solder pins on the outer layer, and cannot 100% control the quality of the product; while using a 3-dimensional detector for inspect...
