Mobile telephone shell quality detection method

Abstract

The invention relates to a mobile telephone shell quality detection method which comprises two aspects, namely the process of detecting the mobile telephone shell edge and the process of detecting the mobile telephone back shell, wherein the adopted detection system comprises a control unit, a data acquisition module, a two-dimensional laser scanning sensor, an electric drive module, and mechanical devices used for respectively detecting the mobile telephone shell edge and the mobile telephone back shell; the process of detecting the mobile telephone shell edge comprises the following steps: the control unit sends out an instruction to the electric drive module to enable the electric drive module to control a fixture control mechanism to place a to-be-detected mobile telephone shell on a lower fixture, so as to tightly clamp the mobile telephone shell, and to enable the electric drive module to control a mobile telephone shell mounting platform to drive a fixture and the mobile telephone shell to rotate for one circle; the two-dimensional laser scanning sensor is used for performing data scanning on the lateral profile of the mobile telephone shell edge; the mobile telephone shell profile data received in real time is transmitted to the control unit; the control unit judges whether the mobile telephone shell edge appearance quality is qualified or not. The mobile telephone shell quality detection method has the advantages of low cost, easiness in realization, high reliability, high accuracy and precision.

Description

【Technical Field】 [0001] The invention belongs to the technical field of automatic detection and relates to a method for detecting the quality of a mobile phone shell. 【technical background】 [0002] In recent years, high-end smartphones have become more and more popular among consumers, and their market share has continued to grow. The parts and components in many internationally renowned mobile phone products are made in China, which brings huge business opportunities to China's electronics industry. But at the same time, mobile phone manufacturers have also put forward strict requirements for the quality inspection of high-end mobile phone parts and accessories. my country's mobile phone parts manufacturers are facing huge challenges. [0003] Take the case of a mobile phone as an example. Due to the manufacturing process, the appearance of some products will have quality defects such as dents, scratches, bumps, and burrs. At present, most parts manufacturers rely on manual in...

Problems solved by technology

[0003] Taking mobile phone casings as an example, due to reasons in the manufacturing process, some products may have quality defects such as dents, scratches, bumps, and burrs on the appearance.

At present, most parts manufacturers rely on manual inspection of the appearance quality of mobile phone casings, which is prone to false detection and missed detection, which brings a lot of economic losses to the manufacturers. Therefore, efficient and accurate intelligent automatic detection devices are urgently needed

Existing intelligent devices (such as invention patent CN102218406A) that use image processing technology to detect mobile phone shells require complex pattern recognition algorithms, and some also need to install detection lenses at multiple angle positions (such as utility model CN203455286U). The method is not easy to implement, and the accuracy and precision of detection are not ideal enough
