3C Consumer Electronics

Overview of the plan

As the largest field of machine vision application in China, 3C Electronics can see the presence of machine vision in various links of the electronic manufacturing industry chain, from imaging modules and USB connectors to devices such as phone frames and PC motherboards.

This includes application scenarios such as connector processing and assembly, screen alignment and fitting, and tablet scratch detection. In the entire consumer electronics industry chain mainly consisting of smartphones, computers, Bluetooth earphones, and smartwatches, Huahan Weiye provides five visual systems and visual intelligent detection equipment to assist the electronics manufacturing industry in creating unmanned and worry free factories, achieving cost reduction and efficiency improvement.

Visual defect detection of shielding cover/hardware components

Solution

iSense Al+2D detection
Testing items

Shielding cover: cracks at the R-corner position

Hole: presence or absence of holes, burrs/fibers inside the hole, etc

Membrane products: membrane pressure damage, dirt, misalignment, gaps, bubbles, etc.
Metal surface: pressure marks, scratches, dirt, etc
Detection result

(1) The fusion of traditional vision and deep learning technology has the characteristics of high accuracy and strong consistency;
(2) It can reflect actual object depth information from different perspectives, facilitating better presentation of defects. Using the pixel segmentation module in the deep learning module can identify the location, number, and area of defects.
