Cell Phone Case Appearance Inspection Program-Mobile Phone 3C Industry-Specialized in visual imaging solutions_Non-standard optical customization-Dongguan Chuangshi Automation Technology Co., Ltd

Industry background

For cell phones, consumers are first attracted by the appearance and then fall in love with its performance. The quality of appearance directly affects the sales of cell phones. In the process of cell phone assembly and factory, it is necessary to carry out comprehensive testing on the back cover surface, side and R corner of the product, so as to avoid defective products from flowing into the market and affecting the reputation. With the expansion of cell phone production scale, production precision, traditional manual inspection is difficult to meet the detection needs, manufacturers use Chuangshi Automation cell phone case appearance inspection program has become inevitable.

Industry pain points

Back cover surface: scratches, indentations, bright marks, foreign colors, foreign objects, etc.

Side: scratches, nicks, foreign objects, indentations, dirt, foreign colors, plating off paint, etc.

R corner: notch, bump marks, plating off the paint, foreign color, etc.

For the appearance of defect detection, the traditional method of manual visual inspection, not only subject to subjective factors of interference, low efficiency, high cost, and limited by the physiological limitations of the human eye, can not be completed high-precision detection and detection of small defects, to a large extent, to improve the production cost, affecting the yield rate.

After joining Trunsign's automated cell phone case appearance inspection solution, a quality inspection line can complete simultaneous inspection of multiple defects in a surface. It can effectively help enterprises optimize the layout of the production line, improve the detection efficiency, and help enterprises to complete the development of automation.

Solution

In Terms of Hardware Selection

Inspection system by combining with automated production line, image acquisition components and light source position linkage, the product to be inspected is placed horizontally, the inspection surface is facing upward in a straight line movement, the line scanning camera is tilted at 48 ° to shoot.

On the Choice of Light Source

The program chooses to use tunnel light source (line array). Realize long-distance uniform irradiation, eliminating uneven reflection on the product surface.

In the Choice of Software

The program adopts Trunsight AI intelligent software V1.0 with a large number of built-in preprocessing algorithms, a simple and intuitive graphical interface is easy to use, reducing customer training and labor management costs. During the whole inspection process, the image processing steps and defect detection results are displayed in the interactive interface in real time and saved in the production log, which is convenient for tracing afterwards.

Advantages of the plan

For the appearance of defects detection, the traditional method of manual visual inspection, not only by the subjective factors of interference, low efficiency, high cost, and limited by the physiological limitations of the human eye, unable to complete high-precision detection and detection of small defects, to a large extent, to improve the cost of production, affecting the yield rate.

After joining Chuangshi Automation cell phone case appearance inspection solution, a quality inspection line can complete simultaneous inspection of multiple defects in a surface. It can effectively help enterprises optimize the layout of the production line, improve the detection efficiency, and help enterprises to complete the development of automation.
