A variety of mobile phone parts in China gradually in short supply state

As the world's largest mobile phone manufacturing center and the largest mobile phone consumer market, a variety of mobile phone parts in China gradually in the state of supply, the quality of related products also surfaced, become a common industry problems. In response to this situation, recently, Beijing state-led Instrument Technology Co., Ltd. (hereinafter referred to as "the state Instrument") developed for mobile phone parts quality testing of automatic new equipment, the equipment using machine vision, optical testing and other international advanced technology, detection efficiency up to 180 tablets per minute, Can effectively reduce the domestic handset parts manufacturers of quality control costs, enhance its international market competitiveness.

Mobile phone spare parts refers to the composition of the mobile phone machine pieces, replaceable parts and accessories for use, including speakers (or small horn), receiver, handset, vibration motor (buzzer), VCM coil motor, LCD screen, line, touch screen, mobile phone keypad, camera, shell, battery, charger, Mobile power, headphones, data cable and so on. Related people, the manufacture of an advanced multi-functional smart phone, at least 25 important parts needed.

like speakers, receivers, handsets, vibration motors, VCM coil motors (mainly for mobile phone cameras), headphones, etc., are important mobile phone parts, specific analysis, the above these types of mobile phone parts of the composition of materials, all contain small magnetic workpiece, such as NdFeB permanent magnet materials ( Rare earth permanent magnet material in a magnetic prominent, when this kind of special materials are used in mobile phone parts, most of them are made into a piece or a wafer-shaped workpiece.

Current domestic and foreign mobile phone industry generally use this kind of flake parts, but the domestic manufacturers have been using the backward manual detection means, affecting the normal production and quality control efficiency. According to the author from a manufacturer to understand the case, the factory due to the large production of magnetic materials, the daily need to test the piece of material for 1.5 million pieces, to this end, the factory arranged more than 20 testing workers, work more than 10 hours a day ... Even so, can only do 1/3 of the sampling. And the delivery of products, also often appear problems, the customer returns often happen.

These reasons lead directly to the production of Chinese handset parts manufacturers, but they do not have the product advantage, the lack of detection links, directly affect the manufacturers and profits. In addition, the pressure of workers, emotional fluctuations, the rising cost of human resources, which led to the increase in the manufacturer's economic and management costs. The most serious consequences will lead to the loss of competitive advantage in international markets and the risk of being eliminated from global markets.

Thus, the traditional manual detection means can not meet the needs of the vast number of mobile phone parts manufacturers, and intelligent automatic testing equipment will become a solution to the Trump of industry problems, this is the entire mobile phone parts industry industry upgrade direction.

In the context of such an industry, the Beijing state-led instrumentDevice into the research force, research and development of "mobile phone spare parts comprehensive testing equipment scheme", the program can quickly detect pieces of mobile phone parts of the size of material and appearance defects, these parts include the above speakers (or small horn), receiver, handset, vibration motor, VCM coil motors. In addition, the device scheme after a small amount of modification, can be applied to all kinds of NdFeB permanent magnet products, all kinds of magnetic guide, round or square magnets, magnetic rings, gaskets, washers, nuts and other small parts or pieces of workpiece size and appearance of the inspection. The

Device uses optical control technology and machine vision detection technology, which is mainly used in Non-contact optical measurement to complete the detection. The system is composed of industrial computer, digital acquisition card, motion controller, test unit, material transmission Unit and sorting unit. The equipment not only can quickly detect all kinds of mobile phone parts of the chip workpiece size and appearance defects, but also automatic sorting, detection process with fast, accurate and efficient characteristics. The emergence of the equipment to solve the vast number of mobile phone manufacturers of the urgent need for it to create a higher value.

with the development of mobile phone parts industry, will certainly lead to mobile phone parts detection technology innovation, in the future development, China's mobile phone parts testing will be a comprehensive trend of automation and intelligence, so as to enhance the domestic mobile phone parts manufacturers in the international market competitiveness. As an advocate of domestic custom testing, the automatic testing equipment developed by Beijing state-led instrument has provided a new testing mode for a large number of mobile phone spare parts manufacturers, which has great application value and market potential.
