27 Cheng da Seiji: Let the intelligent equipment for the popularization of "black technology" wings
If we want to list the most transformative products in recent years, people may talk about the smartphone in their hands, the new energy vehicles when traveling, or the autonomous driving experience gradually reflected into reality, as well as the apps rapidly entering the public's view based on the development of big data, cloud computing and other technologies.
In fact, the birth of these products, and their application to ultimately change people's lives, is also closely related to the development of a small part: the optical lens. A good lens with higher accuracy and larger volume is behind the high-frequency change and innovation of a whole industry chain. Ningbo Chengda Precision Machinery Co., Ltd. located in Yuyao is an important part of this driving wave.
The author walked into the workshop of Chengda, a set of lens cutting and unloading machine is being carefully adjusted by engineers, and after reaching the standard, these "big" will be sent to some optical industry enterprises in the factory, the formal start of production work.
The intelligent equipment represented by the lens shearing machine is the incision of the development opportunity of chengda.
Start with zero to one.
Smart equipment, can be in which industries to display their talents? What industries will it work well with?
These are the two questions that Fu Cheng, chairman of Ningbo Chengda Precision Machinery Co., Ltd. thought about most when he decided to start his own business eight years ago.
In 2010, Fu Cheng was invited to work in a cigarette lighter manufacturing enterprise in Cixi to participate in the automation renovation project of the factory's production equipment. However, lighter products low added value, therefore, this kind of product production process automation, intelligent transformation, the cost factor has become a big constraint, technology is difficult to breakthrough progress, which also let Fu Cheng determined to devote himself to a broader stage.
In 2013, Fu Cheng and several partners left the cigarette lighter manufacturing enterprise. At that time, smartphones were still in the ascendationand 5G concepts were emerging, and the mobile phone industry was facing a broad and disruptive shakeout. On the other hand, the demand for product performance is constantly improving at the consumer end, and the production end is constantly improving the production requirements for related spare parts.
In this context, it is undoubtedly a promising choice to find a breakthrough in the development and application of intelligent equipment in the mobile phone industry chain.
"At first, we wanted to get involved in the back panel industry of mobile phones, but we soon found that the product was not a '0 to 1' choice, but more like a '1 to 1.1' polishing, the biggest change in production is the change of materials, and the space for smart equipment to play here is limited." Fu cheng recalled.
After repeated research and analysis, fu Cheng's team finally aimed at the small lens on the mobile phone. "At that time, people for the quality of the mobile phone photo imaging have sensitivity, some phones have even started double as a selling point, the mobile phone pixels requirements from 300000 to 2 million, 4 million or even tens of millions of the earliest, behind the change of this magnitude represents the process from manual processing to more sophisticated equipment and technology involved, for us, It's definitely an area of opportunity."
A set of equipment through more than 20 generations of replacement
In 2015, Ningbo Chengda Precision Machine Co., Ltd. was formally established, mainly engaged in the r&d and production of non-standard automation equipment, which also means that from the selected direction to the equipment on the production line, there is a long period of running-in period.
In 2015, Fu Cheng led the team to contact with the optical lens production enterprises. Starting from some small projects, they gradually came into contact with the core links and core equipment of lens production.
They noted that at that time, the black material cutting process in lens production was still semi-automated, many steps needed to be done manually, and it was difficult to improve the yield of the product, so there was a lot of room for modification.
Therefore, they took this as a starting point and participated in the design of intelligent equipment. After more than 20 iterations, it took more than a year before they finally had a set of lens shearing and swinging machine.
"With this equipment, the customer's cutting rate of lenses has reached 99 percent from around 80 percent in one fell swop, and it can also achieve 24 hours of uninterrupted operation, greatly increasing production and sales." Fu cheng is proud of this achievement, but he is more happy that the high precision and professional products brought by the automatic and intelligent production also laid a foundation for customers to get more "heavyweight" orders.
Cutting machine is just one of the many r&d achievements of Chengda. In 2017, the development of Chengda officially into the outbreak period, multi-line equipment research and development also rolled out.
In chengda's factory, there are also inking machines that automatically absorb lenses with mechanical arms and place them on inking shafts, MTF detection machines for optical lenses such as mobile phones, vehicles and security, and even intelligent sorting and storage systems produced by supporting factories. Among these "iron and steel workers", AOI testing equipment is the expectation of Fu Chengxin.
It is understood that AOI testing equipment was established and developed by Chengda last year. According to the physical structure of products, the equipment takes photos of products from multiple angles and uses deep learning algorithm to detect defects of products. Deep convolutional neural network was used to extract the higher-level features of defects. At the same time, deep learning was used for regression calculation of defect size to reduce the influence of external environment on defect size extraction.
"There is a wide range of applications for this technology, and it is currently required in many industries. We expect this machine to be a new growth point for our company in recent years." Fu cheng said.
Six years later, chengda Seiji has become a real high-tech enterprise, focusing on the development, design and manufacturing of automation equipment, to provide customers with comprehensive solutions to promote intelligent manufacturing.
Chengda Precision machine high-speed development can not be separated from the accurate judgment of the industry, in the development of key nodes are firmly seize the opportunity of domestic market consumption upgrading, improve the core technology, promote the innovation chain, the depth of the industrial chain integration, further stronger, bigger and better, so as to achieve high-quality development.
According to Fu Cheng, chengda Seiki's annual R&D investment accounts for more than 6% of its annual sales, and has signed industry-university-research cooperation agreements with Ningbo Institute of Materials, Chinese Academy of Sciences, and established open innovation and entrepreneurship platforms.
The company's team has expanded from five or six people to more than 160, and the r&d team is still expanding. At present, Chengda fine machine with optical series of products selected yuyao city individual champion cultivation enterprises. Fu cheng said that the company will continue to look at the global market, follow the development trend of The Times, improve the level of independent research and development, and strive to achieve the goal of doubling the output value this year.
