Bohai Piston, a leader in the field of pistons

Shandong Binzhou Bohai Piston Co., Ltd. is the only listed company in China with internal combustion engine pistons as the leading product, and it is the only specialized enterprise in China that can comprehensively produce pistons for all kinds of automobiles, ships, engineering and other power machinery; the manufacturing capacity of piston products ranks first in a single factory in the world, with a domestic comprehensive market share of 35%, and domestic III, IV and other high-end products have a market share of 60%. Foreign markets throughout North America, Europe, East Asia, the Middle East and other regions.

Background: the problem of process site needs to be solved urgently.

Due to the industry characteristics of many kinds of piston products and high precision, the requirements for workshop technology are extremely high. Bohai Piston has always adhered to the strict process system management, but also gained a lot of "the only one" honor. In the face of a more competitive market and the pursuit of excellence, they still face the following technological problems:

● design drawings can not be viewed in time: design drawings, process procedures, assembly simulation animation, etc., can not be viewed in time, resulting in order delay.

● process approval can not be carried out in real time: drawings, changes and other examination and approval process can not be carried out online in real time, resulting in work delay.

● quality problems can not be solved in time: workshop on-site production quality problems can not be solved by real-time online visualization interaction, which brings a lot of quality hidden dangers.

Huatian Software and Bohai Piston letter have been partners for many years. In combination with the management strategy of Bohai Piston which pays attention to innovation and effectiveness, Huatian Software combines the PLM system and document control system implemented in the previous period, and makes use of the advantage of mobile application to create a paperless system for Bohai Piston Workshop, which helps to improve the quality and efficiency of on-site process activities in Bohai Piston Workshop.

(1) pay attention to practical management, and mobile applications lead to more innovation

Through the paperless process software system, the first time to push drawings, process, change notice to the workshop, to maintain the latest technical data to guide product production. When problems are found on the spot, collect and submit them in time, and provide convenient feedback to designers for technical improvement.

1. Process data, quick browsing

● obtains the current production plan through integration with the ERP system, and then retrieves all the corresponding data of the product, including drawings, process cards, change orders and so on.

● data organization: through the first-level product model, second-level process information name and type list, view the relevant attributes of the data set, browse the process information content.

two。 Data query and Electronic Lending

The system supports the right to query and all queries, craftsmen and operators can clearly query (they have browsing rights) data, but also can find the relevant data in the system. For data that does not have browsing rights, the user can initiate a loan application. The loan application will be examined and approved through the PLM document control module, and the mobile end can browse after the examination and approval to ensure the query efficiency of the process documents.

3. Problem feedback, closed loop processing

Feedback on process problems in the workshop can be initiated immediately in the system. According to the form of system information, quality inspectors can describe the problem and collect pictures and videos. The completed system order will be automatically sent to the owner of this process data and alerted by message. In this way, the technician can find the problem accurately, deal with the problem in time, realize the closed-loop tracking of the problem feedback solving process, and ensure that there are no dead corners in the quality problem.

4. Process management, clearly visible

● workshop management can use this system to approve the approval and filing of the execution process in the PLM system.

● receives the process initiated by each business unit and selects the process approver of the corresponding business.

● records through the system, the process can be traced to the execution of each node.

5. Message management

Users can receive the message pushed from the PLM system to facilitate and process the message information in a timely manner.

(2) eliminate security risks and innovate mobile applications.

The mobile attribute of paperless process system not only brings great convenience to the query and browsing of process data, but also brings the hidden danger of enterprise data information leakage. As the technical data of intangible assets, security is the first condition to be considered. How to meet the security and confidentiality requirements of comprehensive protection of product data management?

1. Terminal Authorization Management of Mobile device

The mobile device management module is added in the PLM system, which manages the authorized devices and user information through authorization management, and binds the devices and users, thus restricting authorized devices and authorized users.

two。 Network Management of Mobile Devices

Through infinite routing APR binding, the establishment of unlimited private network of paperless process system can be realized in time, and strict security requirements and connection restrictions can be completed. Through the deployment settings of the mobile network, it is convenient to manage the wireless network of the mobile end.

3. Safety management of equipment system

Tablet computer (PAD), as a tool for daily entertainment, not only standardizes the work system, but also controls the installation and uninstallation of applications and keeps the application security of the hardware system by encrypting and locking non-work-related applications in the system.

Through these means of equipment management, the standard of the use of enterprise mobile devices is guaranteed. Combined with the limitations of the mobile terminal system, the security and confidentiality of the enterprise mobile devices and data are guaranteed to the greatest extent.

Application effect: green factory covered by mobile network, consumable material cost and management cost are greatly reduced.

The paperless workshop is the inevitable trend of enterprise information construction, and it is also the most basic starting point to realize the physical fusion of manufacturing process information under the industrial 4.0 environment. The application of the paperless process system of Bohai piston ensures the timeliness and accuracy of the enterprise process data pushed to the workshop, avoids the confusion of paper data version to the greatest extent, and greatly reduces the consumable material cost and management cost.

The application results are summarized as follows:

Convenience: craftsmen and operators use PAD and other mobile devices "scan and see" within the workshop to facilitate browsing of technical materials and 2D and 3D design data to ensure the quality and efficiency of production, installation and maintenance.

High efficiency: combined with drawing and document management, the drawings, process, change notice and other technical data to the workshop as soon as possible to ensure the accuracy and effectiveness of production. Mobile application greatly simplifies the process of borrowing drawings for operators and improves work efficiency.

Timeliness: timely feedback of problems in the workshop, combined with message notification, greatly shortens the processing time of the problem, and forms a closed-loop management of problem feedback business.

Compatibility: support the popular iOSAndroid system in the industry, support mainstream brands and models of smartphones and PAD devices.

Security: provide a variety of network deployment security strategies, support mobile device authentication authorization, access authentication authorization, data encryption, the use of memory browsing technology, mobile devices to achieve "seamless browsing" to ensure the security of mobile application data.
