Requirements of flexible production in intelligent

Soliyang, a robot equipped with sky: requirements and Realization of flexible production in intelligent manufacturing

[text/PAN Minyao] compared with, flexible manufacturing is an ancient concept. With the development of new technologies including, big data, and so on in the past two years, now more mention is made of "" and "smart factory". Flexible manufacturing, which corresponds to rigid manufacturing, is an automatic production system based on group technology and controlled by computer. It can process a group or a class of products with similar shapes at the same time. It is suitable for the efficient manufacturing mode of multiple varieties and small batches, reducing the inventory of blanks and WIP and reducing the direct labor force

at the 2018 Suzhou Wuzhong Yangtze River Delta intelligent manufacturing summit held on the 12th, Suo Liyang, deputy general manager of sky robot, explained that in the production and manufacturing, the pace of production or the control of the whole production is realized through computers or some intelligent control systems, rather than completely through manual control

■ flexible production in intelligent manufacturing

under the general trend of technological development, industrial 4.0 ecosystem involves many technologies and modules. From the top level, or the foundation of smart factory comes from cloud security, cloud storage, big data, etc

the middle level involves the interconnection of various modules and systems, as well as the cooperation between them, including chips, sensors, and manufacturing management systems

at the manufacturing level, it involves customized tools, advanced materials, machine tools, AGV, etc. It can be seen that it only occupies a small part of the whole intelligent manufacturing

in soliyang's view, the requirements of flexible production involve seven aspects

first, the machine is flexible. When it is required to produce a series of different types of products, the difficulty of machine processing different parts with product changes

second, process flexibility. Ability to adapt to changes in products or raw materials when the process flow remains unchanged; The difficulty of changing the corresponding process to adapt to the changes of products or raw materials in the manufacturing system

third, the product is flexible and bright. The ability of the system to produce new products very economically and rapidly after product renewal or complete diversion; The inheritance and compatibility of useful features of old products after product update

fourth, maintain flexibility. Adopt a variety of ways to query and rotate the rotatable collet at a constant speed to deal with faults, so as to ensure the ability of normal production

fifth, production capacity flexibility. When the production volume changes, the system can also economically analyze and detect the ability of equipment. This is particularly important for manufacturing systems that organize production according to orders

sixth, expand flexibility. When production needs, it can easily expand the system structure, add modules, and form the ability of a larger system

seventh, operation flexibility. The ability to produce a series of products with different machines, materials and technological processes and the ability to process the same products with different processes

how to meet the flexibility of each link? Soliyang believes that the so-called high flexibility is equivalent to a person operating. The high flexibility of a person is mainly reflected in: first, through vision, sound, touch, etc., he can perceive the surrounding environment, followed by decision-making and implementation, and finally form a complete closed-loop control chain

to achieve flexibility, machines first depend on the decision-making of intelligent management system, and then integrate all kinds of sensors, machine vision, measuring equipment, IOT, etc. to achieve "perception". "Execution" refers to the requirements of completing production through the actuator, including industrial robots, CNC machine tools, AGVs, and various proprietary equipment. Only when the software and hardware are perfectly matched can their work become more and more "human"

■ requirements for industrial robots under flexible production

How can robots provide more powerful support for flexible manufacturing? Soliyang believes that the first is to improve the quality of industrial robots, including performance, life, reliability, safety, economy, appearance, maintainability, service, etc

"performance" includes accuracy, speed, acceleration, acceleration, rigidity, etc; "Service life" includes the trend of accuracy decay, wear trend, temperature and lubrication; "Reliability" generally refers to mean time between failures; "Safety" includes anti misoperation, anti-collision, soft and hard limit, and safety tips; "Economy" includes purchase cost, maintenance cost, service cost and the cost of secondary development required for it to cooperate with industrial robots and other equipment

"appearance", including industrial design, ease of use, human-computer interaction, painting appearance, etc., is particularly important for products to enter the international market; "Maintainability" includes quick maintenance, self diagnostic analysis, installation and replacement methods; "Service" mainly refers to rapid response, which is the advantage of domestic robot manufacturers and the point that customers care about very much

finally, in special application environments, such as humidity, corrosion, flammability and explosion, robots are required to be waterproof, dustproof, explosion-proof and corrosion-resistant

■ quality and cooperation of space robot

soliyang stressed that only when the three links of R & D, production and service are perfectly coordinated with the intelligent module can it be called high integration, which reflects the quality of industrial robots, and can better play the role of robots in flexible manufacturing

in terms of research and development, in order to achieve such a high absolute positioning accuracy within 0.1 mm, matchday has adopted a large number of different algorithms to improve the accuracy of the robot in space. At the same time, the space robot can drag the teaching through the teaching device to improve the efficiency of teaching

soliyang further said that a great feature of industrial robots is high rigidity and high speed, as well as maintaining high trajectory accuracy at high speed. In order to reflect the performance of the optimal tempo speed planning, the matching robot shows that the robot can run a distance of cans in less than a second, and the gap between cans is less than two millimeters

in addition, soliyang also introduced the cooperation between the robot and other intelligent modules, including 3D vision and force control grinding. In order to reduce the development time, the supporting robot has opened its bottom parameters to facilitate the secondary development of the robot

at the level of production management, matchday will carry out quality control in the whole production process. In the incoming inspection, in addition to the routine inspection such as measurement, testing and verification, the air tightness test shall be carried out for the parts with sealing requirements, from raw materials, blanks, cables to sheet metal parts, so as to ensure the quality of each part; For the problems of incoming materials, communicate with suppliers in time, and issue problem summary and improvement measures to fundamentally solve the problems

in the processing and inspection, all machined parts of the supporting robot are processed in the imported high-precision CNC constant temperature workshop, and the workshop temperature is maintained at ℃. Testing instruments are also world-famous brands to ensure the quality of parts. The critical zero dimension shall be inspected in three coordinates. In addition, full-scale inspection has been added to the first and last parts, and 100 inspections have been carried out for key processes to ensure the quality of parts

in the aging test of the control system, the driver and integrated cabinet enter the aging room for high-temperature test after completing the basic function test. When customers have customized needs, if there is an absolute accuracy requirement, the robot will be calibrated by matching the absolute positioning accuracy

finally, Pt robot actively carries out in-depth cooperation with its upstream, middle and downstream partners in the industrial chain, including core component suppliers, intelligent component providers, top-level designers of smart factories, and industry solution integrators

soliyang emphasized that there were nearly 200 integrators cooperating with Pt, Jobboekhoven, the lead author of this study, including the 3C industry, said: "So far, polishing, dispensing, spraying, loading and unloading, handling and palletizing in the machining industry, polishing, dispensing, spraying in the furniture and ceramic sanitary ware industry, handling and palletizing in the logistics industry, training in the education industry, event service providers, etc.

it is worth mentioning that as a robot body manufacturer, the supporting robot also provides a complete set of robot control system solutions. On September 19, the supporting robot released air3, this 3 The industrial robot with kg load integrates the technology with the highest speed, accuracy and efficiency at the present stage of the sky. At the same time, R3 products are also equipped with the latest second-generation drive control integrated control system arccd20, which is 47% smaller than the first generation control system. In the future, the robot will continue to develop new products, improve the quality of the robot in all aspects, and develop high-quality products

robot is a machine device that automatically performs work. It can not only accept human command, but also run pre arranged programs, and also act according to the principles and programs formulated by artificial intelligence technology. Robots are advanced integrators of cybernetics, mechatronics, computers, materials and bionics
