Wen Lisheng: The Construction of Clothing Ultra-Flexible Manufacturing Mode (Part II)

(continued)

In the dynamic modular production line, according to the manufacturing process of the garment product, the modular station can dynamically move the new production line during the time-saving. The dynamic process plays an important role in the intelligent AGV and the robot, especially the AGV trolley. The conveying material can also carry the sewing equipment as a dynamic module station to participate in the dynamic production line construction, so the intelligent AGV and the robot are the most important devices to completely subvert the traditional production line. See Figure 4.

3) Realize the ultra-flexible manufacturing mode to build a smart manufacturing space for man-machine integration

The ultimate goal of the ultra-flexible production model is to build a complete intelligent manufacturing space for human-machine integration. The space consists of three levels: the intelligent decision-making layer, the manufacturing execution layer, and the equipment execution layer. The intelligent manufacturing decision-making layer combines a new generation of artificial intelligence technology + big data technology + people; the manufacturing execution layer integrates industrial IoT technology + wireless service network technology; the equipment execution layer integrates robot technology + intelligent machine technology + people, thus achieving Intelligent manufacturing space for man-machine integration.

First of all, robots and sewing equipment in the intelligent manufacturing space system are carriers of artificial intelligence, such as machine learning, machine vision, image recognition, etc. in artificial intelligence. The robot realizes the calibration work by compensating for the lens distortion and the adjustment coordinate of the image coordinates and the external three-dimensional coordinates, identifying the target object by extracting the image feature value, the gray value, etc., and then performing the positioning and detection according to the target position and the coordinates of the own coordinates, thereby completing the action. instruction.

Secondly, the function of the intelligent robot is to capture and transport the garment parts and cooperate with the sewing. For example, the robot grabs the conveying template, the robot adsorbs the work surface to complete the moving movement of the material, and the movement of the piece through the table air flow, the robot moves through the suction, etc. .

Thirdly, a dynamic module station is a unit CPS. The unit level CPS can automatically generate data including “state awareness-real-time analysis-scientific decision-precision execution” through intelligent sewing equipment and robots, its own embedded software system and communication module. The closed loop of the flow realizes the optimal allocation of resources within the working capacity of this dynamic module chemical bit.

Finally, the function of the intelligent sewing equipment is to cooperate with the robot to complete the sewing of the garment and complete the production required. As shown in the sequence of a, b, c and d in Figure 6, the intelligent sewing equipment is equipped with machine vision and The ROKAE robot cooperates with the work of grasping, positioning, automatic sewing and post-sewn placement.

4 Conclusion

The construction of garment ultra-flexible manufacturing mode is based on the traditional lean production theory. Under the production mode of intelligent manufacturing and flexible production, the process equipment of the traditional modular manufacturing process is intelligent, and the “modular + intelligent” of the station and production line. New production methods. In the process of transformation and innovation, garment enterprises must change from the personalized and flexible production methods of digitalization and network production to the ultra-flexible manufacturing mode of clothing. The following two points must be achieved: First, according to Xiong Peter’s innovation theory, we should not Only stay on the dividends brought by the innovative and customized flexible production, and fall into the “innovation trap”. On this basis, do not be restrained by the old technology that has been innovated, and enter the more profitable clothing ultra-flexible manufacturing as soon as possible. Model new technology track. See Figure 7.

Second, we must form a dynamic modular production station and production line without fixed pipelines in the form of “person + intelligent robot + intelligent machine”, especially the sewing station and production line to realize the real intelligence of garment modularization. Ultra-flexible manufacturing model. (End of the article)
