The global manufacturing industry continues to face the problem of declining labor force year by year. To solve the crisis of lack of work, the “unmanned factory†in the past few years can be said to be very strong. Manufacturers believe that human beings have problems with overwork and lack of work, and may be fatal because of operational errors, so why not let robots replace humans?
But can robots really work once and for all? Careful observation, in fact, the market has begun to turn to the smart manufacturing strategy in recent years, European and American manufacturers are no longer just researching how to develop robot-led unmanned factories, but more focus on how people interact with machines and Matching, in order to effectively play each other's value.
This shows that the concept of an unmanned factory seems to have begun to reverse. For example, Tesla, which has always regarded unmanned factories as the ultimate goal, has recently faced a big problem. CEO Elon Musk even described Tesla as “production hellâ€. From the perspective of the most used auto industry, unmanned factories may not necessarily As bright as I imagined?
Speaking of unmanned factories, they don't want to go to Tesla. It is well known that Elon Musk has always been a practitioner of robots. He has also proudly declared to the outside world that Tesla has the world's largest and most advanced robotic production line. Especially before the Model 3 is about to be mass-produced last year, it can be seen that Musk has a high hope for the robot production line, with up to 467 Kuka robots, and also acquired a German automated machine manufacturing company to specifically solve the Model 3 production. The demand for production machines.
Subsequently, Tesla re-acquired the US automation equipment manufacturer Perbix, with the goal of being upgraded to a highly automated production line in the future, paving the way for the unpublished Model Y. Musk claims that this highly automated production line will overturn everyone's perceptions, specifically, that humans will completely exit the production line. Instead, the backend is only responsible for maintaining, upgrading, and responding to abnormal conditions. He vowed that "there is really no worker in the future production online, otherwise the production speed will be in line with the artificial speed."
But everything did not go smoothly according to Musk's ideals. This year, the Model 3 production line has been suspended twice. Foreign media revealed that the initial goal of Tesla was to produce 5,000 vehicles per week, but only produced more than 1,000 vehicles at the end of the first quarter.
Although Tesla stated that the production line was suspended to improve automation and overcome the bottleneck of the production line, it is clear that this has exceeded Musk's original expectations, otherwise he will not admit in the media that "excessive automation is a mistake" and that he underestimated humans. Work efficiency.
Musk said in an interview that over-reliance on automation has made the technology of the entire production line more complicated, and these complicated technologies have not been able to perform their intended functions because of frequent problems, and eventually forced Tesla to give up.
Although Tesla is a rising star in the automotive industry, with its innovation and boldness, the market value once defeated many traditional car manufacturers, including 100-year-old Ford, General Motors (GM), and BMW. But from another perspective, the century-old car experience owned by traditional car manufacturers is not something Tesla can surpass in the short term.
If the robot production line is really so skillful, why does the traditional car manufacturer not follow the example of Tesla to hand over the production line to the robot? Previously, the network of BMW robots produced movies. The outside world saw only how robots were assembled quickly, but in fact, human operators have always existed where the lenses were not photographed.
In fact, automakers have long known how to use robots to increase productivity. Observing BMW, it imported 3,000 robotic arms as early as 2007, while using about 6,000 manpower, while the average capacity of a car at that time was 120 hours. By 2017, BMW's production capacity has been increased to an average of 40 hours for a car and a threefold increase for production.
In the past ten years, how has the BMW production line changed? You Hongxiu, head of the Intelligent Robotics Technology Group of the Institute of Mechanical Engineering of the Industrial Technology Research Institute, visited the BMW factory in the field. Surprisingly, there are only 1,500 robots in the BMW production line, but the manpower has increased to 7,700. In terms of man-machine ratio, this is a production model that is completely opposite to the thinking of unmanned factories. However, the results were satisfactory. Although the number of robots has dropped sharply, BMW has not reduced production, but has increased production efficiency.
You Hongxiu observed that the purpose of BMW is not to pursue unmanned factories, but to improve production efficiency and quality. BMW's approach is closer to first stabilizing the process before it is automated. And how does BMW improve production efficiency while reducing the number of robots? The key point is that on the one hand, BMW optimizes the use of the robot arm, and on the other hand, it introduces a cooperative robot to improve the efficiency of human-machine cooperation.
In the use of the robot arm, BMW made some changes. One is to add a lot of sensing technology to the robotic arm, such as visual and force sensing, which makes the robot arm have better coordination, accuracy and sensitivity. It is different from the fixed and repetitive workflow in the past. The robotic arm of the ability will become more elastic.
The second is to introduce the production mode of the Robot Cell. You Hongxiu explained that in this production mode, the robot arm will be assembled between different car bodies through the rotating platform, and the mixed line production can be achieved online in the same production line.
Through the Robot cell, BMW's online robotic arm becomes an versatile one, and only by increasing the use of the robot itself, the factory has the means to maintain or even increase production while reducing the number of arms.
In order to improve the efficiency of human workers, BMW has also introduced collaborative robots that have not been used in the past. Basically, BMW's production line is fully automated and ergonomic, rather than working like Tesla to create a completely unmanned production line.
The industry observed that BMW still maintains the factory's human operations because it understands that it is "too expensive" to develop fully automated unmanned factories at this stage. Although the German car factory is the most enthusiastic supporter in the field of automation, it knows how to evaluate it carefully and knows how to shrink it at the right time.
Especially in Europe and the United States, it is generally recognized that in the future, especially in a small number of diverse production modes, it is more difficult to achieve unmanned production. The most urgent need for flexibility and flexibility in this mode of production is that human beings own the machine. Unmatched at this stage.
Type-C interface has strong expansion ability, can transmit video and video signals, expand to a variety of audio and video output interface, such as HDMI, VGA, DVI interface, and even achieve 4K resolution of the extended transmission. The Type-c interface provides bidirectional power supply, which can charge the device itself or power external devices.USB HUBS has better data transmission capability and higher charging power. USBType-C went into mass production in August 2014, using the 3.1 standard. Compared with the interface of USB2.0 used in early smartphones, the transmission speed is improved a lot, and the maximum data transmission speed can reach 10Gbit/ s. And type-c supports USB-PD power supply standard, the maximum power supply can be up to 100 watts. Different from the traditional USBType-A and Type-B interfaces, the new Type-C interface is slimmed down in size to 8.3*2.5mm, which is more suitable for use in increasingly miniaturized electronic devices.
Supports positive and negative insertion. 100% of the players who use USB interface have encountered the embarrassment of "the positive plug is wrong, the negative plug is wrong, and the positive plug is right". Because USB-C IS POSITIVE AND NEGATIVE CAN be inserted, professional point is to say that the interface does not have directionality, with much more convenient. type-c charging port, support PD fast charging protocol, can be charged while using the computer, not afraid of running out of power. HDMI interface, I like HDMI to support audio and video transmission, high resolution support 4K/2K. Interface is common, LCD TV, monitor, projector are generally also some (like to connect to TV, audio and video synchronous transmission).vga interface, this is a very common interface, most of the projector, monitor have this interface, can be connected to vga line use, support 1080P resolution. Gigabit network port, although now almost everywhere there is a wireless network, but sometimes it is not enough for you, such as playing games, the network speed is slow, delay. And then he dropped the line right in the middle of his victory. So if you have a network cable and you can connect directly to the Internet, it's great to support gigabit networks.
