Every year, Apple's new machine will undergo a "special treatment" for a period of time. Violence will take snipers, mixers, and gasoline. The most common ones are disassemble, X-ray, etc., and teardown is also essential for mobile phone repair. In the last part, I remember the Apple dismantling robot, Liam, which was officially launched by Apple in the spring of last year. Recently, Apple released a Liam white paper with the 2017 annual environmental report; although this is for the recycling service. But still able to subvert everyone's understanding of the simple process of "disassemble."
Fever School: The same is to remove the phone How does Apple do it?
The pretreatment recycling industry of used consumer electronics has often relied on efficient automatic crushing systems, and the quality and quantity of recycled materials produced is not high enough to achieve the desired recycling effect. To this end, Apple's R&D department launched Liam, a project focused on the new dismantling of used consumer electronics technology, using automated and clean decomposition processes to disassemble different components and recycle specific materials; the current Liam for iPhone 6 The model is designed to dismantle and recycle 1.2 million used mobile phones every year.
Traditional crushing and sorting process
The pulverization and sorting, that is, the complete or preliminary decomposition of the electronic product is pulverized into finely divided granules by a pulverizer, and then cooperated with the metallurgical enterprise to extract the precious metal in the granule by the molten pool smelting technique.
Traditional crushing and sorting process
The crushing and sorting was born in the era of large and small quantities of electronic components. It is relatively easy to pulverize and recycle metals. At present, the miniaturization and precision of electronic products undoubtedly make this technology fall behind and is used in electronic products. The exponential growth in the number of metallic elements has also made this traditional technology increasingly difficult to recover certain types of metallic elements.
29 independent robotic arms make up Liam
For how to completely dismantle the damaged iPhone, Apple claims that Liam will use two main processes to disassemble the parts: First, the end tool (EOAT, such as a drill bit, suction cup or fixed end) will break down the fixed iPhone. Second, Liam's 29 independent robotic arms interact with externally active tools to perform complex coordinated movements.
The iPhone component that was eventually broken down consisted of six main components: the screen assembly, the battery, the motherboard, the speakers, the receiver, the vibration unit, the rear camera, and the casing.
Heating separation and disassembly battery
If you follow the manual disassembly method, the iPhone 6 battery and almost all iPhone batteries in recent years need to be removed, uncover the disposable tear tape at the bottom, carefully pull all the batteries away; according to the size of the iPhone There may be two or three pieces of tape in the size. If you continue to take down the battery in the middle of the process, it is very simple. The most painful thing is to pull off which one... This is going to be rough.

The Liam robot obviously does not use this manual method, but in principle it is also common when manually disassembling, that is - heating. Liam's disassembly process for the iPhone 6 battery has been removed from the screen assembly, the battery cable has been separated from the fuselage, the phone is placed on a special workbench, and the external heating module is used for the bottom of the fuselage. After 5 seconds of heating, after the battery tear tape is loosened, the battery is taken out by a robotic arm equipped with a vacuum chuck.

Throughout the process, the heating module, which may cause safety hazards, is always at the safe temperature defined by the Apple Battery Engineering team. Once the battery is removed, it is sent to the cooling process to meet EH&S standards (Environment Environment, Health Health and Safety Safety). The temperature of the abbreviation), so as not to cause ginseng damage to the next operator; finally the battery is sent to the conveyor to leave the "sandbox" battery disassembly system.
a sandbox that prevents the battery from overheating during the disassembly process
In the event of a battery fire emergency, Liam also has a stupid and effective response, covering it with sand... This is probably the reason why the battery disassembly system is called the "sandbox".
As for the method of disassembling the speaker module, it is simpler and more rude, because other components around the speaker module are not suitable for individual operation. The iPhone 6 body clamped by the robot arm will be inserted into a wedge under the speaker module. With the overall rotation of the arm, the speaker module will be easily "snapped" and then directly sent to the recycling bin.

The other part of the white paper that broke down Apple did not mention that the Liam video at the last press conference last year was probably good.
Increase the reuse rate of rare earth elements
Unlike the traditional smash sorting method, Liam's disassembled mobile phone is in the form of components, rather than broken components, as the destination of these components, because each generation of iPhone configuration is different. It is unlikely to be a "refurbishment" that will make up the future of mobile phones.

The disassembled components are sent to other manufacturers for subdivision of metal extraction. Apple says that Liam can extract more precise types of elements than traditional smash sorting methods, such as magnetic components that were previously impossible to extract. The rare earth elements are lanthanum, cerium and lanthanum. According to Apple's 2017 environmental report, every 100,000 iPhone 6, Liam is expected to recover 1900kg aluminum, 800kg copper, 300g gold, 400g platinum group metal, 7kg silver, 55kg tin, 24kg rare earth element, 550kg cobalt, 3.5kg tungsten , 2.5kg é’½.
Finally, maybe you feel like I have to use a vibration unit to get rid of it. Can you make a XX together? Fortunately, this is Apple, not Lelo, so it becomes a screwdriver...
The energy storage Wire Harness is a very important part of our life. Among the different products we use every day, the energy storage power harness also plays a lot of decisive roles. The load source of the energy storage wire harness is the service object of the harness, which usually refers to user equipment; broadly speaking, the upper-level equipment is the load source of the lower-level equipment. The energy storage wire harness and the more rational use of electricity and various signals have made our lives have better practical effects. In fact, what really helps us achieve these effects is that we look at the inconspicuous energy storage power supply. Wire harness, toy wire, terminal wire, PU wire and other wires. It is with these wires that our lives are better, and we have obtained more ideal quality of life. Although these wires have never been valued by us, the use effect and value of these wires are very important to our life. Life is very important. The air tightness test of the loose blind plug was carried out on the energy storage power supply wiring harness, and it was found that its waterproof sealing performance was greatly reduced, and it was easy to fall off, and there was a great risk of water ingress corrosion. Therefore, measures must be taken for process or design optimization.
Kable-X always believes that talents are the key to the development of the company. Talent first is Kable-X`s unchanging commitment, especially in the construction and investment of R&D teams for custom wiring harness. Based on R&D and design, it continuously improves its technical strength and is targeted. The projects are implemented one by one, and the company's technical development level is continuously improved through the training of talents.
Therefore, our high-end custom Cable Assembly is recognized by our customers, and we can meet customer needs. Especially our Medical Custom Cable Harness, including Ventilator Wire Harness and Medical Power Wire Harness, etc.
