Information briefs for the week check out the brand new development in manufacturing known as microfactories—the place robots rule, a first-ever, ready-to-use 3D printing cupboard, T-skin security sheathing for cobots and industrial robots, and a do-it-yourself 3D printed cobot for desktop manufacturing.
Microfactories: The place robots rule!
Are microfactories the way forward for manufacturing? There’s a manufacturing unit automation development that’s simply starting to take maintain that deviates radically from the usual meeting line, particularly these in auto crops. Korea’s Hyundai has constructed such a very completely different auto plant for its electrical car manufacturing (EV) in Singapore.
The Hyundai plant is made up of pods or cells the place 60% of the manufacturing of the Ioniq 5 EV is completed by robots (see video); the remaining 40% is accomplished by human staff alone or in partnership with robots.
The online-net in the case of workers is that it makes use of solely 100 staff to provide 30,000 autos a yr. In pod assemblies, robots rule!
Alpesh Patel, VP of Innovation at Hyundai, thinks {that a} microfactory’s cell manufacturing technique may nicely be normal in just a few years. Total value discount to fabricate is 50% lower than a conventional or totally customized automated line. “It’s because modules use 70% of the identical elements (body, energy, security, conveyor system).” Plus, growth and meeting time is usually 50% lower than a completely automated customized line.
“Within the cells” writes Suvrat Kothari, “robots set up elements of a automotive, earlier than transferring to the subsequent zone. The important thing differentiator is that the cells may be programmed with particular directions, proper from putting in elements for various variants of the identical automotive, or to engaged on a very completely different mannequin. Conventional meeting strains would wish important retooling for related adaptability.”
The cells are linked collectively by a typical conveyor and feeder system, able to offering excessive quantity, excessive combine manufacturing functionality.
Modular automation can scale up or down simply. “Relying on the complexity of the product or sub-assembly, producers can simply count on to get 3-4k models’ per hour (UPH), or 1 million models a month.”
Prepared-to-use 3D printing robotic
Market want: Prepared-to-use, turn-key system offering an environment friendly, quick, and secure resolution for manufacturing metallic 3D printed elements, particularly with stainless-steel, nickel, and titanium. To fulfill the necessity, Spain’s Meltio and US-based One Off Robotics partnered for the manufacturing of a self-enclosed 3D printing cupboard.
Meltio is a producer and developer of wire-laser metallic 3D printing applied sciences, and One Off Robotics is a builder of robotic arm fabrication programs for additive, subtractive, and hybrid manufacturing processes.
In combining their applied sciences, they declare a first-ever, turn-key resolution to supply industries with an environment friendly additive manufacturing work cell named the One Off Robotics Cell. In response to Meltio Product Supervisor, Alejandro Nieto, “This new {hardware} system permits the shopper to obtain a ready-to-use cell for robotic metallic 3D printing, eradicating the mixing course of and lengthy meeting lead instances.”
With a deposition fee of as much as 1 kg an hour, this method produces totally dense elements which might be mechanically equal or superior to these created from conventional means.
The One Off Robotics Cell seamlessly integrates management of the system, permitting the consumer to simply alter settings for fast printing. Its 8-axis system simplifies printing of advanced geometries and is configured to work with the Meltio Area robotic slicer.
Security pores and skin stops robots immediately
Preserving staff secure from cobots has all the time been a priority; extra so with cobots than normal industrial robots, that are normally segregated from staff by fencing or partitions.
In 2016, FANUC launched contact-sensing cobot security padding which had been polyurethane foam pads utilized to the outside of cobot arms. Stopping time in 2016 was 9 milliseconds.
Almost ten years on, Taiwan-based Touche Options (previously named Mechavision) has lately developed a contact-sensing movie of security materials that’s additionally utilized to the outside of not solely cobot arms but additionally to these of commercial robotic arms. Referred to as T-skin, it has a stopping time of 1 millisecond. Need to understand how lengthy a millisecond is? Try the video beneath.
Touche Options’ founder and chairman, Camus Su, and common supervisor, Liu Changhe, are graduates of the Industrial Expertise Analysis Institute (ITRI). Their collaboration in 2017 led to Touche Options, which emphasizes “tactile sensing know-how to set off emergency stops in robots, serving as an important security measure past visible and light-weight grids.”
The founders declare that T-Pores and skin, was developed based mostly on the ISO normal unit of 10 newtons (1kgf) that triggers emergency stops in response to an exterior power of 1 kilogram, inside 1 millisecond, and is unaffected by both electromagnetic waves or RF.
A major goal of Touche Options is “to outfit conventional industrial robots with collaborative [cobot] capabilities, which has garnered fast recognition from main Japanese robotics firms (FANUC, Kawasaki, and so on.).
All of because of this industrial robots can now, with the addition of T-skin, tackle jobs previously meant just for cobots working in and round folks.
DIY 3D printed desktop cobot
Received a small-shop enterprise with a number of desktop manufacturing wants? Want a strong instructional cobot arm for studying tasks? Need to market and promote cobots on-line to a worldwide viewers? Introducing the award-winning PAROL6 (Supply Robotics).
Roboticist Petar Crnjak is hoping to convey industrial-style robotic arms to a wider viewers with an open-source 3D-printable six-axis design dubbed the PAROL6 — providing assist for a powerful 2.2lbs (1kg) payload.
Crnjak says his “PAROL6 is a high-performance, 3D-printed desktop robotic arm, with a design method just like ” of his creation. “The design method of PAROL6 was to be related “to industrial robots by way of mechanical design, management software program, and value. Management software program, GUI [Graphical User Interface], and PAROL6’s STL recordsdata are open supply.” Except for a pneumatic gripper, every axis is pushed by a stepper motor, with a minimum of just a few of those axes being pushed by way of a metallic planetary gearbox for additional precision and torque.
Relying on ones’ stage of experience, PAROL 6, with entry to a 3D printer and on-line design specs (free), it may be a DIY undertaking; it additionally is available in package type; or bought able to go straight out of the field for $3.200 (3,000 euros).
“By pairing industrial mechanical design with state-of-the-art software program and electronics, the PAROL6 robotic can obtain easy motions, excessive speeds, and excessive repeatability. PAROL6 is constructed with training, analysis, and small automation in thoughts!”
