Charged EVs | Enhancing velocity to market: Navigating EV meeting challenges


Sponsored by Bosch Rexroth

The electrical automobile (EV) revolution features extra momentum day by day, driving change to automotive manufacturing in unprecedented methods. With quickly rising demand comes the necessity to quickly scale meeting operations — and that may create important challenges. 

Car producers consistently search new, extra productive automation applied sciences to spice up their high quality and productiveness. Together with many widespread meeting workflows, they face new challenges related to scaling up battery pack and e-axle manufacturing. They want automation options to assist combine electrical battery and powertrain manufacturing seamlessly into general meeting processes. 

Bosch Rexroth has an industry-leading portfolio of automation expertise to fulfill these wants, with many years of expertise offering manufacturing and automation options to main automotive OEMs, in addition to Tier 1 and Tier 2 suppliers. 

Broad vary of meeting challenges

Electrical autos have changed engines, gasoline tanks and transmissions with electrical motors, regenerative braking expertise and superior battery packs. Assembling these new parts presents distinctive challenges; on the similar time, there are meeting processes widespread to each EV and inner combustion (IC) automobile meeting traces.

For instance, EVs have physique elements which might be welded utilizing high-speed six-axis robots with superior welding controls. Extraordinarily exact management of weld high quality is vital to the long-term efficiency of the automobile; poor welds can result in separation and vibration in physique elements over time.

To unravel these complicated welding challenges with most velocity and absolute high quality management, Bosch Rexroth has launched the PRC7000 welding controller platform. 

The PRC7000 expands the variety of warmth blocks out there, so plant operations can customise welding to particular throughput and materials traits — a serious benefit over older-generation techniques. Additionally, it may well retailer as much as 10,000 welding packages that may be simply constructed through a drag-and-drop interface to include extra refined welding sequences.

Enhancing handbook meeting

Although EV vegetation are extremely automated, additionally they use the most recent handbook meeting strategies to put in a variety of parts and techniques. Assemblers set up headlights, windshields, retractable sunroofs, seats and door and window controls, usually additionally connecting them to the automobile’s management module. Actual precision on this course of is vital to ship autos that function as flawlessly as attainable.

Bosch Rexroth provides a sophisticated portfolio of clever tightening instruments to offer the productiveness and high quality management wanted for these handbook processes. They supply the exact, repeatable efficiency essential to high-volume meeting traces. The portfolio consists of the EXACT ION collection of cordless screwdrivers, providing industry-leading accuracy, sturdiness and vitality effectivity, in addition to ergonomic design and decrease weight to reinforce employee consolation.

Wider use of those sorts of i4.0-ready instruments helps meeting traces enhance throughput and function with larger flexibility as completely different automobile fashions transfer by way of the road, whereas on the similar time producing vital information that plant operators can use to enhance coaching, alter workflows and apply lean manufacturing rules. 

A number of applied sciences to spice up battery pack manufacturing

There are 4 main steps in battery pack manufacturing widespread to most operations: electrode manufacturing, cell meeting, module meeting and pack building, which additionally sometimes consists of end-of-line battery testing. 

Charged EVs Improving speed to market Navigating EV assembly

Every stage makes use of a posh array of automation applied sciences to go from uncooked supplies to accomplished packs. Given the vital function of the battery within the long-term efficiency and worth of EVs, battery manufacturing requires excessive throughput charges mixed with extraordinarily tight meeting tolerances and high quality management techniques. 

In electrode manufacturing, uncooked supplies transfer by way of a number of automated processing steps. Maximizing management over these processes requires applied sciences that guarantee cells are created with desired electrochemical properties, lifecycle and vitality density.

Bosch Rexroth’s ctrlX AUTOMATION platform options superior controller and drive techniques designed exactly for these high-throughput manufacturing processes. The ctrlX CORE controller supplies superior closed-loop sag and loop management to eradicate breakage and reduce waste. It additionally helps high-speed multi-axis synchronization for internet velocity and place alignment.

In cell manufacturing, particular person batteries — cylindrical, pouch or different format — are mixed into cells. Many producers are working to optimize the stacking course of on this step as a result of streamlining stacking can enhance the throughput of the whole line. 

Excessive-speed robotic dealing with techniques, both delta robots or linear robots, are important instruments on this stacking course of. The Good Operate Package for Dealing with is a extremely environment friendly linear robotic choice well-suited to this course of step. It’s actually plug-and-produce: trendy on-line instruments assist fast and intuitive element choice and configuration, and the pre-installed software program permits for simpler commissioning, supporting quicker manufacturing begin and serving to velocity to market.

Modular motion and transport options

Going from uncooked supplies to a examined and put in battery pack presents a serious automation transport problem. With every meeting step, weight and element dimension will increase, so a variety of fabric transport conveyors and different techniques is critical. 

From switch techniques for quickly transferring merchandise weighing a couple of grams to linear motor-driven techniques that may exactly transport as much as over 400 kg, state-of-the-art conveyors and linear motor transport techniques maximize environment friendly use of manufacturing facility flooring house and allow easily flowing, intelligently related manufacturing.

VarioFlow plus plastic chain conveyors are confirmed techniques that quickly transfer cell assemblies horizontally, vertically, round obstacles or built-in with different course of flows. These additionally assist workpiece pallets to convey cell parts the place positioning or increased stopping precision is required.

Additional down the road, Bosch Rexroth provides the linear motor-based Versatile Transport System (FTS). It helps pallet-based transport and permits for particular person provider management for extra complicated motion at quicker throughput charges. Mixed with our intralogistics autonomous cellular robots (AMRs), Bosch Rexroth is uniquely outfitted to deal with nearly each battery manufacturing transport problem.

Profitable meeting traces design conveyor and materials transport options early within the growth course of, not as a remaining step as soon as all of the manufacturing machines and cells have been outlined. This helps guarantee productive motion of merchandise and supplies by way of each course of step and prevents constructing in non-value-added transport time. Bosch Rexroth has deep expertise serving to choose and join completely different transport techniques so the proper materials circulation is established — and will be simply modified as manufacturing necessities evolve.

Automation perception to enhance EV meeting productiveness

As EV producers are beneath strain to broaden manufacturing, they run dangers by merely throwing expertise at their throughput challenges, quite than contemplating how effectively their expertise and element selections work collectively. All this meeting expertise ought to be engineered and harmonized to maximise throughput with out sacrificing the standard of the top product.
