Automated Assembly Machines: A Selection Guide

Leave a Comment

Assembly line automation allows companies to meet high production demands by performing assembly processes without the intervention of a human operator and moving parts along automated process sequences. Due to the large variety of products that need to be assembled and the different processes each assembly involves, automated assembly machines are almost always custom designed, allowing companies to create a highly individualized solution. This selection guide will describe the most popular types of assembly automation equipment and the benefits they offer.

Choosing the Best Automated Assembly Machine for Your Application

Assembly line automation equipment can be classified into three main styles: factory, manufacturing, and robotic automation equipment. 

  • Factory automation equipment. Factory automation machines perform general movements, such as lifting or lowering. 
  • Manufacturing automation equipment. Manufacturing automation machines are designed to assemble a specific product and can be very fast and efficient. They usually run faster than a robotic assembly station but lack the flexibility that a robot can provide. Custom built machines are designed to run one part with a minimum number of variations. They can also perform quality control and other tasks related to general manufacturing. 
  • Robotic automation equipment. Robotic automation equipment involves more technical machinery that can perform assembly, material handling, painting, or other more sophisticated tasks. This equipment can be very flexible; once a robot is programmed, it can switch from one product to another by simply selecting the product on a menu.

All types of assembly operations involve bringing together two or more parts to form a different product. Assembly operations that can be automated range from welding, stapling, gluing, screwing, pressing parts together, inserting, riveting, clinching, and many more operations that join components. To facilitate these operations, various types of automated assembly machines can be used, including: 

  • Marking systems: In the current manufacturing ecosystem, traceability of assembly components is common and sometimes mandatory. Marking systems (laser marking, ink jet & micro percussion) enable manufacturers to add important pieces of information to parts to facilitate product traceability in the production line. 
  • Testing systems: Automated testing can be performed during the assembly process or at the end of the line when the assembly is complete.  All types of testing can be automated, including functional tests, dimensional inspection, detection of components, noise detection, functional tests, and many more operations that guarantee that the final assembled product meets the required quality criteria.
  • Leak detection systems: This type of automated equipment can test products after they come off the line, or it can be integrated into the production line to test products during manufacturing. In large production operations, manual sniffing, pressure decay systems, bubble checks, flow systems, or spraying can be time-consuming. Automatic leak detection solutions facilitate a much higher-detection speed with minimal operator input. 
  • Welding Systems: Weld quality depends on two factors: weld integrity and repeatability. Automated welding systems utilize electronic weld process controllers to ensure weld integrity. These components also allow for repeatable input parameters, resulting in consistent output. For example, we can make hot plate welding machines with different welding plates in different positions that weld at the same time. 
  • Pick-and-place robots: Pick-and-place robots grab incoming components from a feeding conveyor, vibratory bowl feeder, or tray and place them into the assembly or packaging containers. 
  • Inspection systems: Vision systems or vision sensors inspect a component’s dimensions, color, quality, and other details without physically touching them. In-line inspections offer earlier identification of defective components and significantly reduce the usage of out-of-spec parts. 
  • Palletizers: Using either conveyors or robotic equipment, palletizers automate the palletizing process, dramatically reducing employee injuries as well as the amount of time needed to lift and move heavy components. In manufacturing applications, robots remove products from the production line and load them onto a pallet. 

Automation solutions like robotics, inspection, leak, and welding systems solve many types of production-related problems. Automated assembly machines from AMD can help you achieve a semi- or fully-automated production line that improves workplace safety while reducing manufacturing costs. We can help you create the most suitable type of assembly line automation for your business, including:

  • Fully automated: Fully-automated assembly lines require little to no human interaction to complete production processes. Workers simply monitor machines for issues and replenish parts as needed.
  • Semi-automated: Humans work alongside machines, performing tasks like loading parts into tooling and other fixtures or moving components from one automated station to the next. 
  • Lean manufacturing automation: Manufacturers only incorporate automated solutions that add the most value into the assembly process, creating the highest ROI. 
  • High-throughput manufacturing automation: Continuous motion technology like servo-based or mechanical cams, machine vision, and tooling are used to dramatically increase throughput speeds and reduce cycle time.

Automation and the Future of Appliance Manufacturing

Leave a Comment

Assembly machines and robotic technology contribute significantly to the appliance manufacturing industry. They’re highly effective in smaller assembly applications, putting together household appliances like toasters, irons, or vacuum cleaners. However, for companies that manufacture high volumes of large white goods like clothes washers or refrigerators, in many cases, robots currently handle only those tasks that aren’t part of the assembly process, like stamping, machining, painting, and product testing.

As the market continues to evolve with innovations in automation technology, furthering robotics integration into the appliance industry’s assembly lines for large appliances is the logical next step. Appliance manufacturers can achieve an optimal return on their investment with faster, more accurate, and highly efficient production processes that provide the benefits of operational flexibility and decreased costs.

Appliance manufacturers have to consider automation when designing new products to make its use favorable. This concept means including features in the different components that make it easy for an automatic system to orient them and assemble them into the product, taking into account that the robot will always make the same trajectory and movements and doesn’t have the capability to make small tweaks or process modifications to force an assembly to happen. Manufacturers have to update the design of the appliance to make full use of the capabilities that an automatic system can provide instead of trying to have robots do the tasks that humans do or are good at doing.

Growing Demand for Automation in Appliance Manufacturing

After the automobile industry, the appliance manufacturing sector comes in as the second-most automated industry worldwide. From toasters to refrigerators, appliances all utilize complex electrical components that manufacturers must carefully assemble, welding them on the production line. Robotic automation allows manufacturers to achieve significant savings in appliance production time as compared to manual processes.

Boston Consulting Group Inc. (BCG) found in 2015 that robots completed a mere 10% or so of tasks in manufacturing operations. However, the same study anticipated an increase to 25% by 2025, with the largest growth projected in the appliance and electrical equipment industries. BCG reasoned that the high wages for human workers in these sectors and the abundance of tasks into which manufacturers can easily incorporate automation would hasten global robotics adoption in these fields.

Benefits of Automation in Appliance Manufacturing

In a world where automation is becoming the norm, it’s important to understand how the appliance manufacturing industry can capitalize on its benefits. Compared to manual operations, automation offers superior:

  • Precision. Automation allows companies to increase accuracy within their assembly applications for greater uniformity and repeatability. Robotic technology reduces or eliminates the risk of human error, producing higher-quality products for your market.
  • Speed. Automation increases production speeds, efficiency, and throughput without having to sacrifice quality in large appliances like refrigerators, stoves, washers, and dryers. It positions manufacturers to be successful and keep up with businesses while operating in a highly competitive market.
  • Flexible, scalable operations. Manufacturers can quickly adapt robotic technology to production changes, like an altered design or product modification, without necessitating a revision to the actual assembly line. Also, the enhanced productivity allows manufacturers to scale their operations as needed.
  • Integration capabilities. The ease with which manufacturers can incorporate turnkey automation solutions into their current operations and machinery allows them to seamlessly automate complex processes that would otherwise cost them in greater time and labor investments.
  • Adherence to industry/regional quality standards. Automation in appliance manufacturing boosts compliance capabilities as the equipment will assemble all appliance parts and equipment per the highest quality standards to meet industry or regional requirements.

Improvements in Automation

Robots are becoming smarter and more beneficial than ever in appliance manufacturing. BCG projected in 2015 that robotic systems’ improvements in flexibility, production speed, and related advantages would continue at a rate of approximately 5% per year. This versatile, highly networked technology is already utilizing advancements like gripping systems and vision sensors to improve and expedite processes.

While the initial investment for automated equipment has traditionally been more cost prohibitive than that of human labor, continuous innovations in information technology and robotics, along with the resulting improvements in assembly line performance and product pricing, will eventually lead to automated practices being the more cost-effective of the two. Incorporating automation now will help appliance manufacturers gain a competitive advantage before 100%-automated assembly lines become fully mainstream in the industry.

Including robots in assembly lines is one option for automation in the appliance industry, but manufacturers can automate many other processes as well, like punching or drilling holes in cabinets, clinching or riveting components, making functional testing, etc.
