Automated assembly systems are used in mass production and can be stationary tabletop versions or installed along conveyor belts. They can be modified with other equipment for improved production times and must be monitored for quality control.
Automated assembly systems are commonly offered in stationary tabletop versions, installed along conveyor belts, and modified with other production line equipment, such as optical bond testers for printed circuit boards (PCBs). These types of systems help companies mass produce goods for sale and distribution. Consequently, their functions must be properly monitored for the best yield of the product.
Stationary tabletop automated assembly systems look like a large human arm attached to a flat tabletop surface. The robotic arm drills, screws, or manipulates an item of manufacture; for example, a cell phone case requires multiple holes around the perimeter to attach the screws between the front and back covers of the device. Automated assembly systems align the housing on the table and drill the lid with the robotic arm. As a result, the housing has precisely placed holes, set at a rapid pace, to keep production rates high.
Conveyor belts move production parts at a particular speed for controlled manufacturing. Normally automated assembly systems are placed along the beltline at strategic points; area “A” can have a washer placed on a bolt by a robotic arm while area “B” uses another assembly branch to secure the end nut on the washer and bolt setup. A worker can monitor one or more robotic arms along the conveyor belt to ensure that each station is operating within stringent specifications.
Common production line equipment can be modified with automated assembly systems for improved production times. Robotic arms can be placed on an optical tester to align a newly constructed printed circuit board (PCB) with illuminated internal optics; misalignment can lead the tester to believe the board is defective, which can reduce production time. Proper alignment of the computer and robot ensures proper machine operation.
Another modification of the machine for automated assembly systems is the pick and place device. A well-maintained machine will use a robotic arm to choose the correct electronic component for placement on a new PCB; the tiny components must be oriented in a specific position for the circuit to work properly. Human pick and place assembly is prone to errors as components are easily misaligned or chosen incorrectly.
These robotic systems cannot be overlooked by workers or management. Each machine must be monitored during use and adjusted accordingly; every product that emerges from the system should be inspected for quality. Problems that arise during the production day should be identified and resolved in a timely manner for the best production rates.
