The FASTEST TV Factory Tour - Hisense Qingdao TV Assembly Tour

Quick Overview

The Hisense Qingdao TV assembly tour reveals an extremely high level of automation, utilizing numerous custom robots and AI-driven machine vision systems to assemble large RGB Mini-LED TVs with incredible precision, significantly reducing labor costs and defect rates compared to older manual processes.

Key Points: Hisense's TV factory employs seven first-of-their-kind automated machines for processes like backplate/mainboard installation and component placement. Automation, including robots and AI, reduces the defect rate by over 90% compared to manual processes and achieves assembly precision of 0.02mm. The factory uses a dedicated automated glue dispenser guided by an AI model to apply adhesive to LED light bars, saving 58% in glue consumption and preventing defects. The back-end quality control (QC) uses 3D machine vision and plug-out robots to perform ultra-precise inspections for uniformity and component placement. The final assembly stage, which includes installing the mainboard, power supply, and speakers, is highly automated, with only the final back cover installation requiring human hands. The average weight of a consumer TV assembled here is approximately 54kg (120 lbs), highlighting the need for automated handling solutions like the large robotic arms seen packaging the units.

Context: This video documents a factory tour of Hisense's TV manufacturing facility in Qingdao, China, focusing specifically on the highly automated production lines for their large-format RGB Mini-LED televisions. The tour contrasts modern automation with older, more manual assembly methods, emphasizing Hisense's commitment to technological advancement, efficiency, and quality control in producing cutting-edge display technology.

Detailed Analysis

The Hisense Qingdao factory tour showcases an advanced assembly line where large RGB Mini-LED TVs are manufactured with an extremely high degree of automation. The process begins with automated installation of the backplate, mainboard, and power supply, utilizing custom machinery that achieves a precision of 0.02mm. A key innovation highlighted is an AI-guided glue dispenser that applies adhesive to LED light bars, cutting glue consumption by 58% and drastically reducing defects. Quality control (QC) is managed by 3D machine vision systems that inspect backlight uniformity with high accuracy, replacing older methods that relied on human visual inspection. Furthermore, the factory uses autonomous vehicles (AGVs) to transport materials efficiently across the cleanroom environment. The assembly process is so automated that only a few steps, like installing speakers and connecting delicate ribbon cables, require human workers, who are clad in cleanroom suits. The final packaging stage is also almost entirely automated, using large robots to handle the heavy 54kg (approx. 120 lbs) finished units. The advancements in RGB Mini-LED technology, which uses red, green, and blue LEDs for superior color saturation compared to older FALD and standard Mini-LED techniques, are contrasted against a historical timeline showing Hisense's rapid progression in display technology since 1997.
