The rapid iteration of the consumer electronics market has led to a demand for speakers that is characterized by "small batch, multi-category, and fast delivery".

A research shows that the electro-acoustic enterprise order batch than three years ago increased by 200%, single batch volume decreased by 60%, the traditional fixed production line changeover time of up to 8 hours, it is difficult to adapt to the market rhythm. How to balance production efficiency and order response speed through flexible automation technology has become a common problem in the industry.

The core pain point of multi-category production is the balance between change efficiency and production accuracy. Traditional production lines need to manually adjust more than 15 parameters when replacing product models, and fixtures are prone to installation deviation in the process of changing models; the debugging cost of small-volume orders accounts for as high as 30%, and the time cost of manual testing has risen significantly; there are large differences in the processes of different categories, and a single production line is difficult to be compatible with cross-category production from automotive speakers to headphone speakers.

The flexible automation system realizes compatible production through three major technologies. Adopting modularized fixture design, the quick locking mechanism shortens the changeover time to 30 minutes, and with the parameter memory function, more than 100 kinds of product parameters can be recalled by one key. In the testing process, a universal acoustic testing platform is developed, and the automatic transducer adapts to speakers of different sizes, with a testing coverage of 981 TP3 T. The introduction of digital twin technology allows the debugging of new products to be completed in a virtual environment, which reduces the debugging time by 701 TP3 T when the products are actually put into production.

After the commissioning of JiuJi Automation's horn automation flexible production line, it can be compatible with the production of 120 different specifications of horns, and the order delivery cycle has been shortened from 15 days to 5 days, and the gross profit margin of small-volume orders has been increased by 12 percentage points. This proves that flexible automation has become the core production mode to cope with the rapid changes in the market.
