With each technological advancement, products become increasingly sophisticated and compact. Take mobile phones as an example. In the 1990s, the "brick phone" was all the rage, but many joked that it was a huge brick. Today, however, mobile phones are no longer those bulky bricks; they have become extremely thin and light, and there are even concepts like "paper-thin phones" being proposed.
However, each new product launch places new demands on technology and processes.
So what exactly is this so-called technology and process now?
Let's take the screw-locking process, a breakthrough point in automation, as an example to briefly discuss.
Taking the simple screw-fastening process as an example, handheld electric screwdrivers are still the mainstream method for screw fastening. Most screw-fastening stations rely on manual labor, which easily leads to problems such as missed screws and stripped threads. This technology can no longer meet the tightening requirements of the vast majority of electronic products on the market.
Taking the tightening of a mobile phone circuit board as an example, continuously tightening it might damage the board. Therefore, a multi-step tightening process is necessary: first screw it in, then reverse it to come out, to avoid immediately locking it. Immediately locking it might damage the circuit board when subsequent screws are tightened. Therefore, instead of tightening immediately, leave some space and tighten the final screw after all the screws are basically in place. This method efficiently meets the product tightening requirements.
However, not all electric screwdrivers can perform this multi-step tightening. Some might argue that manual tightening can also be done. While it's true that manual tightening is possible, it falls far short in terms of efficiency and precision. Mobile phone screws are already quite small, making it impractical to rely on manual tightening for extended periods.
Airt servo electric screwdrivers can efficiently solve this problem. Airt servo electric screwdrivers use Tamagawa permanent magnet synchronous motors and drivers, and feature dedicated servo control algorithms. They offer significant advantages over ordinary screwdrivers using DC and stepper motors in terms of tightening consistency and lifespan. Beyond screw tightening, they also include tightening programming, pass/fail statistics, result analysis, record tracking, and data interaction. With 12 task modes and 8 parameters per task, totaling 96 parameters, they can adapt to various complex tightening processes.
